1"""Python Daemon Management
2
3This package aids in inspecting and managing daemon processes. A
4program intended for running as a daemon may create PDM listeners, to
5which PDM clients may connect in order to interact with the
6process.

8This package contains the following modules:

10 - srv -- Server module
11 - cli -- Client module
f3bcebd5 12 - perf -- Library for implementing objects for the PERF protocol

14The protocol allows multiple management subprotocols for different
15modes of operation. Currently, the following two management protocols
16are supported.
17
57808152 18 - The REPL protocol implements a simple read-eval-print loop which
6fde0e19
FT
19 accepts arbitrary Python code, executes it in the daemon process,
20 and returns its replies, all in text form. The protocol is simple,
21 generic, and has few failure modes, but is hardly suitable for
f3bcebd5
FT
22 programmatic interaction. See the documentation for L{pdm.srv.repl}
23 and L{pdm.cli.replclient} for further details.

57808152 25 - The PERF protocol is intended for programmatic interaction with the
6fde0e19
FT
26 daemon process. Various Python modules may expose objects that
27 implement one or several of a few pre-defined interfaces that allow
28 for various forms of inspection and management of the program
