test-commandserver: change way of triggering early crash

Future patches will move the logging facility out of the server class, so
cmdserver.log can't be (ab)used for this purpose. Instead, let's hook the
factory function to raise exception.

hide outer repo
  $ hg init

Invalid syntax: no value

  $ cat > .hg/hgrc << EOF
  > novaluekey
  > EOF
  $ hg showconfig
  hg: parse error at $TESTTMP/.hg/hgrc:1: novaluekey
  [255]

Invalid syntax: no key

  $ cat > .hg/hgrc << EOF
  > =nokeyvalue
  > EOF
  $ hg showconfig
  hg: parse error at $TESTTMP/.hg/hgrc:1: =nokeyvalue
  [255]

Test hint about invalid syntax from leading white space

  $ cat > .hg/hgrc << EOF
  >  key=value
  > EOF
  $ hg showconfig
  hg: parse error at $TESTTMP/.hg/hgrc:1:  key=value
  unexpected leading whitespace
  [255]

  $ cat > .hg/hgrc << EOF
  >  [section]
  > key=value
  > EOF
  $ hg showconfig
  hg: parse error at $TESTTMP/.hg/hgrc:1:  [section]
  unexpected leading whitespace
  [255]

Reset hgrc

  $ echo > .hg/hgrc

Test case sensitive configuration

  $ cat <<EOF >> $HGRCPATH
  > [Section]
  > KeY = Case Sensitive
  > key = lower case
  > EOF

  $ hg showconfig Section
  Section.KeY=Case Sensitive
  Section.key=lower case

  $ hg showconfig Section -Tjson
  [
   {
    "name": "Section.KeY",
    "source": "*.hgrc:*", (glob)
    "value": "Case Sensitive"
   },
   {
    "name": "Section.key",
    "source": "*.hgrc:*", (glob)
    "value": "lower case"
   }
  ]
  $ hg showconfig Section.KeY -Tjson
  [
   {
    "name": "Section.KeY",
    "source": "*.hgrc:*", (glob)
    "value": "Case Sensitive"
   }
  ]
  $ hg showconfig -Tjson | tail -7
   },
   {
    "name": "*", (glob)
    "source": "*", (glob)
    "value": "*" (glob)
   }
  ]

Test empty config source:

  $ cat <<EOF > emptysource.py
  > def reposetup(ui, repo):
  >     ui.setconfig(b'empty', b'source', b'value')
  > EOF
  $ cp .hg/hgrc .hg/hgrc.orig
  $ cat <<EOF >> .hg/hgrc
  > [extensions]
  > emptysource = `pwd`/emptysource.py
  > EOF

  $ hg config --debug empty.source
  read config from: * (glob)
  none: value
  $ hg config empty.source -Tjson
  [
   {
    "name": "empty.source",
    "source": "",
    "value": "value"
   }
  ]

  $ cp .hg/hgrc.orig .hg/hgrc

Test "%unset"

  $ cat >> $HGRCPATH <<EOF
  > [unsettest]
  > local-hgrcpath = should be unset (HGRCPATH)
  > %unset local-hgrcpath
  > 
  > global = should be unset (HGRCPATH)
  > 
  > both = should be unset (HGRCPATH)
  > 
  > set-after-unset = should be unset (HGRCPATH)
  > EOF

  $ cat >> .hg/hgrc <<EOF
  > [unsettest]
  > local-hgrc = should be unset (.hg/hgrc)
  > %unset local-hgrc
  > 
  > %unset global
  > 
  > both = should be unset (.hg/hgrc)
  > %unset both
  > 
  > set-after-unset = should be unset (.hg/hgrc)
  > %unset set-after-unset
  > set-after-unset = should be set (.hg/hgrc)
  > EOF

  $ hg showconfig unsettest
  unsettest.set-after-unset=should be set (.hg/hgrc)

Test exit code when no config matches

  $ hg config Section.idontexist
  [1]

sub-options in [paths] aren't expanded

  $ cat > .hg/hgrc << EOF
  > [paths]
  > foo = ~/foo
  > foo:suboption = ~/foo
  > EOF

  $ hg showconfig paths
  paths.foo:suboption=~/foo
  paths.foo=$TESTTMP/foo

edit failure

  $ HGEDITOR=false hg config --edit
  abort: edit failed: false exited with status 1
  [255]

config affected by environment variables

  $ EDITOR=e1 VISUAL=e2 hg config --debug | grep 'ui\.editor'
  $VISUAL: ui.editor=e2

  $ VISUAL=e2 hg config --debug --config ui.editor=e3 | grep 'ui\.editor'
  --config: ui.editor=e3

  $ PAGER=p1 hg config --debug | grep 'pager\.pager'
  $PAGER: pager.pager=p1

  $ PAGER=p1 hg config --debug --config pager.pager=p2 | grep 'pager\.pager'
  --config: pager.pager=p2

verify that aliases are evaluated as well

  $ hg init aliastest
  $ cd aliastest
  $ cat > .hg/hgrc << EOF
  > [ui]
  > user = repo user
  > EOF
  $ touch index
  $ unset HGUSER
  $ hg ci -Am test
  adding index
  $ hg log --template '{author}\n'
  repo user
  $ cd ..

alias has lower priority

  $ hg init aliaspriority
  $ cd aliaspriority
  $ cat > .hg/hgrc << EOF
  > [ui]
  > user = alias user
  > username = repo user
  > EOF
  $ touch index
  $ unset HGUSER
  $ hg ci -Am test
  adding index
  $ hg log --template '{author}\n'
  repo user
  $ cd ..
