commands: rename clone --uncompressed to --stream and document

--uncompressed isn't a very good name and its description in the
help documentation isn't very useful. We refer to this concept as
"stream clones" in a number of places. I think it makes sense to
change the user-facing argument to use the mode --stream. So this
commit does that.

We keep --uncompressed around for backwards compatibility.

While we're here, we overhaul the help docs for streaming clones
to be somewhat useful.

All tests have been updated to reflect the new preferred --stream
argument. A test for backwards compatibility of --uncompressed has
been added.

.. bc::

   `hg clone --stream` should now be used instead of --uncompressed.

   --uncompressed is marked as deprecated and is an alias for --stream.
   There is no schedule for elimination of --uncompressed.

       working directory and a new child of REV that simply undoes REV.
 
       Before version 1.7, the behavior without --merge was equivalent
       to specifying --merge followed by :hg:`update --clean .` to
       cancel the merge and leave the child of REV as a head to be
       merged separately.
 
     See :hg:`help dates` for a list of formats valid for -d/--date.
 
     See :hg:`help revert` for a way to restore files to the state
     of another revision.
 
     Returns 0 on success, 1 if nothing to backout or there are unresolved
     files.

     This command helps to find changesets which introduce problems. To
     use, mark the earliest changeset you know exhibits the problem as
     bad, then mark the latest changeset which is free from the problem
     as good. Bisect will update your working directory to a revision
     for testing (unless the -U/--noupdate option is specified). Once
     you have performed tests, mark the working directory as good or
     bad, and bisect will either update to another candidate changeset
     or announce that it has found the bad revision.
 
     As a shortcut, you can also use the revision argument to mark a
     revision as good or bad without checking it out first.
 
     If you supply a command, it will be used for automatic bisection.
     The environment variable HG_NODE will contain the ID of the
     changeset being tested. The exit status of the command will be
     used to mark revisions as good or bad: status 0 means good, 125
     means to skip the revision, 127 (command not found) will abort the
     bisection, and any other non-zero exit status means the revision
     is bad.
 
     .. container:: verbose
 
       Some examples:
 
       - start a bisection with known bad revision 34, and good revision 12::
 
           hg bisect --bad 34
           hg bisect --good 12
 
       - advance the current bisection by marking current revision as good or
         bad::
 
           hg bisect --good
           hg bisect --bad
 
       - mark the current revision, or a known revision, to be skipped (e.g. if
         that revision is not usable because of another issue)::
 
           hg bisect --skip
           hg bisect --skip 23
 
       - skip all revisions that do not touch directories ``foo`` or ``bar``::
 
           hg bisect --skip "!( file('path:foo') & file('path:bar') )"
 
       - forget the current bisection::
 
           hg bisect --reset
 
       - use 'make && make tests' to automatically find the first broken
         revision::
 
           hg bisect --reset
           hg bisect --bad 34
           hg bisect --good 12
           hg bisect --command "make && make tests"
 
       - see all changesets whose states are already known in the current
         bisection::
 
           hg log -r "bisect(pruned)"
 
       - see the changeset currently being bisected (especially useful
         if running with -U/--noupdate)::
 
           hg log -r "bisect(current)"
 
       - see all changesets that took part in the current bisection::
 
           hg log -r "bisect(range)"
 
       - you can even get a nice graph::
 
           hg log --graph -r "bisect(range)"
 
       See :hg:`help revisions.bisect` for more about the `bisect()` predicate.

     Bookmarks are labels on changesets to help track lines of development.
     Bookmarks are unversioned and can be moved, renamed and deleted.
     Deleting or moving a bookmark has no effect on the associated changesets.
 
     Creating or updating to a bookmark causes it to be marked as 'active'.
     The active bookmark is indicated with a '*'.
     When a commit is made, the active bookmark will advance to the new commit.
     A plain :hg:`update` will also advance an active bookmark, if possible.
     Updating away from a bookmark will cause it to be deactivated.
 
     Bookmarks can be pushed and pulled between repositories (see
     :hg:`help push` and :hg:`help pull`). If a shared bookmark has
     diverged, a new 'divergent bookmark' of the form 'name@path' will
     be created. Using :hg:`merge` will resolve the divergence.
 
     Specifying bookmark as '.' to -m or -d options is equivalent to specifying
     the active bookmark's name.
 
     A bookmark named '@' has the special property that :hg:`clone` will
     check it out by default if it exists.
 
     .. container:: verbose
 
       Examples:
 
       - create an active bookmark for a new line of development::

        light-weight bookmark instead. See :hg:`help glossary` for more
        information about named branches and bookmarks.
 
     With no argument, show the current branch name. With one argument,
     set the working directory branch name (the branch will not exist
     in the repository until the next commit). Standard practice
     recommends that primary development take place on the 'default'
     branch.
 
     Unless -f/--force is specified, branch will not let you set a
     branch name that already exists.
 
     Use -C/--clean to reset the working directory branch to that of
     the parent of the working directory, negating a previous branch
     change.
 
     Use the command :hg:`update` to switch to an existing branch. Use
     :hg:`commit --close-branch` to mark this branch head as closed.
     When all heads of a branch are closed, the branch will be
     considered closed.

     If no destination directory name is specified, it defaults to the
     basename of the source.
 
     The location of the source is added to the new repository's
     ``.hg/hgrc`` file, as the default to be used for future pulls.
 
     Only local paths and ``ssh://`` URLs are supported as
     destinations. For ``ssh://`` destinations, no working directory or
     ``.hg/hgrc`` will be created on the remote side.
 
     If the source repository has a bookmark called '@' set, that
     revision will be checked out in the new repository by default.
 
     To check out a particular version, use -u/--update, or
     -U/--noupdate to create a clone with no working directory.
 
     To pull only a subset of changesets, specify one or more revisions
     identifiers with -r/--rev or branches with -b/--branch. The
     resulting clone will contain only the specified changesets and
     their ancestors. These options (or 'clone src#rev dest') imply
     --pull, even for local source repositories.
 
+    In normal clone mode, the remote normalizes repository data into a common
+    exchange format and the receiving end translates this data into its local
+    storage format. --stream activates a different clone mode that essentially
+    copies repository files from the remote with minimal data processing. This
+    significantly reduces the CPU cost of a clone both remotely and locally.
+    However, it often increases the transferred data size by 30-40%. This can
+    result in substantially faster clones where I/O throughput is plentiful,
+    especially for larger repositories. A side-effect of --stream clones is
+    that storage settings and requirements on the remote are applied locally:
+    a modern client may inherit legacy or inefficient storage used by the
+    remote or a legacy Mercurial client may not be able to clone from a
+    modern Mercurial remote.
+
     .. note::
 
        Specifying a tag will include the tagged changeset but not the
        changeset containing the tag.
 
