18:31
Merge all recent changes from trunk. check-in: 3d04b2cd user: drh tags: apple-osx
18:24
In the output of the ".dump" command in the CLI, quote newline and carriage-return characters using the char() function, so that they do not get eaten by end-of-line processing logic in the OS or in other command-line utilities and/or libraries. check-in: 68f6dc7a user: drh tags: trunk
17:37
Fix the sqlite3TreeViewSelect() routine so that it works with a null pointer to the Select object. check-in: 9034cf7e user: drh tags: trunk

Fix a segfault that could occur following an OOM error in the flattenSubquery() routine. check-in: c6dda3f7 user: dan tags: trunk
13:45
In the OSSFuzz test module, invoke the progress handler much more frequently so that timeouts are detected punctually even if the test script is running opcodes that individually take a long time (for example, an OP_Function opcode that invokes "randomblob(1.5e6)"). check-in: f3b6959c user: drh tags: trunk
2017-03-12

01:56
The output of the ".dump" command in the CLI quotes newline and carriage-return characters using "char(10)" and "char(13)". Closed-Leaf check-in: 8b2954dd user: drh tags: string-quoting-dump
00:46

14:36
Enhance the ".stats" dot-command in the CLI to use sqlite3_status64() instead of sqlite3_status(). check-in: 118f5c05 user: drh tags: trunk

2017-03-09
22:00
Remove the test/dbselftest.c program. In its place, add the ".selftest" command to the CLI. The new CLI version is .selftest is slightly different in that it uses SHA3 hashing instead of SHA1, so the new is subtly incompatible with the old. check-in: f4fcd46f user: drh tags: trunk
18:13
Fix the ".dump" command to correctly extract tail data from corrupt WITHOUT ROWID tables. check-in: 6c627e50 user: drh tags: trunk
16:32
Add the --recovery-mode option to the CLI ".dump" command. This involves enhancing the "PRAGMA reverse_unordered_selects" command to accept a "TOGGLE" option. Recovery mode used to be always on. Now it is opt-in. Not sure this is the correct approach. Also not sure if TOGGLE is a good feature to have on boolean PRAGMA statements. Closed-Leaf check-in: 5dc82a15 user: drh tags: dump-recovery
13:50
Begin moving separate boolean variables in the ShellState object of the CLI into the shellFlgs bitmask. check-in: 50eec5d9 user: drh tags: trunk

16:10
Add the ".sha3sum" command to the CLI - used to compute a cryptographic hash of the content of a database file or of individual tables with in that file. check-in: fc663799 user: drh tags: trunk
15:03
Improved comments explaining the sha3_query() format. Fix a performance #ifdef error in the sha3 implementation. check-in: 54ef7abd user: drh tags: trunk

14:47
