Version 1.1.5:
This is a minor feature and maintenance release
New features
oncrpc
- The ONC/RPC library has been extended by introducing the use of Java enumerations in favour of Java interfaces for mapping
enumerations specified in XDR and RPC specifications, respectively.
- The new class
org.acplt.oncrpc.XdrHashCode introcudes a common hash method for implementations of the interface
org.acplt.oncrpc.XdrAble. Disguised as an XDR encoding stream, the hash code of an object is calculated by passing
an XDR encoding run (which in turn visits and therefore considers each field of such an object).
jrpcgen
- In previous releases, enumerations used to be mapped by Java interfaces. Starting with this release, they are mapped by Java enumerations,
which becomes the default mapping for enumerations. Backwards compatibility is given, when passing the flag
-noEnum to jrpcgen.
- Generating at least either a client or a server stub includes generating a program interface reflecting the program specification
given in the x-file.
- Comments starting with
/** in an x-file are considered as Java documentation and are passed to the generated Java
sources.
- By default generated classes for structures and unions get an additional constructor, the so called value constructor.
This enables initialization of a new object at construction time. Generation of value constructors can be deactivated by passing
the flag
-noValueCtor to jrpcgen.
- By default generated classes for any type except for Java enumerations get a
toString() - method, building a string
consisting of the name / value pairs of the object fields. The generation of the toString() - methods can be
deactivated by passing the flag -noToString to jrpcgen.
- By default generated classes for any type except for Java enumerations get an
equals() - and a
hashCode() - method. The generation of the equals() - and the hashCode() - method
can be deactivated by passing the flag -noEquals to jrpcgen.
Fixed issues
jrpcgen
- Declared indirections in an x-file, for example
int *optionalID, whose types are mapped to Java primitives like
int and boolean used to be declared as usual fields in the generated Java code
(int optionalID for the given example). Accordingly,
the generated coding methods of such fields missed the optional character given in the specification of the x-file. Starting with this release,
optional data mapped to Java primitives is generated with their wrapper classes like java.lang.Integer instead of
int and java.lang.Boolean instead of boolean. Using an object instead of
the primitive gives the corresponding fields the optional character and eases the coding of these fields as optional data.
Version 1.1.4:
This is a minor maintenance release
Fixed issues
- Reported issue Remove bundled libraries:
The JrpcgenSHA (org.acplt.oncrpc.apps.jrpcgen.JrpcgenSHA) interface was based on a bundled implementation of
the SHA-1 algorithm introduced by the GNU classpath (gnu.java.security.provider.SHA.java). The change
proposed in the reported issue has been patched into this release.
- Reported issue Incorrect Free Software Foundation address:
The address of the GNU Free Software Foundation has been changed from 675 Mass Ave, Cambridge, MA 02139, USA to
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Miscellaneous
- The test classes have been moved to the test source paths of the corresponding modules.
- A small bug returning false to the first custom authentication scheme registered
to a server stub has been fixed.
Version 1.1.3:
This is a minor maintenance release
Changed packaging of the ONC/RPC runtime package
The OSGi package bundle of the ONC/RPC runtime library now exports all of the ONC/RPC runtime packages.
Version 1.1.2:
This is a minor maintenance release
Changed packaging of the ONC/RPC runtime package
The Maven packaging of the ONC/RPC runtime package has been changed to bundle,
adding OSGi bundle information to the manifest.
Version 1.1.1:
This is a minor maintenance release.
Reorganization of the project
The project has been converted into a Maven project. It has become a multi-module project,
containing the modules oncrpc, jrpcgen,
jportmap, maven-plugin and
information. The transition into a Maven project intends on:
- separating the project into its modules.
- deploying it to Maven central.
- introducing a Maven plugin for generating Java sources out of an x-file within the Maven life cycle phase generate-sources.
However, the Ant-Build of Remote Tea is still supported and will at least get in charge
to create the release zip files, which will be continued to be uploaded to SourceForge.
