6ff4192069 Removed the remote_content_length field in the "conn" structure and 
replaced it with a smaller structure containing both the remote/server
and the local/client content-length fields if they're present in the
HTTP response headers.

bcf25dc67e (add_error_variable): Test whether connptr->error_variable is NULL, 
and if so call safemalloc().  This is needed since saferealloc() will
assert() if the first argument is a NULL pointer.
 2003-04-01 16:41:33 +00:00
Robert James Kaes
7cd19206cc (establish_http_connection): Always include the port number for the 
requested server.  This fixes a problem when the server is not
listening on the default port, 80.
[Fix suggested by duncan@sapio.co.uk]

63a7914830 # Moved the location of the "initializing" log message to below the 
processing of the command line options.

d2c9ffac23 Made get_html_file() and lookup_variable() static functions since they 
are only used with this file.

5faa0879ec # Added copyright notices for Steve. Reformatted the source code to 
better match the existing tinyproxy practise.  Included a few bug
  fixes from Steve.

cc90414b29 (send_http_message): Changed the function to use the new http_message 
API.
 2003-03-14 06:15:27 +00:00
Robert James Kaes
c76183a3f0 # Updated all the calls to indicate_http_error() to include a 
terminating NULL.  The va_arg() function requires it to work
  properly.

75dd0b22c4 Allow the URL for the statistic page to be controlled from the 
configuration file, rather than being hard-coded in the program.

a46bfdc2e0 Moved the send_http_error_message() and indicate_http_error() 
functions into the htmlerror.c file, and recoded them to use the new
variable substitution system. [Steven Young]

b06f26cba1 # Changed showstats() to use the HTML variable functions when 
possible.  It still retains the hard-coded page for when an HTML file
  is not available. [Steven Young]

99ec965544 # (child_main): If this is a debugging build output the child process 
ID and wait for 10 seconds so we have time to connect gdb to the
  child.  This is needed if we want to use gdb against the child
  process.

686826c3b0 An API to handle HTTP messages as concrete entities. 2003-03-13 05:25:30 +00:00
Robert James Kaes
2f9370afe7 (chomp): Fixed up the code to prevent negative array access. Added 
code to make sure the supplied arguments are valid.
 2003-03-13 05:20:06 +00:00
Robert James Kaes
20d3008c38 (main): Removed duplicate code calling the filter_destroy() function. 
Once is enough.  [Detected by John M Wright]
 2003-02-26 22:37:38 +00:00
Robert James Kaes
40c4d3c57a # (connect_to_upstream): Improved the preprocessor directives to make 
sure the function would compile cleanly regardless of how the
  directive was set.
 2003-01-28 21:21:55 +00:00

2f98fec1aa # Style clean up. 2003-01-27 18:45:25 +00:00

abbf826445 (display_usage): Removed the output line mentioning that regular 
expression support was included.  It will be there always.
 2003-01-27 18:44:43 +00:00
Robert James Kaes
2fc9c76969 (connect_to_upstream): Reorganized the preprocessor directives to make 
sure the function's symbol name is stored, even if upstream was not
compiled it.  This should keep some compilers from reporting errors.
 2003-01-27 18:42:18 +00:00

cb7e3eef04 Added support for conditionally using case sensitive filtering files. 
Code changes from James E. Flemer.
 2003-01-27 17:57:45 +00:00

212abd64d7 (process_client_headers): Fixed inverted anonymous header logic. Fix 
comes from the FreeBSD port through James E. Flemer.
 2003-01-27 17:39:02 +00:00
Robert James Kaes
59ec5dc69f (strip_username_password): New function to remove any 
username/password part from the host URI.

(extract_http_url), (extract_ssl_url): Use the new
strip_username_password function to remove any non-host information
from the URI.
 2002-12-04 17:36:48 +00:00
Robert James Kaes
0a20bdd5b4 Removed the "bool_t" type since it conflicts with the newer C standards. 
The type was just replaced by "unsigned int" types.
 2002-12-04 17:06:14 +00:00
Robert James Kaes
d069b4fce9 (extract_http_url): Removed the leading "http://" from all the tests, 
since it's skipped by the caller before the URL is passed to this
function.

