Following month ↑|
2018-10-31
| ||
| 20:52 | Deploy the sqlite3Strlen30NN() function (argument guaranteed to be non-NULL) for a small performance improvement. (check-in: 4a6ad5190b user: drh tags: trunk) | |
| 19:01 | Add support for the SQLITE_PREPARE_NORMALIZED flag and the sqlite3_normalized_sql() when compiling with SQLITE_ENABLE_NORMALIZE. Also remove unnecessary whitespace from Makefiles. (check-in: 790ea39a65 user: drh tags: trunk) | |
| 18:24 | Tweaks to the test_intarray documentation and tests. (check-in: 7107f0dacf user: drh tags: trunk) | |
| 01:26 | Merge fixes from trunk, especially rebustness against corrupt database files. (check-in: 4b370c74ae user: drh tags: apple-osx) | |
| 01:12 | Merge fuzz test cases computed by dbfuzz2. (check-in: e0d30c1862 user: drh tags: trunk) | |
| 01:04 | Improved corrupt database detection in the relocatePage() routine of the b-tree module. (check-in: d57873337a user: drh tags: trunk) | |
|
2018-10-30
| ||
| 23:45 | Add new fuzzer cases generated by dbfuzz2. (Closed-Leaf check-in: 79fdad8b42 user: drh tags: dbfuzz2-cases) | |
| 19:14 | Update comments in sqlite3session.c to describe the format of "rebase blobs", as well as changesets and patchsets. (check-in: bf93f7b56b user: dan tags: trunk) | |
| 16:25 | Split the SQLITE_WriteSchema flag in two flags, WriteSchema and SQLITE_NoSchemaError. Set only WriteSchema on a VACUUM to avoid problems when trying to vacuum a corrupt database. With this change, the size of the flags field on sqlite3 must grow from 32 to 64 bytes. (check-in: 4f9878107a user: drh tags: trunk) | |
| 15:31 | Modify the CLI so that the --deserialize option is only available if it is compiled with SQLITE_ENABLE_DESERIALIZE. DESERIALIZE is now off by default for the main.mk makefile, but on for Makefile.in and Makefile.msc. (check-in: 90b2a684f7 user: drh tags: trunk) | |
| 15:20 | Improvements to the -fsanitize=fuzzer based database file fuzzer. (Cherrypick from the rubust-against-damaged-db branch.) (check-in: 3cc01a0eaf user: drh tags: trunk) | |
| 14:36 | In the CLI, when opening a file that begins with the normal SQLite prefix, open the file as a normal database even if it has a ZIP for AppendVFS record at the end. (check-in: 7989bbda70 user: drh tags: trunk) | |
| 13:19 | Enable sqlite3_deserialize() in the CLI. The --deserialize option associated with opening a new database cause the database file to be read into memory and accessed using the sqlite3_deserialize() API. This simplifies running tests on a database without risk of modifying the file on disk. (check-in: 5e0129ee9a user: drh tags: trunk) | |
| 00:06 | Improvements to the -fsanitize=fuzzer based database file fuzzer. (Closed-Leaf check-in: 585c94db09 user: drh tags: robust-against-damaged-db) | |
| 00:06 | In the VACUUM command, defer setting writable_schema until after it has been determined that the schema is not corrupt. (check-in: 3afec26014 user: drh tags: robust-against-damaged-db) | |
|
2018-10-29
| ||
| 21:01 | Fix a potential assertion fault that can occur while trying to DROP a table from a corrupted database file. (check-in: 147a9429a5 user: drh tags: trunk) | |
| 18:33 | Fix minor memory leak in the dbstat extension that can occur following an attempt to analyze a corrupt database file. (check-in: cb874fd873 user: drh tags: trunk) | |
| 17:53 | Add the sqlite3_normalized_sql() API. (Closed-Leaf check-in: 592b66e805 user: mistachkin tags: normalized_sql) | |
| 17:08 | In the sessions module, avoid collecting rebase data if the user has not requested it. (check-in: de72a773dd user: dan tags: trunk) | |

