Summary: 

I just installed and tied together uuhosts/uumail/pathalias, and
thought I'd throw my two cents worth in

How does this work now that:

	a) some of the u.* file names are 13 or 14 chars long and compress
	   refuses to compress them?
	b) 4.0 "zcat" refuses to handle uncompressed files (so zcat u.* won't
	   work either given (a))

(we're running 4.0 compress, 1.69 uuhosts and 3.0 uumail all compiled in the
Berkeley universe on our Pyramid - they are the latest aren't they?  They
are all the latest ones I've seen on mod.sources)

I went to all of the trouble of converting uuhosts and my pathalias script
to do something like:

	for i in u.*
	do
	    f=`basename $i .Z`
	    if [ -r $f ]
	    then
		cat $f
	    else
		zcat $f
	    fi
	done | ...

But, then I saw quite a few errors coming out from pathalias and I wanted
to find out precisely where they were.

[somebody oughta fix u.usa.ca.1 and 2 - there are quite a few syntax errors 
plus lots of alias redeclarations, and for some reason "#NOTE: 0)" got 
parsed by pathalias as a site called "0)"!
Does anybody know what these mean?  Did anybody else get them?:

/usr/local/lib/pathalias: internal error on private host cs-pacx
/usr/local/lib/pathalias: internal error on private host cs-ether

The "0)" site and internal errors may very well be a porting problem.

Aren't the map files run thru pathalias before posting?]

Fortunately we have enough space to create a directory and uncompress:

>into
>
>	uncompress u.*.Z; pathalias u.*; compress -f u.*

we use:
	MAPS=/usr/spool/maps
	cp u.* $MAPS/tmp; cd $MAPS/tmp; pathalias u.*...; rm -f u.*

Other things:
	1) uumail's "address.c" has a VAXism - "int uswitch" in the main
	   function should be initialized to 0 (eg: "int uswitch = 0;"
	   - VAX's tend to initialize locals as zero.  On a Pyramid it's 
	   garbage ("address" would call opath correctly about 25% of 
	   the time and oupath the rest with the same input)
	   [We're running "class 3" by the way]
	2) uumail's uuconf.h has:

		#define NAMESIZ 32 /* system name size */
		#define NEIGHBORS  BUFSIZ/NAMESIZ

	   NEIGHBORS is used in the getpath.c declaration:
		
	        char neighbors[NEIGHBORS][NAMESIZ]; 

	   This is used to contain the names of the adjacent sites (sites
	   mentioned in L.sys).  Well, we have 71 L.sys entries and
	   BUFSIZ/NAMESIZ is 64.  Nor is there a check in getpath.c for
	   overflow... BOOM!  I changed the NEIGHBORS define to:

		#define NEIGHBORS  BUFSIZ*2/NAMESIZ

	   And added a check for overflow.
	3) Somebody oughta reparagraph uumail 3.0 (ugh!).
	4) I had to heavily modify uuhosts to work with the new naming 
	   conventions with COMPRESS turned on (see above)

After fixing these it appears to work reasonably well.

Is there going to be a new uuhosts distribution for the new naming 
convention?
