If I'm being pedantic about the option "--checkpoint-open-files", this
means that the subject case is not handled.
True statement?
In other words, often processes will create a file, write some stuff, and
close it. It would be nice if DMTCP had an option to bookkeep those files
and store them in the `ckpt*_files` folder along with contents of open
files at the checkpoint time.
This allows a more precise capture of the process state and supporting
files which may be required for migrating said process to other machines,
etc.
This seems doable, with just a simple array to handle previously opened
files, and an option to copy those files to ckpt_files on checkpoint, and
to restore them to previous location on restart (of course included
pathvirt functionality as well ;->).
Thoughts? Comments? Edge cases? Already supported and I missed it?
Thanks,
Kyle Harrigan
