Description:
------------
Current implementation of Phar stub doesn't provide any way to disable impact of
Phar::interceptFileFuncs().
If you tried to run the test script for text file in the same folder
php my.phar test.txt:
File:test.txt
Path:C:\projects\PrimordialCode\php\glitches\open stat issue\test.txt
is_file:
is_readable:
file_exists:
file_get_contents:I'm the test text.
The same execution for test.php:
php my.phar test.php
File:test.php
Path:C:\projects\PrimordialCode\php\glitches\open stat issue\test.php
is_file:1
is_readable:1
file_exists:1
file_get_contents:<?php
$file = isset($argv[1]) ? $argv[1] : null;
if(is_null($file)) exit('Please specify a file');
echo "\n File:" . $file;
echo "\n Path:" . realpath($file);
echo "\n is_file:" . is_file($file);
echo "\n is_readable:" . is_readable($file);
echo "\n file_exists:" . file_exists($file);
echo "\n file_get_contents:" . file_get_contents($file);
The issue caused by https://github.com/php/php-src/blob/master/ext/phar/stub.h
E.g. line with Phar::interceptFileFuncs() hardcoded call:
static const char newstub1_0[] = "';\n\nif (in_array('phar',
stream_get_wrappers()) && class_exists('Phar', 0))
{\nPhar::interceptFileFuncs();\n ....
Test script:
---------------
<?php // Script to build phar
$phar = new Phar("my.phar",0, "my.phar");
$phar["test.php"] = file_get_contents("test.php");
$phar->setStub($phar->createDefaultStub("test.php"));
// Content of test.php
<?php
$file = isset($argv[1]) ? $argv[1] : null;
if(is_null($file)) exit('Please specify a file');
echo "\n File:" . $file;
echo "\n Path:" . realpath($file);
echo "\n is_file:" . is_file($file);
echo "\n is_readable:" . is_readable($file);
echo "\n file_exists:" . file_exists($file);
echo "\n file_get_contents:" . file_get_contents($file);
Expected result:
----------------
Provide a switch to disable/enabled the function call or phar header
customization.
Actual result:
--------------
Unexpected behavior of file lookup
