RHN Satellite Server 5.2.1

This is the RHN Satellite Server 5.2.1 General Availability Release.

This release of RHN Satellite fixes the following issues:

* An issue when the database was running into a deadlock and produced a
traceback from UpdateErrataCacheCommand was addressed. [bz# 468737]
* API function getEventHistory returned error when called after updating
packages on client from the Satellite; the datatypes causing the error were
fixed. [bz# 474079]
* Traceback during satellite-sync when errata has no description was
addressed. [bz# 474081]
* Support for yum group operations for cloned channels was added. [bz# 475846]
* Failure of simultaneous push of packages with different architectures,
when associated to the same errata, was fixed. [bz# 476492]
* Performance of selecting the Channels tab was improved. [bz# 483408]
* The taskomatic process was causing load spikes when processing
auto-update for erratas. [bz# 487611]
* Performance of bulk unsubscribing systems via System Set Manager was
improved. [bz# 488545]
* Ordering of config channels under activation key was fixed. [bz#
495583]
* New option use_repo_locking can be used to prevent multiple processes
generating yum metadata for the same channel to run. [bz# 495814]
* Reprovisioning with a new base channel via activation key was fixed. [bz#
496145]
* Wrong computation of applicable errata and package counts was fixed. [bz#
501086, 502963]
* Running satellite-sync from export on NFS was leading to [Errno 22]
Invalid argument error. The fcntl locking code was changed to address this
problem. [bz# 502665]
* When selected systems for configuration file deployment include
Configuration enabled clients which do not have deploy enabled, Satellite
generated 500: Internal Server Error. This issue was fixed. [bz# 502954]
* Wrong errata to be applied and wrong packages to be removed were selected
when using multiple browser tabs; the selection is now per-system. [bz# 502961]
* Rescheduling failed action for more than one system is slow and may fail
with 500: Internal Server Error; the cause was addressed. [bz# 502969, 502972]
* Satellite Web GUI would not allow patch to be installed to target Solaris
system; the systems are now correctly found and offered. [bz# 503987]
* Taskomatic would show tracebacks and the same errata notification would
be resent; the issue was addressed by tuning the query to use less
temporary space. [bz# 518080]
* The efficiency of yum metadata generation was improved by only running it
for channels that had changed. [bz# 527199]
* Calculation of errata cache was inconsistent across the application; the
issue was fixed. [bz# 529053]

Before applying this update, make sure that all previously released errata
relevant to your system have been applied.
