The CernVM-FS python package allows for the inspection of CernVM-FS
repositories using python. In particular to browse their file catalog
hierarchy, inspect CernVM-FS repository manifests (a.k.a. .cvmfspublished
files) and the history of named snapshots inside any CernVM-FS repository.
The support for this package is low: best effort, and with very
limited testing.
Example Usage:
import cvmfs
repo = cvmfs.open_repository('http://cvmfs.fnal.gov/cvmfs/grid.cern.ch')
print 'Last Revision:' , repo.manifest.revision , repo.manifest.last_modified
root_catalog = repo.retrieve_catalog(repo.manifest.root_catalog)
print 'Catalog Schema:' , root_catalog.schema
for nested_catalog_ref in root_catalog.list_nested():
print 'Nested Catalog at:' , nested_catalog_ref.root_path
print 'Listing repository'
for full_path, dirent in repo:
print full_path
Example programs "big_catalogs" and "catdirusage" are supplied in the
"utils" directory, which are also useful for figuring out where to
split up the catalogs in a cvmfs repository.
Rpms are available in the cvmfs-contrib yum repositories for EL6 & 7.
See https://cvmfs-contrib.github.io for instructions to enable one
of those repositories. Then to install simply do:
# yum install -y python-cvmfsutils