| 16:02 | Add an entry in Makefile.in to build dbfuzz2 using clang-6.0 with -fsanitize=fuzzer,undefined. (check-in: a4a083ed8c user: drh tags: trunk) | |
| 00:47 | Initial code for a fuzzing tool on database file that works with the -fsanitize=fuzzer option of clang. (check-in: 90d12094d3 user: drh tags: trunk) | |
|
2018-10-26
| ||
| 17:05 | Add the sqlite3session_config() interface. For configuring global parameters belonging to the sessions module. (check-in: 1e69f3ff05 user: dan tags: trunk) | |
| 15:36 | Prevent an == constraint specified using the table-valued-function argument syntax from being used to optimize any scan not related to the virtual table for which it was specified as an argument. (check-in: 4d46685f28 user: dan tags: trunk) | |
|
2018-10-25

| 14:15 | In the WHERE-constraint propagation optimization, if there are duplicate constraint, make sure only one of them propagates. Proposed fix for ticket [cf5ed20fc8621b165]. (check-in: 5d5b596f15 user: drh tags: trunk) | |
| 11:55 | Speed up xAccess() calls made on an RBU VFS when there are lots of open connections. Cherrypick of [310b4b65]. (check-in: fda8fdb0cb user: dan tags: branch-3.22) | |

|
2018-10-20
| ||
| 13:48 | Add the sqlite3changeset_start_v2() - a new version of _start() that accepts a flags parameter - and a streaming equivalent to the sessions module. Also add the SQLITE_CHANGESETSTART_INVERT flag, used with start_v2() to invert a changeset while iterating through it. (check-in: cbedcb9aae user: dan tags: trunk) | |
|
2018-10-18
| ||
| 15:17 | Take steps to avoid a potential integer overflow in sessionBufferGrow(). (check-in: f7affa2e70 user: dan tags: trunk) | |
| 14:59 | Add the SQLITE_CHANGESETAPPLY_INVERT flag to sessions. For inverting and applying a changeset in a single step. (check-in: d4b6406e7f user: dan tags: trunk) | |
|
2018-10-12
| ||
| 22:02 | Fix the SQLITE_ENABLE_APPLE_SPI compile-time option. (check-in: 6cb537bdce user: drh tags: apple-osx) | |

| 14:07 | Remove surplus code in geopoly.c that seems to have come from a bad merge. (check-in: c486a63c33 user: drh tags: apple-osx) | |
| 13:57 | Merge enhancements from trunk. (check-in: 9e10d88bcb user: drh tags: apple-osx) | |
| 13:51 | On the first connection to a WAL-mode database that was not cleanly shut down and contains a left-over -shm file, truncate the -shm file to 3 bytes instead of to 0 bytes. Avoiding a truncation to 0 means that system monitoring tools can better detect if a process illegitimately tries to truncate a -shm file. Such a rogue process might think it is being helpful by cleaning up old files, but there is a race condition that can cause damage to the database. (check-in: 90cf32cde0 user: drh tags: trunk) | |
| 10:37 | In the CLI, fix a file descriptor leak following OOM and a missing va_end() call. (check-in: ec36d15a9e user: drh tags: trunk) | |

| 01:01 | Fix the build for Macs. (check-in: 6a1d937d66 user: drh tags: apple-osx) | |
|
2018-10-09
| ||
| 22:58 | Merge enhancements from trunk. (check-in: 1b60e7a981 user: drh tags: apple-osx) | |
| 22:50 | Merge changes for the 3.25.0 release. (check-in: ddf6a54ef3 user: drh tags: apple-osx) | |
|
2018-10-08
| ||
| 23:29 | Add the ability to open a database connection in -reuseschema mode in the CLI. Adjust memory allocation accounting so that a shared schema is allocated across each database sharing it. (check-in: 3869b2106b user: drh tags: reuse-schema) | |
| 20:57 | Fix a problem with using virtual tables via reuse-schema connections. (check-in: e5897dafda user: dan tags: reuse-schema) | |