(process_request): Include code to handle proxy FTP requests as
well.  This also lead to a bit of a cleanup in the calling conventions
of extract_http_url function.  tinyproxy can handle both types of
resources by skipping the leading :// part.
 2002-11-29 19:25:59 +00:00
Robert James Kaes
e58343012f Included code to disable the sending of the Via header. This is now 
controlled by the ViaHeader configure directive.
 2002-11-26 21:44:43 +00:00
Robert James Kaes
c826b18437 (child_main): Cleaned up the notice string to be more clear why a 
child is being closed.
 2002-11-21 21:54:09 +00:00
Robert James Kaes
22df8c29e4 (main): Check to see if the PID file was created successfully, and if 
not report this to the user and close the program.
 2002-11-21 21:52:59 +00:00
Robert James Kaes
48df7d401c # Changed the return type for pidfile_create() to int from void. 2002-11-21 21:52:03 +00:00
Robert James Kaes
820832a647 (create_file_safely): Rather than exiting the program if there is an 
error, a negative "error code" is returned to the program.  The
various callers then need to decide what to do.

(pidfile_create): Returns an error status depending on whether the PID
file was created successfully.
 2002-11-21 21:51:34 +00:00
Robert James Kaes
d40a4e8af7 (relay_connection): Shutdown the client socket for writing once all 
the data has been sent.
 2002-11-13 17:48:48 +00:00
Robert James Kaes
a1e24ac839 (destroy_conn): Added code to log any error messages when the sockets 
are closed.
 2002-11-13 17:47:40 +00:00
Robert James Kaes
3b2be8ae88 Removed all the code supporting the TCP tunnelling feature of 
tinyproxy.  There is really no need for this code, since there are
perfectly good programs out there (like rinetd) which are designed for
TCP tunnelling.  tinyproxy should be a good HTTP proxy, nothing more,
and nothing less; therefore, the tunnelling code is gone.
 2002-11-03 17:10:33 +00:00
Robert James Kaes
69be2b84d7 (relay_connection): Ivan pointed out a bug with the code to send any 
remaining data to the server when the connections are being closed.
It was a one line fix.
 2002-10-17 19:27:08 +00:00

