Version NEXT

Version 2.8.1b29 - 24 Aug 2019

        added scons command line argument without-fspscan=yes for building

	  without fspscan

	fhostcmd: Fixed output of FSP_TRACE variable for Bourne style shells

	correctly initialize to zero client packet sent statistic counter

	note default timeout values in fsp_env man page

	setting environment value FSP_TIMEOUT to <=0 uses 4byte maxint value

	  error found by Clang.

	allow docbook dsssl stylesheets to be specified at scons command line

	always validate path in SETPRO and MKDIR even if packet is resent and

	  no action will be taken. This is needed to avoid uninitialised

	  pointer access during reply. Found by Clang.

Version 2.8.1b26 - 1 Oct 2009

	fver now reports if server can process extra data in input packets.

	  fspclient did that for a long time. This field is used by fspd

	  2.8.1 beta 21 or newer.

	Server version string sent as response to CC_VERSION command have

	  no longer \n appended to it. Old FSP used it but fver client

	  command can handle server strings without \n for quite a long

	  time, so i decided to remove it. It is bad idea to terminate

	  version strings by \n while it is not required by FSP protocol.

	glob() function used in FSP clients renamed to bsdglob because it

	  clashed with glob() function in newer Linux glibc resulting in

          segfaults.

	non continuous upload detection fixed. Now detection works as follows:

	  if you are trying to upload past end of file, fspd will report that

	  you are trying to create hole in file.

	  if you are seeking backwards more than 1 packet size fspd will

	  report noncontinuous upload. Most likely port from old unfinished

	  download was reused.

	We can now reupload last block which can happen if fspd server is

	  restarted and reply to upload command is lost on way from server

	  to client.

	Check for overwriting uploaded files in fspd was reversed by mistake.

	  Now if you want to overwrite file you must have permission for

	  deleting and adding files or be directory owner.

	Turning on debug in SCons turns on maintainer mode also.

	Upload starting at zero position are now always allowed no matter if

	  source port was reused or not. Old code did that but not over

	  server restarts.

	INFO file updated with fresh information

	fsetupcmd and fhostcmd now reject port number > 65535

	fsetupcmd - code cleaned a bit. Error message is now

	  fsetup: No host given! instead of fhost:

	fsetupcmd got -l option. It lists all known fsp servers collected

	  from .fspsites files.

	fpwd command from setup.sh now prints site name instead of ip

	  address if possible.

	SCons now check if CC compiler works. We need SCons 1.1 or greater

	  for building FSP now.

	Large file support on Linux is now correctly detected.

	Error codes added to CC_ERR command in PROTOCOL. It was long wished

	  feature from ISV. Now there is standard way how to pass error codes

	  from server to client. No such codes are defined yet, but you can

	  use custom error codes in range 0xF000 - 0xFFFF. because no such

	  codes are defined fspd do not sends them in error message, but it

	  now correctly zeroes bb_pos field in CC_ERR reply to indicate

	  that extended error code status is not attached to message. Old

	  fspd versions left this field untouched - it will contain request

	  bb_pos in most, but not all cases. Because we indicate size of

	  extra data to be received, this extended error handling is

	  compatible with "plain FSP over serial" standard.

	Code portability improved. Now we don't need to check sizes of

	  predefined types because we are now using ISO C types. Only thing

	  what we need to know is if largefiles are supported or not.

	  If SCons cant run test program for sizing off_t for any reason,

	  it defaults to 4 (no largefiles, 32-bit system).

Version 2.8.1b25 - 10 Sep 2009

	GNU autotools build system was entirely replaced by SCons

	corrected misleading comment in client/lib.c

	default packetsize changed to do best fit into maximum 1500 MTU

	  Ethernet frame = 1460. This is needed for speedup the booting of

	  Etherboot clients

	PROTOCOL: when computing checksum declare *t as unsigned char * type

Version 2.8.1b18 - 25 Nov 24 2003

	This is MINIMUM REQUIRED VERSION for applications which are using

	  javafsp library, only download machine atm. Javafsp library will

	  be released shortly as separate package.

Version 2.8.1b4 -- 30 March, 2001

---------------------------------------------------------------------------

New maintainer: Radim Kolar hsn/at/sendmail.cz  now maintains FSP codebase.

---------------------------------------------------------------------------

	1) Eliminated a lot of warnings when compiling with -Wall.

	2) Moved to autoconf 2.12. Replaced old m4 macros with Autoconf's.

	   All autoconf's values are cached.

	3) Makefiles are now generated by automake.

	4) include/tweak.h.in is generated by autoheader.

	5) Added faq.html.

	6) Server now writes more messages when in debug mode. Debug mode is

	   disabled when running in inetd mode. Daemonize is disabled when

	   running in debug mode.

	7) Server accepts command line switches -d (debug) -i (inetd) 

	   -v (version) -p <port> (Alternate port number). Uses now getopt.

	8) Server has now configurable timeouts, maximal packetsize,

	   directory and file handles caches.

	9) REMOVED VMS part vms/ and vms_src/. Is was out of date.

	10) Removed file MACHINES. It was out of date. After my changes in

	    autoconf, it may not compile on non-Linux systems.

	11) Implemented a check for reliable signals in the configure script.

	12) Return type of signal handler is detected in configure script.

	13) ANSI prototypes are now used, if host compiler supports them.

	14) When server is running in read-only mode, server send this

	     information to clients, instead generic "Permission denied".

	15) Access checking and uploading was fixed. Now works.
