2011-02-12
| ||
| 01:59 | This is the beginning of an attempt to backport recent query planner enhancements to version 3.7.2. The code in this version builds and runs and seems to give correct answers, but it generates suboptimal query plans and hence many of the test cases fail. The test script gives up after 1000 errors. (check-in: e72cf118 user: drh tags: branch-3.7.2) | |
|
2011-02-11
| ||
| 22:54 | Add a NEVER() around a test that is believed to always be false. (check-in: f7e2ea33 user: drh tags: trunk) | |
| 06:59 | Fix a bug in the new WHERE-clause processing that tries to use an index to resolve IS NOT NULL constraints when SQLITE_ENABLE_STAT2 is defined. The bug could cause memory overruns and segfaults. The bug was new to the code and has not appeared in an official release. Found during structural testing. (check-in: a5c36b9f user: drh tags: trunk) | |
| 03:56 | Allow an index paired with an IS NULL constraint to be used for sorting under the condition that the index be treated as a non-unique index. (check-in: d78949fc user: drh tags: trunk) | |
| 02:43 | Disable unused NULL tests when SQLITE_ENABLE_STAT2 is not in use. (check-in: 5ecd1178 user: drh tags: trunk) | |
|
2011-02-10
| ||
| 18:56 | Split the documentation for sqlite3_wal_checkpoint_v2() and its constants onto separate pages. No changes to code. (check-in: 0ef8ffd1 user: drh tags: trunk) | |
| 17:46 | Prevent a segfault when automatic indices try to use a column with an unknown collating function. Ticket [77aa3b1e6592582e38605d36]. This check-in also removes some stray \r characters unrelated to the problem. (check-in: f01030a0 user: drh tags: trunk) | |
| 01:49 | This is a version of the SQLite 3.7.5 release with Apple's changes for MacOS. (check-in: 55d2e55b user: drh tags: apple-osx) | |
| 00:08 | Refactor the cost function in the query planner. Give extra cost (thus reduce likelihood of selection) to full table scans. (check-in: 878da276 user: drh tags: trunk) | |
|
2011-02-09
| ||
| 03:04 | Use macros to define the relative costs of search and seek operations when computing costs in the query planner. Current constants seems wrong and need to be fixed, but doing so will alter test results. Need more experimentation to determine accurate relative costs. (check-in: 5f2ec44b user: drh tags: trunk) | |
| 03:03 | Simplifications to the sqlite3_wal_checkpoint_v2() logic. (check-in: 652b8835 user: drh tags: trunk) | |
|
2011-02-07
| ||
| 23:56 | Cleanup to the OP_Checkpoint opcode. (check-in: f611a5a8 user: drh tags: trunk) | |
|
2011-02-04
| ||
| 14:28 | Significant changes have occurred since the 3.7.5 release so go ahead and increase the version number to 3.7.6. (check-in: 999c915a user: drh tags: trunk) | |
| 06:36 | Merge the stat2 query planner enhancements into the trunk. (check-in: 499edcbc user: drh tags: trunk) | |
| 05:47 | If a deferred foreign key constraint fails on a statement that is not part of a larger transation, make sure that the statement fully ends so that subsequent invocations of the same statement will not pass the constraint because they think the transaction is not closed. This is a merge of the deferred-fk-quirk branch together with a test case. (check-in: 2f94d462 user: drh tags: trunk) | |
| 00:51 | Fix the ATTACH command so that the filename argument can be any expression and so that if authorizer callback gets a NULL pointer for the filename if the filename argument is anything other than a string literal. Ticket [9013e13dba5b58c7] (check-in: e64e1453 user: drh tags: trunk) | |
|
2011-02-03
| ||
| 01:26 | Fix a superlock test case to conform to the new wal_checkpoint returns. (check-in: 8bf2d51b user: drh tags: trunk) | |
