Re: [Xen-devel] Update on Review Process Modelling Project



Hi everyone,

questions related to the items below are welcome; in particular if anyone suspects the data is wrong. Some if the data is still incomplete, or only covers 2015. Once I have more, I will share.


Best Regards
Lars

Hi Lars,

Current situation of the analysis [1]:

[disclaimer: data are available till August 2015 and in some cases only for 2015, this needs some work, but data should be alright the periods of analysis.]

Activity general overview:
- Evolution of patch series (whole history)
- Evolution of patch series submitters (whole history)
- Evolution of comments (whole history)
- Evolution of people commenting the patch series (in progress)
- Evolution of people reviewing patches (not started)

Time analysis:
- Time to merge (for 2015)
- Time to commit (for 2015)
- Time to re-work a patch (for 2015)
- Cycle time (for 2015)
- Time to first review (whole history)

Backlog analysis:
- Reviews completed (ready to go once we have updated data)
- Reviews active (ready to go once we have updated data)
- Reviews ongoing (ready to go once we have updated data)
- Reviews stalled (ready to go once we have udpated data)

Patch series complexity analysis:
- Number of versions per patch serie (2015)
- Number of touched files and added/removed lines (not started)
- Comments received per patch (whole history)
- Number of patches per patch serie (in progress)

Patch series community:
- Top people sending patches (not started)
- Top people revieweing patches (not started)

Thus, as further work, I need to work on the following steps:

- Update the databases
- Metric: Evolution of people commenting the patch series (in progress)
- Metric: Evolution of people reviewing patches (not started)
- Metric: Number of touched files and added/removed lines (not started)
- Metric: Number of patches per patch serie (in progress)
- Metric: Patch series community metrics.

Regards,
Daniel.
