| ||
16:53 | Fix harmless compiler warnings in the CLI. (check-in: 1916d2912a user: drh tags: trunk) | |
16:38 | Always reset the pager before changing the codec. (check-in: 0bf0fd242b user: drh tags: trunk) | |
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) | |
02:39 | In the unix VFS, fix the heap shm allocator (used for unix-excl) so that it works even on systems where the page size is larger than 32KB. (check-in: 7fbb083c5c 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: 696e82f7c8 user: drh tags: trunk) | |
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) | |
20:37 | Merge fixes from trunk. (check-in: 9c8255a199 user: drh 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) | |
19:58 | Additional field name changes and commit fixes associated with shared-memory locking in the unix VFS, to improve maintainability. No logic changes. (check-in: 9280774a4b 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) | |
