Just F Patch

Patching

Description:

Just F Patch is a patching format designed to fix an issue with UPS:

UPS validates results by comparing hashes within the patch to that of the entire resulting file.

JFP only does hashing on values which were actually modified and so multiple JFPs can be applied to a single file with data integrity intact.

The JFP format uses variable length integers and MD5 hashes and is therefore especially future proof, though not especially incredible.

Due to the JFP format’s specification the likelihood of forcing patches being a good idea is much more slim, so no ability to bypass checksum failures has been added. Source is available, however.

The latest version of the implementing application, along with test cases and specification documentation, may be obtained from here.

Command line support has been added.