|
2011-02-02
| ||
| 16:34 | Merge in the blocking-checkpoint enhancement, including the new sqlite3_wal_checkpoint_v2() interface and the PRAGMA wal_checkpoint(full) statement. (check-in: bac7342c user: drh tags: trunk) | |
|
2011-02-01
| ||
| 00:04 | Version 3.7.5 (check-in: ed759d5a user: drh tags: trunk, release, version-3.7.5) | |
|
2011-01-28
| ||
| 17:02 | Bogus release candidate. (Closed-Leaf check-in: 38ca1daa user: drh tags: mistake) | |
| 15:46 | Change pager_truncate() to a different method for extending files while also ensuring that writes are page-size and page-aligned. (check-in: 874bc884 user: drh tags: trunk) | |
| 03:13 | Reactivate the analyze5.test script. (Closed-Leaf check-in: a2a9f640 user: drh tags: stat2-enhancement) | |
| 01:57 | Change the weighting of binary searches on tables to 1/10th the cost of a search on an index. Change the assumed reduction in search space from a indexed range constraint from 1/3rd to 1/4th. Do not let the estimated number of rows drop below 1. (check-in: 4847c6cb user: drh tags: stat2-enhancement) | |
|
2011-01-27
| ||
| 18:48 | Pull in all the changes from trunk up through the version 3.7.5 release candidate 1. (check-in: 09d6c91d user: drh tags: apple-osx) | |
| 14:35 | SQLite version 3.7.5 release candidate 1 (check-in: 35ac78f5 user: drh tags: trunk) | |
|
2011-01-26
| ||
| 19:46 | Update all built-in VFSes to return SQLITE_OK for the SQLITE_FCNTL_SYNC_OMITTED file-control operation. Also change the xFileControl methods to return SQLITE_NOTFOUND for unrecognized operation codes. (check-in: 6f2c72a0 user: drh tags: trunk) | |
| 13:28 | More mutexes around another sqlite3StatusAdd() call. (check-in: e3b500fb user: drh tags: trunk) | |
| 13:24 | Add a mutex around an sqlite3StatusAdd() call to prevent the pagecount overflow measurements from getting off in multithreaded applications. (check-in: 3d8b298d user: drh tags: trunk) | |
| 00:07 | Rename the PCache1.mxPinned field to n90pct (since it is 90% of nMax) in order to distinguish it from PGroup.mxPinned. Fix the computation of n90pct so that it does not overflow adversely on excessively large cache sizes. (check-in: c85202ba user: drh tags: trunk) | |
|
2011-01-25
| ||
| 18:30 | Fix new compiler warnings in pcache1.c that were introduced by the recent performance enhancement patches of [e14649301138b684]. (check-in: c17703ec user: drh tags: trunk) | |
| 16:48 | Make sure the return code from doing an xSync is correctly initialized so that a valid return code is produced regardless of the path taken through the logic. (check-in: f12b5d76 user: drh tags: trunk) | |
| 16:20 | Change the name of SQLITE_FCNTL_SYNC to SQLITE_FCNTL_SYNC_OMITTED and only send it when PRAGMA synchronous=OFF. Add better documentation to explain what that file-control opcode is used for. (check-in: 64914980 user: drh tags: trunk) | |
| 04:34 | Shave a few cycles so that performance is better than 3.7.4 in speed tests. (check-in: e1464930 user: drh tags: trunk) | |
|
2011-01-24
| ||
| 20:18 | Modify the test_quote.c demonstration shim so that it works when SQLITE_THREADSAFE=0 is defined. (check-in: b70bccca user: drh tags: trunk) | |
| 19:45 | Fix a typo in the documentation for sqlite3_snprintf(). No changes to code. (check-in: 8d106541 user: drh tags: trunk) | |
| 19:14 | Fix a harmless compiler warning (a shadowed local variable) in analyze.c. (check-in: a1ad7fb3 user: drh tags: trunk) | |
| 17:46 | Restructuring and generalizing analyze5.test. The whole script is currently disabled and will need to be reenabled prior to merging with trunk. (check-in: 31fcc706 user: drh tags: stat2-enhancement) | |
