#49781 [Opn->Fbk]: stream_get_meta_data seeks past http headers

ID: 49781 Updated by: sjoerd@php.net Reported By: marques at displague dot com -Status: Open +Status: Feedback Bug Type: Streams related Operating System: linux PHP Version: 5.2.11 New Comment: Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report.

The result is that if you want to use stream_filter_prepend or stream_filter_append (after examining the meta data) your first bucket will contain data after the meta data (HTTP headers) and some of the initial content. While trying to implement a chunked stream filter for PHP < 5.3.1 I experienced this. The first bucket begins just after the hex chunklen of the second chunk. Switching to an fgets() loop on the headers (and stopping at the first empty line) corrects this. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=49781&edit=1
