Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Description of problem:
When a child process is started, and finished before a call to wait, an error is signaled.
Version-Release number of selected component (if applicable):
zsh-4.3.10-7.el6.x86_64
How reproducible:
100%
Steps to Reproduce:
Run the following script with zsh (or with zsh in ksh emulation mode):
#!/bin/ksh
sh -c "echo done" &
pid1=$!
sleep 1
wait $pid1
echo "rc: $?"
sh -c "exit 3" &
pid2=$!
sleep 1
wait $pid2
echo "rc: $?"
Actual results:
$ zsh test.sh
done
test.sh:wait:5: pid 6156 is not a child of this shell
rc: 1
test.sh:wait:11: pid 6159 is not a child of this shell
rc: 1
Expected results:
$ zsh test.sh
done
rc: 0
rc: 3
Additional info:
This is equally so for running zsh in ksh emulation mode. Running the same script with either bash or mksh, produces the expected result.
