This function can cause significant delays when the mounted volume

instead.
Theoretically, this should require COM to be initialized, but in my tests
this code worked just fine without calling CoInitializeEx().
On Windows gio runs a thread to update appinfo at startup.
If someone unloads gio (this happens when a dynamic gio module gets
unloaded by a program that doesn't use gio itself), there doesn't seem
to be a way to detect that until gio is already gone, and as soon as
gio is gone, the thread crashes, since it tries to execute instructions
that are no longer there.
Holding an extra reference to gio DLL fixes this, but it also prevents
gio from being unloaded, and there's no "weak references" for DLLs.
So we just pin gio and acknowledge that it will never be unloaded.

After the recent reworking of this code it was possible for `g_close()`
to be called on `fd == -1`, which is invalid. It would have reported an
error, were errors not ignored. So it was harmless, but still best to
fix.
Simplify the error handling by combining both error labels and checking
the state of `fd` dynamically.

Calling `dlopen()` with `libutil.so` makes the installed tests depend on

The `G_FILE_CREATE_REPLACE_DESTINATION` flag is equivalent to unlinking
the destination file and re-creating it from scratch. That did
previously work, but in the process the code would call `open(O_CREAT)`
on the file. If the file was a dangling symlink, this would create the
destination file (empty). That’s not an intended side-effect, and has
security implications if the symlink is controlled by a lower-privileged
process.
Fix that by not opening the destination file if it’s a symlink, and
adjusting the rest of the code to cope with
- the fact that `fd == -1` is not an error iff `is_symlink` is true,
- and that `original_stat` will contain the `lstat()` results for the
symlink now, rather than the `stat()` results for its target (again,
iff `is_symlink` is true).
This means that the target of the dangling symlink is no longer created,
which was the bug. The symlink itself continues to be replaced (as
before) with the new file — this is the intended behaviour of
`g_file_replace()`.
The behaviour for non-symlink cases, or cases where the symlink was not
dangling, should be unchanged.
Includes a unit test.

When GLib code is checked out with Windows line endings (happens on Windows),

This is a regression introduced in commit 67a589e505. Previously, the
source/target FD pairs were stored in `needdup_fd_assignments`, in
consecutive entries, so source FDs had even indices and target FDs had
odd indices.
I didn’t notice that the array index was being incremented by 2 when
closing FDs, when porting from the old code. So previously the code was
only closing the source FDs; after the port, it was closing source and
target FDs.
That’s incorrect, as the target FDs are just integers in the parent
process. It’s only in the child process where they are actually FDs —
and `g_subprocess_launcher_close()` is never called in the child
process.
This resulted in some strange misbehaviours in any process which used
`g_subprocess_launcher_take_fd()` with target FDs which could have
possibly aliased with other FDs in the parent process (and which weren’t
equal to their mapped source FDs).

This was correctly annotated for proper return values but in case of out
parameters it was only annotated as (optional) and not additionally as
(nullable).
This improves performance by eliminating the use of a
`GSpawnChildSetupFunc` in the common case (since that setup code has now
moved into `g_spawn*()` itself), and enables the use of the fix to avoid
the child error reporting FD being overwritten by target FD mappings,
introduced via `g_spawn_async_with_pipes_and_fds()`.
It reworks how the source/target FD mapping is stored within
`GSubprocessLauncher` to match what `g_spawn*()` uses. The two
approaches are equivalent.

`GTestDBus` is de-facto deprecated and so putting any more effort in is
a waste.
This fixes an issue where a test would print duplicate output when
outputting to a fully-buffered FD, such as a pipe. This is because the
buffer is non-empty before the `fork()`, and ends up duplicated in the
parent and child processes, both of which later flush the duplicated

