Error Handling Which Preserves Possible Problem File? #180
Description
Enhancement Request
During failed Build (not running under Jenkins, but in a console as root), a clean-up is performed which removes a temporary file of interest. For example, from Issue #179:
Running eselect locale set en_US.utf8
+ trap finish EXIT
+ cat
+ chmod +x /home/jlpoole/local/Build.Dist/build/GenPi64OpenRC/chroot/em-5481
+ /home/jlpoole/local/Build.Dist/scripts/chroot.py /em-5481
Traceback (most recent call last):
File "/usr/lib/python3.10/site-packages/pychroot/scripts/pychroot.py", line 130, in main
File "/usr/lib/python3.10/subprocess.py", line 503, in run
with Popen(*popenargs, **kwargs) as process:

self._execute_child(args, executable, preexec_fn, close_fds,

raise child_exception_type(errno_num, err_msg, err_filename)

+ finish
+ ret=1
+ rm -f /home/jlpoole/local/Build.Dist/build/GenPi64OpenRC/chroot/em-5481
+ exit 1

run complete.
The file of interest is em-5481, but a higher level handler removes the file.
jlpoole@jenk ~ $ ls -la /home/jlpoole/local/Build.Dist/build/GenPi64OpenRC/chroot/em-5481
ls: cannot access '/home/jlpoole/local/Build.Dist/build/GenPi64OpenRC/chroot/em-5481': No such file or directory
jlpoole@jenk ~ $
the "+ ret=1" suggests that the handler which then executes the "rm -f..." would know the script is in error mode and likewise might do something that makes the file, em-5481, available. I'm thinking maybe cp the file to /tmp and print out a status report of doing so. I'll take a look and the code and see if what I'm thinking of is possible. I thought filing an enhancement request might highlight this type of approach. If it can be done, I'll do it and see if I can preserve the temporary file for forensic analysis on a future failure.
