Summary: See PHI2085. Python 3 is stricter about integers and floats than Python 2 was, and we can end up passing a float where an integer was expected if the player wins "arc anoid" using a terminal with certain (most?) character dimensions.
Test Plan:
- Modified "arcanoid.py" to win instantly.
- Adjusted terminal window to 80x24, ran "arc anoid", reproduced crash.
- Ran "python2 arcanoid.py" and observed old victory animation behavior.
- Applied patch.
- Ran "arc anoid" and observed identical victory animation behavior.

Summary:
Ref T13649. Currently, "arc" may leave stdin nonblocking after showing a prompt. This can cause various odd behaviors down the line.
I can't immediately reproduce this behavior on macOS in "zsh" or "bash" (I'm unable to get stdin to remain nonblocking beyond the process lifespan), and also don't have pcntl locally so there's a fair amount of handwaving here.
Test Plan: This is somewhat speculative since I can't immediately reproduce the behavior. I tested the locally-reachable paths (no pcntl) but they're not interesting.

Summary:
Ref T13576. See that task for discussion.
When a user runs `arc land --pick A`, they may be selecting a range of commits ("X..Y") which have ancestors ("V..W") that should NOT land.
We must slice "X..Y" out of history before we can merge it, to avoid landing changes from "V..W".
When "X..Y" is simple and linear, we can rebase the range to pick our desired slice out of history.
When "X..Y" includes merge commits, we frequently can not, and I could not identify any simple alternative. The best alternative I came up with is this "reduce" operation:
- squash "into" onto Y, producing S, to guarantee there are no natural conflicts;
- squash S onto X^, producing T, to get rid of the merge commits;
- rebase T onto "into", producing R, to slice "X..Y" out of history;
- squash R onto "into", producing Q. (R and Q will be the same, but this simplies the code.)
This feels flimsy and fragile, but I can't immediately find a way to break it. See T13576 for more discussion.
Test Plan:
- Applied conflicting changes to `example.txt` in `master` and `feature1`.
- Ran `arc land`, got a merge conflict.
- Resolved the conflict with `git merge master`.
- Ran `arc land`.
- Before: merge conflict.
- After: `arc land` resolves the merge correctly.
- Stacked `feature2` on `feature1`, and made various mutations to `feature1` and `feature2`, then ran `arc land --pick feature2`. Changes made in `feature1` should not land, and they mostly do not. See T13576.

Summary:
PHP 8's sprintf raises a ValueError when encountering unknown format
specifiers (previously it would eat the argument and print nothing), so
linting format strings like %Ls dies with an uncaught ValueError.
Fix this by using a custom callback during linting to turn all format
specifiers into %s and replace the dummy null argument with the original
format specifier, ensuring we always end up providing valid input to the
sprintf at the end. This has the nice property that the output of the
call to xsprintf is the original format string, though any
transformation into valid input would do.

Ref T13555. Currently:
- If an exception is raised in "start()", the exception state is not set on the future.
- Futures do not always call "startFuture()" before starting, and do not always call "endFuture()" once they become resolvable.
- If you start an ExecFuture which immediately fails and then call "getPID()" on it, you get an unclear exception.
Simplify these behaviors:
- In FutureIterator, only start futures which have not already started.
- When starting a future on any pathway, run start code.
- When a future becomes resolvable on any pathway, run end code.
- Raise a more clear exception when calling "getPID()" on a future with no subprocess.

Summary:
See PHI1808. Currently, "arc land <some bookmark>" does not destroy the bookmark in Mercurial. There are three issues here:
- "hg rebase --keep --collapse" moves bookmarks to the rewritten commits;
- "hg strip" moves bookmarks backwards;
- "hg prune" moves bookmarks backwards.
To get around "hg rebase", save and restore bookmark state.
To get around "hg strip" and "hg prune", explicitly destroy bookmarks pointing at commits before we strip/prune those commits.
Test Plan:
- Ran "arc land <some bookmark> --trace". Saw arc reset the bookmark position after rebasing, and destroy the bookmark explicitly before stripping.
- When the workflow exited, saw no more bookmark (previously: bookmark existed and pointed at a possibly-intermediate state).
Differential Revision: https://secure.phabricator.com/D21397
Summary:
Ref PHI1808. In Mercurial, we must save and restore bookmark state explicitly.
- Save and restore bookmarks.
- Clean up concepts in "arc-ls-markers" slightly, so we don't need separate "isCurrent" and "isActive" flags, hopefully.
I believe the totality of Mercurial state is:
- A (non-bare) working copy points at exactly one commit (which might be the empty/null commit, in an empty repository).
- A working copy has exactly one active branch.
- Each branch has zero or more heads.
- Each head may be closed.
- Each (non-null) commit belongs to exactly one branch.
- Note that the active branch may have zero heads and zero commits which belong to it!
- A working copy has zero or one active bookmark.
To capture this, we now emit:
- A list of branch heads. If a branch head is a working copy commit, that head is flagged as active.
- A list of bookmarks. If a bookmark is the current bookmark, that bookmark is flagged as active.
- A single "branch-state" virtual marker. This covers the case where you have run "hg branch X" to create X, but no objects in the working copy actually correspond to X yet. It also covers the case where you are on a concrete branch, but not any head of that branch.
- A single "commit-state" virtual marker. This always shows the current commit in the working copy.
Test Plan:
- Useful states to test are:
- Empty repository (not all commands currently work here).
- Normal repository, on a bookmark.
- Normal repository, no bookmark.
- "hg up 123" to update to somewhere in history.
- "hg branch X", to start a new branch with no commits.
- Ran "arc branches" and "arc bookmarks" in various states. Saw generally sensible output.
- Ran "arc land --hold ..." in various states against a failing remote. Saw generally sensible output, and saw working properly restored to the original state.
