[win32] Cannot access home network on parallels

[Sudesh]

On mac parallels, on windows and vista ,cannot access home network through Elisa. I can goto network places -> windows network , and can see all computers in my domain and also copy shared folders. But when tried to access through Elisa->Home network can't enter home network. Attaching log files and screenshot.

Steps to reproduce.

1.Start Mac parallels
2.Start winxp/vista snapshot
3.Start Elisa
4.Goto home network , i.e Music->Home network or Video->Home network

Expected Result : Able to enter home network, see the computers in domain.

Current Result : Cannot enter Home network.

By "on windows and vista" do you mean "on XP and vista"?
Please avoid attaching zip files, it just makes it a pain to quickly read the log files.
For further investigation, here is the relevant bit of the log file:

Yes .I meant XP and vista snapshots on mac parallels.

[Olivier Tilloy (osomon)]

@Sudesh: can you still observe this issue with the latest Moovida?

[Sudesh (sudeshc-deactivatedaccount)]

Yes still cannot enter 'other computers' on xp ,vista VM images with similar stack trace as before.
Can enter 'other computers' on physical machines for large networks also , no problems there.

Stack trace while entering 'other computers' on Moovida(for windows VM) :

Could you please set the ELISA_DEBUG environment variable to "smb*:5" (without the surrounding double quotes) and run Moovida, reproduce the bug, exit and attach the resulting log file?

[Sudesh (sudeshc-deactivatedaccount)]

Please find attached log file for the issue.

[Olivier Tilloy (osomon)]

I can reliably reproduce on windows XP running in Parallels.
Bumping the importance to high, not so much for symptoms of the bug itself, but because it potentially keeps us from detecting other bugs related to the local network when testing in Parallels (where most of the testing happens today).

[Olivier Tilloy (osomon)]

I did a bit of investigation, and the culprit appears to be the Z:\ network drive ('Home' on .psf).

The exception is raised in elisa-plugins/elisa/plugins/smbwin32/smbwin32_resource.py at line 95:

    MediaUri("smb://" + server)

because server is None (which should of course not happen).

Putting a breakpoint at this place reveals that the value of self._shares is:

    {None: [MediaUri(u'file:////.psf/Home')]}

Anyone who will tackle this issue will have to go up the stack to understand why we end up with a None key in the dictionary of shares.
