This avoids confusion when only the SIP plugin is loaded, but no account
is being used.
For this we introduce two new functions in the abstract CallsProvider class:
`is_modem()` to indicate whether the the provider deals with PTSN telephony and
`is_operational()` which by default simply checks if there any avalaible origins
This includes the following changes:
- Introduce a `providers` hash table to keep track of multiple CallProvider's
and remove the `provider` member
- Remove `calls_manager_get_provider()` and `calls_manager_set_provider()`
in favour of `calls_manager_add_provider()`, `calls_manager_remove_provider()`
and `calls_manager_has_provider()`
- Introduce a `origins` GListStore to keep track of available origins.
`origins` is updated in `items_changed_cb()` when the origins of any
CallsProvider are updated.
- Adapt to changes with respect to `calls_manager_get_origins()`.
- Introduce `origins_by_protocol` hash table to keep track of available origins
per protocol.
- Adjust tests
- We temporarily break country code lookup which was handled previously
with the "default-origin" mechanism. We will add it back to the CallsSettings
class which will provide a better application-wide mechanism.
These are the protocols that the provider plugin may support. The origins
must be queried independently whether or not they support any given protocol.
Example: A SIP origin/account may or may not support the "tel" protocol.
This is in preparation for supporting multiple providers (which are handling
different protocols/URI schemes).
This commit also changes the underlying database schema.
This interface should be implemented by origins which represent an online
account. This means they must have a implement a property representing the
credentials and another representing the account state (online, offline, etc).
This should make sure that we always have 'config.h' available and
should fix issues with flatpak build as seen in #257:
`fatal error: config.h: No such file or directory`
While these macros are not too bad, they will still be removed for the sake
of consistency (no other purism project uses macros this heavily).
Fixes part of #214
This is a bit of a hack to get the country code property hooked up
and will require a rework when multiple provider support is being added.
As the default origin is not being used anywhere else in the code
it's currently not a problem that we're not tracking if the default
origin is being removed.
Additionally test-manager.c needed some adjustment.
Shorten the needed sources from
calls_sources, calls_enum_sources, calls_resources,
wl_proto_sources, wayland_sources,
to
calls_sources
so adding new things such as generated dbus sources doesn't have to
happen in four locations but just one.
