ec03755355 gio-tool-info: Fix a duplicate attribute name in the UI
`gio info` currently prints ‘display name:’ twice. One of those should
be ‘edit name:’ — this regressed in commit
a374b7c806.

Various translations still have the old string, but some unfortunately
do not, so this is effectively a new translatable string again.

1a9be3a1c8 tests: Add a test for D-Bus activating an unknown app with a context
This should catch regressions in the critical warning fixed in the
previous commit.

The launch has to have several conditions:
 - Session bus is running (to avoid the launch happening via the spawn
   codepath)
 - Use a non-existent D-Bus name (to trigger a launch error)
 - Use a launch context (to hit the critical warning code path)
 - Not have a startup ID specified in the platform data — this implies
   having an empty launch context
 - Use an async launch, as that provides an error handling path

764f8426d4 tests: Remove explicit timeout handler from gdbus-auth tests
The timeout runs for the entire duration of the test, which is a
function that Meson’s test harness already provides for us.

Meson’s timeout can be easily adjusted by a factor to allow for running
tests more slowly under valgrind. The timeout in the code cannot, which
leads to spurious failures like

406143b072 gfile: Fix file size detection when copying on btrfs
When the `g_file_copy` function is used with files on BTRFS, the
`GLib-GIO-FATAL-CRITICAL: GFileInfo created without standard::size`
error is printed. This is because the `g_file_get_size` function
is used to obtain the file size for the progress callback, but it uses
the wrong `GFileInfo` object that is meant for attributes to be copied
with the file. The file size attribute is missing there obviously. Let's
obtain the file size over the `fstat` call the same way as it is done in
the `splice_stream_with_progress` function to get rid of those errors
and to fix the progress reporting.

d5710deb9d gdbusinterfaceskeleton: Fix a use-after-free of a GDBusMethodInvocation
This `GDBusMethodInvocation` may be shared across threads, with no
guarantee on the strong ref in one thread outlasting any refs in other
threads — so it needs a ref in this helper struct.

This should fix a use-after-free where the `GDBusMethodInvocation` is
freed from `g_value_unset()` after `g_signal_emit()` returns in
`dispatch_in_thread_func()` in one thread; but then dereferenced again
in `g_source_destroy_internal()` from another thread.

1f86923766 gdbusinterfaceskeleton: Remove an unnecessary helper struct member
The `GDBusInterfaceSkeleton` is already stored as the source object of
the `GTask` here, with a strong reference.

Storing it again in the task’s data struct is redundant, and makes it
look like the `GDBusInterfaceSkeleton` is being used without holding a
strong reference. (There’s not actually a bug there though: the strong
reference from the `GTask` outlives the data struct, so is sufficient.)

Remove the unnecessary helper struct member to clarify the code a bit.

5a69cc22dc gdbusconnection: Explicitly destroy an idle source on cleanup
Otherwise it’s possible for it to hang around in the `GMainContext`
after the “send message” operation has finished. In the best case, this
will cause the `GTask` and `GDBusMessage` to not be freed when the
calling code expects. In the worst case, it could cause use-after-free
problems if it derefs allocations which have since been freed.

I have not seen either of these problems in practice, but it would be
best for the code to eliminate the risk of them altogether by explicitly
destroying the source when the operation is finished.

4900ea5215 gdbusconnection: Fix double unref on timeout/cancel sending a message
This appears to fix an intermittent failure seen when sending a D-Bus
message with either of a cancellable or a timeout set.

In particular, I can reliably reproduce it with:
```
meson test gdbus-test-codegen-min-required-2-64 --repeat 10000
```

It can be caught easily with asan when reproduced. Tracking down the
location of the refcount mismatch was a little tricky, but was
simplified by replacing a load of `g_object_ref (message)` calls with
`g_dbus_message_copy (message, NULL)` to switch `GDBusMessage` handling
to using copy semantics. This allowed asan to home in on where the
refcount mismatch was happening.

The problem was that `send_message_data_deliver_error()` takes ownership
of the `GTask` passed to it, but the
`send_message_with_replace_cancelled_idle_cb()` and
`send_message_with_reply_timeout_cb()` functions which were calling it,
were not passing in a strong reference as they should have.

Another approach to fixing this would have been to change the transfer
semantics of `send_message_data_deliver_error()` so it was `(transfer
none)` on its `GTask`. That would probably have resulted in cleaner
code, but would have been a lot harder to verify/review the fix, and
easier to inadvertently introduce new bugs.

