[PHP-DEV] readfile() suggestion
Hi,
i've a small suggestion to improve the behavior of the readfile()
function.
First, since the command use the php streams, sometimes php crashes,
especially with big files (10MB).
Also, if you output a file with readfile(), the memory consumption is
excacly the same as the reading file.
I using the readfile command to deliver files with a typical
content-disposition header, but since i have some 'big' files, i've
change the delivering to this small code:
?php
$filename='megafile.txt';
$fh=fopen($filename, 'rb');
if ($fh!=false){
while (!feof($fh) !connection_aborted()) echo fread ($fh,
8192);
fclose($fh);
}
?
On a 2 MB file, this script needs 35KB (test is with a php_memory log)
and the readfile version needs 2MB.
I think it is also possible to reduce the memory consume in the
readfile() command, because it is not required to read the complete
file first and than output it.
The problem is in the php_stream_passthru function. We need a
sapi_flush(TSRMLS_C) or php_end_ob_buffer(1, 1 TSRMLS_CC) call.
Not only the readfile command is affected, also the gzpassthru command.
Any comments?
Best regards,
Steve

[PHP-DEV] pcntl_signal problem
Hi,
i've a small problem with the signal handler.
These short script demonstrate my problem.
#!/usr/local/bin/php
?php
set_time_limit(0);
function signals($signo) {
switch($signo) {
case SIGTERM:
echo Termination signal;
exit;
break;
case SIGINT:
echo Interrupt from keyboard;
exit
break;
}
}
$result=pcntl_signal(SIGTERM, 'signals');
if ($result == false) echo 'could not install sighandler for TERM';
$result=pcntl_signal(SIGINT,'signals');
if ($result == false) echo 'could not install sighandler for INT';
echo goto loop ...\n;
$c=0;
while (true){
$c++;
usleep(1);
}
?
The problem is, that the script doesnt exit when i'm
sending the TERM signal or pressing CTRL-C (INT signal).
I've test it with the lastest cvs version.
Any help?
Regards,
Steve

[PHP-DEV] file_register_wrapper not binary safe?
hi,
i've made some tests with file_register_wrapper and a possible
my-own-get-from-variable-instead-of-file-handle wrapper, but i think
that the stream_open function handler is not binary safe.
Here a small code snip to demonstrate the problem:
?php
class variable_stream {
var $data;
var $data_length=0;
var $pointer;
function stream_open($path, $mode, $options, $opened_path)
{
// not really elegant, because the class don't know
// the own name
$this-data=substr($path,11);
$this-data_length=strlen($this-data);
$this-pointer=0;
return true;
}
function stream_close(){
unset($this-data, $this-pointer);
}
function stream_read($count)
{
$returnvalue=substr($this-data,$this-pointer,$count);
$this-pointer+=$count;
return $returnvalue;
}
function stream_gets()
{
$this-pointer=$this-data_length;
return $this-data;
}
}
file_register_wrapper('variable', 'variable_stream') or die('Failed to
register protocol');
$content='foo'.chr(0).'bar';
echo strlen( file_get_contents ('variable://'.$content) );
?
results a length of 3 instead of 7.
Also when stream_read results more bytes as file_get_contents or another
command
requested, php results a segfault.
here the backtrace:
Program received signal SIGSEGV, Segmentation fault.

[PHP-DEV] Predefined Classes in Zend2
Hi,
is it possible that predefined classes no longer working
in zend2 engine ?
eg:
?php
$chk= new __PHP_Incomplete_Class;
var_dump($chk);
?
in zend1:
the incomplete message is written:
Fatal error: The script tried to execute a method or access ...
correct, but in zend2:
object(__PHP_Incomplete_Class)(0) {}
also the same example with ming:
?php
$dir= new SWFMovie;
var_dump($dir);
?
in zend1:
object(swfmovie)(1) {
[movie]=
resource(2) of type (SWFMovie)
}
in zend2:
object(swfmovie)(0) {}
and the PHP_FUNCTION(swfmorph_init) in ming.c is definitively not longer
calling in zend2.
A bug or a new behavior in zend 2?
Regards,
Steve

[PHP-DEV] zend_hash_find,Z_OBJPROP and Zend2
Hi,
i have problems with ming and the new zend2engine.
Is it not possible to detect zend objects about the zend_hash_find
method with the new zend engine?
e.g.:
in ming.c SWFgetProperty() zend_hash_find cant locate the objects which
is
defined with $movie=new SWFMovie(); (swfmovie_init())
ming.c line 138
if (zend_hash_find(Z_OBJPROP_P(id), name, namelen+1, (void **)tmp) ==

