783580 - nsIProcess::Run hangs when run with blocking=true on XP

Status: RESOLVED INCOMPLETE

(Firefox :: Extension Compatibility, defect)

Description

[PSC]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.79 Safari/537.1

Steps to reproduce:

When installing an extension on FireFox 14.01 in windows XP the below call in the install.js in the XPI package is made.

var process = Components.classes['@mozilla.org/process/util;1']
				.getService(Components.interfaces.nsIProcess);
			process.init(file);
			var arguments= [] ; 
			process.run(true, arguments, arguments.length);  




Actual results:

The extension will begin to install then fire the process which runs the secondary installer ( setup.exe ).  This secondary installer will hang during the extension installation unless the browers is explicitly closed.  It appears to be a blocking incompatibility between XP and the latest FireFox.


Expected results:

The installer should run to completion.  

This issue is not present in Vista / Windows 7.  This issue consistently reproducible.

PSC, which extension were you using when you encountered this bug?

Comment 2

Changing component since this since this doesn't reproduce with all extensions.
