10 check-ins using file src/sqlite.h.in version 592057b6

2013-12-13
20:45
Performance optimizations in the pager_write() routine of pager.c. (check-in: bc5febef user: drh tags: trunk)
19:48
Reduce the number of calls to the subjRequiresPage() routine inside of pager. (check-in: e50ff39a user: drh tags: trunk)
19:35
Create and use a new pager interface sqlite3PagerUnrefNotNull() that works just like sqlite3PagerUnref() but guarantees that its argument is not a NULL pointer. (check-in: e00f37e2 user: drh tags: trunk)
18:50
Enhance the pcache1PinPage() routine so that it called much less often and runs much faster in the cases when it is actually called. (check-in: a845779c user: drh tags: trunk)
16:42
Avoid unnecessary calls to sqlite3_free() from within sqlite3VXPrintf(). (check-in: e2a8b280 user: drh tags: trunk)
16:23
Simplication and optimization of error message handling. (check-in: 9d347f54 user: drh tags: trunk)
2013-12-11
15:47
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)
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)

17:34
Use SQLITE_FCNTL_SYNC instead of SQLITE_FCNTL_SYNC_OMITTED. Add documentation in for FCNTL_SYNC and FCNTL_COMMIT_PHASETWO. (check-in: 46231af9 user: dan tags: zipvfs-multifile-commit)
