system-config-printer-common-1.4.3-r1-split.patch

Description Kirill Elagin 2013-02-10 00:22:06 UTC
I'm trying to add a printer, published via dns-sd (by printserver running CUPS+Avahi).

When I run print-manager, and click “New printer”, my printer is discovered, but there is a red error “The name org.fedoraproject.Config.Printing was not provided by any .service files”. If I close the window and open it again, the printer is discovered and this error is displayed sometimes, and sometimes there is no error and no printer. It seems to be a bit random for now…

This brand new emerge --info is so awesome it won't fit in the comment field.
Comment 2 Ian Whyman (thev00d00) (RETIRED) gentoo-dev 2013-02-14 21:31:30 UTC
Strangely this is provided by app-admin/system-config-printer-gnome
Comment 3 Andreas K. Hüttel archtester gentoo-dev 2013-05-26 19:39:57 UTC
Which print-manager version was that? Do you still have the problem with 4.10.3?

> Which print-manager version was that?
I have no idea. Which was the latest unstable at the time the bug was created?

Just tried with 4.10.3. The error now looks more beautiful and appears _every time_, not randomly.
Comment 5 Kirill Elagin 2013-05-26 20:00:43 UTC
(I should probably note that, obviously, I removed app-admin/system-config-printer-gnome before trying. The error disappeared when I reinstalled it.)
Comment 6 Andreas Sturmlechner gentoo-dev 2013-06-09 09:03:47 UTC
Same here with KDE SC 4.10.4.

Without system-config-printer-gnome, I always get the error message when adding a printer, but my network printer is well discovered.

Having system-config-printer-gnome emerged, the error message is gone, but gone as well is the list of discovered printers.
Comment 7 Andreas Sturmlechner gentoo-dev 2013-06-09 09:09:42 UTC
I just forgot to restart dbus. Done that, and the printer is discovered now.
Comment 8 Andreas K. Hüttel archtester gentoo-dev 2013-06-09 09:15:47 UTC
added runtime dependency on app-admin/system-config-printer-gnome
(this does not pull in any gnome packages usually, don't worry)
Comment 9 Nikoli 2013-06-09 12:36:32 UTC
system-config-printer dep is indeed required:
print-manager-4.10.3 $ grep -Ri org.fedoraproject.Config.Printing|wc -l
9

But having app-admin/system-config-printer-gnome in RDEPEND is ugly: it wants old and obsolete pygtk.

Why /usr/share/dbus-1/interfaces/org.fedoraproject.Config.Printing.xml
and related files are not in system-config-printer-common package? Having them in system-config-printer-gnome is pointless.

system-config-printer-* packages should be fixed and dep changed to app-admin/system-config-printer-common

Even ubuntu has it done much better:
http://packages.ubuntu.com/raring/system-config-printer-common
http://packages.ubuntu.com/raring/system-config-printer-udev
http://packages.ubuntu.com/raring/system-config-printer-gnome
Comment 10 Maciej Mrozowski gentoo-dev 2013-06-09 13:25:07 UTC
Reopening and reassigning. Dependency on scp-gnome is not the way to go. I'' consider splitting rearrangig stuff in scp (maybe create separate ebuild for dbus interface) once I know what print-manager actually needs...
Comment 11 Jouni Rinne 2013-08-12 17:10:42 UTC
This should be resolved fast, because the new system-config-printer-gnome-1.4.1 has quite a huge amount of gnome/gtk3 dependencies. /me going to mask 1.4.1 until fixed.
Comment 12 Andreas Sturmlechner gentoo-dev 2013-12-01 11:01:33 UTC
I've tried to split scp like they do in Ubuntu, but in 1.4.3 the following line has appeared in scp-dbus-service.py, which gets called by print-manager when searching for printers:

from gi.repository import Gdk


So I'm currently stuck here:

ERROR:root:Could not find any typelib for Gdk
Traceback (most recent call last):
  File "/usr/share/system-config-printer/scp-dbus-service.py", line 26, in <module>
    from gi.repository import Gdk
ImportError: cannot import name Gdk


A dependency on x11-libs/gdk-pixbuf[introspection] didn't help, so maybe gtk+:3 is needed here for whatever reason...

system-config-printer-common-1.4.3-r1-split.patch

keep more stuff in -common for use with kde-base/print-manager
Comment 14 Andreas Sturmlechner gentoo-dev 2013-12-01 12:54:22 UTC
Removed the Gdk calls, but then further down the code in scp-dbus-service.py they import jobviewer.py, which itself depends on gtk, pango etc. again. I had removed jobviewer.py in the 1.4.3-r1-split.patch as seen from the files list of Ubuntu, but that means they must have a circular dep scp-common <-> scp-gnome...

