471472 - Files not closed (handles still open) after forms submitted and tabs closed

Status: RESOLVED DUPLICATE of bug 183689

(Firefox :: General, defect)

Description

[Marius Hudea]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5

Part of my work involves opening 10-13 websites and uploading on each website a .torrent file along with description, a .nfo file and one image.

Not all the time, but quite often, after each form is submitted and tabs are closed, the files remained opened by Firefox and can not be deleted.

For example, using SysInternal Process Explorer, I can see that Firefox has about 24 open handles for files, including some opened more than 20 hours ago, the previous day. You can see the handles in the picture (blocked some of the file names because it's erotic content and not relevant to this discussion)

While writing this, the last handle on the list was closed, about 10-15 minutes after the forms were submitted and tabs closed.



Reproducible: Sometimes

Steps to Reproduce:
1. Start Firefox
2. Submit form with at least two file inputs.
3. Watch how file handles remain opened.
Actual Results:  
Some file handles remain opened

Expected Results:  
File handles should be closed after a short time, if not as soon as the form is submitted to server.

Note that usually I open several tabs, between 10 and 15, and submit forms one after another, quite rapidly. 

I'm now thinking that it could be some race condition or something like that happening, because some websites respond slower and the upload takes more time. Mayeb Firefox doesn't close the handle because the file is in use by other tab?

I suppose it could happen that the files are opened several times and closed only once or fewer times by Firefox but I'm not one to guess.
