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 latest (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 concatenation 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) expressions, 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)
