That’s what xdgmime uses for zero-sized files (see `XDG_MIME_TYPE_EMPTY`).
Historically, GLib explicitly used `text/plain` for empty files, to
ensure they would open in a text editor. But `text/plain` is not really
correct for an empty file: the content isn’t text because there is no
content. The file could eventually become something else when written
to.
Text editors which want to be opened for new, empty files should add
`application/x-zerosize` to their list of supported content types.
Users who want to set a handler for `application/x-zerosize` on their
desktop should use
```sh
gio mime application/x-zerosize # to see the current handler
gio mime application/x-zerosize org.gnome.gedit.desktop # to set it
```

`HAVE_COCOA` should be used only in the places where we’re actually
depending on the Cocoa toolkit. It should not be used as a general way
of detecting building on a Darwin-based OS such as macOS.
Conversely, there are a few places in the code where we do want to
specifically detect the Cocoa toolkit (and others where we specifically
want to detect Carbon), so keep `HAVE_COCOA` and `HAVE_CARBON` around.

This reverts commit 476e33c3f3.
We’ve decided to remove `G_OS_DARWIN` in favour of recommending people
use `__APPLE__` instead. As per the discussion on #2802 and linked
issues,
* Adding a new define shifts the complexity from “which of these
platform-provided defines do I use” to “which platform-provided
defines does G_OS_DARWIN use”
* There should ideally be no cases where a user of GLib has to use
their own platform-specific code, since GLib should be providing
appropriate abstractions
* Providing a single `G_OS_DARWIN` to cover all Apple products (macOS
and iOS) hides the complexity of what the user is actually testing:
are they testing for the Mach kernel, the Carbon and/or Cocoa user
space toolkits, macOS vs iOS vs tvOS, etc

Some of GLib's unit tests are under an apparently GLib-specific
permissive license, vaguely similar to the BSD/MIT family but with the
GPL's lack-of-warranty wording. This is not on SPDX's list of
well-known licenses, so we need to use a custom license name prefixed
with LicenseRef if we want to represent this in SPDX/REUSE syntax.
Most of the newer tests seem to be licensed under LGPL-2.1-or-later
instead.

In g_proxy_resolver_lookup_async() we have some error validation that
detects invalid URIs and directly returns an error, bypassing the
interface's lookup_async() function. This is great, but when the
interface's lookup_finish() function gets called later, it may assert
that the source tag of the GTask matches the interface's lookup_async()
function, which will not be the case.
As suggested by Philip, we need to check for this situation in
g_proxy_resolver_lookup_finish() and avoid calling into the interface
here if we did the same in g_proxy_resolver_lookup_async(). This can be
done by checking the source tag.
I added a few new tests to check the invalid URI "asdf" used in the
issue report. The final case, using async GProxyResolver directly,
checks for this bug.
Fixes#2799
Similar to g_source_set_static_name, this avoids
strdup overhead for debug-only information in
possibly hot code paths.
We also add a macro wrapper for g_task_set_name that
uses __builtin_constant_p to decide whether to use
g_task_set_name or g_task_set_static_name.
We already set names on most sources, this
one was just forgotten. This lets us set
a static name, and prevents g_task_attach_source
from setting a non-static one.
We need to make sure that such binaries are built and available at test time
or we may fail some tests requiring them (directly or through desktop file).
As per this, and because now generated desktop files are available both
at build and install time, don't skip some tests we were used to, but
actually enforce they are running.
We have some test programs on which some tests depend on, for example
appinfo-test is a tool that is used by the desktop-app-info tests.
So test can now have an 'extra_programs' key where the extra program
names can be included.
This could have been handled manually via 'depends', but this allows
to avoid repeating code and be sure that all is defined when extra
programs targets are checked.
`g_app_info_launch_default_for_uri_async()` has already returned by this
point, so waiting a long time is not really going to help.
Wait for 3× as long as the successful case took, which should allow for
long enough to catch true negatives, with a bit of variance.
On my system, this means waiting for about 14ms, rather than the 100ms
which this previous slept for. This speeds the test up by about 5%.

We were generating .desktop files with different content when installed
tests were enabled, and thus making impossible to test some cases
because there was no built file until installed.
To avoid this, always generate both versions of desktop files while
install only the one containing the install path prefix if needed.
Given that it can be computed using an error-prone strings comparisons it
is better to provide a variable everywhere, so that we don't have the
risk of comparing values that are always false.
We have tests that are failing in some environments, but it's
difficult to handle them because:
- for some environments we just allow all the tests to fail: DANGEROUS
- when we don't allow failures we have flacky tests: A CI pain
So, to avoid this and ensure that:
- New failing tests are tracked in all platforms
- gitlab integration on tests reports is working
- coverage is reported also for failing tests
Add support for `can_fail` keyword on tests that would mark the test as
part of the `failing` test suite.
Not adding the suite directly when defining the tests as this is
definitely simpler and allows to define conditions more clearly (see next
commits).
Now, add a default test setup that does not run the failing and flaky tests
by default (not to bother distributors with testing well-known issues) and
eventually run all the tests in CI:
- Non-flaky tests cannot fail in all platforms
- Failing and Flaky tests can fail
In both cases we save the test reports so that gitlab integration is
preserved.
G_MODULE_SUFFIX is deprecated now because you will get the wrong
results using it most of the time:
1. The suffix on macOS is usually 'dylib', but it's 'so' when using
Autotools, so there's no way to get the suffix correct using
a pre-processor macro.
2. Prefixes also vary in a platform-specific way. You may or may not have
a 'lib' prefix for the name on Windows and on Cygwin the prefix is
'cyg'.
3. The library name itself can vary per platform. For instance, you may
want to load foo-1.dll on Windows and libfoo.1.dylib on macOS. This
is for libraries, not modules, but that is still a use-case that
people use the GModule API for.
g_module_build_path() does take care of (2) on Cygwin, but it
fundamentally cannot handle the possibility of multiple options for
the module name, since it does not do any I/O. Hence, it is also
deprecated.
Instead, g_module_open() has been improved so that it takes care of
all this by searching the filesystem for combinations of possible
suffixes and prefixes on each platform. Along the way, the
documentation for it was also improved to make it clearer what it
does.

