#186 Kdiff doesn't work with remote folders using fish protocol


Kdiff doesn't work with remote folders. If I recall correctly it used to work in Kubuntu 13.10 (Saucy) but not in 14.04 (Trusty). See https://launchpad.net/ubuntu/+source/kdiff3 for the differences

Example 1
A: file:///home/joan/
B: fish:/joanmaspons@

Error while open folders:
Direcory B «file:///home/joan/fish:/joan@» doesn't exists or it isn't a directory.

Example 2
A: fish:/joan@
B: file:///home/joan/

No server name was specified.

Error while open these files:
- fish:/joan@
- file:///home/joan/

Notice that in example 1 the path to directory B in the error message is wrong.

I translated the error message from catalan by myself so maybe the original strings differs.

    Please test with another program as well (e.g. Konqueror)
    Since KDiff3 just uses the KIO protocoll, such problems are usually not specific to KDiff3.

    And try two slashes: fish://...

    The fish protocol works with dolphin and konqueror.

    I tried with two slashes and the problem persist. Anyway, I used the file picker dialog with the bookmarks from dolphin so it should work as in dolphin.

    Same behaviour and same error with samba protocol!
    On Linux 3.12.13-gentoo 64bit

    I enter a folder name by searching it using the directory button. Then the directory name in line B: is correct:


    Then I click OK and get the error message

    Directory B "home/rudi/smb:/irp-notebook/Daten" does not exist or is no directory.
    Ordner B "home/rudi/smb:/irp-notebook/Daten" existiert nicht oder ist kein Ordner.

    And the previously correct directory in line B: is changed to

    I tested it with smb protocol and Konqueror - that works!

    It looks like file name handling in KDiff3 does not handle protocol name strings properly...

    I think it is a bug in KDiff3 and not in KIO.
    Comparing files does work, but comparing folders does not work !
    The error message is different depending on folder A is remote or folder B.

    Example 1:
    A: smb://mynas/username/folder1
    B: file:///home/username/folder1
    ERROR message: smb://mynas/username/folder1 is a folder while a file was expected.

    Example 2: (switch A <-> B)
    A: file:///home/username/folder1
    B: smb://mynas/username/folder1
    ERROR message: file:///home/username/smb:/mynas/username/folder1 does not exist or is not a folder.

    Note: The errormessages are not exact, because i got a Dutch installation of Ubuntu and i translated it to English.

    Comparing folders is an important feature for me, because i compare large directory trees (mostly my pictures) for backup purpose. (I use only file-size which is quick and safe enough for pictures).
    It works on my laptop where i still have Ubuntu 12.04

    Please try again with KDiff3 0.9.98. (Available as source)

    I tested version 0.9.98 with samba protocol - it is working - thank you!

    The progress bar number one always shows 0%, but repairing this item would be just a cosmetic improvement. The whole rest seems to work properly.

    Compiled and tested 0.9.98. Many thanks for fixing it.
