100 check-ins occurring around ed759d5a9e.

2011-02-19
15:22
Changes to make WAL more robust against SQLITE_PROTOCOL errors. check-in: fd578a32 user: drh tags: trunk
14:19
Changes which attempt to address an obscure SQLITE_PROTOCOL error. Leaf check-in: 1725aa75 user: drh tags: wal-trace-375
2011-02-18
17:23
Fix the sqlite3ValueFromExpr() routine so that it returns SQLITE_NOMEM on an OOM when trying to extract a NULL. check-in: 1061e94f user: drh tags: trunk
2011-02-17
15:58
Remove a no-op code path from sqlite3ExprIsInteger(). Replace it with an assert() that proves it always does nothing. check-in: 7af66d1b user: drh tags: trunk
13:52
Remove an assert() that was made redundant by the previous checkin. check-in: 21db7191 user: drh tags: trunk
13:33
Add an ALWAYS() around a always-true test in where.c. check-in: 8123283e user: drh tags: trunk
2011-02-16
23:32
Fix harmless compiler warnings in the query planner. check-in: 31fc4ba6 user: drh tags: trunk
01:23
Add "do_not_use_codec" logic to some of the TCL based test cases that read/write directly to the DB. check-in: edd27669 user: shaneh tags: trunk
2011-02-14
03:49
Skip some tests in capi3e.test when compiled with SQLITE_OMIT_UTF16. check-in: b04304b9 user: shaneh tags: trunk
2011-02-12
14:23
Fix the expected output on tests so that it corresponds to the new query planner results. All of veryquick.test is now passing with SQLITE_ENABLE_STAT2. check-in: f2a8b5cc user: drh tags: branch-3.7.2
05:34
Fix problems in the backport, reducing the number of errors in the TCL tests to just a few dozen. Most of the remaining errors seem to be real and desirable changes of behavior. check-in: 9d2b0af2 user: drh tags: branch-3.7.2
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
20:52
Skip flattening if subquery has LIMIT and outer query is DISTINCT. Fix for ticket [752e1646fc]. check-in: 55973999 user: shaneh 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
21:08
Add .testctrl option to CLI. check-in: f85afa0e user: shaneh tags: trunk
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
19:55
Make sure code *compiles* with each OMIT and ENABLE option. Mostly changes to test modules. check-in: 7cc515ed user: shaneh tags: trunk
18:19
Do not report corruption if the the db size header field is greater than the file size on disk unless the two change-counter header fields are identical. Fix for ticket [89b8c9ac54]. check-in: 00c4596f user: dan tags: trunk
15:25
Update Makefile.in for fts3_aux changes. check-in: 38b7cb33 user: shaneh tags: trunk
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

15:12
Change blocking-checkpoint tests so that they run once using "PRAGMA wal_checkpoint" and once using calls to sqlite3_wal_checkpoint_v2(). Also fix edge cases surrounding the output variables set by wal_checkpoint_v2(). check-in: 5a4b6652 user: dan tags: trunk
2011-02-05
15:47
Ensure fts4aux can handle a table name in single or double quotes as a constructor argument. check-in: 929d62e4 user: dan tags: trunk
14:37
Add test cases for fts4aux. Fix a bug affecting fts3 tables with multiple columns. check-in: dc511e60 user: dan tags: trunk
2011-02-04
18:56
Change fts4aux to (additionally) report on term frequency in individual columns of an fts table. check-in: 3996f92a user: dan tags: trunk
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

Optimize handling of equality and range constraints on the "term" column of an fts4aux table. check-in: 386701de user: dan tags: trunk
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
04:40
Merge fts4aux branch. check-in: c6d9f7d8 user: dan tags: trunk

18:00
Fix a problem causing builds with SQLITE_OMIT_WAL defined to fail. check-in: b9b48dd8 user: dan tags: fts4aux
17:55
Fix a case in fts4 where a corrupt %_stat table could lead to a crash. check-in: 4ade96ce user: dan tags: fts4aux
16:34
Add virtual table module "fts4aux", used to inspect the full-text index of an fts4 table directly. Also add the "compress" and "uncompress" fts4 options. check-in: b010ddcc user: dan tags: fts4aux
00:04
Version 3.7.5 check-in: ed759d5a user: drh tags: trunk, release, version-3.7.5

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
15:07
When extending a database file, do so by writing one or more page-size chunks of data to the file, instead of just a single byte to the end. check-in: 58577135 user: dan 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
15:23
Update test file mutex1.test to account for [e3b500fb5d]. check-in: c86e46f4 user: dan tags: trunk
13:28
More mutexes around another sqlite3StatusAdd() call. check-in: e3b500fb user: drh tags: trunk

07:25
Update mutex1.test so that it works with the memsubsys1 permutation (pagecache memory). Change a few instances of SQLITE_MUTEX_STATIC_LRU2 in comments and test code to STATIC_PMEM. check-in: 456bd5c6 user: dan tags: trunk
06:13
Changes to exclusive2.test to make it more deterministic. check-in: 84b0c2bc user: dan 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
13:43
Fix a couple of typos in comments. No changes to actual code. check-in: 9167fdb3 user: dan 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
16:00
Ensure that if a deferred FK constraint is violated by a statement that creates its own implicit transaction, the statement is not an "active-write" after sqlite3_step() returns. Closed-Leaf check-in: 8063197e user: dan tags: deferred-fk-quirk
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
13:32
Modify the trace callback mechanism so that SQL commands executed from within virtual table or user function callbacks are passed to the trace callback without parameter expansion and enclosed in SQL comments. check-in: a764915b user: dan tags: trunk
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
18:25
Change sqlite3StrAccumAppend() to use realloc instead of malloc. check-in: 380f61df user: dan tags: trunk
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
15:52
Add options to test command [do_faultsim_test] to support testing VFS implementations. check-in: 503ad889 user: dan tags: trunk
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

21:58
Comment improvements in pcache1.c. No changes to code. check-in: 9660a0a2 user: drh tags: trunk
2011-01-18
17:34

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
