revlog: move the details of revlog "v2" index inside revlog.utils.constants

the revlog module is quite large and this kind of format information would handy
for other module. So let us start to gather this information about the format in
a more appropriate place.

We update various reference to this information to use the new "source of truth"
in the process.

formatter output with paths:

  $ echo 'dupe:pushurl = https://example.com/dupe' >> .hg/hgrc
  $ hg paths -Tjson | sed 's|\\\\|\\|g'
  [
   {
    "name": "dupe",
    "pushurl": "https://example.com/dupe",
    "url": "$TESTTMP/b#tip"
   },
   {
    "name": "expand",
    "url": "$TESTTMP/a/$SOMETHING/bar"
   }
  ]
  $ hg paths -Tjson dupe | sed 's|\\\\|\\|g'
  [
   {
    "name": "dupe",
    "pushurl": "https://example.com/dupe",
    "url": "$TESTTMP/b#tip"
   }
  ]
  $ hg paths -Tjson -q unknown
  [
  ]
  [1]

log template:

 (behaves as a {name: path-string} dict by default)

  $ hg log -rnull -T '{peerurls}\n'
  dupe=$TESTTMP/b#tip expand=$TESTTMP/a/$SOMETHING/bar
  $ hg log -rnull -T '{join(peerurls, "\n")}\n'
  dupe=$TESTTMP/b#tip
  expand=$TESTTMP/a/$SOMETHING/bar
  $ hg log -rnull -T '{peerurls % "{name}: {url}\n"}'
  dupe: $TESTTMP/b#tip
  expand: $TESTTMP/a/$SOMETHING/bar
  $ hg log -rnull -T '{get(peerurls, "dupe")}\n'
  $TESTTMP/b#tip

 (sub options can be populated by map/dot operation)

  $ hg log -rnull \
  > -T '{get(peerurls, "dupe") % "url: {url}\npushurl: {pushurl}\n"}'
  url: $TESTTMP/b#tip
  pushurl: https://example.com/dupe
  $ hg log -rnull -T '{peerurls.dupe.pushurl}\n'
  https://example.com/dupe

 (in JSON, it's a dict of urls)

  $ hg log -rnull -T '{peerurls|json}\n' | sed 's|\\\\|/|g'
  {"dupe": "$TESTTMP/b#tip", "expand": "$TESTTMP/a/$SOMETHING/bar"}

password should be masked in plain output, but not in machine-readable/template
output:

  $ echo 'insecure = http://foo:[e-mail]/' >> .hg/hgrc
  $ hg paths insecure
  http://foo:***@example.com/
  $ hg paths -Tjson insecure
  [
   {
    "name": "insecure",
    "url": "http://foo:[e-mail]/"
   }
  ]
  $ hg log -rnull -T '{get(peerurls, "insecure")}\n'
  http://foo:[e-mail]/

zeroconf wraps ui.configitems(), which shouldn't crash at least:

  $ hg paths --config extensions.zeroconf=
  dupe = $TESTTMP/b#tip
  dupe:pushurl = https://example.com/dupe
  expand = $TESTTMP/a/$SOMETHING/bar
  insecure = http://foo:***@example.com/

  $ cd ..

sub-options for an undeclared path are ignored

  $ hg init suboptions
  $ cd suboptions

  $ cat > .hg/hgrc << EOF
  > [paths]
  > path0 = https://example.com/path0
  > path1:pushurl = https://example.com/path1
  > EOF
  $ hg paths
  path0 = https://example.com/path0

unknown sub-options aren't displayed

  $ cat > .hg/hgrc << EOF
  > [paths]
  > path0 = https://example.com/path0
  > path0:foo = https://example.com/path1
  > EOF

  $ hg paths
  path0 = https://example.com/path0

:pushurl must be a URL

  $ cat > .hg/hgrc << EOF
  > [paths]
  > default = /path/to/nothing
  > default:pushurl = /not/a/url
  > EOF

  $ hg paths
  (paths.default:pushurl not a URL; ignoring)
  default = /path/to/nothing

#fragment is not allowed in :pushurl

  $ cat > .hg/hgrc << EOF
  > [paths]
  > default = https://example.com/repo
  > invalid = https://example.com/repo
  > invalid:pushurl = https://example.com/repo#branch
  > EOF

  $ hg paths
  ("#fragment" in paths.invalid:pushurl not supported; ignoring)
  default = https://example.com/repo
  invalid = https://example.com/repo
  invalid:pushurl = https://example.com/repo

  $ cd ..

