Marco Ivaldi pointed me to some unsafe code in ParseJob.c. I do not
have a sun machine (well, not currently operational anyway), so the
code is not tested. But seriously, this is some horrible code. This
local parser for sun needs to be rewritten!
Disable binding a privileged client port with rresvport() on Linux
systems using the musl C library, where that function is
unsupported. If there is a need for XPrint support, a BSD-licensed
implementation of rresvport() is available in the portable edition of
OpenSSH.
When using a non C locale such as fr_FR.ISO8859-1, the CUPS messages
returned by lpq are translated. However, the parser in ParseJobs.C can only
handle messages in English. As a result, dtprintinfo exits immediately with
an error message. To fix that problem we force a LANG=C environment when calling
lpq so that messages will be in English and will be processed correctly by dtprintinfo
parser.
Use /usr/local/bin/lpq from CUPS for FreeBSD
for now; this prevents immediate dtprintinfo
crash.
In the future we should handle both built-in
/usr/bin/lpq as well as CUPS /usr/local/bin/lpq
output in separate functions.
Code to support CUPS should probably shared between
other operating systems.
