copies: calculate mergecopies() based on pathcopies()

When copies are stored in changesets, we need a changeset-centric
version of mergecopies() just like we have a changeset-centric version
of pathcopies(). I think the natural way of thinking about
mergecopies() is in terms of pathcopies() from the base to each of the
commits. So if we can rewrite mergecopies() based on two such
pathcopies() calls, we'll get the changeset-centric version for
free. That's what this patch does.

A nice bonus is that it ends up being a lot simpler. mergecopies() has
accumulated a lot of technical debt over time. One good example is the
code for dealing with grafts (the "partial/incomplete/dirty"
stuff). Since pathcopies() already deals with backwards renames and
ping-pong renames, we get that for free.

I've run tests with hard-coded debug logging for "fullcopy" and while
I haven't looked at every difference it produces, all the ones I have
looked at seemed reasonable to me. I'm a little surprised that no more
tests fail when run with '--extra-config-opt
experimental.copies.read-from=compatibility' compared to before this
patch. This patch also fixes the broken cases in test-annotate.t and
test-fastannotate.t. It also enables the part of test-copies.t that
was previously disabled exactly because mergecopies() needed to get a
changeset-centric version.

One drawback of the rewritten code is that we may now make
remotefilelog prefetch more files. We used to prefetch files that were
unique to either side of the merge compared to the other. We now
prefetch files that are unique to either side of the merge compared to
the base. This means that if you added the same file to each side, we
would not prefetch it before, but we would now. Such cases are
probably quite rare, but one likely scenario where they happen is when
moving from a commit to its successor (or the other way around). The
user will probably already have the files in the cache in such cases,
so it's probably not a big deal.

Some timings for calculating mergecopies between two revisions
(revisions shown on each line, all using the common ancestor as base):

In the hg repo:
4.8 4.9: 0.21s -> 0.21s
4.0 4.8: 0.35s -> 0.63s

In and old copy of the mozilla-unified repo:
FIREFOX_BETA_60_BASE^ FIREFOX_BETA_60_BASE: 0.82s -> 0.82s
FIREFOX_NIGHTLY_59_END FIREFOX_BETA_60_BASE: 2.5s -> 2.6s
FIREFOX_BETA_59_END FIREFOX_BETA_60_BASE: 3.9s -> 4.1s
FIREFOX_AURORA_50_BASE FIREFOX_BETA_60_BASE: 31s -> 33s

So it's measurably slower in most cases. The most significant
difference is in the hg repo between revisions 4.0 and 4.8. In that
case it seems to come from the fact that pathcopies() uses
fctx.isintroducedafter() (in _tracefile), while the old mergecopies()
used fctx.linkrev() (in _checkcopies()). That results in a single call
to filectx._adjustlinkrev(), which is responsible for the entire
difference in time (in my repo). So we pay a performance penalty but
we get more correct code (see change in
test-mv-cp-st-diff.t). Deleting the "== f.filenode()" in _tracefile()
recovers the lost performance in the hg repo.

There were are few other optimizations in _checkcopies() that I could
not measure any impact from. One was from the "seen" set. Another was
from a "continue" when the file was not in the destination manifest
(corresponding to "am" in _tracefile).

Also note that merge copies are not calculated when updating with a
clean working copy, which is probably the most common case. I
therefore think the much simpler code is worth the slowdown.

     """
     Finds moves and copies between context c1 and c2 that are relevant for
     merging. 'base' will be used as the merge base.
 
     Copytracing is used in commands like rebase, merge, unshelve, etc to merge
     files that were moved/ copied in one merge parent and modified in another.
     For example:
 
     o          ---> 4 another commit
     |
     |   o      ---> 3 commit that modifies a.txt
     |  /
     o /        ---> 2 commit that moves a.txt to b.txt
     |/
     o          ---> 1 merge base
 
     If we try to rebase revision 3 on revision 4, since there is no a.txt in
     revision 4, and if user have copytrace disabled, we prints the following
     message:
 
     ```other changed <file> which local deleted```
 
     Returns five dicts: "copy", "movewithdir", "diverge", "renamedelete" and
     "dirmove".
 
     "copy" is a mapping from destination name -> source name,
     where source is in c1 and destination is in c2 or vice-versa.
 
     "movewithdir" is a mapping from source name -> destination name,
     where the file at source present in one context but not the other
     needs to be moved to destination by the merge process, because the
     other context moved the directory it is in.
 
     "diverge" is a mapping of source name -> list of destination names
     for divergent renames.
 
     "renamedelete" is a mapping of source name -> list of destination
     names for files deleted in c1 that were renamed in c2 or vice-versa.
 
     "dirmove" is a mapping of detected source dir -> destination dir renames.
     This is needed for handling changes to new files previously grafted into
     renamed directories.
 
     This function calls different copytracing algorithms based on config.

     Assumes that moves or renames are of following two types:
 
     1) Inside a directory only (same directory name but different filenames)
     2) Move from one directory to another
                     (same filenames but different directory names)
 
     Works only when there are no merge commits in the "source branch".
     Source branch is commits from base up to c2 not including base.
 
