Accessing objects with "[" or "]" in name via webdav results in "Invalid response"

[Roman Yepishev]

Distributor ID: Ubuntu
Description: Ubuntu 10.10
Release: 10.10
Codename: maverick

gvfs2-backends: 1.6.4-0ubuntu1.1

STR:
1. Create a file on webdav-enabled location with "[" in the filename
2. Attempt to access this file via gvfs/nautilus

Actual results:
"Invalid response" from nautilus
"Input/Output error" from ls on a .gvfs directory

Expected results:
These file name symbols should not affect the ability to access it through gvfs-webdav.

Thank you for your bug report, that seems an upstream issue in the gvfs dav backend

@Sebastien, yes, thanks for switching the project.

So, it turns out that the path checks are not very robust:

The path comparison uses the urlencoded strings but the case of hexadecimal letters is not preserved. E.g. for me it checks the following paths:

- /Downloads/test%20file%5bin_brackets%5d/
- /Downloads/test%20file%5Bin_brackets%5D

So after some kind of normalization these paths are different - %5b vs %5B and trailing slash is missing. Basically any character that will be urlencoded with A-F in the resulting hex will cause the first mismatch.

Here's a patch for gvfsbackenddav.c which fixes this issue.
