pull: use discovery to pull less obsmarkers through bundle2 This hooks in the official API for bundle2

pull: run obsmarker discovery only on the common set If the discovery is run before the obsmarker push, pulled revs does not exist in the repository yet.

evolve: fix a typo in a long function name

bundle2: burn some more of the old code Some of it survived.

obsexch: respect todosteps when using the old push

compat: update the tests after the jump

compat: use in-core encodemarkers Now exist in core witha slightly different format.

compat: rename encodeonemarkers to _fm0encodemarkers This is getting renamed in core.

enable bundle2

drop the debug output

test-simple4server: add error output for http This is useful in case of failure.

compat: adapt to change to memctx Since core mercurial 650b5b6e75ed we must return None instead of raising IOError. Hooray for mads!!

evolve: use pushkeyescape from core It exists for all version we are compatible with.

evolve: display more message

evolve: drop a very old safe guard about bad marker The do not clean marker with nullrev successors. I assume none of them remains.

pull: drop the custom bundle2 part

obsexc: add support for evoext_pushobsmarkers_0 on localpeer This will unify the behavior of exchange in the tests.

evolve: allow read() from the magic StringIO

evolve: drop old obsmarker discovery code It as not caller anymore.

obsexc: use the common discovery We drop the hand made discovery and rely on the general one introduced some time ago.

obsexc: push nothing if push fail This is closer to the future behavior with bundle2.

discovery: hook on the official discovery for obsmarker This will let the discovery be done once and used by core.

discovery: use a different setup step for discovery This will ease the dropping of the other part later.

evolve: remove unused drop random

obshash: resist to unknown revision during discovery

code movement: gather discovery code together The discovery code is the one thing that will survive the great purge.

bundle2: drop custom compat We'll rely on the core implementation to use bundle2.

drop relevant marker compat

evolve: always use the transaction version of phase movement This drop compat with all known released version of Mercurial.

evolve: drop debugobsoleterelevant Core gained this capability usig `hg debugobsolete --rev REV`

evolve: yield to relevant markers handling in core The handling of obsolescence marker is now performed in core. If we detect a mercurial with such power we skip the wrapping from evolve. This changeset also suffer from massive diff from the change in display of obsolescence marker with parent information introduced at the same time in core.

test-wireproto: adapt to output change from core

test: update test to new date formatting in debuobsolete output The date is now a first class citizen with proper formatting.

test: update help output to future 3.2

merge with stable

pkg: make tests pass using the generated tarball Exclude tests/test-drop.t and include tests/_exc-util.sh, tests/dummyssh, and hgext/simple4server.py.

compat: always call metadata as a keyword argument Those function are gaining more arguments. using keyword argument keep use safe in all version.

test: work around a bug in debugobsolete The defautl date was wrong all along. So we use a fixed date for all tests.

merge with stable

uncommit: add a --rev argument The uncommit command now taks a --rev argument. This lets restore the file content in the current commit to another revision (instead of just is parent content). This still does not touch the working directory content.\ This allow the longly awaited: hg uncommit --hidden --rev 'precursors(.)'

readme: add missing changelog entry My dear friends changelog.

import: handle patch with no node information patch created by old Mercurial version or other tool have no node information. We cannot create marker in this case.

import: compare binary node with binary node when using --obsolete hex(N) != N

Added tag 4.1.0 for changeset 4d5d101e878f

pkg: prepare release 4.1.0

merge default into stable Release 4.1.0 is coming

evolve: adds a --confirm option This option lets the use double check if it wants the evolve operation.

evolve: gather evolve output together We stop relying on ui.status being muted when --quiet is used. Instead we use plain write and hide this behind an explicite ui.quiet check. This will help use enforcing this output in the comming --confirm mode.

doc: forgotten amend

evolve: attempt to clarify the documentation around --all and --any This have been confusing to people. We try to be a bit more verbose in the evolve help.

evolve: re enable progress for all Progress is an important information for user facing slow push.

evolve: stop pretending we are pulling markers when we don't If discovery did not found any unknown marker, we should not display the "pulling marker" message.

evolve: do not even try to pull if all remote markers are known previously we were explicitly pulling an empty bundle.

evolve: add "obsolescence" in front of marked in the previous message

evolve: make the "X markers added" message during pull important

evolve: make the "pulling obsolescence marker" message important This is likely to take some time the user needs to know what is going on.

evolve: add "absolescence" in front of markers in the message

evolve: re-introduce the "pushing 42 markers…" message Informing the user about marker behind pushed sounds a good idea.

evolve: hide the OBSEXC message behind a config option This will lets most people ignore them while keep evolve dev having a close look at them. Some of the most useful messages will be reintroduced for all in coming changeset.

evolve: move OBSEXC progress in a dedicated function This will help use to rework them.

evolve: move OBSEXC message in a dedicated function This will help use to rework them.

