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)[source]

Bases: optparse.OptionParser

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

Bases: Exception

__init__(message, exit_code=2)[source]

Initialize self. See help(type(self)) for accurate signature.

property message

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

class galaxy.util.pastescript.serve.NoDefault[source]

Bases: object

class galaxy.util.pastescript.serve.Command(name)[source]

Bases: object


Initialize self. See help(type(self)) for accurate signature.

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.


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.


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


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.LazyWriter(filename, mode='w')[source]

Bases: object

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

__init__(filename, mode='w')[source]

Initialize self. See help(type(self)) for accurate signature.


(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.ensure_port_cleanup(bound_addresses, maxtries=30, sleeptime=2)[source]

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.invoke(command, command_name, options, args)[source]
