[mapserver-users] disk space

[Fawcett, David]

Valerio, 
 
I think that most people just set up a cron job or a scheduled job on their server to delete all of the temporary images at some periodic interval.  (e.g. 24hrs, 12hrs, 1hr)  Your interfval would depend on the number of images that you are generating, disk space, etc.
 
In the code that you use to delete the files, you may want to look at the timestamps on the images and only delete images that are at least 1 minute old, so you don't accidentally delete an image before it can be used by the page that called it.

Thanks for the quick reply,

When you run this function? after each requests ? but if so, the client is able to read the image before you delete it ?

best regards,

Valerio

	Hi,

	 

	  Why don't you write method  for deleting png .mapserver will take care about creating an image.I have  C# code.

	The below code will delete all the files form OutputDIR.

	 

	I hope it helps you. Or At least you can get some idea about your task.

	 

	Thanks and Regards

	Venkat.

	 

	public void Deleteimages()

	{

	            try

	            {

	                foreach (string f in System.IO.Directory.GetFiles(OutputDir))

	                {

	                    System.IO.File.Delete(f);

	                }

	            }

	            catch (Exception exp)

	            { }

	}

Dear all,

I have a demo where I'm using mapserver cgi interface. I'm using the browse mode so each time mapserver receive a request, it creates a temporary png on the server filesystem. 

Do you know how and when i can delete those temporary image since they are used only one time ?  

An attacker could easily  fill all the server HD  locking all the system.

Thanks

Valerio
