124428 - URLNotify not called if plugin is destroyed before NPP_NewStream is called

Status: VERIFIED DUPLICATE of bug 127259

(Core Graveyard :: Plug-ins, defect)

Description

[Ari Berger]

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)
BuildID:    0.9.4 branch

When the plugin is being destroyed, mozilla cleans up its streams by destroying 
them and calling NPP_UrlNotify.
In general, we do receive Notify (unlike bugs 117766 and 117770, because we 
have a NULL target and non-NULL notifyData).
In 2 cases we do NOT get notified.
1) The plugin is destroyed between the time we call GetURLNotify and the time 
you call NPP_NewStream.
2) If we return an error from NPP_NewStream (we cancel the stream during 
NewStream- we decide we don't want it after all.

My assumption is that you call notify on all streams in your array.  Is it 
possible that streams don't get placed into the array until after NPP_NewStream 
returns with no error?



Reproducible: Sometimes
Steps to Reproduce:
1.This is not too easy to reproduce because it is a timing issue- you need to 
close the page with the plugin or hit refresh between the time that the stream 
is requested and the time NewStream is called.  Maybe the sample plugin is the 
easiest way?
If you want to try using our plugin, let me know, and I will try to post 
instructions.  But i don't think that is the easiest way to go.
