The rust oe-selftest output error log doesn't show any information on console when it fails.
The following changes emit stderr logs in terminal along with re-directing stdout and stderr to "summary.txt" file.

Changes made::
- cmd = cmd + " cd %s; python3 src/bootstrap/bootstrap.py test %s --target %s > summary.txt 2>&1;" % (builddir, testargs, targetsys)
+ cmd = cmd + " cd %s; python3 src/bootstrap/bootstrap.py test %s --target %s  > summary.txt 2> >(tee summary.txt >&2);" % (builddir, testargs, targetsys)


summary.txt:                  Redirects the standard output (stdout) of the command to a file 'summary.txt'

2> >(tee summary.txt >&2):      Redirects stderr & stdout to summary.txt & writes stderr on terminal

The overall effect is that both stdout and stderr are captured in the summary.txt file, while stderr still being displayed in the terminal.

Hi Yash, 

We talked about this change and decided that it's just too odd a shell pipeline to merge!

Also, it depends on the bash shell as you can tell by pasting:

   #!/bin/sh
   python3 src/bootstrap/bootstrap.py test %s --target %s  > summary.txt 2> >(tee summary.txt >&2);

into https://www.shellcheck.net/ . You'll see the following log and error:

$ shellcheck myscript
 
Line 2:
python3 src/bootstrap/bootstrap.py test %s --target %s  > summary.txt 2> >(tee summary.txt >&2);
                                                          ^-- SC2094 (info): Make sure not to read and write the same file in the same pipeline.

>>                                                                             ^-- SC2094 (info): Make sure not to read and write the same file in the same pipeline.


The YP goal / requirement is to avoid bash dependencies since user may be using dash or some other shell for /bin/sh.


I think that the command is being run locally (not on target), and we are already in a python context so
it seems that we would have a simpler solution if we handle the IO redirection from python.

Perhaps Richard or Joshua can recommend some code that you can reference when making this change.

Did you have time to look at the log file handling in runCmd()

https://git.openembedded.org/openembedded-core/tree/meta/lib/oeqa/utils/commands.py#n168

Please do some analysis and reply here every day or so as  you learn things or have questions.


Thanks,
