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...

Re: [PHP-DEV] imap quota broken

[Dan Kalowsky]

Yes it did.  Mainly because the old compatibility was wrong.

In the case when a server would respond with multiple resources like so:

C: A003 GETQUOTA ""
S: * QUOTA "" (STORAGE 10 512 MESSAGE 5 256)

The imap_get_quota() function would set the usage and limit values to that
of the last resource.  If there is more than one resource, the last value
is NEVER the STORAGE value.  The current functionality reflects the proper
usage and limit values for all resources, and conforms to RFC 2087.

No offense, but I think other developers should be mentioned as well. I very
much like wez' work on innovative ideas - even though his results might not be
suitable for the masses (such as having PHP client-sided embedded into redmond's
browser etc.).

But generally, I think honoring hard working developers is a good idea, as they
only seldomly get positive feedback on their work (what they certainly deserve).

[PHP-DEV] imap quota broken

[Jan Schneider]

One of the lasts commits to the imap quota functions broke backward
compatibility with the old imap_get_quota() behaviour.

It used to return an array like:
array ( 'usage' => 83090, 'limit' => 10, )
but now returns an array like:
array ( 'STORAGE' => array ( 'usage' => 83090, 'limit' => 10, ), )

[PHP-DEV] mbstring and html encode/const structs

[Marcus Boerger]

Hi,

i have changed two things in ext/mbstring:

1) i changed all structs to be const to prevent compiler warnings and 
programming errors.

2) i implemented a html encoding.

at this time i have input decoding simply as a pass by and output encoding 
that produces
named or numeric entities for html output. This way i can enforce the 
engine to deliver
entities in output.

At this point it only works with characters < 256. I guess the problem has 
something
to do with internal handling of characters > 255.

Anyone interested may download the patch: 
http://marcus.boerger.de/php/ext/mbstring/mbstring-entities-const.patch
And the additional file holding translation the table: 
http://marcus.boerger.de/php/ext/mbstring/html_entities.c

If the idea finds friends i will check this in and invent some more work in 
decoding and encoding.

Example script:
--


ext/mbstring HTML Encoding Test Page








--

The above script will output the first php line just as the second one:

Precision is questionable but rounding errors cannot be. Two integers
multiplied will always have .00 ... Infact i am nearly sure that double
precision is enough...

Ouch.  While it's an interesting way to deal with the issue, I think 
this will be way too slow, and maintenance will be hard (keeping up with 
changes in the real zend_execute, and zend engine in general).  As in a

[PHP-DEV] Re: [PHP] mcrypt

[J Smith]

If all you need is some generic encryption that doesn't require mcrypt, you 
might want to take a look at a crypto extension I wrote called 
cryptopp-php. It does everything that the mcrypt extension does and might 
be a touch easier to use as far as syntax and such goes. (Plus, it works on 
Windows if you're into that sort of thing.) It's fairly stable at the 
moment, and doesn't have the memory allocation problems.

See http://www.tutorbuddy.com/software/, and 
http://www.tutorbuddy.com/software/cryptopp/ for the manual.

(I hate the shameless plugging, but the more people who use my extension the 
easier it is for me to debug...)

RE: [PHP-DEV] Moving away from ASP to PHP

[Preston L. Bannister]

By "as many platforms as possible" do you mean different web servers on
Windows (in which case using ActiveX components is viable), or different
operating systems (Linux? Apple's OS? Sun? z/OS?)?

Which specific platforms do you have in mind?

I would not ordinarily recommend writing code in C unless absolutely
necessary.  What skills currently exist within your programming group?
Which of those people are interested in learning new technologies, and which
will resist?

All the above will influence your choices.

BTW - some portable equivalent to COM/ActiveX components would be great.
The Mozilla project has XPCOM but I have no opinion on how well this was
done.  If XPCOM has any legs outside Mozilla then building XPCOM support
into PHP could be a big win.

I've recently joined a new company and we're doing all of our web
development (server-side) in ASP at the moment.  We have to create a rather
large scale application that will run on as many platforms as possible, so
you can see how IIS can be restrictive to us at this point.  The one thing
that is imperative that we do, is to be able to hide the code of the
application.  In ASP, we would simple make a DLL and then create the COM
object from the ASP scripts.