Version 1.1.0:
This is a minor feature/maintenance release.
New features
Client-side
- The ONC/RPC client stub implementation has been extended by the method
nullproc() as a convenient way
to launch null procedure calls.
- The instance of an ONC/RPC client stub implementation can now be bound to other ONC/RPC client instances during
its lifetime via the method
setClient(). Besides, a previously used ONC/RPC client instance will be closed by
this method.
Server-side
- With this release custom authentication schemes can be defined and registered to an ONC/RPC
server stub.
jrpcgen
- jrpcgen considers and realizes the following new command line options on invocation:
-t
create TCP server only
-u
create UDP server only
-noxdr
do not create XDR datatype classes
Maintenance
Server-side
- Authentication failures such as bad credentials and bad verifier
within ONC/RPC authentication handling have not been reported back to clients, properly. Such authentication
failures lead now to an appropriate authentication failure reply to clients.
jrpcgen
- Consider the following quite legal definitions in an .x-file:
struct MyStructure {
int x;
int y;
};
typedef struct MyStructure MyStructure;
The typedef caused an error recognizing a duplicate identifier. Such a typedef is now
recognized and silently ignored.
Keep in mind that a typedef such as
typedef struct MyStructure TMyStructure;
still leads to the generation of the java class:
class TMyStructure {
public MyStructure value;
...
}
Version 1.0.7:
You already guessed it: minor update/maintenance release.
- Fixed inheriting character encoding from TCP-based listening server transport
to the child TCP-based server connection transports.
- Fixed/corrected behavior when registering server transports: an ONC/RPC exception
with the reason
OncRpcException.RPC_CANNOTREGISTER will now be thrown if the local portmapper
denies port registration.
Version 1.0.6:
This is again a minor update/maintenance release.
- Fixed encapsulation of properties when generating beans.
- Fixed miscalculation of remaining timeout, which could case
infinite timeouts.
Version 1.0.5:
This is a minor update/maintenance release.
- Fixed a code generation error in jrpcgen which cause the protocol
compiler to emit ONC/RPC server code that did not properly returned errors for
unsupported programs.
- Added new jrpcgen-test target to Ant build file so that the
jrpcgen protocol compiler can be more easily tested on the example files.
- Fixed
build.xml Ant script to include also exactly this
build file in the source code zip which gets uploaded to Source Forge.
Version 1.0.4:
It has been a long time since the previous release ... but yes, I finally
managed to pick up the patches sent and rolled them into the new release. Many
things changed in the meantime so I'm glad I got this release out of the door at
all. My new employer throws all kind of really interesting tasks at me, so
RemoteTea is now a really low profile project to me. If volunteers will step forward
to maintain RemoteTea I would be glad to welcome them aboard the RemoteTea
project.
- Added a new option
-bean to jrpcgen
for generating accessors (setters and getters)
for all elements in a structure. Option -bean also implies
-ser. This feature bases on a patch from Ralph Neff.
jrpcgen now also accepts .x files without a
program section. In this case no stub classes are generated, but
Java source code files for all structures, enums, et cetera are still
generated. This feature bases on a patch from Bialas Krzysztof.- Updated to new CPU runtime, see also the
CUP LALR Parser Generator in
Java Version 11 at TU Munich.
- Incorporated patches for: compile target in Ant build file, include Ant
task in
jrpcgen.jar.
- Thank you all who sent in patches!
Version 1.0.3:
This release marks my movement from the website of the good old
Chair of Process Control Engineering to Sourceforge. Since
Remote Tea
has now quite some users, it was time to put the
project on its own feet. Let's see where this will lead to.
- With my transition from JBuilder to Eclipse a little bit
of rearrangement of a few files was necessary. In particular, the
old JBuilder project files are gone down the bit bucket, so say
hello
to the new Eclipse project files. With the switch to
Eclipse we now have a free IDE for a free ONC/RPC
package – and if you use ClassPath and an appropriate VM, then
the whole thing is free.
