Only resolve the link at the point that we pull it through the API
rather than at the point that we first are told about it. This reduces
the lifespan of subscriptions and, more importantly, avoids a tricky
reference cycle issue.
Each test needs to remove the sources that it attaches
to the default main context, or else things will work
fine in isolation, but go bad in a full test run.
The code assumes in various places that ':' does not occur
in attribute names. We are a little more strict than that,
and only allow lowercase ASCII, digits and '-'.
There are no public 'exporter' objects, so don't allude to them
in the function names. At the same time, we want to make it clear
that these functions are D-Bus specific.
The new APIs are
g_action_group_dbus_export_start
g_action_group_dbus_export_query
g_action_group_dbus_export_stop
g_menu_model_dbus_export_start
g_menu_model_dbus_export_query
g_menu_model_dbus_export_stop
After questioning the semantics of flush on IRC, it seemed necessary to
clarify what flushing is supposed to do. The Linux man page for fflush()
seemed to cover it perfectly, so I just copied it.
I did not add the "via the underlying write mechanism" part as that in
my opinion is not something subclasses should need to guarantee.
This patch makes GFileMonitor to emit EVENT_CHANGES_DONE_HINT when
EVENT_CREATED is emitted but the file is not opened for writing.
On file moves across different mounted volumes, inotify will always emit
IN_CREATE and IN_CLOSE_WRITE (plus other events).
This translates into GIO's _EVENT_CREATED and _EVENT_CHANGES_DONE_HINT.
On file moves across the same mounted volumes, inotify will emit
IN_MOVED_FROM/IN_MOVED_TO which will be translated into
_EVENT_DELETED/_EVENT_CREATED GIO's side. No _EVENT_CHANGES_DONE_HINT is
emited afterwards.
Under such circumstances a file indexer does not know when actually the
file is ready to be indexed, either waiting too much or triggering the
indexing twice. On small devices it's not advisable.

A g_input_stream_read_async() implementation can't call
g_input_stream_read() on itself directly because it will fail because
the pending flag is already set. So fix that by invoking the vmethod
directly rather than calling the wrapper. Likewise with
GMemoryOutputStream.
Add a test to gio/tests/memory-input-stream.c to catch read_async
failures in the future.
g_file_set_attribute() also permits a NULL value for value_p, and requires it
to be NULL to unset it. Also fix the wrong variable name in the documentation.

This new API allows requesting multiple pieces of information about a
particular action in one go and also simplifies the burden for
GActionGroup implementations -- they need not implement all the separate
APIs now.
This is the ISO C sense of undefined behaviour, in which
works-by-coincidence, critical warning, abort, demons-fly-out-of-your-nose
are all valid implementations.

This was a regression in commit f41178c6c: flush_async_data wasn't
necessarily NULL in the "don't flush" case.
Also move initialization of these variables up so that it's

that each branch gets it right.

We didn't previously flush in a couple of cases where we should have
done:
* a write is running when flush is called: we should flush after it
finishes
* writes have been made since the last flush, but none are pending or

away

This makes it easier to schedule a flush, by putting it on the same code
path as writing and closing.
Also change message_written to expect the lock to be held, since all
that's left in that function either wants to hold the lock or doesn't
care, and it's silly to release the lock immediately before calling
message_written, which just takes it again.

If the user calls flush_sync() with no messages in the queue, but an
async write call pending, then we ought to flush after that async write
returns (although we don't currently do that). If it was an async close
or flush that was pending, there's no need to flush (again) afterwards.
So, we need to distinguish.

The connect_async() calls would never terminated when an application side
proxy was being used. Note we also skip over TLS handshake in this case,
as the application may have to do some proxy handshake before.
The proxy address was not cleared between each attempt. That would lead
to leak or worse, trying to do the proxy handshake on the final
destination address. To make all this safer, I have regroup all the cleanup
where the iterations starts.

Any method that has its prefix'd argument as its first parameter will be
interpreted by introspection as a method. We don't want this, so we need
to swap the first two parameters.
This is strictly redundant now that we can get the ID from the schema
itself. Its only other purpose was to get the schema name from the
set_property() call to the constructed() call and we can avoid that by
doing the schema lookup at the time of the property being set.
Instead of building a reversed linked list by prepending in order and
then reversing it at the end, prepend in reverse by iterating backwards
through the directories (to get a list in-order when we're done).
These functions no longer have anything to do with GSettings itself, so
they should not be in that file anymore.
GSettings still wants direct access to the GSettingsSchemaKey structure,
so put that one in gsettingsschema-internal.h.
We now avoid the per-enumerated-file stat for type and names. We could
improve this further by moving things to the no_stat function, but this
is what the file chooser needs for autocomplete, so I am happy.
We now sort the matchers and remove unnecessary duplicates (like
removing standard:type when we already match standard:*), so that we can
do more complex operations on them easily in later commits.
Include the hostname (or proxy hostname if it was the connection to
the proxy server that failed) in the GError message when
g_socket_client_connect* fail.

Previously, if you created a GUnixInputStream or GUnixOutputStream
from a non-blocking file descriptor, it might sometimes return
G_IO_ERROR_WOULD_BLOCK from g_input_stream_read/g_output_stream_write,
which is wrong. Fix that. (Use the GPollableInput/OutputStream methods
if you want non-blocking I/O.)
Also, add a test for this to gio/tests/unix-streams.
Also, fix the GError messages to say "Error reading from file
descriptor", etc instead of "Error reading from unix" (which was
presumably from a bad search and replace job).

My previous fix for GNOME#662100 was incomplete: it seems that with some
timings, the stream can be closed with an async read in-flight. This
can make the read fail immediately with G_IO_ERROR_CLOSED instead of
becoming cancelled.
This happens reliably on an embedded device, and rarely on my laptop;
repeating the test 100 times in quick succession reliably reproduces
the bug on my laptop.
It seems as though what we really want is to ignore read errors, once
we've established that we want to close the connection anyway - this
means that after asking to close, you're immune to exit-on-close,
which seems like a good rule.
An additional subtlety is that continuing to read after we know we
want to close is still required, otherwise we'll never emit ::closed.
