256183 - Extremly slow saving of attachements if one message contains more than about 20 attachements

Status: RESOLVED EXPIRED

(MailNews Core :: Attachments, defect)

Description

[David Kredba]

User-Agent:       Mozilla/5.0 (compatible; Konqueror/3.2; Linux) (KHTML, like Gecko)
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.2) Gecko/20040818

My site users sends me messages with spam. They includes spam messages as 
attachements. One message contains about 200 or 500 and more attachemets. 
After I downlod messages to my PC I am saving attachements to folder. 
 
When I use Mozilla with default configuration, it always freezes system, 
because it tried to load all of attached spam messages and display it. 
 
I reconfigure it to not display content of attachements. 
 
Now I am able to save attachements to one folder with "Save all". 
 
One attachement tooks about 10 s (and very more time, if some aplication uses 
much of processor time) to save. Mozilla is consuming 100 % of processor time 
and its window freezes. 
 
My configuration changes, which I am using : 
 
advanced.always_load_images false 
browser.download.progressDnldDialog.keepAlive false 
browser.download.save_converter_index 0 
browser.downloadmanager.behavior 1 
browser.open.filterIndex 0 
browser.toolbars.showbutton.go true 
dom.disable_open_during_load true 
dom.disable_window_flip true 
dom.disable_window_open_feature.status true 
dom.max_script_run_time 2 
dom.popup_maximum 10 
font.language.group x-central-euro 
intl.accept_languages cs, en-us, en 
intl.charset.default ISO-8859-2 
mail.inline_attachments false 
mailnews.message_display.allow.plugins false 
mailnews.message_display.disable_remote_image true 
mailnews.quotingPrefs.version 1 
mailnews.start_page.enabled false 
 
 

Reproducible: Always
Steps to Reproduce:
1. Make message with 200 or more attached spam messages 
2. Right click on attachemnt window, select Save all, choose folder 
3. nad save messages 
 
Actual Results:  
Very slow attachements saving, 100 % processor usage, Mozilla freezes itself, 
no window is usable (mailnews, web browsing etc.) 

Expected Results:  
Save all attachements in very short time (miliseconds ?), without Mozilla 
freezing.

are you saying you think it should save 200+ attachments in milliseconds?  are
you serious?

I wrote it bad.

I think, that time to save one attachement shoul`d be in miliseconds.

[Andrew Schultz]

are you saying 1 attachment took 10 seconds?  did you save just one?  or 200
attachments took 10 seconds x 200 = 2000 seconds (~30 mintues)

It takes abot 30 minutes, average is 10 s per one attachement.
If some message contains about 500+ spam attachements it tooks about 2 hours to
complete.

I am getting this behavior on all of Mozillas from 0.9.x and on misc. linux
distribuitions. On self compiled (Gentoo, LFS) and on binary distributions too
(Fedora, Mandrake).

Only for record.

I found second way, how to do it without Mozilla, until saving attachements will
be fixed.

There is Mbox2eml 1.0.1 © Ulrich Krebs 2002-2003 at
http://people.freenet.de/ukrebs/ .
It is Java powered .jar.

It can read Mozilla mbox archive, select all messages and from each one with
attachements save them to the folder.

12 messages, with 1253 attachements at all, saving took about 1-3 s.

are these pop3 or imap messages? How big is this message with 2-500 attachments?

Comment 7

[David Kredba]

Messages are pop3.

One average report message has about 200 attachements and is about 700-1000KiB.

Above reported Mozilla mbox archive was ~5200000 B.
