From 46ab7d46ca8ae98411450f077b3023e0b7e03ea9 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 17 Jun 2013 09:52:25 -0700 Subject: [PATCH 1/5] t7512: test "detached from" as well b397ea4863a1 (status: show more info than "currently not on any branch", 2013-03-13) wanted to make sure that after a checkout to detach HEAD, the user can see where the HEAD was originally detached from. The last test added by that commit to t7512 shows one example, immediately after HEAD is detached. Enhance that test to show "detached HEAD from" form that should be shown when the user further resetted to another commit.

This is because the reflog records "checkout" made by "rebase" as its implementation detail the same way as end-user initiated "checkout", and makes it count as the branch that was previously checked out.

Before this patch, with a detached HEAD, we saw: $ git status # Not currently on any branch. But after the patch, we see: $ git checkout v1.8.2 $ git status # HEAD detached at v1.8.2. It works by digging the reflog for the most recent message of the form "checkout: moving from xxxx to yyyy". It then asserts that HEAD and "yyyy" are the same, and displays this message. When they aren't equal, it displays: $ git status # HEAD detached from fe11db. so that the user can see where the HEAD was first detached. In case of a rebase [-i] operation in progress, this message depends on the implementation of rebase writing "checkout: " messages to the reflog, but that is an implementation detail of "rebase". To remove this dependency so that rebase can be updated to write better reflog messages, replace this "HEAD detached from" message with: # rebase in progress; onto $ONTO Changes to the commit object name in the expected output for some of the tests shows that what the test expected "status" to show during "rebase -i" was not consistent with the output during a vanilla "rebase", which showed on top of what commit the series is being replayed. Now we consistently expect something meaningful to the end user.
