Bug #25429 copy() of stdin doesn't work any longer
Submitted: 2003-09-08 05:20 UTC Modified: 2003-09-09 20:58 UTC
From: devik at cdi dot cz Assigned: wez
Status: Closed Package: Filesystem function related
PHP Version: 4.3.3 OS: linux
Private report: No CVE-ID:
 [2003-09-08 05:20 UTC] devik at cdi dot cz
Description:
------------
copy("/dev/stdin","/tmp/xx"); was working in 4.0.6 but in
4.3.3 it results in empty file. When I ran strace then I see
fstat64(2) used on handle 4 which is dup(2)ed from handle 0.
It results to fs_size==0 and code in php_stream_copy_to_stream
(IIRC) hapily creates zero-sized file (immeditely - no wait for EOF).
With PHP fopen() it works as expected (it waits).

Reproduce code:
---------------
copy("/dev/stdin","/tmp/xx");

Expected result:
----------------
to stop on copy() and wait to EOF and then have input in /tmp/xx

Actual result:
--------------
copy() passes and /tmp/xx is zero-length file
