* If a malloc fails while allocating a savepoint object at the pager level, do ↵dan2010-06-03
| | | | | not try to roll that savepoint back later on. FossilOrigin-Name: 91cb08ffb6332a142542c012b58aa49206ee5704
* When a lock fails due to an I/O error (not an SQLITE_BUSY) then the checkpointdrh2010-06-02
| | | | | should fail. FossilOrigin-Name: c6eb0a27270df69018576232d8f97c16d63d8f6e
* Fix a problem with rolling back to a savepoint opened before the writer ↵dan2010-06-02
| | | | | decided to wrap the log file. FossilOrigin-Name: 6b4aed6aae7dc9e92807d27375cbe1e83c15841b
* If an error occurs while writing frames to the log to commit a transaction, ↵dan2010-06-02
| | | | | do not mark the pages as clean in the cache. Otherwise, the subsequent rollback does not roll them back (leaving the client to continue with a cache that makes it appear that the transaction was committed - inconsistent with the database on disk).

* Undo one of the "const" markers from the previous check-in because thedrh2010-06-02

* The shared-memory used by WAL on linux now really is shared memory in /dev/shm.drh2010-06-01
| | | | | | On other unix flavors, the file is in a temporary directory rather than in the same directory as the database. FossilOrigin-Name: fc18c4aadb908c3b6f9b6481a2efca6a0daadc64

* Delay the decision to restart the log file until data is actually ready to ↵dan2010-06-01
