[PHP-DEV] Freeing memory
Hi, I am getting the following output from a php script that calls an extension I am writing (I have compiled the extension with --enable-debug) /home/phpcvs/php4_head/ext/pipe/pipe.c(245) : Freeing 0x0822568C (12 bytes), script=test.php /home/phpcvs/php4_head/ext/pipe/pipe.c(244) : Freeing 0x0822564C (12 bytes), script=test.php where lines lines 245 and 244 are: MAKE_STD_ZVAL(read); MAKE_STD_ZVAL(write); Does this mean that I need to free the memory from the zvals when the script exits, or is this just information?

Re: [PHP-DEV] Freeing memory
Actually zval_ptr_dtor() is probably more suitable. In any case, is this zval something you keep locally in your extension or are you returning/adding it to the engine's symbol table? If so, the engine should take care of the memory automatically as long as you've done everything correctly. Maybe you should explain in more detail what you're doing.

Re: [PHP-DEV] Return -1
On Sat, 9 Nov 2002, Maxim Maletsky wrote: I have just fixed a few doc files where it was stating that a function returned -1 but the sources had clear RETURN_FALSE. Done that, I took some time to grep my phpdoc and php4 trees for -1 returns and, surprisingly, I found out that there were a few suspicious places where -1 could be better changed to RETURN_FALSE. Some of such places were FTP, pgSQL, LDAP functions. Maybe a dozen or less in total. I don't think this should be done right now, as we would directly break the backwards compatibility. But, shouldn't we be considering such consistency changes for PHP5 releases? My point is that functions behaviour consistency can be very important for many users, and breaking just a few lines of PHP4 code since first PHP5 releases would probably be a small price to pay. I don't see any reason why we should break it and give users more headaches. Sure, consistency is nice, but IMO not worth it to break BC.

[PHP-DEV] abstract functions
Hi,
does PHP4 with the ZE2 supports abstract function like Delphi or C++?
That would be very useful for class development, cause we can avoid
testing if a class is abstract if an abstract class couldn't be
instantiated?
Syntax could be like in C++
class X
{
X(){}
int y() = 0;
}
or little bit more like pascal
class X
{
X(){} // PHP
function x(); abstract;
}
or
class X
{
X(){} // PHP
abstract function x();
}
Greetings,
Jens

Although it is sexy, does it make sense to users? Why would a fetch function accept an instance of an object? Just my .02 EUR:-) How about other db module maintainers? BTW, pg_fetch_object() accepted 3rd optional parameter for a long time. I've disabled it recently, since having $obj-1, $obj-2, and so on does not make much sense. I've done away with them.

Re: [PHP-DEV] Freeing memory
The whole picture is that i want to control a child process completely
from within php. A bit like popen or proc_open but with 2 independent
pipes to the child's stdin and stdout that I can read and write to. So
I'm basically wrapping the c functions pipe(), dup2() and friends. Once
I have it all working I will offer to add the functions into the pcntl
extension if they're wanted.
Anyway the code in the pipe function that was giving me the warnings is
as follows:
PHP_FUNCTION(pipe)
{
pipe_r_le_struct *st_pipe_r;
pipe_w_le_struct *st_pipe_w;
zval *read;
zval *write;
int pipe_fd[2];
if( pipe(pipe_fd ) 0 ){
php_error( E_ERROR, Could not create pipe );
}
st_pipe_r = emalloc( sizeof( pipe_r_le_struct ) );
st_pipe_w = emalloc( sizeof( pipe_w_le_struct ) );
st_pipe_r-fd = pipe_fd[0];
st_pipe_w-fd = pipe_fd[1];
MAKE_STD_ZVAL( read );
MAKE_STD_ZVAL( write );
ZEND_REGISTER_RESOURCE( read, st_pipe_r, le_pipe_r )
ZEND_REGISTER_RESOURCE( write, st_pipe_w, le_pipe_w )
array_init( return_value );
add_assoc_resource( return_value, read, Z_RESVAL_P( read ) );
add_assoc_resource( return_value, write, Z_RESVAL_P( write ) );
}
If i use FREE_ZVAL() at the end of this function I can get rid of the
warnings but I would guess this is the wrong place and it should be
taken care of in a cleanup function when the request has finished.
Please excuse me if I am missing something obvious here, as you may
guess I'm still finding my feet writing PHP extensions.

This didn't solve the problem. Each abstract class must check if it's
an instantiation of sth. is itself ...
Supporting an abstract feature like every OO-language would make it
much easier.
Of couse, since it is not available I use constructs like shown.
I didn't need help to find such constructs, I want suggest adding the
functionality for abstract methods.
I accept that in ZE2 no private methods are available. I even accept
that there's neither operator overloading nor multiple inheritation. And
even if I miss that most: that there will no access sections like in
Object Pascal or C++ (private/protected/public[/published]) and friend
declaration.
I just want suggest adding abstract feature, because that could make
many things more OO-like and much easier to maintain...
But thanks for the suggestions ...

testing if a class is abstract if an abstract class couldn't be
instantiated?
Syntax could be like in C++
class X
{
X(){}
int y() = 0;
}
or little bit more like pascal
class X
{
X(){} // PHP
function x(); abstract;
}
or
class X
{
X(){} // PHP
abstract function x();
}
Greetings,
Jens

Re: [PHP-DEV] Freeing memory
Hi Tony, What kind of things are you planning to do? proc_open seems ideal to extend for this purpose, and works on win32. --Wez.

