92 check-ins using file src/main.c version 1f54ee71

2018-09-24
20:50
Fix missing space in 'configure.ac' reported on the mailing list. (check-in: 4407e15a user: drh tags: branch-3.25)
20:48
Add the "PRAGMA legacy_alter_table=ON" command to enable the pre-3.25.0 behavior of ALTER TABLE that does not modify the bodies of triggers or views or the WHERE clause of a partial index. Enable the legacy behavior by default when running the xRename method of virtual tables. (check-in: 31dc8b19 user: drh tags: branch-3.25)
19:41
Allow a writable virtual table to have a schema with an INTEGER PRIMARY KEY and WITHOUT ROWID. This fixes ticket [f25d5ceebe1d710ff61a571e395356869d8272ef]. Test case in TH3. (check-in: 3139af99 user: drh tags: branch-3.25)

17:00
Enhance tester.tcl so that when "--malloctrace=1" is specified, the test generates self-contained Tcl scripts that present GUIs instead of *.sql files that require a separate program to interpret. (check-in: de2e3cbd user: dan tags: trunk)
16:06
Minor improvements to the permutations.test script. Most notably, a command like "permutations.test alter%" now runs all test scripts with names that match the LIKE pattern "alter%". Or, say, "permutations wal alter%" to run all alter% tests in wal mode. (check-in: 3e1a2f66 user: dan tags: trunk)
2018-09-17
