+Tests for the admin::chainsaw-update command

+
+Actual tests
+============
+
+Simple invocation
+-----------------
+
+  $ hg init repo
+  $ cd repo
+  $ hg admin::chainsaw-update --rev default --source ../src
+  breaking locks, if any
+  recovering after interrupted transaction, if any
+  no interrupted transaction available
+  pulling from ../src
+  updating to revision 'default'
+  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
+  chainsaw-update to revision 'default' for repository at '$TESTTMP/repo' done
+
+  $ cat foo
+  1
+
+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 --rev default --source ../src -q
+  no interrupted transaction available
+
+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
+
+  $ echo 2 > ../src/foo
+  $ hg -R ../src commit -m2
+  $ hg admin::chainsaw-update --rev default --source ../src -q
+  no interrupted transaction available
+  $ hg status -A
+  C foo
+  $ 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
+
+  $ hg admin::chainsaw-update --no-purge-ignored --rev default --source ../src -q
+  no interrupted transaction available
+  $ hg status --all
+  I bar
+  C .hgignore
+  C foo
+  $ cat bar
+  ignored
+
+  $ hg admin::chainsaw-update --rev default --source ../src -q
+  no interrupted transaction available
+  $ hg status --all
+  C .hgignore
+  C foo
+  $ test -f bar
