Subject: .ora files look like zip archives! (... really openraster support
 bugs: no mime-info, no thumbnailer)
Date: Sun, 06 Sep 2009 22:56:05 +0100

Package: mypaint
Version: 0.7.1-1
Severity: minor

OpenRaster files created by MyPaint are indistinguishable from Zip 
archives when viewed in Nautilus, to the extent of being shown with an 
incorrect MIME type (application/zip instead of image/openraster). Plus 
of course the icon is that of a zipfile.


Breaking it down, this is really another two-issue bug report (sorry) 
but these really are related, I promise!

1. MyPaint does not ship with a mime-info entry for OpenRaster files, 
meaning that ORA files appear in file manager programs as though they 
were ZIP archives.

2. Since the package is targeted at artists and visually-thinking 
people, it'd be really nice to have a thumbnailer for the most common 
desktop environments :)


Perhaps a new package for openraster desktop support could be created 
for these two issues together? Fixing 1. is a prerequisite of fixing 2. 
There's software available out there for this:

http://create.freedesktop.org/wiki/OpenRaster
http://gitorious.org/mypaint/mypaint/commit/043b64da68d47718fd96e64d04d710a46592526a

and it certainly wouldn't be something limited to just MyPaint: Krita 
(SVN), Drawpile, and GIMP (via the unofficial ORA loader/saver plugin) 
would all benefit. Initially it could live in the mypaint package I 
suppose, since mypaint is the program which would most immediately benefit.

I was wondering whether MyPaint should really have this mime?  Anyway, there
is one in the source in desktop/mime/mypaint.xml.  And Krita also has one,
not sure if it gets installed, but it's probably somewhat different.

Wouldn't there be conflicts if more than one application installs this?

I fully agree. The thing (if I'm up-to-date) is that we haven't figured out
yet whom to ask to integrate those thumbnailers into which project.

I was planning to move thumbnailers and mime stuff also into the oratools
repository (where the GIMP plugin is), away from the mypaint source, until
the respective desktop environments take over maintainence.  Do you think
this should grow into its own independent project instead, for distributions
to package?

Martin

[Cc:ed the named Debian krita maintainers and Bernd (maintainer of 
gimp-plugin-registry). Hi guys; Martin is the upstream maintainer of 
oratools, a bundle of plugins and desktop support for the OpenRaster 
file format: http://gitorious.org/mypaint/oratools . Any comments?]

Provided everything uses different files, then shared-mime-info 
shouldn't get too confused when it updates. It's still better practice 
to put behaviour only in one place, I think.

As far as oratools - yourself and Jon - are concerned, oratools could 
just package the mime-info XML and the thumbnailer scripts (disclaimer: 
I've not played with the KDE one), plus the existing GIMP package. Leave 
the installation details to the distros. It's still useful to have 
everything in one place, for everyone's sake.

Ana Beatriz, Raúl: would that seem acceptable from a KDE/krita 
perspective? I've no idea how KDE integrates thumbnailers, sadly.

(To fulfil the expectation created by the "tools" name, perhaps oratools 
could bundle some conversion scripts as well as the desktop and gimp 
integration stuff...? :)

Seems like the best plan, simply from the perspective of keeping 
everything in one place for maintainers. Making it fully independent of 
mypaint might be a nice thing too, from a political perspective... :)


One caveat from the packaging perspective: don't force KDE stuff on 
Gnome people or /vice versa/. If I were packaging for Debian, I'd split 
it into:

  oratools:
    Description: MIME setup and GIMP plugin for OpenRaster images
    Recommends: oratools-thumbnailer-gnome | oratools-thumbnailer-kde
    Enhances: gimp
    Depends: shared-mime-info
    Suggests: oratools-thumbnailer-gnome | oratools-thumbnailer-kde

  oratools-thumbnailer-kde:
    Description: KDE thumbnailer for OpenRaster images
    Enhances: kdebase
    Depends: oratools, $KDE_STUFF

  oratools-thumbnailer-gnome:
    Description: GNOME-style thumbnailer for OpenRaster images
    Enhances: gnome-desktop-environment, thunar
    Depends: oratools, $GNOME_STUFF

and arrange for actual paint programs which use OpenRaster - krita, 
mypaint - to use

  Recommends: oratools-thumbnailer-gnome | oratools-thumbnailer-kde

With this setup, people grabbing mypaint or krita using a Debian package 
manager that automatically selects Recommended packages should 
automatically pull in the right thumbnailers for their system.



Thunar uses GNOME-style thumbnailers if they're available, according to 
http://goodies.xfce.org/projects/thunar-plugins/thunar-thumbnailers/

Seems like KDE use shared-mime-info these days:
http://lists.kde.org/?l=kde-core-devel&m=117439505315489 , but their own 
style of binary thumbnailer blivets.

krita has handled this on its way and ship:

cat /usr/share/mime/packages/krita_ora.xml

<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
  <mime-type type="image/openraster-archiving">
  <comment>OpenRaster (long-term) Archiving document</comment>
  <glob pattern="*.ora"/>
</mime-type>
</mime-info>

So for krita users it is shown corrently. Actually, I think it better should be 
handled direclty by /usr/share/mime/packages/kde.xml.

In any case, why you do not submit the definition to share-mime-info upstream
and it is shown consistentely in all the desktops? Even if you do not have
any of the mentioned programs installed users can know what the file is about.

[Message part 1 (text/plain, inline)]

Hello,

I am developer, who usually helps also about mimetypes in KDE.
I looked at the current situation, and given there is some agreement on a 
common format, I did the following:
- created a mimetype definition for the image/openraster (with both glob and 
content match) basing on the mypaint wiki pages, and added it today (along 
with an example file found on mypaint site) to shared-mime-info's CVS
- synchronized krita to use this new version

this means that:
- any shared-mime-info version > 0.60 (current version is 0.60, so any 
released version from today) will have image/openraster available
- krita (in next released version, which will be the stable 2.1, in the end) 
uses this version, albeit carrying a local copy of it (to avoid a dependency 
on a not-released-yet shared-mime-info version)

I guess this should solve the mimetypes issue of openraster files. If not, 
just ping me :)

Thanks! One problem solved.
