14 check-ins using file src/os_unix.c version abeb9d54

2014-01-06
18:32
Start a new experimental branch for support of Oracle-style CONNECT BY syntax. (Closed-Leaf check-in: 4365ddd6 user: drh tags: connect-by)
2014-01-04
20:00
Fix an typo that breaks the build when SQLITE_ENABLE_TREE_EXPLAIN is defined. (check-in: f461e2b3 user: drh tags: trunk)
19:58
Add the usual "fts3" prefix to new static method setEstimatedRows() in fts3.c. This fixes a problem when compiling the amalgamation, as the r-tree module also contains a static method named setEstimatedRows. (check-in: d6fcfc88 user: dan tags: trunk)
19:27
Avoid redundant register loads during index key generation when doing a DELETE or INTEGRITY_CHECK on a table with multiple indices. (check-in: 8f6e6149 user: drh tags: trunk)
16:49
Omit OP_Close operations that occur immediately prior to OP_Halt and which cannot be jumped over. (check-in: 874b7e99 user: drh tags: trunk)
15:17
Improvements to the column-cache for nested AND/OR operators. (check-in: 4e725f53 user: drh tags: trunk)
14:46
Have FTS assign extremely high costs to plans that feature unusable MATCH constraints. This discourages the planner from choosing such plans, which lead to "unable to use function MATCH in the requested context" errors. (check-in: fa8be488 user: dan tags: trunk)
14:42
Instead of having the planner ignore plans with unusable MATCH constraints, have FTS assign extremely high costs to such plans in order to discourage the planner from using them. (Closed-Leaf check-in: 24f84b38 user: dan tags: avoid-unusable-match)
14:16
Have the planner detect cases where a MATCH constraint is applied to a virtual table, and ignore any plans that do not allow the virtual table implementation to implement the MATCH filtering. (check-in: 19f3208b user: dan tags: avoid-unusable-match)
2014-01-03
16:03
Avoid some unnecessary OP_SCopy operations when inserting into a table with multiple indices. (check-in: 429018b1 user: drh tags: trunk)
2014-01-02
21:05
Try to factor constant subcomponents of the WHERE clause out of the loop. (check-in: 9d05777f user: drh tags: trunk)
19:35
Avoid unnecessary affinity transformations when building indices using data from a table. (check-in: 10d85135 user: drh tags: trunk)
17:57
Be more aggressive in optimizing constant conditional expressions. (check-in: b7e39851 user: drh tags: trunk)
2014-01-01
15:18
Try to detect process ID changes due to fork() calls in os_unix.c and reset the PRNG when a process ID change is detected. (check-in: e1eba1fb user: drh tags: trunk)
