destination: rename 'setupdest' to 'modsetup' the topic.revset module use 'modsetup' as a name for its setup function. It looks like a good name, lets unify names toward that.

destination: document 'setupdest' Let's make the role of this function clear.

destination: add a ui argument to 'setupdest' This is a gratuitous change for consistency.

destination: make sure 'setupdest' is the latest function in the module Let's introduce some consistency, end of module seems fine.

topicmap: move to new style import This unify with the new core Mercurial usage and this will make future changes to the imports easier to track.

stack: move to new style import This unify with the new core Mercurial usage and this will make future changes to the imports easier to track.

revset: move to new style import This unify with the new core Mercurial usage and this will make future changes to the imports easier to track.

discovery: move to new style import This unify with the new core Mercurial usage and this will make future changes to the imports easier to track.

destination: move to new style import This unify with the new core Mercurial usage and this will make future changes to the imports easier to track.

init: move to new style import This unify with the new core Mercurial usage and this will make future changes to the imports easier to track.

test: disable the new style rendering for "missing parent" The style kicks in when we display a partial tree. Supporting test running both 3.7 and default with this is painful, we disable the new feature for now.

tests: add pyflakes test

setup: make sure we use the imported module This prevent pyflakes to complains about it (and work around any possible demand import magic. I'm not sure why we do this important dance at all, but I'm leaving it there in doubt.

topicmap: whitespace

topiccache: directly instantiate a topiccache object when reading There is no need to rely on a temporary monkey patching.

readme: fix instruction to enable topic We moved the source code in 85390446f8c1 but we messed up the readme update. We are fixing it here.

stack: whitespace

stack: remove unused import

revset: add missing imports

revset: whitespace

discovery: whitespace

discovery: removed unused oldgetitem

setup: break long line

init: indent correctly

init: whitespace fixups

init: remove unused module

spelling: histedit

spelling: changeset

readme: remove the part about 3.7 and hgext3rd We are using direct path already so we don't need any magic here. The 'hgext3rd.'bit is only required (for 3.7) when the module is installed and we rely on sys.path to find it.

merge with other duplicate head

histedit: restrict default edited set to current topic when possible If we have an active topic, we restrict the edit within that topic.

stack: add a 'stack()' revset We give access to the list of relevant commit with a revset. Benefits over 'topic(.)' are the filtering of obsolete changeset and the reordering (to topological as-in unstability were resolved).

stack: display the base of the stack Displaying the first parent of the stack seems useful. I'm even tempted to call it 't0' and have the topic still active when 'hg up t0' is used to move to the base. As a side effect we gain a way to denote that the stack is not linear. I'm not super convinced that it is the right way to display it, but this is better than no information.

stack: add some default color configuration We can make the output more insightful with some default colors, let's do it.

stack: add basic formatter and label support This still is not great, especially I would like '-T' to be able to control how we display the changeset, but this is useful progress.

stack: show the currently active changeset and unstable ones Still super basic, but give a basic idea of the feature. We use both symbols and explicit text because symbols are cool but text is more explicit

stack: add "t" prefix to index in the output This make the existance and meaning of "t2" reference clearer.

stack: allow to refer to changeset using "t2" form hg up "t0" is seen as "update to the first changeset of my current topic". Eventually we'll drop the "t2" form in favor of the planned generic indexing operator '.{t2}'.

topic: don't take topic into account when pushing to non-topic repo Previously, pushing to a non-publishing repository without topic support would wrongfully use topic when searching for new heads.

destination: fix 'hg pull --rebase' I'm not sure why sometime functions do not have func_default but this is easy to fix. I've added a test to catch such stuffs it in the future.

packaging: fix setup.py and install as hgext3rd.topic This changeset is doing two things (gasp): - It fixes various errors in the setup.py - It move the topic source and install into hgext3rd.topic. This last part (code source move) use hgext3rd as namespace package to prevent installation nightmare. This won't be officially supported until Mercurial 3.8, but in the meantime, 3.7 user can enable it using the full package name: [extensions] hgext3rd.topic= Thanks goes to Julien Cristau <julien.cristau@logilab.fr> for the initial version of this.

