rustfmt: format the codebase with nightly-2024-07-16

The CI has moved to a newer nightly, which slightly changes how it wraps
comments (which is the very option we use nightly for).

============================================
Tests for the admin::chainsaw-update command

Actual tests
============

Initial cloning if needed
-------------------------

  $ hg admin::chainsaw-update --dest repo --rev default --source ./src
  no such directory: "repo"
  creating repository at "repo"
  recovering after interrupted transaction, if any
  no interrupted transaction available
  pulling from ./src
  updating to revision 'default'
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  chainsaw-update to revision 'default' for repository at '$TESTTMP/repo' done

  $ cd repo

  $ cat foo

Test lock breacking capabilities
--------------------------------

Demonstrate lock-breaking capabilities with locks that regular Mercurial
operation would not break, because the hostnames registered in locks differ
from the current hostname (happens a lot with succesive containers):

  $ ln -s invalid.host.test/effffffc:171814 .hg/store/lock
  $ ln -s invalid.host.test/effffffc:171814 .hg/wlock
  $ hg debuglock
  lock:  (.*?), process 171814, host invalid.host.test/effffffc \((\d+)s\) (re)
  wlock: (.*?), process 171814, host invalid.host.test/effffffc \((\d+)s\) (re)
  [2]

  $ hg admin::chainsaw-update --no-purge-ignored --dest . --rev default --source ../src
  loaded repository at "."
  had to break store lock
  had to break working copy lock
  recovering after interrupted transaction, if any
  no interrupted transaction available
  pulling from ../src
  updating to revision 'default'
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  chainsaw-update to revision 'default' for repository at '$TESTTMP/repo' done

Test file purging capabilities
------------------------------

Let's also add local modifications (tracked and untracked) to demonstrate the
purging.

  $ echo untracked > bar
  $ echo modified > foo
  $ hg status -A
  M foo
  ? bar
  C root

  $ echo 2 > ../src/foo
  $ hg -R ../src commit -mB_1
  $ hg admin::chainsaw-update --dest . --rev default --source ../src -q
  no interrupted transaction available
  $ hg log -G

  $ hg status -A
  C foo
  C root
  $ cat foo
  2

Now behaviour with respect to ignored files: they are not purged if
the --no-purge-ignored flag is passed, but they are purged by default

  $ echo bar > .hgignore
  $ hg ci -Aqm hgignore
  $ echo ignored > bar
  $ hg status --all
  I bar
  C .hgignore
  C foo
  C root

  $ hg admin::chainsaw-update --no-purge-ignored --dest . --rev default --source ../src -q
  no interrupted transaction available
  $ hg status --all
  I bar
  C .hgignore
  C foo
  C root
  $ cat bar
  ignored

  $ hg admin::chainsaw-update --dest . --rev default --source ../src -q
  no interrupted transaction available
  $ hg status --all
  C .hgignore
  C foo
  C root
  $ test -f bar
  [1]

test --minimal-initial-cloning variant
--------------------------------------

With `--minimal-initial-cloning`, there is no "requesting all changes"
message. Hence clone bundles would be bypassed (TODO test both cases
# with an actual clone-bundle)

  $ cd ..
  $ hg admin::chainsaw-update --dest repo2 --rev default --source src --initial-clone-minimal
  no such directory: "repo2"
  creating repository at "repo2"
  recovering after interrupted transaction, if any
  no interrupted transaction available
  pulling from src
  updating to revision 'default'
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  chainsaw-update to revision 'default' for repository at '$TESTTMP/repo2' done

  $ cd repo2
  $ hg log -G
