| 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) | |

| 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) | |

|
2018-10-20
| ||
| 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

| 16:28 | Fix a merge problem in main.mk (check-in: 9a54935917 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) | |

|
2018-10-10
| ||

| 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

| 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) | |

|
2018-09-29
| ||
| 19:38 | Add the PRAGMA table_vinfo command (with an extra "v" before "info") that works like PRAGMA table_info (without the "v") except that it also shows hidden columns on virtual tables. (check-in: 8bcd1a5956 user: drh tags: pragma-table-vinfo) | |
|
2018-09-28
