22:05
Fix a performance regression: Keep two btree masks in each prepared statement; one for btrees used and another for btrees that require locks. Only try to lock the btrees identified by the second mask. (check-in: 614de91a user: drh tags: trunk)
19:15

Merge the latest trunk changes into the apple-osx branch. (check-in: c77a767c user: drh tags: apple-osx)
22:08
Suppress many harmless compiler warnings, mostly signed/unsigned comparisons within asserts or unused parameters in extensions. (check-in: 3eeb0ff7 user: drh tags: trunk)
19:27
Simplifications to the sqlite3BtreeEnterAll() and LeaveAll() routines. Just have them call BtreeEnter and BtreeLeave() repeatedly rather than trying to be clever. (check-in: 51039b35 user: drh tags: trunk)
19:26
Simplifications to the sqlite3ResetInternalSchema() logic to eliminate unreachable branches. (check-in: a4c3ac98 user: drh tags: trunk)
18:34
Remove dead code from the OP_JournalMode opcode in the VDBE. This code seems to have been useless since [f88c6367d2] on 2010-08-07. (check-in: a89f24e2 user: drh tags: trunk)
17:31
Remove the mutex counter and the logic that attempts to verify that btree mutexes are held continuously. We are not making that assumption at this time. (check-in: 242ce7cf user: drh tags: trunk)
16:09
When committing a WAL transaction, do not write any pages to the WAL file with page numbers greater than the size of the database image in pages. (check-in: 311d0b61 user: dan tags: trunk)

13:12
Merge the scheme-parse-refactor changes into trunk: (1) added sqlite3SchemaMutexHeld() asserts, (2) Use -1 instead of 0 to mean "all" in sqlite3ResetInternalSchema(), and other cosmetic changes. (check-in: 5db4511d user: drh tags: trunk)
12:25
Fix the P4_TRANSIENT constant so that it works correct - so that it really makes a copy of the string for the P4 argument. Use P4_TRANSIENT wherever appropriate. Change P4_STATICs of schema names to P4_TRANSIENT. (check-in: bf664b20 user: drh tags: trunk)
11:26
Improved comment on the sqlite3SrcListLookup function. (check-in: bcbc9ff5 user: drh tags: trunk)

2011-04-04
23:08
Add a comment to the VACUUM implementation explaining when all schemas are reset and not just the "main" schema. (Closed-Leaf check-in: 2aff1b0c user: drh tags: schema-parse-refactor)
21:48
Changes for consistent use of SQLITE_OS_UNIX and removal of legacy OS_UNIX from testfixture source; (check-in: 78b6eee2 user: shaneh tags: trunk)
21:25
Additional schema mutex checks for sqlite3RootPageMoved(). Reduce the scope of sqlite3ResetInternalSchema() in a few places. (check-in: 39c00907 user: drh tags: schema-parse-refactor)
20:40
Minor comment typo corrections. Simplify an assert. No functional changes. (check-in: 82c23162 user: drh tags: schema-parse-refactor)
18:22
Add a description of access rules for the Schema object and lots of asserts to verify that the access rules are followed. (check-in: ae8374af user: drh tags: schema-parse-refactor)
15:38
Add the "--start=[permutation:][testfile]" option to tester.tcl. For starting quick.test or all.test at the nominated permutation and/or test file. (check-in: a97e8505 user: dan tags: trunk)
14:05
Merge test_syscall.c fix from the trunk. (check-in: 1e1a23cc user: dan tags: schema-parse-refactor)
14:03
Have test_syscall.c include "sqliteInt.h". Otherwise the SQLITE_OS_UNIX symbol may not be defined correctly. (check-in: fda8fadd user: dan tags: trunk)
13:40
Rename sqlite3SchemaFree() to sqlite3SchemaClear() to more accurately reflect its function. (check-in: 71d74400 user: drh tags: schema-parse-refactor)

