| ||
| 00:29 | In the push-down optimization, do not substitute columns that have previously been identified as being constant by the propagate-constants optimization. Fix for ticket [51166be0159fd2ce]. Also, avoid factoring out constant expressions on the LHS of an IN(...) operator, as the IN(...) operation may affect the affinity of these values. Fix for [fd1bda016d1]. (Leaf check-in: 43612157f8 user: drh tags: branch-3.31) | |
|
2020-04-03

| 20:14 | Restore an #if block inadvertently removed via check-in [9c77bfe41e]. (check-in: bf6bcfc16e user: mistachkin tags: branch-3.31) | |
| 13:39 | Do not suppress errors when resolving references in an ORDER BY clause belonging to a compound SELECT within a view or trigger within ALTER TABLE. Fix for ticket [a10a14e9b4ba2]. Also, in the event of a semantic error in an aggregate query, early-out the resetAccumulator() function to prevent problems due to incomplete or incorrect initialization of the AggInfo object. Fix for ticket [af4556bb5c285c08]. (check-in: b64674919f user: drh tags: branch-3.31) | |
| 13:29 | Fix a case when a pointer might be used after being freed in the ALTER TABLE code. Fix for [4722bdab08cb1]. (check-in: 52f800fa93 user: drh tags: branch-3.31) | |
|
2020-03-10
| ||
| 19:23 | Prevent the read-only expressions held in the schema from being passed down into code generating subroutines where they might be changed. Pass a copy of the expression instead. (check-in: 2b750b0f74 user: drh tags: branch-3.31) | |
|
2020-02-27
| ||
| 12:33 | Backport the change that allows the filename passed into the xFullPathname to be used as an argument to sqlite3_uri_parameter(). (check-in: 9c77bfe41e user: drh tags: branch-3.31) | |
|
2020-02-06
| ||
| 11:02 | Fix a 4 byte OOB read in test_multiplex.c. (check-in: 6279f69f0f user: dan tags: branch-3.31) | |
|
2020-02-01
| ||
| 14:29 | Fix a problem in sqlite3CodecQueryParameters() that was introduced by the query parameter encoding changes for the 3.31.1 release. (check-in: 1240ee4f6f user: drh tags: apple-osx) | |
| 13:30 | Fix a problem in sqlite3CodecQueryParameters() that was introduced by the query parameter encoding changes for the 3.31.1 release. (check-in: cc65ca5412 user: drh tags: branch-3.31) | |
| 00:08 | Merge version 3.31.1 (check-in: d250d085fa user: numist tags: apple-osx) | |
|
2020-01-28
| ||
| 18:09 | Reinstate the optimization of converting "a IN (C)" into "a=C" but only if C is a constant. If the RHS is a table column, the complications of managing affinity and collations become too involved to mess with. (check-in: 8ac26a23d7 user: drh tags: trunk) | |
| 16:55 | Fix a 4 byte OOB read in test_multiplex.c. (check-in: 912148913c user: dan tags: trunk) | |
| 15:02 | Minor change for compatibility with the s390 architecture. (check-in: 04885763c4 user: drh tags: trunk) | |
|
2020-01-27
| ||
| 19:55 | Version 3.31.1 (check-in: 3bfa9cc97d user: drh tags: trunk, release, version-3.31.1) | |
| 17:09 | Update the version number to 3.31.1. (check-in: 6fb9a8fb85 user: drh tags: trunk) | |
| 14:40 | Revise the layout of filenames in the Pager object so that it is unchanged from prior versions. It turns out that some important 3rd-party software does questionable pointer manipulations on those filenames that depend on that legacy layout. Technically, this is a misuse of SQLite by the 3rd-party software, but we want to avoid unnecessary breakage. (check-in: 34ab760689 user: drh tags: trunk) | |
|
2020-01-23
| ||
| 15:00 | Fix typos in the sqlite3ext.h header file that prevent some newer APIs from being accessed from loadable extensions. (check-in: 14331989fc user: drh tags: trunk) | |

|
2020-01-22
| ||
| 23:08 | Fix a NEVER() macro that can be true if compiled with SQLITE_ENABLE_UNKNOWN_SQL_FUNCTION. Ticket [b985f0bd1636d9bc] (check-in: 9f0f5d593a user: drh tags: trunk) | |
| 21:12 | Merge version 3.31.0 (check-in: 3bb267deb1 user: drh tags: wal2) | |
| 20:36 | Merge version 3.31.0 (check-in: 0eae87ad11 user: drh tags: apple-osx) | |

| 16:31 | Update test file exclusive.test so that it works with the "journaltest" permutation. (check-in: 4daf94d833 user: dan tags: trunk) | |
