Subject: [PATCH v3 0/2] diff --no-index: support symlinks and pipes
Date: Sat, 18 Mar 2017 22:00:36 +0100
Message-ID: <20170318210038.22638-1-dennis@kaarsemaker.net> (raw)

git diff <(command1) <(command2) is less useful than it could be, all it outputs is:

diff --git a/dev/fd/63 b/dev/fd/62
index 9e6542b297..9f7b2c291b 120000
--- a/dev/fd/63
+++ b/dev/fd/62
@@ -1 +1 @@
-pipe:[464811685]
\ No newline at end of file
+pipe:[464811687]
\ No newline at end of file

Normal diff provides arguably better output: the diff of the output of the
commands. This series makes it possible for git diff --no-index to follow
symlinks and read from pipes, mimicking the behaviour of normal diff.

v1: http://public-inbox.org/git/20161111201958.2175-1-dennis@kaarsemaker.net/
v2: http://public-inbox.org/git/20170113102021.6054-1-dennis@kaarsemaker.net/

Changes since v2, prompted by feedback from Junio:

- A --derefence option was added and the default is no longer to dereference
  symlinks.
- Instead of looking at what canon_mode returns, use the original mode of 
  files to override behaviour for pipes.
- Turn the !S_ISREG(...) check into a should_mmap_file_contents helper.

Dennis Kaarsemaker (2):
  diff --no-index: optionally follow symlinks
  diff --no-index: support reading from pipes
