README: mention the addition of the topic extensions That is probably worth noting.

tests: run pyflake on all python files We have fixed the handfull of error pyflakes found on evolve so we can setup the test to prevent regression. Next stop flake8.

serveronly: fix undefined variable This is a legit bug caught by pyflake

legacy: properly test for mercurial version in the legacy extensions Otherwise 'demandimport' would delay the raising of ImportError.

evolve: prevent global variable shadowing Small and harmless pyflake complains.

evolve: drop some unused variables More pyflakes catches.

evolve: drop some unused import topic came with pyflake checking, let us make use of it.

README: fix evolve installation path We forgot to do so when we moved things to hgext3rd.

topic: merge the topic extension in the evolve repository There is a lot of synergy between the two concepts. Topic is expected to be able to smooth multiple of evolution sharp edge. Having them both in the same repository will make this collaboration easier.

test: adapt to new core output Troubles are now displayed by log so we have to update the test.

test: adapt to change in mercurial output Nothing major here.

compat: handle difference of signature for update destination hooks The 'check' argument have been dropped in 11c253997b0e. So we make it optional for compatibility.

setup.py: also install 'hgext3rd/__init__.py' This file is needed for the namespace package to work. (And also for the package to work on its own at all).

tutorial: add a very basic pointer in the readme Ideally we should at least build the html from the rst.

tutorial: add a second part about having multiple topic

tutorial: add a first version of the tutorial with the basics This is probably not wonderful but at least we have a base.

doc: add more details about the head checking Once again, probably not great, but better than nothing.

documentation: some basic update of the documentation So far the documentation was pretty scarce and a lot of important information was missing. The new content is probably not great but it is an improvement.

flake8: ignore N801 N801 is "class names should use CapWords convention" The message comes from a pep8 plugin "pep8-naming" which cares about naming conventions. If the plugin is installed, it is automatically used by pep8 and flake8.

flake8: don't ignore E713 now that it's fixed E713 is "test for membership should be ‘not in’"

flake8: fix E713 style

flake8: fix E301 style

flake8: fix E111 style OFF BY ONE ERRORS ARE THE WORST

flake8: fix E222 style

flake8: fix E127 style

flake8: fix W391 style

tests: add flake8 check This test will hopefully help prevent style errors. To be determined: which errors / warnings to ignore?

flake8: add file for rules to ignore This will help prevent users that have an editor with flake8 capabilities from fixing linter errors for rules that are not wanted by the project. Initially, this ignore list includes everything in the project that violates pep8. I'll try to ween this list down to something a little more manageable.

init: guard _namemap with repo.topics (issue5351) This prevents reading extra data on all repo commits when there is no topic for a given name. _namemap is called a lot, and it is often called for commit shas -- which should pretty much never be names of topics...

init: cache repo.topics

stack: add warning about multiple heads This seems a good spot to nudge people toward reducing there head count.

stack: add some behind information This is the next useful thing after branch

stack: add some basic branch information In the same spirit as knowing the topic you are on, having some branch data seem useful (yet, this smell a bit like summary)

stack: add some header with the topic name This is the first step of a move to add more data about a stack in the command output.

test: add testing of stack output in 'stack-data' test. We are going to display common information, so we reuse test case.

test: rename 'list' test to 'stack-data' We are about to add stack data information to 'hg stack'. As we'll re-use the test data creating the 'test-topic-list.t' we need to rename it first to embrace its new semantic.

stack: also dim bases Now that they may have index it seems better to have a stronger marking for bases.

stack: reusing the index number in base when applicable This clarify the branching when it is easy to track back the branching point. This does not takes the evolution graph into account yet.

stack: extra argument validation logic outside of showstack It seems sensible keep the 'showstack' function purely about actually displaying and existing stack.

summary: properly label the topic name in summary This should be labelled 'topic.active' so that color can pick it up properly.

topic: list the branches this topic belong to when verbose Using the verbose listing a bit more, this seems to be useful information.

topic: properly justify the verbose data when listing topic We align all data to the widest topic.

ngtip: rely on topicmap for 'ngtip' ngtip is an old function that predates the introduction of a more proper topic aware 'topicmap'. We replace the old code with a call to the new one. This change set function return type and have minor effect in a couple of place.

topic: list the number of 'behind' changeset when --verbose is used Displaying more information in the topic list is useful, we continue with the number of 'behind' changesets. This 'behind' count the number of new changesets on the default rebase destination. This will highlight topics that need rebasing.

destination: honor the sourceset argument of _destmerge Mercurial gained a "sourceset" argument to compute the merge destination of any changeset (the one in the 'sourceset'). This now works for the version in topic too. The support is quite basic (because we pick only one changeset from the sourceset) but that's a start.

destmerge: improve topic head computation and handling This rework get use two benefits: - heads are now computed on a "stabilized" state, - heads above the 'source' are now properly cleaned up,

evolve: extract the code copied from evolve in a submodule This will allow us to use that code in other module.

destmerge: honor the 'onheadcheck' argument This argument was introduced in Mercurial some time ago but the topic extension was never updated to take it in account. This is now fixed.
