UNC paths from command line in trac-admin corrupted

[twoods-trac@…]

On Windows, when using a UNC path with backslashes as an argument to trac-admin like the following:

python trac-admin \path\to\projenv hotcopy \\server\folder\path\to\backup

The following output is produced:

Hotcopying \path\to\projenv to \\\\server\\folder\\path\\to\\backup ...Command failed: [Errno 2] No such file or directory

Executing the hotcopy command within the trac-admin shell with the same path succeeds.

A workaround is to use forward slashes in place of the backslashes on the command line for the UNC path.

It looks like the problem occurs when building the string to pass to onecmd at admin.py line 1227​. The input args list contains the correct UNC string, however in the s_args string all of the backslashes are doubled.

Don't know if it is expected but using forward slashes can work around this problem:

trac-admin C:\data\Projets\trac\Project hotcopy nas/Trac/Backup/Project
