3295 check-ins using file src/mem5.c version b7da5c10a7

2024-05-02
19:22		Fix a problem with queries that use "IN(...) ORDER BY ... NULLS LAST" or similar introduced by [d7648e21605a0b38]. (Leaf check-in: 26b2d9390f user: dan tags: trunk)
18:16		Avoid an assert failure accessible only when internal testing features are enabled. dbsqlfuzz crash-66abacda6bca6bd531e25595e8c8068e2c710326.txt. (check-in: fbc446daac user: dan tags: trunk)
17:46		Fix a case where the recovery extension might write uninitialized data to the recovered database. (check-in: 8519b4d039 user: dan tags: trunk)
14:48		Avoid an OP_Next in cases where an IN(...) query against a UNIQUE index may return at most 1 row. (check-in: d7648e2160 user: dan tags: trunk)
12:14		Fix the CREATE TABLE performance issue described by [forum:/forumpost/4cf69794d9dfff7c\|forum thread 4cf69794d9dfff7c] in two different ways: (1) Omit the call to PRAGMA integrity_check('X') that was being done after CREATE TABLE "X" because the result was being ignored and the integrity_check was not doing anything other than burning CPU cycles. (2) Do not interpret the argument to PRAGMA integrity_check as a number if it is in fact a string that looks like a number. (check-in: 71f08b9122 user: drh tags: trunk)
12:00		Add a test case to the fix to PRAGMA integrity_check in the previous check-in. (Closed-Leaf check-in: 39a57b596d user: drh tags: faster-create)
11:52		Do not accept a string that looks like a number used as an argument to PRAGMA integrity_check as a number. Treat it as a table name that just happens to look like a number. (check-in: b04e7a2347 user: drh tags: faster-create)
11:51		Omit the OP_SqlExec to "PRAGMA integrity_check" added by [348fa7aaf7958b3f] because it is a no-op. Even if the integrity_check failes, the CREATE TABLE is stull successful. The OP_SqlExec just burns CPU cycles for no reason. (check-in: 532795acd1 user: drh tags: faster-create)
2024-05-01
19:48		Avoid an OP_Next in cases where an IN(...) query against a UNIQUE index may return at most 1 row. (Closed-Leaf check-in: 560f64157d user: dan tags: unique-in-opt)
16:25		Fix another problem in the recovery extension where a corrupt sqlite_schema table could lead to excessive memory consumption. (check-in: 1c7e33a8aa user: dan tags: trunk)
14:42		Fix a problem causing the recovery extension to use excessive memory and CPU time in some cases. (check-in: 8de85170d5 user: dan tags: trunk)
2024-04-30
19:34		Avoid 32-bit overflow when calculating ncycle for ".scanstats vm". (check-in: 2858efa06d user: dan tags: trunk)
2024-04-26
19:10		Fix issues in LIMIT/OFFSET support for virtual tables. The first problem was reported by [forum:/forumpost/c243b8f856\|forum post c243b8f856]. That report prompted an enhancement to the generate_series() (also included in this merge) which in turn identified other similar issues. (check-in: 5f6c079d84 user: drh tags: trunk)
18:42		Internal JS doc touchups. No functional changes. (check-in: 626b997b4e user: stephan tags: trunk)
18:24		Additional internal docs in the wasm utilities. (check-in: 5a2245a9eb user: stephan tags: trunk)
18:13		Allow virtual table implementations to handle OFFSET but not LIMIT, but not LIMIT but not OFFSET. (Closed-Leaf check-in: 90e5c8226a user: dan tags: vtab-limit-fix)
17:19		Have where.c ignore any plan from a virtual table that tries to use LIMIT/OFFSET without also using all WHERE constraints. (check-in: 7d30596496 user: dan tags: vtab-limit-fix)
17:09		Further fixes and improvements to the generate_series() enhancements on this branch. (check-in: b7d9bd7ee2 user: drh tags: vtab-limit-fix)
14:36		Use hex flag masks rather than decimals in ext/misc/series.c. (check-in: a94e2cd028 user: drh tags: vtab-limit-fix)
14:32		Fix a problem allowing a LIMIT constraint to be passed to a virtual table in cases where there exist WHERE terms that cannot also be passed. (check-in: 72c8ed9698 user: dan tags: vtab-limit-fix)
13:38		Fix handling of LIMIT and OFFSET in virtual tables that are part of a compound SELECT. (check-in: 40421c1c4e user: drh tags: vtab-limit-fix)
13:30		Enhance the generated_series() table-valued-function to respond to LIMIT and OFFSET. Use this to add new test cases for LIMIT and OFFSET on virtual tables in a compound SELECT. (check-in: 408d47ecaa user: drh tags: vtab-limit-fix)
12:01		Add test demonstrating the problem at [forum:/forumpost/c243b8f856\|forum post c243b8f856]. No fix yet. (check-in: 1685495c0a user: dan tags: vtab-limit-fix)
11:32		Fix the TreeView display of a LIMIT clause on a compound query. Debugging code only - not part of production builds. (check-in: 38f1e5ce4e user: drh tags: trunk)
2024-04-25
23:26		Improvement to the way that affinity is determined for columns of a compound subquery. The affinity is the affinity of the left-most arm of the compound subquery that has an affinity other than NONE, adjusted to accommodate the data types coming out of the other arms. (check-in: e6df846f36 user: drh tags: trunk)
17:52		Further improvements to the computation of affinity for compound subqueries: make sure that the selected affinity is compatible with a literal values in arms to the left of the arm that is used to determine affinity. (Closed-Leaf check-in: bbdf22e3d9 user: drh tags: compound-subquery-affinity)
16:55		Back out the previous change on this branch. In its place: Determine the affinity of a subquery by the left-most arm of the subquery that has an affinity other than NONE. In other words, scan from left to right looking for an arm of the compound subquery with an affinity of BLOB, TEXT, INTEGER, or REAL and pick the first one found. Or stay with NONE if no arm has a defined affinity. Test cases added. (check-in: b8ec8511b1 user: drh tags: compound-subquery-affinity)
06:52		wasm: add a makefile comment about the static sqlite3.h/c version info injected into the JS files possibly differing from the runtime-emited version info when a user provides their own sqlite3.c. (check-in: d99a01a0f6 user: stephan tags: trunk)
2024-04-24
19:49		An experimental minor tweak to the way affinities are computed for compound subqueries, when the actual affinity is ambiguous. (check-in: 779723ad79 user: drh tags: compound-subquery-affinity)
16:36		If a RETURNING clause contains a subquery that references the table that is being updated in the statement that includes the RETURNING clause, then mark the subquery as correlated so that it is recomputed for each result and not just computed once and reused. See [forum:/forumpost/2c83569ce8945d39\|forum post 2c83569ce8945d39]. (check-in: 9ea6bcc8fd user: drh tags: trunk)
14:18		Fix a case where a corrupt stat4 record could go unrecognized due to integer overflow. (check-in: 240a4a48b2 user: dan tags: trunk)
11:51		Add comments linking the assert() added in [cef4d9e3ba586735] to the places where the precondition that the assert() tests are actually required. (check-in: 6f0e7e1952 user: drh tags: trunk)
11:40		Avoid slowdown when exprNodeIsConstant() is called on deeply nested SQL functions. (check-in: 1c0b034545 user: dan tags: trunk)
11:21		Ensure that temporary SrcItem objects created by trigger processing have either SrcItem.zName or SrcItem.pSelect defined. Every SrcItem should have one or the other. (check-in: cef4d9e3ba user: drh tags: trunk)
06:43		Remove an undocumented feature from the JS Worker1.open API because it relies on broken behavior which has no VFS-agnostic workaround. (check-in: 3a640038c7 user: stephan tags: trunk)
2024-04-23
12:02		Fix a problem with vector IN operators used with an index where the affinities and collations for the various vector terms are different. (check-in: 86e8c782e7 user: drh tags: trunk)
11:56		Fix an uninitialized variable problem in the new code on this branch. (Closed-Leaf check-in: 85625b3871 user: dan tags: vector-in-fix)
06:49		Remove some dead WASM-side code. (check-in: 0a07ee27bd user: stephan tags: trunk)
06:36		Minor touchups in JS docs and exception messages. (check-in: 9e7fc9370d user: stephan tags: trunk)
05:38		When running the 'dist' target in ext/wasm for an SEE-capable build, ensure that the resulting zip file and directory name include '-see'. (check-in: 04c552b12e user: stephan tags: trunk)
2024-04-22
20:09		Add extra tests for aborting conflicts in the sessions module. (check-in: b4a6d32662 user: dan tags: trunk)
17:03		Minor cleanups to [8fbda563d2f5]. (check-in: 5ee2594b65 user: stephan tags: trunk)
16:46		Extend the JS/WASM SEE build support by (A) filtering SEE-related bits out of the JS when not building with SEE and (B) accepting an optional key/textkey/hexkey option to the sqlite3.oo1.DB and subclass constructors to create/open SEE-encrypted databases with. Demonstrate SEE in the test app using the kvvfs. This obviates the changes made in [5c505ee8a7]. (check-in: 8fbda563d2 user: stephan tags: trunk)
13:31		Extra robustness in the code that causes cursors to return NULL when they are participating in an OUTER JOIN. (check-in: 672c2869ef user: drh tags: trunk)
11:48		For sqlite3.oo1.DB JavaScript classes, bypass execution of any on-open() SQL in SEE-capable builds because it would necessarily run before the client has an opportunity to provide their decryption key, which would leave the db handle in an unusable state and cause the ctor to throw. This currently affects only the OPFS VFSes. We may want to consider extending the ctor options object to optionally accept an SEE key and apply it when opening the db. (check-in: 5c505ee8a7 user: stephan tags: trunk)
00:42		Continuation of the fix at [8c0f69e0e4ae0a44]: If a viaCoroutine FROM clause term is participating in a RIGHT or FULL JOIN, we have to create an always-NULL pseudo-cursor for that term when processing the RIGHT join. dbsqlfuzz 6fd1ff3a64bef4a6c092e8d757548e95698b0df5. (check-in: e1040e51eb user: drh tags: trunk)
2024-04-21
23:35		Fix an indentation problem in debugging routine sqlite3ShowSrcList(). No changes to production code. (check-in: 5560df2726 user: drh tags: trunk)
2024-04-20
19:19		Slight performance improvement for the new code on this branch. (check-in: 500c67f134 user: dan tags: vector-in-fix)
15:14		Fix a problem where an expression like (a, b) IN (SELECT ...) might not use an index on (a, b) if the affinities and collation sequences of "a" and "b" are not identical. (check-in: 4d870fd8b5 user: dan tags: vector-in-fix)
2024-04-18
16:11		Correct handling of OUTER JOIN when on or the other operand is a subquery implemented using the VALUES-as-coroutine optimization. dbsqlfuzz bde3bf80aedf25afa56e2997a0545a314765d3f8. (check-in: 8c0f69e0e4 user: drh tags: trunk)
2024-04-17
19:48		Prevent tokenize-blobs from being used with non-contentless tables. Fix some other issues with the new code on this branch. (Leaf check-in: 6a640ea4d8 user: dan tags: fts5-tokenize-blob)
2024-04-16
14:23		Add some tests for the fts5 tokenize-blob functionality on this branch. (check-in: c2f9d1259c user: dan tags: fts5-tokenize-blob)
2024-04-15
20:43		The first assert() added in [0ebc65481f4a3e79] is not necessarily true in a corrupt database file. So add a term to make it true. (check-in: 6b21cccdee user: drh tags: trunk)
20:24		Add experimental way to specify an alternative tokenizer when writing to or querying an fts5 table. (check-in: 6c51c9c6a8 user: dan tags: fts5-tokenize-blob)

14:39		Merge the latest trunk enhancements into the wal2 branch. (Leaf check-in: 4a72acbc4b user: drh tags: wal2)
14:36		Merge the latest trunk enhancements into the begin-concurrent branch. (Leaf check-in: eedf6bed2a user: drh tags: begin-concurrent)
14:29		Merge from wrong branch. Bedrock should be updated from wal2, not from trunk. (Closed-Leaf check-in: 4c23cad98d user: drh tags: mistake)
14:21		Merge all 3.45.3 changes into the wal2-3.45 branch. (Leaf check-in: 2ccc018546 user: drh tags: wal2-3.45)

2024-04-12
18:46		If a build fails in testrunner.tcl, do not attempt to run the jobs that depend on that build. Instead, report those jobs as having been skipped. (check-in: b40580be71 user: drh tags: trunk)
16:52		Adjustment to EQP output in one test case. (check-in: 08dd2b927b user: drh tags: branch-3.45)

02:57		Mark the BTree cell overflow cache as invalid whenever the rowid goes invalid. (check-in: 74c9e19c92 user: drh tags: btree-ovfl-cache)
2024-04-11
19:09		Fix handling of the SQLITE_OMIT_WAL check in one place. Resolves [forum:87cc13302de160eb\|forum post 87cc13302de160eb]. (check-in: ce86d30d91 user: stephan tags: branch-3.45)
19:08		Fix handling of the SQLITE_OMIT_WAL check in one place. Resolves [forum:87cc13302de160eb\|forum post 87cc13302de160eb]. (check-in: 5dae6e6df4 user: stephan tags: trunk)
2024-04-10

14:07		Ignore CHECK constraints when qualifying the xfer optimization while running VACUUM. (check-in: bb6f990809 user: drh tags: branch-3.45)
13:57		The read-only CHECK-constraint optimization of [34ddf02d3d21151b] inhibits the xfer optimization for tables with CHECK constraints. However, the xfer optimization is required for correct operation of VACUUM INTO on tables that contain generated columns. Fix this by ignoring CHECK constraints when qualifying the xfer optimization while running VACUUM. Problem reported by [forum:/forumpost/3ec177d68fe7fa2c\|forum post 3ec177d68fe7fa2c]. (check-in: a6e26e7788 user: drh tags: trunk)

2024-04-07
18:55		Merge trunk testing enhancements into the pushdown-subquery branch. (check-in: 287ff24b26 user: drh tags: pushdown-subquery)
18:36		Omit all rowid-in-view restrictions from the fuzzinvariant.c test module as they are no longer necessary, as of the previous check-in. (check-in: 6431538f0b user: drh tags: trunk)
18:23		If SQLITE_ALLOW_ROWID_IN_VIEW is set to 2, then all rowids for views return a value of NULL. (check-in: 0a53dde214 user: drh tags: trunk)

14:13		Check-in a9657c87c53c1922 is wrong: the IndexedExpr.bMaybeNullRow flag is required for virtual columns if they are part of an outer join. Add a test case to prove it. (check-in: 083b0f7e77 user: drh tags: branch-3.44)
14:06		Fix obscure issues associated with SQLITE_ALLOW_ROWID_IN_VIEW and indexes on virtual columns in a RIGHT JOIN. (check-in: 4b3a253fc7 user: drh tags: branch-3.45)
13:56		Check-in [a9657c87c53c1922] is wrong: the IndexedExpr.bMaybeNullRow flag is required for virtual columns if they are part of an outer join. Add a test case (derived from dbsqlfuzz b9e65e2f110df998f1306571fae7af6c01e4d92b) to prove it. (check-in: 4484ec6d26 user: drh tags: trunk)

11:23		When compiling with SQLITE_ALLOW_ROWID_IN_VIEW, if the RETURNING clause of an UPDATE of a view specifies a rowid, then return NULL for the value of that rowid. dbsqlfuzz 7863696e9e5ec10b29bcf5ab2681cd6c82a78a4a. (check-in: c7896e8885 user: drh tags: trunk)
2024-04-04
22:53		Optimize sqlite3.oo1.DB.exec() for the rowMode='object' case to avoid converting the object property keys (column names) from native code to JS for each row. This speeds up large data sets considerably and addresses the report in [forum:3632183d2470617d\|forum post 3632183d2470617d]. (check-in: 8b41ef8690 user: stephan tags: trunk)
14:26		Add the "interstage-heuristic" that attempts to avoid wildly inefficient queries that use table scans instead of index lookups because the output row estimates are inaccurate. (check-in: 7bf49e2c54 user: drh tags: trunk)
13:36		Fix an ASAN problem in part of the test harness. No changes to SQLite itself. (check-in: 797cda7ddc user: drh tags: trunk)

15:52		Add comments (only, no code) to the JS sqlite3_config() bindings reminding us why SQLITE_CONFIG_ROWID_IN_VIEW is specifically not included. JNI does not need this treatment because it explicitly supports only a very small subset of config options. (check-in: 4fea396221 user: stephan tags: trunk)
11:46		Enhancements to testrunner.tcl: (1) Add the "--config CONFIGS" option, to that only configuration named on the comma-separated list CONFIGS are run.

11:04		Fix the SQLITE_ALLOW_ROWID_IN_VIEW bug-compatibility option so that it works again.

2024-03-19
23:01		Change the SQLITE_CONFIG_NO_ROWID_IN_VIEW configuration option to be just SQLITE_CONFIG_ROWID_IN_VIEW (without the "_NO_" in the middle) and give it the ability to turn the option on and off. Otherwise, it is difficult to test. (check-in: 5d412edc2e user: drh tags: rowid-in-view)
19:56		Return the error "ambiguous column name: rowid", instead of "no such column: rowid", when a "rowid" reference is ambiguous. (check-in: 0615bdae2d user: drh tags: rowid-in-view)

18:03		Remove unnecessary blank lines from build commands in the default Makefile.in. (check-in: 76fb3a908f user: drh tags: trunk)
18:00		Add the "VALUES-as-coroutine" optimization. Large VALUES clauses on an INSERT, for example, prepare and run in about half the time and with half the memory.

17:04		Extend the scope expr-is-constant for function to cover the IN-to-EQ optimization. (check-in: dae669245c user: drh tags: enhanced-expr-is-const)
14:27		Fix exprNodeIsConstantFunction() so that it returns WRC_Continue, not WRC_Abort, if the function really is constant. (check-in: d85dd4de2d user: dan tags: enhanced-expr-is-const)
13:18		Enhance the sqlite3ExprIsConstant() function so that it recognizes constant functions. So far the enhancement only applies to the multi-row VALUES clause, but it could possibly be applied in many other places. (check-in: c9e0488c6c user: drh tags: enhanced-expr-is-const)

12:59		Attempt to use the Dekker high-precision floating point algorithm in the ext/misc/totype.c extension. This check-in should have been derived from trunk, not the exp-values-clause2 branch. But that's ok, because both trunk and the branch are the same in all aspects that relate to this check-in and this check-in is just parking the proposed enhancement for future consideration - it is not a serious proposal at this point.

