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

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.

These tests were originally written using the output directly from a
fuzzer which had triggered the bugs we’re testing for. However, that
means they’re liable to no longer test what they’re intended to test if
the `GDBusMessage` parsing code is changed to (for example) check for
certain errors earlier in future.
It’s better to only have one invalidity in each binary blob, so change
the test messages to all be valid apart from the specific thing they’re
testing for.
The changes were based on reading the D-Bus specification directly:
https://dbus.freedesktop.org/doc/dbus-specification.html
During these changes I found one problem in
`test_message_parse_deep_header_nesting()` where it wasn’t actually
nesting variants in the header deeply enough to trigger the bug it was

This incidentally also exercises the intended pattern for sending fds in
a D-Bus message: the fd list is meant to contain exactly those fds that
are referenced by a handle (type 'h') in the body of the message, with
numeric handle value n corresponding to g_unix_fd_list_peek_fds(...)[n].
Being able to send and receive file descriptors that are not referenced by
a handle (as in OpenFile here) is a quirk of the GDBus API, and while it's
entirely possible in the wire protocol, other D-Bus implementations like
libdbus and sd-bus typically don't provide APIs that make this possible.

This test ensures that g_socket_client_connect_to_host_async() fails if

the crash locally as well. Switching it from 1ms to 0ms is enough for

By default, when using g_subprocess_launcher_take_fd() to pass an
FD to a child, the GSubprocessLauncher object also takes ownership
of the FD in the parent, and closes it during finalize(). This is
a reasonable assumption in the majority of the cases, but sometimes
it isn't a good idea.
An example is when creating a GSubprocessLauncher in JavaScript:
here, the destruction process is managed by the Garbage Collector,
which means that those sockets will remain opened for some time
after all the references to the object has been droped. This means
that it could be not possible to detect when the child has closed
that same FD, because in order to make that work, both FDs
instances (the one in the parent and the one in the children) must
be closed. This can be a problem in, as an example, a process that
launches a child that communicates with Wayland using an specific
socket (like when using the new API MetaWaylandClient).
Of course, it isn't a valid solution to manually call close() in
the parent process just after the call to spawn(), because the FD
number could be reused in the time between it is manually closed,
and when the object is destroyed and closes again that FD. If that
happens, it will close an incorrect FD.
One solution could be to call run_dispose() from Javascript on the
GSubprocessLauncher object, to force freeing the resources.
Unfortunately, the current code frees them in the finalize()
method, not in dispose() (this is fixed in !1670 (merged) ) but it
isn't a very elegant solution.
This proposal adds a new method, g_subprocess_launcher_close(),
that allows to close the FDs passed to the child. To avoid problems,
after closing an FD with this method, no more spawns are allowed.

Expose a function that prepares an attribute query string to be passed
to g_file_query_info() to get a list of attributes normally copied with
the file. This function is used by the implementation of
g_file_copy_attributes, and it's useful if one needs to split
g_file_copy_attributes into two stages, for example, when nautilus does
a recursive move of a directory. When files are moved from the source
directory, its modification time changes. To preserve the mtime on the
destination directory, it has to be queried before moving files and set
after doing it, hence these two stages.

It seems that allowing the GCancellable to be finalised in either the
main thread or the worker thread sometimes leads to crashes when running
on CI.
I cannot reproduce these crashes locally, and various analyses with
memcheck, drd and helgrind have failed to give any clues.
Fix this for this particular test case by deferring destruction of the
`GCancellable` instances until after the worker thread has joined.
That’s OK because this test is specifically checking a race between
`g_cancellable_cancel()` and disposal of a `GCancellableSource`.
The underlying bug remains unfixed, though, and I can only hope that we
eventually find a reliable way of reproducing it so it can be analysed

This ensures that we do really export the symbols for Visual
Studio-style builds, by using _GLIB_EXTERN to decorate the generated

actually exported.
Sometimes this test was timing out due to the file monitor notifications
taking longer than the arbitrary 2s delay before ending the test and
checking its results at the end of `iclosed_cb()`.
Avoid that timing-dependence by ending the test when the expected file
monitor notifications are seen, or after a 10s timeout (if so, the test
is failed).
This makes the test run 4× faster in the normal case, as it’s no longer
waiting for a timeout to elapse if the file monitor notifications come

