From c976d415e5352886f0650f8e2edba81866c38587 Mon Sep 17 00:00:00 2001 From: Lars Hjemli Date: Tue, 28 Nov 2006 15:47:40 +0100 Subject: git-branch: add options and tests for branch renaming Extend git-branch with the following options: git-branch -m|-M [] newbranch The -M variation is required to force renaming over an exsisting branchname. This also indroduces $GIT_DIR/RENAME_REF which is a "metabranch" used when renaming branches. It will always hold the original sha1 for the latest renamed branch. Additionally, if $GIT_DIR/logs/RENAME_REF exists, all branch rename events are logged there. Finally, some testcases are added to verify the new options.

Also, builtin-branch.c is modified to provide a proper logmessage + call setup_ident() before any logmessages are written.