'file:' disables [paths] entries for clone destination

  $ cat >> $HGRCPATH <<EOF
  > [paths]
  > gpath1 = http://hg.example.com
  > EOF

  $ hg clone a gpath1
  abort: cannot create new http repository
  [255]

  $ hg clone a file:gpath1
  updating to branch default
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd gpath1
  $ hg -q id

  $ cd ..

Testing path referencing other paths
====================================

basic setup
-----------

  $ ls -1
  a
  b
  gpath1
  suboptions
  $ hg init chained_path
  $ cd chained_path
  $ cat << EOF > .hg/hgrc
  > [paths]
  > default=../a
  > other_default=path://default
  > path_with_branch=../branchy#foo
  > other_branch=path://path_with_branch
  > other_branched=path://path_with_branch#default
  > pushdest=../push-dest
  > pushdest:pushrev=default
  > pushdest2=path://pushdest
  > pushdest-overwrite=path://pushdest
  > pushdest-overwrite:pushrev=foo
  > EOF

  $ hg init ../branchy
  $ hg init ../push-dest
  $ hg debugbuilddag -R ../branchy '.:base+3<base@foo+5'
  $ hg log -G -T '{branch}\n' -R ../branchy
  o  foo

  o  foo

  |/
  o  default
  

  $ hg paths
  default = $TESTTMP/a
  gpath1 = http://hg.example.com/
  other_branch = $TESTTMP/branchy#foo
  other_branched = $TESTTMP/branchy#default
  other_default = $TESTTMP/a
  path_with_branch = $TESTTMP/branchy#foo
  pushdest = $TESTTMP/push-dest
  pushdest:pushrev = default
  pushdest-overwrite = $TESTTMP/push-dest
  pushdest-overwrite:pushrev = foo
  pushdest2 = $TESTTMP/push-dest
  pushdest2:pushrev = default

test basic chaining
-------------------

  $ hg path other_default
  $TESTTMP/a
  $ hg pull default
  pulling from $TESTTMP/a
  no changes found
  $ hg pull other_default
  pulling from $TESTTMP/a
  no changes found

test inheritance of the #fragment part
--------------------------------------

  $ hg pull path_with_branch
  pulling from $TESTTMP/branchy
  adding changesets
  adding manifests
  adding file changes
  added 6 changesets with 0 changes to 0 files
  new changesets 1ea73414a91b:bcebb50b77de
  (run 'hg update' to get a working copy)
  $ hg pull other_branch
  pulling from $TESTTMP/branchy
  no changes found
  $ hg pull other_branched
  pulling from $TESTTMP/branchy
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 3 changesets with 0 changes to 0 files (+1 heads)
  new changesets 66f7d451a68b:2dc09a01254d
  (run 'hg heads' to see heads)

test inheritance of the suboptions
----------------------------------

  $ hg push pushdest
  pushing to $TESTTMP/push-dest
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 4 changesets with 0 changes to 0 files
  $ hg push pushdest2
  pushing to $TESTTMP/push-dest
  searching for changes
  no changes found
  [1]
  $ hg push pushdest-overwrite --new-branch
  pushing to $TESTTMP/push-dest
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 5 changesets with 0 changes to 0 files (+1 heads)

Test chaining path:// definition
--------------------------------

This is currently unsupported, but feel free to implement the necessary
dependency detection.

  $ cat << EOF >> .hg/hgrc
  > chain_path=path://other_default
  > EOF

  $ hg id
  000000000000
  $ hg path
  abort: cannot use `path://other_default`, "other_default" is also define as a `path://`
  [255]
  $ hg pull chain_path
  abort: cannot use `path://other_default`, "other_default" is also define as a `path://`
  [255]

Doing an actual circle should always be an issue

  $ cat << EOF >> .hg/hgrc
  > rock=path://cissors
  > cissors=path://paper
  > paper=://rock
  > EOF

  $ hg id
  000000000000
  $ hg path
  abort: cannot use `path://other_default`, "other_default" is also define as a `path://`
  [255]
  $ hg pull chain_path
  abort: cannot use `path://other_default`, "other_default" is also define as a `path://`
  [255]

Test basic error cases
----------------------

  $ cat << EOF > .hg/hgrc
  > [paths]
  > error-missing=path://unknown
  > EOF
  $ hg path
  abort: cannot use `path://unknown`, "unknown" is not a known path
  [255]
  $ hg pull error-missing
  abort: cannot use `path://unknown`, "unknown" is not a known path
  [255]
