[PHP-DEV] Re: [Zend Engine 2] FYI: PHP/threads

I've been playing around with the (not new) idea of introducing threads
into PHP userland (maybe something to think about havin in PHP6?). What
came out of it is available at [1], offering an object oriented API (in
comparison to PECL/threads [2]).
 

-one of the reasons to not try object stuff initially (although it was 
in the todo) was to try and find out the issues :) - more below

Maybe someone here would like to pick up on this idea or give some
directions to what would have to be done to make this actually work
dependably. I'm experiencing the same issues as with PECL/threads -
variable "confusion" (local function arguments with same names in two
threads affect each other), Engine unstability (Warning: ... in ... on
line -18182899), but could get a couple of samples[3] to work quite
well.
Maybe the userland API could be adopted by PECL/threads? Is anyone still
working at this or was development given up?
not totally given up.. - but it's kind of a low priority unfortunatly 
(as it would be very nice)

To try and go through some of the issues with threads:
http://talks.php.net/show/kongress-gtk-future-2002/14
gives a few clues...
the reality is that all the zend_ctor... methods etc. are thread safe 
(assuming you compiled with the experimental zts flag) - this however 
introduces lots of problems when working with threads as the zend engine 
will allocate memory to the wrong thread, and hence try and free it when 
that thread closes.

what you demonstrated was the idea of copying the object instance from 
one thread to another (unfortunatly you also have to copy the object 
definition - eg. the opcodes) to make it work.. - whats worse is that 
you have to create memory that the engine doesnt know about.. - and then 
pass it too the new instance.. and tell the new instance that it is now 
incharge of that memory..

the idea of a thread_include() function was that it would be a starting 
point which would be idiot proof from the user (and less complex from 
the coding side..) - and would not involve the complexity of opcode 
replications (which would have to use something like the code in 
bcompiler..)

Hope this doesnt put you off.. - as I would still love to see it in PHPx 
somewhere :)

I guess the other issue was to try and ensure it was cross platform (as 
in reality most of those gtk apps are going to have to run on windows).. 
- so Shane did an amazing amount of work building the cross platform 
library..

Alan

It's not written in PHP - but it generates PHP code

In CVS is
phpLex a derivative of csLex (requires mono/.net runtime)
phpJay a derivative of Jay (a bison type grammer parser)
There are a few examples in the PHPSharp folder. look for .lex & .jay files.

phpLex is a bit better tested as I've been using it on

something similar in the works for PHP?

Re: [PHP-DEV] Reducing the number of system calls for includes

[Alan Knowles]

Apart from tidying up the include stuff.. - for this specific case, is 
it worth cosidering precompiling all the files into a single bytecode 
file?, thats what bcompiler ends up doing for classes.. etc. then 
manually indicate that you want to recompile the bundle, I'm guessing 
the actual PHP code doesnt change that much.. - (although bcompiler 
doesnt handle staightline PHP it might help on the classes..)...

Re: [PHP-DEV] $this scope (was T_PAAMAYIM_NEKUDOTAYIM)

[Alan Knowles]

It would be usefull to have a direction on this, - It's come up a number 
of times in bug reports.

It has a number of uses (primarily breaking large classes up, into 
smaller components..), and a clearer way to write code than using a huge 
inheritance tree.. - It may not be correct OO code, by the book, but it 
is usefull in certian situations.

It can be regarded as a feature, but if it is going to change at some 
point in the future, it's better to make that very clear now, rather 
than get a big backlash when we change it, and more people have worked 
out this little trick (and start to rely on it...)

Technically I guess overload is the real way it should be done in ZE2.

Should be to foo::bar NOT MyObject::MyObject. Which if my memory serves me

class?
 

Hi Brad,

Are you sure about that ? The manual states that this is the normal
behaviour which I find very handy and useful in many cases. I see a lot of
possibilities with this feature, for instance a way to develop some kind of
plug-ins for existing classes without having to extend them.
   


Where in the manual do you see this? 

 

This can probably lead to some dangerous code but this goes far beyond my
knowledge.
   


besides dangerous code if you find yourself doing this, you probally aren't
designing it correct. Your creating a static method of a class to access local
properties of another class thru the use of $this. If you want a way to access
member variables from a class in a static method, pass the object refrence into
the method.

Class foo {
function bar($obj) {
echo $obj->param;
/* $this should referr to the foo refrence, not another class refrence
*/
}
}

Class MyObject {
var $param;
function MyObject($param) {
$this->param = $param;
foo::bar($this);
   }
}

Re: [PHP-DEV] prototypes for getters and setters.

[Alan Knowles]

Actually looking at this in more detail, the solution PHP has infers 
that using $object->XXX='somevar' is heavily prefered over 
getXXX()/setXXX(), kind of against the grain for a classic OOP language 
(from the impressions have read), As refactoring (which is often the 
logic cited for setXXX()/getXXX() ) is handled by __getXXX() / __setXXX()

Obviously $object->XXX is going to be faster than $object->getXXX(), 
Would you say that the language design inherintly suggests you use 
$object->XXX.  (and basically forget about getXXX() methods?)

Or can any think if there any other reasons why $object->XXX = 'yyy' is 
normally disuaded in classic OO design.. (and I'm not talking about 
private variables :)

We do have an absolute standard: __get() and __set().

Re: [PHP-DEV] prototypes for getters and setters.

[Alan Knowles]

the trouble is that you will make pubvar a reserved word, and you force 
the user to use a fixed standard for set/get -- eg. some users may like 
get_orange, others may want getOrange
It also makes the assumtion that the user knows how the syntax works.. - 
eg. searching the file for  getOrange would return nothing...