| 15:11 | Change the cost estimator in the query planner to take into account the logN rowid lookup cost when going from an index to a table. (check-in: b442525b user: drh tags: stat2-enhancement) | |
|
2011-01-22
| ||
| 00:10 | Add the ability to use indices for constraints of the form "x IS NOT NULL" when sqlite_stat2 is available and most entries for column x are NULL. (check-in: 5d5bddd2 user: drh tags: stat2-enhancement) | |
|
2011-01-21
| ||
| 18:18 | Adjustments to the result row estimator for the IN operator so that it gives the same estimates as the equivalent OR operator. Test cases for the same. (check-in: c82cb9c0 user: drh tags: stat2-enhancement) | |
| 16:27 | Make use of histogram data to make better estimates for the number of rows that will be returned from "x IN (v1,v2,v3,...)" constraints. (check-in: fd3977a2 user: drh tags: stat2-enhancement) | |
| 14:37 | Add the ability to use indices when a range contraint is bounded on the lower end by NULL. (check-in: f73a167b user: drh tags: stat2-enhancement) | |
|
2011-01-20
| ||
| 20:36 | Update ANALYZE test cases to check out the use of histograms for equality constraints. (check-in: c7b59afa user: drh tags: stat2-enhancement) | |
| 16:52 | Use histogram data to improve the row-count estimates on equality constraints. (check-in: 6bfc5c69 user: drh tags: stat2-enhancement) | |
| 02:56 | The first of a planned series of enhancements to the query planner that enable it to make better use of sqlite_stat2 histograms when the table has many repeated values. (check-in: 2cd374cd user: drh tags: stat2-enhancement) | |
|
2011-01-19
| ||
| 21:58 | Comment improvements in pcache1.c. No changes to code. (check-in: 9660a0a2 user: drh tags: trunk) | |
|
2011-01-18
| ||
| 17:34 | Pull over all the latest trunk changes. (check-in: ca86d04b user: drh tags: wal-trace-375) | |
| 17:03 | Do not use mutexes in the pcache implementation unless SQLITE_ENABLE_MEMORY_MANAGMENT is defined. This is a performance enhancement. A side effect is that pcaches will not steal pages from one another unless ENABLE_MEMORY_MANAGEMENT is set, or unless SQLITE_THREADSAFE=0. (check-in: e5ca59e6 user: drh tags: trunk) | |
| 16:13 | Get all test cases working with the mutex-free-pcache implementation. (Closed-Leaf check-in: 2dc98d29 user: drh tags: mutex-free-pcache) | |
| 15:17 | Do not use SQLITE_MUTEX_STATIC_MEM2 since it has been reused as STATIC_OPEN. Instead, create a new static mutex STATIC_PMEM which is an alias for the unused STATIC_LRU2. (check-in: f1cf02ef user: drh tags: mutex-free-pcache) | |
|
2011-01-17
| ||
| 21:32 | Here is a completely new implementation of the mutex-free-pcache. This one uses a common code base and automatically selects whether or not to use mutexes depending on compile-time and start-time options. (check-in: d094a1bf user: drh tags: mutex-free-pcache) | |
| 18:30 | Fix a typo in the documentation for sqlite3_stmt_readonly(). (check-in: 56417a33 user: drh tags: trunk) | |
| 17:42 | Add the SQLITE_OMIT_AUTORESET compile-time option which if enabled causes the sqlite3_step() routine to return SQLITE_MISUSE if it is called after it has previously returned anything other than SQLITE_ROW, SQLITE_BUSY, or SQLITE_LOCKED. (check-in: 053ce76d user: drh tags: trunk) | |
| 02:24 | Add back an ALWAYS() to regain full test coverage. (check-in: b93f6f3e user: drh tags: trunk) | |
|
2011-01-16
| ||
| 22:37 | On a backup from a smaller to a larger page size, do not begin committing the transaction until the source pages after the pending byte have been copied. (check-in: 612e2599 user: drh tags: trunk) | |
