4.365. yum

An updated yum package that fixes several bugs and adds three enhancements is now available for Red Hat Enterprise Linux 6.
Yum is a command line utility that allows a user to check for and automatically download and install updated RPM packages. It automatically obtains and downloads dependencies, prompting the user for permission as necessary.

Bug Fixes

BZ#661962
When uninstalling a package, the "yum remove" command may have previously reported success even when the package could not be removed due to an error in the %pre scriptlet. With this update, this error has been fixed, and when yum fails to remove a package, it no longer claims that it succeeded.
BZ#697885
When running the "yum -v repolist" command, the previous version of the yum utility may have incorrectly displayed a duplicate "Repo-baseurl" line for a repository with no mirrors. This update applies a patch that corrects this error, and the output of the "yum -v repolist" command no longer contains duplicate lines.
BZ#704600
Previously, an attempt to install a package that was larger than 4 GB on a 32-bit architecture caused yum to terminate unexpectedly with a traceback. With this update, the underlying source code has been adapted to work around this problem, and packages larger than 4 GB can now be installed as expected.
BZ#707358
Prior to this update, running a yum command with the "--installroot" command line option caused it to report the following warning:
Ignored option -c (probably due to merging -yc != -y -c)
This update adapts the underlying source code not to display this warning when the "--installroot" option is in use, resolving this issue.
BZ#727574
Under certain circumstances, an attempt to use the RepoStorage API may have failed with an AttributeError. With this update, this error has been fixed, and the RepoStorage API can now be used as expected.
BZ#727586
Previously, the repodiff utility used a stale metadata cache in subsequent runs. When two repodiff commands were executed in succession, the second run reused cached data from the first. This bug has been fixed and repodiff now properly validates the metadata if a connection cannot be established or the cached data are about to be reused.
BZ#728253
Prior to this update, when the "yum -q history addon-info last saved_tx" command was used to store transaction data in a file, an attempt to supply this file to the "yum load-transaction" command in order to repeat the transaction failed with an error, because the output contained extra lines. This update corrects the underlying source code to make sure the "yum -q history addon-info last saved_tx" command produces valid output, and adapts "yum load-transaction" to accept older version of the output as well.
BZ#733391
In very rare cases, the yum utility may have incorrectly kept using old updateinfo, pkgtags, and groups metadata. When this happened, users may have been unaware of available updates for up to 6 hours. This update applies a patch that prevents yum from using outdated metadata, resolving this issue.

Enhancements

BZ#662243
The "yum history" command has been adapted to store and display yumdb and rpmdb information, such as from which repository was a particular package installed.
BZ#728526
The "yum update" command can now be used to update a package to a specific version.
BZ#694401
The yum utility no longer asks the user to report a bug when the dependency solver (depsolve) encounters an error.
All users of yum are advised to upgrade to this updated package, which fixes these bugs and adds these enhancements.

Bug Fix

BZ#795455
The anacron scheduler starts the yum-cron utility with the "nice" value of 10. This caused Yum's RPM transactions to run at very low priority level. Also, any updated service inherited this "nice" value, which influenced the system behavior. This update adds the "reset_nice" configuration option, which allows Yum to reset the "nice" value to 0 before running an RPM transaction. With this option set, Yum's RPM transactions run at normal priority level so that updated services are restarted with normal priority as expected.
All users of yum are advised to upgrade to this updated package, which fixes this bug.
