The output from the echo program ends up being outputted with the stdout
from the unit test in some tests. Ensure that the input to the echo
program is therefore a valid TAP comment, rather than garbage, so that
it’s safely ignored by a TAP parser looking at the output from the test.

It seems this script has potentially never worked properly under Python
3. It’s supposed to list all the `_get_type()` functions it can find in
the GIO headers, but since the regex string passed to `re.search()` was
not a Python regex, nothing was matching.
Fix that, and do another few small cleanups to the script.
This makes the `defaultvalue` test not skip all the types.

This is unlikely to be a bug in practice, as the certificate pointed to
by `root` should have a ref held on it as the issuer of another
certificate in the chain.
However, we can’t guarantee that’s how the `GTlsCertificate`
implementation behaves, so keep a temporary ref on `root` until it’s no
longer needed.

Coverity CID: #1489985
This is a partial revert of commit fa8c7c0da using the approach
suggested (and tested) by Kjell Ahlstedt.
It is intended to be temporary pending a proper dig into what’s causing
the regression, just so we can get the 2.73.1 release out.

Padding numbers with a typical space character doesn't align them well
because it has a different size. Instead, we need to use the "U+2007"
figure (numeric) space that has the same size as a numerical digit.
This is only visible when using the `tnum` font feature that
makes numbers monospace.
Closes#2655
This means we can specify the standard options for testing GLib under
valgrind consistently, so that developers can use `meson test
--setup=valgrind` to run them.
Port the existing valgrind CI to use them (this will not change its
functional behaviour).

As per review comment, this is miscellaneous enough that it could be
forgotten about at release time, but should still be mentioned.
Guarantee it by starting work on that now.
intl is complicated to look up. Some of that complexity now resides in
Meson, since 0.59.0, via a `dependency('intl')` lookup, so use that
instead.
The Meson lookup doesn't include all the checks here, but likewise this
meson.build doesn't include all the checks in Meson. Particularly, the
following are different:
- Meson accurately detects support built into libc, even if that
conflicts with an external library version (which should be detected as
broken and thus not-found, but glib does not do so).
The problem here is that depending on which libintl.h header is first
in the search path, the *gettext symbols may be the libc ABI, or they
may be renamed to libintl_*gettext, then additionally take over the
*gettext names via a macro, in order to invoke the external library
version even on systems where there is a libc builtin. This means that
checking for `cc.has_function()` correctly reports that there is such
a function in libc, but that unfortunately does not mean it is usable,
because source code referencing `ngettext` etc. will expect to be
linked to `libintl_ngettext`.
- glib checks whether the found intl requires pthread, rather than
simply trusting the result of `cc.find_library()` for the external
library case.
Do the heavy lifting by using Meson to check for intl, and select the
correct implementation, but do a post-discovery check if the symbol is
linkable both with/without pthread.
The logic is still a bit hairy, and eventually more of the logic could
be moved into Meson. But it's better than before.
Fixes incorrect detection of intl on musl-based systems (which have a
less capable libc intl), when GNU libintl is installed as an external
library.
iconv is complicated to look up. That complexity now resides in
Meson, since 0.60.0, via a `dependency('iconv')` lookup, so use that
instead.
No effort is made to support the old option for which type of iconv to
use. It was a false choice, because if only one was available, then
that's the only one you can use, and if both are available, the external
iconv shadows the builtin one and renders the builtin one unusable,
so there is still only one you can use.
This meant that when configuring glib with -Diconv=libc on systems that
had an external iconv, the configure check would detect a valid libc
iconv, try to use it, and then fail during the build because iconv.h
belongs to the external iconv and generates machine code using the
external iconv ABI, but fails to link to the iconv `find_library()`.
Meson handles this transparently.
Rather than carrying the copylib around inside GLib, which is a pain to
synchronise and affects our code coverage statistics.
This requires updating the CI images to cache the new subproject,
including updating the `cache-subprojects.sh` script to pull in git
submodules.
It also requires adding `gioenumtypes_dep` to be added to the
dependencies list of `libgio`, since it needs to be build before GVDB as
it’s pulled in by the GIO headers which GVDB includes.

The interface was ready for this API but it was not provided.
So implement this, using a thread that calls the sync API for now.
Add tests.
Helps with: GNOME/glib#157
This documents our existing testing best practices, and tries to explain
some of the rationale around them.
There’s some new policy around performance tests, specifying that they
are good to keep around if they are high quality (so they can be used
again, the effort put into them not thrown away, and the numbers
compared over time) and that they should be runnable automatically to
avoid bitrot.
Everything else just documents existing practice.

Coverity notices the `g_object_unref()` call in `g_object_notify()`, but
not the paired `g_object_ref()` call. It therefore incorrectly assumes
that every call to `g_object_notify()` frees the object. This causes a
lot (hundreds) of false positive reports about double-frees or
use-after-frees.
I can’t find a way to fix this using a model file, so the other options
are:
* Manually mark every report as a false positive and keep updating them
as the code changes over time. This would take a lot of maintainer
effort.
* Comment out the `g_object_ref()`/`g_object_unref()` calls when
running static analysis (but not in a normal production build). This
is ugly, but cheap and shouldn’t impact maintainability much.
So this commit implements option 2.

`GSocketClient` chains its internal `GCancellable` objects to ones
provided by the caller in two places using `g_cancellable_connect()`.
However, it never calls `g_cancellable_disconnect()`, instead relying
(incorrectly) on the `GCancellable` provided by the caller being
short-lived.
In the (valid) situation where a caller reuses one `GCancellable` for
multiple socket client calls, or for calls across multiple socket
clients, this will cause the internal `GCancellable` objects from those
`GSocketClient`s to accumulate, with one reference left each (which is
the reference from the `g_cancellable_connect()` closure).
These `GCancellable` instances aren’t technically leaked, as they will
all be freed when the caller’s `GCancellable` is disposed, but they are
no longer useful and there is no bound on the number of them which will
hang around.
For a program doing a lot of socket operations, this still-reachable
memory usage can become significant.
Fix the problem by adding paired `g_cancellable_disconnect()` calls.
It’s not possible to add a unit test as we can’t measure still-reachable
memory growth before the end of a unit test when everything has to be
freed.

g_object_new_with_custom_constructor needs to handle
freezing notifications in the same way as
g_object_new_internal.
Fixing a bug pointed out by Christian Hergert.
The corner-case we are handling here is that
we don't freeze the notify queue in g_object_init
(because there's no custom ->notify vfunc, but
then we gain a notify handler during instance
init, and instance init also triggers a
notification. Handle this by jit freezing
notification in g_object_notify_by_spec_internal.
Note that this is bad code - instance init really
shouldn't be doing things like this.
Testcase included.
Fixes: #2665
