Since I'm not yet familiar with Darcs' internal workings, can someone
help me understand why calculating a minimal context is so expensive?
Is it because Darcs doesn't have quick access to patch summaries and
must load every patch, in its entirety, from disk to perform a
If that's the reason, is it possible to store patch summaries (like
"hunk ./src/Darcs/Repository/Merge.hs 83 -1 +1") in the inventory
files? To my naive understanding, it seems that many commutations
could be calculated with just those summaries.
Thanks for any insight.
