Looks like I spoke too soon on the Leopard upgrade.
Everything is fine now, but today saw two mini crises:
1) I composed a message to Dave, our IT guy, to let him know the upgrade went well. I hit send and… got a message from Mail.app that my message couldn’t be sent. Long story short, Leopard was setting my hostname to Macintosh. Since this is not a fully qualified hostname, the OSAF SMTP server rejected my messages outright. The fix was to set up my home network’s domain name and restart.
2) Once that was ironed out I started in on a long overdue bug. Once I finished it I merged it to the remote SVN tracking branch as usual and typed “git svn dcommit” to ship it out. To my horror I was rewarded with:
Percent_expand: NULL replacement
Network connection closed unexpectedly: Connection closed unexpectedly at /opt/local/bin/git-svn line 1005
Turns out this is a bug in the MacPorts SSH library that git-svn uses to connect to our Subversion server. A fix that worked beautifully can be found here.
