revlog: directly use the Struct object for related operation

The Struct object has all the piece we needs, so no need to duplicate
information on the revlog itself.

prepare repo1

  $ hg init repo1
  $ cd repo1
  $ echo a > a
  $ hg commit -A -m'init'
  adding a

share it

  $ cd ..
  $ hg share repo1 repo2
  updating working directory
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

share shouldn't have a store dir

  $ cd repo2
  $ test -d .hg/store
  [1]
  $ hg root -Tjson | sed 's|\\\\|\\|g'
  [
   {
    "hgpath": "$TESTTMP/repo2/.hg",
    "reporoot": "$TESTTMP/repo2",
    "storepath": "$TESTTMP/repo1/.hg/store"
   }
  ]

share shouldn't have a full cache dir, original repo should

  $ hg branches
  default                        0:d3873e73d99e
  $ hg tags
  tip                                0:d3873e73d99e
  $ test -d .hg/cache
  [1]
  $ ls -1 .hg/wcache || true
  checkisexec (execbit !)
  checklink (symlink !)
  checklink-target (symlink !)
  manifestfulltextcache (reporevlogstore !)
  $ ls -1 ../repo1/.hg/cache
  branch2-served
  rbc-names-v1
  rbc-revs-v1
  tags2-visible

Cloning a shared repo should pick up the full cache dir on the other hand.

  $ hg clone . ../repo2-clone
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ ls -1 ../repo2-clone/.hg/cache
  branch2-base
  branch2-immutable
  branch2-served
  branch2-served.hidden
  branch2-visible
  branch2-visible-hidden
  hgtagsfnodes1
  rbc-names-v1
  rbc-revs-v1
  tags2
  tags2-served
  tags2-visible

Some sed versions appends newline, some don't, and some just fails

  $ cat .hg/sharedpath; echo
  $TESTTMP/repo1/.hg

trailing newline on .hg/sharedpath is ok
  $ hg tip -q
  0:d3873e73d99e
  $ echo '' >> .hg/sharedpath
  $ cat .hg/sharedpath
  $TESTTMP/repo1/.hg
  $ hg tip -q
  0:d3873e73d99e

commit in shared clone

  $ echo a >> a
  $ hg commit -m'change in shared clone'

Cloning a shared repo via bundle2 results in a non-shared clone

  $ cd ..
  $ hg clone -q --stream --config ui.ssh="\"$PYTHON\" \"$TESTDIR/dummyssh\"" ssh://user@dummy/`pwd`/repo2 cloned-via-bundle2

  $ test -f .hg/sharedpath

  abort: this is not a shared repo

check that a change does not propagate

non largefiles repos won't enable largefiles

test shared clones using relative paths work

  $ mkdir thisdir
  $ hg init thisdir/orig
  $ hg share -U thisdir/orig thisdir/abs
  $ hg share -U --relative thisdir/abs thisdir/rel
  $ cat thisdir/rel/.hg/sharedpath
  ../../orig/.hg (no-eol)
  $ grep shared thisdir/*/.hg/requires
  thisdir/abs/.hg/requires:shared
  thisdir/rel/.hg/requires:relshared
  thisdir/rel/.hg/requires:shared

test that relative shared paths aren't relative to $PWD

  $ cd thisdir
  $ hg -R rel root
  $TESTTMP/thisdir/rel
  $ cd ..

now test that relative paths really are relative, survive across
renames and changes of PWD

  $ hg -R thisdir/abs root
  $TESTTMP/thisdir/abs
  $ hg -R thisdir/rel root
  $TESTTMP/thisdir/rel
  $ mv thisdir thatdir
  $ hg -R thatdir/abs root
  abort: .hg/sharedpath points to nonexistent directory $TESTTMP/thisdir/orig/.hg

  $ hg -R thatdir/rel root

test unshare relshared repo

  $ grep shared .hg/requires

  $ hg unshare

  $ rm -r thatdir

Demonstrate buggy behavior around requirements validation
See comment in localrepo.py:makelocalrepository() for more.

  $ hg init sharenewrequires

  0 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ cat >> sharenewrequires/.hg/requires << EOF

We cannot open the repo with the unknown requirement

  $ hg -R sharenewrequires status
  abort: repository requires features unknown to this Mercurial: missing-requirement
  (see https://mercurial-scm.org/wiki/MissingRequirement for more information)

BUG: we don't get the same error when opening the shared repo pointing to it

  $ hg -R shareoldrequires status

Explicitly kill daemons to let the test exit on Windows

  $ killdaemons.py

Test sharing a repository which was created with store requirement disable

  $ hg init nostore --config format.usestore=false
  ignoring enabled 'format.use-share-safe' config because it is incompatible with disabled 'format.usestore' config (safe !)
  $ hg share nostore sharednostore