It’s not feasible to test that the require-same-user flag can cause

`$prefix/gdbus-daemon --print-env &`
gdbus call --session --dest org.freedesktop.DBus --object-path /org/freedesktop/DBus --method org.freedesktop.DBus.ListNames
```
And then running the `gdbus call` command again as user B (with the same
value for `DBUS_SESSION_BUS_ADDRESS` in the environment), which
produces:
```
Error connecting: Unexpected lack of content trying to read a line
```
(an authentication rejection)

but only return the one corresponding to the last byte-order to the

Where the early call to g_socket_set_option() fails because of
check_socket() failing due to `inited` still being FALSE.
This brings 634b692 back into working order, by fixing the regression
introduced in 39f047e.

Split out XDG_CURRENT_DESKTOP handling to a separate function and make
sure that it drops all the invalid entries properly. Earlier a bad
entry could slip through the checks by sitting just after another bad
entry, like in env being set to `invalid1!:invalid2!`, where
`invalid2!` could slip the checks.

- When querying a TCP socket, getsockopt() may succeed but the resulting
`optlen` will be zero. This means we'd previously be reading
uninitialized stack memory in such cases.
- After a file-descriptor has gone through FD-passing, getsockopt() may
fail with EINVAL. At least this is the case with TCP sockets.
- While at it also use SOL_LOCAL instead of hard-coding its value.
Contrary to what the WSARecvFrom seem to imply, a UDP socket is perfectly recoverable and usable after a WSAECONNRESET error (and, I assume, WSAENETRESET).
However GSocket condition has the FD_READ bit set after a UDP socket fails with WSAECONNRESET, even if no data is available on the socket anymore; this causes select calls to report the socket as readable when, in fact, it's not.
The change resets FD_READ flag on a socket upon the above error conditions; there's no 'if' to filter between datagram and stream sockets as the change should be harmless in the case of stream sockets which are, however, very unlikely to be usable after a WSAECONNRESET.
The list is sorted in ascending order, which means that to put
verbs alphabetically we need to sort ealier verbs with -1. Same for
the "open" verb and the preferred verb (if any).
* UWP apps that have low registry footprint might end up with chosen_handler == NULL.
Ensure that this doesn't happen.
* UWP apps don't need verbs for URIs, but we do need verbs to have a link to an app
(since handlers don't contain app fields). Work around this by adding an "open" verb
to each UWP URI handler.
* Duplicate the code that inserts extension handler verbs into the app to also insert
URI handler verbs. This allows URI-only apps to be used correctly later on (otherwise
GLib errors out, saying that the app has no verbs).
Use pretty name as the result of _name(), if available. This is
more in line with what .desktop files return. Canonical name
may be completely unintelligible.
MSDN doesn't say much on this subject, but i've seen apps in the wild
that have the "shell" subkey with verbs *either* in the root app key *or*
in the "Capabilities" subkey of the root key. Accommodate either case by trying both
(root key gets a priority, since this is how MS Address Book is registered -
assume that MS knows how to do this the right way).
This function enumerates all user-accessible UWP packages
and calls the user-provided callback for each package.
This can be used to make GLib aware of the UWP applications
installed in the system.
The function works by using IPackageManager/IPackage UWP interfaces
and XmlLite COM library to parse package manifests.
The function requires COM, and initializes it to a single-thread
appartment model. To ensure this doesn't break anything, either
only use it in a separate thread (COM is initialized on a per-thread
basis), or make sure that the main thread also uses the same COM
model (it's OK to initialize COM multiple times, as long as the same
model is used and as long as init/uninit calls are paired correctly).
MinGW-w64 lacks the appropriate headers, so we have to add them
here. Note that these only have the C versions (normally these
things come in both C and C++ flavours), since that's what we use.
Also note that some of the functions that we don't use (but must
describe to maintain binary compatibility) were altered to use
IUnknown (basically, an untyped pointer) instead of the appropriate
object types, as adding these types would require other types,
which would pull even more types, forcing us to drag half of the
UWP headers in here. By replacing unused types with IUnknown we
can trim a lot of branches from the dependency graph.
This is a COM object that implements IStream by using a HANDLE
and WinAPI file functions to access the file (only a file; pipes
are not supported). Only supports synchronous access (this is
a feature - the APIs that read from this stream internally will
never return the COM equivalent of EWOULDBLOCK, which greatly
simplifies their use).
Just embed a PNG instead. gdk-pixbuf deprecated its pixdata support in
version 2.32, in 2015.
