[pdal] Correct destination file guarantee?

[Peder Axensten]

Hi!

If pdal is interrupted while saving to the destination file, it might result in a corrupt file. This is not unreasonable, but could be avoided.

We use a make script to process large amounts of files and sometimes we have to interrupt processing for different reasons. We then risk to have corrupt files that make will consider final when rerunning the script, so the files are left in a corrupt state.

Would it be a good idea to make pdal by default save the contents to a temporary file and then move the temporary file to the destination file? This way either a correct file is produced or nothing. I'm implementing this in the make script – it is somewhat cumbersome but will work ok, I guess.

Isn’t it a very attractive and useful guarantee: if the destination file is produced, then it is correct?

Best regards,
