32 0store provides access to the low-level implementation cache. Normally, the
33 cache is updated automatically using 0launch(1).
37 To add a directory to the store (makes a copy):
39 .B 0store add sha1=XXX directory
42 To add an archive to the store:
44 .B 0store add sha1=XXX archive.tgz
47 To add a subdirectory of an archive to the store:
49 .B 0store add sha1=XXX archive.tgz subdir
52 The actual digest is calculated and compared to the given one. If they don't
53 match, the operation is rejected.
57 To copy an implementation (a directory with a name in the form
58 "algorithm=value"), use the copy function. This is similar to performing
59 a normal recursive directory copy followed by a
61 to check that the name matches the contents. E.g.:
63 .B 0store copy ~someuser/.cache/0install.net/implementations/sha256=XXX
64 /var/cache/0install.net/implementations/
68 To find the path of a stored item:
70 .B 0store find sha1=XXX
75 See the list of implementation caches currently configured:
79 To add directories to this list, add them to your 'implementation-dirs'
84 To generate the manifest for a directory structure:
86 .B 0store manifest DIRECTORY [ALGORITHM]
89 The manifest lists every file and directory in the tree, along with the
90 digest of each file, thus uniquely identifying that particular set of files.
91 After the manifest, the last line gives the digest of the manifest itself.
94 This value is needed when creating interface files. However, the 0publish
95 command will automatically calculate the required digest for you and add it
96 to an interface file. See the packager's guide on the Zero Install web site for
99 Supported algorithms are 'sha1' (supported by all versions), 'sha1new'
100 (requires injector 0.20 or later) and 'sha256' (requires injector 0.20 or later
101 AND the Python hashlib module).
105 To hard-link duplicate files together to save space:
107 .B 0store optimise [CACHE]
110 This reads in all the manifest files in the cache directory (~/.cache/0install.net/implementations
111 by default) and looks for duplicates (files with the same permissions, modification time and digest).
112 When it finds a pair, it deletes one and replaces it (atomically) with a hard-link to the other.
115 Implementations using the old 'sha1' algorithm are not optimised.
119 To check that an item is stored correctly:
121 .B 0store verify /path/to/sha1=XXX
123 This calculates the manifest of the directory and checks that its digest matches
124 the directory's name. It also checks that it matches the digest of the .manifest
125 file inside the directory. If the .manifest doesn't correspond to the current
126 tree, it displays a list of the differences (in unified diff format).
