libivy-java (1.2.17) unstable; urgency=low
* debian wheezy : modifications in Makefile,src/Makefile, java.mk, debian/control
-- JP Imbert <jean-paul.imbert@enac.fr> Tue, 02 Oct 2012 16:15:21 +0200
libivy-java (1.2.16) unstable; urgency=low
* New API:
- IvyClient.getRegexps no longer returns an Enumeration, but a
Collection
* Internals:
- switched to a lot of synchronized connections, in order to avoid
concurrent modifications Exceptions I was unable to prevent so far
-- Yannick Jestin <yannick.jestin@enac.fr> Fri, 27 Apr 2012 10:47:21 +0200
libivy-java (1.2.15) unstable; urgency=low
* Internals:
- sets the default buffersize to 4096 bytes. This can be adjusted
through the use of the IVY_BUFFERSIZE jvm property (java
-DIVY_BUFFERSIZE=200 , e.g. ) This is intended to be similar to the
ivy C implementation, and *should* fix the buffering issues of
applications requiring a lot of small data exchanges (e.g:
transmitting mouse mouve at a high rate).
* New API:
- added sypport to the Swing Dispatch Thread in the bindAsyncMsg api.
this breaks the former API. Use BindType.SWING as the latter argument.
- severe problems throws RuntimeException instead of System.exit(),
allows code reuse.
- many methods now are protected, with accessors
- removed unread fields (Ivy.domainaddr, e.g.)
- ready message is set to appName + " READY" if null has been
provided, like in the C# api
- lowercase CheckRegexp to checkRegexp (bad practice, thanks to
FindBugs).
* Doc:
- javadoc updated (a bit)
- removed protected methods from javadoc
switch to apache fop + docbook for documentation translation
* Internals:
- added a lock mechanism to be sure that once a connexion
has been initiated, the ready message will be sent before
stopping the bus now: Ivy b = new Ivy(...); b.sendMsg("coucou");
b.stop(); should send messages (at least the ready message)
if there is a connexion attempt made before b.stop() is
effective. To be sure, there is a 200ms delay before b.stop()
can be effective (the Threads stopped, the sockets closed)
- IMPORTANT ! switch from gnu regexp (deprecated) to the
built in java
regexp.
- IMPORTANT ! Reintroduced a mechanism to allow the drop of a double
connexion attempt.
- use new synchronization scheme with locks (app socket, structures)
- add generic types to declarations, the code now won't ompile on java
prior to the 1.5 platform
- fixed a potential null pointer dereference on quit (thanks to
findBugs)
- remove the Thread.start() from the constructor, to avoid mulithread
issues. see
http://findbugs.sourceforge.net/bugDescriptions.html#SC_START_IN_CTOR.
now ,we have to call IvyClient.start() after it has been created
- IvyWatcher tries to fix a lock on accept() by becoming a Thread
instead of runnalbe (see tests/test2).
* Internal performance issus
- use of stringbuffers to concatenate strings, instead of using +,
which could lead to a quadractic cost in the number of iteraction (the
growing string was recopied in each iteration).
- when possible, move the regexp Pattern.compile in static areas, to
avoid multiple calls.
- recopy the filter String[] in setfilter, to avoid exposing internal
representation (unsafe operation).
- in many areas, e.g. Hashtable keys, use autoboxing for the creation
of Integer (instead of new Integer(int). This alows caching, avoids
object allocation, and the * code will be faster.

libivy-java (1.2.13) unstable; urgency=low
* disables the Nagle's socket algorithm ( TCP_NO_DELAY = 1 )
* adds try catch blocks for RE constructors ( new Jakarta Regexp ? )
* updates of documentation ( jafter, sgml file )
-- Yannick Jestin <yannick.jestin@enac.fr> Wed, 25 Jul 2009 16:51:21 +0100
libivy-java (1.2.12-2) unstable; urgency=low
* etch fixes
* NEW BUG identified and not solved: multicast rendez vous is broken
-- Yannick Jestin <yannick.jestin@enac.fr> Wed, 17 Jan 2007 16:51:21 +0100
libivy-java (1.2.12) unstable; urgency=low
* (re)introducing Ping and Pong in the protocol and in IvyClient api
-- Yannick Jestin <yannick.jestin@enac.fr> Mon, 24 Jul 2006 15:32:34 +0200
libivy-java (1.2.11) unstable; urgency=low
* major documentation update ( programmers's guide )
* debian packaging system modified to use dhelper
* added jafter and jdaemon in the shell scripts
* added the ID in the UDP broadcast
-- Yannick Jestin <yannick.jestin@enac.fr> Thu, 20 Jul 2006 14:48:00 +0200
libivy-java (1.2.10) unstable; urgency=low
* modified the domain parsing to allow -b :3110 e.g. , it is still a bug ...
-- Yannick Jestin <yannick.jestin@enac.fr> Tue, 18 Jul 2006 18:49:19 +0200
libivy-java (1.2.9) unstable; urgency=low
bug remaining
- the overhead is quite important on a loaded setup
bugfixes
- unexpected disconnections after the broadcast
new features
- Ivy.setFilter() aka message classes, reduces the number of regexp
matching, improves performance especially when there are *many* clients
and *many* regexps, most of them ^bounded . See doc for details
- java -DIVYRANGE=4000-5000 allows the choice of service ports within a
specific range, for instance on firewall configurations.
- modification of the IDP broadcast ( see mailing list for details )
- .time and .bound commands in jprobe
-- Yannick Jestin <jestin@cena.fr> Thu, 22 Nov 2005 23:09:00 +0100
libivy-java (1.2.8) unstable; urgency=low
bugfixes
- fixed the "start stop start stop" bug reported by Francis Jambon (
thanks alot, Francis ! )
- validates against the 1.4 jakarta regexp library.
