From f5bbc3225c4b073a7ff3218164a0c820299bc9c6 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Kristian=20H=C3=B8gsberg?= Date: Thu, 8 Nov 2007 11:59:00 -0500 Subject: Port git commit to C. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This makes git commit a builtin and moves git-commit.sh to contrib/examples. This also removes the git-runstatus helper, which was mostly just a git-status.sh implementation detail.

Mark Drago had a subversion repository which was then converted to hg and now is moving in to git. The first commit in the svn repo was just the creation of the empty directory. This made its way in to the hg repository fine, but converting from hg to git would cause an error. The problem was that hg-to-git.py tries to commit the change, git-commit fails, and then hg-to-git.py tries to checkout the new revision and that fails (because it was not created). This may have only caused an error because it was the first commit in the repository. If an empty directory was added in the middle of the repo somewhere things might have worked out fine. This patch will use the new --allow-empty option to git-commit to record such an "empty" commit, to reproduce the history recorded in hg more faithfully.
