Fix a harmless compiler warning in the sessions test harness. (check-in: d389e20ab0 user: drh tags: sessions)
14:53
Enhance the test harness for the sessions interface so that it does not use SQLite operations that can encounter an OOM error in places where it is unable to report an OOM error back up to the test script. (check-in: bc0e661033 user: drh tags: sessions)

Add tests to join.test to verify that it is not possible to use more than 64 tables in a join. (check-in: ef1a998625 user: dan tags: trunk)
15:52
Count the number of elements in a SrcList object using an "int" rather than a "u8", to avoid overflows and to work around an issue in the C compiler on AIX. (check-in: eee2a13f2c user: drh tags: trunk)
15:04

14:40
When converting a result type from TEXT to BLOB using the sqlite3_value_blob() interface, continue to report SQLITE_TEXT as the true type from sqlite3_value_text() as long as that text is still valid. The maintains legacy behavior from before the noMemType change. (check-in: 1d134ba2ed user: drh tags: trunk)
12:47
Separate the column NULL value constant into a separate routine for greater commonality with the sessions branch. (check-in: 12cbebb997 user: drh tags: trunk)

Fix harmless compiler warning. (check-in: 8d18a803bd user: mistachkin tags: trunk)
04:12
Refactor the sqlite3VdbeRecordCompare() routine used to compare btree records. Create fast-track special case routines to handle the common cases more quickly. This gives a significant performance boost. (check-in: 3325ad5bdc user: drh tags: trunk)
04:04
Fix more instances of assuming 'char' is signed. And, make sure to never shift a signed integer. (Closed-Leaf check-in: f10130ede4 user: drh tags: broken-on-arm)

Do not assume that 'char' is signed. Make it explicit. (check-in: 979da752e6 user: drh tags: broken-on-arm)
2014-03-03
21:59
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 typo in a comment. No changes to code. (check-in: 1f4991ab16 user: drh tags: experimental)
