[PATCH] control/limit output of git-rev-list
From: Kay Sievers <hidden>
Date: 2016-06-15 22:41:56
gitweb.cgi's default view is the log of the last day and git-rev-list
can stop crawling the whole repo if we have all our data to display in the
browser. Also the rss-feed query needs only the last 20 items. This
will speeds up these queries dramatically.
usage: rev-list [OPTION] commit-id
--max-count=nr
--max-age=epoch
--min-age=epoch

Pasky, kernel.org uses the cogito binaries. It would be nice, if you can
include this into the next release, so we can safe these boxes a whole lot
of useless work.
Thanks,
Kay
