Some editors automatically remove trailing blank lines, or
automatically add a trailing newline to avoid having a trailing
non-blank line that is not terminated by a newline. To avoid unrelated
whitespace changes when users of such editors contribute to GLib,
let's pre-emptively normalize all files.
Unlike more intrusive whitespace normalization like removing trailing
whitespace from each line, this seems unlikely to cause significant
issues with cherry-picking changes to stable branches.

The various `g_strdup_printf()` returns values in the implementations of GValue
lcopy_func are runtime checks which could be disabled if one wants and therefore
should be handled as such with g_return_val_if_fail()
The property strings are interned already, so this potentially allows for faster
comparisons. The property strings were already not copied, as they were tagged
as static.
This adds support to be able to explicitely stored interned strings into
G_TYPE_STRING GValue.
This is useful for cases where the user:
* *knows* the string to be stored in the GValue is canonical
* Wants to know whther the string stored is canonical
This allows:
* zero-cost GValue copy (the content is guaranteed to be unique and exist
throughout the process life)
* zero-cost string equality checks (if both string GValue are interned, you just
need to check the pointers for equality or not, instead of doing a strcmp).

The glib-mkenums program allows generating code to handle enums/flags
with very different purposes. One of its purposes could be generating
per-enum/flag methods to be exposed in a library API, and while doing
that, it would be nice to have a way to specify in which API version
the enum/flag was introduced, so that the same version could be shown
in the generated API methods.
E.g. From the following code:
/**
* QmiWmsMessageProtocol:
* @QMI_WMS_MESSAGE_PROTOCOL_CDMA: CDMA.
* @QMI_WMS_MESSAGE_PROTOCOL_WCDMA: WCDMA.
*
* Type of message protocol.
*
* Since: 1.0
*/
typedef enum { /*< since=1.0 >*/
QMI_WMS_MESSAGE_PROTOCOL_CDMA = 0x00,
QMI_WMS_MESSAGE_PROTOCOL_WCDMA = 0x01
} QmiWmsMessageProtocol;
The template would allow us to generate a method documented like this,
including the Since tag with the value given in the mkenums 'since' tag.
/**
* qmi_wms_message_protocol_get_string:
* @val: a QmiWmsMessageProtocol.
*
* Gets the nickname string for the #QmiWmsMessageProtocol specified at @val.
*
* Returns: (transfer none): a string with the nickname, or %NULL if not found. Do not free the returned value.

Meson 0.54.0 added a new method meson.override_dependency() that must be
used to ensure dependency consistency. This patch ensures a project that
depends on glib will never link to a mix of system and subproject
libraries. It would happen in such cases:
The system has glib 2.40 installed, and a project does:
dependency('glib-2.0', version: '>=2.60',
fallback: ['glib', 'glib_dep'])
dependency('gobject-2.0')
The first call will configure glib subproject because the system libglib
is too old, but the 2nd call will return system libgobject.
By overriding 'gobject-2.0' dependency while configuring glib subproject
during the first call, meson knows that on the 2nd call it must return
the subproject dependency instead of system dependency.
This also has the nice side effect that with Meson >0.54.0 an
application depending on glib can declare the fallback without knowing
the dependency variable name: dependency('glib-2.0', fallback: 'glib').
The __declspec(dllexport) attribute in itself doesn't imply
'extern' - thus any intended variable declaration with
GLIB_VAR/GOBJECT_VAR would actually be a variable definition. With
C compilers defaulting to -fcommon, this isn't an issue, but
upcoming compilers (GCC 10 and Clang 11) will default to -fno-common,
ending up with duplicate definitions of these variables.
Rename the variables involved so that people get a slightly more
obvious critical warning when they try to ref an object which has
already been finalised.

