2003-03-08 Robert James Kaes Released tinyproxy 1.5.3 (2003-03-10) Added the files required for creating tinyproxy RPMs for Redhat based systems. (See packaging/redhat) 2003-02-26 Robert James Kaes * src/tinyproxy.c (main): Removed duplicate code calling the filter_destroy() function. Once is enough. [Detected by John M Wright] 2003-01-27 Robert James Kaes * src/tinyproxy.c (display_usage): Removed the output line mentioning that regular expression support was included. It will be there always. * src/reqs.c (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. * doc/tinyproxy.conf, src/filter.c, src/grammar.y, src/scanner.l, * src/tinyproxy.h: Added support for conditionally using case sensitive filtering files. Code changes from James E. Flemer. * configure.ac: Moved the AH_TEMPLATE() macro for the GNU regex library to out from inside an if...fi test. Thanks to James E. Flemer for supplying a patch. Bumped up the version number. * doc/tinyproxy.8: Changed the default manual section to section 8 (administrator commands). * src/reqs.c (process_client_headers): Fixed inverted anonymous header logic. Fix comes from the FreeBSD port through James E. Flemer. 2003-01-22 Robert James Kaes Released tinyproxy 1.5.2 (2003-01-22) 2002-12-04 Robert James Kaes * src/reqs.c (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. * src/tinyproxy.c, src/tinyproxy.h, src/utils.c, src/utils.h, * src/common.h, src/conns.h, src/reqs.c: Removed the "bool_t" type since it conflicts with the newer C standards. The type was just replaced by "unsigned int" types. 2002-11-29 Robert James Kaes * src/reqs.c (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. 2002-11-26 Robert James Kaes * doc/tinyproxy.conf, src/grammar.y, src/reqs.c, src/scanner.l, * src/tinyproxy.h: Included code to disable the sending of the Via header. This is now controlled by the ViaHeader configure directive. 2002-11-21 Robert James Kaes * src/child.c (child_main): Cleaned up the notice string to be more clear why a child is being closed. * src/tinyproxy.c (main): Check to see if the PID file was created successfully, and if not report this to the user and close the program. * src/utils.c (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. 2002-11-13 Robert James Kaes * src/reqs.c (relay_connection): Shutdown the client socket for writing once all the data has been sent. * src/conns.c (destroy_conn): Added code to log any error messages when the sockets are closed. 2002-11-05 Robert James Kaes * doc/tinyproxy.conf: Removed the example for the Tunnel directive since it's been removed. 2002-11-03 Robert James Kaes * configure.ac, src/grammar.y, src/reqs.c, src/scanner.l, src/tinyproxy.c, src/tinyproxy.h: 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. 2002-10-17 Robert James Kaes * src/reqs.c (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. 2002-10-03 Robert James Kaes * src/tinyproxy.c: 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. * src/log.c, src/log.h: 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. * src/filter.c: Filtering is now case insensitive. * src/child.c (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. 2002-08-09 Robert James Kaes Released tinyproxy 1.5.1 (2002-08-09) 2002-07-09 Robert James Kaes * src/utils.c: (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. * src/heap.c (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. 2002-07-08 Robert James Kaes * README: Updated the "Support" section to include a link to the tinyproxy Bug Tracker system hosted by SourceForge. 2002-07-05 Robert James Kaes * configure.ac: Removed the -D_REENTRANT C flag since tinyproxy is no longer a multi-threaded program. 2002-06-27 Robert James Kaes * src/child.c (child_make): Reset the various signals to the default signal handler so that the children can be properly destroyed. 2002-06-15 Robert James Kaes * src/log.c (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. * src/tinyproxy.c: 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. * src/child.c (child_main_loop): Moved the filter re-initiation code into the loop. This code is activated whenever the SIGHUP signal is received. * src/tinyproxy.h: Removed the "logf" FILE structure from the config structure, and also renamed the "log_rotation_request" boolean to "received_sighup". * src/utils.c, src/utils.h: 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. 2002-06-07 Robert James Kaes * src/filter.c, src/filter.h: 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. * doc/tinyproxy.conf, src/grammar.y, src/scanner.l: 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. 2002-06-06 Robert James Kaes * src/reqs.c: 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 * src/filter.c (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. * src/tinyproxy.c (display_usage): Added a message indicating whether transparent proxy support has been compiled in. * configure.ac: Added the "--enable-transparent-proxy" flag and moved the AH_TEMPLATE() macros to _outside_ the "if" tests. * src/grammar.y: Added a warning message to the Bind directive stating that it will be ignored if "transparent proxy" has been compiled into tinyproxy. * src/log.c (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. 2002-06-05 Robert James Kaes * doc/Makefile.am: Added the "filter-howto.txt" file to the distribution. * doc/filter-howto.txt: Added a short filtering HOWTO document from Patrick L. McGillan. * src/child.c (child_main): Added a DEBUG call to let me know which process has accepted a connection. This is needed for debugging using "gdb". * src/heap.c (malloc_shared_memory): Removed the assert() call for shared_file since it's now a static variable. * src/acl.c (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. 2002-05-31 Robert James Kaes * src/utils.c (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. * src/tinyproxy.c: The log file is now opened in "append" mode so that you can restart tinyproxy without losing the log file. * src/reqs.c (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. * src/sock.c (getpeer_information): Fixed a problem retrieving the FQDN of a host because I was passing in an incorrect parameter to gethostbyaddr(). D'oh. 2002-05-29 Robert James Kaes * src/heap.c (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. * src/child.c, src/stats.c: 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. * src/reqs.c (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. * src/stats.c (init_stats): Fixed a spelling mistake where the number of bytes being allocated was incorrect. 2002-05-28 Robert James Kaes * src/reqs.c (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 occurred. * src/reqs.c (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. 