750100 - Severe data loss while checking mail for UNIX Movemail account

Status: RESOLVED DUPLICATE of bug 748726

(MailNews Core :: Movemail, defect)

Description

[Martijn Dekker]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:12.0) Gecko/20100101 Firefox/12.0
Build ID: 20120420145725

Steps to reproduce:

System: Slackware Linux 13.1 32-bit (GCC 4.4.4, GTK+ 2.18.9). Using Mozilla's official precompiled Thunderbird 12.0 binary from releases.mozilla.org.

Problem: Severe email data loss while checking mail on Movemail (UNIX mail spool) account in Thunderbird 12.0. Only part of the first message is delivered into TB and the rest is lost. This happens even when starting TB in safe mode (using "thunderbird -safe-mode").

Problem is new as of 12.0 and does NOT occur in Thunderbird 11.0.1 and previous. Downgrading to TB 11.0.1 fixes the problem.

Steps to reproduce:
1. Create movemail account (Account Prefs -> Account Actions -> Add Other Account -> Unix Mailspool (Movemail)).
2. Deliver some mail messages in /var/mail/USERNAME
3. Check mail for the movemail account



Actual results:

Only a part of the header of the first message in the mail spool (/var/mail/USER) is delivered to TB, the rest of the message and all other messages waiting in the mail spool are lost. Below is a complete source code sample of such a corrupted message. (Note that it is interrupted in the middle of a header, i.e. MIME-Version.)

Bug 748726?

Martijn, please try again with the TB 12.0.1 update which is expected to be released tomorrow. It contains the fix Magnus was referring to.

Making a backup of your ~/.thunderbird directory would be advisable, and you can also make a folder repair to be safe (right-click on an affected folder, then select Properties and click the "Repair Folder" button to reindex its contents).

The TB 12.0.1 update does seem to have resolved the problem. Thank you, rsx11m. I am marking this a duplicate of the bug referred to by Magnus Melin.

There is now a new, minor issue: every time mail for a UNIX mailspool account is checked, the string "spool path = /var/spool/mail/mdekker" is printed on standard output. This seems like a debugging line that should have been removed. I will file a separate bug about that if no one has already.

I put a patch for removing the printf in bug 748726, which also has a comment mentioning that.
