155785 - crash when processing many "server wants to load image" dialogues

Status: RESOLVED INVALID

(Core :: Graphics: Image Blocking, defect)

Description

[Adam Shaun Nealis]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; FreeBSD i386; en-US; rv:1.0.0) Gecko/20020617
BuildID:    Mozilla 1.0

While loading images from a new site that (maybe) contains links to images on
other new sites, processing the "foo.com wants to load an image" dialogue boxes
can cause mozilla to crash.


Reproducible: Sometimes
Steps to Reproduce:
1. In Edit/Preferences.../Privacy & Security/images set Accept all images, and
check "Ask me before downloading an image".
2. Load a page which is a new host, with maybe links to images on other new hosts.
3. While saying Yes or No to the many dialogue boxes that appear, 

Actual Results:  After processing one or two dialogue boxes, mozilla immediately
dies. The only diagnostic I have found is on my text console (caught by xalf):

Bus error
Jul  3 14:10:41 adam /kernel: pid 84417 (mozilla-bin), uid 1001: exited on signal 10

I can't find core dumps.

Expected Results:  Mozilla should have continued to function.

This has happened in mozilla versions from 0.9.X -> 1.0.0, under FreeBSD
4.4-STABLE and 4.6-STABLE, using XFree86 4.0.1 and XFree86 4.2.0 with GNOME
1.4.0 + either enlightenment 0.16.5 or sawfish-gnome 1.1.

I dunno how to make mozilla produce better debugging information, but am
prepared to help out if I can be given clear instructions!

Component was wrong - changed to Image Blocking

you won't get any core dumps because of bug 148453

the "Ask me before downloading an image" was disabled in 1.0 because of the
crash you are experiencing.  see bug 146513 and bug 110112

where did you get a build with that pref enabled?

ACK.

So my workaround is to either allow all images, no question,
or deny all images, no question?

Beware FreeBSD users using ports: It was installed by me straight
out of the FreeBSD ports tree. The build comes from 

mozilla-source-1.0.tar.bz2

but is patched with these
ftp://ftp.freebsd.org/pub/FreeBSD/branches/-current/ports/www/mozilla/files/

and built with (at least) these ./configure options:

--disable-auto-deps             \
                --enable-chrome-format=jar      \
                --disable-cpp-exceptions        \

                --enable-crypto                 \

                --with-system-png=${LOCALBASE}  \
                --with-pthreads

Should the ports maintainer be contacted?

(or accept only images from originating site, no question)
as long as you do "no question", you should be fine.

you can also accept images and then block from servers when you visit them.

do you mean this one?

I didn't see anything there that should have re-enabled the pref.

moz has been behaving itself since I switched on "accept
all". I'm happy with that.

Then it's a mystery. Unless you want to take this further I'm
happy if you want to close the bug.

ok. resolving as INVALID (it's not Mozilla's fault demons infested your source :))