2002-05-27 Robert James Kaes * doc/Makefile.am: Fixed up a problem where the tinyproxy manual page was not getting included with the distribution. * src/reqs.c (process_request): Changed the filtering code around to handle both domains and URLs. * src/tinyproxy.h: Added into the config structure the filter_urls and filter_extended flags. * src/tinyproxy.c: Some spelling fixes. * src/sock.c (opensock): Changed a comment around to better state what the code is actually doing. * src/filter.c, src/filter.h: 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. * doc/tinyproxy.conf, src/grammar.y, src/scanner.l: Added support for the "FilterURLs" and "FilterExtended" directives. These directives were submitted by James Flemer for use with the new filtering code. * configure.ac: Updated the version number (pre 1) * src/tinyproxy.c (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. 2002-05-26 Robert James Kaes * doc/tinyproxy.conf: Removed the "DNSserver" directives since they're no longer needed. * configure.ac: Removed the pthread related tests and added a test for the sys/mman.h header (needed for shared memory.) * src/Makefile.am: Removed the "dnsserver" program all together, and changed the names of some of the files. * src/heap.c, src/heap.h: Added the malloc_shared_memory() and calloc_shared_memory() function to allow the use of shared memory between all the children. * src/log.h, src/reqs.c: Spelling changes (from thread to child.) * src/grammar.y, src/scanner.l: Removed the directives for the old DNSserver process. * src/stats.c: The stats structure has been moved into a shared memory block since it needs to be shared by all the children. * src/tinyproxy.c: Removed all the code relating to the DNS API as it's no longer needed with the new pre-forked model. Updated the copyright dates. (main): Moved the signals around so that they are assigned to the appropriate process level: either the parent only, or all processes. * src/sock.c: 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. * src/common.h: Removed the "pthread" related includes. * src/thread.c, src/thread.h: 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. * src/dnsclient.h, src/dnsserver.c, src/dnsclient.c: 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. * src/child.c, src/child.h: 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. 2002-05-24 Robert James Kaes * src/buffer.c, src/conns.c, src/dnsclient.c, src/hashmap.c, src/reqs.c, src/stats.c, src/text.c, src/thread.c, src/tinyproxy.c, src/utils.c, src/vector.c: Fixed a tonne of spelling mistakes. * src/sock.c: Fixed some spelling mistakes, and removed the getpeer_ip() and getpeer_string() functions as they've been replaced by the getpeer_information() function. 2002-05-23 Robert James Kaes * src/dnsserver.c: The DNS resolver for use by the various tinyproxy threads. The DNS resolver was moved into a separate function to prevent the blocking problem the 1.4.x and 1.5.0 versions experienced when a DNS query would take a long time to return. While the query was blocking, other threads could not establish their own queries, so they all blocked. Not so good. * src/dnsclient.c: Introduce the new "dnsserver" API. These functions are the client side access points. * src/utils.c: Moved most of the code into separate files. The debugging heap related code is now in heap.c; the text string code is in text.c; and, the daemon related code is in daemon.c. * src/tinyproxy.h: Moved all the system header include code into the "common.h" file. * src/tinyproxy.c (takesig): Added a signal handler for the SIGCHLD signals since a child process is spawned to handle the "dnsserver" process. (main): Added code to start and stop the "dnsserver" process. Switched the signal setup function to the new portable set_signal_handler() function. Include a test to make sure the two "dnsserver" directives are set. * src/sock.c (lookup_domain): Rewrote the function to use the new "dnsserver" API. This removes the need for the pthread mutex. (getpeer_information): Replaced the two calls to getpeer_ip() and getpeer_string() with one call to this function. Streamlines the peer information retrieval. Moved the safe_write(), safe_read(), readline(), write_message() functions into a separate file: network.c * src/reqs.c (process_request): Fixed a spelling mistake. (add_xtinyproxy_header): The peer information is stored in the connection, so removed the call to query it again. (handle_connection): Pass the peer socket's information into the connection structure for later use. * src/grammar.y: * src/scanner.l: Added the "DNSserverLocation" and "DNSserverSocket" directives as they are required to properly run the "dnsserver" DNS resolver. * src/conns.c (initialize_conn): Added the peer's IP dotted-decimal address and hostname to the connection structure. It's faster to get the information _once_ and just store it for later use. * src/buffer.c (add_to_buffer): Changed the code to make the order of insertion into the linked list explicit. I'm not sure if this fixes a bug or not, but clarity is alway nice. 2002-05-13 Robert James Kaes * src/buffer.h: Moved the definition of the buffer_s structure. Data hiding is a good thing. Also, replaced the BUFFER_SIZE macro with a buffer_size() function. * src/vector.c: Added the "tail" pointer to make insertions more efficient. * src/hashmap.c (hashmap_insert): Fixed a potential SEGFAULT if the memory for the new hashmap entry could not be allocated. (hashmap_remove): Fixed a problem where an entry could have it's "prev" pointer still pointing at freed memory. Thanks to Justin Guyett for finding and fixing this problem. (hashmap_insert): Thanks to Justin Guyett for changing the code to use a constant time insert. Much cleaner _and_ faster. 2002-05-10 Robert James Kaes * Makefile.am (install-data-local): Fixed up the tinyproxy.conf test so that the file is only installed if it doesn't already exist. 2002-05-09 Robert James Kaes Released tinyproxy 1.5.0 (2002-05-09) 2002-05-08 Robert James Kaes * configure.ac: The --with-config option now supports absolute paths. If an absolute path is given, the full directory path and file name are extracted into their appropriate parts. 2002-05-07 Robert James Kaes * src/reqs.c (connect_to_tunnel): Removed request logging code in the tunnel method since it breaks the "tunnel" concept. 2002-05-02 Robert James Kaes * configure.ac: Added code to figure out exactly where to install the configuration file. * Makefile.am (install-data-local): Added a new install run to install the configuration file to the location specified in DEFAULT_CONF_FILE. 2002-04-28 Robert James Kaes * src/reqs.c (process_client_headers): (process_server_headers): Added more error checking code and send HTTP errors back to the client to let them know what is happening. (handle_connection): If there was a server error when processing the headers, send an error back to the client. 2002-04-27 Robert James Kaes * src/thread.c (thread_pool_create): Set the thread's status _before_ the thread is created. Thanks to Hans-Georg Bork for solving this problem. (thread_main): Fixed up the status setting code. Removed duplicated code and explicitly set the status when needed. Fixed up all the code checking the return value from the pthread functions. These functions return 0 if OK, but a _positive_ error code. 2002-04-26 Robert James Kaes * src/thread.c: servers_waiting needs to be signed, since it can go below 0 without causing a problem, but if it wraps around all hell can break loose. * src/reqs.c (connect_to_tunnel): Changed the len type to an signed integer so that we can detect error conditions. Thanks to Tom Cross for pointing out this problem. * src/log.c (send_stored_logs): Check the return value of hashmap_first() since it could be -1, indicating an empty hashmap. * src/reqs.c (process_client_headers): (process_server_headers): Test the return value of hashmap_first() since the hashmap could be empty (returning a -1 via hashmap_first.) 