Add an API to read the summary and description from the .xml schema
files.
This will be used by dconf-editor and gnome-tweak-tool.
This API is a bit heavy -- it parses the XML and builds a table. It
also loads gettext domains for translation. It only does these things
if it is used, however, so it will not impact normal applications.
We store the summary/description in a pair of hash tables on the schema
source (which we have a backref to as of a few commits ago). We can't
use a global table because people might want to request summary and
description from non-default sources. We don't want to use per-schema
tables because we'd have to reparse the directory every time (since we
cannot guess which file a schema may have been in).

Take this private API and make it public along with a boxed type and
ref/unref functions.
Future commits will add accessors with new functionality and some that
allow us to deprecate functions on GSettings itself (such as
g_settings_get_range).

The way we created the global schema list predates
g_settings_schema_source_new_from_directory() and therefore doesn't use
it.
Update it to use that function, removing some code.

This code was added for use by the G_FILE_ATTRIBUTE_THUMBNAIL_IS_VALID
file attribute, but may end up being used elsewhere (e.g. in GVfs) as well.
As it’s dealing with untrusted external files, and the non-trivial PNG file
format, this commit adds several test cases to cover valid and invalid PNG
files.
The security model for the thumbnail verification code is that the user’s
cache directory is untrusted, and potentially any PNG file which is passed
to the verifier has been manipulated arbitrarily by an attacker.
This is a follow-up to commit fe7069749f.
https://bugzilla.gnome.org/show_bug.cgi?id=709898
This indicates whether the thumbnail (given by G_FILE_ATTRIBUTE_THUMBNAIL_PATH)
is valid — i.e. to represent the file in its current state. If
G_FILE_ATTRIBUTE_THUMBNAIL_IS_VALID is FALSE (for a normal _or_ failed
thumbnail) it means the file has changed since the thumbnail was generated, and
the thumbnail is out of date.
Part of checking thumbnail validity (by the spec) involves parsing
headers out of the thumbnail .png so we include some (small) code to do
that in a separate file. We will likely want to copy this code to gvfs
to do the same for GVfsFile.
Heavily based on a patch from Philip Withnall <philip.withnall@collabora.co.uk>
who suggested the feature and designed the API.

It is our intention that memory output streams should operate in two
distinct modes, depending on if a realloc function was provided or not.
In the case that we have a realloc function (resizable mode), we want
the stream to behave as if it were a file that started out empty. In
the case that we don't have a realloc function (fixed-sized mode), we
want the stream to behave as a block device would.
To this end, we introduce two changes in functionality:
- seeking to SEEK_END on a resizable stream will now seek to the end of
the valid data region, not to the end of the allocated memory (which
is really just an implementation detail)
- seeks past the end of the allocated memory size are now permitted,
but only on resizable streams. The next write will grow the buffer
(inserting zeros between).
Some tweaks to testcases were required in order not to break the build,
which indicates that this is an API break, but it seems unlikely that
anyone will be effected by these changes 'in the real world'.
Updates to documentation and further testcases are in following commits.
Based on a patch from Maciej Piechotka <uzytkownik2@gmail.com>.

Introduce the concept of "fixed" vs. "resizable" streams and document
how g_seekable_seek() works for each case.
We don't include g_seekable_is_fixed_size() at this point because we

someone asks for it, however.

D-Bus versions < 1.6.18 (i.e. all current versions) have a bug with the
path_namespace='/' match rule key. It should conceptually match everything,
but actually matches nothing. This results in no property change (or other)

The work-around implemented in GDBusObjectManagerClient is to remove the
path_namespace match key if its value is ‘/’.