1d39f204ca Fixed up the storing and sending of the internal tinyproxy logs prior 
to when the log file is created.  Also, the log file is created with
the proper owner permissions.
 2002-10-03 20:53:11 +00:00
Robert James Kaes
745c40650b #Style formatting change. 2002-10-03 20:50:59 +00:00
Robert James Kaes
942f22989a The internal log structure now uses a vector rather than a hash. This 
change was required to actually display all the logs in the correct
order.  Also, all log lines are stored internally while tinyproxy is
starting.  At the appropriate point all the logs are written to the
log file.
 2002-10-03 20:49:57 +00:00
Robert James Kaes
7fd291f407 Filtering is now case insensitive. 2002-10-03 20:40:39 +00:00
Robert James Kaes
2b44dbd7e4 #(makedaemon): Commented out the closing of the standard file 
descriptors since we need them to display error messages.
 2002-10-03 20:38:06 +00:00
Robert James Kaes
ac881909bf (child_main): Check to make sure memory could be allocated to handle 
the child request.
(child_main_loop): Added a call to truncate_log_file() when the log
file is to be rotated.
 2002-10-03 20:33:09 +00:00
Robert James Kaes
f8b5fe53e7 (main): Fixed up a bug reported by Oswald Buddenha where the log file was being initially created with the initial user's permissions, which is obviously a problem if tinyproxy is not running as the initial user. This is now fixed by delaying the creation of the log file until _after_ tinyproxy has been switched to the user it will run as. Confused yet? 2002-07-12 17:02:02 +00:00
Robert James Kaes
ab574cbec0 (create_file_safely): 
(pidfile_create): Changed all the error logging to write to standard error and then exit the program.  This will prevent segmentation fault problems from occurring because the log file could not be created properly.
 2002-07-09 19:02:57 +00:00
Robert James Kaes
4932b87fc9 (malloc_shared_memory): Changed the static character array to include the ".XXXXXX" string already. This saves one system call when creating a temporary file name. 2002-07-09 18:52:32 +00:00
Robert James Kaes
e50d0c4072 (child_make): Reset the various signals to the default signal handler so that the children can be properly destroyed. 2002-06-27 16:29:21 +00:00
Robert James Kaes
f0d7992765 (log_message): Changed the code so that the log is opened, written, and closed whenever a message is submitted. This allows the log file to be moved away, for example a rotating the log, and yet still have the information written to the correct file name by all the children. 2002-06-15 17:37:11 +00:00
Robert James Kaes
ac5d67c11a Renamed the "log_rotation_request" boolean to "received_sighup". 
(main): Removed the log file creation code because it has been moved into the log.c file.  Also, removed the explicit fclose() for the log file since it will be close when the program has exited.
 2002-06-15 17:35:03 +00:00
Robert James Kaes
8a9db93977 (child_main_loop): Moved the filter re-initiation code into the loop. This code is activated whenever the SIGHUP signal is received. 2002-06-15 17:31:31 +00:00
Robert James Kaes
fb688a2077 Removed the "logf" FILE structure from the config structure, and also renamed the "log_rotation_request" boolean to "received_sighup". 2002-06-15 17:29:59 +00:00
Robert James Kaes
2f84b170a6 Removed the rotate_log_files() function since I'm moving to an Apache style where the _user_ needs to move the log file themselves, and tinyproxy will continue to write to the original name. This allows more flexibility for users to determine their own log rotation scheme. 2002-06-15 17:28:19 +00:00
Robert James Kaes
1f2fe53c4b Added myself to the copyright since I've made a bunch of changes to this file. 2002-06-07 19:10:05 +00:00
Robert James Kaes
7e1de2012c Added code to handle the "FilterDefaultDeny" directive. The filter_set_default_policy() function is used to select the default policy (either default allow or default deny) for the filtering code. Also, the two filtering functions now support the policy code. 2002-06-07 18:36:22 +00:00
Robert James Kaes
ff56e32e8e Added the "FilterDefaultDeny" directive to allow the user to select whether the default policy of the filter is to allow everything which isn't denied, or to deny everything which isn't allowed. 2002-06-07 18:29:41 +00:00
Robert James Kaes
f47685c861 A bunch of changes from Petr Lampa that add transparent proxy support to tinyproxy. The additional code is in process_request(), but Petr also had to change around some of the other functions (like process_client_headers and handle_connection.) Note: Right now this code has not been tested, but it is believed to work. To enable run ./configure --enable-transparent-proxy 2002-06-06 20:32:30 +00:00
Robert James Kaes
0242d89877 (filter_domain): Removed code which stripped of a port number from the host name. The "host" variable will _always_ be just the name by the time filter_domain() is called. 2002-06-06 20:30:04 +00:00
Robert James Kaes
06d38ce529 (display_usage): Added a message indicating whether transparent proxy support has been compiled in. 2002-06-06 20:28:02 +00:00
Robert James Kaes
a72fc7ad09 Added a warning message to the Bind directive stating that it will be ignored if "transparent proxy" has been compiled into tinyproxy. 2002-06-06 20:26:13 +00:00
Robert James Kaes
2b5a3625bc (send_stored_logs): Actually included the code to output the stored logs. Plus, there was a bug with how I was calling the hashmap_is_end() function. This has now been fixed. 2002-06-06 20:24:21 +00:00
Robert James Kaes
e440dee245 (child_main): Added a DEBUG call to let me know which process has accepted a connection. This is needed for debugging using "gdb". 2002-06-05 17:02:15 +00:00
Robert James Kaes
89dee022e5 (malloc_shared_memory): Removed the assert() call for shared_file since it's now a static variable. 2002-06-05 17:01:09 +00:00
Robert James Kaes
b697ebf16b (acl_string_processing): Moved the string processing code out of check_acl() and into it's own function because it now does two (2) tests. If the ACL string is a complete host name, in other words doesn't start with a period, than a reverse DNS look-up is done on the host name and compared to the IP address of the client; otherwise, the normal text string comparison is done. 
