php-java-bridge-users Mailing List for PHP/Java Bridge (Page 83)

Hi Jost, I am not sure if my previous e-mail arrived. Its about the
error on line 1943, which does not seem to be missing initialization
but rather a wrong object name:


---------- Forwarded message ----------

Subject: Re: [Php-java-bridge-users] Strict Standards: warning on line 1943
To: php...@li...


Hi Jost,

 I set
 public $__cancelProxyCreationTag = 0;
 on line 1824; but it did not fix the error. I still see:
 --------------

Strict Standards: Creating default object from empty value in
 lib\Java.inc on line 1943
 --------------

 I think the problem is $result. Shouldn't line
 1943: $result->__cancelProxyCreationTag = ++$client->cancelProxyCreationTag;
 be:
 1943: $this->__cancelProxyCreationTag = ++$client->cancelProxyCreationTag;
 ?

 Regards,


 Antonio

  Do you mean that each Java class that is instantiated in PHP should implements Serializable
   
  class MyClass implements java.io.Serializable{...}
   
  or it is necessary only for those classes that are used across two scripts (i.e. that are used in session)?

the PHP/Java Bridge web application is marked distributable. Therefore all value objects must
implement the java.io.Serializable interface.

Hi,

I was able to reproduce this problem with Apache .2.8 (.2.6 doesn't have this problem).

Since Apache 2.2.8 the PHP MINIT() is called exactly once and the MSHUTDOWN() function is called
more than once, violating the PHP module contract.

In other words: PHP does not work anymore with Apache 2.2.8. Please use some other HTTP server or
some other SAPI, for example FastCGI.

I have the gut feeling that this is a long-time PHP bug; they've probably implemented the wrong
callback. PHP's MSHUTDOWN() shouldn't be called for each child, it should be called when the whole
HTTP server terminates. 


A quick workaround is to store the PID in the MINIT() function (see java.c) and ignore any
MSHUTDOWN() where getpid() != pid. Something like this:

In java.c:
int pid;
MINIT()
{
  pid = getpid();
  ...
}

MSHUTDOWN()
{
  if (getpid() != pid) return SUCCESS; // work around for a Apache 2.2.8 or PHP bug.
 ...
}


Note that all PHP modules have the same problem, so I suggest to file a bug report to either the
PHP or the Apache team.

Jost Boekemeier

hi,

ok, you are right whith the patch. this is probalbe bougous..

but look this code (bind.c)

static void wait_for_daemon(void) {

 ....removed...

  for(i=0; i<2; i++) {
	struct timeval timeval = {2l, 0};
	if(select(1+EXT_GLOBAL(cfg)->err, &rfds, 0, 0, &timeval) > 0)
	  break;

	kill(EXT_GLOBAL(cfg)->cid, sig[i]);
  }	

  if((read(EXT_GLOBAL(cfg)->err, &err, sizeof err))!=sizeof err) err=0;
  //printf("VM terminated with code: %ld\n", err);
  close(EXT_GLOBAL(cfg)->err);
  EXT_GLOBAL(cfg)->err=0;
#else
  s_kill(0);					/* always -9 on windows */
#endif
}

what if select returns an error? you exit from loop and go ahead to
read, and this blocks if there are nothing to read. or?

anyway, i will make some test with debugging enabled...

some info:

java.so is loaded from php.ini with extension=java.so

i have only prefork mpm compiled, the apache configuration is a default
config with the following changes:

LoadModule php5_module modules/libphp5.so
AddType application/x-httpd-php .php

Include conf/extra/httpd-info.conf is switched on with ExtendedStatus On

Hi,

the patch is invalid, and I doubt that this is a PHP or PHP/Java Bridge issue.

Apache, when configured to use the prefork MPM, starts one Java process from the PHP MINIT() hook
and terminates it in the PHP MSHUTDOWN() hook. 

The MINIT() hook must be called *before* any worker child is spawned. And the MSHUTDOWN() hook
must be called *after* all childs have been terminated.

Any stress test, which might kill childs at various levels, must not touch the Java child spawned
from the MINIT() hook.

This means that either:

a) you have found a bug in Apache

b) this is a misconfiguration: for example java.so loaded from the PHP dl() function

c) this is a misconfiguration: for example mod_php.so running in a non PREFORK MPM.

Hi,

>   But serving PHP through tomcat could be much slower. 

I don't think so. I've seen web server tests which suggest that running PHP through FastCGI is
almost as efficient as through mod_php.


>   I also don't understand why mod_php and mod_jk both can not work?  PHP requests go through
> mod_php and JSP/servlet request goes through mod_jk to Tomcat.  Where is the conflict?