2002-04-25 Robert James Kaes * src/reqs.c (remove_connection_headers): Handle both the Connection header _and_ the Proxy-Connection header. (free_request_struct): Check to see if request->path is actually allocated before trying to delete it. * src/hashmap.c: The hashmap will now handle multiple keys with the same value. This change was need because some sites like Yahoo will send out multiple "Set-Cookie" lines. The hashmap_keys() function has been removed and has been replaced with the iterator concept. Also, a few of the functions have had either their arguments changed, or their return type. Read the comments in the header file for more information. 2002-04-22 Robert James Kaes * src/thread.c: Renamed the LOCKing macros and added debugging asserts to them. Also, moved the mutex initialization into the thread_pool_create() function since I would like to use an error checking mutex, but my machine doesn't seem to work with it. I left the code there in case I can get it to work later. * src/log.c (send_stored_logs): Added this function since the log_message() function will now stored the messages if the config file has not been processed yet. This function is called from within main() to output the messages to the log file _after_ it's been initialized. * src/reqs.c (process_client_headers): Added the "Proxy-Connection" header to the list of client headers we don't forward to the remote machine. Added the the "Bind" directive. This is used to indicate which IP address in a multi-homed machine you would like tinyproxy to bind out-going connections to. This complements the "Listen" directive for incoming connections. 2002-04-18 Robert James Kaes * src/sock.c (lookup_domain): Removed the call to inet_aton() since the gethostbyname() will handle the dotted-decimal case anyway. * src/reqs.c: Added a new show_stats field in the conn_s structure so that we will process the client's headers properly before trying to send a HTTP response back. * src/sock.c (getpeer_string): Removed the hstrerror() call since it's not supported on all machines, and it's not really needed anyway. * src/vector.c: * src/hashmap.c: Changed all calls to malloc, calloc, free, and strdup to the appropriate safe variety. (hashmap_delete): Fixed a memory leak where the maps were not being freed properly. * src/utils.c (debugging_strdup): Added this function to be used by the safestrdup() macro to replace all the calls to strdup(). This should allow better tracking of the memory usage. Also, all the debugging_* functions have had asserts added to them to hopefully improve the quality of the code. * src/reqs.c (get_all_headers): Fixed a memory leak since I was not freeing the header variable, even though the hashmap makes a copy of it. Thanks to Petr Lampa for finding this one. * src/tinyproxy.c (takesig): Moved the filter_destroy() code out of the signal handler and placed it inside of main(). Same reasoning as the rotate_log_files() changes below. * src/utils.c (rotate_log_files): Moved the log rotation code out of the signal handler and into it's own function. Also improved the robustness of the code. Credit to Petr Lampa for suggesting that system calls in a signal handler is bad magic. Now the signal handler sets a flag which is responded to inside of thread_main_loop(). 2002-04-17 Robert James Kaes * configure.ac: Added test for pthread_cancel() since it doesn't seem to be available on every platform, even if the rest of pthread is. Thanks to Daniel Flemming and Petr Lampa for reporting this problem. * src/sock.c (lookup_domain): Removed the LOOKUP_LOCK() and LOOKUP_UNLOCK() macros and replaced them with calls the LOCK() and UNLOCK(). The reason for this change is that I can not be sure that calls to gethostbyname() and gethostbyaddr() will not over-write the same static block of memory. Potential problem pointed out by Petr Lampa. * src/reqs.c (handle_connection): If the initialize_conn() function fails, we need to close the socket. * src/acl.c (check_acl): Changed the code to accept the peer IP address and string address from the calling function (in this case handle_connection.) * src/thread.c (thread_main): Removed close(connfd) since it has already been closed from within handle_connection(). Thanks to Petr Lampa for spotting this. (thread_pool_create): Added test to make sure pthread_create() succeeds, and returns -1 if all the threads could not be created. (thread_main_loop): Added test to determine if the pthread_create() call succeeded. Warns the admin if there was a problem, but tinyproxy will continue to run. 2002-04-15 Robert James Kaes * src/anonymous.c (anonymous_insert): Now returns -1 upon error, and 0 upon success. This simplified the code, since I don't care whether the success is from a successful insert, or because the string was already present in the hashmap. (anonymous_search): The function now returns a positive number greater than zero if the string was found, otherwise zero or a negative value is returned. Needed to change the _one_ call to this function to use the new return method. * src/reqs.c (pull_client_data): Moved the common error exit together. Better, smaller code is produced. (add_header_to_connection): Changed the code a bit to remove the call to strlen() and the variable associated with it. (establish_http_connection): Changed the three calls to write_message() and safe_write() into one combined call to write_message(). (send_ssl_response): Replaced the three calls to safe_write() into one call to write_message(). (extract_http_url): Moved the common error code into it's own section and jump to it upon error. 2002-04-14 Robert James Kaes * src/utils.c (chomp): Added an assert to detect a design error. * src/reqs.c (read_request_line): Fixed the return type to be an signed variable, so that we preserve a negative return value upon an error. * src/sock.c (readline): Added a test for allocating enough memory for the whole_buffer. * src/conns.h: Replaced the error boolean with a pointer to an error string and error number for use in the send_http_error_message() function. * src/utils.c (indicate_http_error): Replaced the httperr() function with this one. Instead of sending the error right away, we store the error string and number and send them _after_ the client headers have been processed. 2002-04-13 Robert James Kaes * src/sock.c (opensock): If the Listen directive is in use, then we should bind outgoing address to this address. (listen_sock): Added error handling for the bind() and listen() calls when setting up the listening socket. 