I'm not the best with the Unix/Linux flavours of this sort of thing, so I'm
not quite sure how we'd accomplish something of the same sort.  I've been a
PHP programmer for over a year at my old job, and I -definitely- prefer it
over ASP or JSP as a scripting language of choice.  I looked into making
modules (binaries?) and then re-compiling them with the code to hide them.
I assume this would mean we would have to write our code in C and then
recompile from there?

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

[Jason T. Greene]

Instead of mutexing the entire interpreter to death, why don't you try
creating multiple interpreters (each in a thread), and then come up with
a sharing mechanism.

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

[Brad LaFountain]

This is interesting Shane and I started talking about php threads at OSCON.

But baiscally your soulition won't work. I can't remember the specfic reason. I
think i tried the same thing along time ago. If it were that simple it probally
would have been done already :).

For threading php you will need to have each php thread have a seprate
interperter. So then you would need some way to share variables between php
interperters ($_SHARED[] possibly). The $_SHARED (or equiv) would need
read/write locks around the access to the variable. Shane and a few other
hashed some ideas at the confrence and with stealing some ideas from perl we
came up with a decent soulition. You might want to get ahold of him and see
what he is going to do with it.

[PHP-DEV] gc impossible if session.save_path depth > 2 ?

[Giancarlo Pinerolo]

Many hosted sites would like to keep their session.save_path separate, within their 
home dir, but are somehow prevented by the fact that gc wouldn't take place if the 
path depth is > 2.

Because they obviously see a problem in implementing their own garbage collection, as 
most hosting sites  do not offer a shell nor the possibility to set up cron jobs to do 
that, most give up that, and decide to drop their session in the common cauldron.

I went through php code, and it seems that this limit is just hardcoded in there.

I mean, is there a valid technical reason for this limit to be there or...

[PHP-DEV] Weird?!?!

[Stefan Esser]

Hi,

Could someone tell me why the Zend Engine calculates every multiplication
2 times???

zend_operators.c:

ZEND_API int mul_function(zval *result, zval *op1, zval *op2 TSRMLS_DC)
{
...
if (op1->type == IS_LONG && op2->type == IS_LONG) {
double dval = (double) op1->value.lval * (double) op2->value.lval;

if ((dval > (double) LONG_MAX) || (dval < (double) LONG_MIN)) {
result->value.dval = dval;
result->type = IS_DOUBLE;
} else {
result->value.lval = op1->value.lval * op2->value.lval;
result->type = IS_LONG;
}
return SUCCESS;

...

should that be replaced with:

result->value.lval = (long)dval;

instead of calculating the multiplication again???

[PHP-DEV] RE: [PHP] Re: [PHP-DEV] [CROSS POST] PHP Meetup & Texas PHP Users

[Jay Blanchard]

[snip]
First of all, sorry for the additional cross post. MeetUp.com lacks the
ability to let you contact other folks who have signed up. In my general
area, Massachusetts, there are a bunch of tiny groups scattered about,
and I'd like a chance to get all of them to converge in one place to make
the meetup worth it for all of us. I know there's only a few days before the
meetup is to take place, but if folks from the following areas could email
me, then we can try and work out somewhere we can all meet, instead of there
being 5 groups of 2 or 3 people.
[/snip]

Agreed Gabriel, meetup.com, while a nice idea, does not work well at all due
to the lack of contact information provided. But look what it may have
started!

I encourage PHP developers to seek each other and form their own groups. But
even the PHP lists barely scratch the surface of developers who are out
there. Contact other computer users groups in your area and you may be
surprised at what pops-up.

[PHP-DEV] Scripts running on two different browsers crashes the server

[Ananth Kesari]

Hi All,

I am porting PHP for NetWare. I have run into a problem during unit
testing and I seek inputs from you on this.

I am using two scripts:
1. In one, I am using a simple while loop:
";
}
?>

2. In the other, I am just displaying the PHP info using


If I run these scripts individually, it is fine.
Even if run the while loop script simultaneously on two different
browsers, it works fine on both the browsers.

But if I run the first script (while loop) in one browser and while it
is running, if I run the second script from another brower, then my
NetWare server crashes. Strangely, the PHP info output from the second
browser is getting displayed on the first browser (!) where only the
loop numbers are supposed to be displayed. The font and size of the
display also changes. The server abends before the loop is completed.
Nothing is getting displayed on the second brower.