[2001-11-26 11:26:29] [EMAIL PROTECTED]
Hi, i have found a very critical behavior with references under php.
The usage of references push in some cases the execution time extremly
higher.
I have written a small php script to explain the problem.
The main problem is, the longer the string the higher the execution
time, if you use a reference to the string.
?php
// a function with using a reference to a parameter
function with_reference ($stream, $loopcounter){
for ($x=0;$x $loopcounter; $x++){
$xyz=substr($stream,0,5); // i take only the first 5 characters
}
}
// the same function, but without a reference
function without_reference ($stream, $loopcounter){
for ($x=0;$x $loopcounter; $x++){
$xyz=substr($stream,0,5);
}
}
set_time_limit(60);
$loopcount=100; // only 100 function calls!
$streamsize=1048576; // 1MB, the longer the slower!!! Try 2MB.
// First, made a big string
for($x=0,$stream='';$x$streamsize;$x++,$stream.='x'){}
// Start function with a reference and measure start time
$tmp = explode(' ', microtime()); $measure['Start Reference']=(double)$tmp[0] +
(double)$tmp[1];
with_reference ($stream, $loopcount);
// Start function without a reference
$tmp = explode(' ', microtime()); $measure['Start Normal']=(double)$tmp[0] +
(double)$tmp[1];
without_reference ($stream, $loopcount);
// measure end time
$tmp = explode(' ', microtime()); $measure['End']=(double)$tmp[0] + (double)$tmp[1];
// subtract times
$with_ref_sec=$measure['Start Normal']-$measure['Start Reference'];
$without_ref_sec=$measure['End']-$measure['Start Normal'];
// output the times
echo tt;
echo Loopcount: $loopcountbr;
echo String size: $streamsizebr;
echo Time for function request \with_reference\nbsp;nbsp;nbsp;: ;
echo $with_ref_sec;
echo secsbr;
echo Time for function request \without_reference\: ;

From: [EMAIL PROTECTED]
Operating system: i686-pc-linux-gnu
PHP version: 4.0CVS-2001-11-21
PHP Bug Type: Unknown/Other Function
Bug description: wrong init with mcrypt_generic_init crashes php
Hi,
php crashes with libmcrypt (ive test it with 2.4.17) with the follow
php script.
The problem is the complete wrong initalising with mcrypt_generic_init.
The mcrypt_generic_init results -3 and mcrypt_generic crashes.
?php
$stream='Hello World!';
$td = @mcrypt_module_open (MCRYPT_ARCFOUR , '', MCRYPT_MODE_STREAM, '');
if ($td!=false){
$result=@mcrypt_generic_init ($td, false, false);
if ($result!=-1){
$stream = mcrypt_generic ($td, $stream);
mcrypt_generic_deinit ($td);
}
}
echo $stream;

[PHP-DEV] Bug #14082: unserialize have problems with negative numbers
From: [EMAIL PROTECTED]
Operating system: i686-pc-linux-gnu
PHP version: 4.0CVS-2001-11-16
PHP Bug Type: Variables related
Bug description: unserialize have problems with negative numbers
Hi,
i have detect two annoyingly bugs ;-) with serialize/unserialize.
The first bug indicate that unserialize can't work with negative
integer numbers.
The second problem brings php to crash! Unserialize
crash if you manipulate the count of expecting array
vars.
Bug 1:
?php
// Results: 'Warning: unserialize() failed at offset 13 of 39 bytes'
// and an empty result string, but not false
// because $foo['a'] is -1
error_reporting(2047);
$foo['a']=(int)-1;
$foo['b']=(string)'Paris';
$bar=serialize($foo);
if ($bar!=false){
echo $bar;
$nop=unserialize($bar);
print_r($nop);
}
?
---
Bug 2:
?php
// Result: PHP crash, because the array number is smaller than serialized
string
error_reporting(2047);
$ser_string='a:1:{s:1:a;i:1000;s:1:b;s:5:Paris;}';
// ^- actually 2
$unser_string=unserialize($ser_string);
?
I have tried to make a bt, but gdb notify no fault.
In debug mode some of my script warns with this:
Warning: String is not zero-terminated (source: ./zend_execute.c:449)
but i think that is another problem.