Over many years of writing code interacting with subprocesses, a pattern
that comes up a lot is to run a child and get its output as UTF-8, to
put inside a JSON document or render in a GtkTextBuffer, etc.
It's very important to validate at the boundaries, and not say deep
inside Pango.
We could do this a bit more efficiently if done in a streaming fashion,
but realistically this should be OK for now.
We weren't closing the streams after we were done reading or writing,
which is kind of essential. The easy way to fix this is to just use
g_output_stream_splice() to a GMemoryOutputStream rather than
hand-rolling it. This results in a substantial reduction of code
complexity.
A second serious issue is that we were marking the task as complete when
the process exits, but that's racy - there could still be data to read
from stdout. Fix this by just refcounting outstanding operations.
This code, not surprisingly, looks a lot like the "multi" test.
Next, because processes output binary data, I'd be forced to annotate
the char*/length pairs as (array) (element-type uint8). But rather than
doing that, it's *far* simpler to just use GBytes.
We need a version of this that actually validates as UTF-8, that will be
in the next patch.
There are a number of nice things this class brings:
0) Has a race-free termination API on all platforms (on UNIX, calls to
kill() and waitpid() are coordinated as not to cause problems).
1) Operates in terms of G{Input,Output}Stream, not file descriptors
2) Standard GIO-style async API for wait() with cancellation
3) Makes some simple cases easy, like synchronously spawning a
process with an argument list
4) Makes hard cases possible, like asynchronously running a process
with stdout/stderr merged, output directly to a file path

The GApplicationCommandLine DBus implementation currently calls
g_dbus_method_invocation_return_value() in its finalize() implementation
only, relying on the object being destroyed after g_object_unref() is
called on it inside g_application_impl_method_call().
While this is usually fine for C applications, when overriding the
command_line vfunc from language bindings, the binding might add extra
references to the object, which might not be released immediately - e.g.
because they're garbage collected, or possibly even leaked. The same
scenario could happen in a C application that decides to keep a
reference to the passed-in GApplicationCommandLine object.
To ensure the CommandLine DBus method always gets a reply after the
invocation of command_line in the primary instance, explicitly send the
message back before dropping our reference to the object.

Fix up a lot of whitespace issues in this file since we're about to do
some pretty serious rewriting here anyway...
Add some fold markers while we're at it.
Change the search path to be a global array of 'DesktopFileDir' structures and
change the 'get' function to an 'ensure' function.
This is just a straight-up refactor. Future patches will expand the
DesktopFileDir structure.
Add a convenient and race-free method of watching local files from the
GLib worker thread.
Without this, the race-free way to create a monitor that dispatches
events to the worker thread looked something like this:
- dispatch an idle to the worker thread
- from the idle, create the monitor and connect signals
- from the original thread, wait (on a cond?) until the worker thread
has finished setting up the monitor
- read the file that you were monitoring
which is just ridiculously complicated...
To use the new API:
monitor = g_local_file_monitor_new_in_worker ("/path/to/some/file",
G_FILE_MONITOR_NONE,
&error);
g_assert_no_error (error);
g_signal_connect (monitor, "changed", G_CALLBACK (callback), NULL);
g_local_file_monitor_start (monitor);
'callback' will run from the GLib worker thread.
This is the reason that the start() call was introduced in the previous
commit. The backends that don't use the start() call will have a very
thin race between creating the monitor and connecting the signal, but
hopefully they will be fixed soon.
These new APIs will be used (at least) from gdesktopappinfo to watch for
changes in the desktop file directories.

There are some corner cases where using the sync version of read/write
in a thread could cause thread-safety issues. In these cases it's
possible to override the output stream's splice_async() function,
but for input streams one would need to do some acrobatics to
stay thread-safe. Alternatively, some implementations may not even
override their sync read/write functions.
This patch refactors the default splice_async() implementation to
call the sync read and write functions in a thread only when both
async versions are thread-based. When one or both are non-threaded,
it calls the virtual write_async() and read_async() functions of the
involved streams within the same thread.

Refactor g_output_stream_close_async() into itself and an internal

g_cancellable_disconnect will wait until any pending "cancelled"
handlers finish. This is useful because disconnecting a handler can have the
side-effect of freeing data that the cancelled handler may rely on.
Unfortunately, the code used to enforce this synchronization between
"cancelled" handlers and g_cancellable_disconnect will also cause
deadlock if the cancelled handler itself calls g_cancellable_disconect.
Obviously, if g_cancellable_disconnect is explicitly called by a "cancelled"
handler, then the "cancelled" handler is shouldering the responsibility
of not using any data that may be freed by disconnection.
Also, g_cancellable_disconnect can be called in unexpected places by
lower layers in the code (for instance as a result of g_source_destroy).
In practice, this means it's easy for deadlocks to inadvertently crop
up when using "cancelled" handlers.
For these reasons, it would be good to fix the deadlock.
This commit prevents the deadlock by allowing foregoing synchronization,
if a pending "cancelled" handler is in the same thread as the
g_cancellabale_disconnnect call.

