30 check-ins using file src/where.c version e6a4e713

2013-12-10
16:27
Fix handling of errors returned by the SQLITE_FCNTL_OMIT_SYNCED file-control. check-in: d9a5f44f user: dan tags: zipvfs-multifile-commit
2013-12-09
20:42
Modify the way some internal file-controls are invoked. In order to support multi-file transactions in the zipvfs extension. check-in: 32fb1784 user: dan tags: zipvfs-multifile-commit
12:24
Fix an incorrect test number in the output of the speedtest1.c program. No changes to the test algorithms. check-in: fbfc075a user: drh tags: trunk
03:07
Avoid unnecessary (no-op) calls to sqlite3DbFree() from sqlite3VdbeMemRelease(). check-in: 2d6dd7c2 user: drh tags: trunk
02:32
Use memmove() rather than a home-made copy loop in insertCell() too. check-in: a3d796b1 user: drh tags: trunk
01:58
Use memmove() rather than a home-made copy loop in dropCell() of btree.c, for a size reduction and performance improvement. check-in: 78e17068 user: drh tags: trunk
01:04
Avoid unnecessary no-op calls from getAndInitPage() to btreeInitPage() in the btree.c logic. check-in: 81f5ae13 user: drh tags: trunk
00:47
Use putVarint32() instead of putVarint() for a quantity that can never exceed 2GiB - 1. check-in: 6996fb34 user: drh tags: trunk
2013-12-08
23:33
Another simplification to the OP_MakeRecord opcode, making it slightly faster and very slightly smaller. check-in: f2f5a3ce user: drh tags: trunk
22:59
Avoid unnecessary calls to sqlite3VarintLen() from the OP_MakeRecord opcode. check-in: 7a234fc3 user: drh tags: trunk
19:54
Interchange two conditions in an "if" statment in sqlite3PagerAcquire() for very slight (0.06%) overall performance increase. check-in: fbcc1a3e user: drh tags: trunk
2013-12-07
17:01
Increase the version number to 3.8.3. check-in: 23d00f22 user: drh tags: trunk
16:56
At the start of each journaled write transaction, check to see if the database file has been moved, and if it has refuse to start the transaction, returning an SQLITE_READONLY_DBMOVED error code. Writing to a moved or renamed database is still allowed when journal_mode is OFF or MEMORY. check-in: 369a23e0 user: drh tags: trunk
16:45
Back out the new device capability. The determination of whether or not a file has moved is now done strictly using a file-control. Closed-Leaf check-in: 9c59f5af user: drh tags: detect-moved-db
12:29
Actually look at i-node numbers to determine whether or not the database file has moved. check-in: 2b1884dc user: drh tags: detect-moved-db
2013-12-06
23:25
Performance optimization to the moveToRoot() subroutine in btree.c. check-in: b5842a70 user: drh tags: trunk
22:45
Use memcmp() instead of the BINARY collating function where possible, for a performance boost. check-in: c5a3a1af user: drh tags: trunk
22:44
Remove some commented-out code from sqlite3BtreeMovetoUnpacked() to try to make it more readable. check-in: 2d62d113 user: drh tags: trunk
19:58
Add the SQLITE_READONLY_DBMOVED error code to the sqlite3ErrName() function. check-in: 7789f801 user: mistachkin tags: detect-moved-db
17:23
Only error out on a database file move when attempting to start a write transaction. Assume read transactions are still safe. And make the error SQLITE_READONLY_DBMOVED instead of SQLITE_IOERR_NODB. check-in: 28348f2a user: drh tags: detect-moved-db
15:49
Update to the 3.8.2 release. check-in: e579661a user: drh tags: sessions
15:37
Add code to detect if the database file is moved or deleted out from under SQLite and return an SQLITE_IOERR_NODB. check-in: 8759a8e4 user: drh tags: detect-moved-db
14:53
Version 3.8.2 check-in: 27392118 user: dan tags: trunk, release, version-3.8.2
2013-12-05
17:12
Fix harmless compiler warnings and improve the MSVC makefile. check-in: c6325670 user: drh tags: trunk
16:41
Fix two potential (and apparently harmless) shift overflows discovered by the -fcatch-undefined-behavior option of clang. check-in: e19eead8 user: drh tags: trunk
2013-12-03
23:33
Make use of the CC nmake macro even when cross-compiling (with MSVC). Closed-Leaf check-in: aae7b30e user: mistachkin tags: memTests
22:33
Fix harmless compiler warnings. check-in: a12d214e user: mistachkin tags: memTests
22:32
Add memory subsystem related defines to the compile-time options list. check-in: 52a44146 user: mistachkin tags: memTests
20:51
Merge in trunk changes. check-in: a2914d6b user: drh tags: sessions
19:49
Remove a branch in STAT4 logic that is no longer reachable after the previous change. check-in: eca7d3f1 user: drh tags: trunk
