Bug description:Inconsistent behavior of RecursiveDirectoryIterator to dot
files (. and ..)
Description:
------------
RecurisveDirectoryIterator skips dot files (. and ..) that appear on
the top of directory entries only. Since some file systems (e.g.: ext3,
FAT32)
doesn't sort directory entries, the behavior of RecursiveDirectoryIterator
is inconsistent.
RecursiveDirectoryIterator should either always skip dot files, or never
skip dot files. Otherwise many developer mistakenly assume that
RecurisveDirectoryIterator always skips dot files, and add a bug to their
programs.
----
(tested on ext3 file system)
# mkdir test
# cd test
# cat <<\EOF >test.php
<?php
echo __DIR__ . "\n";
print_r(array_keys(iterator_to_array(
new RecursiveDirectoryIterator(__DIR__)
)));
EOF
(use "-U" option not to sort)

(To ensure skippping dot files, construct the RecursiveDirectoryIterator
with SKIP_DOTS flag for now.)

new RecursiveDirectoryIterator(__DIR__, FilesystemIterator::SKIP_DOTS)
