From: jason at e7x dot com Operating system: Windows 2000/Linux PHP version: 4.3.9 PHP Bug Type: Filesystem function related Bug description: fread from userspace stream wrapper only reads 8192 bytes
Description: ------------ Attempting to fread() more than 8192 bytes from a userspace stream wrapper will only read and return the first 8192 bytes, putting an echo statement in stream_read() shows that it is only being called once. Reading <= 8192 bytes at a time works as expected, as does fgets($f, 15000) (reads 14999 bytes). This bug is only present in 4.3.9 and 4.3.10RC1, 4.3.8 works fine. Reproduce code: --------------- <?php // using example class from the manual: // http://uk.php.net/stream_wrapper_register $x = str_repeat('x', 15000); $f = fopen('var://x', 'r'); $len = strlen(fread($f, 15000)); fclose($f); echo "Read $len bytes"; ?> Expected result: ---------------- Read 15000 bytes Actual result: -------------- Read 8192 bytes -- Edit bug report at http://bugs.php.net/?id=30936&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30936&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30936&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30936&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30936&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30936&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30936&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30936&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30936&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30936&r=support Expected behavior: http://bugs.php.net/fix.php?id=30936&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30936&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30936&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30936&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30936&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30936&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30936&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30936&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30936&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30936&r=mysqlcfg
