B command doesn't open a file

[rjkroege]

The B command failed to open anything.

Console output (possibly suspect) at roughly the same time:

9pserve: announce unix!/tmp/ns.rjkroege.:0/acme: Address already in use
acme: can't post service: 9pserve failed

No plumber support yet. Will add that next.

8074242 adds rudimentary support.
But there's a bunch of caveats:

• the executable must be called acme
• It must open a socket called acme [as we do]. Calling it edwood breaks too much of the ecosystem.
• It must be on the path in the right spot for the plumber to see it.
  The right way to proceed is probably to call our project acme.

[rjkroege]

The plumber already supports sam and acme via config file. It ought to be easily configured to use edwood. edwood definitely needs to mount itself as acme.

[rjkroege]

In particular, so long as edwood is in the path, then

9p read plumb/rules  | sed 's/acme/edwood/' | 9p write plumb/rules

[rjkroege]

will make B work. It broke my plumbing config in other ways though for reasons having nothing to do with edwood.

[rjkroege]

Some other plumbing stuff however requires fixing:

Unimplemented: main.plumbshow(0xc4203cb740): /Users/rjkroege/tools/gopkg/src/github.com/rjkroege/edwood/look.go:252 +0x20

[paul-lalonde]

Yep. Known still undone - there's a reason I didn't close this :-)

All working now, I think, as of d314d43
