Red Hat Bugzilla – Bug 1284893
"coredumpctl dump" doesn't output uncompressed core files
Last modified: 2016-12-20 11:13:33 EST
Description of problem:
If I use "Compress=no" in /etc/systemd/coredump.conf, "coredumpctl dump -o core" creates an empty file (core). "coredumpctl dump" outputs "Refusing to dump core to tty" and "coredumpctl dump | cat" doesn't output anything different to the previous.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. In /etc/systemd/coredump.conf, specify "Compress=no".
2. Set coredump limit to unlimited.
3. Cause an application to core dump.
4. Extract core file with "coredumpctl dump -o core"
Zero size core file.
Actual core file.
Whilst original core file is available in /var/lib/systemd/coredump (I can see it and use it), it would clearly be good to not have to be aware of whether or not systemd-coredump is using compression to store core file.
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 23 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