| 00:56 | Make sure the change-counter and SQLite-version fields of the header are set correctly even when doing a VACUUM with locking_mode=EXCLUSIVE. Ticket [5d863f876ee9561b]. (check-in: 04fa1e16 user: drh tags: trunk) | |
|
2011-01-15
| ||
| 21:42 | Make sure the change counter and SQLite version numbers in the header are set correctly, even when running in WAL mode and when VACUUMing in WAL mode. Ticket [5d863f876ee9561b9]. (check-in: 0be92a75 user: drh tags: trunk) | |
| 18:11 | Fix the change-counter increment for WAL pages so that it works even when invoked from xStress. Ticket [5d863f876ee9561b95e2]. (Closed-Leaf check-in: 228e7c34 user: drh tags: bug-5d863f87) | |
| 17:12 | Increment the change counter and update the SQLite version number whenever page 1 is added to the WAL. Ticket [5d863f876ee9561b9] (check-in: c1e0d09c user: drh tags: bug-5d863f87) | |
|
2011-01-14
| ||
| 16:43 | Rerun autoconf to bring the configure script up-to-date. (check-in: 14217464 user: drh tags: trunk) | |
| 16:12 | Provide an alternative and experimental pcache implementation that avoids the use of mutexes at the expense of using more memory. (Closed-Leaf check-in: 2ea5bd12 user: drh tags: mutex-free-pcache) | |
| 15:17 | Fix comments, including some documentation comments, in the page cache logic. No code changes. (check-in: c80e9c1a user: drh tags: trunk) | |
|
2011-01-13
| ||
| 16:10 | Fix a typo on the sqlite3_open_v2() documentation. (check-in: b0add45a user: drh tags: trunk) | |
|
2011-01-12
| ||
| 17:56 | Do not raise an SQLITE_CORRUPT error in Recoverymode if the database size in the header is larger than the physical file size. This facilitates recovery of a database in which the database size field has been corrupted. (check-in: 114640d9 user: drh tags: trunk) | |
|
2011-01-11
| ||
| 17:38 | Change the page size of the destination database in a backup, if it is changeable, prior to starting the backup. (check-in: a5e4e0ca user: drh tags: trunk) | |
| 12:46 | Fix the sqlite3.h generator script so that it generates the correct SQLITE_SOURCE_ID string with the latest versions of Fossil that include fractional seconds on the date/time stamp. (check-in: 3513bf6e user: drh tags: trunk) | |
| 01:42 | A proposed change to the sqlite3_step() API such that it will only auto-reset following an SQLITE_BUSY or SQLITE_LOCKED error. Calls after any other result other than SQLITE_ROW will return SQLITE_MISUSE. (Closed-Leaf check-in: d1b3c54f user: drh tags: step-autoreset) | |
|
2011-01-10
| ||
| 21:01 | Update pager requirements to account for the ZIPVFS extension. (check-in: d94e59b5 user: drh tags: trunk) | |
|
2011-01-07
| ||
| 02:50 | Reorder the fields in private structures in an effort to reduce alignment gaps and thus make the structures smaller, and to put frequently accessed fields first. Also update some obsolete comments. Valgrind shows a very slight performance improvement. (check-in: 378a1d13 user: drh tags: trunk) | |
|
2011-01-06
| ||
| 15:51 | Enhance the showdb tool to show overflow page pointers at the end of overflow cells. (check-in: cda5eab1 user: drh tags: trunk) | |
| 01:26 | Enhance the showdb tool to show a btree page layout. Add limit checks so that overflow content does not overflow the buffer. (check-in: 57ffa07e user: drh tags: trunk) | |
|
2011-01-05
| ||
| 21:46 | Fix a bug in the showdb utility: the serial types for BLOB and TEXT where reversed. (check-in: 65a13faf user: drh tags: trunk) | |
| 21:20 | Enhancements to the "showdb" debugging tool. Add the ability to display the content of a cell. (check-in: e9023a4e user: drh tags: trunk) | |
