Bug #79633 [Com]: readdir skips entries

Edit report at https://bugs.php.net/bug.php?id=79633&edit=1 ID: 79633 Comment by: keith at ksmith dot com Reported by: keith at ksmith dot com Summary: readdir skips entries Status: Open Type: Bug Package: Directory function related Operating System: Ubuntu 18.04, Others PHP Version: Irrelevant Block user comment: N Private report: N New Comment: This issue occurs direct, and over NFS. Tested with various versions of PHP 5 and 7, available with Debian, and on a Synology NAS. Extending to the character range [0-9,A-Z] for the folder names leaves out a number of other single letter named folders. Code indicates function calls php_stream_readdir which in turn calls php_stream_read, rather than the C language readdir function. I will likely hack up some code to use the 'C' library directly, I'm not sure why that call is so indirect/obfuscated.
