Try to fix a harmless compiler warning reported by ICC. Leaf check-in: 7f41b44ca2 user: drh tags: trunk

Fix a resource leak in fts5 that could occur if an auxiliary function is called from within a query that does not use the full-text index. check-in: b528bdcd45 user: dan tags: trunk

2019-10-17
15:41
Avoid an infinite loop in fts3/4 incremental-merge in the case where the lowest level in the database contains segments but no data (because there is a delete-marker for each valid entry). Fix for [bf1aab89]. check-in: 35beaee059 user: dan tags: trunk

16:41

15:57
Fix the OP_SeekRowid opcode so that it works correctly with a Real argument without damaging the value in the register that is the argument. Ticket [b2d4edaffdc156cc]. Test cases in TH3. check-in: b02630fe6e user: drh tags: branch-3.30
15:48

15:26
Disallow fts5 page sizes greater than 65536 bytes - as there are 16-bit offsets used in the page header. Fix for [81a7f7b9]. check-in: 75775c5ab4 user: dan tags: trunk
15:08
Remove the "fastfuzztest" makefile target. Use only "fuzztest". check-in: e17571c789 user: drh tags: trunk

2019-10-05
19:53
Omit the check for conflicting shared-cache locks in sqlite3Prepare() if the database connection uses no shared cache. We might be able to go back and remove this code completely, due to the newer Schema.iGeneration logic, but that will take more analysis. This check-in gives the speed benefit but not the reduction in code size. check-in: 0b73a09270 user: drh tags: trunk
