repo: properly progate "destroyed" call to super class The propagation of the 'destroyed' call was dropped. I'm not certain of the consequences of having a partially broken "destroyed" call, but this can't be good.

safeguard: add an option to disable automatic publishing Pushing to publishing server by mistake is a bit too common in the current state of evolve. Especially when the lack of good feature branch story make the use of -f a bit too common. So we add a very simple experimental option to allow warning (or abort) when changeset are pushed to a publishing server. This is unlikely to survive as is, but this is useful now.

readme: mention the fix for issue4354

checkheads: add a small debug message in case were we give up fast When node is unknown we assume it will stay. Yet, we might have markers to it that are going to be pushed. However, we do not have branch (ancestors) information unless we are very lucky an all of them are pruned. So for now we do not do anything assuming this will be rare. We still add a small debug message to help detecting such situation in the future.

checkheahds: switch algorithm to use pushed markers instead We now checks if markers involved in the push are relevant to nodes in the branch we try to replace. The approach is simpler and more robust. A test showing the limitation of the previous approach is added.

checkheads: add test where the rewrite of the other branch is not direct This will help testing that our logic is properly transitive.

check-heads: add tests about old heads indirectly pruned

checkheads: add more complexe case where a branch is split on multiple ones We extend case A-6 and A-7 with partial counterpart. These case are interesting because some of the partial pushing will (rightfully) works and some other won't.

checkheads: add a test of partially pushing a branch spread on multiple other If a branch is fully obsolete but is result are spread on multiple branch, pushing only one of them should detect we create new branches.

checkheads-tests: add missing parents recording for prune markers It is a bit too easy to forget about theses :/ If they are missing, the markers are not going to be exchanged on push.

checkheads: add some extra tests about "partial push" This adds a couple of test that checks that the head replacement code is properly ignored replacement not relevant to the push.

checkheads: handle partial obsolescence We now properly detects situations were only parts of the remote branch is obsoleted. To do so, we process children in the branch recursively to see if they will be obsolete. The current code has some trouble when the remote branch in unknown locally, or when the prune happened on a successors that is not relevant to the push. These case will be handled later. The processing code is becoming more and more complex, a lighter approach would be to check for the obsolescence markers that are relevant to the pushed set, but I prefer to stick with the current approach until more test cases are written.

test: force a push in inhibit's test Our checkheads detection code is becoming better and will prevent that push. As we do not care about this for inhibit, we simply force the push.

checkheads: basic handling of pruned heads (and associated tests) We now detect that heads was pruned and stop warning about it. Note that this has the same shortcoming as the existing code and only looks at the heads.

checkheads: give up on processing locally unknown changeset There are too many issue with locally unknown changesets, we ignore them for now while we get the core feature of the detection working.

checkheads: import our own copy of the checkheads code I expect enough change and experimental will be made that is it worthwhile having them done in evolution close to the rest of the exchange tests make sense.

compat: work around some filecache bug in 3.8 We are still compatible with this version.

obshashrange: have an half descent wireprotocol command The previous implementation was extremely hacky. The new version is based on the other discovery function and work!

obshashrange: improve message issued during discovery This is a minor new message that help to understand what is going on.

obshashrange: introduce basic sqlite caching Same as for stablerange, this is far from perfect but already a win. The cache is currently extremely volatile, but that will still be a win when doing multiple consecutive request during discovery. Better cache invalidation will happens "in the future".

stablerange: warm cache before using it server side We make sure the cache is fully up to date before starting to use it. Updating all value is more efficient and this give us a single point where we update and write on disk. Hopefully the cache have been kept up to date as we go anyway.

stablerange: warm cache before using it in findrangemissing We make sure the cache is fully up to date before starting to use it. Updating all value is more efficient and this give us a single point where we update and write on disk. Hopefully the cache have been kept up to date as we go anyway.

stablerange: warm cache on transaction (if obshashrange is enabled) If we plan to use it (obshashrange is enabled) we better keep it up to date. If a transaction adds node, we update the cache (this should also update the on disk version).

stablerange: introduce ondisk caching through sqlite There is many short cut and limitation with this first version of a cache but this allow use to envision some actual usage of the stablerange thingy so let us got for it.