12:48		Enhancements to PRAGMA optimize and ANALYZE. Add the 0x10000 flag to PRAGMA optimize. ANALYZE now records zero-size partial indexes in the sqlite_stat1 table. PRAGMA optimize looks for both growth and shrinkage in table sizes, and uses tighter bounds (10x rather than 25x) to trigger a re-analyze. PRAGMA optimize automatically uses are reasonable analysis_limit to prevent excessive runtimes. (check-in: 63ef234e88 user: drh tags: trunk)

16:22		If a table has one or more rows and it has a partial index has zero rows, still make an entry in the sqlite_stat1 table for the partial index, so that we know that "PRAGMA optimize" does not need to redo the whole table. (check-in: e147b18991 user: drh tags: better-pragma-optimize)
13:50		Simplifications to PRAGMA optimize to make it easier to use. It always tries to ANALYZE unanalyzed indexes. The 0x10000 flag just makes it check for size changes in all tables. (check-in: 44ed7f4cd0 user: drh tags: better-pragma-optimize)
13:06		Change the 0x20000 bit (use analysis limit) to 0x10, meaning that this feature is on by default. The default analysis limit is changed to 2000 which is almost always sufficient for accurate analysis results. (check-in: 4abd47b591 user: drh tags: better-pragma-optimize)

21:09		Detect malformed nested JSONB earlier and stop rendering to avoid long delays. (check-in: 72f3e1d0ec user: drh tags: trunk)
20:36		When generated text JSON from JSONB, do not continue descending into nested structures after an error is seen. This avoids long loops and wait times. (check-in: 97666ec052 user: drh tags: trunk)
19:30		Consider an index for queries like "SELECT count(DISTINCT col) FROM ...", even if the index records are not smaller than the table records. (check-in: ad06868807 user: dan tags: trunk)
16:49		Avoid a potential buffer overread when handling corrupt json blobs. (check-in: ac402cc551 user: drh tags: branch-3.45)
15:30		Avoid a potential buffer overread when handling corrupt json blobs. (check-in: 738473dc0a user: dan tags: trunk)
12:58		When rendering JSONB back into text JSON, report an error if a zero-length integer or floating-point node is encountered. Otherwise, if the node occurs at the very end of the JSONB, the rendering logic might read one byte past the end of the initialized part of the BLOB byte array. OSSFuzz 66284. (check-in: 3ab08ac75d user: drh tags: branch-3.45)

20:17		Improvements to parser stack overflow testing. [forum:/forumpost/99e181b5bf\|Forum post 99e181b5bf]. (check-in: 556c43a937 user: drh tags: trunk)
12:47		Performance enhancements to the parser template. (check-in: 2db8b30acd user: drh tags: trunk)
12:25		Use an alternative memory allocator for parser stack space that includes a call to sqlite3FaultSim() to facilitate testing. (check-in: 7c36d560ff user: drh tags: trunk)
11:35		Allocate new parser stack space from the heap if needed, eliminating the possibility of a "parser stack overflow" error as long as heap memory is available. (check-in: d87a205477 user: drh tags: trunk)
02:21		Optimizations to ParseFinalize() to make up for the extra cleanup associated with the allocated parser stack. This branch now runs faster than trunk and is less than 300 bytes larger. (Closed-Leaf check-in: f7290db63c user: drh tags: growable-parser-stack)
01:35		Omit the "parser stack overflow" error message, since it no longer occurs. Replace it with an ordinary "out of memory". (check-in: 33f17ec248 user: drh tags: growable-parser-stack)
2024-01-26
20:57		Bug fixes in the function that expands the parser stack. (check-in: e91179fe84 user: drh tags: growable-parser-stack)

2024-01-23
21:10		Slight adjustment to test results for Windows in mmap1.test due to the previous check-in. (check-in: a8043eaed8 user: drh tags: branch-3.45)
21:10		Slight adjustment to test results for Windows in mmap1.test due to the previous check-in. (check-in: 5cf9ea9b1f user: drh tags: trunk)
16:21		In os_unix.c and os_win.c, do not allow xFetch() to return a pointer to a page buffer that is right at the end of the mapped region - if the database is corrupted in a specific way such a page buffer might be overread by several bytes. (check-in: 198a1daae0 user: drh tags: branch-3.44)
16:17		In os_unix.c and os_win.c, do not allow xFetch() to return a pointer to a page buffer that is right at the end of the mapped region - if the database is corrupted in a specific way such a page buffer might be overread by several bytes. (check-in: d131cab652 user: drh tags: branch-3.45)

13:58		Bump the version number to 3.45.1 (check-in: 54d34edb89 user: drh tags: branch-3.45)
13:53		When a JSON input is a blob, but it looks like valid JSON when cast to text, then accept it as valid JSON. This replicates a long-standing bug in the behavior of JSON routines, and thus avoids breaking legacy apps. (check-in: 4c2c1b97dc user: drh tags: branch-3.45)
13:51		When a JSON input is a blob, but it looks like valid JSON when cast to text, then accept it as valid JSON. This replicates a long-standing bug in the behavior of JSON routines, and thus avoids breaking legacy apps. [forum:/forumpost/012136abd5292b8d\|Forum thread 012136abd5292b8d]. (check-in: e5dc81d5c7 user: drh tags: trunk)
13:28		Fix typo in the tag-20240123-a in a comment. (Closed-Leaf check-in: 1f09541eb4 user: drh tags: blob-as-json)
13:21		If a BLOB looks like JSON when cast to text, then treat it as if it really were JSON. This replicates a long-standing bug in the JSON processing routines, and thereby avoids breaking legacy. (check-in: d79a37690c user: drh tags: blob-as-json)
12:51		Change the shell's --help flag to exit with code 0 instead of 1, per /forum and /chat discussions. (check-in: df563a1857 user: stephan tags: trunk)
11:20		Add extra checks for the validity of a numeric literal to sqlite3DequoteNumber(). (Closed-Leaf check-in: d57407ef59 user: dan tags: digit-separators)

15:26		Improved error message when a double-quoted string is used and it seems likely that the user wanted a single-quoted string literal. (check-in: 0a834bd811 user: drh tags: improved-dqs-error-msg, blob-as-json)
14:16		The -DSQLITE_JSON_BLOB_INPUT_BUG_COMPATIBLE compile-time option causes blob inputs to JSON functions that are not JSONB to be processed as if they where text, immulating historical bugging behavior which some applications have come to rely upon. See [forum:/forumpost/012136abd5292b8d\|forum thread 012136abd5292b8d] for discussion. (check-in: 6557222358 user: drh tags: blob-as-json)
14:01		Fix test script literal.test so that it works with SQLITE_OMIT_ALTER_TABLE builds. (check-in: 4dc00f5776 user: dan tags: trunk)
12:56		Fix userauth so that it works together with SQLITE_OMIT_SHARED_CACHE. ([forum:/forumpost/0bfc5888a384d430\|Forum post 0bfc5888a384d430]). However, also change to code to issue a deprecation warning whenever SQLITE_USER_AUTHENTICATION is used. (check-in: 249048b0cb user: drh tags: trunk)
12:30		Add a notice to the user-authentication documentation to say that the extension is deprecated and may disappear in the future. (check-in: fe6fc7b91a user: drh tags: trunk)

18:26		Simplifications to the strftime() logic. (check-in: aaa5a044d8 user: drh tags: trunk)
18:21		Fix a memory leak in new memdb1.test test cases that were added by [e638d5e408ea2e18]. No changes to SQLite itself. (check-in: bb2b7a658e user: drh tags: trunk)

16:29		Rig sqlite3_serialize() so that it will initialize a previously uninitialized database prior to serializing it, so that it does not have a zero-byte size and does not return NULL (except for OOM). [forum:/forumpost/498777780e16880a\|Forum thread 498777780e16880a]. (check-in: e638d5e408 user: drh tags: trunk)
16:18		Allow "_" characters to appear following any digit in an integer or real SQL literal. (check-in: 401650aacc user: dan tags: digit-separators)
15:13		When doing a text-affinity comparison between two values where one or both have both a text and a numeric type, make sure the numeric type does not confuse the answer. This is a deeper fix to the problem observed by [forum:/forumpost/3776b48e71\|forum pose 3776b48e71]. The problem bisects to [25f2246be404f38b] on 2014-08-24, prior to version 3.8.7. (check-in: 709841f88c user: drh tags: trunk)
13:18		Ensure that the replace() SQL function always returns a TEXT value even when its first argument is numeric and its second argument is an empty string. Fix for the issue reported by [forum:/forumpost/3776b48e71\|forum post 3776b48e71]. (check-in: 01868ebcd2 user: drh tags: trunk)

12:00		Fix the version number in the TEA configure script. This should have been changed by [1481baf3d55effcc] three check-ins ago. It is unclear how testing missed this. (check-in: eaf2cf73fc user: drh tags: trunk)
00:31		Implement a new algorithm for computing ISO week values in strftime() based on the idea (from [forum:3681cb1bcd\|Nuno Cruces]) of shifting the date being tested to the Thursday of the same week. (check-in: b06ab46a9e user: drh tags: trunk)

12:56		Remove some dead JS code. Minor doc cleanups. (check-in: bf23cf2049 user: stephan tags: wasm-post-3.45)
12:31		Split the JS vfs/vtab helper code into discreet units as a step towards a build which optionally elides those pieces. This is an internal restructuring change and does not affect the API. (check-in: ede945fd23 user: stephan tags: wasm-post-3.45)
2024-01-10
20:13		Fix a few compiler gripes. Update 2024-04-16: Closed, since the solution to Windows console I/O already on trunk is better. (Closed-Leaf check-in: 2e74a938f7 user: larrybr tags: win-dupe-crt-fio)
05:52		For CLI shell and other utilities, optionally avoid C runtime file I/O on Windows in favor of WIN32 calls, while nominally preserving FILE* API interfaces. (a WIP, awaiting build and testing) (check-in: 6be68be179 user: larrybr tags: win-dupe-crt-fio)

07:52		Make explicit which JS APIs are for internal use only by moving the JS-bound internal-use-only functions out of client-visible reach and renaming the WASM-exported ones from sqlite3_wasm... to sqlite3__wasm... (with two underscores). These have always been documented as internal-use-only, so this is not a breaking change except for clients which have ignored the docs. (check-in: 0eddc20f37 user: stephan tags: wasm-post-3.45)

23:28		Back out [99d11e6d0ae6] (enabling of STAT4 in WASM/JNI), per /chat discussion. (check-in: cd7929ee2e user: stephan tags: trunk)
19:20		New logic to avoid using indexes that ANALYZE has identified as of little practical use. Also a performance optimization in ANALYZE. (check-in: bcac937526 user: drh tags: trunk)
17:58		Remove some unnecessary computations from ANALYZE so that ANALYZE runs with fewer CPU cycles. These changes were spotted while working on the nearby enhanced-stat1 branch. So even if enhanced-stat1 is abandoned, that effort put into it will not have been in vain. (Closed-Leaf check-in: 5527e8c4ab user: drh tags: avoid-low-quality-indexes)
17:48		Extra steps taken to avoid using low-quality indexes in a query plan. This branch accomplishes the same end as the nearby enhanced-stat1 branch, but with much less change and hence less risk. (check-in: c030e64626 user: drh tags: avoid-low-quality-indexes)
15:49		Improved defenses against deliberately corrupted sqlite_stat1 tables. (Closed-Leaf check-in: ee34db31a0 user: drh tags: enhanced-stat1)
15:35		Fix a harmless compiler warning. (check-in: b5aa1aea38 user: drh tags: enhanced-stat1)
14:13		Omit the uneven=N argument in sqlite_stat1 and replace it with var=N1,N2,... so that the variation in each column is reported separately. Omit the "slow" argument from sqlite_stat1, computing that flag internally. PRAGMA stats is enhanced with a new column "est" that shows the aiRowLogEst array for each index after it has been modified by "var=..." and also the "slow" flag. (check-in: 4a8fc17365 user: drh tags: enhanced-stat1)
06:58		JNI: move the ByteBuffer-using APIs from public to package visibility for the time being because they have UB-inducing possibilities which need to be worked out. Update test code to account for a change in custom FTS5 columntext() impls. (check-in: dc501275fc user: stephan tags: trunk)
05:58		WASM: various build cleanups and add initial infrastructure for a build which elides the oo1 API and its dependents (worker1 and promiser). Sidebar: an attempt was made to move generation of the build rules to an external script, but the mixed-mode make/script was even less legible than the $(eval) indirection going on in the makefile. (check-in: 563d313163 user: stephan tags: trunk)
2023-12-31
20:04		Better comments. Slight tuning of parameters. (check-in: 1cc32eccda user: drh tags: enhanced-stat1)
12:38		Ensure that all elements of aiRowLogEst[] have been initialized even if the stat entry is truncated. (check-in: c216921b11 user: drh tags: enhanced-stat1)
04:01		Use SQLITE_ENABLE_STAT4 in both the WASM and JNI builds. (check-in: 99d11e6d0a user: stephan tags: trunk)
2023-12-30
22:00		In sqlite_stat1, revert the number of rows to the average, not adjusted for the maximum. Instead add "uneven=NNN" where NNN is a multiplier to apply to the average to get the maximum. "uneven" is only reported if NNN is 10 or more. Also add the "slow" argument is the maximum number of rows reported by a full equality match is so large that a table scan seems likely to be faster. (check-in: 41773fa760 user: drh tags: enhanced-stat1)
15:07		Omit the "noquery" argument in sqlite_stat1. Instead, add the "uneven" argument for indexes that have an uneven distribution of values. Modify the query planner to avoid doing equality look-ups on uneven indexes. (check-in: 0ec4b880bb user: drh tags: enhanced-stat1)
2023-12-29
21:07		Revise the "noquery" decision algorithm again. The index now must select more than 150 rows on average, and the number of rows select must be enough that it seems faster to do a full scan of the associated table. (check-in: f516ef80a0 user: drh tags: enhanced-stat1)
20:31		Fix an issue in the "noquery" decision in the previous check-in. Also add comments explaining the algorithm. (check-in: 6aaa65adfc user: drh tags: enhanced-stat1)
20:08		Add the "noquery" argument as an option for the stat column of sqlite_stat1. If set, then the index will not be used to optimize a query. Enhance ANALYZE to set that argument on very low selectivity indexes. (check-in: e514d3fa83 user: drh tags: enhanced-stat1)
19:03		Attempt to improve the ANALYZE command so that it does a better job of detecting lopsided indexes and makes appropriate changes to the sqlite_stat1 table. (check-in: 4b70b94616 user: drh tags: enhanced-stat1)
04:29		Minor doc touchup in the JS bits. (check-in: 8d2120c354 user: stephan tags: trunk)
2023-12-28
21:02		Enable SQLITE_DIRECT_OVERFLOW_READ unless it is specifically disabled using the -DSQLITE_DIRECT_OVERFLOW_READ=0 compile-time option. (check-in: 630604a4e6 user: drh tags: trunk)
20:54		Update fts5origintext4.test to work with SQLITE_DIRECT_OVERFLOW_READ. (check-in: 15ed002aed user: dan tags: trunk)
19:18		Performance improvement by unwinding a loop in jsonAppendString(). (check-in: 190ab3c084 user: drh tags: trunk)

16:21		Enhance the (undocumented, debug-only) json_parse() SQL function so that it returns the text rendering of the JSONB parse of the input, rather than printing the rendering on stdout. (check-in: 056de8d551 user: drh tags: trunk)
14:07		Merge the latest trunk changes into the reuse-schema branch. (check-in: 3d1b0403d6 user: drh tags: reuse-schema)
14:01		Merge the latest trunk changes into the bedrock branch. (check-in: 5a17b972ed user: drh tags: bedrock)
13:44		Merge the latest trunk enhancements into the wal2 branch. (check-in: 1f592dd32d user: drh tags: wal2)
13:40		Merge recent trunk enhancements into the begin-concurrrent branch. (check-in: b3a2adfda7 user: drh tags: begin-concurrent)
2023-12-27
16:24		Fix a problem in the shell tool (not library) causing an out-of-bounds write if an ".open" command failed, then the user pressed ctrl-c to interrupt a query running on the substitute in-memory database. (check-in: 026618b9e3 user: dan tags: trunk)
2023-12-26
15:52		Ensure that the xColumnText(), xQueryPhrase() and xPhraseFirstColumn() APIs all return SQLITE_RANGE if they are passed a bad column or phrase number. (check-in: 1a8a9b1c89 user: dan tags: trunk)
13:20		Improved handling of malformed unicode within JSON strings. (check-in: e252bdf5f5 user: drh tags: trunk)
2023-12-24

11:31		Add debugging output routines sqlite3ShowWhereLoop(X) and sqlite3ShowWhereLoopList(X) that can be invoked from a debugger to show a summary of the content of a single WhereLoop object or a list of WhereLoop objects. No change in release builds. (check-in: 5db30bcc33 user: drh tags: trunk)
2023-12-22
21:22		Change parameters on a debugging function to include "const". (check-in: 94c3e1110c user: drh tags: trunk)

15:54		Back out an incorrect change to the sqlite3ExprCompareSkip() function that was added way back on 2019-08-22 for [44578865fa7baf97\|check-in 44578865fa7ba] and which was only today discovered to be incorrect by [forum:/forumpost/45ec3d9788\|forum post 45ec3d9788]. (check-in: f5b3eb0fc8 user: drh tags: trunk)
13:59		Arrange to not compile unused console I/O function. (check-in: 184a0cd2e8 user: larrybr tags: branch-3.44)
13:12		Convert an assert in OP_VCheck into a branch that aborts the opcode, as this can happen on some very obscure conditions, as discovered by dbsqlfuzz. (check-in: 0d5f68717c user: drh tags: branch-3.44)

2023-11-19
17:33		Fix test 5.0 in shell1.test for Windows. (A double-quote wrapped single-quote needs no further treatment to be recognized as a single single-quote.) (check-in: aaa73400c4 user: larrybr tags: branch-3.44)
2023-11-18

17:20		When ENABLE_SETLK is defined, avoid ever blocking on the lock mutex in os_unix.c when requesting an exclusive lock. (check-in: eb36d475e9 user: dan tags: trunk)
12:06		Adjust an assert() in fts5WritePoslistData() so that it only applies if there have been no prior errors. dbsqlfuzz 25dca9b2568f67dc78a0e32ff280133fe71994bd. (check-in: 257cdbab90 user: drh tags: trunk)
11:23		Another assertion fault fix, similar to [a9443dbfbe25e588]. dbsqlfuzz 2d9af4e94aca188e0092900eec711401c5d51687. (check-in: 3afaeac56d user: drh tags: trunk)
2023-11-17
19:01		When SQLITE_ENABLE_SETLK_TIMEOUT is defined, use a separate mutex in os_unix.c for each shm locking slot. (check-in: 64691df980 user: dan tags: trunk)
17:55		Add the new "run-fuzzcheck" target on the autoconf unix makefile. Requires that FUZZDB be set to the name of the fuzz-data database file. (check-in: 8fa3915dbf user: drh tags: trunk)
17:25		Add an assert() to prove the sqlite3_prepare() always either returns SQLITE_OK or else leaves *ppStmt set to NULL. See [forum:/forumpost/70bb8576c6c084c2\|forum post 70bb8576c6c084c2]. (check-in: feadd40242 user: drh tags: trunk)
17:10		When SQLITE_ENABLE_SETLK_TIMEOUT is defined, use a separate mutex in os_unix.c for each shm locking slot. (Closed-Leaf check-in: 4098df9652 user: dan tags: unix-setlk-timeout-mutexes)

