Re: [Bug 1887863] Re: ksh2020 has massive memory issues
OK, Anuradha. Yes, 965072 looks like my issue. Regarding the hang, I had a typo in the command. That should have generated a syntax error but, instead, it hung. No big deal, though, and not worth filing a defect, something I try to avoid unless it's a major issue. I did 'apt install' the ksh93 package, a better solution than just copying the shell and updating /etc/alternatives. I created a github account. My ID is 'chrisbertin'. Thanks!

[Bug 1887863] Re: ksh2020 has massive memory issues
I believe the issue you're referring to is similar to this issue that was filed recently regarding the "Exec format error": https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=965072 Will bring it up with the folks working on ksh93 to see if there's a resolution that can be found. Let me know if there's a github id that I can tag you on for any updates related to it. Since you're on focal, you can use the 'ksh93' package, which is basically ksh93u+ that was spun off as a result of the transition to ksh2020 on the 'ksh' package. Recently, we have reverted ksh2020 back to ksh93 and removed the "ksh93" package in Debian. So please track the following package in Ubuntu for updates as this is back to ksh93 and should address your original issue on this bug report. https://launchpad.net/ubuntu/+source/ksh ** Bug watch added: Debian Bug tracker #965072 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=965072 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1887863 Title: ksh2020 has massive memory issues To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ksh/+bug/1887863/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 1887863] Re: ksh2020 has massive memory issues
Anarudha, I am on Focal Fossa and the ksh93 version is: $ ksh93 --version version sh (AT Research) 93u+ 2012-08-01 Ksh93 is pretty clean and it has only one major bug that I never filed a ticket for: the handling 'command | while read ...'. A simple example is: $ ls | while read f; do [ -f "$f" ] || continue; cp $f /tmp/test/.; done cp: cp: cannot execute [Exec format error] cp: cp: cannot execute [Exec format error] cp: cp: cannot execute [Exec format error] cp: cp: cannot execute [Exec format error] cp: cp: cannot execute [Exec format error] cp: cp: cannot execute [Exec format error] cp: cp: cannot execute [Exec format error] cp: cp: cannot execute [Exec format error] cp: cp: cannot execute [Exec format error] cp: cp: cannot execute [Exec format error] cp: cp: cannot execute [Exec format error] cp: cp: cannot execute [Exec format error] cp: cp: cannot execute [Exec format error] Whenever I am hit with this issue, I just run the command in a sub- shell: $ ksh -c 'ls | while read f; do [ -f "$f" ] || continue; cp $f /tmp/test/.; done' The workaround is simple enough that I never bothered to file a ticket. But, just trying it again, this bug has gotten worse with the FF version!: this kind of loop now hangs after it's completed, whether or not it is run in a sub-shell! The valgrind output of 'ksh93 -l' is attached. If you send me a copy of the Groovy Gorilla ksh93, I can give it a spin and, if it's not fixed, I can file a ticket. Or I can file a ticket for the FF version right now.

Chris, thanks for the report and Valgrind observations. We have reverted ksh2020 back to ksh93u+, in Debian and Ubuntu with the latest version 2020.0.0+really93u+20120801-8 as of this writing available for Groovy Gorilla when you install the "ksh" package.
