PHP_Depend-0.9.3 released

Just now I released PHP_Depend 0.9.3, the primary goal for this release was focused on less memory consumption. A run of PHP_Depend 0.9.2 against eZ Publish took up to 1GB and PHP_Depend 0.9.3 analyzes the same source with a memory limit of 160Mb.

Fixed #89: The source file is never set for methods, properties and constants.
Closed #82: Tokenizer cache added, reduces runtime up to 25%.
Closed #83: Storage layer for node tokens added, reduces memory consumption. .
Closed #85: TextUI displays the execution time and the memory usage(linux only).
Code restructured, input filters and iterator moved to package "Input".
Test suite restructured to reflect the actual project structure.

From now on you will get the latest PHP_Depend version through the new pear channel pear.pdepend.org, for a few weeks I will keep the old pear channel. Enter the following pear commands to upgrade PHP_Depend's channel.

mapi@arwen ~ $ pear channel-discover pear.pdepend.org
mapi@arwen ~ $ pear uninstall xplib/PHP_Depend
mapi@arwen ~ $ pear install pdepend/PHP_Depend

Or checkout version 0.9.3 from the PHP_Depend subversion repository.

mapi@arwen ~ $ svn co http://svn.pdepend.org/tags/0.9.3

Hi,

Why in
PHP_Depend_Metrics_ClassLevel_Analyzer::visitMethod()
You sum all ccn2 to compute CIS ?

$this->_nodeMetrics[$uuid]['cis'] += $ccn2;

The definition :
CIS Class interface size Number of non-private methods + variables defined by class. CIS = WMCnp + VARSnp. Measures the size of the interface from other parts of the system to the class.

I understand WMCnp in pdepend it's not 1 per method but ccn2.
In this case there is a metric giving the number of public methods and variables of a class ?

Hello Davide,

you are right, the WMC and CIS metrics use a variant of thew original metric definition, described in an IEEE paper.

It is interesting that you ask me today for a metric that sums all public members of a class, because I needed the same information this morning, which isn't provided by one of the currently available analyzers, but I will add it to one of the next PHP_Depend versions...

Greetings
Manuel