     .. container:: verbose
 
       For efficiency, hardlinks are used for cloning whenever the
       source and destination are on the same filesystem (note this
       applies only to the repository data, not to the working
       directory). Some filesystems, such as AFS, implement hardlinking
       incorrectly, but do not report errors. In these cases, use the
       --pull option to avoid hardlinking.
 
       Mercurial will update the working directory to the first applicable
       revision from this list:
 
       a) null if -U or the source repository has no changesets
       b) if -u . and the source repository is local, the first parent of
          the source repository's working directory
       c) the changeset specified with -u (if a branch name, this means the
          latest head of that branch)
       d) the changeset specified with -r
       e) the tipmost head specified with -b
       f) the tipmost head specified with the url#branch source syntax
       g) the revision marked with the '@' bookmark, if present
       h) the tipmost head of the default branch
       i) tip
 
       When cloning from servers that support it, Mercurial may fetch
       pre-generated data from a server-advertised URL. When this is done,
       hooks operating on incoming changesets and changegroups may fire twice,
       once for the bundle fetched from the URL and another for any additional
       data not fetched from this URL. In addition, if an error occurs, the
       repository may be rolled back to a partial clone. This behavior may
       change in future releases. See :hg:`help -e clonebundles` for more.
 
       Examples:
 
       - clone a remote repository to a new directory named hg/::
 
           hg clone https://www.mercurial-scm.org/repo/hg/
 
       - create a lightweight local clone::
 
           hg clone project/ project-feature/
 
       - clone from an absolute path on an ssh server (note double-slash)::
 
           hg clone ssh://user@server//home/projects/alpha/
 
-      - do a high-speed clone over a LAN while checking out a
-        specified version::
-
-          hg clone --uncompressed http://server/repo -u 1.5
+      - do a streaming clone while checking out a specified version::
+
+          hg clone --stream http://server/repo -u 1.5
 
       - create a repository without changesets after a particular revision::

     '''copy changes from other branches onto the current branch
 
     This command uses Mercurial's merge logic to copy individual
     changes from other branches without merging branches in the
     history graph. This is sometimes known as 'backporting' or
     'cherry-picking'. By default, graft will copy user, date, and
     description from the source changesets.
 
     Changesets that are ancestors of the current revision, that have
     already been grafted, or that are merges will be skipped.
 
     If --log is specified, log messages will have a comment appended
     of the form::
 
       (grafted from CHANGESETHASH)
 
     If --force is specified, revisions will be grafted even if they
     are already ancestors of or have been grafted to the destination.
     This is useful when the revisions have since been backed out.
 
     If a graft merge results in conflicts, the graft process is
     interrupted so that the current merge can be manually resolved.
     Once all conflicts are addressed, the graft process can be
     continued with the -c/--continue option.
 
     .. note::
 
        The -c/--continue option does not reapply earlier options, except
        for --force.
 
     .. container:: verbose
 
       Examples:
 
       - copy a single change to the stable branch and edit its description::
 
           hg update stable
           hg graft --edit 9393
 
       - graft a range of changesets with one exception, updating dates::
 
           hg graft -D "2085::2093 and not 2091"
 
       - continue a graft after resolving conflicts::
 
           hg graft -c
 
       - show the source of a grafted changeset::
 
           hg log --debug -r .
 
       - show revisions sorted by date::
 
           hg log -r "sort(all(), date)"

     Import a list of patches and commit them individually (unless
     --no-commit is specified).
 
     To read a patch from standard input (stdin), use "-" as the patch
     name. If a URL is specified, the patch will be downloaded from
     there.
 
     Import first applies changes to the working directory (unless
     --bypass is specified), import will abort if there are outstanding
     changes.
 
     Use --bypass to apply and commit patches directly to the
     repository, without affecting the working directory. Without
     --exact, patches will be applied on top of the working directory
     parent revision.
 
     You can import a patch straight from a mail message. Even patches
     as attachments work (to use the body part, it must have type
     text/plain or text/x-patch). From and Subject headers of email
     message are used as default committer and commit message. All
     text/plain body parts before first diff are added to the commit
     message.
 
     If the imported patch was generated by :hg:`export`, user and
     description from patch override values from message headers and
     body. Values given on command line with -m/--message and -u/--user
     override these.
 
     If --exact is specified, import will set the working directory to
     the parent of each patch before applying it, and will abort if the
     resulting changeset has a different ID than the one recorded in
     the patch. This will guard against various ways that portable
     patch formats and mail systems might fail to transfer Mercurial
     data or metadata. See :hg:`bundle` for lossless transmission.
 
     Use --partial to ensure a changeset will be created from the patch
     even if some hunks fail to apply. Hunks that fail to apply will be
     written to a <target-file>.rej file. Conflicts can then be resolved
     by hand before :hg:`commit --amend` is run to update the created
     changeset. This flag exists to let people import patches that
     partially apply without losing the associated metadata (author,
     date, description, ...).
 
     .. note::
 
        When no hunks apply cleanly, :hg:`import --partial` will create
        an empty changeset, importing only the patch metadata.
 
     With -s/--similarity, hg will attempt to discover renames and
     copies in the patch in the same way as :hg:`addremove`.
 
     It is possible to use external patch programs to perform the patch
     by setting the ``ui.patch`` configuration option. For the default
     internal tool, the fuzz can also be configured via ``patch.fuzz``.
     See :hg:`help config` for more information about configuration
     files and how to use these options.
 
     See :hg:`help dates` for a list of formats valid for -d/--date.
 
     .. container:: verbose
 
       Examples:
 
       - import a traditional patch from a website and detect renames::
 
           hg import -s 80 http://example.com/bugfix.patch
 
       - import a changeset from an hgweb server::
 
           hg import https://www.mercurial-scm.org/repo/hg/rev/5ca8c111e9aa
 
       - import all the patches in an Unix-style mbox::
 
           hg import incoming-patches.mbox
 
       - import patches from stdin::
 
           hg import -
 
       - attempt to exactly restore an exported changeset (not always
         possible)::
 
           hg import --exact proposed-fix.patch
 
       - use an external tool to apply a patch which is too fuzzy for
         the default internal tool.
 
           hg import --config ui.patch="patch --merge" fuzzy.patch
 
       - change the default fuzzing from 2 to a less strict 7
 
           hg import --config ui.fuzz=7 fuzz.patch
 
     Returns 0 on success, 1 on partial success (see --partial).

