Actually, I'll need to update FooBar/current and FooBar/edit-log and data/edit-log and data/event-log too, in addition to the FooBar/revisions/00000006 file... I'm definitely uncertain as to how to do this atomically such that there is no possible conflict with the online wikiwiki instance. Presumably, the consequences for messing up the logs would be far less than if "current" and/or "00000006" file were updated wrongly. So, maybe, 1) Detect what the latest revision is, say, 23 2) Read that latest revsion, (say, 23) 3) Process it to generate desired revision, say, 24, in /tmp 4) mv the entry from tmp to revisions _and_ update current 5) If that fails, then someone else updated it, try again from (1) 6) Append to the 2 edit-log files and update the event-log My concern is how to do (4) atomically. ------------------------------------------------------------------------------ Check out the new SourceForge.net Marketplace.
