20:24
Bare identifiers in ORDER BY clauses bind more tightly to output column name, but identifiers in expressions bind more tightly to input column names.

2013-08-05
22:05
Performance optimization: Avoid calling convertCompoundSelecctToSubquery() on queries that do not use the UNION, EXCEPT, or INTERSECT operators. check-in: c589b2fe user: drh tags: trunk
21:54
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

2013-08-01

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

15:54
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
2013-07-25

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.
