NB you don't need to exclude based on author name. You can simply ask
git for the history, without merges using 'git log --no-merges'

"Merge commits" are created in git history when branches are merged.
They appear as having two parent commits. In OpenStack, our Gerrit
review system automatically creates them when merging into master, so
jenk...@review.openstack.org appears as the author of all of them.

Other projects include those as well (see
https://github.com/apache/incubator-cloudstack/commit/987604216728aa42756c55290495ad55b7449cf3
or
https://github.com/eucalyptus/eucalyptus/commit/df0432f2c5319b1e41122755b701ddab9b802852),
but they appear under the name of the person who manually pushed them.

So I would just go with Jay's suggestion and exclude the
review.openstack.org domain from the domain analysis.

I have look at https://ask.openstack.org/. Yes I will add it as a data source 
in the CY13-Q2 report.

Re: [Openstack] CY13-Q1 Community Analysis — OpenStack vs OpenNebula vs Eucalyptus vs CloudStack

[Qingye Jiang (John)]

Hi Stefano,

Thanks a lot for the feedback. I do agree with you that the so-called 
"participation ratio" is a little bit misleading. I will consider your 
suggestion when doing the CY13-Q2 report. From the OpenNebula mailing list I 
got similar feedbacks, the reason being that the OpenNebula folks can always 
help the user resolve a problem with less email messages. Yes a neutral name 
for the parameter would be much better. Also I do agree that this parameter 
should not be related to the "activeness" of the community members. I will 
remove such judgements from the CY13-Q2 report.

I have not investigate the reasons for the ratio changes for OpenStack and 
CloudStack in their early days. This seems to be an interesting question, and I 
will try to answer that in the CY13-Q2 report.

I saw Jay's suggestion on removing review.openstack.org from the git domain 
analysis. Can you shed some light on how this system works? Is this system 
shadowing more real code contributors?

John

Thanks John, it's always interesting to see comparisons among different 
projects. Although comparisons are hard to make :)


I was looking at the "Participating Ratio", the ratio between “the 
number of  posts” and “the number of topics” that in your post you 
assume it represents the participation rate of an online community.


In your post you argue that "the number of replies to a specific topic 
represents the attention being received, and the depth of discussion for 
that particular topic" basically assuming that a high ratio is always 
better. I disagree with this assumption.


My explanation for decreasing depth of discussions is that the topics 
discussed are less controversial and require less amount of messages to 
close. For OpenStack, patches and changes to code are not discussed on 
the mailing lists anymore but they are debated (sometimes heavily) on 
review.openstack.org instead (which your tools don't capture) while 
afaik cloudstack and other projects seem to review patches on the -dev 
mailing lists. Comparisons across these projects are hard indeed.


You highlight OpenStack's decreasing 'participating ratio' leaving in 
the reader the impression that this must be bad but I don't think that's 
the right conclusion (nor the only one).


I would suggest you to rename "participating ratio" into 
"participating-bickering ratio": slightlgy longer but more neutral; 
lowering "participating-bickering ratio" is neither good nor bad and it 
forces reader to go investigate the causes (and you avoid being 
mis-quoted by some blogger/pundit that doesn't have time to dive deeper 
in the causes).


Have you investigated and found other reasons for why the 
participating-bickering ratio changes so much for OpenStack (especially 
in the early days) and Cloudstack?

Hi Qingye,

It's a very interesting review on the community activity. It would be 
great if you can add a description about your methodology.

[Jay Pipes]

Great work again, John!

One thing I might suggest is to remove the review.openstack.org domain
from the git domain part at the end of the analysis, as it skews the
results significantly (it's the Gerrit patch review tool's email
address, presumably for merge commits.)

Best,
-jay
