From: Junio C Hamano Date: Wed, 15 Aug 2018 22:08:23 +0000 (-0700) Subject: Merge branch 'bw/clone-ref-prefixes' X-Git-Tag: v2.19.0-rc0~76 X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/2d7a20258f791485d0fa0094e930eee094a77076?hp=402c47d939160acc389bbff083fbce9f5482a275 Merge branch 'bw/clone-ref-prefixes' The wire-protocol v2 relies on the client to send "ref prefixes" to limit the bandwidth spent on the initial ref advertisement. "git clone" when learned to speak v2 forgot to do so, which has been corrected. * bw/clone-ref-prefixes: clone: send ref-prefixes when using protocol v2 --- diff --git a/.gitignore b/.gitignore index 388cc4beee..3284a1e9b1 100644 --- a/.gitignore +++ b/.gitignore @@ -119,6 +119,7 @@ /git-rebase--helper /git-rebase--interactive /git-rebase--merge +/git-rebase--preserve-merges /git-receive-pack /git-reflog /git-remote diff --git a/.mailmap b/.mailmap index df7cf6313c..f165222a78 100644 --- a/.mailmap +++ b/.mailmap @@ -35,11 +35,13 @@ Chris Wright Cord Seele Christian Couder Christian Stimming +Christopher Díaz Riveros Christopher Diaz Riveros Csaba Henk Dan Johnson Dana L.