$a = new foo();
$a->setmyfoo2(5);
echo $a->getmyfoo2();

$b = new bar();
$b->setmyfoo2(10);
$b->setmystuff(20);

The point here is that pubvar automatically creates get* and set*.. As
far as overloading, etc is concerned, there would be no need to worry
about it -- the point of these functions is not to overload them (they

[PHP-DEV] prototypes for getters and setters.

[Alan Knowles]

Thanks to a little chat (and a  few beers) with Zak at the conference, I 
got wondering if this syntax would be a sensible addition...

The principle is to enable rapid prototyping of getter and setter 
methods.

class something {
   var getBanana setBanana $banana = 12;
   var getOrange $orange =1;
   function setOrange($value) {
   if ($value == $this->banana) {
   echo "mmh banana's and oranges are the same";  
   }
   }
}
$t = new something;
echo $t->getBanana();
echo $t->setBanana(3);
echo $t->setOrange(3);

syntax:
  var [getter method] [setter method] $variable .;

or any other ideas
  var (getBanana, setBanana) $banana

  function var getBanana, setBanana for  $banana = '12'; // nice bit of 
token recycling.

  var use getBanana and setBanana for $banana = '12';


from a quick play with zend_language_parser.y the additionall code to

class_variable_decleration:

would look a bit like this...


| is_reference T_STRING T_VARIABLE  '=' static_scalar{
   znode tmp;
   znode tmpthis; 
   znode tmpfinalval;

   zend_copy_value(tmpthis, 'this', 5);
   tmpthis->type = IS_STRING;

   zend_do_declare_property(&$3, &$6 TSRMLS_CC);
   function.u.opline_num = CG(zend_lineno);
   zend_do_begin_function_declaration(&function, &$3, 1, 
$2.op_type TSRMLS_CC); }
  
   # get the 'this' part..
   zend_do_fetch_globals(&tmpthis TSRMLS_CC);
   zend_do_begin_variable_parse(TSRMLS_C);
   fetch_simple_variable(&tmp, &tmpthis, 1 TSRMLS_CC);

   zend_do_fetch_property(&tmpfinalval, &tmp, &$6 TSRMLS_CC);}

zend_do_return(&tmpfinalval, 1 TSRMLS_CC);
   zend_do_end_function_declaration(&$1 TSRMLS_CC);
  
   }

Anyway before I get carried away and actually test this :) - anybody got 
any thoughts.

Re: [PHP-DEV] I hope this is the last email about this :) (was RFC:CLI behave like SH or PERL/RUBY/PYTHON?)

[Alan Knowles]

Im +1 for reverting the patch - (for what it's worth)

Why?
Well - most 'average' (and below) PHP programmers when attempting to do 
CLI programming, will get a serious WTF reaction from wondering why when 
they 'echo' stuff, it doesnt appear. The more advanced Users can 
manually turn off flushing, but for most small, quick scripts (eg. 
50%+), this instant flush is going to be perfectly acceptable..

Anyway Just my 2c
Regards
Alan

It's a very _bad_ default. Fortunately, it's not released yet.
That's why I'm against it strongly.

IMO, flushing on every output by default is stupid setting.
If you ever programmed interactive programs, you should know
that unless you're ignorant about efficiency.

I guess my questions are too hard to be understood by you
compare to the last one. Derick, it seems you're alone so far.

http://news.php.net/article.php?group=php.dev&article=89995

Do you finally realize your argument actually did not make sense?
(Unless you need stupid PHP/CLI shell that requires start/end tag
to do anything, of course ;)

I'm going to fix it again unless many people want to make
PHP/CLI behave like a shell rather than programming language.

Alternatively, could you fix it again? (including Makefile.global)
Thank you and I hope this is the last mail about this.

PS: If you would like to write INI independent scripts, I
suggest you to use php.ini-recommended at least. You don't/
didn't know phps crashing and make test does not work well with
php.ini-recommended, nonetheless, you're insisting there is no
problems.

So, I'm sending this message, to the lists just to get any suggestions,
comments, feature requests, bug reports that you would like me to look
at/consider when revamping the extension.  The changes will be done step
by step to the extension, but the full revamping should be expected
around the time of PHP 5 (PHP 4.3 is too soon for all these changes to
be integrated and tested).

-Sterling

PS: I'll be at the PHP Conference in Frankfurt, and ApacheCon in Las
Vegas, if you're coming to either of those, feel free to talk about it
with me there as well...

At them moment, you can comment out the bcompiler_inherit call (it's

actually it's not needed 'at present' cause the compiled bytecodes do 
not use inheritance (as the compiled bytecode includes the 'merged' view 
of the class'..,however - if and when I get round to writing conditional 
method/var class compiling, it will be needed..

Is it worth adding a note to the output control page
http://www.php.net/manual/en/ref.outcontrol.php and/or ob_start to say
"Note: When upgrading from PHP 4.1 (& 4.2) to 4.3 that due to a bug in 
earlier versions you must ensure that implict_flush is OFF in your 
php.ini, otherwise any output withing ob_start, will be not be hidden 
from output"

or something similar?
(at least it will be documented, even if nobody reads it :)

Re: [PHP-DEV] php/embed

[Alan Knowles]

Going on a 'semi-consistant' naming structure on unix, would 
libphp.so.4.3.0 (softlinked to libphp.so) be an idea.

this should be really good when working with bcompiler_load_exe() :)

Re: [PHP-DEV] Apache 1.3, PHP and TSRM question

[Alan Knowles]

Are you dl('')'ing and modules,  - I think Zeev pointed me to a known 
bug with this if you have a memory leak from a dl'ed module it will 
crash on this type of debugging code (I think the filename gets freed 
when you unload the module at shutdown, and hence filename points to an 
out of bounds area)

I know it's a bit of a radical suggestion, but would depreciating

a better approach.

is there any reason to keep this in C?

dio - appears mostly stable = hell it's going in an embedded box here:) 
  its a straight map direct unix io stuff to php, so the api will 
probably not change, just grow slightly??
Sounds like it could loose the experimental tag.

pcntl  - have tested the latest changes that jason did. - everything is 
ok here. - the api is stable, and unlikely to have major changes (again 
it's a pretty straight C->php api)

anyway just my 2c

include is a parsed into a php opcode at compile time, you will need to 
look at Zend/execute.c in the big case loop, to find it. eg. it's not a 
php function as such.