[PHP-DEV] Bug #12894 Updated: GD crashes PHP by using GD Format
ID: 12894
User updated by: [EMAIL PROTECTED]
Reported By: [EMAIL PROTECTED]
Old Status: Closed
Status: Open
Bug Type: GD related
Operating System: i686-pc-linux-gnu
PHP Version: 4.0.7-dev (latest CVS)
New Comment:
oops, i have post a message to this problem in php.dev under: GD seg fault on save
however, here is another code example to reproduce
the problem:
?php
$im_main=ImageCreateFromGD('2.gd');
ImageJPEG($im_main);
?
The problem is _not_ ImageJPEG! You can reproduce the problem also with
ImagePNG.
here is the backtrace:
Program received signal SIGSEGV, Segmentation fault.
gdImageJpegCtx (im=???, outfile=???, quality=???) at gd_jpeg.c:207
207 int val = im-tpixels[i][j];
(gdb) bt
#0 gdImageJpegCtx (im=???, outfile=???, quality=???) at gd_jpeg.c:207

you can download the '2.gd' file under:

No feedback and not enought information. If problem still
exists with latest CVS / GD reopen with required information.
[2001-08-30 22:36:22] [EMAIL PROTECTED]
I can not reproduce this. Does this happen with that
example script included in this report?
Does this crash happen with specific images? Where could
I get those images? What was the configure line like
for configuring PHP ?

[2001-08-27 08:50:44] [EMAIL PROTECTED]
Hi Jani,
here is the backtrace of the second script:
Program received signal SIGSEGV, Segmentation fault.
0x40411786 in gd_module_entry () from /usr/local/apache/current/libexec/libphp4.so
(gdb) bt
#0 0x40411786 in gd_module_entry () from /usr/local/apache/current/libexec/libphp4.so
(gdb)
the script fails only if you call ImagePNG after the ImageCreateFromGD.
Also ImageGD2 creates corrupted files, but this is another bug ...

I can't get your scripts to crash.
Could you please generate a GDB backtrace of the crash?
--Jani
[2001-08-22 12:13:54] [EMAIL PROTECTED]
Sorry, my submitted PHP Version was wrong. I mean 4.0.7-dev from the latest CVS.
The script crash under cvs version.

i guess it's timing-related (and definetly on the MySQL side)
what happens if you call
mysql ... -e select ID from footest order by rand() limit 8;
from command line several times instead of typing the query into the same client
multiple times?
my first guess would be that you get similar not-so-random results as the RAND()
result seems to be related to MySQL client runtime somehow ...
[2001-09-13 12:31:08] [EMAIL PROTECTED]
Hi,
i have found a mystic behavior with
MySQL and PHP.
The follow code describes a problem which i have
only observe in the combination between PHP and MySQL.
i have test it with PHP (406,407dev,408dev) and
MySQL (3.23.39-3.23.42) under suse-linux.
okay, lets go to the problem.
First make a simple table like:
// SQL-Dump
CREATE TABLE footest (
ID int(10) unsigned NOT NULL default '0',
KEY ID (ID)
) TYPE=MyISAM;
then push many rows in the table with increasing numbers!
?php
for ($i=1;$i=6;$i++){
mysql_query(insert into footest (ID) values($i));
}
?
okay, and now the miracle comes with this script:
?php
$result=mysql_query(select ID from footest order by rand() limit 8);
if ($result!=false) while ($tmp=mysql_fetch_assoc($result)){
echo $tmp['ID'].br;
}
else echo mysql_error();
?
i have attached 5 series from the little code:
Call 1: 52839,36271, 2555,42892,32471,13967,52990,27917

Call 5: 52735,36167, 2451,42788,32367,13863,52886,27813
you see the problem ? No, okay make the same test under
the mysql console.
Type:
select ID from footest order by rand() limit 8;
and mysql results really random rows. strange problem ;-)
i hope some developer have an idea, where the problem is, but
perhaps it is a mysql problem.

Without the splitsize, ...
?php

[PHP-DEV] Bug #12791: mcrypt doesnt work in 4.0.7 rc1 by this code
From: [EMAIL PROTECTED]
Operating system: i686-pc-linux-gnu
PHP version: 4.0CVS-2001-08-16
PHP Bug Type: mcrypt related
Bug description: mcrypt doesnt work in 4.0.7 rc1 by this code
Hi all,
mcrypt doesnt work in 4.0.7 with the following code:
the following code produce a
bWarning/b: Unknown list entry type in request shutdown (0) in
---PHP---
function cipherx_stream(){
$td = @mcrypt_module_open (MCRYPT_ARCFOUR , , MCRYPT_MODE_STREAM, );
}
$xyz=cipherx_stream();
---/PHP---
if you use this, PHP crashes:
---PHP---
function cipherx_stream(){
$td = @mcrypt_module_open (MCRYPT_ARCFOUR , , MCRYPT_MODE_STREAM, );
if ($td) mcrypt_generic_end ($td);
}
$xyz=cipherx_stream();
---/PHP---
PHP 4.0.6 work fine with the first code, but it crashes also
with the second :-(
Regards,

you can make it work in 4.0.6 by changing maxfactor from 8

curl_errno($ch) results a wrong error number and also curl_error($ch)
contains broken strings.
