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the product is no longer active in Red Hat Bugzilla.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.
3. What is the nature and description of the request?
- after facing issues+crashes with gnome-shell it turned out that debugging options are quite limited at the moment
- customer tested DEBUG_SHELL="backtrace-segfaults" in .bash_profile to get a JS stack trace when gnome-shell crashed
- customer would like to have this implemented as a default for every gnome-shell which runs on a host
4. Why does the customer need this? (List the business requirements here)
- to better understand gnome-shell crashes in retrospect and support debugging gnome-shell issues
- if gnome-shell crashed and re-spawned there is no indicator in the logs by default
5. How would the customer like to achieve this? (List the functional requirements here)
- set environment variable DEBUG_SHELL="backtrace-segfaults" as default in gnome-shell so every gnome-shell process on this
host (independent from the user) dumps a JS stack trace in journal when gnome-shell crashes.
6. For each functional requirement listed, specify how Red Hat and the customer can test to confirm the requirement is successfully implemented.
- start a gnome-shell in userspace, open windows and gnome applications
- force the gnome-shell to crash by sending SEGV to the process
- check if the journal contains at least the header for the stack trace when crashed
- e.g. "Sep 02 12:30:43 <host> org.gnome.Shell.desktop[7197]: == Stack trace for context 0x26820c0 =="
7. Is there already an existing RFE upstream or in Red Hat Bugzilla?
- not known
8. Does the customer have any specific timeline dependencies and which release would they like to target (i.e. RHEL5, RHEL6)?
- no, asap
9. Is the sales team involved in this request and do they have any additional input?
- no
10. List any affected packages or components.
- gnome-shell
11. Would the customer be able to assist in testing this functionality if implemented?
yes

That's not true, there should be a line along the lines of
Oct 29 18:06:31 rhel7-unknow gnome-session[1532]: gnome-session-binary[1532]: WARNING: Application 'org.gnome.Shell.desktop' killed by signal 11

That said, treating an unset DEBUG_SHELL variable as "backtrace-segfaults" is certainly feasible.