- Updated documentation – but you will probably already
have noticed that from the new style of this and the other HTML
files.
- Yet another small correction to jrpcgen: it does not emit unnecessary import
statements anymore. This silences especially the
Eclipse
IDE, but also other smart asses
.
- It is now possible to optionally control the character
encoding used when (de-)serializing strings. The
OncRpcClient
class now has a pair of accessors
setCharacterEncoding(encoding) and
getCharacterEncoding(). Similiar, OncRpcServerStub
gives control over character encoding on the server side.
Version 1.0.2:
- Fixed a bug in jrpcgen, which
caused the automatically generated constructor in server stubs,
which accepts a port number, to ignore this port number.
- Also squashed a bug which caused problems when definitions
from enumerations where used as program numbers.
- Small
todo
work done, so that jrpcgen now emits more useful information in
the javadoc tags for remote procedure parameters and
results.
- Removed old and useless code from jrpcgen that has alread been commented out
for quite some time.
- Added new parameter -withcallinfo
to jrpcgen. When specified on the
command line, jrpcgen emits server
method stubs which contain always as their first parameter an
additional parameter holding information about the remote call
itself. This can be used, for instance, for authentication
purposes, et cetera. The parameter is always named
call$ and of type
OncRpcCallInformation.
- Added new parameter -noclamp to
jrpcgen. When -noclamp is specified on the command line, jrpcgen emits client method stubs which use
the version number specified when creating the client object at
runtime. When this option is not given, jrpcgen defaults to the current behavior and
uses the version number as specified in the x-file.
Version 1.0.1:
- Fixed a bug in jrpcgen, which
emitted wrong stub code when a remote function contained more than
one parameter: in this case, enumerations were not properly coerced
to integers (thanks to Michael Smith for pointing this out and at
the same time supplying the patch).
- Fixed another bug in jrpcgen,
which resulted in some (enumeration) constants not being
dumped.
Version 1.0.0:
- Tired of all the pre-1.0 releases in the past two years, I
finally decided to go straight to the official 1.0 release. The past
releases were primarily aiming at feature completeness to some
degree, while the real basic parts were quite stable (with few
improvements and bug fixes) over time. So, ... we have reached
1.0! ...and will probably soon get to 1.0.x, sigh.
- For XDR structs with tail references to themselves, jrpcgen now emits serialization and
deserialization code which uses an iteration loop instead of tail
recursion. The benefit of this is that the call stack usage is
considerably reduced. Of course, this optimization can only be
applied if the reference to the same type is the last
element of the structure.
- Corrected a race condition, which sometimes caused the
listening TCP thread in ONC/RPC servers to die with
NullPointerExceptions. Many thanks to Michael Smith for
hunting down this one. Classes concerned are
OncRpcTcpConnectionServerTransport,
OncRpcTcpServerTransport and
OncRpcUdpServerTransport.
- jrpcgen now exits the VM with
a non-zero return code in case it was called through its static
main and jrpcgen stumbled
on an error. This allows jrpcgen to be
used in classic make projects. The Apache Ant is not affected by
this behavior.
- Added an additional constructor to the classes
OncRpcTcpServerTransport and
OncRpcUdpServerTransport. It accepts now a local
binding address. The server socket is then bound only to this/these
local address(es). In addition, jrpcgen now emits source code for server
stubs with an additional constructor which accepts the additional
binding address.
Version 0.95.2:
- Small change in
OncRpcTcpSocketHelper.connect() to accept a negative
timeout that signals to use the particular implementation-specific
timeout value.
- Added new constructor to
OncRpcTcpClient,
which accepts a timeout parameter (in milliseconds) as its last
argument. This constructor can be used to limit the connection
attempt period and finally makes the timeout functionality available
which has been implemented in the 0.95.1 release. It is important
to note that the timeout specified as the parameter to the
constructor does not apply to later ONC/RPC calls. These are
controlled as usual through the existing timeout-related
accessors.