| 13:43 | Increment the version number to 3.7.5. (check-in: 9ec3896e user: drh tags: trunk) | |
| 13:07 | Cherrypick the WAL error logging from the pre-3.7.5 line into a branch for version 3.7.2. Include the sqlite3_vsnprintf() interface. This checkin is intended for debugging and not for release. (Leaf check-in: 6549e767 user: drh tags: wal-trace-372) | |
| 12:50 | Add detailed error logging to WAL in an effort to track down an obscure SQLITE_PROTOCOL problem. This code is intended for debugging and not for release. (check-in: 2c2afdd0 user: drh tags: wal-trace-375) | |
| 12:20 | Add the sqlite3_vsnprintf() interface. (check-in: fc67adea user: drh tags: trunk) | |
|
2011-01-04
| ||
| 20:06 | Fix a null-pointer dereference that can occur on an OOM error while running ANALYZE with SQLITE_ENABLE_STAT2. (check-in: 73128d4e user: drh tags: trunk) | |
| 19:01 | Fix the ANALYZE command so that it takes collating sequences into account when gathering index statistics. (check-in: a5867cfc user: drh tags: trunk) | |
| 17:57 | The ANALYZE command now counts at all rows of an index, even those containing NULL values. A valid sqlite_stat1 entry is created even if the index contains nothing but NULLs. (check-in: 824c8dd3 user: drh tags: trunk) | |
|
2010-12-22
| ||
| 21:48 | Do not include <sys/mmap.h> if SQLITE_OMIT_WAL is defined. (check-in: b82e85ec user: drh tags: trunk) | |
|
2010-12-21
| ||
| 21:28 | Add test cases for the new lookaside hit and miss status outputs. Add the output of lookaside hit and miss to the command-line shell statistics. (check-in: b0888047 user: drh tags: trunk) | |
| 20:36 | Merge into the trunk the experimental enhancements to sqlite3_db_status() for measuring lookaside memory allocator performance. (check-in: 8c3b06c2 user: drh tags: trunk) | |
| 00:20 | Remove the obsolete compile-time option SQLITE_THREAD_OVERRIDE_LOCK from the autoconf makefile. Needed only for LinuxThreads, which we no longer support. (check-in: 09f6c053 user: drh tags: trunk) | |
| 00:16 | Rearrange a variable declaration in the proxy locking code to avoid a harmless compiler warning on recent MacOS versions. (check-in: 39bbd355 user: drh tags: trunk) | |
|
2010-12-20
| ||
| 17:00 | Clarify the documentation of the SQLITE_STATUS_MALLOC_COUNT parameter to sqlite3_status(). (check-in: 3b41bcc3 user: drh tags: trunk) | |
| 15:51 | Add additional DBSTATUS options for measuring the hit and miss rates against the lookaside memory pool - information useful in tuning the lookaside size. Currently experimental pending analysis of performance impact. (Closed-Leaf check-in: 34613f1d user: drh tags: experimental) | |
|
2010-12-17
| ||
| 14:03 | Add the "-heap" option to the command-line shell - to allocate a fixed heap for use with SQLITE_ENABLE_MEMSYS5. (check-in: 74fff692 user: drh tags: trunk) | |
| 01:00 | Fix minor typos in the sqlite3_backup documentation. (check-in: df430be5 user: drh tags: trunk) | |
|
2010-12-16
| ||
| 20:35 | Improvements to the documentation for sqlite3_backup. No code changes. (check-in: f83609f4 user: drh tags: trunk) | |
| 19:52 | Fix an assertion fault that can only occur if SQLITE_ENABLE_STAT2 is defined and the constant folding optimization is disabled using sqlite3_test_control(). Problem introduced by [ad8bc68197f2b4] but we missed it prior to the 3.7.4 release due to taking shortcuts and skipping tests in the release checklist. (check-in: 70a3d817 user: drh tags: trunk) | |
| 02:06 | Make wal_checkpoint a no-op if a prior checkpoint has already copied all WAL content into the database. This prevents a concurrent write to the database from resetting the wal-index out from under the WalIterator of the checkpoint as it is initializing. (check-in: cf86affc user: drh tags: trunk) | |
