Summary: Phar::buildFromDirectory creates corrupt archives
for some specific contents
Status: Open
Type: Bug
Package: PHAR related
Operating System: Ubuntu 13.04, Windows 7
PHP Version: 5.3.x, 5.4.x, 5.5.x

This is a funny one. Seems to be because phar writes the archive this way:
<?php
// code code code
__HALT_COMPILER(); ?>METADATA_HEADER
Where METADATA_HEADER contains phar metadata, first 4 bytes being metadata
length. However, when phar reads the file, it checks if "__HALT_COMPILER(); ?>"
is followed by \r, and if there's \r it also looks for \n. Now imagine what
happens if metadata length is such that its first byte is 0x0D, but second byte
is not 0x0A? Phar file is not readable anymore.

I managed to recreate the issue and submitted a test case right here on GitHub:
https://github.com/php/php-src/pull/371

Re-tested with the latest PHP 5.5.0 release, still not working.

This one will result in the same corrupt phar archive:
$phar = new Phar("test.phar");
$iterator = new RecursiveIteratorIterator(new
RecursiveDirectoryIterator("/tmp/test/content", FilesystemIterator::SKIP_DOTS));
$phar->buildFromIterator($iterator, "/tmp/test/content");
$phar->compress(Phar::GZ);

Description:
------------
When creating a Phar archive with a very simple Phar::createFromDirectory()
call
(see test script) the generated archive is corrupt sometimes, depending on the
contents packed into the Phar.
I CAN PROVIDE THE TEST CONTENTS TO A DEVELOPER BUT NOT TO THE PUBLIC.
Opening the Phar will cause a Fatal error. Adding an additional empty file (see
test script) to the archive fixes the problem. Sometimes a second empty file
has
to be added, sometimes a third one.
Tested PHP versions:
- 5.3.26
- 5.4.16
- 5.5.0 RC3
Configure line (all versions):
'./configure'
'--prefix=/opt/php/bin/php-5.3.26'
'--with-gd'
'--with-ldap=/usr'
'--with-mysql'
'--with-mssql'
'--with-pdo-mysql'
'--with-pdo-dblib'
'--with-pdo-pgsql'
'--with-pgsql'
'--with-config-file-path=/opt/php/bin/php-5.3.26/etc'
'--enable-mbstring'
'--with-mcrypt'
'--with-openssl'
'--with-curl'
'--with-zlib'
'--with-libdir=lib/x86_64-linux-gnu'
'--with-jpeg-dir'
'--with-png-dir'
Test script:
---------------
// Corrupt
$phar = new Phar("test.phar");
$phar->buildFromDirectory("content");
$phar->compress(Phar::GZ);
// Working (only difference is adding the empty file)
$phar = new Phar("test.phar");
$phar->buildFromDirectory("content");
$phar->addFromString("an-empty-file", "");
$phar->compress(Phar::GZ);
Expected result:
----------------
Working phar archive which can be opened with "new Phar('test.phar')".
Actual result:
--------------
Fatal error: Uncaught exception 'UnexpectedValueException' with message
'internal
corruption of phar "/tmp/test/test.phar" (truncated manifest at stub end)'
