Avoid generating more code than needed, so other than continuing using
the generic glib marshallers when possible, define once the custom ones
we need for each file we generate.
The marshallers are then re-used across all the interfaces defined
without duplicating the code size.
This is the same we're doing in code generated by glib-genmarshaller and
what gmarshal does internally.
Since the generated gdbus C code can be considered private too, this is
safe to do, and will allow faster access to GValue objects.
Get rid completely of the usage of the generic marshaller in gdbus
generated code, using instead specific marshallers.
Code is not yet optimized fully since we may still have duplicated
functions to be generated.
Closes: https://gitlab.gnome.org/GNOME/glib/-/issues/3028
We relied on g_cclosure_marshal_generic() to easily generate signal
marshallers, but this relies on inspecting each parameter type with ffi
and this implies a performance hit, other than breaking the stack-frame
unwinder used by Linux perf and so by sysprof.
Given that we know the types we work on, it's easy enough to generate
the marshallers ourself.

We were using emit_by_name which implies looking up for the signal name,
while the generated code can easily remember the signal ID and use it
instead, allowing direct access to the signal emission.
glib-compile-resources --dependency-file= currently generates a depfile
with rules that look like this:
foo.xml: resource1 resource2
This means that if any of the files listed in the GResource manifest
foo.xml change, rebuild foo.xml because foo.xml depends on those files.
This is not useful because the XML manifest is not expected to be a
generated dependency and even if it was, changes to the listed files
would not imply any need to regenerate the manifest. What we really do
need to regenerate is the C source file that is generated by
glib-compile-resources after processing the XML manifest and all the
resource files. That is, the rule should look like this:
foo.c: foo.xml resource1 resource2
as suggested by Hans Ulrich Niedermann in the issue report.
Fixes#2829
Currently we require explicitly specifying the port when configuring a
proxy server, which is seriously weird. I take the fact that nobody
reported a bug until 2022 to indicate that almost nobody is using
proxies. Whatever. Let's assume that if no port is provided, the default
port for the protocol should be used instead.
For example, you can now specify in GNOME settings that your proxy server
is https://example.com and it will work. Previously, you had to write
https://example.com:443. Yuck!
This was originally reported as GProxyResolver bug, but nothing is
actually wrong there. It's actually GProxyAddressEnumerator that gets
tripped up by URLs returned by GProxyResolver without a default port.
This breaks GSocketClient.
Fixing this requires exposing GUri's _default_scheme_port() function to
GIO. I considered copy/pasting it since it's not very much code, but I
figure the private call mechanism is probably not too expensive, and I
don't like code duplication.
Fixes#2832
On some platforms, pointer-sized reads are not necessarily atomic, so we
always need to use the correct atomic access primitives.

When the gnome test runner executes the tests, the test appear to execute in disk
order. This means it sometimes works and sometimes we see breakage in portal-support-snap
and portal-support-snap-classic.
The issue is that some tests create config files but some don't. If they run
in the wrong order, tests see config files they shouldn't and break.
Fix this by deleting the files after each test run, properly cleaning up after
themselves. The cleanup code is based upon gtestutils.c:rm_rf().

Since we have a convenience method to add actions let's allow to remove
them just as easily. This makes resource cleanup as simple as initially
adding the entries.
Makes the tests compile using clang with meson directly under
termux on android, this build environment does not approve of
overloading libc symbols.
Fixes: #3008
foo
This is a workaround for build conditions one ends up with under termux,
where the defined __ANDROID_API__ level is lower than what is provided
by gcc installed for it, the libc .so nevertheless contains these symbols
thus enabling the codepaths. This definition is only in use when meson
detected the presence of this symbol in the libc.
Fixes#3008
foo
In the typical `while (g_file_enumerator_next_file ())` patterns,
there is nothing much checking whether the operation was cancelled
on the GIO side. Unless the user checks for the case, this means
local enumerators always run to completion even if cancelled.
Fix this by checking the cancellable state explicitly for local
enumerators, so there are oportunities for bailing out early if
the enumerator is going through a very large directory.
Note that the prepare callback only has one caller, which pre-initializes
the timeout argument to -1. That may be an implementation detail and not
publicly promised, but it wouldn't make sense to do it any other way in
the caller.
Also, note that g_unix_signal_watch_prepare() and the UNIX branch of
g_child_watch_prepare() already relied on that.
When `copy_file_range()` support was added, I used the definition of
`copy_file_range()` from Linux, which uses `loff_t` to abstract the
different `off*_t` types.
`loff_t` doesn’t exist on FreeBSD, so this doesn’t compile, and was
caught in subsequent asynchronous CI.
Define `loff_t` with a fallback value if it’s not defined, which should
fix this and other uses of `loff_t` in `gfile.c` (for example, if
FreeBSD ever starts declaring `splice()`).

GTK lost it's '+' suffix back in 2019, according to
<https://mail.gnome.org/archives/gtk-devel-list/2019-February/msg00000.html>
This commit can be re-generated with:
git grep -l GTK+ \
| grep -v -e ^NEWS -e ^glib/tests/collate.c \
| xargs sed -i 's/GTK+/GTK/g'
Most of the changes are in comments and documentation.
While it can’t be used in all situations, it is a little bit faster than
`splice()` in some situations, basically if the file system supports
copy on write. In other situations it’s no slower than `splice()`.
See `man copy_file_range` for the situations where it doesn’t work. In
all of these situations, it will return an error, and the GLib code will
fall through and try the existing `splice()` copy code instead.
From my testing of `time gio copy A B` with a 9GB file, the `splice()`
code path takes 22s, and the `copy_file_range()` code path takes 20s.

Fixes: #2863
The start of the `g_file_copy()` implementation stats the source file to
find all the attributes to copy onto the destination file, so it makes
sense to get it to store the source file size at the same time.
This saves a subsequent `stat()` call on the source FD in the btrfs
reflink or splice code. Every little helps.

Something has changed recently which causes this error to now be emitted
when building on Windows msys2-mingw32:
```
../gio/gwin32networkmonitor.c: In function 'win_network_monitor_get_ip_info':
../gio/gwin32networkmonitor.c:92:15: error: storing the address of local variable 'prefix' in '*dest' [-Werror=dangling-pointer=]
92 | *dest = (guint8 *) &prefix.Prefix.Ipv4.sin_addr;
| ~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
If `IP_ADDRESS_PREFIX` is defined as a scalar rather than a pointer,
that could explain the problem.
Change the function to always operate on a pointer to avoid any
potential such issues.
