For some reason php_stream_flush() fails to actually write the data while still calling seek and resetting the stream position. Suggested solution: - Find out why php_stream_flush() fails and fix it (I don't know enough about it) - Mark (some? all?) stdio streams as PHP_STREAM_FLAG_NO_SEEK in sapi/cli/php_cli.c (see patch) - Mark stdio streams as PHP_STREAM_FLAG_NO_SEEK in ext/standard/php_fopen_wrapper.c Reproduce code: --------------- php -r 'echo "hello1\n"; posix_isatty(STDOUT); echo "hello2\n";' >out; cat out Expected result: ---------------- hello1 hello2 Actual result: -------------- hello2 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=49819&edit=1
