topic: internal config option to fix hg pick behavior (issue6406)

After some consideration, hg pick was made to always use current topic (and
topic namespace), even if it's not set, in which case the resulting changeset
will not have any topic.

Previously the intended behavior was to only update topic if there was an
active topic, and not touch commit extras at all otherwise. That wasn't ideal,
since pick doesn't change active topic, and amending the just-picked commit
would unset its topic without clear user's intent to do so and to their
surprise.

Limiting topic namespaces during exchange based on a config option

  $ . "$TESTDIR/testlib/common.sh"

  $ cat >> $HGRCPATH << EOF
  > [extensions]
  > topic =
  > [phases]
  > publish = no
  > [ui]
  > ssh = "$PYTHON" "$RUNTESTDIR/dummyssh"
  > [devel]
  > tns-report-transactions = pull
  > [ui]
  > logtemplate = "{rev}: {desc} {fqbn} ({phase})\n"
  > EOF

  $ hg init orig

#testcases local ssh http

#if http
  $ hg serve -R orig -n test -p $HGPORT -d --pid-file=hg.pid -A access.log -E errors.log
  $ cat hg.pid >> $DAEMON_PIDS
#endif

we advertise the new capability, including during local exchange

#if local
  $ hg debugcapabilities orig | grep topics
    ext-topics-publish=none
    ext-topics-tns-heads
    topics
    topics-namespaces
#endif
#if ssh
  $ hg debugcapabilities ssh://user@dummy/orig | grep topics
    _exttopics_heads
    ext-topics-publish=none
    ext-topics-tns-heads
    topics
    topics-namespaces
#endif
#if http
  $ hg debugcapabilities http://localhost:$HGPORT/ | grep topics
    _exttopics_heads
    ext-topics-publish=none
    ext-topics-tns-heads
    topics
    topics-namespaces
#endif

#if local
  $ hg clone orig clone -q
#endif
#if ssh
  $ hg clone ssh://user@dummy/orig clone -q
#endif
#if http
  $ hg clone http://localhost:$HGPORT/ clone -q
#endif

  $ cd orig

changesets without topic namespace are freely exchanged

  $ echo apple > a
  $ hg debug-topic-namespace --clear
  $ hg topic apple
  marked working directory as topic: apple
  $ hg ci -qAm apple

  $ hg incoming -R ../clone
  comparing with * (glob)
  0: apple default//apple (draft)

  $ hg pull -R ../clone
  pulling from * (glob)

  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files
  new changesets bf4c1d971543 (1 drafts)
  (run 'hg update' to get a working copy)

changesets with topic namespaces are only exchanged if configuration allows

  $ echo banana > b
  $ hg debug-topic-namespace bob
  marked working directory as topic namespace: bob
  $ hg topic banana
  $ hg ci -qAm 'banana'

  $ hg incoming -R ../clone --config experimental.tns-default-pull-namespaces=foo
  comparing with * (glob)
  searching for changes
  no changes found
  [1]

  $ hg pull -R ../clone --config experimental.tns-default-pull-namespaces=foo
  pulling from * (glob)
  searching for changes
  no changes found

this config option takes a list of values

  $ hg incoming -R ../clone --config experimental.tns-default-pull-namespaces=foo,bob
  comparing with * (glob)
  searching for changes
  1: banana default//bob/banana (draft)

we have a "permit all" config value

  $ echo coconut > c
  $ hg debug-topic-namespace charlie
  $ hg topic coconut
  $ hg ci -qAm 'coconut'

  $ hg incoming -R ../clone --config experimental.tns-default-pull-namespaces=*