It seems to me a sane split where print-manager can really depend just on scp-common is not possible without serious code mangling.
Comment 15 kavol 2014-03-21 16:33:24 UTC
I'm pretty confused ... seems that I'm missing something, can someone explain why
kde-base/kdeutils-meta has a dependency chain that explicitly blocks kde-base/system-config-printer-kde and depends on app-admin/system-config-printer-gnome instead?

I could find some clue in comment #12 that printer-manager depends on that -gnome thing, but why don't we go with the -kde thing in the first place?

> kde-base/system-config-printer-kde and depends on

Where did you find kde-base/system-config-printer-kde?
There is no such ebuild in the portage tree right now as system-config-printer-kde has been deprecated some time ago in favour of kde-base/print-manager.

um ... /usr/portage/kde-base/print-manager/print-manager-4.12.3.ebuild

RDEPEND="${DEPEND}
        !kde-base/printer-applet:4
        !kde-base/system-config-printer-kde:4
        !kde-misc/print-manager

> There is no such ebuild in the portage tree right now

I haven't gone so far in investigation, sorry, my overlook

don't know the reasons behind the change, but IMO, better to deprecate without replacement than to replace with GNOME stuff - those who want it can install it explicitly, and those who want to save resources (like me :-)) are not exactly happy finding out that tons of irrelevant stuff had sneaked in as dependencies of what is supposed to have nothing with that stuff ...

I agree.
It was not the case until recently that system-config-printer-gnome pulled Gnome stuff. Seems that something has changed recently, unfortunately.
Comment 19 Maciej Mrozowski gentoo-dev 2014-04-27 23:10:27 UTC
To me this is really upstream bug - print-manager not handling scp (optional runtime dependency) gracefully/predictably.
Comment 20 Kirill Elagin 2014-04-28 07:23:16 UTC
I think it's been handling it predictably for a while now (see comment #4).
And anyway, they claim it to be scp bug.
Comment 21 Pacho Ramos gentoo-dev 2014-10-18 17:50:09 UTC
What gnome stuff is people trying to avoid here? scp has "gnome" name but I only see this dependencies there:
        ${PYTHON_DEPS}
        ~app-admin/system-config-printer-common-${PV}
        dev-python/pycairo[${PYTHON_USEDEP}]
        >=dev-python/pycups-1.9.60[${PYTHON_USEDEP}]
        dev-python/pygobject:3[${PYTHON_USEDEP}]
        x11-libs/gtk+:3[introspection]
        x11-libs/libnotify[introspection]
        x11-libs/pango[introspection]
        gnome-keyring? ( gnome-base/libgnome-keyring[introspection] )


Then... all this splitting (that causes us to be slower to bump scp as we are the only distribution doing that splitting and are a bit alone for that then) is for avoiding gtk+:3 dep? (because, seriously, people should really really try to use pygobject:3 instead of the completely dead and semi-broken :2 slot)
Comment 22 Pacho Ramos gentoo-dev 2014-10-18 17:51:10 UTC
Well, even the KDE upstream doesn't agree with this splitting:
https://bugs.kde.org/show_bug.cgi?id=320326

Comment 23 Luke-Jr 2014-10-18 17:53:12 UTC
Personally, my preference is to hard-mask dev-libs/glib (locally, of course).

The splitting does not really work, and at the same time upstream says s-c-p is not really mandatory. So, I would opt for

1) get rid of it
2) make it an optional dep in print-manager (what USE-flag then?)
3) call for a more descriptive _warning_ instead of that useless _error_ message, after all, I can add my printer just fine in print-manager without having s-c-p installed, only without the helping hand wrt device grouping
Comment 25 Maciej Mrozowski gentoo-dev 2014-10-20 20:05:59 UTC
+1 from me.
Comment 26 Michael Palimaka (kensington) gentoo-dev 2014-11-24 17:22:18 UTC
We hide the dependency behind gtk USE flag lately, so I guess we're done.
