Packagers of plasmoids (Plasma applets): please run plasma-dataengine-depextractor in %build
by Kevin Kofler
Hi,
since I just noticed that even the newly submitted kde-print-manager was
missing this, here's a gentle reminder to all maintainers of Plasma applets:
in your specfiles, at the beginning of the %build section, please add
something like the following:
if [ -x %{_bindir}/plasma-dataengine-depextractor ] ; then
plasma-dataengine-depextractor plasmoid-package
fi
(The if check can be dropped once Fedora 16 reaches its end of life.) See:
https://fedoraproject.org/wiki/Features/Plasma_PackageKit_Integration
for why this is required.
The syntax of the plasma-dataengine-depextractor tool is:
plasma-dataengine-depextractor [path] [file]
where:
* "path" is the path to the source code of the plasmoid (relative to the
current directory) – defaults to "." and
* "file" is the file name or path (relative to "path", NOT to the current
directory) of the .desktop file – defaults to "metadata.desktop"
(If only one argument is specified, it will be interpreted as a "path", so
if you want to specify only "file", you have to pass "." explicitly for the
"path" argument.)
If you have multiple applets, then multiple calls to
plasma-dataengine-depextractor are needed.
The only case where this is not required is if the .desktop file shipped by
upstream already contains a:
X-Plasma-RequiredDataEngines=…
key (which may or may not be empty), but chances are it won't, because
upstream refused to merge the Plasma PackageKit Integration into kdelibs 4
(they want it in KDE Frameworks 5 only). But thankfully, only a
straightforward command is needed in the specfiles to autodetect the
dependencies.
Now, strictly speaking, it is also not technically required if either no
data engines are used at all (as in some very simple plasmoids) or all data
engines used are provided by the plasmoid package itself (as happens to be
the case for kde-print-manager), but IMHO it is still a good idea to run the
depextractor even in that case because a later updated version of the
plasmoid may start requiring additional data engines.
And before you ask why this is not done by the RPM auto-Requires script,
this is because that script does not necessarily have access to the source
code: Especially in the case of compiled (C++) plasmoids, the detection MUST
be done from the source tree. So the auto-Requires script just always
expects the depextractor to have been run, no matter what language the
plasmoid was written in.

KMail folder not appearing
by Timothy Murphy
I'm running KMail on my Fedora-17/KDE laptop,
collecting email from an dovecot/IMAP server
on a remote CentOS-6.3 machine that I control.
I created a new KMail folder "MathProblems"
by going to File=>New=>Add Folder on my laptop,
and I verified that this created a folder ~/Mathdir/.MathProblems
on the dovecot server (which stores email in ~/Mathdir),
with the usual cur, new, tmp sub-folders.
However, the files dovecot.index, dovecot.index.cache, etc,
do not appear in the .MathProblems folder
as they do in other similar folders,
and the folder does not appear in KMail on my laptop.
Is this a KMail or Dovecot bug?
And is there any way of creating the missing files?
Any advice or suggestions gratefully received.

kde failure after update on fedora 17
by Mark Gaudry
I maintained updates on my Fedora 17 system regularly. About 4 updates
back most of my kde based programs stopped working. I kept adding updates
with the hope that the problem would be solved. It has only gotten worse.
I can no longer run apper or the updater from the notification icon. What
have I done wrong or installed that might be causing this? I have
installed multiple user interfaces and choose the one I use from the login
screen listings. Could one of the others be conflicting somehow? If so
which one is usually the worst culprit? I'll go in with one of the more
reliable alternatives and remove the bad one(s). Any other ideas are also
greatly appreciated.

Plasma Netbook or Active on Fedora ?
by linux guy
Is Plasma Netbook still around ?
Is Plasma Active 3 ready for semi production use ? It can't be worse
than Jelly Bean, can it ?
Is there an easy way to install either of these on an existing Fedora
install without wrecking it ?
I'd really like to give one or both of them a try.
Thanks