When I walk through the stack, I find that the abend seems to be
happening in the "_zval_ptr_dtor" function that is called after the
function, "zend_stack_apply_with_argument" is called which in turn is
called by the "execute" function.

I feel this may be due to data corruption between different threads in
some specific cases. Is it due to the usage of global variable or the
usage of static variables that are shared across threads?

I would greatly appreciate if anyone can throw some light on this.

Please note that I am using the PHP development version 4.0.8.

Thanks,
Ananth.

Re: [PHP-DEV] Addition to the openssl ext

[Wez Furlong]

Hi Thomas,

Just so you know who I am, I'm the openssl extension maintainer :-)

I'd like to see your patch integrated into a more generic encryption
function call, where the cipher is passed as a parameter.

So, I don't think we will integrate your patch as-is, but do think
we can implement the same functionality using a function something
like this:

mixed openssl_cipher_encrypt(int cipher, string key, string plaindata);
mixed openssl_cipher_decrypt(int cipher, string key, string cryptdata);

The functions would return false on error or the (de)crypted string
on success.
The ciphers would be registered as constants like this:
OPENSSL_CIPHER_BF_CFB64
OPENSSL_CIPHER_X

Could you log your patch as a feature request using bugs.php.net so
that I can find it when I get around to implementing this?

If you are able, it would be really, really appreciated if you could
help with the groundwork for this: if you can find out how to do this
generic encryption using C code (it doesn't have to work with PHP; it
can be a small hacked up C program) and post it along with your original
patch, it would help a great deal!
I tend to use the source for the openssl command line program as a guide,
so that's where to check first.

To get the idea of what I talking about we want something like this:

CIPHER_METHOD cipher; // This is a pointer to the cipher method

switch(cipher_number) {
case OPENSSL_CIPHER_BF_CFB64:
  cipher = CIPHER_BLOWFISH;
}

CIPHER_Encrypt(cipher, key, data);

So we just need to find out the names and types of the ciphers and
related functions.

Thanks for your contribution!

--Wez.

[Stuff about blowfish encrypt/decrypt was eaten by my MTA]

PS: I've Cc'd this to Derick who is working on a generic encryption
extension for PHP and who might have some comments on the API,
although he is on vacation at the moment.

[PHP-DEV] Moving away from ASP to PHP

[Anthony Kauffmann]

Hi all,

I've recently joined a new company and we're doing all of our web
development (server-side) in ASP at the moment.  We have to create a rather
large scale application that will run on as many platforms as possible, so
you can see how IIS can be restrictive to us at this point.  The one thing
that is imperative that we do, is to be able to hide the code of the
application.  In ASP, we would simple make a DLL and then create the COM
object from the ASP scripts.

I'm not the best with the Unix/Linux flavours of this sort of thing, so I'm
not quite sure how we'd accomplish something of the same sort.  I've been a
PHP programmer for over a year at my old job, and I -definitely- prefer it
over ASP or JSP as a scripting language of choice.  I looked into making
modules (binaries?) and then re-compiling them with the code to hide them.
I assume this would mean we would have to write our code in C and then
recompile from there?

Any help or suggestions would be greatly appreciated.  Thanks.

Anthony

well, not until it doesn't segfault after every request, no. :)

I'd also think you'd need a quite larger subset of Pthreads, and perhaps
focus on an OO solution (like what Perl does), but that's all surrounding
elements.

Good luck with threading the Zend Engine :P

[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
275 (*zval_ptr)->refcount--;
(gdb) bt
#0  0x08128f08 in _zval_ptr_dtor (zval_ptr=0x81b5ce8) at 
/usr/src/php/php4/Zend/zend_execute_API.c:275
#1  0x424ceba2 in ?? ()
#2  0x424c7c92 in ?? ()
#3  0x08130588 in zend_execute_scripts (type=8, retval=0x0, 
file_count=3) at /usr/src/php/php4/Zend/zend.c:810
#4  0x08110abd in php_execute_script (primary_file=0x40006c71) at 
/usr/src/php/php4/main/main.c:1398
#5  0x08110138 in php_module_shutdown () at 
/usr/src/php/php4/main/main.c:1058
#6  0x2e325f43 in ?? ()

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

regards
alan
