twistd

run Twisted applications (TACs, TAPs)

SYNOPSIS

twistd [options]

DESCRIPTION

Read a twisted.application.service.Application out of a file and run it.

OPTIONS

-n, --nodaemon Don't daemonize (stay in foreground). -q, --quiet No-op for backwards compatibility. -p, --profile Run the application under the profiler, dumping results to the specified file. --profiler Specify the profiler to use. Defaults to the 'hotshot' profiler. --savestats Save the Stats object rather than the text output of the pro‐ filer. -b, --debug Run the application in the Python Debugger (implies --nodaemon option). Sending a SIGINT or SIGUSR2 signal to the process will drop it into the debugger. -e, --encrypted The specified tap/aos file is encrypted. --euid Set only effective user-id rather than real user-id. This option has no effect unless the server is running as root, in which case it means not to shed all privileges after binding ports, retaining the option to regain privileges in cases such as spawning processes. Use with caution. -o, --no_save Do not save shutdown state. --originalname Behave as though the specified Application has no process name set, and run with the standard process name (the Python binary in most cases). -l, --logfile Log to a specified file, - for stdout (default: twistd.log). The log file will be rotated on SIGUSR1. -l, --logger A fully-qualified name to a log observer factory to use for the initial log observer. Takes precedence over --logfile and --sys‐ log. --pidfile Save pid in specified file (default: twistd.pid). --chroot Chroot to a supplied directory before running (default: don't chroot). Chrooting is done before changing the current direc‐ tory. -d, --rundir Change to a supplied directory before running (default: .). -u, --uid The uid to run as (default: don't change). -g, --gid The gid to run as (default: don't change). --umask The (octal) file creation mask to apply. (default: 0077 for dae‐ mons, no change otherwise). -r, --reactor Choose which reactor to use. See --help-reactors for a list of possibilities. --help-reactors List the names of possibly available reactors. --spew Write an extremely verbose log of everything that happens. Use‐ ful for debugging freezes or locks in complex code. -f, --file Read the given .tap file (default: twistd.tap). -s, --source Load an Application from the given .tas (AOT Python source) file. -y, --python Use the variable "application" from the given Python file. This option overrides -f. This option implies --no_save. --syslog Log to syslog instead of a file. --version Print version information and exit. --prefix Use the specified prefix when logging to logfile. Default is "twisted". Note that if twistd is run as root, the working directory is not searched for Python modules.

SIGNALS

A running twistd accepts SIGINT for a clean shutdown and SIGUSR1 to ro‐ tate log files.
