Add the SQLITE_FCNTL_SYNC and SQLITE_FCNTL_COMMIT_PHASETWO file-controls and have the pager call them at appropriate times. This is needed in order to enable ZIPVFS to do multi-file atomic commits. check-in: 552f94d5 user: drh tags: trunk
14:17
Merge in the latest trunk changes. Closed-Leaf check-in: 9ff4dfe1 user: drh tags: zipvfs-multifile-commit
14:00
Fix a bug in the shell ".import" command: Do not end the field when an escaped double-quote occurs at the end of a CRNL line. check-in: 5e239ecd user: drh tags: trunk
12:02
Remove an unreachable conditional inserted by the previous check-in. check-in: 3e1d55f0 user: drh tags: trunk
11:03
Have the crash-test infrastructure code in test6.c read and write the 512-byte block containing the pending-byte lock as normal. Earlier versions did not access this part of the file in order to avoid triggering an assert in os_unix.c. But the assert() has since been removed. And not reading/writing this part of the file causes problems for multiplexor tests. check-in: fdc3f3fa user: dan tags: zipvfs-multifile-commit
11:00
Fix harmless compiler warnings. check-in: a7e5fcd6 user: drh tags: trunk

Fix harmless compiler warning. check-in: 2525296d user: mistachkin tags: trunk
00:59
Do not run the tool/vdbe-compress.tcl script that generates the vdbeExecUnion object that reduces the size of the sqlite3VdbeExec() stack frame unless the SQLITE_SMALL_STACK compile-time option is specified as on of the OPTS in the makefile. The vdbeExecUnion object gets in the way of C-compiler optimizer and results in slightly slower code. check-in: 4d078147 user: drh tags: trunk
2013-12-10
21:38
Avoid unnecessary calls to sqlite3VdbeSerialType() from within sqlite3VdbeSerialPut(). check-in: 079c04a5 user: drh tags: trunk

2013-12-09
23:17
Simplifications to the OP_MakeRecord opcode and the sqlite3VdbeSerialPut() helper function. check-in: 7277a769 user: drh tags: trunk
21:48
Correct the VFS name as reported by the file control when explicitly using the 'win32-longpath' VFS. check-in: c43b59da user: mistachkin tags: trunk
21:06
Reduce the number of times that OP_Column calls sqlite3VdbeMemMakeWriteable(). check-in: 6b518635 user: drh tags: trunk
20:43
Simplify the sqlite3BtreeKeyFetch() and sqlite3BtreeDataFetch() interfaces to the storage engine. check-in: bf975985 user: drh tags: trunk
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
19:25
Minor performance optimizations in pager.c. check-in: ba9eef5f user: drh tags: trunk
19:03
Performance optimizations for sqlite3VXPrintf(). check-in: 9227ad48 user: drh tags: trunk
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

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

Modify test file conflict2.test so that it works with the "inmemory_journal" permutation. check-in: e4164fd8 user: dan tags: trunk
