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.

Fixed In Version:	scl-utils-20120927-7.el6	Doc Type:	Bug Fix
Doc Text:	* When starting an inspection of what collections are already enabled, a wrong variable was taken as a source of this information. In a specific case, when users ran a shell in an scl_enabled environment, and tried to enable an already-enabled collection, then the collection was enabled twice. This could have caused problems if the enable scriptlets were not prepared for something like this, and might have destroyed some parts of the original environment. This update accepts the correct variable as a source of information about the already-enabled collections, and the collections are no longer enabled multiple times.	Story Points:	---

Description Jan Zeleny 2013-04-23 13:46:40 UTC

+++ This bug was initially created as a clone of Bug #955668 +++

When running scl enable <collection> bash, a variable $X_SCLS should be filled with a list of collections that are enabled. When calling scl enable for the second time, content of $x_scls is read instead of $X_SCLS. In case of enabling the same collection again, it would lead to running collection's enable scriptlet twice.

In some specific cases, this can lead to malformed environment, as one of the basic assumptions of scl-utils is that once collection is enabled, it won't be enabled for the second time.