2002-04-12 Robert James Kaes * src/scanner.l: * src/grammar.y: Added code for the ConnectPort directive. * src/reqs.c (add_connect_port_allowed): (check_allowed_connect_ports): Added these two functions (breaking by no new features rule) because they fix a security problem with tinyproxy. These functions are needed to support the ConnectPort configuration directives, which allows the admin to specify which ports are allowed by a CONNECT method. This is needed to prevent people from using tinyproxy to connect to mail servers (port 25) to do "bad things." 2002-04-11 Robert James Kaes * src/reqs.c (remove_connection_headers): Moved all the code for detecting and removing headers based on the Connection header into this function. (get_content_length): Moved the check for a Content-Length value into it's own function. (process_client_headers): Changed the code to use the newer remove_connection_headers() and get_content_length() functions. (process_server_headers): Rewrote this function to handle the headers in a more consistent manner. The connection header is handled correctly, and the content-length header is stored for later use. Also, include a list of headers to not send. (relay_connection): Added a test to use the connptr->remote_content_length value if it's present. (write_via_header): Moved the creation/modification of the Via header into it's own function since it's used by both process_client_headers() and process_server_headers(). I still need to add code to allow you to "hide" the host information if you so choose. * src/conns.c: Added the remote_content_length variable to hold the number of bytes the remove server is _supposed_ to send to us. This fixes a problem where the remote server doesn't close the connection after sending the body. Problem was reported by James Flemer. 2002-04-10 Robert James Kaes * src/Makefile.am: Removed the dependency on LIBOBJS and instead replaced it with an ADDITIONAL_OBJECTS variable defined within the configure script. This allows greater control over what is compiled. * configure.ac: Removed the AC_FUNC_LSTAT macro since it wants to add lstat.o onto some machines. I don't think the test was really needed anyway, so it's better to have it gone. 2002-04-09 Robert James Kaes * src/anonymous.c: Changed this module to use the hashmap module instead of it's own internal linked list. Common code is good. :) * src/reqs.c (process_client_headers): Fixed the XTINYPROXY_ENABLE section to actually check if xtinyproxy has been configured. (compare_headers): Removed this function since it's been replaced by a call to anonymous_search(). * src/acl.c (make_netmask): James Flemer cleaned up the make_netmask() function to remove the big static table. Much nicer now. * configure.ac: The configure script now doesn't include a check for the malloc.h header if tinyproxy is being compiled on an OpenBSD machine. I might actually just remove the malloc.h header since the malloc/calloc/realloc/free functions are supposed to be in the stdlib.h header. I also changed the LIBOBJS="" lines to AC_LIBOBJ() macro so conform to the new Autoconf rules. * src/hashmap.c: * src/vector.c: Cleaned up the include headers to _hopefully_ be more portable. Who knows though. 2002-04-08 Robert James Kaes * src/thread.c (thread_main_loop): Moved the looping code into this function from the main() function. Just a bit of clean up. (thread_main): Changed the default cancellation point to asynchronous, which means immediately. This should fix up the problem where the threads would not free correctly. 2002-04-07 Robert James Kaes * src/hashmap.c: * src/vector.c: These two "modules" are used within the reqs.c file to better handle the headers from the clients. * src/reqs.c: Tonnes of functions changed. The most significant is the process_client_header() function which is now using the hashmap functions to handle the Connection header more accurately. With the addition of the add_header_to_connection(), get_all_headers(), and remove_connection_headers() function, the compare_header() function is _vastly_ simplified. Just read the comments in the source itself for more information. * src/conns.c: Cleaned up the initialize_conn and destroy_conn functions to better handle error conditions. 2002-04-02 Robert James Kaes * configure.ac: Patch from James Flamer which fixes a problem with the --disable-* options and also prevents -lc_r from being included on FreeBSD machines. 2002-01-13 Robert James Kaes * src/thread.c (thread_kill_threads): Added a function to explicitly go through all the active threads and kill them. 2002-01-07 Robert James Kaes * src/thread.c (thread_main): Added code to check if tinyproxy is being killed by the user. 2001-12-28 Robert James Kaes * src/thread.c (thread_main): Added code to detect errors in the accept() function. 2001-12-23 Robert James Kaes * src/utils.c (send_http_message): Use the write_message() function for creating and sending the headers to the client. (httperr): Use similar code to write_message() to create the body of the error message. I use this so that there is no limit to the size of the error message (better coding. :) I'm still trying to figure out how to combine this code with write_message() into a common function. * src/sock.c (write_message): Moved write_message() into sock.c since it's now accessed by more than just the reqs.c file. * src/tinyproxy.c (main): Made the error log for the idle time setting more verbose so that it's explains the reasoning better. Also, changed the level to WARNING. * src/reqs.c (process_client_headers): Cleaned up the code to send the Via header by using the write_message() function. 2001-12-22 Robert James Kaes * src/tinyproxy.h: Add a test for the MSG_NOSIGNAL define, so it's apparently a non-standard extension to send(). Also, moved the include after the includes for the various time include files. 2001-12-19 Robert James Kaes * src/reqs.c (write_message): Encapsulate code to handle sending snprintf() built lines to a file descriptor. (process_server_headers): Removed duplicate code and used the return value from readline() instead of recalculating it by strlen(). 2001-12-18 Robert James Kaes * src/reqs.c (connect_to_tunnel): Moved the tunnel connection code into its own function. (TUNNEL_CONFIGURED): Added a macro to help simplify the tests for tunneling support. 2001-12-17 Robert James Kaes * src/reqs.c (handle_connection): Also log the request when tinyproxy is in tunneling mode. This was implemented by Hans-Georg Bork. 2001-12-16 Robert James Kaes * src/sock.c (safe_write): Add assert() calls to make sure the arguments are sane. * src/reqs.c (read_request_line): Ignore any blank lines if tinyproxy is expecting a request line. This is suggested by RFC2616 for a tolerant application. (UPSTREAM_CONFIGURED): Added a macro to encapsulate the test for upstream proxy support. (establish_http_connection): Lines are now composed in a buffer and then sent to the safe_write() function. This was done because some sites (like www.heise.de) do not like having the request line sent in pieces. 