| ||
| 21:55 | Add a generation counter to the Schema object and enhance OP_VerifySchema to also check the Schema generation. Fix for ticket [f7b4edece25c99]. (check-in: 36c04dd169 user: drh tags: trunk) | |
|
2011-03-17
| ||
| 16:45 | Update the implementation of ".testctrl" in the command-line shell to use a look-up table rather than a long sequence of if-elses. Shorten source code lines of shell.c to 80 characters or less. (check-in: 54bacb95dd user: drh tags: trunk) | |
| 01:58 | Comment enhancement to better explain the logic in the "x IS NULL" optimization. (check-in: 869f894798 user: drh tags: trunk) | |
| 01:34 | Enhances to the query planner such that "x IS NULL" constraints take the STAT2 statistics into account, just like "x=VALUE" constraints. (check-in: 2353176811 user: drh tags: trunk) | |
|
2011-03-16
| ||
| 18:54 | Additional interpretation of flags and constants in the VFS trace output. (check-in: 3e984195f1 user: drh tags: trunk) | |
| 17:05 | Add the -vfstrace option to the usage error message in the shell. (check-in: baca45c549 user: drh tags: trunk) | |
| 16:56 | Add the VFS-trace shim. (check-in: f49a9ef338 user: drh tags: trunk) | |
|
2011-03-15
| ||
| 19:08 | Make the "unix-excl" VFS work exactly like "unix" if the database file is read-only. (check-in: d984683499 user: drh tags: trunk) | |

| 02:55 | Fix cut-and-paste typo in debugging print statement in winMutexTry(). (check-in: def98fd23e user: shaneh tags: trunk) | |
|
2011-03-14
| ||
| 13:54 | Merge the unix-excl VFS into the trunk. This merge also adds the -vfs option to the command-line shell. (check-in: 3934b004e9 user: drh tags: trunk) | |
|
2011-03-12
| ||
| 18:10 | In the "unix-excl" VFS, use the heap for shared memory, since only a single process is able to read or write the database. (Closed-Leaf check-in: a05a6d4087 user: drh tags: unix-excl) | |
| 17:02 | Add the new optional "unix-excl" VFS. This VFS grabs an exclusive lock on the database preventing other processes from accessing it, but continues to allow other database connections from the same process. (check-in: 00051c3296 user: drh tags: unix-excl) | |
| 04:58 | More tests for SQLITE_OMIT_UNIQUE_ENFORCEMENT and minor change to implementation. (check-in: b86999436e user: shaneh tags: trunk) | |
|
2011-03-11
| ||
| 16:15 | Remove an unused field from the unix sqlite3_file object. (check-in: f957f23a8a user: drh tags: trunk) | |
|
2011-03-10
| ||
| 21:48 | Simplification of tests and more added for SQLITE_OMIT_UNIQUE_ENFORCEMENT tests. (check-in: 75a38411a8 user: shaneh tags: trunk) | |
| 21:13 | Skip unique constraint enforcement if compiled with SQLITE_OMIT_UNIQUE_ENFORCEMENT. (check-in: ba85bf8cb8 user: shaneh tags: trunk) | |
| 03:54 | Minor clean-up of previous mem5 allocator fix. (check-in: 3643842316 user: shaneh tags: trunk) | |
|
2011-03-09
| ||
| 21:36 | Fix issue with mem5 allocator when min request size is larger thatn 2^30. (check-in: d7dae06fb2 user: shaneh tags: trunk) | |
| 21:02 | Omit unnecessary OP_Next and OP_Prev operators when uniqueness constraints guarantee that the code will only make one pass through the loop. (check-in: f000c9b2b7 user: drh tags: trunk) | |
| 11:04 | Updates to the OS/2 implementation from Rich Walsh. (check-in: dc46156a22 user: drh tags: trunk) | |
|
2011-03-08
| ||
| 16:39 | Merge the syscall-override changes into trunk. (check-in: 36d79e6f54 user: drh tags: trunk) | |
| 14:05 | Unix errno integer can vary from one system to the next. So do not depend on specific errno values in test cases. (check-in: ddb747d33a user: drh tags: trunk) | |
| 13:06 | Fix two compiler warnings. No functional code changes. (check-in: c829868aa2 user: drh tags: trunk) | |
| 02:38 | Fix additional cases of possible signed integer overflow, especially with regard to negation. (check-in: 2d5800bd8c user: drh tags: trunk) | |
|
2011-03-06
| ||
| 21:54 | Another minor simplification brought to light by clang. (check-in: 3bfbf026dd user: drh tags: trunk) | |
| 21:28 | Remove dead code identified by the clang static analyzer. (check-in: 01a79d5a7a user: drh tags: trunk) | |
