From 20e8b465a53e651cc3f50bd60f39d577ecdb7722 Mon Sep 17 00:00:00 2001 From: Tay Ray Chuan Date: Fri, 8 Jan 2010 10:12:42 +0800 Subject: refactor ref status logic for pushing Move the logic that detects up-to-date and non-fast-forward refs to a new function in remote.[ch], set_ref_status_for_push(). Make transport_push() invoke set_ref_status_for_push() before invoking the push_refs() implementation. (As a side-effect, the push_refs() implementation in transport-helper.c now knows of non-fast-forward pushes.) Removed logic for detecting up-to-date refs from the push_refs() implementation in transport-helper.c, as transport_push() has already done so for it. Make cmd_send_pack() invoke set_ref_status_for_push() before invoking send_pack(), as transport_push() can't do it for send_pack() here. Mark the test on the return status of non-fast-forward push to fail. Git now exits with success, as transport.c::transport_push() does not check for refs with status REF_STATUS_REJECT_NONFASTFORWARD nor does it indicate rejected pushes with its return value. Mark the test for ref status to succeed. As mentioned earlier, refs might be marked as non-fast-forwards, triggering the push status printing mechanism in transport.c.
