14:18
Add a guard #ifndef to test_intarray.h to prevent harm if it is #included more than once. Add a comment on the closing #endif of the guards on sqlite3.h and test_multiplex.h. (check-in: 0ad83ceb user: drh tags: trunk)
01:18

07:45
More than double the speed of the resolveP2Values() routine in vdbeaux.c by moving from an extended if-else on every opcode to a switch.

2013-08-01
22:27
Fix the CREATE INDEX statement so that trying to create a TEMP index on a non-TEMP table throws an error rather than segfaulting. (check-in: e3c8935f user: drh tags: trunk)
22:26
Fix an incorrect expected result in a test case in corruptG.test. (check-in: 6913831a user: drh tags: trunk)
20:26
Fix a potential buffer overread in sqlite3VdbeRecordCompare() when a serial_type specifies a field that starts in bounds but is much too large for the allocated buffer. Mostly harmless. The overread is unlikely to go more than one or two bytes past the end of the buffer. (check-in: e436b2f4 user: drh tags: trunk)
19:17
Make sure signed integer overflow does not cause a segfault while attempting to read a corrupt database where the header size varint on a record is larger than the maximum 32-bit signed integer. (check-in: c3baca99 user: drh tags: trunk)
17:43
Add test case for the problem fixed by [127a5b776d]. (check-in: 65816718 user: dan tags: trunk)
17:21
An improved method for avoiding the use of the STAT3 samples to compute the estimated number of outputs when the left-most index is equality constrained. This check-in undoes the previous fix and applies a new one. (check-in: 127a5b77 user: drh tags: trunk)
16:52

2013-07-31
23:28
Limit the number of memset() calls used when determining a temporary file name on Windows. Also, fix a harmless compiler warning. (check-in: 136fc293 user: mistachkin tags: trunk)
23:22
Add logic to the query planner to only use partial indices if the WHERE clause constrains the search to rows covered by the partial index. This is just infrastructure. The key routine, sqlite3ExprImpliesExpr(), is currently a no-op so that partial indices will never be used. (check-in: 8ca3eac1 user: drh tags: partial-indices)
22:39
Slight modifications to path name translation handling for Cygwin. (check-in: 33ba1f4c user: mistachkin tags: trunk)
22:27
Use a new error code to represent a failure to get the configured temporary directory on Windows. (check-in: c93d891b user: mistachkin tags: trunk)
19:55
The MAX_PATH constant in windows is measured in characters, so multiple by 3 to get the number of bytes assuming worst-case UTF8 pathnames. (check-in: bb06e157 user: drh tags: trunk)
19:05
Resolve names in CREATE INDEX WHERE clauses and detect errors. Disallow expressions that contain variables, subqueries, or functions. The expression is still not used for anything, however. still unused. (check-in: f2aa7842 user: drh tags: partial-indices)
18:12
Here begins an experimental branch for exploring the idea of a partial index. This check-in is able to parse a WHERE clause on a CREATE INDEX statement, but does not actually do anythingn with that WHERE clause yet. (check-in: 6794b2dc user: drh tags: partial-indices)
2013-07-30
15:10

In main.mk, always recompile vdbe.o and parse.o first, since changes to either parse.y or vdbe.c will cause all files to be recompiled and if there are syntax errors in vdbe.c or parse.y we want to hit them early in the compile process. (check-in: a94a66d1 user: drh tags: trunk)

Update the URI filename parser to allow (and ignore) authority names in unix and to pass the authority through to the OS on windows, as this appears to be what web-browsers are doing. (check-in: 74c12dee user: drh tags: uri-enhancement)

Ensure that all auxiliary data registered by calls to sqlite3_set_auxdata() is destroyed when the VM is halted. Partial fix for [406d3b2ef9]. DRH adds: Stray text accidentally inserted into vdbe.c just prior to the commit breaks the build. (check-in: 71effa59 user: dan tags: typo)

Add the experimental "query_only" pragma. (check-in: 6557c407 user: drh tags: trunk)
15:03
Add the "defer_foreign_keys" pragma and the SQLITE_DBSTATUS_DEFERRED_FKS value for sqlite3_db_status(). This is a cherry-pick of a sequence of five checkins in the sessions branch between [1d44e5d3c2] and [d39e65fe70]. (check-in: 527121ac user: drh tags: trunk)
13:49
Remove the undocumented sqlite3_foreign_key_check() API and replace it with sqlite3_db_status(db, SQLITE_DBSTATUS_DEFERRED_FKS, ...). Add test cases for the new functionality. (check-in: d39e65fe user: drh tags: sessions)

Experimental "PRAGMA query_only=BOOLEAN" statement that is able to turn write capabilities on and off. (Closed-Leaf check-in: ece960c4 user: drh tags: query_only)
03:05
Run progress callback checks less frequently in the main VDBE evaluation loop. This makes up for the extra CPU cycles used to increment the cycle counter for SQLITE_STMTSTATUS_VM_STEP. (check-in: 3e8b0201 user: drh tags: trunk)

Fixes for test cases running in the "mmap" permutation. (check-in: cdb97d41 user: dan tags: trunk)
17:57
Drop any existing mapping of the database file when exiting the pager "error state", as it may at this point be too large for the database file. Do not invoke file-control MMAP_SIZE if the database file handle does not support xFetch and xUnfetch (on the grounds that xUnfetch(0) calls to invalidate the mapping cannot be made).

Fix a bug preventing some FK constraint checking from being deferred until the end of changeset application. (check-in: 1452defb user: dan tags: sessions)
2013-07-03
19:53
Experimental change to the handling of foreign key constraint violations when applying a changeset: all foreign keys, immediate and deferred, are deferred until the end of the transaction (or sub-transaction) opened by the sqlite3changeset_apply(). A single call to the conflict-handler (if any) is made if any FK constraint violations are still present in the database at this point. The conflict-handler may choose to rollback the changeset or to apply it, constraint violations and all. (check-in: 1d44e5d3 user: dan tags: sessions)
