6 check-ins related to "in-early-out-fail"

2020-09-01
00:09
Minor changes - fix a compiler warning and add an assert(). (Closed-Leaf check-in: 07222dce user: drh tags: in-early-out-fail)

19:58
Merge the SEEK_COUNT instrumentation enhancement from trunk. (check-in: 689ede95 user: drh tags: in-early-out-fail)
19:19
An attempt to improve the performance of the IN-early-out optimization (see check-in [09fffbdf9f2f6ce3]) by avoiding unnecessary calls to the b-tree search algorithm in OP_IfNoHope when the index key is at hand and the same answer can be obtained by doing a quick key comparison. Update: Experiment did not work out. (Closed-Leaf check-in: 8301da31 user: drh tags: branch-3.28-in-early-out-fail)
18:49
New test-control that returns the number of calls to sqlite3BtreeMovetoUnpacked() on the main database and then resets the counter. This only works for SQLITE_DEBUG builds. (check-in: dca5b919 user: drh tags: trunk)
16:31
An attempt to improve the performance of the IN-early-out optimization (see check-in [09fffbdf9f2f6ce3]) by avoiding unnecessary calls to the b-tree search algorithm in OP_IfNoHope when the index key is at hand and the same answer can be obtained by doing a quick key comparison. Update 2020-08-31: This experiment did not work out. A better approach is now on trunk. (check-in: e9d983c6 user: drh tags: in-early-out-fail)
12:29
Fix the documentation for the OP_IdxGT family of opcodes to show that the P5 operand is not used. (check-in: 62f7d2a6 user: drh tags: trunk)
