487883 - Image not properly cached, in disk but have 0 bytes (page info or properties)

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Rodrigo]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2a1pre) Gecko/20090410 Minefield/3.6a1pre
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2a1pre) Gecko/20090410 Minefield/3.6a1pre

I clicked on one single image on imagefap and got this.

What I see here:
1. The image is in disk cache but it has 0 bytes.
2. The image is not in memory cache (not shown on pic)
3. It's not a cache collision because cache collisions are marked as (not
cached) in "page info"
4. In page info the image is shown immediately (not from network). I'm guessing
it's from decoded-image cache.
5. After highlighting the url and pressing enter, the image reloaded from
network but was put in disk cache correctly this time around.

Reproducible: Sometimes

Steps to Reproduce:
1.open link: http://imagefap.com/gallery/1594591
2.open some images
3.one of them will show 0 bytes on properties or page info (it's random)

OR

1.install mondofap script to greasemonkey: http://userscripts.org/scripts/show/15603
2.load the link (all images will load in one page)
3.open page info and go to media tab
4.images have 0 bytes
Actual Results:  
Images load correctly but have 0 bytes

Expected Results:  
Images should show the correct size

Could really use reliable (not random) steps to reproduce.

I tested twice now with mondofap steps and it reproduces consistently. Tried even with another gallery.

"
1.install mondofap script to greasemonkey:
http://userscripts.org/scripts/show/15603
2.load the link (all images will load in one page)
3.open page info and go to media tab
4.images have 0 bytes
"

but if you open image one at a time it's is random.

[Boris Zbarsky [:bzbarsky]]

Yeah, ideally I'd like something where the images are opened one at a time.  The greasemonkey thing is nondeterministic, because the loads race against each other.

Comment 5

I forgot to say that I use another script: direct images ++    http://userscripts.org/scripts/show/3923
It replaces the page with the image with the image directly. (When you click some image in the gallery it opens the image, not the page with it.)


I noticed:
-With script, NO images show 0 bytes (one at a time)

-Without script (normal usage), randomly some images have 0 bytes (page info or properties)
Opening one at a time, at least half of them showed the bug (0 bytes).



Another thing, with script sometimes (random) images have the title "getimg.php" instead of the correct name.
Correct link: "http://cdn-nl3.imagefap.com/41a/full/201/2016973760.jpg"
Wrong (getimg) link: "http://77.247.179.161/full/getimg.php?img=146174340.jpg"
Both of them shows only image, not pages.
And both of these links are from the script.



Don't know if that helps but if you need more tests or something just ask ;)
