[PHP] problem compiling 5.3 with postgresql
I am having problems compiling 5.3.? with postgresql support. './configure' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-pdo-pgsql=/usr/local/postgresql-9.0.3' '--with-pgsql=/usr/local/postgresql-9.0.3' This configure works with 5.2.?, but 5.3.? gets this ext/standard/.libs/dns.o: In function `php_parserr': /usr/local/php-5.3.5/ext/standard/dns.c:418: undefined reference to `__dn_expand' and more lines like the last one. How can I fix this? I am using Ubuntu 10.10. JIm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] script failing at same line
Ben, My solution was to add a table to my database, and add an insert job id into the table after the line that is causing the problem. When I submit the script I use setTimeout to run an AJAX query of the table 5 seconds later. If the line has failed the job id will not be in the table and I alert the user. It works - and some day I hope to fix the software problem and make this unnecessary.

[PHP] script failing at same line
Hi, I have a script that intermittently fails at the same line. I am trying to write some code that will throw an exception after 5 seconds if the command on that line fails and the script freezes. Any ideas? Jim White -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] script failing at same line
$map = ms_newMapObj($mapfile); The command creates a new mapscript object. Jay Blanchard wrote: [snip] I have a script that intermittently fails at the same line.

But those really won't help you :) We need to see the code at that line and be told what is being done in order to make a reasonable guess. My bet is that the data being fed to the script has a character that is not expected or something. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] script failing at same line
Hi, Thanks I'll look at libevent. I have also been thinking about using an XHR approach, but wonder how passing PHP references works with javascript.

Re: RE: [PHP] flushing AJAX scripts
My page submits the AJAX request to complete a report that takes some time, and upon completion stores results in a database. A second AJAX request polls every 5 seconds and queries the database if the report is ready. This hopefully will get around any timeout problems I am having with a long running request, and seems to be working. It looks like I can accept the default behavior for now. I don't depend on getting a response from the original request, but is there a point where the AJAX response script will be stopped either by Apache or PHP before it can insert into the database? Jim Andrea Giammarchi wrote: Some browser would like to receive at list N characters (bytes) even if you force the flush, before the browser will show those characters. In any case, the Ajax request will not be completed until its readyState will be 4, which means the page execution on the server has finished (released, php has gone, flush or not flush) For a task like this one you have few options: 1 - launch new thread if your host is able to do it 2 - use a Comet like response (for php I wrote Phico some while ago) In any case, I hope this stressful operation cannot be performed from thousand of users or you can say bye bye to the service. Alternatives: 1 - optimize your database 2 - delegate the job once a time rather than every click (cronjob) 3 - if the bottleneck is PHP, create an extension in C to perform the same task Hope this help. Regards P.S. Internet Explorer a part, you can read the responseText on readystate 3 which will be called different time (most likely for each flush). If IE is not your target, you could consider this opportunity to read the sent stream so far.

Re: RE: [PHP] flushing AJAX scripts
Well, the point was that I had tried the first way, submitting one AJAX request and waiting for it to finish and it was timing out, probably on my firewall which it shouldn't have - but it did. The reports can take 10 seconds or 10 minutes to create. Doing it this way I can still load the report even if the original request shuts down after 3-4 minutes.

I mean, when the first request inserts data in the database that's it, you'll manage the end of the request. $A --- do stuff; do stuff; do stuff; report ready; $B --- report ready? $B --- report ready? $B --- report ready? $B --- report ready? report ready; --- notification to A $B --- report ready; the report ready, if it is when $A request has been finished, will be in $A, the polling via $B is absolutely useless, imo. There is no timeout from Ajax, it simply keep waiting, but obviously if your PHP has max_execution_time 30 seconds and the script execution takes more than 30 seconds there's no polling that could save you. The same if the user closes the browser, connection lost, bye bye response. To have a notice, you need Comet, try out Phico but still, a page that requires that much is not suitable for the web. Report creation should be a cronjob in a separed thread if it is that stressful.

[PHP] flushing AJAX scripts

I have tried several thing such as ob_start(); echo json_encode(array(time=$now, message=Report has started running!)); ob_end_flush(); However, the script does not respond and (I suppose close the connection) until the report is complete.
