* Use GIO-style async parameters.
* Add mail_folder_cache_note_store_finish().
* Do the bulk of the work in a thread so the logic is more readable.
* Queue multiple calls for the same CamelStore and share the results.
Take a CamelStore and folder name instead of a CamelFolder.
CamelStore and folder name can easily be obtained from either a folder
URI or a CamelFolder instance, and the function is more efficient with
separate parameters.
Replaces mail_folder_cache_get_folder_from_uri().
Returns the CamelFolder for the CamelStore and folder name if available,
or else NULL if a CamelFolder instance is not yet cached. This function
does not block.
Returns whether MailFolderCache has information about the folder
described by the CamelStore and folder name. This does not necessarily
mean it has the CamelFolder instance, but it at least has some meta-data
about it.
You can use this function as a folder existence test.
I considered replacing the "session" property with a "registry"
property, but that just complicates application startup even more.
Fact is, if we have a CamelStore then we can get the CamelSession
and even the ESourceRegistry from it. Kinda dirty, but works.
It goes a little something like this...
camel_service = CAMEL_SERVICE (camel_store);
camel_session = camel_service_get_session (camel_service);
mail_session = E_MAIL_SESSION (camel_session);
registry = e_mail_session_get_registry (mail_session);
Removed functions:
mail_folder_cache_get_session()
Remove mail_folder_cache_service_added() and rely instead on
mail_folder_cache_service_enabled()/disabled(). Despite the function
names the folder cache doesn't actually care about enabled status, it
simply maintains a set of CamelStores to monitor. We should refactor
the folder cache API to better reflect that.
EMailAccountStore always immediately follows a "service-added" signal
emission with either a "service-enabled" or "service-disabled" emission,
which will add or remove the service from the folder cache.
These libraries are bound for E-D-S so they live at the lowest layer of
Evolution for now -- even libeutil can link to them (but please don't).
This is the first step toward moving mail handing to a D-Bus service.
