This test assumes that pcre2 is not provided by a subproject, so force
it to be that. Explicitly allow fallback in the next check (although
it's implied already).
When printing a `GVariant`.
This introduces no functional changes, but should speed things up a
little bit when printing out arrays.

`search_token` cannot be `NULL` at this point (guaranteed by all the
current call sites of `desktop_file_dir_unindexed_search()`), so remove
an unnecessary `NULL` check.
Add an assertion to make the nullability clear.

If the port is not specified, then a default port should be assumed.
This is how everybody expects URIs to work and it's how GProxyResolver
should work too.
We already have lots of tests to ensure this works as expected; however,
the documentation currently does not allow it. Change the documentation
to match reality.
Fixes#2832
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"

If a variant is trusted, that means all its children are trusted, so
ensure that their checked offsets are set as such.
This allows a lot of the offset table checks to be avoided when getting
children from trusted serialised tuples, which speeds things up.
No unit test is included because this is just a performance fix. If
there are other slownesses, or regressions, in serialised `GVariant`
performance, the fuzzing setup will catch them like it did this one.
This change does reduce the time to run the oss-fuzz reproducer from 80s
to about 0.7s on my machine.

When dereferencing the first entry in the offset table for a tuple,
check that it doesn’t fall outside the bounds of the variant first.
This prevents an out-of-bounds read from some non-normal tuples.
This bug was introduced in commit 73d0aa81c2.
Includes a unit test, although the test will likely only catch the
original bug if run with asan enabled.

This can cause a `NULL` dereference on the next line if there is no
`TypeNode` for `iface_type`, for example if `iface_type ==
G_TYPE_INVALID`.
Unlikely, but possible since this API is public.

musl doesn’t define them itself, presumably because they’re not defined
in POSIX. glibc does define them. Thankfully, the values used in glibc
match the values used internally in other musl macros.
Define the values as a fallback. As a result of this, we can get rid of
the `g_assert_if_reached()` checks in `siginfo_t_to_wait_status()`.
This should fix catching signals from a subprocess when built against
musl.

Substring matches can have too much unwanted results, while prefix
matches is more accurate but cannot handle some special cases, this
commit combines them by adding a match_type member, then sort and group
result with both categories and match types.
For the same category, prefix matched results will be put in the first
group and substring matched results will be put in the second group.
In case we're out of memory we should abort after having printed an error
message, this is similar to crashing but not exactly the same, so ensure
we exit for SIGABRT and not because of a SIGSEV.
We use a test wrapper to ensure that both the exit code and the stderr
match what we expected.
During tests in which we are isolating directories, we may still create
temporary files in the global temporary directory without cleaning them
because the value returned by g_get_tmp_dir() is cached when we isolate
the tests directory to the global TMPDIR.
To ensure that we're always isolating the temporary directories, let's
unset the cached temporary directory once we've defined $G_TEST_TMPDIR
so that the returned value of g_get_tmpdir() can be recomputed using the
test isolated temporary directory.
It allows to create a GPtrArray from a null-terminated C array computing its
size and in case performing copies of the its values using the provided
GCopyFunc.