- Made
OncRpcPortmapClient a stand-alone class,
which is not derived from OncRpcUdpClient any
more. This now allows applications to contact the portmapper either
using UDP/IP or TCP/IP (HTTP not yet supported).
- Bumped up the versioning information in
OncRpcConstants (I had forgotten to do so for the
previous releases...).
Version 0.95.1:
After a long time (and a Ph.D. thesis on metamodelling for
communication in operational process control engineering now written
and on its way) I've finally managed to get a new RemoteTea release
out of the door.
- Implemented timeout-controlled connects for TCP-based
ONC/RPC clients. The whole thing is a little bit tricky in view of
pre-1.4 JREs. However, I definitely want to support
JDK 1.2 and 1.3 (so much for write once, forget
everywhere).
The socket helper object features a connect method
which can execute timeout-controlled connection establishment. In
case the current VM Remote Tea is running on does not provide a
proper implementation, Remote Tea resorts to the following
algorithm:
- The
connect method creates a new thread
which in turn tries to connect to the given port at the given host
(an instance of the local class Connectiator is
responsible for this).
- The original thread initiating the Connectiator thread
now waits for it to finish, but no longer than the timeout
specified in the call to the
connect method. In case
the Connectiator does not succeed within the timeout period, an
IOException is thrown by the connect
method.
- The Connectiator object will signal itself in case it
succeeded, but also if it failed. Its
getIOException
method then either returns null or an
IOException.
- Fixed deserializing bug in
XdrDecodingStream.xdrDecodeLong(), where unwanted sign
extension messed up 64 bit wide integers (XDR hypers).
- Fixed a long-standing
feature
in
XdrTcpDecodingStream.fill(), which caused invalid
header decoding if the fragment length was larger than
227.
- Fixed sanity checks for those ONC/RPC partners sending
empty XDR fragments as last fragments of XDR records – a trailing
last XDR fragment that carries no data is now accepted. The fix
concerns the class
XdrTcpDecodingStream semantics of
the fill method were slightly changed to return also in
case of empty trailing record (lastFragment attribute
must be true). All methods directly calling
fill have been adapted (at least I hope
so).
- Improved handling of wrong or mismatching ONC/RPC messages
for UDP-based ONC/RPC clients. They do not emit new calls any more
when receiving replies from wrong sources and keep quiet instead
until the timeout expires (as per current timeout
strategy).
- Fixed some buffer offset bugs (forgot to take care of CRLF
at one place) in
XdrHttpDecodingStream, for which
patches were kindly offered by the austrian internet
chamoises.
- Added Ant task for jrpcgen as
org.acplt.oncrpc.ant.JrpcgenTask, kindly provided by
Jean-Francois Daune. This also involved some small changes to jrpcgen in order to make it available as a
task.
Version 0.94.2:
- Fixed bug in jrpcgen, which
caused a crash when hashing a union's structure (needed to create
serial version UIDs) and the union contained a non-empty default
arm. Also added appropriate
test case
to demo.x.
Version 0.94.1:
- Added two new code generation options to jrpcgen:
- -ser: tag classes generated for
XDR structs, XDR unions and XDR typedefs as serializable. Also
automatically generates
serialVersionUID using the
SHA-1 algorithm. (My thanks to the GNU classpath project for
providing the SHA-1 algorithm, please see
Jrpcgen.SHA.java for license details).
- -initstrings: automatically
initialize all
Strings as empty strings (""). Note
that this may lead to lazy programming; better make explicitly
sure that every member of a struct gets initialized properly
before encoding the struct.
Version 0.93.1:
- Once more fixed support for JDK 1.1 for Java-based
ONC/RPC servers: the old code still used a LinkedList, which is only
available since JDK 1.2. So I added a minimalist double linked
list local class (it's in
OncRpcTcpServerTransport.TransportList).
- Worked around some broken JDKs 1.1 (especially on
AIX, but I have also heard of problems on Linux), which have broken
InetAddress.getLocalHost. The code now uses
InetAdress.getByName("127.0.0.1"). Yeah, write once,
does not work anywhere.
