Subject: [PATCH v4 0/3] give more useful error messages while renaming branch (reboot)
Date: Sat, 10 Mar 2018 21:24:13 +0530	[thread overview]
Message-ID: <20180310155416.21802-1-kaartic.sivaraam@gmail.com> (raw)
In-Reply-To: <20171102065407.25404-1-kaartic.sivaraam@gmail.com>

It's been a long time since the v3 of the patch. So, it's worth restating
the reason behind this patch.

From v1 of this patch,

     In builtin/branch, the error messages weren't handled directly by the branch
     renaming function and was left to the other function. Though this avoids
     redundancy this gave unclear error messages in some cases. So, make
     builtin/branch give more useful error messages.

Changes since v3:

 - Handled more error related to old branch name.

 - Incorporated changes suggested in v3 which include using ';' as a sentence
   connector instead 'and'.

 - Error messages use the interpreted branch names (without the (refs/heads/ part).

The unrelated cleanup patches which were in the previous versions have
since been submitted as a separate series and have been merged into
the codebase.

The first two patches are related to the topic of this patch. The 3rd one
is a little typo fix that I noticed on the way.

This patch was based off 'master' and has been rebased to incorporate
the new changes to 'master'. So, it generally should apply cleanly on
'master'. Let me know if it doesn't.

The sample input/output cases for this patch are as follows,

	$ git branch
	* master
	  foo
	  bar

Before patch,

	# Case 1: Trying to rename non-existent branch
	$ git branch -m hypothet no_such_branch
	error: refname refs/heads/hypothet not found
	fatal: Branch rename failed

	# Case 2: Trying to rename non-existent branch to an existing one
	$ git branch -m hypothet master
	fatal: A branch named 'master' already exists.

	# Case 3: Trying to force update current branch
	$ git branch -M foo master
	fatal: Cannot force update the current branch.

	# Case 4: Trying to force rename an in-existent branch with an invalid name
	$ git branch -M hypothet ?123
	fatal: '?123' is not a valid branch name.

After patch,

	# Case 1: Trying to rename non-existent branch
	$ git branch -m hypothet no_such_branch
	fatal: branch 'hypothet' doesn't exist

	# Case 2: Trying to rename non-existent branch to an existing one
	$ git branch -m hypothet master
	fatal: branch 'hypothet' doesn't exist; branch 'master' already exists

	# Case 3: Trying to force update current branch
	$ git branch -M foo master
	fatal: cannot force update the current branch

	# Case 4: Trying to force rename an in-existent branch with an invalid name
	$ git branch -M hypothet ?123
	fatal: branch 'hypothet' doesn't exist; new branch name '?123' is invalid


Note: Thanks to the strbuf API that made it possible to easily
construct the composite error message strings!