Making this validation code public allows projects to validate a
GParamSpec name before creating it. While hard-coded GParamSpec don't
need this, we can't afford crashing the main program for dynamically
generated GParamSpec from user-created data.
In such case, we will need to validate the param names and return errors
instead of trying to create a GParamSpec with invalid names.
Includes modifications from Philip Withnall and Emmanuele Bassi to
rearrange the new function addition and split it into one function for
GParamSpecs and one for GSignals.
When calling `g_set_object()` for a type derived from `GObject`, GCC 9.2
was giving the following strict aliasing warning:
```
../../source/malcontent/libmalcontent-ui/user-controls.c:1001:21: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]

744 | (g_set_object) ((GObject **) (object_ptr), (GObject *) (new_object)) \
| ^~~~~~~~~~
```
This was due to the `(GObject **)` cast.
Pass the pointer through a union to squash this warning. We already do
some size and type checks of the dereferenced type, which should catch
casual errors. The `g_object_ref()` and `g_object_unref()` calls which
subsequently happen inside the `g_set_object()` function also do some
dynamic type checks.

Use the new g_type_interface_instantiable_prerequisite() to check
compatibility for transform functions.
In particular, this allows interfaces (in my case GDK_TYPE_PAINTABLE) to
be transformed to/from any GObject type (in my case G_TYPE_OBJECT) using
the transform function registered to tranform between any 2 objects
(g_value_object_transform_value() does a type check and uses NULL if the
types don't match).
And this in turn allows be to g_object_bind_property() a gobject-typed
generic property (GtkListItem::item) to a GtkImage::paintable.
Use the newly added g_type_interface_instantiable_prerequisite() to
allow closure return values being interfaces by looking up the
instantiable type for the interface and usings its GValue accessors.
There is (at most) a single GType that is instantiable and a
prerequisite for an interface. This function returns that type.
This type is necessary in particular when dealing with GValues because a
GValue contains an instance of a type.
The format has never previously been specified. It can be anything, but

Rather than adding a canonicalised and non-canonicalised version of the
signal to `g_signal_key_bsa`, just add the canonicalised version. Signal
lookups always use the canonicalised key (since the previous commit).
This saves space in `g_signal_key_bsa`, which should speed up lookups;
and it saves significant space in the global `GQuark` table (a 9.6%
reduction in entries in that table, by a rough test using
gnome-software).
We have to be a little more relaxed on the signal name validation than
we are for property name validation, as GTK installs a
`-gtk-private-changed` signal which violates the signal naming rules.

Previously, we’d look up the signal name as passed to (for example)

In preparation for only inserting signals into `g_signal_key_bsa` once,
we now try looking up a signal with the given signal name and, if that
fails, try canonicalising the name and trying again.
This is a performance hit on lookups for non-canonical names, but
shouldn’t affect the performance of lookups for canonical names. If
people want performance, they should use canonical names.

The previous documentation said this:
g_type_add_interface_static:
"Adds the static interface_type to instantiable_type"
g_type_add_interface_dynamic:
"Adds the dynamic interface_type to instantiable_type"
The above suggests that if one is adding a static interface to a dynamic
object, one should use g_type_add_interface_static because the interface
is static, but the code and usage (with the newly added
G_IMPLEMENTS_INTERFACE_DYNAMIC) imply that this is wrong, and that
what matters is whether the *instanciable_type* is dynamic or not.
Hence this patch moves the "static" and "dynamic" words close to
"instantiable_type".

argument with an explicit `true` or `false` value can be removed,
whereas all instances of `install` with a value determined from a

The two test scripts actually assumed some *NIX paradigms, so we need
to adapt them so that they can work on Windows as well, the changes are
namely:
-Call the glib-mkenums and glib-genmarshal Python scripts with the
Python interpreter, not just relying on shebang lines, on Windows.
This is because the native Windows console (cmd.exe) does not support
shebang lines, for subprocess.run().
-Use NamedTemporaryFile with delete=False, otherwise Windows cannot find
the temp files we need when running the tests.
-Use universal_newlines=True for subprocess.run() so that we do not need
to worry out line ending differences on different systems.
-Make sure we are not in the temp directories we create, where the tests
are being run, upon cleanup. Windows does not like deleting
directories that we are currently in.
On Windows and possibly other platforms the '%p' printf modifier does
not prefix printed values with '0x', so do not expect the warning
message to contain the '0x' prefix for the handler pointer value.

