dirs: resolve fuzzer OOM situation by disallowing deep directory hierarchies

It seems like 2048 directories ought to be enough for any reasonable
use of Mercurial?

A previous version of this patch scanned for slashes before any allocations
occurred. That approach is slower than this in the happy path, but much faster
than this in the case that too many slashes are encountered. We may want to
revisit it in the future using memchr() so it'll be well-optimized by the libc
we're using.

.. bc:

    Mercurial will now defend against OOMs by refusing to operate on
    paths with 2048 or more components. This means that _extremely_
    deep path hierarchies will be rejected, but we anticipate nobody
    is using hierarchies this deep.

Test template map files and styles
==================================

  $ hg init a
  $ cd a
  $ echo a > a
  $ hg add a
  $ echo line 1 > b
  $ echo line 2 >> b
  $ hg commit -l b -d '1000000 0' -u 'User Name <user@hostname>'

  $ hg add b
  $ echo other 1 > c
  $ echo other 2 >> c
  $ echo >> c
  $ echo other 3 >> c
  $ hg commit -l c -d '1100000 0' -u 'A. N. Other <other@place>'

  $ hg add c
  $ hg commit -m 'no person' -d '1200000 0' -u 'other@place'
  $ echo c >> c
  $ hg commit -m 'no user, no domain' -d '1300000 0' -u 'person'

  $ echo foo > .hg/branch
  $ hg commit -m 'new branch' -d '1400000 0' -u 'person'

  $ hg co -q 3
  $ echo other 4 >> d
  $ hg add d
  $ hg commit -m 'new head' -d '1500000 0' -u 'person'

  $ hg merge -q foo
  $ hg commit -m 'merge' -d '1500001 0' -u 'person'

Second branch starting at nullrev:

  $ hg update null
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ echo second > second
  $ hg add second
  $ hg commit -m second -d '1000000 0' -u 'User Name <user@hostname>'
  created new head

  $ echo third > third
  $ hg add third
  $ hg mv second fourth
  $ hg commit -m third -d "2020-01-01 10:01"

Make sure user/global hgrc does not affect tests

  $ echo '[ui]' > .hg/hgrc
  $ echo 'logtemplate =' >> .hg/hgrc
  $ echo 'style =' >> .hg/hgrc

Add some simple styles to settings

  $ cat <<'EOF' >> .hg/hgrc
  > [templates]
  > simple = "{rev}\n"
  > simple2 = {rev}\n
  > rev = "should not precede {rev} keyword\n"
  > EOF

  $ hg log -l1 -Tsimple
  8
  $ hg log -l1 -Tsimple2
  8
  $ hg log -l1 -Trev
  should not precede 8 keyword
  $ hg log -l1 -T '{simple}'
  8

Map file shouldn't see user templates:

  $ cat <<EOF > tmpl
  > changeset = 'nothing expanded:{simple}\n'
  > EOF
  $ hg log -l1 --style ./tmpl
  nothing expanded:

Test templates and style maps in files:

  $ echo "{rev}" > tmpl
  $ hg log -l1 -T./tmpl
  8
  $ hg log -l1 -Tblah/blah
  blah/blah (no-eol)

  $ printf 'changeset = "{rev}\\n"\n' > map-simple
  $ hg log -l1 -T./map-simple
  8

 a map file may have [templates] and [templatealias] sections:

  $ cat <<'EOF' > map-simple
  > [templates]
  > changeset = "{a}\n"
  > [templatealias]
  > a = rev
  > EOF
  $ hg log -l1 -T./map-simple
  8

 so it can be included in hgrc

  $ cat <<EOF > myhgrc
  > %include $HGRCPATH
  > %include map-simple
  > [templates]
  > foo = "{changeset}"
  > EOF
  $ HGRCPATH=./myhgrc hg log -l1 -Tfoo
  8
  $ HGRCPATH=./myhgrc hg log -l1 -T'{a}\n'
  8

Test template map inheritance

  $ echo "__base__ = map-cmdline.default" > map-simple
  $ printf 'cset = "changeset: ***{rev}***\\n"\n' >> map-simple
  $ hg log -l1 -T./map-simple
  changeset: ***8***
  tag:         tip
  user:        test
  date:        Wed Jan 01 10:01:00 2020 +0000
  summary:     third
  

