- Sharpen the hooks, so that they are called only when needed.
- Make settings live, apply them when they are changed.
- Remove the state saver after events hook, call it directly.
- Remove the settings bookkeeping as the gobject properties.
- Remove the scheduling of default-nodes-changed signal via core.
- WirePlumber Lua now facilitates Lua libraries/modules, utilize this and create
modules. Add some tests around this functionality.
- Create policy-hooks.lua containing all the hooks to find-target events
- Create policy-utils.lua module and push all the policy utility functions to it.
- Create common-utils.lua module and push the common utility functions to it.
- Remove all the above functionality from policy-node.lua and clean it up.
They is really no needed with the new _get() API and the WpSpaJson API. In C,
users can use 'wp_spa_json_parse_{boolean|int|float|string}()' APIs to parse the
WpSpaJson. In Lua, users can just do 'Settings.get(setting, m):parse()'.
We need to use WpSpaJson to parse the values in WpSettings. This is because the
wireplumber configuration is written in JSON, so WpSettings should only hold
JSON values. To fix this, 2 API changes have been done:
- wp_settings_get_int() only accepts gint values, instead of gint64 values. This
is because the WpSpaJson API only parses int values, like spa_json_parse_int().
- wp_settings_get_string() now returns a newly allocated string, this is because
the string needs to be decoded in case it has quotes.
This scheme provides for an orderly execution of hooks as the priorities
are controlled from one single place. Enumeration is defined in such a
way that new items can be added easily.
All the event hooks are changed to get the priorities from this
enumeration.
- Add a new variable "name" in WpEventHook and use it to log all the
hooks(by name) picked up in _push_event(). This gives a clear picture
if hook is registered for a given event.
- Form a name for an event and a chain of events for an event run, log
both of them. This gives a clear picture of the events executed and
order in which they are dispatched.
- Similarly build hooks chain and print it in _source_dispatch(), this
gives a clear picture of the hooks picked and the order in which they
are dispatched.
- Log only the dispatchable(with hooks) events, this de-clutters
the log messages.
While calling async execute closure, take a reference to the WpEvent
object before pushing it to the Lua stack. Otherwise Lua garbage
collector frees it, which leads to invalid memory access.
Add a null check when iterator gets the value to detect the end of the
JSON object, this will ensure the rest of the code that operates on the
value is bypassed.
Still it must be noted that an empty setting screws up the following
settings and behavior is undefined, this is the limiation in the
spa-json parsing.
- Move the endpoints defination to wireplumber.conf under a new section
in the form of two JSON objects, namely endpoints and
endpoints-roles.
- Treat the endpoint objects as settings, for the sake of loading,
parsing and querying.
- m-settings loads the objects and WpSettings parses them as any other
settings.
- Make the following changes in endpoint scripts.
- Get the endpoint settings using the _get_string() API.
- Parse and use the data.
- Remove references to the config/lua
- Remove the endpoints defination in config/lua
- add integer and string version of the APIs,
- Also Refine the APIs, return value to indicate the setting existance
and a new param to return the value of the setting.
- add their lua bindings as well, in lua binding the return value nil
indicates that the setting is not defnied.
- Add corresponding C and lua tests as well.
- Add a few handy debug msgs.
- support loading modules dependent on wireplumber settings in JSON
config.
- load the settings module before parsing wireplumber.components,
so that dependencies can be fetched during parsing.
- access lua scripts are switched to JSON based config and lua configs
are removed.
- settings.c tests conf file loading & parsing, metadata updates,
wpsetttings object creation and its API.
- settings.lua tests the API from lua scripts.
- Add a sample settings.conf file, this file contains sections copied
over from client.conf along with the settings section. Add a file
each for wp side and lua side of scripts.
- Make changes in base test infrastructure to take a custom conf file.
- Enhance the wp_settings_get_instance_api() to be take metadata_name
parameter. So, Wpsetttings is now a singleton instance for a given
metadata file.
- Enhance the m-settings module also to be take metadata_name parameter.
this is handy for lua side of tests as its cumbersome to do this is
lua.
- WpSettings is a singleton object which attaches itself to the core
and registry, it provides a get_instance () for its clients.
- WpSettings provides API to get/set wireplumber settings and rules.
- main.c loads the new object and makes sure it is available for
for all the modules and scripts. This is achieved by introducing
a new activation step.
- Add the lua bindings for get_setting API.
- parse settings from .conf file.
- create "sm-settings" metadata and copy settings as key value pairs
to it.
- put in place "persistent" behavior, control it with a special
setting.
- when persistent behavior is enabled.
- create a state file and update settings to it.
- monitor changes in the metadata and update the settings to state
file.
Add a new signal that gets emitted if any WpLink changes to an error
state. This allows better error handling in cases where e.g. no format
could be negotiated.
