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

locks to not be properly released, though Mercurial will usually
detect and remove such stale locks automatically.
However, detecting stale locks may not always be possible (for

Setting a lock will prevent other commands from changing the data.

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

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

A changeset that is made obsolete with no successors are called "pruned".
Such changesets have no successors sets at all.
A changeset that has been "split" will have a successors set containing
more than one successor.
A changeset that has been rewritten in multiple different ways is called
"divergent". Such changesets have multiple successor sets (each of which
may also be split, i.e. have multiple successors).
Results are displayed as follows::
<rev1>

def debugwireproto(ui, repo, **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``,
``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
Values are interpreted as Python b'' literals. This allows 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.
close
-----
Close the connection to the server.
flush
-----
Flush data written to the server.
readavailable
-------------
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.
