19:12		Avoid casting a value larger than 2^31 to a (size_t) or (SIZE_T) on systems where it is a 32-bit type. (check-in: b26d7a1c7b user: dan tags: trunk)
19:06		On Windows, avoid casting a value larger than 2^31 to a (SIZE_T) on systems where it is a 32-bit type. (Leaf check-in: f08d63b413 user: mistachkin tags: mmap-size-limit)
18:54		Fix a problem with handling SQLITE_FCNTL_MMAP_SIZE requests with a negative parameter in os_unix.c. (check-in: 4249fcf7b0 user: dan tags: mmap-size-limit)
18:51		• Edit [46c3085dcad6372a|46c3085dca]: Move to branch mmap-size-limit. (artifact: 8e84a1221b user: dan)
18:51		• Edit [46c3085dcad6372a|46c3085dca]: Change background color to "#ffc0ff". Add tag "mmap-size-limit". (artifact: b4eb232879 user: dan)
18:27		Update bigmmap.test to account for builds that use "-DSQLITE_MAX_MMAP_SIZE=<integer-constant>LL". (check-in: 7c8b6f1cac user: dan tags: mmap-size-limit)
18:13		Avoid casting a value larger than 2^31 to a (size_t) on systems where it is a 32-bit type. (check-in: 46c3085dca user: dan tags: mmap-size-limit)
17:28		Fix an out-of-order test number. (check-in: 38f30091f9 user: mistachkin tags: trunk)
17:14		Add new test file "bigmmap.test". For testing builds with -DSQLITE_MAX_MMAP_SIZE > 2GB. (check-in: 1744706279 user: dan tags: trunk)
14:15		Update this branch with latest trunk changes. (check-in: 17bc7ded07 user: dan tags: server-process-edition)
14:06		Fix a bug on this branch involving mmap mode and readonly transactions. (check-in: 355c594e82 user: dan tags: server-process-edition)

18:52		Fix documentation typos. No changes to code. (check-in: ebc396a19f user: drh tags: trunk)

2015-08-07
20:57		Enhance the query planner so that it is able to use partial indexes that use AND-connected terms in the WHERE clause. (check-in: 065765902d user: drh tags: trunk)
20:06		Add a specially formatted comment to shell.c to make it easier for scripts to edit. No code changes. (check-in: 6d47b35ad1 user: dan tags: trunk)
09:42		Within a write-transaction on a wal database in mmap mode, check the page-cache for an entry before the wal file. This can be faster if the wal file is very large. (Leaf check-in: 3a82c8e6cb user: dan tags: mmap-wal-bigtrans)

2014-08-07
20:42		When the estimated sorting cost overwhelms the estimated lookup cost, ensure that lookup costs are still taken into account when selecting a lookup algorithm. (check-in: 2af630c572 user: drh tags: trunk)
20:37		Clarify the computation of compatible isOrdered by in the plan solver of the query planner. (Closed-Leaf check-in: b5e8fd575a user: drh tags: query-planner-fix)
20:25		Remove the extraneous debugging printf() from the previous check-in. (check-in: 8f04d2c008 user: drh tags: query-planner-fix)
20:24		• Edit [ec5d84ba69c100d9|ec5d84ba69]: Move to branch query-planner-fix. Edit check-in comment. (artifact: b217a2d52c user: drh)
18:47		Add "segment promotion" to fts5. This prevents the FTS index from growing indefinitely as data is added and deleted. (check-in: ba359d78e1 user: dan tags: fts5)
16:50		Oops! This check-in was on trunk. But it contains a debugging printf(). Original comment: When the estimated cost to do a sort overwhelms the estimated cost to do individual table lookups, make sure that the table lookup costs are still taken into consideration when selecting the lookup algorithm. (check-in: ec5d84ba69 user: drh tags: query-planner-fix)

2009-08-07
16:56		Enhancement to (6844). If sqlite3_exec() is to return SQLITE_NOMEM because it fails to allocate space for an error message, set the database error-code to SQLITE_NOMEM too. (CVS 6962) (check-in: 8293fa19c0 user: danielk1977 tags: trunk)