2001-12-15 Robert James Kaes * src/sock.c (safe_write): In addition to handling "interruption" errors, continue sending the buffer until it has been fully sent or a fatal error occurred. * src/anonymous.c: Removed the calls to the ternary tree and just use a basic linked list. The ternary tree might have been slightly faster, but since tinyproxy is only dealing with a "few" anonymous headers the ternary tree code was _way_ overkill. * src/sock.c (lookup_domain): Removed the DNS cache since according to RFC2616 a HTTP client should not cache an address if the client doesn't also respect the TTL value. tinyproxy does not have a complete DNS resolver. Additionally, a caching DNS system is an administrator decision which should not be included in tinyproxy. 2001-11-25 Robert James Kaes * src/buffer.c (makenewline): This function now copies the actual data itself. This means any malloc() and free() functions are closer together, instead of malloc()ing the data and then not free()ing it. (add_to_buffer): Add a new "line" to the buffer. I'm trying to have more of the data go through the buffering code. Basically the safe_write() function should only be called when the data needs to be sent _now_. (read_buffer): Fixed the code so that buffering _actually_ happens. :) The code will now buffer up to MAXBUFFSIZE bytes (which is currently 48 KB.) 2001-11-24 Robert James Kaes * configure.ac: Changed the extension of the configure.in to match the new standard for the autoconf program. Also, replaced all the obsolete macros with the new standard. autoconf 2.52 is now the minimum required to process this file. 2001-11-23 Robert James Kaes * src/sock.c (readline): Limit the maximum size of the buffer so that we don't create a situation where tinyproxy could use all the memory in a system. Right now we're limiting a line to a maximum of 128KB. 2001-11-21 Robert James Kaes Released tinyproxy 1.4.3 (2001-11-21) * src/utils.c (chomp): Replaced the "trim()" function in reqs.c with the new chomp() function which has similar semantics as the chomp() function in Perl. * src/sock.c (readline): Replaced the old function with a new version that will allow an arbitrary long string. 2001-11-03 Robert James Kaes * src/buffer.c (remove_from_buffer): This function is never called with an empty buffer, so removed some inaccurate code which would have removed an invalid line from the buffer if it was empty. What was I thinking when I wrote that? Good thing is was never called. (add_to_buffer): Add a bit of a sanity check to make sure the buffer structure hasn't been messed up some how. 2001-11-02 Robert James Kaes * src/acl.c (insert_acl): Tightened the check regarding whether an ACL is a string or a numeric address. 2001-10-25 Robert James Kaes * Moved all the system header included into the tinyproxy.h header and changed all the other files to include it. This should centralize the header dependency issue into one file. * src/conns.c: Brought back the conns.{c,h} files which contain the connection structure definition plus the creation/destruction routines. * src/reqs.c (process_client_headers): Selectively send headers based on whether we're using an upstream with a CONNECT request. The short answer: all methods work correctly with Upstream proxying and normal proxying. * src/tinyproxy.h: Added a upstream flag to the conn_s structure so we can figure out when to send headers and when not to send headers. This is extremely important when trying to do upstream proxying of the CONNECT method. * src/reqs.c (relay_connection): Empty the contents of both buffers when either socket is closed. This is more in line with what a tunnel should do. Since either end could close with information still in the buffers. (connect_to_upstream): Cleaned up the code to re-use the establish_http_connection() function. * src/buffer.c (readbuff): Changed the memory allocation to 2K from 48K since an Ethernet connection is usually around 1400 bytes. There's little point in allocating a huge amount of memory, only to shrink the memory map in the next breath. 2001-10-22 Robert James Kaes * src/sock.c (getpeer_string): Added logging in case the gethostbyaddr() function fails. * src/reqs.c (free_request_struct): Added a test to return if the pointer is NULL. (handle_connection): Cleaned up the code to better handle the cause where the request is NULL. * src/sock.c (getpeer_string): * src/sock.c (getpeer_ip): When the DNS lookup fails, we need to initialized the user's buffer to an empty string; otherwise, the user's buffer will contain garbage and cause a SEGFAULT. Thanks to Jeffrey Wheelhouse for finding this bug. 2001-10-18 Robert James Kaes * src/reqs.c (connect_to_upstream): Moved the code needed to rebuild the request line when using the upstream feature into it's own function. Simplifies the handle_connection() function. * src/buffer.c (readbuff): Fixed a problem where a full buffer would cause the connection to be closed. Thanks to Jeffrey Wheelhouse for helping me find this problem. 2001-09-29 Robert James Kaes * configure.in: Uses any CFLAGS variable passed to the configure script. Also, '-g -Wall' is _not_ enabled unless debugging support is compiled in. Use --enable-static to compile a statically linked tinyproxy. 2001-09-16 Robert James Kaes * src/tinyproxy.c (main): Don't allow Tunnel and Upstream directives to be both set in the configuration file. * src/reqs.c (handle_connection): Added support for an upstream proxy. What we used to use for our upstream proxy has now become a TCP tunnel. The difference is that the upstream proxy will do domain filtering, anonymous headers, etc. while the TCP tunnel just sends the data without any processing. You can not have both at the same time. * src/utils.c (send_http_message): Instead of creating a block of memory with the output message, just send it to the client. We still need to process the various headers from the client, but it will pick up the error when it's done talking to the proxy. Uses less memory. * src/sock.c: Moved safe_write() and safe_read() into sock.c since I'm using them in more than just reqs.c. 2001-09-15 Robert James Kaes * Removed all the log_message()s which reported that memory could not be allocated. There's little point in reporting a memory shortage since the computer will probably crash soon anyway. * src/reqs.c (process_request): Added the code for showing the stats back into the function. * src/tinyproxy.c (takesig): When SIGHUP is received the log file is rotated instead of being truncated. The rotated log has ".rot" appended to the file name. 2001-09-14 Robert James Kaes * src/uri.c: Removed this file since it's no longer needed. * src/reqs.c: Split the process_method() function into separate smaller functions. Added support for tunnel SSL connections. * src/tinyproxy.h: Added a field to handle SSL connections. 