Possible wrong Result of "Calculate Cumulative File Size"

[NewsArchive]

Hi Friedrich,

it seems that the following script holds a wrong value in %SEARCHSIZE%
if the cumulative size exceeds 2GB.

Set Variable %SEARCHRESULT% to FUNCTION:Handle File Listing(Free
File List)
Set Variable %SEARCHRESULT% to FUNCTION:Handle File Listing(Load
File List, 1) of "%DATENTOUPDATEDIR%\*.BDB"
Set Variable %SEARCHSIZE% to FUNCTION:Handle File
Listing(Calculate Cumulative File Size)
Set Variable %SEARCHRESULT% to FUNCTION:Handle File Listing(Free
File List)

Could you check this please?

Thanks in advance.

Yes, that's possible. 2GB is the maximum here. We'll add this to the
documentation, thank you.

No, the function can handle 4GB, but the variable that receives the value
can only handle 2GB. We'll check if we can change this behavior.

Hi Friedrich,

this means, your(?) function uses an unsigned int and the script
variable is a signed int.

Is it possible to calculate with kBytes instead of bytes? So the limit
would be 2/4TB.

I ask this because 4GB is insufficient too in my case. I have customers
with more than 10GB...

Yes, that's correct.

The runtime can't handle values >4GB. Quite a few used Windows APIs do not
support Quad (U64) unsigned integer numbers.

Yes, this is surely true for a single file.

But what I thinked about is already possible within SB script, as long
as a single file is not larger than 2GB, but it's to slow:

- Get File List
- %ACCUMULATED_SIZE_IN_KB% = 0
- For each entry in the file list do
- - Get File Size and store in %FILESIZE%
- - %FILESIZE% = %FILESIZE% / 1024
- - %ACCUMULATED_SIZE_IN_KB% = %ACCUMULATED_SIZE_IN_KB% + %FILESIZE%

Should I really do that in SB script? What, if my file list (718 files)
is larger than 10kb?

Hi Markus,

I think what should work is a new "Calculate Cumulative File Size (KB)"
option that calculates the cumulative file size (in KB). I have added it to
the whishlist.

Thanks.

Update: The Get File Size functionality in SetupBuilder supports quad (U64)
unsigned integer numbers now.

Works in your actual build.
