2013-05-20
13:01
Update the sessions branch to the official 3.7.17 release code. (check-in: fc88f731 user: drh tags: sessions)
00:56
Version 3.7.17 (check-in: 118a3b35 user: drh tags: trunk, release, version-3.7.17)
2013-05-17
20:16
Remove a stray tab character from the transitive_closure extension source code. (check-in: 7a9aa21c user: drh tags: trunk)
17:15
Fix a bug in SQLITE_TRACE_SIZE_LIMIT that was introduced by check-in [1a1cf5aa86734c8]. That check-in was to remove harmless compiler warnings. So once again, we have introduced a real bug into SQLite by attempting to eliminate a harmless compiler warning. (check-in: cec2bcb4 user: drh tags: trunk)
16:41
In test file test_syscall.c, include sqliteInt.h before any tcl or system include files. This ensures that the magical defines in sqliteInt.h really do enable large file support (and set things up so that sizeof(off_t)==8). (check-in: 0f355bb1 user: dan tags: trunk)
12:52
Use sum() instead of total() in mptest/multiwrite01.test too. (check-in: d0c2288c user: drh tags: trunk)
12:51
Use sum() instead of total() in the mptest/crash01.test script. (check-in: 8ba0fc98 user: drh tags: trunk)
12:25
Add extra "PRAGMA mmap_size = N" statements to mmap1.test and mmap2.test. (check-in: cec0a06c user: dan tags: trunk)
12:10
In os_unix.c and os_win.c, initialize the default mmap-limit of a new file descriptor to the current global default mmap-limit, not the current global maximum allowable mmap-limit. (check-in: 1def4ea3 user: dan tags: trunk)
10:58

Fix compilation with SQLITE_OMIT_WAL on Win32. (check-in: 6d45a79f user: mistachkin tags: trunk)
11:57
In sqlite3_close_v2(), do not attempt to roll back a transaction if there exist active statement objects. Any open transaction will be rolled back when the last of these statement objects is finalized. (check-in: d11e7607 user: dan tags: trunk)
01:02
Treat identifiers in the HAVING clause the same as in the WHERE clause. Only consider AS names from the result set to match if there are no other matches. Continuation of the fix for [2500cdb9be05]. This check-in fixes a bug found by SqlLogicTest during release testing for version 3.7.17. (check-in: 9ffff3d0 user: drh tags: trunk)

Fixes to allow testfixture to be compiled with SQLITE_OMIT_VIRTUAL_TABLE defined. (check-in: 00231fb0 user: dan tags: trunk)
17:47
The sqlite3ExprCollSeq() function can no longer be called while parse the schema, so remove the code path inside of sqlite3ExprCollSeq() that dealt with that case. (check-in: 867b3e3b user: drh tags: trunk)
17:08
Make sure an sqlite3_close() or a rollback on one shared-cache connection does not disrupt the operation of other connections using the same shared cache. Fix for ticket [e636a050b709]. (check-in: 5cc1cc55 user: drh tags: trunk)
16:24
Extra test for commit [6dae62c4e5]. (check-in: b10b9e75 user: dan tags: trunk)

15:16
When loading a database schema that contains an index definition that includes a COLLATE clause for which the collation sequence is unavailable, do not assume that that index uses BINARY instead. Fix for [0fc59f908b]. (check-in: 6dae62c4 user: dan tags: trunk)
13:05
Add the rot13.c loadable extension. (check-in: 8f9bd8e7 user: drh tags: trunk)
10:21
When closing a connection, avoid tripping active cursors belonging to a different shared-cache client. Also, if sqlite3_close() is called while there are still active statements belonging to the connection, return SQLITE_BUSY and do not roll back any active transaction. Proposed fix for ticket [e636a050b709]. (check-in: 6071b7cc user: dan tags: shared-cache-fixes)