In the real_..._async wrapper for GFile.measure_disk_usage, skip the
wrapping of the progress callback in the case that the user gave a NULL
callback to the async function. This is a performance improvement
because the sync version won't have to do continuous sampling of the
clock to issue a call to the wrapper which will then do nothing.
Unfortunately, I made this simplifying assumption when writing the
wrapper, but forgot to actually implement it when making the sync call.
As a result, the wrapper is still called, and invokes the NULL callback,
causing a segfault.
Make sure we pass NULL if the user's callback was NULL.

Virtaal installs a mime package for various .po-like file formats, one
of which has the extension .txt. This causes GLib to report ".txt"

On Windows and OS X, FIONREAD on a UDP socket gets the total number of

GFileMonitor takes great care to sample the thread-default main context
at the time that it is created in order that events can be dispatched to
the correct thread when they come in.
The inotify GFileMonitor implementation uses a global file descriptor
shared between all watches. It has to poll this file descriptor from
somewhere so it arbitrarily picks the default main context.
The problem with that is that the user might not be running it.
Let's use the GLib worker thread for this instead. It's guaranteed to
be running if you need it, and this is exactly the sort of problem it

A previous version of the patch had OnlyShowIn support for desktop file
actions. This was removed from the spec and the patch rewritten, but
this bit of documentation slipped through. Remove it.
For some time, the desktop file specification has supported "additional
application actions". This is intended to allow for additional methods
of starting an app, such as a mail client having a "Compose New Message"
action that brings up the compose window instead of the folder list.
This patch adds support for this with a relatively minimal API.
In the case that the application is a GApplication and DBusActivatable,
desktop actions are translated into GActions that have been added to the
application with g_action_map_add_action(). This more or less closes
the loop on being able to activate an application with an action
invocation (instead of 'activate').

have no readable properties in the introspection, in which case we
should return the empty list in the usual way.
We should certainly _not_ be dispatching to the method call handler of
an interface which has no properties (since it will not be expecting
this).
Add a check to make sure that there is at least one readable property
before assuming that a NULL get_property handler implies that we want to
handle properties asynchronously.
Add a testcase that was failing before the change and works after it.

We don't use # or other forms of links in the section headings.
We also capitalize them and don't put a final period.
This commit corrects several headings to follow these rules.
As it turns out, we have examples of internal functions called
type_name_get_private() in the wild (especially among older libraries),
so we need to use a name for the per-instance private data getter
function that hopefully won't conflict with anything.

We do a bunch of new validity checks for return values in response to

Add some type checking for the values returned from async property

The existing advice in the documentation to "simply" register the
"org.freedesktop.DBus.Properties" interface if you want to handle
properties asynchronously is pretty unreasonable. If you want to handle
this interface you have to deal with all properties for all interfaces
on the path, and you have to do all of the checking for yourself. You
also have to provide your own introspection data.
Introduce a new convention for dealing with properties asynchronously.
If the user provides NULL for their get_property() or set_property()
functions in the vtable and has properties registered then the
properties are sent to the method_call() handler. We get lucky here
that this function takes an "interface_name" parameter that we can set
to "org.freedesktop.DBus.Properties".
We also do the user the favour of setting the GDBusPropertyInfo on the
GDBusMethodInvocation for their convenience (for much the same reasons
as they might want the already-available GDBusMethodInfo).
Add a testcase as well as a bunch of documentation about this new
feature.
https://bugzilla.gnome.org/show_bug.cgi?id=698375
Separate the code for validating a method call from the code for
actually scheduling it for dispatch.
This will allow property Get/Set/GetAll calls to be dispatched to the
method_call handler without duplicating a lot of code.
https://bugzilla.gnome.org/show_bug.cgi?id=698375
We presently do a lot of checks on property sets (signature check,
correct interface, property exists, etc.) from the worker thread before
dispatching the call to the user's thread. The typecheck, however, is
saved until just before calling the user's vfunc, in their thread.
My best guess is that this was done to save having to unpack the value
from the tuple twice (since we don't unpack it until we're just about
the call the user).
This patch moves the check to the same place as all of the other checks.
The purpose of this change is to allow for sharing this check with the
(soon-to-be-introduced) case of handing property sets from
method_call().
This change has a minor side effect: error messages generated by sending
invalid values to property sets are no longer guaranteed to be correctly
ordered with respect to the void returns from successful property sets.
They will instead be correctly ordered with respect to the other error
messages.

