2011-10-21
17:18
Merge the latest trunk changes into the apple-osx branch. (check-in: be62ef05 user: drh tags: apple-osx)
17:08
Merge the latest trunk enhancements into the sessions branch. (check-in: 8baef581 user: drh tags: sessions)
16:47
Remove stale requirements marks from the query planner. (check-in: 76de9914 user: drh tags: trunk)
14:27
If an error occurs while writing to the database file during a VACUUM, discard the contents of the in-memory cache. This is required as if the database is a zipvfs database, the contents of the cache may be inconsistent with respect to the database as stored on disk. (check-in: 07159e84 user: dan tags: trunk)
2011-10-20
18:23
Fix an issue with finding the access permissions of journal files when 8+3 filenames are in use. (check-in: 2b35c514 user: drh tags: trunk)
00:55
Enhancements to the omittest.tcl script used to verify that the SQLITE_OMIT compile-time options are working. (check-in: 4344483f user: drh tags: trunk)
2011-10-19
18:21
Fix harmless compiler warnings in FTS4. (check-in: 1af4a256 user: drh tags: trunk)

Fix comments on SQLITE_CONFIG_HEAP so that they do not interfere with the requirements scanner. (check-in: a3151ce1 user: drh tags: trunk)
16:20
Merge the fts4-content branch with the trunk. (check-in: 8a407705 user: dan tags: trunk)
2011-10-18
22:07
Fix the virtual table rename logic so that it works even if the database encoding is something other than UTF8. Ticket [8290242b2a9a81683] (check-in: d65f6353 user: drh tags: trunk)
19:14
Fix an uninitialized variable in OR-clause processing. (check-in: 54aecd92 user: drh tags: trunk)
18:10
Improved handling of USING and NATURAL JOIN in 3-way and higher joins. Ticket [3338b3fa19ac4ab] (check-in: 551ce407 user: drh tags: trunk)
12:44
Fix a floating-point exception that can occur when an FTS4 query contains a large number of tokens connected by AND or NEAR operators. (check-in: 3126754c user: dan tags: trunk)
2011-10-17
23:15
Change the OP_JournalMode implementation so that it works even if a substitute sqlite3PagerFilename() that might return NULL is used. (check-in: 491ff5fb user: drh tags: trunk)
20:41
Avoid 32-bit integer overflow when evaluating the exponent of a floating point value during ascii to binary conversion. (check-in: 4becc47e user: drh tags: trunk)
12:14
Performance improvement for ascii to floating-point conversions with very large exponents. (check-in: 59bb999c user: drh tags: trunk)
2011-10-15
00:16
Added the tool/warnings-clang.sh script. Changes so that there are no warnings with either gcc or clang even including FTS4 and RTREE and both with and without SQLITE_THREADSAFE=0. (check-in: 39408702 user: drh tags: trunk)
2011-10-14
22:57
Fix a few minor and harmless clang warnings in FTS3 and RTREE. (check-in: b3324f6c user: drh tags: trunk)
21:49
Add assert() statements and eliminate needless variable assignments in order to get the clang scan-build utility to report zero problems against the SQLite core. Clang's static analysis did find one real problem - but it was in the command-line shell, not in the SQLite core. (check-in: 60fee957 user: drh tags: trunk)
2011-10-13
18:08

