| * | tdb: Reimplementation of Metze's "lib/tdb: if we know pwrite and pread are ↵ | Rusty Russell | 2009-08-14 | 1 | -5/+10 |
| | | | | | | | | | | | | | | | | | | | | | | | | thread/fork safe tdb_reopen_all() should be a noop". This version just wraps the reopen code, so we still re-grab the lock and do the normal sanity checks. The reason we do this at all is to avoid global fd limits, see: http://forums.fedoraforum.org/showthread.php?t=210393 Note also that this whole reopen concept is fundamentally racy: if the parent goes away before the child calls tdb_reopen_all, the database can be left without an active lock and another TDB_CLEAR_IF_FIRST opener will clear it. A fork_with_tdbs() wrapper could use a pipe to solve this, but it's hardly elegant (what if there are other independent things which have similar needs?).

| | | | | | | | | | | | | | tdb_reopen_all() should be a noop" This reverts commit e17df483fbedb81aededdef5fbb6ae1d034bc2dd. tdb_reopen_all also restores the active lock, required for TDB_CLEAR_IF_FIRST.

| | | | | | | | | | | should be a noop The reason for tdb_reopen_all() is that the seek pointer on fds are shared between parent and child. metze | ||||