Re: [PHP-DEV] Persistant global objects: WAS: RE: [PHP-DEV] ZendEngine2availability

[Alan Knowles]

I forgot msession extension. http://www.mohawksoft.com/phoenix/msession.html
the rpc extension may also be of interest - (not know the code that 
well, I'm guessing it may be able to provide a more efficient object 
serialization), although I doubt that the current string method is 
really that bad

Just a guess, but trying to isolate the data that needs 'sessionizing' 
and optimizing that, rather than planning object serialization (which 
may be easier to code),  may prove to be quicker to implement, although 
not as clean..

Re: [PHP-DEV] Persistant global objects: WAS: RE: [PHP-DEV] ZendEngine2availability

[Alan Knowles]

Sounds like a job for srm... http://www.vl-srm.net/

Obviously other options include SOAP servers.. etc.

or just using shm and storing a serialized object in there.

or use a ramdisk.

Something like this is difficult since php normally is not run threaded 
(eg. apache/cgi...) at the moment, so there is no 'central memory store' 
that could be used easily with it. - Apache 2 with thread support (when 
it is ready?) may help..

I'm sure theres a few other ways.

It's probably better  to discuss it on [EMAIL PROTECTED]

which version of php are you  building it with - I've mainly tested with 
4.3-dev, not tested in the last few days with php4.2*

Also please use the latest CVS version of bcompiler - I've just fixed 
the decompiling stuff today, so it should all be working. And there is 
an example of a full script compiler in the examples directory

(its easier to build as an extension) - just
download
run phpize in the directory
./configure
make install

no real need to put it in ext/bcompiler

(i need to update the manual to reflect that.)

Re: [PHP-DEV] cgi and mod_php (phpize)

[Alan Knowles]

On a related subject, one that has been bugging me alot recently is 
phpize & include dir's

I run 4.2* as apache mod, and 4.3-dev as cli, now when it comes to 
building modules I have to go back to the build directories and 
reinstall phpize each time.

I know I could change --prefix=, but it would be a bit nicer if phpize 
installed with a suffix and softlinked it'self to phpize
eg.
phpize-4.2.3   --> softlinked to phpize
phpize-4.3-dev

/usr/include/php4-3-dev
/usr/include/php4.2.3 --> softlinked to /usr/include/php4

anyway - just a thought...

Alan

bcompiler (pear.php.net) has a callback feature that can show you all 
the opcodes in php - I did it to play about with writing a PHP->C 
converter, (not that simple)..

somewhere between the two, you may find what you are looking for.

Re: [PHP-DEV] Interfaces in PHP

[Alan Knowles]

 From my reading of delegation, it's really overloading, worded slightly 
differently.. - but not that related to interfaces...

In the example below, which is a php'ized version of a C# demo, the 
advantages of using interfaces (as far as I know) are primarly useful 
for COM or CORBA, where it would be possible to generate all the 
components for a CORBA/COM/.NET, or even java binding by reading the 
interfaces.

A .NET binding would effectively define all the available interfaces and 
classes, with strong typing!, and then when called (from C# or .NET) 
invoke a C call to call_user_function, to run php exectuter 
(probably the best way to implement a .NET server in php, - compiling a 
loosely typed language into .NET bytecodes, from reading about 
python,perl etcs. experience is not the way to go..)

Other than being nice for documentation, in pure PHP, I cant really see 
them being much use...

Interesting subject anyway..

Regards
Alan

called from C#

PHP_Celcius c = new PHP_Celcius(12.9);
system.out(c.toFarenheight().toString());




Interface temperature {
 function __construct(float $value);

}

Re: [PHP-DEV] PATCH: debug_backtrace() function for 4.3-dev/ZE1

[Alan Knowles]

One another suggestion a change in  ZE1 that would ease transition to ZE2.

making
$object->__clone() work on ZE1 (eg. parse equivalant to $object) , 
(without having to add it to all classes that are likely to need it)..

would  at least enable code written for ZE1 work with ZE2.. and visa 
versa...

just my thoughts for the morning

the pcntl patch just fixes class based callbacks.. *the memory leaks I

Re: [PHP-DEV] phpthreads - hints anyone...

[Alan Knowles]

Ok, had a play with this
updated copy on
http://docs.akbkhome.com/threads.tgz

added a few of pthreads calls to TSRM.c

did most of the testing without this abstraction layer - just to see if 
I could get it to work.

used php_exectute_script, rather than getting clever and copying the 
function/class hashtables.

results:

It worked (with a few caveats - that are just a matter of getting to 
know threading better)...

some of the issues:
-if the child thread finishes before the main one - then the main one 
needs to wait somehow..
** FIX = probably need to keep a count of threads that are running and 
block at MSHUTDOWN on the main thread if stuff is still going.
-the child thread needs to have the modules functions loaded before it 
starts running really - otherwise you get intermitant 'functions not 
available' if you dont dl() the module in the child thread.
** FIX = I need to look at the pthreads equivalant for 
 tsrm_wait_event(thread.start_event,TSRM_INFINITE); will be.. this 
should make sure that the main thread doesnt do anything while the main 
thread is starting up..


