compat: drop 4.3 compatiblity code for 'precursors' revset

compat: drop Mercurial 4.3 support for exthelper The last release email noted plans to drop 4.3 and 4.4 support in the next feature release. I'd like to move this code into core, and dropping this should allow the class to be copied in unmodified.

compat: update metadata about minimum ag version

next: solve the issue of `next` get confused by split This patch solve a problem of next command which get confused by split. Let me describe how it was getting confused: Initial state of repo: A---B---C After splitting B to (B1,B2): @ A---B1---B2 \ ---B---C X * (note: C is orphan; checkedout to B1) Lets make an amend on B1: @ B1' / A---B1---B2 \ X * \ ---B---C X * Now, if run `hg next` (--evolve is True by default now): $ it would give you choice to choose from B2 and C thinking that C could also be a possbile children for B1, instead of stablizing B2 on B1. I fixed this problem by filtering those aspiring children which can be stablized on one of the aspiring children itself. Changes made in test-prev-next.t shows the changed expected behaviour.

next: add test which shows that `next` get confused by split

cleanup: avoid a Yoda condition

evolve: modify and move the comment to appropriate position

next: update the command description Now, if necessary next command evolve the next child revision by defualt. You don't need to pass the --evolve flag.

next: make next command --evolve by default Before this patch, if we need to evolve to update to the next child, we were suggesting the user to use --evolve flag. This patch make some changes to evolve by default in that conditions. After making next command to evolve by default we have to consider the following points: 1) If we don't need to evolve while updating to the next child: a) And if wdir is dirty, we suggest to use --merge flag b) if wdir is clean, we simply update to next child (if ambiguous, prompt the user to select one) 2) If we need to evolve: a) when wdir is dirty, we suggest the user to use `hg shelve` first, to make wdir clean. As we don't support --merge while evovling. b) when wdir is clean, we evolve the next cset. Changes made in test-prev-next.t reflect the changed behaviour.

safeguard: allow push to succeed (and without warning) with --publish

topic: only add --publish flag to push if it's not already there

safeguard: check auto-publish value before sending listkeys command Always sending listkeys command is just wasteful, let's first make sure users even care about auto-publish behavior.

style: silence another flak8 warning Default should be green now.

oops: backed out changeset df22f010cf24 pushed by error The changeset still fails some test

As we don't support --merge while evovling. b) when wdir is clean, we evolve the next cset. Changes made in test-prev-next.t reflect the changed behaviour.

next: improve the message for dirty working copy with --evolve This will be important soon when --evolve will be the default.

next: use the `hint` argument of bail if changed The argument is availabel since Mercurial 4.1. So let's use it.

prev: use the `hint` argument of bail if changed The argument is availabel since Mercurial 4.1. So let's use it.

next: explicitly specify --no-evolve in the tests The default value for this flag is about to switch.

branching: merge with stable

style: fix various flake8 warning

next: set if we need to evolve or not; also move logic to appropriate pos set the value `needevolve` and also move the logic to find aspiringchildren to appropriate position i.e before we suggest user to use other flags like --merge.

next: move some code to prepare for `next --evolve` by default Moved some values before the block where we suggest the user to use --merge flag. As we would need these values to find if we need to evolve or not before we can suggest user to use `--merge` flag. We will suggest user to use `--merge` flag only when we don't need to evolve. Because currently we don't support both --evolve(going to be True by default) and --merge at the same time.

branching: merge with stable

topic: improve UX by using pager only when we should Before this patch we were using pager in every case of topic command, either it is setting up a new topic or clearing the active topic. After this patch it will not use pager in following commands: $ hg topic [TOPIC] -r [rev] $ hg topic --clear

evolvecmd: _possibledestination() skip visiting empty parent I see that even in the case when "parent == -1" we are visiting that also and find succsets for that and in last -1 is being added in the set of possible destination. Why not skip that?

pick: `hg help` was not showing the full cmd desc of `pick` after running command `hg help` it was not including the second line of command description. I guess it picks the firstline only. So I moved that part in first line of cmd description.
