Jeremy Stanley ec26e2b988 Update ATC and approvers scripts for deliverables
In I2aa729d1b4278743a5e99b41178dc2d11b3e1348 the projects.yaml file
of the governance repo was reorganized to support a new
"deliverables" concept which provides a subgrouping of related repos
under each project team. This requires adjustments in the scripts
consuming that file, specifically email_stats.py and
who-approves.py.

# Description: When run using OpenStack's Gerrit server, this builds
# JSON and YAML representations of repos with information on the
# official owning project team if any, deliverable tags, and groups
# with approve rights listing the members of each along with their
# Gerrit preferred E-mail addresses and usernames when available.
# Rationale: It was done as a demonstration to a representative of a
# foundation member company who requested a list of the "core
# reviewers" for official projects, optionally broken down by
# integrated vs. other. I'm attempting to show that this data is
# already publicly available and can be extracted/analyzed by anyone
# without needing to request it.
# Use: This needs your Gerrit username passed as the command-line
# parameter, found at https://review.openstack.org/#/settings/ when
# authenticated in the WebUI. It also prompts for an HTTP password
# which https://review.openstack.org/#/settings/http-password will
# allow you to generate. The results end up in files named
# approvers.json and approvers.yaml. At the time of writing, it
# takes approximately 6.5 minutes to run on a well-connected machine
# with 70-80ms round-trip latency to review.openstack.org.
# Example:
#
# $ virtualenv approvers
# [...]
# $ ./approvers/bin/pip install pyyaml requests
# [...]
# $ ./approvers/bin/python tools/who-approves.py fungi
# Password:
# [wait for completion]
# $ ./approvers/bin/python
# >>> import yaml
# >>>
# >>> def get_approvers(repos):
# ... approvers = set()
# ... for repo in repos:
# ... for group in repos[repo]['approvers']:
# ... for approver in repos[repo]['approvers'][group]:
# ... approvers.add(approver)
# ... return(approvers)
# ...
# >>> p = yaml.load(open('approvers.yaml'))
# >>> print('Total repos: %s' % len(p))
# Total repos: 751
# >>> print('Total approvers: %s' % len(get_approvers(p)))
# Total approvers: 849
# >>>
# >>> o = {k: v for k, v in p.iteritems() if 'team' in v}
# >>> print('Repos for official teams: %s' % len(o))
# Repos for official teams: 380
# >>> print('OpenStack repo approvers: %s' % len(get_approvers(o)))
# OpenStack repo approvers: 456
# >>>
# >>> i = {k: v for k, v in p.iteritems() if 'tags' in v
# ... and 'release:managed' in v['tags']}
# >>> print('Repos under release management: %s' % len(i))
# Repos under release management: 77
# >>> print('Managed release repo approvers: %s' % len(get_approvers(i)))
# Managed release repo approvers: 245