Since out-of-source-tree builds are now used after switching to meson,
we don't need .gitignore files in the source directories to ignore

This fixes build errors when doing a meson build after an autotools
build, because generated files such as gio/xdp-dbus.c won't show up in
a `git status`, or be removed by a `git clean -f`, and so it won't be
obvious that such files need to be removed for the meson build to
succeed.
Currently, there is no way to prevent tests from building using meson.
When cross-compiling, building the tests isn't necessary.
Instead, only build the tests on the following conditions:

G_DISABLE_DEPRECATED should never be used by anybody, least of all by
GLib. We have deprecation annotations for the compiler, these days, and
they are much better suited than a macro that makes symbols appear and
disappear. The fact that gtk-doc doesn't understand the deprecation
annotations is a limitation of gtk-doc, and it's gtk-doc that ought to be
fixed.
Commit 80fcb1bc broke GStreamer, which disables old API that was
deprecated before the introduction of the deprecation annotations, but
still uses newly deprecated one, and relies on the deprecation
annotations to do their thing. It also broke libsoup, as it uses
GValueArray in its own API.
This is not new; all of its methods have been deprecated for a long
time. Make the deprecation more obvious, however, by marking the whole
section as deprecated.

Conceptually the binding is kept alive as long as both the source and
target exist. This means that an API user needs to take some care to
either hold a reference or only use a pointer to the binding as long as
also holding references to both objects.
Clarify the documentation a bit.
Turns out the fix in commit 93555577c wasn't enough, when using glib as
subproject and the parent project uses only libgio_dep, and include
<gi18n.h>, it won't find libintl.h because it's in the
include_directories of libglib_dep. Fix that by declaring dependencies
explicitly, which is the right thing to do since glib and gobject are
public dependencies of gio. That reflects what we do for the pkg-config
file as well.
When passing a function to G_IMPLEMENT_INTERFACE, it actually has to
take two arguments. Who knew?

g_object_bind_property() (transfer none) returns a GBinding with an existing internal
reference which is active as long as the "binding" is. This allows to optionally use
the binding without any memory management, as it will remove itself when it is no longer
needed.
There are currently three ways to remove the "binding" and as a result the reference:
1) Either the source or target dies and we get notified by a weakref callback
2) The user unrefs the binding until it is destroyed (which is semi-legal,
but worked and is used in the test suite)
3) The user calls g_binding_unbind()
In case (3) the problem was that it always calls unref even if the "binding" is already
gone, leading to crashes when called from bindings multiple times.
In #1373 and !197 it was noticed that a function always unrefs which would be a
"transfer full" annotation, but the problem here is that it should only remove the
ref when removing the "binding" and the annotation should stay "transfer none".
As a side effect of this fix it is now also possible to call g_binding_unbind() multiple
times where every call after the first is a no-op.
This also adds explicit tests for case (1) and (3) - only case (3) is affected by this change.
Part of runMkenumsWithHeader() was duplicated in test_reproducible(),
and would otherwise need to be duplicated again in upcoming tests. Many
places duplicated decoding stdout/stderr and checking the exit code.
Introduce a named tuple for the returned fields; and factor out writing
a template file to pass with --template.
The new python module, added with 0.46, works with Python 2 and 3 and
allows to pass a path for the interpreter to use, if the need arises.
Previously the meson build set PYTHON, used in the shebang line of
the scripts installed by glib, to the full path of the interpreter.
The new meson module doesn't expose that atm, but we should set it to
a executable name anyway, and not a full path.
Several of our tools are installed and are used by other projects to
generate code. However, there is no 'install' when projects use glib
as a subproject.
We need some way for glib to 'provide' these tools so that when some
project uses glib as a subproject, find_program('glib-mkenums') will
transparently return the glib-mkenums we just built.
Starting from Meson 0.46, this can be done with the
`meson.override_find_program()` function.
As a bonus, the Meson GNOME module will also use these
'overriden'/'provided' programs instead of looking for them in PATH.
PEP8 says that:
"Comparisons to singletons like None should always be done with is or
is not, never the equality operators."
glib uses a mix of "== None" and "is None". This patch changes all
cases to the latter.
The implementation is silently discarding this anyway, and
g_object_unref() is using atomic operations. So this should be safe.
Having this here triggers -Wdiscarded-qualifiers when g_clear_pointer()