18:00
Simplifications to the upper() and lower() SQL functions. Updates to documentation on sqlite3_bind_text() and sqlite3_result_text() to make it clear that users should not try to create strings with embedded NULs and that if they do the result of expression on those strings is undefined. Ticket [57c971fc74524a] (check-in: 9984cc20 user: drh tags: trunk)
17:16
Handle updating the only row of an FTS table correctly. Fix for [9fd058691]. (check-in: 7e24645b user: dan tags: trunk)
17:09
An improved fix for the page_count and quick_check problem previously patched at [150592b4b4d8637] (check-in: c3cb7f4f user: drh tags: trunk)
16:36
Provide a complete prototype for isatty() in the command-line shell sources. (check-in: 8bf13b03 user: drh tags: trunk)
16:30
Change the command-line shell to do the ".dump" inside of a SAVEPOINT rather than a transaction, since this allows it to be run from within a transaction. (check-in: 6df7343b user: drh tags: trunk)
16:02
Enable large-file support for fopen() and friends in the command-line shell. Ticket [92af7da36b6fbd] (check-in: eeeba4f0 user: drh tags: trunk)
15:35
Make sure the query optimizer for aggregate queries knows that expressions (x='a') and (x='A') are different. Ticket [fa7bf5ec94801e7e] (check-in: e43da426 user: drh tags: trunk)
14:41
Make sure the page_count and quick_check pragmas work properly even when their names are capitalized. Fixes a problem reported on the mailing list. (check-in: 150592b4 user: drh tags: trunk)
14:18
Adjust the symbols.sh script for STAT3. Add the symbols-mingw.sh script for testing on windows with MinGW. (check-in: c41d1d46 user: drh tags: trunk)
14:05
Make sure all non-API functions in os_win.c have file scope. Ticket [35c54c874987] (check-in: 17e4fde5 user: drh tags: trunk)
13:34
Do the ".dump" command inside of a transaction to prevent other processes from modifying the database while the dump is underway. Ticket [2466653295e65] (check-in: 1c00d545 user: drh tags: trunk)
01:01
Fix a harmless compiler warning introduced into os_unix.c by one of the recent changes. (check-in: 4bf4d5eb user: drh tags: trunk)
00:41
If errors are encountered while processing the ".dump" command in the command-line shell, print error messages as comments in the output and ROLLBACK at the end rather than committing. Ticket [ee19e690ec9a5a2] (check-in: 8a8dcd6b user: drh tags: trunk)
00:11
Be sure to allocate plenty of space for error messages coming out of sqlite3_load_extension(), so that filenames and procedure names are not truncated. Ticket [7d32c69b50f89d] (check-in: af8bcdd9 user: drh tags: trunk)
2011-10-12
23:49
The sqlite3_overload_function() interface returns an error if it is unable to create the overload function. Ticket [20f9d4fbbff3a3] (check-in: d5b6b374 user: drh tags: trunk)
23:13
The date/time functions return NULL if the xCurrentTime or xCurrentTimeInt64 VFS methods fail. Ticket [0b803bff856c644c] (check-in: c96651dd user: drh tags: trunk)
19:04
Suppress a compiler warning that occurs with SQLITE_OMIT_VIRTUALTABLE. (check-in: 6bedb49d user: drh tags: trunk)

Clean up obsolete comments in printf.c. (check-in: 97ef4f50 user: drh tags: trunk)
17:00
Clarify a comment and fix a code formatting issue in btree.c. (check-in: 4f1a558d user: drh tags: trunk)
2011-10-11
20:41
Put in code to defend against signed/unsigned character problems in the command-line shell. (check-in: b94a80a8 user: drh tags: trunk)
20:14
Add a couple of asserts trying to make the operation of sqlite3SelectNew() clearer. (check-in: b21b1c7b user: drh tags: trunk)
18:38
Simplify the readonly_shm implementation so that it conforms to the implementation on trunk. Update the test cases to agree with the new behavior. (check-in: 9efb74ce user: drh tags: apple-osx)
18:18
Change the behavior of the readonly_shm=1 query parameter so that it never attempts to open the -shm file read/write. (check-in: f1364004 user: drh tags: trunk)
17:54
Remove all precision and width limits from formatting fields in the sqlite3_mprintf() family of functions. Malloc for space as necessary. The prevents a stack overflow on very large numbers using %f. (check-in: 1f843fb3 user: drh tags: trunk)

Fix a locking error introduced when porting the new Apple locking code. (check-in: cce1f521 user: drh tags: apple-osx)

2011-10-10
16:06
Enhance sqlite3_analyzer so that it is able to deal with multiplexed databases that have 8+3 filenames. (check-in: e5169f9a user: drh tags: trunk)
12:04
Fix a typo in a comment for PRAGMA journal_mode. Also amplify that same comment. (check-in: c8ff2a48 user: drh tags: trunk)

All the soft_heap_limit to be exceeded by 10% in test cases. (check-in: 4be9dccc user: drh tags: trunk)
