remotenames: synchronise remotenames after push also
Earlier we use to pull remotenames information from the server in case of pull
and clone only. This patch adds logic to push also command to pull remotenames
information.
This will help us in keeping the remotenames more upto date where there are a
lot people changing state of branches and bookmarks at the server.

Test template syntax and basic functionality
============================================
$ 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'
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'

Test division:
$ hg debugtemplate -r0 -v '{5 / 2} {mod(5, 2)}\n'
(template
(/
(integer '5')
(integer '2'))
(string ' ')
(func
(symbol 'mod')

(integer '5')
(integer '2')))
(string '\n'))
* keywords:
* functions: mod

$ hg debugtemplate -r0 -v '{5 / -2} {mod(5, -2)}\n'
(template

(integer '5')
(negate

$ hg debugtemplate -r0 -v '{-5 / -2} {mod(-5, -2)}\n'

Filters bind closer than arithmetic:
$ hg debugtemplate -r0 -v '{revset(".")|count - 1}\n'
(template
(-
(|
(func
(symbol 'revset')
(string '.'))
(symbol 'count'))
(integer '1'))
(string '\n'))
* keywords:
* functions: count, revset
0
But negate binds closer still:
$ hg debugtemplate -r0 -v '{1-3|stringify}\n'
(template
(-
(integer '1')
(|
(integer '3')
(symbol 'stringify')))
(string '\n'))
* keywords:
* functions: stringify
hg: parse error: arithmetic only defined on integers
[255]
$ hg debugtemplate -r0 -v '{-3|stringify}\n'
(template
(|
(negate
(integer '3'))
(symbol 'stringify'))
(string '\n'))
* keywords:
* functions: stringify
-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'))))
* keywords: desc, line
* functions: splitlines
line 1
line 2
Keyword arguments:
$ hg debugtemplate -r0 -v '{foo=bar|baz}'
(template
(keyvalue
(symbol 'foo')
(|
(symbol 'bar')
(symbol 'baz'))))
* keywords: bar, foo
* functions: baz
hg: parse error: can't use a key-value pair in this context

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

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 .

$ hg log -T '{file_copies % "{source} -> {name}\n"}' -r .

$ hg log -T '{rev} {ifcontains("fourth", file_copies, "t", "f")}\n' -r .:7

Internal resources shouldn't be exposed (issue5699):
$ hg log -r. -T '{cache}{ctx}{repo}{revcache}{templ}{ui}'
Never crash on internal resource not available:

Check that recursive reference does not fall into RuntimeError (issue4758):
common mistake:
$ cat << EOF > issue4758

abort: recursive reference 'changeset' in template
[255]
circular reference:
$ cat << EOF > issue4758

$ hg log --style ./issue4758
abort: recursive reference 'foo' in template
[255]

$ cat << EOF > issue4758

[255]
not a recursion if a keyword of the same name exists:

Test string escaping in nested expression:

Test quotes in nested expression are evaluated just like a $(command)
substitution in POSIX shells:
$ hg log -R a -r 8 -T '{"{"{rev}:{node|short}"}"}\n'
8:95c24699272e
$ hg log -R a -r 8 -T '{"{"\{{rev}} \"{node|short}\""}"}\n'
{8} "95c24699272e"
Test recursive evaluation:
$ hg init r
$ cd r
$ echo a > a
$ hg ci -Am '{rev}'
adding a
$ hg log -r 0 --template '{if(rev, desc)}\n'

$ hg branch -q 'text.{rev}'
$ echo aa >> aa
$ hg ci -u '{node|short}' -m 'desc to be wrapped desc to be wrapped'
$ hg log -l1 --template '{fill(desc, "20", author, branch)}'

Test bad template with better error message

Templater supports aliases of symbol and func() styles:
$ hg clone -q a aliases

Aliases should be applied only to command arguments and templates in hgrc.
Otherwise, our stock styles and web templates could be corrupted:
$ hg log -r0 -T '{rn} {utcdate(date)|isodate}\n'
0:1e4e1b8f71e0 1970-01-12 13:46 +0000
$ hg log -r0 --config ui.logtemplate='"{rn} {utcdate(date)|isodate}\n"'
0:1e4e1b8f71e0 1970-01-12 13:46 +0000
$ cat <<EOF > tmpl
> changeset = 'nothing expanded:{rn}\n'
> EOF
$ hg log -r0 --style ./tmpl
nothing expanded:
Aliases in formatter:
$ hg branches -T '{pad(branch, 7)} {rn}\n'
default 6:d41e714fe50d
foo 4:bbe44766e73d
Aliases should honor HGPLAIN:
$ HGPLAIN= hg log -r0 -T 'nothing expanded:{rn}\n'
nothing expanded:
$ HGPLAINEXCEPT=templatealias hg log -r0 -T '{rn}\n'
