Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows (zip): http://snaps.php.net/win32/php5.2-win32-latest.zip For Windows (installer): http://snaps.php.net/win32/php5.2-win32-installer-latest.msi Previous Comments: ------------------------------------------------------------------------ [2006-08-08 09:13:34] baldurien at bbnwn dot eu Here is a zip file with less file (in fact, just 4) : http://www.bbnwn.eu/works/stream-bugs-with-less-files.zip Simply run php -f bug.php ------------------------------------------------------------------------ [2006-08-02 12:00:58] baldurien at bbnwn dot eu Note : that BarInputStream.php and FooInputStream.php. ------------------------------------------------------------------------ [2006-08-02 12:00:17] baldurien at bbnwn dot eu For the content of archive, you should look for Stream/bug.php. For the number of files, no: 1. I tell you that a problem with require_once, hence, having all class and interface declared in the same file work as expected 2. I can go down to 4 files. Whose content is that (I'm not at home, today and tomorrow, so I can't send an archive file) : --- bug.php <?php abstract class Loader { protected abstract function loadFiles(); protected abstract function doSomething(); public final function load() { $this->loadFiles(); $this->doSomething(); } } class BarLoader extends Loader { protected function loadFiles() {require_once 'BarInputStream.php';} protected function doSomething() { $bar = new BarInputStream(); $bar->seek(1); } } class FooLoader extends Loader { protected function loadFiles() {require_once 'FooInputStream.php';} protected function doSomething() { $foo = new FooInputStream(); } } $b = new BarLoader(); $b->load(); $f = new FooLoader(); $f->load(); ?> --- InputStream.php <?php interface Stream { const SEEK_SET = SEEK_SET; const SEEK_CUR = SEEK_CUR; const SEEK_END = SEEK_END; public function seek($pos, $whence = Stream::SEEK_SET); } interface InputStream extends Stream { public function read(&$data); } ?> --- BarInputStream <?php require_once 'InputStream.php'; abstract class BarStream implements Stream { public function seek($pos, $whence = Stream::SEEK_SET) { echo __CLASS__, '->', __FUNCTION__, '()', "\n"; } } class BarInputStream extends BarStream implements InputStream { public function read(&$data) { echo __CLASS__, '->', __FUNCTION__, '()', "\n"; } } ?> --- FooInputStream <?php require_once 'InputStream.php'; abstract class FooStream implements Stream { public function seek($pos, $whence = Stream::SEEK_SET) { echo __CLASS__, '->', __FUNCTION__, '()', "\n"; } } class FooInputStream extends FooStream implements InputStream { public function read(&$data) { echo __CLASS__, '->', __FUNCTION__, '()', "\n"; } } ?> ---END I will add a short notice (if that serve): this will not happen if you don't call $bar->seek(1). ------------------------------------------------------------------------ [2006-08-02 10:16:52] [EMAIL PROTECTED] Please provide SHORT but COMPLETE reproduce script. I don't think you need a bunch of files to get such a simple error message. I'm pretty sure it's possible to reproduce it with just a couple of classes in 10 lines. # unzip stream-bugs.zip Archive: stream-bugs.zip creating: Stream/ inflating: Stream/BarInputStream.php inflating: Stream/BarLoader.php inflating: Stream/BarStream.php inflating: Stream/bug.php inflating: Stream/FooInputStream.php inflating: Stream/FooLoader.php inflating: Stream/FooStream.php inflating: Stream/InputStream.php inflating: Stream/Loader.php inflating: Stream/Stream.php I don't see any "bug.php" or anything else that could help first of all to understand what is the problem. ------------------------------------------------------------------------ [2006-08-02 06:05:54] baldurien at bbnwn dot eu If you read carefully, then you'll find a link : http://www.bbnwn.eu/works/stream-bugs.zip This an archive file containing all the sources (eg: the test case for the bug), which when you call the file "bug.php" will show you an example of bug. I can't provide it on the server, as a PHP file, as it is a php4 server (which does not support interface). If you want a txt file with all the code inlined, then no : the bug is DUE to the presence of require_once. The sole thing I can do is to prepend the name of each file before, meaning you will have the create each file on your own, while they are in the archive file. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
