RPMCACHE(8) RPM Package Manager RPMCACHE(8)NAMErpmcache - Cache RPM Package Headers
SYNOPSISrpmcache [ PACKAGE_NAME ... ]
DESCRIPTIONrpmcache 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 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) 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/rpm/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)
