In the command-line shell, if three or more interrupt signals (control-c) are received in a row without a response from sqlite3_interrupt() then call exit(1) immediately.

Repurpose the SQLITE_TESTCTRL_FAULT_INSTALL test-control to register a callback to be invoked by sqlite3FaultSim(). That test-control has been unused since 2008-06-20 and was never used in any official release. check-in: 0d43a7ad user: drh tags: trunk

Fix a problem to do with loading the value of the FTS automerge setting from the database. check-in: 7268119f user: dan tags: fts4-experimental
15:58
Fix various problems to do with segment promotion. Add test file fts4growth2.test, containing tests to check that the FTS index does not grow indefinitely as the table is updated.

12:18
Fix an incorrect check for API misuse. check-in: 856400dc user: drh tags: apple-osx

2014-05-08
23:01
Initial attempt to merge in all trunk changes over the previous 1.5 years. This check-in compiles but there are compiler warnings and "make test" segfaults after only running a few test modules. check-in: 9411d7dc user: drh tags: apple-osx
2014-05-07
21:16

18:21
Ensure that the sqlite3StrAccumAppend() routine is never called with a NULL second argument. Doing so is harmless when N==0, but it causes an assert() to fail that was placed to quiet static analyzers. Closed-Leaf check-in: f03fbf37 user: drh tags: tkt-55746f9e
17:19
Make sure the group_concat() function returns an empty string, not a NULL, if it has at least one input row. Fix for ticket [55746f9e65f8587]. check-in: 0deac873 user: drh tags: tkt-55746f9e

22:24
Change a while-loop into a do-loop in sqlite3VdbeRecordCompare() and add an assert() to verify that the do-loop really is appropriate. This gives about a 10% performance boost in that routine, or a 0.9% boost overall. check-in: 011a6be4 user: drh tags: trunk
21:49
Clarify docs for the SQLITE_CONFIG_WIN32_HEAPSIZE option. Closed-Leaf check-in: 51e87607 user: mistachkin tags: winHeapSize

20:14
Return an SQLITE_CORRUPT error if the content size field of a table record extends off the end of a page. Closed-Leaf check-in: b48c4e40 user: drh tags: btree-optimization
17:38
Uses shifts rather than division for arithmetic on the cell indices, since those indices are always non-negative. check-in: 5bf2a3fe user: drh tags: btree-optimization
16:52
Optimize the skipping of the payload size field when doing a binary search for a rowid. check-in: 55e5bfa2 user: drh tags: btree-optimization
16:23
Arrange for sqlite3BtreeMovetoUnpacked() to always leave the cursor cell parse cache invalidated. This fixes issues with previous check-ins on this branch and also runs faster. check-in: a7467560 user: drh tags: btree-optimization
15:01
More optimizations to sqlite3BtreeMovetoUnpacked(). But there are failures in TH3. Committing this intermediate state to facilitate bisecting. check-in: f80497be user: drh tags: btree-optimization

Add the --scratch parameter to speedtest1. Improved error messages when misconfiguring memory parameters in speedtest1. check-in: 8f3c767a user: drh tags: trunk
00:46
The MEMSYS5 algorithm does not have to return the block with the lowest address. Any block of the appropriate size will do. Use the first block found on the freelist for the appropriate size for a performance improvement. check-in: 12e612e8 user: drh tags: trunk
2013-11-23
22:45
A much simpler fix is to simply change MEMSYS5 so that it takes any free block of the appropriate size (the first on the list of free blocks) rather than searching for the one with the smallest address. This is also faster than using the min-heap algorithm. Need to research to verify that the allocator still satisfies the Robson proof, however. Closed-Leaf check-in: 8191b512 user: drh tags: memsys5-performance
21:29
Add newlines at the end of some error messages in speedtest1. check-in: 6b98f0af user: drh tags: trunk

17:24
Make sure the OP_Next and OP_NextIfOpen opcodes are numbered close together for efficiency in switch() statements. OP_Prev and OP_PrevIfOpen too. check-in: d4ccf0f5 user: drh tags: trunk
