| 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) | |
| 15:33 | More restrictions on changes to shadow tables when in defensive mode. (check-in: b302b260ca user: drh tags: branch-3.28) | |
| 15:24 | Validate the type, name, and tbl_name fields of the sqlite_master table when loading the schema, unless writable_schema is engaged. (check-in: 3d13fbf248 user: drh tags: branch-3.28) | |
| 14:56 | Do not allow shadow tables to be dropped in defensive mode. (check-in: ad1f760f16 user: drh tags: branch-3.28) | |
| 14:30 | Import the 3.31.0-beta FTS3/4 code directly into the 3.28 branch, thus providing 3.28 with all the latest 3.31 fixes. FTS3 has not been enhanced to use any core functionality that was not already available in 3.23, so no modifications were made to FTS3 sources for this import. (check-in: be4269c624 user: drh tags: branch-3.28) | |
| 14:18 | Import all FTS3/4 enhancements and fixes that exist on the latest trunk (3.31.0-beta) that do not require extensive change to the SQLite core into the 3.22 branch. Basically, the 3.31.0 FTS3 sources are copied into 3.22.0, with minor changes to work around core enhancements that are not available in 3.22.0. (Leaf check-in: cbcbb1e5a9 user: drh tags: branch-3.22) | |
| 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) | |

| 20:19 | Disable the xfer-optimization if the two tables have the same root page due to schema corruption. (check-in: f31b3bd2a6 user: drh tags: trunk) | |
| 20:06 | Fix another corruption related crash in fts5. (check-in: 4538d9afe4 user: dan tags: trunk) | |
| 19:33 | Add the SQLITE_ENABLE_EARLY_CURSOR_CLOSE compile-time option which causes read cursors to be closed after their usefulness ends during a two-pass UPDATE. (check-in: 7def6c8edd user: drh tags: trunk) | |
| 19:11 | Fix a buffer overwrite that could occur when running an fts5 prefix query against a corrupt database. (check-in: 3910b5639d user: dan tags: trunk) | |
| 17:39 | Fix problems with joining two or more fts5_vocab tables that access the same underlying fts5 table. (check-in: 49956395e1 user: dan tags: trunk) | |
| 15:47 | Sync up with the latest enhancements on trunk. (check-in: 475a179a27 user: drh tags: apple-osx) | |
| 15:40 | Revamp the SrcList allocator routines to be methods of Parse instead of being methods of the "sqlite3" object, so that they can leave better error messages when the SrcList object grows too large. (check-in: df08d472b0 user: drh tags: trunk) | |
| 14:34 | Limit the size of SrcList objects to 200 entries (compile-time configurable using -DSQLITE_MAX_SRCLIST=n). The maximum number of tables in a join has always been 64, so this is not a real constraint on capability. Limiting the size of a SrcList prevents DOS attacks (discovered by OSSFuzz) using crazy nexted CTE joins. (check-in: 7cac614d5d user: drh tags: trunk) | |
| 04:40 | Fix a corner-case for the logic that cause an insert of a NULL into an INTEGER PRIMARY KEY column to be converted into a valid integer key, when the NULL results from a CASE expression that lacks an ELSE clause. (check-in: 9a425051e7 user: drh tags: trunk) | |
| 03:43 | Ensure that the variable-length integer decoder in FTS3 never tries to left-shift a negative number. (check-in: 10ffc1fe00 user: drh tags: trunk) | |
| 01:06 | Fix a failure in sqlite3ExprCompare() (check-in: 835e2cc55f user: drh tags: trunk) | |

