g_date_time_add_seconds() and g_date_time_add_full() use floating-point
seconds, which can result in the value varying slightly from what's
actually on disk. This causes intermittent test failures in
gio/tests/g-file-info.c on Debian i386, where we set a file's mtime
to be 50µs later, then read it back and sometimes find that it is only
49µs later than the previous value.
I've only seen this happen on i386, which means it might be to do with
different floating-point rounding when a value is stored in the 80-bit
legacy floating point registers rather than in double precision.
g_date_time_add() takes a GTimeSpan, which is in microseconds;
conveniently, that's exactly what we get from the GFileInfo.

As with the previous commit, `st_mode` contains both the file type

When compiling GLib with `-Wsign-conversion`, we get various warnings
about the atomic calls. A lot of these were fixed by
3ad375a629, but some remain. Fix them by
adding appropriate casts at the call sites.
Note that `g_atomic_int_{and,or,xor}()` actually all operate on `guint`s
rather than `gint`s (which is what the rest of the `g_atomic_int_*()`
functions operate on). I can’t find any written reasoning for this, but
assume that it’s because signedness is irrelevant when you’re using an
integer as a bit field. It’s unfortunate that they’re named a
`g_atomic_int_*()` rather than `g_atomic_uint_*()` functions.
Tested by compiling GLib as:
```
CFLAGS=-Wsign-conversion jhbuild make -ac |& grep atomic
```
I’m not going to add `-Wsign-conversion` to the set of default warnings
for building GLib, because it mostly produces false positives throughout

Previously, if a method was not annotated with org.gtk.GDBus.C.UnixFD
then the generated code would never contain GUnixFDList parameters, even
if the method has 'h' (file descriptor) parameters. However, in this
case, the generated code is essentially useless: the method cannot be
called or handled except in degenerate cases where the file descriptors
are missing or ignored.
Check the argument types for 'h', and if present, generate code as if
org.gtk.GDBus.C.UnixFD annotation were specified.
This change will break any existing code which refers to the (useless)
wrappers for such methods. The workaround for such code is to add the
org.gtk.GDBus.C.UnixFD annotation, which will cause the same generated
code to be emitted before and after this change.
If this is found to cause widespread problems, we can explore a
different approach (perhaps emitting a warning from the code generator,
or annotating the symbols as deprecated).

The gobject introspection comments have a reference to an incorrect
class: they have, as 'self', the GSubprocess class instead of
GSubprocessLauncher.
This patch fixes this.
g_settings_backend_watch() uses a weak notify for keeping track of
the target. There's an explanation why this is supposed to be safe but
that explanation is wrong.
The following could happen before:
1. We have the target stored in the watch list
2. The last reference to the target is dropped in thread A and we end up
in g_settings_backend_watch_weak_notify() right before the mutex
3. g_settings_backend_dispatch_signal() is called from another thread B
and gets the mutex before 2.
4. g_weak_ref_init() is called on the target from thread B, which at
this point has a reference count of exactly one (see g_object_unref()
where it calls the weak notifies)
5. Thread A continues at 3. and drops the last reference and destroys
the object. Now the GWeakRef from 4. points to a destroyed object. Note
that GWeakRefs would be cleared before the weak notifies are called
6. At some later point another thread g_weak_ref_get() is called by
g_settings_backend_invoke_closure() and accesses an already destroyed
object with refcount 0 from the GWeakRef created in 4. by thread B (or
worse, already freed memory that was reused).
Solve this by actually storing a GWeakRef of the target in the watch
list and only access the target behind it via the GWeakRef API, and then
pass a strong reference to the notification dispatch code.
The weak notify is only used to remove the (potentially with empty
GWeakRef) target from the list of watches and the only place that
compares the target by pointer instead of going through the GWeakRef
API.