- IvyWatcher had a static structures leading to a nasty bug when several
Ivy Agents were in the same JVM.
new features
- Ivy.getWBUId() returns a "wanna be unique Id", quite useful when
performing queries. It looks like IDTest0:1105029280616:1005891134.
- Ivy.getDomainArgs(String,String[]) is a cheap and handy way of finding out
the domain, based on the DEFAULT_DOMAIN, then on the IVYBUS property, then on
the -b domain command line argument. Be sure to use it !
- added the After tool
- Probe, After and IvyDaemon going to tool
- fixed the jprobe shell script to honor $IVYBUS environment variable
-- Yannick Jestin <jestin@cena.fr> Thu, 22 Nov 2005 23:09:00 +0100
libivy-java (1.2.7) unstable; urgency=low
bugfixes
- no more the infamous unBindMsg() reported by Matthieu
- *complex* algorithm to disallow multiple instances of the same agent
when launched with multiple broadcast addresses, some of them being
received twice by a remote agent X, X trying to connect twice ...
It should fix both Francis's WiFi bugreport, and Jean-Paul Stress' bug
new features
- Probe allows .where .dieall-yes-i-am-sure .bound and .bound CLIENT
code cleanup
- minor fixes for acecssing static final values
-- Yannick Jestin <jestin@cena.fr> Thu, 23 Dec 2004 17:21:00 +0100
libivy-java (1.2.6) unstable; urgency=low
bugfixes
- major cleanup to handle simultaneous connections, e.g., between two
busses within the same process ( AsyncAPI test is very stressful )
I made an assymetric processing to elect the client that should
disconnect based on the socket ports ... might work...
- jakarta regexp are not meant to be threadsafe, so for match() and
compile() must be enclaused in a synchronized block
- now sends back an error message when an incorrect regexp is sent
the message is supposed to be readable
- IvyWatcher now uses a new buffer for each Datagram received, to prevent an old bug
debian package
- the package name goes to libivy-java,
- examples have been added in the documentation and corrected to honor the
new lib
documentation
- the manual has been heavily updated, and C++ has been left out.
new features
- Ivy.waitForMsg(regexp,timeout) and Ivy.waitForClient(name,timeout) make
the synchronization with other Ivy agents easier. Wait "forever" if
timeout is null.
- use Ivy.protectNewLine(true) to ensure encoding and decoding of newline
as 0x1A. As the encoding and decoding cost a little more CPU and is not
yet standardized in the Ivy protocol, use it at your own risk.
- IvyClient now sends back an error message when an incorrect regexp is sent
the message is supposed to be readable
- uses apache jakarta-regexp instead of gnu-regexp ( see
http://jakarta.apache.org/regexp/ ), we gain a compatibility with Perl
and the new ivy-c 3.4.6 :)
- no more java ping in Probe ...
- use bindAsyncMsg(regexp) to perform each regexp in a new Thread. This
can avoid hangups when you have lengthy callbacks ( calculation, etc ).
There is no asynchronous sending of message because the tests are sooooo
unsuccessful
API changes
- Ivy changed changed the semantic of -b a,b:port,c:otherport if no port is
specified for a, it take the port from the next one. If none is
specified, it takes DEFAULT_PORT
- IvyWatcher's getDomain now sends IvyException for malformed broadcast addresses
-- Yannick Jestin <jestin@cena.fr> Tue, 29 Jul 2004 19:28:00 +0100
ivy-java (1.2.4) unstable; urgency=low
bugfixes
- resists when a non Ivy Agent broadcasts on our address
- invokes disconnect() on a normal IvyClient end of run()
- bus.start(null) now *really* starts on IVYBUS property or 127:2010 if the
property is not set
- bugfix J007 : breaks connexions with remote clients using a faulty
protocol, ignore subscriptions to faulty regexps.
- bugfix J006 : invokes the applicationListeners's disconnect method at the
end of the run() loop
- the IvyWatcher accepts connexions from remote hosts with the same port
number. Closes a possible bug, yet to check thoroughfully...
- bugfix J005 : the IvyWatcher's loop doesn't break on faulty broadcasts,
belonging to non ivy application, e.g.
- major rewrite of the internals of the Ivy class structure
new features
- added a sendToSelf(boolean) method in the Ivy class to allow the
sendMsg() to trigger our own callbacks. Default is false.
API Changes (WARNING, you might have to recompile you applications)
- changed the API for Ivy.sendMsg and IvyClient.sendDirectMsg, both function
can now raise an IvyException if the message contains \n or \0x3
- changed the API for IvyApplicationListener ( die now requires a String
argument ).
- changed the API for Ivy.bindMsg(). It now raises an IvyException if the
regexp was not compiled successfully (e.g.: "(.*").
- added an IvyBindListener and Ivy.addBindListener, Ivy.removeBindListener
order to hook callbacks upon reception of bind requests. It is now
possible to write a decent ivy monitor program. JProbe has been rewritten
this way and now displays the subscriptions in real time, not only at
startup ( should I file a bugreport against ivy-c ? )
- Probe can send messages to itself, with the -s command line switch
-- Yannick Jestin <jestin@cena.fr> Tue, 18 Feb 2003 16:49:00 +0100
ivy-java (1.2.3) unstable; urgency=low
- debian packaging corrected, now build-depends on java-compiler and
depends on java-virtual-machine. I should switch to libivy-java.
The classes are not unpacked in the repository, but whithin a jar file.
- added a jprobe shell script
- added the testbench code in the documentation
- Many bugfixes thanks to a new testbench
* the datagram sender is in its own thread. Now works with jdk1.2
* IvyClient doesn't loop any more on a remote disconnexion
