RE: [Php-java-bridge-users] Is it possible to release Java memory inside a PHP request?

Php 4 does not release allocated handles. If you call:

for($i=0; $i<100000; $i++) $s=new String("123");

php 4 creates 100000 string objects which will be
released by the bridge when the script terminates.

Since PHP5 each string instance is released
immediately, so the VM cannot run out of memory, even
if the script runs forever.


So I would recommend to upgrate to the latest stable
php5 version, which is php 5.0.5, and to use PHP/Java
Bridge 2.0.8.

Please copy your .jar files to /usr/share/java or to
extension_dir/lib or to $JAVA_HOME/jre/lib/ext.

If you install your .jars in /usr/share/java or
extension_dir/lib, you can require them with:

  java_require("foo.jar;bar.jar");

If you copy them to $JAVA_HOME/jre/lib/ext, you must
restart the backend after installation.

have you already reported this to the PHP release
team?  If PHP5.1.1 is really ABI incompatible with
5.1.0, then this a serious bug which must be fixed
immediately!

(They cannot change the public API in the middle of a
release. If this is necessary, then they must adjust
the API_VERSION_NO and change the version number to
5.2).

I could reproduce this problem.  As a workaround
please change the java.servlet parameter to

I will fix this bug for version 3.0.0RC2, which will
be available tomorrow.  Thank you very much for

[Php-java-bridge-users] Problem about adding jar files to classpath on FC3

[Kun N. <hao...@gm...>]

Dear all,

Sorry to trouble you all.
But I've got the following problem.
My jre is jre1.4.2_10 which is installed with a rpm package download
from java.sun.com.
I've successfully installed php-java-brige on my FC3 with all the
default package bundled with FC3.
And now, I want to add some other jar files to my classpath.
But when I set java.classpath in my java.ini file.
The php-java server failed to start up.
Can someone be kind enough to tell me how to add some other jar files
to my classpath?

Thanks for reading and look forward to your reply.

Sincerely,
Kun

[Php-java-bridge-users] Is it possible to release Java memory inside a PHP request?

[Janno M. <jan...@tr...>]

Hi,

I'm using the bridge to make about 50000 calls to a Java method that takes 
ArrayList as a parameter (containing some Date, Integer and String objects) and 
returns a HashMap. My script causes java.lang.OutOfMemory error. Is there a way 
to destroy Java objects in PHP script and release memory? I've tried unsetting 
the objects in PHP and also calling garbage collector directly (via Runtime 
class) but it doesn't seem to help. I'm using PHP4 and JavaBridge version 
1.0.6a. Would newer versios work better for me? Any help greatly appreciated.

BR,
Janno

Re: [Php-java-bridge-users] Building with PHP 5.1.1

[<ced...@e-...>]

Hi,

I haven't tried on 5.1.0 since it has 5.1.1 was out to fix several major=20
issues with 5.1.0. BTW, I am building on a Linux platform. As I said, I=20
discovered that the zend_fetch_debug_stacktrace method signature had=20
changed, and introduced a new parameter called "skip_last" :

ZEND_API void zend_fetch_debug_backtrace(zval *return_value, int skip_las=
t,int provide_object TSRMLS_DC)

Updating the bridge code line 1570 by adding this parameter did the trick=
, and I was able to build the bridge.

My problem now is about that 403 error with Tomcat when trying to do "PUT=
" on the servlet...

Hi Cedric,

do you have the same problems with 5.1.0, too?

I am currently testing 3.0.0 and 2.0.9 (which is 2.0.8
+ one bugfix) against 5.1.0, and it compiled fine. --
There was one serialization problem, but that turned
out to be a problem with the backend running in the
GNU jvm.

So if there's an issue with 5.1.1, then I think
there's something broken with 5.1.1. 

