Various attributes are missing from $_SERVER

[jameshfisher]

I have created an automated test for this at: https://github.com/jameshfisher/hhvmbug

Install Vagrant and run test.sh.

At the end of this script it runs a diff that shows that HHVM omits the PHP_AUTH_PW and PHP_AUTH_USER keys from the $_SERVER variable when a client uses basic auth. These are the only keys that HHVM omits.

Having updated this test case to use PHP-FPM, it appears that the omission of PHP_AUTH_PW and PHP_AUTH_USER is actually due to the use of FastCGI, for some reason.

Still, there are differences between the $_SERVER variables. Specifically, HHVM omits all of these:

FCGI_ROLE, HOME, ORIG_SCRIPT_FILENAME, USER

and adds all of these:

HTTPS, REQUEST_START_TIME, SCRIPT_URI, SCRIPT_URL, THREAD_TYPE

I assume the missing variables at least are backwards-incompatible, so I'll leave this issue open. If anyone with better knowledge thinks these differences are deliberate or harmless, then feel free to close it.

Not exactly a dupe of #2646, but the fix we've got for that fixes this too.

On second thoughts, nope, those magic ones aren't fixed there.