|
2011-03-05
| ||
| 21:41 | Simplifications to the overflow-free multiplier. Also remove some commented-out code that was left in that subroutine by mistake on the previous check-in. (check-in: 55fc25fdab user: drh tags: trunk) | |
| 20:59 | Fix all known instances of signed-integer overflow. Within SQL expressions, integer overflow now forces coercion to floating point. The shift operators work with any integer right-hand operand with negative values reversing the direction of the shift. (check-in: abf2139412 user: drh tags: trunk) | |
| 13:54 | Fix an instance of signed arithmetic overflow and an one bit-shift overflow. Mark six other signed arithmetic overflow locations that need fixing. (check-in: 04abab71ec user: drh tags: trunk) | |
|
2011-03-04
| ||
| 15:43 | Handle EINTR errors from open(). (Closed-Leaf check-in: a7d176b27c user: drh tags: syscall-override) | |
| 00:56 | Do a better job of choosing the join table order when the tables having very different numbers of rows. (check-in: 952f5e8c69 user: drh tags: trunk) | |
|
2011-03-02
| ||
| 22:07 | Fix quoting of the result in rtreeB.test. (check-in: c6532b35cc user: drh tags: trunk) | |
| 19:06 | Add additional VFS methods to retrieve system call pointers and to get a list of all changeable system calls. (check-in: 3855836349 user: drh tags: syscall-override) | |
| 18:01 | Add more system calls to the set that can be overridden in os_unix.c. Also merge in recent fixes from trunk. (check-in: 80fac2a6e0 user: drh tags: syscall-override) | |
| 17:54 | Fix bugs in [7b6e30e6a7] that only show up on Mac. (check-in: ec55e8c6bb user: drh tags: trunk) | |
| 15:44 | Make sure the rtreenode() testing and analysis routine in the RTREE extension can handle 64-bit rowids. This fix is in response to a message on the mailing list. (check-in: 24602557fc user: drh tags: trunk) | |
| 15:09 | Proof-of-concept prototype for the proposed xSetSystemCall extension method on the VFS. (check-in: 92b5a76abc user: drh tags: syscall-override) | |
| 02:08 | Log all error from close() in os_unix.c to sqlite3_log() but do not attempt to report errors back up to the application. Update the unix error logging to put the most important information earlier in the message. (check-in: 7b6e30e6a7 user: drh tags: trunk) | |
|
2011-02-25
| ||
| 03:25 | Comment out some code in os_unix.c that only runs on MacOSX with SQLITE_ENABLE_LOCKING_STYLE. (check-in: 4e50b0362a user: drh tags: trunk) | |
|
2011-02-24
| ||
| 21:10 | Fix a typo in a comment. No changes to code. (check-in: af4756184a user: drh tags: trunk) | |
|
2011-02-23
| ||
| 22:39 | Reserve a range of bits in the SQLITE_OPEN_xxxx bit vector for future expansion. (check-in: 9b9046546d user: drh tags: trunk) | |
| 14:00 | Fix a typo in the robust_flock() macro for systems without EINTR. (check-in: af9ba2a6d2 user: drh tags: trunk) | |
| 13:33 | Retry selected system calls on unix when they fail with EINTR. (check-in: b9d29ea385 user: drh tags: trunk) | |
|
2011-02-22
| ||
| 03:34 | When a stale schema-cookie is seen, expire only the one statement that encountered the bad cookie, not every statement on the database connection. Ticket [b72787b1a7cea1f] (check-in: 1bca0a7e19 user: drh tags: trunk) | |
|
2011-02-21
| ||
| 17:49 | Fix a problem with "EXPLAIN QUERY PLAN SELECT count(*) FROM tbl". (check-in: 9f9f328825 user: dan tags: trunk) | |
| 11:46 | Have os_unix.c call sqlite3_log() following errors in certain system calls. (check-in: 01076528a4 user: dan tags: trunk) | |
|
2011-02-19
| ||
| 23:18 | An SQLITE_PROTOCOL error counts as a locking error for verification purposes. (check-in: e87d499a4f user: drh tags: trunk) | |
| 17:02 | Change a testcase() added by the previous checkin into an assert(). (check-in: 6f3dad32aa user: drh tags: trunk) | |
| 16:51 | Add testcase macros to verify that all return values from walTryBeginRead() are tested. (check-in: 262b6fca0b user: drh tags: trunk) | |
| 15:22 | Changes to make WAL more robust against SQLITE_PROTOCOL errors. (check-in: fd578a32f8 user: drh tags: trunk) | |
