0e7182533c Need to check the return value of hashmap_first() since it could be 
negative.

6992c74bba Check to see if request->path is actually allocated before trying to free 
it.

b4ef24844f First change all the hashmap related calls to use the new API. 
The remove_connection_headers() function now handles both the Connection
header _and_ the Proxy-Connection header.

d1031e2c8f The hashmap API changed, so this function needs to be changed as well. 2002-04-25 18:56:43 +00:00

ce51a74045 Removed the hashmap_keys() function and added the "iterator" concept. 
This required a bunch of changes to the source (like the inclusion of the
end_iterator member variable.)  All this was required by sites like Yahoo
which send out multiple "Set-Cookie" headers.  tinyproxy needs to handle
this situation correctly.

b5df4f1cf0 hashmap_search() only takes two arguments, so removed the unneeded NULL. 2002-04-25 18:52:09 +00:00

d7c3f23610 bind_address has been moved inside the config structure. Fixed up a 
problem where "data" was being freed even if it had not been allocated
(because of an error condition.)

335d787018 Fixed a couple of problems where tinyproxy was trying to free a memory 
block which had not been allocated.

Also, the "proxy-connection" to the list of headers we don't pass.

89ada2df28 Moved bind_address inside the config structure. 2002-04-24 16:45:45 +00:00

c5b9ec889e Renamed the LOCKing macros and added assert debugging code. Also, moved 
the mutex initialization into a function call so that I can use an
error checking mutex once I figure out how to get it to work on my
computer.

08077cc9e1 The "Bind" directive sets a binding address which the outgoing connections 
will use.
 2002-04-22 19:35:24 +00:00

1953348c90 Added the "Proxy-Connection" header to the list of client headers which 
are not passed along.

2ec7a4dd72 The log_message() function now stores the messages if the configuration 
file has not been read yet.  The reason for this is that we don't know
where to log the messgaes until _after_ the config file has been
processed.
 2002-04-22 19:34:20 +00:00

60f61c8f0c Added the "Bind" directive. 2002-04-22 19:33:01 +00:00

aa68eb8540 Whoops. The previous include only had the code conditionally removed. 
Remove for real this time.
 2002-04-18 21:54:50 +00:00

1db154464e Removed the call to inet_aton() since the gethostbyname() function handles 
the dotted-decimal case itself.
 2002-04-18 21:53:33 +00:00
Robert James Kaes
60f0a86c75 The stats now wait until after the client has finished sending all its 
headers before sending the HTTP response back.  This should be more
standards compliant.
 2002-04-18 21:43:53 +00:00

73a53daf38 Removed the call to hstrerror() in the getpeer_string() function. It's 
not available on all machines.
 2002-04-18 18:48:22 +00:00

d14b612e13 Fixed a memory leak in the hashmap_delete function. The array of maps was 
not being deleted.
 2002-04-18 18:40:38 +00:00

9a8d732a13 Changed all calls to strdup to safestrdup. This should provide better 
memory usage tracking.
 2002-04-18 17:59:21 +00:00

a66aae880c Fixed a memory leak in reading in headers from the client or server. 2002-04-18 17:58:52 +00:00
Robert James Kaes
3b5a4b7362 Replaced the explicit header includes with one call to tinyproxy.h. Also, 
added the utils.h header and changed all the malloc, calloc, free, and
strdup to the appropriate safe variety.
 2002-04-18 17:57:20 +00:00

ce4687fbf9 Added the debuggin_strdup() function and the associated safestrdup() 
macro.  Also, added asserts to the other debugging_* functions.

43860d2469 Moved the filter_destroy() logic from inside the signal handler. It's now 
been moved to inside the main() function.
 2002-04-18 17:04:04 +00:00
Robert James Kaes
5822ec3d44 Moved the log rotation code out of the signal handler and into it's own 
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.

3e60a5b819 Removed the LOOKUP_LOCK() and LOOKUP_UNLOCK() macros since I believe I 
need locking around both gethostbyname() and gethostbyaddr() at the same
time.

1d85484c3a If the initialize_conn() function fails, close the socket and return. 
Also, changed the call to check_acl() to include the peer's IP and string
addresses.
 2002-04-17 20:55:21 +00:00
Robert James Kaes
42098699db Removed the close(connfd) call since the socket has already been closed 
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.
 2002-04-17 20:54:26 +00:00
Robert James Kaes
44bbdb2623 Changed the check_acl() function to require the peer IP address and string 
address from the calling function.

04da777bed Removed the duplicate calls to strlen(). 2002-04-16 03:22:16 +00:00

0e4436a070 Tightened the lookup_domain() function. 2002-04-16 03:21:46 +00:00

ca10b1353d Various code clean up. There is nothing new here, just mechanical changes 
to the source to either remove code which is not needed, or consolidate
common code into a common section.
 2002-04-16 03:20:43 +00:00

c722851bce Cleaned up the return values of the two anonymous functions to make the 
code cleaner and smaller.
 2002-04-16 03:19:19 +00:00

4b7de22999 Added a test to make sure the "whole_buffer" could be allocated. 2002-04-15 04:16:01 +00:00
Robert James Kaes
550145d49e Changed the variable type in read_request_line() to an unsigned variable 
in order to detect negative returns.
 2002-04-15 04:14:03 +00:00
Robert James Kaes
f0b6861998 Added an assert() call to detect design errors. 2002-04-15 04:13:14 +00:00
Robert James Kaes
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.
 2002-04-15 02:07:27 +00:00

c86d22226f Added additional error handling for the bind() and listen() system calls 
when setting up the listening socket.
 2002-04-13 19:03:18 +00:00
Robert James Kaes
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.
 2002-04-12 17:00:42 +00:00
Robert James Kaes
660e4d5687 Added the support code to process a ConnectPort configuration directive. 2002-04-12 16:59:37 +00:00
Robert James Kaes
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.
 2002-04-12 03:09:04 +00:00
Robert James Kaes
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.
 2002-04-11 20:44:15 +00:00
Robert James Kaes
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

7409281e34 Replaced the internally used linked list with a call to the hashmap 
module.  Code reuse is a good thing.
