copies: detect files as `touched/salvaged` if they only existed on one side The file cannot be merged if there was content to merge on the other side. So the previous record was wrong. In the general case, the file existed only on one side and got touched during the merge. So it should detected as touched. They are a special case where the merge manually prevent the file to be deleted. In this case the file is marked as `salvaged`. The result of this `salvaged` recording, copy-tracing-wise, is the same as recording it as `merged`. This is probably why they were recorded as `merged` in the first place.

47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	372 Subcase (A) is the simpler, nothing happend on parent-A side while

47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	376 - the file is not marked as touched by the merge.

47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	378 Subcase (B) is the counter part of "Special case [1]", the file was
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	379 modified on parent-B side, while parent-A side deleted it. However this
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	380 time, the conflict was solved by keeping the file (and its
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	381 modification). We consider the file as "salvaged".

47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	383 The result:
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	384 - the file is marked as "salvaged" by the merge.

47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	386 Subcase (C) is subtle variation of the case above. In this case, the
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	387 file in unchanged on the parent-B side and actively removed on the
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	388 parent-A side. So the merge machinery correctly decide it should be
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	389 removed. However, the file was explicitly restored to its parent-B
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	390 content before the merge was commited. The file is be marked
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	391 as salvaged too. From the merge result perspective, this is similar to
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	392 Subcase (B), however from the merge resolution perspective they differ
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	393 since in (C), there was some conflict not obvious solution to the
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	394 merge (That got reversed)

47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	396 Special case [3]:
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	397
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	398 The situation is:
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	399 - parent-A: file,
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	400 - parent-B: file (different filenode as parent-A),
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	401 - working-copy: file (same filenode as parent-B).
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	402
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	403 This case is in theory much simple, for this to happens, this mean the
47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	404 filenode in parent-A is purely replacing the one in parent-B (either a

47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	406 introduce no changes, and the file is not affected by the merge...

47ad23549b81 changing-files: add clean computation of changed file for merges Pierre-Yves David <pierre-yves.david@octobus.net> parents: 45667 diff changeset	412 (while the "merge" should have led to a "modification").
