This series introduces a multi-threaded IPC mechanism called "Simple IPC".
This is a library-layer feature to make it easy to create very long running
daemon/service applications and for unrelated Git commands to communicate
with them. Communication uses pkt-line messaging over a Windows named pipe
or Unix domain socket.
On the server side, Simple IPC implements a (platform-specific) connection
listener and worker thread-pool to accept and handle a series of client
connections. The server functionality is completely hidden behind the
ipc_server_run() and ipc_server_run_async() APIs. The daemon/service
application only needs to define an application-specific callback to handle
client requests.
Note that Simple IPC is completely unrelated to the long running process
feature (described in sub-process.h) where the lifetime of a "sub-process"
child is bound to that of the invoking parent process and communication
occurs over the child's stdin/stdout.
Simple IPC will serve as a basis for a future builtin FSMonitor daemon
feature.
Jeff Hostetler (7):
pkt-line: use stack rather than static buffer in packet_write_gently()
simple-ipc: design documentation for new IPC mechanism
simple-ipc: add win32 implementation
unix-socket: create gentle version of unix_stream_listen()
unix-socket: add no-chdir option to unix_stream_listen_gently()
simple-ipc: add t/helper/test-simple-ipc and t0052
simple-ipc: add Unix domain socket implementation
Johannes Schindelin (3):
pkt-line: (optionally) libify the packet readers
pkt-line: optionally skip the flush packet in
write_packetized_from_buf()
pkt-line: accept additional options in read_packetized_to_strbuf()
