How To Save A Programms State?

criu is probably the most up to-date project and probably your best shot but depends also on some specific Kernel options which your distribution probably hasn't set. Now I want to install some updates and actually restart the laptop (the "please reboot" message is just annoying). A ZODB beginner's tutorial is available here: http://www.h7.dion.ne.jp/~harm/ZODB-Tutorial.py Other info at: http://zope.org/Members/adytumsoluti...LoveZODB_PartI http://zope.org Hope information helps.

Then, if you accidentally go too far and miss the critical statement, instead of having to restart your program from the beginning, you can just go back to the checkpoint and The following example is not from my actual code, but what happens is the same.

Similarly, the actual contents of files that have been changed cannot be restored (at this time). But does that mean they have exactly identical memory models? delete checkpoint checkpoint-idDelete the previously-saved checkpoint identified by checkpoint-id. Returning to a previously saved checkpoint will restore the user state of the program being debugged, plus a significant subset of That said, dumping the raw memory requires privileges that only the operation system is supposed to have.

Each has a reason why it may not work. I started to write code to get around this. Linux Process Checkpointing Dijkstra path finding in C# is 15x slower than C++ version Why can't we remove the sqrt from rms? Criu I would encourage you to have your program output to a file "checkpoint" data.

But I'm stuck, because unpickling (so far as I understand it) creates a brand new instance that doesn't know it used to have references to itself in the globalstate lists. this content I'm using the pickle module to implement this. The incompatibilities sound to me as if you took a MacOS process and dumped it onto a Windows box; that's really quite amazing. –cat May 7 '16 at 15:33 add a See code changes below: (code contained in "saveload" module) import pickle import world import globalstate def savegame(path_to_name): world_data = {} for attr, value in world.__dict__.items(): # actual code is selective about Python Pickle

This can be especially useful if it takes a lot of time or steps to reach the point where you think the bug occurs. self.foo = 23 # this is an 'instance variable/name' .... Depending on your hypervisor you can also move the machine between different hosts. weblink pass Now just create an instance and add your attributes.

But now comes the save and restore game functions, which again are simplified from my real code: My understanding of pickle is that it will correctly handle shared references in the You could even have a go at setting one up yourself (look up Oracle Grid Engine). –Wojtek Rzepala Aug 2 '12 at 8:25 I never thought of this beeing Neutralize data How could I make something "immune" to nanotechnological disassembly?

Thus, if you're stepping thru a program and you think you're getting close to the point where things go wrong, you can save a checkpoint.

Is there a model structure on (strict?) Monoidal Categories? When I update the instance attributes in one place, the changes are reflected in the other place. Schneider 29 1 Why those? As I have limited resources only, I started this on my Ubuntu 12.04 (x86) laptop.

Also another idea is to use a class instead of a global. This data should be sufficient that your program will be able to resume from the state it was at when the checkpoint file was saved.
