The QA wrapper tests the nightly builds of NSS. The actual
tests are being run are called from the QA script all.sh. I will add documentation
for the actual QA soon. The main purpose of the wrapper is: find out which
build (NSS version, date, Build Platform) to test on which machine (OS,
OS version) and construct a summary report, which is then mailed to the
nss developers (aka mailing list nss-qa-report@netscape.com). Please see
also the feature section.
nssqa - the script that calls the actual
qa script all.sh
qa_stat - sends out status reports
qaclean - if everything else fails
Sample global result, individual result and log files
The QA wrapper consistst mainly of scripts, most located in security/nss/tests and subdirectories, but run from /u/sonmi/bin
nssqa and qa_stat, the main scripts both include a common header (header)
and a common environment (set_environment).
Also used is mksymlinks and path_uniq
and qaclean.
The scripts that are used on a daily basis are located in /u/sonmi/bin and checked into security/nss/tests
Parameters and Options are the same for most scripts.
Parameters
nssversion (supported: 30b, 31, tip, default tip)
builddate (default - today, format mmdd)
Options
-y answer all questions with y - use at your own
risk... ignores warnings
-s silent (only usefull with -y)
-h, -? -help you guessed right - displays the usage
-d debug
-f <filename> - write the (error)output to filename
-fcron writes resultfile in the same location as
would the -cron
-m <mailinglist> - send filename to mailinglist
(csl) only useful
with -f on nssqa
-l <mozroot> run on a local build - does not
work at this time
-cron equivalient to -y -s -d -f $RESULTDIR/$HOST.<scriptname>
Please be aware that some iPlanet specific environments and features are being used.
-d Debug option might be removed from cron in a few weeks - or maybe
not
-l QA on local build is not fully implemented yet - will not be implemented,
all.sh can be called directly instead
Please do not use on Windows 95 and 98, ME platforms yet.
use -d if script behaves strange or exits unexpectedly
How to use the QA-wrapper
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.
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.
In any case, if you are using it, please let me know the results.

nssqa parameters and options
Pseudocode Description of nssqa
not quite up to date
header:init (global)
set flags and variables
to default values
signal trap (for interupts
and kills)
set HOST and DOMSUF variables
if running from cron
parse parameters and options
determine os and set up
the environment (espec. PATH)
set the directories to run
in (influenced by parameters and -l option)
set the directories for backward
compatibility testing
set and initialize the tmp
/ debugging / output files
nssqa:init (local)
locking: if nssqa is already
running on this systems (yes-exit,
no-lockfile)
set HOST and DOMSUF variables
if running interavtively
set flag to kill remaining
selfserv processes during cleanup
if QA platform different
from build platform create neccessary
symbolic links
wait for the build to finish
(max of 5h)
main:
repeated per test (optimized,
debug, 32, 64 bit)
set flags for this run of all.sh (optimized, debug, 32, 64 bit)
set the DIST directory (where the binaries reside)
kill running selfservers (sorry - just don't use the svbld
account if you need to do your own testing... I will fix
selfserv as soon as I can - but it hangs too often and
disturbs all following QA)
run all.sh
header:exit (global)
remove temporary files
kill remaining selfservers
send email to the list
errorhandling
Option / Parameter errors:
Exit with usage information
Severe errors: Exit wit errormessage
example: directory in which all.sh resides does not exist
can't create files or directories
build not done after 5 hours
is already running
Other errors: User is prompted
with the "errormessage - continue (y/n)?"
example: local DIST dir does not exist (continues with next all.sh)
outputdirectory does not exist (user can specify other)
Signals 2, 3, 15 are treated
as severe errors
Use qaclean as user "svbld" to get the propper permissions. It is supposed to clean up after a "hanging" QA and will also brutally kill, interupt and disturb any other nss related test or performance meassurement on the named machine. NT and 2000 might require an additional reboot, since the ps is not so good about telling us the actual programmname - so we can't kill them... Please note that this is a brute force script, it should not be used on a regular basis, file a bug whenever you have to use it, since hanging QA is nothing that should occur frequently
What it does:
qa_stat is the script that is being started from the svbld cron on kentuckyderby
every morning at 10:00 and runs some (very primitive) analysis on the qa
results.
I'd like to rewrite the whole thing in perl, and in a few weeks I might
just do this...
qa_stat parameters and options
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.