2001-09-11 Robert James Kaes * src/reqs.c (process_method): Fixed a memory leak due to the change to heap allocation if there is an error. * src/utils.c (debugging_realloc): Added the debugging version of realloc(). * src/thread.c (THREAD_STACK_SIZE): Changed a threads stack size to 32KB from 128KB. * src/reqs.c (process_method): * src/reqs.c (pull_client_data): * src/reqs.c (process_client_headers): * src/reqs.c (process_server_headers): * src/buffer.c (readbuff): Using heap allocated memory for the buffer rather than stack memory. * src/uri.c (explode_uri): Fixed a potential memory leak where the regular expression structure might not be freed if there was an error in the expression. 2001-09-08 Robert James Kaes * src/ternary.c (BUFARRAY & BUFSIZE): Lowered the values to help lower memory usage. A ternary tree will now max out at 4MB. * src/utils.c: Added debugging_(malloc|calloc|free) to help track down memory leaks. * src/dnscache.c (DNS_INSERT_LIMIT): Lower the number of insertions before the ternary tree is rebuilt. * src/thread.c (thread_main): Fixed a memory leak. 2001-09-07 Robert James Kaes * src/thread.c (thread_pool_create): Explicitly set the detach state for threads to PTHREAD_CREATE_DETACHED. * Various error message clean up. * src/thread.c (thread_main): Add locking around the servers_waiting thread. 2001-09-06 Robert James Kaes * src/thread.c (thread_main): The code which closes a thread doesn't actually work correct so I've moved the test to just after a thread has handled a connection. The code still needs to be cleaned up to handle locking. * src/ternary.c (ternary_destroy): Fixed the deletion code as it would cause a segfault if it was every called. Also, lowered the sizes of the arrays for better memory usage. * src/dnscache.c: After a certain number of insertions delete the DNS cache and free the memory. The reason for this is that a ternary tree doesn't lend itself to removing individual entries. It's just easier (and cleaner) to simply delete the cache. 2001-09-04 Robert James Kaes Released tinyproxy 1.4.2.2 (2001-09-04) * src/reqs.c (process_client_headers): Moved the skip header test in front of the compare_header() function. * src/ternary.c (ternary_search): Switched to doing case insensitive searching. * src/log.c (log_message): Thanks to NeilK for finding and fixing a problem with the syslog code which can lead to a format string attack. 2001-08-30 Robert James Kaes * src/dnscache.c: Removed the insert_data() function and replaced the "replace" logic in dns_insert() with a call to ternary_replace(). This fixes the segmentation fault problem which I introduced when I "tried" to fix the memory leak. Also changed the LOCKing to be around the entire dnscache() again since I still need to work out how locking should be done when accessing the ternary tree. * src/ternary.c (ternary_insert_replace): Renamed ternary_insert() to ternary_insert_replace() and added a extra argument. The function can now "replace" data already in the tree without causing a memory leak. Added two DEFINES to make coding easier: ternary_insert() and ternary_replace() which both call this function with the right arguments. * src/utils.c: Removed xstrstr() since it was only used in one place, and could be safely replaced with strstr. I can't even remember why we had this function to begin with. * src/reqs.c (compare_header): Removed the call to xstrstr() since it's been removed from the source. 2001-08-29 Robert James Kaes Released tinyproxy 1.4.2 (2001-08-29) 2001-08-28 Robert James Kaes Released tinyproxy 1.4.1.5 (2001-08-28) * src/log.c (log_message): Handle a debug enabled compile better. * src/dnscache.c (dns_insert): Fixed a memory leak if the same information was inserted into the ternary tree twice. * configure.in: Fixed the test regarding the REGEX library. Even if a working REGEX was found on the system, the included REGEX was being compiled in. Double Doh. * src/log.c (log_message): Finally got the log levels worked out properly. I've tested all the levels and they now produce the correct output. 2001-08-27 Robert James Kaes Released tinyproxy 1.4.1.4 (2001-08-27) * src/reqs.c (trim): Moved the trim functionality out of process_request() and added a test to make sure we don't back the pointer past the beginning of the string. * src/log.c (log_message): Fixed a problem where the connect messages were not getting through if the log level was set to INFO. * src/tinyproxy.h: Moved some of the includes around so that tinyproxy can compile correctly on FreeBSD systems. * src/thread.c: Added the pthread_attr_t structure since we're going to be using a non-default sized stack because some OS's have a stack size which is too small. * configure.in: Added a test for detecting FreeBSD's -pthread mechanism for telling GCC to use POSIX threading. * src/utils.c (httperr): Fixed the MIME type. Should be be text/html, not text/mime. Fix one bug, add two new ones. Sigh. 2001-08-26 Robert James Kaes Released tinyproxy 1.4.1.3 (2001-08-26) Released tinyproxy 1.4.1 (2001-08-26) * src/utils.c (httperr): Split the headers from the actual message and include more headers like Date, Server, Content-Length, etc. Also set the type for the error message to const char*. * src/reqs.c (process_method): Fixed a SEGV problem if an invalid request was submitted. * Makefile.am (EXTRA_DIST): Don't include ./reconf in the tarball. * src/log.c (log_message): Fixed a problem with the new LOG_CONN log level. * configure.in: The debugging code was being included even on non-debugging builds. * src/anonymous.c (anonymous_insert): Moved the creation of the search tree into the anonymous_insert() function. Therefore, the search tree is _not_ created until the first insertion. This should also fix a bug in main() where I was inserting headers before creating the search tree. Doh. (is_anonymous_enabled): Removed the tests for config.anon and replaced it with a function call which returns a BOOL. * Spell checked the ChangeLog file! :) 2001-08-25 Robert James Kaes * src/thread.c (thread_main): Thanks to Hans-Georg Bork for fixing a problem where the status of the threads was not going back to T_WAITING if MaxRequestsPerChild was 0. Also, fixed a problem with the looping system where the Debian start-stop-daemon script would not stop all the threads if new threads had been created. * src/log.h (LOG_CONN): Added the LOG_CONN log level. This is less verbose than LOG_INFO. * doc/tinyproxy.8: Added the -l option to the list of command line options. * src/anonymous.c (anon_insert): Fixed a bug where anonymous filtering wasn't working even if it was specified in the configuration file. 2001-07-02 Robert James Kaes * src/tinyproxy.c (versiondisp): Added George Talusan to the copyright message. Also now include the target system name to the version message. 2001-06-24 Robert James Kaes Released tinyproxy 1.4.0 (2001-06-24) 2001-06-06 Robert James Kaes * configure.in: Total reorganization. 2001-06-04 Robert James Kaes * configure.in: Remove the --with-* for port, logfile, and user since the configuration file handles this now. Fixed a problem where we were testing for the libraries correctly, but not actually including them in the linking. 2001-06-02 Robert James Kaes * doc/tinyproxy.conf: Clarified the LogLevel directive. * configure.in: Fixed up the tests for libsocket, libnsl, and libresolv. Also improved the test for the yacc program since I used bison 1.25 to originally write it. Updated the list of headers to look for when configuring. Bumped up the version. 