Deduplicate markers. Depends on __hash__ and __eq__ on obsolete.marker

copy precursor revset from evolve so we don't depend on involve

fastobs: details strategies in the main help

fastobs: fix a bunch of stupid errors that prevented it from working at all

fastobs: clean up logging a little

fastobs: first commit of an extension to test obsolete marker exchange methods This currently implements the "fill in the box" approach discussed at the 2.6 sprint, which seems to handle common cases correctly with significantly less data transferred.

drophack: add a new drop hack extension for Matt Mackall usage This extension is hacky and not intended for real world usage. See documentation for details.

prune: add biject option This option allows two ranges to be given for successors and precursors such that there is a one-to-one match between each range. Test coverage has been added.

evolve: register a summary hook instead of wrapping the summary command

merge stable into default.

doc: improve reference to log --hidden - glog is not mucha thing anymore - also add a usage exemple

doc: fix trailing white space

doc: DIE MQ DIE

doc: use --succ in prune help --succ is the new only way.

doc: remove referenc to proleferation of hidden commit This is not much something we try to avoid anymore This changeset is eathenly adding reference to other toubles too.

doc: try to clarify rebase warning

doc: enhance your fold help Refer to the two different for of using fold.

doc: refer to previous and next in the gup, gdown help

doc: replace graft -O with grab

doc: rework how to entry about amend We can recommand the core `hg commit --amend` now. We also drop reference to MQ.

raise util.Abort instead of assertion when trying to evolve a merge changeset. This prevent exposing a nasty traceback to the user.

merge with stable

tutorial: fix note We need a double semin colon, otherwise this is a comment.

tutorial: warn about rollback beeing obsolete

tutorial: use grab instead of rebase. grab as now the advantage to move the working directory.

tutorial Clarify "." explanation

tutorial: update divergent changeset section Still not there but less fuzy.

tutorial: use long form of argument for the sake of clarity

tutorial: fix some various typo

tutorial Display the help of appropriate command in section that need writting

doc: some documentation on the configuration part of the tutorial Trying to make it less obscure on first contact

doc: smarter make file We regenerate the tutorials when needed only

doc: use a symbolic link to point to the tutorial the file was lagging behind a ton.

import: warn about new unstable changesets 'hg import' can add new unstable changesets, for example when invoked with '--hidden' or '--exact', or when the working directory parent already is unstable.

evolve: show progress The total count may be too low on occasion. Not sure why. gaved up at testing this, can't get stable result.

removed the qsync extension. The only user I knew about (logilab) is not using it anymore. It not compatible with coming Mercurial version 2.9.

evolve: add more details when we abort for case not handled yet Verboser output to help people knowing what is going on and solving it on their own.

merge stable back into default

current release is stable enought

evolve: update the tested with statement It actually ssems to work with version up to 2.6 but some minor changes makes test fails. so better encourage people to upgrade.

evolve: use super for calling parent class method Otherwise we can bipass filtering (and break a lot of things)

debian: add source/format file

Added tag 3.2.0 for changeset c3ba8a965a7a

prepare 2.8 release

grab: update the alias for 2.8 compatibility 2.8 does not update on rebase anymore. We need to update by hand. this makes this alias more fragile.

gdown/gup: add next/previous alias Up and down refer to the customary order in log output rather than concepts; as such, it may be confusing to the user. I for one found them suprising -- they just didn't fit with my mental model. Previous and next, however, imply a clear parent/child relationship. We attroduce the new name as aliases for now.

evolve: allow updating to the successor if the parent is obsolete Although 'hg update' handles this as well, it will also update to tipmost descendent of the successor, if any.

evolve: abort on unknown divergent changeset base ...rather than noisily dying with a KeyError.

test: prepare test for core changeset 6cd9b8428104 Changeset 6cd9b8428104 in Mercurial core (2.8) make rebase preserve more extra. this mean hash changes. We make the test resilient to that.

test: prepare test for core changeset 9c78ed396075 New changeset in mercurial 2.8 (9c78ed396075) change rebase behavior to preverse the original working directory. This break an handfull of test so we preventively update to tip after rebase.

merge stable into default

add obsolete parents wrapper to the 'parents' command although the command itself cannot *cause* obsolete changesets, the information is rather relevant to the state of the parents

README: update changelog

conform to the Mercurial custom of lowercase messages ...and while at it, use the more usual long form of "can't"

amend: use core mechanism for amend Evolve used its own code for amending. This was introduced before mercurial includes commit --amend. The evolve code is now older and buggier. So we just use the core cod when amend is called. Message of the temporary commit is different, all test hash changed \o/. Test change are been carefully checked.

amend: drop the deprecated note option We plan to get closer to the commit --amend implementation dropping this deprecated option helps.

test: adapt to 2.6 message improvement From fd1bb7c1be78 (in core) hidden revision are excluded from partial match in a proper way resulting in a nicer error message.

README: polish the language so it reads better

README: fix spelling, capitalization, grammar, punctuation

evolve: drop "troubles" and "troubled" method now in core

test: drop rebase test We assume that the mercurial rebases tests suite is strong enough now.

doc: fix grammar, spelling, punctuation I restrained myself to making only changes that turn bad English into good English. There are still opportunities to improve, but other changes require some discussion and review. This change should be uncontroversial.

tutorial: fix grammar, spelling, punctuation I restrained myself to making only changes that turn bad English into good English. There are still opportunities to improve the tutorial, but other changes require some discussion and review. This change should be uncontroversial.
