Re: [PHP-DEV] Issues in passing session data
Hello,
please forward user questions to the [EMAIL PROTECTED]
mailinglist, this list is for development _OF_ PHP, not development
_with_ PHP.

Hi php users,
I have some questions regarding the way developers uses php sessions.
For instance, most developers uses session_start() on top of every page. The
problem is that after visiting each page, a new session file is created on
the server. Now i made a web application that uses the start_session
function on top of every page as follows:
?
if ($PHPSESSID){
session_start($PHPSESSID);
if (session_is_registered('valid_user')){
?
and it works. But now only one session file is created on the server.
Is this the best way of passing session data??

Re: [PHP-DEV] [PATCH] - fix for 64 bit issues with OnUpdateInt
A single API is probably sufficient but I can understand that extension writers might want to use ints. The INI flag might have nothing to do with an internal zval and an int might be more than enough. I don't really mind but I wouldn't introduce OnUpdateInteger. I guess we should either move everything to OnUpdateLong() and nuke OnUpdateInt() in ZE2 or we change OnUpdateInt to work with ints and fix the whole code. It might be less confusing to just have one. I agree about the confusing part. My suggestion is: * we leave OnUpdateInt as is currently for BC, deprecating it now, removing it in (? php 5.x == ZE2 ?) * convert everything in the code base to OnUpdateLong, which means I change the arguments passed into the call where needed (yipee I get to do another code sweep :-) This fixes the symantic problem and sets the stage for how to proceed in the future. * update the documentation with a note reminding people that int and long are not the same thing, both for OnUpdateInt and for zend_parse_parameters (I found zend_parse_parameters in the docs but not OnUpdateInt, any hints ?) I *think* this would work with all of the comments I have seen on this issue. I will start coding today, and if people are ok with it I will commit on Friday (to allow time for comment) so that Jani can move on 4.3.2. dave

[PHP-DEV] pg_lo_open and object creation... intended behavior?
Hi:
This is an excerpt from ext/pgsql/pgsql.c, in pg_lo_open:
---
if (strchr(mode_string, 'w') == mode_string) {
pgsql_mode |= INV_WRITE;
create = 1;
if (strchr(mode_string, '+') == mode_string+1) {
pgsql_mode |= INV_READ;
}
}
pgsql_lofp = (pgLofp *) emalloc(sizeof(pgLofp));
if ((pgsql_lofd = lo_open(pgsql, oid, pgsql_mode)) == -1) {
if (create) {
if ((oid = lo_creat(pgsql, INV_READ|INV_WRITE)) == 0) {
efree(pgsql_lofp);
php_error_docref(NULL TSRMLS_CC, E_WARNING,
Unable to create PostgreSQL large object.);
RETURN_FALSE;
} else {
if ((pgsql_lofd = lo_open(pgsql, oid, pgsql_mode)) == -1) {
if (lo_unlink(pgsql, oid) == -1) {
efree(pgsql_lofp);
...
}
... registers resource and returns ...
---
If I'm reading this correctly, it looks like a call to pg_lo_open (with
an object identifier specified explicitly in $oid) can theoretically
return a file handle pointing to a different, newly-created large
object in the case that the initial open failed.
If this is the case, it seems unintuitive and very cumbersome to handle
from user-space. Can we change the 'if (create) {' branch to only be
triggered when the oid was left unset (ensuring that the open() failure
actually gets back to the caller)?