The test added for #1841 spawned 100000 threads. That was fine on a
desktop machine, but on a heavily loaded CI machine, it could result in
large (and unpredictable) slowdowns, resulting in the test taking over
120s in about 1 in 5 runs, and hence failing that CI pipeline due to a
timeout. When passing normally on CI, the test would take around 90s.
Here’s a histogram of time per iteration on a failing (timed out) test
run. Each iteration is one thread spawn:

Commit 721e385 left one remaining race in the filter test, with a
comment associated with it. Unfortunately, the (seemingly unrelated)
changes in #1841 to `GCancellable` seem to have made this remaining race
a lot more likely to fail on FreeBSD than before.
What’s likely to have happened (although I was unable to reproduce the
failure, due to not having a FreeBSD system; I was only able to
reproduce the problem as a 3/1000 failure on Linux, which is still worth
fixing) is that the atomic write of the `FilterData.serial` to be
expected by the filter function sometimes happened after the filter
function had executed, so the expected message was dropped and didn’t
result in an update to the `FilterData` state.
Rework the test so that instead of setting some expectations (on
`FilterData`) in one thread and then checking them in another thread,
the worker thread just unconditionally returns messages from the filter
function to the main thread, and then the main thread checks whether the
expected one has been filtered.
With this change applied, the `gdbus-connection` test passes 5000 times
in a row for me, on Linux; and doesn’t seem to fail any more on the
FreeBSD CI machines over a few runs. (Previously it failed on 4/5 runs.)

There’s a minor race condition between cancellation of a `GCancellable`,
and disposal/finalisation of a `GCancellableSource` in another thread.
Thread A Thread B
g_cancellable_cancel(C)
→cancellable_source_cancelled(C, S)
g_source_unref(S)
cancellable_source_dispose(S)
→→g_source_ref(S)
→→# S is invalid at this point; crash
Thankfully, the `GCancellable` sets `cancelled_running` while it’s
emitting the `cancelled` signal, so if `cancellable_source_dispose()` is
called while that’s high, we know that the thread which is doing the
cancellation has already started (or is committed to starting) calling
`cancellable_source_cancelled()`.
Fix the race by resurrecting the `GCancellableSource` in
`cancellable_source_dispose()`, and signalling this using
`GCancellableSource.resurrected_during_cancellation`. Check for that
flag in `cancellable_source_cancelled()` and ignore cancellation if it’s
set.
The modifications to `resurrected_during_cancellation` and the
cancellable source’s refcount have to be done with `cancellable_mutex`
held so that they are seen atomically by each thread. This should not
affect performance too much, as it only happens during cancellation or
disposal of a `GCancellableSource`.

When testing that signals are delivered to the correct thread, and are
delivered the correct number of times, call `EmitSignal()` on the

Previously, the code listened for `NameOwnerChanged` and connected to
the bus again to trigger emission of that. The problem with that is that
other things happening on the bus (for example, an old
`gdbus-testserver` instance disconnecting) can cause `NameOwnerChanged`
signal emissions. Sometimes, the `gdbus-threading` test was failing the

Previously, the code in `ensure_gdbus_testserver_up()` created a proxy
object and watched its `name-owner` to see when the
`com.example.TestService` name appeared.
This ended up subscribing to three signals (one of them for name
ownership, and two unused for properties of the proxy), and was racy. In
particular, the `name-owner` property could be set before all D-Bus
messages had been processed — it could have been derived from getting
the owner of the name, for example.
This left unprocessed messages hanging around in the `context`, but that
context was never iterated again, which essentially leaked the
references held by those messages. That included a reference to the
`GDBusConnection`.
The first part of the fix is to simplify the code to use
`g_bus_watch_name_on_connection()`, so there’s only one signal
subscription to worry about.
The second part of the fix is to use the `GDestroyNotify` callback for
the watch data to be notified of when all D-Bus traffic has been
processed and the signal unsubscription is complete. At this point, it’s
guaranteed that there are no idle callbacks pending in the
`GMainContext`, since the `GDestroyNotify` callback is the last one
invoked on the `GMainContext`.
Essentially, this commit uses the `GDestroyNotify` callback as a
synchronisation message between the D-Bus worker thread and the thread
calling `ensure_gdbus_testserver_up()`.

