[PATCH] Closures and reflection improvements

Hi,

I'd like to add the following patch to reflection before the feature
freeze, because it does not change any current reflection behaviour but
adds quite a bit of good stuff for closures.

With the current closure implementation, __invoke always has the same
signature as the original lambda function, this makes passing parameters
per reference possible. But this does not show in current reflection:

$o = new ReflectionObject (function ($a) {});
$m = $o->getMethod ('__invoke');
var_dump ($m->getNumberOfParameters());

Currently, this does a lookup in the class function table. But the
signature of the method found in the function table has no parameters.
For the normal engine to have a different signature for a specific
closure, the get_method handler is used.

My patch does the following:

If a reflection method named '__invoke' is requested for an object
of the 'Closure' class (in any way possible: via constructor,
via ReflectionObject->getMethod, via ReflectionParameter
constructor, ...), the correct invoke signature is used by
reflection.
If the same method for the class 'Closure' (without an object)
is requested, the standard signautre (no parameters) will be used.
If you pass a callable object (closure or otherwise) as the only
parameter to the ReflectionMethod constructor, __invoke will be
used as default method. Example:
$m = new ReflectionMethod ($closure);
is identical to
$m = new ReflectionMethod ($closure, '__invoke');

For Post-5.3 we could even think of adding a new object handler for
retrieving methods for reflection generally (get_method will not work
correctly since the std_get_method handler does scope checking and
prints error messages) and thus allowing e.g. COM, Java or SOAP objects
to provide useful dynamic information for reflection. But to keep the
changes in 5.3 as non-invasive as possible, it is probably best to have
this single exception for closures.

You can find the patch here:

http://www.christian-seiler.de/temp/php/2008-07-24-reflection/reflection-closure-fixes-5.3.patch
http://www.christian-seiler.de/temp/php/2008-07-24-reflection/reflection-closure-fixes-6.patch

The patch is fairly straight-forward and should be easily reviewed.

Here are some tests for this patch:

http://www.christian-seiler.de/temp/php/2008-07-24-reflection/reflection-closure-tests-5.3.tar.gz
http://www.christian-seiler.de/temp/php/2008-07-24-reflection/reflection-closure-tests-6.tar.gz

I also found a segfault in all PHP versions in the ReflectionParameter
constructor. The above patches already fix that, but here's a patch that
fixes this for PHP 5.2:

http://www.christian-seiler.de/temp/php/2008-07-24-reflection/reflection-segfault-fix-5.2.patch

For the segfault I also created following test case (works with 5.2, 5.3
and 6.0), NOT included in the above .tar.gzs.

Hi,

http://www.christian-seiler.de/temp/php/2008-07-24-reflection/reflection-closure-fixes-5.3.patch

http://www.christian-seiler.de/temp/php/2008-07-24-reflection/reflection-closure-fixes-6.patch

The last CVS commit for apply_func_t and TSRMLS_CC conflicted with the
patches, I merged the conflicting line manually and reuploaded the
patches to the same location.

Hello Christian,

patch looks fine and should go in.

do you think ReflectionMethod::__construct implementation could be done
using parameterparsing 'f' rather than the spcial case 'o'? Unfortunately
we would still need the zs version unless we add another 'F' parameter
parsing that allows this two parameter case as well.

Thanks.

The Problem with 'f' is that it will accept every callback, even normal
functions, so that would kind of break the idea of having
ReflectionMethod different than ReflectionFunction.

So in my eyes, using 'o' for now is the sanest approach.

Christian

I see. So if we ever want to fix it we need 'm' for method then :-)

Hi Marcus,

I have no objections against ZE part of the patch.
If you like ext/reflection part please commit the whole patch.

Thanks. Dmitry.

Hello Christian,

I updated your patch for 5.3 due to recent changes. It works pretty fine
for me. Care to test again, especially with your new tests? Note that test
ext/reflection/tests/closures_001.phpt does not work for me and I have no
clue why. Well, besides that obviously the closure class no longer has an
entry for __closure, so it is more a question of how to know when to add
this. Also, it appears you do not have a cvs account, or did I overlook
something?

