[brlcad-news] BRL-CAD Project Statistics for 2008

[Christopher S. M. <br...@ma...>]

Included below are some BRL-CAD project statistics that have been  
tabulated for the past fiscal year, from October 2007 to October  
2008.  It was rather interesting to pull the numbers to see how we  
compare to the previous year, so I thought I'd share with you some of  
the details.  Since, I've not (publicly) done this before, a few  
items are worth commenting on before getting to the results.

First off, I'd like to mention that the statistics are reviewed from  
time to time just as a rough measure for how the project is changing  
from a community perspective and (more importantly) to see ways in  
which we can improve.  As with all lies, damned lies, and statistics,  
the numbers should not be read into too deeply, used out of context,  
or used as a basis to justify anything.  This is mostly just food for  
thought and a brief bout of navel gazing.

That said, on to the report:

Over the past year, there have been more than 175 publicly visible  
changes made to the project averaging a feature change every 2.1 days.

Not included in that count are 110 new formal tracker submissions  
including 28 new feature requests, 7 new support requests, 46 new bug  
reports, and 28 new patch submissions (source code contributions).   
By the end of the year, 128 formal issues were addressed including 18  
feature requests, 9 support requests, 75 bug reports, and 26 patch  
submissions.

Our average formal tracker item age for unresolved formal requests  
increased from 484 days to 517 days.

There have been approximately 280 mailing list messages on the brlcad- 
news, brlcad-users, and brlcad-devel mailing lists.  This is an  
increase by more than 160 messages and more than doubles last year's  
count.  That count does not include the brlcad-commits or brlcad- 
tracker mailing lists.

This year, BRL-CAD participated in the 2008 Google Summer of Code  
(GSoC) with 4 students working on independent projects including a  
new prototype GUI, new primitives, a path tracer renderer, and a  
parametric equation and constraint library.  More details on the GSoC  
projects will be provided later as the projects are fully reviewed  
and integrated.

The new BRL-CAD website came on-line in March 2008 providing a  
content management system, a fully-integrated wiki for community- 
based content editing, integrated news and documentation, and an  
image gallery.  The website is processing more than 1000 raw web  
requests per hour on average with more than 6 million raw http  
requests processed since March 2008.  A detailed analysis has not yet  
been performed.

The source code repository was converted from CVS to Subversion (SVN)  
preserving 24 years of BRL-CAD source code revision history across  
20127 files, 147514 CVS revisions, and 29886 change sets.  There have  
been 3228 commits since the repository was converted to SVN on Dec 31  
2007 averaging approximately 10 commits per day.

There were approximately 220,000 direct downloads of BRL-CAD from our  
project site which is an increase of approximately 15% over 2007.

Cheers!
