depth: update depth to code to reuse ancestors depth Computing the depth of all N revs is no longer 'O(N**2)'

obsdiscovery: extract a smarted depth in utility The function is reusing previous depth for ancestors unless this is a merge.

obsdiscovery: simply some of the missing computation

discovery: implement some range based discovery This use the previously implemented methods to implement some discovery and fetch method using ranges. There is currently major performance issue and some aspect of the protocol will changes.

discovery: introduce a official 'obshash associated to a range The hash in a combination of the hash a its subrange. If the range is a leaf, we have the obsmarker relevant to the node in that leaf range.

discovery: introduce "stable slicing" methods We introduce new code that leverage the stable sorting to slices a graph in a way "stable" accross repository. This should allow us to use theses slices for obsolescence markers discovery.

discovery: adds a function doing revnum independant sorting The function is doing a topological sort without depending on revision number. This make the sort independent of the repository and suitable for discovery.

hgignore: also ignore the 'dist' directory This is generated by the 'sdist' command

obsexchange: drop unused module shame shame shame

MANIFEST.in: also includes topic That was also overlooked when we added topic.

MANIFEST.in: fix to include all evolve submodule This was overlooked before.

obsdiscovery: organize the code by category A private function get promoted to public since another module uses it.

evolution: drop the old __temporary__.advertiseobsolete option Mercurial code supports such feature directly though its 'experimental.evolution' config option. So we drop the old code and config.

README: mention the 'serveronly' extensions It is now properly installed with the package.

server only: test a more standard method of disabling exchange We have an "official" config option from core so lets just use it.

debian: don't delete evolve and topic extensions The debian packaging rules deletes all __init__.py to avoid conflicting with the __init__.py that declares the namespace package. Now that the evolve and topic extensions also live in __init__.py files, we clearly don't want to delete all __init__.py files anymore; only the hgext3rd/__init__.py should be deleted.

serveronly: replace exc.message with str(exc) BaseException.message is deprecated in Python 2.6, so use str() instead.

cleanup: stop using 'repo.join' methods These repository method might get deprecated soon. In addition, accessing the vfs-s is not that hard.

setup: add author_email The 'sdist' command complains about it otherwise.

readme: make it valid rst That will eventually please pypi

setup.py: remove unused and harmful code importing mercurial This was failing on some build system we have. The import seemed to succeed, but then mercurial.__all__ would fail. I don't know why, but since it's unused anyway, let's just drop it.

docs: update references to installation path

test: rename serveronly tests to reflect the new extension name

evolve: stop running 'serveronly' setup Since there is no common logic remaining the smaller extension we can stop running its setup in the main extensions

discovery: directly merge the 'obsdiscovery' exthelper in top level extensions There is no reason to proxy it through the 'obsexchange' submodule.

compat: drop advertising of unsupported experimental bundle2 part The support for this part was dropped long ago in 74bc8a0c2c02. But we forgot to remove it from the 'simple4server' extension.

exchange: dispatch all code in 'serveronly' to the appropriate submodule All code related to exchange is now in either 'evolve.obsexchange' or 'evolve.obsdiscovery', and the 'serveronly' extension is using their 'exthelper' to set itself up. As a side effect, the 'serveronly' extensions now enable better exchange when pushing from that server too.

capabilities: properly sort capabilities after updating them Capabilities are usually sorted. This is especially useful to avoid silly error in test.

pull: also issue warning for old mercurial version

exchange: split between modern and legacy code We make it clearer what code is old crust and what code is the cutting edge part.

push: add extra warning about pushing to old server Pushing using old method is slow and racy. We adds warning to point this to the user. We also add inline comment to clarify the function purpose.

push: exit obsexchange early if disabled We were exiting the function later, in particular -after- issuing a message about exchanging obsmarkers.

compat: drop special code handling change in push/pull op API All version of Mercurial we support have the same API.

discovery: split discovery related code in 'obsdiscovery' More code splitting for more clarity.

exchange: rename the module Let's add a 'obs' prefix to make the module role clearer.

setup.py: include all evolve submodule We are splitting more and more code into submodule, we make sure their are properly installed. As a side effect the 'legacy' module is now installed, that is not too important. The 'evolve.hack' package is still non installed by default, as intended.

evolve: switch away from deprecated repo.opener

serveronly: use the same extensions metadata than evolve This will avoid them to drift out of sync with evolve.

evolve: move extension metadata in their own module This will allow the server only extension to reuse them. As a side effect we can now simplify the config parsing in setup.py

evolve: specify the 'minimalhgversion' 3.7 added a new nice and shinny variable to help user know when they use the wrong version of Mercurial with an extension. We now use it.

serveronly: give the sub extension a way to access to the 'evolve' module We keep it as clean as possible but if the extension is specified with a direct path, we have to be a bit hacky. Being able to access the whole evolve extension from the 'serveronly' extension will lift multiple constraints on how we organise the code and will allow for cleaner and clearer code. We extract a minor function into a 'utility' module to have something to depends on.

test: update test to check for various way to import the serveronly things We add a "setup script" that update the PYTHONPATH to allow direct import of the extension code. Then we tests that all way to import the extensions works.

tests: move "test setup" script into a 'testlib' directory This will avoid cluttering the tests directory.

exchange: move code related to exchange into a 'evolve.exchange' submodule The evolve extension is HUGE, we split exchange code appart before doing more work on it.

exthelper: move command declaration into the exthelper This is necessary to allow sub module to declare commands too.