stablerange: drop the cache on 'destroyed' if the repository have been strip, the cache is not usable as is. We could be smarter in the invalidation but that is a prototype anyway. G: changed hgext3rd/evolve/stablerange.py

stablerange: support loading the cache iteratively We record how far we loaded so that we can resume from this point.

stablerange: add some basic documentation about the cache

stablerange: warmup all upto a revision Let us start doing more systemic warming of the cache before we start writing things out. This prepare on disk caching.

debugstablerange: add a --verify flag to the command This should help us finding bugs.

stablerange: add a proper debugstablerange commands This commands allows to inspect the standard stable range of a range. That should come handy.

debugobshashrange: add a --subranges option We stop displaying -everything- by default, since is is usually very large. This will help getting better timing when measuring cache effect too, since we won't need to dig out deep cache value that real life usage would not touch.

debug: rename 'debugstablerange' to 'debugobshashrange' The command is more about the 'obshashrange' computation.

debugstablerange: improve output spacing On repo with a descent amount of changeset the number where overflowing in all directions. We give use more room now.

subranges: add a utility function to set the cache This is preparing on disk persistence for the value in this cache.

subranges: add a utility function to access the cache This is preparing on disk persistence for the value in this cache.

depth: add a utility function to set the cache This is preparing on disk persistence for the value in this cache.

depth: add a utility function to access the cache This is preparing on disk persistence for the value in this cache.

stablerange: add warming of the subrange Note that this means we build standard stable subrange for all changesets in the repository this is significantly more than what we were computing before and result is significantly more ranges being computed.

stablerange: fix merge slicing when range has multiple roots The first element in the bottom set is not necessarly the one with the lowest revision. We now properly compute and use the minimum value.

stablerange: small style fix

merge-slicing: introduce and use "inheritance point" for merge The first part of the stable sorted list of revision of a merge will shared with the one of others. This means we can reuse subranges computed from that point to compute some of the subranges from the merge. That point is latest point in the stable sorted list where the depth of the revisions match its index (that means all revision earlier in the stable sorted list are its ancestors, no dangling unrelated branches exists). This is a bit expensive to find since we have to walk all the revision, but being able to reuse subranges in all case (not just regular changesets) provide a massive speedup so the cost is worth it.

stablerange: rearrange the code picking subrange to warm Same logic, as the previous changesets, we prepare the code before adding merge support.

stablerange: rearrange the reusing logic to prepare to merge We'll soon be able to reuse some lower range when dealing with merge too. So we prepare the code for this in advance for clarity.

merge-slicing: explain an alternative implementation in a comments It has a better time complexity so a C implementation would likely out perform the current implementation

merge-slicing: use reachable roots to filter the various branches Reachable roots does what we want and have a quite fast C implementation.

merge-slicing: simplify various aspect of the code Especially the case were the bottom have single heads is not more efficiently handled.

stablerange: soon it will not provide any benefit and it gets in the way This was a bit strange and memory consuming anyway.

revsfromrange: reuse information from the stablesort We collaborate with the stablesort to store the order that led to a merge. That way, when we needs to retrieve revision from that merge we can reuse that order. We might need to filter to only retains ancestors of the merge we care about but skipping the stablesort safe a large amount of time.

stablesort: allow a callback to be triggered on merge Storing some information as we sort is going to be useful to avoid performing multiple sort while computing the stablerange.

minor simplification around rangelength

more explicite name in revsfromrange

stablerange: cache parents We happens to be doing and awful amount of parent call. We cache them locally for efficiency.

merge-slicing: avoid doing the same work twice We have already computed the list of revision in that bottom slice as 'hrevs' so we do not need to compute it a second time.

stablerange: fix a bug when a top slice ended on a merge Our "smart" detection of merge was buggy if the top slice ended on a merge. This is not fixed and tested.

slicesrangeat: stop double setting the revsinranges cache The cache should have already been filled by the logic warming the cache for the parent.

subranges: remove the recursivity of the call to isubranges(parentrange) We add some logic to ensure we'll have hot cache for the parent ranges when that matters, the cache is filled from ancestors to descendant to ensure this. The range are still 'created from descendant to ancestors to fill the revsfromrange cache since it important.

subranges: detach cache logic from computation logic Having both the logic around cache checking and setting makes is a bit harder to follow. In addition, this allow to gather the computation logic next to the other related function.