When parsing an address, we need to re-set "len" between IPv4 and
IPv6, since WSAStringToAddress() might set it to sizeof(struct sin_addr)
when trying to parse the string as IPv4, even if it fails. Also, we
need to make sure to not pass strings to WSAStringToAddress() that it
will accept but that we don't want it to.
When stringifying an address, we need to clear the sockaddr before
filling it in, so we don't accidentally end up with an unwanted
scope_id or the like.

Previously, g_file_copy() would (on Unix) create files with the
default mode of 644. For applications which might at user request
copy arbitrary private files such as ~/.ssh or /etc/shadow, a
world-readable copy would be temporarily exposed.
This patch is suboptimal in that it *only* fixes g_file_copy()
for the case where both source and destination are instances of
GLocalFile on Unix.
The reason for this is that the public GFile APIs for creating files
allow very limited control over the access permissions for the created
file; one can either say a file is "private" or not. Fixing
this by adding e.g. g_file_create_with_attributes() would make sense,
except this would entail 8 new API calls for all the variants of
_create(), _create_async(), _replace(), _replace_async(),
_create_readwrite(), _create_readwrite_async(), _replace_readwrite(),
_replace_readwrite_async(). That can be done as a separate patch
later.
https://bugzilla.gnome.org/show_bug.cgi?id=699959
Previously, we called g_file_query_info() *again* on the source at the
very end of the copy. This has the lame semantics that if the source
happened to be deleted, we would fail to apply attributes to the
destination. This could even be a security flaw.
This commit changes things so that we query info from the source
*stream* after opening - i.e. on Unix we use the proper fstat() and
friends. That way we operate more atomically.

The freedesktop application specification is largely overlapping the
GLib application D-Bus interface but implementing it will allow for
applications to be launched directly from desktop files, which we want.
We keep the old Gtk interface for compatibility reasons and because it
has some functionality not in the freedesktop spec (Busy state,
CommandLine, etc.).
https://bugzilla.gnome.org/show_bug.cgi?id=699259
Since services are based on D-Bus activation and desktop files are
supposed to be named like the busname for DBusActivatable applications
and since gnome-shell wants wmclass equal to the desktop file name, we
therefore want wmclass equal to the application ID in this case.
wmclass is determined from the prgname, which is otherwise pretty
pointless to set to some random thing in $(libexec) for a D-Bus service,
so set that to the appid.
This means that for D-Bus services, the following things are now all the
same:
- application ID
- prgname
- wmclass property set on all windows
- desktop file name
- well-known bus name
There are not many applications running as D-Bus services at present so
this shouldn't impact anybody except for gnome-clocks (where this change
will be fixing a bug) and gnome-terminal.

