230494 - Offline folder processing does not sense disk full, IMAP mail reading fails

Status: NEW

(SeaMonkey :: MailNews: Backend, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5) Gecko/20031007

I have "offline folder" set for by IMAP inbox. The offline file kept
increasing (see bug #222938). Eventually the disk partition filled
up completely. The UI kept indicating that mail items exist offline
(greyed envelope icon), when they were actually not written anymore.
These mail items could not be read anymore (blank page when double-
clicked). Only remedy is to completely delete the offline folder file.

Reproducible: Always

Steps to Reproduce:
1. Mark an IMAP folder for offline use.
2. Have it increase to the point where the disk fills up.
3. "download to offline" a few more mail items. No error message.
4. Try to read one of the mail items from 3 above.

Actual Results:  
UI indicates the item is available offline. Trying to read it
(even when online) displays a blank page.

Expected Results:  
An error message when not being able to write to offline folder;
UI not indicating the item is offline; opening the item when online
reads it from the server-side IMAP folder.

I have seen this problem in another way: I installed Mozilla and synchronized my
1.6 GB of email, not noticing that I only had about 500MB free.  Mozilla went
ahead and did the synchronization, but then got really messed up.  It actually
appeared that the index to mail messages got screwed up somehow, so that I would
click on messages and get completely blank results.  This problem persisted both
online and offline.  It was only by deleting the account and restarting that I
fixed this (although I didn't try deleting individual folders).

I see the problem when downloading messages for offline use with IMAP- _AND_ news-messages.