     Push changesets from the local repository to the specified
     destination.
 
     This operation is symmetrical to pull: it is identical to a pull
     in the destination repository from the current one.
 
     By default, push will not allow creation of new heads at the
     destination, since multiple heads would make it unclear which head
     to use. In this situation, it is recommended to pull and merge
     before pushing.
 
     Use --new-branch if you want to allow push to create a new named
     branch that is not present at the destination. This allows you to
     only create a new branch without forcing other changes.
 
     .. note::
 
        Extra care should be taken with the -f/--force option,
        which will push all new heads on all branches, an action which will
        almost always cause confusion for collaborators.
 
     If -r/--rev is used, the specified revision and all its ancestors
     will be pushed to the remote repository.
 
     If -B/--bookmark is used, the specified bookmarked revision, its
     ancestors, and the bookmark will be pushed to the remote
     repository. Specifying ``.`` is equivalent to specifying the active
     bookmark's name.
 
     Please see :hg:`help urls` for important details about ``ssh://``
     URLs. If DESTINATION is omitted, a default path will be used.
 
     .. container:: verbose
 
         The --pushvars option sends strings to the server that become
         environment variables prepended with ``HG_USERVAR_``. For example,
         ``--pushvars ENABLE_FEATURE=true``, provides the server side hooks with
         ``HG_USERVAR_ENABLE_FEATURE=true`` as part of their environment.
 
         pushvars can provide for user-overridable hooks as well as set debug
         levels. One example is having a hook that blocks commits containing
         conflict markers, but enables the user to override the hook if the file
         is using conflict markers for testing purposes or the file format has
         strings that look like conflict markers.
 
         By default, servers will ignore `--pushvars`. To enable it add the
         following to your configuration file::
 
             [push]
             pushvars.server = true
 
     Returns 0 if push was successful, 1 if nothing to push.

     Merges with unresolved conflicts are often the result of
     non-interactive merging using the ``internal:merge`` configuration

     command is used to manage the files involved in a merge, after

     working directory must have two parents). See :hg:`help
     merge-tools` for information on configuring merge tools.
 
     The resolve command can be used in the following ways:
 
     - :hg:`resolve [--tool TOOL] FILE...`: attempt to re-merge the specified
       files, discarding any previous merge attempts. Re-merging is not
       performed for files already marked as resolved. Use ``--all/-a``
       to select all unresolved files. ``--tool`` can be used to specify
       the merge tool used for the given files. It overrides the HGMERGE
       environment variable and your configuration files.  Previous file
       contents are saved with a ``.orig`` suffix.
 
     - :hg:`resolve -m [FILE]`: mark a file as having been resolved
       (e.g. after having manually fixed-up the files). The default is
       to mark all unresolved files.
 
     - :hg:`resolve -u [FILE]...`: mark a file as unresolved. The
       default is to mark all resolved files.
 
     - :hg:`resolve -l`: list files which had or still have conflicts.
       In the printed list, ``U`` = unresolved and ``R`` = resolved.
       You can use ``set:unresolved()`` or ``set:resolved()`` to filter
       the list. See :hg:`help filesets` for details.
 
     .. note::
 
        Mercurial will not let you commit files with unresolved merge
        conflicts. You must use :hg:`resolve -m ...` before you can

     This restores the contents of files to an unmodified

     Using the -r/--rev or -d/--date options, revert the given files or
     directories to their states as of a specific revision. Because
     revert does not change the working directory parents, this will
     cause these files to appear modified. This can be helpful to "back
     out" some or all of an earlier change. See :hg:`backout` for a
     related method.
 
     Modified files are saved with a .orig suffix before reverting.
     To disable these backups, use --no-backup. It is possible to store
     the backup files in a custom directory relative to the root of the
     repository by setting the ``ui.origbackuppath`` configuration

     Please use :hg:`commit --amend` instead of rollback to correct

     This command should be used with care. There is only one level of
     rollback, and there is no way to undo a rollback. It will also
     restore the dirstate at the time of the last transaction, losing
     any dirstate changes since that time. This command does not alter
     the working directory.
 
     Transactions are used to encapsulate the effects of all commands
     that create new changesets or propagate existing changesets into a
     repository.
 
     .. container:: verbose
 
       For example, the following commands are transactional, and their
       effects can be rolled back:
 
       - commit
       - import
       - pull
       - push (with this repository as the destination)
       - unbundle
 
       To avoid permanent data loss, rollback will refuse to rollback a
       commit transaction if it isn't checked out. Use --force to
       override this protection.
 
       The rollback command can be entirely disabled by setting the
       ``ui.rollback`` configuration setting to false. If you're here
       because you want to use rollback and it's disabled, you can
       re-enable the command by setting ``ui.rollback`` to true.
 
     This command is not intended for use on public repositories. Once
     changes are visible for pull by other users, rolling a transaction
     back locally is ineffective (someone else may already have pulled
     the changes). Furthermore, a race is possible with readers of the
     repository; for example an in-progress pull from the repository
     may fail if a rollback is performed.

     the source of a copy/move operation, are not listed unless
     -c/--clean, -i/--ignored, -C/--copies or -A/--all are given.
     Unless options described with "show only ..." are given, the
     options -mardu are used.
 
     Option -q/--quiet hides untracked (unknown and ignored) files
     unless explicitly requested with -u/--unknown or -i/--ignored.
 
     .. note::
 
        :hg:`status` may appear to disagree with diff if permissions have
        changed or a merge has occurred. The standard diff format does
        not report permission changes and diff only reports changes
        relative to one merge parent.
 
     If one revision is given, it is used as the base revision.
     If two revisions are given, the differences between them are
     shown. The --change option can also be used as a shortcut to list
     the changed files of a revision from its first parent.
 
     The codes used to show the status of files are::
 
       M = modified
       A = added
       R = removed
       C = clean
       ! = missing (deleted by non-hg command, but still tracked)
       ? = not tracked
       I = ignored
         = origin of the previous file (with --copies)
 
     .. container:: verbose
 
       The -t/--terse option abbreviates the output by showing directory name
       if all the files in it share the same status. The option expects a value
       which can be a string formed by using 'm', 'a', 'r', 'd', 'u', 'i', 'c'
       where, 'm' stands for 'modified', 'a' for 'added', 'r' for 'removed',
       'd' for 'deleted', 'u' for 'unknown', 'i' for 'ignored' and 'c' for clean.
 
