Log: - Fix #50524, proc_open should respect cwd as it does on other
platforms

Agreed, it should behave the same.

No, a different behavior on Linux/BSD/OS X and Windows is not expected.
(and also between proc_open and the other program execution functions)

parameter.
Well,

If you really test the script yourself, you can see that getcwd() is
returning the correct working dir of the current PHP process, but
proc_open is using something else.
> then on Windows atleast
This have nothing to do with Windows. Only a wrong usage of
CreateProcess from the PHP developers in this case (lpCurrentDirectory
is not set to the value of getcwd).

This is expected, as also noted in the manual on the proc_open() page
for the $cwd parameter. If NULL is supplied to $cwd, then on Windows
atleast the directory where the PHP script interpreter is located is the
cwd.

Description:
------------
Hello,
each program execution function:
- exec()
- passthru()
- shell_exec()
- system()
- backtick operator
or popen() is using the current script (working) directory as working
directory for the command which is executed.
Only proc_open() is using a different directory:
- for apache2handler it the Apache ServerRoot
- for CGI it's the php-cgi.exe directory
- for FastCGI (mod_fgcid) it's also the php-cgi.exe directory
On *nix (mod_fcgid) the proc_open() working directory is as expected
also the script (working) directory.
Regards,
Carsten
Reproduce code:
---------------
<?php
header('Content-Type: text/plain');
echo "------getcwd()---------\n";
echo getcwd()."\n\n";
echo "\n\n-------popen()---------\n";
if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') {
$cmd = 'dir';
} else {
$cmd = 'ls';
}
$process = popen($cmd, 'r');
while (!feof($process)) {
echo fread($process, 80);
}
pclose($process);
echo "\n\n-------passthru()------\n";
passthru($cmd);
echo "\n\n------proc_open()------\n";
$descriptorspec = array(
0 => array('pipe', 'r'),
1 => array('pipe', 'w'),
2 => array('pipe', 'w')
);
$process = proc_open($cmd, $descriptorspec, $pipes);
while (!feof($pipes[1])) {
echo fread($pipes[1], 80);
}
fclose($pipes[0]);
fclose($pipes[1]);
fclose($pipes[2]);
proc_close($process);
?>
Expected result:
----------------
getcwd:
C:\Apache2.2\htdocs
3 times a directory listing of:
C:\Apache2.2\htdocs
Actual result:
--------------
getcwd:
C:\Apache2.2\htdocs
2 times (popen, passthru) a directory listing of:
C:\Apache2.2\htdocs
1 time (proc_open) a directory listing of:
apache2handler: C:\Apache2.2
or CGI/FastCGI: C:\PHP