     If merge is involved it fallbacks to _fullcopytracing().
 
     Can be used by setting the following config:
 
         [experimental]
         copytrace = heuristics
 
     In some cases the copy/move candidates found by heuristics can be very large
     in number and that will make the algorithm slow. The number of possible
     candidates to check can be limited by using the config
     `experimental.copytrace.movecandidateslimit` which defaults to 100.

 Issue3841: check annotation of the file of which filelog includes
 merging between the revision and its ancestor
 
 to reproduce the situation with recent Mercurial, this script uses (1)
 "hg debugsetparents" to merge without ancestor check by "hg merge",
 and (2) the extension to allow filelog merging between the revision
 and its ancestor by overriding "repo._filecommit".

 first graft something so there's an additional entry:

 Check for issue4405
 -------------------
 
 Setup the repo with a file that gets moved in a second commit.
   $ hg init repo
   $ cd repo
   $ touch a0
   $ hg add a0
   $ hg commit -m a0
   $ hg mv a0 a1
   $ hg commit -m a1
   $ hg up -q 0
   $ hg log -G --template '{rev} {desc}'
   o  1 a1
   |
   @  0 a0
   
 
 Now we branch the repro, but re-use the file contents, so we have a divergence
 in the file revlog topology and the changelog topology.
   $ hg revert --rev 1 --all
   removing a0
   adding a1
   $ hg ci -qm 'a1-amend'
   $ hg log -G --template '{rev} {desc}'
   @  2 a1-amend
   |
   | o  1 a1
   |/
   o  0 a0
   
 
 The way mercurial does amends is by folding the working copy and old commit
 together into another commit (rev 3). During this process, _findlimit is called
 to  check how far back to look for the transitive closure of file copy
 information, but due to the divergence of the filelog and changelog graph
 topologies, before _findlimit was fixed, it returned a rev which was not far
 enough back in this case.
   $ hg mv a1 a2
   $ hg status --copies --rev 0
   A a2
     a0
   R a0
   $ hg ci --amend -q
   $ hg log -G --template '{rev} {desc}'
   @  3 a1-amend
   |
   | o  1 a1
   |/
   o  0 a0
   
 
 Before the fix, the copy information was lost.
   $ hg status --copies --rev 0
   A a2
     a0
   R a0
   $ cd ..
 
 Check that amend properly preserve rename from directory rename (issue-4516)
 
 If a parent of the merge renames a full directory, any files added to the old
 directory in the other parent will be renamed to the new directory. For some
 reason, the rename metadata was when amending such merge. This test ensure we
 do not regress. We have a dedicated repo because it needs a setup with renamed
 directory)

 Test amend with file inclusion options
 --------------------------------------
 
 These tests ensure that we are always amending some files that were part of the
 pre-amend commit. We want to test that the remaining files in the pre-amend
 commit were not changed in the amended commit. We do so by performing a diff of
 the amended commit against its parent commit.

   $ hg debugp1copies -r 1
   x -> y
 Incorrectly doesn't show the rename
   $ hg debugpathcopies 0 1
 
 Copy a file onto another file with same content. If metadata is stored in changeset, this does not
 produce a new filelog entry. The changeset's "files" entry should still list the file.
   $ newrepo
   $ echo x > x
   $ echo x > x2
   $ hg ci -Aqm 'add x and x2 with same content'
   $ hg cp -f x x2
   $ hg ci -m 'copy x onto x2'

 Copy a file, then delete destination, then copy again. This does not create a new filelog entry.

   o  0 add x
      x
   $ hg debugpathcopies 0 3
 
 Copy x to y, then remove y, then add back y. With copy metadata in the changeset, this could easily
 end up reporting y as copied from x (if we don't unmark it as a copy when it's removed).
   $ newrepo

   $ hg ci -Aqm 'add x'
   $ hg mv x y

   o  1 rename x to y
   |  x y
   o  0 add x
      x
   $ hg debugp1copies -r 3
   $ hg debugpathcopies 0 3
 
 Copy x to z, then remove z, then copy x2 (same content as x) to z. With copy metadata in the
 changeset, the two copies here will have the same filelog entry, so ctx['z'].introrev() might point
 to the first commit that added the file. We should still report the copy as being from x2.
   $ newrepo
   $ echo x > x
   $ echo x > x2
   $ hg ci -Aqm 'add x and x2 with same content'

 Graft from behind a move or rename
 ==================================
 
 NOTE: This is affected by issue5343, and will need updating when it's fixed
 
 Consider this topology for a regular graft:
 
 o c1
 |
 | o c2
 | |
 | o ca # stands for "common ancestor"
 |/
 o cta # stands for "common topological ancestor"
 
 Note that in issue5343, ca==cta.
 
