Hi,
We have two versions of client code, one using curl, and other one
using raw sockets via fsockopen(), and
we use the following code to set the i/o timeouts:
1) curl:
.
.
curl_setopt( $handle, CURLOPT_TIMEOUT, 1 );
From the manual
CURLOPT_TIMEOUT
The maximum number of seconds to allow cURL functions to execute.
Notice: "functions", I would take this as the entire process.
.
.
$resp = curl_exec($handle)
2) sockets:
stream_set_timeout( $sock, 1);
From the manual
Set timeout period on a stream
This would tell me that it is on the entire process, not just one
function call like fwrite() or fread().
Here we use frwrite() and fread() to send the request and read the
response respectively.
In (1), how is the timeout applied - is it:
a) timeout includes the entire curl_exec() call - the combined socket
write() ( to send the request ) and
the read() ( read the response ) calls.
or
True for both
b) timeout is independently applied to write() and read() end respectively.
False for both
Some of our tests seem to indicate it is (a).
In (2), I am assuming the stream timeout is applied at each i/o call
independently for fwrite() and fread() - I am pretty
much certain on this as this is how it would map to underlying C calls.....
It will be good to get a confirmation on our doubts.
Thanks,
Ravi
This is what I have experienced at least.
