It may be defined by the environment (we document that as being allowed)
— if so, individual files should not try to redefine it, as that causes
a preprocessor warning.

In ostree based systems, such as flatpak and fedora silverblue, the
time of modification of every system file is epoch 0, including
giomodule.cache, which means that every module is loaded and unloaded
every time.
The solution is to use the change time of the file as well. In a typical
system, it is equal to the mtime, and in an ostree based system, since
the directory is mounted as read-only, the user cannot add a module and
we must assume that the cache file corresponds to the modules.
This was mostly machine generated with the following command:
```
codespell \
--builtin clear,rare,usage \
--skip './po/*' --skip './.git/*' --skip './NEWS*' \
--write-changes .
```
using the latest git version of `codespell` as per [these
instructions](https://github.com/codespell-project/codespell#user-content-updating).
Then I manually checked each change using `git add -p`, made a few
manual fixups and dropped a load of incorrect changes.
There are still some outdated or loaded terms used in GLib, mostly to do
with git branch terminology. They will need to be changed later as part
of a wider migration of git terminology.
If I’ve missed anything, please file an issue!

It could've never been uninitialized in this code but the code flow is
not obvious to the compiler. Initialize it to NULL and for clarity also
add an assertion that it is not NULL anymore on usage.

Interpret the value "help" for environment variables that
are passed to _g_io_module_get_default(), and print the
names and priorities of available extensions.
This lets users explore what is available, and can be helpful
in figuring out why a certain extension was chosen as default.
It is similar in spirit to what we already do with environment
variables like G_DEBUG.
This is useful for debugging in many situations. It’ll be printed with
G_MESSAGES_DEBUG=GLib-GIO or G_MESSAGES_DEBUG=all.
Mostly I need it for debugging the default GNetworkMonitor, but it will
work for all GIO module implementations.

This adds a null notification backend implementation for win32, purely
to avoid crashes due to a missing backend when applications use
GNotification. This backend does nothing except print a warning when a
notification is supposed to be emitted.
In future, it can be expanded to use win32 API to present toaster
notifications appropriately.

Added a Windows backend to GNetworkMonitor, using NotifyRouteChange2()
(available on Vista and later). It marshals the route change callbacks
to the thread-specific default main context the GNetworkMonitor was
constructed in.

GIO modules should include their name into their exported symbols to
make them unique. This avoids symbol clash when building modules
statically.
extract_name() function is copied from GStreamer which recently
switched to the same symbol naming scheme.

Where we were already treating GHashTables as sets, modify them to use
the set-specific APIs g_hash_table_add() and g_hash_table_contains(), to
make that usage more obvious and less prone to being broken.

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 an implementation of most of GAppInfo using the OS X
NSBundle APIs.
Missing at this point are things that don't have equivalents
in OS X, such as hidden desktop files, last-used, manual type
associations, and g_app_info_get_all().

When unregistered extension point (i.e. NULL pointer) is passed
to `g_io_extension_point_get_extensions`, it causes a segfault.
This commit adds an assertion, to prevent this.

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.
xdg-desktop-portal support is only usable on *NIX platforms, so don't build
them on non-*NIX platforms. Also clean up gio/Makefile.am a bit to split out
the listings for the platform-specific sources from the platform-neutral
sources, and assemble them for the final list of sources required for libgio.

The backend for this lives in xdg-desktop-portal,
and is in turn using GNetworkMonitor.
When network is not available in the sandbox, there is
no point in reporting accurately about the network
status outside the sandbox. Just return 'no connection'
in this case.

Remove all event merging and dispatch logic from GFileMonitor. The only
implementation of GFileMonitor outside of glib is in gvfs and it already
does these things properly.
Get rid of GLocalDirectoryMonitor. We will use a single class,
GLocalFileMonitor, for both directory and file monitoring. This will
prevent every single backend from having to create two objects
separately (eg: ginotifydirectorymonitor.c and ginotifyfilemonitor.c).
Introduce GFileMonitorSource as a thread-safe cross-context dispatch
mechanism. Put it in GLocalFileMonitor. All backends will be expected
to dispatch via the source and not touch the GFileMonitor object at all
from the worker thread.
Remove all construct properties from GLocalFileMonitor and remove the
"context" construct property from GFileMonitor. All backends must now
get the information about what file to monitor from the ->start() call
which is mandatory to implement.
Remove the implementation of rate limiting in GFileMonitor and add an
implementation in GLocalFileMonitor. gvfs never did anything with this
anyway, but if it wanted to, it would have to implement it for itself.
This was done in order to get the rate_limit field into the
GFileMonitorSource so that it could be safely accessed from the worker
thread.
Expose g_local_file_is_remote() internally for NFS detection.
With the "is_remote" functionality exposed, we can now move all
functions for creating local file monitors to a proper location in
glocalfilemonitor.c
Port the inotify backend to adjust to the changes above. None of the
other backends are ported yet. Those will come in future commits.
Availability of the g_nextstep_settings_backend_get_type() prototype
is controlled by HAVE_COCOA in gsettingsbackendinternal.h and the
actual implemenation by OS_COCOA in Makefile.am. Therefore, the
giomodule.c call to that function should also be protected by a COCOA
token rather than an CARBON token (cocoa and carbon are independent
autoconf tests).

Since we are no longer using sgml mode, using /* */ to
escape block comments inside examples does not work anymore.

Our check for inotify_init1() being defined is broken. We happily
declare that inotify is supported, even if the check fails.
This was originally intended to check for inotify_init1 in the libc so
that we could fall back to inotify_init if it was not yet defined.
FreeBSD has a libinotify that emulates the inotify API via kqueue. It
installs a <sys/inotify.h> header and requires linking to -linotify. We
don't want to falsely detect working inotify in this case.
Treat the lack of inotify_init1() in the libc as a lack of inotify
support. This requires only a new libc -- we still support old kernels:
in the case that inotify1_init() fails, we fall back to inotify_init().
