tests: add test about aborting content-divergence when multiple parents This patch adds tests for --abort flag of hg evolve command when we are resolving content-divergence which are on different parents and parent of one of them is the gca of both of them. The tests shows that we are doing good and we should advertise the flag during conflicts.

CHANGELOG: add an entry about the --update flag Since --update is still the default, we make the entry about --no-update.

evolve: show unfinished information in `hg status -v` (issue5886) `hg status -v` shows information about unfinished states or `hg status` shows it when `commands.status.verbose=True` is set. Before this patch, information about interrupted evolve does not show up because evolve does not resgiters in cmdutil.STATES. This patch make sure we register evolve related information there. There has been an idea to unify cmdutil.unfinishedstates and cmdutil.STATES which needs some work and the resulting state does looks a bit complicated. So till the time we unify them, let's fix this bug by registering in cmdutil.STATES.

style: drop a (commented) debug print Left-over from 4dcf87849f9d.

tests: update tests output with changes in d0abd7949ea3 in core hg CORE-TEST-OUTPUT-UPDATE: d0abd7949ea3 CORE-TEST-OUTPUT-UPDATE: 1e9c357d3ddf

branching: merge with stable Merging with the new 8.0.1 release.

Added tag 8.0.1 for changeset 0887c30255a1

packaging: prepare for 8.0.1 release

changelog: add a couple of missing entry

evolve: strip the extra obsmarkers if any on `hg evolve --abort` Previous patches started storing some obsmarkers which needs to stripped during `evolve --abort` which can't be stripped by stripping the new evolved changesets because they point to a node which existed before the evolution was performed. This patch adds logic to strip those obsmarkers by finding their indices in the obsstore and then stripping them.

evolve: store the obsmarkers to be deleted in evolvestate Sometimes, we don't create a new node and obsolete one of the old node in favour of an existing node. When user calls, `hg evolve --abort`, we need to strip that obsmarker to go back in the same old state. The obsmarker created for new node are stripped when the new nodes are stripped. This patch start storing such obsmarkers in the evolvestate so that we can delete them later if required. Right now we just store successsor and predecessor information, we might need a better obsmarker serialization techinque in future to make it more robust.

evolve: store obsmarkers to be deleted in evolvestate There are operations which don't create a new node rather they just obsolete one of the unstable node in favour of existing one. In such cases if a further resolution leads to conflicts and user calls `evolve --abort` or `evolve --stop`, we might need to delete that obsmarker. So let's store such obsmarkers in the evolvestate.

evolve: factor out logic to merge branches in separate function This patch moves the logic to merge branches while resolving content-divergence to a separate function. This makes code clear and better to understand.

tests: add more test of --stop while resolving content-divergence This tests the --stop flag when conflicts occur while relocating one of the divergent changesets.

evolve: strip the relocation commit on `hg evolve --stop` While resolving content-divergence on multiple parents, we relocate one of the commit on the parent of another one and then merge the divergent changesets. Merging can leads to conflicts, and if user does `hg evolve --stop`, we need to strip that relocated changeset too! This patch does that. Test changes demonstrates the fix.

evolve: declare updated and pctx variables in stopevolve() They will used in next patch.

evolve: store the old other divergent node after relocation in evolvestate When the content-divergent changes are on different parents and we relocate of the node to the parent of another one, we get a new other-divergent node. We still need to store the older other-divergent in evolvestate so that we can use that information.

evolve: factor out logic for --stop flag in separate function This will make code clean

tests: add test for --stop flag when resolving multiparents content-div This patch adds a test for --stop flag when we are in an interrupted content-divergent resolution which have multiple parents. Conflicts happen we merge the divergent changesets after relocation. The test shows that we need to strip the relocated changeset.

evolve: move logic to continue interrupted content-div resolution to new fn Each of the other type has defined their own function to continue/complete the interrupted resolution. We take out the logic for content-div resolution too in a separate function to make the top level function looks clean.

evolve: rename help topic evolve.interrupted-evolve to evolve.interrupted `evolve.interrupted-evolve` has the word evolve twice. Now that this help topic is a part of evolve command, evolve.interrupted will mean the interrupted evolve command only.

packaging: update tested-with statements in evolve and topic

CHANGELOG: mention about 4.6.1 compatibility

test-compat: merge mercurial-4.4 into mercurial-4.3

test-compat: merge mercurial-4.5 into mercurial-4.4

test-compat: merge stable into mercurial-4.5

utility: use ui.interactive() instead of checking config value Before this patch, the rev selection prompt which pops up in case of ambiguity to ask user to select a rev used to check the config value of ui.interactive which can is by default set to None. We should use ui.interactive() instead which is more smart in such cases. Thanks to martinvonz for suggesting this.

CHANGELOG: add couple of entries about things fixed We are preparing for a release!
