5c9af3c75c doc: Add some empty lines to unbreak gtkdoc
For some reason gtkdoc thinks g_test_trap_fork() is undefined, unless
some more spacing is added.

40ff475977 Annotate various types and macros as deprecated
These have all been documented as deprecated for a long time, but we’ve
never had a way to programmatically mark them as deprecated. Do that
now.

This is based on the list of deprecations from the reverted commit
80fcb1bc2.

4da8b7b35a gtestutils: Add g_test_summary() to add summary metadata to unit tests
This is a new function along the same lines as g_test_bug(): to allow
developers to annotate unit tests with information about the test (what
it tests, how it tests it) for future developers to read and learn from.

It will also output this summary as a comment in the test’s TAP output,
which might clarify test results.

Includes a unit test.

e5ba5845a1 Revert "headers: Add various missing G_DISABLE_DEPRECATED guards"
This reverts commit 80fcb1bc26.

G_DISABLE_DEPRECATED should never be used by anybody, least of all by
GLib. We have deprecation annotations for the compiler, these days, and
they are much better suited than a macro that makes symbols appear and
disappear. The fact that gtk-doc doesn't understand the deprecation
annotations is a limitation of gtk-doc, and it's gtk-doc that ought to be
fixed.

Commit 80fcb1bc broke GStreamer, which disables old API that was
deprecated before the introduction of the deprecation annotations, but
still uses newly deprecated one, and relies on the deprecation
annotations to do their thing. It also broke libsoup, as it uses
GValueArray in its own API.

e440249bd3 docs: Move some documentation comments from docs.c to their symbols
It would be nice if docs.c eventually went away — it’s more maintainable
for documentation comments to be next to the definition of the symbols
they document.

Move a few from docs.c, based on what I’ve been modifying recently.

The documentation comments are unchanged apart from fixing an argument
name for G_ALIGNOF.

80fcb1bc26 headers: Add various missing G_DISABLE_DEPRECATED guards
As pointed out by gtk-doc, these are all symbols which have been marked
as deprecated, but which aren’t protected by a deprecation guard. We
can’t use G_DEPRECATED_IN_* for them, as they are all non-function
symbols. Instead, wrap them in #ifndef G_DISABLE_DEPRECATED.

In some cases, we also need to wrap one or two functions which use the
deprecated types in G_DISABLE_DEPRECATED too.

8f2365dc8a gtestutils: Call __builtin_undefined() from g_assert_not_reached()
Both GCC and Clang treat this as a hint that the code won’t be reached,
which helps in the cases where they might not have automatically
detected it already.

It doesn’t change any behaviour of the compiled code, other than
allowing the compiler to go off into undefined behaviour.

4a0ce6b458 Add separate definitions of g_assert_[non]null() for C++
In C++ we can use nullptr to ensure g_assert_[non]null() is only called
with pointers. This will introduce build failures in tests that would
have previously compiled, but only in C++, and only for code that
misused these macros. Code using the macros properly will be fine.

This change caught a couple bugs in WebKit's API tests, where I had
accidentally used these functions improperly. E.g. this is now a build
failure in C++:

g_assert_null(webkit_context_menu_get_n_items(menu)); /* Oops! */

Either I wanted to use cmpuint there, or I wanted to use
webkit_context_menu_get_items() to receive a GList* instead.

Another example that will no longer build in C++:

g_assert_null(0); /* Contrived, but 0 is not a pointer! */

13730c27c0 gtestutils: Add XDG directory isolation
Add a new G_TEST_OPTIONS_ISOLATE_XDG_DIRS option for g_test_init() which
automatically creates a temporary set of XDG directories, and a
temporary home directory, and overrides the g_get_user_data_dir() (etc.)
functions for the duration of the unit test with the temporary values.

This is intended to better isolate unit tests from the user’s actual
data and home directory. It works with g_test_subprocess(), but does not
work with subprocesses spawned manually by the test — each unit test’s
code will need to be amended to correctly set the XDG_* environment
variables in the environment of any spawned subprocess.

“Why not solve that by setting the XDG environment variables for the
whole unit test process tree?” I hear you say. Setting environment
variables is not thread safe and they would need to be re-set for each
unit test, once worker threads have potentially been spawned.

ca23acdb24 gtestutils: Bail out of g_test_init() if G_DISABLE_ASSERT is defined
If G_DISABLE_ASSERT is defined, g_assert() is a no-op. Despite it now
being standard practice to *not* use g_assert() in unit tests (use
g_assert_*() instead), a lot of existing unit tests still use it.
Compiling those tests with G_DISABLE_ASSERT would make them silently
no-ops. Avoid that by warning the user loudly.

Note that it’s pretty rare for people to compile with G_DISABLE_ASSERT,
so it’s not expected that this will be hit often.

e5ed410c8c Avoid calling Standard C string/array functions with NULL arguments
glibc string.h declares memcpy() with attribute(nonnull(1,2)), causing
calls with NULL arguments to be treated as undefined behaviour.
This is consistent with ISO C99 and C11, which state that passing 0
to string functions as an array length does not remove the requirement
that the pointer to the array is a valid pointer.
gcc -fsanitize=undefined catches this while running OSTree's test suite.

Similarly, running the GLib test suite reports similar issues for
qsort(), memmove(), memcmp().

dabf662788 testutils: remove internal ABI comment
Some testutils external symbols are marked semi-internals, other
internals. It is not obvious what guarantees these symbols provide.
However, tests are now installable, and require the ABI stability
that glib provides for the rest of the symbols.

In my case, I would like to introduce g_assert* compat code for older
glib versions, and be able to use the so-called "internal" ABI.

I propose this change to the headers comments to explain the stability
guarantees. Removing the "internal" = you must not use this, in favor
of semi-internal = this is not documented.

a6a8750687 Add a way to make assertions non-fatal
When using test harnesses other than gtester (e.g. using TAP),
it can be suboptimal to have the very first failed assertion
abort the test suite.

This commit adds a g_test_set_nonfatal_assertions() that can
be called in a test binary to change the behaviour of most
assert macros to just call g_test_fail() and continue. We
don't change the behavior of g_assert() and g_assert_not_reached(),
since these to assertion macros are older than GTest, are
widely used outside of testsuites, and will cause compiler
warnings if they loose their noreturn annotation.

Also fix the logic of gtestutils's "-p" argument (which is used by the
subprocess tests); previously if you had tests "/foo/bar" and
"/foo/bar/baz", and ran the test program with "-p /foo/bar/baz", it
would run "/foo/bar" too. Fix that and add tests.
