Java implementation of the bsdiff algorithm

jbsdiff

A Java implementation of bsdiff (http://www.daemonology.net/bsdiff/)

Usage

jbsdiff can be used from its command line interface:

java -jar jbsdiff.jar command oldfile newfile patchfile

Where command is either 'diff' or 'patch.' You can also specify the compression algorithm used during a diff operation by setting a system property:

java -Djbsdiff.compressor=gz -jar jbsdiff.jar diff a.bin b.bin patch.gz

Supported compression algorithms (from the Apache Commons Compress library) are bzip2 (the default), gz, pack200, and xz.

...but jbsdiff is mostly intended to be used as a library. See the ui package for usage examples.

Compiling

To build a local fat jar, run:

mvn clean package

New package release?

The package available in Maven Repository is quite an old one. Any chance for a new package with up-to-date dependencies?

is it compatible with bsdiff 4.3 ?

Apply pull request #18?

It's been there for almost 2 years, it's tiny, and it's clearly a fix.

java.lang.StackOverflowError

Hi,

While using this library, I am getting java.lang.StackOverflowError for one of the file on line
SuffixSort.java#L178,190
It is working fine for other files. I used mac's bsdiff utility on the same file and was able to generate patch successfully. Can you suggest something?

1.0 release on Maven Central?

Would it be possible to make a 1.0 release build (i.e. not a SNAPSHOT), and push it to Maven Central (http://search.maven.org/) ?

Maven central version mismatch?

The version in Maven central and the version in this repo are 1.0, however they seem to be different! For example: the version of Patch in this repo has support for passing in Files as arguments -- but the version in Maven central doesn't.

Would it be possible to bump the version and get the new one into Maven central?

Thanks!

is it binary compatible with bsdiff ?

thanks
