[PHP-BUG] Req #63655 [NEW]: check type functions - check type operators
From: sailormax at inbox dot lv Operating system: PHP version: 5.3.19 Package: Performance problem Bug Type: Feature/Change Request Bug description:check type functions - check type operators Description: Currently check type functions (is_string, is_int, is_float, is_bool, is_object, is_array) are functions. They are very often use in many engines. But because they are functions - they are very slow for engines. In result engine authors have to use faster alternatives (~2x faster) like: is_string = ((string)$var === $var) is_int= ((int)$var === $var) is_float = ((float)$var === $var) is_bool = ((bool)$var === $var) is_object = ((object)$var === $var) is_array = ((array)$var === $var) Can you compile this type of functions as operators? thank you. Test script: --- $ts = microtime(true); for ($i=0; $i5; $i++) $res = is_string($_GET); var_dump(microtime(true) - $ts); print br /br /; $ts = microtime(true); for ($i=0; $i5; $i++) $res = ((string)$_GET === $_GET); var_dump(microtime(true) - $ts); print br /br /; Expected result: equal time Actual result: -- is_string ~ 2x slower than ((string)$_GET === $_GET) -- Edit bug report at https://bugs.php.net/bug.php?id=63655edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63655r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63655r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63655r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63655r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63655r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63655r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63655r=needscript Try newer version: https://bugs.php.net/fix.php?id=63655r=oldversion Not developer issue:https://bugs.php.net/fix.php?id=63655r=support Expected behavior: https://bugs.php.net/fix.php?id=63655r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63655r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63655r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63655r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63655r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63655r=dst IIS Stability: https://bugs.php.net/fix.php?id=63655r=isapi Install GNU Sed:https://bugs.php.net/fix.php?id=63655r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63655r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63655r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63655r=mysqlcfg

Summary:Lack of error context with nested exceptions

Type: Bug
Package:Unknown/Other Function
Operating System: Redhat Linux

New Comment:
same problem with 5.2.x after 5.2.5;
I had calling unexist function in exception handler. In result PHP
returned empty page and didn't write any error in logs. Not very
comfortable debug scripts in such conditions... :/

Description:
In short, if you thrown an exception from within the exception handler,
you get an uninformative error message with no contextual information.
It makes sense for this case to be a fatal error. We don't want to get
recursive throwing of exceptions and spiral to our death.
If you create an exception in the error handler without throwing it, it
has the correct info about where it was created. This is enough to
figure out where the error is coming from. It is at least far more
informative and gives you a starting place in a potentially complex code
base.
From my quick look at the code in Zend/zend_exceptions.c:94 where this
originates. It looks like the exception is there, and that would have
file/line num info.
Test script:
---
?php
set_exception_handler(exceptionHandler);
function exceptionHandler($excp)
{
throw new Exception(Error 2);
}
throw new Exception(Error 1);
Expected result:
Fatal Error: Error 2
Actual result:
--
Fatal error: Exception thrown without a stack frame in Unknown on line 0

#26771 [Com]: register_tick_funtions crash under threaded webservers
ID: 26771 Comment by: sailormax at inbox dot lv Reported By: info at tphnet dot com Status: Suspended Bug Type: *General Issues Operating System: * (ZTS only!) PHP Version: 6CVS, 5CVS, 4CVS Assigned To: rasmus New Comment: -- 3 years later -- PHP 5.2.0 (Apache2 handler) Apache 2.2.3 problem still here... and broken example (16-3) in help without any marks still here :) http://lv.php.net/manual/en/control-structures.declare.php Previous Comments: [2006-07-04 16:10:07] astronouth7303 at gmail dot com I've seen this bug on my set up as well. PHP 5.0.5 (Apache2 handler) Apache 2.0.55 Windows XP Pro v2002 SP2 (Windows NT 5.1 build 2600) The way I've figured it out is that if the tick function (registered by register_tick_function()) is called (N ticks have gone by), PHP/Apache crash. I'm not sure if this applies to everyone, but I also found that the Apache child process would not fully initialize after crashing. The new child process had to be killed manually, and the next child would finish initialization. [2006-04-18 20:10:49] motin at demomusic dot nu Noticed typo: Of course I meant 83 instead of 85. Also, too bad the post got screwed up, with doubled linebreaks in the example. [2006-04-18 19:58:56] motin at demomusic dot nu I do not have the skills to dig into the appropriate code, unfortunately. Possible workarounds: 1. Switch to Linux :) - If not wholly, do it by installing the free VMWare GSX Server and build up a server in there. Recommended because learning how to configure a Linux server is a great skill that all php-developers will gain on learning. 2. PHP in cgi-mode is not affected, only php when running as an apache_module. I wanted to use ticks only for debugging purposes, and what I did while on windows was to configure httpd.conf so that accessing my site on port 85 would run php in cgi-mode instead of as a module. Here is a simplified section of my httpd.conf for this: # Make sure no modules are loaded before VirtualHost-containers Listen 80 VirtualHost *:80 LoadFile /Dev/Server/php5/php5apache2.dll LoadModule php5_module /Dev/Server/php5/php5apache2.dll AddType application/x-httpd-php .php DocumentRoot /path ServerName localhost IfModule mod_php5.c php_admin_value display_errors 0 php_admin_value error_reporting 7 /IfModule /VirtualHost Listen 83 VirtualHost *:83 RemoveType .php Action php5-script /php/php-cgi.exe AddHandler php5-script .php DocumentRoot /path ServerName localhost # php_admin_value and php_value is not possible in cgi-mode. These values has to be entered in php.ini # This section I found when trying to configure this myself back then. Do not know if it is needed # Directory /path/to/php/ # Options +ExecCGI +FollowSymLinks # AllowOverride None # Order allow,deny # Allow from all # /Directory /VirtualHost Cheers! [2005-08-10 20:02:22] [EMAIL PROTECTED] You are probably right that the tick stuff is broken in ZTS mode. But I doubt anybody is all that interested in fixing it as it is a very fringe feature in a very fringe environment. You can always hope, but chances are you will need to dig into the code yourself and send us a patch to get any movement on this. [2004-01-02 19:23:33] info at tphnet dot com Description: While searching the bug database I found some similar problems, but all were suspended. I wasn't sure if it was useful to reply to one of those (Most recent one: http://bugs.php.net/bug.php?id=26286). Well anyways, here goes: The problem is very simple. I just copy and paste the 'tick' example from the php manual into a new php file an try to execute it on my apache2 server. The apache child process crashes, restarts, crashes, restarts and eventually just stops restarting. When I comment out the line 'register_tick_function', everyting works just fine. Also, when I start the file from the CLI version of PHP it is executed without any problems. I'm using PHP 4.3.4 and Apache 2.0.48 (in conjunction with php4apache2.dll).
