#20703 [NEW]: session object's array is restored corruptly
From: [EMAIL PROTECTED]
Operating system: debian woody latest
PHP version: 4.2.2
PHP Bug Type: Class/Object related
Bug description: session object's array is restored corruptly
I'am not sure, if this is a in bug php, could be in my code, but I have
looked my code over and over and could not find anything...
So I describe my problem:
I have a session object, and it has an array variable.
In the code I do some array_shift, and array_push on one of the elements
of this array, wich is also an array. And I do something like this:
"get" return by reference from the session objects array:
$keyArray=&$object->get("key");
then I do array_shift, and array_push to maintain a FIFO like thing to
store the previous pagenames.
Now the problem:
normally this works in a number of pages, but in case of one page it acts
strangely: for some reason an extra element into the array appears like
this:
normally the array values should change when going from page5 to page6
from (now I am on page5):
page1
page2
page3
page4
page5
into (here there is a request for a new page: page6):
page2
page3
page4
page5
page6
but instead !!! it changes to:
page1
page5
page1
page6
page1
I tried to track down where this happens, and I found out, that is
happening between the __sleep and __wakeup methods, which would mean, that
serialize, and unserialize does not work correctly.
Another wery strange thing is that this work perfecly on the local
development server, which runs the same version of php...
so that's it... I am going mad now! bye..

#34851 [NEW]: SO_RECVTIMEO sec stands for usec!!!! and usec has no effect!
From: khayll at motoros dot hu
Operating system: win 2k3 server
PHP version: 4.4.0
PHP Bug Type: Sockets related
Bug description: SO_RECVTIMEO sec stands for usec and usec has no effect!
Description:
I tried to set a receive timeout for a socket, but found out that sec is
used as usec, and usec is in fact ignored!
Reproduce code:
---
using a modbus device with "address" address, sorry i cannot make it
available on the net
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, array("sec"=>0,
"usec"=>500));
socket_connect($socket, "address", "502");
socket_write($this->socket, $data, strlen($data));
socket_read($this->socket, 512, PHP_BINARY_READ);
Expected result:
expected to read some data or give a timeout error.
Actual result:
--
code hangs, so i figured out, that usec has no effect, then i tried 1 sec
as timeout, code began to work, but kept reporting timeout, so i figured
out if i try a value like 50 as sec it works. Seems like sec is used
as usec, and usec has no effect.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with ,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

Actual: Script gives timeout error but it does not wait for 5 seconds
for the answer, as set in SO_RCVTIMEO.
Expeted: to wait max. 5 second for remote host to answer, but script
executes much faster. I tried to increase second to 50 and then it
works ok.

Please read carefully what I wrote...
If I use 0 sec and 500 usec, the script HANGS when there's no response
(which means usec has NO EFFECT)! (Sorry I cannot reproduce remote
machine not sending a response, but accepting connections) and with a
setting of 1 sec 0 usec which is pretty much for a response I get a
timeout error.
here execute this script and it will show you the script execution time
is less than 1 sec at all giving a timeout:

Well, that's because USEC are *microseconds*, not milliseconds.
Try to use sec=0 usec=500 instead.
