Always run the full algorithm for a given mime type before considering
fallback types.
This includes considering installed applications capable of handling a
particular mimetype, even if such an app is not explicitly marked as
default, and there is a default app for a less-specific type.
Specifically, this often helps with cases of installing apps that can
handle a particular subtype of text/plain. We want to take those apps
in preference to a generic text editor, even if that editor is listed as
the default for text/plain and there is no default listed for the more
specific type.
Because of the more holistic approach taken by the algorithm, it is now
more complicated, but it also means that we can do more work while
holding the lock. In turn, that lets us avoid duplicating some strings,
which is nice.

The if-else statement added in commit 9bc3ae9 was missing a '\' after the
'else', causing 'make dist/distcheck' to break with "unexpected
end-of-file" errors.
Fix this-didn't notice this when reviewing that patch. My fault. :|
If g_dbus_message_to_blob() fails at all, it will leak its mbuf. Spotted
by running the gdbus-serialization test under Valgrind — so there is a
justification for leak-free tests after all!
Unlike, say, g_variant_new(), which returns a floating reference.
g_variant_parse() returns a non-floating one, so must always have
g_variant_unref() called on the result.
In path_rule_matches(), the given paths may be of 0-length. Do not
access memory before the array in those case. This is for example
triggered by:
test_match_rule (con, G_DBUS_SIGNAL_FLAGS_MATCH_ARG0_PATH, "/", "", FALSE);
in test_connection_signal_match_rules().
This bug was found thanks to GCC AddressSanitizer.

Without this change, out-of-tree distcheck doesn't get very far.
Similarly, allow *.vcxproj, *.props to be in either the builddir or
the srcdir.
Finally, since I'm touching these lines anyway, eliminate some
useless uses of cat: "cat x | sed 's/foo/bar/' > y" is
equivalent to "sed 's/foo/bar/' < x > y".

Passing an nonsense string for the --dest argument can lead

Make sure error handling on repeated <summary> and <description> is
being done properly, not resulting in glib-compile-schemas throwing a
critical.
https://bugzilla.gnome.org/show_bug.cgi?id=747542
Fix a couple of issues in error handling in glib-compile-schemas.
The first problem is that, in case of repeated <summary> or
<description> tags we were still allocating a GString which was never
being freed (due to the throwing of the error resulting in immediate
termination of the parse).
The second problem is that if the repeated <summary> tag also had
attributes, we would attempt to set the GError twice.
https://bugzilla.gnome.org/show_bug.cgi?id=747542
Bug 747209 introduced an error when multiple <summary> or <description>
tags are found for a single key in a GSettings schema. This check
should have been present from the start, but it was left out because the
schema compiler doesn't include these items in the cache file. Even
still -- part of the schema compiler's job is validation, and it should
be enforcing proper syntax here.
Repeated <summary> and <description> tags are a semi-common problem when
intltool has been misconfigured in the build system of a package, but
it's possible to imagine mistakes being made by hand as well.
The idea is that these problems would be caught during the build of a
package and maintainers would be forced to fix their build systems.
An unintended side-effect of this change, however, is that the schema
compiler started ignoring already-installed schemas that contained these
problems, when rebuilding the cache. This means that the installation
of _any_ application would cause the regeneration of the entire cache,
with these already-installed applications being excluded. Without the
schema in the cache, the application would crash on next startup.
The validation check in the gsettings m4 macro passes --strict to the
compiler, which is not used when rebuilding the cache after
installation. Pass this flag down into the parser and only throw the
error in case --strict was given. This will result in the (desired)
build failure without also causing already-installed apps to stop
functioning.
This means that we will not get even a warning about the invalid schema
file in the already-installed case, but that's fine. There is no sense
spamming the user with these messages when they are already quite fatal
for the developer at build time.

Commit f10b655 removed the inclusion of gasyncresult.h from gdbusproxy.c,
but gdbusproxy.c uses g_async_result_get_source_object(), which caused a
build warning/error. Fix that.
The gdbus GTask port introduced a deadlock because some code had been
using g_simple_async_result_complete_in_idle() to ensure that the
callback didn't run until after a mutex was unlocked, but in the gtask
version, the callback was being run immediately. Fix it to drop the
mutex before calling g_task_return*(). Also, tweak
tests/gdbus-connection to test this.

