RHBA-2012:0909 - Bug Fix Advisory

Topic

Updated rpm packages that fix multiple bugs and add various enhancements are now
available for Red Hat Enterprise Linux 6.

Description

The RPM Package Manager (RPM) is a command-line driven package management system
capable of installing, uninstalling, verifying, querying, and updating software
packages.

This update fixes the following bugs:

• Previously, presence of ELF files prevented cross-architecture obsoletion of

packages on multi-arch systems, causing file conflicts when a supposedly
obsoleted package was not removed. With this update, obsoletes are now processed
for all matching package names regardless of their contents, allowing scenarios
like eliminating no longer needed 32-bit package variant on 64-bit multi-arch
systems to work as expected. (BZ#799317)

• Previously, a bug in execution of package scriptlets utilizing RPM's embedded

Lua interpreter could have caused RPM's working directory to change
inadvertently, resulting in a failure to install remaining local packages in the
transaction unless absolute paths were used to address the packages on the "rpm"
or "yum" command line. With this update, the Lua scriptlet execution now always
saves and restores the current working directory, ensuring correct operation
regardless of whether absolute or relative paths to packages are used.
(BZ#746190)

• Previously, the "-D" shortcut option for "--define" was incorrectly taken as a

shortcut for "--predefine", which led to incorrect macro evaluation when
attempting to override macros from system configuration. The "-D" shortcut
option now equals "--define" as intended and documented. (BZ#785236)

• Previously, RPM's "--last" query format output could have been ambiguous on

multi-arch systems such as AMD64/Intel 64 as package architecture was omitted.
Package's architecture is now included in "--last" output as well, making it
non-ambiguous and also consistent with the default query output format.
(BZ#768516)

• As the build dependencies recorded in source packages can vary depending on

the architecture where the source packages happened to be generated, using the
yum-builddep utility on a source package does not always report correct results.
RPM's Python bindings have now been enhanced to permit yum-builddep to operate
on spec files directly, ensuring that the correct build dependency information
for the local system is used. (BZ#664427)

• Previously, certain multi-line brace constructs could have caused the

automatic Perl dependency generator script to miss dependencies from pe. The
generator has now been updated to properly handle these situations. (BZ#752119)

Additionally, this update introduces the following feature enhancements:

• When building packages on file systems with a very high number of files, the

on-disk inode numbers could have been truncated in RPM's 32bit-integer-based
hardlink tracking, resulting in incorrect package generation and, consequently,
installation. RPM now uses per-package virtual numbering for hardlink tracking
to eliminate the possibility of truncation, ensuring correct operation
regardless of physical inode numbers at package build time, in a backwards
compatible way. (BZ#714678)

• Previously, RPM ignored any exit codes from %pretrans package scriptlets. This

was inconsistent with semantics of other scriptlets and prevented the
possibility of early abort of package installation before the transaction really
starts. RPM now treats %pretrans failure similarly to that of %pre: the package
with failing %pretrans scriptlet is not installed at all. (BZ#736960)

• Packages for Fedora 17 or later require a special rpmlib() dependency provided

by RPM to track the /usr merge that was completed in Fedora 17, otherwise it
will no be possible to use, for example, mock chroot to install and build
packages for that distribution. This special tracking dependency has been added
to RPM now to allow Red Hat Enterprise Linux 6 to be used as a host for building
packages for these newer Fedora versions. (BZ#761000)

All users of RPM are advised to upgrade to these updated packages, which fix
these bugs and add these enhancements.