2023-11-16
21:11		When querying a tokendata=1 fts5 table, do not use a prefix cursor for the case where the term has only one variant. (check-in: d711c96ba8 user: dan tags: fts5-token-data)
20:50		Cherrypick changes to simplify and make more rational how console I/O package features are selected. (Leaf check-in: b20c9f1785 user: larrybr tags: consio-3.44)
18:31		Simplify and make more rational how console I/O package features are selected. (Motivated by Fiddle and other command-line utilities to soon use the package.) No substantive code-execution changes. (check-in: 1cde05877b user: larrybr tags: console-io-lib)
2023-11-15
20:32		Both json_remove() jsonb_remove() work on pure JSONB as long as the input is JSONB. (check-in: 68d551730b user: drh tags: jsonb)
19:21		Some simple test cases for JSONB direct remove. (check-in: 8cb4d2cbfc user: drh tags: jsonb)
19:19		Changes so that if SQLITE_ENABLE_SETLK_TIMEOUT is defined as 2 instead of 1, all blocking locks are taken for a single millisecond and the default busy-handler invoked as normal. (check-in: 79e24ec3dd user: dan tags: trunk)
18:55		jsonb_remove() now works without having to use a JsonNode parse, assuming that the input is JSONB. (check-in: 5207679e92 user: drh tags: jsonb)
18:47		The jsonb_remove() routine now appears to be working. (Closed-Leaf check-in: e76d48137e user: drh tags: jsonb-remove)
16:54		Get Fiddle build to succeed. (It runs, too, but not from changes here.) (check-in: 957ebaa2be user: larrybr tags: consio-3.44)
16:10		Work toward getting jsonb_remove() to work directly on JSONB blobs. (check-in: a79ff8e58f user: drh tags: jsonb-remove)
15:20		Changes to console I/O for Fiddle build, to always defer to C library (as before.) A WIP, pending testing with Fiddle build. (check-in: 45b8061e75 user: larrybr tags: consio-3.44)
14:09		Improvements to the description of sqlite3_errmsg() and sqlite3_errstr(). (check-in: fe5cc4169c user: drh tags: trunk)
13:23		Merge all the latest enhancements and fixes from trunk into the jsonb branch. (check-in: ba91408f4c user: drh tags: jsonb)
11:45		Add implementation of xInstToken() API. (check-in: a34b26fe7f user: dan tags: fts5-token-data)
11:31		Fix an exception misuse in test-opfs-vfs.js. (check-in: 9264955e6e user: stephan tags: trunk)
08:59		JNI: add more wrapper1 Sqlite.Blob tests. (check-in: d63f6e1ffd user: stephan tags: trunk)
08:29		JNI: clear out the sqlite3_context native pointer after calling UDF callbacks which do not have an argv (as was already done for those which have an argv). Add related tests and code commentary. (check-in: 138f40543b user: stephan tags: trunk)
06:28		JNI doc updates. (check-in: 1b1f36a206 user: stephan tags: trunk)
06:10		JNI: add the @Experimental annotation and mark all java.nio.ByteBuffer-related methods with it. (check-in: 0f4b223102 user: stephan tags: trunk)
05:08		JNI test code cleanups. (check-in: 09142ac143 user: stephan tags: trunk)
04:55		JNI: add CONFIG_LOG and CONFIG_SQLLOG support to wrapper1. Code-adjacent cleanups. (check-in: 83c49b9e71 user: stephan tags: trunk)
03:02		JNI: apply an internal level of API indirection to avoid having to work with massively-mangled names for the various sqlite3_config() overloads. (check-in: 24f20663b1 user: stephan tags: trunk)
2023-11-14
16:53		Add NEVER() to a branch made unreachable by [6f9eed826f5b3d1c]. (check-in: 26dcaa34e3 user: drh tags: trunk)
14:59		JNI: reimplement Tester2.execSql() using the high-level API. (check-in: 3a69679e41 user: stephan tags: trunk)
14:50		Fix another obscure problem with nested aggregates. dbsqlfuzz 04408efc51. This might be a better fix than the one at [4a587c3492faa994]. (check-in: 6f9eed826f user: dan tags: trunk)
14:38		JNI: add Sqlite.Stmt.step(boolean) overload which returns the result code of sqlite3_step() unless passed true, in which case it throws for any result other than ROW or DONE. The intent is to simplify handling of LOCKED and BUSY errors. (check-in: f4f1cc201a user: stephan tags: trunk)
13:51		Extra PRAGMA vdbe_addoptrace output showing when OP_Column gets translated into OP_Copy due to using a coroutine instead of a cursor. (check-in: eba180e779 user: drh tags: trunk)
05:33		JNI: use ByteBuffer.limit() instead of ByteBuffer.capacity() when figuring out where the logical end of a ByteBuffer is, for reasons explained at length in new code comments. This is unfortunately slower but is the correct way to do it. (check-in: 51539419ed user: stephan tags: trunk)
04:59		JNI: add sqlite3_blob_read_nio_buffer() and iron out the blob/ByteBuffer interface somewhat. (check-in: 7df317b448 user: stephan tags: trunk)
03:31		Cherry-pick some assert()s to cover misuse of Put() from 500+ shell.c callers. (check-in: c1a53c28a4 user: larrybr tags: consio-3.44)
03:24		Add a few asserts into Put() functions to catch calls that might cause an address fault. (check-in: 2341f9b6a4 user: larrybr tags: console-io-lib)
02:43		JNI: change sqlite3_prepare_multi()'s exception-handling semantics to be more C-like and, to support that, add the package-private sqlite3_jni_db_error() method to set the db error state from package-level Java code. (check-in: 46656b3543 user: stephan tags: trunk)
01:33		JNI: add sqlite3_blob_write() overload which accepts a java.nio.ByteBuffer. Cleanups in adjacent code. (check-in: ca32af8542 user: stephan tags: trunk)
2023-11-13
23:11		JNI: add sqlite3_column_nio_buffer() and sqlite3_value_nio_buffer() using an only-slightly roundabout approach to creating properly-sized ByteBuffer objects. (check-in: efbc82b218 user: stephan tags: trunk)
18:35		JNI: add sqlite3_result_nio_buffer() and tests. Discover that we cannot create sensible sqlite3_column_nio_buffer() or sqlite3_value_nio_buffer() counterparts because of ByteBuffer interface limitations. (check-in: 44b4df01ff user: stephan tags: trunk)
17:45		Manual merge of branch-3.44 with 3 sources affected/created by console-io-lib changes. (check-in: 18ebcf117a user: larrybr tags: consio-3.44)
17:26		Mistaken creation by a Fossil expert-to-be-maybe. (Leaf check-in: 2e3e98a4a7 user: larrybr tags: mistake)
15:59		Cure many warnings from gcc, clang and CL.exe. (check-in: 29ea2a3aad user: larrybr tags: console-io-lib)
14:58		JNI: add sqlite3_bind_nio_buffer() and initial tests for binding ByteBuffer objects as blobs on JVMs which have JNI support for nio buffers. (check-in: b10ce1ef82 user: stephan tags: trunk)
14:29		Add new fts5 API xQueryToken(). (check-in: 828566392b user: dan tags: fts5-token-data)
13:01		Fix var-intro after executable code departure from old C. (check-in: 08996f4fd5 user: larrybr tags: console-io-lib)
12:53		Slight cleanup of length-limited strpbrk() replacement, and eliminate strpbrk() call. (check-in: 97e2c9621e user: larrybr tags: console-io-lib)
12:05		Remove an incorrect ALWAYS() and NEVER(). (check-in: 94f6209386 user: drh tags: branch-3.44)
05:24		Enhance console_io to permit emits limited in various ways, such as valid UTF-8, upto control chars, or with counted limits, all getting away from 0-termination as the sole limit. In CLI, use this capability to avoid certain emit-chars-singly procedures that were breaking up UTF-8 characters. This fixes broken json mode output (on Windows) and (maybe) C-literal-like emits. (check-in: 906c5c4082 user: larrybr tags: console-io-lib)
2023-11-12
19:57		Add sqlite3_x86.exe unversioned binary. (check-in: a731cdddbb user: larrybr tags: console-io-lib)
03:58		Use setOutputStream() to designate implicit output for oput{z,f}() emit functions, and use them extensively. (check-in: 7850fb98a1 user: larrybr tags: console-io-lib)
00:43		Write BOM without fwrite(), using sputz() so that if it goes to the console, it is translated "properly". (check-in: 06ef96a823 user: larrybr tags: console-io-lib)
2023-11-11
22:53		Remove SHELL_LEGACY_CONSOLE_IO PP symbol and code it made active. (It is in the repo if ever needed/wanted, but it is just inferior or dead code now.) (check-in: 27c5bf6563 user: larrybr tags: console-io-lib)
20:46		Complete shell transition to using {f,o,e}put{f,z}() emit functions. (check-in: 923c6b8b3a user: larrybr tags: console-io-lib)
14:50		JNI wrapper1: when checking for an out-of-bounds statement column index, perform the is-statement-finalized check before the range check so that the former exception trumps the latter. (check-in: 0832f9a8e9 user: stephan tags: trunk)
14:43		Do not cache a statement's column count in the JNI wrapper1 API because an ALTER TABLE via another statement may invalidate it, as reported in [forum:6d80efd58d4591c7\|forum post 6d80efd58d4591c7]. (check-in: a6ab88e9a6 user: stephan tags: trunk)
13:09		Fix malf with redirected input due to bad assumption that stdin is a console in the fgets() replacement. (check-in: 79d1f2c101 user: larrybr tags: console-io-lib)
06:20		Pervasive changes to console_io.{c,h} in support of simplifying ubiquitous emit ops in shell, and to get better control of console streams that might be opened only via .read or .output commands. Changes to shell to use {s,o,e}put{f,z}(...) calls for initial testing, but this check-in has few such conversions so that most will be in a separate check-in. Many renames to better follow recent coding convention. This code seems to be working, but has not been tested on difficult platforms or with multiple console hosts yet. So it is a WIP. (check-in: 14762a004c user: larrybr tags: console-io-lib)

18:59		Merge recent trunk enhancements and fixes into the jsonb branch. (check-in: 091a5f058d user: drh tags: jsonb)
17:49		Ensure 8-byte alignment of data structues in sqlite3_database_file_object(). This should have appeared on trunk originally and then be cherry-picked onto the branch. Oh well.... (check-in: ac39800bb2 user: drh tags: trunk)
16:29		Remove a NEVER() from whereAddIndexedExpr() that is reachable if there is an unknown indexed function in the schema. (check-in: a976b7208f user: drh tags: trunk)

17:53		Expose SQLITE_RESULT_SUBTYPE to wasm. (check-in: 6d2fe9848b user: stephan tags: trunk)
17:42		Add the SQLITE_RESULT_SUBTYPE flag for application-defined functions. Add the -DSQLITE_STRICT_SUBTYPE=1 compile-time option that raises an error if any function invokes sqlite3_result_subtype() without the SQLITE_RESULT_SUBTYPE flag. SQLITE_RESULT_SUBTYPE prevents an indexed value of that function from being used to replace an equivalent expression, since the indexed expression does not carry the subtype. (check-in: 65a9cfc466 user: drh tags: branch-3.44)
17:36		Add the SQLITE_RESULT_SUBTYPE flag for application-defined functions. Add the -DSQLITE_STRICT_SUBTYPE=1 compile-time option that raises an error if any function invokes sqlite3_result_subtype() without the SQLITE_RESULT_SUBTYPE flag. SQLITE_RESULT_SUBTYPE prevents an indexed value of that function from being used to replace an equivalent expression, since the indexed expression does not carry the subtype.

16:52		Futher documentation refinements. (check-in: 311c2eba93 user: drh tags: func-rw-subtype)
15:01		Fixes: (1) In the ->> function, instead of setting a subtype and clearing it, do not set it in the first place, as doing the set would trigger an error under SQLITE_STRICT_SUBTYPE. (2) Allow the SQLITE_STRICT_SUBTYPE through the property filter on sqlite3_create_function(). (check-in: 6195468b14 user: drh tags: func-rw-subtype)
13:00		A .class file build dependencies fix in the JNI build. (check-in: 8cc3291516 user: stephan tags: trunk)
12:58		Add the SQLITE_STRICT_SUBTYPE compile-time option. This change reveals that the current SQLITE_RESULT_SUBTYPE design does not work unless we tag the ->> operator with SQLITE_RESULT_SUBTYPE. But that will disable an important optimization. (check-in: e98a9a65dd user: drh tags: func-rw-subtype)
12:48		Add some notes about the JNI pointer-passing approach and convert a couple of potential NullPointerExceptions into appropriate C result codes. Clarify that invocation of undefined behaviour from the Java API does not (due to the addition of defensive code) mean the same thing as it does in C (e.g. no NULL pointer dereferences). (check-in: 19c4778f45 user: stephan tags: trunk)
12:17		Do not replace expressions that return subtypes with values taken from an index. (check-in: a35d13db09 user: drh tags: func-rw-subtype)
12:08		Omit the new SQLITE_VALUE_SUBTYPE name. Stay with legacy SQLTIE_SUBTYPE.

00:45		Suppress harmless UBSAN warnings about memory overflow in OP_AddImm. The exact same machine code is generated by GCC. (check-in: b0594383b9 user: drh tags: trunk)
00:12		Changes a no-op call to freeP4() into an assert(). (check-in: 32a7b1bd4d user: drh tags: trunk)
2023-11-07
20:56		Add -DSQLITE_ENABLE_SETLK_TIMEOUT=1 to a release-test configuration. (check-in: cd3e38fb0f user: dan tags: trunk)
20:11		Fix an assert() that could fail within calls to sqlite3_snapshot_open() in SQLITE_ENABLE_SETLK_TIMEOUT builds. (check-in: 84634bc268 user: dan tags: trunk)

19:30		Refactor MBCS/UTF-8 translation to avoid extra allocations, supporting non-formatted (faster) output. Some code cleanup. Wrap .system/.shell command exection with restoration of startup console mode and renewing mode setup. Changes to make legacy MBCS build work better (than legacy did, even with --no-utf8.) (check-in: d5e88fcde5 user: larrybr tags: console-io-lib)
19:15		Update the documentation to the sqlite3_set_auxdata() and sqlite3_get_auxdata() routines to make it clear that they do not work as one might expect when they are called during query planning, instead of during query execution. The JSON routines misuse those interfaces, so add a special flag to JSON routines that prevents them from being invoked during query planning. (check-in: 36259009c5 user: drh tags: branch-3.44)
19:03		Update the documentation to the sqlite3_set_auxdata() and sqlite3_get_auxdata() routines to make it clear that they do not work as one might expect when they are called during query planning, instead of during query execution. The JSON routines misuse those interfaces, so add a special flag to JSON routines that prevents them from being invoked during query planning.

17:15		JNI: during static init record whether the current JVM supports JNI-level access to java.nio.ByteBuffer raw memory, and add sqlite3_jni_supports_nio() to query that. (check-in: fb8dbb77a4 user: stephan tags: trunk)
15:56		Add Sqlite.prepareMulti() to JNI wrapper1, for preparing multiple statements from a single input. (check-in: e4670d68b5 user: stephan tags: trunk)
13:44		Diverse minor cleanups in the JNI pieces. (check-in: 35233dd900 user: stephan tags: trunk)

02:41		Get dependencies into make recipes. Get legacy console I/O (-DSHELL_LEGACY_CONSOLE_IO) working. Due to movement of MBCS/UTF-8 translation into traditional stream I/O simulacra, the input translation does not happen the same way. (It works the same, but fails differently and a bit better.) Added printf() and fputs() look-alikes, and made CLI use them. (check-in: 1721dc6a43 user: larrybr tags: console-io-lib)
2023-11-06
21:57		Add -DSQLITE_ENABLE_COLUMN_METADATA to the JNI build, as per [forum:9205518c0568fdf0\|forum post 9205518c0568fdf0]. Add tests for the functions that flag enables so that the build will fail if that flag is missing. (check-in: 7a63b5b65a user: stephan tags: trunk)

19:08		Update the srctree-check.tcl script and child script so that they can be run on a read-only source tree and so that if any inconsistencies are found, the script returns a non-zero exit code and thus halts the build. (check-in: a0cc7e8117 user: drh tags: branch-3.44)
19:01		Fix an fts5 problem where a transaction consisting of (a) a DELETE on rowid X, (b) a prefix query, and (c) an INSERT on rowid X, could corrupt the index. (check-in: 34af510a56 user: drh tags: branch-3.44)

13:24		Add an fputs() equivalent to console I/O lib, and use in CLI. (check-in: d661f90724 user: larrybr tags: console-io-lib)
03:09		Cause CLI to use console_io library. (check-in: bf66a7c1d3 user: larrybr tags: console-io-lib)
00:15		Make MSVC accept it, too. (Cannot use static const int as part of a constant expression?) (check-in: bb278d2496 user: larrybr tags: console-io-lib)
2023-11-05
23:55		Make it buildable. Pull test program from testee. Zap stray fprintf(). (check-in: 2b850aca1e user: larrybr tags: console-io-lib)
19:42		Input working. No line-editor provisions yet. (WIP, but suitable for testing.) (check-in: e8568b1d92 user: larrybr tags: console-io-lib)
04:20		Add incremental blob I/O support to JNI wrapper1. (check-in: 7f1c76fe93 user: stephan tags: trunk)
03:37		JNI wrapper1 normalizeSql() now throws UnsupportedOperationException, instead of returning null, if built without SQLITE_ENABLE_NORMALIZE. Remove SQLITE_PREPARE_NORMALIZE from the JNI interface because it's a legacy no-op. (check-in: d081a12669 user: stephan tags: trunk)
01:55		Add authorizer support to JNI wrapper1. (check-in: 773f987386 user: stephan tags: trunk)
01:39		Add progress-handler support to JNI wrapper1. Correct the return type of the extended_result_codes() JNI binding and expose it to wrapper1. (check-in: 6c0acfdce2 user: stephan tags: trunk)
01:21		Setup, takedown, mode set and output working. No input yet. (WIP) (check-in: dfea85be1f user: larrybr tags: console-io-lib)

00:48		Add commit/rollback hook support to JNI wrapper1. (check-in: ff3d44fe42 user: stephan tags: trunk)
00:02		Add busy-handler support to JNI wrapper1. (check-in: dcf579ab2d user: stephan tags: trunk)
2023-11-04
23:37		Bind collation and collation-needed to JNI wrapper1 and correct the callback return type for collation-needed callbacks in the lower-level JNI binding. (check-in: 0f67314068 user: stephan tags: trunk)
22:47		Wrap the sqlite3_backup API in the JNI wrapper1 API. (check-in: 3ee6cc29d2 user: stephan tags: trunk)
21:51		Reimplement auto-extensions in Java for use with the JNI wrapper1 API. (check-in: 14ed4c6453 user: stephan tags: trunk)
21:44		Ensure that the YYYY-MM-DD input to date and time functions has been normalized prior to returning a result. [forum:/forumpost/6bb476897e\|Forum post 6bb476897e]. (check-in: b692eb8ccb user: drh tags: trunk)

12:53		Bind the trace API to the JNI wrapper1 API and add a way to map the native-level db/stmt types to their high-level counterparts (required for translating callbacks such as tracers). (check-in: 702910e0d1 user: stephan tags: trunk)
02:22		Define interface between project command-line apps and a console I/O "library". (check-in: 64abef8314 user: larrybr tags: console-io-lib)
2023-11-03
18:45		Back out the ALWAYS inserted late yesterday. The fuzzer discovered a counter-example. (check-in: 570635575c user: drh tags: trunk)
17:20		Fix a case where adjacent tokens are handled incorrectly by the fts5 snippet() function. (check-in: 8f5e9c192f user: dan tags: trunk)
13:00		Wrap more of the stmt API behind the JNI wrapper1 API. (check-in: 8fea23dc3a user: stephan tags: trunk)
12:09		Enhance the JSONB lookup routine with logic to apply edits. The new logic is currently unused and hence untested but does not create any regressions. (check-in: b12110276f user: drh tags: jsonb)
11:53		Bind the sqlite3_keyword_...() and sqlite3_compileoption_...() family of functions to the JNI wrapper1 API. (check-in: b27242414d user: stephan tags: trunk)
11:41		Update the tool/srctree-check.tcl script so that it verifies that autoconf has been run following edits to VERSION. (check-in: 52ab3deba4 user: drh tags: trunk)
11:35		Merge all the latest trunk fixes and enhancements into the jsonb branch. (check-in: b089bf4637 user: drh tags: jsonb)

2023-11-02
22:39		Mark a branch made always-true by the penultimate check-in with ALWAYS(). (check-in: 268b5984a4 user: drh tags: trunk)
22:11		In the previous check-in, use a u32 instead of an int, to make it easier to prove that the integer will never overflow. (check-in: 51002079e0 user: drh tags: trunk)
21:02		Fix a spurious "misuse of aggregate function" error that could occur when an aggregate function was used within the FROM clause of a sub-select of the select that owns the aggregate. e.g. "SELECT (SELECT x FROM (SELECT sum(t1.a) AS x)) FROM t1". [forum:/forumpost/c9970a37ed \| Forum post c9970a37ed]. (check-in: 4470f657d2 user: dan tags: trunk)

13:10		One more tweak to tool/srctree-check.tcl so that a complete build can be accomplished from a read-only source tree. (check-in: cba9f0601c user: drh tags: trunk)
12:05		Update the srctree-check.tcl script and child script so that they can be run on a read-only source tree and so that if any inconsistencies are found, the script returns a non-zero exit code and thus halts the build. (check-in: 58eb5440d7 user: drh tags: trunk)
11:14		Update the version number to 3.44.1 (check-in: 34f23c3d0d user: drh tags: branch-3.44)
11:08		CLI to compile with older MSVC compiler. (check-in: c8bf4f7a6a user: drh tags: branch-3.44)

19:03		Add a cast to i64 for an integer in an sqlite3OsWrite() offset calculation. The cast is not strictly necessary, but it helps human readers see that the code is correct. (check-in: 7564ff1ba2 user: drh tags: trunk)
18:48		Fix another comment typo. No code changes. (check-in: 3203256c02 user: drh tags: trunk)

19:55		Simplify code slightly. Improve comments on added code and its use. (check-in: 046c842966 user: larrybr tags: win-utf8-io-split)
16:26		Properly close a handle. Use a putatively effective runtime test for UTF-8 console I/O capability. (This makes the version test useful mainly for avoiding a warning that UTF-8 console I/O could not be setup.) (check-in: dc91eb9172 user: larrybr tags: win-utf8-io-split)
00:24		Condition default UTF-8 console I/O for Windows builds on OS version 10 or more. This is to accomodate an IsValidCodePage() API which may happily report CP_UTF8 as a valid code page when the stock console cannot, in fact, do UTF-8 I/O.