|
2010-12-15
| ||
| 21:02 | Enhanced comments in wal.c and declare some procedure parameters "const". No changes to the generated code. (check-in: d0e4375b user: drh tags: trunk) | |
| 18:54 | When registering the built-in LIKE and GLOB functions, make sure that they are tagged with SQLITE_UTF8 so that if other application-defined LIKE and GLOB implementations are provided for UTF16, then the appropriate function will be selected. (check-in: e1660764 user: drh tags: trunk) | |
|
2010-12-09
| ||
| 19:15 | Add support for the SQLITE_DEFAULT_FOREIGN_KEYS compile-time option. (check-in: c959945a user: drh tags: trunk) | |
| 18:55 | Mention the SQLITE_DEFAULT_WAL_AUTOCHECKPOINT compile-time option in the documentation for the sqlite3_wal_autocheckpoint() interface. (check-in: 5a52dd59 user: drh tags: trunk) | |
|
2010-12-08
| ||
| 18:30 | Update the sqlite3_stmt_readonly() interface so that its output is well-defined for all prepared statements, and so that it gives the correct result for VACUUM. (check-in: 9c19b7ae user: drh tags: trunk) | |
| 03:28 | The command-line shell ignore errors in sqlite3_close() when shutting down. (check-in: 925332c3 user: drh tags: trunk) | |
| 00:02 | Changes to the shell which should, in theory, allow it to work with libeditline as an alternative to libreadline. (check-in: e474fd9e user: drh tags: trunk) | |
|
2010-12-07
| ||
| 23:24 | Improved documentation for SQLITE_FCNTL_FILE_POINTER. (check-in: 43935548 user: drh tags: trunk) | |
| 20:14 | Version 3.7.4 (check-in: a586a4de user: drh tags: trunk, release, version-3.7.4) | |
| 15:49 | Merge in all changes to the trunk through version 3.7.4rc3. (check-in: d2ccf7fc user: drh tags: apple-osx) | |
| 14:59 | Version 3.7.4 release candidate 3 (check-in: 11c74c0d user: drh tags: trunk) | |
|
2010-12-06
| ||
| 21:09 | Fix the build so that it once again works with SQLITE_OMIT_SHARED_CACHE and SQLITE_OMIT_AUTOVACUUM. (check-in: fabcb6b9 user: drh tags: trunk) | |
| 21:06 | Add the ability to disable constant factoring using sqlite3_test_control(). Add a TCL interface to this new capability and add tests cases to the TCL test scripts to actually use the new capability. (check-in: ad8bc681 user: drh tags: trunk) | |
| 18:59 | Back out part of the previous change that was not really necessary in order to fix [80ba201079ea60], and which in fact serves no useful purpose. (check-in: fa9eef86 user: drh tags: trunk) | |
| 18:50 | Initialize all constants at the very beginning of a prepared statement. Do not allow constant initialization to occur once control flow has a chance to diverge, to avoid the possibility of having uninitialized registers. Ticket [80ba201079ea60807]. (check-in: c5c53152 user: drh tags: trunk) | |
|
2010-12-04
| ||
| 19:35 | Version 3.7.4 release candidate 2. (check-in: 40756fe1 user: drh tags: trunk) | |
|
2010-12-03
| ||
| 18:57 | Remove an over-zealous call to memAboutToChange() from OP_MustBeInt. OP_MustBeInt will never invalidate the Mem.z pointer so the memAboutToChange() call is not necessary. (check-in: 841cf7a7 user: drh tags: trunk) | |
| 15:41 | Version 3.7.4 release candidate 1 (check-in: 2e800cb8 user: drh tags: trunk) | |
|
2010-11-26
| ||
| 16:49 | Fix various compiler warnings. (check-in: c412f612 user: drh tags: trunk) | |
|
2010-11-24
| ||
| 13:04 | Fix a couple of compiler warnings in test_superlock.c. Add superlock.c to the Makefile.in used by the configure script. (check-in: 461f1a01 user: drh tags: trunk) | |
|
2010-11-23
| ||
