Subject: php5-cgi: fastcgi breaks __COMPILER_HALT_OFFSET__

Date: Thu, 24 Feb 2011 08:47:07 +0100

Package: php5-cgi
Version: 5.3.3-7
Severity: important
Tags: upstream


php code :
=======================================================
<?php
  print "offset:".__COMPILER_HALT_OFFSET__."==\n";

  __halt_compiler();

=======================================================

with fastcgi (using either libapache2-mod-fcgid or libapache2-mod-fastcgi) and suexec,
the first call works. If called again I get this error:
Notice: Use of undefined constant __COMPILER_HALT_OFFSET__ - assumed '__COMPILER_HALT_OFFSET__'
  in /var/www/dev4.sociatomdev.com/chroot/htdocs/test.php on line 2 offset:__COMPILER_HALT_OFFSET__== 


If I touch the php file, the script works again once.
If I kill fastcgi processes, the script also works again once.

script works fine with php as Apache module or cgi

It used to work with lenny

I tried the dotdeb package PHP 3.3.5. It's buggy as well :-(

obviously it's a memory leak. The following program should always print the same offset (last print before __halt_compiler() )
after few calls result become different.

<?php
  header("Content-type: text/plain");
  print "posix_getpid ".posix_getpid()."\n";
  if (!defined('__COMPILER_HALT_OFFSET__'))
      {
        print "not defined\n";
        $COMPILER_HALT_OFFSET=00000000;
        if ($COMPILER_HALT_OFFSET==0)
          {
            $fh = fopen(__FILE__, 'r+');
            $ok=0;

            $offset_file=-1;
            while(!$ok && ($line = fgets($fh)))
              {
                if ($offset_file<0 && preg_match("/^.*COMPILER_HALT_OFFSET=(00000000)/",$line,$matches,PREG_OFFSET_CAPTURE))
                  {
                    $offset_file=$pos+$matches[1][1];
                  }
                if (preg_match("/^.*(__halt_compiler\(\);)/",$line,$matches,PREG_OFFSET_CAPTURE))
                  {
                    $COMPILER_HALT_OFFSET=$pos+$matches[1][1]+18;
                    $ok=1;
                  }

                $pos=ftell($fh);
              }

            if (!$ok)
              {
                die("PHP 5.3 with fastcgi bug could not be corrected");
              }

            $computed_offset=sprintf("%08d",$COMPILER_HALT_OFFSET);
            print "computed_offset:".$computed_offset."\n";
            fseek($fh,$offset_file);
            fwrite($fh,sprintf("%08d",$COMPILER_HALT_OFFSET));
            fclose($fh);

          }
      }
    else
      $COMPILER_HALT_OFFSET=__COMPILER_HALT_OFFSET__;

  print "offset:".$COMPILER_HALT_OFFSET."==\n";

  __halt_compiler();abcd

Hi Pascal,

can you please try with PHP 5.4 from testing/unstable?  If it is still
broken, can you please report this bug to the bugs.php.net and report the
issue number back?