findmissingrange: properly queue new subrange for slicing The previous code was buggy and used the wrong variable leading to no extra slicing being performed to file the sample at the requested size.

findmissingrange: fix reversed value in debug output "oops"

stablecache: warmup on unfiltered repository We only looks at ancestors revision so filtering will not have any effect. This reduce overhead from the filtering.

stablerange: rename the class This is much more than just a cache now.

stablerange: do not inherit from dict This seems like and old cargo cult that when unnoticed.

stablerange: move a utility function around It make more sense to have this small function earlier in the series

stablerange: remove the now unused individual range class That class is now longer necessary, we dropped its usage for performance reason.

stablerange: directly use tuple to refer to a stable range Now that all advance logic lives in the unified class we no longer needs the individual class. Creating and operating on this cache introduce a significant overhead that we can not stop having. From now on, a range a is pair tuple '(headrev, index)'. Long live the tuple.

obshash: properly cache obshash value The code was buggy and only cached non-nullid/non-inherited value. This was previous hidden because we were using a 'propertycache' to cache the value on the range object. This fixes it and restore a lot of performance.

stablerange: directly use 'self' when possible Code movement introduced multiple silly case were we where accessing 'self' though 'repo.stablerange' for no good reasons.

revsfromrange: set the cache for the multiple bottom ranges in merge slicing We no longer rely on the object magic here.

revsfromrange: set the cache for the single bottom range in merge slicing We no longer rely on the object magic here.

revsfromrange: set the cache for the top range in merge slicing We no longer rely on the object magic here.

revsfromrange: remove reference to '_revs' in merge slicing Given '_revs' is a property from the cache, we use the official method of the object we are on instead. That method should be using the same cache than the property if available.

revsfromcache: update cache for the top slice if possible Same logic, we update the cache if have the data.

revsfromrange: skip setting the cache for length-1 top entry The content of the range is trivial to compute.

revsfromrange: update cache for parentrange directly in the code We update it where it matters if we detect that we have the data.

revsfromramge: hard code the single changeset range case That case is trivial and triggering and full stable sort for it seems a bit silly.

stablerange: introduce caching for the full revision in a set Such cache proved handy in the "per-range" class so we carry it along to the unified class. cf documentation for details.

stablerange: add a cache for stablesort ordering This will be very handy for merge, cf inline documentation for details.

stablerange: move revs computation within the main class We still need to compute the revision withing a range when we slice a merge. This is the last large logic that remains in the individual class and we migrate is on the main class.

stablerange: minor method reorders on the main class We put the public method first for clarify.

stablerange: drop "key" and "id" logic form the class We can restrict to the bare minimun for equality and hashing now.

stablerange: drop length from the class There is not remaining user.

stablerange: drop _depth Nothing uses it anymore.

stablerange: drop __repr__ IT was used for debug and the class is on it way out.

stablerange: drop the subranges method on the small class Nobody use it anymore.

stablerange: use subranges from the main class in subrangesclosure This is the last method used on the class.

stablerange: use subranges from the main class in _obshashrange This is the last method used on the class.

stablerange: use subranges from the main class in findrangemissing This is the last method used on the class.

stablerange: make sure nobody use '.depth' anymore

stablerange: use depthrevs in range slicing We stop using the property from the class to get us closer to tuple.

stablerange: use depthrevs in debugstablerange We stop using the property from the class to get us closer to tuple.

stablerange: use rangelength inside the class itself We stop using the building '__len__' this get use closer to be able to use a tuple.

stablerange: use rangelength in '_slicesatrange' We stop using the building '__len__' this get use closer to be able to use a tuple.

stablerange: use rangelength in '_slicepoint' We stop using the building '__len__' this get use closer to be able to use a tuple.

stablerange: use rangelength in subrangesclosure We stop using the building '__len__' this get use closer to be able to use a tuple.

stablerange: use rangelength in _obshashrange We stop using the building '__len__' this get use closer to be able to use a tuple.

stablerange: use rangelength in debugstablerange We stop using the building '__len__' this get use closer to be able to use a tuple.

stablerange: use rangelength in findmissingrange We stop using the building '__len__' this get use closer to be able to use a tuple.

stablerange: make sure nobody use '.index' anymore We rename the attribute for good measure.

stablerange: stop using '.index' inside the class itself We now access '[1]' as we'll do with the future tuple.

