Usage ----- Run: 1. # mkdir /tmp/appfs-cache /opt/appfs 2. # appfsd /opt/appfs Paths ----- AppFS should normally be mounted on "/opt/appfs". /opt/appfs/hostname Fetches: http://hostname/appfs/index Contains CSV file: hash,extraData Fetches: http://hostname/appfs/sha1/<hash> Contains CSV file: package,version,os,cpuArch,sha1,isLatest /opt/appfs/hostname/package/os-cpuArch/version /opt/appfs/hostname/sha1/ Fetches: http://hostname/appfs/sha1/<sha1> Contains CSV file: type,time,extraData,name type == directory; extraData = (null) type == symlink; extraData = source type == file; extraData = size,perms,sha1 /opt/appfs/hostname/{sha1,package/os-cpuArch/version}/file Fetches: http://hostname/appfs/sha1/<sha1> Database -------- packages(hostname, sha1, package, version, os, cpuArch, isLatest, haveManifest) files(package_sha1, type, time, source, size, perms, file_sha1, file_name, file_directory) Resources --------- http://appfs.rkeene.org/ |
