topic: suggest to clear a topic that becomes empty We add a hint suggesting "hg topic --clear" when a topic becomes empty. This usually happens when all its changesets get public, that is when the user does a 'phase -p' or when they pull from a server. To discriminate relevant cases for which we should display the hint (and typically exclude explicit 'hg topic --clear' operation), we look for the transaction "type" to only consider 'phase' or 'push' transaction. In the latter case, the transaction name is not simply 'push-response' but it also included the remote URL so we need to match on string content.

topic: display a hint pointing at help when a topic becomes non-empty This is an attempt at avoiding "mistakes" by new users of topics when they pull a topic and publish its changesets while being checked out. In this case, the topic will become empty but still be active; however, if this is a "foreign" topic, the user will not likely want to keep it active for the next commit operation. So we add a hint message pointing at general help of "topics" command so that they can eventually do something and learn about "hg topics --clear".

content-div: add test showing `--stop` works during interrupted resolution This patch adds a test showing that the --stop flag of `hg evolve` works well during interrupted content-divergence resolution. The --stop flag now works with all the three different type of instability resolution very well and we should advertise it more.

evolve: create new commit while resolving content-divergence Before this patch, we used to amend one of the content-divergent changes with the changes from the merge. Creating a new commit will certain advantages like letting user enter a commit message, showing user the new merge diff before commiting the content-divergent resolution and give us more control in the implementation part. The reason amend was used initially was just because it was easy. There are some tests update due to change.

content-divergence: store the resolved revs in evolvestate['replacements'] The support for continuing a conflicted content-divergence resolution was added some time ago. That support lacked storing of the resolved rev in the evolvestate['replacements'] which marks the node as resolved and does not try to resolve that node again. Since we didn't store, the resolution, processes the same node again. This patch makes sure we store the information in evolvestate that a certain content-divergent node is resolved to prevent pre-processing it again.

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.

evolve: make `--abort` strip the temporary revs created during resolution During divergence resolution, `hg evolve` created temporary relocation commits which needs to be stripped off during `hg evolve --abort` to get back to the same state where we were. Previous patch added a new list temprevs to be stored in evolvestate. This patch starts storing the temp relocated node created during phase-divergence resolution in evolvestate and make sure we consider stripping it too while `hg evolve --abort`. The test changes demonstrate the fix. Now we are sucessfully aborting a phase-divergence resolution.

evolve: store a list of temprevs in evolvestate There are temporary revisions which are created as a part of divergence resolution which needs to be stripped off if user runs `hg evolve --abort`. We need to save the nodeids of those temporary revisions in the evolvestate. The temprevs list will help in the above mentioned use cases.

evolve: check for None before adding in set of revisions to strip After previous patch, replacements can contain None. Let's make sure we don't add None to the revisions to strip during `hg evolve --abort` The test changes demonstrate the usefulness of this and the previous patch. Now abort is working and public changesets are not a problem.

evolve: return the new replacement node to be stored in evolvestate While resolving phase-divergence, we can end up obsoleting the phase-divergent commit in favor of the public commit. Before this patch we return the node of public commit to store as a replacement of the phase-divergent commit. The above will not cause any problem till the time we use `hg evolve --abort` on an interrupted evolve which tries to strip the replacement nodes because it thinks that the replacements nodes are the ones which are created during the resolution and are new. Since we will be stripping a public node, `evolve --abort` will error out saying cannot strip public changeset, unable to abort evolve which is bad. We should make sure, replacements should only consist of new nodes formed. If the instablity is resolved by obsoleting in favour of old changeset, we should not store the old changeset in replacements in evolvestate.

evolve: don't make values of replacements dict lists There was inconsistency in code base related to the values stored in replacements dict in evolvestate. At some places we store a list, at some places we just store the nodeid. Let's make sure we store only the nodeid, not a list. If there are cases, when there are multiple replacements or changesets created during resolution, later patch will introduce storing temprevs in evolvestate which should be used.

tests: add a test file `--abort` flag while resolving phase-divergence This patch adds a new test file test-evolve-abort-phasediv.t which will contain tests for `hg evolve --abort` flag while resolving phase-divergence. There is a case in this test which does not work right which will be fixed in upcoming patches.

evolve: pass revisions as strings to commands.*() It's usually fine to pass integer revisions to e.g. commands.update(), but when directaccess is enabled, it attempts to parse it a revset, which fails.

tests: rename test-evolve-abort.t to test-evolve-abort-orphan.t We renamed the test file because it contains all the cases related to orphan resolution. Now we care about divergence resolution too and hence we must have separate specific test files for each type.

evolve: point to '--abort' in verbose status message f6979d64b9fb (evolve: point to '--abort' in error message, 2018-04-22) changed "hg update -C ." to "hg evolve --abort" in error messages. This commit makes the same change in the verbose status message (the one that warns about unfinished evolve). There's still one mention "hg update -C" in our codebase. That's after "hg evolve --content-divergent" fails, but I don't think "hg evolve --abort" works in that case (yet?).

evolvecmd: add comments and new lines in content-divergence handling logic I have visited this logic three times in last 10 days and I have to re-read the whole code to make sure I don't miss any part. Adding comments will help understanding the code in better and fast way.

evolve: show cset hash in "update to local conflict" message

evolve: use hg.updaterepo() instead of hg.update() to hide stats

evolve: fix the conflicts error message during content-divergence resolution Before last patch, we didn't had an automated way to continue an interrupted content-divergence resolution and we used to show a very long error message on how to continue manually. This patch replaces that long error message with nice small message which tells how to continue and how to abort. We still show `hg update -C .` to abort as we need to test and make `--abort` work in case of content-divergence.

evolve: add logic to continue interrupted content-divergence resolution We continue the interrupted content-divergence using the logic to complete content-divergence which we refactored in it's own function few patches ago. We had to delete evolvestate file before using cmdutil.amend() because otherwise we can't use the function. This leads to a hack which deletes the evolvestate file, we may want to not to use the high level API function here. Also we had to pass evolvestate also to _completecontentdivergent function because of this. This patch also, adds a test which demonstrates that the logic works fine.

evolve: store the evolvestate file when encountering conflicts This patch makes `hg evolve` store the evolvestate file when it encounters merge conflicts while resolving content-divergence.

evolve: take out logic to complete phase-divergence in separate fn This patch takes out the logic to complete the content-divergence resolution to it's own separate function so that we can reuse it in case of interrupted resolution.

evolve: store divergent nodes in evolvestate when resolving content-divergence We need to store the divergent nodes in evolvestate so that we can continue an interrupted phase divergence resolution.

branching: merge stable into default

tests: add test showing `hg evolve --stop` works fine with phase-divergence This patch adds a new test file which contains test demonstrating that `--stop` flag works well while resolving phase-divergence using `hg evolve`.

tests: rename the test file to add 'orphan' in the name test-evolve-stop.t contains test for `hg evolve --stop` for orphan resolution only. We also need to test the flag while resolving divergence. It will be good if we have a test file for each type of instability.

tests: test that `hg obslog wdir()` aborts with a useful message

obshistory: make obslog work when a commit doesn't have any description This logic is taken from logcmdutil.changesetprinter class. It checks that commit description is not empty before extracting the first line (before this patch it would try to index an empty list). Stripping description also makes obslog behave more like regular log when there are trailing/leading whitespaces.

obshistory: use a more appropriate type for obslog entries cand is actually a regular changeset and not 'M' (graphmod.MISSINGPARENT). And 'M' is only used for graph edges, but cand is drawn as a graph node. Visually there's no effect, but the code makes more sense this way.