BTW: I usually test the windows version on wine
because this catches most of the windows related
issues. Since 5.1.0 php runs scripts much faster but
crashes during shutdown. This happens all the time, so
I don't think it's related to our code.  Maybe it is
possible to wait until Fedora Core 5 is available next
year. After some time these problems usually
disappear. :)

RE: [Php-java-bridge-users] Building with PHP 5.1.1

[<ced...@e-...>]

Ok, it seems the zend_fetch_debug_backtrace method signature has changed =
:
it takes one more argument.

ZEND_API void zend_fetch_debug_backtrace(zval *return_value, int =
skip_last,
int provide_object TSRMLS_DC)

I changed the corresponding line to the following :

zend_fetch_debug_backtrace(trace, 0, 0 TSRMLS_CC);

And it builds correctly. Now I'm facing another problem : the bridge =
version
3 does not seem to work with my Tomcat server as it did. I'm getting
"protocol violation" errors...

Re: [Php-java-bridge-users] bug in 2.0.8 with PHP5 iterator interface.

[Jost B. <jos...@ya...>]

Hi Alan,

I should have looked at this more carefully. This is
indeed a bug in the PHP/Java Bridge code: when the
list is empty, we may pass an uninitialized object to
php.  After that php may or may not crash, depending
on the malloc() strategy and on the iterator
implementation.

I will prepare version 2.0.9 next week, which fixes
this bug.

In the meantime please add the following two lines to
the get_iterator() in java.c:

@@ -1237,6 +1237,8 @@
   (*jenv)->writeInvokeEnd(jenv);
   if(Z_BVAL_P(presult)) 
 	init_current_data(iterator TSRMLS_CC);
+  else
+	iterator->current_object = NULL;
 
   zval_ptr_dtor((zval**)&presult);


Thank you very much for this bug report!

Jost Boekemeier

Re: [Php-java-bridge-users] bug in 2.0.8 with PHP5 iterator interface?

[Alan P. <api...@ma...>]

Thanks for the note.

However, I am still a bit confused...

I can confirm that switch from:

foreach ($javaResultList as $i)

to

foreach (java_values($javaResultList) as $i)

Does indeed avoid the bug. BTW I am on PHP 5.0.4...

However, if the zend iterator interface is broken on empty lists,  
then converting the list from JAVA to PHP array shouldn't fix the  
problem, but it does...

The difference is that if it's a java object, it's calling the  
zend_iterator from the bridge, otherwise calling the internal zend  
iterator. In both cases the list is empty and thus *should* crash if  
the zend iterators are externally calling "currentKey" on empty arrays.

I certainly agree that it's nonsense for "currentKey" to get called  
on the iterator when hasMore returns false.

Now I know that the Iterator interface hierarchy is big, so maybe the  
iterator type used on the PHP array is different from the one used /  
implemented by the bridge?

It just seems that if the bug is that empty arrays cause crashes,  
then the bug shouldn't go away by converting the list to a PHP array.

Maybe that you've "mixed" the hashmap and array iterators into a  
single one is screwing it up? I don't know too much about the zend  
iterator internals, just trying to make sense of the bug.

See what I mean?

Hi Alan,

it seems that since version 5.0.5 the zend interator
advances one element too far when the list is empty. 
According to your log you have passed an empty list.
The zend iterator asks us "hasMore", we return false.
After that it asks for the current key(!?!) which
doesn't exist, of course, we have returned false!

What follows is that php becomes confused and crashes:
The currentKey() that java returns isn't valid and php
tries to examine the key len, which may or may not
result in a segmentation fault and a php crash.

I will check the details tomorrow evening, in the
meantime please use the following workaround:

$php_array = java_values($javaList);
// now you can iterate over php_array which checks for

// the above invalid condition.

Or please downgrade to php 5.0.3 or below. :((


Regards,
Jost Boekemeier

P.S.: My plan was to drop PHP4 support in PHP/Java
Bridge Version 3.0. I don't think this is possible
considering that every new php 5 release introduces
new bugs. (Since php 5.1 even the serialization
doesn't work anymore, which worked in the php5.1 pre
betas)...

Please follow the INSTALL instructions as close as
possible.