We're using the `install` argument for configure_file() all over the
place.
The support for an `install` argument for configure_file() was added in
Meson 0.50, but we haven't bumped the minimum version of Meson we
require, yet; which means we're getting compatibility warnings when
using recent versions of Meson, and undefined behaviour when using older
versions.
The configure_file() object defaults to `install: false`, unless an
install directory is used. This means that all instances of an `install`
argument with an explicit `true` or `false` value can be removed,
whereas all instances of `install` with a value determined from a
configuration option must be turned into an explicit conditional.
The comment previously said ‘never %NULL’, but it wasn’t clear whether
this meant `(not nullable)` or `(not optional)`. From looking at the

2. Stop adding the 'dconf hole' to the sandbox
To keep us from switching to the keyfile backend
prematurely, look at whether the app has stopped

We need to also do this for the following, for similar reasoning:

-Dependency discovery without pkg-config files
-long long and ssize_t detection
We do, however, enable the autoptr tests for clang-cl builds. Note that
at this point real MSVC builds are still better supported than clang-cl
builds, and it will likely remain so for at least the near future,
alhtough real MSVC builds of the GTK stack are consumable and are usable

In _g_object_unref_and_wait_weak_notify() we take a weak reference and
then call g_object_unref() in an idle callback, which may look like
we're dropping a strong reference without having one. So change the
comment to make it more clear that the reference being dropped is held
by the caller.
Now that we're not calling g_object_run_dispose() indirectly in
g_test_dbus_down() (see commit "Revert "gtestdbus: Properly close server
connections""), the test gdbus-connection-loss is failing with the
message "Bail out! GLib-GIO-FATAL-WARNING: Weak notify timeout, object
ref_count=1". This is because we're holding a reference to the singleton
connection object while calling session_bus_down() in the test's main().
So then we end up waiting for 30 seconds in
_g_object_unref_and_wait_weak_notify() for the GWeakNotify to be
triggered, which never happens.
The fix is to unref the connection before calling session_bus_down().
This is consistent with how other tests work, and is safe because the
only method called on the connection has already errored out, as
asserted by the test.
This reverts commit c37cd19fee.
Now that we've reverted the commit "gtestdbus: Properly close server
connections", g_test_dbus_down() no longer returns early and we no
longer need this workaround. Since the gdbus-names test seems to
properly unref its GDBusConnection objects it's not clear to me why it
needed the sleep to succeed. However even at the time the failure wasn't
reproducible according to this comment[1] so it's probably not worth
spending more effort trying to reproduce it now.

This reverts commit baf92d09d6.
Closes#787
According to the original commit, this change was made because otherwise
g_test_dbus_down() following a g_test_dbus_stop() hangs until it times
out. The timeout being referred to is the 30 seconds which are waited by
_g_object_unref_and_wait_weak_notify() for the GWeakNotify to be
triggered when the last strong reference to the singleton
GDBusConnection object is dropped. But the patch was not correct and the
leak should have instead been fixed by having the last strong reference
holder drop their reference on the GDBusConnection before calling
g_test_dbus_down(). Timing out after 30 seconds is the desired behavior
in the case where someone holds a reference to the singleton for that
entire period.
There are a few problems with this patch. First, as pointed out here[1],
calling g_object_run_dispose() in the idle callback means we are causing
the GWeakNotify to trigger ~immediately rather than waiting 30 seconds
to give another owner a chance to unref. Second, since someone else may
still hold a reference on the object being disposed, they may call
methods on it after it's been disposed which can seg fault as documented
here[2] and as I also saw recently in another project.
It's unclear what the original leak being fixed was, but many have been
fixed between 2013 and now. I ran all the unit tests under valgrind, and
some do fail (some consistently and some intermittently) but none of the
failures seem to only happen after this reversion commit. I also
couldn't find anywhere in the valgrind output where any GDBusConnection
objects are definitely being lost.

This commit changes a comment in _g_dbus_worker_do_read_cb() to be
slightly more useful. At least in my experience debugging an
intermittent unit test failure in another project, this failure
condition occurred because although g_test_dbus_down() ensures that the
session GDBusConnection has exit-on-close set to FALSE before killing
its dbus-daemon, there was still a GDBusConnection on the system bus
which hit this failed read code path, because we had
DBUS_SYSTEM_BUS_ADDRESS set to the address of the #GTestDBus daemon, to
appease libudisks.
Also, make a few other minor improvements to the docs.
On Visual Studio, Meson builds modules as xxxx.dll, not libxxxx.dll when
xxxx is specified as the name for the shared_module() build directive.
This means that in the test programs if we expect for libxxxx for the
module name, the test will fail as there is no libxxxx.dll but there is
xxxx.dll. This makes the test program look for the module files
correctly.
This makes use of the string we now have from glib-private.h in the
last commit so that setlocale() sets the default system locale
correctly and therefore show the translated messages properly.

