automation: delete code related to Python 2.7 support

The building of Inno and WiX installers took a python_version argument
that allowed us to specify "2" or "3" for the major Python version. Since
we no longer support Python 2, we can delete this argument and everything
feeding into it.

shelve has a help message
  $ hg shelve -h
  hg shelve [OPTION]... [FILE]...
  
  save and set aside changes from the working directory
  
      Shelving takes files that "hg status" reports as not clean, saves the
      modifications to a bundle (a shelved change), and reverts the files so
      that their state in the working directory becomes clean.
  
      To restore these changes to the working directory, using "hg unshelve";
      this will work even if you switch to a different commit.
  
      When no files are specified, "hg shelve" saves all not-clean files. If
      specific files or directories are named, only changes to those files are
      shelved.
  
      In bare shelve (when no files are specified, without interactive, include
      and exclude option), shelving remembers information if the working
      directory was on newly created branch, in other words working directory
      was on different branch than its first parent. In this situation
      unshelving restores branch information to the working directory.
  
      Each shelved change has a name that makes it easier to find later. The
      name of a shelved change defaults to being based on the active bookmark,
      or if there is no active bookmark, the current named branch.  To specify a
      different name, use "--name".
  
      To see a list of existing shelved changes, use the "--list" option. For
      each shelved change, this will print its name, age, and description; use "
      --patch" or "--stat" for more details.
  
      To delete specific shelved changes, use "--delete". To delete all shelved
      changes, use "--cleanup".
  
  options ([+] can be repeated):
  
   -A --addremove           mark new/missing files as added/removed before
                            shelving
   -u --unknown             store unknown files in the shelve
      --cleanup             delete all shelved changes
      --date DATE           shelve with the specified commit date
   -d --delete              delete the named shelved change(s)
   -e --edit                invoke editor on commit messages
   -k --keep                shelve, but keep changes in the working directory
   -l --list                list current shelves
   -m --message TEXT        use text as shelve message
   -n --name NAME           use the given name for the shelved commit
   -p --patch               output patches for changes (provide the names of the
                            shelved changes as positional arguments)
   -i --interactive         interactive mode
      --stat                output diffstat-style summary of changes (provide
                            the names of the shelved changes as positional
                            arguments)
   -I --include PATTERN [+] include names matching the given patterns
   -X --exclude PATTERN [+] exclude names matching the given patterns
      --mq                  operate on patch repository
  
  (some details hidden, use --verbose to show complete help)

shelving in an empty repo should be possible
(this tests also that editor is not invoked, if '--edit' is not
specified)

  $ HGEDITOR=cat hg shelve
  shelved as default
  0 files updated, 0 files merged, 5 files removed, 0 files unresolved

  $ hg unshelve
  unshelving change 'default'

  $ hg commit -q -m 'initial commit'

  $ hg shelve
  nothing changed
  [1]

make sure shelve files were backed up

  $ ls .hg/shelve-backup
  default.hg
  default.patch
  default.shelve

checks to make sure we dont create a directory or
hidden file while choosing a new shelve name

when we are given a name

  $ hg shelve -n foo/bar
  abort: shelved change names can not contain slashes
  [255]
  $ hg shelve -n .baz
  abort: shelved change names can not start with '.'
  [255]
  $ hg shelve -n foo\\bar
  abort: shelved change names can not contain slashes
  [255]

when shelve has to choose itself

  $ hg branch x/y -q
  $ hg commit -q -m "Branch commit 0"
  $ hg shelve
  nothing changed
  [1]
  $ hg branch .x -q
  $ hg commit -q -m "Branch commit 1"
  $ hg shelve
  nothing changed
  [1]
  $ hg branch x\\y -q
  $ hg commit -q -m "Branch commit 2"
  $ hg shelve
  nothing changed
  [1]

cleaning the branches made for name checking tests

  $ hg up default -q
  $ hg strip e9177275307e+6a6d231f43d+882bae7c62c2 -q

create an mq patch - shelving should work fine with a patch applied

  $ echo n > n
  $ hg add n
  $ hg commit n -m second
  $ hg qnew second.patch

shelve a change that we will delete later

  $ echo a >> a/a
  $ hg shelve
  shelved as default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