16:19		Limit the range of integer unix timestamps in date4.test, since some systems (RaspberryPI) cannot deal with timestamp values that exceed pow(2,31). (check-in: 765290663b user: drh tags: trunk)
11:53		Update documentation for sqlite3_errmsg() to try to make it clear that if the schema of a database contains table names or similar with invalid UTF, then the error message generated by SQLite might also contain invalid UTF. No changes to code. (check-in: 33ba13c7c4 user: drh tags: trunk)
11:40		Since SQLite considers NaN to be like NULL and NULL sorts before any integer, make sure the sqlite3IntFloatCompare() routine reports that the integer argument is larger if the floating-point argument is NaN. (check-in: de1cf31a34 user: drh tags: trunk)
04:11		Remove the SQLITE_MAX_ALLOCATION_SIZE flag (set to 536mb) from the WASM build because it can unduly limit db exports via sqlite3_serialize(), as reported in [forum:75524f7342c1ba45\|forum post 75524f7342c1ba45]. (check-in: 747b4e3a9e user: stephan tags: branch-3.43)

14:54		When doing a DISTINCT aggregate that contains an ORDER BY, only the arguments to the aggregate need to be distinct, not the ORDER BY terms. (check-in: d2dbbdf719 user: drh tags: trunk)
12:58		Fix the amalgamation generator so that when it is reporting the Fossil version number in the header comment of the amalgamation, it does not elide the first hex digit of the version hash. (check-in: cc66f526bd user: drh tags: trunk)
10:37		Enhance the new xIntegrity method of the sqlite3_module object with new parameters that provide the name of the table being checked and a flag to indicate a "quick_check". Based on feedback in [forum:/forumpost/965c0d02ea\|forum post 965c0d02ea]. (check-in: bc8afa3f15 user: drh tags: trunk)

02:01		Fix the shell1.test test so to align with the new behavior imposed by [bce807cd48763273] - that backslash escapes only work without quoted arguments in dot-commands of the CLI. (check-in: 0db82b4281 user: drh tags: trunk)
01:55		Clear some picky warnings, sync w/trunk. (Closed-Leaf check-in: ee58425904 user: larrybr tags: expert-enhancement)
01:34		Add many more high-level wrappers to the JNI wrapper1 API. Correct the JNI bindings of sqlite3_strglob/strlike() to compare as the core lib does if their glob argument is NULL and the other is not. (check-in: 55c4b1dc40 user: stephan tags: jni-post-3.44)
2023-10-22
23:44		Fix [f5c01676fd281e93] so that it always preserves 8-byte alignment for Expr objects. Add new assert() statement to verify this. (check-in: 678a9728dc user: drh tags: trunk)
23:36		Add high-level window function wrapper to the JNI wrapper1 interface. (check-in: a27e747123 user: stephan tags: jni-post-3.44)
17:27		Do not do backslash escape processing on any unquoted strings in dot-commands in the CLI - on Windows or on posix-like systems either one. This brings the processing into alignment with the documentation, allows backslash-delimited filenames on Windows (as long as they are unquoted), and causes the CLI to work the same with regard to backslash escapes on both Windows and posix. (check-in: bce807cd48 user: drh tags: trunk)

2023-10-21
22:31		In the CLI, do not translate unquoted backslash escapes on dot-commands as that can damage filename arguments. (check-in: 4a0e2c6e17 user: drh tags: trunk)
20:34		Remove a branch that cannot affect the outcome from FkNoAction processing in fkey.c. Replace it with an assert(). (check-in: 023a9dbe83 user: drh tags: trunk)
20:03		Replace the patch at [5cb61c6788d7c017] with a better way to avoid failing PRAGMA integrity_check if a module implementation is not loaded, as the use of suppressErr can lead to problems. (check-in: be5737ee4f user: drh tags: trunk)
19:51		Check-in contains stray edit. (Closed-Leaf check-in: cbea52e9ef user: drh tags: mistake)

12:54		Add SQLITE_TESTCTRL_FK_NO_ACTION. (check-in: 563cf5f782 user: drh tags: fknoaction)
11:43		Adjust an EXPLAIN QUERY PLAN output in scanstatus2.test to account for a different loop order taken due to the removal of the view-scan optimization. (check-in: 9deb8b6915 user: drh tags: trunk)
11:34		Compress the content of the status line in testrunning.tcl so that all the same status information appears but with less punctuation and with "zero" values omitted, so that the status line will fit comfortably on an 80-column terminal window. (check-in: 9663513116 user: drh tags: trunk)
11:13		Create the new string_agg(X,Y) aggregate function which is an alias for the two-argument group_concat(X,Y) function, for compatibility with SQL-Server and PostgreSQL. (check-in: a3b3df8a9e user: drh tags: trunk)

19:59		Fix a problem allowing a COMMIT following an OOM to cause fts5 corruption. (check-in: fba3129d13 user: dan tags: trunk)
19:06		Fix PRAGMA integrity_check so that it does not raise an error if the schema contains a CREATE VIRTUAL TABLE that does not have its module loaded. (check-in: 5cb61c6788 user: drh tags: trunk)
18:09		Omit some redundant calls to strlen() used to find the size of Expr.u.zToken in sqliteExprDup(). This inefficiency was seen while working on the previous check-in, and I thought it best to fix it while it was fresh in mind. (check-in: b7a84eff5d user: drh tags: trunk)
17:15		Improvements to the sqlite3ExprDup() logic for faster performance and better run-time error detection. This check-in fixes the 5x oversize memory allocation bug from [f371e4c0f8ea73ae] as well as all other known issues that result from handing the ORDER BY clause of an aggregate function off of the pLeft pointer of the Expr object. (check-in: f5c01676fd user: drh tags: trunk)
17:06		Add the SQLITE_CHANGESETAPPLY_FKNOACTION flag to sqlite3session.h, for passing to sqlite3changeset_apply_v2() to cause all foreign key constraints to behave as if they were declared NO ACTION. (check-in: fc9f82ea08 user: dan tags: trunk)
15:47		Simplifications and optimizations to the Expr object duplication logic. The 5x multiplier crutch from [f371e4c0f8ea73ae] is still present. More fixes are still needed. (check-in: 56142a7816 user: drh tags: trunk)
14:05		Omit an unused constant from sessionfuzz.c to prevent a compiler warning. (check-in: a0cf7e24f9 user: drh tags: trunk)
12:23		Correct the opfs-sahpool VFS's xGetLastError() method to return the previous error code, not 0, on success. (check-in: 95a1dde631 user: stephan tags: trunk)
11:44		Merge trunk into the wasm-xGetLastError branch. (Leaf check-in: 48a9bd649d user: stephan tags: wasm-xGetLastError)
10:18		Use sqlite3ParserAddCleanup() instead of calling sqlite3ExprListDelete() directly when disposing of an unused ORDER BY in an aggregate function, to avoid disrupting ALTER TABLE data structures. (check-in: d083e42086 user: drh tags: trunk)

19:19		Fix an adverse interaction between the new aggregate ORDER BY logic and the expression compressor. Update 2023-10-20: Memory allocations were multiplied by a factor of 5 on line 1575 of expr.c. This was a debugging change that I neglected to remove prior to checking it. That change masks deeper problems that will be solved in later check-ins. (check-in: f371e4c0f8 user: drh tags: trunk)
19:08		In the TreeView logic (used for debugging only) do not show unnecessary fields of the Window object when a function has a FILTER. (check-in: d2c6b82c34 user: drh tags: trunk)
18:23		Fix an fts3 problem caused by reducing the page size using the undocumented "nodesize" option, then running an incremental-merge. (check-in: 2875dcb1ac user: dan tags: trunk)
18:07		Simplify the Expr compression logic slightly by adding the new EP_FullSize property to expressions that are exceptions to the rule and should not be compressed. (check-in: d5ae82ec52 user: drh tags: trunk)
13:35		Simplification to sqlite3GetVarint32() to avoid confusing gcov. (check-in: 89862c51ad user: drh tags: trunk)

12:36		New assert() statements to help verify correctness of the ORDER BY aggregate code. (check-in: 8b6fffb552 user: drh tags: trunk)
12:12		Fix the sqlite3ReferencesSrcList() routine so that it recognizes columns in the ORDER BY clause of an aggregate. Fixes a problem with [634286828dad873d] discoverd by dbsqlfuzz. (check-in: 3d26f1aaa4 user: drh tags: trunk)
01:26		Add support for ORDER BY on the argument list of aggregate functions. (check-in: 634286828d user: drh tags: trunk)

18:11		ORDER BY on aggregates seem to work, at least for simple smoke tests. Lots more testing is needed though. Surely there are many bugs. (check-in: 64c12a835b user: drh tags: agg-orderby)
13:58		Basic error checking. Resolve symbols in the aggregate ORDER BY expressions. (check-in: c83a53a574 user: drh tags: agg-orderby)
13:18		Enhance the parser so that it can accept an ORDER BY clause on a function invocation. For this incremental check-in, the ORDER BY clause is currently ignored. (check-in: 3a98ff24bf user: drh tags: agg-orderby)
2023-10-17
23:35		JS: replace one errant reference to 'self' with 'globalThis' and remove a separate dead-code 'self' reference. (check-in: da1a47932e user: stephan tags: trunk)

10:47		When an I/O or similar error occurs during a transaction with journal_mode=MEMORY, attempt to rollback before closing the journal, as all rollback information is forgotten when a memory rollback journal is closed. (check-in: 1d67f75de2 user: drh tags: trunk)
02:15		Harden API_ARMOR checks for sqlite3_stmt_scanstatus_v2(). (check-in: d3f38e813b user: stephan tags: trunk)

14:31		JNI: add scalar UDF support to the wrapper1 API. (check-in: a850535766 user: stephan tags: trunk)
13:04		JNI: initial draft (untested - requires more infrastructure first) of a UDF argument/result-handling interface which completely hides the C-style API from the client. (check-in: 43b10a5cf9 user: stephan tags: trunk)
10:38		JNI: cleanups in Tester2 and update the jar makefile target to account for [9fcdf96adca2]. (check-in: abc82bf4b8 user: stephan tags: trunk)
10:27		JNI: move the C-style API parts into the capi subpackage and the higher-level wrapper into (tentatively) wrapper1, so that CApi.java can support multiple independent higher-level wrappers without name collisions, and CApi can be made public but have the option to be elided from wrapper-level javadocs for wrappers which do not wish to expose it. (check-in: 9fcdf96adc user: stephan tags: trunk)
08:10		JNI: after calling a Java-side UDF, zero-out the pointer of the Java-side sqlite3_context and sqlite3_value array entries to avoid misbehavior if a client makes the mistake of holding a reference to one of those objects. (check-in: 9fc3104f76 user: stephan tags: trunk)
08:05		JNI: do not expose SQLITE_OPEN_... flags which are specific to VFSes. (check-in: 2b4e53d8be user: stephan tags: trunk)

14:34		Finish adding jsonb_ versions for all JSON routines that return JSON text. (check-in: 6daa7b6969 user: drh tags: jsonb)
13:16		Correct an undefined-value deref in the JS bindings, triggered by passing invalid args and then tripping over an undefined value while trying to report that. Reported in [forum:dd42df144651d779\|forum post dd42df144651d779]. (check-in: 1545f0f735 user: stephan tags: branch-3.43)
13:13		Correct an undefined-value deref in the JS bindings, triggered by passing invalid args and then tripping over an undefined value while trying to report that. Reported in [forum:dd42df144651d779\|forum post dd42df144651d779]. (check-in: fd46325407 user: stephan tags: trunk)
10:59		Make (almost) all SQLite3Jni.sqlite3_... members public but make the SQLite3Jni class package-private, which has the same foot-protection effect but makes it much simpler to patch SQLite3Jni to publicize the interface later. Remove some of the extraneous foot-shooting protection from indidivual functions, in lieu moving it to the still-pending higher-level interfaces. (check-in: 082b86683e user: stephan tags: trunk)
10:37		Merge in and close jni-ptr-passing branch. The remaining pointer-passing adaptation can be done incrementally without affecting the interface. (check-in: 7927c42410 user: stephan tags: trunk)
10:31		Make all native JNI sqlite3_...() bindings package-private as a foot-shooting protective measure (higher-level pre-native-call argument validation is largely pending). Move SQLTester.java and TesterFts5.java into the org.sqlite.jni package so that they can access the being-tested methods. (Leaf check-in: ec82f7251a user: stephan tags: jni-ptr-passing)
09:41		More work towards the new pointer-passing mechanism in JNI, and code-adjacent cleanups. (check-in: 6c63987e89 user: stephan tags: jni-ptr-passing)

19:47		The u.zJContent field of JsonNode for a string or label should NOT include the quotation mark delimiters. Ever. This is an inefficiency that really ought to be fixed on trunk, but that can wait until this branch lands. (check-in: 96f545f6f8 user: drh tags: jsonb)
16:37		Additional refactoring and cleanup. (check-in: 45dd176087 user: drh tags: jsonb)

19:11		Fix some minor memory issues so that all legacy tests now pass. (check-in: 1744bfc669 user: drh tags: jsonb)
18:23		Allow the sqlite3_user_data() function to be invoked with a NULL argument or with an sqlite3_context pointer from a virtual table. It returns NULL in both cases. (check-in: 2f49687371 user: drh tags: jsonb)
17:41		Merge trunk changes into the jsonb branch for the compiler warning fixes from two days ago. (check-in: cee113cc31 user: drh tags: jsonb)
17:27		The json_extract() function now works on BLOBs without the need to translate into an array of JsonNode objects. This is much faster. (check-in: 5853065b7e user: drh tags: jsonb)
17:23		Extract directly from BLOB is now complete and appears to work. (Closed-Leaf check-in: 3de58ec994 user: drh tags: jsonb-direct-extract)

2023-09-27
16:55		Performance tests for JSONB added. (check-in: 7c1be8e361 user: drh tags: jsonb)

11:01		Adapt JNI sqlite3_bind_...() bindings to the new pointer-passing method and correct the mapping of sqlite3_bind_zeroblob64() to use zeroblob64() instead of zeroblob(). Related internal API renaming. (check-in: 980d559fff user: stephan tags: jni-ptr-passing)
10:29		Add missing license headers to JNI annotation classes and extend the definition of @NotNull to include 0L as the equivalent of null to account for the current rework of how pointers are passed from Java to C. (check-in: bccdfeb9ef user: stephan tags: jni-ptr-passing)
09:58		Rework the JNI sqlite3_backup APIs to the new pointer-passing approach. (check-in: 48aeb1e2cd user: stephan tags: jni-ptr-passing)
2023-09-26
21:37		Start reworking JNI methods such that they pass void pointers from Java to C instead of passing their strongly-typed wrappers, as that is reportedly significantly faster than passing the wrapper objects to C and extracting the pointers there. There are still many, many functions left to rework for this. (check-in: 66c814dd47 user: stephan tags: jni-ptr-passing)
21:22		Fix harmless compiler warnings in the testfixture testing utility. (check-in: 5a39a02d2d user: drh tags: trunk)
19:49		JNI: implement AutoCloseable for the sqlite3 and sqlite3_stmt classes, and adjust a few tests to use it. Override Object.finalize() for sqlite3 class but not sqlite3_stmt (where it triggers a JVM crash for as-yet-unknown reasons). (check-in: b633d8bbdb user: stephan tags: trunk)
19:46		Merge partial-index constant value fixes from trunk into the jsonb branch. (check-in: 700bdbd738 user: drh tags: jsonb)
19:38		Fix yet another assert() in the partial-index constant value optimization. (check-in: f459d0806c user: drh tags: trunk)
19:30		Add in many jsonb_xxxx() interfaces. Still uses the internal JsonNode representation for transformations and search, but it does at least conform to the desired API design. Largely untested. (check-in: e6045b4e1b user: drh tags: jsonb)
19:26		Remove a NEVER() from a condition in the partial-index constant value optimization that can sometimes be true. (check-in: 63aea8c3e0 user: dan tags: trunk)
15:13		Merge all the latest trunk enhancements into jsonb branch. (check-in: ac242c4d47 user: drh tags: jsonb)

2023-09-25
17:46		In partial index scans, if the WHERE clause implies a constant value for a table column, replace occurences of that table column with the constant. This increases the likelihood of the partial index being a covering index. (check-in: 8d4160910d user: dan tags: trunk)
17:21		Another very minor tweak to code on this branch to save cycles. (Closed-Leaf check-in: 2c805dc681 user: dan tags: partial-index-terms)
17:14		When parsing JSON text into the BLOB format, only use node type JSONB_TEXTJ for an unquoted object label if the object label contains escape sequences. (check-in: a82ebbac3c user: drh tags: jsonb)
15:25		Change the order of an if..else... in new code to make it slightly faster. (check-in: f80dc64483 user: dan tags: partial-index-terms)

11:12		Fix a bad interaction between LEFT JOIN, bloom filters and partial indexes. (check-in: 5775f92b31 user: dan tags: partial-index-terms)
00:39		Cause sqlite3_exper_new() to replicate UDFs and custom collations early enough to appear in virtual column expressions during schema copy. [forum:/forumpost/e030aa4b3a\|forum post e030aa4b3a] (check-in: 8fc2c45558 user: larrybr tags: expert-enhancement)

15:34		Add extra tests for the fts5 xPhraseQuery API. (check-in: b5edea1631 user: dan tags: trunk)
06:50		Resolve the JNI FTS5 test5() crash, caused by two unrelated typos in JNI callback signature strings. That test now fails with an expected-vs-got mismatch but no longer dies in the native code. (check-in: 0233f310bf user: stephan tags: trunk)
06:37		Remove an invalid optimization from JNI code and add a missing check check for Java-side exception. (check-in: b8151f8797 user: stephan tags: trunk)
2023-09-22
20:21		In partial index scans, if the WHERE clause implies a constant value for a table column, replace occurences of that table column with the constant. This increases the likelihood of the partial index being a covering index. (check-in: 66ed7abdfa user: dan tags: partial-index-terms)
16:20		Fix minor parse-to-BLOB bugs. (check-in: 8b53b2e660 user: drh tags: jsonb)
14:33		Add the ability to render a binary BLOB back into valid canonical JSON. (check-in: 0b70cb77a4 user: drh tags: jsonb)

20:28		Simplifications and performance optimizations for the RTree extension. (check-in: 04a333f5fa user: drh tags: trunk)
19:51		Drop support for the view-scan optimization (check-in [609fbb94b8f01d67]) as it was causing multiple performance regressions. In its place, reduce the estimated row count for DISTINCT subsqueries by a factor of 8. (check-in: f911f1c497 user: drh tags: trunk)
19:27		Minor simplification to the DISTINCT output row count change. (Closed-Leaf check-in: 0738386d7c user: drh tags: rethink-viewscan)
19:00		Do not reduce subquery output row count estimates due to DISTINCT until after the decision of whether or not to use an index for ORDER BY has been made. (check-in: 27390051e8 user: drh tags: rethink-viewscan)
18:36		Allow expressions like "<tbl>.rowid" to refer to implicit rowid columns of tables in nested FROM clauses. (check-in: 59a1bbc69f user: dan tags: nested-from-rowid-expansion)
16:15		Experimental: Assume that a DISTINCT clause on a subquery reduces the number of rows returned by that subquery by a factor of 8. (check-in: 5a940e47d5 user: drh tags: rethink-viewscan)
14:06		The view-scan optimization was added to enhance the performance of one specific query, but it causes performance regressions on a host of others. Disable it (at least temporarily) in order to try to find an alternative way of fixing the one specific query that it was created to fix - an alternative way that does not cause performance problems for other unrelated queries.

17:42		Add a test for the java version of Fts5ExtensionApi.xRowid(). (check-in: 227facf879 user: dan tags: trunk)
16:45		According to [forum:/forumpost/9f6db917e1\|forum post 9f6db917e1], older MSVC compilers are unable to convert a double directly into an unsigned long long int, but must first go through a signed long long int. Work around this by restricting the range of doubles that are converted into long long integers so that only the lower 63 bits are used.

13:10		Improve the sqlite3IntFloatCompare() routine so that it is testable. (check-in: bb221381fa user: drh tags: trunk)
10:46		Do not set the global bUseLongDouble flag based purely on sizeof(long double) being more than 8. That is a necessary but not sufficient condition to use the long double routines. Instead, do a run-time test to verify that long double really does provide extra precision. (check-in: aa999d490b user: drh tags: trunk)

17:30		Omit the Reinsert algorithm from RTree. This causes most benchmarks to run faster, at the expense of having a slightly less dense and hence larger index (example: 33 entries/node versus 34 entries/node). (check-in: b3049a1d3d user: drh tags: rtree-performance)

13:12		In the ChooseLeaf algorithm of RTREE, do an initial pass through the cells of a node looking for solutions that involve no cell enlargement. Only look for the minimum cell enlargement if the enlargement is non-zero for all cells. This results in a performance improvement by reducing the number of calls to cellUnion().