(check_acl): Moved the string text out of the function and removed some logging code by jumping to the "Deny" code at the end of the function.
 2002-06-05 16:59:21 +00:00
Robert James Kaes
02f3bdf5ff Added a boolean "truncate_file" flag for the create_file_safely() function. 2002-05-31 18:27:13 +00:00
Robert James Kaes
833186b7be (create_file_safely): Added the "truncate_file" boolean flag. This is needed since I use this function for both the log file and the pid file, and they behave differently when tinyproxy is started. 
(pidfile_create): Call create_file_safely() with a TRUE "truncate_file" flag so that the file is emptied whenever the pid file is needed.
 2002-05-31 18:26:30 +00:00
Robert James Kaes
e340b3371b The log file is now opened in "append" mode so that you can restart tinyproxy without losing the log file. 2002-05-31 18:24:36 +00:00
Robert James Kaes
26a983b467 (process_server_headers): Since we're stripping off the carriage return and newline, we need to add them back on when sending the response header to the client. 2002-05-31 18:09:09 +00:00
Robert James Kaes
f548ce72b2 (getpeer_information): Fixed a problem retrieving the FQDN of a host because I was passing in an incorrect parameter to gethostbyaddr(). D'oh. 2002-05-31 18:08:01 +00:00
Robert James Kaes
12fc92828c (malloc_shared_memory): Removed the MMAP_ANON and open("/dev/zero") since they are not portable across a while enough spectrum of machines. Right now tinyproxy is using a "classic" temporary file method of sharing memory. This will likely be improved in the future. 2002-05-29 20:51:35 +00:00
Robert James Kaes
360deb4568 Changed the tests on the return value from malloc_shared_memory() to make tinyproxy more portable, since we can't be certain that "if (!ret_value)" would actually detect a mmap() error. 2002-05-29 20:49:55 +00:00
Robert James Kaes
9b13e9bda8 (add_header_to_connection): Removed the "double_cgi" boolean, since tinyproxy now ignores all the headers after a "double CGI" situation has occurred. 
(get_all_headers): Instead of dropping duplicate headers when the "double CGI" situation occurs, tinyproxy will now drop _all_ the headers from the "inner" HTTP response.
 2002-05-29 18:11:57 +00:00
Robert James Kaes
5fcb8553da (init_stats): Fixed a spelling mistake where the number of bytes being allocated was incorrect. 2002-05-29 17:31:01 +00:00
Robert James Kaes
e7fcb5fc7d (add_header_to_connection): Added a boolean to indicate that a "Double CGI" situation is in affect. This is needed to solve a problem with some sites (like cgi.ebay.com) where they are sending two HTTP response lines (and associated headers) with a response. 
(get_all_headers): Detect if a "Double CGI" situation has occured.
 2002-05-28 20:40:01 +00:00
Robert James Kaes
cf2bd809fb (get_all_headers): Added code to ignore a "response" line in a header. This was pointed out as being a problem with eBay (cgi.ebay.com) 
(process_server_headers): Added code to make skip blank lines before a response line.
 2002-05-28 04:53:33 +00:00
Robert James Kaes
4ce9674365 (process_request): Changed the filtering code around to handle both domains and URLs. 2002-05-27 02:00:22 +00:00
Robert James Kaes
35d3d79e92 Added into the config structure the filter_urls and filter_extended flags. 2002-05-27 01:59:28 +00:00
Robert James Kaes
d64dfc5d77 Some spelling fixes. 2002-05-27 01:58:41 +00:00
Robert James Kaes
83a1a32f2a (opensock): Changed a comment around to better state what the code is actually doing. 2002-05-27 01:57:48 +00:00
Robert James Kaes
b11015c2e1 Added a copyright for James E. Flemer since these are his changes. 
(filter_init): Added code to handle both host and URLs.  Also include code to use extended regular expressions.
(filter_domain): The old filter_url function has been renamed filter_domain().
(filter_url): This function now actually filters complete URLs.
 2002-05-27 01:56:22 +00:00
Robert James Kaes
026c7d9a3d Added support for the "FilterURLs" and "FilterExtended" directives. 
These directives were submitted by James Flemer for use with the new
filtering code.
 2002-05-27 01:52:44 +00:00
Robert James Kaes
514182a05f (display_license): Updated the copyright dates 
(main): Moved the signals around so that the appropriate signal is assigned to either the children or just the parrent process.
Updated the copyright on the file.
 2002-05-27 00:46:24 +00:00
Robert James Kaes
9910c06bd2 Removed the "dnsserver" program all together, and changed the names of 
some of the files.
 2002-05-26 18:56:43 +00:00
Robert James Kaes
2e6ab58f37 Added the malloc_shared_memory() and calloc_shared_memory() function to 
allow the use of shared memory between all the children.
 2002-05-26 18:56:06 +00:00
Robert James Kaes
63f481c61a Spelling changes (from thread to child.) 2002-05-26 18:55:19 +00:00
Robert James Kaes
6cc0dce1b4 Removed the directives for the old DNSserver process. 2002-05-26 18:54:27 +00:00
Robert James Kaes
49b21c7e2f The stats structure has been moved into a shared memory block since it 
needs to be shared by all the children.
 2002-05-26 18:53:14 +00:00
Robert James Kaes
a67fb30bdf Removed all the code relating to the DNS API (dnsclient.h) as it's no 
longer needed with the new pre-forked model.
 2002-05-26 18:52:23 +00:00
Robert James Kaes
523f2003fa Removed the DNS API calls and replaced them with the standard 
gethostbyname() and gethostbyaddr() functions.  This is possible
because tinyproxy now uses a standard pre-forked() method.
 2002-05-26 18:51:17 +00:00
Robert James Kaes
71046cd407 Removed the "pthread" related includes. 2002-05-26 18:49:19 +00:00
Robert James Kaes
c35e56ae66 No longer using a threading model; so these files have been replaced by 
the child.c/child.h files (which use a pre-forked model.)
 2002-05-26 18:48:32 +00:00
Robert James Kaes
1fda8899b1 I didn't like the DNS co-process design so I changed tinyproxy from a 
threading model to a standard pre-forked model.  This means I don't need
the DNS co-process files.  Gone.
 2002-05-26 18:47:11 +00:00
Robert James Kaes
b3e657a00e Changed from using a threading model to a standard pre-forked model. 
Therefore the thread.c file has been removed and this file replaces it.
These files are really just the thread.c and thread.h files with all the
threading stuff replaced with fork() code.  Most of the code is identical.

