Tests for the admin::chainsaw-update command

setup

  $ cat >> $HGRCPATH << EOF

  $ hg init src

  $ cd src

  $ echo 1 > foo

  $ hg ci -Am1

  adding foo

  $ cd ..

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)

  $ 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
