annotate tests/test-userguide.t @ 6805:e51dfd0e1a88 mercurial-6.0

test-compat: merge mercurial-6.1 into mercurial-6.0

ensure that all the scenarios in the user guide work as documented

basic repo
  $ hg init t
  $ cd t
  $ touch file1.c file2.c
  $ hg -q commit -A -m init

example 1: commit creates a changeset in draft phase
(this is nothing to do with evolve, but it's mentioned in the user guide)
  $ echo 'feature Y' >> file1.c
  $ hg commit -u alice -d '0 0' -m 'implement feature X'
  $ hg phase -r .
  1: draft
  $ hg identify -in
  6e725fd2be6f 1

example 2: unsafe amend with plain vanilla Mercurial: the original
commit is stripped
  $ hg commit --amend -u alice -d '1 0' -m 'implement feature Y'
  saved backup bundle to $TESTTMP/t/.hg/strip-backup/6e725fd2be6f-42cc74d4-amend.hg (glob)
  $ hg log -r 23fe4ac6d3f1
  abort: unknown revision '23fe4ac6d3f1'
  [10]
  $ hg identify -in
  fe0ecd3bd2a4 1

enable evolve for safe history modification
  $ cat >> $HGRCPATH <<EOF
  > [alias]
  > shortlog = log --template '{rev}:{node|short}  {phase}  {desc|firstline}\n'
  > [extensions]
  > rebase =
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

example 3: safe amend with "hg commit --amend" (figure 2)
  $ echo 'tweak feature Y' >> file1.c
  $ hg commit --amend -u alice -d '2 0' -m 'implement feature Y'
  $ hg shortlog -q -r fe0ecd3bd2a4
  abort: hidden revision 'fe0ecd3bd2a4' was rewritten as: 934359450037
  (use --hidden to access hidden revisions)

example 4: prune at head (figure 3)

  $ hg commit -m 'debug hack'
  $ hg prune .
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  working directory is now at 934359450037
  1 changesets pruned

  x  3:a3e0ef24aaf0  draft  debug hack

example 5: uncommit files at head (figure 4)
  $ echo 'relevant' >> file1.c
  $ echo 'irrelevant' >> file2.c
  $ hg commit -u dan -d '10 0' -m 'fix bug 234'
  $ hg uncommit file2.c

  $ hg commit -m 'step 1'
  $ echo step2 >> file1.c
  $ hg commit -m 'step 2'
  $ echo step3 >> file2.c
