| 14:59 | Add tests and a fix for program "changesetfuzz". check-in: 09b90db5 user: dan tags: changesetfuzz | |
|
2018-11-07
| ||

| 16:46 | Performance improvement in subroutine that decides whether or not a table is read-only. check-in: 6e4968b0 user: drh tags: read-only-shadow | |
| 16:12 | Merge the onefile permutation fix from trunk. check-in: e543bff8 user: drh tags: read-only-shadow | |

| 14:39 | Fix a problem with the handling of SQLITE_FCNTL_PRAGMA in the test_onefile.c demo. check-in: 13e21b7d user: dan tags: trunk | |
| 13:41 | Merge the permutations fix from trunk. check-in: b753d849 user: drh tags: read-only-shadow | |
| 11:56 | Partially revert [3e1a2f661], as some test scripts require separate $presql and $dbconfig variables. check-in: cbf85284 user: dan tags: trunk | |
| 02:17 | Add the SQLITE_DEFAULT_DEFENSIVE compile-time option. Fix up test cases so that they work with DEFENSIVE enabled. check-in: 3212733c user: drh tags: read-only-shadow | |
|
2018-11-06
| ||
| 20:08 | Update the changesetfuzz program to fuzz changeset schemas as well as data. check-in: 141a93c8 user: dan tags: changesetfuzz | |
| 19:26 | Enable DEFENSIVE mode by default for tests. This requires lots of case of turning DEFENSIVE off in order to dodgy things to the database for testing purposes. No all of those cases are yet handled, so "make test" does not run to completion. check-in: a1d6c671 user: drh tags: read-only-shadow | |
| 15:57 | Turn on defensive mode for running test scripts. Does not yet work. check-in: 1c1d24ed user: drh tags: read-only-shadow | |
| 14:03 | Only allow shadow table to be written from within a recursive SQL call. Omit the SQLITE_PREPARE_SHADOW flag. Some tests are failing because the tests depend on being able to write to shadow tables. check-in: d890c658 user: drh tags: read-only-shadow | |
| 13:37 | Add enforcement of read-only on shadow tables. This does not currently work since some virtual tables are attempting to update shadow tables using sqlite3_exec(). check-in: f79b47c9 user: drh tags: read-only-shadow | |
|
2018-11-05
| ||
| 23:01 | Initial code to make shadow tables read-only to ordinary SQL. The now xShadowName method is added to the sqlite3_module object and is used to identify potential shadow tables. The SQLITE_PREPARE_SHADOW argument to sqlite3_prepare_v3() is defined. It is designed to permit writing to shadow tables, but is currently an unused placeholder. check-in: 31942b3d user: drh tags: read-only-shadow | |
| 20:37 | Version 3.25.3 check-in: 89e099fb user: drh tags: release, version-3.25.3, branch-3.25 | |

| 19:37 | Add the SQLITE_DBCONFIG_DEFENSIVE flag. check-in: 11d98414 user: drh tags: trunk | |
| 16:38 | Eponymous virtual tables appear to exist in all schemas. This is an alternative and improved fix to the eponymous virtual table in trigger problem that was previously addressed by checkin [1fa74930ab56171e]. check-in: b8d35c4a user: drh tags: trunk | |
| 13:53 | Merge recent trunk enhancements. check-in: 62acf7a0 user: drh tags: apple-osx | |

| 13:35 | Fix a assert() in the query planner that can arise when doing row-value operations on a PRIMARY KEY that contains duplicate columns. Ticket [1a84668dcfdebaf12415d]. check-in: 1309c84a user: drh tags: branch-3.25 | |
| 07:53 | Disable the IS NOT NULL optimization when the IS NOT NULL operator is part of the ON clause of a LEFT JOIN. Fix for ticket [65eb38f6e46de8c75e188a17ec]. check-in: af39661e user: drh tags: trunk | |