Merge in the latest changes from trunk. (check-in: 47b79c40 user: drh tags: schema-parse-refactor)
12:29
Move the expired-statement test for OP_Function until after all memory has been freed. The test is still commented out, however. (check-in: 425e3edb user: drh tags: trunk)
07:05
Changes to oserror.test and syscall.test so that they work with the in-memory journal permutation test. (check-in: 4e996f36 user: dan tags: trunk)
03:27
Suppress unused parameter warnings in sqlite3VdbeEnter() and related routines. (check-in: f8e98ab3 user: drh tags: trunk)
00:14
Remove the BtreeMutexArray object - use the Vdbe.btreeMask field to accomplish the same result. Add a generation counter to btree mutexes in order to assert that mutexes are never temporarily dropped over a range of instructions in order to do deadlock avoidance in some subroutine. Lock all btrees in any Vdbe program that uses OP_ParseSchema. (check-in: d81708f7 user: drh tags: trunk)
2011-04-03
18:19
Make sure that the constant 1 is cast to yDbType before shifting to create an attached database mask. This check-in is a follow-up and fix to the [7aaf8772274422] change that increases the maximum number of attached databases from 30 to 62. (check-in: e2a09ea7 user: drh tags: trunk)

20:01
Change the name of the "tAttachMask" datatype to "yDbMask". (check-in: 3d6f2e82 user: drh tags: trunk)
17:00
Avoid returning SQLITE_NOTFOUND when the unix xSetSystemCall interface is invoked with NULL passed as the second argument, even if all the default system calls are already installed. (check-in: 3b91eaaa user: dan tags: trunk)
16:50
When resetting any non-TEMP schema, also reset the TEMP schema since it might be holding references to the non-TEMP schema that just got reset. (check-in: 211d5dde user: drh tags: schema-parse-refactor)
16:28
Begin a series of changes designed to reduce the scope and frequency of invalidating schemas. Design goals are that the internal schema should never be deleted out from under a prepared statement that is running and that all prepared statements should be expired if the schema is invalidated. At the same time, minimize the number of schema invalidations. This change merely revises the sqlite3ResetInternalSchema() function to use -1 as the wildcard for "all" rather than 0, so that we can reset the main schema independently of all the others. (check-in: 6a8ad6e3 user: drh tags: schema-parse-refactor)
09:44
Fix a race condition in OP_ParseSchema. (check-in: 71a799b0 user: dan tags: trunk)
09:25

06:44
Fix additional test cases so that they work with DEFAULT_AUTOVACUUM. (check-in: 139bc565 user: dan tags: trunk)
2011-04-01
23:49
Add the "wholenumber" virtual table module to the test suite - useful in populating tables with many rows of content prior to a test. (check-in: 975dff15 user: drh tags: trunk)
20:54
Fix up the Makefile.in so that the configuration script works for "make test". (check-in: 2e03830c user: drh tags: trunk)
20:47
Merge the word-fuzzer branch into trunk. (check-in: f77609d4 user: drh tags: trunk)
20:28
Add additional test data and documentation to the fuzzer virtual table. (Closed-Leaf check-in: a6a81d4f user: drh tags: word-fuzzer)
19:14
Changes to wal tests so that they work with DEFAULT_AUTOVACUUM defined. (check-in: b477852f user: dan tags: trunk)
18:39
Merge the multiplexer enhancements back into the trunk. (check-in: 2c125710 user: drh tags: trunk)
18:12
Add a script that will break the amalgamation source file up into 4 or 5 smaller source files, each 32K lines or fewer, and a single "sqlite3-all.c" source file that #includes the others. (check-in: 5d34e64d user: drh tags: trunk)
17:53
Change analyze7.test so that it works without SQLITE_ENABLE_STAT2 defined. (check-in: 9415201c user: dan tags: trunk)
16:50
When simulating an error in the close() system call, close the file descriptor anyway. Otherwise long running tests leak too many file-descriptors and crash. (check-in: 81ddbf43 user: dan tags: trunk)
15:43
Merge latest trunk changes. (check-in: d184cf00 user: dan tags: sessions)
15:30

