Subject Re: Tomcat outputs php to stderr

How did you install your PHP 5.2.6?

Following the instructions from that "blog.taragana.com" page that
you mentioned, I should have found php5servlet.dll and phpsrvlt.jar
in pecl-5.2.6-Win32.zip.

Those files were there in 5.0.2, but they are absent in 5.2.6.

Also, I cannot find the sources for the servlet in the official 5.0.2
sources .tar.gz file, but some are available here:

http://cvsweb.php.net/viewvc.cgi/pecl/servlet/

Thus far:
1. How you installed them? Maybe there is some version mismatch.
2. Maybe there is some reason why those files are no more bundled
with 5.2.6.
3. If those are the sources - The servlet calls into native servlet.c,
and the rest is php-specific.

>From the sources (servlet.java, rev.1.21):
1. The code is experimental / alpha, so you should be prepared.
2. The servlet seems to be not thread-safe. It stores request, response
in its local fields.

IIRC, "implements javax.servlet.SingleThreadModel" must be added
to such a servlet to avoid concurrent calls (as mentioned in SRV.2.2
chapter of the Java Servlets spec 2.5)
.
Another way would be to mark the service() method of the servlet as
"synchronized" one.

It is hard to believe, that no one noticed these issues, but maybe
those are wrong sources, or I am missing something, or nobody
is using them and thus no one cares. All that is OK for experimental
code.

3. The writing of result is done in method servlet.write(String),
try {
response.getWriter().print(data);
} catch (IOException e) {
 e.printStackTrace(System.err);
}

If you are seeing the output text (as you mentioned), and not exceptions
and their stack traces, then maybe php just does not call this method
and writes all output to the stderr handle?  If so, then may be there were
some changes in the bridge / sapi of PHP, and the code / binaries are
not compatible...


All the above was just out of my curiosity, trying to find the
sources...

Best regards,
Konstantin Kolinko