       It terses the output of only those status which are passed. The ignored
       files are not considered while tersing until 'i' is there in --terse value
       or the --ignored option is used.
 
       --verbose option shows more context about the state of the repo
       like the repository is in unfinised merge, shelve, rebase state etc.
       You can have this behaviour turned on by default by following config:
 
       [commands]
       status.verbose = true
 
       You can also skip some states like bisect by adding following in
       configuration file.
 
       [commands]
       status.skipstates = bisect
 
       Examples:
 
       - show changes in the working directory relative to a
         changeset::

     Tags are used to name particular revisions of the repository and are
     very useful to compare different revisions, to go back to significant
     earlier versions or to mark branch points as releases, etc. Changing
     an existing tag is normally disallowed; use -f/--force to override.
 
     If no revision is given, the parent of the working directory is
     used.
 
     To facilitate version control, distribution, and merging of tags,
     they are stored as a file named ".hgtags" which is managed similarly
     to other project files and can be hand-edited if necessary. This
     also means that tagging creates a new commit. The file
     ".hg/localtags" is used for local tags (not shared among
     repositories).
 
     Tag commits are usually made at the head of a branch. If the parent
     of the working directory is not a branch head, :hg:`tag` aborts; use
     -f/--force to force the tag commit to be based on a non-head
     changeset.
 
     See :hg:`help dates` for a list of formats valid for -d/--date.
 
     Since tag names have priority over branch names during revision
     lookup, using an existing branch name as a tag name is discouraged.

mercurial/help/internals/wireprotocol.txt

@@ -1,921 +1,921 b''
 The Mercurial wire protocol is a request-response based protocol
 with multiple wire representations.
 
 Each request is modeled as a command name, a dictionary of arguments, and
 optional raw input. Command arguments and their types are intrinsic
 properties of commands. So is the response type of the command. This means
 clients can't always send arbitrary arguments to servers and servers can't
 return multiple response types.
 
 The protocol is synchronous and does not support multiplexing (concurrent
 commands).
 
 Transport Protocols
 ===================
 
 HTTP Transport
 --------------
 
 Commands are issued as HTTP/1.0 or HTTP/1.1 requests. Commands are
 sent to the base URL of the repository with the command name sent in
 the ``cmd`` query string parameter. e.g.
 ``https://example.com/repo?cmd=capabilities``. The HTTP method is ``GET``
 or ``POST`` depending on the command and whether there is a request
 body.
 
 Command arguments can be sent multiple ways.
 
 The simplest is part of the URL query string using ``x-www-form-urlencoded``
 encoding (see Python's ``urllib.urlencode()``. However, many servers impose
 length limitations on the URL. So this mechanism is typically only used if
 the server doesn't support other mechanisms.
 
 If the server supports the ``httpheader`` capability, command arguments can
 be sent in HTTP request headers named ``X-HgArg-<N>`` where ``<N>`` is an
 integer starting at 1. A ``x-www-form-urlencoded`` representation of the
 arguments is obtained. This full string is then split into chunks and sent
 in numbered ``X-HgArg-<N>`` headers. The maximum length of each HTTP header
 is defined by the server in the ``httpheader`` capability value, which defaults
 to ``1024``. The server reassembles the encoded arguments string by
 concatenating the ``X-HgArg-<N>`` headers then URL decodes them into a
 dictionary.
 
 The list of ``X-HgArg-<N>`` headers should be added to the ``Vary`` request
 header to instruct caches to take these headers into consideration when caching
 requests.
 
 If the server supports the ``httppostargs`` capability, the client
 may send command arguments in the HTTP request body as part of an
 HTTP POST request. The command arguments will be URL encoded just like
 they would for sending them via HTTP headers. However, no splitting is
 performed: the raw arguments are included in the HTTP request body.
 
 The client sends a ``X-HgArgs-Post`` header with the string length of the
 encoded arguments data. Additional data may be included in the HTTP
 request body immediately following the argument data. The offset of the
 non-argument data is defined by the ``X-HgArgs-Post`` header. The
 ``X-HgArgs-Post`` header is not required if there is no argument data.
 
 Additional command data can be sent as part of the HTTP request body. The
 default ``Content-Type`` when sending data is ``application/mercurial-0.1``.
 A ``Content-Length`` header is currently always sent.
 
 Example HTTP requests::
 
     GET /repo?cmd=capabilities
     X-HgArg-1: foo=bar&baz=hello%20world
 
 The request media type should be chosen based on server support. If the
 ``httpmediatype`` server capability is present, the client should send
 the newest mutually supported media type. If this capability is absent,
 the client must assume the server only supports the
 ``application/mercurial-0.1`` media type.
 
 The ``Content-Type`` HTTP response header identifies the response as coming
 from Mercurial and can also be used to signal an error has occurred.
 
 The ``application/mercurial-*`` media types indicate a generic Mercurial
 data type.
 
 The ``application/mercurial-0.1`` media type is raw Mercurial data. It is the
 predecessor of the format below.
 
 The ``application/mercurial-0.2`` media type is compression framed Mercurial
 data. The first byte of the payload indicates the length of the compression
 format identifier that follows. Next are N bytes indicating the compression
 format. e.g. ``zlib``. The remaining bytes are compressed according to that
 compression format. The decompressed data behaves the same as with
 ``application/mercurial-0.1``.
 
 The ``application/hg-error`` media type indicates a generic error occurred.
 The content of the HTTP response body typically holds text describing the
 error.
 
 The ``application/hg-changegroup`` media type indicates a changegroup response
 type.
 
 Clients also accept the ``text/plain`` media type. All other media
 types should cause the client to error.
 
 Behavior of media types is further described in the ``Content Negotiation``
 section below.
 
 Clients should issue a ``User-Agent`` request header that identifies the client.
 The server should not use the ``User-Agent`` for feature detection.
 
 A command returning a ``string`` response issues a
 ``application/mercurial-0.*`` media type and the HTTP response body contains
 the raw string value (after compression decoding, if used). A
 ``Content-Length`` header is typically issued, but not required.
 
 A command returning a ``stream`` response issues a
 ``application/mercurial-0.*`` media type and the HTTP response is typically
 using *chunked transfer* (``Transfer-Encoding: chunked``).
 
 SSH Transport
 =============
 
 The SSH transport is a custom text-based protocol suitable for use over any
 bi-directional stream transport. It is most commonly used with SSH.
 