- php_request_shutdown(NULL); calls the MSHUTDOWN for all modules - a 
good example of where this cause trouble is the ext/standard/string.c 
MSHUTDOWN, which has a static mutex that is freed. (and would be freed 
twice when the main thread finishes) -
hence  php_request_shutdown(), probably doesnt want to be called on a 
thread completion..
** FIX = not sure? - does this need fixing or should we just ignore 
php_request_shutdown..

due to the nature of thread scheduling, you dont get anything like '1 
opcode from thread A, 1 opcode from thread B', more like about 30-40 
opcodes randomly from each thread..

alan

 From my understanding they are 'forced to be isolated' by the TSRM 
stuff.  which looks like it stores globals in something like an 
associated array ( thread id => global c variable - eg. compiler_globals 
etc.), when ZTS is enabled..

the real use of the threading I guess is for people who want to write 
tcp servers, or desktop gtk apps.

Thoughts on accessing 'threaded shared vars'

$_THREADVAR['gtktext'] type..

php_threads_malloc_lock();
$_THREADVAR['gtktext']->add_text('some data ouput');
php_threads_malloc_unlock();

this would I guess involve rather heavy changes to the ZE engine to 
recogize an lock/unlock, copy (rather than refcount) etc. variables that 
where threaded..


Threaded objects???
 
I guess the other consideration is to have thread variable objects..
$threadvar  = new Thread_Var();
$threadvar->setNewObject('mywidget','GtkWindow');
$threadvar->set('mywidget',$gtkobject);
$var = $threadvar->get('mywidget');
$var = $threadvar->getArray('key','val');
$threadvar->callMethod('mywidget', 'add_text','something');

obviously copying and accessing these would probably be easier to cope 
with ( without having to modify heavily the zend engine) -  we could do 
'real' copying on the data, rather than refcounting them. and reduce the 
headaches...

Do you mean we will have to really physically copy the all theopcode 
data from one thread to another?

Re: [PHP-DEV] phpthreads - hints anyone...

[Alan Knowles]

 Ok, had a slight play with it again..

I did eventually find the perl code for threading although without an 
lxr server it's pretty much impossible to decipher all the macros they 
use..

The reality is I'm waving in the dark a bit - I've got a bit of spare 
time to play with it, but not really that sure whats going on all the 
time ;)

Working on the premise of thread creation starting another interpreter..
php compiled with --enable-experimental-zts, & debug. the code below 
manages to fire up the thread and run it.. - although it segfaults the 
main process after doing it.

This is a little supprising - I expected it to be the otherway round - 
as the logic kind of said that the new threads 'enviroment' (eg. vars) 
would not be initiated properly and it would fail.. , which could be the 
zval used in the callback causing issues..

The code for this stuff is pretty simple at the moment.. - so i'ts down 
the bottom..

As I said - if you can think of what needs doing, I've got a bit of time 
to play with it - although a little direction/hints do help..

alan

Plan A was just to get something that worked - even if it was crude and 
nasty... :)
Agreed - there are lots of issues with this method.. timesliceing and 
yeilding if the application is locked most of the time is problematic.

- do we have to do it based on perl - their web site is as easy to 
comprehend as the language - I spent 1/2 hour trying to find any source 
code or CVS server and failed :)
ok - hints would be good.. - pythons source for threading has a url...

I'm guessing this generaly means
a) turning on php's tsrm stuff.
b)on the
pthread_create():
copy the memory address of the function/class tables between threads. 
(eg. so they share the same data).
malloc lock any changes to the function/class table = eg. the compiler 
calls..
do the call_user_func_ex roughly as per before...

c) work out a sharing method for variables...

[PHP-DEV] phpthreads - hints anyone...

[Alan Knowles]

Im looking at adding threading to php, (for the cgi/cli stuff)..

The story so far:

I've created an extension which diverts all zend_execute calls into the 
extension -> phpthreads_execute.
this function is a copy of zend_execute with a few modifications
- to copy & restore things like  EG(active_symbol_table);
- to malloc lock and unlock the execute loop and release on each opcode.

I've started testing the phpthreads_create($callback); - it appears to 
work ok, execept it segfaults on completion.. - trying to reduce 
refcounts somewhere.

The fireup code looks something like this..

void phpthreads_create(void *ptr) {
zval myretval;
zval *callback = (zval *) ptr;
  
if (!call_user_function( EG(function_table), NULL, callback, 
&myretval, 0, NULL TSRMLS_CC ))  {
zend_error(E_ERROR, "Problem Starting thread with 
callback");
}
   
pthread_exit(NULL);
   
   
}
/* {{{ proto string phpthreads_thread(string function)
   Return a string to confirm that the module is compiled in */
PHP_FUNCTION(phpthreads_create)
{
 
zval *callback;
pthread_t thread;
   
  if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "z", 
&callback) == FAILURE) {
  return;
  }
pthread_create( &thread, NULL, (void *) phpthreads_create, 
(void*) callback);
RETURN_TRUE;
}

and the backtrace of the simple threaded test looks like this..
0x08128f08 in _zval_ptr_dtor (zval_ptr=0x81b5ce8) at 
/usr/src/php/php4/Zend/zend_execute_API.c:275

does anyone want to suggest what might be missing - is it worth putting 
this into pecl - and does someone what to lend a hand??

