The recently added libmount-based unix mount monitoring may fail when the
device exceeds inotify limits. Let's fallback to the older implementation
in case of the `mnt_monitor_get_fd` function failure. This among others
fixes tracker-miners failures caused by seccomp rules.
Fixes: https://gitlab.gnome.org/GNOME/tracker-miners/-/issues/315
The define for g_utf8_next_char(p) includes a not needed final cast to
(char *). In fact, this cast has the adverse effect of causing a warning
if p is a (const char *) with gcc/clang compiler option -Wcast-qual.
So lets remove the not needed cast and add option -Werror=cast-qual
to glib/tests/utf8-pointer.c which uses g_utf8_next_char().
Now utf8-pointer.c compiles also with compiler option -Werror=cast-qual
and passes all tests.
This is a partial revert and rework of commit
c79575362e, for the `gsettings` script
only (the other completion scripts are fine).
I blindly added quoting to everything shellcheck told me to, without
testing it properly.
As it turns out, the `$schemadir` argument to `gsettings` invocations
was deliberately not quoted, so that it would expand to zero arguments
if unset, and two arguments (`--schemadir /some/path`) if set earlier in
the command-being-completed.
Quoting it meant that it expanded to one argument (the empty string) if
unset, which caused the `gsettings` subcommands to fail, and hence any
further tab completion to fail.
Fix that as suggested on https://www.shellcheck.net/wiki/SC2086 by
turning `schemadir` into an array, which either has zero members if
unset, or two members if set.

As suggested by Ville Skyttä in
https://gitlab.gnome.org/GNOME/glib/-/merge_requests/4012#note_2084405,
make sure to invoke the copy of the command which is being completed
when asking for completions of a given subcommand.
This avoids accidentally invoking any old `gdbus`/`gresource`/etc.

Using the same justification as in
https://gitlab.gnome.org/GNOME/dconf/-/merge_requests/81#note_2083220:
it’s hard to get this right, with error handling, in a way which is
understandable to people reading it, and which both bash and shellcheck
will be happy with.
On the assumption that none of the completions generated by any of these
utilities will include ‘problematic’ characters (ones which would cause
word splitting or globbing in bash), just ignore the shellcheck
warnings. Note that I have not actually closely verified that these
utilities can’t return ‘problematic’ characters.
This means we can enable shellcheck, with fatal warnings, for these
scripts, and hence catch future regressions.
If someone wants to improve the handling of globbing/word splitting in
some/all of these array assignments in future, the shellcheck disables
can be removed.

It's well known that memset may be optimized out by compilers and this
is one of these cases that freebsd CI highlighted.
To prevent this to happen we should use memset_explicit() but that's C23, so
till we don't support that, let's re-implement that ourself
making the compiler not to optimize our memset's.
In theory we could just rely on C11's memset_s, but that's not working
either in freebsd.
In other unix implementations other than linux, sigaltstack can't use a
NULL pointer for old_stack, so let's use SS_DISABLE instead to disable
the alternate stack.
Co-Authored-By: Marco Trevisan <mail@3v1n0.net>
Some applications, toolkits or languages may define an alternative stack
to use for traces. This is for example the case of go.
So, in case an application defines an alternate signal stack, GLib should
use that instead of the default one to receive signals otherwise it may
break the application expectations and write where it's not allowed to.
Several of the assertions in GLib (particularly on hot paths in
`gobject.c`) are protected behind `#if G_ENABLE_DEBUG`. In order for
scan-build to see them, the scan-build CI job needs to make sure that
a debug build is definitely enabled — not just rely on it being
implicitly enabled via the combination of other build options.

When piecewise validating the offset table for a variable sized array,
it’s possible that the offset table (`offsets.array`) won’t actually
have been set by `gvs_variable_sized_array_get_frame_offsets()` iff the
serialised `GVariant` is not in normal form.
Add an additional check to guard against this. This will result in an
empty child variant being returned, as with other error handling paths
in `gvs_variable_sized_array_get_child()`.
This is a true positive spotted by scan-build. Thanks, scan-build.

I’m not sure exactly how this code is supposed to work, so this might
not be the right fix. But there’s definitely a problem here, and it was
spotted by scan-build.
If `param_value_array_validate()` is entered with
`value->data[0].v_pointer == NULL && aspec->fixed_n_elements`, that `NULL`
will be stored in `value_array` too. `value->data[0].v_pointer` will
then be set to a new non-`NULL` array.
A few lines down, `value_array_ensure_size()` is called on
`value_array` – which is still `NULL` – and this results in a `NULL`
pointer dereference.
It looks like `value->data[0].v_pointer` and `value_array` are used
interchangeably throughout the whole of the function, so assign the new
value of `value->data[0].v_pointer` to `value_array` too.
My guess is that `value_array` is just a convenience alias for
`value->data[0].v_pointer`, because the latter is a real mouthful to
type or read.

Spotted by scan-build, an actual true positive result from it, and a
fiendish one too.
If any of the calls to `dupfd_cloexec()` (except the final one) fail,
the remainder of the `duped_source_fds` array would have been left
uninitialised.
The code in `out_close_fds` would have then called `g_clear_fd()` on an
uninitialised FD, with unpredictable results.
