 1.25  30-Aug-2011  joerg static, __printflike, __dead
 1.24  13-Jul-2009  roy Rename internal getline() function to get_line() so it does
conflict with the soon to be added getline(3) libc function.
 1.23  18-Jan-2009  lukem fix -Wsign-compare issues
 1.22  21-Mar-2006  christos Coverity CID 1750: Add a function to free a queue and use it.
 1.21  20-Jan-2006  christos Instead of dealing with port@host in many places, do it where it is needed.
It reduces code and complexity and at the same time allows as to use symbolic
ports instead of just numeric everywhere.
 1.20  17-Jan-2006  garbled Fix PR bin/14247
This PR claims that MacOSX 10.1 cannot print postscript files to a NetBSD
lpd because the mac will tag the file with an "o" for postscript, which
we do not handle. Rather than simply mapping o -> f as was done in the
PR, or mapping o -> l as was done in FreeBSD, I have implemented full
support for the "o" option. If a postscript filter does not exist in the
printcap file however, it will default to "l" handling.

With this change, you can now specify a "pf" or postscript filter in your
printcap, and have it handle postscript files sent to it with "lpr -o".

The "o" format in lpd is specified in RFC1179 as being a valid format flag.
 1.19  28-Nov-2005  christos - WARNS = 4
- factor out commonly used code.
- constify
- use warn/warnx instead of printf
 1.18  24-Apr-2004  christos constify printcapdb
 1.17  07-Aug-2003  agc Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22366, verified by myself.
 1.16  14-Jul-2002  wiz Unifdef __STDC__. Remove __P(). ANSIfy.
 1.15  11-Oct-2000  is More format string cleanups by sommerfeld.
 1.14  16-Apr-2000  mrg branches: 1.14.4;
make scandir(3)'s 3rd argument take a function that takes a *const*
struct dirent *, rather than non-const. this makes scandir(3) the
same as the scandir implementations in libiberty and glibc, and the
select function has no need to modify the dirent.
 1.13  07-Dec-1999  mrg - add timeouts to displayq(), rmremote(), sendfile() and response(),
and use these timeout in the lpq, lpd and lprm programs.

these stop hung remote printers that accept tcp connections but do
not process jobs from hanging the whole system and letting the sysadmin
have a clue about what is going on with this rogue printer.

- add a -r flag to lpd to allow `of' filters for remote jobs.

i know there are ways around this, but i just don't care.

- add a -f flag to lpf to add missing carriage returns.

useful when printing UNIX files to an, eg, LaserWriter that wants CR's
as well as LF's in raw text. stair-stepped text is no fun.

- implement child process accounting: we just have a limit on the number
of children we can have (settable by the sysadmin), and we sleep when
this number is reached. this can reduce malicious not-so-malicious
attacks on the print server by a rogue remote client..

- use setproctitle() where appropriate so the sysadmin has a clue about
what each of the lpd's here are doing.

this was useful to help diagnose a problem (that the above child process
accounting change reduces the lossages of) where a rogue client was
attempting "lpq" operations on one stuck queue in rapid succession,
causing the lpd server to be extremely slow, due to the large number
of lpd processes running.


i have been running these changes in production for about a year.