[PHP-DEV] Question about zend_compile
I'm playing around with the compiler/executor and I was wondering if
someone could answer a question..
Is there any reasonable way to essentially push/pop the function table?
What I'd like to do is get a function_table hash for only a single file
(pesudo code below):
PUSH_FUNCTION_TABLE(CG(function_table))
Op_array = zend_compile_file(fh, ZEND_REQUIRE);
/* retrieve information from the function_table
about the functions in the fh handle only*/
POP_FUNCTION_TABLE(CG(function_table))
Specifically, I'd like to get the zend_function structures for the
user-defined functions declared inside of myfile.php... Basically my
problem is I have a userspace get_func_info($filename) function which
works great when retrieving information from the function table after
zend_compile_file(), but I end up having more functions than I wanted
since every user-defined function regardless of file (including the file
I'm in) is in the hash... i.e.
Myscript.php
?php
function foo() {
}
/* supposed to return an array based
on the function declarations in myfile.php, but it includes
foo() because it's already in the function table when zend
compiled this script. */
$info = get_func_info(myfile.php)
?
It seems to me that this is exactly the sort of thing I would want to
use namespaces for, is there a elequent way to create a new namespace
from within my C function temporarily between when my function is called
and returns?
Suggestions?

[PHP-DEV] 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]).
Threads would quite likely come in handy in the following situations:
- GTK-PHP thin network client application polling a socket for events
(e.g., IRC client)
- Multiple simultaneous connections to slow services (for instance,
think of whois + check multiple domain names).
Both of these examples could be realized using fork() or
socket_select(), though the first is not portable and the latter
produces unnecessary overhead.
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?

Threads for PHP
$Id$
1. API:
---
The thread API for PHP was designed to assemble that of Java (see
API documentation for lang.Thread).
2. Usage:
-
To create a thread, subclass the Thread class (defined in threads.c)
and overwrite its run() method. Put any code to be executed into this
function.
3. Basic example:
-
?php
class MyThread extends Thread {
public function run() {
print(thread init\n);
sleep(4);
print(thread finished\n);
}
}
$m= new MyThread();
$m-start();
// Wait for thread
print(main\n);
sleep(5);
print(main done\n);
?

[PHP-DEV] Doing something with an each opcode as zend_execute() handles it
Just before zend_execute()/execute() handles each opcode in its big switch() statement, I'd like to be able to call a function and pass it the opcode (or other information from the opline. Is the best approach to reset zend_execute to a new function in the PHP_MINIT_FUNCTION() (and restore the saved value in PHP_MSHUTDOWN_FUNCTION)? This new function would mostly be a copy of execute() in zend_execute.c with my addtional function call tossed in. What's the difference between zend_execute() and zend_execute_internal()?

I poked around PHP's CVS, and the bundled libgd reports having already been synched with 2.0.11, but something must have been missed as it fails like pre-2.0.11. I'll try and look at what might have been missed in the sync when I get some more time. For now, I've added it as a bug, http://bugs.php.net/22544 . The bundled gd in php 5.0 has been sycnched with gd 2.0.11, this was not done for version 4.3.2.

Yep
Int my_do_fetch_r_handler(ZEND_OPCODE_HANDLER_ARGS) {
fprintf(stderr, we hooked fetch_r\n);
return
zend_do_fetch_r_handler(ZEND_OPCODE_HANDLER_ARGS_PASSTHRU);
}
Is all you'd need.

[PHP-DEV] Resources and zend_register_list_destructors_ex
Hi, I'm having some trouble understanding persistent versus non-persistent resources (in ZE1). Does the Zend engine call _any_ non-persistent callback dtor function for a resource at the end of a request? For example: If I register a resource type at MINIT time like so: le_mod = zend_register_list_destructors_ex (destroy_mod, NULL, MOD_TYPE_NAME, module_number); then my resource will be destroyed at the end of each request. However, if I register a resource type at MINIT time like so: le_mod = zend_register_list_destructors_ex (NULL, destroy_mod, MOD_TYPE_NAME, module_number); then my resource will be destroyed at the end of the _process_. If I register my resource type like this: le_mod = zend_register_list_destructors_ex (destroy_mod, destroy_mod, MOD_TYPE_NAME, module_number); Is that the equivalent of registering a non-persistent type? thanks dave -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php

Maybe the userland API could be adopted by PECL/threads?

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..
