debugcommands: use a revset instead of dagutil
All this code was doing was finding the nodes that are heads
from the ancestors of an input set. This can easily be expressed
with a revset without having to go through dagutil.
This was the last use of ancestorset() outside of dagutil itself.

Locks protect the integrity of Mercurial's data, so should be

detect and remove such stale locks automatically.
However, detecting stale locks may not always be possible (for

By default, all files known in the first parent context of the

options to limit target files. -r/--rev is also useful to examine
files in another context without actual updating to it.
With --debug, this command shows warning messages while matching
against ``merge-patterns`` and so on, too. It is recommended to
use this option with explicit file patterns and/or -I/-X options,
because this option increases amount of output per file according
to configurations in hgrc.
With -v/--verbose, this command shows configurations below at
first (only if specified).
- ``--tool`` option
- ``HGMERGE`` environment variable
- configuration of ``ui.merge``
If merge tool is chosen before matching against
``merge-patterns``, this command can't show any helpful

def debugwireproto(ui, repo, path=None, **opts):
"""send wire protocol commands to a server
This command can be used to issue wire protocol commands to remote
peers and to debug the raw data being exchanged.
``--localssh`` will start an SSH server against the current repository
and connect to that. By default, the connection will perform a handshake
and establish an appropriate peer instance.
``--peer`` can be used to bypass the handshake protocol and construct a
peer instance using the specified class type. Valid values are ``raw``,
``http2``, ``ssh1``, and ``ssh2``. ``raw`` instances only allow sending
raw data payloads and don't support higher-level command actions.
``--noreadstderr`` can be used to disable automatic reading from stderr
of the peer (for SSH connections only). Disabling automatic reading of
stderr is useful for making output more deterministic.
Commands are issued via a mini language which is specified via stdin.
The language consists of individual actions to perform. An action is
defined by a block. A block is defined as a line with no leading
space followed by 0 or more lines with leading space. Blocks are
effectively a high-level command with additional metadata.
Lines beginning with ``#`` are ignored.
The following sections denote available actions.
raw
---
Send raw data to the server.
The block payload contains the raw data to send as one atomic send
operation. The data may not actually be delivered in a single system
call: it depends on the abilities of the transport being used.
Each line in the block is de-indented and concatenated. Then, that
value is evaluated as a Python b'' literal. This allows the use of
backslash escaping, etc.
raw+
----
Behaves like ``raw`` except flushes output afterwards.
command <X>
-----------
Send a request to run a named command, whose name follows the ``command``
string.
Arguments to the command are defined as lines in this block. The format of
each line is ``<key> <value>``. e.g.::
command listkeys
namespace bookmarks
If the value begins with ``eval:``, it will be interpreted as a Python
literal expression. Otherwise values are interpreted as Python b'' literals.
This allows sending complex types and encoding special byte sequences via
backslash escaping.
The following arguments have special meaning:
``PUSHFILE``
When defined, the *push* mechanism of the peer will be used instead
of the static request-response mechanism and the content of the
file specified in the value of this argument will be sent as the
command payload.
This can be used to submit a local bundle file to the remote.
batchbegin
----------
Instruct the peer to begin a batched send.
All ``command`` blocks are queued for execution until the next
``batchsubmit`` block.
batchsubmit
-----------
Submit previously queued ``command`` blocks as a batch request.
This action MUST be paired with a ``batchbegin`` action.
httprequest <method> <path>
---------------------------
(HTTP peer only)
Send an HTTP request to the peer.
The HTTP request line follows the ``httprequest`` action. e.g. ``GET /foo``.
Arguments of the form ``<key>: <value>`` are interpreted as HTTP request
headers to add to the request. e.g. ``Accept: foo``.
The following arguments are special:
``BODYFILE``
The content of the file defined as the value to this argument will be
transferred verbatim as the HTTP request body.
``frame <type> <flags> <payload>``
Send a unified protocol frame as part of the request body.
All frames will be collected and sent as the body to the HTTP
request.
close
-----
Close the connection to the server.
flush
-----
Flush data written to the server.
readavailable
-------------
Close the write end of the connection and read all available data from
the server.
If the connection to the server encompasses multiple pipes, we poll both
pipes and read available data.
readline
--------
Read a line of output from the server. If there are multiple output
pipes, reads only the main pipe.
ereadline
---------
Like ``readline``, but read from the stderr pipe, if available.
read <X>
--------
``read()`` N bytes from the server's main output pipe.
eread <X>
---------
``read()`` N bytes from the server's stderr pipe, if available.
Specifying Unified Frame-Based Protocol Frames
----------------------------------------------
It is possible to emit a *Unified Frame-Based Protocol* by using special
syntax.
A frame is composed as a type, flags, and payload. These can be parsed
from a string of the form:
<request-id> <stream-id> <stream-flags> <type> <flags> <payload>
``request-id`` and ``stream-id`` are integers defining the request and
stream identifiers.
``type`` can be an integer value for the frame type or the string name
of the type. The strings are defined in ``wireprotoframing.py``. e.g.
``command-name``.
``stream-flags`` and ``flags`` are a ``|`` delimited list of flag
components. Each component (and there can be just one) can be an integer
or a flag name for stream flags or frame flags, respectively. Values are
resolved to integers and then bitwise OR'd together.
``payload`` represents the raw frame payload. If it begins with
``cbor:``, the following string is evaluated as Python code and the
resulting object is fed into a CBOR encoder. Otherwise it is interpreted
as a Python byte string literal.