| 20:04 | Fix an issue with the new memstat.c extension. (check-in: ce6e80b130 user: drh tags: trunk) | |
| 18:58 | Merge latest trunk changes into this branch. (check-in: 2ac72114a1 user: dan tags: reuse-schema) | |
| 18:55 | Replace the new geopoly_reverse() function with geopoly_ccw(). The geopoly_ccw() function only reverses the vertex order if doing so is necessary to get the correct right-hand winding rule on the polygon. (check-in: 075066944b user: drh tags: trunk) | |
| 12:58 | Add the geopoly_reverse() function to the GeoPoly extension. (check-in: 690dd18a57 user: drh tags: trunk) | |
|
2018-10-06
| ||
| 14:38 | Fix the ".help -all" option in the command-line shell. (check-in: aac8f1dff0 user: drh tags: trunk) | |
| 14:33 | Ensure each ALTER TABLE statement makes just a single SQLITE_ALTER_TABLE call to the authorizer function. (Leaf check-in: dac285474a user: dan tags: alter-auth-callbacks) | |
| 13:46 | Add test cases and assert() statements to ensure that the authorizer is being called as expected from within ALTER TABLE. (check-in: ff10d2c7de user: dan tags: trunk) | |
|
2018-10-05
| ||
| 20:09 | When the left-hand side of a WHERE clause contraint is a UNIQUE column, and that term of the WHERE clause is not used for indexing, assume that the term reduces the number of output rows by half. This is one proposed fix for ticket [e8b674241947eb3ba4] (Leaf check-in: 5c243eec7b user: drh tags: unique-constraint-weights) | |
| 15:10 | Changes to geopoly to silience false-positive warnings coming out of clang. (check-in: 11d9015f31 user: drh tags: trunk) | |
|
2018-10-04
| ||
| 18:17 | The 0x8000 optimization flag associated with SQLITE_TESTCTRL_OPTIMIZATIONS causes a large penalty (200) to be added to all sorting costs, which encourages the query planner avoid using the sorter. This flag can be used in experiments to help come up with a more accurate estimate of the true cost of sorting. (Leaf check-in: 857a1b01df user: drh tags: query-planner-debug) | |
|
2018-10-03
| ||
| 18:05 | Add an ALWAYS on an unreachable branch in the ALTER TABLE logic. (check-in: ebcd452317 user: drh tags: trunk) | |
| 11:13 | Change a type in shell.c.in from "int" to "sqlite3_int64" in order to avoid a compiler warning and possible integer overflow. (check-in: bf0a6634cd user: dan tags: trunk) | |
|
2018-10-02
| ||
| 20:16 | Add an additional assert() verifying mutex invariants on the unixShmSystemLock() routine in the unix VFS. (check-in: cb1511065d user: drh tags: trunk) | |

| 19:36 | Fix comments and refactor some names associated with shared-memory locking in the Unix VFS. No logical changes. (check-in: 3e9f163527 user: drh tags: trunk) | |
|
2018-10-01
| ||
| 21:41 | Add the "PRAGMA table_xinfo" command that works like table_info but also shows hidden columns in virtual tables and adds the "hidden" boolean column. (check-in: defa0515b8 user: drh tags: trunk) | |
| 21:36 | Test case for PRAGMA table_xinfo. (Closed-Leaf check-in: 7694b9bc30 user: drh tags: pragma-table-vinfo) | |
| 21:26 | Change the name of the pragma to PRAGMA table_xinfo. Improve the mkpragmatab.tcl script to reuse column names where appropriate. (check-in: 2fdd068987 user: drh tags: pragma-table-vinfo) | |
| 18:28 | Add the extra "hidden" column to the end of the PRAGMA table_vinfo output. (check-in: cf1b76135f user: drh tags: pragma-table-vinfo) | |
| 17:33 | Speed up xAccess() calls made on an RBU VFS when there are lots of open connections. (check-in: 310b4b65b8 user: dan tags: trunk) | |
| 17:15 | Bring the PRAGMA table_vinfo statement up to date with trunk. (check-in: 6f606f9923 user: drh tags: pragma-table-vinfo) | |
| 14:05 | Fix a potential crash that can occur while reading an index from a corrupt database file. The corruption is a record-header-size that is larger than 0x7fffffff. Problem detected by OSSFuzz against GDAL and reported to us (with a suggested fix) by Even Rouault. The test case is in TH3. (check-in: 5d29165896 user: drh tags: branch-3.25) | |
| 13:54 | Fix a potential crash that can occur while reading an index from a corrupt database file. The corruption is a record-header-size that is larger than 0x7fffffff. Problem detected by OSSFuzz against GDAL and reported to us (with a suggested fix) by Even Rouault. The test case is in TH3. (check-in: 8ac2cdda68 user: drh tags: trunk) | |
| 11:00 | Ensure that the OP_VColumn opcode does set sqlite3_vtab_nochange() unless the OPFLAG_NOCHNG bit is set in P5. Fix for ticket [69d642332d25aa3b7315a6d385] (check-in: 31ac8dbae4 user: drh tags: branch-3.25) | |
