This is an automated email from the git hooks/post-receive script.
smcv pushed a commit to branch debian
in repository telepathy-mission-control-6.
commit 2da0807f7a4b6be29b980c95b888452f5a6ddc9b
Author: Xavier Claessens <xavier.claessens at collabora.co.uk>
Date: Thu Nov 7 15:07:56 2013 -0500
Simplify a bit storage API
This is an API break, but we already did some since last release.
This removes mcp_account_storage_commit() because it is redundant with
mcp_account_storage_commit_one (plugin, am, NULL);
This removes mcp_account_storage_owns() because an account is now
owned by one and only one storage plugin and MC now keeps track of
which storage plugin each account comes from.
Finally this adds default implementation on most iface methods to
make read-only plugins easier to implement. Only _get() and _list()
and mandatory.

- *
- * For plugins that only store their accounts set up specifically
- * through them (like the libaccounts/SSO pseudo-plugin,
- * McdAccountManagerSSO), create() will fail as unimplemented,
- * and we'll fall through to the next plugin. Eventually we'll
- * reach the default keyfile+gnome-keyring plugin, or another
- * plugin that accepts arbitrary accounts. When set() is called,
- * the libaccounts/SSO plugin will reject that too, and again,
- * we'll fall through to a plugin that accepts arbitrary
- * accounts.
- *
- * Plugins that will accept arbitrary accounts being created
- * via D-Bus (like the default keyfile+gnome-keyring plugin,
- * and the account-diversion plugin in tests/twisted)
- * should, in principle, implement create() to be successful.
- * If they do, their create() will succeed, and later, so will
- * their set().
- *
- * We can't necessarily rely on all such plugins implementing
- * create(), because it isn't a mandatory part of the plugin
- * API (it was added later). However, as it happens, the
- * default plugin returns successfully from create() without
- * really doing anything. When we iterate through the accounts again
- * to call set(), higher-priority plugins are given a second
- * chance to intercept that; so we end up with create() in
- * the default plugin being followed by set() from the
- * higher-priority plugin. In theory that's bad because it
- * splits the account across two plugins, but in practice
- * it isn't a problem because the default plugin's create()
- * doesn't really do anything anyway.
