Bug #74252 [NEW]: Non-existent STDIN duplicates FD 0 instead of registering it as closed stream
From: kelunik
Operating system: Linux
PHP version: Irrelevant
Package: Streams related
Bug Type: Bug
Bug description:Non-existent STDIN duplicates FD 0 instead of registering it as closed stream
Description:
------------
If no STDIN exists, STDIN is still registered as FD 0 instead of a
closed stream. This results in scripts without STDIN reading from
/dev/urandom, because that's opened and just uses the next free FD.
Instead of duplicating the FD in
https://github.com/php/php-src/blob/16ae9f82e82e2aea5d7deaf8f9a9c825a56dfcc1/ext/standard/php_fopen_wrapper.c#L265
it should be registered as closed stream.
See also https://github.com/reactphp/stream/issues/81.
Test script:
---------------
php -r 'var_dump(!!fstat(STDIN));passthru("ls -o
/proc/".getmypid()."/fd");' <&-
Expected result:
----------------
STDIN should be a closed stream instead of /dev/urandom
Actual result:
--------------
STDIN is /dev/urandom
