Add options to refs/for/ magic branch syntax
Git doesn't want to modify the network protocol to support passing data from the git push client to the server. Work around this by embedding option data into a new style of reference specification: refs/for/master%r=alice,cc=bob,cc=charlie,topic=options is now parsed by the server as: - set topic to "options" - CC charlie and bob - add reviewer alice - for branch refs/heads/master If % is used the "extra information" after the branch name is parsed as options with args4j. Each option is delimited by ",". Selecting publish vs. draft should be done with options draft or publish, appearing anywhere in the refspec after the % marker: refs/for/master%draft refs/for/master%draft,r=alice refs/for/master%r=alice,draft refs/for/master%r=alice,publish Change-Id: I895bd1218c2099b5b45cac943039bbd12565370c
