4b7de22999 Added a test to make sure the "whole_buffer" could be allocated. 2002-04-15 04:16:01 +00:00

550145d49e Changed the variable type in read_request_line() to an unsigned variable 
in order to detect negative returns.

f0b6861998 Added an assert() call to detect design errors. 2002-04-15 04:13:14 +00:00

a5d3212751 Changed the error boolean flag into a pointer to an error string and an 
error code.  We're storing this information because tinyproxy doesn't
output the error information until _after_ the client has sent it's
information.

c86d22226f Added additional error handling for the bind() and listen() system calls 
when setting up the listening socket.

be47c1791d Modified the opensock() function to respect the Listen directive. If it's 
set, bind all outgoing addresses to this local address.

ecb249f424 Added code to support the new ConnectPort directive which is needed to 
improve security of the tinyproxy system.  This new directive allows the
admin to block CONNECT methods to illegal ports.

660e4d5687 Added the support code to process a ConnectPort configuration directive. 2002-04-12 16:59:37 +00:00

f1a451faea Added a write_via_header() function which is now used in both header 
processing functions.  Also, added a list of headers to drop in the
process server header functions.

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compiled (to make sure it doesn't get out of date), but it will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.

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

eb78e5e1f4 Added the cancelation setting to make sure the thread stops immediately. 2002-04-09 00:37:43 +00:00

0d66719c5a Just moved the looping code from main() into thread_main_loop(). 2002-04-08 21:35:10 +00:00

bf82c863bc Just a variable name change to make it easier to read. 2002-04-07 21:37:07 +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.

5e9aa90009 Update the list of source code files to include the vector and hashmap 
files.

97a72783f5 Cleaned up some of the code to handle errors better. Also, a little bit 
easier to read in the variable department.

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.

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

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

388920bc53 Added code which checks to see if the user has signalled that tinyproxy 
should be closed.

ea0d956a57 Removed an unused header. 2001-12-28 22:31:12 +00:00

a0dee6c57f Check for errors returned by the accept() function. 2001-12-28 22:29:11 +00:00

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

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

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

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

e964cf0d35 Damn---removed the debugging code from write_message(). 2001-12-19 05:20:01 +00:00

5140f01d5c Opps! Fixed a problem with negative numbers. :) 2001-12-19 05:19:03 +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.

17103bf8fe Updated the list of headers to ignore. 2001-12-18 05:01:03 +00:00

faf655c5db Added the code to log the request when in tunnelling mode. 2001-12-17 19:10:56 +00:00

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.)
