Thanks for everyone's careful reviews. In this patch, I introduce a new --merge-base=<commit> option to allow callers to specify a merge-base for the merge and extend the input accepted by --stdin to also allow a specified merge-base with each merge requested. Regards, Kyle Changes since v1: * Changed merge_incore_recursive() to merge_incore_nonrecursive() when merge-base is specified. * Fixed c style problem. * Moved commit lookup/die logic out to the parsing logic in cmd_merge_tree(). * use test_commit for test Changes since v2: * commit message * Rebased on top of en/merge-tree-sequence. * Set opt.ancestor to o->merge_base. Because opt.ancestor is a *char. To make it easier to pass parameters, I moved lookup_commit_reference_by_name() to real_ merge() again. * Added test comment. Changes since v3: * support --merge-base in conjunction with --stdin Changes since v4: * commit message * added input format document * changed the input format for specifying the merge-base when --stdin is passed * changed the output when --stdin and --merge-base are used at the same time * add comment for test Changes since v5: * improved test: remove the test repo after the test; avoid sub-shell.
