[Cdash] Update shows 'Unknown' user when the

[Michele Caramello]

Hi,

I noticed certain Update.xml submissions to Cdash (using SVN) can
cause the dashboard to believe a repository operation was done by an
unregistered user (Unknown). Consequently, dashboard warnings are
generated as well as back-end errors, Cdash log messages (see the
first extract below).

<< BEGIN LOG CDash error message >>
Warning reported on 2011-07-08 14:49:16 for build #9552
(SendEmail): User: Unknown is not registered (or has no email) for the project 1
<< END LOG>>

I have browsed the CDash mailing list archives and found nothing
matching. There was indeed a report for the same error but it was due
to other causes
(http://public.kitware.com/pipermail/cdash/2010-July/000824.html).
I have been chasing this one problem down for a while now and I
finally got the time to cross check the SVN log with CDash to find out
those happen when there is a repository deletion (SVN remove).

Further investigation made me actually think this is actually not a
Cdash issue but actually a real problem in the Update.xml (generated
by CTest) file and that is not consistent across submissions from
different machines (in this case I compared recent version of CTest
for WinXP 32 bits and Ubuntu 10.x 32 bits).
The 2 machines in fact performs the exact same tasks just on different
environments and that includes also the update of the repository at
each run.

Here is more details:
The Update.xml portion I pasted below shows how CTest's generated
Update.xml contains "Unknown" for the removed files in the repository.
This happens on the Linux machine.

CDash just reads the info in Update.xml and show "Unknown" next to the
removed files:

The particularity is the same problem does not happen for the CTest
execution from Windows, where the Update.xml simply marks the
deletions as updates:

<< BEGIN LOG Update.xml from CTest run on Windows machine for the remove file >>
<Updated>
  <File>lsm303a.c</File>
  <Directory>mllite/accel</Directory>
  <FullName>mllite/accel/lsm303a.c</FullName>
  <CheckinDate>2011-07-06T22:29:20.049970Z</CheckinDate>

  <Log>bug :1442 bug fixes</Log>
  <Revision>5726</Revision>
  <PriorRevision>5725</PriorRevision>
  </Updated>
<< END LOG>>

and therefore CDash shows assigns the deletion of the file to the proper author:

<< BEGIN LOG Update.xml message from CTest running on a Windows
machine for a normal svn update and a remove >>

On top of that, the Update.xml from Windows is a well formed xml
versus the Linux version seems it is not.

What are the chances this is caused by the different versions of SVN
running on the 2 machines (stock svn on Ubuntu, CollabNet command-line
svn client on Windows).

Thanks for bearing with me and reading through this.
