tests: stabilize Git committer in test_vcs_operations
Git tries to find out name and email in this order:
1. The author can be set e.g. via the `--author` option of `git commit`.
2. If set, the environment variables GIT_AUTHOR_NAME, GIT_AUTHOR_EMAIL,
GIT_COMMITTER_NAME and GIT_COMMITTER_EMAIL are taken.
3. If set, various (global) config files are considered.
4. Unless disabled by the user.useconfigonly config, the names and emails are
inferred from various system sources such as various fields from /etc/passwd,
/etc/mailname and the environment variable EMAIL.
The author can be provided on the command line (1), but that is not possible
for the committer.
It is not an option to modify Git’s configuration files, so the result of (3)
depends on the system the tests run on, which should be avoided. A follow-up
patch will try to instruct Git to not read the system Git configuration files.
(4) is also system-dependent. On some systems, (4) is disabled in the Git
configuration. If enabled, Git will try to infer the committer name from the
gecko field in /etc/passwd, but will fail if it is empty. The previous code
passed the environment variable EMAIL to provide the corresponding email
address.
By passing the names and emails via (2), we can set the author and committer
name and email uniformly and prevent Git from using the system-dependent ways
(3) and (4). This will replace the use of of EMAIL. The environment variables
were introduced in 2005, so there should be no backwards compatibility
problems.
The tests will specify --author explicitly in the cases where the actual name
matters. We just need default values that can be used for committing when we
don't care.
We set it as static defaults to:
Author: test_regular <test_regular@example.com>
Commit: test_admin <test_admin@example.com>
Based on changes and research by Manuel Jacob <me@manueljacob.de>.

=====================
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.
