#30157 [Asn]: ftell() function don't use stream_tell()

ID: 30157 Updated by: wez@php.net Reported By: tendencies at free dot fr Status: Assigned Bug Type: Filesystem function related Operating System: Windows and Linux PHP Version: 5CVS-2004-09-19 (dev) Assigned To: pollita New Comment: This tell patch (http://tony2001.phpclub.net/dev/tmp/userstreamop_tell.diff) is "wrong"; the position should be set implicitly when the stream is opened, and be updated by the streams layer when it knows that it is changed (as happens when you seek). If you need to determine the current position, you simply need to seek with a zero offset from the current position. Why did you need to add tell() function to the streams internals?

What do you think? ------------------------------------------------------------------------ [2005-04-05 23:30:52] tony2001@php.net Seems that Wez doesn't have enough time to work on it anymore. Sara, plz, take a look at this patch: http://tony2001.phpclub.net/dev/tmp/userstreamop_tell.diff The only problem I can see there is that all custom stream wrapper will have to add appropriate entries too. ------------------------------------------------------------------------ [2004-09-19 21:01:19] tendencies at free dot fr Description: ------------ For a test, I use wrapper_register() to register a new wrapper. For information, I use PHP5 CVS and apache. I want to create a wrapper and use ftell() to return an integer different from the length of the string (normal comportement). I implement the method stream_tell() and call ftell(), but surprise, this function don't use the method stream_tell(). Reproduce code: --------------- <?php class fileWrapper { var $fp; function stream_open($path, $mode, $options, &$opened_path){ $url = parse_url($path); $this->fp = fopen($url["host"], $mode); return true; } function stream_write($data){ return fwrite($this->fp, $data); } function stream_tell(){ echo "debug message"; return ftell($this->fp); } function stream_close(){ return fclose($this->fp); } } stream_wrapper_register("test", "fileWrapper"); $fp = fopen("test://file.txt", "w+"); fwrite($fp, "test"); echo "I test the echo debug in stream_tell() method:"; echo ftell($fp)."\n"; fclose($fp); ?> Expected result: ---------------- Use the code above, I write a "debug message" in the method stream_tell() but no message is writted in my screen, just this : I test the echo debug in stream_tell() method:0 I think that it's a bug but if not, all my apologies. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=30157&edit=1
