evolve: improve the help message of --rev User's are not exposed to the notion of revset, this patch makes the help message more intelligible.

evolve: add --rev option to the evolve command This patch is part of a series of patches to refactor the evolve method and make it more readable. We introduce a new --rev flag to specify a revset where to solve the troubles instead of looking from the parent changeset. All add a test checks that --rev works with several commits

evolve: extract cleanup logic in the evolve function We are going to need to reuse the cleanup logic when introducing --rev, so we extract it in a method to avoid code duplication.

evolve: simplify the evolve function We compute the troubles once and use it in two places instead of recomputing them just to count them.

evolve: optimize the computation of the troubled() revset We take the implementation from _counttroubles() and rely on the more efficient & operation for revset instead of laying down the entire set with %ld.

inhibit: don't inhibit pinned commits during rebase During a rebase we pin certain commits to always be visible. This caused the inhibit extension to inhibit them when a transaction closed. Let's make inhibit aware of such pins and not obsolete them.

evolve: extract the logic to solve one change into a method The goal is to later reuse this method to implement the --rev flag for evolve that solves the troubles in a revset.

evolve: add new variable and comment Add comment and introduce a new variable to keep track of if the progress ui is shown. Later on we will use this variable in the implementation of the --rev option.

evolve: move code to track progress and start node This makes it easier to refactor the evolve function in this serie of patches.

evolve: renaming of a variable tro was not a really descriptive name, replacing it with nexttrouble.

evolve: refactoring of the code displaying error when no trouble found Before this patch, we had many return statements in the evolve function especially in the part in charge of displaying errors when no troubles were found. We move this code in a separate function.

evolve: refactor code computing stats of obsolescence markers Duplicated code removal by extracting a function.

evolve: refactoring of code related to pushing obs markers This removes duplicated code for the pushobsmarkers logic

merge with stable bunch of cleanup on stable

update readme

evolve: update cmddebugrecordpruneparents to the new markers creation API The parents information are now first class citizen. (caught by laurent using pylint)

evolve: drop useless return This return statement is never reached. This a actually a good new because its variable was undefined. We remove it. (caught by laurent using pylint)

evolve: add missing import (caught by pylint)

evolve: improve transaction related code to use the lock module Refactored some of the places where we are using locking in evolve to use the lock module and write less code. This should also fix a couple of bug where tr could be None at release time.

evolve: remove unused variables As suggested by pyflakes, remove 5 unused variables in the evolve module.

evolve: remove unused code in _evolveany remove some code that was doing nothing useful in _evolveany.

evove: remove unused imports Three imports where unused in the evolve module.

tests: ensure we keep capturing output In 3.4, output capture with bundle2 is disabled by default on local push.

inhibit: updating to a obsolete commit prints warning message We move the inhibition marker in the same wlock than the update operation, this clears the warning message. To make it work we display the warning message on lock release in evolve.
