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
result is significantly delayed. This is exactly the case that causes
the bug addressed by GNOME/glib!865
The "happy eyeballs" RFC states that on receiving a negative response
for an IPv6 address lookup, we should wait for the IPv4 lookup to
complete and use any results we get from there.
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
response will never come.
Remove the timeout and just wait.

More vectors will give an error and we can simply clamp here and

In case of GSocketOutputStream this is done here instead of inside
GSocket before calling sendmsg() because we we can't generically handle
short writes when sending messages on a socket, e.g. for datagram
sockets this causes only part of the datagram to be sent and an error
would be more useful in this case than sending corrupted data.

Since out-of-source-tree builds are now used after switching to meson,
we don't need .gitignore files in the source directories to ignore
build artifacts.
This fixes build errors when doing a meson build after an autotools
build, because generated files such as gio/xdp-dbus.c won't show up in
a `git status`, or be removed by a `git clean -f`, and so it won't be
obvious that such files need to be removed for the meson build to
succeed.
The `monitor` test was originally written to test GFileMonitor with
directories. Over time, `testfilemonitor` acquired units for testing
directories as well, which made the `monitor` test reduntant.

annotations to do their thing. It also broke libsoup, as it uses

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.
This is a bit of breaking change:
After this commit the apps relying of win32 dbus autolaunching,
need to install gdbus.exe alongside with libgio-2.0-0.dll.
A new command for gdbus tool is used for running server:
gdbus.exe _win32_run_session_bus
To implement it gdbus.exe uses the same exported function
g_win32_run_session_bus that earlier was used by rundll.
So (private) ABI was not changed.
It runs the bus syncronously, exiting after inactivity timeout -
all exactly like it was runed earlier with the help of rundll32.
While private exported function may have _some_
version compatibility issues between gdbus.exe and libgio-2.0-0.dll
compiling dbus server registration logic directly into gdbus.exe
can lead to _more hidden and more complex_ compatibility issues
since the names and behaviour of syncronization objects
used to publish server address would be required compatible between
gdbus.exe and libgio-2.0-0.dll.
So using "private" exported function to call
looks like more safe behaviour.
gdbus.exe binary was selected for this task since
it has corresponding name and at least for msys2 is shippied
in same package with libgio-2.0-0.dll
turn_off_the_starting_cursor function is also kept as is,
however it is not obvious if it is still needed
(by now I failed reproducing original issue).
Explicit g_warnings added to help with possible
problematic cases for absent or incompatible gdbus.exe
Mainloop is created after successful daemon creation
Before this change the function leaked mainloop on daemon creation fail
nm_conn_to_g_conn already handles UNKNOWN like NONE (returning
G_NETWORK_CONNECTIVITY_LOCAL in both cases). So in sync_properties
we should also set new_connectivity to G_NETWORK_CONNECTIVITY_LOCAL
for both NM_CONNECTIVITY_UNKNOWN and NM_CONNECTIVITY_NONE.
This has the added benefit that when NetworkManager returns the network
connectivity is UNKNOWN, we set network_available to FALSE as it should
be. Previously, there were cases in a laptop with no network access,
that g_network_monitor_get_network_available returned true, which was
wrong and is also fixed with this commit.

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.
Use a static GQueue to form the GList of mounts by appending (which
is fast, because GQueue tracks the tail pointer of its internal GList),
then return that GList. This way we don't need to form the list
by prepending, which would have made it necessary to reverse it before
returning.
If the list is not ordered correctly, local drives in GTK places sidebar
are shown in reverse order.
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.
G_RESOURCE_OVERLAYS is a list of resource-path and filesystem-path pairs.
Since on Windows filesystem paths use ':', this list can't be ':'-separated
there. Fix that by making it ';'-separated on Windows. Make the parser
error clearer (we're not looking for a slash, we're looking for an absolute
path).
If a URI can't be handled by by WinHTTPVfs, it should pass that URI
along to the URI parser of the wrapped Vfs, not to its generic parser.
Theoretically, generic parser should also be able to handle URIs,
but this is subject to Vfs semantics.
In case of Windows, the wrapped Vfs is GLocalVfs, which is *local* and
treats any generic names as either file:// URIs or as filesystem
paths. It only ever treats URIs as URIs when they are passed
to its URI parser. This breaks the testsuite when g-icon GIO test passes
unhandleable sftp:// URI, and expects it to come through unmolested,
yet GLocalVfs, getting that URI as a generic parse name, treats it as
a filesystem path, and then "canonicalizes" it by prepending CWD.
Fix this by making WinHTTPVfs pass any URIs it gets to the URI parser
of the wrapped Vfs. This way unknown URIs remain URI-ish. This seems
like a reasonable things to do, since the URI parser should not be
given anything other than URIs, so there's no reason to try generic
parsing with these strings.

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.

When calling g_socket_listener_accept_socket_async() on a
GSocketListener with multiple sockets, the accept_ready() callback is
called for the first incoming connection on each socket. It will return
success/failure for the entire accept_socket_async() GTask, and then
free the GSources for listening for incoming connections on the other
sockets in the GSocketListener. The GSources are freed when the GTask is
finalised.
However, if incoming connections arrive for multiple sockets within the
same GMainContext iteration, accept_ready() will be called multiple
times, and will call g_task_return_*() multiple times, before the GTask
is finalised. Calling g_task_return_*() multiple times is not allowed.
Propagate the first success/failure, as before, but then ignore all
subsequent incoming connections until the GTask is finalised.

Once cancelled, a GTask's callback should not only be invoked
asynchronously with respect to the creation of the task, but also with
respect to the GCancellable::cancelled handler. This is particularly
relevant in cases where the cancellation happened in the same thread
where the task is running.

It needs investigating and fixing properly, but let’s not let it disrupt
the CI in the meantime.

To make things consistent across the board as that is the WinSock2 error
code that is received by g_socket_send_message_with_timeout() when it
returns G_POLLABLE_RETURN_WOULD_BLOCK.
This never caused any problems because the default GSettingsBackend is
cached forever by GIOModule anyway.

I was trying to debug some memory leaks in the gsettings test.
Eventually, it seems that actually they’re caused by the
GMemorySettingsBackend being cached by GIOModule — so this commit makes
no functional changes. It should make the code and documentation a bit
clearer though.
