tinyproxy/ChangeLog

2002-05-31  Robert James Kaes  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	Released tinyproxy 1.5.0 (2002-05-09)

2002-05-08  Robert James Kaes  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* src/thread.c (thread_main): Added code to check if tinyproxy is
	being killed by the user.

2001-12-28  Robert James Kaes  <rjkaes@flarenet.com>

	* src/thread.c (thread_main): Added code to detect errors in the
	accept() function.

2001-12-23  Robert James Kaes  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* src/tinyproxy.h: Add a test for the MSG_NOSIGNAL define, so it's
	apparently a non-standard extension to send(). Also, moved the
	<sys/resource.h> include after the includes for the various time
	include files.

2001-12-19  Robert James Kaes  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	Released tinyproxy 1.4.2 (2001-08-29)

2001-08-28  Robert James Kaes  <rjkaes@flarenet.com>

	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  <rjkaes@flarenet.com>

	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  <rjkaes@flarenet.com>

	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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	Released tinyproxy 1.4.0 (2001-06-24)

2001-06-06  Robert James Kaes  <rjkaes@flarenet.com>

	* configure.in: Total reorganization.

2001-06-04  Robert James Kaes  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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  <rjkaes@flarenet.com>

	* 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.

	* 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 <config.h> 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 <defines.h> for autoconf anymore, so
	move back to the <config.h> 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 <sys/types.h> 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 <sys/types.h> 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.