Re: [PHP-DEV] Patch suggestions for PHP 4.2.3 (tokenizer)

This would be nice to get into 4.2.3 - at least the tokenizer would be

[PHP-DEV] Re: [Zend Engine 2] can I have my delete back? :) - patch attached

[Alan Knowles]

Yeah, one of the main reasons for requesting it was that like shanes 
sybase class midgard also uses delete as the row deletor, - this doesnt 
really affect midgard as the method is defined in the php extension, not 
the php, however when I wrote DB_DataObject, and midgard lite, to take 
advantage of the same style of database access it was a pretty obvious 
method name..

one of the other ones that threw me was that 'list' did not work 
either.. (in ZE1 also obviously)..

looking at the code I would guess that you could support most valid 
keywords as method names

valid_method_names:
T_STRING
  | T_DELETE
  | T_LIST
  | T_NEW

the reasoning for not supporting all keywords?
 - user getting confused and accedentily using a keyword rather than the 
method

on the code side I cant see any major obsticales to supporting them.. - 
or did I miss something.. - the above code would add very little 
slowdown to the parser - especially as I assume it matches the first on 
the list anyway..

I did see it mentioned as a critisium that there where alot of reserved 
words that made defining class methods painfull ( I dont totally agree 
with that, but it would put it to bed)

alan

[PHP-DEV] can I have my delete back? :) - patch attached

[Alan Knowles]

 Attached hopefully is a patch to allow method names called delete .- 
not functions though..

Speedwise it should not affect performance as its a very small compile 
time issue..

this would save me an a few others a bit of pain :)

thoughts

Re: [PHP-DEV] PHP Extension Help

[Alan Knowles]

this is a good starting place
http://www.php.net/manual/en/zend.php

although it doesnt cover the class stuff that well (which can be done : 
ming, domxml,  gtk, xmms  - to name a few that do it )
- for a nice example have a look at the xmms extension
http://cvs.php.net/cvs.php/pear/PECL/xmms

This illustrates class and functional creation,

as a side suggestion it may be worth calling your class HTML_Template_XX
as this would fit in better with the PEAR naming of classes..

[PHP-DEV] php bytecode compiler

[Alan Knowles]

I've just been playing building a php bytecode compiler - based off of 
the apc serialize code. - made it thread safe and made it as a php 
extension that reads/writes streams - so it only works with 4.3-dev..

the tarball is at
http://docs.akbkhome.com/bcompiler-0.1.tgz

source files are here:
http://docs.akbkhome.com/bcompiler/

The current status is:
It can compile a class - example is bcompiler.php.txt
It can load a class - example is bcompiler_read.php.txt

It passes a few simple tests - although it currently segfaults if you 
call a static method of the class and dont use the class instantation 
stuff : eg. $test=new test12;

anyway for you want to play with it - and help fix it :) let me know

Re: [PHP-DEV] feature request for __LINE__, __FILE__ andtrigger_error

[Alan Knowles]

__LINE__ , __FILE__ (and now __FUNCTION__ & __CLASS__) are converted at 
compile time into a string - have a look at zend/zend_language_scanner.l 
 for more details.

Re: [PHP-DEV] The PHP Platform

[Alan Knowles]

I know this is going nowhere :) but anyway - its late here and I've got 
a few secs to kill

Ask your boss, how often has he done a project using microsoft tools, 
and its been seriously delayed because they found a serious bug in the 
microsoft tools, that had to be worked around.- if he answers never i 
would be amazed !

Delayed = late delivery = unsatified customer = bad reputation = no more 
contracts!

The difference with PHP (and perl,pike,python, ruby..etc), is that 
when there is a problem, your project is not delayed, you have full 
access to the source, you can find the problem, fix it and carry on with 
minimal delays.. - no workaround. - no code thats going to break on the 
next MS update!

This is the core to the reason behind why all of these languages are 
better than c#/java - you are empowered to solve your own problems, 
rather than relying on 3 levels of technical support and promises that 
it will be fixed and wont break your code.

the logic is in the philosophy not the marketing = no seminar is ever 
going to solve this problem :)

anyway -  just one angle to try

best regards
alan

Re: [PHP-DEV] FRC: pg_metadata, pg_convert, pg_insert, etc

 sounds really nice..
would it be possible to accept objects as well as arrays?
how does it know if the update column should be an integer or string - 
eg. '12' or 12 ? - is that what the meta data is for?

Re: [PHP-DEV] __CLASS__ patch - use $__THIS__ or class_get_called_name()?

[Alan Knowles]

As we chatted breifly on IRC,- Jani's patch implemented __FUNCTION__ and 
__CLASS__ as compile time values, hence in the example below they would 
return "base_class::test", and not extended_class::test





while this is also very usefull, the real desire/need I had was to get 
the 'called' class name (some examples of usage are below), which is a 
bit more complex to retreive: - as it is part of the calling scope of 
zend_execute, but not currently passed down to the running scope...

The implementation of this 'feature' does raise a few issue - should it 
be a constant, function call or a variable?

Constant: __THIS__
Unlike all other magic constants, like __FILE__,_LINE__ etc. it is not 
possible (AFAICS) to 'set' the value at compile time. - hence the rather 
chessy hack to the Constant callback on the execute loop. - The more I 
look at this the worse it looks :)

Function call: class_get_name() or class_get_called_name();
The present implemenation tagged extra information onto the function 
call (a pointer to the classname), I attepted to use a function call, 
this would involve adding an additional item to exectute globals eg. 
EG(active_class_name), and setting and unsetting,  before after each 
function call.

