13:51
On the first connection to a WAL-mode database that was not cleanly shut down and contains a left-over -shm file, truncate the -shm file to 3 bytes instead of to 0 bytes. Avoiding a truncation to 0 means that system monitoring tools can better detect if a process illegitimately tries to truncate a -shm file. Such a rogue process might think it is being helpful by cleaning up old files, but there is a race condition that can cause damage to the database. check-in: 90cf32cd user: drh tags: trunk

20:15
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: 7edd26ed user: drh tags: trunk
19:02
Combine the Expr.pTab and Expr.pWin fields into a union named "y". Add a new EP_WinFunc property that is only true if Expr.y.pWin is a valid pointer. This reduces the size of the Expr object by 8 bytes, reduces the overall amount of code, and shaves over 1 million cycles off of the speed test. check-in: ad130bb8 user: drh tags: trunk
17:21
By default, make all "ALTER TABLE RENAME" statements executed within a virtual table xRename() method exhibit the legacy behaviour. Closed-Leaf check-in: 71947337 user: dan tags: legacy-alter-table

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
20:47