This GLib API is good, but the implentation is not ready, so there's no

There are three problems: (a) The glib-networking implementation normally
works, but the test has been broken for a long time. I'm not comfortable
with adding a major new feature without a working test. This is
glib-networking#104. (b) The WebKit implementation never landed. There
is a working patch, but it hasn't been accepted upstream yet. This API
isn't needed in GLib until WebKit is ready to start using it.
https://bugs.webkit.org/show_bug.cgi?id=200805. (c) Similarly, even if
the WebKit API was ready, that itself isn't useful until an application
is ready to start using it, and the Epiphany level work never happened.
Let's try again for GLib 2.66. Reverting this commit now just means we
gain another six months before committing to the API forever. No reason

As with all D-Bus signal subscriptions, it’s possible for a signal
callback to be invoked in one thread (T1) while another thread (T2) is
unsubscribing from that signal. In this case, T1 is the main thread, and
T2 is the D-Bus connection worker thread which is unsubscribing all
signals as it’s in the process of closing.
Due to this possibility, all `user_data` for signal callbacks needs to
be referenced outside the lifecycle of the code which
subscribes/unsubscribes the signal. In other words, it’s not safe to
subscribe to a signal, store the subscription ID in a struct,
unsubscribe from the signal when freeing the struct, and dereference the
struct in the signal callback. The data passed to the signal callback
has to have its own strong reference.
Instead, it’s safe to subscribe to a signal and add a strong reference
to the struct, store the subscription ID in that struct, and unsubscribe
from the signal when the last external reference to your struct is
dropped. That unsubscription should break the refcount cycle between the
signal connection and the struct, and allow the struct to be completely
freed. Only with that approach is it safe to dereference the struct in
the signal callback, if there’s any possibility that the signal might be
unsubscribed from a separate thread.
The tests need specific additional main loop cycles to completely emit
the NameLost signal callback. Ideally they need refactoring, but this
will do (1000 test cycles passed).

1) When parsing the executable name out of the command line,
see if the executable is rundll32.exe. If that is the case,
use the DLL name from its first argument as the "executable"
(this is used only for matching, and Windows Registry matches
these programs by their DLLs, so this is correct; for running
the application GLib would still use the command line, with
rundll32).
2) If an app runs with rundll32, ensure that rundll32 arguments
can be safely quoted. Otherwise GLib will break them with its
protective quotation.
Currently the code generated by gdbus-codegen uses
G_DBUS_CALL_FLAGS_NONE in its D-Bus calls, which occur for each method
defined by the input XML, and for proxy_set_property functions. This
means that if the daemon which implements the methods checks for
G_DBUS_FLAGS_ALLOW_INTERACTIVE_AUTHORIZATION and only does interactive
authorization if that flag is present, users of the generated code have
no way to cause the daemon to use interactive authorization (e.g. polkit
dialogs).
If we simply changed the generated code to always use
G_DBUS_FLAGS_ALLOW_INTERACTIVE_AUTHORIZATION, its users would have no
way to disallow interactive authorization (except for manually calling
the D-Bus method themselves).
So instead, this commit adds a GDBusCallFlags argument to method call
functions. Since this is an API break which will require changes in
projects using gdbus-codegen code, the change is conditional on the
command line argument --glib-min-version having the value 2.64 or
higher.
The impetus for this change is that I'm changing accountsservice to
properly respect G_DBUS_FLAGS_ALLOW_INTERACTIVE_AUTHORIZATION, and
libaccountsservice uses generated code for D-Bus method calls. So
these changes will allow libaccountsservice to continue allowing
interactive authorization, and avoid breaking any users of it which
expect that. See
https://gitlab.freedesktop.org/accountsservice/accountsservice/merge_requests/46
It might make sense to also let GDBusCallFlags be specified for property
set operations, but that is not needed in the case of accountsservice,
and would require significant work and breaking API in multiple places.
Similarly, the generated code currently hard codes -1 as the timeout
value when calling g_dbus_proxy_call*(). Add a timeout_msec argument so
the user of the generated code can specify the timeout as well.
Also, test this new API. In gio/tests/codegen.py we test that the new
arguments are generated if and only of --glib-min-version is used with a
value greater than or equal to 2.64, and in gio/tests/meson.build we
test that the generated code with the new API can be linked against.
The test_unix_fd_list() test also needed modification to continue
working now that we're using gdbus-test-codegen.c with code generated
with --glib-min-version=2.64 in one test.
Finally, update the docs for gdbus-codegen to explain the effect of
using --glib-min-version 2.64, both from this commit and from
"gdbus-codegen: Emit GUnixFDLists if an arg has type `h` w/
min-version".
For the check "if (error != NULL)" to work as expected, the
create_server() (and create_server_full()) functions need to make
sure to return an error for all the possible failures, but this
might not always be the case.
Catch all the failures by testing for a non-NULL return value if there
was no error.
They didn’t match the prototype generated by `gdbus-codegen`, which
meant that the FD list was being iterated incorrectly. Secondly, the
document ID list returned by the method was not NULL terminated, which
could lead to reading off the end of the list.
Somehow, neither of these bugs caused problems on Linux, but they did
cause problems on FreeBSD.

