archive: support 'wdir()'

This is a step toward replacing the extdiff internals with archive, in order to
support 'extdiff -S'.  Only Mercurial subrepos are supported for now.

If a file is missing from the filesystem, it is silently skipped.  Perhaps it
should warn, but it cannot abort when working with extdiff because deleting a
file is a legitimate diff.

Preparing the subrepository 'sub2'

  $ hg init sub2
  $ echo sub2 > sub2/sub2
  $ hg add -R sub2
  adding sub2/sub2 (glob)
  $ hg commit -R sub2 -m "sub2 import"

Preparing the 'sub1' repo which depends on the subrepo 'sub2'

  $ hg init sub1
  $ echo sub1 > sub1/sub1
  $ echo "sub2 = ../sub2" > sub1/.hgsub
  $ hg clone sub2 sub1/sub2
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg add -R sub1
  adding sub1/.hgsub (glob)
  adding sub1/sub1 (glob)
  $ hg commit -R sub1 -m "sub1 import"

Preparing the 'main' repo which depends on the subrepo 'sub1'

  $ hg init main
  $ echo main > main/main
  $ echo "sub1 = ../sub1" > main/.hgsub
  $ hg clone sub1 main/sub1
  updating to branch default
  cloning subrepo sub2 from $TESTTMP/sub2
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg add -R main
  adding main/.hgsub (glob)
  adding main/main (glob)
  $ hg commit -R main -m "main import"

Cleaning both repositories, just as a clone -U

  $ hg up -C -R sub2 null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg up -C -R sub1 null
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ hg up -C -R main null
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ rm -rf main/sub1
  $ rm -rf sub1/sub2

Clone main

  $ hg --config extensions.largefiles= clone main cloned
  updating to branch default
  cloning subrepo sub1 from $TESTTMP/sub1
  cloning subrepo sub1/sub2 from $TESTTMP/sub2 (glob)
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved

Largefiles is NOT enabled in the clone if the source repo doesn't require it
  $ cat cloned/.hg/hgrc
  # example repository config (see "hg help config" for more info)
  [paths]
  default = $TESTTMP/main (glob)
  
  # path aliases to other clones of this repo in URLs or filesystem paths
  # (see "hg help config.paths" for more info)
  #
  # default-push = ssh://[e-mail]/hg/jdoes-fork
  # my-fork      = ssh://[e-mail]/hg/jdoes-fork
  # my-clone     = /home/jdoe/jdoes-clone
  
  [ui]
  # name and email (local to this repository, optional), e.g.
  # username = Jane Doe <[e-mail]>

Checking cloned repo ids

  $ printf "cloned " ; hg id -R cloned
  cloned 7f491f53a367 tip
  $ printf "cloned/sub1 " ; hg id -R cloned/sub1
  cloned/sub1 fc3b4ce2696f tip
  $ printf "cloned/sub1/sub2 " ; hg id -R cloned/sub1/sub2
  cloned/sub1/sub2 c57a0840e3ba tip

debugsub output for main and sub1

  $ hg debugsub -R cloned
  path sub1
   source   ../sub1
   revision fc3b4ce2696f7741438c79207583768f2ce6b0dd
  $ hg debugsub -R cloned/sub1

   source   ../sub2
   revision c57a0840e3badd667ef3c3ef65471609acb2ba3c

Modifying deeply nested 'sub2'

  $ echo modified > cloned/sub1/sub2/sub2
  $ hg commit --subrepos -m "deep nested modif should trigger a commit" -R cloned
  committing subrepository sub1
  committing subrepository sub1/sub2 (glob)

Checking modified node ids

  $ printf "cloned " ; hg id -R cloned

  $ printf "cloned/sub1/sub2 " ; hg id -R cloned/sub1/sub2
  cloned/sub1/sub2 53dd3430bcaf tip

debugsub output for main and sub1

  $ hg debugsub -R cloned
  path sub1
   source   ../sub1
   revision 2ecb03bf44a94e749e8669481dd9069526ce7cb9

  path sub2
   source   ../sub2
   revision 53dd3430bcaf5ab4a7c48262bcad6d441f510487

Check that deep archiving works

  $ cd cloned
  $ echo 'test' > sub1/sub2/test.txt
  $ hg --config extensions.largefiles=! add sub1/sub2/test.txt
  $ mkdir sub1/sub2/folder
  $ echo 'subfolder' > sub1/sub2/folder/test.txt
  $ hg ci -ASm "add test.txt"
  adding sub1/sub2/folder/test.txt
  committing subrepository sub1
  committing subrepository sub1/sub2 (glob)

.. but first take a detour through some deep removal testing

  $ hg remove -S -I 're:.*.txt' .
  removing sub1/sub2/folder/test.txt (glob)
  removing sub1/sub2/test.txt (glob)
  $ hg status -S
  R sub1/sub2/folder/test.txt
  R sub1/sub2/test.txt
  $ hg update -Cq
  $ hg remove -I 're:.*.txt' sub1
  $ hg status -S
  $ hg remove sub1/sub2/folder/test.txt
  $ hg remove sub1/.hgsubstate
  $ mv sub1/.hgsub sub1/x.hgsub
  $ hg status -S
  warning: subrepo spec file 'sub1/.hgsub' not found (glob)

  $ mv sub1/x.hgsub sub1/.hgsub
  $ hg update -Cq
  $ touch sub1/foo
  $ hg forget sub1/sub2/folder/test.txt
  $ rm sub1/sub2/test.txt

  adding ../sub1/foo (glob)
  adding bar/abc (glob)
  $ cd ..
  $ hg status -S
  A foo/bar/abc
  A sub1/foo
  R sub1/sub2/test.txt

Archive wdir() with subrepos
  $ hg rm main
  $ hg archive -S -r 'wdir()' ../wdir
  $ diff -r . ../wdir | grep -v '\.hg$'
  Only in ../wdir: .hg_archival.txt

  $ find ../wdir -type f | sort

  ../wdir/sub1/foo
  ../wdir/sub1/sub1
  ../wdir/sub1/sub2/folder/test.txt

Attempting to archive 'wdir()' with a missing file is handled gracefully
  $ rm sub1/sub1
  $ rm -r ../wdir
  $ hg archive -v -S -r 'wdir()' ../wdir
  $ find ../wdir -type f | sort
