In this case, the file hash from "f-2" is lower, so it will be `p1` of the resulting filenode its copy tracing information will win (and trace back to "h"):

In this case, the file hash from "f-2" is lower, so it will be `p1` of the resulting filenode its copy tracing information will win (and trace back to "h"):

Details on this hash ordering pick:

  $ hg manifest --debug 'desc("g-1")' | egrep 'd$'
  7bded9d9da1f7bf9bf7cbfb24fe1e6ccf68ec440 644   d (no-changeset !)

  $ hg status --copies --rev 'desc("i-0")' --rev 'desc("g-1")' d
  A d
    a (no-changeset no-compatibility !)

  $ hg manifest --debug 'desc("f-2")' | egrep 'd$'
