perf: avoid using formatteropts for Mercurial earlier than 3.2
Before this patch, referring commands.formatteropts prevents perf.py
from being loaded by Mercurial earlier than 3.2 (or 7a7eed5176a4),
because it isn't available in such Mercurial, even though formatting
itself has been available since 2.2 (or ae5f92e154d3).
In addition to it, there are some code paths for Mercurial earlier
than 3.2. For example, setting "_prereadsize" attribute in perfindex()
and perfnodelookup() is effective only with hg earlier than 1.8 (or
61c9bc3da402).
This patch uses empty option list as formatteropts, if it isn't
available in commands module at runtime.
Disabling -T/--template option for earlier Mercurial should be
reasonable, because:
- since 427e80a18ef8, -T/--template for formatter has been available
- since 7a7eed5176a4, commands.formatteropts has been available
- the latter revision is direct child of the former

Test rebasing of merges with ancestors of the rebase destination - a situation that often happens when trying to recover from repeated merging with a mainline branch. The test case creates a dev branch that contains a couple of merges from the default branch. When rebasing to the default branch, these merges would be merges with ancestors on the same branch. The merges _could_ contain some interesting conflict resolutions or additional changes in the merge commit, but that is mixed up with the actual merge stuff and there is in general no way to separate them. Note: The dev branch contains _no_ changes to f-default. It might be unclear how rebasing of ancestor merges should be handled, but the current behavior with spurious prompts for conflicts in files that didn't change seems very wrong. $ hg init ancestor-merge $ cd ancestor-merge $ touch f-default $ hg ci -Aqm 'default: create f-default' $ hg branch -q dev $ hg ci -qm 'dev: create branch' $ echo stuff > f-dev $ hg ci -Aqm 'dev: f-dev stuff' $ hg up -q default $ echo stuff > f-default $ hg ci -m 'default: f-default stuff' $ hg up -q dev $ hg merge -q default $ hg ci -m 'dev: merge default' $ hg up -q default $ hg rm f-default $ hg ci -m 'default: remove f-default' $ hg up -q dev $ hg merge -q default $ hg ci -m 'dev: merge default' $ hg up -q default $ echo stuff > f-other $ hg ci -Aqm 'default: f-other stuff' $ hg tglog @ 7: 'default: f-other stuff' | | o 6: 'dev: merge default' dev |/| o | 5: 'default: remove f-default' | | | o 4: 'dev: merge default' dev |/| o | 3: 'default: f-default stuff' | | | o 2: 'dev: f-dev stuff' dev | | | o 1: 'dev: create branch' dev |/ o 0: 'default: create f-default' $ hg clone -qU . ../ancestor-merge-2 Full rebase all the way back from branching point: $ hg rebase -r 'only(dev,default)' -d default --config ui.interactive=True << EOF > c > EOF rebasing 1:1d1a643d390e "dev: create branch" note: rebase of 1:1d1a643d390e created no changes to commit rebasing 2:ec2c14fb2984 "dev: f-dev stuff" rebasing 4:4b019212aaf6 "dev: merge default" remote changed f-default which local deleted use (c)hanged version, leave (d)eleted, or leave (u)nresolved? c rebasing 6:9455ee510502 "dev: merge default" saved backup bundle to $TESTTMP/ancestor-merge/.hg/strip-backup/1d1a643d390e-43e9e04b-backup.hg (glob) $ hg tglog o 6: 'dev: merge default' | o 5: 'dev: merge default' | o 4: 'dev: f-dev stuff' | @ 3: 'default: f-other stuff' | o 2: 'default: remove f-default' | o 1: 'default: f-default stuff' | o 0: 'default: create f-default' Grafty cherry picking rebasing: $ cd ../ancestor-merge-2 $ hg phase -fdr0: $ hg rebase -r 'children(only(dev,default))' -d default --config ui.interactive=True << EOF > c > EOF rebasing 2:ec2c14fb2984 "dev: f-dev stuff" rebasing 4:4b019212aaf6 "dev: merge default" remote changed f-default which local deleted use (c)hanged version, leave (d)eleted, or leave (u)nresolved? c rebasing 6:9455ee510502 "dev: merge default" saved backup bundle to $TESTTMP/ancestor-merge-2/.hg/strip-backup/ec2c14fb2984-62d0b222-backup.hg (glob) $ hg tglog o 7: 'dev: merge default' | o 6: 'dev: merge default' | o 5: 'dev: f-dev stuff' | o 4: 'default: f-other stuff' | o 3: 'default: remove f-default' | o 2: 'default: f-default stuff' | | o 1: 'dev: create branch' dev |/ o 0: 'default: create f-default' $ cd ..