Modified patch attached, including the updated reflection tests.

Hello Johannes,

I addressed the thing you spotted.

Ok, it is actually easy to fix, we just check whether the thing is a
closure and add the method manually, done. New patch attached.

Johannes, this also adresses the switch from E_ERROR to E_RECOVERABLE_ERROR
for the closure handlers.

Hi Marcus,

I committed the ZE part of your patch with exception for

zend_error(E_ERROR, "Cannot destroy active lambda function");

Catching this error may cause memory corruption and crash.

Hi,

all submitted now. Thanks everyone for their help and especially
Christian for getting this started.

Thanks for making my patch work after the modifications in
zend_closures.c. I'm sorry I couldn't do it myself but I was kind of
busy the last few days and the "simple fix" created memory leaks and I
didn't want to post a knowingly broken patch.

Anyway, there are still segfaults in the current version:

$foo = function ($a) {};
$o = new ReflectionMethod ($foo);
$p = $o->getParameters ();
unset ($o);
$m = $p[0]->getDeclaringFunction ();
Reflection::export ($m);

$foo = function ($a) {};
$p = new ReflectionParameter ($foo, 'a');
$m = $p->getDeclaringFunction ();
unset ($p);
Reflection::export ($m);

This is due to the fact that getParameters() / getDeclaringFunction()
don't copy the fptr and fptr->common.function_name pointers if it's a
closure. Here are patches for PHP 5.3 and HEAD that fix the problem:

http://www.christian-seiler.de/temp/php/2008-08-11-reflection/segfaults-5.3.patch
http://www.christian-seiler.de/temp/php/2008-08-11-reflection/segfaults-6.patch

Also, the following test that I already posted should be added to
PHP_5_2, PHP_5_3 and HEAD:

http://www.christian-seiler.de/temp/php/2008-07-24-reflection/reflectionParameter_invalidMethodInConstructor.phpt

The test already works for PHP_5_3 (since the fix for that was included
in my original patch) but a segfault still occurs in PHP_5_2 and HEAD,
my patch that I already posted fixes that problem for 5.2:

http://www.christian-seiler.de/temp/php/2008-07-24-reflection/reflection-segfault-fix-5.2.patch

My original patch also fixed the problem for HEAD, I readded that part
to the above segfault patch for HEAD.

Also, it appears you do not have a cvs account, or did I overlook
something?

No, I don't. Dmitry also mentioned that - should I request one?

Christian

Yes, please do and the seg fix patch should have a function to do the

Account approved and access granted. Please provide the function copying in
a function next to _free_function() and care for parameter info as well
(yeah sorry for the additional work). And then, happy submitting.

Also for your next patches (cvs di -N) allows to ship the new files in the
patch and (cvs di -Np) shows the context, which makes reading the patches
easier.

Please provide the function copying in a function next to _free_function()

I just committed that (and included some tests). I hope I didn't do
anything wrong in the process, if so, feel free to do so.

and care for parameter info as well

I assume with parameter info you mean arg_info? That isn't necessary and
actually harmful since the arg_info is not copied but simply referenced
via a C pointer in closures (zend_get_closure_invoke_method copies the
entire function structure, including the pointer to arg_info and only
changes some flags the function name). There is no need to copy or
destroy arg_info in reflection.

Also for your next patches (cvs di -N) allows to ship the new files in the
patch and (cvs di -Np) shows the context, which makes reading the patches
easier.

Ah, thanks, I added that to my .cvsrc.

Regards,
Christan

Oh, cool. I thought we'd have to do more stuff.

Hi Dmitry, Hi Marcus,

I have no objections against ZE part of the patch.
If you like ext/reflection part please commit the whole patch.

Due to your cleanup wrt. handlers the reflection part will currently
(probably) segfault. I'll post an updated patch for this tomorrow.

Regards,
Christian