OS X's getaddrinfo() only supports IPv6 scope IDs that are interface

In the case that HAVE_DBUS_DAEMON was undefined (as in ostree where glib
is built before D-Bus) this test was failing. Move it inside the
HAVE_DBUS_DAEMON block.
Remove the complications that were introduced in an attempt to make the
gsettings and gschema-compile tests function as installed tests. These
tests are designed (in large part for gsettings and entirely for
gschema-compile) to test the in-tree tools and should not be testing the
system versions.
In the future we may want to move the use of the in-tree tools from the
gsettings testcase into the Makefile and install the resulting files,
allowing this testcase to run against those files, installed.
Perform a substantial cleanup of the build system with respect to
building and installing testcases.
First, Makefile.decl has been renamed glib.mk and substantially
expanded. We intend to add more stuff here in the future, like canned
rules for mkenums, marshallers, resources, etc.
By default, tests are no longer compiled as part of 'make'. They will
be built when 'make check' is run. The old behaviour can be obtained
with --enable-always-build-tests.
--disable-modular-tests is gone (because tests are no longer built by
default). There is no longer any way to cause 'make check' to be a
no-op, but that's not very useful anyway.
A new glibtests.m4 file is introduced. Along with glib.mk, this
provides for consistent handling of --enable-installed-tests and
--enable-always-build-tests (mentioned above).
Port our various test-installing Makefiles to the new framework.
This patch substantially improves the situation in the toplevel tests/
directory. Things are now somewhat under control there. There were
some tests being built that weren't even being run and we run those now.
The long-running GObject performance tests in this directory have been
removed from 'make check' because they take too long.
As an experiment, 'make check' now runs the testcases on win32 builds,
by default. We can't run them under gtester (since it uses a pipe to
communicate with the subprocess) so just toss them in TESTS. Most of
them are passing on win32.
Things are not quite done here, but this patch is already a substantial
improvement. More to come.
This should be the last users that need to be ported.
For some of the oldschool non-gtester-ified tests, we call g_test_init()
from main() because it is necessary in order to use
g_test_build_filename().
Since this feature is so utterly automake-centric, we may as well be
using the same terminology as automake itself (ie: although it's
BUILT_SOURCES, it's DIST_EXTRA, not DISTED).
Also add some comments to the enum explaining that these terms are
really corresponding directly to the automake terms.

Back in the far-off twentieth century, it was normal on unix
workstations for U+0060 GRAVE ACCENT to be drawn as "‛" and for U+0027
APOSTROPHE to be drawn as "’". This led to the convention of using
them as poor-man's ‛smart quotes’ in ASCII-only text.
However, "'" is now universally drawn as a vertical line, and "`" at a
45-degree angle, making them an `odd couple' when used together.
Unfortunately, there are lots of very old strings in glib, and also
lots of new strings in which people have kept up the old tradition,
perhaps entirely unaware that it used to not look stupid.
Fix this by just using 'dumb quotes' everywhere.

It tries to run glib-compile-schemas and glib-mkenums, which
we won't have in the runtime tree.
Anyways it's kind of a dumb test since the best test for
compilation tools is...compiling things, which we already
do frequently.
Although none of the in-tree GSocketConnectable types need it, other
types (like SoupAddress) may find it useful to be able to pass a URI
and a default-port to GProxyAddressEnumerator separately (the same way
you can with GNetworkAddress). So add a default-port property.

This function takes a GIcon, serialises it and sets the resulting
GVariant as the "icon" attribute on the menu item. We will need to add
a patch to Gtk to actually consume this icon.
Also add G_MENU_ATTRIBUTE_ICON.
https://bugzilla.gnome.org/show_bug.cgi?id=688820
Add support for serialising a GIcon to a GVariant and deserialising the
result back to a GIcon.
This solves a number of problems suffered by the existing to_string()
API, primarily these:
- not forcing the icon to be a utf8 string means that we can
efficiently encode a PNG (ie: just give the array of bytes)
- there is no need to ensure that proper types are loaded before using
the deserialisation interface. 'Foreign' icon types will probably
emit a serialised format the deserialises to a GBytesIcon.
We additionally clearly document what is required for being a consumer
or implementation of #GIcon.
Further patches will be required to GdkPixbuf and GVfsIcon to bring
their implementations in line with the new rules (essentially: introduce
implementations of the new serialize() API).
https://bugzilla.gnome.org/show_bug.cgi?id=688820
GBytesIcon is an icon that has a GBytes inside of it where the GBytes

This feature is intended for clients that want to signal a desktop shell
their busy state, for instance because a long-running operation is

The API works in a similar way to g_application_hold and
g_application_release: applications can call g_application_mark_busy()

for clients to use.

We need to close the stream *before* applying the file modes, because

_g_dbus_method_invocation_new is said to allow method_info == NULL,
but will crash inside g_dbus_method_info_ref when the method_info
really is NULL, because g_dbus_method_info_ref does not allow NULL as
parameter. Fixed by checking for NULL in _g_dbus_method_invocation_new
itself.
The leak itself happens because _g_dbus_method_invocation_new stores a
new reference to the method_info without also unreferencing it. Fixed
by adding the missing unref, protected by an if because the pointer
may be NULL.