Add support for copying session data between client connections.
This is needed for implementing FTP over SSL. Most servers use a separate
session for each control connection and enforce sharing of each control
connection's session between the related data connection.
Copying session data between two connections is needed for two reasons:
1) The data connection runs on a separate port and so has a different
server_identity which means it would not normally share the session with
the control connection using the session caching currently implemented.
2) It is typical to have multiple control connections, each of which
uses a different session with the same server_identity, so only one of
these sessions gets stored in the cache. If a data connection is opened,
(ignoring the port issue) it may try and reuse the wrong control
connection's session, and fail.
This operation is conceptually the same as OpenSSL's SSL_copy_session_id
operation.

GTask used a 10-thread thread pool for g_task_run_in_thread() /
g_task_run_in_thread_sync(), but this ran into problems when task
threads blocked waiting for another g_task_run_in_thread_sync()
operation to complete. Previously there was a workaround for this, by
bumping up the thread limit when that case was detected, but deadlocks
could still happen if there were non-GTask threads involved. (Eg, task
A sends a message to thread X and waits for a response, but thread X
needs to complete task B in a thread before returning the response to
task A.)
So, allow GTask's thread pool to be expanded dynamically, by watching
it from the glib worker thread, and growing it (at an
exponentially-decreasing rate) if too much time passes without any
tasks completing. This should solve the deadlocking problems without
causing sudden breakage in apps that assume they can queue huge
numbers of tasks at once without consequences.

This schema compiler was completely ignoring <summary> and
<description> tags. Unfortunately, there are modules out there
who merge translations for these back in, with xml:lang. And
this is giving dconf-editor a hard time. Since this is not
how translations of schemas are meant to be done, just
reject such schema files.
Also add tests exercising the new error handling.

Due to a typo, a rename reported via a pair of delete/create events (due
to the watcher not giving the flag for moves to be paired) was
accidentally reported as being created with the old name instead of the
new name.
Fix that.
We declare the typedefs for GListModel and GListStore in giotypes.h, as
a matter of convention. This is not actually required, since the
typedef is emitted as part of the G_DECLARE_* macros.
The giotypes.h approach is only used to avoid cyclic dependencies
between headers, which is not a problem in this case.
Type redefinition is a C11 feature, and although it was around in some
compilers before then, gcc 4.2.1 (from 2007) is apparently still in wide
use, being the default compiler for OpenBSD.
Eventually, we will probably hit a case where we actually need to
redefine a type, but since we're not there yet, let's back off a bit.
GClosure has been in the "allocate area before the pointer" game since
before we did this with GTypeInstance. At the time that this was done
for GClosure, we didn't have valgrind.h in GLib.
Now that we do, we should add similar valgrind hints as the ones we did
for GTypeInstance. This substantially reduces reports of "possibly
lost" on pretty much any program that makes use of signals.

Our signal handler calls write() on a pipe or an eventfd in order to
deliver the notification. It's unlikely, but this could fail, setting
errno. We even check the case that it fails with EINTR.
If it does set errno, then it has potentially blown away the value or
errno that the preempted code cared about (ie: if the signal arrived
shortly after a system call but before errno was checked).
Wrap the handler with code to save errno.

This WIP patch moves the Windows Directory Monitoring code to the new
GLocalFileMonitor mechanism, and adds file monitoring in the process.
Progress from previous patch:
-File renames are now properly supported, but G_FILE_MONITOR_EVENT_MOVED_IN
and G_FILE_MONITOR_EVENT_MOVED_OUT needs to be investigated, as
ReadDirectoryChangesW() seems to send FILE_ACTION_REMOVED when a file is
moved out of a directory.
-Events are handled for both the long and short (8.3) variants of the
filenames, and files monitored will report changes when it is changed
via its short or long filenames.
Things to be done:
-Perhaps find out about attribute changes in files in a monitored
directory; if a file is monitored, attribute changes are correctly
handled.
-Investigate on G_FILE_MONITOR_EVENT_MOVED_OUT,
G_FILE_MONITOR_EVENT_MOVED_IN, G_FILE_MONITOR_EVENT_PRE_UNMOUNT,
G_FILE_MONITOR_EVENT_UNMOUNTED.
-Investigate on the "boredom" algoritm, and see how we can do it on
Windows.