Variable: $_THIS or $THIS  or $__THIS__
This would involve pretty much replicating the current ZE1 code that 
creates '$this' and do something like if EX(called_class_name) ... make 
it as a zval in the called method's scope.
Considering this would __only__ happen on static method calls, and the 
size of the 'Class Name' is not normally Huge..., I think the very minor 
performance hit of creating this on static calls would be worth it. 
and is simple to implement as well.
(This is my favourite candidate at present :)
The last option does not alter any key 'structures', which I found broke 
the ZendAPI, causeing some zend extensions to segfault  :)


---Ok some code that uses it

class database_tools {
/* the normal 'get' method */

function &static_get($k,$v=NULL) {
$obj = new $__THIS__;
$obj->get($k,$v)
return $obj;
}

function get($k,$v=NULL) {
if ($v === NULL) {
$v = $k;
$keys = $this->_get_keys();
$k = $keys[0];
}
$this->$k = $v;
$this->select();
}
   
class db_users extends database_tools {
var $_table = "person";
function get($k,$v) {
$this->$k = $v;
if ($k = "firstname_letter");
$this->where_add("firstname like '$v%'");
$this->select();
}
}
class db_classrooms extends database_tools {
var $_table = "classrooms";
}

--- and the calling code examples...

$classroom = db_classrooms::static_get("number",12304);
$person= db_users::static_get(123);
$person= db_users::static_get("email","[EMAIL PROTECTED]");
$person= db_users::static_get("firstname_letter","a"); /

-- only way to do something similar without $__THIS__
$classroom = database_tools::static_get("db_classrooms","number",12304);
$person= database_tools::static_get("db_users",123);
$person= database_tools::static_get("db_users","email","[EMAIL PROTECTED]");
$person= database_tools::static_get("db_users","firstname_letter","a");

apart from the 'slightly shorter' naming :), the first example reads 
alot better.. - eg. I'm asking the users object for item 123..

whereas the database_tools is supposed to be a 'utility class' not an 
publically visable 'interface class'

that whole code could be simplified again if the get method knew it was 
being called statically.. and could call it'self!

[PHP-DEV] getting the called name from a static method - extending zend_function?

[Alan Knowles]

This is what I was trying to do,

class master {
function static_test($var) {
$class = get_class() <- this wont work obviously :)
$ret = new $class();
$ret->get($var);
if (!$ret->N) return;
return $ret;
}
}

class slave extends master {
 function get($var) {
   $this->N=1;
}
}

if ($obj = slave::static_test(123))
   $obj->do_stuff();
.

basically there is no way that I can see to get the called class out of 
the so that it would make a slave when called, not a master :)

 From a breif (well at least an hour or so :) look at the zend code - 
this was the solution i came up with - to extend the zend function to 
have an additional called_function_name pointer to store this in and 
have a extra magic define __CALLED_FUNCTION__

--- below are my notes how it might be done - is there any major 
objection/better ideas,  before I waste some time playing with it :)

Re: [PHP-DEV] DB Abstraction - db_oo - the query builder

[Alan Knowles]

As a side note to this, I did another major overhall to my query 
builder/ simplified db access layer, db_oo - and put up a small amount 
of documentation, although there is a small amount of mysql dependance 
in there, it's not impossible to remove...

http://www.akbkhome.com/Projects/db_oo%20-%20an%20object%20based%20Sql%20builder%20and%20wrapper%20for%20peardb/

It is an evolving tool, as its the base I use for a number of projects - 
it can build a object based data access to any mysql database within 
about 2 minutes, anyway if anyone wants to start thinking through 
ideas about sql builders, this does have alot of the 'chore work' done. 
Let us know if anybody is interested - it's API is still pretty flexible..

Re: [PHP-DEV] Floating point comparisons - A fix

[Alan Knowles]

wouldnt ~==  ,~>, ~<, ~>=  etc. be relivant here -
from what I remember of maths, (to long ago) ~ was the symbol for 
similar (and 2 together for approximatly equal) - hey even found a 
reference for it...
http://www.gomath.com/htdocs/ToGosheet/algebra/mathsymbols.html

the only thing is it would confuse perl people :) =~ (it;s the regex

[PHP-DEV] Re: [PEAR-DEV] Improving speed -> caching hash results in zend_execute?

[Alan Knowles]

Does anyone want to comment on this (the full threads on PEAR-DEV), 
about the results (2) and (3),  - 2 is a wrapper call to another 
function 3 is directly calling a function/method - I think it was 20,000 
times (1) is the original PEARdb call - with some extra ifs...etc.

anyway - the overhead for wrapping the call was quite high..

I had a look at the code in zend_execute.c (in ZE2 & ZE1) - the question 
goes something like this - I'm guessing that it's the hash table lookups 
being repeatedly called causing this slowdown. (couldnt see anything 
else...)

Would it not be an idea to cache in the opcode for the function call the 
result of the last hashtable lookup, then check if that lookup was valid 
first rather than doing a hashtable lookup on each call?

(or am I talking out my ass :)

Re: [PHP-DEV] Vote on New Build System

I presume that the old
PHP_EXENTSION() still works in V5
so modules outside the php tree can keep using it? ... and put in
dnl PHP_EXENTSION_NEW.
so it's V5 ready...