 The following table shows the possible cases. Here, "x->y" and, equivalently,
 "y<-x", where x is an ancestor of y, means that some copy happened from x to y.
 
 name | c1<-cta | cta<->ca | ca->c2
 A.0  |         |          |
 A.1  |    X    |          |
 A.2  |         |     X    |
 A.3  |         |          |   X
 A.4  |    X    |     X    |
 A.5  |    X    |          |   X
 A.6  |         |     X    |   X
 A.7  |    X    |     X    |   X
 
 A.0 is trivial, and doesn't need copy tracking.
 For A.1, a forward rename is recorded in the c1 pass, to be followed later.
 In A.2, the rename is recorded in the c2 pass and followed backwards.
 A.3 is recorded in the c2 pass as a forward rename to be duplicated on target.
 In A.4, both passes of checkcopies record incomplete renames, which are
 then joined in mergecopies to record a rename to be followed.
 In A.5 and A.7, the c1 pass records an incomplete rename, while the c2 pass
 records an incomplete divergence. The incomplete rename is then joined to the
 appropriate side of the incomplete divergence, and the result is recorded as a
 divergence. The code doesn't distinguish at all between these two cases, since
 the end result of them is the same: an incomplete divergence joined with an
 incomplete rename into a divergence.
 Finally, A.6 records a divergence entirely in the c2 pass.
 
 A.4 has a degenerate case a<-b<-a->a, where checkcopies isn't needed at all.
 A.5 has a special case a<-b<-b->a, which is treated like a<-b->a in a merge.
 A.5 has issue5343 as a special case.
 A.6 has a special case a<-a<-b->a. Here, checkcopies will find a spurious
 incomplete divergence, which is in fact complete. This is handled later in
 mergecopies.
 A.7 has 4 special cases: a<-b<-a->b (the "ping-pong" case), a<-b<-c->b,
 a<-b<-a->c and a<-b<-c->a. Of these, only the "ping-pong" case is interesting,
 the others are fairly trivial (a<-b<-c->b and a<-b<-a->c proceed like the base
 case, a<-b<-c->a is treated the same as a<-b<-b->a).
 
 f5a therefore tests the "ping-pong" rename case, where a file is renamed to the
 same name on both branches, then the rename is backed out on one branch, and
 the backout is grafted to the other branch. This creates a challenging rename
 sequence of a<-b<-a->b in the graft target, topological CA, graft CA and graft
 source, respectively. Since rename detection will run on the c1 side for such a
 sequence (as for technical reasons, we split the c1 and c2 sides not at the
 graft CA, but rather at the topological CA), it will pick up a false rename,
 and cause a spurious merge conflict. This false rename is always exactly the
 reverse of the true rename that would be detected on the c2 side, so we can
 correct for it by detecting this condition and reversing as necessary.
 
 First, set up the repository with commits to be grafted

 Grafting of plain changes correctly detects that 3 and 5 should be skipped:
 
   $ hg up -qCr 4
   $ hg graft --tool :local -r 2::5
   skipping already grafted revision 3:ca093ca2f1d9 (was grafted from 1:13ec5badbf2a)
   skipping already grafted revision 5:43e9eb70dab0 (was grafted from 4:6c9a1289e5f1)
   grafting 2:42127f193bcd "b"
 
 Extending the graft range to include a (skipped) merge of 3 will not prevent us from
 also detecting that both 3 and 5 should be skipped:
 
   $ hg up -qCr 4
   $ hg graft --tool :local -r 2::7
   skipping ungraftable merge revision 6
   skipping already grafted revision 3:ca093ca2f1d9 (was grafted from 1:13ec5badbf2a)
   skipping already grafted revision 5:43e9eb70dab0 (was grafted from 4:6c9a1289e5f1)
   grafting 2:42127f193bcd "b"

 Additional tricky linkrev case
 ------------------------------
 
 If the first file revision after the diff base has a linkrev pointing to a
 changeset on another branch with a revision lower that the diff base, we can
 jump past the copy detection limit and fail to detect the rename.
 
   $ hg init diffstoplinkrev
   $ cd diffstoplinkrev
 
   $ touch f
   $ hg ci -Aqm 'empty f'
 
 Make a simple change
 
   $ echo change > f
   $ hg ci -m 'change f'
 
 Make a rename because we want to track renames. It is also important that the
 faulty linkrev is not only the "start" commit to ensure the linkrev will be
 used.
 
   $ hg mv f renamed
   $ hg ci -m renamed
 
 Make a second branch, we use a named branch to create a simple commit
 that does not touch f.
 
   $ hg up -qr 'desc(empty)'
   $ hg branch -q dev
   $ hg ci -Aqm dev
 
 Graft the initial change and the rename. As f was untouched, we reuse the same
 entry and the linkrev point to the older branch.
 
   $ hg graft -q 'desc(change)'
   $ hg graft -q 'desc(renamed)'
 
   $ hg log -G -T '{rev} {desc}'
   @  5 renamed
   |
   o  4 change f
   |
   o  3 dev
   |
   | o  2 renamed
   | |
   | o  1 change f
   |/
   o  0 empty f
   
 
 The copy tracking should still reach rev 3 (branch creation).
 accessing the parent of 5 (renamed) should not jump use to revision 1.
