From: cataphract Operating system: PHP version: trunk-SVN-2010-09-09 (SVN) Package: Streams related Bug Type: Bug Bug description:Out-of-date comment for file_get_contents/php_stream_copy_to_mem
Description: ------------ ext/standard/file.c#560 560 /* uses mmap if possible */ 561 if ((len = php_stream_copy_to_mem(stream, &contents, maxlen, 0)) > 0) { main/php_streams.h 431 /* read all data from stream and put into a buffer. Caller must free buffer when done. 432 * The copy will use mmap if available. */ 433 PHPAPI size_t _php_stream_copy_to_mem(php_stream *src, char **buf, size_t maxlen, 434 int persistent STREAMS_DC TSRMLS_DC); 435 #define php_stream_copy_to_mem(src, buf, maxlen, persistent) _php_stream_copy_to_mem((src), (buf), (maxlen), (persistent) STREAMS_CC TSRMLS_CC) main/php_streams.h 419 /* copy up to maxlen bytes from src to dest. If maxlen is PHP_STREAM_COPY_ALL, copy until eof(src). 420 * Uses mmap if the src is a plain file and at offset 0 */ 421 #define PHP_STREAM_COPY_ALL ((size_t)-1) In this last case, PHP_STREAM_COPY_ALL is also passed to php_stream_copy_to_stream_ex, which still uses mmap+mmap_unmap, so it's half correct (except for the part is works with any maxlen, not just PHP_STREAM_COPY_ALL). -- Edit bug report at http://bugs.php.net/bug.php?id=52802&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52802&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52802&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52802&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52802&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52802&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52802&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52802&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52802&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52802&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52802&r=support Expected behavior: http://bugs.php.net/fix.php?id=52802&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52802&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52802&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52802&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52802&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52802&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52802&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52802&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52802&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52802&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52802&r=mysqlcfg