2001-06-01 Robert James Kaes * configure.in: Fixed a problem when using the --with-port= config * src/tinyproxy.c (main): Change the logging level from LOG_EMERG (which doesn't exist anymore) to LOG_CRIT. * src/scanner.l: Added the strings in the data structure to handle the LogLevel switch. * src/log.c (set_log_level): Code for handling selective logging. * src/grammar.y: Added the tokens and code for handling the LogLevel switch in the configuration file. * configure.in: Added a test for the resolv library for the gethostby* functions. Also bumped up the pre-version. 2001-05-26 Robert James Kaes * src/tinyproxy.c (main): Added code to stop the creation of core files. * src/reqs.c (process_method): Fixed a memory leak. (relay_connection): Cleaned up the code to remove some unneeded variables and removed redundant code. * src/log.c (log_message): Renamed "log()" function to log_message(). * src/dnscache.c (new_dnscache): * src/anonymous.c (new_anonymous): Fixed the return type. 2001-03-26 00:00 rjkaes Released tinyproxy 1.3.3b (2001-03-26) 2001-01-17 00:00 rjkaes Released tinyproxy 1.3.3a (2001-01-17) 2001-01-15 12:13 rjkaes * configure.in: Bumped up the pre version number 2001-01-15 12:11 rjkaes * ChangeLog, src/reqs.c, src/stats.c: Fixed more potential overflow bugs. 2001-01-15 12:06 rjkaes * ChangeLog, src/utils.c: Fixed a potential security bug in http_err. There was a possibility of a heap overflow exploit. 2001-01-02 14:30 rjkaes * src/scanner.l: Fixed a bug where the ':' character was not being properly detected. 2000-12-09 15:03 rjkaes * configure.in: Rolling out the first pre to 1.4.0 2000-12-08 21:35 rjkaes * src/thread.c: Implemented the MaxRequestsPerChild directive. 2000-12-07 22:35 rjkaes * ChangeLog: Updated changelog 2000-12-07 22:35 rjkaes * src/: thread.c, tinyproxy.c: Fixed a problem with polling for the number of active threads. No longer polls. :) 2000-11-22 23:49 rjkaes * src/ternary.c: Fixed MACRO error. 2000-11-22 23:46 rjkaes * src/tinyproxy.c: Fixed spelling mistake. 2000-11-22 23:46 rjkaes * src/: filter.c, filter.h, reqs.c: Changed the filter_host command to filter_url. 2000-10-23 17:47 rjkaes * ChangeLog: Updated Information. 2000-10-23 17:46 rjkaes * src/ternary.c: In the Key Found code, don't display the string in the debug code since it doesn't exist anymore when we display it. Doh! 2000-10-23 17:44 rjkaes * src/tinyproxy.c: Added the initialization section for the DNS and Anonymous sub systems. 2000-10-23 17:43 rjkaes * src/: anonymous.c, anonymous.h: Added the new_anonymous initialize routine 2000-10-23 17:42 rjkaes * src/: dnscache.c, dnscache.h: Added the new_dnscache routine to initialize the Ternary tree. Also, removed the garbage collection routine. 2000-09-26 01:00 rjkaes * ChangeLog: Updated documentation. 2000-09-26 00:59 rjkaes * src/dnscache.c: Fixed the insert function to handle a failed insert properly. 2000-09-26 00:59 rjkaes * src/: ternary.c, ternary.h: Added the TE_EXISTS return code, and cleaned up the ternary_destroy function. 2000-09-26 00:58 rjkaes * src/: tinyproxy.h, utils.h: Moved the safefree() macro to the tinyproxy.h header. 2000-09-26 00:57 rjkaes * src/: acl.c, reqs.c: Updated the free() calls to the safefree() calls. 2000-09-21 12:58 rjkaes * ChangeLog: Updated documentation. 2000-09-21 12:57 rjkaes * src/tinyproxy.c: There is no LOG_EMERG level, so changed to LOG_CRIT. 2000-09-21 12:53 rjkaes * src/: log.c, log.h: Added the LOG_NOTICE level. 2000-09-15 16:58 rjkaes * src/: grammar.c, grammar.h, scanner.c: These are generated by grammar.y and scanner.l respectively, don't include them in the CVS. 2000-09-15 16:57 rjkaes * src/stamp-h.in: Automatically generated file. 2000-09-15 16:55 rjkaes * src/Makefile.in, doc/Makefile.in: Don't include automatically generated files. 2000-09-15 16:53 rjkaes * install-sh, missing, mkinstalldirs: Don't included automatically generated files. 2000-09-15 16:52 rjkaes * Makefile.in, config.guess, config.sub, configure: Flipping again. :) Don't include any of the automatically generated stuff. 2000-09-14 12:41 rjkaes * ChangeLog, configure.in, src/tinyproxy.h: Need to do a check for the header since it's not a standard header available on all systems. 2000-09-12 14:10 rjkaes * Makefile.in, doc/Makefile.in, src/Makefile.in: Again, needed for configure script. Automatically built by ./reconf 2000-09-11 20:45 rjkaes * config.guess, config.sub: Needed for running configure. Automatically built with reconf 2000-09-11 20:43 rjkaes * configure: Can be made from configure.in (and should be), but I want to be able to check out the source and immediately configure it. 2000-09-11 20:22 rjkaes * doc/tinyproxy.conf: Example tinyproxy configuration file. 2000-09-11 20:21 rjkaes * ChangeLog: We all know what this is. :) 2000-09-11 20:20 rjkaes * acinclude.m4: A M4 macro for finding the various types on the system (typedefs, etc.) 2000-09-11 20:18 rjkaes * Makefile.am, acconfig.h, configure.in: New defaults, and better checking for various features needed by tinyproxy. Looks like fun! :) 2000-09-11 20:16 rjkaes * AUTHORS, BUGS, INSTALL, README, THANKS: Just updating the documentation. 2000-09-11 20:12 rjkaes * src/: grammar.c, grammar.h, grammar.y, scanner.c, scanner.l: These all handle reading the tinyproxy configuration file. 2000-09-11 20:10 rjkaes * src/: ternary.c, ternary.h: Generalized the ternary code which was already being used in anonymous.* now it can be used (and is used) in both anonymous and dnscache 2000-09-11 20:08 rjkaes * src/: acl.c, acl.h: Improved access control semantics. Allows for a finger control for allowing and denying hosts. 2000-09-11 20:07 rjkaes * src/: thread.c, thread.h: tinyproxy now uses a pool of threads to handle connections. All the work for creating new threads, deleting old thread, and generally managing the pool is done here. 2000-09-11 20:06 rjkaes * src/: stats.c, stats.h: This module handles the various stats relating to tinyproxy's functionality. 2000-09-11 20:04 rjkaes * src/: reqs.c, reqs.h: MAJOR RE-WRITE! Read the ChangeLog and look at the source. It's shorter than re-documenting the changes here. :) 2000-09-11 20:03 rjkaes * src/: tinyproxy.c, tinyproxy.h: Fixed the change user/group ability. Log when tinyproxy is using default values rather than specific ones. Cleaned up the command line arguments since tinyproxy now uses a configuration file. Removed the USR1 signal and added the thread creation code. 2000-09-11 20:01 rjkaes * src/: utils.c, utils.h: Removed the xmalloc() and xstrdup() functions. Added the pidfile_create() function. Added the OpenBSD style strlcat() and strlcpy() functions. 2000-09-11 19:57 rjkaes * src/: uri.c, uri.h: Switched to the new logging style and replaced the xmalloc() with straight malloc(). 2000-09-11 19:56 rjkaes * src/: sock.c, sock.h: Needed locking in getpeer_string(). Added mutex locking around the dnscache() call. Removed the global sockaddr and setup_fd variables. Added the socket_blocking() and socket_nonblocking() functions. Gutted the readline() function and replaced it with something similar to the 1.0 version. :) 2000-09-11 19:50 rjkaes * src/regexp.h: Moved back to the for autoconf defines. 