2017-04-02diff: submodule inline diff to initialize env array.Libravatar Stefan Beller1-0/+29
David reported: > When I try to run `git diff --submodule=diff` in a submodule which has > it's own submodules that have changes I get the error: fatal: bad > object. This happens, because we do not properly initialize the environment in which the diff is run in the submodule. That means we inherit the environment from the main process, which sets environment variables. (Apparently we do set environment variables which we do not set when not in a submodules, i.e. the .git directory is linked) This commit, just like fd47ae6a5b (diff: teach diff to display submodule difference with an inline diff, 2016-08-31) introduces bad test code (i.e. hard coded hash values), which will be cleanup up in a later patch.

2016-08-31diff: teach diff to display submodule difference with an inline diffLibravatar Jacob Keller1-0/+749
Teach git-diff and friends a new format for displaying the difference of a submodule. The new format is an inline diff of the contents of the submodule between the commit range of the update. This allows the user to see the actual code change caused by a submodule update. Add tests for the new format and option.
