We need the new QA wrapper, because we have to test on so many platforms,
|
||||
that running the tests and evaluating the results for the nightly builds
|
||||
took about an average workday.
|
||||
<p><b><font size=+1>New Features:</font></b>
|
||||
<ul>
|
||||
<li>
|
||||
runs from <b>cron</b> / rsh or <b>interactive</b> if desired</li>
|
||||
|
||||
<li>
|
||||
generates <b>summary</b> (no need to look through 60-90 directories)</li>
|
||||
|
||||
<li>
|
||||
sends <b>email</b> about results</li>
|
||||
|
||||
<li>
|
||||
automatically <b>recognizes common errors</b> and problems and conflicts
|
||||
and corrects them</li>
|
||||
|
||||
<br>(or attempts to correct them :-)
|
||||
<li>
|
||||
automatically determines <b>which build </b>to test (waits if build in
|
||||
progress, exits if no build)</li>
|
||||
|
||||
<li>
|
||||
runs on <b>all required platforms</b> (Windows 98 and before not functional
|
||||
yet)</li>
|
||||
|
||||
<li>
|
||||
also works on <b>local builds</b> (not fully functional yet)</li>
|
||||
|
||||
<li>
|
||||
Windows version runs on <b>free Cygnus</b> instead of MKS only (it has
|
||||
been decided by management that both need to be sopported, and the main
|
||||
focus needs to be on MKS, so cygnus is completely broken at the moment)</li>
|
||||
|
||||
<li>
|
||||
debug mode, normal mode and silent mode</li>
|
||||
|
||||
<li>
|
||||
<b>locking</b> mechanism so it won't run twice</li>
|
||||
|
||||
<li>
|
||||
<b>cleanup</b> after being killed and most errors (no remaining selfservers,
|
||||
tmpfiles, lock files)</li>
|
||||
</ul>
|
||||
The 1st script is started via cron between 5:00 and 8:00 am on different
|
||||
systems, and starts QA on the nightly build. At 10:00 the next script is
|
||||
started, and sends a QA summary to the nss developers.
|
||||
<p>Since all.sh never got to run on the MKS Tool kit on Win 95 and 98 and
|
||||
is almost unusable on NT and 2000 (I got a long list of problems, so does
|
||||
Larry, in case anyone is interested) we decided to move to the Cygnus tool
|
||||
kit, but unfortunately this project was abandoned when it was decided that
|
||||
MKS functionallity is not allowed to be broken.
|
||||
<p><b>Cygnus Advantages</b>:
|
||||
<ul>
|
||||
<li>
|
||||
<b>free</b></li>
|
||||
|
||||
<li>
|
||||
better handling of <b>processes</b> (background, processIDs, Signals)</li>
|
||||
|
||||
<li>
|
||||
Unix / Linux <b>compatible</b> sh / bash</li>
|
||||
</ul>
|
||||
<b>Disadvantages</b>
|
||||
<ul>
|
||||
<li>
|
||||
MKS functionality needs to be preserved (makes <b>8 Windows platforms</b>
|
||||
instead of 4 for the QA suites - makes 32 testruns on Windows alone)</li>
|
||||
|
||||
<li>
|
||||
In certain functionality's <b>slow</b></li>
|
||||
</ul>
|
||||
The new QA wrapper consistst mainly of 2 scripts, nssqa and qa_stat, both
|
||||
<br>include a common header (header) and a common environment (set_environment).
|
||||
<br>Also used is mksymlinks and path_uniq.
|
||||
<p>The scripts that are used on a daily basis are located in /u/sonmi/bin
|
||||
and checked into security/nss/tests
|
||||
<p>Parameters and Options are the same for both scripts.
|
||||
<p><b><u><font size=+1>Parameters</font></u></b>
|
||||
<br> nssversion (supported: 30b, 31, tip, default tip)
|
||||
<br> builddate (default - today, format mmdd)
|
||||
<p><b><u><font size=+1>Options</font></u></b>
|
||||
<br> -y answer all questions with y - use at your own
|
||||
risk... ignores warnings
|
||||
<br> -s silent (only usefull with -y)
|
||||
<br> -h, -? -help you guessed right - displays the usage
|
||||
<br> -d debug
|
||||
<br> -f <filename> - write the (error)output to filename
|
||||
<br> -fcron writes resultfile in the same location as
|
||||
would the -cron
|
||||
<br> -m <mailinglist> - send filename to mailinglist
|
||||
(csl) only useful
|
||||
<br> with -f on nssqa
|
||||
<br> -l <mozroot> run on a local build - does not
|
||||
work at this time
|
||||
<br> -cron equivalient to -y -s -d -f $RESULTDIR/$HOST.<scriptname>
|
||||
<p><b>nssqa and qa_stat are Beta , unfortunately I have a lot of other
|
||||
work and the progress on these scrripts is slow</b>
|
||||
<p>Please be aware that some iPlanet specific environments and features
|
||||
are being used.
|
||||
<p>-d Debug option might be removed from cron in a few weeks - or maybe
|
||||
not
|
||||
<br>-l QA on local build is not fully implemented yet
|
||||
<p>Please do not use on Windows 95 and 98, ME platforms yet.
|
||||
<p>use -d if script behaves strange or exits unexpectedly
|
||||
<p><b><font size=+1>How to use the QA-wrapper</font></b>
|
||||
<br>To test a build, first run nssqa on the required QA platforms (some
|
||||
buildplatforms require QA to be run on additional platforms - for example
|
||||
Solaris 2.6 has to be tested on 2.8 32 and 64bit) If QA has been run on
|
||||
multiple or all required platforms it makes sense to run qa_stat on the
|
||||
output of nssqa as well.
|
||||
<br>Before used on a new system (even if the same platform has been tested
|
||||
before) please use completely interactive, to see what the variables are
|
||||
being initialized to, and read the warnings. Same is true if being run
|
||||
from a different user account than svbld.
|
||||
<p>In any case, if you are using it, please let me know the results.
|
||||
