Re: [phpCallGraph-general] dummyFunctionForFile_filename_php() ?

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

Hi Martin,

yes, it means that the code to be analyzed has to be altered.
An example for a file called test.php would be:

<?php
function dummyFunctionForFile_test_php() {
    phpinfo();
}
?>

Of course this is not very elegant, but currently the only
feasible way due to some conceptual restrictions resulting from the
utilization of the InstantSVC CodeAnalyzer. I already had an idea on how to
make that dirty dummy function workaround unnecessary, but it's like
always: So much to code, so little time. ;)

btw: Are you analysing any free software? I'm always keen to put interesting
examples on the phpCallGraph website.

Cheers,
Falko

Re: [phpCallGraph-general] Doesn't always get caller class correct?

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

Hi Martin,

first of all, thank you for this awesome contribution!

It is a known issue of phpCallGraph that certain cases are not analyzed
correctly by the currently applied heuristics. I'm currently investigating
possibilities of symbolic execution to get these calls right. However, it will
still take a while until this issue will be solved.

If you need the source code of the function/method, you can extend the signature
of CallgraphDriver::startFunction to include either the line numer of the end of
the function or directly the source code. Both are available when this method is
called in PHPCallGraph::parseMethodBody. Of course, you would have to change all
implementations of the CallgraphDriver interface, but that shouldn't be to hard,
since they could just ignore the additional data.

I wasn't able to actually get output from your driver. Or more specifically the
PNG and HTML output files where empty. I guess, this is due to some external
software missing on my machine. Could you therefore add some hints on how to use
your driver to the readme.txt?

Re: [phpCallGraph-general] Doesn't always get caller class correct?

[<Ma...@Cl...>]

To be clearer, here's a real example:

Most of the call arrows for the attached are correct, except for the
following two, where the class is unset, meaning my code draws the
arrows to :ClassUnknown:

        $ca->inspectFiles($files);
        $this->codeSummary = $ca->getCodeSummary();

Thanks,
    Martin.

<?php
class PHPCallGraph {
    public function parse(array $filesOrDirs, $recursive = false) {
        $files = $this->collectFileNames($filesOrDirs, $recursive);
        $ca = new iscCodeAnalyzer(null);
        $ca->setDebug($this->debug);
        $ca->setAutoloadFile($this->autoloadFile);
        $ca->inspectFiles($files);
        $this->codeSummary = $ca->getCodeSummary();
        $this->analyseCodeSummary();
    }
}
?>

Sorry about that incomplete email - I was balancing my 8 month old on my lap!

This is what it should have said:

> It works quite well but doesn't seem to always be passed a class, leading the call arrows to go to UnknownClass rather than to the correct object.

More examples can be seen in

>Is the class=null on addCall() a known issue?

Also, I want to be able to get the source code of the current method
available to the driver. Can we make the codeAnalyzer available to the
driver, or pass the sourcecode?

Thanks,
   Martin.

Re: [phpCallGraph-general] Can't check out the SVN source tree

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

Hi Martin,

I just tried a fresh checkout with your commandline and had no problems. You
should only obtain the trunk:
svn co
https://phpcallgraph.svn.sourceforge.net/svnroot/phpcallgraph/trunk phpcallgraph

Otherwise you get way too much stuff, i.e., all versions that have ever been
released, the website with it's example collection and some experimental branches.

Hope that helps.

Greetings from Berlin,
Falko

[phpCallGraph-general] dummyFunctionForFile_filename_php() ?

[<Ma...@Cl...>]

Fakko,

You write:

"Such code can be manually wrapped in    a dummy function called
dummyFunctionForFile_filename_php() which will then
    be recognized by PHPCallGraph."

Can you give me an example of this? Do I have to alter the source code being
analyzed?

Looks really interesting this, I'm looking to see if I can generate a UML
sequence diagram from the call graph.

Thanks,
   Martin.

Sorry for the late response. It took me a while to get my hands on a Windows box
in order reproduce and fix the issue.

I just released a patched version of phpCallGraph 0.7.0 which can be downloaded
at: http://downloads.sourceforge.net/phpcallgraph/phpcallgraph-0.7.0-pl1.zip

[PHPCallGraph-general] phpCallGraph 0.7.0 released

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

Hi,

Version 0.7.0 of phpCallGraph has been released. Most importantly, it fixes a
severe bug, which prevented correct recursion into sub-directories. Furthermore,
it features support for autoloading, a debug option for finding analysis
problems, as well as new colors and fonts for better readability.

The sandbox of the InstantSVC CodeAnalyzer has also been greatly improved by
introducing white-list-based function call filtering. This allows for performing
source code analyses using reflection without the danger of accidentally
executing code in the global scope.

All users are encouraged to upgrade to the new version, which can be downloaded
at http://phpcallgraph.sourceforge.net

Best regards,
Falko

[PHPCallGraph-general] New version of PHPCallGraph with analysis of functions and global scope

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

Hi everyone,

I used some spare time at the 24C3 to compile a new release of PHPCallGraph.
While PHPCallGraph was initially developed for object-oriented code,
this release adds the ability to analyze user-defined functions.

Also code in the global scope (outside any functions or methods) can now be
analyzed with the help of a little workaround: Such code can be manually wrapped
in a dummy function called dummyFunctionForFile_filename_php() which will then
be recognized by PHPCallGraph.

Of course this is not very elegant but currently the only feasible way due to
some conceptual restrictions resulting from the utilization of the InstantSVC
CodeAnalyzer.

Download PHPCallGraph v0.6.4 at http://phpcallgraph.sourceforge.net

Happy New Year!
Falko
