prepare source repo

  $ hg init source
  $ cd source
  $ cat .hg/requires
  exp-sharesafe
  $ cat .hg/store/requires
  dotencode
  fncache
  generaldelta
  revlogv1
  sparserevlog
  store
  $ hg debugrequirements
  dotencode
  exp-sharesafe
  fncache
  generaldelta
  revlogv1
  sparserevlog
  store

  $ echo a > a
  $ hg ci -Aqm "added a"
  $ echo b > b
  $ hg ci -Aqm "added b"

  $ HGEDITOR=cat hg config --shared
  abort: repository is not shared; can't use --shared
  [10]
  $ cd ..

Create a shared repo and check the requirements are shared and read correctly
  $ hg share source shared1
  updating working directory
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd shared1
  $ cat .hg/requires
  exp-sharesafe
  shared

  $ hg debugrequirements -R ../source
  dotencode
  exp-sharesafe
  fncache
  generaldelta
  revlogv1
  sparserevlog
  store

  $ hg debugrequirements
  dotencode
  exp-sharesafe
  fncache
  generaldelta
  revlogv1
  shared
  sparserevlog
  store

  $ echo c > c
  $ hg ci -Aqm "added c"

Check that config of the source repository is also loaded

  $ hg showconfig ui.curses
  [1]

  $ echo "[ui]" >> ../source/.hg/hgrc
  $ echo "curses=true" >> ../source/.hg/hgrc

  $ hg showconfig ui.curses
  true

Test that extensions of source repository are also loaded

  $ hg debugextensions
  share
  $ hg extdiff -p echo
  hg: unknown command 'extdiff'
  'extdiff' is provided by the following extension:
  
      extdiff       command to allow external programs to compare revisions
  
  (use 'hg help extensions' for information on enabling extensions)
  [255]

  $ echo "[extensions]" >> ../source/.hg/hgrc
  $ echo "extdiff=" >> ../source/.hg/hgrc

  $ hg debugextensions -R ../source
  extdiff
  share
  $ hg extdiff -R ../source -p echo

BROKEN: the command below will not work if config of shared source is not loaded
on dispatch but debugextensions says that extension
is loaded
  $ hg debugextensions
  extdiff
  share

  $ hg extdiff -p echo

However, local .hg/hgrc should override the config set by share source

  $ echo "[ui]" >> .hg/hgrc
  $ echo "curses=false" >> .hg/hgrc

  $ hg showconfig ui.curses
  false

  $ HGEDITOR=cat hg config --shared
  [ui]
  curses=true
  [extensions]
  extdiff=

  $ HGEDITOR=cat hg config --local
  [ui]
  curses=false

Testing that hooks set in source repository also runs in shared repo

  $ cd ../source
  $ cat <<EOF >> .hg/hgrc
  > [extensions]
  > hooklib=
  > [hooks]
  > pretxnchangegroup.reject_merge_commits = \
  >   python:hgext.hooklib.reject_merge_commits.hook

  $ cd ..
  $ hg clone source cloned

  $ cd cloned
  $ hg up 0

  $ echo bar > bar
  $ hg ci -Aqm "added bar"
  $ hg merge

Test that if share source config is untrusted, we dont read it

  $ cd ../shared1

  $ cat << EOF > $TESTTMP/untrusted.py
  > from mercurial import scmutil, util
  > def uisetup(ui):
  >     class untrustedui(ui.__class__):
  >         def _trusted(self, fp, f):
  >             if util.normpath(fp.name).endswith(b'source/.hg/hgrc'):
  >                 return False
  >             return super(untrustedui, self)._trusted(fp, f)
  >     ui.__class__ = untrustedui
  > EOF

  $ hg showconfig hooks
  hooks.pretxnchangegroup.reject_merge_commits=python:hgext.hooklib.reject_merge_commits.hook

  $ hg showconfig hooks --config extensions.untrusted=$TESTTMP/untrusted.py
  [1]

Update the source repository format and check that shared repo works

  $ cd ../source

Disable zstd related tests because its not present on pure version
#if zstd
  $ echo "[format]" >> .hg/hgrc
  $ echo "revlog-compression=zstd" >> .hg/hgrc

  $ hg debugupgraderepo --run -q
  upgrade will perform the following actions:
  
  requirements
     preserved: dotencode, exp-sharesafe, fncache, generaldelta, revlogv1, sparserevlog, store
     added: revlog-compression-zstd
  
  $ hg log -r .
  changeset:   1:5f6d8a4bf34a
  user:        test
  date:        Thu Jan 01 00:00:00 1970 +0000
  summary:     added b
  
#endif
  $ echo "[format]" >> .hg/hgrc
  $ echo "use-persistent-nodemap=True" >> .hg/hgrc

  $ hg debugupgraderepo --run -q -R ../shared1
  abort: cannot upgrade repository; unsupported source requirement: shared
  [255]

  $ hg debugupgraderepo --run -q
  upgrade will perform the following actions:
  
  requirements
     preserved: dotencode, exp-sharesafe, fncache, generaldelta, revlogv1, sparserevlog, store (no-zstd !)
     preserved: dotencode, exp-sharesafe, fncache, generaldelta, revlog-compression-zstd, revlogv1, sparserevlog, store (zstd !)
     added: persistent-nodemap
  
  $ hg log -r .

  summary:     added b
  

Shared one should work
  $ cd ../shared1
  $ hg log -r .
  changeset:   2:155349b645be
  tag:         tip
  user:        test
  date:        Thu Jan 01 00:00:00 1970 +0000
  summary:     added c
  

Testing that nonsharedrc is loaded for source and not shared

  $ cd ../source
  $ touch .hg/hgrc-not-shared
  $ echo "[ui]" >> .hg/hgrc-not-shared
  $ echo "traceback=true" >> .hg/hgrc-not-shared

  $ hg showconfig ui.traceback
  true

  $ HGEDITOR=cat hg config --non-shared
  [ui]
  traceback=true

  $ cd ../shared1
  $ hg showconfig ui.traceback
  [1]

Unsharing works

  $ hg unshare

Test that source config is added to the shared one after unshare, and the config
of current repo is still respected over the config which came from source config
  $ cd ../cloned
  $ hg push ../shared1
