58535 - image cache getting mixed around

Status: RESOLVED FIXED

(Core :: Networking: Cache, defect, P3)

Description

[Bob McElrath]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux 2.4.0-test9 i686; en-US; m18) Gecko/20001027
BuildID:    2000102708

Items in the image cache get mixed around.  Images from one web site (known to
be in the cache) is showing up on another site.  Images from the same web page
appear in the wrong place.

Reproducible: Didn't try
Steps to Reproduce:
Browse for a while.  Wait for cache to have lots of entries.  Mozilla has been
running for a day, ~50 pageviews.  (Hey, it's been running for a day!  It's
getting better!)

Actual Results:  Cached images mixed up.

Expected Results:  Cached images not mixed up.

Reloading the page several times, and going to different pages and coming back
appears to have no effect.  That is, the same images are mapped via the cache to
the same other (wrong) images, even after loading several other pages.  Thus,
the cache corruption rate is probably low (memory leak?).  Server returns [304
not modified] every time for these images.  Images that get mixed up are of
different dimensions (sizes) and mozilla rescales them where they appear.
Forced reload (shift-reload) does not restore correct images.  (does
shift-reload work under mozilla as it did under netscape?)  Forced reload causes
mozilla to reload same image in an endless loop (image is
http://images.slashdot.org/greendot.gif, 53 bytes, observed by looking at proxy
logs)  Debug->Flush Memory does not fix the problem.

I regularly see exactly what you're describing with daily linux builds,
after extended periods of browsing. In my case, the images come from
the page I use as my home page; that page has several dozens small images.
Marking confirmed.

Same here, on Linux (all recent CVS builds). The
http://images.slashdot.org/greendot.gif image gets loaded over and over again,
until I press ESC. The actual image does not appear on screen. It made my
junkbuster logfile grow to about 100 MB...

Frank:

There was a cache corruption problem back in October.
If you completely delete your cache, do you see the
problem?

I attached redused testcase from slashdot page. When you load that file
and hit realod, green dot starts to blink, gif is realoded from net over
and over again.

I am still seeing this bug (image cache mixup) with nighlies since 12/26/2000
(when this was marked as FIXED).  Just how, and when was it fixed?  I'll post
another comment if I see it with 0.8 (as soon as I get it to not segfault, see
bug 69058.
