QuickPlot + MapGuide 2.3 (SVN)

Description

I've been trying to get the new quickplot feature working in MapGuide 2.3 SVN. I kept running into the dreaded:

The application resources required to generate the plot exceed the settings defined by the administrator

I checked to make sure that PHP was compiled with gd, etc and everything was fine on that end. I'm using the php viewer, and after a bunch of digging I found the culprit.

Line 119 of mapviewerphp/quickplotgeneratepicture.php

$tempImage = sys_get_temp_dir() . uniqid();

this makes $tempImage as "/tmp4ee7858739161" causing it to fail to create the file.

A better solution would be to use tempnam() in conjunction with sys_get_temp_dir.

Line 119 of mapviewerphp/quickplotgeneratepicture.php turns into:

$tempImage = tempnam(sys_get_temp_dir, "mgo");

Can you please add this fix to the SVN trunk.

Thanks!

Warren

you could also fix it by changing it to:

sorry it should read:

$tempImage = tempnam(sys_get_temp_dir(), "mgo");

Sorry it should read

$tempImage = tempnam(sys_get_temp_dir(), "mgo");

Nice work, can you create and attach a patch for this?

Also, it's best to post a quick message to mapguide-internals after filing a ticket

From my test, tempnam() doesn't work with PHP 5.3.8 + IIS7. That means we cannot fix the problem by tempnam(). We might simply add the path separator before uniqueid(): $tempImage = sys_get_temp_dir() . DIRECTORY_SEPARATOR . "mgo" . uniqid(); The code would work for both Windows and Linux.