This implements https://gitlab.freedesktop.org/dbus/dbus/-/merge_requests/350
for GDBus's server implementation.
Abstract sockets belong to the network namespace instead of the mount
namespace. As a result, mount namespace-based sandboxes (e.g. Flatpak)
cannot restrict access to abstract sockets (and therefore GDBus's
unix:tmpdir= server addresses), at least for applications with network
access permission, which may result in sandbox escapes unless the
application running the GDBus server explicitly check that the connecting
process is not in a sandbox. As of the time of writing, no known
applications using GDBusServer does this.
Fix this by always using non-abstract sockets for unix:tmpdir=, which is
allowed by the DBus specification.
Previously it was marked as failing on macOS, but commit

The implementation of `g_desktop_app_info_launch_uris()` will spawn the
exec file once for each URI unless the desktop file has a placeholder in
its Exec line which supports multiple URIs at once.
The fake terminal doesn’t have such a placeholder, so the fake terminal
script is spawned twice in quick succession, once for each URI. Since it
was making two separate printf calls (one to print the output to the
pipe, and one to terminate it with a newline), it’s possible that two
invocations of the script could interleave their printf calls, resulting
in pipe input along the lines of `URI1 URI2 newline newline` rather than
`URI1 newline URI2 newline`.
This would cause the test to fail.
Fix that by making the script atomic by moving the newline into the
first printf call.

It must only be defined when building libgio. This requires some
workaround to allow include of some gio private headers.
When GIO_COMPILATION is not defined we cannot include individual gio
headers. We workaround that by defining __GIO_GIO_H_INSIDE__ in some
places. Also gdbusprivate.h is not an installed header, so it's fine to
include it directly.
There is currently no `dllimport` attribute on any of our function,
which prevents MSVC to optimize function calls.
To fix that issue, we need to redeclare all our visibility macros for
each of our libraries, because when compiling e.g. GIO code, we need
dllimport in GLIB headers and dllexport in GIO headers. That means they
cannot use the same GLIB_AVAILABLE_* macro.
Since that's a lot of boilerplate to copy/paste after each version bump,
this MR generate all those macros using a python script.
Also simplify the meson side by using `gnu_symbol_visibility : 'hidden'`
keyword argument instead of passing the cflag manually.
This leaves only API index to add manually into glib-docs.xml when
bumping GLib version. That file cannot be generated because Meson does
not allow passing a buit file to gnome.gtkdoc()'s main_xml kwarg
unfortunately.
Otherwise, the build will fail when the toolchain is static-only, even
with -Ddefault_library=static. I talked to a Meson developer in their
IRC channel, who told me that the correct fix was to ensure that
shared_library is only used if default_library != static.

meson test -C _build desktop-app-info -t 0.3 --repeat 80
We may end up in timeout errors, because we are waiting for files that
have been already deleted by other processes.
To avoid this, let's rely on writing the files on `$G_TEST_TMPDIR` env
variable, that is always set and unique, given that we're using the

Those tools are not needed at runtime for typical applications,

The prefix for GMarkupParseFlags enumeration members is G_MARKUP; this
means that G_MARKUP_PARSE_FLAGS_NONE gets split into
GLib.MarkupParseFlags.PARSE_FLAGS_NONE by the introspection scanner.
The `/*< nick=none >*/` trigraph attribute is a glib-mkenum thing, and
does not affect the introspection scanner; it would also only affect the
GEnumValue nickname, which is not used by language bindings to resolve
the name of the enumeration member. Plus, GMarkupParseFlags does not
have a corresponding GType anyway.
The prefix is G_TLS_CERTIFICATE, not G_TLS_CERTIFICATE_FLAGS. Having
G_TLS_CERTIFICATE_FLAGS_NONE leads to a FLAGS_NONE nick in the GType,
and a FLAGS_NONE member name in the introspection data.
Enumeration members should either have the name of the type as their
prefix, or they should all have the same prefix.
The "default flags" enumeration member for GApplicationFlags is
unfortunately named G_APPLICATION_FLAGS_NONE, while every other member
of the same type has a G_APPLICATION prefix. The result is that the nick
name of the enumeration member is "flags-none", and that language
bindings will have to use something like
Gio.ApplicationFlags.FLAGS_NONE.
To fix this API wart, we can deprecate the FLAGS_NONE member, and add a
new DEFAULT_FLAGS.
