Userland database driver implementations

Following a discussion we had about software packaging for our test, qa and live clusters (most of which run Debian Lenny, meaning it brings PHP 5.2.6 with the mssql extension, unfortunately unsuitable for ASE 15 / univarchar fields), we decided two things:

1. We need to compile a more recent PHP version with sybase_ct ourselves
2. We should investigate in more independence from installed system libraries and PHP extensions

5.7.10-RELEASE: Independence day!

The XP group is proud to announce the availabality of XP Framework, release 5.7.10. The highlights in this release include support for unbuffered queries, changes to the unittest runner to also fail for tests with @expect when warnings have occurred, logging of all exceptions in webservices, a nicer string representation of XML trees, support for mysqli and mssql extensions as snap-ins when mysql or sybase_ct are not available, respectively, and various improvements to the web runners.

5.7.10-RELEASE RC3

This third release candidate includes support for PHP's mysqli (MySQL Improved) extension as well as the new Tree::withRoot() method completing the xml API's fluent interface.

To give this release a test run, install it as always:

  $ cd ~/xp
  $ wget http://releases.xp-framework.net/setup/5.7.10RC3 -O - | php -- -d ~/bin/

Fluent XML with the XP Framework

To create an XML tree programmatically, the XP Framework has offered the xml.Tree class since its beginning in 2001. Recently, we've added a fluent interface to it, allowing for the following:

<?php 
  $t= create(new Tree())->withRoot(create(new Node('book'))
    ->withChild(new Node('author', 'Timm'))
    ->withChild(new Node('isbn', '978-0000000000'))
    ->withChild(new Node('title', 'Fluent XML with the XP Framework'))
  );
?>

5.7.10-RELEASE RC2

This second release candidate includes support for unbuffered queries (RFC #0203) and fixes to the JSON de-serialization mechanism for numbers larger than LONG_MAX (or smaller than LONG_MIN).

To give this release a test run, install it as always:

  $ cd ~/xp
  $ wget http://releases.xp-framework.net/setup/5.7.10RC2 -O - | php -- -d ~/bin/

Web runner refactoring release

The web runner infrastructure was refactored for better testability.

These refactorings included changes to the URL mapping. Consider the following (abbreviated) example:

  [app]
  map.service="/service"
  map.all="/"
  
  ...

  $ cd ~/xp
  $ wget http://releases.xp-framework.net/setup/5.7.10RC1 -O - | php -- -d ~/bin/

RFC #0203: Unbuffered queries

Scope of Change
Unbuffered queries will be supported by a dedicated API. Instead of using rdbms.DBConnection::query() (or any of the insert, update, delete or select methods), the result-only rdbms.DBConnection::open() method will support unbuffered queries.

Rationale
Incremental row processing to save memory.

5.7.9-RELEASE: Class loader refactoring

The XP group is proud to announce the availabality of XP Framework, release 5.7.9. The highlights in this release include the class loader API refactoring, introducing new distinguishable exceptions for errors during class loading, STOMP support and the implementation of RFC #0201 and thus an easy way to "patch" the XP Framework.

RFC #0201: XP Overlays

Scope of Change
Path files will support prepending elements to the class path via special syntax.

Rationale
Sometimes it's necessary to overwrite certain parts of the XP framework's classes (the ones distributed in xp-rt xar files). One of the usecases is to keep using deprecated APIs in conjunction with a release in which they were removed, but being able to use new APIs provided with this release in other parts of the program. Another example is the ability to production- test new functionality (e.g., from SVN head, or even from the experiments in xp forge) together with the latest release.

RFC #0200: XML API Rework

Scope of Change
The XML API will be extended to fully support markup-style XML documents.

Rationale
At the moment, certain information will be lost when loading and then emitting an XML tree:
