2018-04-23
19:30
Disable the OR optimization based on expressions in the ON clause of a LEFT JOIN. This is a temporary measure until we can devise a better fix. (Closed-Leaf check-in: 4df5ea93 user: drh tags: begin-concurrent-pnu-tempfix)
2018-03-22
20:35
Add APIs to the sessions module for "rebasing" changesets. (check-in: 509506c7 user: dan tags: trunk)
20:11
Remove some unused code from sqlite3rebaser_rebase(). (Closed-Leaf check-in: 07cc955e user: dan tags: sessions-rebase)
19:52
Fix another problem with rebasing updates against multiple remote changes. (check-in: c8e7b5a0 user: dan tags: sessions-rebase)
17:13
Fix an RBU problem causing errors when updating tables with default collation sequences that require quoting (e.g. COLLATE "ICU_root-u-kn-on"). (check-in: eb4f452e user: dan tags: trunk)
17:02
Fix a test script problem causing rbuvacuum.test to fail when run along with other tests. (check-in: 901cb3b6 user: dan tags: trunk)
14:07
Add tests to ensure that patchsets are handled correctly by the session rebase APIs. (check-in: 0e45baae user: dan tags: sessions-rebase)
12:00
Add the left join strength reduction optimization. Enhance the push-down optimization so that it works with many LEFT JOINs. (check-in: dd568c27 user: drh tags: trunk)
11:28
Add the --valid-sql option to the optfuzz test program. (check-in: a8dfeec7 user: drh tags: trunk)
11:15
Remove some unused code from the sessions module. (check-in: a09518ab user: dan tags: sessions-rebase)
2018-03-21
20:21
Get the optfuzz program working. (check-in: 21346bbc user: drh tags: trunk)
20:13
Merge latest trunk changes into this branch. (check-in: d00b71ec user: dan tags: sessions-rebase)
19:25
Add the optfuzz.c program for verifying the query planner using a fuzzer. This is an initial code check-in. (check-in: 3fb21251 user: drh tags: trunk)
01:59
Relax LEFT-JOIN restrictions on the push-down optimization. (Closed-Leaf check-in: b5d3dd8c user: drh tags: join-strength-reduction)
2018-03-20
22:52
Do a more thorough job of cleaning traces of the strength-reduced LEFT JOIN. (check-in: 08833dda user: drh tags: join-strength-reduction)
21:16
If terms of the WHERE clause require that the right table in a LEFT JOIN not be a null row, then simplify the LEFT JOIN into an ordinary JOIN. (check-in: 5b7abecc user: drh tags: join-strength-reduction)
19:02
Fix incorrect testcase labels on two cases in join5.test. No changes to code. (check-in: 4661ac81 user: drh tags: trunk)
18:08
Improvements to the HAVING-to-WHERE optimization. The code uses less space and less CPU, and there is now ".selecttrace" output. (check-in: 5ad668d4 user: drh tags: trunk)
16:56
For 'zipfile', detect attempts to cause a duplicate entry via UPDATE. Also, fix handling of 'UPDATE OR REPLACE' statements run on zipfile virtual tables. Win32 portability fixes to the 'fileio' extension. Miscellaneous test fixes. (check-in: b36caeca user: mistachkin tags: trunk)
14:00
Merge all recent trunk enchancements, and especially the autoincrement write reduction fix. (check-in: 25790049 user: drh tags: begin-concurrent-pnu)
13:54
Remove debugging puts from concurrrent3.test. (check-in: 13b49756 user: drh tags: begin-concurrent)
13:52
Merge all recent enhancements from trunk. (check-in: b0c2f760 user: drh tags: begin-concurrent)
13:44
Avoid unnecessary write to the sqlite_sequence table when an insert is done into an autoincrement table with an application-specified rowid that is less than the maximum. (check-in: ec7addc8 user: drh tags: trunk)
13:26
Add the ability to disable the push-down optimization using the 0x1000 bit of SQLITE_TESTCTRL_OPTIMIZATIONS. Also some documentation fixes and an enhancement to ".eqp full" in the CLI. (check-in: ae34edb7 user: drh tags: trunk)
13:00
Remove a debugging statement accidently left in check-in [eddc35f3057e59fd] (Closed-Leaf check-in: 85a31557 user: drh tags: push-down-disable)
12:04
In the CLI, avoid extra .selecttrace and .wheretrace output when in ".eqp full" mode. (check-in: 427bbf31 user: drh tags: push-down-disable)
