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: 45797feefe user: drh tags: trunk)
21:36
Remove an redundant function call from the date/time function implementation. (check-in: 4a04c48a31 user: drh tags: trunk)
20:43
Fix another corner-case for the 'start of ...' modifier in the date/time functions. Related to ticket [6097cb92745327a1]. (check-in: 8831f4393d user: drh tags: trunk)
20:02
Fix a case introduced by [4cd2a967] where a corrupt database could cause a buffer overwrite. (check-in: 5d0455fece user: dan tags: trunk)
16:51
Before beginning an incremental checkpoint in RBU, sync the directory containing the target database file. This ensures that the new directory entry created by renaming the *-oal file to *-wal is synced to disk. (check-in: 915a9a2878 user: dan tags: trunk)

21:29
Merge the latest updates from trunk. (check-in: 55c00f716d user: drh tags: memjournal-exp)
21:22
Reduce the amount of heap memory required to store many schemas by storing the column datatype appended to the column name (with a \000 separator), rather than in separate memory allocation. (check-in: 16fbf2e19c user: drh tags: trunk)
20:42
Allow the left-hand side of IN operators on virtual tables to have the aConstraintUsage[].omit flag clear. (check-in: 3eb7434274 user: drh tags: trunk)
17:54
Merge 3.11.1 changes into trunk. (check-in: 7abc2dd953 user: drh tags: trunk)
16:17
Version 3.11.1 (Leaf check-in: f047920ce1 user: drh tags: release, branch-3.11, version-3.11.1)
15:16
Increase the default upper bound on scope to 30. (check-in: b1258814f6 user: drh tags: branch-3.11)

Clean up #ifdef logic dealing with VxWorks in os_unix.c. On VxWorks, automatically use posix advisory locking if it is available or fall back to named semaphore locking if not. (check-in: ac8c7ca3db user: drh tags: trunk)
19:56
Fix compiler warnings when compiling under VxWorks 7. (check-in: 55c21521a6 user: drh tags: trunk)
16:58
Enhance SQLITE_ALLOW_URI_AUTHORITITY to elide //localhost/ and to deal with dodgy URIs that contain too many "/" characters. (check-in: 39b566a2d0 user: drh tags: trunk)
14:00
Fix over-length source code lines in the main.c source file. (check-in: debba6f161 user: drh tags: trunk)

Refactor the sqlite3VdbeRecordCompare() routine used to compare btree records. Create a couple of fast-track routines to handle the common cases of a string with BINARY collation or integer values as the left-most column. This gives a significant performance boost in common use. Oops: This build does not work on the Beaglebone where "char" defaults to unsigned. (check-in: aec5473a75 user: drh tags: broken-on-arm)
21:46
Fix a couple of harmless compiler warnings. (Closed-Leaf check-in: fcf480cc63 user: drh tags: experimental)
20:48
Avoid a buffer overread in vdbeCompareRecordInt() that might occur if the database is corrupt. (check-in: 7c0b4381f0 user: dan tags: experimental)
19:29
Fix a typo in a comment. No changes to code. (check-in: 1f4991ab16 user: drh tags: experimental)
18:25
Fix compiler warnings. (check-in: ba8993727e user: drh tags: experimental)
17:48
Merge latest trunk changes. (check-in: 1d60356462 user: dan tags: experimental)
17:36
Change an OP_SCopy into an OP_Copy in a case where the destination might be used after the source has changed. (check-in: c0fa0c0e2d user: drh tags: trunk)
16:48
Change the "explain_i" tcl test command so that xterm color codes are only added if the output is actually a terminal. (check-in: 559835e54e user: dan tags: trunk)
15:13
Fix a harmless compiler warning. (check-in: d7f6837e69 user: drh tags: experimental)
14:45
Merge latest trunk changes. (check-in: e00ed717fb user: dan tags: experimental)
14:20
Fix a segfault that can occur following an OOM error. (check-in: 7fdd378d54 user: dan tags: trunk)
00:12
Change the MEM_Dyn flag so that it means that Mem.xDel exists and must be used to free the string or blob. Add tighter invariant checks on Mem. (check-in: e3f6c61e03 user: drh tags: trunk)

Add the test_fs.c test module to Makefile.in. Adjust the success criteria on index5-1.3 so that it works under auto_vacuum configurations. (check-in: b457c8870a user: drh tags: trunk)

Additional documentation and tests making it clear that whenever sqlite3_prepare() fails it sets *ppStmt to NULL. (CVS 4818) (check-in: 39769f00c5 user: drh tags: trunk)