Depends on how you configure it. If you configure mod_jk to serve .jsp files only, your Java
classes may not be able to find their resources. If you configure it so serve anything except
.php, your PHP files may not be able to find their include (.inc) files anymore.

Jost Boekemeier

I guess you are refering "I want to use Apache/IIS as a front-end and tomcat as a back end. How do I enable PHP and JSP for all my applications?" section from FAQ.
   
  But serving PHP through tomcat could be much slower.  Can someone tell me impact of performance for serving PHP through Apache or Tomcat?
   
  I also don't understand why mod_php and mod_jk both can not work?  PHP requests go through mod_php and JSP/servlet request goes through mod_jk to Tomcat.  Where is the conflict?
   
  I hope to hear soon from someone.

hi,

since a few days i reported a bug to apache httpd.
https://issues.apache.org/bugzilla/show_bug.cgi?id=43966

after a backtrace seems this issue to be php-java-bridge related.

how to repeat:
install apache >=2.2.6 (i tested with 2.2.8)
install php 5.2.5 as module
install php-java-bridge >=4.0.1
enable php, javabridge
enable the apache server-status module
start apache

make a webserver stress wit ab
ab -c 100 -n 20000 http://yourserver/some.jpg
(some.jpg is any non php file)

open the server-status in your browser and reload it often.
after 4-5 seconds you will see many connections in
"C" Closing connetion status... (see apache bugreport)

The solution:
Please look at the attached patch.
i dont know what this line do, but if i remove it, everything works
fine. no more sticking "C" processes..

please analyze this patch.


thanks,

Hi, 
   
  I have the problem when executing the following two lines of code:
   
  $d2rq->mapAllMoodleData();
  redirect("start_here_page.php");
   
  mapAllMoodleData() is Java method that performs mapping of Moodle database to Sesame repository. As it is slow performance process it takes a while to execute this method (at least 1 minute). I have checked many times, this method is executed to the last line of code in Java application and there is no exceptions. However, the second line of code is never executed.
   
  Could you suggest me where should I look for the problem?

Hi,

No. :)

The JavaBridge is a normal J2EE application, which cannot control the amount of memory available
to Java. But the J2EE server or servlet engine can.

For tomcat the option is (example for Linux):

export JAVA_OPTS="-Xmx512M"

Hi,

I have been doing some stress-testing, sending simultaneously some
large files (2MB) to our Back-End through the JavaBridge, but they are
failing. Some of the errors I get back are:
protocol error: , Invalid document end at col 4. Check the back end
log for details.
or
protocol error: , Invalid document end at col 10. Check the back end
log for details.

In other cases it shows various errors like:
---------

errno=10053 An established connection was aborted by the software in
your host machine. in Java.inc on line 815

So it seems it is failing because of memory issues, right? Is there a
way to configure the amount of memory for the JavaBridge?

Thanks!

How do I find out if I have mode_php or not?  In my apache's httpd.conf file I found only the following reference about PHP:
   
  AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps

Either remove mod_php or remove mod_jk. You cannot have both.

Hi Jost,

I set
public $__cancelProxyCreationTag = 0;
on line 1824; but it did not fix the error. I still see:
--------------
Strict Standards: Creating default object from empty value in
lib\Java.inc on line 1943
--------------

I think the problem is $result. Shouldn't line
1943: $result->__cancelProxyCreationTag = ++$client->cancelProxyCreationTag;
rather be:
1943: $this->__cancelProxyCreationTag = ++$client->cancelProxyCreationTag;
?

Regards,


Antonio

Hi,

> $d2rqF=$session->get("d2rq");
> if(!$d2rqF)

the !$varName works only for PHP values. Please see your PHP documentation for details.
According to the PHP documentation you should use is_null().

Note that is_null() cannot test whether or not the containing object is the Java NULL object or
not. You must convert the Java object into a PHP value first, for example with java_values() or
with a (string) cast.

Hi,
   
  How can I check if instance of java object as java session variable exists. 
I have tried something like this:
   
  $session=java_session();   
$d2rqF=$session->get("d2rq");
if(!$d2rqF)
{
 $message=" d2rqFact does not exists";
   print_test_string($message, $table, $id);
}else{
 $message="d2rqFact already exists";
 print_test_string($message, $table, $id);
}
   
  But, I'm always get message "d2rqFact already exists" even if this variable is never created.
d2rq is an instance of Java object and I want to check if it is already created. If yes I will use it otherwise I will create it.
   
  Thanks,
Zoran

Hi,

according to php.net, support for PHP4 has been discontinued.

Altough PHP/Java Bridge version 4.x is still available for download, we cannot support this
anymore.


What about using some other software instead, for example XML-RPC?
