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.)

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

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.

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.

cad9a5d11b Switched from using the ternary tree to a simple linked list. 2001-12-15 20:02:59 +00:00

75ab2c8de3 Removed the include "dnscache.h" header file. 2001-12-15 06:02:16 +00:00

a4934e2232 Added the host name lookup code (which use to be in the DNS caching 
system.)

b15be9de3e Removed the references to dnscache.c and dnscache.h 2001-12-15 05:57:40 +00:00

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.

a03a1d3847 Fixed a problem with not buffering more than 2K (which is obviously a 
problem. :)

fa193dcd22 send_message changed to send_response_message in the conn_s structure. 2001-11-25 22:08:11 +00:00

f8b61da4ae Added tests for _every_ header to make sure they are actually present on 
the system.

2f4ccc04ae Added an additional test to make sure the <regex.h> header is actually 
present on the system.

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().

8dc7035fbc Add support to limit the maximum size of the input line (to 128KB which 
should be _more_ than enough for any header line. :)

09dbdbc3d7 Change the C code to match the new style. 2001-11-25 02:20:54 +00:00

fd3b313e9f Style changes. Also replaces all mallocs with safemalloc, etc. 2001-11-23 01:18:43 +00:00

1fa9d257c2 Replaced the calls to the old readline() function with calls to the new 
version.
 2001-11-22 00:19:45 +00:00

d08d088d4a Replaced the readline() function with a new version which has no 
restrictions on the length of a line (unless you fill memory of course.)
Reformated the source.

a30eb425e3 #if 0'd the code handling the "Via" header in the process_client_headers() 
function since I'm not completely happy with the code.

bc8c3ff399 Include the protocol variables in the conn_s structure. 2001-11-21 01:00:09 +00:00

90ee7e01ca Extract the version from the request line and store it in the conn_s 
structure.
Don't send a Connection header to the remote connection.
Handle the Via header correctly.

dde4e9adcc Changed the read() call into a recv() call with a flag of NOSIGNAL since I 
don't want signals messing up my calling conventions.

ddb002d57e Replaced all calls to buffer_size() with the macro BUFFER_SIZE(). 2001-11-05 15:23:34 +00:00
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.

e61424a7bf Informing the user of the connection to the tunnel is a INFO type message, 
not a CONN level message.

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.)

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

f8ad0dced3 Moved the connection creation/destruction and definition into it's own 
files.

1bbf32f04c Fixed the problems with sending/not sending headers so that the CONNECT 
(SSL) method would work with upstream proxying!

28b4477f48 Added the upstream flag to the conn_s structure. 2001-10-25 05:10:57 +00:00

5f8ee4fae3 Bit of source code clean up. 2001-10-25 05:10:32 +00:00

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. :)

f8d43bd423 Lowered the size of the read buffer to 2K since Ethernet seems to work 
with 1400 byte segments.

a746b9d0b2 Moved the zero-length string setting to outside the tests in getpeer_*() 
functions. Also added a more robust error reporting for DNS errors.
