Subject: Log peer address when git-daemon called from inetd
X-Git-Tag: v1.4.1-rc1~3^2~4
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=5b276ee4fb01a5c3cf4970df69d319a3c93c81c9;p=git.git

Log peer address when git-daemon called from inetd

When we run git-daemon from inetd, even with the --verbose option, it
doesn't log the peer address. That logic was only in the standalone
daemon code -- move it to the execute() function instead. Tested with
both IPv6 and Legacy IP clients, in both inetd and daemon mode.