- Added overloaded
client.call method which
expects an additional (procedure/protocol) version number as its
second argument. This method is necessary so several versions can
coexists peacefully in one client and can be called
simultaneously. As before, if you do not specify a version in the
call to client.call the default
version is used
as specified in the constructor. Please note that
OncRpcClient-derived classes must now implement the
overloaded call method expecting four parameters:
procedure number, version number, parameters, and result (this only
applies to those who want to implement their own ONC/RPC clients for
different transports than those already provided).
- Added support for multiple parameters in procedure
declarations within x-files, to be more in sync with newer rpcgen
releases. In addition, jrpcgen now also
accept named parameters in remote procedure declarations. Both
enhancements caused quite some changes in the code emitting parts of
jrpcgen: local wrapper classes are used
to serialize and deserialize multiple parameters.
Version 0.92.1:
- Support for batched ONC/RPC calls when using TCP-based
transports: see OncRpcTcpClient.batchCall() for more
information.
- Added support for handling multiple ONC/RPC programs
and/or versions through the same server transport.
- jrpcgen now emits a second
constructor expecting the port number to bind transports to as its
solely parameter. This allows server writers to bind their servers
to well-known ports.
- Added a jportmap and an embedded portmap
service class. It can be used by standalone applications which
should also be useable if the user has not installed a portmap
service. I must have been bored or insane. Or both.
- Made several
OncRpcServerStub methods public
(instead of protected), to give derived server classes more control
over the way they spin up and down.
Version 0.91.2:
- Ashes on my head for releasing 0.91.1 with a really dumb
bug related to JDK 1.1 backwards compatibility which broke JDK2
compatibility completely. When using reflection one can not call
the superclass' methods for obvious reasons, so an endless recursion
occured in
OncRpcTcpSocket. So much for almost not
testing the release. To fix this stupid design bug the classes
OncRpcTcpSocket and OncRpcUdpSocket were
moved to OncRpcTcpSocketHelper and
OncRpcUdpSocketHelper. They now merely support
Socket and DatagramSocket instead of
inheriting from them. This avoids the endless reflection method
invocation loop, but is still cheaper in terms of method invocation
performance than a wrapper class.
- Fixed missing JDK 1.1
compatibility for the server classes.
Version 0.91.1:
- Fixed a deserialization bug with
AUTH_NONE on
the server side in OncRpcServerAuth.xdrNew when
recycling the AUTH_NONE handler singleton.
- Removed automatic startup from the constructor of jrpcgen generated server stubs. The
constructor of a server stub class now only creates the transport
objects and sets the public
transports field within
class OncRpcServerStub. Registering with the portmapper
as well as dispatching calls is now done within the
run() method (note: without any parameters). You need
to change your code accordingly by inserting a call to
run(), otherwise the server will not start.
MyServer myserver = new MyServer();
myserver.run();
- Preparations for cvs check-in: in order to handle
individual Java projects in form of cvs submodules within the
toplevel cvs module
java
, some files were moved. The JBuilder
project files have been moved to the projects/
subdirectory.
- Fixed problem with jrpcgen
emitting constants which depend on other constants in wrong
order. Constants which are needed by other constant definitions are
now emitted first. In case an enumeration element depends on a
global constant (or for some reason on another enumeration element),
then the enclosure is taken into account too. The
demo.x example now tests some pathological
cases.
- Added backward support for JDK 1.1. While I'm not
very proud of it, many people requested this as quite some companies
use the bug-ridden MS InternetExploder with its very own
JVM. Changes include using
addElement instead of
add when adding objects to a
Vector.
- Moved the readme documentation into its own directory
readme-first/ which should be more obvious to
first-time users of the RemoteTea source code and does not clobber
the projects/ directory any more.
- Fixed
NullPointerException in
OncRpcTcpClient and OncRpcUdpClient when
checking for rejected credentials – and I thought Java had no
pointers.
