Listen for "prepare-for-quit" signals from the shell and inhibit
shutdown until all the activities we're tracking are finalized.
Also, add a couple supporting functions:
gboolean e_shell_backend_is_busy (EShellBackend *shell_backend);
void e_shell_backend_cancel_all (EShellBackend *shell_backend);
These will eventually replace mail_msg_active() and mail_cancel_all().
Introduce e_extensible_list_extensions(), which provides extensible
objects access to their own extensions, or a subset of them.
Convert EShellBackend to an abstract EExtension subtype. EShell will
load its extensions with e_extensible_load_extensions(), and then obtain
a list of EShellBackend extensions as follows:
shell_backends = e_extensible_list_extensions (
E_EXTENSIBLE (shell), E_TYPE_SHELL_BACKEND);
Because EShellBackend is abstract, its GType is skipped while traversing
the GType hierarchy to find EShell extensions.
- Collect all shell modules into a new top-level 'modules' directory:
$(top_srcdir)/modules/addressbook
$(top_srcdir)/modules/calendar
$(top_srcdir)/modules/mail
Nothing is allowed to link to these, not plugins nor other modules.
THIS SOLVES BUG #571275 AND OPENS THE DOOR TO PORTING TO MAC OS X.
- Mimic the libevolution-mail-shared library from master (except drop
the "shared" suffix) and have libevolution-mail-importers and all
mail-related plugins link to it.
- Discard the a11y subdirectories and have the files live alongside
their counterpart widgets.
