ID: 35849 Updated by: [EMAIL PROTECTED] Reported By: sqchen at citiz dot net -Status: Feedback +Status: Open Bug Type: Unknown/Other Function Operating System: redhat 7.3 PHP Version: 5.1.1 New Comment:
I can see two bugs in this report: * mmap()'ed fds aren't seeked() to update the position * the length is a size_t, where it should be a ssize_t, because PHP_STREAM_COPY_ALL is defined to -1 my patch: http://mega.ist.utl.pt/~ncpl/php_stream_mmap.txt it makes all negative values to read all the file (to be consistent with non-mmap'ed fds). I can also see some long/size_t/ssize_t mixes, which can be problematic in some platforms.
