Title

Integrate expat parser into Axis2/C soap engine

ASF Project

Apache Axis2/C

Keywords

Apache Axis2/C, expat, xml, soap

Description

Apache Axis2/C is a soap processing engine written in C. Any xml parser could be pluggable to Axis2/C engine through a parser abstraction layer, already we have integrated two xml parsers to Axis2/C engine namly libxml2 and Guththila xml parser. This is an idea to integrate expat parser to Apache Axis2/C through parser abstraction layer. If you need more information please come and ask on axis-c-dev@ws.apache.org

Description

Apache Axis2/C is a soap processing engine written in C. Neethi is its ws-Policy supporting module. Current implementation does not have support to policy intersection. And it does not support operation and message level policy support at client side. And domain specific policy processing are not distributed to those domains (eg : security). This project includes adding those improvements to Neethi/C.

Description

Axiom/C currently doesn't support XPath language. It would be an advantage to have an XPath implementation, when WS-Trust and other WS-Security related specifications are concerned (Which are being implemented in Rampart/C, a sister project of Axis2/C). This project is to implement XPath Language 1.0 or 2.0 or both specifications on Axiom/C. If you are interested, axis-c-dev@ws.apache.org would be a good place to direct all your questions.

DRLVM uses inconsistent APIs for native memory management, such as APR or malloc or mmap. It is desirable to have a unified API for native memory management. Hopefully the runtime native memory usage can be managed with a global view and then optimized. This layer could be extended to provide the API for Java heap native management as well.

One may notice a lack of open source effective parallel GC implementation for C/C++ programs. For example, Parrot (Perl 6) community expressed an interest in attaching our GC to their code base. If numbers would show some benefit, we might get other adopters of our code base. Successful completion of GC library on the top of Harmony would teach a person in refactoring skills and give a good background in garbage collection.

Description

Support the invokedynamic instruction i.e. the ideas of JSR 292 draft. And implement basic support for a dynamic language like Python, Ruby, JavaScript as a proof of concept. We want this language to have dynamic typing, reasonable user base, usable standard library, a set of compatibility tests. Students are free to choose the actual dynamic language. We will discuss the reasoning behind the choice. The code involved is C (VM part) C++ (JIT) and probably some class library part in Java. The task is rather challenging for the summer, hence, will require a lot of interaction with the team on the tricky details. Lots of fun guaranteed.

Refactor Java Bytecode Translator in Harmony JIT

ASF Project

Apache Harmony http://harmony.apache.org

Keywords

C++, JIT, bytecode, compilers, Java

Description

The optimizing JIT (Jitrino.OPT) parses Java bytecode on early stages of method compilation to produce Internal Representation to allow further stages to optimize it. This code is well-tested, but not easy to extend (for example, not easy to teach JIT to understand new types of instructions) The major inconvenience is that translator makes things too complicated by trying to optimize on the fly. The task is to refactor the Java-Bytecode-Translator in the Jitrino.OPT to make the code cleaner and simplify the data structures used. Move optimization to a separate stage. Take care of correctly mapping line number info from bytecode into JIT instructions. Code is C++, but not a tricky style. The student will get an in-depth knowledge of Java bytecode, overall knowledge of just-in-time compilation techniques.

An SCA implementation extension for Erlang

ASF Project

Apache Tuscany http://incubator.apache.org/tuscany/

Keywords

Apache Tuscany, Erlang, SCA

Description

One for the programming language geeks: develop a Tuscany implementation extension for Erlang. SCA and Apache Tuscany define a next generation programming model with extensible support for any programming language. In this project you would create a Tuscany extension for Erlang, one of the more interesting languages of recent times. Dennis Byrne has written an article on integrating Java and Erlang so that along with the code for one of the existing Tuscany language extensions gives a good start for getting a Tuscany Erlang extension working, although the nature of Erlang does make this a little more challenging than a regular Java extension.

Description

That GSoC project could explore a few interesting options, including: Use SCA to model references from Javascript gadgets to server-side services, and provide transparent access to these services (by injecting Javascript proxies into the gadgets, similar to what Tuscany currently does with its SCA Widget component support). Use SCA composites to configure and assemble the gadgets together as well, allowing the application developer to use a consistent SCA-based assembly model for client-side mashups, server-side compositions and mixes of the two..

