Dir Signature
Status: Beta
Documentation | Github | Crate
This crate allows to create a signature (index) of a directory with files, which is:
- Reproducible (does not depend on order of file scan)
- Easy to check even using a bash script (sans edge cases)
- Usable for file synchonization
- Can be produced and checked without loading full index into memory

Directory Signature Library
v1
Currently we have only implemented v1
version of signature file,
it has the following limitations:
- Only stores executable bit for files, no permissions and ownership support (this also means files can be replicated without privileges)
- File modification times are not checked and not replicated
- It's ascii text, so potentially 2x larger than what binary file could be
While these limitations are not enough for generic backup purposes they are fine for deploying configs and read-only images to production servers in 99% use cases. Latter was a primary use case for the library. We will probably make a more featureful format as v2 and later as deemed necessary.
Design of the format features the following things:
- Reproducible (does not depend on order of file scan)
- Easy to check even using a bash script (sans edge cases)
- Usable for file synchronization
- Can be produced and checked without loading full index into memory