10:20		The pageOnDirtyList() assertion is too slow even for debugging builds, for some corner cases. It makes the query appear to hang. So make it an EXPENSIVE_ASSERT instead. (check-in: bb9dcdaf32 user: drh tags: trunk)

13:27		More work on the JNI-specific mutexes. Rework the NativePointerHolder cache lookup to be slightly simpler and O(1) instead of O(N). (check-in: c84ded0e59 user: stephan tags: jni-threading)
12:20		Fix harmless compiler warnings reported by MSVC. (check-in: 391e21bb6e user: drh tags: trunk)
12:05		Enable SEH be default in Windows builds. (check-in: faae792fd5 user: drh tags: trunk)
08:28		JNI-internal docs and removal of obsolete code. (check-in: b62d93258b user: stephan tags: jni-threading)
2023-08-13
20:58		Internal API renaming for clarity's sake. (check-in: 911e4fc5aa user: stephan tags: jni-threading)
12:40		Add a mutex for auto-extensions, tied in to the open() process since that's the route into auto-extensions. (check-in: 8da97e0db4 user: stephan tags: jni-threading)
10:28		Add some docs and metrics for the new mutex internals. (check-in: 33d1780b43 user: stephan tags: jni-threading)
10:22		Remove SQLITE_DEBUG from JNI build. (check-in: 82f004cf74 user: stephan tags: trunk)
09:53		An initial attempt at protecting the JNI global state via mutexes at the C level instead of relying on Java's synchronized keyword. ~~It seems to work but increases the run time of the single-threaded SQLTester batch by roughly 3 times.~~ (Correction: it was just run on a slower machine. Cursory testing suggests that runtime performance hit might be, but likely isn't, as high as 10%.) (check-in: c64e6a52ac user: stephan tags: jni-threading)
2023-08-12
23:47		Bind sqlite3_interrupt() and sqlite3_is_interrupted() to JNI but with caveats regarding mutexing of the JNIEnv cache. Add a loud warning to the JNI 'dist' target that it should be built with JDK8 (a.k.a. Java 1.8) for compatibility reasons. (check-in: fbf99a2423 user: stephan tags: jni-threading)
21:39		Merge the Java Native Interface (JNI) binding into trunk. (check-in: 48b13edcec user: stephan tags: trunk)
21:08		Update wasm's push-testing rule to exclude files which were recently removed from the build. (check-in: 0a6930a7ff user: stephan tags: trunk)
20:50		Correct JNI .jar rules to only include .java/class files, not .* (*~ files). (Closed-Leaf check-in: 1ba7754045 user: stephan tags: jni)
19:58		Fix the mdevtest target so that it works with msvc. (check-in: 01f49448cd user: dan tags: trunk)
19:25		Fix testrunner.tcl so that it restarts itself using [testfixture] if its current interpreter does not support [package require sqlite3]. (check-in: 408be98ddd user: dan tags: trunk)
18:23		Have the mdevtest target support the OPTS variable on unix. (check-in: 940f58d9b9 user: dan tags: trunk)
17:36		Add "mdevtest" target to makefiles. Equivalent to running "devtest" on both debug and non-debug builds. (check-in: af354fbc0b user: dan tags: trunk)
15:37		More JNI docs. (check-in: 290028d3ca user: stephan tags: jni)
15:09		Further simplifications in the interface of the OutputPointer family of Java classes. (check-in: 962c3e0de2 user: stephan tags: jni)
12:16		Merge the latest trunk enhancements into the reuse-schema branch. (check-in: d2b0ddcc75 user: drh tags: reuse-schema)
10:39		Tweaks and docs for the OutputPointer family of Java classes. (check-in: 265c8fd0d4 user: stephan tags: jni)
10:27		Bind sqlite3_db_status() to JNI. (check-in: b79477a0af user: stephan tags: jni)
10:06		Bind sqlite3_status(64)() to JNI. (check-in: cefb6614e6 user: stephan tags: jni)
2023-08-11
22:40		Modernize the sqlite3 shell man page a bit, per [forum:d9aa201dee553bb2\|forum request]. (check-in: 3bc0693c46 user: stephan tags: trunk)
21:25		Add timing info to SQLTester. (check-in: b69b5facbf user: stephan tags: jni)
21:24		Merge trunk into jni branch. (check-in: 4f0aeeba02 user: stephan tags: jni)
20:32		Fix a makefile deps problem which caused ext/jni build to fail if sqlite3.c/h were not created beforehand. (check-in: 101de67077 user: stephan tags: jni)
19:38		Merge latest trunk changes, including support for handling of structured-exceptions in MSVC builds, with this branch. (check-in: cb3cf9bab0 user: dan tags: begin-concurrent)
19:36		Merge latest wal2 changes, including support for handling of structured-exceptions in MSVC builds, with this branch. (check-in: 331f2f3e5d user: dan tags: bedrock)
19:33		Merge latest trunk changes, including support for handling of structured-exceptions in MSVC builds, with this branch. (check-in: 00bfae9ffa user: dan tags: wal2)
19:31		If SQLITE_USE_SEH is defined, handle structured-exceptions thrown by MSVC builds if the *-shm file mapping is accessed after it becomes invalid for some reason. (check-in: 8a6b0c2493 user: dan tags: trunk)
18:59		Minor SQLTester test tweaks and have 'make tester' include the out-of-tree tests if they are found. (check-in: 6c8538d834 user: stephan tags: jni)
18:31		Fix a problem with handling savepoints in BEGIN CONCURRENT transactions. (check-in: ca422d00d7 user: dan tags: bedrock)
18:25		Fix a problem with handling savepoints in BEGIN CONCURRENT transactions. (check-in: 4a5c0439ae user: dan tags: begin-concurrent)
18:04		Bind sqlite3_sql() and sqlite3_expanded_sql() to JNI. Start marking C-side functions which would need explicit mutex support if we remove 'synchronized' from their Java entry points (but there are many more left to mark). (check-in: c7fb32d1ef user: stephan tags: jni)
17:45		Add a doc link for the new sqlite3_js_posix_create_file(). (check-in: 0d7aac45b8 user: stephan tags: trunk)
17:38		Add sqlite3.capi.sqlite3_js_posix_create_file() and oo1.OpfsDb.importDb() as alternatives for the newly-deprecated sqlite3_js_vfs_create_file(). (check-in: da6eaf8d82 user: stephan tags: trunk)
14:31		Deprecate sqlite3_js_vfs_create_file() because, it was discovered today, its out-of-scope use of the sqlite3_vfs, sqlite3_file, and sqlite3_io_methods APIs triggers unresolvable assertions in the core when built with SQLITE_DEBUG. (check-in: f3647a3ac8 user: stephan tags: trunk)
11:46		Merge all the latest trunk enhancements into the bedrock branch. (check-in: 859932ebce user: drh tags: bedrock)
11:40		Merge the latest trunk enhancements into the wal2 branch. (check-in: fe1bf30ca0 user: drh tags: wal2)
11:34		Merge the latest trunk enhancements into the begin-concurrent branch. (check-in: 7cb2b4e35f user: drh tags: begin-concurrent)
11:30		Provide the -DSQLITE_LEGACY_JSON_VALID compile-time option to restore the (incorrect) legacy behavior of json_valid(NULL). (check-in: 00bc9f1b57 user: drh tags: trunk)
11:24		Fix bug in the test case for the previous check-in. (Closed-Leaf check-in: c5daae8861 user: drh tags: legacy-json-valid)
11:23		Update test scripts specific to this branch so that they work on windows. (check-in: f0ca13edad user: dan tags: wal2)
11:12		Up until version 3.42.0, there was a bug in json_valid() such that it would return False (0) for a NULL input. That bug is fixed in 3.42.0. This check-in adds a compile-time option -DSQLITE_LEGACY_JSON_VALID that restores the old buggy behavior for applications that depend on it. (check-in: 15c2eadbff user: drh tags: legacy-json-valid)
2023-08-10
21:50		Mark _all_ JNI binding funcs as synchronized so that Java can lock them and protect our global-state access. The alternative is writing a mountain of C-side code to do the same thing. (check-in: afe190a940 user: stephan tags: jni)
21:29		Work around jdk8 and jdk19 mangling the C name of sqlite3_db_config() differently. Correct the variadic arg handling of the JNI-side subset of sqlite3_db_config() options. (check-in: 746894c3c0 user: stephan tags: jni)
21:20		Add tests for structured-exception-handling and wal2. Fix a problem with the same. (Leaf check-in: 87242777ec user: dan tags: wal2-shm-exceptions)
20:52		Add a working dist zip file for the JNI bits. (check-in: d6a4d212ce user: stephan tags: jni)
18:58		Experimental merge of the wal-shm-exceptions and wal2 branches. (check-in: fd58c61624 user: dan tags: wal2-shm-exceptions)
18:57		Initial pass at 'make dist' rules for the JNI bundle, but they still need a bare-bones, posix-make-compatible makefile to include in the bundle. (check-in: ff54e66a4d user: stephan tags: jni)
18:50		New testcase() macro in the tokenizer, to better document its behavior. (check-in: b2fdac0b15 user: drh tags: trunk)
17:39		Merge trunk into jni branch for the newly-relocated version-info tool. (check-in: cc8e8cba67 user: stephan tags: jni)
17:32		Move ext/wasm/version-info.c to tool/ for re-use in build other dist bundles. (check-in: 4b0871fd36 user: stephan tags: trunk)
17:07		Merge latest trunk changes into this branch. (Leaf check-in: 3ed89c344f user: dan tags: wal-shm-exceptions)
17:04		Mark test script wal2big.test as "TESTRUNNER: slow". (check-in: ae7f3bcb5b user: dan tags: wal2)
17:03		Merge latest trunk changes into this branch. (check-in: 72f7807b34 user: dan tags: wal2)
16:42		Add SQLTester --keep-going flag to allow it to continue to the next script after an error. (check-in: 4d635f781b user: stephan tags: jni)
13:10		Document that auto-extensions registered via JNI will fail if they open a db (to avoid triggering an endless loop in the auto-extensions). Discover the hard way that JDKv19 creates different mangled JNI names for some functions than JDKv8. Start reformatting much of the JNI API decls in prep for making them even longer. (check-in: 99c0941f1c user: stephan tags: jni)
12:36		Resolve two assertions in the auto-extension JNI which were triggered via new SQLTester infrastructure. Move SQLTester's db-init SQL injection into an auto-extension. (check-in: 2952906c30 user: stephan tags: jni)
11:15		Make test completion status more visible at a glance on modern terminals. (check-in: a4e96c306c user: stephan tags: jni)
11:04		Disable REQUIRED_PROPERTIES handling in SQLTester, per /chat. Scripts with that directive are now skipped. (check-in: ddc534cb25 user: stephan tags: jni)
10:58		Add a visual indicator (emoji) to TestScript verbose messages, dependent on the message's level of verbosity. (check-in: dc323d3894 user: stephan tags: jni)
10:44		Add the current --testcase name to SQLTester --verbose output. (check-in: f87367402b user: stephan tags: jni)
10:34		More SQLTester docs. Add --verbosity command to help zoom in on script areas while debugging. Spice up test-start/end output with some emoji. (check-in: 8dd0802149 user: stephan tags: jni)
05:25		Give DbException the option of closing the db to simplify error handling in one case. (check-in: 908c9a4450 user: stephan tags: jni)
05:14		Initial version of REQUIRED_PROPERTIES support for SQLTester, with TEMPSTORE_(FILE/MEM) and RECURSIVE_TRIGGERS options. (check-in: 48d16c9d2f user: stephan tags: jni)
04:24		Generic cleanups and fixes in SQLTester. (check-in: fc5d3cc30d user: stephan tags: jni)
02:09		Change the SQLite3Jni API annotations to use SOURCE retention (used only at compile-time). (check-in: 3c3fea6bf2 user: stephan tags: jni)
01:44		Move all of the SQLTester code into a single file, since it's only got 1 public class. Remove 'public' from many methods which don't need it. Add more documentation to it. (check-in: 2815d67695 user: stephan tags: jni)
01:19		Defer static JNI-side init of SQLTester until main() is called so that its auto-extensions do not leak over to clients of the main library. (check-in: e461fdd53b user: stephan tags: jni)
01:05		Merge trunk into jni branch. (check-in: 52fa6f7841 user: stephan tags: jni)
01:03		Treat all args to --glob as a single glob. (check-in: 4737bd3457 user: stephan tags: jni)
00:58		Remove --print's ability to read ahead. (check-in: 15cfee972b user: stephan tags: jni)
00:34		Replace the SQLTester infrastructure with a line-oriented, non-regex-heavy parser. Add --column-names command. (check-in: 88863908ee user: stephan tags: jni)
2023-08-09
23:47		Port the SQLTester 'v1' commands to the 'v2' evaluation bits. Still TODO is swapping out v1 with these separate impls. (check-in: 0cf57e5b0f user: stephan tags: jni)
22:30		Correct REQUIRED_PROPERTIES handling to not fail if there are no properties. (check-in: 7a19bef4f5 user: stephan tags: jni)
22:18		More for the SQLTester rework. Can read input and dispatch commands, but only --print is currently implemented. (check-in: 4fa2ad33ed user: stephan tags: jni)
19:51		Initial sketches of a line-by-line parser for SQLTester to overcome its compatibility shortcomings. Far from complete. (check-in: 43534cd042 user: stephan tags: jni)
18:25		Adapt TestScript to skip REQUIRED_PROPERTIES, per [7a07863e082664da], and improve a couple of adject reasons-for-skipping messages. (check-in: f937097e9b user: stephan tags: jni)
17:47		Add an extra constraint to the test-script-interpreter.md spec. (check-in: 7a07863e08 user: drh tags: jni)
17:23		SQLTester --result command: do not double-{}-wrap error messages and do not throw on db error. (check-in: f7be20f5a6 user: stephan tags: jni)
17:04		Move the test command body's trim() back into the TestScript class (to simplify Command-level code) but do it after double-verbose has had the chance to emit it as-is (so that debug output is not mangled by the trim). (check-in: f15ecb68f7 user: stephan tags: jni)
16:56		Tweak the SQLTester --verbose and double-verbose output a bit for legibility. (check-in: 46b79afaaf user: stephan tags: jni)
16:29		Strip --oom commands from SQLTester input since (A) we can't currently do anything with them and (B) they can appear as body content of --testcase commands and the current parser cannot deal with that. If --verbose is provided once, emit the name and args of each command as it's run. If --verbose is used twice or more, also emit the command's body text, if any. (check-in: 0770e8467d user: stephan tags: jni)
16:03		Update the definition of "special characters" for the SQLTester and correct the code to match it. (check-in: 217f6e0c9c user: stephan tags: jni)
15:46		Extend TestScript to be able to report why it should be skipped. Expand the test-skipping rules to account for the current spec doc. Add the {} empty-string case to the spec doc. (check-in: 4fcc8cb0cc user: stephan tags: jni)
14:47		Add a test for the --null command. (check-in: 83ac815deb user: stephan tags: jni)
14:43		Extend SQLTester glob support with '#'. (check-in: 756ef83f45 user: stephan tags: jni)
14:24		Implement the SQLTester's result escaping rules. (check-in: 61bb950873 user: stephan tags: jni)
13:51		Add --json and --json-block SQLTester commands. (check-in: 478129d901 user: stephan tags: jni)
13:16		Add SQLTester --tableresult command. (check-in: 8c5b6d893d user: stephan tags: jni)
12:05		Clean up the SQLTester output a bit by using the module name, instead of filename, where appropriate. (check-in: 5323e4fd25 user: stephan tags: jni)
11:10		Document SQLTester's --print command and add some argument validation to it. (check-in: ab9c945bb0 user: stephan tags: jni)
11:05		Rework how SQLTester's Command objects are dispatched and how TestScript stores its command entries. (check-in: f929f1f7f7 user: stephan tags: jni)
09:56		Some minor tweaks in SQLTester in prep for larger refactoring. (check-in: 1d93f93ac9 user: stephan tags: jni)
2023-08-08
22:10		Remove the current-statement tracking from the JNI internals because it will break down in the face of client-side mixed-mode native/java code, e.g. in cases like SQLTester. This makes tracing of sqlite3_stmt a micron slower but also reliably correct. (check-in: 4c0ec89dca user: stephan tags: jni)
21:22		Adapt JNI build to be buildable with or without SQLTester. (check-in: adae7d7869 user: stephan tags: jni)
21:05		Add SQLTester dup() and dup_count() UDFs. Correct arg handling of the --run command. (check-in: 0dba3073f4 user: stephan tags: jni)
20:41		Correct --result arg count check and add infrastructure to let us add custom C-side behavior to SQLTester via an auto extension. (check-in: bb8321702e user: stephan tags: jni)
20:15		If SQLTester now treats a no-args --result as comparing against an empty string. (check-in: 49005ca5cc user: stephan tags: jni)
20:02		Add glob/notglob commands to SQLTester and complete the interrupted-midway impls of the strglob() and strlike() JNI bindings. (check-in: 4ba98ec0bf user: stephan tags: jni)
19:20		When SQLTester hits an unknown command, emit a warning and skip the rest of that script instead of aborting the whole run, per /chat discussion. Reduce verbosity a bit. (check-in: 3e78d22d04 user: stephan tags: jni)
17:36		Minor cleanups in sqlite3Int.h. By reordering some fields in the Parse object, it packs more tightly and uses less memory and less CPU to initialize. (check-in: aa6de539c0 user: drh tags: trunk)
16:53		Fix an issue in the amalgamation generator in which it was not correctly expanding the SQLite version in the header comment. (check-in: 293f6191e9 user: drh tags: trunk)
14:58		Correct the spacing output of multi-select SQL blocks for SQLTester --result. (check-in: 8d98645a9e user: stephan tags: jni)
14:49		Updates to the test script interpreter spec: Rather than failing immediately upon encountering an incompatibility, simply abandon the rest of that particular input file. (check-in: d2c99b96f4 user: drh tags: jni)
14:40		A number of baby steps for SQLTester.java. It can now handle basic --result cases. (check-in: 0404f688f6 user: stephan tags: jni)
14:25		Add a few words of clarification on how the SQLite Test Script Interpreter should be initialized to start each test script. (check-in: 3aa2b5a5ca user: drh tags: jni)
13:05		Correct JNI sqlite3_prepare() to emit a null stmt handle when the C counterpart succeeds but results in a NULL pointer. (check-in: 94628f88b5 user: stephan tags: jni)
11:46		Implement the new/open/close SQLTester commands. (check-in: dc823bf00f user: stephan tags: jni)
11:46		Add a JNI-layer sqlite3.toString() for debugging. (check-in: 456691649a user: stephan tags: jni)
10:58		Bind sqlite3_strlike/strglob() to JNI. (check-in: eb5440f71b user: stephan tags: jni)
09:45		SQLTester: add print command and improve argument error reporting infrastructure. (check-in: 1b6e84f6aa user: stephan tags: jni)
00:59		Add missing license header. Minor cleanups in SQLTester. (check-in: 5be50fd588 user: stephan tags: jni)
00:37		Rework SQLTester dispatching and add stub impls for several commmands. (check-in: 9e61af75ac user: stephan tags: jni)
2023-08-07
23:59		Add command dispatcher to SQLTester. (check-in: e0a06931e9 user: stephan tags: jni)
23:04		SQLTester now ignores tests which contain constructs specified in the spec doc. (check-in: ecaeee652a user: stephan tags: jni)
22:32		SQLTester can now split a test script into a series of individual commands. (check-in: d3d1accc8b user: stephan tags: jni)
22:02		SQLTester can now read a script and strip it of all noise content. (check-in: 59bd392817 user: stephan tags: jni)
21:04		Initial skeleton for adding an SQL-driven test script interpreter for the JNI bindings. (check-in: 2aa8f0edec user: stephan tags: jni)
17:09		Enhance sqlite3_vtab_nochange() so that it works with "UPDATE ... FROM ..." statements. Use this to allow some updates on fts5 contentless-delete tables. (check-in: 27ff86e4d8 user: dan tags: trunk)
16:15		Changes so that sqlite3_vtab_nochange() works with "UPDATE ... FROM...". Use this to allow UPDATE on a contentless fts5 table if new values are supplied for all indexed columns. (Closed-Leaf check-in: 16cd2161e3 user: dan tags: fts5-contentless-delete)
11:18		When converting a Java exception to a db error message, use Throwable.toString() instead of getMessage() so that the exception type's name is included. More internal API renaming for consistency. (check-in: 2d44720d06 user: stephan tags: jni)
10:59		Lots of JNI internal API renaming, for consistency, and moving-around of utility functions. Make it safe for more callback types to throw. (check-in: 9a494394b9 user: stephan tags: jni)
10:01		JNI API renaming to better match the C API. (check-in: 6e0bd03d0b user: stephan tags: jni)
09:44		Rename fts5_api pContext parameters to pUserData, per /chat discussion. This is a cosmetic change made to reduce confusion between those parameters and the two other context-type parameters in that API. (check-in: 2ca064d8eb user: stephan tags: trunk)
01:06		Make sqlite3_stmt() Java ctor private - it's only constructed from JNI code. (check-in: ce82c42f15 user: stephan tags: jni)
00:29		Minor internal cleanups and additional test metrics. (check-in: fa0a6b6e8e user: stephan tags: jni)
00:06		Bind the auto-extension APIs to JNI. (check-in: 746a5fa079 user: stephan tags: jni)
2023-08-06
22:09		Rework the sqlite3_open(_v2)() order of operations so that pending auto-extension support can get ahold of the open-time Java state despite the Java/C (sqlite3*) binding not having yet been established. (check-in: 34da294ab5 user: stephan tags: jni)
21:29		Completely rework how the JNI sqlite3_open(_v2) and sqlite3_prepare(_vN)() bindings deal with output pointers to give the JNI side full control over the origin of db and stmt handles (necessary for solving chicken/egg situations in auto-extensions and prepare-time trace). Lots of adjacent internal API renaming. (check-in: 644999caff user: stephan tags: jni)
20:01		Start adding JNI-side support for auto extensions, but hit a brick wall which requires slightly awkward semantics changes in the JNI bindings for sqlite3_open(_v2)() to resolve, so stash this #if'd out for the time being. (check-in: 77a32d238e user: stephan tags: jni)
15:01		Doc cleanups. (check-in: 5f56b00770 user: stephan tags: jni)
14:19		Bind sqlite3_config() to JNI for call variants taking (int,int) and (int,const char ) variadic arguments. (check-in: 6119289da8 user: stephan tags: jni)
13:02		JNI-internal cleanups and API renaming. Add a C-side java-string-to-utf8 conversion. (check-in: 672d85795d user: stephan tags: jni)
11:05		Remove doc outdated warning about sqlite3_trace_v2() JNI binding being incompatible with MUTF-8. Use new to-string capability to simplify Fts5ExtensionApi::xColumnText() JNI binding. (check-in: ebcfc2379b user: stephan tags: jni)
