Raw Blame History

Back-port of upstream 9.3 patch to support multiple sockets
(upstream git commits c9b0cbe98bd783e24a8c4d8d8ac472a494b81292 and
d2286a98ef3fb88bafb57381b4c20b8b878827f1, plus updates of derived
documentation files).
Note the patch also touches html-stamp and man-stamp in doc/src/sgml/;
this is to keep the makefiles from trying to rebuild the derived doc
files. We don't want that to happen because the BuildRequires for the
package don't include the necessary documentation tools. Those diff
hunks *must be at the end* so that those files are newer than the
master doc files.
