Fixes: #2425
WebKit wants these private key properties to be readable in order to
implement a deserialization function. Currently they are read-only
because at the time GTlsCertificate was originally designed, the plan
was to support PKCS#11-backed private keys: private keys that are stored
on a smartcard, where the private key is completely unreadable. The
design goal was to support both memory-backed and smartcard-backed
private keys with the same GTlsCertificate API, abstracting away the
implementation differences such that code using GTlsCertificate doesn't
need to know the difference.
The original PKCS#11 implementation was never fully baked and at some
point in the past I deleted it all. It has since been replaced with a
new implementation, including a GTlsCertificate:private-key-pkcs11-uri
property, which is readable. So our current API already exposes the
differences between normal private keys and PKCS#11-backed private keys.
The point of making the private-key and private-key-pem properties
write-only was to avoid exposing this difference.
Do we have to make this API function readable? No, because WebKit could
be just as well served if we were to expose serialize and deserialize
functions instead. But WebKit needs to support serializing and
deserializing the non-private portion of GTlsCertificate with older
versions of GLib anyway, so we can do whatever is nicest for GLib. And I
think making this property readable is nicest, since the original design
reason for it to not be readable is now obsolete. The disadvantage to
this approach is that it's now possible for an application to read the
private-key or private-key-pem property, receive NULL, and think "this
certificate must not have a private key," which would be incorrect if
the private-key-pkcs11-uri property is set. That seems like a minor
risk, but it should be documented.
On Unix platforms, wait() and friends yield an integer that encodes
how the process exited. Confusingly, this is usually not the same as
the integer passed to exit() or returned from main(): conceptually it's
an integer encoding of this tagged union:
enum { EXITED, SIGNALLED, ... } tag;
union {
int exit_status; /* if EXITED */
struct {
int terminating_signal;
bool core_dumped;
} terminating_signal; /* if SIGNALLED */
...
} detail;
Meanwhile, on Windows, wait statuses and exit statuses are
interchangeable.
I find that it's clearer what is going on if we are consistent about
referring to the result of wait() as a "wait status", and the value
passed to exit() as an "exit status".
GSubprocess already gets this right: g_subprocess_get_status() returns
the wait status, while g_subprocess_get_exit_status() genuinely returns
the exit status. However, the GSpawn family of APIs has tended to
conflate the two.
Confusingly, g_spawn_check_exit_status() has always checked a wait
status, and it would not be correct to pass an exit status to it; so
let's deprecate it in favour of g_spawn_check_wait_status(), which
does the same thing that g_spawn_check_exit_status() always did.
Code that needs backwards-compatibility with older GLib can use:
#if !GLIB_CHECK_VERSION(2, 69, 0)
#define g_spawn_check_wait_status(x) (g_spawn_check_exit_status (x))
#endif

Confusingly, g_spawn_check_exit_status() takes a wait status, not an
exit status, so passing g_subprocess_get_exit_status() to it is
incorrect (although both encodings happen to use 0 to encode success
and a nonzero value to encode failure, so in practice this probably
had the desired effect).

Following on from the previous commit, some explicit
`g_main_context_wakeup()` calls were missing from the test code which
only uses `GMainContext`.
Add them, and also add some assertions to check that these functions are

The tests in `gdbus-names.c` use a mixture of `GMainLoop` and iterating
a `GMainContext` directly. Some of the helper functions based around the
`OwnNameData` struct use the `loop` `GMainLoop` even when called from
tests like `watch_with_different_context()` which themselves use
`GMainContext` directly.
Thus, it’s possible for the `GMainLoop` to not be running, while the
test is iterating on `g_main_context_iteration()`. In this case,
`g_main_loop_quit()` is a no-op and will not wake up the `GMainContext`.
This causes the test to livelock in around 1 in 1200 test runs.
Fix this by adding an explicit `g_main_context_wakeup()` call after each
`g_main_loop_quit()` call. A more comprehensive fix would be to port all
the tests in this file to iterating `GMainContext` directly, and drop
all the `GMainLoop` usage, but I don’t have time for that right now.

If `g_file_monitor_source_dispatch()` drops the last reference to its
`GLocalFileMonitor`, a deadlock will occur, because disposing the
`GLocalFileMonitor` causes synchronous disposal of the
`GFileMonitorSource`, and hence an attempt to re-lock the already-locked
mutex in the `GFileMonitorSource`.
Fix that by dropping the reference to the `GLocalFileMonitor` after
unlocking.

