[Php-java-bridge-users] PhpCGIServlet, OCI8 and PATH environment

[<php...@li...>]

Hi,

I have the PHP/Java bridge installed and working in standalone mode with
Apache Tomcat.  The setup is:

* Tomcat 5.0.28 - handles all HTTP requests.  PHP runs as a CGI
sub-component.
* Java webapp - contains PHP files, JavaBridge.jar, php-servlet.jar and
servlet mappings in web.xml.
* PHP 5.1.2 - installed under C:\php5 (instead of WEB-INF/cgi in the
webapp)

All of this works correctly for a simple php.ini configuration, and
simple tests like phpinfo().

However, this breaks when I try to configure the php.ini file to load
the OCI8 extension, with the Oracle client installed under 
E:\oracle\ora92.  It looks like the OCI8 extension is not able to see
the Oracle libraries in E:\oracle\ora92\bin.  Note that the problem is
exclusive to the PHP/Java bridge -- PHP works from the command line with
OCI8.

I've tracked this down to a problem with the PATH being used for the PHP
cgi process (through Runtime.exec()).  In CGIServlet
$CGIEnvironment.setCGIEnvironment(), no "PATH" entry is created in the
environment and so, on Windows, a limited default seems to be used (C:
\php5;C:\WINNT;C:\WINNT\system32).

I created a simple patch to CGIServlet
$CGIEnvironment.setCGIEnvironment(), which passes through a system
property as the PATH into the environment:

            String systemPath = System.getProperty("system.path", "");
            envp.put("PATH", systemPath);

Combining this with an a java argument to set the system property
("-Dsystem.path=%PATH%") seems to fix the problem and the oci8 extension
works with the Oracle client DLLs.

But is there a better way of handling this?  Under linux I would use a
php-cgi.sh script to setup the path, but I don't know if there is a
similar way to handle this under Windows?  Or if I am missing something
in the Windows configuration.

Any suggestions would be greatly appreciated.

Thanks,
Gary

thank you very much for this problem report. I have
created a ticket for this, please see PR1481993:
http://sourceforge.net/tracker/index.php?func=detail&aid=1481993&group_id=117793&atid=679233

What about changing setCGIEnvironment to 

  protected Map getProcessEnvironment() {...}

so that JDK 1.4 users can override it using a custom
PhpCgiServlet or a custom PhpScriptEngine. The default
implementation of getProcessEnvironment() would simply
delegate to JDK1.5 System.getenv() using reflection:

+        try {
+          Method m = System.class.getMethod("getenv",
EMPTY_PARAM);
+          Map map = (Map) m.invoke(System.class,
EMPTY_ARG);
+          defaultEnv.putAll(map);
+      } catch (Exception e) {/*ignore*/}
+      return defaultEnv;

Please see PR1481993 for details.

I usually start php in FastCGI server mode outside of
java, using the command:

export X_JAVABRIDGE_OVERRIDE_HOSTS=/
php-cgi -b127.0.0.1:9667

AFAIK the FCGI server mode is currently not available
on windows, but this might change in the future; the
FCGI sapi is still being developed.

Thanks for the reply.

This looks like a good solution to me.  I had only been concerned about
the path, but it seems appropriate to have the rest of the environment
available as well.  This also seems like a good approach for JDK 1.4
compatibility, or in case you want to limit CGI access to the system
(you could override and supply a limited path, for example).

If you have a patch file, I would be happy to test it out.

Yes, the windows php-cgi.exe doesn't seem to recognize the "-b" flag.

Unfortunately my environment is currently limited to a windows server.
Hopefully that will change in the future as well. ;)

Let me know if there is anything else I can do to help.

Thanks,
Gary

Hi,

a preliminary patch (not tested) is here:
http://php-java-bridge.sourceforge.net/snaps/3.0.8.1/php-java-bridge_3.0.8_to_3.0.8.1.patch

If you have CVS access, you can get the version via:

cvs -d
:pserver:ano...@cv...:/cvsroot/php-java-bridge
co -rRelease-3-0-8 php-java-bridge


I will test the new code next week and attach version
3.0.8.1 at the end of your ticket.