a34db10d65 Fixed some spelling mistakes, and removed the getpeer_ip() and 
getpeer_string() functions as they've been replaced by the
getpeer_information() function.

b77fc5c860 Moved most of the function into separate files: the heap debugging 
functions are in "heap.c"; the daemon functions are in "daemon.c"; and,
the string/text functions are in "text.c".

16386fbb70 Added a new signal handler to handle SIGCHLD signals because of the new 
dnsserver child process.

Changed the set signal calls to use our new set_signal_handler() function.

Added code to start the "dnsserver" child process.

478030c6ff Changed the lookup_domain() function to use the new "dnsserver" API. 
Also moved safe_write(), safe_read(), readline(), and write_message()
functions into their own file.

47ab97a347 Fixed up a spelling mistake and changed various bits of code to take 
advantage of the fact that the peer's socket information is now stored
inside the connection structure.
 2002-05-23 18:24:46 +00:00
Robert James Kaes
1f9085cef2 Added the "DNSserverLocation" and "DNSserverSocket" directives for use 
with the "dnsserver" resolver.
 2002-05-23 18:24:02 +00:00
Robert James Kaes
09b1b9b925 Added the peer's socket information to the connection structure. The 
information is passed along during the initialization of the structure.
 2002-05-23 18:23:29 +00:00

9d0c65ad86 Fixed up the header includes for the new layout. 
Changed one line of code to make it explicit how the pointers are to be
updated.
 2002-05-23 18:22:48 +00:00

451fad1ed2 Changed the header includes around to reflect the new source layout. 2002-05-23 18:20:27 +00:00
Robert James Kaes
e633b97957 Added code to create the "dnsserver" program, and also reorganized to 
include the various new source files.
 2002-05-23 04:43:06 +00:00

1690c05075 Initial addition to CVS. Moved the three "text" related functions into a 
separate file.
 2002-05-23 04:42:30 +00:00

fd3e6e84fb Initial addition to CVS. Moved the network related functions into a 
separate module.
 2002-05-23 04:41:48 +00:00

c667952861 Initial addition to CVS. Moved all the debugging heap related functions. 2002-05-23 04:41:10 +00:00
Robert James Kaes
0b0e03fa39 Initial addition to CVS. The dnsserver process is a child executable that 
handle DNS resolving.
 2002-05-23 04:40:42 +00:00
Robert James Kaes
d22d6d181b Initial addition to CVS. These functions create an API for accessing the 
dnsserver child process.
 2002-05-23 04:40:06 +00:00
Robert James Kaes
2ee61db6af Initial addition into CVS. Moves various functions relating the daemon 
processes.  Added a portable signal handler setting function.
 2002-05-23 04:39:32 +00:00
Robert James Kaes
65cf5ea290 Initial addition to CVS. This header moves all the system includes from 
the tinyproxy.h file to here.