Title

Integrate Java SCA with PHP

ASF Project

Keywords

PHP, PECL, SCA

Description

PHP PECL project provides a PHP implementation of the Service Component Architecture (SCA) programming model (see http://pecl.php.net/package/SCA_SDO). SCA is a programming model which allows you to assemble applications using a Service-Oriented Architecture style. This includes producing and consuming Web services of various types, including soap/http, json-rpc, REST,Atom. Looking into the Tuscany Apache Incubator project (see http://incubator.apache.org/tuscany/ ), which provides a Java-based implementation of SCA. This runtime is extensible for different implementation types, and currently supports things like BPEL, OSGi, Java (POJOs), Spring, JavaScript and XQuery. <br> I think it would make a very interesting and challenging project to extend Apache Tuscany to supports the concept of a PHP implementation type. This implementation type would be used to include PHP SCA enabled applications in an assembly which might also include any of the other Apache Tuscany implementation types. A realistic scenario for this solution might be a PHP Web front end to a Java business application. Tuscany includes a Java "store" application which could be converted to demonstrate the final deliverables. The solution would also require extensions to the PHP SCA project to enable existing PHP SCA service configuration to be externally overridden by Tuscany. The major work items would be as follows: <br><br> 1. Extend PHP SCA to support external configuration of services (PHP Scripting skills).<br> 2. Extend Apache Tuscany to provide a PHP implementation type (Java and XML/XML Schema skills).<br>3. Extend Apache Tuscany to support PHP SCA as a deployment target(Java skills).

Verp Bounce handler

ASF Project

Keywords

java, email, verp, mailing list

Description

Variable Envelope Return Path (VERP) http://cr.yp.to/proto/verp.txt is an elegant technique for identifying the original message or recipient associated with a "bounced" email. It requires two components an outbound re-writer to modify return addresses of outbound email, and an inbound handler which identifes the failed recipient or message and passes this on to a component which can "do something useful". Apache James has an extensible architecture using plug-ins called Mailets which is ideally suited to the development of enhancements such as these.

Description

Apache Rampart is the security module of Axis2. It secures SOAP messages according to specifications in the WS-Security stack. Rampart currently doesn't store the auditing details about SOAP messages.It will be very useful for system administrators to have the auditing details about successful and failed attempts and other useful information as set of audit logs/reports. These logs should be secured yet should be very easy to be monitored by administrators. Apache Rampart should also be improved to use these information when necessary to validate the security for incoming messages.

Add OpenID support to Roller both for user accounts and for those leaving blog comments. Make it so that new and existing users can choose to tie their user account to an OpenID identity and use that for all subsequent logins. And, make it so that bloggers can require that folks login via OpenID before leaving a comment. These features could be implemented by modifying Roller's existing Spring Acegi configuration and/or by documenting how to use a Container Manager Authentication (CMA) configuration, e.g. OpenSSO paired with a Servlet Container. Either way, it is likely that you'll have to write some custom Java code to make this work.

Description

By accessing Roller's existing AtomPub interface you can get all of your blog entries and all of your file uploads, but how do you get the rest of your blog data out of Roller? If you exposed all Roller data via AtomPub collections, you could make it very easy for folks to extract their data from Roller. You would need to support new Atom collections for comments, bookmarks, templates, categories and weblog settings. And, you'd need to define some Atom format extensions to hold some Roller specific setting (blog entry plugins, comment rules, etc.). Develop something good enough and you could get other blog vendors to support it too; you could solve the whole blog data portability problem once and for all! You can choose to use Roller's existing ROME AtomPub implementation or develop a new one with Abdera (see also roller-abdera).

Thereis no way to page through your file uploads, you can't search, you can't see thumbnail images, the folder creation user interface is poor and you can't store any metadata for each file. Once you've uploaded an image, there is no "Would you like to resize and blog that image?" or any other help with using images. What we need is a whole new interface in Roller for uploading, browsing, searching and using uploaded files. You can design this new interface and even pick a (Apache-license compatible) JavaScript library to help you, but on the server-side you must implement via Roller's Struts 2 action infrastructure.

In a nutshell an XML Schema author will define an assocication between a condition, in the form of an XPath expression, and a type. When the condition is met, the associated type will be used as the element's type. The goal of this project is to design and implement the Conditional Type Assignment in Xerces-J.
