NAME

----
|
|
git-patch-id - Compute unique ID for a patch
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git patch-id' < <patch>
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
A "patch ID" is nothing but a SHA1 of the diff associated with a patch, with
|
|
whitespace and line numbers ignored. As such, it's "reasonably stable", but at
|
|
the same time also reasonably unique, i.e., two patches that have the same "patch
|
|
ID" are almost guaranteed to be the same thing.
|
|
|
|
IOW, you can use this thing to look for likely duplicate commits.
|
|
|
|
When dealing with 'git-diff-tree' output, it takes advantage of
|
|
the fact that the patch is prefixed with the object name of the
|
|
commit, and outputs two 40-byte hexadecimal strings. The first
|
|
string is the patch ID, and the second string is the commit ID.
|
|
This can be used to make a mapping from patch ID to commit ID.
|
|
|
|
OPTIONS
|
|
-------
|
|
<patch>::
|
|
The diff to create the ID of.
