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.

Visual Studio does not allow decorating functions with '__declspec (dllexport)'
if a prototype exists and is not decorated with '__declspec (dllexport)' as
well, so we cannot just decorate g_io_module_[load|unload|query] in the various
module sources with G_MODULE_EXPORT because the prototypes of these functions
have been marked with _GLIB_EXTERN, which equates to 'extern' unless overridden
Fix this by overriding _GLIB_EXTERN with the appropriate visibility flag, as we
have used to define _GDK_EXTERN. Unfortunately, we can't just use _GDK_EXTERN
G_MODULE_EXPORT as they may have not been defined yet for our use
Do this across the board for all modules, even if they are not buildable on
Visual Studio nor Windows, for consistency's sake.
It seems newer releases of CUPS removed the ability to disable
deprecation warnings by defining a pre-processor symbol, so we
have to resort to the usual begin/end ignore deprecation pragmas
to avoid a ton of deprecation warnings.
printer_name_compressed_strv is NULL-terminated array
of gchar*, which means N+1 memory should be allocated.
Otherwise, if the printer name has no empty components
(which is usually the case), printer_name_compressed_strv[N],
which should contain the NULL sentinel, will actually lie
just outside of allocated memory, which is UB.
In my case, it led to crashes inside g_strjoinv
when Print... dialog is opened in evince.

Device URI was not filled for non-Avahi printers by my previous commit.
I've added it back. It was a mistake during rebasing of the patch
to current master.
Create printer name from name of the advertised service
for standalone IPP printers as opposed to CUPS printers
advertised via Avahi which get name from their
resource path.
This is similar to what cups-filters does.
Pass GtkPrinter class to request for printer info
so that it does not need to be searched for
(such search could fail for standalone IPP printers).
https://gitlab.gnome.org/GNOME/gtk/issues/1509
Set reasonable default values for printers discovered
by Avahi which do not have 'printer-type' attribute.
This is the case for network printers which were not
published by CUPS.
Related to the issue #1509.
We were looking for the cups headers and the cups lib in the default locations
which for example breaks with OpenBSD where the cups headers are under /usr/local/include/
Instead just use the "cups" dependency type from meson which internally uses cups-config.
See #1967
Ported to master from !963
httpGetAuthString() was added with cups 1.3 and we depend on a newer version
now. The direct field access was a fallback in case httpGetAuthString()
was missing, so this can also be dropped.
Ported to master from !938
The http* family of functions was deprecated after CUPS 1.7. We can
conditionally use it when built against a newer version of CUPS. The
additional parameters are taken directly from the fallback values
inside CUPS itself.
Additional code improvements and fixes:
- Use g_regex_match_simple() instead of sscanf()
- Added spaces between function names and left parantheses
- Set always correct custom page size
- Added page_setup field to CupsOptionsData data structure
- Replaced tab indentions by spaces
- Moved #define out of add_cups_options() function, removed line breaks from regular expressions
We need to override _GLIB_EXTERN to export the required symbols for the
GIO module on Visual Studio, so that the media modules can be
successfully loaded.
We were leaking the GBytes for the image memory, which is a
noticeable memleak to anyone who's casually running a memory monitor.
Go KDE users!
Closes#1200
to retreive paper size specific hard margins and use this
to set the hard margins in the print context.

When using strncpy() with a buffer we need to account for the
terminating NUL character. GCC 8 started warning when using PPD_MAX_NAME
as the buffer length for strncpy() because the buffer we're copying into
has the same length — which means that the terminating NUL may be
skipped if the source string has a length of PPD_MAX_NAME.
The appropriate way to handle the case where we're copying a source with
a length bigger than of PPD_MAX_NAME is, as reported in the strncpy()
documentation, to copy `PPD_MAX_NAME - 1` bytes, and explicitly NUL
terminate the destination buffer. This has the additional benefit of
avoiding the compiler warning.
The main buildscript expects 'print_backends' list to be defined.
Since printbackends is os_unix-only, we need to define this list
ourselves for other OSes.
