We'll be moving to UID-based directory names across the board for 3.4: $(XDG_DATA_HOME)/evolution/mail/$(UID) $(XDG_DATA_HOME)/evolution/calendar/$(UID) $(XDG_DATA_HOME)/evolution/addressbook/$(UID) ___ evolution-hackers mailing list evolution-hackers@gnome.org To change your list options or unsubscribe, visit ... http://mail.gnome.org/mailman/listinfo/evolution-hackers

Hi there, I know it is muc hlate for input, but anyway, here we go: Am Donnerstag 21 April 2011, um 18:43:27 schrieb Matthew Barnes: > To help smooth the way for the account-mgmt I've made a few improvements > to the CamelSession and CamelService APIs in 3.1.

It was then very easy to recover from the error by just killing my own provider's subdirectory, which was easy to identify (let alone all of the downsides the historic approach may have). Please forgive me for not reading the Camel code here - can one guess from the UID to which account it may belong? What's more, in the current evolution-kolab design for 2.30, we have $(XDG_DATA_HOME)/evolution/mail/$(PROVIDER_NAME)/$(URL) $(XDG_DATA_HOME)/evolution/calendar/$(PROVIDER_NAME)/$(URL) $(XDG_DATA_HOME)/evolution/addressbook/$(PROVIDER_NAME)/$(URL) since we're using CamelStore also in the backends. Hope this will not prove a broken design with the new situation for Camel. Moreover, our pimped IMAPX derivative uses further SQLite databases in addition to the folders.db Camel creates. These are for Kolab metadata and for an offline write cache for Kolab PIM data. The PIM data cache is used in backend context only, while the Kolab folder metadata DB is used by the kolab2 provider run in Evo as well. I hope that changing forth and back the providers for an account will not mess with that. (The Kolab metadata DB is re-created and re-populated in case it is missing, so it should not be problematic during migration.)

Oh sure, http://wiki.meego.com/Architecture/planning/evolution-data-server/email-design has some high level design/architecture of the daemon. It also has details on the way MeeGo app uses it and some task list. But The high level design/architecture of the daemon is up there. -Srini. > > ___ evolution-hackers mailing list evolution-hackers@gnome.org To change your list options or unsubscribe, visit ... http://mail.gnome.org/mailman/listinfo/evolution-hackers

Can you please provide some kind of summary of the design you have, either here on the mailing list or on a wiki page, since as far as I know no one else has a good idea of what you're doing or how it works. I've been trying to get everyone to do this when making large changes, so that no one is working away in secret and suddenly shows up with what they think is a finished product. ___ evolution-hackers mailing list evolution-hackers@gnome.org To change your list options or unsubscribe, visit ... http://mail.gnome.org/mailman/listinfo/evolution-hackers

Let me know if > you see anything amiss. Mostly sounds fine to me as a complete picture, but do remember of the email-factory branch that I'm working on to run mail on EDS. I now expose an API (and some custom bits) over dbus that corresponds to camel's session/store/folder. http://git.gnome.org/browse/evolution-data-server/tree/mail/daemon/e-mail-data-session.xml?h=email-factory http://git.gnome.org/browse/evolution-data-server/tree/mail/daemon/e-mail-data-store.xml?h=email-factory http://git.gnome.org/browse/evolution-data-server/tree/mail/daemon/e-mail-data-folder.xml?h=email-factory It'd be great if you can finalize on the API soon, which can help me move things from 2.32 to master. But for now, I'm mainly on the 2.32 branch to get a stable state of the engine. -Srini. > > ___ > evolution-hackers mailing list > evolution-hackers@gnome.org > To change your list options or unsubscribe, visit ... > http://mail.gnome.org/mailman/listinfo/evolution-hackers > ___ evolution-hackers mailing list evolution-hackers@gnome.org To change your list options or unsubscribe, visit ... http://mail.gnome.org/mailman/listinfo/evolution-hackers
