narrow: also warn when not deleting untracked or ignored files Differential Revision: https://phab.mercurial-scm.org/D6265

setdiscovery: fix a few typos Differential Revision: https://phab.mercurial-scm.org/D6263

copies: delete debug message about "unmatched files new in both" Same reasoning as previous patch. Differential Revision: https://phab.mercurial-scm.org/D6251

copies: delete debug message about changes since common ancestor Same reasoning as previous patch. Differential Revision: https://phab.mercurial-scm.org/D6250

copies: delete debug message about search limit I'm about to rewrite mergecopies() and this message will no longer be emitted then. Let's remove the message now to remove a distraction from that patch. Differential Revision: https://phab.mercurial-scm.org/D6249

copies: move early return for "no copies" case a little earlier We can return before the block that prints debug messages. That block will not be run anyway when there are no copies. Differential Revision: https://phab.mercurial-scm.org/D6248

copies: fix up "fullcopy" with missing entries from "diverge" Similar to the previous patch, but this doesn't even affect tests. It does affect tests if you change them to turn on debug logging. I'm fixing it here so reviewers of the later rewrite patch can hard-code debug logging to be on and more easily compare test results. Differential Revision: https://phab.mercurial-scm.org/D6247

copies: fix up "fullcopy" with missing entries from "copy" This is just a workaround similar to the previous one. It will make it easier to follow later patches. Differential Revision: https://phab.mercurial-scm.org/D6246

merge: remove workaround for issue5020 As I explained in the previous commit, I think the filtering added there is a better fix for the issue, so the workaround from 41f6af50c0d8 (merge: fix crash on criss cross merge with dir move and delete (issue5020), 2017-01-31) should no longer be needed.

copies: don't include copies that are not in source in directory move I've been working on a rewrite of mergecopies(). I compared the output of the rewritten version with the current version. I noticed that between FIREFOX_NIGHTLY_59_END and FIREFOX_BETA_60_BASE in the mozilla-unified repo, there were many copies that the current version detected that the rewritten version did not. One example was js/src/gc/Iteration.h -> js/src/gc/PublicIterators.h. Then I realized that js/src/gc/Iteration.h doesn't even exist in FIREFOX_NIGHTLY_59_END. This patch adds a filtering step for the "fullcopy" dict. It turns out that that change also affects the test for issue5020 in test-merge-criss-cross.t. The 'dm' action no longer happens there. At first I thought that the test case change meant that this patch was broken, but I think it's actually correct tha the 'dm' action should not happen there. The result of the bid merge is still the same. I suspect this filtering is a better solution for the issue than 41f6af50c0d8 (merge: fix crash on criss cross merge with dir move and delete (issue5020), 2017-01-31). I also suspect that it was broken just a few months earlier by a005c33d0bd7 (mergecopies: add logic to process incomplete data, 2016-10-04). Note that bid merge had been enabled for a few years at that point, since 19903277f035 (merge: use bid merge by default (BC), 2014-10-01). This patch is still just a workaround. It will be cleaned up soon (with the rewrite of mergecopies()). But doing this in a separate patch makes later patches easier to understand and gives a place to explain why this is changing.
