Re: [PHP-WIN] Concurrency issue on session file on harddisk
I should preface this by saying it has been a while since I have used php extensively, but my suggestion would be to try putting in a delay at the beginning of your PHPfile, before the session_start() command (or whichever method you choose to begin your session). As far as I can recall, the session needs to be initialized before any output is sent to the browser, but this does not mean you cannot execute a php code delay before you start the session. This may give you enough time for the other PHP request to complete, freeing up the required file. A potentially more robust, but equally untested option, would be to check the file itself before initializing the session. The session_id will be available in the super variables or via session_id(). Since the file names for a given session are based predictably on this id, you could potentially try to do a read access on the file. If this fails, poll and try again or timeout and fail gracefully. I am not very familiar with how the permissions on this would play out though. Those are two suggestions I could think of, hope that helps, -Michael Southworth On Feb 13, 2008 8:15 AM, Stephan Weiher <[EMAIL PROTECTED]> wrote: > Thanks for the answer but this won't help us anyway.

Re: [PHP-WIN] Concurrency issue on session file on harddisk
Thanks for the answer but this won't help us anyway. We cannot enable javascript on any computer in the company's network to make this issue going away. I'll need a way to delay the requests for one of the two frames (defined in the frameset) for a tiny amount of time to prevent two php.exe instances from accessing the session file at the same time. But I don't know how to do so. Javascript is no option for us and as far as I know HTML has no such mechanism. So I need another way. Perhaps sth. that delays the call of php.exe - but I/O must work on this way :) Greetings Stephan Weiher ""Jacob Kruger"" <[EMAIL PROTECTED]> schrieb im Newsbeitrag news:[EMAIL PROTECTED] >A 'corny' workaround might be to get something like the nav frame in fact >to > then load the main frame using something like JavaScript - just a > thought - > since it would in fact first have rendered before the main frame was > loaded. > > You could then also put something like a 'waiting...' notice/string in the > main frame in case one or two people's machines in fact rendered/loaded > the > two frames in the wrong order. > > Stay well > > Jacob Kruger > Blind Biker > Skype: BlindZA > '...Fate had broken his body, but not his spirit...' > > - Original Message - > From: "Stephan Weiher" < > [EMAIL PROTECTED]> > To: < > php-windows@lists.php.net> > Sent: Tuesday, February 12, 2008 12:06 PM > Subject: [PHP-WIN] Concurrency issue on session file on harddisk -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
