tg2: move routing mapper initialization from RootController class definition time to instantiation time
Things happened to work before, despite unfortunate code executation at import
time. TurboGears 2.4 changed something, so actual serving works, but pytest
fails with:
collecting ...
...
data/env/lib/python2.7/site-packages/_pytest/config/__init__.py:463: in _importconftest
raise ConftestImportFailure(conftestpath, sys.exc_info())
E ConftestImportFailure: (local('.../kallithea/tests/conftest.py'), (<type 'exceptions.KeyError'>, KeyError('paths',), <traceback object at 0x7fb6679030e0>))
or more useful, if raising the real exception instead of obfuscating with ConftestImportFailure:
...
kallithea/tests/conftest.py:15: in <module>
from kallithea.controllers.root import RootController
kallithea/controllers/root.py:29: in <module>
class RootController(RoutedController, BaseController):
kallithea/controllers/root.py:31: in RootController
mapper = make_map(config)
kallithea/config/routing.py:32: in make_map
rmap = Mapper(directory=config['paths']['controllers'],
data/env/lib/python2.7/site-packages/tg/configuration/tgconfig.py:28: in __getitem__
return self.config_proxy.current_conf()[key]
E KeyError: 'paths'
_importconftest <_pytest.config.PytestPluginManager object at 0x7f20c770a3d0> .../conftest.py
In this example, in RootController, the global config object is at this time just:
{'debug': False, 'package': None, 'i18n.lang': None, 'tg.strict_tmpl_context': True, 'tg.app_globals': None}
Solved by moving the mapper initialization to __init__.

=====================
Repository statistics
=====================
Kallithea has a *repository statistics* feature, disabled by default. When
enabled, the amount of commits per committer is visualized in a timeline. This
feature can be enabled using the ``Enable statistics`` checkbox on the
repository ``Settings`` page.
The statistics system makes heavy demands on the server resources, so
in order to keep a balance between usability and performance, statistics are
cached inside the database and gathered incrementally.
When Celery is disabled:
On each first visit to the summary page a set of 250 commits are parsed and
added to the statistics cache. This incremental gathering also happens on each
visit to the statistics page, until all commits are fetched.
Statistics are kept cached until additional commits are added to the
repository. In such a case Kallithea will only fetch the new commits when
updating its statistics cache.
When Celery is enabled:
On the first visit to the summary page, Kallithea will create tasks that will
execute on Celery workers. These tasks will gather all of the statistics until
all commits are parsed. Each task parses 250 commits, then launches a new
task.
