Namespaces and tools

lib/utils

python utilities to be used as libraries

• fancylogger: an extention of the default python logger designed to be easy to use and have a couple of fancy features.

• custom specifiers for mpi loggin (the mpirank) with autodetection of mpi

• custom specifier for always showing the calling function's name

• rotating file handler

• a default formatter.

• logging to an UDP server (logdaemon.py f.ex.)

• easily setting loglevel

• daemon.py : Daemon class written by Sander Marechal (http://www.jejik.com) to start a python script as a daemon.

• missing.py: Small functions and tools that are commonly used but not available in the Python (2.x) API.

• cache.py : File cache to store pickled data identified by a key accompanied by a timestamp. (moved to vsc-utils)

• generaloption.py : A general option parser for python. It will fetch options (in this order) from config files, from environment variables and from the command line and parse them in a way compatible with the default python optionparser. Thus allowing a very flexible way to configure your scripts. It also adds a few other useful extras.

• affinity.py : Linux cpu affinity.

• Based on sched.h and bits/sched.h,

• see man pages for sched_getaffinity and sched_setaffinity

• also provides a cpuset class to convert between human readable cpusets and the bit version Linux priority

• Based on sys/resources.h and bits/resources.h see man pages for getpriority and setpriority

• asyncprocess.py : Module to allow Asynchronous subprocess use on Windows and Posix platforms

• Based on a python recipe by Josiah Carlson

• added STDOUT handle and recv_some

• daemon.py : A generic daemon class by Sander Marechal

• dateandtime.py : A module with various convenience functions and classes to deal with date, time and timezone.

• nagios.py : This module provides functionality to cache and report results of script executions that can readily be interpreted by nagios/icinga.

• run.py : Python module to execute a command, can make use of asyncprocess, answer questions based on a dictionary

• supports a whole lot of ways to input, process and output the command. (filehandles, PIPE, pty, stdout, logging...)

• mail.py : Wrapper around the standard Python mail library.

• Send a plain text message

• Send an HTML message, with a plain text alternative
