569460 → Filenames not unescaped

[Alexander Skwar <alexanders mailinglists+nospam gmail com>]

Hi!

A short while ago, I submitted Bug 569460 – Unescape special
charcters in filenames when doing (Flickr, Picasa Web, Zip, ...) export.
I now had a look at the source at ZipExport.cs, as that's the shortest
export source. And as all the exporters show the same problem, I thought
that one might be as good as another one...

In the ZipExport.cs of f-spot 0.5.0.3, I think that the method zip()
is the interesting one. In there, I'd guess that the line 126

  ZipEntry entry = new ZipEntry (photos [i].Name);

is interesting. Here, the name of the ZipEntry is taken to be the Name
of the photo. I haven't checked, but I suppose that this Name string
contains the escaped version of the filename, doesn't it? Ie., if
the filename is

[2008-11-12--10.40.37] (IMG_0017) Cédric, Photoshooting, Petra, Fotograf.jpg

then Name would be

%5B2008-11-12--10.40.37%5D%20(IMG_0017)%20C%C3%A9dric%2C%20Photoshooting%2C%20Petra%2C%20Fotograf.jpg

Correct?

I've got no knowledge at all about C#, but I think that what would
be required here is, that instead of photos[i].Name, the unescaped
version of the name is to be used.

In C#, is there a method which allows to easily unescape a
string? Ie. something, which translates stuff like "C%C3%A9dric"
to "Cédric"?

I guess that something like this already needs to be used in f-spot,
in order for f-spot to decode a file uri to a path, as only a file uri
(ie. file:///home/askwar/.......) is stored in the f-spot database. I
"browsed" the f-spot source, but haven't found the spot, where
f-spot tries to load a file from disk. I guess that's where f-spot
would do a decoding of the string stored in the database to get
the proper path name.

The reason why I bring that topic also here to the mailinglist
is, that this bug makes f-spot pretty much useless for me, as
it's certainly nice to be able to manage pictures locally - but
from time to time, an export to some public site, like Flickr,
PicasaWeb or whatever, would be good as well. And with
picturenames like
"%5B2008-11-12--10.40.37%5D%20(IMG_0017)%20C%C3%A9dric%2C%20Photoshooting%2C%20Petra%2C%20Fotograf.jpg"
that looks very bad.

I'd be very happy if one of you could give me a hand :)

Thanks a lot,

Alexander
