absorb: preserve changesets which were already empty

Most commands in Mercurial (commit, rebase, absorb itself) don’t create empty
changesets or drop them if they become empty. If there’s a changeset that’s
empty, it must be a deliberate choice of the user. At least it shouldn’t be
absorb’s responsibility to prune them. The fact that changesets that became
empty during absorb are pruned, is unaffected by this.

This case was found while writing patches which make it possible to configure
absorb and rebase to not drop empty changesets. Even without having such config
set, I think it’s valuable to preserve changesets which were already empty.

log template:

 (behaves as a {name: path-string} dict by default)

  $ hg log -rnull -T '{peerurls}\n'
  dupe=$TESTTMP/b#tip expand=$TESTTMP/a/$SOMETHING/bar
  $ hg log -rnull -T '{join(peerurls, "\n")}\n'
  dupe=$TESTTMP/b#tip
  expand=$TESTTMP/a/$SOMETHING/bar
  $ hg log -rnull -T '{peerurls % "{name}: {url}\n"}'
  dupe: $TESTTMP/b#tip
  expand: $TESTTMP/a/$SOMETHING/bar
  $ hg log -rnull -T '{get(peerurls, "dupe")}\n'
  $TESTTMP/b#tip

 (sub options can be populated by map/dot operation)

  $ hg log -rnull \
  > -T '{get(peerurls, "dupe") % "url: {url}\npushurl: {pushurl}\n"}'
  url: $TESTTMP/b#tip
  pushurl: https://example.com/dupe
  $ hg log -rnull -T '{peerurls.dupe.pushurl}\n'
  https://example.com/dupe

 (in JSON, it's a dict of urls)

  $ hg log -rnull -T '{peerurls|json}\n' | sed 's|\\\\|/|g'
  {"dupe": "$TESTTMP/b#tip", "expand": "$TESTTMP/a/$SOMETHING/bar"}

password should be masked in plain output, but not in machine-readable/template
output:

  $ echo 'insecure = http://foo:[e-mail]/' >> .hg/hgrc
  $ hg paths insecure
  http://foo:***@example.com/
  $ hg paths -Tjson insecure
  [
   {
    "name": "insecure",
    "url": "http://foo:[e-mail]/"
   }
  ]
  $ hg log -rnull -T '{get(peerurls, "insecure")}\n'
  http://foo:[e-mail]/

zeroconf wraps ui.configitems(), which shouldn't crash at least:

  $ hg paths --config extensions.zeroconf=
  dupe = $TESTTMP/b#tip
  dupe:pushurl = https://example.com/dupe
  expand = $TESTTMP/a/$SOMETHING/bar
  insecure = http://foo:***@example.com/

  $ cd ..

sub-options for an undeclared path are ignored

  $ hg init suboptions
  $ cd suboptions

  $ cat > .hg/hgrc << EOF
  > [paths]
  > path0 = https://example.com/path0
  > path1:pushurl = https://example.com/path1
  > EOF
  $ hg paths
  path0 = https://example.com/path0

unknown sub-options aren't displayed

  $ cat > .hg/hgrc << EOF
  > [paths]
  > path0 = https://example.com/path0
  > path0:foo = https://example.com/path1
  > EOF

  $ hg paths
  path0 = https://example.com/path0

:pushurl must be a URL

  $ cat > .hg/hgrc << EOF
  > [paths]
  > default = /path/to/nothing
  > default:pushurl = /not/a/url
  > EOF

  $ hg paths
  (paths.default:pushurl not a URL; ignoring)
  default = /path/to/nothing

#fragment is not allowed in :pushurl

  $ cat > .hg/hgrc << EOF
  > [paths]
  > default = https://example.com/repo
  > invalid = https://example.com/repo
  > invalid:pushurl = https://example.com/repo#branch

  $ hg paths
