94010 - Insufficient free space causes loss of preferences

Status: VERIFIED DUPLICATE of bug 86501

(Core :: Preferences: Backend, defect)

Description

[olga charapaev]

In situation when we are running low on free space
rewriting prefs.js file leads to corruption of the file (it gets truncated) or 
total loss of preferences (we get 0KB prefs.js).
Safer way to do it would be to move prefs.js to backup file before creating new
prefs.js or save the new copy of the prefs to a temporary file in the same 
directory as prefs.js. If creation of the new file is successful, then rid of 
the old file.

Am I wrong or is this a dupe of #86501 where exactly this behaviour and solution
are described? If then I suggest closing this to get rid of an open bug :)

Not that I'm against dupes :) but bug 86501 references multiple files which are
corrupted in this situation. If there were some sort of "safe save" convention
in Mozilla, it could potentially be fixed via one bug. If this exists, I'm not
aware of it. Since the files in question cross multiple components (bookmarks,
for example, is Ben's area) I would leave them both open as the work will
probably have to be done per component.

This will be fixed by the patch in bug 98476.