From the commit message for that commit:
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.

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

for building GLib, because it mostly produces false positives throughout

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

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.

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.

Compilers get confused when variables are initialized by a function by
taking them as reference in an out argument; this, coupled with the fact
that C does not initialize variables by default, most commonly results
in a "maybe uninitialized" compiler warning.
When testing as root, changing the permissions of the keyfile will have
no effect on the writability since root bypasses these permissions. See
path_resolution(7). Skip the test in this case.
g_assert_*() give more informative error messages, and aren’t compiled
out when building with G_DISABLE_ASSERT.

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.

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.

In the writev() tests, the handling of cancellation is tested. However,
the GCancellable was cancelled after the writev_async() call was
started. Depending on the implementation of the writev() vfunc, the
operation could be done in a thread or in callbacks on the current
thread’s main loop. If done in a separate thread, there’s a chance that
enough of the write could happen before cancellation reaches that thread
that the overall operation returns success with a short write.
That would cause the test to fail, sometimes.
Avoid that by cancelling the GCancellable before starting the writev()
operation.

There's a race here, as revealed by Debian's buildds.
We call g_dbus_proxy_new() to create a proxy for the test server, with
callback proxy_ready() Then we call g_spawn_command_line_async() to
start the test server, and then start the main loop.
proxy_ready() assumes that the test server hasn't been started when it
is called. But there is no guarantee that these asynchronous operations
involving spawning a process won't happen in a different order that mean
the bus name *does* have an owner.
What we can do is move starting the server inside of proxy_ready(), so
we know that the test server isn't started until after the proxy is
created. We also add an assertion to check that it is indeed not running
before we execute it.
If we can't find the mount point for target or tmp (as currently
happens on Launchpad autobuilders, and perhaps relatedly, on a
development system that uses btrfs), that's probably not great but is
not really the point of this test.

appinfo-test-static.desktop uses an Exec= line which should always be

This test is intended to verify the fix for
https://bugzilla.gnome.org/show_bug.cgi?id=787731, which was that
g_file_query_filesystem_info() would return stale information for the
mount. After replacing a read-only mount with a read-write mount, this
test used to only fail if G_FILE_ATTRIBUTE_FILESYSTEM_READONLY was TRUE
and yet the file could be opened for writing. In particular, if (due to
a test bug) the file really was still on a read-only filesystem, the
test would pass.
Now that we have fixed that bug in the test, we can make a stronger
assertion.
fusermount -z behaves like umount --lazy, which is documented thus:
> Detach the filesystem from the file hierarchy now, and clean up all
> references to this filesystem as soon as it is not busy anymore.
Without this, the call to `fusermount -u` often fails with:
/usr/bin/fusermount: failed to unmount /home/wjt/src/gnome/glib/_build/dir_bindfs_mountpoint: Device or resource busy
which causes the subsequent call to bindfs to fail:
fuse: mountpoint is not empty
fuse: if you are sure this is safe, use the 'nonempty' mount option
It's not clear what is causing the mount to be busy. Inserting a
g_usleep (100 * 1000) before the calls to `fusermount -u` also works to
make the problem go away, but for the purposes of this test the
important point is that the mount is detached from the directory, for
which a lazy unmount is fine.
Fixes#1590.
In practice, fusermount -u often fails:
/usr/bin/fusermount: failed to unmount /home/wjt/src/gnome/glib/_build/dir_bindfs_mountpoint: Device or resource busy
which causes the subsequent calls to bindfs to fail:
fuse: mountpoint is not empty
fuse: if you are sure this is safe, use the 'nonempty' mount option
This may or may not cause the current test run to fail, but it reliably
causes a repeat run of the test to fail. This change causes the current
run to fail instead.
Currently, GDBusProxy:g-name-owner only notifies changes to the unique