Re: [PHP-DEV] [PROPOSAL] defense against session takeovers

[Alan Knowles]

based on something nasty i did with cookies a while back

Session id
[][bb]
eg. first 32? chars are the standard md5, the remainder is a variable 
length key.

aaa - the standard session id. (eg. the filename)
bbb - an simple key overlay

say the session file contains
'abcd'
and
b contains
 0au2dr
then the resulting sessoin file would contain :
char 1 = (a + 0) mod 256
char 2 = (b + a) mod 256
char 3 = (c + u) mod 256

and so on. -- to decrept you obvious overlay the negative with modulus..

its an incredibly dumb and simple encryption method.. - but it may solve 
alot of the concerns...
- eg. without the full session id, you cant use the session file. or 
guess the full session file..

anyway its early morning so I probably missed something..
 - it doesnt make it impossible - just alot more difficult...

modfying the file io layer to deal with encoded (dump of the parsed data 
structs) files, is realitivly simple in theory, so if you have the 
time. :)

what I posted a while back was a method of merging php code into an 
extension. - It was theoretically postible to do that as well.., however 
it was not wonderfully effecient in terms of design. - you basically had 
to recompile the whole php binary just to use the code... - the nicer 
option would be what the old phpcompiler did - just add the code to the 
end of the php binary??? and do some other changes to make it execute 
the binary using the attached data. - If somebody could send me a copy 
:) - I'd love to see how that was done.. - searching google for 'merging 
data into exectutable binaries' doesnt get anywhere... :)
eg.
1. how does the php binary know where it's theoretical end point is, and 
the other data starts.. (guess work and looking for a data sequence?)
2. how does it read data from it's own internal memory, relative to the 
programs loaded memory space! - that one really threw me - otherwise it 
would have to load the file into memory, the re-read the data from it's 
own binary off the disk - sounds as bad as Plan A :)...
3. how can you make it cross platform!

from my aspect - looking at phpgtk apps, the compiled/protected bit is 
not important - its the distribution of a single exe + a few dll's 
rather than getting individual windows users to have a whole load of 
text files lying around.. - as everyone here knows there not much 
difference between the two - but try explaining that to the average 
windows IT manager =  saftey in familarity :)

[PHP-DEV] pthread & thread support : issues?

[Alan Knowles]

After spending yesterday looking at the pcntl library, I did at one 
point attempt to get create_thread going, It didnt get very far, (it 
segfaulted on emalloc - perhaps because thread_init had not been called) 
but I did start wondering about the feasibilty..

Has anybody ever attempted it?

The basic task of creating a set of php functions which wrapped the 
thread library - based perhaps on some of the code in python's thread 
library didnt seem particulary complex, however can anyone think of any 
issues that would occur?

Would it only work as a built in module rather than a loadable module?

anyway, I couldnt find any threads 'on threads:)' on php-dev discussing 
it - has anybody got any comments?

alan

[PHP-DEV] Fixes for pcntl - class support.

[Alan Knowles]

Well, after half a dozen bug reports that didnt actually work... - this 
one should, could somebody comment/commit etc.

The patch includes a number of changes... -
pcntl_zend_extension_active does not appear to be getting set when using 
modules
this little magic trick to get the zval stored in the hash table for 
callbacks

+   MAKE_STD_ZVAL(handle_copy);
+*handle_copy = **handle;
+zval_copy_ctor(handle_copy);

I deleted this as it was confusing me alot :) - obviously not essential 
to the patch
old_pcntl_signal_handler(int signo)

added a new function
pcntl_doevents = works a bit like gtk::do_events();
basically calls any pending signal callbacks. - as the 
 pcntl_zend_extension_statement_handler did not appear to get called 
when running from a module.

Re: [PHP-DEV] Re: [PHP] Re: [PHP-DEV] Re: Computer Science and PHP

[Alan Knowles]

This kind of bytes at a nerve when you are hunting for work and almost 
nobody mentions PHP here

Anyway, A quick few ideas to throw in the pot.. - Press releases, for 
PHP5 pre-alpha, PHP-GTK's, (Derick - srm?) upcomming release etc. which 
could be made available - Then a PHP press team??, could be resposnible 
for getting it out to the Press in their local countries..

I'm would hope that there a few people out there who could help out on 
this.. "Call for Volunteers..." - Either writing 'IT Press Friendly' 
release announcements, or gathering IT Press contacts, and faxing + 
emailing + phone followup on releases...

anyway my 2c for today.

regards
alan

interesting things that can be done with stdclass

Is there a proposed sytnax to stop copy by reference (Or did i miss it 
in the ZE2 docs)
old stuff
$object_copy = $object;  //(copy)
$object_copy = &$object;  //(copy reference)

new stuff?
$object_copy = copy_object($object);  //(copy)
$object_copy = $object;  //(copy reference)

[PHP-DEV] php compiler - (or really) big binary builder

[Alan Knowles]

Ok, this may seem totaly crazy :)

I was having a look at the issue of the php compiler (really 
distributing a single executable) of php code. - we are starting to 
develop php-gtk apps and it seemed usefull - it appears that the 
previous effort at doing this has dissappeared of the face of the web...

rather than get into the hard chore of actually building it against the 
bytecode, the idea was just to merge php code (either zipped) or just 
appended to the php binary, and making it execute code from the end of 
it'self..

eg.

| php binary |

| php raw code |


taking a bit of code from all over the place, I created a 'embedded 
extension' the core bit being below..


Now, it currently would assume creating a big '' area (where the 
echo'test' stuff is) which would replaced by php code by  a post 
processing on the binary..

It would be nice if the application could some how work out the memory 
address at the end of the php binary - where some kind of lookup table 
of all attached php files would be located...
other than that, an easy way to do an array rather than this hacked 
embedded_1 variable stuff... would be usefull...

--ideas would be appreciated..

anyway have a happy new year everybody..

regards
alan

Have a look through the mailing list archives (php-dev) - somebody has 
done this.

Re: [PHP-DEV] Re: PHP 4.1.0RC2 - can we roll?

[Alan Knowles]

This may sound a bit self interested, but the curl extension has a 
serious (well to me :) bug that prevents https working - If somebody 
wants to patch/test this - it would be one less bug in 4.1.0RC2 :)
-- I have done quite a but if testing here - (with and without openssl 
libraries)

This was due to an api change in libcurl in May - so I think most people 
would have updated their libraries by now.

