These keep on taking just longer than 30s on my local machine when run
in parallel with the rest of the tests (i.e. with `ninja test`). Testing
them individually, they do terminate correctly.

Previously, in the case where 'kf' has more than one ref, calling
g_key_file_free(kf) would break it. For example, calling
g_key_file_has_key(kf, ...) would hit the following assertion:
g_hash_table_lookup: assertion 'hash_table != NULL' failed
This is because g_key_file_free() calls g_key_file_clear() which sets
self->groups and other fields to NULL; most lookup functions assume
these fields are non-NULL.
One fix would be to call g_key_file_init() right after
g_key_file_clear() in g_key_file_free(). However, in the case where
there are no other refs to the keyfile, this would mean allocating
many new hash tables which will be immediately destroyed when
g_key_file_unref() removes the last ref. Instead, inline the unref, and
re-initialize the internal state when the keyfile is still alive.
1) Creating a directory with 0666 does not prevent
traversal on Windows (ACL determines the possibility
of traversal, and Windows mkdir() does not translate
permission bits into ACL). Don't do the traversal check on Windows.
2) Creating a file with 0555 also isn't translated into
read-only ACL, Windows sets the read-only attribute instead,
which blocks all changes, including changes to file times.
Add the write permissions on Windows before changing file times.
It turns out that UCRT (which is the C runtime that Visual Studio
uses by default these days) quietly changed the semantics for
stat() functions and its variants. Previously they provided data
for the symlink (if the file queried was a symlink), now they
provide data for the target of the symlink.
glib used to call _wstat64() to get certain stat-ish data about
files, such as st_dev, since it was deemed that computing that
data in glib using custom code would be pointless, as _wstat64()
worked just fine.
With UCRT this is no longer true. This commit drops _wstat64() in
favour of a bunch of custom calls that populate the stat buffer
manually. This way glib correctly gets information about a symlink,
not its target.
The _fstat64() call is still being used, as it does not suffer
from this problem and thus remains untouched.
Even if we're using a prime modulo for the initial probe, our table is
power-of-two-sized, meaning we can set the mask simply by subtracting one
from the size.
Sequential integers would be densely packed in the table, leaving the
high-index buckets unused and causing abnormally long probes for many
operations. This was especially noticeable with failed lookups and
when "aging" the table by repeatedly inserting and removing integers
from a narrow range using g_direct_hash() as the hashing function.
The solution is to multiply the hash by a small prime before applying
the modulo. The compiler optimizes this to a few left shifts and adds, so
the constant overhead is small, and the entries will be spread out,
yielding a lower average probe count.
g_icon_new_for_string() docs states that it should return a single name
when created with a single name. I add a second condition to this case:
the themed icon must not include default fallbacks (i.e. it must not
have been created with `g_themed_icon_new_with_default_fallbacks()`).
Otherwise the return value of `g_icon_new_for_string()` would not
recreate the same icon list when passed to `g_icon_new_for_string()`
(which would be another documentation inconsistency).
g_icon_new_for_string() is now back to old behavior for this specific
case.
I also revert the unit test for this case, and add a new unit test when
using g_themed_icon_new_with_default_fallbacks() with a single name as
well.
Closes#1513.
Currently this function calls `g_warning()` explicitly. It would be
nicer to properly propagate these failure up to the caller that tried to
initialise us.
`read_netlink_messages()` is the callback attached to the netlink socket
(G_IO_IN). It calls `g_socket_receive_message()`. There is a race
condition that if the socket is closed while there is a pending call, we
will try to receive on a closed socket, which fails.
To avoid this, we switch the order of the operations around: first
destroy the source and then close the socket.
This is not a correct way to check if `g_socket_new_from_fd()` failed.
Instead just see if it returned `NULL` itself.
This was preventing the netlink monitor from being initialised.
Closes#1518
All the other initialisation failure paths set a GError, but this one
didn’t. Set a GError to avoid breaking the invariant that returning
FALSE should always have a GError set.

This is a speculative fix for epiphany#533, which we think might be
caused by xdg-desktop-portal not ever being started. This service is
started on-demand, not automatically.
1) Remove the non-Windows-only condition for subdir('tests').
2) Add libiphlpapi, libws2_32 and libsecur32 deps, needed for W32 tests.
3) Remove the -no-undefined argument (gcc doesn't understand it,
it *does* understand -Wl,-no-undefined; either way, the test
compiles without this argument just fine; maybe meson adds it
by itself - you can hardly build shared modules without it).
4) Add or fix a number of includes
5) Disable gdbus-objectmanager tests when building with MSVC
(right now these tests don't work on Windows anyway, so the fact
that MSVC can't even build them properly is irrelevant;
most likely gdbus-codegen needs changes to put _GLIB_EXTERN
before each function)
G_FILE_ATTRIBUTE_DOS_IS_MOUNTPOINT allows mountpoints
(NTFS reparse points with IO_REPARSE_TAG_MOUNT_POINT tag) to
be told apart from symlinks (NTFS reparse points with
IO_REPARSE_TAG_SYMLINK tag), even though both are reported
by glib as "symlinks".
G_FILE_ATTRIBUTE_DOS_REPARSE_POINT_TAG allows the exact
reparse tag value to be obtained by the user. This way
even more exotic reparse points can be identified and
handled by the user (glib itself currently has no code
to work with any reparse points that are not symlinks
or mountpoints).
Extended path prefix looks like "\\?\",
and NT object path prefix looks like "\??\".
Strip them only if they are followed by a character
(any character) and a colon (:), indicating that
it's a DOS path with a drive.
Otherwise stripping such prefix might result in a patch
that looks like a relative path.
For example, "\\?\Volume{GUID}\" becomes "Volume{GUID}\",
which is a valid directory name.
Currently it's up to the user to make sense of such paths.
Partial revert of commit a7a6449f4d.
Checking for the availability of m4 for installing m4 macro files
creates an implicit dependency on m4 even if GLib does not need it; this
prevents building GLib and then installing Autotools in order to build a
project that depends on GLib.
Closes#1520
The existing code was generating code with undefined results that modern compilers warn about:
accounts-generated.c:204:23: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
(GDBusArgInfo **) &_accounts_accounts_method_info_list_cached_users_OUT_ARG_pointers,
It wasn’t being tested. It should behave the same as
g_list_model_get_item(), so write a wrapper for the two.
This brings the code coverage of glistmodel.c up to 100%.

When setting the GListStore:item-type property we need to check the
GType is a GObject (or subclass). There was some explicit code for this,
but when actually testing it and looking at the code coverage, it turns
out that the GObject property type check coming from
g_param_spec_gtype() does everything we want, and the custom
g_critical() can never be hit. So turn it into an assertion.

When running a test as a subprocess and matching its output, it’s very
annoying for GLib to tell you that the output didn’t match your pattern,
*but not actually say what the output was*. Fix that.