 A SSH transport server can be started with ``hg serve --stdio``. The stdin,
 stderr, and stdout file descriptors of the started process are used to exchange
 data. When Mercurial connects to a remote server over SSH, it actually starts
 a ``hg serve --stdio`` process on the remote server.
 
 Commands are issued by sending the command name followed by a trailing newline
 ``\n`` to the server. e.g. ``capabilities\n``.
 
 Command arguments are sent in the following format::
 
     <argument> <length>\n<value>
 
 That is, the argument string name followed by a space followed by the
 integer length of the value (expressed as a string) followed by a newline
 (``\n``) followed by the raw argument value.
 
 Dictionary arguments are encoded differently::
 
     <argument> <# elements>\n
     <key1> <length1>\n<value1>
     <key2> <length2>\n<value2>
     ...
 
 Non-argument data is sent immediately after the final argument value. It is
 encoded in chunks::
 
     <length>\n<data>
 
 Each command declares a list of supported arguments and their types. If a
 client sends an unknown argument to the server, the server should abort
 immediately. The special argument ``*`` in a command's definition indicates
 that all argument names are allowed.
 
 The definition of supported arguments and types is initially made when a
 new command is implemented. The client and server must initially independently
 agree on the arguments and their types. This initial set of arguments can be
 supplemented through the presence of *capabilities* advertised by the server.
 
 Each command has a defined expected response type.
 
 A ``string`` response type is a length framed value. The response consists of
 the string encoded integer length of a value followed by a newline (``\n``)
 followed by the value. Empty values are allowed (and are represented as
 ``0\n``).
 
 A ``stream`` response type consists of raw bytes of data. There is no framing.
 
 A generic error response type is also supported. It consists of a an error
 message written to ``stderr`` followed by ``\n-\n``. In addition, ``\n`` is
 written to ``stdout``.
 
 If the server receives an unknown command, it will send an empty ``string``
 response.
 
 The server terminates if it receives an empty command (a ``\n`` character).
 
 Capabilities
 ============
 
 Servers advertise supported wire protocol features. This allows clients to
 probe for server features before blindly calling a command or passing a
 specific argument.
 
 The server's features are exposed via a *capabilities* string. This is a
 space-delimited string of tokens/features. Some features are single words
 like ``lookup`` or ``batch``. Others are complicated key-value pairs
 advertising sub-features. e.g. ``httpheader=2048``. When complex, non-word
 values are used, each feature name can define its own encoding of sub-values.
 Comma-delimited and ``x-www-form-urlencoded`` values are common.
 
 The following document capabilities defined by the canonical Mercurial server
 implementation.
 
 batch
 -----
 
 Whether the server supports the ``batch`` command.
 
 This capability/command was introduced in Mercurial 1.9 (released July 2011).
 
 branchmap
 ---------
 
 Whether the server supports the ``branchmap`` command.
 
 This capability/command was introduced in Mercurial 1.3 (released July 2009).
 
 bundle2-exp
 -----------
 
 Precursor to ``bundle2`` capability that was used before bundle2 was a
 stable feature.
 
 This capability was introduced in Mercurial 3.0 behind an experimental
 flag. This capability should not be observed in the wild.
 
 bundle2
 -------
 
 Indicates whether the server supports the ``bundle2`` data exchange format.
 
 The value of the capability is a URL quoted, newline (``\n``) delimited
 list of keys or key-value pairs.
 
 A key is simply a URL encoded string.
 
 A key-value pair is a URL encoded key separated from a URL encoded value by
 an ``=``. If the value is a list, elements are delimited by a ``,`` after
 URL encoding.
 
 For example, say we have the values::
 
   {'HG20': [], 'changegroup': ['01', '02'], 'digests': ['sha1', 'sha512']}
 
 We would first construct a string::
 
   HG20\nchangegroup=01,02\ndigests=sha1,sha512
 
 We would then URL quote this string::
 
   HG20%0Achangegroup%3D01%2C02%0Adigests%3Dsha1%2Csha512
 
 This capability was introduced in Mercurial 3.4 (released May 2015).
 
 changegroupsubset
 -----------------
 
 Whether the server supports the ``changegroupsubset`` command.
 
 This capability was introduced in Mercurial 0.9.2 (released December
 2006).
 
 This capability was introduced at the same time as the ``lookup``
 capability/command.
 
 compression
 -----------
 
 Declares support for negotiating compression formats.
 
 Presence of this capability indicates the server supports dynamic selection
 of compression formats based on the client request.
 
 Servers advertising this capability are required to support the
 ``application/mercurial-0.2`` media type in response to commands returning
 streams. Servers may support this media type on any command.
 
 The value of the capability is a comma-delimited list of strings declaring
 supported compression formats. The order of the compression formats is in
 server-preferred order, most preferred first.
 
 The identifiers used by the official Mercurial distribution are:
 
 bzip2
    bzip2
 none
    uncompressed / raw data
 zlib
    zlib (no gzip header)
 zstd
    zstd
 
 This capability was introduced in Mercurial 4.1 (released February 2017).
 
 getbundle
 ---------
 
 Whether the server supports the ``getbundle`` command.
 
 This capability was introduced in Mercurial 1.9 (released July 2011).
 
 httpheader
 ----------
 
 Whether the server supports receiving command arguments via HTTP request
 headers.
 
 The value of the capability is an integer describing the max header
 length that clients should send. Clients should ignore any content after a
 comma in the value, as this is reserved for future use.
 
 This capability was introduced in Mercurial 1.9 (released July 2011).
 
 httpmediatype
 -------------
 
 Indicates which HTTP media types (``Content-Type`` header) the server is
 capable of receiving and sending.
 
 The value of the capability is a comma-delimited list of strings identifying
 support for media type and transmission direction. The following strings may
 be present:
 
 0.1rx
    Indicates server support for receiving ``application/mercurial-0.1`` media
    types.
 
 0.1tx
    Indicates server support for sending ``application/mercurial-0.1`` media
    types.
 
 0.2rx
    Indicates server support for receiving ``application/mercurial-0.2`` media
    types.
 
 0.2tx
    Indicates server support for sending ``application/mercurial-0.2`` media
    types.
 
 minrx=X
    Minimum media type version the server is capable of receiving. Value is a
    string like ``0.2``.
 