| 16:23 | Fix a problem with using views in SQLITE_OMIT_VIRTUAL_TABLE builds. Also some test case fixes required for the same builds. (check-in: 934ee8bdb4 user: dan tags: trunk) | |
| 15:01 | Fix a case in fts3auto.test that fails for SQLITE_DISABLE_FTS4_DEFERRED builds. (check-in: d241055ead user: dan tags: trunk) | |
| 14:42 | Fix an assert() that could fail in SQLITE_MUTATION_TEST builds following an error in a query that uses CTEs. (check-in: c7e29458a7 user: dan tags: trunk) | |
| 13:40 | Fix a problem in the userauth extension causing it to occasionally set "PRAGMA count_changes" (and some others) to true. (check-in: 3a62f64222 user: dan tags: trunk) | |
| 12:29 | Fix the series.c and spellfix.c extensions to use SQLITE_VTAB_INNOCUOUS correctly. Fix the documentation on sqlite3_vtab_config() to take into account SQLITE_VTAB_INNOCUOUS and SQLITE_VTAB_DIRECTONLY. (check-in: 9265cb7f02 user: drh tags: trunk) | |
| 01:45 | Improvements to the autoconf TEA Makefile for MSVC. (check-in: cffcf12f03 user: mistachkin tags: trunk) | |
|
2020-01-20
| ||
| 14:42 | In the fuzzcheck test program, reduce the default expression depth limit from 1000 to 500 to avoid stack-overflow problems when running stress tests using clang ASAN. (check-in: 63d886f4ce user: drh tags: trunk) | |
|
2020-01-19
| ||
| 20:37 | Enhancement to the CLI to allow the ".parameter init" command to work even if defensive mode is turned on. (check-in: 4d46255096 user: drh tags: trunk) | |
|
2020-01-18
| ||
| 23:52 | Documentation improvements. (check-in: 535afe1509 user: drh tags: trunk) | |
| 22:20 | In the TCL interface, add the ability to change the SQLITE_DBCONFIG_TRUSTED_SCHEMA setting using the "db config" method. (check-in: 1accfa8cf0 user: drh tags: trunk) | |
| 21:34 | Allow non-deterministic function in CHECK constraints. It turns out that PostgreSQL, MySQL, and SQLServer all allow this. We should not be the the exception. Ticket [830277d9db6c3ba1] (check-in: 8c8ce526ad user: drh tags: trunk) | |
| 19:46 | Do not use memcpy() of zero bytes when initializing a pager. This avoids a warning. (check-in: cca437788e user: drh tags: trunk) | |
| 19:07 | Disable a redundant test case that uses a very large stack, and hence is unable to run with -fsanitize=undefined,address. (check-in: 3c63f68e12 user: drh tags: trunk) | |
| 19:02 | Fix harmless compiler warning seen with MSVC. (check-in: cd0437ba5b user: mistachkin tags: trunk) | |
| 14:50 | Add extra front margin to the fake empty filename returned by sqlite3PagerFilename() for an in-memory or TEMP database. (check-in: fee945671a user: drh tags: trunk) | |
| 13:53 | Fix the VDBE so that it correctly handles the sequence of operations OP_OpenEphemeral, OP_OpenDup, OP_OpenEphemeral, and OP_OpenDup in that order on the same cursor. (check-in: a1be6ee018 user: drh tags: trunk) | |
|
2020-01-17
| ||
| 23:27 | Fix a typo in a comment. No code changes. (check-in: 4363f69c3a user: drh tags: trunk) | |
| 21:12 | The compress() function should not be deterministic since the same input can have multiple possible compressed outputs. The uncompress() function, on the other hand, is deterministic. (check-in: 84f314902c user: drh tags: trunk) | |
| 19:14 | Fix #ifdefs so it compiles cleanly with all SQLITE_OMIT compile-time options. Update compile-time option testing. (check-in: 7584e4b649 user: drh tags: trunk) | |
| 16:47 | Improved rounding in the 'unixepoch' feature of the date and time functions. (check-in: c9abf1bd2d user: drh tags: trunk) | |
| 15:45 | Update test script instrfault.test to account for the fact that bound blob values cast to text values are now intepreted using the text encoding of the database, instead of always as utf-8. (check-in: 4d6cb28811 user: dan tags: trunk) | |
| 11:18 | Fix a case in "fuzz.test" that could fail, as non-deterministic functions may no longer appear in CHECK constraints. (check-in: a370871e21 user: dan tags: trunk) | |
|
2020-01-16
| ||
| 17:53 | New testcase() macros in select.c, for coverage of the change from two check-ins ago. (check-in: 52206488f3 user: drh tags: trunk) | |
| 16:32 | Add the SQLITE_FCNTL_CKPT_DONE file-control for the use of custom VFSs. (check-in: 3cc39e5069 user: dan tags: trunk) | |
