2002-04-28Added more error checking in process_client_headers() andRobert James Kaes1-34/+68
process_server_headers() functions. Also, better reporting of errors back to the client.
2002-04-26Changed the len type to ssize_t because we need to detect errors in theRobert James Kaes1-2/+2
recv() call. Thanks to Tom Cross for discovering this bug.
2002-04-26Need to check the return value of hashmap_first() since it could beRobert James Kaes1-24/+26
negative.
2002-04-25Check to see if request->path is actually allocated before trying to freeRobert James Kaes1-2/+8
it.
2002-04-25First change all the hashmap related calls to use the new API.Robert James Kaes1-47/+57
The remove_connection_headers() function now handles both the Connection header _and_ the Proxy-Connection header.
2002-04-24Fixed a couple of problems where tinyproxy was trying to free a memoryRobert James Kaes1-4/+7
block which had not been allocated. Also, the "proxy-connection" to the list of headers we don't pass.
2002-04-22Added the "Proxy-Connection" header to the list of client headers whichRobert James Kaes1-1/+2
are not passed along.
2002-04-18The stats now wait until after the client has finished sending all itsRobert James Kaes1-7/+11
headers before sending the HTTP response back. This should be more standards compliant.
2002-04-18Fixed a memory leak in reading in headers from the client or server.Robert James Kaes1-4/+12
2002-04-17If the initialize_conn() function fails, close the socket and return.Robert James Kaes1-3/+5
Also, changed the call to check_acl() to include the peer's IP and string addresses.
2002-04-16Various code clean up. There is nothing new here, just mechanical changesRobert James Kaes1-67/+43
to the source to either remove code which is not needed, or consolidate common code into a common section.
2002-04-15Changed the variable type in read_request_line() to an unsigned variableRobert James Kaes1-2/+2
in order to detect negative returns.
2002-04-15Changed the error boolean flag into a pointer to an error string and anRobert James Kaes1-16/+17
error code. We're storing this information because tinyproxy doesn't output the error information until _after_ the client has sent it's information.
2002-04-12Added code to support the new ConnectPort directive which is needed toRobert James Kaes1-1/+72
improve security of the tinyproxy system. This new directive allows the admin to block CONNECT methods to illegal ports.
2002-04-12Added a write_via_header() function which is now used in both headerRobert James Kaes1-40/+67
processing functions. Also, added a list of headers to drop in the process server header functions.
2002-04-11Did a bit of consolidation by moving code into remove_connection_headers()Robert James Kaes1-37/+106
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.
2002-04-09Removed the compare_header() function since it's been replaced by a callRobert James Kaes1-15/+7
the anonymous_search(). Added a few more log_message() calls to better explain error conditions. Fixed up a problem with X-Tinyproxy sending logic.
2002-04-07A _tonne_ of changes. It would almost be easier to just read the sourceRobert James Kaes1-163/+228
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.
2001-12-24Moved write_message() into sock.c because I'm using it in other places.Robert James Kaes1-53/+1
2001-12-23Cleaned up the code which sends the "Via" header. It now usesRobert James Kaes1-29/+24
write_message().
2001-12-20Created the CHECK_CRLF() macro to handle the tests for the appropriateRobert James Kaes1-6/+8
control characters in a string.
2001-12-19Removed duplicate code from process_server_headers() and removed the callsRobert James Kaes1-12/+9
to strlen(); readline() already returns the length of the string, so use that instead.
2001-12-19Damn---removed the debugging code from write_message().Robert James Kaes1-3/+1
2001-12-19Opps! Fixed a problem with negative numbers. :)Robert James Kaes1-3/+5
2001-12-19Redefined HTTP_LINE_LENGTH to be based on MAXBUFFSIZE (and set to aroundRobert James Kaes1-80/+118
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.
2001-12-18Updated the list of headers to ignore.Robert James Kaes1-3/+6
2001-12-17Added the code to log the request when in tunnelling mode.Robert James Kaes1-2/+22
2001-12-17Added UPSTREAM_CONFIGURED() macro to help clean up the code.Robert James Kaes1-89/+100
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.)
2001-11-23Removed the trim() function and move it into chomp()/utils.cRobert James Kaes1-44/+16
2001-11-22Reformated text.Robert James Kaes1-91/+163
2001-11-22Replaced the calls to the old readline() function with calls to the newRobert James Kaes1-22/+18
version.
2001-11-21#if 0'd the code handling the "Via" header in the process_client_headers()Robert James Kaes1-3/+25
function since I'm not completely happy with the code.
2001-11-21Extract the version from the request line and store it in the conn_sRobert James Kaes1-9/+44
structure. Don't send a Connection header to the remote connection. Handle the Via header correctly.
2001-11-05Replaced all calls to buffer_size() with the macro BUFFER_SIZE().Robert James Kaes1-7/+7
2001-11-02Informing the user of the connection to the tunnel is a INFO type message,Robert James Kaes1-2/+2
not a CONN level message.
2001-10-25Some code clean up due to the creation of the conns.{c,h} files which nowRobert James Kaes1-33/+2
store the creation/destruction and definition of the connection structure.
2001-10-25Fixed the problems with sending/not sending headers so that the CONNECTRobert James Kaes1-15/+9
(SSL) method would work with upstream proxying!
2001-10-25Changed the way relay_connection() works by having the both buffersRobert James Kaes1-22/+42
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. :)
2001-10-24Error message cleanup to make the information more informative.Robert James Kaes1-11/+11
2001-10-22Cleaned up the code in handle_connection() and added a NULL pointer testRobert James Kaes1-18/+21
in the free request function.
2001-10-19More moving around of the source code. Still can't get CONNECT to workRobert James Kaes1-53/+61
with an upstream proxy.
2001-10-17Trying to allow CONNECT methods through an Upstream proxy.Robert James Kaes1-18/+33
2001-09-16Moved the safe_read() and safe_write() functions into the sock.c fileRobert James Kaes1-144/+136
since they're now used in other places. Added support for a true upstream proxy connection. This involved some rewriting of the handle_connection() function and some of the support functions so that they do perform the domain filtering and anonymous filtering while still connecting to the upstream proxy. I think the code should be cleaned up further.
2001-09-15Removed the log messages related to memory allocation.Robert James Kaes1-20/+48
Move the SSL response header into into own function. Added support for the status host.
2001-09-14Finally got the SSL problem fixed. We can not send _any_ client headersRobert James Kaes1-4/+10
(including the new line) to the origin server when in tunnelling mode. SSL now works correctly. Yeah.
2001-09-14Changed the buffer pointer in safe_write() to be const void* since we'reRobert James Kaes1-33/+20
not changing the values. Instead of building a new request and memory, simply send each part separately. Actually uses less memory _and_ less code.
2001-09-14Massive changes. Split process_method() into a bunch of smaller files andRobert James Kaes1-192/+299
changed the parsing code from REGEX and uri.c to a simplier sscanf() method. Also, include code to handle SSL connections, but that's not quite working yet.
2001-09-12Fixed memory leak.Robert James Kaes1-2/+2
2001-09-11Switched the memory allocation for the large strings to heap based insteadRobert James Kaes1-6/+42
of stack based.
2001-09-08Changed all the mallocs and callocs to use the new safemalloc andRobert James Kaes1-6/+6
safecalloc.
