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 Mathieu Bridon 2012-05-25 08:45:07 UTC 
Created attachment 586802 [details]
backport of reloadConfig() (from master)

Description of problem:
From a discussion today in #fedora-devel:
<Panu> just fyi: using the rpm api for parsing specs has some not-so-obvious [... <Panu> the spec parse can and will affect the global rpm macro "environment" - eg macros defined by the spec will remain there after parsing
<Panu> ...and that in turn can and does affect results if you parse more than one spec (or just the same spec more than once) per process lifetime
[... snip ...]
<Panu> rpm 4.10 exports reloadConfig() function to python that'll reset the configuration, but for older versions the answer is "you dont want to do it" I'm afraid
<Panu> mind you, reloadConfig() is something that would be fairly trivial to backport to rpm 4.8 and 4.9 (so rhel-6 and upwards)

I'm attaching a patch which applies on top of upstream's rpm-4.8.x branch, as well as on the latest RHEL 6 srpm.
Comment 4 Panu Matilainen 2012-07-02 11:04:27 UTC 
devel_ack, the patch is non-intrusive and useful (for one, its required for parsing several specs within a single process reliably, so kinda related to bug 664427)
Comment 5 RHEL Program Management 2012-07-10 08:10:27 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 6 RHEL Program Management 2012-07-11 01:52:08 UTC 
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
Comment 7 RHEL Program Management 2012-08-14 22:00:02 UTC 
This request was evaluated by Red Hat Product Management for
inclusion in a Red Hat Enterprise Linux release.  Product
Management has requested further review of this request by
Red Hat Engineering, for potential inclusion in a Red Hat
Enterprise Linux release for currently deployed products.
This request is not yet committed for inclusion in a release.
