DESCRIPTION
|
|
|
|
-----------
|
2013-04-15 21:49:04 +04:00
|
|
|
A "patch ID" is nothing but a SHA-1 of the diff associated with a patch, with
|
2005-08-27 05:18:48 +04:00
|
|
|
whitespace and line numbers ignored. As such, it's "reasonably stable", but at
|
2006-06-04 00:27:26 +04:00
|
|
|
the same time also reasonably unique, i.e., two patches that have the same "patch
|
2005-08-27 05:18:48 +04:00
|
|
|
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
|
2005-10-28 13:39:56 +04:00
|
|
|
the fact that the patch is prefixed with the object name of the
|
2009-03-25 21:23:42 +03:00
|
|
|
commit, and outputs two 40-byte hexadecimal strings. The first
|
2005-10-28 13:39:56 +04:00
|
|
|
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.