The fact that the bug was only triggered by the cancellation and timeout
callbacks explains why it was intermittent: these code paths are
typically never hit, but the timeout path may sometimes be hit on a very
slow test run.

8f02681f6e gdbus: Never buffer reads during server authentication
Otherwise, the content of the buffer is thrown away when switching
from reading via a GDataInputStream to unbuffered reads when waiting
for the "BEGIN" line.

(The code already tried to protect against over-reading like this by
using unbuffered reads for the last few lines of the auth protocol,
but it might already be too late at that point.  The buffer of the
GDataInputStream might already contain the "BEGIN" line for example.)

This matters when connecting a sd-bus client directly to a GDBus
client.  A sd-bus client optimistically sends the whole auth
conversation in one go without waiting for intermediate replies.  This
is done to improve performance for the many short-lived connections
that are typically made.

937c6f15cd gfileinfo: Document required attributes for helper getters
It doesn’t make sense to (for example) call `g_file_info_get_name()` if
the `GFileInfo` doesn’t contain `G_FILE_ATTRIBUTE_STANDARD_NAME`, given
that building the `GFileInfo` is typically a static process and entirely
under the control of the programmer.

By being this restrictive, we avoid having to return ‘unknown’ values
for some of these standard APIs, particularly the numeric ones such as
`g_file_info_get_size()`. If APIs like that were to work correctly in
the face of a `GFileInfo` without `G_FILE_ATTRIBUTE_STANDARD_SIZE`
specified, they’d have to be able to return a value to indicate the
attribute is missing. Returning `0` or `G_MAXSIZE` to indicate that
would be ambiguous.

fix underspecified dependencies on generated headers
Since gmodule-visibility.h is now a custom target and produced at
buildtime, it might not always exist in time for use in other source
files. This was the case for gio-inotify.

Add it as an additional source file to ensure in-time generation.

2643961845 inotify: Avoid empty root directory string
When gio monitors a directory, it will delete the extra "/" at the end
of the directory string, but when the directory is "/", this will cause
the modified directory string to be empty, and eventually the
monitoring will fail. The solution is to delete only if the directory
string length is greater than 1.

Currently, inbuf_size and outbuf_size are not documented as not

this commit adds the appropriate GI annotations and early returns on

c434743111 Fix build of gio/ttests/est_resources2.o with LLVM objcopy
LLVM objcopy's --strip-all is more aggressive that GNU objcopy --strip-all
and will remove everything that is not actually used. In this case we
see the following error:
`error: 'gio/tests/test_resources.o': Symbol table has link index of 5 which is not a valid index`

6d93568e36 Fix building gio/tests/test_resources.o with LLVM ld
Unlike GNU ld which has a default target architecture, ld.lld is always a
cross-linker and has the same behaviour for all targets. If you don't tell
ld.lld what the target architecture is it can't infer the right ELF flags
for the resulting object file.
```
$ ~/cheri/output/sdk/bin/ld -r -b binary gio/tests/test5.gresource -o gio/tests/test_resources.o -v
LLD 14.0.0 (compatible with GNU linkers)
ld: error: target emulation unknown: -m or at least one .o file required
```

