It should be the same +file used by rackup(1) and other Rack launchers, it uses the +*Rack::Builder* DSL. + +# YAHNS OPTIONS +-O client_timeout=SECONDS +: Defines the timeout expiring idle connections. + + Increase this if your application takes longer to run than the + default timeout. Lower this if you run out of FDs. + + Default: 15 (seconds) + +-O listen=ADDRESS[,ADDRESS...] +: Listens on a given ADDRESS. ADDRESS may be in the form of + HOST:PORT or PATH, HOST:PORT is taken to mean a TCP socket + and PATH is meant to be a path to a UNIX domain socket. + Defaults to "0.0.0.0:9292" (all addresses on TCP port 9292). + Multiple addresses may be separated with commas. + +-O stderr_path=PATHNAME +: Allow redirecting $stderr to a given path. Unlike doing this from + the shell, this allows the yahns process to know the path its + writing to and rotate the file if it is used for logging. The + file will be opened with the O_APPEND flag and writes + synchronized to the kernel (but not necessarily to _disk_) so + multiple processes can safely append to it. + + If you are daemonizing and using the default logger, it is important + to specify this as errors will otherwise be lost to /dev/null. + Some applications/libraries may also triggering warnings that go to + stderr, and they will end up here. + + Default: /dev/null if daemonized, controlling terminal if not + +-O stdout_path=PATH +: Same as stderr_path, except for $stdout. Not many applications + write to $stdout, but any that do will have their output written here. + It is safe to point this to the same location a stderr_path. + Like stderr_path, this defaults to /dev/null when daemonized. + + Default: /dev/null if daemonized, controlling terminal if not + +-O worker_threads=INTEGER +: This controls the number of threads for application processing. + Each queue has its own thread pool. Increase this number if your + applications are able to use more threads effectively or if either + (or both) input/output buffering are disabled. Lower this number if + you do not need multi-thread concurrency at all. + + Default: 7 + +# RACKUP OPTIONS +-D, \--daemonize +: Run daemonized in the background. The process is detached from + the controlling terminal and stdin is redirected to /dev/null. + Unless specified via stderr_path and stdout_path, stderr and stdout will + also be redirected to "/dev/null". + +-E, \--env RACK_ENV +: Run under the given RACK_ENV. See the RACK ENVIRONMENT section + for more details. + +-o, \--host HOST +: Listen on a TCP socket belonging to HOST, default is + "0.0.0.0" (all addresses). + If specified multiple times on the command-line, only the + last-specified value takes effect. + This option only exists for compatibility with the rackup(1) command, + use of "-l"/"\--listen" switch is recommended instead. + +-p, \--port PORT +: Listen on the specified TCP PORT, default is 9292. + If specified multiple times on the command-line, only the last-specified + value takes effect. + This option only exists for compatibility with the rackup(1) command, + use of "-l"/"\--listen" switch is recommended instead. + +# RUBY OPTIONS +-e, \--eval LINE +: Evaluate a LINE of Ruby code. This evaluation happens + immediately as the command-line is being parsed. + +-d, \--debug +: Turn on debug mode, the $DEBUG variable is set to true. + +-w, \--warn +: Turn on verbose warnings, the $VERBOSE variable is set to true. + +-I, \--include PATH +: specify $LOAD_PATH. PATH will be prepended to $LOAD_PATH. + The \':\' character may be used to delimit multiple directories. + This directive may be used more than once. Modifications to + $LOAD_PATH take place immediately and in the order they were + specified on the command-line. + +-r, \--require LIBRARY +: require a specified LIBRARY before executing the application. The + \"require\" statement will be executed immediately and in the order + they were specified on the command-line. + +# SIGNALS + +See yahns(1) + +# FILES + +See Rack documentation for a description of the rackup file format. + +# ENVIRONMENT VARIABLES + +The RACK_ENV variable is set by the aforementioned \-E switch. +If RACK_ENV is already set, it will be used unless \-E is used. +See rackup documentation for more details. + +# CONTACT + +All feedback welcome via plain-text mail to <yahns-public@rubyforge.org>\ +No subscription is necessary to post to the mailing list. + +# COPYRIGHT + +Copyright 2013, Eric Wong <normalperson@yhbt.net> and all contributors.\ +License: GPLv3 or later <http://www.gnu.org/licenses/gpl-3.0.txt> + +# SEE ALSO + +yahns(1), yahns_config(5) + +* *Rack::Builder* ri/RDoc +* [Rack RDoc][1] +* [Rackup HowTo][2] + +[1]: http://rack.rubyforge.org/doc/ +[2]: http://wiki.github.com/rack/rack/tutorial-rackup-howto diff --git a/Documentation/yahns.txt b/Documentation/yahns.txt index 0725f49..362851f 100644 --- a/Documentation/yahns.txt +++ b/Documentation/yahns.txt @@ -65,4 +65,4 @@ License: GPLv3 or later <http://www.gnu.org/licenses/gpl-3.0.txt> # SEE ALSO -yahns_config(5) +yahns-rackup(1), yahns_config(5) |
