This change favors `python2` over `python3` by reversing the try/except order.
Untested in `python3`, as most Django packages are not yet `python3`-compatible.
Works in `python2`, `Django 1.5.4`, `gunicorn 18.0`.
When running `gunicorn` in python 2, if a django model doesn't validate, the `gunicorn` will fail to display informative error messages about your model and instead complain about `str`/`unicode`:
Django was falsely accused of [this bug](https://code.djangoproject.com/ticket/20185)
Apache will log %D microseconds over 1 million for requests that take over a second, this change sync's that access log behavior since the formatting seems to be based on that. So a request that takes 1 second and 30 milliseconds will have 1000030 for this atom.
This pull request also adds a %L atom for decimal seconds for a quick human-readable latency number. In the above example it would output 1.000030 to the log.
gunicron_paster, gunicorn_django and other hacks are deprecated. This
patch only advertise gunicorn as the standard, stable and well supported
command.
This commit tries to minimize the chance of sending a kill signal
to a process that is not a gunicorn worker by reaping children
as soon as the SIGCHLD is received.
Close#371
"Limits the number of worker processes to 1" hasn't been true since
06a4dc6 (fix one error in gunicorn_paster, global conf was ignored,
2010-06-22), although it was true when the line was added in 3c7d532
(Large refactor of the documentation and website, 2010-05-22).
"changes some error handling that's sent to clients" hasn't been true
since feb86d3 (don't display the traceback in the HTTP response,
2013-09-27).
The only remaining actions that --debug had were disabling --preload
and hiding debug-level config logging. The former seems useless (just
disable --preload directly) and the latter at doesn't seem useful
enough for a new setting (just turn down --log-level). With this
commit, --preload always works and you always get debug-level config
logging.
I left a stub Debug entry in gunicorn.config, which we can leave in
place while folks convert any gunicorn scripts and configurations to
drop --debug. When the time comes, we can just remove that entry. I
also the boolean-config tests to use --preload, since that will still
be around after we remove the dummy Debug entry.
Fixes#700.
