Bug description: stream_get_line() - allow $length to be optional
Description:
------------
I believe stream_get_line() should allow the $length parameter to be
optional by allowing a $length of -1 that would read the remaining buffer
up to either the $ending delimiter or EOF.
Currently if you pass a $length of 0, the $length defaults to
PHP_SOCK_CHUNK_SIZE (8192) in ext/standard/streamsfuncs.c. If you pass a
length of -1, a PHP Warning is generated.
Other 'similar' functions that allow length to be optional or -1 are
fgets, stream_get_contents, and file_get_contents.
Also, the manual page for stream_get_line() states that this function is
the same fgets() except for the handling of the delimiter - but another
difference, at least right now, is that the $length parameter is required
in stream_get_line(), but optional in fgets().
Reproduce code:
---------------
<?php
$fp = tmpfile();
fwrite($fp, str_repeat('a', 10000));
fseek($fp, 0);
echo strlen(stream_get_line($fp, 0));
fseek($fp, 0);
echo strlen(stream_get_line($fp, -1));
fclose($fp);
Expected result:
----------------
8192
10000
Actual result:
--------------
8192
Warning: stream_get_line(): The maximum allowed length must be greater
than or equal to zero
