Spawning 0.8.8 released

Another minor Spawning release cleans up some log messages, the way PYTHONPATH and the location of python are determined, and adds some convenient command-line options for controlling the operation of the server. Here are the release notes:

• Added --access-log-file command line option to allow writing access logs to someplace other than stdout. Useful for redirecting to /dev/null for speed


• Correctly extract the child's exit code and clean up the logging of child exit events.


• Add coverage gathering using figleaf if the --coverage command line option is given. When gathering coverage, the figleaf report can be downloaded from the /_coverage url.


• Add a --max-memory option to limit the total amount of memory spawning will use. If this is exceeded a SIGHUP will be sent to the controller causing the children to restart.


• Add a --max-age option to limit the total amount of time a spawning child is allowed to run. After the time limit is exceeded a SIGHUP will be sent to the controller to cause the children to restart.


• Instead of just passing the PYTHONPATH environment variable through to the children, construct the PYTHONPATH from the contents of sys.path.


• Instead of just trying to run 'spawn' with /usr/bin/env when restarting, just run sys.executable -m spawning.spawning_controller, making it more likely that the controller will run correctly when restarting.


• Add a --verbose option and change the default startup procedure to not log the detailed dictionary of configuration information.
