Hi,
Firstly many thanks to Tony, Hanne & Dmrity for providing all the required
information which help me analyze various failure on MacOS X.
The analysis is bit lengthier, my apologies for the lengthy note. Appreciate
any feedback and comment, that would be helpful in analyzing the failure on
other OS, which is in progress.
I do not have a MacOS X system, but tried to put the analysis, please feel
free to correct me if i am wrong. Below analysis contains the following :
The failure out difference as generated by run-test.php
Analysis of failure,
A sample testcode which can be run to verify the failure/behavior &
Expected output on RHEL 5.
Following testcases are failing and have been analyzed :
Test filesize() function: usage variations
[ext/standard/tests/file/filesize_variation.phpt]
Test popen() and pclose function: error conditions
[ext/standard/tests/file/popen_pclose_error.phpt]
Test readlink() and realpath functions: basic functionality
[ext/standard/tests/file/readlink_realpath_basic.phpt]
Test readlink() and realpath() functions: error conditions
[ext/standard/tests/file/readlink_realpath_error.phpt]
Test readlink() and realpath() functions: usage variation
[ext/standard/tests/file/readlink_realpath_variation.phpt]
Test symlink(), linkinfo(), link() and is_link() functions : error
conditions
[ext/standard/tests/file/symlink_link_linkinfo_is_link_error.phpt]
Test symlink(), linkinfo(), link() and is_link() functions : usage
variations
[ext/standard/tests/file/symlink_link_linkinfo_is_link_variation.phpt]
================================================================================
Failure in filesize_variation.phpt
================================================================================
Output lines indicating failure :
---------------------------------
016+ int(68)
016- int(4096)
018+ int(102)
018- int(4096)
021+ int(102)
022+ int(68)

024+ int(102)
025+ int(102)
024- int(4096)
025- int(4096)
Explanation:
------------
There is a difference in the size of a dir when created. On Linux its is
4096 by default but
on MacOS its 68 and then changes when a new file/subdir is created inside
the dir. I suggest that we
have seperate testcase for MacOs or just do the check for %d or %i in place
of size.
Here is the sample code to reproduce this:
<?php
$filepath = dirname(__FILE__);
// create dir and check size
mkdir(dirname(__FILE__)."/temp");
var_dump( filesize($filepath."/temp") );
mkdir($filepath."/temp/subdir");
var_dump( filesize($filepath."/temp/subdir") );
// remove temp dir
rmdir( $filepath."/temp/subdir");
rmdir( $filepath."/temp");
?>
Expected result on Linux ( RHEL 5 ):
-----------------------------------
int(4096)
int(4096)
================================================================================
Failure in popen_pclose_error.phpt
================================================================================
Output lines indicating failure :
---------------------------------
009+ Warning: popen(abc.txt,rw): Inappropriate ioctl for device in
/private/var/root/tony/php-src_5_2/ext/standard/tests/file/popen_pclose_error.php
on line 13
009- Warning: popen(abc.txt,rw): Invalid argument in %s on line %d
Explanation:
------------
The behavior of popen() is expected to be saying "Invalid argument ...." but
looks like it
tried to proceed with the given wrong input and finally fails. I think this
looks like a bug,
If you agree I'll raise bugzilla.
Code for reproducing the error:
<?php
var_dump( popen("abc", "rw") ); // with invalid mode argument
?>
Expected result on Linux ( RHEL 5 ):
-----------------------------------
Warning: popen(abc.txt,rw): Invalid argument in %s on line %d

