RPMCACHE(8)                      Red Hat Linux                     RPMCACHE(8)



NAME
       rpmcache - Cache RPM Package Headers

SYNOPSIS
       rpmcache [ PACKAGE_NAME ... ]


DESCRIPTION
       rpmcache  walks  a  file  tree,  possibly remotely using FTP, filtering
       paths using glob(7) expressions, reading rpm package headers. The  lat-
       est (i.e. comparing package epoch/version/release for identical package
       names and using the build time as a tie breaker)  package  headers,  if
       they are unique, are cached in an rpm database.  The rpm database cache
       can be used to provide suggested paths to packages that resolve unknown
       dependencies.

       There  are  no rpmcache specific options, only common rpm options.  See
       the rpmcache usage message for what is currently implemented.

       The file tree path to be searched is configured using rpm  macros.  The
       final  path is the concatentaion of 5 individual elements. Here are the
       macro names used to configure rpmcache, in the  same  order  that  they
       will be concatenated to build the file tree path that will be walked:


       %_bhpath
              The "path" level contains the leading part of the file tree path
              (or URL) for the file tree to be  walked.   No  glob(7)  expres-
              sions, here, please.

       %_bhcoll
              The "collection" level contains a string (or glob(7) expression)
              to match sub-directories of %_bhpath.

       %_bhN  The "name" level contains a string (or  glob(7)  expression)  to
              match  sub-directories  of %_bhcoll.  The PACKAGE_NAME arguments
              are used to construct a glob(7) expression that will  match  any
              of  specific  package names within the Red Hat build system, and
              are almost certainly not of use to anyone outside of Red Hat.

       %_bhVR The  "version-release"  level  contains  a  string  (or  glob(7)
              expression) to match sub-directories of %_bhN.

       %_bhA  The  "arch"  level  contains a string (or glob(7) expression) to
              match sub-directories of %_bhVR.

       The location of the cache database is  also  configured  using  an  rpm
       macro:

       %_cache_dbpath
              The  location  of  the  cache  database.  The  default  value is
              /var/spool/up2date/cache.

       The cache database is identical in format to an rpm database,  and  can
       be  used  with rpm from the command line. For example, to use the cache
       database to provide suggestions for packages that provide  dependencies
       needed  by  a package install, the following macro should be configured
       in either /etc/rpm/macros or ~/.rpmmacros:

       %_solve_dbpath
              The location of the database that is used to  provide  suggested
              dependency resolutions.


   Example (minimal) configuration for a Red Hat beehive tree:
       %_cache_dbpath  /var/spool/up2date/cache
       %_solve_dbpath  %{_cache_dbpath}
       %_bhpath        file://localhost/mnt/redhat/beehive/comps/dist
       %_bhcoll        7.3
       %_bhN           @(basesystem|bash|filesystem|glibc-common|glibc|ldconfig|libtermcap|mktemp|setup|termcap)
       %_bhVR          *
       %_bhA           @(i[3456]86|noarch)

   Example (minimal) configuration for a Red Hat FTP tree:
       %_cache_dbpath  /var/spool/up2date/cache
       %_solve_dbpath  %{_cache_dbpath}
       %_bhpath        ftp://localhost/mnt/dist
       %_bhcoll        @(7.3|7.2|7.1|7.0|6.2|6.1|6.0|5.2|5.1|5.0)
       %_bhN           @(%{_arch})
       %_bhVR          *
       %_bhA           @(i[3456]86|noarch)
