Affected Products:

  * SUSE Linux Micro 6.1

  
  
An update that has six fixes can now be installed.

## Description:

This update for libsolv, libzypp, zypper fixes the following issues:

libsolv was updated to 0.7.34:

  * add support for product-obsoletes() provides in the product autopackage
    generation code

libzypp was updated to 17.37.10:

  * BuildRequires: %{libsolv_devel_package} >= 0.7.34 (bsc#1243486) Newer rpm
    versions no longer allow a ':' in rpm package names or obsoletes. So
    injecting an "Obsoletes: product:oldproductname < oldproductversion" into
    the -release package to indicate a product rename is no longer possible.
    Since libsolv-0.7.34 you can and should use: "Provides: product-
    obsoletes(oldproductname) < oldproductversion" in the -release package.
    libsolv will then inject the appropriate Obsoletes into the Product.
  * Ignore DeltaRpm download errors (bsc#1245672) DeltaRpms are in fact optional
    resources. In case of a failure the full rpm is downloaded.
  * Improve fix for incorrect filesize handling (bsc#1245220)
  * Do not trigger download data exceeded errors on HTTP non data responses
    (bsc#1245220) In some cases a HTTP 401 or 407 did trigger a "filesize
    exceeded" error, because the response payload size was compared against the
    expected filesize. This patch adds some checks if the response code is in
    the success range and only then takes expected filesize into account.
    Otherwise the response content-length is used or a fallback of 2Mb if no
    content-length is known.
  * Fix SEGV in MediaDISK handler (bsc#1245452)
  * Explicitly selecting DownloadAsNeeded also selects the classic_rpmtrans
    backend. DownloadAsNeeded can not be combined with the rpm singletrans
    installer backend because a rpm transaction requires all package headers to
    be available the the beginning of the transaction. So explicitly selecting
    this mode also turns on the classic_rpmtrans backend.
  * Fix evaluation of libproxy results (bsc#1244710)

zypper was updated to 1.14.92:

  * sh: Reset solver options after command (bsc#1245496)
  * Explicitly selecting DownloadAsNeeded also selects the classic_rpmtrans
    backend.
