This will get the 'user' value from the database (ie: the one that the user has
control over).
Provide a default implementation that chains to ->read(). That will work for
all of our internal backends which don't have a concept of layering or
lockdown.
The delayed backend implments "user value" by returning anything that's
in the changeset (incuding an explicit NULL) or chaining up otherwise.
We will use this for g_settings_get_user_value().

The G_ADD_PRIVATE() macro, and the auto-generated get_instance_private()
internal function, should be used conditionally depending on the maximum
allowed version of GLib, as defined by the GLIB_VERSION_MAX_ALLOWED
pre-processor symbol.
This allows generating code that can be compiled in projects that wish
to use an older API version of GLib through the use of the
GLIB_VERSION_MAX_ALLOWED symbol.

Prevent a crash in the case that gvdb_table_list() returns NULL (ie:
because a schema has no keys).
Stop a memory leak caused by pointlessly stealing keys from a hashtable
(after we quarked them already).
Stop allocating an extra entry at the end of an array for a terminator
(that we never wrote anyway) when all functions using this API refer to
the out-parameter length array.

Ignore the keyfile being deleted (ie: by the user) instead of reporting
it to the application as all values being reverted back to their
originals.

Support the 'extends' attribute that has been supported by the compiler
for a long time by doing three things:
- when creating a schema that extends another schema, lookup that other
schema
- when looking up keys and we can't find them in the schema, check
(recursively) in the 'extends' schema
- when listing all keys in a schema, also visit the extends schemas,
but take care to avoid duplicates caused by overrides
Extend the testsuite to verify that it works.

g_settings_list_schemas() and g_settings_list_relocatable_schemas() are
now deprecated.
This will allow listing off schemas on non-default sources and is a
better fit with the new direction the API is going.
https://bugzilla.gnome.org/show_bug.cgi?id=680838
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).
https://bugzilla.gnome.org/show_bug.cgi?id=668232
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).
https://bugzilla.gnome.org/show_bug.cgi?id=668232
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.

If a broken (or malicious) remote client calls Open or CommandLine
on a GApplication that does not implement those, return a DBus

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
don't know if anyone would require it. This may appear in the future if
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)
signals being forwarded to the D-Bus client.
The work-around implemented in GDBusObjectManagerClient is to remove the
path_namespace match key if its value is ‘/’.
For the upstream D-Bus bug, see:

Move a method from GNotificationBackend into the fdo backend (since it

GNotificationBackend.

g_buffered_input_stream_finalize() is already declared as static in this

Replaced several usages of GError with g_return_val_if_fail() for
developer-only messages. As additional value, it also removes those
messages from the list to translate, simplifying translator's work a
bit.

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