If you're stuck please open a ticket, please use:
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233

Please attach the output of the config.status,

If there are compilation or configuration issues on
IA86 or AMD64 Linux, Windows >= Win95, FreeBSD or
Sparc/Solaris with Sun or IBM JDK please first check
the INSTALL document again and follow the steps as
close as possible before submitting a problem report.
We know that the bridge compiles and runs without
problems on these platforms.


For other platforms please go ahead and open a problem
report right away: There are known issues with the
Macintosh JVM and with GNU JVM[1]. We're currently
trying to find a workaround for these problems.

RE: [Php-java-bridge-users] Sharing sessions apache / tomcat

Do you use the mod_jk adapter (see "Example#1:
Apache/IIS/mod_jk connector" in the NEWS) or do you
share the http server document root with the servlet
engine's webapps directory (see Example#2 "Example: a
shared document directory" in NEWS)?
(-> http://php-java-bridge.sourceforge.net/NEWS)


> I pass elements in the session from php to java and
> it works fine.

Depending on your setup the cookie PATH is "/", which
is okay for a single-user setup.


> But when I return to the php I loose my elements.

If you check your cookies you'll probably see two
cookies, one with PATH=/JavaBridge and one with
PATH=/. Or you'll see only one cookie with PATH=/.
Which means that you cannot access the /JavaBridge
cookie anymore.  This behaviour is intentional:

In a multi-user setup script userA/sessionSharing.php
should not be able to share the session values with
script userB/sessionSharing.php.

If you don't care about the PATH, I suggest to install
the JavaBridge.war without a context (i.e. as context
"/"). After that you need to change the java.servlet
setting from "/JavaBridge/PhpJavaServlet" to:

  java.servlet = "/PhpJavaServlet"


> When I look at the cookie (JsessionID) I have the

Yes, but what about the PATH?

[Php-java-bridge-users] Sharing sessions apache / tomcat

[MICHET S. <syl...@ca...>]

Hello,

=20

I am trying to share sessions between php and java.

The installation of the javabridge.war works fine for the session
sharing works fine.

By the way thank your for your programming !

=20

Now I would like my php repository to be independent from the tomcat
repository.

I pass elements in the session from php to java and it works fine.

But when I return to the php I loose my elements.

=20

When I look at the cookie (JsessionID) I have the same cookie from php
to java.

But when I go back to the php file, a new cookie is created.

In advance thank you for your help.

I'm using gcc 3.3.5, php 4.3.11 and gnu make 3.80.

How can I compile the php-java-bridge?

Re: [Php-java-bridge-users] bug in 2.0.8 with PHP5 iterator interface?

[Alan P. <api...@ma...>]

I am not sure which component dies. There are no messages left in any  
log files (apache's error_log, /var/run/php-java-bridge.log, etc).

I have posted the bug, and added some more notes from research today.

Which component dies, the java.so or the java backend?

We know that there are issues with Apple's jdk1.4,
which cannot run our bench.php for more than one hour.
But this is a known issue with the apple JVM, the
crash is reproduceable using a pure java test. (It
seems to be a combination of the class gc and the
apple JIT). Which JVM do you use?

Can you please open a ticket for this and attach the
java trace log at the end of the ticket?

[Php-java-bridge-users] bug in 2.0.8 with PHP5 iterator interface?

[Alan P. <api...@ma...>]

Hello-

I've gotten things working, but sometimes the bridge seems to die mid- 
request. The server doesn't have a chance to answer, and no data is  
returned.

I've narrowed it down to the iterator interface over returned Java  
arrays. Here's the offending code:

                 $facets = $facetGenerator->getList($this->value,  
$this->maxRows, $this->sortByFrequency, $this->maxHits);
                 foreach ($facets as $facet) {
			// does nothing, but still crashes
                 }

getList() returns an array of java objects:

public AttributeValue[] getList(java.lang.String attribute_id,
                                 int maxRows,
                                 boolean sortByFrequency,
                                 int maxHits)
                          throws java.io.IOException,
                                 NotFoundException

Here's a tcpflow dump of the bridge comm for that request:

127.000.000.001.09267-127.000.000.001.56795: <O v="" i="46194528"/>

So it seems to me it's somehow getting killed during the iterator.

