For the vtshim module, always zero out the xChildDestroy function pointer after calling it. check-in: 240f7252 user: mistachkin tags: trunk
19:11
Factor all KeyInfo object allocations into a single function: sqlite3KeyInfoAlloc(). Always allocate enough space so that sqlite3VdbeRecordCompare() can avoid checking boundaries and hence run faster. check-in: 7301bedd user: drh tags: trunk
15:32
Improve performance of sqlite3VdbeRecordCompare() by using an approximation that might give false negatives and only running the more expensive exact subexpression if the approximation fails. check-in: 28979dcd user: drh tags: trunk

Add a missing '#include "tcl.h"' to test_rtree.c. check-in: 4b8b426f user: drh tags: trunk

Fix typos in documentation for SQLITE_DBSTATUS_DEFERRED_FKS . No changes to code. check-in: f3efbfcd user: drh tags: trunk
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
Avoid using left-most column STAT3 samples if the left-most column has an equality constrain and there are inequality constraints on the second column. check-in: 31b4e63b user: drh tags: trunk
16:02
Fix bug in the logic that determines the end of a CREATE INDEX statement. Added a VACUUM test case that exposed the bug. check-in: 2e3df0bc user: drh tags: partial-indices

More test cases and corresponding bug fixes. check-in: 0c8cfdfa user: drh tags: partial-indices

Test cases and bug fixes for the partial index logic. check-in: 6b73ae7c user: drh tags: partial-indices

Add the logic to keep partial indices up to date through DML statements and when new partial indices are created. This new logic is untested except to verify that it does not interfere with full indices. check-in: fb9044d1 user: drh tags: partial-indices

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

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

For the MSVC makefile, recompile vdbe.lo and parse.lo first. check-in: 9e819f0f user: mistachkin tags: trunk

Comment and preprocessor macro cleanup. check-in: c0809b5e user: drh tags: trunk
13:51
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

In the command-line shell, work around the fact that popen() and pclose() are not defined in stdio.h. in C89 and later. check-in: 8bcbb33f user: drh tags: trunk

Enhance the progress handler so that it keeps track of the number of VDBE cycles across sqlite3_step() calls and issues callbacks when the cumulative instruction count reaches threshold. check-in: 4698a82e user: drh tags: trunk

Fix a typo in the previous commit. Closed-Leaf check-in: cd9096e6 user: dan tags: typo
17:12
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
14:50
Fix a 8-byte alignment problem in the query planner that might cause problems on sparc when compiled with -m32. check-in: 5dcffa67 user: drh tags: trunk
14:16
Documentation changes to warn that sqlite3_set_auxdata() might call the destructor even before it returns. Also fix the regexp extension to deal with that case. Ticket [406d3b2ef91c]. check-in: 7acc8cd3 user: drh tags: trunk

Change the description of how sqlite3_progress_handler() works so that the N parameter is "approximate". This aligns with the current implementation. This is a documentation change only. No changes to code. check-in: 7d829bde user: drh tags: trunk
15:22
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

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