    This capability can be used by servers to limit connections from legacy
    clients not using the latest supported media type. However, only clients
    with knowledge of this capability will know to consult this value. This
    capability is present so the client may issue a more user-friendly error
    when the server has locked out a legacy client.
 
 mintx=X
    Minimum media type version the server is capable of sending. Value is a
    string like ``0.1``.
 
 Servers advertising support for the ``application/mercurial-0.2`` media type
 should also advertise the ``compression`` capability.
 
 This capability was introduced in Mercurial 4.1 (released February 2017).
 
 httppostargs
 ------------
 
 **Experimental**
 
 Indicates that the server supports and prefers clients send command arguments
 via a HTTP POST request as part of the request body.
 
 This capability was introduced in Mercurial 3.8 (released May 2016).
 
 known
 -----
 
 Whether the server supports the ``known`` command.
 
 This capability/command was introduced in Mercurial 1.9 (released July 2011).
 
 lookup
 ------
 
 Whether the server supports the ``lookup`` command.
 
 This capability was introduced in Mercurial 0.9.2 (released December
 2006).
 
 This capability was introduced at the same time as the ``changegroupsubset``
 capability/command.
 
 pushkey
 -------
 
 Whether the server supports the ``pushkey`` and ``listkeys`` commands.
 
 This capability was introduced in Mercurial 1.6 (released July 2010).
 
 standardbundle
 --------------
 
 **Unsupported**
 
 This capability was introduced during the Mercurial 0.9.2 development cycle in
 2006. It was never present in a release, as it was replaced by the ``unbundle``
 capability. This capability should not be encountered in the wild.
 
 stream-preferred
 ----------------
 
 If present the server prefers that clients clone using the streaming clone
-protocol (``hg clone --uncompressed``) rather than the standard
+protocol (``hg clone --stream``) rather than the standard
 changegroup/bundle based protocol.
 
 This capability was introduced in Mercurial 2.2 (released May 2012).
 
 streamreqs
 ----------
 
 Indicates whether the server supports *streaming clones* and the *requirements*
 that clients must support to receive it.
 
 If present, the server supports the ``stream_out`` command, which transmits
 raw revlogs from the repository instead of changegroups. This provides a faster
 cloning mechanism at the expense of more bandwidth used.
 
 The value of this capability is a comma-delimited list of repo format
 *requirements*. These are requirements that impact the reading of data in
 the ``.hg/store`` directory. An example value is
 ``streamreqs=generaldelta,revlogv1`` indicating the server repo requires
 the ``revlogv1`` and ``generaldelta`` requirements.
 
 If the only format requirement is ``revlogv1``, the server may expose the
 ``stream`` capability instead of the ``streamreqs`` capability.
 
 This capability was introduced in Mercurial 1.7 (released November 2010).
 
 stream
 ------
 
 Whether the server supports *streaming clones* from ``revlogv1`` repos.
 
 If present, the server supports the ``stream_out`` command, which transmits
 raw revlogs from the repository instead of changegroups. This provides a faster
 cloning mechanism at the expense of more bandwidth used.
 
 This capability was introduced in Mercurial 0.9.1 (released July 2006).
 
 When initially introduced, the value of the capability was the numeric
 revlog revision. e.g. ``stream=1``. This indicates the changegroup is using
 ``revlogv1``. This simple integer value wasn't powerful enough, so the
 ``streamreqs`` capability was invented to handle cases where the repo
 requirements have more than just ``revlogv1``. Newer servers omit the
 ``=1`` since it was the only value supported and the value of ``1`` can
 be implied by clients.
 
 unbundlehash
 ------------
 
 Whether the ``unbundle`` commands supports receiving a hash of all the
 heads instead of a list.
 
 For more, see the documentation for the ``unbundle`` command.
 
 This capability was introduced in Mercurial 1.9 (released July 2011).
 
 unbundle
 --------
 
 Whether the server supports pushing via the ``unbundle`` command.
 
 This capability/command has been present since Mercurial 0.9.1 (released
 July 2006).
 
 Mercurial 0.9.2 (released December 2006) added values to the capability
 indicating which bundle types the server supports receiving. This value is a
 comma-delimited list. e.g. ``HG10GZ,HG10BZ,HG10UN``. The order of values
 reflects the priority/preference of that type, where the first value is the
 most preferred type.
 
 Handshake Protocol
 ==================
 
 While not explicitly required, it is common for clients to perform a
 *handshake* when connecting to a server. The handshake accomplishes 2 things:
 
 * Obtaining capabilities and other server features
 * Flushing extra server output (e.g. SSH servers may print extra text
   when connecting that may confuse the wire protocol)
 
 This isn't a traditional *handshake* as far as network protocols go because
 there is no persistent state as a result of the handshake: the handshake is
 simply the issuing of commands and commands are stateless.
 
 The canonical clients perform a capabilities lookup at connection establishment
 time. This is because clients must assume a server only supports the features
 of the original Mercurial server implementation until proven otherwise (from
 advertised capabilities). Nearly every server running today supports features
 that weren't present in the original Mercurial server implementation. Rather
 than wait for a client to perform functionality that needs to consult
 capabilities, it issues the lookup at connection start to avoid any delay later.
 
 For HTTP servers, the client sends a ``capabilities`` command request as
 soon as the connection is established. The server responds with a capabilities
 string, which the client parses.
 
 For SSH servers, the client sends the ``hello`` command (no arguments)
 and a ``between`` command with the ``pairs`` argument having the value
 ``0000000000000000000000000000000000000000-0000000000000000000000000000000000000000``.
 
 The ``between`` command has been supported since the original Mercurial
 server. Requesting the empty range will return a ``\n`` string response,
 which will be encoded as ``1\n\n`` (value length of ``1`` followed by a newline
 followed by the value, which happens to  be a newline).
 
 The ``hello`` command was later introduced. Servers supporting it will issue
 a response to that command before sending the ``1\n\n`` response to the
 ``between`` command. Servers not supporting ``hello`` will send an empty
 response (``0\n``).
 
 In addition to the expected output from the ``hello`` and ``between`` commands,
 servers may also send other output, such as *message of the day (MOTD)*
 announcements. Clients assume servers will send this output before the
 Mercurial server replies to the client-issued commands. So any server output
 not conforming to the expected command responses is assumed to be not related
 to Mercurial and can be ignored.
 
 Content Negotiation
 ===================
 
 The wire protocol has some mechanisms to help peers determine what content
 types and encoding the other side will accept. Historically, these mechanisms
 have been built into commands themselves because most commands only send a
 well-defined response type and only certain commands needed to support
 functionality like compression.
 