exthelper: add a 'merge' method This will help us spread more code in different sub module.

exthelper: extract into its own submodule That code is fairly independant, we extract it into its own extensions to clarify the code

makefile: add an 'install-home' target It is similar to the Mercurial one.

makefile: only check for HGROOT when running tests Otherwise we breaks other target that do not needs HGROOT.

tests: split pyflake and flake8 tests This allow more parallelism and better skip message

flake8: run on all python file We can now run it on all file in the repository to catch potential regression.

flake8: fix error in 'setup.py' Some strange indentation in there.

flake8: fix error in 'test2rst.py' There is variosu dead code in there :-/ but we just fix flake8 complains for now.

flake8: remove "error" in documentation configuration The "error" are debatable but cheap to fix.

flake8: enable on evolve too Now that all error are fixed we can run it on all file to prevent regression.

flake8: update the code sources to fixes a horde of pyflake warnings There is many of them, they all fixed.

flake8: register 'xrange' as a builtins For some reason, flake8 thinks is is undefined.

flake8: ignore an addition rules related to import Our initialization code is too complex to make flake8 happy

flake8: document all the exception we added

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.

destination: use the correct abort class for error These errors have been in Mercurial long enough. Having them will make the coming changesets simpler.

topic: list the number of head when --verbose is used Displaying more information in the topic list is useful, we continue with the number of heads on the topics, this will help highlight the problem to users. We only display head if there is more than one.

topic: list the number of troubled changesets when --verbose is used Displaying more information in the topic list is useful, we continue with the number of troubled changesets. This will help people to spot topics that needs evolution, for example after a pull.

topic: list the number of changesets when --verbose is used Displaying more information in the topic list is useful, we start with the most obvious: number of non-obsolete changeset in the topic.

topic: add color for the active topic We reuse the same color that the one used for the active bookmark.

topic: add formatter support Using formatter to output the list of topic will add support for color and richer templater. We add some test for output control. We introduce a dedicated test to help with coming more complexe output.

topic: extract the code listing all topics The code will become more complexe with formatter support and additional data in the verbose output. We extract the code in its own function first.

stack: introduce and explicite command to display the stack If is worth testing having the feature lives outside 'hg topic --list'. The 'stack' name is sub optimal because the conflict with 'status'. using "hg st" would still work as 'st' is hard coded, but this mean 'hg stack' has no short version.

testedwith: update to 3.9 This is might still 3.7 compatible but I'm no longer running the test and I would says the user base is small enough to not care.

topic: make sure we have the 'wlock' when setting topic We where writing the '.hg/topic' file without a lot. That was bad.

cleanup: removed unused mercurial.util import

compat: tolerate missing rebase extension

compat: mercurial dropped alias for hashlib.sha1

destination: add an XXX about handling destspace in destmerge This that we hopefully do not forget about this.

update: calculate 'partial' as core does

discovery: flake8

destination: flake8

style: update __init__.py

compat: adapt to the new destspace argument of destmerge The argument is currently ignored in the topic case for simplicity, but we properly accept it and propagate it to the original function to prevent crash and behavior regression in the non-topic case.

stack: prevent crash when topic is rooted on nullid We exclude null from displayed base. This was causing a crash when trying to display its description (we'll still have to handle the empty description case, but it is now less urgent).

test: add topic on the first 2 changesets too This will be used to add a test for topic rooted on nullid. We introduce this in its own changeset to reduce the noise if the actual changeset.

test: remove comment about new head warning The new head warning was buggy. This was fixed in bdc5bb223b50.

stack: also change the indexing of the t# reference Changeset 61f36480740f changed the index displayed (we now index from 1), but forgot to update the logic used to resolve the 't#' name. This changeset fixes it.

stack: change the ascii symbold for base Now that the children line go upward, '_' is no longer clear as is take the lower part of the line. We go for '^' that use the upper part.

stack: reverse the display order Most mercurial command display the most recent changeset first. We put `hg topic --list` inline with this.

topic: extract display from entry computation We are about to reverse the order of the output (most recent first) so it will be useful.

stack: start indexing at 't1' instead of 't0' I think 't0' could have special meaning (eg: before 't1', but still with topic activated) so let's keep room for that. Indexing from 1 is not crazy anyway.

commit: wrap "commitstatus" to take topic into account The "created new head" message was appearing for every single commit made on a topic. It should now properly only appears when a new head is actually created on a topic.

uisetup: add call to 'topicmap.modsetup' this was forgotten in 99c1a26abf3f. Tests did not broke because the wrapping of cg.apply only have performance impact (cache warmup).

uisetup: move all remaining wrapping into uisetup All our wrapping is now properly done at uisetup time. Hooray.

topicmap: move 'cgapply' wrapping into the topicmap module More gathering of related logic.

topicmap: move the 'usetopicmap' context manager into the topicmap module There is no good reason to not have it gathered with the rest.

patch: move setup of import/export logic into a function The function is now called during uisetup.

patch: remove version compatibility check We don't support anything under 3.7.

patch: document the section about import/export

patch: move import/export wrapping close to the function definition This gather similar logic together.

discovery: move all setup into a 'modsetup' function The various wrappings are moved into a function that live in the module and the function is now properly called during 'uisetup'.

revset: add a ui argument to 'modsetup' This is a gratuitous change for consistency with the function that use it.

revset: run 'modsetup' at uisetup time We are slowly moving away from module time wrapping. These thing should be done in the dedicated 'setup' method called by Mercurial.

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.

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