Re: [PHP-DEV] Re: [PHP-GTK-DEV] Help - Merging Resource into a call_function array

[Alan Knowles]

Probably worth continuing on php-gtk-dev only...

I was getting a bit further with
MAKE_STD_ZVAL(myresource);
ZVAL_RESOURCE(myresource, gs) ;
/*ZEND_REGISTER_RESOURCE(myresource, gs, le_gtkhtmlstream); */
  now the function does not segfault, but does not appear to pass resource around..

then function below is called when the browser is loading a webpage, and wants an 
image, 
it emits a signal 'url_requested', which I have added a method of html 
connect_url_request.

this builds the callback data array in data, and calls this function.. - with a new 
stream.

- theoretically, when you load the web page, you would get  a number of these call for 
each of the images. the callback routine would then either get from the cache or open 
a non-blocking socket to get the file/image..

in theory a number of these streams could be open at one time (assuming the program 
can be taught to multi task well...)


on the php side..
it is supposed to work like this...

$string = implode('',file("http://www.php.net";));
$gtkhtml = &new gtkhtml();
$gtkhtml->connect_url_request("my_url_callback");
$gtkhtml->load_from_string($string);


function my_url_callback($url,$stream) {
  global $gtkhtml;
  $string = implode('',file("http://www.php.net".$url));
  $gtkhtml->write($stream,$string);
}

the code below just segfaults when url_requested is emitted.

with the modification above, $stream does not appear to be a resource... (although Im 
still testing..)

thx
regards
alan

[PHP-DEV] Help - Merging Resource into a call_function array

[Alan Knowles]

Can someone help me out with this one, - I'm sure that I've not acheived what I was 
aiming at - adding the Resource, myresource to the array prior to calling the callback 
function

the code below is from the url_request callback wrapper for gtkhtml - if this works - 
you can build a working web browser/editor in php.. 

regards

alan


static void php_gtk_html_url_request_callback (GtkHTML *html, const char *url, 
GtkHTMLStream *gs, zval* callback_data) 
{



zval *myresource = NULL; 
zval *retval = NULL;
zval **callback = NULL, **extra = NULL;
zval **callback_filename = NULL, **callback_lineno = NULL;
zval ***args, *params;
char *callback_name;
TSRMLS_FETCH();

zend_hash_index_find(Z_ARRVAL_P(callback_data), 0, (void **)&callback);
zend_hash_index_find(Z_ARRVAL_P(callback_data), 1, (void **)&extra);
zend_hash_index_find(Z_ARRVAL_P(callback_data), 2, (void 
**)&callback_filename);
zend_hash_index_find(Z_ARRVAL_P(callback_data), 3, (void **)&callback_lineno);

if (!php_gtk_is_callable(*callback, 0, &callback_name)) {
php_error(E_WARNING, "Unable to call ctree callback '%s' specified in 
%s on line %d", callback_name, Z_STRVAL_PP(callback_filename), 
Z_LVAL_PP(callback_lineno));
efree(callback_name);
return;
}

params = php_gtk_build_value("(s)", url);
ZEND_REGISTER_RESOURCE(myresource, gs, le_gtkhtmlstream);
zend_hash_next_index_insert(Z_ARRVAL_P(params), (zval *) &myresource, 
sizeof(zval *), NULL);

if (extra)
php_array_merge(Z_ARRVAL_P(params), Z_ARRVAL_PP(extra), 0);

args = php_gtk_hash_as_array(params);

call_user_function_ex(EG(function_table), NULL, *callback, &retval, 
zend_hash_num_elements(Z_ARRVAL_P(params)), args, 0, NULL TSRMLS_CC);

Re: [PHP-DEV] PHP 4.0.5 Release & Midgard Problems

Actually it's stable release went out a few days ago? - the midgard team
actually aimed at matching the PHP release cycle.. - all modifications
at present are pure bug fixes..

We are one of the bigger application developers on midgard (having done
nadmin http://www.hklc.com/midgard_manual), and also probably the bigger
bug finder & fixer - Midgard bugs are reported and fixed on it's own
mailing list - outside of php-dev. (considering the traffic here - It
helps everybody...)

In terms classing midgard as an extension, it seems that it is no
difference in terms of maintenance (QA etc.) to other extensions like
ming, xml ... (great work there too..)  

the whole extenstion scheme works very well, however the line between
'core extension' and 'other extension', has and probably will continue to be
vague.

Interestingly, Our test builds of midgard are always done against
packaged systems (arvins work on rpms - many kudos there). As the
generally we need to install midgard into production enviroments. So it
has been important to have midgard compile against earlier versions of
PHP4 - from what we saw, the backwards compatibility issue has caused a
few problems as the API in PHP4 gets modified slightly so it breaks this
compatibility. 

I would urge the PHP development team to support midgard module (just by
keeping it the core dist. under ext.)

Isnt that a bit like saying the XML module only provides functionallity
to a XML application.. 

end users - use the midgard functions - we have almost completed a port
of openmerchant to PHP4/midgard - it stores the templates and some
trasent data in midgard datastore, along with the page's - it adds a
level of security, reducing or removing the dependance of file system
write access.

[PHP-DEV] chinese patch for htmlspecialchars

[Alan Knowles]

hi, 
Just tryed adding chinese parsing ability to html specialchars, 
If you do any webdev in php in chinese, it is one of the annoying 'missing
features'


Can somebody help finish this off, There are 2 issues,
- I get compile time saying 
   html.c:76: warning: comparison is always false due to limited range of data
type
  (I'm not a C expert at all, is a (char *) expect to return < 127 ??)...


- I have no idea what type of wrapper check to check for character set or
locale 

Anyway heres the patch, If someone wants to comment on...