10:49		Add a way to convert from standard UTF-8 to a Java string (JNI lacks this capability). (check-in: 07dd082c9e user: stephan tags: jni)
10:14		Bind sqlite3_db_filename() and (closely related) (A) add many more docs about the UTF-8/MUTF-8 discrepancy (B) start adding internals to enable us to perform the standard-UTF-8-to-Java conversion from C. (check-in: 586720fa71 user: stephan tags: jni)
2023-08-05
22:41		Bind sqlite3_set_authorizer() to JNI. (check-in: e0fa031359 user: stephan tags: jni)
21:35		Refactor the per-JNIEnv cache from a fixed-size static array to a linked list of dynamically-allocated entries. Uncache all per-db state (which is necessarily JNIEnv-specific) when the corresponding JNIEnv is uncached. (check-in: 9dd8b78419 user: stephan tags: jni)
20:19		Add SQLite3Jni.uncacheJniEnv(), a way for Java threads to clear their thread-specific cached state from the JNI bindings when they're about to terminate (or are otherwise done using the library). (check-in: 7468f8761b user: stephan tags: jni)
19:20		In the JNI docs, note that the sizeof SQLITE_TRANSIENT and SQLITE_STATIC should ideally be the same as the platform's pointer size. (check-in: 7d4ac44ec4 user: stephan tags: jni)
19:15		Tiny doc typo fixes from [forum:31eb707250\|forum post 31eb707250]. No code changes. (check-in: 8ede50082e user: stephan tags: trunk)
12:48		JNI internal refactoring and cleanups. (check-in: 7397973a2f user: stephan tags: jni)
11:16		Bind Fts5ExtensionApi::xUserData() to JNI and extend xCreateFunction() to accept that argument. In test code, use assert() instead of exceptions if assert() is enabled so that test failures (exceptions) thrown via callbacks do not get suppressed (which they otherwise necessarily are to avoid crashing the host app). (check-in: e438373776 user: stephan tags: jni)
04:30		Add missing Fts5PhraseIter.java to the build. (check-in: 96281ad0d5 user: stephan tags: jni)
04:23		Bind fts5_api::xCreateFunction() to JNI and demonstrate it with a test. (check-in: c653bf16cb user: stephan tags: jni)
01:28		Start adding fts5_api to JNI. (check-in: 14d18fe983 user: stephan tags: jni)
00:40		Bind the remaining Fts5ExtensionApi methods to JNI, noting that all are completely untested because the higher-level bits needed to do so are still missing. (check-in: 23383c1dfd user: stephan tags: jni)
2023-08-04
16:01		In the opfs-sahpool VFS's importDb() and exportFile() methods, throw if the actually-wrote/read amounts differ from the expected-to-write/read amounts, per feedback in [forum:a4122e986f\|forum post a4122e986f]. (check-in: a617ebf4e5 user: stephan tags: trunk)
15:38		More work on the JNI binding of fts5 customization (still a long ways to go). (check-in: 1a246fd216 user: stephan tags: jni)
13:29		Merge the json_remove() bug fix from trunk into the bedrock branch. (check-in: a8872aa588 user: drh tags: bedrock)
13:27		Eliminate code duplication in the two JNI tester classes. (check-in: 63e7bbe3d5 user: stephan tags: jni)
13:24		Merge the json_remove() bug fix from trunk into the wal2 branch. (check-in: e6c066cae4 user: drh tags: wal2)
13:19		Fix a bug in the jsonLookup() routine used to search JSON. Bug was introduced by the recent (unreleased) JSON caching enhancements check-in [a4c1af616e672a0d] merged into trunk at [df099ad713011b67]. (check-in: ba7a66db13 user: drh tags: trunk)
13:03		FTS-related JNI refactoring. Move FTS-specific tests into their own class and dynamically load it, if possible, from the main test app. (check-in: b7a8428fcd user: stephan tags: jni)
12:44		More work towards binding FTS5 customization to JNI. Add Fts*.java files missing from previous checkin. (check-in: 91263178f4 user: stephan tags: jni)
11:10		Change comment on Fts5ExtensionApi.iVersion from "always set to 3" to "always set to 2". (check-in: b7de399c27 user: dan tags: trunk)
11:08		Start including fts5 customization bits into JNI, but it's far from functional. (check-in: abaf5edd04 user: stephan tags: jni)
09:53		Improve internal error handling in the JNI create_function() impl. (check-in: 2c88390faa user: stephan tags: jni)
08:45		Resolve the timing/ordering issue of a JS-to-WASM-converted xDestroy() function being uninstalled from WASM right before the underlying native call tries to call it. This has been a long-unnoticed bug which appears only when removing such functions or replacing them. (check-in: 031c9a76b6 user: stephan tags: trunk)
08:41		Part 2 of the fix from [a0f808363318c00fd1db78b]. (check-in: 5c3104228d user: stephan tags: trunk)
08:39		More work towards fts5 customzation in JS. (Leaf check-in: ce2a65d80f user: stephan tags: wasm-fts5)
2023-08-03
23:26		Merge the latest trunk enhancements into the bedrock branch. (check-in: 877ffece05 user: drh tags: bedrock)
23:22		Merge the latest trunk enhancements into the wal2 branch. (check-in: 6fa71e1119 user: drh tags: wal2)
22:43		Minor internal cleanups in the JS-side fts5 cleanup steps. (check-in: 2666f52e88 user: stephan tags: wasm-fts5)
21:14		Retain all xDestroy method WASM proxies created for fts5_api::xCreateFunction() until the db is closed, then free them all at once. (check-in: f4b9743abd user: stephan tags: wasm-fts5)
20:45		Rework the fts5 db-close cleanup to avoid that fts5 internally calls a just-unbound-from-wasm xDestroy() method. There is still work to do here to cover the case of fts5 functions being replaced (in which all xDestroy methods have to be retained until the db is closed). (check-in: 795f22421b user: stephan tags: wasm-fts5)
20:02		Part 2 of the fix from [a0f808363318c00fd1db78b]. (check-in: ce0674b192 user: stephan tags: wasm-fts5)
18:46		Resolve the timing/ordering issue of a JS-to-WASM-converted xDestroy() function being uninstalled from WASM right before the underlying native call tries to call it. This has been a long-unnoticed bug which appears only when removing such functions or replacing then. (check-in: a0f8083633 user: stephan tags: wasm-fts5)
18:14		Fix harmless scan-build warnings. (check-in: 65a8716d8a user: drh tags: trunk)
16:22		Fix a discrepancy between sqlite3_values_to_js() and its API docs/intended behavior. (check-in: 7b85c68fe2 user: stephan tags: trunk)
16:21		More infrastructure towards binding FTS5 customization support to WASM. (check-in: 163e3e44b1 user: stephan tags: wasm-fts5)
16:02		Fix a discrepancy between sqlite3_values_to_js() and its API docs/intended behavior. (check-in: 16658b3c64 user: stephan tags: wasm-fts5)
13:30		Fix build problems associated with SQLITE_OMIT_WSD and SQLITE_OMIT_TRIGGER. (check-in: de031a5ec8 user: drh tags: trunk)
13:07		Fix a test case whose value changes under the no_optimization permutation due to the recent change to add the ability for SQLITE_TESTCTRL_OPTIMIZATION to disable one-pass. (check-in: 976e39c632 user: drh tags: trunk)
12:41		Unix builds now assume the presence of nanosleep() in the standard library. The -DHAVE_NANOSLEEP=0 compile-time option can be used to build on systems (if any still exist) where this is not the case. (check-in: 779d5dc879 user: drh tags: trunk)
07:20		Initial work on exposing the FTS5 APIs to wasm, per [forum:28402061cb\|request in the forum]. This builds and loads the structs into JS but is completely untested. (check-in: 52c8b73ae3 user: stephan tags: wasm-fts5)
2023-08-02
18:20		If a query has an ORDER BY clause that only refers to result columns of the left-most table and the left most table is a MATERIALIZED common table expresion, then attempt to push the ORDER BY clause down into the subquery. (Leaf check-in: 8e7a70b2bb user: drh tags: order-by-push-down)
17:29		More JNI-internal docs. Correct handling of a Java exception if a trace callback throws. (check-in: 306b269a01 user: stephan tags: jni)
17:20		Internal doc additions in the JNI bits. (check-in: b56643644e user: stephan tags: jni)
16:06		Performance optimization for JSON rendering logic. (check-in: ea0b9aecba user: drh tags: trunk)
13:45		Remove an unreachable branch in the ascii-to-floating-point conversion that was added by [e989a37ff9d5b52e]. (check-in: c4347e4400 user: drh tags: trunk)
13:38		Stricter enforcement of the idea that a MATERIALIZED common table expression is an optimization fence. (check-in: 354425f8d9 user: drh tags: trunk)
13:29		Remove a condition from query flattening that is now taken care of by the caller. Factor out the reverse_unordered_selects processing from the main loop of sqlite3WhereBegin() for performance. (Closed-Leaf check-in: f068f105fb user: drh tags: materialize-order-by)
12:39		Simplify the select.c logic that enforces the optimization fence around a MATERIALIZED common table expression. Do not allow the reverse_unordered_selects setting to affect a fenced CTE that itself has an ORDER BY clause. (check-in: 165b9bda24 user: drh tags: materialize-order-by)
11:06		Never flatten a CTE that is labeled MATERIALIZED. This is really something of a bug fix because the documentation says that a MATERIALIZED CTE is an optimization barrier. (check-in: b7ef9796f5 user: drh tags: materialize-order-by)
00:09		When a query is inside an AS MATERIALIZED CTE, do not attempt the omit-ORDER-BY optimization. If the developer specifies MATERIALIZED, that means he wants the sort to actually happen. (check-in: aa769ee747 user: drh tags: materialize-order-by)
2023-08-01
19:10		Avoid ASAN warnings when converting over-sized long double values into double. (check-in: e989a37ff9 user: drh tags: trunk)
16:41		Filter the wasmfs-specific JS module result type check out of non-wasmfs builds. (check-in: ef7c121049 user: stephan tags: trunk)
16:38		Fix part 2 of 2 for /fiddle: a make deps problem which caused fiddle to load but fail to run when sqlite3.c was missing. (check-in: 6011bc2676 user: stephan tags: trunk)
16:17		Fix part 1 of 2 for /fiddle not running: build flags which were renamed during refactoring. (check-in: 214ffeeff7 user: stephan tags: trunk)
11:03		Fix an assert() in fts5_index.c that might fail when dealing with corrupt records. (check-in: aa55c83f35 user: dan tags: trunk)
10:19		More docs for the Java side of the JNI bindings. (check-in: d8e9bcee96 user: stephan tags: jni)
09:44		Internal exception-handling cleanups in the JNI bindings. (check-in: 057b1d4f6f user: stephan tags: jni)
08:48		Minor JNI-related doc tweaks and code re-ordering. (check-in: b663b27e42 user: stephan tags: jni)
01:07		Remove redundant comparison operator. (check-in: 0189843298 user: drh tags: trunk)
00:34		Restore part of the UPDATE one-pass optimization that was removed by check-in [2c56b984a0bd3be5]: only disable one-pass if the WHERE clause contains a subquery. Allow subqueries in the SET expressions. Fix for performance problem reported by [forum:/forumpost/8ab195fd44e75ed0\|forum post 8ab195fd44e75ed0]. (check-in: 42916af9fc user: drh tags: trunk)
2023-07-31
22:03		Restrict the new column cache to table-btree, which is the common case anyhow. That way, writes to indexes do not need to clear the column cache. (check-in: 659284ab0e user: drh tags: trunk)
20:02		The original column-cache implementation from check-in [ab1edcc7fedcf279] (merged to trunk at [771fe35074b50b8d]) is unsound. This check-in fixes the issue. Had to give back a little performance, the optimization is still a overall win. (check-in: ec95e970fb user: drh tags: trunk)
17:39		Add bit to sqlite3_test_control(SQLITE_TESTCTRL_OPTIMIZATIONS) that will disable the one-pass optimizating in DELETE and UPDATE. (check-in: 22f6dd5cd3 user: drh tags: trunk)
17:20		Improved debug tracking of the Parse.nQueryLoop value. (check-in: 4a8a17498e user: drh tags: trunk)
13:52		Experimentally change the JNI sqlite3_trace_v2() callback type to have more convenient access to the current Java-side sqlite3_stmt at the cost of some uncomfortably fiddly current-statement tracking in the JNI layer. Subject to change. (check-in: 459db332af user: stephan tags: jni)
12:10		Add some JNI-internal metrics, accessible via passing -v when running Tester1.java. Document an OpenJDK bug which leads to incorrect -Xlint:jni warnings. (check-in: a5d68a6b64 user: stephan tags: jni)
10:55		Correct a mis-cast in the JNI wrapper which just happened to accidentally work. Update JNI binding of sqlite3_context_db_handle() to return the bound-at-open() db instance instead of a new/temp proxy object. (check-in: 9faca5d9ed user: stephan tags: jni)
10:42		Add another test for JNI-bound scalar UDFs. (check-in: 8b322d92e2 user: stephan tags: jni)
10:22		Update some internal docs for the past two checkins. Add a way to dump out some debug info about the current JNI environment. (check-in: ac9b8bb1e6 user: stephan tags: jni)
10:08		Refactor the busy-handler-specific JNI hook type to use the generic hook type. (check-in: d9efdc6dd2 user: stephan tags: jni)
09:45		Refactor the collation-specific JNI hook type to use the generic hook type. (check-in: 02c1d3b650 user: stephan tags: jni)
09:28		Internal JNI doc tweaks. (check-in: f4aa2c8288 user: stephan tags: jni)
07:15		Consolidate triplicated xDestroy()-calling code. Remove some unnecessary casts. (check-in: 24c0763d0e user: stephan tags: jni)
2023-07-30
18:41		Internal JNI API renaming. (check-in: fcfc070673 user: stephan tags: jni)
17:24		Internal JNI refactoring towards consolidating support for callbacks with and without finalizers. (check-in: 120983a570 user: stephan tags: jni)
13:47		Mark the Java wrapper classes of the C-native types as 'final' (cannot be subclassed). (check-in: 4fd3d93623 user: stephan tags: jni)
13:30		Minor tweaks and optimizations in the JNI bindings. (check-in: 41fb5898f1 user: stephan tags: jni)
11:36		Bind sqlite3_collation_needed() to JNI. Related adjacent cleanups and fixes. (check-in: 16ff167691 user: stephan tags: jni)
10:47		Internal JNI refacoring to support the pending sqlite3_collation_needed() callback. Correct a bug in the linked-list handling of PerDbStateJni which triggered an assert(). (check-in: 7ac6614e69 user: stephan tags: jni)
09:45		Incremental checkin to minimize the diff while narrowing in on an assertion caused by refactoring. (check-in: 2d7a91b139 user: stephan tags: jni)
08:12		Consolidate some warnings for java callbacks which must not throw but do. (check-in: 5e592ed2df user: stephan tags: jni)
07:44		Bind sqlite3_update_hook() to JNI. (check-in: a5bbaa9017 user: stephan tags: jni)
06:44		Bind sqlite3_rollback_hook() to JNI. (check-in: 5f8ee44098 user: stephan tags: jni)
06:00		Add commit hook failure to JNI tests. (check-in: be4459b495 user: stephan tags: jni)
05:50		Bind sqlite3_commit_hook() to JNI. (check-in: c687297fca user: stephan tags: jni)
04:31		Bind sqlite3_progress_handler() to JNI. Add some metrics to Tester1.java. (check-in: 437ecfe8ab user: stephan tags: jni)
03:54		Add tests for SAHPoolUtil.exportFile() and importDb(). (check-in: 4aa88b8fb1 user: stephan tags: trunk)
2023-07-29
22:58		Do not try to add MEM_Term to an MEM_Static string either. (check-in: 8920dcef1f user: drh tags: trunk)
21:22		Do not try to apply MEM_Term to a MEM_Ephem strings. (check-in: 2a378a6678 user: drh tags: trunk)
20:13		Fix a buffer overread in the fts5_structure virtual table (test code). (check-in: b837aff79c user: dan tags: trunk)
17:05		Simplification to the sqlite3_stmt_explain() implementation. (check-in: dd5eb4c7f7 user: drh tags: trunk)
15:53		SAHPoolUtil.importDb() now accepts either a byte array or ArrayBuffer. (check-in: 3848f04e54 user: stephan tags: trunk)
15:31		Enhancements to the new sqlite3_stmt_explain() interface implementation and documentation. (check-in: dc98ac6b6d user: drh tags: trunk)
2023-07-28
21:38		Fix doc error noted in [forum:/forumpost/11fc7308d5e607f2\|the forum] and a misspelling. (check-in: 6b79cc7dd0 user: larrybr tags: trunk)
20:59		Do not allow the same JSON parse to be input to both arguments to the json_patch() routine. (check-in: 8e781c6742 user: drh tags: trunk)
19:07		Merge the latest trunk enhancements into the wal-shm-exceptions branch. (check-in: c44fb4d065 user: drh tags: wal-shm-exceptions)
19:00		Merge the latest trunk enhancements into the reuse-schema branch. (check-in: b8731493bf user: drh tags: reuse-schema)
18:52		Merge the latest trunk enhancements into the bedrock branch. (check-in: 1d6ded3234 user: drh tags: bedrock)
18:47		Merge the latest trunk enhancements into the wal2 branch. (check-in: c1fa1cb5e0 user: drh tags: wal2)
18:44		Internal JNI binding docs. (check-in: 991c66197e user: stephan tags: jni)
18:43		Merge the latest trunk enhancements into the begin-concurrent branch. (check-in: 7407dda8b4 user: drh tags: begin-concurrent)
18:37		Add the sqlite3_stmt_explain() API. (check-in: 0443c0ef85 user: drh tags: trunk)
18:02		Fix an incorrect file path in ext/jni/README.md (check-in: bcefa2df56 user: stephan tags: jni)
16:12		Minor tweaks to the JSON performance measurement documentation. (check-in: 0bed957e46 user: drh tags: trunk)
15:58		Fix minor typos in the JNI README.md file. (check-in: e21cf2e8f1 user: drh tags: jni)
14:20		Enhancements to the JSON performance testing scripts and instructions to cover the recent optimizations involving updates to large JSON strings that indexed. (check-in: f9213289d0 user: drh tags: trunk)
13:52		JSON performance improvements: (1) Add a cache for large string values on OP_Column to avoid having to extract the string multiple times. (2) Internal JSON caching improvements. (check-in: 771fe35074 user: drh tags: trunk)
12:59		A failed attempt to add a new sqlite3_result_zeroterminated() interface that is a hint to SQLite that a TEXT result does have a zero terminator. The idea is to avoid unnecessary copying of TEXT values. This seems like an unnecessary complication at the moment, but maybe I'll return to this later. Note that this check-in does not work - it is a proof of concept only. (Closed-Leaf check-in: a0de01108c user: drh tags: sqlite3_result_zeroterminated)
11:52		Correct a recently-introduced falsehood in ext/wasm/README.md regarding ssh port forwarding. (check-in: 2a3f3a9cf2 user: stephan tags: trunk)
11:30		Mark an unreachable branch as ALWAYS(). (Closed-Leaf check-in: 8fd06d1151 user: drh tags: json-opt)
10:37		Minor java cleanups recommended by a modern IDE. (check-in: f92a9bbabe user: stephan tags: jni)
10:01		Add Java tests which ensure that xFinal() is called with no aggregate context when the result set is empty. (check-in: 7ac8c66a6b user: stephan tags: jni)
09:54		Tweaks to the Java-side UDF docs. (check-in: 48e0079d8d user: stephan tags: jni)
09:25		More Java docs about making use of the aggregate context. Change the JNI mapping to set the sqlite3_context::aggregateContext member directly, instead of via a superflous setter, because that way is faster. (check-in: 7af0cb998f user: stephan tags: jni)
01:51		More docs and cleanups related to the aggregate UDF state. Correct the OOM check to behave properly if xFinal() is called without a matching xStep(), xValue(), or xInverse(). (check-in: ff53f1ccdc user: stephan tags: jni)
01:19		Add an OOM check to the previous check-in. Minor internal API renaming. (check-in: 6b56e4d62b user: stephan tags: jni)
01:12		Add support making use of sqlite3_aggregate_context() (in a roundabout way) from Java to accumulate state within aggregate and window UDFs. (check-in: 6405749847 user: stephan tags: jni)
00:54		Remove some unnecessary and incorrect code that was mistakenly added in the previous check-in. (check-in: d3f458dcc3 user: drh tags: json-opt)
2023-07-27
23:51		Switch to using jsonParseCached() for json_patch(). (check-in: 2ed9c59e6a user: drh tags: json-opt)
22:53		Reformulate jni tests to not require the -ea jvm flag to enable assert(). (check-in: dc356667a8 user: stephan tags: jni)
22:42		Add locking test for BusyHandler and clear up new -Xlint:jni warnings introduced by the busy-handler binding. (check-in: 7dcde2bfce user: stephan tags: jni)
22:05		Bind sqlite3_busy_handler(). Correct mapping of pointers for, and cleanup of, JNI-level per-db state. (check-in: 524747796a user: stephan tags: jni)
20:32		Replace some www: interwiki references in the JNI readme with their full URLs to make the doc more portable. (check-in: 63ce0c9bdd user: stephan tags: jni)
20:28		If the input JSON to a json function that uses cache comes from an RCStr value, then use that RCStr value in the parse rather than making a copy. (check-in: 509ae9c147 user: drh tags: json-opt)
20:12		Merge trunk into jni branch for compiler warning fixes. (check-in: 0514fd340a user: stephan tags: jni)
20:08		Fix a couple of compiler warnings in fts5_index.c. (check-in: bf71faa2a1 user: dan tags: trunk)
20:02		Initial check-in of JNI (Java Native Interface) bindings for the core C API. (check-in: b5374b9ef5 user: stephan tags: jni)
19:39		The OP_Column opcode caches large column values coming from overflow pages. (check-in: ab1edcc7fe user: drh tags: json-opt)
19:13		Add the contentless_delete=1 option to fts5. For creating contentless tables that support DELETE and REPLACE statements. (check-in: d66b182d2b user: dan tags: trunk)
18:19		Merge trunk enhancements into the json-opt branch. (check-in: 5739a16ad2 user: drh tags: json-opt)
17:50		Dynamically determine whether the wasm.xWrap() argc check can be applied, depending on how the wasm environment exposes its exports. (check-in: fd59226b34 user: stephan tags: trunk)
15:00		Dynamically determine whether the wasm.xWrap() argc check workaround for JSPI is necessary, instead of baking it in to JSPI builds. (Edit: closing jspi branch. Introducing JSPI would require making parts of the C API wrapper async.) (Closed-Leaf check-in: 86bb464f31 user: stephan tags: jspi)
01:38		Accommodate a breaking change in emcc 3.1.44. (check-in: 2c5dd34199 user: stephan tags: trunk)
01:35		Accommodate a breaking change in emcc 3.1.44. (check-in: 4ce3860300 user: stephan tags: jspi)
00:21		Fix a performance regression in JSON associated with generating small snippets of JSON from a larger JSON string. See [forum:/forumpost/15d6bd9cd37202a7\|forum thread 15d6bd9cd37202a7]. (check-in: 837f2907e1 user: drh tags: trunk)

