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
14:30
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
20:28
Fix a possible NULL pointer dereference in following an OOM error in sqlite3ExprIsInteger(). Problem found by OSS-Fuzz. check-in: 5ec655e8 user: drh tags: trunk

2017-03-11
13:02

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
01:05

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

17:56
In the ".sha3sum" command, if there is a LIKE pattern, show the hashes for each table separately. Without a LIKE pattern, show a single hash over the entire database. check-in: 30f87883 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

21:51
If a reprepare is needed after binding to a variable with a number larger than 32, set only the high-order bit of the Vdbe.expmask rather than setting all bits. This could potentially result in fewer false-positive reprepares. check-in: 45797fee user: drh tags: trunk
21:36
Remove an redundant function call from the date/time function implementation. check-in: 4a04c48a user: drh tags: trunk

2017-03-02
23:40

14:51
When saving the state of an RBU update in the incremental-checkpoint phase, sync the database file. Otherwise, if a power failure occurs and the RBU update resumed following system recovery, the database may become corrupt. check-in: edee6a80 user: dan tags: trunk
14:17

2017-02-22
20:24
Change the name of the analyze_as_needed pragma to "optimize". Enhance the comment (which will become documentation, assuming these changes land on trunk) to explain that the optimize pragma is likely to be enhanced in various ways in future releases and that applications should not depend upon the current behavior. check-in: 9fced545 user: drh tags: auto-analyze
19:49
Merge integrity_check and other improvements from trunk. check-in: fe073905 user: drh tags: auto-analyze

02:04
Fix a test case that was made to fail by the LIKE optimization enhancement in check-in [158290c0ab] but which went unnoticed because test builds were running with ICU enabled and ICU disables the LIKE optimization. check-in: 218b2bbb user: drh tags: trunk
01:43
Enable the ".wheretrace" and ".selecttrace" extensions in the command-line shell when compiled on Windows using DEBUG=3 or higher. Fix a harmless warning in the shell that comes up when compiled this way. check-in: 8a03be1d user: drh tags: trunk
2017-02-16
20:52
Change the name of WhereInfo.pDistinctSet to pResultSet, since it is now used for more than just DISTINCT processing. check-in: 9fc5cd50 user: drh tags: trunk

18:30
Minor enhancement to mutex tracing on Win32. check-in: 830b9235 user: mistachkin tags: trunk
15:09
Remove the CLANG_VERSION macro, since we have learned that version numbers in clang are "marketing" and are inconsistent and unreliable. Builds using clang will still use the GCC_VERSION macro since clang works hard to be gcc compatible. check-in: 810d2932 user: drh tags: trunk
