| ||
| 16:19 | In RBU, avoid passing VFS xShmLock calls through to the underlying VFS in cases where xShmMap calls may not be. This fixes a bad interaction with ZipVFS. (Leaf check-in: 0c3838d9 user: dan tags: reuse-schema-3.31) | |
|
2020-04-04
| ||
| 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: 43612157 user: drh tags: branch-3.31) | |
|
2020-04-03

| 20:14 | Restore an #if block inadvertently removed via check-in [9c77bfe41e]. (check-in: bf6bcfc1 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: b6467491 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: 52f800fa 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: 2b750b0f 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: 9c77bfe4 user: drh tags: branch-3.31) | |

|
2020-01-28
| ||
| 20:27 | Faster decoding of 32-bit variable-length integers in cases were we do not need to know the number of bytes in the encoding. (check-in: 59a31b16 user: drh tags: trunk) | |
| 20:09 | Small performance improvement to the key-comparision routine for strings. (check-in: 41454499 user: drh tags: trunk) | |
| 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: 8ac26a23 user: drh tags: trunk) | |
| 16:55 | Fix a 4 byte OOB read in test_multiplex.c. (check-in: 91214891 user: dan tags: trunk) | |

| 17:09 | Update the version number to 3.31.1. (check-in: 6fb9a8fb 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: 34ab7606 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: 14331989 user: drh tags: trunk) | |

| 21:01 | Begin adding instrumentation to record and report on the set of key-ranges a concurrent transaction reads from the database. (check-in: c39e3c14 user: dan tags: begin-concurrent-report) | |
| 16:31 | Update test file exclusive.test so that it works with the "journaltest" permutation. (check-in: 4daf94d8 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: 934ee8bd 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: 3a62f642 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: 9265cb7f user: drh tags: trunk) | |
| 01:45 | Improvements to the autoconf TEA Makefile for MSVC. (check-in: cffcf12f user: mistachkin tags: trunk) | |

| 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: 63d886f4 user: drh tags: trunk) | |
|
2020-01-19

| 22:20 | In the TCL interface, add the ability to change the SQLITE_DBCONFIG_TRUSTED_SCHEMA setting using the "db config" method. (check-in: 1accfa8c 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: 8c8ce526 user: drh tags: trunk) | |
| 19:58 | Fix a couple of test case issues on this branch. (check-in: 9830a44b user: dan tags: reuse-schema) | |
| 19:46 | Do not use memcpy() of zero bytes when initializing a pager. This avoids a warning. (check-in: cca43778 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: 3c63f68e user: drh tags: trunk) | |
| 19:02 | Fix harmless compiler warning seen with MSVC. (check-in: cd0437ba user: mistachkin tags: trunk) | |
| 18:59 | Have this branch call sqlite3LockAndPrepare() instead of sqlite3Prepare() when parsing SQL for new schema objects in order to ensure that schemas are released as soon as possible. (check-in: 7a4ec579 user: dan tags: reuse-schema) | |
| 14:50 | Add extra front margin to the fake empty filename returned by sqlite3PagerFilename() for an in-memory or TEMP database. (check-in: fee94567 user: drh tags: trunk) | |

|
2020-01-17
| ||
| 23:27 | Fix a typo in a comment. No code changes. (check-in: 4363f69c 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: 84f31490 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: 7584e4b6 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: 4d6cb288 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: a370871e user: dan tags: trunk) | |
|
2020-01-16

| 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: 1bc783da user: drh tags: trunk) | |
| 13:02 | Very small performance improvement by ensuring that the argument to sqlite3VdbeFreeCursor() is non-NULL. Hold for the next sprint. (Leaf check-in: f8801ffd user: drh tags: close-cursor-faster) | |

| 17:18 | Fix the assert_schema_state_ok() routine so that it correctly ignores ATTACH-ed database that failed to open due to an error. (check-in: 1194a42a user: drh tags: reuse-schema) | |
| 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: 03b003c9 user: drh tags: trunk) | |
| 14:26 | Merge all recent enhancements and fixes from trunk. (check-in: f7839178 user: drh tags: reuse-schema) | |

| 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: 3e3c60d8 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: 0e468aa6 user: drh tags: trunk) | |

| 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: fd7bcc53 user: drh tags: trunk) | |
| 20:27 | Minor changes for consistency between sqlite3_filename_wal() and sqlite3_filename_journal(). (Closed-Leaf check-in: 9a70ff43 user: drh tags: enhanced-uri) | |
| 16:08 | Redesign for better legacy compatibility. Add the sqlite3_uri_key() interface. (check-in: bcb43d11 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: 2ae77bd2 user: drh tags: enhanced-uri) | |
| 01:05 | Fix to the register validity tracking logic in debug builds. No impact on release builds. (check-in: 0a500da6 user: drh tags: trunk) | |
| 00:20 | Begin making changes to turn off trusted schema in command-line tools that open SQLite databases. There are a lot of these, and a lot of places to change, which makes me wonder if trusted schema should be off by default. (Leaf check-in: 3d23a275 user: drh tags: default-untrusted-schema) | |

| 20:48 | In the typeof() optimization in OP_Column, expand the size of the bogus buffer provided for data so that it is big enough to cover the increased number of bytes displayed during register tracing from check-in [54553bf16fabd72d]. This is the correct fix for ticket [bbd55a97e66ff50d], though the earlier one does not hurt and is useful to retain. (check-in: e1154c39 user: drh tags: trunk) | |
