Hi Łukasz Zemczak (sil2100),
With regard to the basic sanity-spin of the new ksh for each of the
other stable series to make sure those are not completely broken.
I have tested ksh against a number of regression tests offered in the
ksh source package itself.
--
To run all these tests with the shell you just built, go to the tests directory
and run the command:
SHELL=$dir/ksh $dir/ksh shtests
where dir is the directory of the ksh you want to test.
--
The output the regression tests are generating is very long, but to
summarize it test the binary in depth. Testing alias, append, arrays,
attributes, bracket, enum, exit, expand, functions, grep, io, leaks,
locale, math, namespace, path, options, quoting sigchld, signal,
variables, tilde, and many more.
Output example :
test sigchld passed at 2017-07-18+15:31:19 [ 14 tests 0 errors ]
test sigchld(C.UTF-8) begins at 2017-07-18+15:31:19
test sigchld(C.UTF-8) passed at 2017-07-18+15:31:35 [ 14 tests 0 errors ]
test sigchld(shcomp) begins at 2017-07-18+15:31:35
test sigchld(shcomp) passed at 2017-07-18+15:31:50 [ 14 tests 0 errors ]
I'm showing this above regression test output as an example and because
the bug was about a segfault after receiving a sigchld.
I won't hide that the test is sometime generating errors here and there, even
if the huge majority of the regression tests passed without errors. Amongst the
reported errors I can't find anything obvious that could be related to the
patch I have submitted.
I have strong believe these errors existed pre-SRU, and are probably
there for a while, since there is no new development nowadays for ksh
project.
Example of errors :
test bracket(C.UTF-8) begins at 2017-07-18+15:27:58
bracket.sh[86]: -r: /tmp/tmp.HapRrWwjIk/original should not be readable
bracket.sh[92]: -w: /tmp/tmp.HapRrWwjIk/original should not be writable
bracket.sh[95]: -x: /tmp/tmp.HapRrWwjIk/original should not be
executable
bracket.sh[98]: -rw: /tmp/tmp.HapRrWwjIk/original should not be
readable/writable
test bracket(C.UTF-8) failed at 2017-07-18+15:28:03 with exit code 1 [ 118
tests 1 error ]
Hope the above verification is enough for you to have confidence in the
-proposed package for X/Y/Z.
- Eric
