Test for schema corruption is reachable after all. (check-in: 2032236cce user: drh tags: trunk)

Provide an alternative "guaranteed-safe" method for overwriting the WAL index on recovery, in case some platform is found for which memcpy() cannot do this safely. (check-in: 168cccbabb user: drh tags: trunk)

Fix unreachable branches. (Closed-Leaf check-in: 905752da98 user: drh tags: larger-databases)
2020-07-29
16:18
Dozens and dozens of typo fixes in comments. This change adds no value to the end product and is disruptive, so it is questionable whether or not it will ever land on trunk. (Leaf check-in: a80ae2c98b user: drh tags: typos)
12:23

If a writer crashes in WAL mode and leave the SHM file in an inconsistent state, subsequent transactions are now able to recover the SHM file even if there are active read transactions. (check-in: ee8a108058 user: drh tags: trunk)
17:17
Add an sqlite3FaultSim() to make an OOM case more accessible and remove the ALWAYS() on the conditional that is false when the OOM actually occurs. (Closed-Leaf check-in: 2a251af84f user: drh tags: unlocked-recovery)
2020-07-27
20:16
On recovery, always overwrite the old with the new, even if they are the same. Add ALWAYS() macros on branches currently thought to be unreachable, pending additional testing. (check-in: 7052cf1d53 user: drh tags: unlocked-recovery)

2020-07-25
20:16
When trying to read the index header, accept either of the two headers that have a valid checksum after 15 attempts to get exactly matching headers fail. (Closed-Leaf check-in: 3549faefea user: drh tags: more-aggressive-wal-recovery)

2020-07-23
20:37
Turns out this is an aliasing bug in SQLite, not a GCC bug. Was: Work-around for what appears to be another GCC bug - this one for GCC 8.3.0 on ARM. See the [https://sqlite.org/forum/forumpost/d44eb2fc44|SQLite forum post] for discussion. (Closed-Leaf check-in: 40c44d3810 user: drh tags: mistake)
18:03
Add the OMIT_ZLIB compile-time option to sessionfuzz.c. (Originally checked into the wrong branch.) (check-in: 6019bf8a2d user: drh tags: trunk)

14:27
Merge fixes from trunk. (check-in: dd39418ee4 user: drh tags: larger-databases)
14:12
An ORDER BY clause can slip into an SRT_Upfrom query via the query flattener, even without the SQLITE_ENABLE_UPDATE_DELETE_LIMIT compile-time option. So always enable the code to deal with that case. (check-in: 6a3111cd06 user: drh tags: trunk)
13:45
Fix another case where a corrupt record could cause an assert() to fail in fts3. (check-in: 28515bbbae user: dan tags: trunk)
09:14
Merge support for partial integrity checks. (check-in: b5443b47af user: drh tags: larger-databases)
00:45

21:05
Disable rootpage bounds checking when the SQLITE_TESTCTRL_EXTRA_SCHEMA_CHECKS setting is off, to facilitate reaching obscure error states during testing. (Closed-Leaf check-in: d7dd4fc464 user: drh tags: rootpage-bounds-check)
20:12
Improvements to rootpage bounds checking during schema parse. (check-in: 75599a9731 user: drh tags: rootpage-bounds-check)

18:25
Add the sqlite3Int64ToText() routine and use it to convert integers to text, as it is much faster than the generic text formatter. (check-in: 14eed318aa user: drh tags: trunk)
2020-07-20
23:33
Fix the ".read" command so that it gives an error when its argument is a directory. See [https://sqlite.org/forum/forumpost/4c53c434ca|forum message 4c53c434ca]. (check-in: 6d258c3c7e user: drh tags: trunk)