 Currently, only the HTTP transport supports content negotiation at the protocol
 layer.
 
 HTTP requests advertise supported response formats via the ``X-HgProto-<N>``
 request header, where ``<N>`` is an integer starting at 1 allowing the logical
 value to span multiple headers. This value consists of a list of
 space-delimited parameters. Each parameter denotes a feature or capability.
 
 The following parameters are defined:
 
 0.1
    Indicates the client supports receiving ``application/mercurial-0.1``
    responses.
 
 0.2
    Indicates the client supports receiving ``application/mercurial-0.2``
    responses.
 
 comp
    Indicates compression formats the client can decode. Value is a list of
    comma delimited strings identifying compression formats ordered from
    most preferential to least preferential. e.g. ``comp=zstd,zlib,none``.
 
    This parameter does not have an effect if only the ``0.1`` parameter
    is defined, as support for ``application/mercurial-0.2`` or greater is
    required to use arbitrary compression formats.
 
    If this parameter is not advertised, the server interprets this as
    equivalent to ``zlib,none``.
 
 Clients may choose to only send this header if the ``httpmediatype``
 server capability is present, as currently all server-side features
 consulting this header require the client to opt in to new protocol features
 advertised via the ``httpmediatype`` capability.
 
 A server that doesn't receive an ``X-HgProto-<N>`` header should infer a
 value of ``0.1``. This is compatible with legacy clients.
 
 A server receiving a request indicating support for multiple media type
 versions may respond with any of the supported media types. Not all servers
 may support all media types on all commands.
 
 Commands
 ========
 
 This section contains a list of all wire protocol commands implemented by
 the canonical Mercurial server.
 
 batch
 -----
 
 Issue multiple commands while sending a single command request. The purpose
 of this command is to allow a client to issue multiple commands while avoiding
 multiple round trips to the server therefore enabling commands to complete
 quicker.
 
 The command accepts a ``cmds`` argument that contains a list of commands to
 execute.
 
 The value of ``cmds`` is a ``;`` delimited list of strings. Each string has the
 form ``<command> <arguments>``. That is, the command name followed by a space
 followed by an argument string.
 
 The argument string is a ``,`` delimited list of ``<key>=<value>`` values
 corresponding to command arguments. Both the argument name and value are
 escaped using a special substitution map::
 
    : -> :c
    , -> :o
    ; -> :s
    = -> :e
 
 The response type for this command is ``string``. The value contains a
 ``;`` delimited list of responses for each requested command. Each value
 in this list is escaped using the same substitution map used for arguments.
 
 If an error occurs, the generic error response may be sent.
 
 between
 -------
 
 (Legacy command used for discovery in old clients)
 
 Obtain nodes between pairs of nodes.
 
 The ``pairs`` arguments contains a space-delimited list of ``-`` delimited
 hex node pairs. e.g.::
 
    a072279d3f7fd3a4aa7ffa1a5af8efc573e1c896-6dc58916e7c070f678682bfe404d2e2d68291a18
 
 Return type is a ``string``. Value consists of lines corresponding to each
 requested range. Each line contains a space-delimited list of hex nodes.
 A newline ``\n`` terminates each line, including the last one.
 
 branchmap
 ---------
 
 Obtain heads in named branches.
 
 Accepts no arguments. Return type is a ``string``.
 
 Return value contains lines with URL encoded branch names followed by a space
 followed by a space-delimited list of hex nodes of heads on that branch.
 e.g.::
 
     default a072279d3f7fd3a4aa7ffa1a5af8efc573e1c896 6dc58916e7c070f678682bfe404d2e2d68291a18
     stable baae3bf31522f41dd5e6d7377d0edd8d1cf3fccc
 
 There is no trailing newline.
 
 branches
 --------
 
 (Legacy command used for discovery in old clients. Clients with ``getbundle``
 use the ``known`` and ``heads`` commands instead.)
 
 Obtain ancestor changesets of specific nodes back to a branch point.
 
 Despite the name, this command has nothing to do with Mercurial named branches.
 Instead, it is related to DAG branches.
 
 The command accepts a ``nodes`` argument, which is a string of space-delimited
 hex nodes.
 
 For each node requested, the server will find the first ancestor node that is
 a DAG root or is a merge.
 
 Return type is a ``string``. Return value contains lines with result data for
 each requested node. Each line contains space-delimited nodes followed by a
 newline (``\n``). The 4 nodes reported on each line correspond to the requested
 node, the ancestor node found, and its 2 parent nodes (which may be the null
 node).
 
 capabilities
 ------------
 
 Obtain the capabilities string for the repo.
 
 Unlike the ``hello`` command, the capabilities string is not prefixed.
 There is no trailing newline.
 
 This command does not accept any arguments. Return type is a ``string``.
 
 changegroup
 -----------
 
 (Legacy command: use ``getbundle`` instead)
 
 Obtain a changegroup version 1 with data for changesets that are
 descendants of client-specified changesets.
 
 The ``roots`` arguments contains a list of space-delimited hex nodes.
 
 The server responds with a changegroup version 1 containing all
 changesets between the requested root/base nodes and the repo's head nodes
 at the time of the request.
 
 The return type is a ``stream``.
 
 changegroupsubset
 -----------------
 
 (Legacy command: use ``getbundle`` instead)
 
 Obtain a changegroup version 1 with data for changesetsets between
 client specified base and head nodes.
 
 The ``bases`` argument contains a list of space-delimited hex nodes.
 The ``heads`` argument contains a list of space-delimited hex nodes.
 
 The server responds with a changegroup version 1 containing all
 changesets between the requested base and head nodes at the time of the
 request.
 
 The return type is a ``stream``.
 
 clonebundles
 ------------
 
 Obtains a manifest of bundle URLs available to seed clones.
 
 Each returned line contains a URL followed by metadata. See the
 documentation in the ``clonebundles`` extension for more.
 
 The return type is a ``string``.
 
 getbundle
 ---------
 
 Obtain a bundle containing repository data.
 
 This command accepts the following arguments:
 
 heads
    List of space-delimited hex nodes of heads to retrieve.
 common
    List of space-delimited hex nodes that the client has in common with the
    server.
 obsmarkers
    Boolean indicating whether to include obsolescence markers as part
    of the response. Only works with bundle2.
 bundlecaps
    Comma-delimited set of strings defining client bundle capabilities.
 listkeys
    Comma-delimited list of strings of ``pushkey`` namespaces. For each
    namespace listed, a bundle2 part will be included with the content of
    that namespace.
 cg
    Boolean indicating whether changegroup data is requested.
 cbattempted
    Boolean indicating whether the client attempted to use the *clone bundles*
    feature before performing this request.
 