| 21:14 | Alternative implementation for the internal sqlite3Pow10() utility for MSVC, which is more accurate on that platform. (check-in: 469b96be53 user: drh tags: trunk) | |
| 20:57 | Fix a problem in the sessions module with logging sqlite_stat1 rows for which (idx IS NULL) is true. (check-in: 25bf734be1 user: dan tags: sessions-stat1) | |
| 17:38 | Fix a problem causing the sessions module to occasionally lose track of rows with composite primary keys when there are two rows with the same text value in the leftmost column of the PK. (check-in: 09aed13678 user: dan tags: trunk) | |
| 16:11 | Fix main.mk so that testfixture can be built either from the amalgamation or from individual source files. No changes to code. (check-in: a8aea925f8 user: dan tags: trunk) | |
| 13:15 | Fix harmless compiler warnings, mostly unused parameters for UDFs in the CLI. (check-in: bfbeffab77 user: drh tags: trunk) | |
| 12:58 | Omit the single test from zipfile.test that uses json functionality in non-SQLITE_ENABLE_JSON1 builds. (check-in: 6bb2a10fad user: dan tags: trunk) | |
| 12:57 | Update test file fts5fault6.test to account for test tokenizers implemented in Tcl returning SQLITE_ERROR instead of SQLITE_NOMEM following an OOM error. (check-in: c232f6424a user: dan tags: trunk) | |
| 01:40 | Simplifications to winOpenSharedMemory in the Win32 VFS. (check-in: 3e04999dab user: mistachkin tags: trunk) | |
| 01:26 | Corrections to error code handling in os_win.c, pursuant to walfault.test. (check-in: 568192228c user: mistachkin tags: trunk) | |
| 01:15 | Fix duplicate test names in 'walfault.test'. (check-in: 7274d05ff4 user: mistachkin tags: trunk) | |

| 10:41 | Fix a problem that could cause a spurious SQLITE_NOMEM error when attempting to resume an RBU operation if the previous client failed right after completing the incremental checkpoint. Also a "cannot vacuum wal db" error that could occur when resuming an RBU vacuum if an error (OOM or IO error) occurs during the incremental checkpoint. (check-in: 681d96eb82 user: dan tags: trunk) | |
| 00:10 | Disable intrinsic functions for Windows using Clang, due to reports of linkage errors. This causes a 0.6% performance reduction. We will want to revisit this change in the future. (check-in: 7fd560c6d2 user: drh tags: trunk) | |

| 21:32 | Here is a completely new implementation of the mutex-free-pcache. This one uses a common code base and automatically selects whether or not to use mutexes depending on compile-time and start-time options. (check-in: d094a1bfb7 user: drh tags: mutex-free-pcache) | |
| 18:36 | • Ticket [5d863f876e] DB corruption following rollback-WAL-VACUUM-rollback status still Open with 3 other changes (artifact: 97c044e265 user: drh) | |
| 18:30 | Fix a typo in the documentation for sqlite3_stmt_readonly(). (check-in: 56417a3386 user: drh tags: trunk) | |
| 17:42 | Add the SQLITE_OMIT_AUTORESET compile-time option which if enabled causes the sqlite3_step() routine to return SQLITE_MISUSE if it is called after it has previously returned anything other than SQLITE_ROW, SQLITE_BUSY, or SQLITE_LOCKED. (check-in: 053ce76deb user: drh tags: trunk) | |
| 02:24 | Add back an ALWAYS() to regain full test coverage. (check-in: b93f6f3e67 user: drh tags: trunk) | |

| 16:10 | Arrange for ThreadData to be automatically deallocated even if SQLITE_MEMDEBUG is defined. Fix for #1623. (CVS 2965) (check-in: 9e2e40845d user: danielk1977 tags: trunk) | |
| 15:36 | Fix compilation errors when building SQLITE_DEBUG defined but without SQLITE_MEMDEBUG. (CVS 2964) (check-in: 62dd242778 user: danielk1977 tags: trunk) | |
| 13:21 | Various fixes that allow the malloc() failure tests to pass again. (CVS 2963) (check-in: 0505405fb9 user: danielk1977 tags: trunk) | |
| 09:35 | Test suite fixes for builds that define OMIT symbols. (CVS 2962) (check-in: 3a54a33dcb user: danielk1977 tags: trunk) | |