That sounds like an artificial restriction, and it's convenient to

created for an unique name, instead of additionally using
g_bus_watch_name() to track the owner.
To fix this, always connect to NameOwnerChanged after the proxy is
initialized, instead of only doing so when the proxy was constructed for
a well-known name.

This is the most degenerate possible test but it does exercise this code
path.
(Tweaked by Philip Withnall <withnall@endlessm.com> to also add the flag

The executable depends only on the generated header file at compile
time, and on the library at link time. So meson can decide to compile
gdbus-peer.c before compiling the library and thus won't have generated
the header yet, causing the build error.
So declare_dependency() should only have the header file in its sources,
to force generating files before compiling gdbus-peer.c without
including objectmanager-gen.c into gdbus-peer's sources.
We use libgdbus_example_objectmanager_dep as dependency for various
tests, but this implies only a link dependency while it doesn't ensure
that the sources are generated.

On Windows NTFS symlinks are implemented as reparse points,
which are special kinds of files *or directories*. A directory
symlink should link to a directory. A file symlink should link
to a file. Mismatching (such as a file symlink pointing to a
directory) produces symlinks that simply do not function.
Therefore GFileType file vs directory vs symlink distinction is
too simplistic to correctly represent a NTFS filesystem object type.
Since we can't turn back time and choose a better way of representing
file types, make GFileType reflect the file vs directory type on
Windows, meaning that all FS objects are either files or
directories (or shortcuts, which are also files), but never symlinks.
A test for symlinkiness will have to be made via GFileInfo - it
tracks symlinkiness separately from file/directory/whatever.
When using glib as a meson subproject on Windows the build currently fails
due to too long paths during the build process. See
https://github.com/mesonbuild/meson/issues/4226 for the upstream bug.
To work around the issue shorten the filenames of the generated gdbus files.
The tests were making assumptions about the order of the returned D-Bus
introspection nodes. However, these are semantically unordered and
changes to e.g. GHashTable would break the tests.

The X-Flatpak-RenamedFrom key is used in .desktop files to identify past
names for the desktop file. It is defined to be a list of strings.
However, there was previously no correct way to retrieve a list of
strings from the GKeyFile wrapped by GDesktopAppInfo, short of
re-parsing the file with GKeyFile.
Note that doing something like:
g_strsplit (g_desktop_app_info_get_string (...), ";", -1)
is not correct: the raw value "a\;b;" represents the one-element list
["a;b"], but g_key_file_get_string() rejects the sequence "\;", and so
g_desktop_app_info_get_string() returns NULL in this case. (Of course, a
.desktop file with a semicolon in its name is a pathological case.)
Add g_desktop_app_info_get_string_list(), a trivial wrapper around
g_key_file_get_string_list(), similar to g_desktop_app_info_get_string()
and co.
The change from g_key_file_free() to g_key_file_unref() in the test is
needed because g_key_file_free() clears the contents of the keyfile.
This is fine for all the fields which are eagerly loaded and copied into
GDesktopAppInfo, but not when we want to access arbitrary stuff from the
keyfile.
This makes it easier to debug test failures, by ensuring that g_debug()

this was recently remove from glib-networking.

