Description:
------------
When reading files from a stream wrapper, not all bytes are read.
Test script:
---------------
<?php
class lib {
public static $files= [];
private $bytes, $pos;
function stream_open($path, $mode, $options, $opened_path) {
$this->bytes= self::$files[$path];
$this->pos= 0;
$this->ino= crc32($path);
return true;
}
function stream_read($count) {
$chunk= substr($this->bytes, $this->pos, $count);
$this->pos+= strlen($chunk);
return $chunk;
}
function stream_eof() {
return $this->pos >= strlen($this->bytes);
}
function stream_close() {
$this->bytes= null;
}
function stream_stat() {
return [
'dev' => 3632233996,
'size' => strlen($this->bytes),
'ino' => $this->ino
];
}
function stream_set_option($option, $arg1, $arg2) {
return false;
}
}
$fill= str_repeat('.', $argv[1] ?? 0);
lib::$files['lib://test.php']= '<?php /* '.$fill.' */ function test() {
echo "Works!\n"; }';
stream_wrapper_register('lib', lib::class);
include('lib://test.php');
test();
Expected result:
----------------
$ /cygdrive/c/tools/php-7.3.6-nts-Win32-VC15-x64/php wrapper.php 8192
Works!
Actual result:
--------------
$ /cygdrive/c/tools/php-7.4snap-nts-windows-vc15-x64/php wrapper.php 8192
Warning: Unterminated comment starting line 1 in lib://test.php on line 1
