2017-10-19Fixed controller restarting.Valentin Bartenev1-23/+35
Previously, stored configuration wasn't reread on controller process restart, which resulted in segmentation fault.
2017-10-19Filtering process to keep connection.Max Romanov1-0/+7
- Main process should be connected to all other processes. - Controller should be connected to Router. - Router should be connected to Controller and all Workers. - Workers should be connected to Router worker thread ports only. This filtering helps to avoid unnecessary communication and various errors during massive application workers stop / restart.
2017-10-10Optimized application type handling.Valentin Bartenev1-8/+4
2017-10-05Improved applications versions handling.Valentin Bartenev1-11/+4
2017-10-04Port message fragmentation supported.Max Romanov1-8/+28
- Each sendmsg() transmits no more than port->max_size payload data. - Longer buffers are fragmented and send using multiple sendmsg() calls. - On receive side, buffers are connected in chain. - Number of handler calls is the same as number of nxt_port_socket_write() calls. - nxt_buf_make_plain() function introduced to make single plain buffer from the chain.
2017-10-04Introducing process use counter.Max Romanov1-2/+7
This helps to decouple process removal from port memory pool cleanups.
2017-10-04Introducing use counters for port and app. Thread safe port write.Max Romanov1-5/+10
Use counter helps to simplify logic around port and application free. Port 'post' function introduced to simplify post execution of particular function to original port engine's thread. Write message queue is protected by mutex which makes port write operation thread safe.
2017-10-04Using engine memiory pool for port write allocations.Max Romanov1-2/+4
To allow use port from different threads, the first step is to avoid using port's memory pool for temporary allocations required to send data through the port. Including but not limited by: - buffers for data; - send message structures; - new mmap fd notifications; It is still safe to use port memory pool for incoming buffers allocations because recieve operation bound to single thread.

2017-08-04Fixed building by GCC.Igor Sysoev1-1/+1
2017-08-02Listening socket creation and binding operations are passedIgor Sysoev1-0/+197
to the master process.

2017-08-02Runtime processes protected with mutex.Max Romanov1-2/+4
2017-08-02Implicit port read buffer completion.Max Romanov1-3/+0
To disable implicit completion, handler should reset msg->buf field.
2017-08-02Using port rpc in router->master start worker request.Max Romanov1-18/+31
2017-08-02Port RPC interface introduced.Max Romanov1-0/+2
Usage: 1. Register handlers in incoming port with nxt_port_rpc_register_handler(). 2. Use return value as a stream identifier for next nxt_port_socket_write().
