This is useful when writing similarly low-level code, and was always true
as implemented here; let's document it so that other codebases can rely
on it.

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
This is true for socks://, socks4://, socks4a://, and socks5://. I could
list them individually and risk breaking in the future if socks6:// ever
exists, or test for "socks" and risk breaking if a future URL scheme
begins with "socks" but doesn't use port 1080. I picked the latter.
The compiler annotations are mainly useful for people using the symbols
directly.
To avoid getting compiler warnings for the GTypeValueTable definition
itself, we need to wrap the structure with
G_GNUC_BEGIN_IGNORE_DEPRECATIONS and G_GNUC_END_IGNORE_DEPRECATIONS.
The introspection scanner cannot deal very well with function pointers
into a plain structure. In order to document the various function
pointers in GTypeValueTable we need to create typed callbacks, and
use them to replace the anonymous function pointers inside the
structure. This not only allows us to properly document the function
pointers, but it also allows us to annotate the arguments and return
value of those function pointers.

For now, the function parse_trigraph() defined in gobject/glib-mkenums
script was not taking double-quotes characters into account:
>>> parse_trigraph('name="eek, a comma"')
{'name': '"eek', 'a': None}
This patch take double-quotes characters into account:
>>> parse_trigraph('name="eek, a comma"')
{'name': 'eek, a comma'}
Closes issue #65
Normally we don't really have emission hooks around, so try to allocate
only tiny array to contain a few of them and in case we exceed that limit,
we go back to use allocated ones.
We used to call this function as unlocked, with a node value that
could be invalid at the point of the call, so let's ensure that when
we call such function it's defined, and then reduce the access to the
signal node members when we're unlocked or after a lock/unlock operation
that may have changed it.
As per this, add more tests handling multiple signal hooks cases that we
did not cover before.
In g_signal_emit_valist() we used to access to param types array and
n_params values after unlocking the mutex, and this might have lead to
making such values unreliable for the current call.
So let's keep them around until we're done with the function call
Since we're locking and unlocking once we've found the signal ID, we
might have performed calls to g_signal_emit_valist() with a signal id
that was already been removed, and thus failing later.
This is not really an issue as inside g_signal_emit_valist() we were
re-checking for the signal id, but we can make this more reliable so
that the first thread that acquires the lock can also be sure to emit.
This allows the `g_free()` wrapper introduced in the previous commit to
only be defined if `free_sized()` is actually available to improve
performance.
This avoids passing an allocation size to every `g_free()` call if it’s
not going to be used, saving a register store instruction each time.

When using GCC we can take the advantage of __builtin_object_size() to
know the allocated size of a memory area, this generally only works when
some optimization level enabled (-O1 seems enough here) and can provide
us with memory size information for lower-level optimizations.
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.
Adds a helper to truncate UTF8 strings in the middle, allowing to make
them fit certain size constraints.
This function is modeled after similar functionality that has existed
since 2008 in nautilus and in eel before that.
If people do that, it clutters the place up with branches which are not
deleted-on-merge by default. Better to use their own forks.
And the people who are in a position to be able to push directly to
`origin` are not going to be reading the `CONTRIBUTING.md` file, so this
paragraph is noise to most readers anyway.

GLib can’t grow forever, so we should really only be accepting APIs
which are useful across a variety of projects and which couldn’t easily
live in a separate library.

Point strongly towards `SECURITY.md` so we are not maintaining security

It’s a bit confusing to have two files called `README`, especially given
that `README.win32.md` only contains build instructions and none of the
other overview/contribution/bug reporting information that `README.md`
contains.
It feels like these would be better organised by having one top-level
`README.md`, and pointing to the Windows build instructions from there.
