We are matching `<parameter>` as well as `<para>`, and we
end up with broken XML in case the (expanded) description
starts with `<parameter>`.
Fixes: #2601
We can't exercise precondition check failures if GLib was (inadvisably)
compiled with -Dglib_checks=false, and we shouldn't necessarily exercise
precondition check failures when using QA tools like valgrind, so skip
these tests if run with -m no-undefined.

Previously, these tests would always pass. If the precondition check
failed (as we want it to), the subprocess would exit unsuccessfully;
but if the precondition check wrongly passed, the subprocess would
continue, allocate a nonzero amount of memory, and fail the
g_assert_null(), resulting in the subprocess exiting unsuccessfully
and the test still passing.

On ILP32 platforms, 4 is a valid alignment for g_aligned_alloc(), so
use 2 as our invalid alignment instead.

This allows the controller to explicitly be removed from the bus, in a
way that allows the caller to synchronise with it and know that all
other references to the controller should have been dropped (i.e. after
this method returns, there should be no in-flight D-Bus calls still
holding a reference to the object).
This is needed to be able to guarantee finalisation of the controller in
unit tests (and comparable real-world situations).

Helps: #1190
The resources data is generated for both GCC and MSVC toolchains, even
though we know beforehand which toolchain we're going to compile it for.
By dropping the data duplication we make the generated resources file
faster to compile, especially when dealing with large embedded data,
instead of relying on the C pre-processor to walk the whole file and
discard the branch we're not using.
We only want to include gslist.h here if it was not already included via
including glib.h, as:
* gslist.h should normally be included via glib.h if used outside of
GLib itself.
* This broke Visual Studio builds that use GResources (via
glib-compile-resources.exe) as that would cause the generated code to
include gslist.h directly, which is therefore disallowed.
This can happen if a caller (ab)uses `execve()` to execute a gtest
process with an empty `argv` array. `g_test_init()` has to gracefully
handle such a situation.
Fix a few problem areas in the code, and add a simple test which checks
that `g_test_init()` doesn’t crash when called with an empty `argv`.

While `execve()` might allow (probably malicious) users to execute a
program with an empty `argv` array, gspawn does not. It’s not actually
possible, as the path to the binary to execute is not specified
separately from the argument array.
Explicitly document and encode that in preconditions.

It is not possible for `g_shell_parse_argv()` to return an empty `argv`
array. Make that clear in the documentation and add some assertions to
encode it explicitly in the code.

There shouldn’t be any issues here with empty argv arrays since an empty
`Exec=` line is already checked for. Encode that explicitly with an
assertion.

This won’t really affect anything, but we might as well fix them to not
crash if called with an empty `argv` by someone (ab)using `execve()`.
Signed-off-by: Philip Withnall <pwithnall@endlessos.org>
While it’s not usual, it is possible for applications to be called with
an empty `argv` by a process (ab)using `execve()`. Modify the
`GApplication` code example to handle that possibility, so that anyone
copying the example isn’t introducing a bug into their program
immediately.
