evolve: remove unused struct import

compat: ask pytype to ignore some warnings It's expected to have a bunch of import and attribute errors in this module because it's for compatibility with different versions of hg and Python. Although it doesn't explain why a function wouldn't have __code__ attribute? So far I think it's a quirk of pytype.

evolve: extract logic of pre-checking divergence risk to its own function Extracting the logic (which is used to check if rewriting an obsolete revision will create divergence) to a function. This function will be used in upcoming patches of pre-checking. This is how we check if rewriting an obsolete revision will create divergence. We need to check two cases: If there is any 1) non-obsolete successor. -> easily done by `obsutil.successorssets()` 2) precursor with non-obsolete successor. -> using `evolvecmd.divergentsets()`

evolve: simplify some conditional extracted from a changeset of Sushil khanchi <sushilkhanchi97@gmail.com>

evolve: rename some variable ahead of time A refactoring of the content divergence resolution in on its way. use a distinctive name for some variable early to make the change easier to read later.

evolve: add logic to cover --stop when "divergent" relocation in play Changes in test file reflect the added behaviour. The intermediate changeset has been properly cleaned up by the `hg evolve --stop` call.

evolve: test to show that --stop is not working when "divergent" relocated Right now, --stop leave the intermediate changeset (relocating the divergent changeset to its new location behind). This this is an incomplete step it should be removed by `hg --stop`.

evolve: add test to show that --abort is working fine When resolving content-divergence where relocation of "divergent" changeset is also required, this test file make sure that --abort option is working fine.

evolve: fix a bug in logic to choose destination when no active topic

evolve: add test to demonstrate a bug when no active topic Added test shows that the logic to find the destination for `hg up` in the case when "working directory parent has a topic but wdir has no active topic" is buggy. This will be fixed in next patch.

evolve: fix a bug in logic of choosing destination for hg update

evolve: add test to demonstrate a bug when active topic is empty Added test shows that when current active topic is empty and we try to run `hg up`, it fails with an error. It's because this case is not correctly handled when we find a destination to update (when topics are in play) Next patch will fix this.

evolve: add more tests for --continue case when relocating "divergent"

evolve: use meaningful variable names for a return value

evolve: add logic to cover --continue case when relocating "divergent" Changes in test file demonstrate the added behaviour.

evolve: add test for `--continue` case when relocating "divergent" This test shows that for now we don't handle the continue case when relocating "divergent" cset hit merge conflict while resolving content-divergence. Next patch will be adding the support for --continue case.

evolve: use more specific key name to store in evolvestate Now, as we also relocate divergent cset if required, so let's use more specific key to track the relocation of "divergent" and "other".

evolve: move a test where it makes more sense

evolve: remove the unnecessary condition to check empty successors set I annotated the history of this "newer == [()]" condition and found that it was added in the initial stages of evolution project (more than 8 years ago) and there is no test where we get [()] as a successor set. So looks like "if not newer" is enough to check if it is empty. I also looked into obsutil.successorssets() implementation and I don't think it would give us [()] in any case.

evolve: delete redundant and incorrect code for updating dirstate In relocate() when we notice conflicts, we will try to fix up the dirstate by calling copies.duplicatecopies() and dirstatedance(). However, we had called _evolvemerge() just before that point and that has already fixed up the dirstate, so there's no need to do it again. Also, we did it incorrectly as the test case shows.

tests: demonstrate how evolve loses transitive copies when interrupted Let's say `b` has been renamed to `c` in commit A and then renamed to `d` in commit B. We now modify A in a way that will cause a conflict when we evolve B. `hg evolve` will now stop and let the user resolve the conflicts, but it will have lost the copy information in the working copy (should still be c->d).

evolve: use ui.configoverride() instead of ui.backupconfig() ui.configoverride() was added in hg 4.1. util.nullcontextmanager() was added in hg 4.4.

evolve: remove obsolete backup of allowemptycommit config We stopped setting the config in 88601e1cd5d8 (evolve: create new commit while resolving content-divergence, 2018-04-23), so there's no need to back it up.

