20:04
When a table is renamed using "ALTER TABLE RENAME TO", update any REFERENCES clauses that refer to the table, unless "PRAGMA legacy_alter_table" is true and "PRAGMA foreign_keys" is set to false (i.e. so that when "PRAGMA legacy_alter_table" is set behaviour is still compatible with versions 3.24 and earlier).

13:53
Merge recent trunk enhancements. (check-in: 62acf7a0 user: drh tags: apple-osx)
07:53

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)

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)

17:08
In the sessions module, avoid collecting rebase data if the user has not requested it. (check-in: de72a773 user: dan 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

2018-10-25
16:58

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)

18:41
Add the textkey and textrekey pragmas. (check-in: f03164d4 user: drh 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)

01:01
Fix the build for Macs. (check-in: 6a1d937d user: drh tags: apple-osx)
2018-10-09
22:58
Merge enhancements from trunk. (check-in: 1b60e7a9 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)
