Description:
------------
This applies to PHP 5.4.11 as well as 5.3.21.

Test ext/standard/tests/file/lstat_stat_variation7.phpt may incorrectly fail on delayed allocation file systems (in this case XFS on Linux).

Problem:
http://php.net/manual/en/function.stat.php
field 12 is "number of 512-byte blocks allocated"

The test does not fclose() the test file after writing to it, therefore zero 512-byte blocks are allocated even though the file size is 45056 bytes.

Fix:
Change lstat_stat_variation7.phpt from

// writing to an empty file
echo "*** Testing stat() on file after data is written in it ***\n";
$fh = fopen($file_name,"w");
$old_stat = stat($file_name);
clearstatcache();
fwrite($fh, str_repeat((binary)"Hello World", $old_stat['blksize']));
$new_stat = stat($file_name);

to

// writing to an empty file
echo "*** Testing stat() on file after data is written in it ***\n";
$fh = fopen($file_name,"w");
$old_stat = stat($file_name);
clearstatcache();
fwrite($fh, str_repeat((binary)"Hello World", $old_stat['blksize']));
fclose($fh);
$new_stat = stat($file_name);

and the test succeeds.


Test script:
---------------
File: ext/standard/tests/file/lstat_stat_variation7.php

To confirm, modify $file_name = "$file_path/lstat_stat_variation7.tmp"; to use a different file system and run ext/standard/tests/file/lstat_stat_variation7.sh.


Expected result:
----------------
Build of PHP 5.4.11

Test executed on ext2:

*** Testing stat() on file after data is written in it ***
bool(true)
bool(true)
bool(true)

--- Done ---


Actual result:
--------------
Same test executed on XFS:

*** Testing stat() on file after data is written in it ***
bool(true)
bool(true)
Error: stat1 is not lesser than stat2 at key value: 12
Error: stat1 is not lesser than stat2 at key value: blocks
