tinyproxy uses a curious mechanism to log those early messages
that result from parsing the config file before the logging mechanism
has been properly set up yet by finishing parsing of the config file:
those early messages are written into a memory buffer and then
are printed later on. this slipped my attention when making it possible
to log to stdout in ccbbb81a.
using the "BasicAuth" keyword in tinyproxy.conf.
base64 code was written by myself and taken from my own library "libulz".
for this purpose it is relicensed under the usual terms of the tinyproxy
license.
original patch submitted in 2006 to debian mailing list:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=392848%29#12
this version was rebased to git and updated by Russ Dill <russ.dill@gmail.com>
in 2015 (the original patch used a different config file format).
as discussed in #40.
commit message by @rofl0r.
if using one of unsigned or signed char for the function prototype, one
gets nasty warnings when using it with the other type. the only proper
solution is to put void* into the prototype, and then specialize the pointer
inside the function using an automatic variable.
for exactly this reason, libc functions like read(), write(), etc use void*
too.
some users want to run tinyproxy on an as-needed basis in a terminal,
without setting it up permanently to run as a daemon/service.
in such use case, it is very annoying that tinyproxy didn't have
an option to log to stdout, so the user has to keep a second terminal
open to `tail -f` the log.
additionally, this precluded usage with runit service supervisor,
which runs all services in foreground and creates logfiles from the
service's stdout/stderr.
since logging to stdout doesn't make sense when daemonized, now if
no logfile is specified and daemon mode activated, a warning is
printed to stderr once, and nothing is logged.
the original idea was to fail with an error message, though some users
might actually want to run tinyproxy as daemon and no logging at all.
some people want to run tinyproxy with minimal configuration from
the command line (and as non-root), but tinyproxy insists on writing
a pid file, which only makes sense for usage as a service, hereby
forcing the user to either run it as root so it can write to the
default location, or start editing the default config file to work
around it.
and if no pidfile is specified in the config, it frankly doesn't
make sense to force creation of one anyway.
tinyproxy conservatively defaulted to allow CONNECT method only
on two ports used by SSL in the ancient past, but since HTTPS usage
got much more widespread (actually, it's now the default for the
majority of websites), it makes sense now to allow it without
restriction by default to accomodate for the new situation.
this causes a build failure on several platforms using older versions
of autotools or GNU make.
