[PATCH 0/3] Update scripts

[PATCH 0/3] Update scripts

[Alexander Smirnov]

Hi all,

the key purpose of this series is to make ci and test scripts more
generic and easy to use by generic user. Also this series adds optional
verbose mode for these scripts.

After applying this series, Jenkins server will be updated to support
verbose output.

Now to build all Isar configuration user may run:

 $ scripts/ci_build.sh [-v]

To test all these configurations:

 $ cd build
 $ vm_smoke_test [-v]

With best regards,
Alex

[PATCH 1/3] scripts/vm_smoke_test: Add verbosity parameter

[Alexander Smirnov]

Issues:
1. Currently this script displays boot log for all the images. This could
   bring some inconviniences for users, who want to perform quick test and
   get just messages FAILED/PASSED.
2. Also the boot log is displayed if test case failed. So in the worst case
   when all cases for current image failed, the boot log will be displayed
   3 times.

Solution:
1. If at least one test case failed for current image, the boot log will be
   displayed (only one time, despite on number of cases failed).
2. Boot log is disabled by default. It could be enabled for all the images
   by '-v' option passed to this script.

[PATCH 3/3] scripts/ci_build: Make CI script more generic

[Alexander Smirnov]

Make this script more generic, so it could be used by any CI and by user
as well. Also add parameter to specify build folder.

Usage:
  ci_build [-v] -b BUILD_DIR

And this command will build all the default Isar images.

Both are features not issues. If one really wants less output you could
introduce an argument to reduce verbosity (-nv). Or please add the "-v"
to your CI setup. A CI build takes quite some time/ressources so it is
a good idea to keep logs by default to later understand why things
failed.

Looks to me like there is a case where BB_ARGS is not initialized and
that the default "-v" got dropped. Again this output is valuable and
should probably be there by default.

Read this last, sorry. If jenkins will add the "-v" it is OK but i
would still prefer the other way around (-nv). Other people setting up
their CI might forget the vs only to find them later.