stablerange: stop using '.index' in '_slicesrangeat' We now access '[1]' as we'll do with the future tuple.

stablerange: stop using '.index' in '_slicepoint' We now access '[1]' as we'll do with the future tuple.

stablerange: stop using '.index' in 'rangelength' We now access '[1]' as we'll do with the future tuple.

stablerange: stop using '.index' in '_queryrange' We now access '[1]' as we'll do with the future tuple.

stablerange: stop using '.index' in debugstablerange We now access '[1]' as we'll do with the future tuple.

stablerange: make sure nobody use the 'stablekey' property outside the class

stablerange: make sure nobody use '.head' anymore We rename the attribute for good measure.

stablerange: stop using '.head' inside the class We now access '[0]' as we'll do with the future tuple.

stablerange: stop using '.head' in '_slicesrangeat' We now access '[0]' as we'll do with the future tuple.

stablerange: stop using '.head' in '_slicepoint' We now access '[0]' as we'll do with the future tuple.

stablerange: stop using '.head' in rangelength We now access '[0]' as we'll do with the future tuple.

stablerange: stop using '.head' in debugstablerange We now access '[0]' as we'll do with the future tuple.

stablerange: remove node unused 'node' property Close to killing that object.

stablerange: stop using '.node' in __repr__ This remove the last user to this method.

stablerange: change the key to use the revision number Using node is more stable but for now do not have on disk caching and revision number should be find in memory. This makes the data used for the file cache closer to what it will be when we use tuple. We might reintroduce node in the future but let us keep it simple for now.

stablerange: stop using '.node' in _queryrange We access the range-head revision number by index and convert it on site.

stablerange: stop using '.node' in debugstablerange We access the range-head revision number by index and convert it on site.

stablerange: stop using '.node' in findmissingrange We access the range-head revision number by index and convert it on site.

stablerange: stop using '.node' in obshashrange We access the range-head revision number by index and convert it on site.

stablerange: stop using '.node' in subrangesclosure We access the range-head revision number by index and convert it on site.

stablerange: have the class behave as a tuple If we want people to use a tuple, we should offer them a tuple. This should help update most of the code iteratively.

obshashrange: extract computation back into the discovery module This obshash is related to discovery and it seems more appropriate to have to live there. This remove the last large piece of logic from the class. We'll now be able to slowly turn it into a tuple.

obshashrange: use a small utility function to access the obshash If we want the object to disappear we needs the top level code to stop accessing its attribute.

debugstablerange: minor code reformat The content of that list will become more complex as we drop the object so we make sure to have one value per line for clarity.

stablerange: move the subrangesclosure inside the module This seems more suitable and open the way to simple update of how we build things without too much impact outside the module. The debug command is still in the 'obsdiscovery' module because it also deal to obshash and I'm not sure of were this should live yet.

stablerange: compute subranges from parent when possible Unless we are a merge, we can infer the standard subranges of a range by reusing the subranger of its parent. We update the implementation to do so. We still needs the "old way" for merge. We move that code in a dedicated function for the sake of simplicity.

stablerange: add an official warmup function The function is responsible for making sure we have the necessary data for a sets of heads. For now this only warm the depth cache. More will follow soon. Such explicite warmup will be usefull for on disck caching as an early point of writing will be easier.

stablerange: remove now unnecessary setter The class is handling all computations and cache access by itself now. So we can drop this method.

stablerange: directly perform slicing in the getting method Now that all necessary functions are available, we simply apply the standard slicing on cache miss and proceed.

stablerange: move standard slice point definition in main class More migration of code away from the doomed individual class.

stablerange: move the slicing method on the central class We migrate code away for the individual range class.

stablerange: move the range class in the new module Our ultimate goal is to remove this class for performance reason. however for now, it contains most of the code we care about so we migrate it as a block first.

stablesort: move into the stablerange module The stable range rely on the stable sort so it make senses to move it there. Will need direct access to it in the future.

subranges: migrate handling of single element range This is the simplest case by far, so we start with that one. We still use the rich object as an argument, but we'll do our best to not relying on that. This is important for performance reason.

stablerange: move the subrange cache into our new class This is the first step toward having more logic in that class

depth: extract code dedicated to depth of a merge in its own function The merge case is more complicated than the regular one, we extract is for the sake of clarity.