2000-09-11 19:47 rjkaes * src/: log.c, log.h: Cleaned up the logging format, and also included logging levels (which are similar to the syslogd format.) 2000-09-11 19:46 rjkaes * src/gnuregex.c: Not using for autoconf anymore, so move back to the format. 2000-09-11 19:43 rjkaes * src/: filter.c, filter.h: Just using standard malloc() since the xmalloc() didn't really add anything useful to the command. 2000-09-11 19:42 rjkaes * src/: dnscache.c, dnscache.h: Removed the custom hash routines. Using the ternary module instead. 2000-09-11 19:41 rjkaes * src/: buffer.c, buffer.h: Cleaned up the source so that the internal structure is no exposed by the buffer.h header. 2000-09-11 19:38 rjkaes * src/: anonymous.c, anonymous.h: Removed the ternary tree code from these files and made it a separate module. 2000-09-11 19:37 rjkaes * src/Makefile.am: Modified to include all the files needed to build tinyproxy, plus the special targets for building the LEX and YACC files. (Also included the GNU license.) 2000-09-11 19:33 rjkaes * doc/tinyproxy.8: Since the tinyproxy program has changed, the manual had to change as well. Documents all the command line arguments, though I think I need to document the configuration file as well. 2000-09-11 19:32 rjkaes * doc/: Makefile.am, TODO: Updated to reflect the new reality of the tinyproxy source code. 2000-09-11 19:31 rjkaes * doc/CONFIG: This was the layout for the purposed config file. This is no more. 2000-09-11 19:27 rjkaes * INSTALL.configure: This was the generic INSTALL file, but the INSTALL file itself is again the generic file. :) 2000-09-11 19:24 rjkaes * src/: config.h, conns.c, conns.h: These files are no longer used within tinyproxy. 2000-06-06 13:58 rjkaes * ChangeLog: Reflect changes made in source. 2000-06-06 13:56 rjkaes * doc/tinyproxy.8: Fixed the links for finding tinyproxy. Thanks to Simon Baker for pointing this out. 2000-04-26 12:31 rjkaes * ChangeLog, src/dnscache.c, src/uri.c: Reorganized (or added) the #include line so tinyproxy would compile cleanly on FreeBSD systems. 2000-04-03 00:00 rjkaes Released tinyproxy 1.3.3 (2000-04-03) 2000-03-31 17:55 rjkaes * ChangeLog, src/reqs.c: Fixed a bug with the path in clientreq. If the path was empty it caused a malformed request to be sent. 2000-03-31 15:15 rjkaes * ChangeLog: A whole whack of changes and bug fixes. 2000-03-31 15:14 rjkaes * src/Makefile.am: Added a line for the anonymous.* files. 2000-03-31 15:14 rjkaes * src/config.h: Changed the socket time out to 10 secs. 2000-03-31 15:13 rjkaes * src/reqs.c: Updated the anonheader function to use the new anonymous API. Removed the hack for the POST method in clientreq. 2000-03-31 15:10 rjkaes * src/sock.c: Completely rewrote the readline function. 2000-03-31 15:09 rjkaes * src/: buffer.c, buffer.h: Added the working_* fields as a scratch pad for readline(). 2000-03-31 15:08 rjkaes * src/: tinyproxy.c, tinyproxy.h: Removed the allowedhdr_s structure since it is now accessed through anonymous.* 2000-03-31 14:56 rjkaes * src/: anonymous.c, anonymous.h: Moved the anonymous header code into it's own file to make it easier to update. 2000-03-29 11:19 rjkaes * ChangeLog: Updated to list changes in src/reqs.c and src/dnscache.c 2000-03-29 11:18 rjkaes * src/dnscache.c: Included the header. 2000-03-29 11:17 rjkaes * src/reqs.c: Fixed a bug with the clientreq function which was incorrectly setting the clientheader flag and causing _all_ headers to be sent even in anonymous mode. 2000-03-28 11:44 rjkaes * ChangeLog: Updated ChangeLog entry for new fix. 2000-03-28 11:41 rjkaes * src/reqs.c: Fixed another NULL bug with the uri->authority. If an badly formed request was made in the form of http:\\www.somewhere.com/ tinyproxy would SEGV. This has been corrected. 2000-03-28 11:21 rjkaes * ChangeLog: Updated to reflect changes in src/reqs.c 2000-03-28 11:19 rjkaes * src/reqs.c: Fixed a NULL pointer bug in clientreq. If the SCHEME in the URL was NULL the program would SEGV. This was caused by the error logging code. 2000-03-12 19:56 rjkaes * src/config.h: Remove the defines for DEFAULT_* and UPSTREAM (they've been moved into acconfig.h and configure). 2000-03-12 19:55 rjkaes * ChangeLog: List all the changes which has occurred on the program. 2000-03-11 15:43 rjkaes * acconfig.h: Added the support for the upstream proxy and also made the defaults for the LOGFILE, USER, and PORT. 2000-03-11 15:37 rjkaes * src/: dnscache.c, reqs.c, tinyproxy.c, tinyproxy.h: Included the changes needed to re-add the upstream proxy option. 2000-03-11 15:36 rjkaes * doc/tinyproxy.8: Updated the manual to reflect all the options, plus provide additional information concerning the changes made to some of the options. 2000-03-11 15:35 rjkaes * configure.in: Re-ordered some of the arguments. Included the support for the Upstream Proxy. 2000-03-11 15:34 rjkaes * src/: Makefile.in, defines.h.in: Once again, these files are made automatically, don't include them. 2000-03-11 15:33 rjkaes * doc/Makefile.in: Again, the file is generated automatically, so don't include it. 2000-03-11 15:32 rjkaes * Makefile.in, aclocal.m4, configure: These files are generated by reconf, so don't include them in the CVS. 2000-02-16 12:32 sdyoung * AUTHORS, COPYING, ChangeLog, INSTALL, Makefile.am, Makefile.in, NEWS, README, THANKS, aclocal.m4, BUGS, INSTALL.configure, acconfig.h, configure, configure.in, install-sh, missing, mkinstalldirs, reconf, src/Makefile.am, src/Makefile.in, src/defines.h.in, src/stamp-h.in, src/filter.c, src/buffer.c, src/buffer.h, src/config.h, src/conns.c, src/conns.h, src/dnscache.c, src/dnscache.h, src/gnuregex.c, src/log.c, src/log.h, src/reqs.c, src/reqs.h, src/sock.c, src/sock.h, src/tinyproxy.c, src/tinyproxy.h, src/uri.c, doc/Makefile.am, doc/Makefile.in, doc/TODO, src/filter.h, src/gnuregex.h, src/regexp.h, src/uri.h, src/utils.c, src/utils.h, doc/CONFIG, doc/HTTP_ERROR_CODES, doc/RFC_INFO, doc/report.sh, doc/tinyproxy.8: Initial revision 2000-02-16 12:32 sdyoung Released tinyproxy 1.3.2 (2000-02-16) * AUTHORS, COPYING, ChangeLog, INSTALL, Makefile.am, Makefile.in, NEWS, README, THANKS, aclocal.m4, BUGS, INSTALL.configure, acconfig.h, configure, configure.in, install-sh, missing, mkinstalldirs, reconf, src/Makefile.am, src/Makefile.in, src/defines.h.in, src/stamp-h.in, src/filter.c, src/buffer.c, src/buffer.h, src/config.h, src/conns.c, src/conns.h, src/dnscache.c, src/dnscache.h, src/gnuregex.c, src/log.c, src/log.h, src/reqs.c, src/reqs.h, src/sock.c, src/sock.h, src/tinyproxy.c, src/tinyproxy.h, src/uri.c, doc/Makefile.am, doc/Makefile.in, doc/TODO, src/filter.h, src/gnuregex.h, src/regexp.h, src/uri.h, src/utils.c, src/utils.h, doc/CONFIG, doc/HTTP_ERROR_CODES, doc/RFC_INFO, doc/report.sh, doc/tinyproxy.8: Initial CVS checking of tinyproxy - version 1.3.2. 1999-12-24 20:33 sdyoung Released tinyproxy 1.3.1 1999-12-03 23:21 sdyoung Released tinyproxy 1.3.0 (1999-12-03 unconfirmed)
