continuity
A transport-agnostic, filesystem metadata manifest system
This project is a staging area for experiments in providing transport agnostic
metadata storage.
Please see https://github.com/opencontainers/specs/issues/11 for more details.
Manifest Format
A continuity manifest encodes filesystem metadata in Protocol Buffers.
Please refer to proto/manifest.proto.
Usage
Build:
$ make
Create a manifest (of this repo itself):
$ ./bin/continuity build . > /tmp/a.pb
Dump a manifest:
$ ./bin/continuity ls /tmp/a.pb
...
-rw-rw-r-- 270 B /.gitignore
-rw-rw-r-- 88 B /.mailmap
-rw-rw-r-- 187 B /.travis.yml
-rw-rw-r-- 359 B /AUTHORS
-rw-rw-r-- 11 kB /LICENSE
-rw-rw-r-- 1.5 kB /Makefile
...
-rw-rw-r-- 986 B /testutil_test.go
drwxrwxr-x 0 B /version
-rw-rw-r-- 478 B /version/version.go
Verify a manifest:
$ ./bin/continuity verify . /tmp/a.pb
Break the directory and restore using the manifest:
$ chmod 777 Makefile
$ ./bin/continuity verify . /tmp/a.pb