stablerange: move 'depth' inside a new 'stablerange' module The stablerange used for discovery requires significant amount of code. There is algorithme, cache, cache persistence, etc. So we create a dedicated module for it. The function is directly moved into a rich class handling cache (for now in memory) because we know we will need it.

obsdiscovery: document the status of the module I figured i would be useful to document what we expect from the code in each module.

split: move the debugcommand into a dedicated module The code related to debugobsstorestat is fairly independant, we move it into its own module.

legacy: move 'debugrecordpruneparents' in the extensions The transition is a couple of year old now, repository with the old format must be quite hard to find by now.

checks: correct the shebang line filtering for python files As it is, the only related file is docs/test2rst.py, which was covered by **.py. Not sure if it matters, but most patterns in core tests are for "#!.*?python". (Though there are a couple "#!.*python" tests.)

tests: add glob for Windows

tests: adds simple test case for heads checking This is the start of some systemic testing of the head superceeding detection mechanism.

tests: move exchange utility in testlib We have a testlib directory now lets use it.

exchange: fix some wrong reference to serveronly The function have all moved into 'obsexchange' now, so we do not need (and actually cannot) seek them in 'evolve.serveronly'.

checks: add a test that check MANIFEST.in content This make sure we keep the things updated.

README: add a link to mercurial devel This will help people to find the mailing list details.

README: tries to improve the title about server only This seems a bit better.

README: remove mention of make Using pip in all cases seems a better direction.

version: mark the current source as development version for 6.0.0 This is useful to distinguish the development version from the latest tagged version. In this particular case, this will allow us to publish a pre-version on pypi.

mercurial-3.8: merge with future evolve-6.0.0 We introduces the new code on the compat branch to check the tests.

mercurial-3.9: merge with hg-4.0 branch We merge with the code for the future evolve 6.0.0 code to check for compatibility. Only minor test output change (" -> ') have been noted.

mercurial-4.0: merge with future 6.0.0 A new version will be released soon, we start handling mismatch in test output to make the actual release time smoother.

checks: update pyflakes matching too We make sure to not select removed files.

checks: do not run pyflake on removed file The fileset matches removed files. This confuses pyflakes for good reasons.

compat: closing mercurial-3.7 compatibility branch The "evolve-6.0.0" release drop compatibility with Mercurial 3.7. No new commit are expected on this branch.

compat: closing mercurial-3.6 compatibility branch The "evolve-6.0.0" release drop compatibility with Mercurial 3.6. No new commit are expected on this branch.

compat: closing mercurial-3.4 compatibility branch The "evolve-6.0.0" release drop compatibility with Mercurial 3.4. No new commit are expected on this branch.

compat: closing mercurial-3.5 compatibility branch The "evolve-6.0.0" release drop compatibility with mercurial 3.5. No new commit are expected on this branch.

README: timeless typo fixes This applies some feedback timeless provided me from IRC.

cleanup: drop an empty section header

compat: drop some <hg-3.4 compatibility code The `hg commit` commands has a -i flag for ages now.

README: more update to prepare for pypi upload * mention the evolve.serveronly extension, * remove help related to topic into a different README file.

evolve: update the capabilities and commands name for obshashrange We makes is clear that these version are useful for earlier testing but they are not ready for any kind of real usage yet.

README: more change to have a pretty rendering on pypi We moves section around and fixes some markup.

MANIFEST.in: fix various mismatch check-manifest is no longer complaining

README: rework install instruction For both evolve and topic. The topic introduction is updated too.

README: rework the intro Less scary wording (similar to the wiki changes) and point to the user mailing list.

rangeobshash: minor cleanup of the obshash code We achieved minor speedup by delaying the hashing until we know it is needed.

stablerange: remove call to 'repo.revs' It turned out that the percentage of time spend parsing the revset string was two digits, so we compute de heads inline.

stablerange: reuse node calculation as much as possible We have a property cache with that value, so we just reuse it.

stablerange: adds some caching of the subranges The goal of subranges is to be as reusable as possible, so we cache the subrange relationship to take advantage of this.

stablerange: operate on an unfiltered repository We only do operation on ancestors so using unfiltered is fine.

depth: use lower lever function to compute missing The time spend parsing the revset is noticeable.

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.
