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.

Red Hat Product Errata RHBA-2011:1569 0 normal SHIPPED_LIVE matahari bug fix and enhancement update 2011-12-06 00:39:06 UTC

Description Adam Stokes 2011-09-19 18:40:30 UTC 
Description of problem:
Fresh install of RHEL 6.2 choosing the 'minimal' configuration causes matahari agents who attempt to capture a UUID to return NULL. Since c++ doesn't like this we are hit with an exception

terminate called after throwing an instance of 'std::logic_error'
  what():  basic_string::_S_construct NULL not valid
Aborted


Version-Release number of selected component (if applicable):
0.4.4-x

How reproducible:
100%

Steps to Reproduce:
1. install minimal os
2. install matahari 0.4.4
3. attempt to start an agent where both /etc/machine-id or /var/lib/dbus/machine-id are not present
  
Actual results:
terminate called after throwing an instance of 'std::logic_error'
  what():  basic_string::_S_construct NULL not valid
Aborted


Expected results:
agents to connect to broker

Additional info:
https://github.com/matahari/matahari/blob/master/src/lib/utilities_linux.c#L83

We need to be returning an empty string here.
Comment 1 Dave Johnson 2011-09-19 20:16:07 UTC 
This worked for me.  dbus gets installed and creates the machine-id file.

here is the ks file for the install

Comment 2 Russell Bryant 2011-09-19 22:38:50 UTC 
Fixed upstream:

https://github.com/matahari/matahari/commit/050aac205efebd2f9779a33605bd88ff3a99da49

This change will ensure the agents don't crash if neither systemd or dbus are installed.  The UUID field will be blank, but at least it doesn't crash ...
Comment 4 Dave Johnson 2011-11-03 22:43:07 UTC 
good 2 go with v0.4.4-9
