This one feels like pylint/mypy should notice? Maybe adding some type hints would help? |
There is a chance bigger than 0 that it might say "yes" now. I updated the code on my testbench, restarted qubesd and qubes-qmemman, started some domains, shutdown others, started various domains, updated all templates. No errors so far. |

This comment belongs to MEM_OVERHEAD_FACTOR - if you move one, move the other too.

I moved the top part of the commend until see link because the rest we divide appears to be related to the code after.

If you don't use key, the maybe iterate over values()?

Later commit fixes it, but this one mixes prev_mem_actual iteration) with self.domdict - dom is the former here, not the latter. (and similar few lines above and below). Please adjust this commit to not introduce a bug temporarily.

Please don't, this doesn't save much (just one empty parameter), but makes it harder to see if it's a read or write (and easier to make a mistake).
OTOH the get_xs_path helper is useful change.

The idea of this function was to be concise, the new name kinda fails at that... If you don't like a function MB, maybe define it as a constant to multiply by instead?

The same comment as in the other place.
- Enable pylint; - Rename keyword 'id' or variable 'i' to 'domid', which is always xid but better to use a VMM agnostic name; - Move constants to module scope; - Pylint trips on dictionary iteration of .keys() with 'consider-using-dict-items' and 'unnecessary-dict-index'. Fixing that helped find some useless assignments which were already objects of the dictionary; - Assign current domain dictionary domid looping to an object for easier reading and modification; and - Separate 'do_balance()' to avoid 'too-many-nested-blocks'.