destination: fix 'hg pull --rebase' I'm not sure why sometime functions does not have func_default but this is easy to fix. I've added a test to catch such stuff it in the future.

discovery: remove a spurious print

task: add index number to the output We are doing to use these number for easy movement in later changesets. The numbering will probably evolve over time but this is a good start.

stack: fix printing order in case of unstability The stack was displayed using revision number order, this give good result in the simple case (straight stack) but give bad result when the stack is not linear because of unstability. We fixes it by reusing the evolution logic for sorting. As we do not live next to evolution yet, we duplicated this logic for now.

stack: exclude obsolete changeset from the set We care about relevant changeset, obsolete have a new version somewhere and we don't care about the old one in our display. In case of unstability, the ordering used is still wrong.

stack: add a very first version of stack display with 'hg topic --list' This mark the first step toward a set of feature dedicated to displaying and moving within the current stack of work. Everything is still super basic so don't look too much at the feature. The goals of this changeset are: * having a flag to trigger the feature * having a basic (imperfect selection mechanism)

topic: get 'Abort' from error, not 'util' The class live in 'mercurial.error'.

Makefile: meant tests-@ not tests-tip

update: change default update destination to take topic in account When within a branch update to ngtip(branch). When within a topic update to the top topic.

rebase: test default rebase destination behavior In future mercurial 3.8, rebase and merge share the same destination logic. So if merge work, rebase should work as well. However, we double test it to be sure. Especially, in 3.7 the logic is not shared so we have to introduce an extra hack to share it in this case.

topicmap: write and read format from disc To prevent too awful performance we allow writing and reading topicmap cache. This is done with a lot of code duplication from core because core is not extensible enough.

topicmap: ensure that 'served' view is updated with topicmap There is multiple place that explicitly update the 'served' branchmap to ensure it stay up to date. We ensure it use the proper topicmap in this case.

topicmap: move the monkey patching into a context manager There is a couple of other place doing branchmap/topicmap update (of the served set), we'll have to set the monkey patching for them. This changeset is just doing the move to a context manager to make sure it is correct.

push: hackish handeling of new branch head from phase move The current head checking mechanism is not expecting "head change" from phase movement. Topic allows that, changeset with a topic moving to public can create a new head. We introduce a hack to double check that no head were added at the transaction level to work around this.

push: allow pushing new topic to non-publishing server by default This improves and fix the behavior change introduced by the new "topicmap". * Topics are properly ignored when pushing to a publishing server, * pushing new topics is allowed without --force a non-publishing server, * Pushing extra heads on a topic requires --force. Create of new head on a branch by phase movement is not properly detected for now. We'll improve that part in a later changesets. There is more awful monkey patching going on. We'll have to refactor core to get rid of them.

topic: take topic in account for all branch head computation This changeset introduce a "topicmap" that is tracking not just the head of all branches, but the heads of all branch+topic pair. Including the head of the part of the branch without any topic. In practice this means that BRANCHNAME now resolve to the tipmost part for the branch without topic and impact various other logic like head checking during push and default destination for update and merge (these aspect will need adjustment in later changesets). The on-the-fly-temporary-monkey-patching process is pretty horrible, but allow to move forward without waiting on having core patched. We use 'branch:topic' as the branchmap key, this is a small and easy hack that help use a lot for (future) support of heads discovery/checking and on disc cache. I'm not sure it is worthwhile to improve this until an implementation into core. Note that this changeset change the branchmap in all cases, including during exchange, see next changeset for improved behavior. We also currently have the on-disk cache disabled because the core branchmap is lacking phase information in its cache key. This will get done in a later changesets

testedwith: declare compatibility with Mercurial 3.7

Makefile: update all-version-tests to explicitly test 3.7

hgignore: also ignore testtimes

killdaemons: discard now that it's unused

test: drop custom run-tests.py We should use the one provided by Mercurial core directly.

Makefile: rework running of tests This makes running tests easier without depending on our own copy of run-tests.py (though I'd still prefer to keep that around.)

compat: adapt to change in mercurial core The code around merge destination have been changed in core, we do some basic adaptation to make sure we don't crash. Further rework to adapt//take advantage of core change would probably be useful but this is not the point of this commit.
