288566 - Calling URLSimpleDownload() from plug-in often freezes

Status: RESOLVED EXPIRED

(Core Graveyard :: Embedding: Mac, defect)

Description

[Brian Greenstone]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-us) AppleWebKit/125.5.7 (KHTML, like Gecko) Safari/125.12
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.6) Gecko/20050331 Camino/0.8.3

In my plug-in I will occasionally call URLSimpleDownload() or URLDownload() to download a file from an 
HTTP address.  This works 100% fine with Safari, but with Camino, Netscape, or Firefox it only works 
50% of the time.  What happens is that when URLSimpleDownload() is called it simply locks up.   No 
errors or anything, but it just freezes and I have to force-quit the browser.  

It only freezes like this when the plug-in is streaming a SRC file at the same time.  It's as though 
URLSimpleDownload() is waiting for the other stream to complete before it will work, but since 
URLSimpleDownload() is a blocking call, nothing can happen.

I don't know what could cause URLSimpleDownload() to not work since it should be totally independant 
of the browser, but this is very reproducable, and like I say, it works 100% correctly with Safari.  It's only 
on these other Mozilla browsers that it does this about every other time I try.

Reproducible: Sometimes

Steps to Reproduce:
After a plug-in's NPP_NewStream() function gets called try calling URLSimpleDownload() to download 
some other file from an HTTP (or FILE) URL.  50% of the time you do this URLSimpleDownload() will 
freeze causing the whole browser to freeze.

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce

you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
