Included the basic grammar and handler functions for the "upstream" and
"no upstream" directives. I still need to update the grammar to match
_all_ the possibilities documented in the tinyproxy.conf file, but at
least it now does as much as the old config parser.
Moved the reverse proxy code from reqs.c into it's own files
(reverse_proxy.c). The code in reqs.c is way too complicated, so I
want to move unrelated code into their own files to simplify the main
concepts in reqs.c.
I re-indented the source code using indent with the following options:
indent -kr -bad -bap -nut -i8 -l80 -psl -sob -ss -ncs
There are now _no_ tabs in the source files, and all indentation is
eight spaces. Lines are 80 characters long, and the procedure type is
on it's own line. Read the indent manual for more information about
what each option means.
Changed the variable type for the namelen variable to the correct
socklen_t type. The configure script already checked for it, but for
some reason I never got around to actually using it in this function.
tinyproxy does not prompt for any proxy information from the client, it
should not be eating the proxy headers. They are most likely needed by
an upstream proxy.
Changed the internal implementation of the hashmap to maintain the
insert order if the same key is repeated. The insertion is still
constant since we keep track of the head and tail of the bucket
chain.
TP_ARG_ENABLE macro. Except for the transparent proxy option, all the
other options remain identical. To enable transparent proxy support
use only --enable-transparent, rather than the old
--enable-transparent-proxy.
directory, so inform autoconf of this (the AC_CONFIG_AUX_DIR and
AC_CONFIG_MACRO_DIR macros.)
Also added a bunch of portability tests discovered by autoscan.
connptr->server_fd variable and moved it into an assert since we
should never be called with invalid data. Also made the function an
inline function since it's only called in one place.
to handle IPv6 style addresses along with the existing IPv4 and string
addresses. In addition, the hand-rolled "list" code has been replaced
with a vector (code reuse.) Also, the code should be a little easier
to understand (relatively speaking.)
I do need to add some kind of testing framework (in general) to check
that the new code does work with all the formats that will be thrown
at it.
This allows tinyproxy to respond to a request bound to the same
interface that the request came in on. As Oswald explains:
"attached is a patch that adds the BindSame option. it causes
binding an outgoing connection to the ip address of the respective
incoming connection. that way one can simulate an entire proxy farm
with a single instance of tinyproxy on a multi-homed machine."
Cool.
properly. (The sizeof "struct stat" was being used rather than the
proper "struct stat_s". On my system, "struct stat" is 88 bytes long,
while "struct stat_s" is 20 bytes long. Quite a difference!)
