[9fans] nupas mk install bug

[matt]

mk install
... snip ...
cp 8.out /386/bin/nupas/Mail
cp: can't create /386/bin/nupas/Mail: '/386/bin/nupas' does not exist


works ok when I access my Courier server but aborts on

nupas/fs/fs.c:157

when I access the imap version of http://fastmail.fm/

I've tried it on two mailboxes, it does this command

9x4 uid fetch 1:* (uid rfc822.size internaldate)

then fails parsing the repsonses

of the form

* 99 FETCH (UID 32768 INTERNALDATE " 6-Feb-2009 08:52:33 -0500"
RFC822.SIZE 74193)


That's as far as I got :>

i may be wrong, but that is intentional.  i don't know of other
plan 9 programs that make their own bin when installed.

interesting.  there's nothing that looks obviously
wrong with that line.  it must already be out of step.
would you mind applying this edit

imap.c:1085,1091 - /n/sources/contrib/quanstro/src/nupas/fs//imap.c:1085,1090
  	}

  	imap = emalloc(sizeof *imap);
- 	imap->flags |= Fdebug;
  	imap->fd = -1;
  	imap->freep = path;
  	imap->flags = flags;

and sending along the debugging output?  it's going
to be a bit chatty.  thanks.

thanks for the bug report.  i signed up for fastmail.fm
to figure out what's going on.

there were two independent failures.  first, fastmail.fm
takes the unusual step of reordering the requested fields.
the response parser wasn't able to deal with that.  simple
fix.  the second problem was parsing a list of flags in the
return.  we didn't ask for flags, but fastmail sent 'em anyway.
this part of the fix seems solid, but needs a little more testing.
since it's not working for you at all, would you try
/n/sources/contrib/quanstro/src/imap.c?
replace fs/imap.c with this file and recompile.

I found one in /n/sources/contrib/quanstro/imap.c and used that and it
worked 99%

I got a panic (attached) but when I tried to reproduce it the message
had gone. It was a notice from ebay but none of my other ebay notices
would trigger it.

I big thank you.

I'll be using it daily from now on so I'll keep an eye on it.
