[phpCallGraph-general] Updated version of phpCallGraph

[Seb35 <se...@se...>]

Hello,

I was interested in obtaining the call graph for one of my software, and 
found phpCallGraph. I got issues running it with PHP 5.6/7.0, so I fixed 
the major bugs I encountered.

The resulting patched phpCallGraph is on my GitHub account [1], with the 
last versions of ezcomponents, CodeAnalyzer, and PEAR librairies. When 
running it, the major issues I still have are related to autoloading 
classes.

I successfully ran it on:
* src/PHPCallgraph.php
* my MediaWiki extension [2]
* some other MediaWiki extensions or packages [3]

I plan to improve the quality of phpCallGraph, apart if there is another 
more recent call graph creator for PHP I’m not aware of:
* fixing major bugs: autoloading (e.g. Composer autoloader), missing 
indices in arrays
* in the longer term, improve the inner quality:
   * I was surprised because ezReflection does not add a lot of features 
compared to the standard (today’s) Reflection and it is responsible of 
quite a lot of warnings/fatal errors,
   * perhaps use some phpDocumentor Reflection packages (Reflection [4], 
TypeResolver [5]) if they prove to be good quality,
* in parallel, given the huge graphs it creates for huge packages like 
MediaWiki, I had the idea of creating a visualisation with D3.js to dive 
into the call graph with various zoom levels, perhaps linking the call 
graph of a plugin/extension to a high-level graph of the underlying 
software, displaying only relevant parts of it (exceptions, router, 
global functions, hooks); just an idea to be better defined and improved.

This tells you that ezcReflection-0.7.0 was used, which was not
released at the time. I have no idea if that was ever released, my temp
file is not available anymore.

I guess that graphviz is not compatible with the version of ezc
components that you installed.

Unfortunately I don't know which is the latest version that worked.

Re: [phpCallGraph-general] Sub-Class is not shown on graph

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

Hi osa2,

you can use the --autoload option to provide a file with an autoload 
function.

[phpCallGraph-general] Sub-Class is not shown on graph

[lis o. <os...@gm...>]

Simple example:

--- A.php ---
<?php
class A extends B
{
    function aaa()
    {
        return;
    }
}
?>

--- B.php ---
<?php
class B
{
    function bbb()
    {
        return;
    }
}
?>

Debug message is;
##ERR##
Fatal error: Class 'B' not found in A.php on line 3

Off course, if adding require_once("B.php") to A.php, Both are shown.
But many case of today, autoload is deal with these relations.

...How can I do it?

Hi,

I've written a message to your bug report page but i think it's not shown
there or anythingelse.
I m using phpcallgraph to create sequence diagrams of our project. We have
a big repository to parse and when i execute the program i have just few
sequence diagrams of some classes.
I don't understand why i ve not the other classes sequence diagrams. All
classes are same types and i m using recursive option of corse. program can
find php files but startFunction dosen't start with all these files.
I ve tried to debug it but i couldn 't find the problem. Can you please
help me !

[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
at http://phpcallgraph.sourceforge.net

Direct Download Links:
http://downloads.sourceforge.net/phpcallgraph/phpcallgraph-0.8.0.tar.gz

Falko

Sorry for the late response. I had a little accident and got a metal bar into my

That's exactly the reason for using the Extended Reflection API of InstantSVC,
which is underlying the CodeAnalyzer and makes use of phpDoc annotations. Thus
phpCallGraph already has the information about parameter and return types. I
just didn't have the time to start using it.

The Extended Reflection API currently in the process of being contributed to eZ
Components. One of the next releases will start to be directly linked against
the latest ezcReflection component.

> Otherwise we should get the user to maintain a type overriding file.
This could be a nice additional feature for the reflection component. Do you
have concrete ideas how such a file should look like?

Falko

I would suggest to have a numeric option for that.

> Does my logic make sense?
Yes, it does. However, drivers are supposed to support multiple analyses on
different file sets, with reset being called after each analysis. Using the
destructor would only allow to get the data of last pass, but maybe that's ok,
for the beginning, since the umlgraph driver is working differently anyway.

[phpCallGraph-general] New release?

[Martin C. <mrj...@gm...>]

Hey Falko - can we get a release done please?

It seems that you are busy on other things, which is fair enough, but  
I need to get stuff "out there" to be able to publicise the work I did.

If you have feedback from you on the issues and solutions I've  
proposed over the last week I'll make time to process those within the  
week.

[phpCallGraph-general] Type hinting

[Martin C. <mrj...@gm...>]

Hi Falko,

It occurs to be that deriving types of all variables in php is going  
to be hard or impossible without extra information.

I see that coming from one of two sources: the user or/and phpdoc.

Can instantsvc see the @return typing information?

Otherwise we should get the user to maintain a type overriding file.

Thanks, Martin

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

[Martin C. <mrj...@gm...>]

Update on this: I checked in (I think svn:142) last night. As well as  
adding diagnostics showing the window around the current token  
position, it catches the condition of $myFoo = new Foo() such that  
subsequent accesses to $myFoo->methodName() are known to be on object  
type Foo.

Re: [phpCallGraph-general] dummyFunctionForFile_filename_php() ?

[Martin C. <mrj...@gm...>]

For anyone reading, I have a shell script that wraps classless php  
files into a class so they can be processed by instantsvc.

I gave Falko a copy: I think he's going to make the wrapping process  
transparent.

[Martin@Cleaver.org <Martin@Cleaver.org>]

See svn rev 142...

I hope it works for you!

Best,

[phpCallGraph-general] Getting depth of routines for a UML Graph Sequence Diagram

[Martin@Cleaver.org <Martin@Cleaver.org>]

Falko

It just occurred to me:

phpcallgraph does a lexical investigation (sequential as appears in
the source file) of the methods in a class. This does not do a
traversal according to how the methods are called.

It does hold an overview of the relationships after it has finished
(but doesn't know what's beyond the next layer during the
startFunction() and endFunction). During destruct, its seen
everything.  We know it knows because it passes all these
relationships to dot.

So, during destruct it would be possible to ask for a tree of
depended-upon methods for a given method. It would be possible to
visit each entry point method and to get all "dependent routines" that
need to be shown.

A question would be to what depth of dependents we would want to show.

Does my logic make sense?

Thanks,
   Martin.

[phpCallGraph-general] Open source UMLGraph mapping

[Martin@Cleaver.org <Martin@Cleaver.org>]

Falko,

You asked me whether I could contribute an example of an opensource project.
The reason I wrote the driver is that I'm analyzing a proprietary
extension of tikiwiki.

tikiwiki is utterly huge, so trying to understand what the coders have
been intending is a real issue.

To date I have only attempted to map out the extension.

But, as you asked, I am now trying it on the general open source part of it.

This will be a good test of how efficiently phpcallgraph scales in memory...

I'll report back!

Best,
   Martin.

Glad you like it!

I've created #phpcallgraph on irc://irc.freenode.net - can we meet
there and chat?
Also I added (the id of who I assume is) you to Skype. I'm mrjcleaver.
We could talk there.

Ok, I think I can live with it for now. Thanks :)

Ok. E

The HTML files were empty because I actually hacked a global variable
(eww!) in on my copy,
together with an apology pending hearing from you... I'm going to pass
the sourcecode

The PNG files could be empty if you didn't have UMLgraph installed
properly. I think all it needs is UMLGraph's sequence.pic and pic2plot
- but I had to upgrade a lot of software on my Mac to get everything
working so I'd to verify.

Will do, once I've verified it.
