context: drop support for changeid of type long (API?)

I don't see a reason to support type long. It's pretty much the same
type as int. There was some discussion about it on the mailing list
around the time of ff2f90503d64 (context: work around `long` not
existing on Python 3, 2017-03-11), but I couldn't find a good reason
to keep it. There was some mention of hgtk doing "repo[long(rev)]",
but that was in 2012.

  $ 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

Test arithmetic operators have the right precedence:

  $ hg log -l 1 -T '{date(date, "%Y") + 5 * 10} {date(date, "%Y") - 2 * 3}\n'
  2020 1964
  $ hg log -l 1 -T '{date(date, "%Y") * 5 + 10} {date(date, "%Y") * 3 - 2}\n'
  9860 5908

Test division:

  $ hg debugtemplate -r0 -v '{5 / 2} {mod(5, 2)}\n'
  (template
    (/
      (integer '5')
      (integer '2'))
    (string ' ')
    (func
      (symbol 'mod')
      (list
        (integer '5')
        (integer '2')))
    (string '\n'))
  2 1
  $ hg debugtemplate -r0 -v '{5 / -2} {mod(5, -2)}\n'
  (template
    (/
      (integer '5')
      (negate
        (integer '2')))
    (string ' ')
    (func
      (symbol 'mod')
      (list
        (integer '5')
        (negate
          (integer '2'))))
    (string '\n'))
  -3 -1
  $ hg debugtemplate -r0 -v '{-5 / 2} {mod(-5, 2)}\n'
  (template
    (/
      (negate
        (integer '5'))
      (integer '2'))
    (string ' ')
    (func
      (symbol 'mod')
      (list
        (negate
          (integer '5'))
        (integer '2')))
    (string '\n'))
  -3 1
  $ hg debugtemplate -r0 -v '{-5 / -2} {mod(-5, -2)}\n'
  (template
    (/
      (negate
        (integer '5'))
      (negate
        (integer '2')))
    (string ' ')
    (func
      (symbol 'mod')
      (list
        (negate
          (integer '5'))
        (negate
          (integer '2'))))
    (string '\n'))
  2 -1

Filters bind closer than arithmetic:

  $ hg debugtemplate -r0 -v '{revset(".")|count - 1}\n'
  (template
    (-
      (|
        (func
          (symbol 'revset')
          (string '.'))
        (symbol 'count'))
      (integer '1'))
    (string '\n'))
  0

But negate binds closer still:

  $ hg debugtemplate -r0 -v '{1-3|stringify}\n'
  (template
    (-
      (integer '1')
      (|
        (integer '3')
        (symbol 'stringify')))
    (string '\n'))
  hg: parse error: arithmetic only defined on integers
  [255]
  $ hg debugtemplate -r0 -v '{-3|stringify}\n'
  (template
    (|
      (negate
        (integer '3'))
      (symbol 'stringify'))
    (string '\n'))
  -3

Filters bind as close as map operator:

  $ hg debugtemplate -r0 -v '{desc|splitlines % "{line}\n"}'
  (template
    (%
      (|
        (symbol 'desc')
        (symbol 'splitlines'))
      (template
        (symbol 'line')
        (string '\n'))))
  line 1
  line 2

Keyword arguments:

  $ hg debugtemplate -r0 -v '{foo=bar|baz}'
  (template
    (keyvalue
      (symbol 'foo')
      (|
        (symbol 'bar')
        (symbol 'baz'))))
  hg: parse error: can't use a key-value pair in this context
  [255]

  $ hg debugtemplate '{pad("foo", width=10, left=true)}\n'
         foo

Call function which takes named arguments by filter syntax:

  $ hg debugtemplate '{" "|separate}'
  $ hg debugtemplate '{("not", "an", "argument", "list")|separate}'
  hg: parse error: unknown method 'list'
  [255]

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"

  $ hg log --template '{join(file_copies, ",\n")}\n' -r .
  fourth (second)
  $ hg log -T '{file_copies % "{source} -> {name}\n"}' -r .
  second -> fourth
  $ hg log -T '{rev} {ifcontains("fourth", file_copies, "t", "f")}\n' -r .:7
  8 t
  7 f

Working-directory revision has special identifiers, though they are still
experimental:

  $ hg log -r 'wdir()' -T '{rev}:{node}\n'
  2147483647:ffffffffffffffffffffffffffffffffffffffff