| 16:51 | Add extra defenses against strategically corrupt databases to fts3/4. check-in: d44318f5 user: dan tags: trunk | |
| 16:09 | Add the SQLITE_DBCONFIG_DEFENSIVE flag. check-in: af3f29d4 user: drh tags: dbconfig-defensive | |
| 13:11 | Fix a assert() in the query planner that can arise when doing row-value operations on a PRIMARY KEY that contains duplicate columns. Ticket [1a84668dcfdebaf12415d]. check-in: dcb8c735 user: drh tags: trunk | |
|
2018-11-02
| ||
| 17:38 | Enhance triggers so that they can use table-valued-functions that exist in schemas outside of the schema in which the trigger is defined. check-in: 1fa74930 user: drh tags: trunk | |
|
2018-10-31
| ||
| 20:52 | Deploy the sqlite3Strlen30NN() function (argument guaranteed to be non-NULL) for a small performance improvement. check-in: 4a6ad519 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: 790ea39a user: drh tags: trunk | |
| 18:24 | Tweaks to the test_intarray documentation and tests. check-in: 7107f0da user: drh tags: trunk | |
| 01:26 | Merge fixes from trunk, especially rebustness against corrupt database files. check-in: 4b370c74 user: drh tags: apple-osx | |
| 01:12 | Merge fuzz test cases computed by dbfuzz2. check-in: e0d30c18 user: drh tags: trunk | |
| 01:04 | Improved corrupt database detection in the relocatePage() routine of the b-tree module. check-in: d5787333 user: drh tags: trunk | |
|
2018-10-30
| ||
| 23:45 | Add new fuzzer cases generated by dbfuzz2. Closed-Leaf check-in: 79fdad8b 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: bf93f7b5 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: 4f987810 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: 90b2a684 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: 3cc01a0e 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: 7989bbda 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: 5e0129ee user: drh tags: trunk | |
| 00:06 | Improvements to the -fsanitize=fuzzer based database file fuzzer. Closed-Leaf check-in: 585c94db 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: 3afec260 user: drh tags: robust-against-damaged-db | |
|
2018-10-29
| ||

| 18:33 | Fix minor memory leak in the dbstat extension that can occur following an attempt to analyze a corrupt database file. check-in: cb874fd8 user: drh tags: trunk | |
| 17:53 | Add the sqlite3_normalized_sql() API. Closed-Leaf check-in: 592b66e8 user: mistachkin tags: normalized_sql | |
| 17:08 | In the sessions module, avoid collecting rebase data if the user has not requested it. check-in: de72a773 user: dan tags: trunk | |
| 16:07 | Harden the dbstat extension against corrupt database files. check-in: a0d47f25 user: drh tags: trunk | |
|
2018-10-27
| ||

| 16:02 | Add an entry in Makefile.in to build dbfuzz2 using clang-6.0 with -fsanitize=fuzzer,undefined. check-in: a4a083ed 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: 90d12094 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: 1e69f3ff 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: 4d46685f user: dan tags: trunk | |
|
2018-10-25
| ||
| 16:58 | Merge bug fixes from trunk. check-in: 1e973f65 user: drh tags: apple-osx | |
| 15:25 | 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: caebf879 user: drh tags: branch-3.25 | |
| 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: 5d5b596f 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: fda8fdb0 user: dan tags: branch-3.22 | |
|
2018-10-24

| 23:55 | Add the ENABLE_GEOPOLY case to the compile_options pragma. check-in: de940296 user: drh tags: trunk | |
|
2018-10-23
| ||
| 13:48 | Fix a problem with using window functions in compound (UNION, INTERSECT etc.) queries. check-in: 059ff53a user: dan tags: trunk | |
|
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: cbedcb9a user: dan tags: trunk | |
|
2018-10-18
| ||
| 15:17 | Take steps to avoid a potential integer overflow in sessionBufferGrow(). check-in: f7affa2e 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: d4b6406e user: dan tags: trunk | |

| 13:57 | Merge enhancements from trunk. check-in: 9e10d88b 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: 90cf32cd user: drh tags: trunk | |
| 10:37 | In the CLI, fix a file descriptor leak following OOM and a missing va_end() call. check-in: ec36d15a user: drh tags: trunk | |

|
2018-10-10
| ||
| 18:56 | In the CLI, allow the SQLITE_HISTORY environment variable, if it exists, to specify an alternative file in which to store the shell edit history. check-in: 696e82f7 user: drh tags: trunk | |
| 01:01 | Fix the build for Macs. check-in: 6a1d937d 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: 3869b210 user: drh tags: reuse-schema | |
| 20:57 | Fix a problem with using virtual tables via reuse-schema connections. check-in: e5897daf user: dan tags: reuse-schema | |

| 20:04 | Fix an issue with the new memstat.c extension. check-in: ce6e80b1 user: drh tags: trunk | |
| 18:58 | Merge latest trunk changes into this branch. check-in: 2ac72114 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: 07506694 user: drh tags: trunk | |
| 12:58 | Add the geopoly_reverse() function to the GeoPoly extension. check-in: 690dd18a user: drh tags: trunk | |

| ||
| 14:38 | Fix the ".help -all" option in the command-line shell. check-in: aac8f1df 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: dac28547 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: ff10d2c7 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: 5c243eec user: drh tags: unique-constraint-weights | |
| 15:10 | Changes to geopoly to silience false-positive warnings coming out of clang. check-in: 11d9015f 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: 857a1b01 user: drh tags: query-planner-debug | |
|
2018-10-03
