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) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64060&edit=1