Define G_MESSAGES_DEBUG=all when running CI to ensure we won't regress

In order to determine whether to trash a file to the home directory, we
compare its st_dev to our home directory's st_dev field.
This is the wrong thing to do on overlayfs when deleting files, because
st_dev contains the ID of the filesystem providing the file (which can
be the lower or upper filesystem), but directories always return the ID
of the overlayfs. Thus the comparison fails and we are unable to trash
the file.
Fix this by checking st_dev of the parent directory when we are deleting
a file.
Also adjust `test_trash_not_supported` for this - make its st_dev check
look at the parent directory's `st_dev` rather than the temporary file's
own.

eliminated, which will enable use of the posix_spawn optimized
gspawn codepath for desktop app launching.
In order to use the new posix_spawn gspawn codepath, for more robust
app launching when available memory is low, we need to meet some
conditions.
child_setup needs to be NULL for this optimization to work, so drop
the internal child_setup that is used here. Replace it with a lightweight
wrapper binary (gio-launch-desktop) that sets GIO_LAUNCHED_DESKTOP_FILE_PID
before executing the app.
Adjust PATH for gio tests so that it can execute the new binary from the
build directory.
They’re network file systems, but not system file systems (in the sense
that procfs is a system file system). This fixes them disappearing from
the sidebar in the UI.

check_expected_events is heavily modified in this commit to tolerate
event loss and allow renaming to be reported as creation and deletion.
This fixes test failure on FreeBSD.
Previously, calling:
g_dbus_is_supported_address ("some-imaginary-transport:", NULL)
correctly returned FALSE; but calling:
g_dbus_is_supported_address ("some-imaginary-transport:", &error)
crashed with:
GLib-GIO:ERROR:../gio/gdbusaddress.c:434:g_dbus_is_supported_address:
assertion failed: (ret || (!ret && (error == NULL || *error != NULL)))
This was because, if the address component did not start with a known
transport, no error was set. Fix this, reusing an error string used by
the corresponding else branch in g_dbus_address_connect(), and adjust
the test to pass both NULL and non-NULL GError **s to this function in
every test case. This case:
g_assert (!g_dbus_is_supported_address ("some-imaginary-transport:foo=bar;unix:path=/this/is/valid", NULL));
would have caught this bug with a non-NULL GError **.
Meson has the ability to classify tests according to "suites", a list of
tags. This is especially useful when we want to run specific sets of
tests — e.g. only GLib's tests — instead of the whole test suite. It
also allows us to classify special tests, like "slow" ones, so that we
can only run them when needed.
Non-glibc gettext implementation seems to decide the language from
LC_MESSAGES environment variable instead of LC_MESSAGES locale, so
we should set both environment variable and locale when running tests
which need translation from specific languages.
Main changes were:
- take into account that style variants are added to the list of icon
names.
- In the test of icons set with 3 names ("first", "testicon" and
"last"), I also changed "first" to "first-symbolic" so that we can
test in such a case that the variant is the regular icon (only for
this name, out of the 3).
- Finally icon hashes are necessarily changed, and since emblems are
sorted by their hash in emblem icons, I had to invert an order which
was now different in one of the tests.
The previously implementation considered a file to be a mountpoint if
its parent is on a different device. / is its own parent, so by this
definition it is not a mountpoint.
But / is (generally) listed in fstab, and fstab(5) defines the
directories it contains to be mountpoints. This attribute should follow
that definition (and reasonable expectation): the root directory is a
mountpoint.
So, add a special-case for the case where the file's parent has the same
st_dev and st_ino as the file, which is true only at the root.
Test this attribute at / (only on POSIX), /proc (but only on Linux), and
at many files and directories created by the test suite (which cannot be
mountpoints).
Sometimes file monitor events may be slow to emit. Using g_idle_add
makes it less possible for events to be scheduled later than the main
loop quit, preventing test failure caused by missing events.
This fixes test failure on FreeBSD.
Kqueue isn't good at detecting rapid file creation and deletion. It
tends to miss events because events returned by the kernel don't include
filename information. Since the size of struct kevent is fixed, it is
probably not possible to extend the API to include file names without
breaking ABI. Therefore, we disables the test here to avoid test failure
that is impossible to fix in a reliable way.
The test 'file' uses non-standard '--bytes' option when running du,
which may cause error on non-GNU systems. To keep the test working,
we skips the du check as if we don't find a du command when du fails.
-export-dynamic is a libtool flag. It is also supported by GCC as an
undocumented flag, but it is not supported by Clang. Since we don't use
libtool in meson, we should use -Wl,--export-dynamic instead.
This test assumes the subprocess does not print anything else on stdout
other than the dbus address, otherwise g_test_trap_assert_stdout()
fails to match. But if the env running tests has G_MESSAGES_DEBUG=all
then it will also print "PATH=%s".