As you can see from the error message it can't infer the target
architecture (you need a least one valid .o file or the -m flag).
If you use the compiler instead of directly invoking the linker it will
pass the appropriate flags:
```
$ ~/cheri/output/sdk/bin/clang -r -Wl,-b,binary gio/tests/test5.gresource -o gio/tests/test_resources.o -v
clang version 14.0.0 (https://github.com/CTSRD-CHERI/llvm-project.git ff66b683475fc44355b2010dbcbe1202d785e6f8)

Now that there is g_string_free_and_steal (), we can use it instead of
the older g_string_free (_, FALSE). Make sure to use its return value
while doing so, as opposed to manually accessing string->str, to avoid
compiler warnings and make the intent more explicit.

This is all done in preparation for making g_string_free (_, FALSE) warn
on unused return value much like g_string_free_and_steal (), which will

73205b8bbd tests: Explicitly remove a timeout handler in gapplication test
Otherwise if, for whatever reason, the `app` loses its D-Bus name,
`g_application_quit()` is called from `name_was_lost()` before it’s
called from `quit_already()`, and then `quit_already()` does an invalid
read on `app`.

If the name was not meant to be lost at this point in the test, the
subsequent `g_assert_false (name_lost)` will catch that, so this change
shouldn’t cause the test to pass unnecessarily.

a56bc06f16 glocalfileinfo: Don't reset mtime tv_sec when setting tv_usec
Fix a regression that appeared after adding support for nanosecond
timestamps to set_mtime_atime(). User-visible effect: when copying a
file from a gvfs MTP mountpoint to the local filesystem, the file's
mtime is set to 0.

This behavior happens when setting G_FILE_ATTRIBUTE_TIME_MODIFIED first,
then G_FILE_ATTRIBUTE_TIME_MODIFIED_USEC. Setting the second attribute
ends up in set_mtime_atime() with mtime_usec_value set, and mtime_value
== NULL. When mtime_value is NULL, the tv_sec part of the timestamp
should be fetched by lazy_stat(), but set_mtime_atime() fails to assign
it properly, and tv_sec stays at 0, leading to losing the main part of
the timestamp.

Fix the issue by setting times_n[1].tv_sec to the value fetched from
lazy_stat().

When launching a registered handler we compose the command-line
string using the registered command-line template. Applications
expect files in their command-line as local paths rather than
complete URI strings.

For example,

  "Program.exe" "%1"

Should expand to

  "Program.exe" "C:\file.dat"

Rather than

  "Program.exe" "file:///C:\file.dat"

I noticed this when running the test on an Arm Morello system where varargs

On most other architectures this will just read whatever value is contained

it never resulted in test failures.

cdda03a690 GCancellable: Ensure it is always cancelled on connect callback
When a cancellable is cancelled when we call g_cancellable_connect we
used to immediately call the provided callback, while this is fine we
actually had race in case the cancellable was about to be reset or in
the middle of a cancellation.

In fact it could happen that when we released the mutex, another thread
could reset the cancellable just before the callback is actually called
and so leading to call it with g_cancellable_cancelled() == FALSE.

So to handle this, make disconnect and reset function to wait for
connection emission to finish, not to break their assumptions.

This can be tested using some "brute-force" tests where multiple threads
are racing to connect and disconnect while others are cancelling and
resetting a cancellable, ensuring that all works as we expect.

a2c8a8c630 tests: Release GApplication a little later to avoid assertion failures
If it takes one more `GMainContext` cycle than expected for the
`activate` signals to be handled, the `GApplication` under test can be
released too early, and the test will fail due to not seeing a high
enough value of `n_activations`.

Hopefully avoid that by moving the release to a low priority idle
callback.

This fix is only hopeful because I’ve only been able to reproduce the

511d1cad02 gdesktopappinfo: Fail early if trying to launch an invalid executable
GDesktopAppInfo never failed in the most simple of the cases: when a
desktop file or a command line app info was pointing to an invalid
executable (for the context).

The reason for this is that we're launching all the programs using
gio-launch-desktop which will always exist in a sane GLib installation,
and thus our call to execvp won't ever fail on failure.

This was partially mitigated by not allowing to create a desktop app
icon using a non-existent executable (even if not fully correctly) but
still did not work in case a custom PATH was provided in the launch
context.

To avoid this, use g_find_program_for_path() to find early if a program
that we're about to launch is available, and if it's not the case return
the same error that g_spawn_async_with_fds() would throw in such cases.

While this is slowing a bit our preparation phase, would avoid to leave
to the exec function the job to find where our program is.

Add tests simulating this behavior.

The platform data comes from the parent process, which should normally

`LD_LIBRARY_PATH`).

However, it can also come from any process which calls `CommandLine`
over D-Bus, so always has to be able to handle untrusted input. In