- jrpcgen: support for short
form
unsigned in addition to unsigned int
(compatibility with rpcgen). Handling of octal numbers
added (okay, it is still a valid number format). Fixed bug in the
code generation of desciminated unions using booleans. Support for
more than one program definition within the same x-file. In this
case the source code files generated for the client and server stubs
are named
<x-filename><program-id>Client.java
and
<x-filename><program-id>Server.java,
respectively.
- First rough cut for tunneling ONC/RPC client calls through
HTTP connections. On the other end, you will need the
Tea
Tunnel
Apache DSO module, which untunnels
calls and
forwards them to the appropriate ONC/RPC server using direct TCP/IP
or UDP/IP connections (or non-connections in the case of
UDP/IP).
- Added new package
org.acplt.oncrpc.web
containing helper classes for HTTP client connections
(HttpClientConnection), and base64 encoding and
decoding (Base64), as well as some other
stuff.
- Added new class
OncRpcHttpClient, which
stands in the tradition of OncRpcClient and implements
sending ONC/RPC calls through HTTP tunnels. Also added
XdrHttpDecodingStream, which can pull base64 encoded
data from a web server and provide the decoded data through the
usual decoding XDR stream interface.
Version 0.90.1:
- Fixed
XdrEncodingStream.xdrEncodeByteFixedVector() which
falsely encoded length information about the following array of
characters. I should take more care when doing Italian code
recycling using copy & pasta...
- Fixed bug in
OncRpcTcpClient.call() which
caused XDR buffer underflows when receiving the next reply after the
previous reply has been rejected by an ONC/RPC server.
- Updated package.html for package
org.acplt.oncrpc to put it in sync with (de-)
serializing fixed-size vectors and dynamic and fixed vectors of
characters.
- Added
AUTH_UNIX authentication. For this to
achieve quite some additions and changes were necessary –
luckily, old applications will not be broken, as the changes are
deep within the RemoteTea package:
- See OncRpcClient for a description about how to use
authentication with ONC/RPC clients.
- For handling of client-side authentication issues, the
classes
OncRpcClientAuth,
OncRpcClientAuthNone and
OncRpcClientAuthUnix were added.
- The ONC/RPC call and reply message classes
OncRpcReplyMessage and OncRpcCallMessage
are now both abstract. This was necessary because ONC/RPC protocol
issues make it necessary to handle authentication through
so-called authentication protocol handling objects different on
the client side than on the server side. Additional classes now
handle sending calls and receiving replies on the client side
(OncRpcClientCallMessage and
OncRpcClientReplyMessage respectively), as well as on
the server side (OncRpcServerCallMessage and
OncRpcServerReplyMessage). According to their needs,
these new classes only declare those encoding and decoding methods
which are really needed. In consequence, the base class
OncRpcCallMessage has lost its XdrAble
interface completely.
- Added authentication handling and credential refreshing
to
OncRpcUdpClient and OncRpcTcpClient,
as well as to the base class
OncRpcClient.
- Added authentication protocol handling to ONC/RPC
transports. If servers want to take advantage of authentication,
they need to look at the
callMessage.auth attribute
of the OncRpcCallInformation delivered with each
incomming ONC/RPC call. See
tests.org.acplt.oncrpc.ServerTest.java for an
example.
Please note that AUTH_DES is still not supported, as
this needs quite some things to be done and I don't have full
information about the AUTH_DES protocol.
- Added new classes
XdrBufferEncodingStream and
XdrBufferDecodingStream for encoding and decoding XDR
data from and to a fixed-size buffer. These classes comes in handy
when dealing with shorthand credentials.
- Added class
XdrDynamicOpaque to handle
variable-sized vectors of bytes.
- Moved the jrpcgen package to
org.acplt.oncrpc.apps.jrpcgen, because it's an
application belonging very tight to ONC/RPC.
- Added new
OncRpcConstants.REMOTETEA_VERSION_PREVERSION, which
indicates preversions if not zero.
