23:41 | Fix invalid use of unprotected sqlite3_value objects in the sqldiff utility, when using the --changeset option. (check-in: a8d65214 user: drh tags: trunk) | |
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) | |

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.

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) | |

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) | |

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) | |

15:01 | Test case modifications to support SEE. (check-in: 02b6f8f2 user: drh tags: trunk) | |
2018-10-11

18:45 | Fix issues with the new textkey pragma from the previous check-in. (check-in: d1008b07 user: drh tags: apple-osx) | |
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) | |

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) | |
