Print backend can be disposed together with all its printers
as a reaction to user stopping enumeration of printers.
Adding a weak pointer help us to detect that the backend
was disposed and hence the backend and its printers should not
be used anymore.
Fixes#6265
It started out as busywork, but it does many separate things. If I could
start over, I'd take them apart into multiple commits:
1. Remove G_ENABLE_DEBUG around GDK_DEBUG_*() calls
This is not needed at all, the calls themselves take care of it.
2. Remove G_ENABLE_DEBUG around profiling code
This now enables profiling support in release builds.
3. Stop poking _gdk_debug_flags and use GDK_DEBUG_CHECK()
This was old code that was never updated.
4. Make !G_ENABLE_DEBUG turn off GDK_DEBUG_CHECK()
The code used to
#define GDK_DEBUG_CHECK(...) false
#define GDK_DEBUG(...)
which would compile away all the code inside those macros. This
means a lot of variable definitions and debug utility functions
would suddenly no longer be used and cause compiler errors.
The Common Print Dialog Backends (CPDB) concept has GUI-toolkit-independent
backends for each print technology (CUPS, Print to File, cloud printing
services, ...) and each print dialog (GTK, Qt, Chromium, ...) is supposed
to use this backend, so that changes in print technologies can be centrally
and quickly covered by changing the backends and everything new gets available
in all print dialogs.
This commit provides a GTK print dialog backend to add support for the CPDB
concept. It communicates with all installed CPDB backends and so gives support
for all these print technologies to the GTK print dialog.
To make use of CPDB the GTK print dialog is supposed to be installed with this
backend and the 'Print To File' backend, and not any others to prevent printer
duplication.
This reverts commit acd9c12667.
This commit breaks the build with GLib main on all platforms,
and defining _GLIB_EXTERN arguably invades the GLib namespace.
A different fix for msvc will have to be found.
Those property features don't seem to be in use anywhere.
They are redundant since the docs cover the same information
and more. They also created unnecessary translation work.
Closes#4904
GModule requires the .so file extension on macOS for historic reasons.
However Meson defaults to .dylib for modules, so we need to override
it to get the correct extension.
Fixes#3645.
This commit unsubscribes CUPS backend from a DBus
signal in idle when listening for new items on Avahi.
Since GDBus emits gathered signals in idle while
checking whether the signal has been unsubscribed
it could happen that a signal was not processed
because it was removed from hash table of
subscribed signals.
This caused the situation where printers advertised
on Avahi were not listed in CUPS backend sometimes.
We need those signals since this happens when switching
from a general subscription which listens to signals
for all Avahi services to a specific one which listens
to just _ipp._tcp and _ipps._tcp (chicken and egg problem).
This change extends set of Avahi advertised printers which
works with Gtk's CUPS print backend.
It creates a temporary queue (local printer) for each
Avahi printer in CUPS instead of accessing them directly
(via CUPS library).
This makes some printers work which did not work before and
also gives users more options to change in the print dialog.
This also changes naming of printers to be in accordance with CUPS.
It uses '_' instead of '-' and has hostname appended for CUPS remote
printers.
This gracefully disable ffmpeg, gstreamer, cups and cloudprint optional
dependencies when they are not available, while still giving full
control to distributors using -Dauto_features=enabled.
This reverts commit d761e3cf2c.
I am seeing PPD_CUSTOM_UNKNOWN in the cups headers in our
ci images, and that is cups 2.2.12. So this commit was
mistaken.
Use feature options for things that are optional features,
update the docs.
Visible changes here is that the 'print-backends' option
got renamed to 'print' to go better with 'media', and the
'tracker3' option got renamed to 'tracker'.
For options that have been changed into features, the
syntax now is -Dfeature=enabled or -Dfeature=disabled
or -Dfeature=auto.
CUPS uses resource paths in the form of "printers/printer_name"
or "classes/class_name" so it is enough to remove the "printers/"
or "classes/" prefix and use the string behind it as a name.
There was recently introduced a wrong check for the prefix.
This commit fixes it in the way it was originally intended.
G_DEFINE_DYNAMIC_TYPE declares these functions as static, and
-Werror=redundant-decls won't let us redeclare them. This is the
equivalent of 72c72d0b, but for a different backend.
