bsdiff-rs

bsdiff-rs is an implementation of the bsdiff algorithm for generating and applying binary patches.

In addition to the raw algorithm, there is support for two container formats.

• BsDiff43 -> https://github.com/mendsley/bsdiff
• JBsDiff40 -> https://github.com/malensek/jbsdiff

Using

Currently, this project is not in crates.rs. For now, use it by cloning the repo from github. To add it as a dependency, add the following into your cargo.toml:

[dependencies]
bsdiff-rs = { git = "https://github.com/robot-rover/bsdiff-rs" }

Optional Features

bsdiff-rs also supports using mendsley/bsdiff as a backend and wrapping the C code. To use this rather than the rust backend, use the c_backend feature. To build this, you must also clone the submodules for this repo.

Tests

To run basic unit tests, simply run cargo test. However, there are also more complicated integration tests. To use these, first run ./test_setup.sh. This will build the bsdiff C executables and the jbsdiff jar file which are used in the tests. Then, run cargo test --features=integration_test. To run these, you must also clone the submodules for this repo.
