35 0store provides access to the low-level implementation cache. Normally, the
36 cache is updated automatically using 0launch(1).
40 To add a directory to the store (makes a copy):
42 .B 0store add sha1=XXX directory
45 To add an archive to the store:
47 .B 0store add sha1=XXX archive.tgz
50 To add a subdirectory of an archive to the store:
52 .B 0store add sha1=XXX archive.tgz subdir
55 The actual digest is calculated and compared to the given one. If they don't
56 match, the operation is rejected.
60 Verifies every implementation in each of the given cache directories, or in all of the
61 default cache directories if no arguments are given. This will detect any packages which
62 have been tampered with since they were unpacked. If 0store itself could have been
63 modified by an attacker, mount the suspect file-system on a known-good machine and
64 run that machine's 0store on the mounted cache directory.
67 See the "verify" command below for details of the verification performed on each package.
71 To copy an implementation (a directory with a name in the form
72 "algorithm=value"), use the copy function. This is similar to performing
73 a normal recursive directory copy followed by a
75 to check that the name matches the contents. E.g.:
77 .B 0store copy ~someuser/.cache/0install.net/implementations/sha256=XXX
78 /var/cache/0install.net/implementations/
82 To find the path of a stored item:
84 .B 0store find sha1=XXX
89 See the list of implementation caches currently configured:
93 To add directories to this list, add them to your 'implementation-dirs'
98 To generate the manifest for a directory structure:
100 .B 0store manifest DIRECTORY [ALGORITHM]
103 The manifest lists every file and directory in the tree, along with the
104 digest of each file, thus uniquely identifying that particular set of files.
105 After the manifest, the last line gives the digest of the manifest itself.
108 This value is needed when creating interface files. However, the 0publish
109 command will automatically calculate the required digest for you and add it
110 to an interface file. See the packager's guide on the Zero Install web site for
113 Supported algorithms are 'sha1' (supported by all versions), 'sha1new'
114 (requires injector 0.20 or later) and 'sha256' (requires injector 0.20 or later
115 AND the Python hashlib module).
119 To hard-link duplicate files together to save space:
121 .B 0store optimise [CACHE]
124 This reads in all the manifest files in the cache directory (~/.cache/0install.net/implementations
125 by default) and looks for duplicates (files with the same permissions, modification time and digest).
126 When it finds a pair, it deletes one and replaces it (atomically) with a hard-link to the other.
129 Implementations using the old 'sha1' algorithm are not optimised.
133 To check that an item is stored correctly:
135 .B 0store verify /path/to/sha1=XXX
137 This calculates the manifest of the directory and checks that its digest matches
138 the directory's name. It also checks that it matches the digest of the .manifest
139 file inside the directory. If the .manifest doesn't correspond to the current
140 tree, it displays a list of the differences (in unified diff format).