700f129750 Set the pointer to NULL after it's been freed() 2002-05-17 16:39:35 +00:00
Robert James Kaes
e4e78e0f1b request->host might have been freed by the time we get to 
free_request_struct(), so make sure it's pointing to memory.
 2002-05-17 16:34:42 +00:00
Robert James Kaes
bb9f206529 Moved the definition of the struct buffer_s into the buffer.c file and out 
of the buffer.h file.  This also required the removal of the BUFFER_SIZE
macro, and replace it with the buffer_size() function.
 2002-05-14 00:43:38 +00:00

d46cba8a0b Added a "tail" pointer to the vector to make insertions more efficient. 2002-05-13 23:32:16 +00:00
Robert James Kaes
16e96c79e8 Thanks to Justin Guyett for making the hashmap_insert() function use a 
constant time insert.  Explanation: new enteries are added to the _front_
of the chain, rather than search to the end.
 2002-05-13 20:02:23 +00:00
Robert James Kaes
73e3b495e0 Fixed up a potential SEGFAULT if memory for an entry could not be 
allocated.  Also, thanks to Justin Guyett for finding a problem the
hashmap_remove() function.  There was a problem where an entry's "prev"
pointer could be pointing to freed memory.

Finally, renamed all "maps" to bucket to make the source more
understandable.
 2002-05-13 18:47:46 +00:00

cf2ecb83b8 Removed the request logging in the tunnel because it breaks the tunnel 
concept since it blocks waiting for information from the client before any
data from the remote is relayed.
 2002-05-08 03:29:23 +00:00
Robert James Kaes
0a1f83bbe5 tinyproxy should be installed into the /sbin directory rather than the 
/bin directory since it's a network daemon.

3284f365b2 Check the return value of the write_message() function. 2002-04-28 20:03:53 +00:00
Robert James Kaes
ed90a4676f Added more error checking in process_client_headers() and 
process_server_headers() functions.

Also, better reporting of errors back to the client.
 2002-04-28 20:03:18 +00:00

f79807ac11 Added extra logging information, and made sure that locks were being 
released properly.

e4fe04cbaf Clear the total array of threads before any of the threads are created. 2002-04-28 03:09:52 +00:00
Robert James Kaes
577f3cebbf Fixed up the error detection code when relating the pthread functions. 
They return 0 if OK, and a positive error code.

Cleaned up the status setting code in thread_main().

Thanks to Hans-Georg Bork for fixing the problem in thread_pool_create()
where the status wasn't set early enough to allow all the threads to be
created.

Added additional logging information to let the admin know what is
happening with the thread creation.
 2002-04-28 02:37:01 +00:00

1a8c914dd2 Changed the len type to ssize_t because we need to detect errors in the 
recv() call.  Thanks to Tom Cross for discovering this bug.

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.
 2002-04-25 19:20:56 +00:00

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.
 2002-04-25 18:58:08 +00:00
Robert James Kaes
d1031e2c8f The hashmap API changed, so this function needs to be changed as well. 2002-04-25 18:56:43 +00:00
Robert James Kaes
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.
 2002-04-25 18:55:56 +00:00
Robert James Kaes
b5df4f1cf0 hashmap_search() only takes two arguments, so removed the unneeded NULL. 2002-04-25 18:52:09 +00:00
Robert James Kaes
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.)
 2002-04-24 16:48:34 +00:00
Robert James Kaes
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.
 2002-04-24 16:47:19 +00:00

89ada2df28 Moved bind_address inside the config structure. 2002-04-24 16:45:45 +00:00
Robert James Kaes
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.
 2002-04-22 19:41:17 +00:00

08077cc9e1 The "Bind" directive sets a binding address which the outgoing connections 
will use.
 2002-04-22 19:35:24 +00:00
Robert James Kaes
1953348c90 Added the "Proxy-Connection" header to the list of client headers which 
are not passed along.
 2002-04-22 19:34:50 +00:00
Robert James Kaes
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
Robert James Kaes
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
Robert James Kaes
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
Robert James Kaes
73a53daf38 Removed the call to hstrerror() in the getpeer_string() function. It's 
not available on all machines.
