[phpCallGraph-general] phpCallGraph 0.8.0 released with UML Sequence Diagram Generation

[Falko M. <ma...@fa...>]

Hi,

It's been a while since the last release of phpCallGraph and in the meantime a
couple of new developers joined to the project. Thus, version 0.8.0 introduces
several new features and improvements.

Most notably, Martin Cleaver added the ability to generate rudimentary
per-method call graphs in the style of UML sequence diagrams. The new
UmlGraphSequenceDiagramDriver outputs scripts readable by UMLGraph
(http://www.umlgraph.org), which are then used to generate images with pic2plot
of the GNU plotutils package. These images represent the calls made by a
particular method.

Another change, which might be a bit of a surprise for users of previous
versions, is the change of the layouting direction in the GraphVizDriver from
top-to-bottom to left-to-right. Experience has shown that this allows for more
compact call graph layouts.

Till Klampaeckel developed an output driver that outputs the calls as a
serialized associative array. This allows to use the collected data in other
PHP-based tools.

Further improvements are a dead (unreachable) code analysis, new debugging
facilities and a first approach to symbolic execution, which allows for tracking
variable types. A newly introduced unit test suite allowed for some refactoring
and the switch to updated versions of the underlying libraries without breaking
things. This will also pave the path for further improvements of the analysis
algorithms and the symbolic execution.

Thanks to Christian Weiske and Till Klampaeckel we will soon provide PEAR
packages for phpCallGraph and its underlying libraries.

All users are encouraged to upgrade to the new version, which can be downloaded
