| 17:05 | Add new interfaces sqlite3_result_pointer(), and sqlite3_value_pointer() and use them to transfer the eponymous FTS3 column pointer to the snippet() and offsets() routines. Cherrypick from commit [8201f4e1] on branch-3.18. (check-in: 553a923c82 user: dan tags: branch-3.19) | |

| 07:49 | Fix a problem in test script thread001.test causing a spurious "-1 files were left open" error when run separately. Cherrypick of [1774f1c3b]. (check-in: 6cf8172d94 user: dan tags: branch-3.19) | |
|
2018-03-06
| ||
| 11:49 | Avoid running a couple of tests in crash8.test that depend on the presence of the journal file if running on an F2FS file-system that does not require a journal file. Cherrypick of [797e02e0]. (check-in: eeedfc74d2 user: dan tags: branch-3.19) | |
|
2018-02-02
| ||
| 08:14 | In SQLITE_ENABLE_BATCH_ATOMIC_WRITE builds on F2FS file-systems, invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE if an SQLITE_FCNTL_COMMIT_ATOMIC_WRITE call fails. Also, do not use an atomic transaction to create the initial database. This is because if an error occurs while writing to the db file, any changes to the file-size do not seem to be rolled back automatically. The only time this matters is when the file was 0 bytes in size to start with. Cherrypick of [b3122db154]. (check-in: 22a228edad user: dan tags: branch-3.19) | |
| 08:08 | Update a couple of test scripts so that they work on F2FS file-systems that support atomic transactions. Cherrypick of [49e58e645e]. (check-in: 1b39467927 user: dan tags: branch-3.19) | |
|
2018-01-13
| ||
| 14:07 | Fix a typo in test file crash8.test. (check-in: 4951d91d40 user: dan tags: branch-3.19) | |
| 13:21 | Fix various problems in test scripts preventing "make test" from passing on F2FS file-systems with the "atomic-write" feature. Cherrypick of [56d93d07]. (check-in: 6a296d4d4d user: dan tags: branch-3.19) | |

| 13:22 | Use batch atomic writes when running on a recent F2FS filesystem, if compiled with SQLITE_ENABLE_BATCH_ATOMIC_WRITE. (check-in: 2dd0c77d54 user: drh tags: branch-3.19) | |
| 13:11 | Move the generation of output column names earlier, to right after name resolution and before query transformations such as flattening. This prevents the names from getting mangled by query transformations, and obviates hacks in the query flattener that attempt to work around the name mangling. The resulting code is smaller and faster and gives more consistent output. This is a fix for ticket [de3403bf5ae5f72ed] and a cherry-pick of check-in [09834279aeca3bda] (check-in: 499942b3ee user: drh tags: branch-3.19) | |
| 12:19 | Correctly handle an "INTEGER PRIMARY KEY UNIQUE" column in a WITHOUT ROWID table. This is a fix for ticket [bc115541132dad136], cherry-picked from check-in [5216bfb73f1a49bdd8] (check-in: 322a2ede6d user: drh tags: branch-3.19) | |
| 12:07 | Increase the version number to 3.19.4 (check-in: b77f297d38 user: drh tags: branch-3.19) | |
| 12:04 | Merge further enhancements to the batch-atomic-write subsystem. (Leaf check-in: 4be4265d74 user: drh tags: batch-atomic-write-3.19) | |
|
2017-07-28
| ||
| 02:02 | Backport of all batch-atomic-write changes through check-in [67bad7fb9b] (check-in: def55027b1 user: drh tags: batch-atomic-write-3.19) | |
|
2017-07-27

|
2017-07-15
| ||
| 10:44 | Add new interfaces sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer() used to safely move pointer values through SQL without exposing underlying memory address information. (Leaf check-in: d6a44b352d user: drh tags: branch-3.17) | |
|
2017-07-14

|
2017-07-13

|
2017-07-07
| ||
| 22:39 | Fix test cases in wal2.test due to the fact that Darwin checks to see if the SHM file is writable before attempting to open in read/write. (check-in: 6b618b18f7 user: drh tags: apple-osx) | |
| 20:33 | Avoid even trying to open a SHM file read/write in WAL mode if we know that the file is read-only. This avoids scare security log messages. (check-in: d9d9278140 user: drh tags: apple-osx) | |
| 19:22 | Fix typos in Win32 VFS for lsm1. (check-in: 0961ec873b user: mistachkin tags: trunk) | |

| 17:57 | Fix the usleep() macro in the Win32 test code for lsm1. (check-in: 63599fa524 user: mistachkin tags: trunk) | |
| 17:43 | Add new PRAGMAs: "function_list", "module_list", and "pragma_list". All are enclosed within #ifdef SQLITE_INTROSPECTION_PRAGMAS. The compile-time option is not on ctime.c yet, since these are still experimental and one can always test "PRAGMA pragma_list" and see whether or not it returns an empty set. (check-in: e0b6ae92ad user: drh tags: trunk) | |
| 17:33 | Add the "Pragma_list" pragma. Put all three pragmas created on this branch inside of #ifdef SQLITE_INTROSPECTION_PRAGMAS. (Closed-Leaf check-in: 2f3c3781ef user: drh tags: list-pragmas) | |

| 16:12 | Have this branch maintain an in-memory hash-table of old pages for read-only MVCC clients. There is no way to access it yet. (check-in: a3a9a2e189 user: dan tags: server-process-edition) | |
| 16:09 | In lsmtest, use an empty string instead of ":memory:" when requesting a temporary database from SQLite. This prevents other test code from trying to unlink() ":memory:", which fails on win32. (check-in: 281ad505d7 user: dan tags: trunk) | |
| 16:07 | Remove a block from the Win32 VFS for lsm1 that is now superfluous. (check-in: db4a41408e user: mistachkin tags: trunk) | |

| 14:26 | Merge recent enhancements from trunk. (check-in: 73d0fc027d user: drh tags: bind-pointer) | |

| 11:49 | Very slightly smaller and faster sqlite3WalkSelect(). (check-in: 9bc65635b2 user: drh tags: trunk) | |
|

| 18:52 | Change the sqlite3_namelist() interface to return a pointer to an array of pointers to strings, and to avoid duplicates. (check-in: 7029111044 user: drh tags: experimental-namelist) | |
| 18:25 | The sqlite3_namelist() routine now works for all name types. (check-in: e41d62175b user: drh tags: experimental-namelist) | |
| 17:36 | Initial implementation of a highly experimental interface for listing all keywords and symbolic names for an SQLite database connection. (check-in: 04ef6783a5 user: drh tags: experimental-namelist) | |
| 16:33 | Change the (machine-generated) keywordhash.h file to increase the scope of the tables used for keyword matching, so that the tables are accessible to functions other then keywordCode(). (check-in: c5ed5ebdf6 user: drh tags: trunk) | |
| 13:51 | More compact implementation of the typeof() SQL function. (check-in: efb4aab0ca user: drh tags: trunk) | |
