2002-04-18Changed all calls to strdup to safestrdup. This should provide betterRobert James Kaes4-9/+9
memory usage tracking.
2002-04-18Fixed a memory leak in reading in headers from the client or server.Robert James Kaes1-4/+12
2002-04-18Replaced the explicit header includes with one call to tinyproxy.h. Also,Robert James Kaes2-53/+30
added the utils.h header and changed all the malloc, calloc, free, and strdup to the appropriate safe variety.
2002-04-18Added the debuggin_strdup() function and the associated safestrdup()Robert James Kaes2-5/+43
macro. Also, added asserts to the other debugging_* functions.
2002-04-18Moved the filter_destroy() logic from inside the signal handler. It's nowRobert James Kaes1-6/+6
been moved to inside the main() function.
2002-04-18Moved the log rotation code out of the signal handler and into it's ownRobert James Kaes5-55/+86
function. The signal handler now simply sets a flag which is monitored inside the thread_main_loop() function. The log rotation code has also been tightened to handle any error conditions better. Credit to Petr Lampa for suggesting that system functions inside of a signal handler is bad magic.
2002-04-17Removed the LOOKUP_LOCK() and LOOKUP_UNLOCK() macros since I believe IRobert James Kaes1-12/+4
need locking around both gethostbyname() and gethostbyaddr() at the same time.
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.
2002-04-17Removed the close(connfd) call since the socket has already been closedRobert James Kaes1-9/+32
from within the handle_connection() function. Added tests to make sure pthread_create() succeeds. Added defined tests for pthread_cancel() since it's not available on all platforms.
2002-04-17Changed the check_acl() function to require the peer IP address and stringRobert James Kaes2-13/+7
address from the calling function.
2002-04-16Removed the duplicate calls to strlen().Robert James Kaes1-5/+4
2002-04-16Tightened the lookup_domain() function.Robert James Kaes1-3/+2
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.
2002-04-16Cleaned up the return values of the two anonymous functions to make theRobert James Kaes1-9/+7
code cleaner and smaller.
2002-04-15Added a test to make sure the "whole_buffer" could be allocated.Robert James Kaes1-3/+5
2002-04-15Changed the variable type in read_request_line() to an unsigned variableRobert James Kaes1-2/+2
in order to detect negative returns.
2002-04-15Added an assert() call to detect design errors.Robert James Kaes1-2/+6
2002-04-15Changed the error boolean flag into a pointer to an error string and anRobert James Kaes5-28/+54
error code. We're storing this information because tinyproxy doesn't output the error information until _after_ the client has sent it's information.
2002-04-13Added additional error handling for the bind() and listen() system callsRobert James Kaes1-3/+11
when setting up the listening socket.
2002-04-13Modified the opensock() function to respect the Listen directive. If it'sRobert James Kaes1-1/+17
set, bind all outgoing addresses to this local address.
2002-04-12Added code to support the new ConnectPort directive which is needed toRobert James Kaes2-2/+74
improve security of the tinyproxy system. This new directive allows the admin to block CONNECT methods to illegal ports.
2002-04-12Added the support code to process a ConnectPort configuration directive.Robert James Kaes2-2/+6
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.
2002-04-11Added the remote_content_length variable to store the number of bytes theRobert James Kaes2-2/+7
remote server is supposed to be transmiting to the client.
2002-04-10Removed the dependency on LIBOBJS and instead use the ADDITIONAL_OBJECTSRobert James Kaes1-7/+5
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.
2002-04-10Added an extra new line at the end of the file to quiet picky compilers.Robert James Kaes1-2/+2
:)
2002-04-09The malloc/free functions should be in stdlib.h, but if we can't findRobert James Kaes1-4/+5
stdlib.h then try including malloc.h. Maybe this will allow clean compiling on some platforms.
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.
2002-04-09Added more include logic code to be more portable.Robert James Kaes1-2/+7
2002-04-09Replaced the internally used linked list with a call to the hashmapRobert James Kaes1-58/+23
module. Code reuse is a good thing.
2002-04-09James Flemer cleaned up the make_netmask() function to remove the staticRobert James Kaes1-15/+3
table. Very nice.
2002-04-09Cleaned up the include lines to be slightly more portable (I hope.)Robert James Kaes2-5/+6
2002-04-09Added the cancelation setting to make sure the thread stops immediately.Robert James Kaes1-1/+4
2002-04-08Just moved the looping code from main() into thread_main_loop().Robert James Kaes2-21/+28
2002-04-07Just a variable name change to make it easier to read.Robert James Kaes1-2/+2
2002-04-07Updated the copyright notice.Robert James Kaes1-2/+2
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.
2002-04-07Update the list of source code files to include the vector and hashmapRobert James Kaes1-6/+8
files.
2002-04-07Cleaned up some of the code to handle errors better. Also, a little bitRobert James Kaes2-10/+56
easier to read in the variable department.
2002-04-07A hashmap implementation. I use this for storing the headers from theRobert James Kaes2-0/+491
client.
2002-04-07Added the vector module which is a vector implementation. I use it in theRobert James Kaes2-0/+276
hashmap implementation.
2002-04-02Added define check for XTINYPROXY_ENABLE. Although, I'm not sure if thisRobert James Kaes1-2/+9
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.
2002-01-25Added code to check for "errors" from the accept call in thread_main() andRobert James Kaes3-3/+28
also a new thread_kill_threads() function which should cancel all threads when the main thread is being closed.
2002-01-08Added code which checks to see if the user has signalled that tinyproxyRobert James Kaes1-8/+13
should be closed.
2001-12-28Removed an unused header.Robert James Kaes1-4/+1
2001-12-28Check for errors returned by the accept() function.Robert James Kaes1-1/+10
2001-12-24Changed send_http_message() to use the write_message() function.Robert James Kaes1-34/+49
Changed httperr() to use the same concept as the write_message() function. Still haven't figured out how to combine the code.
2001-12-24Added the write_message() function (from reqs.c)Robert James Kaes2-2/+55
2001-12-24Moved write_message() into sock.c because I'm using it in other places.Robert James Kaes1-53/+1