23:22		Reduce the number of memory allocations when parsing JSON. (check-in: 9edd671621 user: drh tags: trunk)
21:53		Minor changes to make coverage testing easier. (check-in: ec8b43382e user: drh tags: trunk)

19:11		Make sure jsonReplaceNode() always leaves the JsonParse in a consistent state even if an error is encountered. (check-in: 01d52232dd user: drh tags: trunk)
18:34		Add a comment describing the contents of the ExceptionInformation[] array for win32 EXCEPTION_IN_PAGE_ERROR exceptions. No changes to code. (check-in: 8e20354242 user: dan tags: wal-shm-exceptions)
18:13		Make sure jsonReplaceNode() always leaves the JsonParse in a consistent state even if an error is encountered. (Closed-Leaf check-in: 29c7b1cbc4 user: drh tags: mistake)
18:11		Initial experimentation with getting JSPI (JavaScript Promise Integration) support working. It builds, but requires disabling func argument count validation checks on sqlite3.wasm.xWrap()-processed exports and it crashes cryptically in wasm when the tests are run. (check-in: 5b178f92f5 user: stephan tags: jspi)
17:51		Add the ".scanstats vm" command to the shell tool. For profiling VM code in SQLITE_ENABLE_STMT_SCANSTATUS builds. (check-in: 0cbec3990d user: dan tags: trunk)
16:41		Improve the output when ".scanstats vm" is enabled. (Closed-Leaf check-in: 7df08fd35e user: dan tags: scanstatus-exp)
14:18		Improved caching and reuse of JSON parses. (check-in: df099ad713 user: drh tags: trunk)
13:17		Change the debugging "json_parse(X)" function so that it shows a more complete description of the JsonParse object on standard output and returns the mimified JSON. Former behavior was to return the text of a decode of the aNode array. (check-in: 1bf85d4e38 user: drh tags: json-opt)
11:53		More comment improvements in json.c. Do not run jsonLookup() following an OOM error. (check-in: cd5fda8c2e user: drh tags: json-opt)
11:43		Improved comments and other cleanup for the changes on this branch. (check-in: bac953a80d user: drh tags: json-opt)
11:41		Remove the batch SQL runner from the JS build's 'all' target, as it's long-since unused and adds noticable build time. Add makefile comments about JSPI. (check-in: b8f708e35d user: stephan tags: trunk)
11:11		Add SAHPoolUtil.getFileNames() method, and tests for it, per [forum:a3da1e34d8\|forum feedback]. Add a test to demonstrate that two SAH pools can coexist so long as they have different names. (check-in: 72dc3f8c32 user: stephan tags: trunk)
11:00		Fix jsonForceRCStr() to also add the NULL terminator. (check-in: 134b01f37f user: drh tags: json-opt)
07:57		Reformulate [907dfc4a7aa1] using awk instead of sed for better cross-platform portability. (check-in: 82ff7cc6a4 user: stephan tags: trunk)
01:15		Merge the latest trunk fixes into the json-opt branch. (check-in: ef4e1664d1 user: drh tags: json-opt)
01:12		Add the concept of an RCStr string - a "Reference Counted String". Use these to keep track of big JSON strings that might need to be used in multiple places at the same time with different lifetimes. Add two different JSON string values to each parse - one with and one without changes. The net result is a large reduction in the number of parses that occur when doing an UPDATE of a indexed JSON field using json_replace() or similar. (check-in: a4c1af616e user: drh tags: json-opt)
01:05		Extend the enhancement to json_set() and json_replace(). Clean up cruft. (Closed-Leaf check-in: 2dbb22c75e user: drh tags: json-opt-rcstr)
00:48		Add the JsonParse.zAlt field to old revised JSON text after a change. Demonstrate that this elminates the need for reparsing after a change by using it in the json_remove() function. This is an incremental check-in containing lots of cruft. (check-in: f930b139d6 user: drh tags: json-opt-rcstr)
2023-07-25
20:26		Clarify ownership of the various objects involved in parsing JSON. (check-in: afe02a398a user: drh tags: json-opt-rcstr)
18:28		Incremental improvements to JSON parsing - trying to fold in the RCStr object. (check-in: 4cb15d934a user: drh tags: json-opt-rcstr)
17:54		Fix a harmless "set-but-not-used" compiler warning in sqlite3session.c. (check-in: 54b3c43fdf user: dan tags: trunk)
17:11		Merge trunk changes into this branch. (Closed-Leaf check-in: 719973d7f5 user: dan tags: fts5-contentless-delete)
16:48		Add extra test for 'deletemerge'. (check-in: bc33cff420 user: dan tags: fts5-contentless-delete)
15:48		Change the name of the fts5 'delete-automerge' option to 'deletemerge'. And add tests for it. (check-in: 1079300db2 user: dan tags: fts5-contentless-delete)
15:43		Fix a minor problem with error reporting in JSON. (check-in: c456e4a899 user: drh tags: json-opt-rcstr)
15:08		Create the new RCStr class of strings and try to use them for JSON storage. (check-in: c1b8725089 user: drh tags: json-opt-rcstr)
13:53		Further tests for 'delete-automerge'. (check-in: ca26c7a37a user: dan tags: fts5-contentless-delete)
12:26		Reformulate a (sed -i) construct in ext/wasm/GNUmakefile to account for Mac's sed -i being different than GNU's. (check-in: 907dfc4a7a user: stephan tags: trunk)
00:13		First attempt to cache modified JSON parses. Does not work. This is an incremental check-in. (Leaf check-in: 075eb09a4f user: drh tags: json-opt-wcache1)
2023-07-24
23:27		It is an error to try to insert a BLOB value into JSON. (check-in: 28c6e964b1 user: drh tags: json-opt)
22:45		Clean up some #defines in json. (check-in: 327fff501e user: drh tags: json-opt)
22:34		Rework the JSON parse structure to facilitate better caching. Passes all tests. (check-in: ecdcb1ded7 user: drh tags: json-opt)
19:13		Add the fts5 'delete-automerge' integer option. A level is eligible for auto-merging if it has a greater than or equal percentage of its entries deleted by tombstones than the 'delete-automerge' option. Default value is 10. (check-in: b314be66b9 user: dan tags: fts5-contentless-delete)
17:59		Incremental progress toward improved caching of parsed JSON. (check-in: f2c0638846 user: drh tags: json-opt)
15:41		Resolve an ES6 module export construct which is incompatible with node.js, as reported in [forum:b9680fa9ad\|forum post b9680fa9ad]. (check-in: 80927c3913 user: stephan tags: trunk)

13:20		Merge the latest trunk enhancements into the wal2 branch. (check-in: b2e56f62ad user: drh tags: wal2)
13:15		Merge the latest trunk enhancements into the begin-concurrent branch. (check-in: 967be041ea user: drh tags: begin-concurrent)
12:59		Update the latest trunk enhancements into the wal-shm-exceptions branch. (check-in: 3187ee3f69 user: drh tags: wal-shm-exceptions)
12:37		Merge the latest trunk enhancements into the json-opt branch. (check-in: 00bfc4918b user: drh tags: json-opt)
2023-07-23
22:14		When writing the filename header in a opfs-sahpool file, ensure that all remaining bytes in that part of the header are zeroed out to avoid the downstream problems reported in [forum:d50ec48a293988a5\|forum post d50ec48a293988a5]. (check-in: c1b080e393 user: stephan tags: trunk)
2023-07-22
19:57		Add the opfs-sahpool sqlite3_vfs implementation to JS, offering an alternative to the other OPFS VFS (with tradeoffs). (check-in: d2e602cda4 user: stephan tags: trunk)
19:47		Integrate contentless delete with auto-merge. (check-in: 85c1589ab1 user: dan tags: fts5-contentless-delete)
16:37		Do not read past the end of a text buffer looking for a zero terminator, as that space might not be initialized. If the buffer is owned, just set the null terminator. This is a better fix for the OSSFuzz-detected use-of-initialized-value problem. (check-in: 931bccb0cc user: drh tags: trunk)
15:21		Fix a harmless use-of-initialized-value warning from OSSFuzz that results from recent large string optmizations. (check-in: 1a6b3dd1c4 user: drh tags: trunk)
2023-07-21
22:28		Performance enhancements for queries using very large string values. (check-in: 3661b9cd98 user: drh tags: trunk)
22:22		Mark an unreachable branch as NEVER(). (Leaf check-in: 414a4d660c user: drh tags: big-function-text)
21:10		Fix fts5 incremental optimization so that it too can handle an index that consists of a single segment with one or more tombstone hash pages. (check-in: e61c9b083f user: dan tags: fts5-contentless-delete)
19:33		Ensure the fts5 'optimize' command correctly rewrites any index that consists of a single segment and one or more tombstone hash pages. (check-in: f4926006b3 user: dan tags: fts5-contentless-delete)
19:17		Fix harmless compiler warning introduced by the previous check-in. (check-in: 06f829e9e5 user: drh tags: big-function-text)
18:38		Avoid a potentially large strlen() in sqlite3DecOrHexToI64(). (check-in: 5413b02bb6 user: drh tags: big-function-text)
18:09		Further improvements to large string handling in relation to JSON. (check-in: 1e5df0aa3d user: drh tags: big-function-text)
15:07		Fix harmless compiler warning about signed/unsigned comparison. (check-in: 75cc3c89ee user: drh tags: big-function-text)
15:01		Multiple optimizations that try to preserve or infer the zero-terminated property of TEXT values. Avoid unnecessary copying of text values destined to become function parameters. All changes help improve performance of doing UPDATEs on large JSON values that are indexed multiple ways. (check-in: d0278cdedf user: drh tags: big-function-text)
11:09		More infrastructure changes towards improving JSON cache performance. Incremental check-in. (check-in: 1955e66cfc user: drh tags: json-opt)

23:25		Minor internal cleanups in JS code. (check-in: 21a2ca9fc4 user: stephan tags: opfs-sahpool)
20:29		Fix some divide-by-zero errors that could occur when handling corrupt tombstone hash records. (check-in: 7567ca0676 user: dan tags: fts5-contentless-delete)
20:09		Avoid an infinite loop that could be entered when dealing with corrupt fts5 tombstone hash pages. (check-in: 69ce2ce035 user: dan tags: fts5-contentless-delete)
17:45		Experimental framework upon which to build a better JSON parse structure that supports cached of modified JSON. All of these changes are tentative and subject to change or removal. Incremental check-in. (check-in: e384163a47 user: drh tags: json-opt)
16:07		Add tests and fixes for the new code on this branch. (check-in: 5aac50e92e user: dan tags: fts5-contentless-delete)
09:06		Filter the OPFS VFSes out of the sqlite3-node.mjs build. Add another level of subdirectory to the sahpool to later enable transparent support of client-provided files under the VFS's root dir. Rework the awkward sahpool-via-oo1 mapping. (check-in: 080a4d0aba user: stephan tags: opfs-sahpool)
2023-07-19
23:02		Performance enhancements to the JSON parser and code generator. (check-in: 0a745897d6 user: drh tags: trunk)
20:23		Revise the new JSON parser performance test to make the test run 25 times longer, and thus provide a more repeatable number. (check-in: bee9e403ae user: drh tags: trunk)
19:23		Describe JSON parser performance testing procedure in test/json/README.md (check-in: c47056e158 user: drh tags: trunk)
18:47		Fix various issues with code added to this branch. (check-in: 8d09011fa2 user: dan tags: fts5-contentless-delete)
17:47		More internal refactoring and docs for opfs-sahpool. (check-in: 64ccf6177a user: stephan tags: opfs-sahpool)
17:46		Update the development-over-ssh docs for the wasm build. (check-in: 500109bd0a user: stephan tags: opfs-sahpool)
17:24		Further improvement to JSON parser performance. (check-in: 144c8ccf6e user: drh tags: json-opt)
15:06		Further performance enhancements to JSON parsing and rendering. Total performance gain for large JSONs so far on this branch is about 11%. (check-in: adb4d6b007 user: drh tags: json-opt)
13:50		Performance optimization for parsing large JSONs that contain lots of text. (check-in: c9fbe0185c user: drh tags: json-opt)
13:31		Major restructuring of opfs-sahpool to improve maintainability and hopefully make it easier to reuse these pieces in the upcoming JSPI-based VFS experiment. (check-in: 534481cd0c user: stephan tags: opfs-sahpool)
12:52		Enhance the JSON parser cache such that it is able to extract lines from the cache and use them for writing, though they then have to be evicted from the cache. This was an experiment in trying to reduce the amount of parsing needed for a big UPDATE, but it does not seem to help any. Retained for reference only. (Closed-Leaf check-in: 2e6fbebc41 user: drh tags: json-write-cache)
11:33		Appearance and legibility improvements for tester1.js. (check-in: 4fd3ed1b64 user: stephan tags: opfs-sahpool)
10:17		Merge the latest trunk enhancements into the sqlite3_stmt_explain branch. (Closed-Leaf check-in: 06eae046c1 user: drh tags: sqlite3_stmt_explain)
09:52		Two minor improvements to sum(), one of which was inspired by [forum:/forumpost/af5be98dbc\|forum post af5be98dbc]. (check-in: a0d3e7571a user: drh tags: trunk)
08:18		Internal refactoring in opfs-sahpool. Move OPFS tests to the end of tester1.c-cpp.js. (check-in: 6bd5a7413d user: stephan tags: opfs-sahpool)
2023-07-18
21:06		Do not use the viewscan optimization on a query that has only a single loop, as the cost adjustments can cause problems for outer queries. Proposed fix for the performance regression reported by [forum:/forumpost/64d36440e473516c\|forum post 64d36440e473516c]. (check-in: 76152ad2ff user: drh tags: trunk)

17:29		Enhance the sqlite3_stmt_explain() interface so that avoids unnecessary reprepare operations. (check-in: 050f773add user: drh tags: sqlite3_stmt_explain)
16:29		Fix memory leak in fts5 introduced by [def41225]. (check-in: 4dcad2db74 user: dan tags: trunk)
16:24		Major restructuring of the opfs-sahpool bits to better support multiple instances per app (each sandboxed from each other). Eliminate the pesky promise resolution race condition when two such instances are loaded in parallel. (check-in: 95e5fa498f user: stephan tags: opfs-sahpool)
15:06		Experimental (untested, non-working) changes that try reduce the number of reprepares generated by sqlite3_stmt_explain(). I think I see an easier way to do this now, so I'm parking this experiment on a branch to pursue the new idea. (Closed-Leaf check-in: c2fba6a632 user: drh tags: sqlite3-stmt-explain-opt1)
13:55		Merge trunk changes with this branch. (check-in: 5f66eb4e26 user: dan tags: fts5-contentless-delete)

17:59		Do not allow the 'delete' command to be used on contentless_delete=1 fts5 tables. (check-in: cc694b8340 user: dan tags: fts5-contentless-delete)
11:47		Merge trunk changes into this branch. (check-in: c4fb2f2ea0 user: dan tags: fts5-contentless-delete)
07:43		Another -DSQLITE_TEMP_STORE=3 to 2 change for the wasm build. (check-in: 5ad8f9987c user: stephan tags: opfs-sahpool)
07:14		sahpool vfs: rename defaultCapacity to initialCapacity, per feedback. (check-in: 2c9c95d087 user: stephan tags: opfs-sahpool)
07:13		Change wasm build's -DSQLITE_TEMP_STORE=3 to -DSQLITE_TEMP_STORE=2, primarily so that clients can optionally shift temp files from memory to OPFS storage. (check-in: 764430e804 user: stephan tags: opfs-sahpool)
2023-07-16
21:07		Remove an extraneous JS script import. (check-in: 5a205b2591 user: stephan tags: opfs-sahpool)

19:20		Doc tweaks only, no code changes. (check-in: 044c28dffd user: stephan tags: opfs-sahpool)
17:51		Add a way to remove the opfs-sahpool's persistent state from OPFS or unlink() an individual file. Doc cleanups. (check-in: 80982daac3 user: stephan tags: opfs-sahpool)
16:52		Move SAH pool configuration options from the library-level config to a config passed to the VFS install routine. Extend and document the PoolUtil object. (check-in: d2ed99556f user: stephan tags: opfs-sahpool)
14:07		speedtest1.js: only install opfs-sahpool if it's provided via --vfs flag, to avoid locking errors in concurrent speedtest1 tabs with other VFSes. Add opfs-sahpool reserveMinimumCapacity(). (check-in: aa94c8abfb user: stephan tags: opfs-sahpool)
12:02		During "opfs" VFS init, check for URL param opfs-disable and, if set, do not install the VFS. Added per forum suggestion to provide a way to help rule out misinteraction between the "opfs" and "opfs-sahpool" VFSes. (check-in: 29905b7a75 user: stephan tags: opfs-sahpool)
11:49		Micro-optimizations in opfs-sahpool. (check-in: 52f23db948 user: stephan tags: opfs-sahpool)

21:08		Minor cleanups in the opfs-sahpool VFS. (check-in: 279e090709 user: stephan tags: opfs-sahpool)
19:08		Correct opfs-sahpool VFS after the pebkac involving the previous speedtest1 runs. Make that VFS explicitly opt-in to avoid certain unfortunate locking situations. (check-in: 41bf1fe31f user: stephan tags: opfs-sahpool)
18:57		Store large tombstone hash tables in multiple database records. Ensure the same hash tables handle rowid 0. (check-in: 4410e60d0c user: dan tags: fts5-contentless-delete)
16:48		Add the experimental sqlite3_stmt_explain(S,E) interface. (check-in: 5683743ddf user: drh tags: sqlite3_stmt_explain)
16:30		speedtest1 JS: only add --memdb flag by default if no --vfs is provided. (check-in: 676ffe6280 user: stephan tags: opfs-sahpool)
11:37		Rename opfs-sahpool removeCapacity() to reduceCapacity(). (check-in: fff68e9f25 user: stephan tags: opfs-sahpool)
11:23		opfs-sahpool VFS now seems to work, in that it runs fine (and blazingly fast) in speedtest1. Add sqlite3.config options for the high-level configurable parts of opfs-sahpool. (check-in: 5d92d5f4d8 user: stephan tags: opfs-sahpool)
01:02		More work on porting the sahpool bits. Revert to random backing-store names because it works better with the capacity-reduction algorithm. (check-in: b4e005fd38 user: stephan tags: opfs-sahpool)
2023-07-14
23:02		Switch opfs-sahpool to use deterministic backing-store file names. Delay VFS registration until after the pool's files are all opened. Fail vfs init if the client's OPFS API has an async FileSystemSyncAccessHandle.close() method (indicating that it's outdated). (check-in: 7c6697eded user: stephan tags: opfs-sahpool)
21:48		Integrate the opfs-sahpool VFS into the JS build and get it loading (but it's still far from functional). (check-in: ef96e6b586 user: stephan tags: opfs-sahpool)
21:17		Initial sketches for an alternate OPFS VFS which uses a pool of pre-opened SyncAccessHandles to bypass the need for a dedicated I/O worker and the COOP/COEP HTTP response headers. Currently completely non-functional. (check-in: a93de9f2a5 user: stephan tags: opfs-sahpool)
21:06		Minor internal cleanups in the OPFS VFS. (check-in: 984d491eb3 user: stephan tags: trunk)
12:21		Minor wasm build cleanups. (check-in: 816b503f09 user: stephan tags: trunk)
2023-07-13

16:33		Get speedtest1 wasmfs variant running again. (check-in: 0f77e031da user: stephan tags: wasmfs-2023)
14:49		Fix an off-by-one error in tests for cells overflowing the end of pages. The error is completely harmless for the default page cache, but might cause false-positive SQLITE_CORRUPT errors in systems that use an application-defined page caches that pack pages tightly together in memory. (check-in: ce6793e954 user: drh tags: trunk)
14:08		Significant surgery on the wasm build on the way to incorporating wasmfs as a first-class build option. (check-in: 215c37fce3 user: stephan tags: wasmfs-2023)

04:54		Minor cleanups in the wasmfs build. (check-in: f64477f210 user: stephan tags: wasmfs-2023)
04:26		Get wasmfs build and its bare-bones test app working again, albeit currently in ES6 mode only. (check-in: 647761ed42 user: stephan tags: wasmfs-2023)
03:46		Replace 'self' with 'globalThis' in some JS test code. (check-in: 53eeffc9b1 user: stephan tags: trunk)
01:51		JS: change the default OPFS VFS journal mode from PERSIST to DELETE, as DELETE is faster in current browsers. (check-in: a061a43e36 user: stephan tags: trunk)
01:48		Remove obsolete ext/wasm/api/sqlite3-wasi.h. (check-in: f661a6e0c1 user: stephan tags: trunk)
2023-07-12
20:24		Avoid a case of an infinite loop in fts5 when dealing with corrupt records. (check-in: 0e801f11cd user: dan tags: fts5-contentless-delete)

2023-07-01
20:21		This check-in adds the use of "long double" to sqlite3FpDecode() which when run on x86 using a compiler that translates "long double" into binary80, causes all legacy tests to pass. But on a system where "long double" is just an alias for "double", some of the tests are still failing. (check-in: ce06982f88 user: drh tags: fp-to-decimal-refactor)
18:33		Reinstate the fpdecode() SQL function for testing, but only when compiled with SQLITE_DEBUG. (check-in: 07eab52e08 user: drh tags: fp-to-decimal-refactor)

23:03		Cleanup and commenting of the new DECIMAL extension code. No functional changes. (check-in: 5124481663 user: drh tags: trunk)
20:28		Enhancements to the DECIMAL extension: (1) If the argument to decimal(X) is a floating point value (or an 8-byte blob), the floating point value is expanded into its exact decimal representation. (2) Function decimal_sci(X) works the same except it returns the result in scientific notation. (3) New function decimal_pow2(N) returns the full decimal expansion of the N-th integer power of 2.

