When estimating the number of rows scanned using data from the sqlite_stat4 table, avoid allocating UnpackedRecord and KeyInfo structures until they are definitely required. check-in: 353950a5 user: dan tags: sqlite_stat4
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

When possible, use the multi-column samples in sqlite_stat4 to estimate the number of index rows scanned by a query plan. check-in: 2973f5ca user: dan tags: sqlite_stat4
19:18
Fix a test case related to partial indices so that it works even if STAT3 is disabled. check-in: 153c6450 user: drh tags: trunk
18:35
Adjust #ifdefs in test_autoext.c so that it compiles with SQLITE_OMIT_LOAD_EXTENSION. Fix compiler warnings in two other test modules. No changes to the core. check-in: 89930ea3 user: drh tags: trunk

Update the configure script to use the latest version number (3.8.0). check-in: 52e8ec5e user: drh tags: trunk

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. Opcodes are reordered in mkopcodesh.awk to put the switched opcodes close together, for additional performance and to reduce code footprint. check-in: 924f7e4d user: drh tags: trunk

Performance optimization: Avoid calling convertCompoundSelecctToSubquery() on queries that do not use the UNION, EXCEPT, or INTERSECT operators. check-in: c589b2fe user: drh tags: trunk

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
19:04
Modify the vdbe code generated by ANALYZE to use fewer memory cells and cursor slots. check-in: 4a51cf28 user: dan tags: sqlite_stat4
18:00
Use N separate cursors when scanning an index with N columns to collect sqlite_stat4 data. This fixes a problem with collecting incorrect nEq values from multi-column indexes. check-in: 3a71afe6 user: dan tags: sqlite_stat4
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

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

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

Slight modifications to path name translation handling for Cygwin. check-in: 33ba1f4c user: mistachkin tags: trunk

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

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

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