Some keywords are invalid for working-directory revision, but they should
never cause crash:

  $ hg log -r 'wdir()' -T '{manifest}\n'
  

Internal resources shouldn't be exposed (issue5699):

  $ hg log -r. -T '{cache}{ctx}{repo}{revcache}{templ}{ui}'

Never crash on internal resource not available:

  $ hg --cwd .. debugtemplate '{"c0bebeef"|shortest}\n'
  abort: template resource not available: ctx
  [255]

  $ hg config -T '{author}'

Quoting for ui.logtemplate

  $ hg tip --config "ui.logtemplate={rev}\n"
  8
  $ hg tip --config "ui.logtemplate='{rev}\n'"
  8
  $ hg tip --config 'ui.logtemplate="{rev}\n"'
  8
  $ hg tip --config 'ui.logtemplate=n{rev}\n'
  n8

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 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 '^---|^\+\+\+|^@@'

  $ 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

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'

Error if no style:

Error if style missing key:

Error if style missing value:

Check that recursive reference does not fall into RuntimeError (issue4758):

 common mistake:

  $ cat << EOF > issue4758
  > changeset = '{changeset}\n'
  > EOF
  $ hg log --style ./issue4758
  abort: recursive reference 'changeset' in template
  [255]

 circular reference:

  $ cat << EOF > issue4758
  > changeset = '{foo}'
  > foo = '{changeset}'
  > EOF
  $ hg log --style ./issue4758
  abort: recursive reference 'foo' in template
  [255]

 buildmap() -> gettemplate(), where no thunk was made:

  $ cat << EOF > issue4758
  > changeset = '{files % changeset}\n'
  > EOF
  $ hg log --style ./issue4758
  abort: recursive reference 'changeset' in template
  [255]

 not a recursion if a keyword of the same name exists:

  $ cat << EOF > issue4758
  > changeset = '{tags % rev}'
  > rev = '{rev} {tag}\n'
  > EOF
  $ hg log --style ./issue4758 -r tip
  8 tip

Check that {phase} works correctly on parents:

  $ cat << EOF > parentphase
  > changeset_debug = '{rev} ({phase}):{parents}\n'
  > parent = ' {rev} ({phase})'
  > EOF
  $ hg phase -r 5 --public
  $ hg phase -r 7 --secret --force
  $ hg log --debug -G --style ./parentphase

  o  1 (public): 0 (public) -1 (public)

  o  0 (public): -1 (public) -1 (public)
  

Missing non-standard names give no error (backward compatibility):

  $ echo "changeset = '{c}'" > t
  $ hg log --style ./t

Defining non-standard name works:

  $ cat <<EOF > t
  > changeset = '{c}'
  > c = q
  > EOF
  $ hg log --style ./t

Formatnode filter works:

  $ hg -q log -r 0 --template '{node|formatnode}\n'
  1e4e1b8f71e0

  $ hg log -r 0 --template '{node|formatnode}\n'
  1e4e1b8f71e0

  1e4e1b8f71e05681d422154f5421e385fec3454f

Age filter:

  $ hg init unstable-hash
  $ cd unstable-hash
  $ hg log --template '{date|age}\n' > /dev/null || exit 1

  >>> from __future__ import absolute_import
  >>> import datetime
  >>> fp = open('a', 'wb')
  >>> n = datetime.datetime.now() + datetime.timedelta(366 * 7)
  >>> fp.write(b'%d-%d-%d 00:00' % (n.year, n.month, n.day)) and None
  >>> fp.close()
  $ hg add a
  $ hg commit -m future -d "`cat a`"

  $ hg log -l1 --template '{date|age}\n'
  7 years from now

  $ cd ..
  $ rm -rf unstable-hash

Filename filters:

  $ hg debugtemplate '{"foo/bar"|basename}|{"foo/"|basename}|{"foo"|basename}|\n'
  bar||foo|
  $ hg debugtemplate '{"foo/bar"|dirname}|{"foo/"|dirname}|{"foo"|dirname}|\n'
  foo|foo||
  $ hg debugtemplate '{"foo/bar"|stripdir}|{"foo/"|stripdir}|{"foo"|stripdir}|\n'
  foo|foo|foo|

Add a dummy commit to make up for the instability of the above:

  $ echo a > a
  $ hg add a
  $ hg ci -m future

Count filter:

  $ hg log -l1 --template '{node|count} {node|short|count}\n'
  40 12

  $ hg log -l1 --template '{revset("null^")|count} {revset(".")|count} {revset("0::3")|count}\n'

Upper/lower filters:

  $ hg log -r0 --template '{branch|upper}\n'
  DEFAULT
  $ hg log -r0 --template '{author|lower}\n'
  user name <user@hostname>
  $ hg log -r0 --template '{date|upper}\n'

  $ hg add b
  $ hg mv fourth fifth

Set up repository for non-ascii encoding tests:

  $ hg init nonascii
  $ cd nonascii
  $ $PYTHON <<EOF
  > open('latin1', 'wb').write(b'\xe9')
  > open('utf-8', 'wb').write(b'\xc3\xa9')
  > EOF
  $ HGENCODING=utf-8 hg branch -q `cat utf-8`
  $ HGENCODING=utf-8 hg ci -qAm "non-ascii branch: `cat utf-8`" utf-8

json filter should try round-trip conversion to utf-8:

  $ HGENCODING=ascii hg log -T "{branch|json}\n" -r0
  "\u00e9"
  $ HGENCODING=ascii hg log -T "{desc|json}\n" -r0
  "non-ascii branch: \u00e9"

json filter takes input as utf-8b:

  $ HGENCODING=ascii hg log -T "{'`cat utf-8`'|json}\n" -l1
  "\u00e9"
  $ HGENCODING=ascii hg log -T "{'`cat latin1`'|json}\n" -l1
  "\udce9"

utf8 filter:

  $ HGENCODING=ascii hg log -T "round-trip: {branch|utf8|hex}\n" -r0
  round-trip: c3a9
  $ HGENCODING=latin1 hg log -T "decoded: {'`cat latin1`'|utf8|hex}\n" -l1
  decoded: c3a9
  $ HGENCODING=ascii hg log -T "replaced: {'`cat latin1`'|utf8|hex}\n" -l1
  abort: decoding near * (glob)
  [255]
  $ hg log -T "invalid type: {rev|utf8}\n" -r0
  abort: template filter 'utf8' is not compatible with keyword 'rev'
  [255]

pad width:

  $ HGENCODING=utf-8 hg debugtemplate "{pad('`cat utf-8`', 2, '-')}\n"
  \xc3\xa9- (esc)

  $ cd ..

Test that template function in extension is registered as expected

  $ cd a

  $ cat <<EOF > $TESTTMP/customfunc.py

  > @templatefunc(b'custom()')
  > def custom(context, mapping, args):
  >     return b'custom'
  > EOF
  $ cat <<EOF > .hg/hgrc

  > customfunc = $TESTTMP/customfunc.py
  > EOF

  $ hg log -r . -T "{custom()}\n" --config customfunc.enabled=true

Test 'graphwidth' in 'hg log' on various topologies. The key here is that the
printed graphwidths 3, 5, 7, etc. should all line up in their respective
columns. We don't care about other aspects of the graph rendering here.

  $ hg init graphwidth
  $ cd graphwidth

  $ wrappabletext="a a a a a a a a a a a a"

  $ printf "first\n" > file
  $ hg add file
  $ hg commit -m "$wrappabletext"

  $ printf "first\nsecond\n" > file
  $ hg commit -m "$wrappabletext"

  $ hg checkout 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ printf "third\nfirst\n" > file
  $ hg commit -m "$wrappabletext"

  $ hg merge

The point of graphwidth is to allow wrapping that accounts for the space taken
by the graph.

  $ COLUMNS=10 hg log --graph -T "{fill(desc, termwidth - graphwidth)}"
  @  a a a a
  |  a a a a
  |  a a a a
  o    a a a
  |\   a a a
  | |  a a a
  | |  a a a
  | o  a a a
  | |  a a a
  | |  a a a
  | |  a a a
  o |    a a
  |\ \   a a
  | | |  a a
  | | |  a a
  | | |  a a
  | | |  a a
  | o |  a a
  | |/   a a

Something tricky happens when there are elided nodes; the next drawn row of
edges can be more than one column wider, but the graph width only increases by
one column. The remaining columns are added in between the nodes.

  $ hg log --graph -T "{graphwidth}" -r "0|2|4|5"
  o    5
  |\
  | \
  | :\
  o : :  7
  :/ /
  : o  5
  :/
  o  3
