largefiles: rewrite merge code using dictionary with entry per file
In overridecalculateupdates(), we currently only deal with conflicts
that result in a 'g' action for either the largefile or a standin. We
will soon want to deal cases with 'cd' and 'dc' actions here. It will
be easier to reason about such cases if we rewrite it using a dict
from filename to action.
A side-effect of this change is that the output can only have one
action per file (which should be a good change). Before this change,
when one of the tests in test-
issue3084 received this input (the 'a'
in the input was a result of 'cd' conflict resolved in favor of the
modified file):
'g': [('.hglf/f', ('',), 'remote created')],
'a': [('f', None, 'prompt keep')],
and the user chose to keep the local largefile, it produced this
output:
'g': [('.hglf/f', ('',), 'remote created')],
'r': [('f', None, 'replaced by standin')],
'a': [('f', None, 'prompt keep')],
Although 'a' actions are processed after 'r' actions by
recordupdates(), it still worked because 'a' actions have no effect on
merges (only on updates). After this change, the output is:
'g': [('.hglf/f', ('',), 'remote created')],
'r': [('f', None, 'replaced by standin')],
Similarly, there are several tests in test-largefiles-update that get
inputs like:
'a': [('.hglf/large2', None, 'prompt keep')],
'g': [('large2', ('',), 'remote created')],
and when the user chooses to keep the local largefile, they produce
this output:
'a': [('.hglf/large2', None, 'prompt keep'),
('.hglf/large2', None, 'keep standin')],
'lfmr': [('large2', None, 'forget non-standin largefile')],
In this case, it was not a merge but an update, so the 'a' action does
have an effect. However, since dirstate.add() is idempotent, it still
has no obserable effect.
After this change, the output is:
'a': [('.hglf/large2', None, 'keep standin')],
'lfmr': [('large2', None, 'forget non-standin largefile')],