16:48		Change the (undocumented) dtostr() SQL function in the CLI so that it only shows the first 26 significant digits - 10 more digits than are available in a 64-bit double. (check-in: d758859f6a user: drh tags: trunk)
14:49		Add the decimal_sci(X) function to the Decimal extension for showing a decimal value in scientific notation: +D.DDDDDe+DD (check-in: 61d4923913 user: drh tags: trunk)
12:14		CLI enhancements to facilitate SQLite core testing: (1) Add built-in functions strtod() and dtostr() that convert text to floating point and back using C-library routines. (2) Do not disable all of ".testctrl" without --unsafe-testing, but only those subcommands of .testctrl that are actually dangerous. (check-in: 669996a8dd user: drh tags: trunk)
2023-06-28

21:47		Improved comment on the getAndInitPage() in btree.c. No code changes. (check-in: dc468cfdb8 user: drh tags: trunk)
18:12		This is a failed attempt to optimize the usage of the page cache in sqlite3BtreeIndexMoveto() by deferring calls to sqlite3PagerUnref() for child pages of the btree until we are sure those pages will not be reused. The code does not work in two senses: (1) Many tests still fail. (2) The performance gain is less than 2 million cycles and does not seem worth the extra risk and complication.

2023-06-14
13:45		Add SQLITE_DBCONFIG_RANDOM_SCANORDER. This option causes unconstrained table and index scan to happen in a random order, in order to help detect under-constrained queries in applications. Closed because this feature does not add any new capabilities that are not already available with SQLITE_DBCONFIG_REVERSE_SCANORDER, but it does make the behavior non-deterministic, and hence more difficult to test.

20:21		Add the SQLITE_ENABLE_NAN_INF compile-time option which makes the following behavior changes: (1) sqlite3_value_double(NULL) returns NaN, (2) SQLite preserves NaN values rather than converting them to NULL. (3) CAST statements understand "NaN" and "Inf" and make the right conversions.

17:11		Cherrypick the "(X IS [NOT] NULL)" fix from trunk onto branch-3.41. (check-in: 0fc7f7c2a9 user: drh tags: branch-3.41)
16:25		When it is known when preparing a statement that X cannot be NULL or is always NULL, transform the expression (X IS NULL) to integer value 1 or 0 instead of 'true' or 'false'. This is because under some circumstances, "Y IS TRUE" or "Y IS FALSE" may not be equivalent to "Y IS 1" of "Y IS 0".

06:58		Resolve a parallel build timing issue when building sqlite3.c/h from ext/wasm. For the time being, do not add sqlite3_wasm_extra_init.c to fiddle.wasm because it can cause duplicate definitions of extensions which are already built into the shell (a better resolution for this conflict is pending). No longer add sqlite3_wasm_extra_init.c to speedtest1.wasm because it's useless there. (check-in: 75fdd5b83b user: stephan tags: trunk)

2023-03-01
20:44		When flattening a view that is the right operand of a LEFT JOIN always insert the TK_IF_NULL_ROW expression nodes, even for TK_COLUMN expressions, as the TK_COLUMN might be a column from an outer query and hence still need to be NULLed out. (check-in: 371838562a user: drh tags: branch-3.41)
20:23		When flattening a view that is the right operand of a LEFT JOIN, using the optimization of check-in [41c27bc0ff1d3135], always insert the TK_IF_NULL_ROW expression nodes, even for TK_COLUMN expressions, as the TK_COLUMN might be a column from an outer query and hence still need to be NULLed out.

19:39		Add an sqlite3_db_config() option - SQLITE_DBCONFIG_STMT_SCANSTATS - for enabling and disabling the collection of sqlite3_stmt_scanstats() statistics in SQLITE_ENABLE_STMT_SCANSTATUS builds. Collection of statistics is disabled by default. (check-in: 0f5579bef2 user: dan tags: trunk)
18:06		Only use a Bloom filter on an automatic index if one or more of the key columns in the index can take on non-TEXT values. (check-in: 5916705c73 user: drh tags: trunk)
14:28		In the Bloom filter optimization, hash all strings and blobs into the same value, because we do not know if two different strings might compare equal even if they have different byte sequences, due to collating functions. Formerly, the hash of a string or blob was just its length. This could all be improved. Fix for the issue reported by [forum:/forumpost/0846211821\|forum post 0846211821].

12:46		In the LIKE optimization, do not analyze the new virtual WHERE clause terms until both have been added, since they are expected to be consecutive and the analysis might add complementary terms. This fixes a problem caused by [44200596aa943963] and discovered by dbsqlfuzz and recorded as case 7e3b5983727d843b910b2d9ab556e4afcd777cfb. (check-in: d35de3ad3f user: drh tags: trunk)

20:29		Back out the 'txn' enhancement to date/time functions. The duration of a "transaction" is confused and needs to be straightened out prior to moving forward with this change. (check-in: 4a145f0732 user: drh tags: trunk)
19:45		Be careful to maintain the value of 'txn' as long as there are active statements. Withdrawn See the attached Wiki page. (Closed-Leaf check-in: 98d10cb52a user: drh tags: does-not-work)

12:01		Revert the behavior of date/time functions with no arguments so that they once again work like 'now', even while CURRENT_TIMESTAMP and similar work like 'txn'. (check-in: 06180caff0 user: drh tags: txn-date)
11:34		Change the behavior of date-time functions without any arguments (and thus the CURRENT_TIME, CURRENT_DATE, and CURRENT_TIMESTAMP variables) so that they work like 'txn' instead of like 'now'. This is an incompatibility with legacy, but brings SQLite into conformance with all other SQL systems. (check-in: 1ac78be545 user: drh tags: txn-date)

20:45		Due to a coding error, check-in [8efd61e8518594e3] did not actually use just read transactions if the operation is read-only and the SQLITE_MAX_ATTACHED macro is set to 31 or more. This was due to a misuse of the writeMask field of Parse, pointed out by [forum:/forumpost/aa173c18d5\|forum post aa173c18d5]. (check-in: 8760566893 user: drh tags: trunk)
16:16		Add the missing CARRAY_BLOB macro to the carray.h extension header. (check-in: 10bf639cd1 user: drh tags: trunk)
14:11		Add experimental user function unhex(). (check-in: dbe424b5db user: dan tags: unhex-function)
2023-01-22
21:54		Give CLI .version a place in .help output. (check-in: 5f2dfdcc34 user: larrybr tags: trunk)
2023-01-21
16:53		Minor API doc cleanups and JS code simplification. (check-in: f608a3a456 user: stephan tags: trunk)
12:18		Merge trunk into wasi-patches branch. (check-in: 6fc20d75d4 user: stephan tags: wasi-patches)
00:59		Fix a memory leak in the TCL test harness associated with carray. (check-in: 5a316f9fd9 user: drh tags: trunk)
00:19		Fix harmless compiler warnings. (check-in: ded60f5b34 user: drh tags: trunk)
2023-01-20
21:00		Extend the carray extension to allow the use of BLOB values to be bound as an array of "struct iovec" objects. (check-in: e117a03ca6 user: drh tags: trunk)
19:19		Two branches associated with memdb are now always taken (I believe). Tag them with ALWAYS() to verify this. (check-in: 20b9b5aa4f user: drh tags: trunk)
17:50		Ensure that the database encoding cannot be changed while there are statements running. And that the connection is left in a valid state after an obscure OOM within sqlite3_deserialize(). (check-in: a02da71f3a user: dan tags: trunk)
15:13		Add tests for changing the database encoding via RESET_DATABASE/VACUUM. And test that it is not possible to trick another connection with this. (check-in: b869054acb user: dan tags: trunk)
13:34		The json_group_array(), json_group_object(), and fts5_source_id() functions should all be deterministic and innocuous. (check-in: edcb83fa0d user: drh tags: trunk)
2023-01-19
18:16		Fix numbering issue in and remove duplicate test from windowB.test. (check-in: fa10e561f5 user: dan tags: trunk)
2023-01-18
17:39		Emit sqlite3-api.(m)js during the JS build process, which are the JS APIs without the Emscripten/wasm-loading parts. They are hypothetically useful for arbitrary build environments/toolchains but have notable caveats related to the wasm imports, as elaborated on in the makefile. (check-in: 966b55c513 user: stephan tags: trunk)
2023-01-17
19:34		Fix another issue with very large compressed LSM databases. (check-in: d71154265a user: dan tags: trunk)
19:00		Change an now unreachable testcase() into an assert(). (check-in: 517b2c4c4e user: drh tags: trunk)
18:40		Fix harmless compiler warnings in the CLI. (check-in: 7cf282d307 user: drh tags: trunk)
15:46		Update virtual tables json_each and json_tree so that adding "ORDER BY rowid" to a query does not require an external sort. (check-in: ce18f0ed68 user: dan tags: trunk)
13:33		Add test cases to confirm that the schema parsing quirk in which an ON CONFLICT clause is accepted and ignored on table CHECK constraints but raises an error on column CHECK constraints. We want to continue supporting this harmless quirk to avoid breaking legacy applications and databases that accidentally use it. (check-in: 92b6a9cd0f user: drh tags: trunk)
2023-01-16
21:49		Cause .clone to not trip over sequence table as reported at [forum:/forumpost/71ff9e6c4c\|forum post 71ff9e6c4c]. (check-in: b44d04f7b0 user: larrybr tags: trunk)
18:13		In the CLI, create our own private version of strncpy() to work around false-positive compiler warnings from Alpine Linux. (check-in: 83f21285fe user: drh tags: trunk)
2023-01-14
19:53		Omit the long-disused FTS1 and FTS2 implements from the active source tree. The code will persist forever in the source repository, but there is no point in carrying it around in the latest tarballs where it is never used. (check-in: 2bb50d5aed user: drh tags: trunk)
19:36		Add OOM check, per tip at [forum:/forumpost/933479b2d5\|forum post 933479b2d5] (Leaf check-in: c66c7734fe user: drh tags: branch-3.40)
19:27		Add OOM check, per tip at [forum:/forumpost/933479b2d5\|forum post 933479b2d5] (check-in: eda84dcffe user: larrybr tags: trunk)
19:09		Doc-only fix, per [forum:/forumpost/0cfaf6876b\|forum post 0cfaf6876b] (check-in: eac135fd6a user: larrybr tags: trunk)
2023-01-13
20:49		Fix another lsm compression-mode bug. (check-in: f9fafc9413 user: dan tags: trunk)
19:32		In expression nodes of type REGISTER with sub-type COLUMN, ensure that the iColumn field is set correctly, as otherwise the "IS NULL" operator might be incorrectly optimized. Fix for the problem described by [forum:/forumpost/d010a26798915b53\|forum post d010a26798915b53]. (check-in: 76b440c588 user: drh tags: branch-3.40)
19:29		In expression nodes of type REGISTER with sub-type COLUMN, ensure that the iColumn field is set correctly, as otherwise the "IS NULL" operator might be incorrectly optimized. Fix for the problem described by [forum:/forumpost/d010a26798915b53\|forum post d010a26798915b53]. (check-in: 0819a1869a user: drh tags: trunk)
19:00		Fix an error in debugging output discovered while working on the problem with RETURNING reported by [forum:/forumpost/d010a26798\|forum post d010a26798]. (Leaf check-in: 3ae9127f15 user: drh tags: returning-is-null-fix)
18:20		Add missing "const" on variables in recent RBU fixes. (check-in: 9b8dcd7905 user: drh tags: trunk)
15:54		Enhance query planning so that it check for sqlite3_interrupt() calls and periodically invokes the progress handler callback (if any) during long query analyses. (check-in: bd8fa10e59 user: drh tags: trunk)
15:31		Update documentation for sqlite3_progress_handler(). (Closed-Leaf check-in: 41b4c407b7 user: drh tags: progress-during-prepare)
11:31		Remove an incorrect legacy assert(). (check-in: 3006b3b32f user: drh tags: progress-during-prepare)
2023-01-12
20:36		Reduce the frequency of calls to sqlite3ProgressCheck(). (check-in: 795aca4a26 user: drh tags: progress-during-prepare)
19:51		Fix sqlite3_prepare() so that it only invokes the progress handler on every N-th call to sqlite3ProgressCheck(), where N is the progress handler step count. Also fix faulty asserts exposed by the ability to interrupt in the middle of sqlite3_prepare(). (check-in: 0546165159 user: drh tags: progress-during-prepare)
19:43		Merge latest trunk changes, including fixes for RBU pass-through mode, with this branch. (check-in: deb26d034b user: dan tags: reuse-schema)
19:28		Do not attempt to run new test file rbupass.test if the "demo" VFS is not available. (check-in: c5d958eb94 user: dan tags: trunk)
19:11		Avoid crashing when using an RBU VFS with a version 1 parent VFS. (check-in: d149772d18 user: dan tags: trunk)
17:13		When deleting any old OAL file before starting an RBU update or vacuum, use the same VFS as will be used for the target database, even if this is not the system default. (check-in: 5a86c6cb1f user: dan tags: trunk)
13:25		Attempt to provide a mechanism to do early termination of long-running statement preparation by invoking the progress handler at strategic points during sqlite3_parpare(). This experiment shows that sqlite3_prepare() might leave the resulting prepared statement uninitialized following an interrupt. (check-in: 79636f2d80 user: drh tags: progress-during-prepare)
2023-01-11
22:45		Merge trunk into wasi-patches branch and add missing yes/no result to the configure script's output for the --with-wasi-sdk=PATH test. (check-in: adc0ede0a4 user: stephan tags: wasi-patches)
20:52		Fix duplicate semicolon in btreeInt.h. [forum:/forumpost/8db1711ca2\|Forum post 8db1711ca2] (check-in: 7526c46632 user: drh tags: trunk)
17:59		Fix a false-positive in the out-of-range jump detection logic that was added as part of RIGHT JOIN. (check-in: ab5bcb91cd user: drh tags: trunk)
17:50		If OP_Rewind has P2 of zero, that is an assertion that the table is never empty. This fixes a false-positive in the out-of-subroutine jump detection logic added in version 3.39.0, and which was causing the assertion on the previous check-in. (Closed-Leaf check-in: 33fd9997eb user: drh tags: code-generator-20230111)
16:44		Add an assert() to the byte-code engine that goes off if the OP_Halt opcode is invoked with SQLITE_INTERNAL. This causes the RIGHT JOIN error "Opcode jumps to ... which is outside the subroutine ..." to fail immediately, causing it to come more readily to tester's attention. There is at least one testcase in test/fuzzdata8.db that asserts due to this change. (check-in: b8f9944142 user: drh tags: code-generator-20230111)
16:25		Fix problems with compressed LSM databases larger than 2GiB. (check-in: f884224578 user: dan tags: trunk)

16:02		Fix another 64-bit offset problem in lsm. (Closed-Leaf check-in: 1f3d0bdc20 user: dan tags: lsm-compress-fixes)
00:27		Add a new sqlite3_is_interrupted() interface that can be used by long-running app-defined functions and similar to see if they need to exit early due to an sqlite3_interrupt() call. (check-in: d030f34136 user: drh tags: trunk)
2023-01-10
19:57		When computing the datatypes for columns in a view, use the same datatype name as the underlying table if such is available and is consistent with the computed affinity of the column. [forum:/forumpost/7fb1fe9dcf310ef5\|Forum thread 7fb1fe9dcf310ef5]. (check-in: 497a98363f user: drh tags: trunk)
15:07		Fix handling of unix paths that contain ".." components such that "/" is considered its own parent directory. [forum:/forumpost/caa46bd1f2f2a255\|Forum thread caa46bd1f2f2a255]. (check-in: b829dd1b97 user: dan tags: trunk)
14:33		Improvements to the SQLITE_DIRECTONLY documentation. (check-in: b277ba40a8 user: drh tags: trunk)
14:31		Fix handling of unix paths that contain ".." components such that "/" is considered its own parent directory. (Closed-Leaf check-in: 3c6cadb396 user: dan tags: unix-path-fix)
2023-01-09
21:10		Fix some problems with large, compressed, lsm databases. (check-in: 956e985ff9 user: dan tags: lsm-compress-fixes)
18:42		Clarify help for .quit. (check-in: 8004a2b743 user: larrybr tags: trunk)
12:01		Fix JSON functions so that they work correctly under PRAGMA trusted_schema. [forum:/forumpost/c88a671ad083d153\|Forum thread c88a671ad083d153]. (check-in: 51a5d83c42 user: drh tags: trunk)
2023-01-07
22:28		Doc-only update, sqlite3_preupdate_hook() return (check-in: 2da51d7e1b user: larrybr tags: trunk)
13:40		Account for read-only connections on LSM databases with non-default block or page sizes. (check-in: 3a2075b089 user: dan tags: trunk)
2023-01-05
14:41		Changes a testcase() into an assert() due to the [e58bba93717cd6ff] change. (check-in: a6251d7289 user: drh tags: trunk)
13:55		Remove the unused sqlite3IsMemdb() routine, to avoid a harmless compiler warning. (check-in: 4f512a39af user: drh tags: branch-3.40)
13:41		Fix a problem with applying integer affinity to a MEM_IntReal value. [forum:/forumpost/d270125fae\|Forum post d270125fae]. (check-in: d28d9398a5 user: drh tags: branch-3.40)
13:35		Fix a problem with applying integer affinity to a MEM_IntReal value. [forum:/forumpost/d270125fae\|Forum post d270125fae]. (check-in: e58bba9371 user: dan tags: trunk)
01:32		Increase the version number to 3.40.2. (check-in: 43375ef8a7 user: drh tags: branch-3.40)
01:29		In the zipfile extension (which is not part of the SQLite amalgamation, but which is included in the CLI by default) ensure that fopen() is not invoked using a NULL filename. Fix for the issue reported by [forum:/forumpost/d1c96a9032e564f8\|forum post d1c96a9032e564f8]. (check-in: e4de577757 user: drh tags: branch-3.40)
