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
Dumping stat array 1...
...
["size"]=>
int(0)
...
["blocks"]=>
int(0)
Dumping stat array 2...
...
["size"]=>
int(45056)
...
["blocks"]=>
int(0)
