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.

topic: handle merge.update function signature change I think this is backwards compatible with how it used to be called, but I didn't worry about it too much either.

Merge.

test-topic-dest: test fixes I should have put in the previous change I split a bigger change from marmoute that included some rebase support that I wanted to discuss more, but I didn't correctly commit my fixes to the tests before pushing. Oops.

topic: fix changing topics of commits that have an amend_source Includes a test for this specific case, but we should probably spend more time squinting at the interactions between the current topic wrapper function and commitctx for memctx instances.

topic: remove useless call to c.parents()

topic: fix up change logic a little and add debug logging

merge: use topic to pick default destination If the topic have multiple heads, reduce that. Otherwise, pick the branch we are on.

topic: introduce a 'ngtip' concept The concept is to be massively used in naming and default destination logic. The name is horrible so that people find a better one.

template: test that topic is accessible through template This comes free with the namespace feature but it is good to have.

test: adapt to newer mercurial

patch: import topic from patch header If the used Mercurial supports it, we import topic from patch headers.

patch: add topic to exported patch If used Mercurial supports it, we add a topic header to patches.

topic: work around stringmatcher moving during development of hg 3.6

topic: allow use of topic(.) to match the p1 topic As far as I can tell this matches the behavior of branch(.) in core hg in tht it matches p1's value rather than the wdir value.

topic: fix missing error import

amend: allow clearing topics on amend

changectx: add topic method

topics: consistently use empty string instead of None This agrees with repo.currenttopic which uses ''. A subsequent patch is going to provide a context topic method that returns the empty string.

topics: drop debugging print in rebase

topics: allow commits that only change topic (issue4725) This allows amend to change topics. It also matches the behavior of branches.

topics: add listnames hook so completion works

rewrite: use a lock and transaction as spotted by devel warnings

topics: only apply topic to commits of the working copy

rebase: teach rebase how to copy topics

topic: wrap the underlying update function rather than the command This more properly manages the updates done by things like rebase.

commit: add a topic field to the in-editor commit text

topic: only require obsolete support for --change

commit: add a --topic flag

topic: note when switching topics

summary: add topic summary hook

topics: add command summary

docs: fix format of extension docstring

constants: extract key for extra into a constant It might be prudent to prefix it, and regardless it was bugging me to have it repeated everywhere.

topic: add ability to change topic of non-public changes This is a little crude, but it gets the job done. You probably don't want to use this without evolution for now.
