Update from r60 to [almost] Go 1.
A lot is still broken, but most stuff at least compiles now.
The directory tree has been rearranged now too. Go libraries are now
under "pkg". Fully qualified, they are e.g. "camlistore.org/pkg/jsonsign".
The go tool cannot yet fetch from arbitrary domains, but discussion is
happening now on which mechanism to use to allow that.
For now, put the camlistore root under $GOPATH/src. Typically $GOPATH
is $HOME, so Camlistore should be at $HOME/src/camlistore.org.
Then you can:
$ go build ./server/camlistored
... etc
The build.pl script is currently disabled. It'll be resurrected at
some point, but with a very different role (helping create a fake
GOPATH and running the go build command, if things are installed at
the wrong place, and/or running fileembed generators).
Many things are certainly broken.
Many things are disabled. (MySQL, all indexing, etc).
Many things need to be moved into
camlistore.org/third_party/{code.google.com,github.com} and updated
from their r60 to Go 1 versions, where applicable.
The GoMySQL stuff should be updated to use database/sql and the ziutek
library implementing database/sql/driver.
Help wanted.
