annotate tests/test-copytrace-heuristics.t @ 42219:1afd9d1e55ca

tests: defines aliases for `hg log` calls in test-copytrace-heuristics.t

This also makes the test cases more consistent since a few had missed
the ":" in "changeset:" that the others used.

Test for the heuristic copytracing algorithm
============================================

  $ cat >> $TESTTMP/copytrace.sh << '__EOF__'
  > initclient() {
  > cat >> $1/.hg/hgrc <<EOF
  > [experimental]
  > copytrace = heuristics
  > copytrace.sourcecommitlimit = -1
  > EOF
  > }
  > __EOF__
  $ . "$TESTTMP/copytrace.sh"

  $ cat >> $HGRCPATH << EOF
  > [extensions]
  > rebase=
  > shelve=
  > [alias]
  > l = log -G -T 'changeset: {node}\n desc: {desc}\n'
  > pl = log -G -T 'changeset: {node}\n desc: {desc}, phase: {phase}\n'
  > EOF

NOTE: calling initclient() set copytrace.sourcecommitlimit=-1 as we want to
prevent the full copytrace algorithm to run and test the heuristic algorithm
without complexing the test cases with public and draft commits.

When the sourcecommitlimit is small and we have more drafts, we use heuristics only

  $ hg rebase -s 8b6e13696 -d .
  rebasing 1:8b6e13696c38 "added more things to a"
  file 'a' was deleted in local [dest] but was modified in other [source].
  What do you want to do?
  use (c)hanged version, leave (d)eleted, or leave (u)nresolved? u
  unresolved conflicts (see hg resolve, then hg rebase --continue)
  [1]

But when we have "sourcecommitlimit > (no. of drafts from base to c1)", we do
fullcopytracing

  $ hg rebase --abort
  rebase aborted
  $ hg rebase -s 8b6e13696 -d . --config experimental.copytrace.sourcecommitlimit=100
  rebasing 1:8b6e13696c38 "added more things to a"
  merging foo/bar and a to foo/bar
  saved backup bundle to $TESTTMP/repo/repo/repo/.hg/strip-backup/8b6e13696c38-fc14ac83-rebase.hg