evolve: remove dead initilization of "newnode" variable It's been dead since f9dad99a90d5 (evolve: create a new commit instead of amending one of the divergents, 2018-06-13).

py3: fix several TypeError formatting bytes with an exception object

evolve: preserve date when resolving content-divergence (issue6202) This patch changes the implementation to do a 3 way merge. In case of actual conflict, it take the newest date from both sides of the content-divergence.

test: add test for content divergence involving a date update In this case, each side update the date.

test: add test for content divergence involving a date update In this case, one side update to an earlier date.

test: add test for content divergence involving a date update In this case, one side update to an older date.

test: highlight data handling when solving divergence The current handling of date is lacking, we add test to highlight this.

evolve: add tests for the case when resolution parent is ambiguous

evolve: abort if deciding resolution parent is ambiguous While solving content-divergence, it could be hard to decide which cset should be treated as a resolution parent if there are multiple successors of divergent cset. i.e split case. But we are planning to make some update in handling this split case: 1) consider highest one if all splitted csets are in a single topological branch 2) still need to decide if 1) doesn't apply

evolve: make sure divergence resolution doesn't undo changes (issue6203) Before this patch, in content-divergence resolution logic if resolution parent is not the parent of any of the two divergent changesets then it could undo some changes introduced by previous revs (while resolving stack of content-divergent changesets) as demonstrated by the test added in previous patch. To solve this, what this patch doing is: if divergent cset has obsolete parent with a successor then first resolve the "orphan" instability of divergent cset by relocating, then perform the content-divergence resolution. After this change in logic, I found that it's kind of more correct as reflected by the changes in tests/test-evolve-content-divergent-corner-cases.t where it prevented creating conflicts while merging. Changes in tests/test-evolve-content-divergent-stack.t demonstrate the fixed behaviour. Next patches will be covering the `evolve --continue` case for the relocation of "divergent" cset.

evolve: add test to demonstrate issue6203 Current logic of content-divergence resolution contains a bug that if resolution parent is not the parent of any of the two divergent changesets, it could undo some changes. I think a good solution for this is to first relocate the divergent cset to it's obsolete parent's successor if applicable and then perform the content-divergence resolution. Next patch will fix the issue.

obslog: phase divergence fix for 5c41bb482867 I forgot to pull the latest version before publishing the topic :-(

obslog: phase divergence fix for b135591bec1a I forgot to pull the latest version before publishing the topic :-(

obslog: make {descdiff} not be indented and leave that to the template Same idea as the previous patch and same explanation for changes to the test case.

obslog: make {patch} not be indented and leave that to the template This removes some unwanted indentation from the tests. In the first case, it's because indent() doesn't indent a blank line. In the second case, it's because we used templating with {patch} and had not requested indentation (but we still got it before this patch). Note that tests will only pass with a very recent Mercurial (one with https://phab.mercurial-scm.org/D7432 applied).

obslog: make {succnodes} be full hex nodes It should be up to the user to shorten the nodeid as much or as little as they like.

obslog: remove now-unused code for plain styling We now always use a non-plain formatter for the non-local-filtering code paths, so we can remove the code for plain styling. I couldn't figure out how to replace the fm.formatlist() by something less about formatting, so I've only removed the irrelevant arguments from those calls.

obslog: redefine default output as a template, unless -f was given This was easier than I expected to do without affecting any test output at all. `hg obslog -f` is pretty broken with templating. For example, it inserts a single "date" field, but it provides two values for it if the dates are different. That results in a traceback when running e.g. `hg obslog -f -Tfoo` with non-local obsmarkers with different dates. We need to figure out what we want to put in the template for the filtered case. I've just left it out for now.

obslog: add newline after all markers in non-graphlog to match graphlog I'd also be fine with doing the reverse if that's preferred, but I really want them to be the same so they can use the same template.

obslog: make reason for unavailable patch part of template We need the reason to be in the template in order to be able to templatize the whole output.
