We presently use the ".txt" extension for our AsciiDoc files. While not wrong, most editors do not associate this extension with AsciiDoc, meaning that contributors don't get automatic editor functionality that could be useful, such as syntax highlighting and prose linting. It is much more common to use the ".adoc" extension for AsciiDoc files, since this helps editors automatically detect files and also allows various forges to provide rich (HTML-like) rendering. Let's do that here, renaming all of the files and updating the includes where relevant. Adjust the various build scripts and makefiles to use the new extension as well. Note that this should not result in any user-visible changes to the documentation. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

NAME

|
----
|
|
git-patch-id - Compute unique ID for a patch
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git patch-id' [--stable | --unstable | --verbatim]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Read a patch from the standard input and compute the patch ID for it.
|
|
|
|
A "patch ID" is nothing but a sum of SHA-1 of the file diffs associated with a
|
|
patch, with 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.
|
|
|
|
The main usecase for this command is 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
|
|
-------
|
|
|
|
--verbatim::
|
|
Calculate the patch-id of the input as it is given, do not strip
|
|
any whitespace.
|
|
|
|
This is the default if patchid.verbatim is true.
|
|
|
|
--stable::
|
|
Use a "stable" sum of hashes as the patch ID. With this option:
|
|
- Reordering file diffs that make up a patch does not affect the ID.
|
|
In particular, two patches produced by comparing the same two trees
|
|
with two different settings for "-O<orderfile>" result in the same
|
|
patch ID signature, thereby allowing the computed result to be used
|
|
as a key to index some meta-information about the change between
|
|
the two trees;
|
|
|
|
- Result is different from the value produced by git 1.9 and older
|
|
or produced when an "unstable" hash (see --unstable below) is
|
|
configured - even when used on a diff output taken without any use
|
|
of "-O<orderfile>", thereby making existing databases storing such
|
|
"unstable" or historical patch-ids unusable.
|
|
|
|
- All whitespace within the patch is ignored and does not affect the id.
|
|
|
|
This is the default if patchid.stable is set to true.
|
|
|
|
--unstable::
|
|
Use an "unstable" hash as the patch ID. With this option,
|
|
the result produced is compatible with the patch-id value produced
|
|
by git 1.9 and older and whitespace is ignored. Users with pre-existing
|
|
databases storing patch-ids produced by git 1.9 and older (who do not deal
|
|
with reordered patches) may want to use this option.
|
|
|
|
This is the default.
