From 3bc2111fc2e9e8ff33b48bb2ccd17b77ca7dbced Mon Sep 17 00:00:00 2001 From: Slavica Djukic Date: Sun, 18 Nov 2018 14:44:07 +0100 Subject: [PATCH 1/1] stash: tolerate missing user identity The "git stash" command insists on having a usable user identity to the same degree as the "git commit-tree" and "git commit" commands do, because it uses the same codepath that creates commit objects as these commands. It is not strictly necesary to do so. Check if we will barf before creating commit objects and then supply fake identity to please the machinery that creates commits. Add test to document that stash executes correctly both with and without valid ident. This is not that much of usability improvement, as the users who run "git stash" would eventually want to record their changes that are temporarily stored in the stashes in a more permanent history by committing, and they must do "git config user.{name,email}" at that point anyway, so arguably this change is only delaying a step that is necessary to work in the repository.