"/private/var/root/tony/php-src_5_2/ext/standard/tests/file/readlink_realpath_basic/readlink_realpath_basic.tmp"
067- bool(false)
Explanation:
------------
The failure on line number 35 is coming from realpath().
The expected output is bool(false) because given path is invalid and
nonexistent.
I think this looks like a bug, If you agree I'll raise bugzilla
The failure on line number 41 & 67, The given path is
correct but since it end with a forward slash, it should be treated as dir
and hence non-existing
The function seems to not behave correctly. I think this looks like a bug,
If you agree I'll raise bugzilla.
The failure on line number 39, is coming from readlink().
The given path exists and ends with a slash, hence it should be treated as
directory (as it does on Linux)
but here the error indicates that its an invalid argument. On linux it
indicates that "its Not an directory".
I think the behavior should be consistent, If you agree I'll raise bugzilla.
Code to reproduce the error:
<?php
// realpath with invalid and nonexistent path
$path = dirname(_FILE__)."/..".basename(__FILE__);
echo $path."\n";
var_dump( realpath($path) );
$path = __FILE_."/"; // correct path ending with slash
echo $path."\n";
var_dump( realpath($path) );
// readlink with invalid path
$file = FILE;
$link = dirname(__FILE__)."/mylink.tmp";
var_dump( symlink($file, $link) );
var_dump( readlink($link."/") ); // link path ending with slash
// remove temp link
unlink($link);
?>
Expected result on Linux ( RHEL 5 ):
-----------------------------------
/workdir/test/fail/..realpath.php
bool(false)
/workdir/test/fail/realpath.php/
bool(false)
bool(true)
Warning: readlink(): No such file or directory in %s on line %d

Output lines indicating failure :
---------------------------------
032+ string(77)
"/private/var/root/tony/php-src_5_2/ext/standard/tests/file/realpath_error.tmp"
032- bool(false)
Explanation:
------------
The failure is coming from realpath with nonexistent file. The expected
output should be bool(false)
where as here the realpath returns the given input as output. I think this
looks like a bug,
If you agree I'll raise bugzilla
Code to re-produce the error:
<?php
var_dump( realpath( dirname(__FILE__)."/non_existent_file.tmp") );
?>
Expected result on Linux ( RHEL 5 ):
-----------------------------------
bool(false)
================================================================================
Failure in readlink_realpath_variation.phpt
================================================================================
Output lines indicating failure :

062- bool(false)
067+ string(36) "/private/var/root/tony/php-src_5_2/ "
067- bool(false)
Explanation:
------------
Here both the failure as coming because of " " and ' ' being passed to
realpath. The expected
behaviour should be bool(false) because given path doesn't exist. I think
this looks like a bug,
If you agree I'll raise bugzilla.
Code to reproduce the error:
<?php
var_dump( realpath(" ") );
var_dump( realpath(' ') );
?>
Expected result on Linux ( RHEL 5 ):

043+
Explanation:
------------
Here the failures( line no 9, 12 & 15) come from symlink() with first
argument supplied as : NULL, '' & false
The output on Linux and MacOS are not similar, I think the output should be
consistent. If you agree I'll raise bugzilla.
Code to reproduce the error:
<?php
$link = "./link.tmp";
var_dump( symlink(NULL, $link) );
var_dump( symlink('', $link) );
var_dump( symlink(false, $link) );
?>
Expected result on Linux ( RHEL 5 ):

Explanation:
------------
There two thing in the failure.
1. We see that the temp dir created by the tests already exists, may be not
cleaned
by previous tests ( i.e symlink_link_linkinfo_is_link.basic/error.phpt ).
The code pretty much there to
clean the dir created but looks like there could be problem, Please could
you run only these three tests and let us
know the result , in case of failure, pls provide diff file and output of
command "ls -l" on the dir where test is run
files are( please run the below sequnce only):
symlink_link_linkinfo_is_link_basic.phpt
symlink_link_linkinfo_is_link_error.phpt
symlink_link_linkinfo_is_link_variation.phpt
2. The other failure here is because of the directory permission is not
respected by symlink() and link command.
When the dir doesnot have permission to create a file inside it, the
symlink() and link() are still
creating the files in it. I think this looks like a bug, If you agree I'll
raise bugzilla
Code to reproduce this:
<?php
$dirname = dirname(_FILE_)."/temp";
mkdir($dirname);
$filename = __FILE;
// remove all permissions from dir
chmod($dirname, 0000);
// expected: false
var_dump( symlink($filename, "$dirname/non_existent_link.tmp") );
var_dump( linkinfo("$dirname/non_existent_link.tmp") );
var_dump( is_link("$dirname/non_existent_link.tmp") );
// clear the cache
clearstatcache();
rmdir($dirname);
?>
Expected result on Linux ( RHEL 5 ):
-----------------------------------
Warning: symlink(): Permission denied in %s on line %d
bool(false)
Warning: linkinfo(): Permission denied in %s on line %d
int(-1)
bool(false)
