The 3.17.3 release has no external api changes (but does fix a few api
implementation bugs so check the details below).
New minor features:
1) Add new option to spflooder. The -n option allows a fixed
"number of members" to be set. This then activates a multi-sender flow
control algorithm to allow flooding tests with several senders. All of
the processes need to join the group (i.e. they cannot be
-wo (write-only)) but not all processes have to send. This allows easy
testing with differing numbers of senders (just change how many
spflooders start with -ro and how many do not).
2) Modify monitor so it will run correctly on Windows. This was done by
modifying monitor.c so it can also build as a threaded program and
on windows will use multiple threads to send/recv updates and get
user input. (A POSIX thread option is also added).
3) Add new Alarm priority flag to print a line with no datestamp
(for multi-line output).
4) Add new Windows VC++.Net project files to daemon/win32_msvc_net.
The current project files in daemon/win32 remain as they can be used
in VC++ (version 6).
The list of bugfixes is:
1) Fix memory leak in Skiplist. Reported by Taj Khattra, patch by Theo
Schlossnagle.
2) spuser,spflooder, and spmonitor fixed to print correct name in help.
Patch by Daniel Rall.
3) Fix incorrect alarm printing where WARNING messages generated by
older Alarm() interface were not printed.
4) Fix a bug in the Windows build using VC++ of thread-safe libtspread.lib.
Bug and fix by Jacob Green.
5) Fix bug in libspread where if the groups array or message body passed
to SP_recv* was too small, the mess_type field returned would be truncated
and the sender field was not returned. They are both now returned
correctly. Bug report and partial fix provided by John Schultz.
6) Fix bug where SP_Join and SP_Leave do not report an error if a group name
is too long (instead they truncated it) Reported with fix by David Parker.
** Warning, this could break buggy applications who use long groups and
assume the name is truncated.
7) Cleanup compile warnings where E_queue() used with no-parameter
functions
(not all uses fixed) and fix incorrect use of signed int with strlen().
8) Fix few cases in flooder.c and user.c that did not use the defined
MAX_MESSLEN constant. Tested to verify that increasing
MAX_SCATTER_ELEMENTS in scatter.h and the MAX_MESSLEN defines in user.c
and flooder.c is sufficient to support arbitrarily large message sizes
with Spread. This is NOT recommended, but several people do it anyway :-)
9) Make E_delay() work on Win32.
10) Added check that a segment using localhost (i.e. 127.0.0.255) is NOT in
a spread.conf with any other segments using real IP addresses. This
configuration will not work correctly and is usually because the example
localhost configuration provided with Spread is added to. This check will
cause the daemon to exit immediately after parsing the config file.
11) Fix bug where if more then 22 daemons start at the same time, some will
crash or the membership will not complete correctly. This bug was
reported by several people including Jesse Noller.
12) Fix Java spread connection problem where several threaded connections
from same process cause unexpected connection failures. Reported by
Brian Moseley, idea of fix by Ryan Caudy, patch by Jonathan Stanton.
13) Fix EVS bug where AGREED messages may be delivered before a transitional
signal on some daemons and after it on others. Bug found and patch
created by Ryan Caudy.
14) Make SP_connect_timeout() calls non-blocking for the actual 'connect()'
call. This should fix the issue reported by Shlomi Yaakobovich where a
hung daemon causes new connections to also hang in connect. Also includes
slight cleanup of connect code path.
Ver 3.17.2:
--------------
1) Fix daemon quit when multiple interfaces are configured as "D" daemon
interfaces in the spread.conf file. Bug reported by Orit Wasserman.
2) Updated url for Java 'ant' build system. Patch by Daniel Rall.
3) Fix group_id bug that causes incorrect vs_sets. Patch by Ryan Caudy.
4) Fix spread.conf parser so it validates the machine names in segments
and forces them to be less then MAX_PROC_NAME. Patch by Mikhail Terekhov.
5) Minor fix to Mac OS X compilation so library softlinks do not fail the
second time make is run.
6) Alarm() changes to support priority levels on each Alarm() call.
7) Fix crash by improving packet accounting when a client connected to a
singleton daemon sends a large broadcast. Reported by David Shaw.
8) Fix bus errors on Sparc & Alpha for message buffer integer assignment.
Reported by Greg Shebert; tested and patched Mikhail Terekhov.
9) Verify daemon names in spread.conf are unique. If non-unique names are
provided in spread.conf, configuration will be rejected and daemon will
not start. Suggested by Tim Peters.
10) Zero buffer in c library before sending multicast.
Reported by Panagiotis Kougiouris.
11) Send fewer lookup probe messages when only a single segment is configured.
12) Remove extra token rotations when no messages are sent. Will decrease
network packet overhead.
13) Make mailbox and service in sp.h a typedef instead of a #define. Suggested
and patched by Steven Dake.
14) Fix small endianness error in sp.c where the mess_type field may not be
correctly converted for different endian platforms when the SP_*_recv calls
return a BUFFER_TOO_SHORT or GROUPS_TOO_SHORT error.
15) Change alarm tag for security prints from SEC to SECURITY because of conflict
with sys/time.h header.
16) Documentation fix to SP_receive man page to correct fields for self-leave
membership messages.
17) Update of email addresses in copyright statements and headers.
18) Windows binary libraries now built as libspread and libtspread like other
platforms.