| 16:12 | Do not allow the constant-propagation optimization to apple to ON/USING clause terms as it does not help and it might cause downstream problems. (check-in: 1bc783da63 user: drh tags: trunk) | |
| 12:25 | Fix an SQL syntax error in the comment on the omit-left-join optimization. No changes to code. (check-in: 86b5e5a20e user: drh tags: trunk) | |
| 11:51 | Clean up the definitions of the TERM_ constants in the code generator. Formatting only - no logic changes. (check-in: af06f80a59 user: drh tags: trunk) | |
|
2020-01-15
| ||
| 16:20 | Do not allow the "PRAGMA encoding" statement to change the database encoding if TEMP content exists, or content in any other attached database. Formerly, encoding changes were allowed if just the main database file was empty. Ticket [a08879a4a476eea9]. (check-in: 03b003c988 user: drh tags: trunk) | |
| 14:11 | Merge recent enhancements and fixes from trunk. (check-in: 35eae71a4d user: drh tags: wal2) | |
| 12:49 | Merge all recent enhancements and fixes from trunk into the apple-osx branch. (check-in: dadedf41c7 user: drh tags: apple-osx) | |
|
2020-01-14
| ||
| 16:50 | Fix the urifuncs.c extension (used for testing and debugging only) so that the sqlite3_filename_database() SQL function and its siblings correctly handle an invalid schema name passed in as the argument. (check-in: 3d7434a9d8 user: drh tags: trunk) | |
| 16:39 | Remove an ALWAYS on a branch for improved database corruption detection in btree.c:freeSpace(). Test case found by dbsqlfuzz. (check-in: 54bf048119 user: drh tags: trunk) | |
| 16:33 | Add the new noop_nd() debugging function to the noop.c extension. (check-in: 72911fb1b0 user: drh tags: trunk) | |
| 13:24 | For the showdb utility program, more accurate detection of when the database is in autovacuum mode for the "pgidx" subcommand. (check-in: 9ce2192b81 user: drh tags: trunk) | |
| 13:13 | Fix a minor typo on a comment in the CLI implementation. (check-in: db4fb3503c user: drh tags: trunk) | |
| 00:52 | Improvements to sqlite3_open_v2() documentation. (check-in: 4c4fd62a09 user: drh tags: trunk) | |
|
2020-01-13
| ||
| 15:25 | More documentation updates. No code changes. (check-in: a684d4ef08 user: drh tags: trunk) | |
| 13:33 | Documentation updates. No changes to code. (check-in: cc0e0aa3a7 user: drh tags: trunk) | |
|
2020-01-12
| ||
| 22:38 | Better than removing the incorrect assert() is to change it into a testcase() together with a comment indicating where an appropriate test case can be found, and the ticket that provoked the change. Ticket [614b25314c766238] (check-in: 3e3c60d812 user: drh tags: trunk) | |
| 22:25 | Change the zipfile virtual table so that the xBestIndex method gives a reasonable cost estimate even if no filename is specified. The missing filename error continues to be raised in the xFilter method. Meanwhile, the more reasonable cost estimate avoids unnecessary wierdness in the query planner. (check-in: 0e468aa6de user: drh tags: trunk) | |
| 22:20 | Remove an incorrect assert(). Fix for ticket [614b25314c766238] (check-in: 6a999c5aa0 user: drh tags: trunk) | |
|
2020-01-11
| ||
| 21:08 | New apis: sqlite3_filename_database(), sqlite3_filename_journal(), and sqlite3_filename_wal(). Also sqlite3_uri_key(). And the other sqlite3_uri functions now work using the journal or wal filename in addition to the database file. And the sqlite3_db_filename() result is guaranteed to work as an argument to the sqlite3_uri functions. (check-in: fd7bcc5352 user: drh tags: trunk) | |
| 20:27 | Minor changes for consistency between sqlite3_filename_wal() and sqlite3_filename_journal(). (Closed-Leaf check-in: 9a70ff43a7 user: drh tags: enhanced-uri) | |
| 16:08 | Redesign for better legacy compatibility. Add the sqlite3_uri_key() interface. (check-in: bcb43d11c4 user: drh tags: enhanced-uri) | |
|
2020-01-10
| ||
| 18:05 | Rearchitect the way in which filenames are stored in the Pager object so that the sqlite3_uri_parameter() interface will work from journal and WAL filenames too. This check-in implements the central idea, and compile and runs somewhat, but crashes on an extended test. (check-in: 2ae77bd233 user: drh tags: enhanced-uri) | |
| 01:05 | Fix to the register validity tracking logic in debug builds. No impact on release builds. (check-in: 0a500da6aa user: drh tags: trunk) | |
