15:41
Check that a unique index uses the default collation sequences for each column before using it as part of a foreign key constraint operation. (check-in: 64154174 user: dan tags: trunk)
11:28
Remove an unused variable from fkey.c. (check-in: 582bd768 user: dan tags: trunk)
06:33
Various fixes so that "make test" works with OMIT_FOREIGN_KEY, OMIT_TRIGGER and OMIT_ALTER_TABLE. (check-in: e4eb227b user: dan tags: trunk)
2009-09-28
18:52
Ignore foreign key mismatch errors while compiling DROP TABLE commands. (check-in: 5b4d4637 user: dan tags: trunk)
14:49
Fix the DROP TABLE command so that it cannot be used to bypass foreign key constraints (if foreign key support is enabled). (check-in: 8353808c user: dan tags: trunk)
11:54
Fix some foreign key constraint related problems that occur when a row refers to itself. (check-in: 9e503e2d user: dan tags: trunk)
2009-09-26
17:51
When ALTER TABLE RENAME TO is used to change the name of a table that is the parent table of a foreign key constraint, modify that foreign key constraint to use the new table name. (check-in: b4a10c39 user: dan tags: trunk)
2009-09-25
17:03
Avoid checking if an insert or delete has "fixed" an outstanding FK constraint violation if the constraint counter indicates that the database contains no such violations. (check-in: 519144ac user: dan tags: trunk)
12:00
Fix comments in fkey2.c to reflect the immediate-constraint-counter approach. (check-in: 9fd54b0a user: dan tags: trunk)
11:26
Prevent ALTER TABLE from being used to add a column with a REFERENCES clause and a non-NULL default value while foreign key support is enabled. (check-in: 353b1b18 user: dan tags: trunk)
2009-09-24
18:19
Fixes and test cases to make sure the affinity and collation sequence associated with the parent key is used when comparing it with a child key value. (check-in: 76e8e74b user: dan tags: trunk)
16:52
Fix a bug in the code for REPLACE conflict handling on IPK columns when there are no indexes on the table. Triggers and foreign key processing were being bypassed. (check-in: beb2094f user: dan tags: trunk)
15:16
Fix a problem in fkey.c when a child key is the IPK of its table. (check-in: 8a000a8a user: dan tags: trunk)
14:27
Remove the ALWAYS() added by the previous check-in. It is not needed. (check-in: 36568963 user: drh tags: trunk)
13:48
Comment enhancements. Add an ALWAYS macro in fkey.c to indicate a branch that is always taken. (check-in: d5b714cf user: drh tags: trunk)
11:31
Ensure foreign key related processing takes place when rows are deleted from the database by REPLACE conflict handling. (check-in: 3f40c142 user: dan tags: trunk)
10:42
Use sqlite3FkOldmask() in delete.c instead of assuming that foreign key constraints always require all columns of the deleted row to be stored in registers. (check-in: ce554a39 user: dan tags: trunk)
09:05
Remove unused parameter from sqlite3CodeRowTrigger(). Fix header comments for this function and CodeRowTriggerDirect(). (check-in: 0443f7c9 user: dan tags: trunk)
00:09

18:49
More fkey tests. (check-in: 2d544bd5 user: shane tags: trunk)

17:31
Fix a problem in the fkey_malloc.test script. (check-in: 0ce1efa4 user: dan tags: trunk)
17:30
Do not check immediate foreign key constraints until the end of the statement. This matches the postgres behaviour. (check-in: 1a32149c user: dan tags: trunk)
15:51
Modify the ".dump" command on the CLI so that it always issues a PRAGMA foreign_keys=OFF at the top of the output. (check-in: 0755b9b6 user: drh tags: trunk)
14:45
Change the version number to 3.6.19. Fix a couple of incorrect testcase() macros associated with the new IS and IS NOT operators in expr.c. (check-in: e3b73394 user: drh tags: trunk)
13:59
Disallow using the implicit rowid column as the parent key of an FK constraint. (check-in: a5f7e71f user: dan tags: trunk)
13:39
Add test cases for the IS and IS NOT operator. (check-in: 101ed58c user: drh tags: trunk)
12:06
Add extra tests for foreign key support. (check-in: 7d086afe user: dan tags: trunk)
08:43
Add missing comments to fkey.c. Also, change the terminology used for comments and names in fkey.c from "referenced/referencing" to "parent/child". This is arguably less correct, but is easier to follow. (check-in: 540c2d18 user: dan tags: trunk)
03:01
Do not run ON UPDATE actions of a foreign key constraint unless at least one column value really does change. (check-in: 71ac8e28 user: drh tags: trunk)
02:29
Generalize the IS and IS NOT operators so that their right-hand side can be an arbitrary expression and not simple the constant NULL. They work like = and <> except that NULL values compare equal to one another an unequal to everything else. (check-in: 98853f61 user: drh tags: trunk)
2009-09-22
20:08
Factor the UMINUS and UPLUS tokens out of the parser so that the parser tables can go back to using 8-bit values instead of 16-bit values. (check-in: 3fc938c9 user: drh tags: trunk)
19:53
The NO ACTION action really should be no-action and not RESTRICT. (check-in: 55b263fa user: drh tags: trunk)
16:55
Fix another OOM related problem in fkey.c. (check-in: e2bc51bc user: dan tags: trunk)
16:08
Fix a problem with ON DELETE SET DEFAULT actions. (check-in: 94069950 user: dan tags: trunk)

