281671 - Disk full causes re-download of messages left on pop server.

Status: RESOLVED DUPLICATE of bug 239455

(MailNews Core :: Networking: POP, defect)

Description

[Ric Molen]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041113 Firefox/1.0
Build Identifier: Thunderbird 0.9 20041109

preference "Leave messages on server" is yes. Opened Thunderbird not realizing
disk was full. Opened fine and displayed two messages indicating disk may be
full. Closed Thunderbird.  Removed unrelated files to get 2.2GB disk space. 
Re-opened Thunderbird which then re-downloaded 200+ messages left on server.  It
seems that T-bird 'forgot' that these messages were already downloaded, perhaps
by corrupting a file containing that info before realizing the disk was full.

Reproducible: Didn't try

Steps to Reproduce:
1. Set "Leave messages on server"
2. Put some messages on server, start Thunderbird so it gets these messages.
3. Fill disk (actually /home partition) entirely then start Thunderbird
4. Close Thunderbird
5. Make room on disk then start Thunderbird
6. Thunderbird re-downloads messages

Actual Results:  
Thunderbird downloaded messages from server that were already downloaded

Expected Results:  
Thunderbird should have remembered that those messages were already downloaded,
and thus not downloaded them a second time.

I have not tried to reproduce this problem, but it seems pretty straightforward.

I fill up the partition my profile is on all the time, and see this every time
(I only keep mail on pop for 1 day, though). There's a bunch of different "this
and that lost on disk full" bugs already, but I don't see one about this
specifically yet.

Would this be solved by just using a temporary file for writing popstate.dat and
then moving it to the destination if successful? That sounds like it should at
least preserve the valid information from before.

duplicate of bug 239455?
(which may also be a duplicate of one of the many other "pop bugs")

except for the specification of "Leave messages on server" (which I don't think
is relevant) I don't see how this is different from any of the other reports.
