galaxy.util.pastescript package

Command for loading and serving wsgi apps taken from PasteScript

Submodules

galaxy.util.pastescript.loadwsgi module

galaxy.util.pastescript.loadwsgi.loadapp(uri, name=None, **kw)

galaxy.util.pastescript.loadwsgi.loadfilter(uri, name=None, **kw)

galaxy.util.pastescript.serve module

galaxy.util.pastescript.serve.difflib = None

A subclass of optparse.OptionParser that allows boolean long options (like --verbose) to also take arguments (like --verbose=true). Arguments must use =.

class galaxy.util.pastescript.serve.BoolOptionParser(usage=None, option_list=None, option_class=<class optparse.Option>, version=None, conflict_handler='error', description=None, formatter=None, add_help_option=True, prog=None, epilog=None)

Bases: optparse.OptionParser

exception galaxy.util.pastescript.serve.BadCommand(message, exit_code=2)

Bases: exceptions.Exception

__init__(message, exit_code=2)

message

Getter for ‘message’; needed only to override deprecation in BaseException.

class galaxy.util.pastescript.serve.NoDefault

Bases: object

class galaxy.util.pastescript.serve.Command(name)

__init__(message, exit_code=2)

message

Getter for ‘message’; needed only to override deprecation in BaseException.

run(args)

pad(s, length, dir='left')

classmethod standard_parser(verbose=True, interactive=False, no_interactive=False, simulate=False, quiet=False, overwrite=False)

Create a standard OptionParser instance.

Typically used like:

class MyCommand(Command):
    parser = Command.standard_parser()

Subclasses may redefine standard_parser, so use the nearest superclass’s class method.

quote_first_command_arg(arg)

There’s a bug in Windows when running an executable that’s located inside a path with a space in it. This method handles that case, or on non-Windows systems or an executable with no spaces, it just leaves well enough alone.

parse_vars(args)

Given variables like ['a=b', 'c=d'] turns it into {'a': 'b', 'c': 'd'}

logging_file_config(config_file)

Setup logging via the logging module’s fileConfig function with the specified config_file, if applicable.

ConfigParser defaults are specified for the special __file__ and here variables, similar to PasteDeploy config loading.

class galaxy.util.pastescript.serve.NotFoundCommand(name)

summary = 'Serve the described application'

description = " This command serves a web application that uses a paste.deploy\n configuration file for the server and application.\n\n If start/stop/restart is given, then --daemon is implied, and it will\n start (normal operation), stop (--stop-daemon), or do both.\n\n You can also include variable assignments like 'http_port=8080'\n and then use %(http_port)s in your config files.\n "

class galaxy.util.pastescript.serve.LazyWriter(filename, mode='w')

Bases: object

File-like object that opens a file lazily when it is first written to.

__init__(filename, mode='w')

open()

write(text)

writelines(text)

flush()

galaxy.util.pastescript.serve.live_pidfile(pidfile)

(pidfile:str) -> int | None Returns an int found in the named file, if there is one, and if there is a running process with that process id. Return None if no such process exists.

galaxy.util.pastescript.serve.read_pidfile(filename)

galaxy.util.pastescript.serve.ensure_port_cleanup(bound_addresses, maxtries=30, sleeptime=2)

This makes sure any open ports are closed.

Does this by connecting to them until they give connection refused. Servers should call like:

import paste.script
ensure_port_cleanup([80, 443])

galaxy.util.pastescript.serve.run(args=None)

galaxy.util.pastescript.serve.invoke(command, command_name, options, args)
