403873 - install-global-extension fails with no error when the extension path is on a UNC network share

Status: RESOLVED INVALID

(Thunderbird :: General, defect)

Description

[cuicui.oizo]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; fr; rv:1.8.1.9) Gecko/20071025 Firefox/2.0.0.9
Build Identifier: Thunderbird 2.0.0.9 (Windows/20071031)

When launching thunderbird from CLI with the "-install-global-extension" option, the extension isn't installed (with no error) when its path is an UNC public network share (eg. \\server\ext\my_extension.xpi). Works fine when the path is local to the computer (eg. c:\ext\my_extension.xpi)

The previous version (TB 2.0.0.6) do not have this problem.

Reproducible: Always

Steps to Reproduce:
1. Launch thunderbird from a CLI with option "-install-global-extension" and a path to an extension that is localted on a UNC readable network share (eg. "c:\Program Files\Mozilla Thunderbird\thunderbird.exe" -install-global-extension \\server\ext\my_extension.xpi)
Actual Results:  
Nothing happends: no error is given, the extension isn't installed.

Expected Results:  
Thunderbird should install the extension globally or throw and error when failing.

Possible workaround:

 - copy the extension locally on the disk before invoking thunderbird with the "-install-global-extension" and give local path to the extension

 - stay in Thunderbird version 2.0.0.6

 - try to provide a "network drive" path to the extension instead to a UNC path (not tested)

See bug 399973, comment #0, specifically:
Use of the install-global-extension and install-global-theme command line arguments have been restricted to only allow installing add-ons that are on local disks or mapped drives. Installing from a network share directly will no longer succeed.

I'll see if I can update the relnotes for Thunderbird with this information.
