* Optimize queries of the form "SELECT count(*) FROM <tbl>" by adding a ↵danielk19772009-02-24
| | | | | sqlite3BtreeCount() interface to the btree layer. (CVS 6316) FossilOrigin-Name: d4aa6593183224b6868a322511511c0bbf63b598
* Scan an index instead of a table for "SELECT count(*) FROM <tbl>" queries. ↵danielk19772009-02-23
| | | | | Because an index is usually smaller than a table on disk, this saves some IO. (CVS 6315) FossilOrigin-Name: 294ba6f743c9132dce0e73da480bd3c2071e7239

* Move the text of C-API requirements out of the sqlite.h.in source file anddrh2009-02-18

* Add tests to double-check that nothing within SQLite ever tries to allocatedrh2009-02-17
| | | | | | | amounts of memory that are close to the maximum signed integer, leading to an integer overflow within malloc(). This is not currently a problem. The extra tests just insure it never becomes a problem. (CVS 6298) FossilOrigin-Name: f6ba7bb9152cffc9f67dfa7de12e36a3244b7e03

* Allow sqlite3_shutdown() to be called by a process before ↵danielk19772009-02-17
| | | | | sqlite3_initialize() is. Prior to this commit such a call could segfault. (CVS 6296) FossilOrigin-Name: 79431c58d964d6057c7f42f7c1df74f3df4493eb

* Fix some edge cases with backing up databases that are exactly PENDING_BYTE ↵danielk19772009-02-12

* Fix a case where during a rollback triggered by an IO or malloc error an ↵danielk19772009-02-12
| | | | | unjournalled region of the database could be written to (with it's original data). This was causing an assert in test_journal.c to fail. Add a test case in ioerr2.test to trigger this case. (CVS 6286) FossilOrigin-Name: 315a6692f9a03a470871cce4f74567683546f343

* Fix the crashtest infrastructure so that it doesn't trigger the "don't write ↵danielk19772009-02-11

* Modify the test_journal.c code to (1) account for the backup code writing to ↵danielk19772009-02-11
| | | | | parts of the pending-byte page when changing a databases page-size, and (2) to avoid reading from the pending-byte page and triggering the assert in os_unix.c. Changes to test code only. (CVS 6280) FossilOrigin-Name: 4879621658c2c785ab7b12dbae780901496d3a78
* In test_mutex.c, zero the global structure staticly instead of in ↵danielk19772009-02-11
| | | | | Sqlitetest_mutex_Init(). This is because Sqlitetest_mutex_Init() is now called by each thread during thread tests ((6193)). Test code changes only. (CVS 6279) FossilOrigin-Name: 8b318b9385d0542ca56750b901c0c6b7d05ca634
* For the "onefile" demo, pass SQLITE_OPEN_TEMP_DB instead of MAIN_DB to the ↵danielk19772009-02-10
| | | | | OS layer when opening the single file. This is to work around the assert() in os_unix.c that tests that the locking region is not written to. (CVS 6278) FossilOrigin-Name: 2da076a2c1663e916dc50e5e1679be216922dfc5
* Prevent code in test6.c from reading the 512 byte locking region (the ↵danielk19772009-02-10
| | | | | PENDING_BYTE page) of a database file. Doing so triggers an assert failure in os_unix.c. (CVS 6276) FossilOrigin-Name: 2a6a43169220fab5a15a786e2a464b90cb893179

* Changes to the backup API: (1) if a negative number is passed as the second ↵danielk19772009-02-06
| | | | | argument to backup_step(), this is interpreted as "copy all remaining pages" and (2) if backup_finish() is called after backup_step() fails with a BUSY or LOCKED error, then this error is also returned by backup_finish() (same handling as for other errors encountered by backup_step()). (CVS 6266) FossilOrigin-Name: 9b8c8b18cf6b7d44d5fd64760537bc030097756b