Added tag 4.0.1 for changeset e914884fb721

evolve: prepare release 4.0.1

evolve: fix distribution for 4.0.0

evolve: update readme

evolve: update tested with statement

test: apply message changes introduced by mercurial 3.1

test: use `hg log` in the `getid` function using `hg id` to retrieve full lenght node requires to use --debug. This may include debug output (regarding branch cache invalidation for example) that breaks the test. We now use `hg log` with a custom template. This is a simple, clean and robust solution.

evolve: add a tr arguement to retractboundary Mercurial core is adding a transaction argument to its phase movement function. We do the same. If Mercurial appears to be an old version (without the extra args) we call it the old way.

relocate: add transaction around phase movement cheap way to acces access to the transaction object

uncommit tr

evolve: saner locking an transaction in `hg evolve` Each trouble solved used to handle locking and transaction on its own. We now have a top level locking and transaction. This will helps use making sure phase are moved within a transaction.

uncommit: saner locking scheme (and do it in the right order in the process)

prune: lock inside the try tss…

debugrecordpruneparents: release tr the same way than the lock Nicer code is nicer.

evolve: drop useless wlock in rewrite

divergence: actually use the hint that have been around for age Having a hint in the code is good, having it displayed is usually seens as better.

evolve: rename `tr` variable (for troubled) to `tro` tro is usually dedicated to transaction.

evolve: add a custom layer around retractboundary retract boundary is about to gain a new argument in core, we need somethign to handle this

merge with stable

evolve: point to the core mercurial tracker for bugfix As per Matt Mackall request evolution related bug should be filled again the main tracker as at some point al lof evolve wil be in core.

evolve: drop reference to 2.3 in the extension help text We are far away from 2.3 now.

readme: update the work in progress repository location

readme: update the official documentation location

evolve: deprecated --obsolete and --old-obsolete option on commit and graft Such option are unlikely to make it into core, so we deprecate them to avoid uer discovery them and getting used to them.

push: put phase in the same bundle2 than changegroup and obsmarkers Note that the usual phase push from core will be performed in all case. But the discovery should find already in sync phase at that time. The old ways sync will be properly skipped when this logic is introduced into core.

push: put obsmarkers in the same bundle2 than changeset When client is Mercurial 3.1 and server have proper evolve version and both side have bundle2 enabled, we'll includes a part containing obsolescence markers. When obsmarkers are included to the main bundle2 push, they will failed to be pushed if the changeset failed to be pushed (and reciprocally).

push: extract obsmarkers discovery in a dedicated function The need to factorise the computation of the markers to send in a dedicated function. This prepare the inclusion of obsmarkers in an atomic bundle2 push. For now, when obsmarkers are pushed using bundle2, they are still doing it on their own, in a dedicated bundle2 push.

evolve: update the tested with statement Tested with the soon to be release 3.1.

test: adapt to upstream message change A message gained parenthesis in 3.1 we reflect than in the test.

uncommit: improve error message for use with no arguments

test: use `hg log` in the `getid` function using `hg id` to retrieve full lenght node requires to use --debug. This may include debug output (regarding branch cache invalidation for example) that breaks the test. We now use `hg log` with a custom template. This is a simple, clean and robust solution.

readme: mention patchbomb usage and patch description guidelines on wiki

debian: add line to clean target to delete error files caused by failing tests

fold: improve error messages for multiple heads and roots This commit adds hints and i18n to the error messages about non-linear revisions, along with corresponding tests.

fold: reword error message for public commits This rewords the error message when attempting to fold public csets. It is somewhat clearer to not use contractions in formal writing. It also uses i18n for it. This commit also adds a new test for this error message.

fold: overhaul handling of revisions with --rev (BC) The fold command parsed the revision arguments in a very peculiar and idiosyncratic fashion: if revisions were passed without a --rev argument, then they would all be extended to ".", but if they were passed with --rev, then no extension would happen. Passing revisions both with and without --rev would abort. This is inconsistent with the way all other hg commands parse revision arguments. We have several examples of command where several revisions are passed, and the --rev option is optional for specifying those revisions (update, strip, export). This patch alters the way in which fold parses its revision arguments. No distinction is made between revisions passed with or without the --rev argument. Regardless if a single or multiple revision is specified, all will be folded together into the parent of the working directory. If the --exact argument is passed, then the parent of the working directory is ignored and the specified revisions must be a single contiguous line. The docstring and tests are modified accordingly.