set up some more complex changes to shelve

  $ echo a >> a/a
  $ hg mv b b.rename
  moving b/b to b.rename/b
  $ hg cp c c.copy
  $ hg mv d ghost
  $ rm ghost
  $ hg status -C
  M a/a
  A b.rename/b
    b/b
  A c.copy
    c
  R b/b
  R d
  ! ghost
    d

the common case - no options or filenames

  $ hg shelve
  shelved as default-01
  3 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg status -C

ensure that our shelved changes exist

  $ hg shelve -l
  default-01      (*)* changes to: [mq]: second.patch (glob)
  default         (*)* changes to: [mq]: second.patch (glob)

  $ hg shelve -l -p default

delete our older shelved change

  $ hg shelve -d default
  $ hg qfinish -a -q

ensure shelve backups aren't overwritten

  $ ls .hg/shelve-backup/
  default-1.hg
  default-1.patch
  default-1.shelve

  default.patch

local edits should not prevent a shelved change from applying

  $ printf "z\na\n" > a/a
  $ hg unshelve --keep
  unshelving change 'default-01'
  temporarily committing pending changes (restore with 'hg unshelve --abort')
  rebasing shelved changes
  merging a/a

  $ hg revert --all -q
  $ rm a/a.orig b.rename/b c.copy

apply it and make sure our state is as expected

(this also tests that same timestamp prevents backups from being
removed, even though there are more than 'maxbackups' backups)

  $ f -t .hg/shelve-backup/default.patch
  .hg/shelve-backup/default.patch: file
  $ touch -t 200001010000 .hg/shelve-backup/default.patch

  A c.copy
    c
  R b/b
  R d
  $ hg shelve -l

(both of default.hg and default-1.hg should be still kept, because it
is difficult to decide actual order of them from same timestamp)

  $ ls .hg/shelve-backup/

  [20]
  $ hg unshelve foo
  abort: shelved change 'foo' not found
  [10]

named shelves, specific filenames, and "commit messages" should all work
(this tests also that editor is invoked, if '--edit' is specified)

  $ hg status -C
  M a/a
  A b.rename/b
    b/b
  A c.copy
    c
  R b/b
  R d
  $ HGEDITOR=cat hg shelve -q -n wibble -m wat -e a
  wat
  
  
  HG: Enter commit message.  Lines beginning with 'HG:' are removed.
  HG: Leave message empty to abort commit.
  HG: --
  HG: user: shelve@localhost
  HG: branch 'default'
  HG: changed a/a

expect "a" to no longer be present, but status otherwise unchanged

  $ hg status -C
  A b.rename/b
    b/b
  A c.copy
    c
  R b/b
  R d
  $ hg shelve -l --stat
  wibble          (*)    wat (glob)
   a/a |  1 +
   1 files changed, 1 insertions(+), 0 deletions(-)

and now "a/a" should reappear

  $ cd a
  $ hg unshelve -q wibble
  $ cd ..
  $ hg status -C
  M a/a
  A b.rename/b
    b/b
  A c.copy
    c
  R b/b
  R d

ensure old shelve backups are being deleted automatically

  $ ls .hg/shelve-backup/
  default-01.hg
  default-01.patch
  default-01.shelve
  wibble.hg
  wibble.patch
  wibble.shelve

cause unshelving to result in a merge with 'a' conflicting

  $ hg shelve -q
  $ echo c>>a/a
  $ hg commit -m second
  $ hg tip --template '{files}\n'
  a/a

add an unrelated change that should be preserved

  $ mkdir foo
  $ echo foo > foo/foo
  $ hg add foo/foo

"hg unshelve" at REV5 implies steps below:

(1) commit changes in the working directory (REV6)
(2) unbundle shelved revision (REV7)
(3) rebase: merge REV7 into REV6 (REV6 => REV6, REV7)
(4) rebase: commit merged revision (REV8)
(5) rebase: update to REV6 (REV8 => REV6)
(6) update to REV5 (REV6 => REV5)
(7) abort transaction