Test docheader, docfooter and separator in template map

  $ cat <<'EOF' > map-myjson
  > docheader = '\{\n'
  > docfooter = '\n}\n'
  > separator = ',\n'
  > changeset = ' {dict(rev, node|short)|json}'
  > EOF
  $ hg log -l2 -T./map-myjson
  {
   {"node": "95c24699272e", "rev": 8},
   {"node": "29114dbae42b", "rev": 7}
  }

Test docheader, docfooter and separator in [templates] section

  $ cat <<'EOF' >> .hg/hgrc
  > [templates]
  > myjson = ' {dict(rev, node|short)|json}'
  > myjson:docheader = '\{\n'
  > myjson:docfooter = '\n}\n'
  > myjson:separator = ',\n'
  > :docheader = 'should not be selected as a docheader for literal templates\n'
  > EOF
  $ hg log -l2 -Tmyjson
  {
   {"node": "95c24699272e", "rev": 8},
   {"node": "29114dbae42b", "rev": 7}
  }
  $ hg log -l1 -T'{rev}\n'
  8

Template should precede style option

  $ hg log -l1 --style default -T '{rev}\n'
  8

Add a commit with empty description, to ensure that the templates
below will omit the description line.

  $ echo c >> c
  $ hg add c
  $ hg commit -qm ' '

Default style is like normal output. Phases style should be the same
as default style, except for extra phase lines.

  $ hg log > log.out
  $ hg log --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out
  $ hg log -T phases > phases.out
  $ diff -U 0 log.out phases.out | egrep -v '^---|^\+\+\+|^@@'
  +phase:       draft
  +phase:       draft
  +phase:       draft
  +phase:       draft
  +phase:       draft
  +phase:       draft
  +phase:       draft
  +phase:       draft
  +phase:       draft
  +phase:       draft

  $ hg log -v > log.out
  $ hg log -v --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out
  $ hg log -v -T phases > phases.out
  $ diff -U 0 log.out phases.out | egrep -v '^---|^\+\+\+|^@@'
  +phase:       draft
  +phase:       draft
  +phase:       draft
  +phase:       draft
  +phase:       draft
  +phase:       draft
  +phase:       draft
  +phase:       draft
  +phase:       draft
  +phase:       draft

  $ hg log -q > log.out
  $ hg log -q --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out
  $ hg log -q -T phases > phases.out
  $ cmp log.out phases.out || diff -u log.out phases.out

  $ hg log --debug > log.out
  $ hg log --debug --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out
  $ hg log --debug -T phases > phases.out
  $ cmp log.out phases.out || diff -u log.out phases.out

Default style of working-directory revision should also be the same (but
date may change while running tests):

  $ hg log -r 'wdir()' | sed 's|^date:.*|date:|' > log.out
  $ hg log -r 'wdir()' --style default | sed 's|^date:.*|date:|' > style.out
  $ cmp log.out style.out || diff -u log.out style.out

  $ hg log -r 'wdir()' -v | sed 's|^date:.*|date:|' > log.out
  $ hg log -r 'wdir()' -v --style default | sed 's|^date:.*|date:|' > style.out
  $ cmp log.out style.out || diff -u log.out style.out

  $ hg log -r 'wdir()' -q > log.out
  $ hg log -r 'wdir()' -q --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out

  $ hg log -r 'wdir()' --debug | sed 's|^date:.*|date:|' > log.out
  $ hg log -r 'wdir()' --debug --style default \
  > | sed 's|^date:.*|date:|' > style.out
  $ cmp log.out style.out || diff -u log.out style.out

Default style should also preserve color information (issue2866):

  $ cp $HGRCPATH $HGRCPATH-bak
  $ cat <<EOF >> $HGRCPATH
  > [extensions]
  > color=
  > EOF

  $ hg --color=debug log > log.out
  $ hg --color=debug log --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out
  $ hg --color=debug log -T phases > phases.out
  $ diff -U 0 log.out phases.out | egrep -v '^---|^\+\+\+|^@@'
  +[log.phase|phase:       draft]

  $ hg --color=debug -v log > log.out
  $ hg --color=debug -v log --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out
  $ hg --color=debug -v log -T phases > phases.out

  $ hg --color=debug -q log > log.out
  $ hg --color=debug -q log --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out

  $ cmp log.out phases.out || diff -u log.out phases.out

  $ mv $HGRCPATH-bak $HGRCPATH

Remove commit with empty commit message, so as to not pollute further
tests.

  $ hg --config extensions.strip= strip -q .

Revision with no copies (used to print a traceback):

  $ hg tip -v --template '\n'
  

Compact style works:
