This reduces the build-time dependencies of glib to only Python 3,
Meson, and git. Git is also optional if you provide a tarball in
which the subproject directories already exist.
The Python port was done by Jussi Pakkanen on bugzilla:
https://bugzilla.gnome.org/show_bug.cgi?id=779332
This version contains some fixes from that and also changes all
instances of `@` to `\u0040` because Meson does not yet provide a
configure_file() mode that ignores unknown @MACRO@ values.
This is a stub-only library that can be used while building against
MSVC and contains no i18n machinery at all.
The dependencies added indirectly use the libintl.h header, and when
built as a subproject, the header won't be in a path known the
pre-processor.
Don't use it project-wide for building everything. Otherwise
symbols for shared modules won't be exposed, e.g. in the
resourceplugin used by the gio resource unit test.
Disable gio tests on Windows, fix .gitignore to not ignore
config.h.meson, and add more things to it.
Rename the library file naming and versioning to match what Autotools
outputs, e.g., libglib-2.0.so.0.5000.2 on Linux, libglib-2.0-0.dll and
glib-2.0-0.dll on Windows with MSVC.
Several more tiny fixes, more executables built and installed, install
pkg-config and m4 files, fix building of gobject tests.
Changes to gdbus-codegen to support out-of-tree builds without
environment variables set (which you can't in Meson). We now add the
build directory to the Python module search path.
We're in the process or rewriting other tools in Python to reduce the
number of dependencies of GLib.
Additionally, making glib-genmarshal a Python script reduces the
complexity when cross-compiling, as we don't need a native build to
generate the marshallers.

It is possible, when using GTK-Doc, to mark sections of an enumeration
type as "private": the values are there, but they are not documented,
and GTK-Doc won't complain about missing symbols:
typedef enum {
/*< private >*/
MY_FOO_PRIVATE,
/*< public >*/
MY_FOO_VALUE_A,
MY_FOO_VALUE_B,
/*< private >*/
MY_FOO_VALUE_C,
MY_FOO_VALUE_D
} MyFooValue;
The glib-mkenums parser also allows skipping enumeration values, using a
slightly different syntax:
typedef enum P
MY_BAR_PRIVATE, /*< skip >*/
MY_BAR_VALUE_A,
MY_BAR_VALUE_B
} MyBarValue;
The annotation must sit on the same line as the enumeration value.
Both GTK-Doc and glib-mkenum use the same trigraph syntax, but slightly
different keys. This makes combining them slightly redundant, but
feasible.
All would be well and good, except that glib-mkenum will generate a
warning for lines it does not understand — and that includes the GTK-Doc
annotation trigraph, which, when confronted with the MyFooValue
enumeration above, will result in a warning like:
glib-mkenums: myfoo.h:2: Failed to parse ` /*< private >*/ '
glib-mkenums: myfoo.h:5: Failed to parse ` /*< public >*/ '
glib-mkenums: myfoo.h:9: Failed to parse ` /*< private >*/ '
Of course, we could make glib-mkenum ignore any trigraph comment on a
stand alone line, but it would probably be better to ensure that both
glib-mkenums and gtk-doc behave consistently with each other, and
especially with the maintainer's intent of hiding some values from the
user, and reserving them for internal use.
So we should ensure that glib-mkenums automatically skips all the
enumeration values after a "private" flag has been set, until it reaches
a "public" stanza.

This way code that does not manually include the generated marshallers
header and wishes to build with `-Wmissing-prototypes` will not generate
a compiler warning.

It's unnecessary, and only adds visual noise; we have been fairly
inconsistent in the past, but the semi-colon-less version clearly
dominates in the code base.

This is going to be checked again by g_object_new_with_properties()
and g_object_new_valist() anyway, so might just as well leave it
to those functions to do the check and only do it once. It doesn't
matter which function emits the critical warning in the end either,
as one has to look at a stack trace to find out what code triggered
it in any case.

g_object_newv uses a GParameter as argument. Since GParameter
is deprecated due to this type is not introspectible,
g_object_newv is deprecated now.
https://bugzilla.gnome.org/show_bug.cgi?id=709865
g_object_new_with_properties is an alternative to g_object_newv.
The last one, takes an array of GParameter. However, GParameter
is a rarely used type and this type is not introspectible, so
it will not work properly in bindings.

They do not start with the #!/usr/bin/python that would be necessary
to make them run with Python rather than a shell, and they would
not be useful to run anyway: they are libraries to be imported,
not scripts to be run.

It was suggested that the project files be moved here as we don't actually
need to go two directory layers from $(srcroot), and would help us to
standardize on things in the future across the board.
The macros differ in their handling of NULL values — some macros ignore
them and pass through (e.g. G_TYPE_CHECK_INSTANCE_CAST) while others
will explicitly emit a warning if passed NULL (e.g.
G_TYPE_CHECK_INSTANCE).
Document their behaviour, so people don’t end up putting unnecessary
NULL checks in their code when doing checked type casts.

glibc string.h declares memcpy() with attribute(nonnull(1,2)), causing
calls with NULL arguments to be treated as undefined behaviour.
This is consistent with ISO C99 and C11, which state that passing 0
to string functions as an array length does not remove the requirement
that the pointer to the array is a valid pointer.
gcc -fsanitize=undefined catches this while running OSTree's test suite.
Similarly, running the GLib test suite reports similar issues for
qsort(), memmove(), memcmp().

global variables in SystemTap are shared between all SystemTap scripts;
so if scripts are loaded for two versions of GLib (for example, a stable
and a development version), those global variables will conflict.
Avoid that by including the soname’s version in the global variable
names.

If we have an input parameter (or return value) we need to use (nullable).
However, if it is an (inout) or (out) parameter, (optional) is sufficient.
It looks like (nullable) could be used for everything according to the
Annotation documentation, but (optional) is more specific.
gtk-doc doesn’t make the return type clear, because these are macros
rather than inline functions, so people often have to guess at the
return type (or look it up from g_signal_connect_closure(), but that’s
hard work).
Make it clear that the return type for handler IDs is gulong. While
there, fix the capitalisation of ‘id’ to ‘ID’ in a few places.
