task xml file corruption

Reported by Darren Hart | November 21st, 2008 @ 07:49 PM | in BrainDump 1.0

Some yet-unknown circumstance will cause braindump to fail to complete the write-out of the task xml files. The application will fail to load with a SAX error. Manually adding:

to the end of each corrupt file will allow the application to start up again.

    Commit f02fe717b7d16f83a94b40251f886a2e21e33f0a adds some debug() statements and also ensures every file is closed after write. Perhaps we were losing some data. We'll run like this for a while, should it not be reproducible with the additional fd.close() calls, we'll close this ticket out.
