Devdraw error when starting acme

[Ethan Burns]

Hi Everyone,

Has anyone seen this error when trying to start acme:

$ acme

acme: exec devdraw: Required key not available

acme: can't open display: muxrpc: unexpected eof

Occasionally after a reboot I get it every time that I try to start acme.  The only way that I've found to fix it is to re-run ./INSTALL, but it's frustrating to wait for a reinstall before I can open my editor again.  I'd really appreciate any help.

Best,

Ethan

When it happens, can you run 'devdraw' by itself?

I'll try next time it comes up, but it may not be for a while (I don't restart unless I have to).  My recollection from last time it happened is that I could not run devdraw, but I don't recall what the error message was, if I got one.

Looks exec.c:1579 may be printing the the errno string for ENOKEY, which is frustratingly hard to find the meaning of, except it *might* be related to some kind of encryption… Do you have filesystem encryption enabled or anything like that?

[Russ Cox]

My guess is that you have something that requires a key (for example, Kerberized NFS) in your $PATH before $PLAN9/bin, the key has expired, and so the search for devdraw gets ENOKEY in that directory before finding the real devdraw in $PLAN9/bin. While waiting for ./INSTALL to run, you do other work and incidentally authenticate to whatever file system needs the key. Then the next time, the lookup sees ENOENT instead and the path search does make it down to $PLAN9/bin.

Hi Russ,

Yes.  I just verified that this is the case.  Thanks for your help.
