I don't know what's wrong but I can't add a file with the mercurial backend (the file is created but not added).

Here is a patch that's seems to work, although I'm not quite sure what's wrong with current code :

 sub rcs_add ($) {
        my ($file) = @_;

-       my @cmdline = ("hg", "-q", "-R", "$config{srcdir}", "add", "$file");
+       my @cmdline = ("hg", "-q", "-R", "$config{srcdir}", "add", "$config{srcdir}/$file");
        if (system(@cmdline) != 0) {
                warn "'@cmdline' failed: $!";
       }

My srcdir path has some symbolics links and hidden directorys... maybe that's it ?

Interesting, the mercurial test suite shows the add without the path working ok. OTOH, it also continues to work if I apply your patch, so I guess it's safe enough. It would be good to know why it's failing w/o the path in your case. --Joey

I didn't have time to investigate, but here is the path :

 /home/hbernard/.hiddendatas/hg/ikigtd/

but ~/.hiddendatas is itself a symbolic to .dotfiles/.hiddendatas (this seems weird I know ;)) As I was trying to resolve this, the interesting thing is that keying directly in a terminal the same command was working... I suspect something with the symbolic link... but didn't investigate further. I will setup a test wiki with symlink in the path to check this.

As I applied the patch, I'm moving this out of the patchqueue to bugs and marking it done. --Joey
