Kore applications now get a build.conf which may contain different
build flavors. Each flavor can get its own cflags or ldflags.
This was in parts inspired by #106.
A new cli command has been added:
kore flavor
This command allows you to see all flavors and switch between them.
The kore build command now also takes a -v argument which if given
dumps the used CFLAGS and LDFLAGS out to stdout.
For existing applications the build.conf is automatically generated
next time you run kore build or kore run.
Also fixed a bug in the json_yajl example, sneaky change here.
With this framework apps can now send messages between worker processes.
A new API function exists:
int kore_msg_register(u_int8_t id, void (*cb)(const void *, u_int32_t);
This API call allows your app to register a new message callback for a given ID.
You can then send messages on this ID to other workers using:
void kore_msg_send(u_int8_t id, void *data, u_int32_t length);
This framework will interally be used for a few things such as allowing
websocket data to broadcasted between all workers, adding unified caching
and hopefully eventually moving the access log to this as well.
Some internals have changed with this commit:
* worker_clients has been called connections.
* the parent now initializes the net, and event subsystems.
* kore_worker_websocket_broadcast() is dead.
