16 check-ins using file src/vdbe.c version f2706d55

2016-05-25
18:53
Add the libvers.c tool in the tool/ subdirectory. (check-in: 2a41f098 user: drh tags: trunk)
2016-05-24
18:55
Enhance Lemon and the parser template so that it can once again build parsers that have no unreachable branches. (check-in: 41fd46e2 user: drh tags: trunk)
18:50
Minor change to the walcrash4.test module so that it works when SQLITE_DEFAULT_WAL_SYNCHRONOUS is set to something other than 2. (check-in: 61e239bc user: drh tags: trunk)
16:20
Fix an obscure problem with transactions written in "PRAGMA synchronous=full" mode on systems that do not support POWERSAFE_OVERWRITE causing an xSync() call to be omitted if the last frame written by a transaction is aligned to a sector boundary. This means that if a power failure or OS crash occurs very soon after such a transaction is committed, it may be lost following system recovery. (check-in: 37de3eab user: dan tags: trunk)
00:40
Improvements to the initialization of the push-down automoton for the Lemon-generated parser. Smaller and faster. (check-in: 3b28b68e user: drh tags: trunk)
2016-05-23
21:56
Use a pointer to the top of the stack rather than an index into the stack in the Lemon-generated parser template, for about 6.6% parser performance gain. (check-in: 3c2a7705 user: drh tags: trunk)
19:02
Avoid a minor error message when running RTREE without an sqlite_stat1 table. (check-in: 276e92f5 user: drh tags: trunk)
18:27
Fix the rtreeG.test test case. (Closed-Leaf check-in: 9589e937 user: drh tags: tree-stat1-fix)
18:12
Fix RTREE so that it does not run queries against the sqlite_stat1 if that table does not exist. (check-in: 48526a2f user: drh tags: tree-stat1-fix)
18:06
Remove an extra "finish_test" from the end of rtreeC.test. (check-in: bfbb6dd8 user: drh tags: tree-stat1-fix)
16:16
Improve the error messages generated by the rtree module when a constraint fails. (check-in: 3ad2531e user: dan tags: trunk)
16:15
Lemon enhancement: avoid unnecessary reduce actions that convert one non-terminal into another but have no side effects. (check-in: a86e782a user: drh tags: trunk)
14:24
Fix comment typos and improve clarity of presention in Lemon. The output should be identical. (check-in: b91a5b82 user: drh tags: trunk)
00:10
Update the configure script with additional hints on the location of tclConfig.sh, hints needed by the latest versions of Xcode. (check-in: 90411a28 user: drh tags: trunk)
2016-05-21
23:25
More tweaks to improve the performance of the insert logic, slightly. (check-in: dec13075 user: drh tags: trunk)
20:03
Simplify the sqlite3BtreeInsert() interface by gathering the five arguments describing the content to be inserted into the new BtreePayload structure, and thus reducing the number of parameters from eight to four. (check-in: 55f348cd user: drh tags: trunk)
