	but is nowhere declared.

2001-09-07  [ Ela ]  <[e-mail]>

	* util.c (svz_syserror): Do not let the system allocate error
	message buffer; provide it instead.

	* pipe-socket.c (svz_pipe_startup): New function. Tries
	to load the CancelIo() symbol from `Kernel32.dll' under

	NT 4.x and above only. Called from svz_boot().

	descriptors non-blocking under Win32.

2001-08-17  [ Ela ]  <[e-mail]>

	* Makefile.am (libserveez_la_LDFLAGS): Added release information
	onto the core library.

	* server.c (svz_server_configure): Checking the validity of
	the configuratiom item addresses. These must reside inside the
	default configuration address range.

2001-08-13  [ Ela ]  <[e-mail]>

	* socket.c (svz_sock_check_request_size): New function. Checks
	for fixed size packets if the boundary itself is NULL, but the
	boundary size is valid.

2001-08-12  [ Ela ]  <[e-mail]>

	* server-core.c (svz_sock_table_create, 
	svz_sock_table_destroy): New functions called from svz_boot()
	and svz_halt().

	callers.

2001-07-31  [ Ela ]  <[e-mail]>

	* coserver/coserver.c (svz_coserver_check): Do not restart

	* passthrough.c: Added a new subset of functions called 
	svz_envblock_*() which can be used to setup environment blocks
	system independent.

	* coserver/coserver.c (svz_coserver_check): Coservers get 
	automagically restarted if the number of instances decreases or
	buffer overrun is in sight.

2001-07-11  [ Ela ]  <[e-mail]>

	* core.c (svz_sendfile): Added quite a lot comments for weird
	TransmitFile() on Win32.

2001-07-07  [ Ela ]  <[e-mail]>

	collisions with Windoze's headers.

2001-07-05  [ Ela ]  <[e-mail]>

	* core.c (svz_sendfile): Partly figured out how sendfile()
	works on OSF4.0g (True64).

2001-07-03  Stefan Jahn  <[e-mail]>

	* server-core.c (svz_sock_setparent): Set the parent only if
	both parent and child are valid.

2001-06-21  [ Ela ]  <[e-mail]>

	* coserver/coserver.c (svz_coserver_start): Fixed memory leak
	and segmentation fault due to the failure of that function 
	(Too many open files).

	* portcfg.c (svz_portcfg_create): This is a real function now.

	* pipe-socket.c (svz_pipe_listener): Create fifo files with the
	permissions and user/group as requested by the port configuration.
	(svz_pipe_alloc, svz_pipe_destroy): New functions.

	* pipe-socket.c (svz_pipe_connect): Using the given permissions
	in order to connect to named pipes.

2001-06-19  [ Ela ]  <[e-mail]>

	* pipe-socket.c (svz_pipe_check_group): Consistency check
	for the given group name of a pipe.

	* dynload.c (svz_dynload_path_get): Do not use duplicate path
	information.

2001-06-13  [ Ela ]  <[e-mail]>

	* array.c: Modified all functions that they can handle NULL
	arguments.

	* array.h: Removed all inline functions and macros. The macros
	would have never been working...

2001-06-12  Raimund 'Raimi' Jacob  <[e-mail]>

	* util.c (svz_log): svz_logfile is checked for feof() or ferror()
	before any output is done. You can now kill a process we pipe
	log messages to without serveez going 'netscape' (using 100% cpu
	while being inresponsive/unusable).

	* server-core.c (svz_signal_handler): In case you didn't know:
	signal handlers have to be reentrant, at least on my machine.
	We received SIGCHLD while a SIGCHLD was running. Now, that
	wouldn't have been a problem when strsignal(3) whouldn't
	have caused a deadlock in the libc (read that again).

	We added a mechanism to strsignal() all signals before the
	server loop starts so that we can have a reentrant
	svz_strsignal() function. on a related note: linux defines
	64 signals in <bits/signum.h>. kill(1) however allows
	0 to 64 to be command line arguments... which makes 65 total
	signals :-).

2001-06-10  [ Ela ]  <[e-mail]>

	* array.h (svz_array_foreach): Fixed a bug in the iteration
	macro.

	* array.c (svz_array_dup, svz_array_strdup): New functions.

2001-06-08  [ Ela ]  <[e-mail]>

	* icmp-socket.c (svz_icmp_check_packet): Using configured
	ICMP type field of the related port configuration.

2001-06-07  [ Ela ]  <[e-mail]>

	* portcfg.c (svz_portcfg_destroy): Buf fix: Do not check
	port configuration hash if not yet existing.

	* dynload.c (dyn_load_library): Try to load a shared library
	containing a server definition. Use the environment variable
	SERVEEZ_LOAD_PATH with additional search paths.

2001-06-01  [ Ela ]  <[e-mail]>

	* interface.h (svz_interface_foreach): New macro.
	(struct svz_interface): Renamed this structure.

	* interface.c (svz_interface_get): New function.

	* server-core.c (svz_sock_setreferrer, svz_sock_setreferrer): 
	Two new functions replacing the `referrer' pointer in the
	socket structure. Used by pipe server to identify child and
	parent.
	
	* server.h (struct svz_servertype): Renamed `varname' to
	`prefix' and `name' into `description' which describes the
	usage a bit better.

	* socket.h (struct svz_socket): New field: `port' specifies
	the port configuration of a listener socket. This change was 
	necessary because non-connection oriented protocols were using
	the `sock->cfg' field for both server configuration and port
	configuration.

	* server.h: Renamed all `ITEM_' macros into `SVZ_ITEM_'. 
	Changed all callers.

2001-05-21  [ Ela ]  <[e-mail]>

	* pipe-socket.h, core.h, util.h, snprintf.h, alloc.h: 
	Replaced all occurences of size_t, mode_t, gid_t, uid_t, 
	off_t etc. by its normal C types.

2001-05-20  [ Ela ]  <[e-mail]>

	* server.c (svz_server_configure): Added code for 
	configuring a boolean value.

	* boot.c: Moved runtime checkable flags from `util.c' here
	and prefixed them with `svz_'.

	* server.h (SVZ_REGISTER_BOOL): New macro for registering a
	boolean value within a server type configuration.

2001-05-19  [ Ela ]  <[e-mail]>

	* Renamed a very lot functions in order to get the core library
	into a defined namespace. Therefore also changed all the callers.

	* raw-socket.c: Prefixed the functions. Changed callers.

	* icmp-socket.c: Prefixed symbols.

	* udp-socket.c: Prefixed all symbols. Changed callers.

	* pipe-socket.c: Prefixed functions with `svz_'. Changed