15:15
Ensure that it is not possible to add a column to a system table using ALTER TABLE. (check-in: d9707ef8 user: dan tags: trunk)
14:26
Merge the ANALYZE-index enhancement into trunk. (check-in: 7e237aea user: drh tags: trunk)
14:22
Removed dependency on sqliteInt.h so that multiplex VFS shim can be compiled as loadable module. (Closed-Leaf check-in: 718f1ad7 user: shaneh tags: multiplex-enhancements)
14:04
Test cases for ANALYZE-index. (Closed-Leaf check-in: 365896cb user: drh tags: analyze-idx)

11:56
In os_unix.c, do not return SQLITE_BUSY to SQLite following an error in fcntl(F_UNLCK), regardless of the value of errno. (check-in: ff6dfe6e user: dan tags: trunk)
09:04
Fix some problems in os_unix.c when compiled with ENABLE_LOCKING_STYLE on OSX. Also some minor issues with test scripts. (check-in: 8088031b user: dan tags: trunk)

2011-03-31
18:36
Provide hints to the btree layer Next and Previous primitives to let them know if they can be no-ops if the underlying index is unique. (check-in: a5aae174 user: drh tags: branch-3.7.2)
15:11
Enable/disable support. (check-in: b3c6d9aa user: shaneh tags: multiplex-enhancements)
13:14
Add tests and fixes for SELECT multiplex_control(op, val); (check-in: fee9734c user: shaneh tags: multiplex-enhancements)

Additional test cases; Round chunk size up to a multiple of max page size; (check-in: 36e364a3 user: shaneh tags: multiplex-enhancements)
02:03
Change the ANALYZE command so that it will accept an index name as its argument and only reanalyze that one index. A quick smoke-test works. Need to study the implications to the query planner and test corner cases. (check-in: c8f9edd9 user: drh tags: analyze-idx)
2011-03-30
21:04
Add the SQLITE_ENABLE_PREUPDATE_HOOK compile-time option. (check-in: 66345214 user: drh tags: sessions)

02:03
Merge in all the latest changes from trunk. (check-in: b11d941e user: drh tags: sessions)
01:43
Move to an O(NlogN) algorithm for the priority queue. An insertion sort was way too slow. (check-in: 7958cbba user: drh tags: word-fuzzer)
2011-03-29
23:41
Add support for rowid. (check-in: 2cf4158f user: drh tags: word-fuzzer)
18:28
Add tests to syscall.test and sysfault.test. (check-in: 3d2de011 user: dan tags: trunk)
18:21
The first simple test-case appears to be working now. (check-in: dd41155b user: drh tags: word-fuzzer)
15:40
Fix a problem whereby following an IO error in CommitPhaseTwo() of a multi-file transaction the b-tree layer could be left in TRANS_WRITE state, causing problems later on. (check-in: dbe569a0 user: dan tags: trunk)
15:00
If the keyword "unordered" appears at the end of the SQLITE_STAT1.STAT column for an index, then use that index for equality lookups only, never for range queries or sorting. (Closed-Leaf check-in: 3b964155 user: drh tags: unordered-index-hack)
14:08
Further improvements to the fuzzer. It still is not quite working. Pausing to work on other things.... (check-in: 5f2f2fce user: drh tags: word-fuzzer)
10:04
Fix a problem in the unix VFS implementation of xNextSystemCall(). Also some typos that prevent compilation when HAVE_POSIX_FALLOCATE is defined. (check-in: bc6cce81 user: dan tags: trunk)
05:06
In-progress changes - do not use; Removed prefix support; Added file control interface to enable/disable and adjust chunk size; added app-def function for same; (check-in: bc02d0c1 user: shaneh tags: multiplex-enhancements)
01:47
Fix the documentation for the sqlite3_column_*_name() functions to describe that the information can be invalidated when a prepared statement is reprepared by the first invocation of an sqlite3_step() for a particular execution cycle. (check-in: 7270f80a user: drh tags: trunk)
2011-03-28
19:10

2011-03-26
19:04
Added most of the logic. Simple test runs without segfaulting but does not give the correct answer. (check-in: fb4c31ea user: drh tags: word-fuzzer)
15:05
Skeleton code for the word-fuzzer virtual table. (check-in: ea3a4ee1 user: drh tags: word-fuzzer)
