332883 - Thunderbird freezes while searching in a folder with lots of messages ( search bar )

Status: RESOLVED FIXED

(Thunderbird :: Mail Window Front End, defect)

Description

[César]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; es-ES; rv:1.8.0.1) Gecko/20060313 Debian/1.5.dfsg+1.5.0.1-4 Firefox/1.5.0.1
Build Identifier: version 1.5 (20051201) http://www.mozilla.com/products/download.html?product=thunderbird-1.5&os=linux&lang=en-US

I have a folder containing lots of emails (around 4000 messages).
If I try to search in this folder using the search bar, Thunderbird freezes (it is not responsive anymore to any click/keypress, and it doesn't redraw if I change the size of the window or switch to another window).

If I search using the tool Edit => Find => Search Messages, it works fine (it finds the messages very fast, indeed).

It happens with Mozilla's Thunderbird version (version 1.5 20051201) and also with Debian's Thunderbird version (1.5-4).


Reproducible: Always

Steps to Reproduce:
1. Click on a folder with tons of messages
2. Search some text using the search bar

Actual Results:  
Thunderbird freezes. It is not responsive anymore, and top shows 99% of CPU usage.

First, it seems this bug has to do with Bug 331014.

Second, I can confirm it in Thunderbird 1.5.0.5 (20060725), on SuSE 10. I tried searching two news threads (on news.gmane.org):
gmane.comp.lang.haskell.general (12309 messages)
gmane.comp.lang.haskell.cafe (14453 messages)
The first one always searches fine (through the search bar), the second one always hangs. Using the search tool as described by previous poster works for both folders.

One thing I noticed is that the thread that hangs has some messages in it, that have unreadable subjects - all small question marks in black ovals. One such message on haskell.cafe is on 04/20/2002 09:07AM.

Cheers,

I just realised that the other folders also have unreadable messages, so this shouldn't be a problem.

ignore it when a message says it's a child of itself

N.B., the first patch is required for people who already have corrupt db's...

fix root cause of problem
[Checkin: Comment 8 (*2) & 11]

this patch prevents the corruption from happening; the previous patch handles the already corrupt threading. The other code that iterates over threads already handle this case. We'll let this bake on the trunk and branch, but requesting approval while I remember...

I have not been able to reproduce this, so if anyone seeing this problem can test a recent nightly build (http://ftp.mozilla.org/pub/mozilla.org/thunderbird/nightly/) and verify that this is fixed, that will be great!  Please update the fixed1.8.x keyword(s) with verified1.8.x.  Thanks!

gmane.comp.lang.haskell.cafe searches fine in Thunderbird 1.5.0.7 (20061023). I don't have permission to change bug status however.

If someone (the reporter or another person who has seen the bug) can please verify the fix from a candidate build in this directory, that would be great - ftp://ftp.mozilla.org/pub/mozilla.org/thunderbird/nightly/1.5.0.8-candidates/rc1/

Tried several types of searches in folders with many messages >5000, threaded and unthreaded, and I don't see Tbird 2 freezing.
