It may make sense to enable reflogs everywhere by default in some\nmajor version bump.\n\nAlso a distribution point repository is often served by gitweb and it\nwould be really nice if there were an option to allow its summary view\nto show commits annotated with reflog entries, e.g.\n\n ----------------------------------------------------------------\n 2 days ago JCH Merge branch 'maint'\n (pushed 6 hrs ago)\n ----------------------------------------------------------------\n 2 days ago DVL Makefile: add compat/bswap.h to LIB_H\n ----------------------------------------------------------------\n 3 days ago JCH Revert \"Don't create the $GIT_DIR/branches directory on init\"\n (pushed 60 hours ago)\n ----------------------------------------------------------------\n 4 days ago JCH fixup tr/stash-format merge\n ----------------------------------------------------------------\n ...\n"},{"id":"126794","messageId":"vpqeioeaz53.fsf@bauges.imag.fr","threadId":"21480","inReplyTo":"alpine.LFD.2.00.0911041243350.10340@xanadu.home","subject":"Re: Accessing the reflog remotely","fromName":"Matthieu Moy","fromEmail":"matthieu.moy@grenoble-inp.fr","sentAt":"2009-11-04T19:06:00Z","receivedAt":"2009-11-04T19:06:00Z","isPatch":false,"sender":{"key":"matthieu.moy@grenoble-inp.fr","avatar":"https://gravatar.com/avatar/72c8a2705971a25dfaff23cece15130d405685845d911aedd5667ace277f3fc5?d=mp&s=160"},"body":"Nicolas Pitre writes:\n\n> You could checkout the first revision which committer's date is older \n> than midnight.

In the particular case I have in mind, the\ndeliverable is an intermediate one, and we insist a lot on testing, so\nthe senario is not unlikely: commit dangerous code the day of the\ndeadline, and push it the day after.