Closes: #699
Meson has the ability to classify tests according to "suites", a list of
tags. This is especially useful when we want to run specific sets of
tests — e.g. only GLib's tests — instead of the whole test suite. It
also allows us to classify special tests, like "slow" ones, so that we
can only run them when needed.
In master, it is already possible to build GLib using Visual Studio
using Meson[1] for some time, so we should focus on maintaining only the
Meson build files for building GLib with Visual Studio.
[1]: There are caveats when building with Visual Studio 2008, namely
that one needs to use the mt command to embed the manifests that
are generated with the .exe/DLLs, for all builds, and that in the
case where the compilation hangs on Visual Studio 2008 x64, as a
workaround, should stop the build by terminating all cl.exe tasks
and change the compiler optimization flag from /O2 (full speed) to
/O1 (optimize for size), due to compiler optimization issues.
It's mostly not used anymore and doesn't do what it says it does.
The docs state that it affects GList, GSList, GNode, GMemChunks, GSignal,
GType n_preallocs and GBSearchArray while:
* GList, GSList and GNode use GSlice and are not affected
* GMemChunks is gone
* GType npreallocs is ignored
It also states that it can be used to force the usage of g_malloc/g_free,
which is handled by G_SLICE=always-malloc now.
The only places where it's used is in signal handling through GBSearchArray
and in GValueArray (deprecated). Since it's unlikely that anyone wants to
reduce allocation sizes just for those cases remove the build option.
valgrind.h is a verbatim copy taken from Valgrind project. Previously

The timer tests expect that a small value for sleep does not result in

The -fstack-protector-strong used in many distributions by default has a
rather drastic slowdown of the fast path in generated _get_type()
functions using G_DEFINE_* macros. The amount can vary by architecture,
GCC version, and compiler flags.
To work around this, and ensure a higher probability that our fast-path
will match what we had previously, we need to break out the slow-path
(registering the type) into a secondary function that is not a candidate
for inlining.
This ensures that the common case (type registered, return the GType id)
is the hot path and handled in the prologue of the generated assembly even
when -fstack-protector-strong is enabled.

The Meson build has fallen a bit behind the Autotools one, when it comes
to the internally built tools like glib-mkenums and glib-genmarshals.
We don't need to generate gmarshal.strings any more, and since the
glib-genmarshal tool is now written in Python it can also be used when
cross-compiling, and without indirection, just like we use glib-mkenums.
We can also coalesce various rules into a simple array iteration, with
minimal changes to glib-mkenums, thus making the build a bit more
resilient and without unnecessary duplication.
The old glib-mkenums was more forgiving, and simply ignored any files it
could not find.
We're going to print a warning, as in the future we may want to allow
more strictness.
This is a bit of a hack to maintain some semblance of backward
compatibility with the old, Perl-based glib-mkenums. The old tool had an
implicit ordering on the arguments and templates; each argument was
parsed in order, and all the strings appended. This allowed developers
to write:
glib-mkenums \
--fhead ... \
--template a-template-file.c.in \
--ftail ...
And have the fhead be prepended to the file-head stanza in the template,
as well as the ftail be appended to the file-tail stanza in the
template. Short of throwing away ArgumentParser and going over
sys.argv[] element by element, we can simulate that behaviour by
ensuring some ordering in how we build the template strings:
- the head stanzas are always prepended to the template
- the prod stanzas are always appended to the template
- the tail stanzas are always appended to the template
Within each instance of the command line argument, we append each value
to the array in the order in which it appears on the command line.
This change fixes the libqmi build.
Some of the arguments that affect the generated result in glib-mkenums
can be used multiple times, to avoid embedding unnecessary newlines in
their values.
This change fixes the NetworkManager build.
When using the `--header --body` compatibility mode, we need to emit
things we generally define in the header, such as the aliases for
standard marshallers, and aliases for deprecated tokens.
This fixes dbus-binding-tool, which is using `--header --body` and
deprecated tokens.

Fixes get_type function generation for:
- GMountMountFlags
- GDriveStartFlags
- GResourceLookupFlags
- GSocketMsgFlags
- GTlsDatabaseVerifyFlags
- GTestDBusFlags
which were registered as enum types before, which broke
some unit tests.
Problem is that the flags annotation has no value, so
options.get('flags') would always return None even if
it was present.

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.