Now, it doesn't ALWAYS fail. Sometimes it works. I think maybe only  
when EMPTY lists are returned it fails, but I am not positive. Maybe  
that will help you?

Thanks in advance for any thoughts. Please respond to me as well  
directly as I am not currently on the mailing list.

Thanks,
Alan

Hi Christoper,

Which exceptions do you get?

I've just tested it on SF, and it worked, at least
HelloWorld.php, HelloWorld2 is difficult to test here.

It accesses a web server[1] which should be able to
run php scripts.

The web server must be on the same machine, though, it
isn't a good idea to allow users to allocate and call
php instances from remote servers. In the current
snapshot you can set   
System.setProperty("php.java.bridge.promiscuous",
"true") to allow this.

Jost Boekemeier

[1} i.e. Apache/IIS running php as a module or a
Tomcat or a java AS running PHP as a FastCGI or CGI
binary.

[Php-java-bridge-users] Got things working on OS X

[Alan P. <api...@ma...>]

I just got things working on my Mac OS X 10.4.3 box and figured I'd  
post my notes for posterity. I have a pretty common setup and ran  
into a few hiccups so hopefully this will save some others some time!

Version used: php-java-bridge-2.0.8
PHP Version: 5.0.4 installed via fink

Fink Setup
Using libapache2-ssl-mod-php5 / php5-apache2-ssl
Had to install php5-apache2-ssl-dev to get a working phpize command

Build php-java-bridge as directed. Worked very well. Use --with-java= 
$JAVA_HOME to compile against Mac's JVM.

The php-java-bridge script expects the "php" on the PATH to be the  
desired php. You may need to update the PHP path to /sw/bin/php5

PHP Setup
php.ini setup:

extension = /sw/lib/php5/20041030/java.so
[java]
java.log_level="3"
java.log_file="/var/log/php-java-bridge.log"
java.hosts=localhost:9267
#java.socketname="/var/run/.php-java-bridge_socket"

NOTE: the default for php-java-bridge is to use unix sockets  
(java.socketname), but this doesn't work on Mac OS X. Switch to TCP  
by commenting out java.socketname and adding the java.hosts line.

Copy php-java-bridge shell script to /usr/sbin/ and run it.

That's it! After that, the test.php script worked.

Enjoy,
Alan

RE: [Php-java-bridge-users] php_closure, java_closure, and javax.scripts

[Jost B. <jos...@ya...>]

Hi Christopher,

The examples folder now contains a java-server-faces
example. If you use JSF as your framework, the code
should work "as is". For other frameworks you need to
write a custom ScriptEngine, ScriptContext and
Context, please see the PhpFacesScriptContext,
PhpFacesScriptContextManager, PhpFacesScriptEngine and
PhpFacesContext classes for a template.


> May I attack by bits and pieces using php_closure
> and java_enclosure ?

Yes. Basically you open a URLConnection to the php
instance running in the frontend (Apache/IIS/Servlet
Engine) which triggers the: 
java_context()->call(java_closure()); After that your
java code can call the functions or methods in
allocated PHP closure.


> If so, where may I download the javax.scripts

The script-api.jar is now in the unsupported folder, I
will check in the source, too.  The code was written
and (C) by Sanka Samaranayake (sa...@op...),
licensed under the Apache License.

The source is now in the php-java-bridge/server/javax
folder.  

A snapshot of the current Version 3 source code is
available at:

http://sourceforge.net/project/showfiles.php?group_id=117793&package_id=170256


I will check that code into our CVS as soon as
possible, but currently the SF cvs service seems to be
broken, it rejects everything I commit. In the
meantime please use the source snapshot above.


Regards,
Jost Boekemeier