fold: emit error message when folding a single revision Previously, a confusing error state would happen if the revision set to fold was a singleton.

fold: clarify message for empty revision set and abort instead (BC) I find it clearer that there are no revisions to fold because none were specified. Otherwise it seems ambiguous: maybe there are no revisions to fold because it's impossible to fold whatever was given? In analogy of other commands that are given no revisions (e.g. strip, graft), this is also now an abort instead of a mere error message, which is a BC.

evolve: do not use _ as an unused variable The _ variable is the i18n function from core Mercurial, so locally assigning to it can lead to name clashes.

test-obsolete: explicitly show which changesets are divergent

update readme (I should have a hook preventing me to push to public repo with uncommited changes)

evolve: add --tool option so we don't have to use HGMERGE

amend: add -U/--current-user option (inspired by mq)

tests: fix grammar, spelling, punctuation in comments

evolve: minor reorganisation of code responsible for evolve output This does not change any of the semantic as status is not printed when --quiet is provided. This juste make it more explicit that the output are related.

template: add a troubles keyword This keyword list all evolution troubles that affect a changeset. Evolution troubles can be "unstable", "divergent" and "bumped".

docs: update copyright statement used by sphinx

docs: add concepts guide (the set theory behind obsolescence)

docs: add guide to sharing mutable history

docs: add new user guide This has also been reviewed to death on evolve-testers. There are still a couple of short sections to write (clearly marked "TODO"), and one example to add. But (if I may be so bold) this is a gigantic improvement over the current docs, so it really should get merged. Incidentally, the figures are all SVG files created with Inkscape. They're not perfect, but they're pretty nice. Anyone who knows a better way to create technical diagrams is welcome to contribute. One wart: there's a test script that accompanies the document and largely duplicates it, but I haven't unified them. I've been concentrating on writing the best possible content, not on fiddling with tools. I suspect that unifying them will be non-trivial, but definitely worth doing.

docs: rewrite index page (including dangling links to future docs) This has been reviewed to death on the evolve-testers mailing list. I've made some minor tweaks since the last round of reviews, but the main content is the same.

amend: add -D/--current-date option, just like mq's qrefresh has Carefully designed so we can easily add -D to other changeset-creating commands (probably anything that takes -d), and so that we can add -U/--current-user as well. When that's done, the date and user options should be very similar to those in MQ.

amend: explicitly test -d option

amend: in tests, do not rely on defaults -- always use explicit -d Having a default -d option will make it hard to test -D/--current-date, which is coming shortly: presence of -d overrides -D, just like with mq's qrefresh.

evolve: fix createmarkers() wrapper to accept an iterable Docstring in mercurial.obsolete says "<relations> must be an iterable of ...", and hgsubversion takes it at its word and passes a generator. Until around Mercurial 3.0, this did not cause any problems, but now it does: in a repo with both evolve and hgsubversion enabled, pushing to Subversion when obsolete changesets are present causes a crash: [...] File "/home/gward/src/hgsubversion/hgsubversion/wrappers.py", line 346, in push obsolete.createmarkers(repo, relations) File "/home/gward/src/hg-stable/mercurial/extensions.py", line 196, in wrap return wrapper(origfn, *args, **kwargs) File "/home/gward/src/hg-evolve/hgext/evolve.py", line 332, in _createmarkers relations[idx] = (prec, sucs, meta) TypeError: 'generator' object does not support item assignment Since hgsubersion is playing by the documented rules, evolve must be the guilty party here.

simple4server: backport the bundle2 exchange

evolve: install progress support for the bundle2 pull path The custom wireprotocol command had a trick to display progress while pulling. We reinstall such logic for the new path using bundle2. Its notable that we are using the bundle2 advisory parameter for this purpose.

evolve: install progress support for the bundle2 push path The custom wireprotocol command had a trick to display progress while pushing. We reinstall such logic for the new path using bundle2.

evolve: add a pull path using bundle2 Instead of using a dedicated wireprotocol commands, we use bundle2 to transmit an obs marker parts. This aims at both testing bundle2 more and to limit the amount of special code we needs to put in simple for server to fit our needs. The massive test changes comes from the fact we can use this fast path for both remote and local push.

evolve: advertise obsmarker creation in the transation hook This will let extensions hooks on marker exchange.

evolve: add bytes and new marker data when processing part This will helps use to keep printing useful message when pulling through bundle2.

