Updating to a revision with a namespace should activate it

  $ hg up null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg debug-topic-namespace
  none
  $ hg topics
     feature (1 changesets)
  $ hg up 0
  switching to topic-namespace alice
  switching to topic feature
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg debug-topic-namespace
  alice
  $ hg topics
   * feature (1 changesets)

Updating to a topic namespace is not supported

  $ hg up alice
  abort: unknown revision 'alice'

Revsets

  $ nslog() {
  >   hg log -T '{rev}: {topic_namespace}\n' -r "$1"
  > }

  $ nslog 'topicnamespace()'

Parsing

  $ hg debugparsefqbn foo/bar//user26/feature -T '[{branch}] <{topic_namespace}> ({topic})\n'
  [foo/bar] <user26> (feature)

no double slashes means it's a named branch
  $ hg debug-parse-fqbn foo/bar
  branch:    foo/bar
  namespace: none
  topic:     

Formatting

  $ hg debugformatfqbn -b branch -n namespace -t topic
  branch//namespace/topic

  $ hg debug-format-fqbn -n namespace
  //namespace/

  $ hg debug-format-fqbn -b foo/bar -n user26 -t feature
  foo/bar//user26/feature

default values

  $ hg debug-format-fqbn -b default -n none -t '' --no-short
  default//none/
  $ hg debug-format-fqbn -b default -n none -t '' --short
  default

  $ hg debug-format-fqbn -b default -n namespace -t '' --no-short
  default//namespace/
  $ hg debug-format-fqbn -b default -n namespace -t '' --short
  default//namespace/

  $ hg debug-format-fqbn -b default -n none -t topic --no-short
  default//none/topic
  $ hg debug-format-fqbn -b default -n none -t topic --short
  default//topic