particular, `v`-typed `GVariant`s must always have their dynamic type
validated before having values of a static type retrieved from them.

These actions are activated as a result of receiving the `ActionInvoked`

Without validating the action and its parameter, assertions will be hit

f0606d5421 file-info: Add a set of attributes for large thumbnails
Some applications (eg., gnome-photos) really want a large thumbnail,
if one can be created. Simply falling back to a smaller one (probably
created by an old nautilus), without giving the application a chance
to create a bigger thumbnail, is undesirable because they will appear
fuzzy.

Therefore, at separate attribute sets for all the thumbnail sizes
that are supported in the spec: normal/large/x-large/xx-large.

The old attribute will now return by default the biggest available, as
it used to be, but also including the x-large and xx-large cases.

b7b9f89417 gdbusaddress: Use runstatedir rather than localstatedir
This reworks commit 20e1508e6e, for two
reasons:
 - Upstream dbus.git now does the same (although this isn’t yet reflected
   in the online version of the D-Bus Specification); see
   https://gitlab.freedesktop.org/dbus/dbus/-/merge_requests/209.
 - It allows local-prefix (e.g. jhbuild) builds of GLib to build in a
   custom prefix while still interacting with system services using the
   system-wide `/run` directory. To do so, pass `-Druntime_dir=/run` to
   meson configure.

As documented in the `NEWS` file in
https://gitlab.freedesktop.org/dbus/dbus/-/merge_requests/209, it’s only
valid to use `/run` – rather than `/var/run` – for D-Bus if the two
paths are interoperable. i.e. `/var/run` should be a symlink to `/run`,
and the D-Bus daemon should be configured to put its socket there.

This commit deliberately doesn’t introduce a special `system_socket`
configure option for specifying where the D-Bus system socket lives, as
that would only be useful for a distribution which sets `runstatedir` to
something other than `/var/run` or `/run`, which seems unlikely. We
could add such an option in future, though, if a distribution comes
forward with such a requirement.

This reverts commit 7e3e591d43.

The freedesktop SDK, which is used by gnome-build-meta, only has Meson
0.63. Bumping GLib’s Meson dependency to 0.64 means that, at the moment,
GLib is not buildable in gnome-build-meta and hence can’t be tested in
nightly pipelines against other projects, etc.

That’s bad for testing GLib.

It’s arguably bad that we’re restricted to using an older version of
Meson than shipped by Debian Testing, but that’s a separate discussion
to be had.

Revert the Meson 0.64 dependency until the freedesktop SDK ships Meson ≥

GLib is not buildable in gnome-build-meta and hence can’t be tested in
nightly pipelines against other projects, etc.

That’s bad for testing GLib.

It’s arguably bad that we’re restricted to using an older version of
Meson than shipped by Debian Testing, but that’s a separate discussion
to be had.

Revert the Meson 0.64 dependency until the freedesktop SDK ships Meson ≥
0.64. This also means reverting the simplifications to use of
`gnome.mkenum_simple()`.

756b424cce meson: Use gnome.mkenum_simple()
Meson now uses find_program() to get glib-mkenum from glib instead of
from system. That was already fixed at least in >=0.60 which is our
current minimum requirement.

fd27c8dc6e tests: Add G_TEST_OPTION_ISOLATE_DIRS to almost all gdbus tests
This is a spiritual follow-up to commit 8cff531520, which
added `G_TEST_OPTION_ISOLATE_DIRS` to the `gdbus-connection-flush` test
to avoid its D-Bus cookie lock file from being erroneously deleted by
other tests running in parallel.

The same failure mode could affect any of the other D-Bus tests which
connect to a bus. As an easy fix, enable `G_TEST_OPTION_ISOLATE_DIRS`
for all of them.

The only test it’s not (yet) enabled for is `gdbus-address-get-session`
as that messes around with `XDG_RUNTIME_DIR` to test finding the session
bus. It might be possible to use `G_TEST_OPTION_ISOLATE_DIRS` with it,
but that would take longer than I have right now.

In any case, the more tests (which try to connect to a bus) that this is
enabled for, the lower the chances of spurious test failure due to them
conflicting over shared resources.

ebfbd9c56a tests: Remove a manual timeout from desktop-app-info test
It sometimes fails under valgrind, and is pointless: if the test is
wedged, it’s better to catch that with the timeout at the level of
`meson test`, which can be tailored (using `-t`) to the test environment
and wrapper.

b836ed5c13 tests: Stop using GMainLoop in actions test
Instead, iterate the `GMainContext` directly. This allows tests on
asynchronously returned values to be done in the actual test function,
rather than a callback, which should make the tests a little clearer.

This introduces no functional changes.

e8c068db50 gnotificationbackend: Fix a GDBusConnection leak
`g_notification_backend_new_default()` adds a reference on
`backend->dbus_connection` (if non-`NULL`), but nothing ever unreffed
that.

Fix that by adding a dispose method.

In practice this is not really a problem, because the notification
backend is held alive by a `GApplication`, which lives as long as the
process. It’ll be a problem if someone is to ever add unit tests for
`GNotificationBackend`s though. So let’s fix it.
