View source for Dash Project/Commits Explorer

== About ==

The Commits Explorer is a set of [http://dash.eclipse.org/dash/commits/web-app/ webpages] and [http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.dash/dashboard/commits/web-api/?root=Technology_Project web APIs] for querying committer, commit, company, and project data. 

Read about the commits explorer on our [http://eclipse-projects.blogspot.com/2006/05/commits-explorer.html blog], or [http://dash.eclipse.org/dash/commits/web-app/ try it yourself].

The [http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.dash/dashboard/commits/?root=Technology_Project source is available] too, if you want to learn more about the web APIs.

You might also find the database schema useful. If so, it's available in [http://dash.eclipse.org/dash/commits/web-api/schema.php plain text] and [http://dash.eclipse.org/dash/commits/web-app/schema.php HTML] formats.

== How Does it Work ==

* [[Dash Project/Commits Explorer/SVN|Extracting Data from SVN]]

== Known Problems ==

Here we are collecting information about incorrect or mis-classified commits reported by the explorer.

* Some user names were changed when OTI joined IBM. Commits by the old login should be classified under the new. These old logins are categorized as "unknown".

* People who have changed companies are being reported as having worked for their current company for all of history rather than as having worked for company A until 2005 and then company B.

* People categorized under "individual" may be associated with a company, just not an Eclipse member company that has signed a Member Committer Agreement. Or, the data may just need cleaning up. For example, [http://dash.eclipse.org/dash/commits/web-app/summary.cgi?company=y&year=x&project=tools.pdt PDT] lists [http://dash.eclipse.org/dash/commits/web-app/summary.cgi?login=y&year=x&project=tools.pdt&company=individual mspector] as an "individual", but that person has logged in to dev.eclipse.org from mail.zend.com:
{{codeblock|
 $ finger mspector <nowiki>|</nowiki> grep login
 Last login Fri Oct 19 11:00 (EDT) on pts/1 from mail.zend.com
}}

* http://dash.eclipse.org/dash/commits/web-api/commit-details.php has a LIMIT 1000 restriction on it for performance reasons. See {{bug|210492}}.

* Some queries return data in 1, 3, 6, 9 month intervals; others return year-to-date data. In order to be able to accurately compare these queries, a common interval must be used.

* Commits to the www.eclipse.org website content (/cvsroot/org.eclipse) are [http://dash.eclipse.org/dash/commits/web-api/commit-details.php?project=modeling.emf&year=2007&login=nickb&project=technology.phoenix mis-categorized] as [http://dash.eclipse.org/dash/commits/web-app/summary.cgi?top=x&year=y&project=technology.phoenix&login=nickb Phoenix project commits]. These should be split into "web commits" and "code commits" so that website content != phoenix project. See {{bug|210038}}.

* Checking in a new file to CVS results in a commit for which the Lines of Code (LOC) count is zero. See {{bug|211343}}.