evolve: add a push pass using bundle2 Instead of using a dedicated wireprotocol commands, we use bundle2 to transmit an obs marker parts. This aims at both testing bundle2 more and to limit the amount of special code we needs to put in simple for server to fit our needs. The massive test changes comes from the fact we can use this fast path for both remote and local push.

evolve: make exchange output compact in the old pushkey case too.

evolve: compatibility with memfilectx change The future 3.1 have have more sophisticated memfilectx object. We add a compatibility layer for them.

evolve: abstract access to context.memfilectx This class is getting altered in the future Mercurial 3.1.0. This changeset prepare a compatibility layer.

import: drop version check for ``import --obsolete`` This code base does not support anything below mercurial-3.0 anyway.

evolve: more compact output in the wire protocol case We made the wording more similar and use less line. The writing operation is usually fast so we do not needs a specific line for it.

evolve: test exchange through wireprotocol The wireprotocol version of the exchange was only tested in the `simple4server.py` case.

evolve: align working during obsmarker push using pushkey lets use the same wording everywhere to prevent user confusion.

fold: add squash as a possible alias In order to respect the habituation of the majority of DVCS users and to make this feature more easily discoverable, the very common "squash" terminology should be added as a synonym to "fold". Since git does not have a squash command, this should be safe.

fold: add --message and --logfile options Like other commit-creating commands, this add two options for specifying the resulting commit message, with tests. If either of these options is specified, no editor is popped up asking for a commit message.

prune: update to successor rather than parent when prune '.'

import: --obsolete flag for automatic obsolescence marker creation A new `--obsolete` flag is added to import. When present, the new node will be marked as a successors of the one specified in the `Node` field of the imported patch. No marker are created when revision have the node expected in the patch. This improves email based work flow where implicit rebase are likely to happen and extra information are lost, changing the hash. This new behavior requires a flags, otherwise the `hg export x | hg import -` idiom would change, turning the source obsolete. (Changing from `hg graft x` to `hg rebase --dest . --rev x`) This change only takes effect when using Mercurial 3.0 and above

readme: the forgotten update strike again

evolve: protect call to rebase within a wlock (#42, #35, #16) Without a wlock, repo.commit would blow away the dirstate's parents on OSes that have no 'os.symlink' support in python, leading evolve to produce a merge instead of a rebase. If a user ran the rebase command instead of evolve, then things would work because rebase is wrapped in a giant wlock. Unfortunately, we can't use the same idea of wrapping the evolve command in one giant wlock because that's too early in the process. If the lock did wrap the entire evolve command, then the working directory would save its current parents which, since rebase hasn't been called yet, would be just p1. Therefore, we need to obtain the lock *after* the dirstate's parents are changed but *before* the call to rebase. This way ensures that when a conflict happens the working directory correctly shows both parent changeset.

run-tests: add executable bit

rewrite: use cmdutil.logmessage instead of ad-hoc methods The logic for handling the --message and --logfile options is already in core hg in the cmdutil.logmessage function. This patch removes this duplicate logic from Evolve and just calls the core function.

fold: enable --date and --user options Like all other commit-creating commits, `hg fold` should also have these options enabled. This also allows getting consistent hashes during tests involving fold.

exchange: dropping dead code (issue36) This variable does not exist anywhere else in the code.

evolve: fix evolve with mercurial default MODERNCAPS have been renamed to moderncaps upstream.

simple4server: update tests Forgot to amend before pushing.

sinmple4server: advertise new cap only when advertising obsolescence This is more consistent.

evolve: do not exchange obsolescence markers when server refuse it The server can be configured to refuse obsolescence markers exchange. See changeset 48804a8d7472 for details about it. We respect server will in the client.

simple4server: option to advertise obsolescence support We had an option to control the advertising of the obsolescence markers support from the server. The goal of this option is to allow large scale repo hosting service to control the use of obsolescence markers exchange.

export: add test for simple4server We now officially test it over http

exchange: fix push markers over wire protocol for http peer Http actually interpret the data passed to _callpush expecting them to a bundle. Interpretation of a markers stream as a bundle obviously led to crash.

exchange: expose length of pushed markers http wireprotocol will need it.

simple4server: update "from <changeset>" statement Could obviously not do it in the same changeset than the original changes.

exchange: fix changeset pulling over http http compress its stream. The were building a bogus stream where the first 10 bytes where uncompressed. Confusing the client.

simple4server: update "from <changeset>" statement Could obviously not do it in the same changeset than the original changes.

exchange: properly wrap wireprotocol capabilities Just wrapping the module function only works for ssh. Ssh gets capability through the `hello` command. We also need to wrap the function stored in the command dict. This fix discovery for http peer.

simple4server: add origin and documentation to most function