On non-glibc platforms gettext is provided by extra libintl dependency.
We wrongly thought libintl is an internal dependency and applications
needs to explicitly link on it, but turns out that breaks many

It inserted the new items one position after the given one and inserted all new items
at the same position resulting in the items being in the reverse order of the
input array.
It was decided to make these behavioural changes because this function has according to
https://codesearch.debian.net/search?q=g_list_store_splice only one real user (nautilus)
and it didn't do what one would expect from reading the documentation.

The monitor_path comes from g_file_get_path(), so should be freed with

This fix undefined symbol link error when building for non-glibc

g_desktop_app_info_load_from_keyfile() refuses to load .desktop files
where the executable doesn't exist. Therefore whether or not the .desktop
file added in commit 148995544 is actually considered during tests depends
on /usr/bin/flatpak being installed. This isn't a safe assumption to make,
so use /bin/sh to test filtering of "prefix" commands.

The executable name can be a useful bit of information to match on in
searches where it differs from the name (for example because the latter
is localised), but will produce surprising results where the real appli-
cation is executed by a shared binary (for example interpretors like
gjs or python, or sandboxes like flatpak).
Address this by adding a blacklist of binary names that are ignored
in search.

Add a test for monitoring an existing local file, with the

This test contains a FIXME where I suspect we should be getting some

This test will only work on machines which have IPv6 enabled and have a
local IPv6 interface with ID 1. On machines which don’t (such as AWS
servers, which we run CI tests on), the GResolver tests will fail with
G_RESOLVER_ERROR_INVALID. We can’t differentiate this kind of failure
(where we’d want to skip the test) from an actual failure (where we’d
want to fail the test), so the only other option is to drop this
particular test vector. I don’t think it’s a significant loss.
This is the last fix needed to get our CI tests working reliably on
jenkins.gnome.org.

While 333 runs is very likely to reproduce the bug, Milan has previously
reproduced it with as few as 9 runs. Since this test will be run by the
CI machinery quite often, a lower number of runs each CI run will still
probably catch any regressions over time.
This reduces the total test runtime from 33s to 2s.

When using g_network_monitor_get_default() from another thread, it’s
possible for network-changed events to be processed after an instance of
GNetworkMonitor has been disposed, causing use-after-free problems.
Fix that by moving some of the initialisation into the GInitable.init()
chain, rather than in a main context idle callback.
This includes a unit test which probabilistically reproduces the bug
(but can’t do so deterministically due to it being a race condition).

If glib-networking is installed and built with libproxy support, this
test will use it. If a proxy is set in the environment, we might get
correctly told to go through it for certain accesses. However, this isn't
going to work, because the testsuite monkeys with the network monitor to
tell it that all addresses - including the proxy - aren't reachable.
We're trying to check if adding networks to a GNetworkMonitor works in
general. Proxies just get in the way here, so let's use the built in
dummy proxy resolver which just tells us that all URLs are directly
accessible.

The `mount_monitor` variable is only set if the boolean
`with_mount_monitor` variable is set to TRUE, but the compiler does not
know that, so it'll warn when calling `g_clear_object()` even if the

Initializing with NULL does not cost us anything, and eliminates a

Tighten up the validation of application IDs so they are always exactly
D-Bus well-known names. This is a slight change to the accepted format,
but since anyone using the API with an application ID which was
previously valid, but which was not a valid D-Bus well-known name, would
have received an error from D-Bus when their application tried to
register on the bus, I think this break is acceptable.
It will affect any applications which have application IDs which are not
valid D-Bus well-known names, and which use the G_APPLICATION_NON_UNIQUE
flag. From a quick search in Debian Codesearch, no C applications use
that flag.
Update the documentation to use the rules from the D-Bus specification,
including the latest advice discouraging use of hyphens:
https://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-names-bus
Update the tests:
• Add the examples from the documentation to validate them.
• Especially the venerable 7-zip.org example.
• Move a couple of tests from expected-failure to expected-success:
they are valid D-Bus well-known names even if they’re a bit weird.
