subrepo: share instead of clone if the parent repo is shared (issue5675) (BC) Previously, only the top level repo was shared, and then any subrepos were cloned on demand. This is problematic because commits to the parent repo would write an updated .hgsubstate to the share source, but the corresponding subrepo commit would be stuck in the local subrepo. That would prevent an update in the source repo. We already go to great lengths to avoid having inconsistent repos (e.g., `hg push -r rev` will push _everything_ in a subrepo, even if it isn't referenced in one of the parent's outgoing commits). Therefore, this seems like a bug fix, and there's no option to get the old behavior. I can't imagine the previous behavior was useful to anybody. There shouldn't be an issue with svn, since it is centralized. Maybe --git-dir can be used for git subrepos, but I'll leave that to someone more familiar with git. An integer was previously being implicitly returned from commands.share(), which caused dispatch() to start crashing when changing over to returning the shared repo. All error paths appear to raise, so this can be hardcoded to success. The clone command checks for 'is None' in a similar pattern, but since hg.clone() always returns a tuple, that seems wrong? .. fix:: Issue 5675 Creating a share of a repository with a Mercurial subrepository will now share the subrepository. and .. bc:: Mercurial subrepositories are now shared instead of cloned when the parent repository is shared. This prevents dangling subrepository references in the share source. Previously shared repositories with cloned subrepositories will continue to function unchanged.

Create a repository:

  $ hg config
  devel.all-warnings=true
  devel.default-date=0 0
  extensions.fsmonitor= (fsmonitor !)
  largefiles.usercache=$TESTTMP/.cache/largefiles (glob)
  ui.slash=True
  ui.interactive=False
  ui.mergemarkers=detailed
  ui.promptecho=True
  web.address=localhost
  web\.ipv6=(?:True|False) (re)
  $ hg init t
  $ cd t

Prepare a changeset:

  $ echo a > a
  $ hg add a

  $ hg status
  A a

Writes to stdio succeed and fail appropriately

#if devfull
  $ hg status 2>/dev/full
  A a

  $ hg status >/dev/full
  abort: No space left on device
  [255]
#endif

#if devfull no-chg
  $ hg status >/dev/full 2>&1
  [1]

  $ hg status ENOENT 2>/dev/full
  [1]
#endif

#if devfull chg
  $ hg status >/dev/full 2>&1
  [255]

  $ hg status ENOENT 2>/dev/full
  [255]
#endif

  $ hg commit -m test

This command is ancient:

  $ hg history
  changeset:   0:acb14030fe0a
  tag:         tip
  user:        test
  date:        Thu Jan 01 00:00:00 1970 +0000
  summary:     test
  

Verify that updating to revision 0 via commands.update() works properly

  $ cat <<EOF > update_to_rev0.py
  > from mercurial import ui, hg, commands
  > myui = ui.ui.load()
  > repo = hg.repository(myui, path='.')
  > commands.update(myui, repo, rev=0)
  > EOF
  $ hg up null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ $PYTHON ./update_to_rev0.py
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg identify -n
  0


Poke around at hashes:

  $ hg manifest --debug
  b789fdd96dc2f3bd229c1dd8eedf0fc60e2b68e3 644   a

  $ hg cat a
  a

Verify should succeed:

  $ hg verify
  checking changesets
  checking manifests
  crosschecking files in changesets and manifests
  checking files
  1 files, 1 changesets, 1 total revisions

At the end...

  $ cd ..
