Description Daniel Thaler 2011-07-11 14:47:41 UTC

Version:           0.6.2 (using KDE 4.6.3) 
OS:                Linux

I tried to load a 2.5Gb data file with okteta.
This failed with the message "There is not enough working memory to load this file", which was clearly wrong (the machine has 16GB).

From a brief look at the okteta code, it appears that a QByteArray is allocated for the file data in bytearrayrawfileloadthread.cpp and resized to the file size.
Unfortunately this cannot work for large files, because the parameter to QByteArray::resize() is an int.

Reproducible: Didn't try

Steps to Reproduce:
Try to load any file with a size greater than 2^31 bytes


Expected Results:  
The file should be loaded

Thanks for the report. Issue is known, the lack of proper support for very large files is pretty high on the TODO list, but not so straightforward solvable, so sadly might take some more time until I/someone finds the time for it (should not be done by loading/copying them completely into the working memory). Will mark this report as duplicate of the general bug for this issue.

Will fix the error message though, you are right in that it is wrong in the reason it gives.
