ancestor: faster algorithm for difference of ancestor sets

One of the major reasons rebase is slow in large repositories is
the computation of the detach set: the set of ancestors of the
changesets to rebase not in the destination parent. This is currently
done via a revset that does two walks all the way to the root of
the DAG. Instead of doing that, to find ancestors of a set <revs>
not in another set <common> we walk up the tree in reverse revision
number order, maintaining sets of nodes visited from <revs>, <common>
or both.

For the common case where the sets are close both topologically and
in revision number (relative to repository size), this has been
found to speed up rebase by around 15-20%. When the nodes are farther
apart and the DAG is highly branching, it is harder to say which
would win.

Here's how long computing the detach set takes in a linear repository
with over 400000 changesets, rebasing near tip:

Rebasing across 4 changesets
Revset method: 2.2s
New algorithm: 0.00015s

Rebasing across 250 changesets
Revset method: 2.2s
New algorithm: 0.00069s

Rebasing across 10000 changesets
Revset method: 2.4s
New algorithm: 0.019s

Create the repo with a couple of revisions of both large and normal
files, testing that status correctly shows largefiles and that summary output
is correct.

  $ hg init a
  $ cd a
  $ mkdir sub
  $ echo normal1 > normal1
  $ echo normal2 > sub/normal2
  $ echo large1 > large1
  $ echo large2 > sub/large2
  $ hg add normal1 sub/normal2
  $ hg add --large large1 sub/large2
  $ hg commit -m "add files"
  Invoking status precommit hook

  A normal1
  A sub/large2
  A sub/normal2
  $ echo normal11 > normal1
  $ echo normal22 > sub/normal2
  $ echo large11 > large1
  $ echo large22 > sub/large2
  $ hg commit -m "edit files"

  parent: 1:ce8896473775 tip
   edit files
  branch: default
  commit: (clean)
  update: (current)
  largefiles: (no remote repo)

Commit preserved largefile contents.

  $ cat normal1
  normal11
  $ cat large1
  large11
  $ cat sub/normal2
  normal22
  $ cat sub/large2

Test status, subdir and unknown files

  $ echo unknown > sub/unknown
  $ hg st --all
  ? sub/unknown
  C large1
  C normal1
  C sub/large2
  C sub/normal2
  $ hg st --all sub
  ? sub/unknown
  C sub/large2
  C sub/normal2
  $ rm sub/unknown

Test exit codes for remove warning cases (modified and still exiting)

  $ hg remove -A large1
  not removing large1: file still exists (use forget to undo)
  [1]
  $ echo 'modified' > large1
  $ hg remove large1
  not removing large1: file is modified (use forget to undo)

  $ hg up -Cq

Remove both largefiles and normal files.

  $ hg remove normal1 large1

  $ hg commit -m "remove files"
  Invoking status precommit hook

  $ ls
  sub
  $ echo "testlargefile" > large1-test
  $ hg add --large large1-test
  $ hg st

  $ hg rm large1-test

  $ hg st

  $ hg forget large1-test
  $ hg st
  ? large1-test
  $ hg remove large1-test
  not removing large1-test: file is untracked

  $ hg forget large1-test
  not removing large1-test: file is already untracked

  $ rm large1-test

Copy both largefiles and normal files (testing that status output is correct).

  $ hg cp sub/normal2 normal1

  Invoking status precommit hook
  A large1
  A normal1
  $ cat normal1

Test moving largefiles and verify that normal files are also unaffected.

  $ hg mv normal1 normal3
  $ hg mv large1 large3
  $ hg mv sub/normal2 sub/normal4
  $ hg mv sub/large2 sub/large4
  $ hg commit -m "move files"

  $ cd ../a
  $ echo normal33 > normal3
  $ echo large33 > large3
  $ echo normal44 > sub/normal4
  $ echo large44 > sub/large4

Corner cases for adding largefiles.

  $ echo large5 > large5
  $ hg add --large large5
  $ hg add --large large5

  $ mkdir sub2
  $ echo large6 > sub2/large6
  $ echo large7 > sub2/large7
  $ hg add --large sub2
  adding sub2/large6 as a largefile (glob)
  adding sub2/large7 as a largefile (glob)
  $ hg st
  M large3
  A large5
  A sub2/large6
  A sub2/large7

Test "hg status" with combination of 'file pattern' and 'directory
pattern' for largefiles:

  $ hg status sub2/large6 sub2
  A sub2/large6
  A sub2/large7

Config settings (pattern **.dat, minsize 2 MB) are respected.

  $ echo testdata > test.dat
  $ dd bs=1k count=2k if=/dev/zero of=reallylarge > /dev/null 2> /dev/null
  $ hg add
  adding reallylarge as a largefile
  adding test.dat as a largefile

Test that minsize and --lfsize handle float values;
also tests that --lfsize overrides largefiles.minsize.
(0.250 MB = 256 kB = 262144 B)

  $ dd if=/dev/zero of=ratherlarge bs=1024 count=256 > /dev/null 2> /dev/null
  $ dd if=/dev/zero of=medium bs=1024 count=128 > /dev/null 2> /dev/null
  $ hg --config largefiles.minsize=.25 add
  adding ratherlarge as a largefile
  adding medium
  $ hg forget medium
  $ hg --config largefiles.minsize=.25 add --lfsize=.125
  adding medium as a largefile
  $ dd if=/dev/zero of=notlarge bs=1024 count=127 > /dev/null 2> /dev/null
  $ hg --config largefiles.minsize=.25 add --lfsize=.125
  adding notlarge
  $ hg forget notlarge

Test forget on largefiles.

dir after a purge.

  $ hg purge --all

Test addremove: verify that files that should be added as largfiles are added as
such and that already-existing largfiles are not added as normal files by
accident.

  $ rm normal3
  $ rm sub/large4
  $ echo "testing addremove with patterns" > testaddremove.dat

Add a normal file to the subrepo, then test archiving

  $ echo 'normal file' > subrepo/normal.txt
  $ hg -R subrepo add subrepo/normal.txt

Lock in subrepo, otherwise the change isn't archived

Test archiving a revision that references a subrepo that is not yet
cloned (see test-subrepo-recursion.t):

  $ hg clone -U . ../empty
  $ cd ../empty
  $ hg archive --subrepos -r tip ../archive.tar.gz
  cloning subrepo subrepo from $TESTTMP/statusmatch/subrepo
  $ cd ..

Test that addremove picks up largefiles prior to the initial commit (issue3541)

  $ hg init addrm2
  $ cd addrm2
  $ touch large.dat
  $ touch large2.dat
  $ touch normal
  $ hg add --large large.dat
  $ hg addremove -v
  adding large2.dat as a largefile
  adding normal

Test that forgetting all largefiles reverts to islfilesrepo() == False
(addremove will add *.dat as normal files now)
  $ hg forget large.dat
  $ hg forget large2.dat
  $ hg addremove -v
  adding large.dat
  adding large2.dat

Test commit's addremove option prior to the first commit
  $ hg forget large.dat
  $ hg forget large2.dat
  $ hg add --large large.dat
  $ hg ci -Am "commit"

check messages when no remote repository is specified:
"no remote repo" route for "hg outgoing --large" is not tested here,
because it can't be reproduced easily.