 The return type on success is a ``stream`` where the value is bundle.
 On the HTTP transport, the response is zlib compressed.
 
 If an error occurs, a generic error response can be sent.
 
 Unless the client sends a false value for the ``cg`` argument, the returned
 bundle contains a changegroup with the nodes between the specified ``common``
 and ``heads`` nodes. Depending on the command arguments, the type and content
 of the returned bundle can vary significantly.
 
 The default behavior is for the server to send a raw changegroup version
 ``01`` response.
 
 If the ``bundlecaps`` provided by the client contain a value beginning
 with ``HG2``, a bundle2 will be returned. The bundle2 data may contain
 additional repository data, such as ``pushkey`` namespace values.
 
 heads
 -----
 
 Returns a list of space-delimited hex nodes of repository heads followed
 by a newline. e.g.
 ``a9eeb3adc7ddb5006c088e9eda61791c777cbf7c 31f91a3da534dc849f0d6bfc00a395a97cf218a1\n``
 
 This command does not accept any arguments. The return type is a ``string``.
 
 hello
 -----
 
 Returns lines describing interesting things about the server in an RFC-822
 like format.
 
 Currently, the only line defines the server capabilities. It has the form::
 
     capabilities: <value>
 
 See above for more about the capabilities string.
 
 SSH clients typically issue this command as soon as a connection is
 established.
 
 This command does not accept any arguments. The return type is a ``string``.
 
 listkeys
 --------
 
 List values in a specified ``pushkey`` namespace.
 
 The ``namespace`` argument defines the pushkey namespace to operate on.
 
 The return type is a ``string``. The value is an encoded dictionary of keys.
 
 Key-value pairs are delimited by newlines (``\n``). Within each line, keys and
 values are separated by a tab (``\t``). Keys and values are both strings.
 
 lookup
 ------
 
 Try to resolve a value to a known repository revision.
 
 The ``key`` argument is converted from bytes to an
 ``encoding.localstr`` instance then passed into
 ``localrepository.__getitem__`` in an attempt to resolve it.
 
 The return type is a ``string``.
 
 Upon successful resolution, returns ``1 <hex node>\n``. On failure,
 returns ``0 <error string>\n``. e.g.::
 
    1 273ce12ad8f155317b2c078ec75a4eba507f1fba\n
 
    0 unknown revision 'foo'\n
 
 known
 -----
 
 Determine whether multiple nodes are known.
 
 The ``nodes`` argument is a list of space-delimited hex nodes to check
 for existence.
 
 The return type is ``string``.
 
 Returns a string consisting of ``0``s and ``1``s indicating whether nodes
 are known. If the Nth node specified in the ``nodes`` argument is known,
 a ``1`` will be returned at byte offset N. If the node isn't known, ``0``
 will be present at byte offset N.
 
 There is no trailing newline.
 
 pushkey
 -------
 
 Set a value using the ``pushkey`` protocol.
 
 Accepts arguments ``namespace``, ``key``, ``old``, and ``new``, which
 correspond to the pushkey namespace to operate on, the key within that
 namespace to change, the old value (which may be empty), and the new value.
 All arguments are string types.
 
 The return type is a ``string``. The value depends on the transport protocol.
 
 The SSH transport sends a string encoded integer followed by a newline
 (``\n``) which indicates operation result. The server may send additional
 output on the ``stderr`` stream that should be displayed to the user.
 
 The HTTP transport sends a string encoded integer followed by a newline
 followed by additional server output that should be displayed to the user.
 This may include output from hooks, etc.
 
 The integer result varies by namespace. ``0`` means an error has occurred
 and there should be additional output to display to the user.
 
 stream_out
 ----------
 
 Obtain *streaming clone* data.
 
 The return type is either a ``string`` or a ``stream``, depending on
 whether the request was fulfilled properly.
 
 A return value of ``1\n`` indicates the server is not configured to serve
 this data. If this is seen by the client, they may not have verified the
 ``stream`` capability is set before making the request.
 
 A return value of ``2\n`` indicates the server was unable to lock the
 repository to generate data.
 
 All other responses are a ``stream`` of bytes. The first line of this data
 contains 2 space-delimited integers corresponding to the path count and
 payload size, respectively::
 
     <path count> <payload size>\n
 
 The ``<payload size>`` is the total size of path data: it does not include
 the size of the per-path header lines.
 
 Following that header are ``<path count>`` entries. Each entry consists of a
 line with metadata followed by raw revlog data. The line consists of::
 
     <store path>\0<size>\n
 
 The ``<store path>`` is the encoded store path of the data that follows.
 ``<size>`` is the amount of data for this store path/revlog that follows the
 newline.
 
 There is no trailer to indicate end of data. Instead, the client should stop
 reading after ``<path count>`` entries are consumed.
 
 unbundle
 --------
 
 Send a bundle containing data (usually changegroup data) to the server.
 
 Accepts the argument ``heads``, which is a space-delimited list of hex nodes
 corresponding to server repository heads observed by the client. This is used
 to detect race conditions and abort push operations before a server performs
 too much work or a client transfers too much data.
 
 The request payload consists of a bundle to be applied to the repository,
 similarly to as if :hg:`unbundle` were called.
 
 In most scenarios, a special ``push response`` type is returned. This type
 contains an integer describing the change in heads as a result of the
 operation. A value of ``0`` indicates nothing changed. ``1`` means the number
 of heads remained the same. Values ``2`` and larger indicate the number of
 added heads minus 1. e.g. ``3`` means 2 heads were added. Negative values
 indicate the number of fewer heads, also off by 1. e.g. ``-2`` means there
 is 1 fewer head.
 
 The encoding of the ``push response`` type varies by transport.
 
 For the SSH transport, this type is composed of 2 ``string`` responses: an
 empty response (``0\n``) followed by the integer result value. e.g.
 ``1\n2``. So the full response might be ``0\n1\n2``.
 
 For the HTTP transport, the response is a ``string`` type composed of an
 integer result value followed by a newline (``\n``) followed by string
 content holding server output that should be displayed on the client (output
 hooks, etc).
 
 In some cases, the server may respond with a ``bundle2`` bundle. In this
 case, the response type is ``stream``. For the HTTP transport, the response
 is zlib compressed.
 
 The server may also respond with a generic error type, which contains a string
 indicating the failure.
