[PHP-BUG] Bug #64803 [NEW]: async stream_socket_client return
From: rdlowrey at gmail dot com Operating system: Fedora 17 PHP version: 5.4.15 Package: Streams related Bug Type: Bug Bug description:async stream_socket_client return Description: Normally when creating a client socket connection asynchronously you have to wait until the socket stream can be selected as writable to determine whether or not the connection succeeded. However, when connecting to a nonexistent server on the loopback address there is no way to differentiate between a failed connection and a successful connection using the STREAM_CLIENT_ASYNC_CONNECT flag. The example code connects to a nonexistent server so it should always fail. PHP reports the connection as having succeeded and it's not until you actually attempt to read or write to the socket stream that you can get an accurate `feof()` return value.

[PHP-BUG] Bug #64921 [NEW]: Inconsistent stream_select() behavior for php://memory vs. php://temp
From: rdlowrey at gmail dot com
Operating system: Fedora 17
PHP version: 5.4.15
Package: Streams related
Bug Type: Bug
Bug description:Inconsistent stream_select() behavior for php://memory vs.
php://temp
Description:
Streams of type php://memory cannot be represented as selectable
descriptors
where stream_select() is concerned. Attempting to do so will (rightly)
trigger an
E_WARNING along the lines of "Warning: stream_select(): cannot represent a
stream
of type MEMORY as a select()able descriptor in ..."
I would expect streams of type php://temp to behave the same way. However,
this
is not the case. Instead, php://temp streams are immediately readable (but
do not
evaluate to TRUE for feof($stream). These streams should either (1) trigger
an
error similar to that of php://memory or (2) not be represented as readable
by
stream_select().
Test script:
---
$stream = fopen('php://memory', 'r+');
$r = array($stream);
$w = $e = NULL;
stream_select($r, $w, $e, 0); // E_WARNING (as expected)
$stream = fopen('php://temp', 'r');
$r = array($stream);
$w = $e = NULL;
if (stream_select($r, $w, $e, 0)) {
var_dump(feof($stream)); // this isn't readable and should never be
called but it results in bool(false)
}
Expected result:
The test script should trigger two warnings and neither stream should
report as
readable.
Actual result:
--
php://temp streams do not trigger an error when used with stream_select()
and are
immediately reported as readable.

UPDATE:
According to http://php.net/manual/en/wrappers.php.php php://temp DOES support
stream_select(). However, if this is the case, the behavior described here is
still incorrect because stream_select() reports that the descriptor is readable
even though it has no readable data and feof($stream) === FALSE.
