[Bug 1788681] Re: changed exit code for 'dc' in Ubuntu Bionic
Fix has only been released for Cosmic. Given the package is basically non-functional on Bionic, is there a plan to backport the fix? There doesn't seem much point in keeping it in the repository otherwise. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1788681 Title: changed exit code for 'dc' in Ubuntu Bionic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bc/+bug/1788681/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This bug was fixed in the package dphys-swapfile - 20100506-5 --- dphys-swapfile (20100506-5) unstable; urgency=high * Add patch to fix the setup subcommand exiting prematurely with more recent dc versions. (Closes: #906767, LP: #1788681) Also update check-diskspace-first.patch which uses the same syntax. Thanks to eHenry Berg for the initial bug report, Davide Prina for additional debugging help, and Wladimir Mutel for finding the actual culprit. -- Axel Beckert Thu, 23 Aug 2018 23:29:41 +0200 ** Changed in: dphys-swapfile (Ubuntu) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1788681 Title: changed exit code for 'dc' in Ubuntu Bionic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bc/+bug/1788681/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This might be the cause for https://bugs.debian.org/906767 which I'm currently trying to fix. > which for some ironic reason uses 'dc' instead of 'echo > $((...))' for its calculations. That's upstream's decision. And since I know that upstream also runs rather old Unices, I assume it's because $(( ... )) might not be available in all shells. According to https://en.wikipedia.org/wiki/Comparison_of_command_shells#cite_ref-57 it should though be available in all relevant shells since 1992. The relevant change in dc seems to be from 1.3 to 1.4: Detects and reports on any output errors; exits non-success. The fix seems simple: Drop the "q": ~ → echo 1 1 + p q | dc ; echo $? 2 1 ~ → echo 1 1 + p | dc ; echo $? 2 0 Will have to check if that's indeed the cause for https://bugs.debian.org/906767, but will do a new upload to Debian Unstable in either case. Someone else will need to take care of a regression fix for bionic though.

same is reproduced when you run 'dc', enter into it some expression ending with 'p q', and examining its exit code with 'echo $?' afterwards -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1788681 Title: changed exit code for 'dc' in Ubuntu Bionic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bc/+bug/1788681/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
