Activ4d used memory in Active4D 5

[Oliver Brodwolf]

Hello Aparajita

I'm looking to the memory which is used from 4D. (I had a lot of  
problems in 4D 2004, that to much memory was eating each request).
Is there a way to find out, how much memory Active4D uses?
Size of current request Collections
Size of global Collections
Size of total Active4D Memory used


And could it be, that Active4D still leaves collection in memory,  
which are not used

And if I do this:

$cTest:=new collection

$cTest:=new collection
....

Is the first collection deleted from memory? The same in global  
collections?

Regards, Oliver

Hello

I hope it's ok, to write each time, something does work different in  
Active 4.5 to Active 5.

<%
writebr(STRING("x"="x";"1;;0"))
//A4D 4.5 -> "1"
//A4D 5 -> "true"

writebr(STRING(num("x"="x");"1;;0"))
//A4D 4.5 -> "1"
//A4D 5 -> "1"

%>

Please report it on the issue tracker.

Not directly. If you create a session with the same items, you can use  
GET SESSION STATS to see the memory usage for each data type. Then you  
could write a library method that would calculate the usage for any  
collection.


> Size of total Active4D Memory used

No way I can easily calculate this.

It's possible, I'm still in beta.

With local collections, yes. With global collections, no, you are  
responsible for deleting them. That's why the documentation for 'new  
global collection' says:

"Warning: Be sure to store the handle in a place where you can  
retrieve it later, such
as in the globals collection."

It is also possible that 4D is leaking.

Hello Aparajita

There is another crash in a http-Request.
Can you see, where I should search?





It would be great, if we could see, in the Active4D.log the last line  
and include-file Path.
So if log_debug_level is switched to debug_extendet, you write each  
file-Path and each line or line number in the log file.
I think in the next time, there will be a lot of crashes, and with  
this, I and others could help much easier to find out, where the  
problem is.

Regards, Oliver
