From: evert at rooftopsolutions dot nl
Operating system: OS X
PHP version: 5.5.9
Package: Streams related
Bug Type: Bug
Bug description:fpassthru broken
Description:
------------
fpassthru is broken for files > 2GB on 64bit systems.
Tested with OS X, but also getting reports from users of other operating
systems.
Likely there's an integer overflow issue.
Reference: http://evertpot.com/fpassthru-broken/
Test script:
---------------
# 5GB file
dd if=/dev/zero of=5gb bs=1024 count=5242880
php -r "fpassthru(fopen('5gb','r'));" > output_5gb
# 3GB file
dd if=/dev/zero of=3gb bs=1024 count=3145728
php -r "fpassthru(fopen('3gb','r'));" > output_3gb
# Comparing outputs
ls -lh
Expected result:
----------------
-rw-r--r-- 1 evert staff 3.0G 18 Feb 14:43 3gb
-rw-r--r-- 1 evert staff 5.0G 18 Feb 14:41 5gb
-rw-r--r-- 1 evert staff 3.0G 18 Feb 14:45 output_3gb
-rw-r--r-- 1 evert staff 5.0G 18 Feb 14:44 output_5gb
Actual result:
--------------
-rw-r--r-- 1 evert staff 3.0G 18 Feb 14:43 3gb
-rw-r--r-- 1 evert staff 5.0G 18 Feb 14:41 5gb
-rw-r--r-- 1 evert staff 0B 18 Feb 14:45 output_3gb
