- // Test the various ways opening a cookie database can fail in an asynchronous
- // (i.e. after synchronous initialization) manner, and that the database is
- // renamed and recreated under each circumstance. These circumstances are, in no
- // particular order:
- //
- // 1) A write operation failing after the database has been read in.
- // 2) Asynchronous read failure due to a corrupt database.
- // 3) Synchronous read failure due to a corrupt database, when reading:
- // a) a single base domain;
- // b) the entire database.
- // 4) Asynchronous read failure, followed by another failure during INSERT but
- // before the database closes for rebuilding. (The additional error should be
- // ignored.)
- // 5) Asynchronous read failure, followed by an INSERT failure during rebuild.
- // This should result in an abort of the database rebuild; the partially-
- // built database should be moved to 'cookies.sqlite.bak-rebuild'.
