85a82af5f5 Did a bit of consolidation by moving code into remove_connection_headers() 
and added the get_content_length() function.

The process_server_headers() function was rewritten to remove the
Connection header correctly, and also retrieve the Content-Length value.
This value is needed in the relay_connection() function since there are
some remote machines which do not properly close down the connection once
the body has been retrieved.  Thanks to James Flemer for finding a test
case for this problem.

ce06f27a35 Added the remote_content_length variable to store the number of bytes the 
remote server is supposed to be transmiting to the client.

abdfa8b2da Removed the dependency on LIBOBJS and instead use the ADDITIONAL_OBJECTS 
variable in conjunction with _DEPENDENCIES and _LDADD.  The change here
makes filter a "required" module in the sense that it will always be
compiled (to make sure it doesn't get out of date), but it will
conditionally included in the object file.

a903b6d997 Added an extra new line at the end of the file to quiet picky compilers.

4fa5cef491 The malloc/free functions should be in stdlib.h, but if we can't find 
stdlib.h then try including malloc.h.  Maybe this will allow clean
compiling on some platforms.

eef4559783 Removed the compare_header() function since it's been replaced by a call 
the anonymous_search().

Added a few more log_message() calls to better explain error conditions.

Fixed up a problem with X-Tinyproxy sending logic.
 2002-04-09 20:06:24 +00:00

0c5bd57698 Added more include logic code to be more portable. 2002-04-09 20:05:15 +00:00
Robert James Kaes
7409281e34 Replaced the internally used linked list with a call to the hashmap 
module.  Code reuse is a good thing.

3c631c6e5c James Flemer cleaned up the make_netmask() function to remove the static 
table.  Very nice.
 2002-04-09 19:11:09 +00:00

2f54303d98 Cleaned up the include lines to be slightly more portable (I hope.) 2002-04-09 16:28:13 +00:00

1d52d9d510 Updated the copyright notice. 2002-04-07 21:36:39 +00:00

fb736ec3fb A _tonne_ of changes. It would almost be easier to just read the source 
itself to find out all the changes.  Changed the process_client_header()
function to use the hashmap and vector modules.  I've made this change to
better handle the Connection header.  The Connection header, it it's
present, lists all the headers which should _not_ be transmitted any
further along.  An HTTP/1.1 proxy must respect this.

Other changes are basically cosmetic.
 2002-04-07 21:35:59 +00:00

5e9aa90009 Update the list of source code files to include the vector and hashmap 
files.
 2002-04-07 21:33:38 +00:00

97a72783f5 Cleaned up some of the code to handle errors better. Also, a little bit 
easier to read in the variable department.
 2002-04-07 21:32:01 +00:00

5b3658b122 A hashmap implementation. I use this for storing the headers from the 
client.
 2002-04-07 21:30:02 +00:00
Robert James Kaes
54f369a734 Added the vector module which is a vector implementation. I use it in the 
hashmap implementation.
 2002-04-07 21:29:23 +00:00

e70b98252a Added define check for XTINYPROXY_ENABLE. Although, I'm not sure if this 
is the correct way to do this, since grammar.c probably doesn't get
recomplied even if config.h is changed.  Must look into this more.
 2002-04-02 17:17:30 +00:00
Robert James Kaes
1819c0f818 Added code to check for "errors" from the accept call in thread_main() and 
also a new thread_kill_threads() function which should cancel all threads
when the main thread is being closed.
 2002-01-25 00:01:45 +00:00
Robert James Kaes
388920bc53 Added code which checks to see if the user has signalled that tinyproxy 
should be closed.

a0dee6c57f Check for errors returned by the accept() function. 2001-12-28 22:29:11 +00:00
Robert James Kaes
9520866ab3 Changed send_http_message() to use the write_message() function. 
Changed httperr() to use the same concept as the write_message() function.
Still haven't figured out how to combine the code.
 2001-12-24 00:02:32 +00:00
Robert James Kaes
b10221fa07 Added the write_message() function (from reqs.c) 2001-12-24 00:01:32 +00:00
Robert James Kaes
475e526a48 Moved write_message() into sock.c because I'm using it in other places. 2001-12-24 00:01:02 +00:00

831b00dc7a Made the error message regarding the Idle timeout more verbose, and 
changed the level to WARNING.
 2001-12-23 22:00:36 +00:00
Robert James Kaes
c3124815a1 Cleaned up the code which sends the "Via" header. It now uses 
write_message().
 2001-12-23 21:55:08 +00:00

b68354a9da Add a pre-processor test around the sys/types.h header file, to make sure 
it's available before we try to include it.
 2001-12-23 18:44:02 +00:00

4ed73b6f07 Fixed up the order of some of the includes to cope with OpenBSD. Also, 
test for the MSG_NOSIGNAL define.

93f0406b7e Created the CHECK_CRLF() macro to handle the tests for the appropriate 
control characters in a string.
 2001-12-20 04:48:32 +00:00
Robert James Kaes
7240af4333 Changed the calls to write() to send() so that we can use send(..., 
MSG_NOSIGNAL) and not get signals sent to the process. (easier for
debugging and the system doesn't need to worry about signals.)
 2001-12-19 20:41:28 +00:00
Robert James Kaes
63a1fa96cc Removed duplicate code from process_server_headers() and removed the calls 
to strlen(); readline() already returns the length of the string, so use
that instead.
 2001-12-19 20:40:23 +00:00
Robert James Kaes
e964cf0d35 Damn---removed the debugging code from write_message(). 2001-12-19 05:20:01 +00:00

56b541d76b Redefined HTTP_LINE_LENGTH to be based on MAXBUFFSIZE (and set to around 
16 KB.)