Version 0.86.1:
- As Sun's rpcgen encodes
char<> as a
series of characters, each one sitting happily in its very own XDR
int (that is, four bytes), the two methods
XdrDecodingStream.xdrDecodeBytes() and
XdrEncodingStream.xdrEncodeBytes() were renamed to
XdrDecodingStream.xdrDecodeByteVector() and
XdrEncodingStream.xdrEncodeByteVector() as well as
their semantics changed accordingly.
- Added methods
XdrDecodingStream.xdrDecodeDynamicOpaque(),
XdrEncodingStream.xdrEncodeDynamicOpaque(),
XdrDecodingStream.xdrDecodeByteFixedVector() and
XdrEncodingStream.xdrEncodeByteFixedVector().
- Fixed jrpcgen accordingly, so
it generates proper code for arrays of bytes and opaque data types
accordingly.
- Made all non-abstract encoding and decoding methods in
XdrDecodingStream and XdrEncodingStream
finally final. Maybe this helps Java compilers improve
code speed. Maybe.
- Fixed jrpcgen code generation
error when the size of an array was specified using a constant
identifier. Now jrpcgen properly
references the constant from the x-file's main class.
- Fixed some documentation errors for
XdrDecodingStream and
XdrEncodingStream.
Version 0.85.1:
- Added new method
readBuffer() to class
XdrTcpDecodingStream. This fixes problems when reading
from a TCP/IP stream and not all bytes wanted are immediately
available, thus stream.read() returning not all bytes
at once (shame on me for not reading the java.io documentation
attentive enough).
Version 0.84.1:
- Added control over the retransmission strategy used by
UDP/IP-based ONC/RPC clients. The default strategy is now not to
resend lost ONC/RPC calls (retransmission timeout is set to the
overall timeout). Either a fixed retransmission timeout can be
choosen, where lost calls are resend every <retransmission
timeout> milliseconds, or an exponential back-off alogorithm. The
exponential scheme starts with the retransmission timeout and
doubles it every time a call is lost, until the overall timeout is
reached.
- Added two more constructors to ONC/RPC clients generated
by jrpcgen from x-files. These
constructors now also accept the remote program number, so
application writers gain full control.
Version 0.83.1:
- Fixed support for indirection in decriminated unions. Also
cleaned up some minor things related to constants and
enumerations. Thanks to Ulrik Sandberg for throwing all kinds of
vicious x-files at jrpcgen.
Version 0.82.1:
- Added support for indirection in x-files, also called
optional data
in ONC/RPC babble. Also added a new test case
to the demo.x file.
Version 0.81.1:
- Added broadcasting of ONC/RPC calls to UDP/IP-based
ONC/RPC clients through the new
broadcastCall of method
in class OncRpcUdpClient.
- Added helper methods for encoding and decoding fixed-size
vectors for various base data types.
- Added a description about mapping rpcgen (RFC 1832)
data types to Java data type.
- Added an RPC protocol compiler named jrpcgen. Sun's documentation on the rpcgen
syntax and grammar is rather thin and sometimes inaccurate. As
always, I had to resort to RTSL (
Read The Source, Luke!
) to
find out what syntax and grammar rpcgen does in fact use. Please
give it a try and report problems. Note that there is no
preprocessor step.
Version 0.80.2:
- Fixed a buffer underflow exception in XdrUdpDecodingStream
in methods
xdrDecodeOpaque(int) and
xdrDecodeOpaque(byte[],int,int). This cures the bug
where a XDR string being the last piece of information in a RPC call
or reply could not be read successfully.
- Added
org.acplt.oncrpc.OncRpcConstants, which
contains versioning information.
Version 0.80.1:
- Separated the ONC/RPC package under the name
Remote
Tea
from the ACPLTea package. As the ONC/RPC implementation is
pretty functional the version number was changed to reflect
this.
- Added XDR primitive and serializable data types for
strings, floats, etc.
Version 0.35.1 and before:
- Graciously hidden in the mist of history (probably also in
the midst of history). The Remote Tea package was then only
