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

  $ hg log -G

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

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