Added the TUNNEL_CONFIGURED() macro to help with testing for the tunnel
support code.

Create the write_message() function to encapsulate the code which sends
the information to the file descriptor.

Moved the tunnel code into it's own function.
 2001-12-19 05:13:40 +00:00

17103bf8fe Updated the list of headers to ignore. 2001-12-18 05:01:03 +00:00
Robert James Kaes
faf655c5db Added the code to log the request when in tunnelling mode. 2001-12-17 19:10:56 +00:00
Robert James Kaes
9448787ff2 Added UPSTREAM_CONFIGURED() macro to help clean up the code. 
Ignore any blank lines when tinyproxy is expecting a request line.

Instead of sending the request line to the remote server in pieces,
tinyproxy nows sends it in once go. This was done to fix a problem with
some sites like www.heise.de.

Changed all calls to connptr->ssl to connptr->connect_method.

Changed all calls to connptr->send_message to
connptr->send_response_message.

Moved the call to Via header code to inside to the tests to handle if
tinyproxy is sending an error message (don't need to send any headers.)
 2001-12-17 00:11:32 +00:00

fdb4952e5f Added the assert() calls to safe_write() to make sure the arguments are 
sane.

6919faea77 Removed reference to ternary.h 2001-12-15 20:08:24 +00:00
Robert James Kaes
997d3daa65 No longer need this system since it was only being used in the DNS caching 
section and the anonymous header section. Once I had removed the DNS
caching, the ternary tree system was overkill for the anonymous header
code. Replaced in the anonymous header section with a simple linked list.
 2001-12-15 20:07:45 +00:00
Robert James Kaes
b969ed4302 Changed safe_write() to fully send all the data in the buffer it was 
passed. Also safe_write() and safe_read() now use char pointer buffers
rather than the void pointer style.

a4934e2232 Added the host name lookup code (which use to be in the DNS caching 
system.)
 2001-12-15 05:58:30 +00:00
Robert James Kaes
b15be9de3e Removed the references to dnscache.c and dnscache.h 2001-12-15 05:57:40 +00:00
Robert James Kaes
bf18ec5adc Removed the DNS caching system because tinyproxy did not determine the TTL 
of the host names being resolved, which is not recommended by RFC2616.
Basically, if a HTTP client doesn't respect the TTL is should not be
caching the address since it leaves itself open to DNS spoofing attacks.

Also, having a DNS caching system is an administater decision, and so
should not be included in the tinyproxy source.

Robert James Kaes
e9cfd1f82e makenewline() now copies the data into the structure rather than just 
storing the pointer to the data.
add_to_buffer() is now exported.
Renamed writebuff() and readbuff() to write_buffer() and read_buffer().

dde4e9adcc Changed the read() call into a recv() call with a flag of NOSIGNAL since I

Robert James Kaes
270af08171 Removed the buffer_size() function and turned it into BUFFER_SIZE() macro. 
Moved the struct buffer_s into the header file. Added more assert() calls
to better document the assumptions the functions make. Removed incorrect
code in remove_from_buffer() which was never actually called anyway.

4ac03908fc Header reorganization. Basically all system headers are now included in 
tinyproxy.h and all the other files include the tinyproxy.h header. This
moves all the dependancy issues into one file.
 2001-10-25 17:27:39 +00:00
Robert James Kaes
722a7d2142 Changed the included headers to be only the "tinyproxy.h" since it 
contains all the code for properly bringing in the system headers (in the
correct order and with proper dependancies.)
 2001-10-25 17:02:50 +00:00
Robert James Kaes
d3b099140f Some code clean up due to the creation of the conns.{c,h} files which now 
store the creation/destruction and definition of the connection structure.
 2001-10-25 16:58:50 +00:00

1bbf32f04c Fixed the problems with sending/not sending headers so that the CONNECT 
(SSL) method would work with upstream proxying!
 2001-10-25 05:12:46 +00:00

5f8ee4fae3 Bit of source code clean up. 2001-10-25 05:10:32 +00:00
Robert James Kaes
6afa56ba09 Changed the way relay_connection() works by having the both buffers 
emptied when either socket is closed. This should be better for the tunnel
connections.
Change the connect_to_upstream() function to better utilize the
establish_http_connection() function. Code re-use is cool. :)
 2001-10-25 04:40:48 +00:00

f8d43bd423 Lowered the size of the read buffer to 2K since Ethernet seems to work

b40e382e5a More moving around of the source code. Still can't get CONNECT to work

6ab7ebcb31 send_http_message() doesn't create a memory block and store it in the 
connection's output_message variable. Instead the error is sent to the
client right away. Once we finish processing the client's headers it will
automatically accept the error message. So we get the same result, but
less memory is used.
 2001-09-16 20:13:52 +00:00
Robert James Kaes
606c8196a0 Added the configure variables to support the upstream proxy. 2001-09-16 20:12:29 +00:00
