From 40d52ff77b093fa48f58a168f4b0c4e65b862e56 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Thu, 1 Apr 2010 20:05:23 -0400 Subject: make commit_tree a library function Until now, this has been part of the commit-tree builtin. However, it is already used by other builtins (like commit, merge, and notes), and it would be useful to access it from library code. The check_valid helper has to come along, too, but is given a more library-ish name of "assert_sha1_type". Otherwise, the code is unchanged. There are still a few rough edges for a library function, like printing the utf8 warning to stderr, but we can address those if and when they come up as inappropriate.

It in general is a better style to have an exception handling out of line from the main codepath and make error codepath jump forward.