Using the generic marshaller has drawbacks beyond performance. One such
drawback is that it breaks the stack unwinding from the Linux kernel due
to having unsufficient data to walk past ffi_call_unixt64. That means that
performance profiling by application developers looks grouped among
seemingly unrelated code paths.
While we can't fix the kernel unwinding here, we can provide proper
c_marshallers and va_marshallers for objects within Gio so that
performance profiling of applications is more reliable.
Related to GNOME/Initiatives#10
If c_marshaller is provided during g_signal_new() registration, the
automatic va_marshaller will not be set. If we leave the c_marshaller as
NULL in the simple cases, both a c_marshaller and va_marshaller will be
set for us.
This is particularly helpful when dealing with stack traces from Linux
perf, which often cannot unwind the stack beyond the ffi_call_unix64
stack-frame on x86_64.

This ensures that D-Bus connections established with unix:dir and
unix:path addresses actually work properly. Previously, we only tested
unix:tmpdir and TCP addresses.
This is not going to have much any effect currently since stop() just
disconnects a signal handler (that is going to be disconnected in
finalize anyway) and stops the socket service (that is going to be
destroyed in finalize), but it makes sense to do here for robustness.
unix:dir= addresses are exactly the same as unix:tmpdir= addresses,
already supported by GDBus, except they forbid use of abstract sockets.
This is convenient for situations where abstract sockets are
impermissible, such as when a D-Bus client inside a network namespace
needs to connect to a server running in a different network namespace.
An abstract socket cannot be shared between two processes in different
network namespaces.
Applications could use unix:path= addresses instead, so this is only a
convenience, but there's no good reason not to support unix:dir=.
Currently it is not supported simply because unix:dir= is a relatively
recent addition to the D-Bus spec.
It's somewhat unrealistic to use a GDBusServer without a
GDBusAuthObserver, because most D-Bus servers want to be like the
standard session bus (the owning user can connect) rather than being
like the standard system bus (all users can connect, the server is a
security boundary, and many bugs are security vulnerabilities).

Add a case for when the IPv6 result comes back negative and the IPv4

for an IPv6 address lookup, we should wait for the IPv4 lookup to

The current code was not doing that: it was rather setting a timeout for
failing the resolution entirely. In scenarios where the IPv4 response
comes more than 50ms after the IPv6 response (which is easily attainable
under valgrind in certain configurations) this means that the IPv4

file_copy_fallback creates new files with default permissions and
set the correct permissions after the operation is finished. This
might cause that the files can be accessible by more users during
the operation than expected. Use G_FILE_CREATE_PRIVATE for the new
files to limit access to those files.
When an application is launched using Launch Services
osx will add an extra parameter which we were not
handling and then gapplication would abort. Instead we make
an initial parsing and like this we avoid the abort if this
parameter is provided

The caller cannot assume that the lists returned by various GSettings
functions (for example, lists of keys or schemas) will be returned in
any particular order.

Helps: #1781
The parent GNetworkAddress contains a shared list of resolved
addresses that is used as a cache for multiple enumerations.
This commit ensures that the cache is only set upon completion of
DNS lookups and only read once by enumerations to avoid being in a
bad state.
Fixes#1771
We miss releasing the async operation's reference on a state object in
one of the error cases.
The call to connection_attempt_remove() (although it calls unref
internally) is not sufficient because this is releasing the reference
that the list owns.
Closes#1774
Spotted in https://gitlab.gnome.org/GNOME/mutter/issues/586. Bad input
on GAppLaunchContext environment manipulation functions is caught by
inner code, but the warning is not seemingly related.
Add precondition checks to these functions so it's clear where does the
bad input come from.
