subrepo: drop the 'ui' parameter to archive()
The current state of subrepo methods is to pass a 'ui' object to some methods,
which has the effect of overriding the subrepo configuration since it is the
root repo's 'ui' that is passed along as deep as there are subrepos. Other
subrepo method are *not* passed the root 'ui', and instead delegate to their
repo object's 'ui'. Even in the former case where the root 'ui' is available,
some methods are inconsistent in their use of both the root 'ui' and the local
repo's 'ui'. (Consider hg._incoming() uses the root 'ui' for path expansion
and some status messages, but also calls bundlerepo.getremotechanges(), which
eventually calls discovery.findcommonincoming(), which calls
setdiscovery.findcommonheads(), which calls status() on the local repo 'ui'.)
This inconsistency with respect to the configured output level is probably
always hidden, because --verbose, --debug and --quiet, along with their 'ui.xxx'
equivalents in the global and user level hgrc files are propagated from the
parent repo to the subrepo via 'baseui'. The 'ui.xxx' settings in the parent
repo hgrc file are not propagated, but that seems like an unusual thing to set
on a per repo config file. Any 'ui.xxx' options changed by --config are also
not propagated, because they are set on repo.ui by dispatch.py, not repo.baseui.
The goal here is to cleanup the subrepo methods by dropping the 'ui' parameter,
which in turn prevents mixing subtly different 'ui' instances on a given subrepo
level. Some methods use more than just the output level settings in 'ui' (add
for example ends up calling scmutil.checkportabilityalert() with both the root
and local repo's 'ui' at different points). This series just goes for the low
hanging fruit and switches methods that only use the output level.
If we really care about not letting a subrepo config override the root repo's
output level, we can propagate the verbose, debug and quiet settings to the
subrepo in the same way 'ui.commitsubrepos' is in hgsubrepo.__init__.
Archive only uses the 'ui' object to call its progress() method, and gitsubrepo
calls status().

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 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 or leave (d)eleted? c rebasing 6:9455ee510502 "dev: merge default" saved backup bundle to $TESTTMP/ancestor-merge/.hg/strip-backup/1d1a643d390e-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 rebasing 2:ec2c14fb2984 "dev: f-dev stuff" rebasing 4:4b019212aaf6 "dev: merge default" remote changed f-default which local deleted use (c)hanged version or leave (d)eleted? c rebasing 6:9455ee510502 "dev: merge default" saved backup bundle to $TESTTMP/ancestor-merge-2/.hg/strip-backup/ec2c14fb2984-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 ..