A bit like popen or proc_open but with 2 independent pipes to the child's stdin and stdout that I can read and write to. So I'm basically wrapping the c functions pipe(), dup2() and friends.

[PHP-DEV] Configuration Patches
Attached are two patches that I've written to address a number of issues I've
come across while testing PHP on Solaris.
The first patch (alloca.txt) eliminated a warning message due to the fact that
that on Solaris and Tru64 alloca() is defined in a separate header, alloca.h,
which is not included. The current check only attempts to include this header
is the compiler in not GNUC, I came across the problem while using gcc 3.2,
which is becoming quite common on Solaris.
The second patch (flex.txt) is a flex check that ensures we are using the GNU
flex 2.5.4 (released in 1997, so it is safe to assume any recent distro has
it). If it is not found the configure script gives an advisory warning
similar to the one we give for bison. Only an advisory is given, because
unless PHP is compiled from CVS, flex is not needed.
This check is needed, because for example, the stock lexer installer on Sun
Os, does not support the -P flag needed by PHP and even though it passes
existing configure checks, it fails when it comes to generating the .c files.
Are there any objection to the integration of those 2 patches?

[PHP-DEV] php_embed and myphp
Hi,
I was testing myphp and it didn't work for me, because argv was initialized at
an inaccessible address.
Since I'm not farmiliar with C++, I made some changes using C, basically to
allocate a block for argv, and realloc when needed (see attached patch).
I know I still need to check reallocation in the other types, but that's
not the
issue.
I also made some changes to the Makefile, in order to use mysql_config, so
that's
why I changed mysql/mysql.h to mysql.h. Please excuse the hard paths there.
The following works once:
$ mysql
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1 to server version: 4.0.4-beta-log
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql SELECT php('strftime(%c, $argv[1])', UNIX_TIMESTAMP(NOW()));
++
| php('strftime(%c, $argv[1])', UNIX_TIMESTAMP(NOW())) |
++
| 11/09/02 21:22:57 |
++
1 row in set (0.02 sec)
mysql SELECT php('strftime(%c, $argv[1])', UNIX_TIMESTAMP(NOW()));
gdb output is attached and basically shows an error in the thread safety, which
I know very little about.
I'd appreciate any pointers in this area.
With kind regards,
Melvyn Sopacua

Yes, it has to be a POST request for there to be post data and $HTTP_RAW_POST_DATA is populated if the mime type of the data is unrecoginized or if always_populate_raw_post_data is on.

Re: [PHP-DEV] Freeing memory
Hi Wez, I wrote a pecl extension called ecasound which interacts with an audio processing library. Now the way that ecasound is written will change in future versions and will have a fully interactive mode, all other implementations (perl, python c++ etc) have been re-written so that they open up a couple of pipes, fork and then exec ecasound in the child process so using the interactive mode instead of linking against the librarys. What I would like to do is to make the PHP implementation work in the same way as all of the others but of course PHP does not yet have full 2 way communication with a child process. I agree that extending proc_open may be the best solution but while I would be willing to do the work I'm not sure that I can at the moment. Working with processes etc in c is fairly new to me and so are PHP extensions so trying to extend someone else's function that already looks fairly complex may be beyond me at this time (also I do not know anything about programming under win32). Maybe I'll take another look though as If this would really be the best way to implement the functionality I need then it may be a good learning exercise :) Tony On Sat, 2002-11-09 at 19:52, Wez Furlong wrote: Hi Tony, What kind of things are you planning to do? proc_open seems ideal to extend for this purpose, and works on win32. --Wez.

Re: [PHP-DEV] turning strlen() into an opcode
Here's the patch that Dan and I put together for the optimizer we talked about at the conference. It basically provides a defaulted-to-null function pointer that is the default case for the main execute() loop. This allows people to define their own opcodes without having to copy the source code for execute part and parcel into their own zend_execute() just to add a new opcodes. This is useful both for optimizers (like the one now in PECL/optimizer), as well as for implementing custom opcodes like what you want here without a huge engine patch.

[PHP-DEV] 64-bit PHP 4.3 (extensive long vs int problems)
Hi, Referring to bug #20268 (Bus Error on startup), I have added some comments about show-stopping problems with PHP 4.3 with regards to its lack of 64-bit cleanliness. The main problems seem to be Zend's OnUpdateInt (which seems misnamed although it uses zend_atoi, it assigns to a long) and PHP modules' use of zend_parse_parameters (which again acts on longs, not ints, though that has slipped by the authors of some modules). (Please forgive some of the less coherent sentences in my comments on the bug.) I have provided patches that demonstrate how I managed to get PHP working (in particular with SPARCv9 Solaris 8 and Apache 2.0).