2009-09-21
18:56
Fix a problem with foreign key constraints that map from and IPK column. (check-in: 84129052 user: dan tags: trunk)
16:34
Fix compilation with both OMIT_UTF16 and ENABLE_STAT2 defined. Ticket [56928bd084]. (check-in: cd850d49 user: dan tags: trunk)

2009-09-17
00:41
When coding a trigger, assume that the "oldmask" requires all columns until we know otherwise. That pessimistic assumption assures that all necessary parameters are available on a cascading delete trigger. Ticket [e25d9ea771f] (check-in: 03e464be user: drh tags: trunk)
2009-09-14
23:47
Make sure sufficient space is allocated for at least one VDBE cursor when autoincrement is used. Ticket [a696379c1f088]. (check-in: 2b2a1ef7 user: drh tags: trunk)
2009-09-11
18:28
Set the execute permission bit on "configure". (check-in: f8c02b2b user: drh tags: trunk)
17:59
Make sure the (unsupported) configure script in the source tree has execute permission prior to constructing a tarball. Ticket [65bbb65a47ce]. (check-in: 5e0e941f user: drh tags: trunk)
14:05
Version 3.6.18 (check-in: b084828a user: drh tags: trunk, release)
2009-09-10
22:30
Omit the mutexIsInit test variable when mutexes are disabled. (check-in: 3ea10434 user: drh tags: trunk)

Make sure the threadsOverrideEachOthersLocks variable is only referenced by linux systems on a threadsafe compile. (check-in: e9d064bd user: drh tags: trunk)
19:09
Cleanup of warnings on MSVC build. (check-in: 5588cc96 user: shane tags: trunk)
18:26

2009-09-09
18:46
Trying to open a transaction in one thread and close it in another is a misuse with LinuxThreads. Doing so may cause memory and file-descriptors to be leaked. Update an assert() and some test cases to account for this. (check-in: ef99eb57 user: dan tags: trunk)
16:10
Suppress some harmless compiler warnings. (check-in: f0c72a53 user: drh tags: trunk)
15:29

15:06
Add some tests that involve BEFORE UPDATE or BEFORE DELETE triggers messing with the row being updated or deleted. SQLite behaviour in this scenario is undefined, so the tests just check that the behaviour is relatively sane and there are no crashes. (check-in: 9a4c59a2 user: dan tags: trunk)
14:48
Update the README file to state that TCL is required in order to run the makefiles for SQLite. Ticket [7d96113ff]. (check-in: ba20091a user: drh tags: trunk)
14:17
Added SQLITE_OPEN_SHAREDCACHE and SQLITE_OPEN_PRIVATECACHE flags as possibilities to sqlite3_open_v2(), to override the global shared cache mode setting. Ticket [9fd0bc36639c15] (check-in: f509eb8b user: drh tags: trunk)
12:41
Increase the size of bitvec objects to 1024 bytes on 64-bit systems. (check-in: f1272b90 user: drh tags: trunk)
11:43
Add a test case to show that 29ab7be99f is fixed. (check-in: 135d656a user: dan tags: trunk)
11:37
Add a complicated assert() to check that statement transactions are opened when required. (check-in: 28aa1f4e user: dan tags: trunk)
2009-09-08
19:15
Combine the OP_Statement and OP_Transaction opcodes. (check-in: aec9dbd8 user: dan tags: trunk)

If recursive-triggers are enabled, fire DELETE triggers if database rows are removed as a result of OR REPLACE conflict resolution. (check-in: 85cb0c94 user: dan tags: trunk)
13:40
Additional simplifications in support of structural testing. (check-in: 4ab8c841 user: drh tags: trunk)
02:27

01:14
Code simplifications, especially to the pseudo-table logic, and comment improvements. (check-in: 52449a95 user: drh tags: trunk)
2009-09-07
18:14
Add the SQLITE_LIMIT_TRIGGER_DEPTH option to sqlite3_limit(). (check-in: d7dc8b43 user: drh tags: trunk)
17:41
Merge 1958db4493 and 26cd015c0e. (check-in: ecbe0832 user: dan tags: trunk)
17:32
Fix a bug where a condition was incorrectly being compiled out when SQLITE_OMIT_VIRTUALTABLE was defined. (check-in: 1958db44 user: dan tags: trunk)
04:38
Warning cleanup from the MSVC compile. (check-in: 26cd015c user: shane tags: trunk)
03:48
Attempt to handle numbers at the limits of the IEEE 754 range better (nan.test now passes). (check-in: 2a74ae19 user: shane tags: trunk)
02:46
Changes to internal AtoF to improve "accuracy" when measured against built-in GCC atof(). (check-in: 438e1577 user: shane tags: trunk)
2009-09-03
19:43
Fix a VDBE stack overflow issue with the UPDATE statement. (Leaf check-in: 715cecb8 user: drh tags: branch-3.3.6)
16:23
Add the "unix-wfl" VFS that does whole-file locking in order to help NFS do better cache coherency. (check-in: 2aeab80e user: drh tags: trunk)
01:18
Do not reuse function parameters in subsequent expressions since the function call might have triggered a text encoding change. Fix for ticket [2ea2425d34be]. (check-in: f22e3887 user: drh tags: trunk)
2009-09-02
19:04
