This page contains pointers to a collection of idioms which I rely on to accomplish tasks quickly and with predictable results.

verbose python tracebacks: import cgitb; cgitb.enable(format="plain")

verbosity controls on logging: See trac_helper.py

pythonic relations: See my relation module and Alloy (which was my inspiration, though I've made nothing more than a poor knockoff).

relational error logging: See trac_helper.py and collect-pkgs.py.

email-based error reporting: See email_warnings.py.

pdb: from pdb import set_trace as debug ... debug()

rpm makefiles: See rpm-packaging as well as individual projects like olpc-netutils along with my Fedora packaging bibliography.

pymeta parser-based controllers: triagebot is based on a model-view-controller architecture where the controller object is assembled at runtime based on data collected with a metaclass.; pymeta makes it easy to pick the right response to complicated input.

python gdb macros: http://wiki.python.org/moin/DebuggingWithGdb

python memory profiling: guppy + Tomeu's memory leak testing writeup.

tree-based python context management: puritan's main.py and contexts.py

custom dbus decorators: sds stub

ipython for exploring interprocess communication: IPython is wonderfully helpful for exploring xml-rpc and dbus interfaces.

code to make pylint happy: rainbow's inject.py can be automatically checked for many errors by pylint because it passes all data explicitly through function calls.

C error handling: nss-rainbow uses a dash of code-generation and a lot of convention to be very consistent about error detection and handling.

C warning flags & Makefile tips: nss-rainbow's Makefile gets a number of things right, though it can still be improved in several ways.

scripts for user creation: provision users on new machines in a scripted fashion.

program with git: Puritan and other parts of our build system show some silly things you can do with git if you are so inclined.

localize shell code: xs-upserv - just for kicks: a localized Makefile
