This avoids failure to listen on the given address on non-Linux Unix
kernels, where abstract sockets do not exist and so unix:tmpdir is
equivalent to unix:dir.
To avoid bugs like this one recurring, run most of these tests using
the unix:dir address type, where Linux is equivalent to other Unix
kernels; just do one unix:tmpdir test, to check that we still
interoperate with libdbus when using abstract sockets on Linux.

Previously, we used unix:tmpdir, except in tests that verify that a
particular address type works (notably unix:dir). Now we use unix:dir
most of the time, and unix:tmpdir gets its own test instead.
This helps to ensure that the tests continue to work on non-Linux Unix
kernels, where abstract sockets do not exist and so unix:tmpdir is
equivalent to unix:dir, even in the common case where the developer has
only tried the test on Linux.

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
the rest of GLib.

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).

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 plugin modules in these tests get statically linked with a separate
copy of GLib so they end up calling vfuncs in their own copy of GLib.

We need to enable building the dirent and gnulib sources for clang-cl,
as we are still using the Microsoft-style headers and lib's and CRT.
We need to also do this for the following, for similar reasoning:
-Symbol export (via __declspec(dllexport))
-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
by clang-cl.
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.

There seems to be no reason to do so, and since the `appinfo` test was
ported to use `G_TEST_OPTION_ISOLATE_DIRS`, it has been causing
coredumps to accumulate. `gnome-terminal` was chosen as the terminal,
but it couldn’t find its GSettings schemas due to all the XDG
environment variables being cleared to `/dev/null` by
`G_TEST_OPTION_ISOLATE_DIRS`.
In order to keep using `gnome-terminal` as a subprocess in the tests,
we’d need to explicitly set up its environment so it can load the right
GSettings schemas. That’s a lot of work for not much gain.

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 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.
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).

The test performs implicit autolaunching of a bus
and checks if it is connectible.
In build the test is moved from "only non-windows with have_dbus_daemon"
to "anywhere".
This is intentional: actually it doesn't execute any external
binaries on unix (so doesn't require dbus_daemon)
and now has win32 implementation.
The test has some problems that are not problems of test itself,
but are reasoned by current win32 implementation:
- since the implementation uses global win32 kernel objects
with fixed names not depending on g_get_user_runtime_dir or other context
if preexisting bus running by some other libgio-using application
the test would silently pass.
- since the implementation uses problematic time-based synchronization,
that has a race condition between opening and reading mmaped address,
the test may randomly fail (I'd not seen this in practice).
- since the implementation autolaunched process works for 3 seconds
after last client disconnects, the executed subprocess runs for 3 seconds
after test exit, maybe locking the libgio-2.0-0.dll file for that time.

It’s occasionally possible for the cancellation of the service to happen
before connection_cb() gets scheduled in the other thread. The

• test_threaded_712570(): start wait loop

• test_threaded_712570(): end wait loop
• test_threaded_712570(): unlock mutex

On about 1 in 3 test runs, the socket-service would fail with the
ref_count assertion in connection_cb() failing (the ref_count would be 3
rather than the expected 2).
This was happening because the GTask from
g_socket_listener_accept_socket_async() now always takes at least one
main context iteration to return a result (whereas before
6f3d57d2ee it might have taken zero), but
the ref_count can drop below 3 before the process of returning a result
starts. During the process of returning a result, the ref_count
temporarily increases again, which is what was breaking the test.
Fix this by waiting for one more main context iteration. This is a bit
of a hack, but the real fix would be to expose the outstanding_accept
boolean from GSocketService as public API (which the test can
interrogate), and that seems too much like exposing internal state.

getsockname() returns the address that the socket was bound to.
If it was bound to INADDR_ANY, getsockname() will stubbornly return INADDR_ANY
(and someport - that one is valid).
Subsequent connection attempts to INADDR_ANY:someport will fail with winsock.
Actually, it doesn't make even sense to connect to INADDR_ANY at all
(where is the socket connecting to? To a random interface of the host?),
so this is just a straight-up change, without platform-specific ifdefing.
Use loopback instead of INADDR_ANY. To ensure that binding and creation
of INADDR_ANY is still tested, use two addresses: bind to INADDR_ANY,
but connect to loopback, with the port number that we got from the bound
address.
The gsocketclient-slow test needs this, otherwise connect() succeeds
immeidately and the test fails, because it is checking that cancellation
works. We weren't installing it for installed tests.
It's necessary sometimes for installed tests to be able to run with a
custom environment. For example, the gsocketclient-slow test requires an
LD_PRELOADed library to provide a slow connect() (this is to be added in
a followup commit).
Introduce a variable `@env@` into the installed test template, which we
can override as necessary when generating `.test` files, to run tests
prefixed with `/usr/bin/env <LIST OF VARIABLES>`.
As the only test that requires this currently lives in `gio/tests/`, we
are only hooking this up for that directory right now. If other tests in
future require this treatment, then the support can be extended at that
point.
There's no /tmp directory on Windows.
Use g_get_tmp_dir(), and adjust the test to work with that.
The test *still* checks the basename of the new CWD, it just
doesn't need to be "tmp" anymore.
envp in spawn() functions is the *whole* environment table
for the child process. Including PATH. Thus, unless PATH is explicitly
put into that table, the process will be spawned without PATH.
Since on Windows binaries are found via PATH instead of LD_LIBRARY_PATH
or whatever, almost no program (unless installed in WINDIR, maybe)
can run without a PATH. Certainly not test programs - meson
adds bld subdirs to the PATH to make sure that test programs
use uninstalled glib at runtime.
So make sure that PATH is passed along.
Windows \r\n EOLs strike again. The test already knows about LINEEND,
so make it use LINEEND more (instead of swithcing pipes
to binary mode). This also applies to counting the bytes
read.
With winsock sending messages to NULL results in G_IO_ERROR_NOT_CONNECTED
instead of G_IO_ERROR_FAILED.
MSDN says:
WSAENOTCONN
10057
Socket is not connected.
A request to send or receive data was disallowed because the socket is not connected
and (when sending on a datagram socket using sendto) no address was supplied.
So this is a direct mapping of the implementation error.
Covering it up in the wrapper (by converting it to G_IO_ERROR_FAILED)
doesn't seem feasible or needed (no one, except for the testsuite,
really cares which unrecoverable error is returned by sendto()).
getaddrinfo() in winsock can't understand scope IDs.
There's no obvious way to fix that, short of re-implementing
that function, so disable that part of the test on Windows.
Previously once the end of addresses was reached it would return
NULL even if it was waiting on a dns response. Now it will keep
waiting so all addresses are received.
Fixes#1680
Currently, the actual asynchronous work, represented by
asynchronous_cancellation_run_task, was over before the GCancellable
could be triggered. While that doesn't invalidate the purpose of the
test, since it's fundamentally about cancellation, it would be
nicer if the cancellation actually served some purpose instead of
being a mere formality.