Since commit ab285899a6 ('gdbusconnection: Document main context
iteration for unsubscript'), we document when the user is guaranteed
that all resources are gone after g_dbus_connection_signal_unsubscribe().
This is not merely an implementation detail, it's something that the
user needs to be able to rely on. It is good that this is documented.
However, libnm does something different ([1]). It registers to several D-Bus
signals without providing a GDestroyNotify. After unsubscription, it schedules
another idle action with lower priority and uses that to know when
cleanup is complete. I think this is a useful alternative and should
also be guaranteed and documented to work.
Also note that this isn't just some implementation detail that currently
happens to work. GDBusConnection tightly integrates with GMainContext and it
works by scheduling idle sources with G_PRIORITY_DEFAULT priority. It needs to
schedule all events with this same priority, otherwise the ordering is not
preserved. At this point, with GDBusConnection working this way, this is no longer
something that can reasonably be any different. It's how GDBusConnection fundamentally
works, and a user must be able to rely on that. As such, this new promise isn't
something that we would want to break in the future.
Thus document it.

An application that has been shut down is still marked as registered
even if its implementation has been already destroyed.
This may lead to unguarded crashes when calling functions that have
assumptions for being used with registered applications.
So, when an application is registered, mark it as unregistered just
before destroying its implementation and after being shut down, so that
we follow the registration process in reversed order.

If this g_return_val_if_fail() is ever hit, then we leak arguments.
This is not very important because if your code hits
g_return_val_if_fail() you are invoking undefined behavior, a rather
more serious problem, but let's replace it with g_critical() to be
robust.
This includes a small behavior change: it returns 1 rather than 0 in
this error case.
Found by Coverity.
This function can cause significant delays when the mounted volume
is disconnected or just weird. Use IExtractIconW::GetIconLocation()
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.

The variable `gconstructor_code` (which is what’s defined by
`gconstructor_as_data_h`) is not used at all inside

This looks like a copy/paste error from the build definition for
`glib-compile-resources` below, which does need it.

In the 2.68 cycle we’d added 3 new enumerator elements. Due to the
preceding commit, they can now be annotated with
`GLIB_AVAILABLE_ENUMERATOR_IN_2_68`, which will make it a bit easier for
third party projects to notice when they’re using these symbols without
having bumped their GLib dependency.

`""` is not a valid path (`stat()` on it returns `ENOENT`). Previously,
a full `GLocalFile` was being created, which ended up resolving to
`$CWD`, through path canonicalisation. That isn’t right.
Fix it by creating a `GDummyFile` instead, and adding a unit test.

Calling `dlopen()` with `libutil.so` makes the installed tests depend on
having glibc's development files installed. To avoid this, we can work
out the runtime library name at build time and `dlopen` that instead.
This approach is [taken from libfprint][1], thanks to Marco Trevisan.

`ENXIO` can be returned from `open(2)` for special files (FIFOs, device
files and domain sockets) which are not backed by anything.
This fixes the error returned by `g_file_replace()` when trying to
replace such a file, so that it now matches the documentation.

These test all the functionality and combinations of flags I can think
of. They do not cover dynamic behaviour (for example, what would happen
if the source file is deleted by another process part-way through a call
to `g_file_replace()`).

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),
data-to-c.py embedded that line endings into generated string literal. And
then they translated to double newlines in glib-compile-resources output.
clang-cl failed to compile such files because of empty lines in the middle of
multiline macros:
#define G_MSVC_CTOR(_func,_sym_prefix) \
static void _func(void); \
To fix the issue, enable 'universal newlines' mode when reading the input in
data-to-c.py - translate both '\n' and '\r\n' to '\n'.

This will require distributions to ensure they pass
`--localstatedir=/var` correctly to Meson, but they should be doing that
already.

It’s unlikely that the machine ID will be invalid (it’s system
configuration), but it would be helpful to not propagate invalid IDs
further, since a lot of things rely on it.
It’s not easy to test this (it requires factoring out the code so it can
be used from a test program, or allowing it to load a machine ID from a
custom path), so I haven’t added unit tests. I’ve tested manually by
overriding the loaded machine ID.

For non-Linux UNIX systems, the label 'close_libutil:' in
'test_pollable_unix_pty()' will have no statement that goes with that
label. Just do a 'return' on non-Linux UNIX systems.
File monitor creation may fail. We should check for this, rather than
ignoring it and then spewing criticals upon improperly assuming that we
have a valid GFileMonitor rather than NULL.
In practice, creating the GFileMonitors here fail when opening a large
number of tabs in Epiphany. I'm still investigating to see why, but it
doesn't matter for the purposes of this commit.
Expand an existing unit test to check that the target FD of a
`g_subprocess_launcher_take_fd()` call doesn’t get closed when
`g_subprocess_launcher_close()` is called. Only the source FD should be

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).
Thanks to Olivier Fourdan for the detailed bug report.

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.
