I pushed a few EShell features up to GtkApplication for GTK+ 3.2,
so we can now trim off the redundancies in EShell.
1) GtkApplication has a new "window-added" signal which replaces
EShell's own "window-created" signal.
2) GtkApplication has a new "window-removed" signal which replaces
EShell's own "window-destroyed" signal.
3) gtk_application_get_windows() now returns a list of windows sorted
by most recently focused, replacing e_shell_get_watched_windows().
4) GtkApplication now provides enough hooks to subclasses that we can
remove e_shell_watch_window() and call gtk_application_add_window()
directly.
The EModule, EExtensible and EExtension classes as well as the
e_type_traverse() function have been moved to Evolution-Data-Server's
libebackend library to replace e-data-server-module.c.
Now Evolution-Data-Server modules use the same framework as Evolution.
This is primarily for the GNOME Shell calendar.
If, for example, "evolution --component calendar" is invoked and there
is already an Evolution window opened to the calendar view, present that
window. Otherwise open a new Evolution window to the requested view.
Same behavior applies to all requested views.
With lockdown settings available through GSettings, widgets can handle
lockdown integration themselves without having to use EShellSettings.
Also fixed a few places where printing or save-to-disk actions were
either not properly wired up or not responding to lockdown settings,
but much more work needs done. Attachments, for example, are not
honoring the disable-save-to-disk setting at all.
This too requires the recently-added gsettings-desktop-schemas
dependency.
GApplication calls g_main_loop_quit() immediately when the last window
is destroyed, whereas we do it from an idle callback with an extra ref
on EShell to keep it alive until the idle callback runs. But because
GApplication beats us to the punch, our idle callback never runs and
the EShell reference leaks.
For now, we'll just disable the quit_mainloop() method of GApplication.
If GtkApplication grows a signal equivalent to EShell::window-destroyed,
EShell could drop its window_destroyed() method and let G[tk]Application
handle things normally.
An easy way to broadcast application-wide alerts to shell windows.
These alerts will persist in all current and future shell windows
until responded to (either programmatically or by the user).

With unintrusive error dialogs gone, we can cut some unnecessary bits
out of EActivity.
I'm also adding a new enum property called "state", which is one of:
E_ACTIVITY_RUNNING
E_ACTIVITY_WAITING
E_ACTIVITY_CANCELLED
E_ACTIVITY_COMPLETED
The state of an activity must be explicitly changed. In particular,
when the user cancels an activity the state should be set only after
confirming the operation has been cancelled and not when cancellation
is requested (e.g. after receiving a G_IO_ERROR_CANCELLED, not when
the GCancellable emits "cancelled"). EActivityBar and EActivityProxy
widgets have been updated to make this distinction clearer in the UI.
E_ACTIVITY_WAITING will be used when activities have to be queued and
dispatched in sequence, which I haven't written yet.
EActivity now uses a GCancellable to manage cancellations, instead of
having its own redundant cancellation API. API changes are as follows:
+ e_activity_get_cancellable()
+ e_activity_set_cancellable()
- e_activity_cancel()
- e_activity_is_cancelled()
- e_activity_get_allow_cancel()
- e_activity_set_allow_cancel()
EActivity's "cancelled" signal remains, but only as a repeater for
GCancellable::cancelled signals. It should not be emitted directly.
The presence of a GCancellable implies that cancellation is allowed.
EActivity does not create its own default GCancellable, it has to be
given one.
If a CamelOperation (cast as a GCancellable) is given, EActivity will
configure itself to listen for status updates from the CamelOperation
and propagate the information to its own "primary-text" and "percent"
properties.
These changes allowed me to start cleaning up some of the incredibly
convoluted logic in mail-mt.c -- in particular, mail_operation_status()
is completely gone now. mail-mt.c is still in a transitional state --
much more significant changes coming soon.
Given the way the autosave feature was awkwardly bolted on to the
composer, an EExtension seemed like a natural fit. And it helped
clean up some object lifecycle hacks (and bugs).
What we have now is a new module consisting of two EExtensions:
EComposerAutosave extends EMsgComposer and determines when to
kick off an asynchronous autosave operation.
EComposerRegistry extends EShell and offers to restore orphaned
autosave files on startup (which is also asynchronous now).
e-autosave-utils.c holds the actual asynchronous functions and a few
other miscellaneous utility functions.
Source code for the new module lives in /modules/composer-autosave.
e_preferences_window to take factory callbacks and store a reference
to the shell. - This makes start-up substantially faster, particularly
on Atom (eg.).
Remove a number of idle handlers used to create these UIs in the
first instance, cleaning the code.
