Hi All,
I use register_shutdo wn_function to register a function that then gets run
when the script finishes executing. It worked great before, but sometime
last week on my development server all my sites started going very slowly.
It is still running fine on the production server (thankfully).
Nothing was changed. In fact, I was out of town that week, and the dev
server was powered off.
I did a little investigation, trying to locate the source of the slowdown,
and eventually I narrowed it down to the line:
register_shutdo wn_function('si teShutdown');
Commenting out that line made things run perfectly again (generates within
20-80 ms, depending on the page size). Uncomment it, and the page takes 3-4
seconds to generate. It does not generate piecemeal, either; it is blank
for several seconds, then in blink, the entire page arrives.
Has anyone got any ideas? What could cause this, and how could it suddenly
start happening, without me making any changes?
Sincerely,
-Josh

based on the experiences i've had with register_shutdo wn_function, it
seems that, while it makes the function you specify the last function
executed, it doesn't make it execute after the connection has been
closed. the work around to this that i used involved sending a whole
new http request, with fsocketopen and fputs, but never reading the
data. the script i would send the request to would check to see if
the originating ip address of the request was the same as the server's
ip address, among other things. not a particurarly pretty solution,
but whatever, heh.

I use this function regularly without any problems - suggest U look at what
you are doing within function siteShutdown()

I came across this function as i got a problem with very long-running
scripts which use transactions...
in the php manual i do not see clearly stated if the function defined
will be executed if a timeout is reached.
It states:
"Registers the function named by function to be executed when script
processing is complete."

I have a basic custom collection that throws a new

This is used as part of a calling function. It all works
correctly, the problem (discovered using a memory
profiler) is that the base exception being thrown in the
collection is not being disposed of.
I understand about the GC etc etc. It appears that
something is hanging on to a reference to System.Exception

Hi,
I have a script which after a time shows the following error in IE:
"A script on this page is causing Internet Explorer to run slowly. If
it continues to run, your computer may become unresponsive".
The page is quite complex and uses ajax to post updates to the server,
updating parts of the page based on the response. It uses YUI (event
and dom mainly). There are no infinite loops or similar constructs.

Does anything about this script look expensive, in terms of resources or
execution time? This script dies after processing about 20 or 25
numbers, yet it leaves no errors in the error logs. This is on a server
that handles a fairly demanding site. The defaults, in php.ini, have all
been cranked fairly high: scripts get 180 seconds to run, and they can
have as much as 256 megs of RAM.
The input for this script is coming from a textarea in...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
