DebExpo

Tasks

• Write debian/control
  • Get dependencies
• Files for installing it

Other pylons projects already in the archive?

Sid Install

(in a virtualenv)

• Documentation error:

You should use the ‘devel’ branch:

git checkout devel

that branch doesn't exist

• missing dependent package: iso-codes

• ImportError: cannot import name UnicodeMultiDict
  • https://groups.google.com/forum/?fromgroups#!topic/paste-users/ay_mBvbCxqI
  • Solution (temp): change
    • ../local/lib/python2.7/site-packages/Pylons-1.0-py2.7.egg/pylons/decorators/init.py
    • line from webob.multidict import UnicodeMultiDict
    • to from webob.multidict import MultiDict as UnicodeMultiDict

• ImportError: No module named apt_pkg
  • http://apt.alioth.debian.org/python-apt-doc/library/apt_pkg.html
  • missing dependency: python-apt
    • needs virtualenv --system-site-packages

• AttributeError: languages
  • ./debexpo/lib/base.py
  • the method languages is no longer overloaded in request.
  • the closer method 'accept_language' returns a complex string that needs to be parsed and sorted by "quality"
    • http://docs.pylonsproject.org/projects/pyramid/en/latest/api/request.html?awesome#pyramid.request.Request.accept_language
  • temp solution: user_agent_language = "en" #request.languages00:2

#313271 Lost password feature fails

• https://alioth.debian.org/tracker/index.php?func=detail&aid=313271&group_id=100127&atid=413115

The reset link should activate the account, too.

Well, it actually does remove the activation verification entry there.

Cloning

rsync -a bugs-mirror.debian.org::bts-spool-archive bts-spool-archive
rsync -a bugs-mirror.debian.org::bts-spool-db bts-spool-db

Sampling

• Read all .report files, filter the ones with only one bug on the BTS
• Sample 50% fixed, 50% not-fixed

Criteria

• Expected behavior vs. observed behavior
• Reproducible?
  • Test case?
  • How long it'll take to reproduce it?
• Stack trace?
• Screenshot?
• Error message?
  • Localized error
• Severity
  • Could be done automatically using downgrading?
• Rudeness?
• Missing config files
  • Follow up emails saying "can you send me...?"

Implementation

• From CueZilla
  • Detect itemizations
  • Keyword completeness
    • action items (e.g., open, select, click)
    • expected and observed behavior (e.g., error, missing)
    • steps to reproduce (e.g., steps, repro)
    • build-related (e.g., build)
    • user interface elements (e.g., toolbar, menu, dialog)
  • Attachements
    • Code samples (likely not that important in Debian context)
    • Stack traces
    • Patches
    • Screenshots (using file)
  • Readability (using style)
