openstack/nova - nova - OpenDev: Free Software Needs Free Tools

nova.flags is no longer needed except to load nova config options shared
across multiple daemons.
This removes nova.flags from the bin programs and makes sure that
nova.flags is imported in nova.config for now.

The flags module will eventually be removed and this is a first step
towards that.

I only just moved logging from nova to common, so behavior should remain the same.

Implements blueprint multi-process-api-service
This is based on Huang Zhiteng's patch.
This patch adds support for running services as multiple processes. This
is primarily intended to be used with the API service as a way to provide
more concurrency than eventlet can sometimes provide.
A SIGTERM or SIGINT signal will cause the parent process to gracefully
terminate the child processes, allowing them to finish processing the
requests currently being processed. The parent will wait for the
children to finish before exiting.

This reverts commit e599636d09
The nova test runner is leaking processes after this change.
Change-Id: Id74463d53f3b7cd749cba293619abef01499b90d

Add multiprocess support for API serivces (EC2/OSAPI_Compute/OSAPI_Volume/Metadata).
2012年06月1日 v7:
 * Add unittest to cover worker recovery, service termination functionality
 in wsgi.py, fix python 2.6 compatibility issue.
 * Modify generate_uid() to introduce per-process seeds in utils.py to avoid
 collisions.
 * Add worker session to nova.conf.sample.
2012年05月21日 v6:
 * Fix 'test_wsgi' unittest error.
2012年04月28日 v5:
 * Add SIGINT handler and fix child-parent race condition when Ctrl+C is
 pressed.
2012年03月31日 v4:
 * Fixed typo, removed debug code.
2012年03月30日 v3:
 * Fixed localization/pep8 error in unittest, add metadata test.
 * nova/wsgi.py:Server: use the greenthread pool created for each process.
 * nova/service.py: remove debug code
2012年03月27日 v2:
 * Fixed unittest error.
 * nova/wsgi.py:Server: Use self._logger to do logging in multiprocess mode.
 * nova/wsgi.py:Server: Move self._pool creation into proper place.
 * code style fix.
2012年03月25日 v1:
 * Modification to nova/service.py and nova/wsgi.py in order to support
 multiprocess (a.k.a. workers) for various API services. If multiprocess
 mode is enabled, (i.e. flags 'APINAME_workers' set to positive numbers),
 corresponding API service will run in target number of process(es). There
 is also a master_worker process spawned for managing all workers (handling
 signal/termination).
 * Add unittest for multiprocess API service, also alter testing/runner.py
 to adopt new unittest.

Implements blueprint cfg-global-object
Replace nova.flags.FLAGS with openstack.common.cfg.CONF.
In future, we can do a s/FLAGS/CONF/ across the codebase.

Implements blueprint remove-old-flagfile
nova-manage can still be used to convert old flagfiles style files
to new .ini files:
$ ./bin/nova-manage config convert --help
Usage: nova-manage config convert <args> [options]
Options:
 -h, --help show this help message and exit
 --infile=<path> old-style flagfile to convert to config
 --outfile=<path> path for output file. Writes configto stdout if not
 specified.
