     the lock has been held, and the machine name where the process is
     running if it's not local.
 
     Locks protect the integrity of Mercurial's data, so should be
     treated with care. System crashes or other interruptions may cause
     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
     instance, on a shared filesystem). Removing locks may also be
     blocked by filesystem permissions.
 
     Setting a lock will prevent other commands from changing the data.
     The command will wait until an interruption (SIGINT, SIGTERM, ...) occurs.
     The set locks are removed when the command exits.

         FILE = MERGETOOL
 
     By default, all files known in the first parent context of the
     working directory are examined. Use file patterns and/or -I/-X
     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
     information, even with --debug. In such case, information above is
     useful to know why a merge tool is chosen.

     """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.

 It test multiple existing parts to test different feature of the container. You
 probably do not need to touch this test unless you change the binary encoding
 of the bundle2 format itself.

 Check whether size of generaldelta revlog is not bigger than its
 regular equivalent. Test would fail if generaldelta was naive
 implementation of parentdelta: third manifest revision would be fully

 Verify rev reordering doesnt create invalid bundles (issue4462)
 This requires a commit tree that when pulled will reorder manifest revs such
 that the second manifest to create a file rev will be ordered before the first
 manifest to create that file rev. We also need to do a partial pull to ensure
 reordering happens. At the end we verify the linkrev points at the earliest
 commit.

   hg shelve [OPTION]... [FILE]...
   
   save and set aside changes from the working directory
   
       Shelving takes files that "hg status" reports as not clean, saves the
       modifications to a bundle (a shelved change), and reverts the files so
       that their state in the working directory becomes clean.
   
       To restore these changes to the working directory, using "hg unshelve";
       this will work even if you switch to a different commit.
   
       When no files are specified, "hg shelve" saves all not-clean files. If
       specific files or directories are named, only changes to those files are
       shelved.
   
       In bare shelve (when no files are specified, without interactive, include
       and exclude option), shelving remembers information if the working
       directory was on newly created branch, in other words working directory
       was on different branch than its first parent. In this situation
       unshelving restores branch information to the working directory.
   
       Each shelved change has a name that makes it easier to find later. The
       name of a shelved change defaults to being based on the active bookmark,
       or if there is no active bookmark, the current named branch.  To specify a
       different name, use "--name".
   
       To see a list of existing shelved changes, use the "--list" option. For
       each shelved change, this will print its name, age, and description; use "
       --patch" or "--stat" for more details.
   
       To delete specific shelved changes, use "--delete". To delete all shelved
       changes, use "--cleanup".
   
   (use 'hg help -e shelve' to show help for the shelve extension)
   
   options ([+] can be repeated):
   
    -A --addremove           mark new/missing files as added/removed before
                             shelving
    -u --unknown             store unknown files in the shelve
       --cleanup             delete all shelved changes
       --date DATE           shelve with the specified commit date
    -d --delete              delete the named shelved change(s)
    -e --edit                invoke editor on commit messages
    -l --list                list current shelves
    -m --message TEXT        use text as shelve message
    -n --name NAME           use the given name for the shelved commit
    -p --patch               show patch
    -i --interactive         interactive mode, only works while creating a shelve
       --stat                output diffstat-style summary of changes
    -I --include PATTERN [+] include names matching the given patterns
    -X --exclude PATTERN [+] exclude names matching the given patterns

 "hg unshelve" at REV5 implies steps below:
 
 (1) commit changes in the working directory (REV6)
 (2) unbundle shelved revision (REV7)
 (3) rebase: merge REV7 into REV6 (REV6 => REV6, REV7)
 (4) rebase: commit merged revision (REV8)
 (5) rebase: update to REV6 (REV8 => REV6)
 (6) update to REV5 (REV6 => REV5)
 (7) abort transaction

 Shelve and unshelve unknown files. For the purposes of unshelve, a shelved
 unknown file is the same as a shelved added file, except that it will be in
 unknown state after unshelve if and only if it was either absent or unknown
 before the unshelve operation.
 
   $ hg init unknowns
   $ cd unknowns
 
 The simplest case is if I simply have an unknown file that I shelve and unshelve
 
   $ echo unknown > unknown
   $ hg status
   ? unknown
   $ hg shelve --unknown
   shelved as default
   0 files updated, 0 files merged, 1 files removed, 0 files unresolved
   $ hg status
   $ hg unshelve
   unshelving change 'default'
   $ hg status
   ? unknown
   $ rm unknown
 
 If I shelve, add the file, and unshelve, does it stay added?
 
   $ echo unknown > unknown
   $ hg shelve -u
   shelved as default
   0 files updated, 0 files merged, 1 files removed, 0 files unresolved
   $ hg status
   $ touch unknown
   $ hg add unknown
   $ hg status

   rebasing 1:098df96e7410 "(changes in empty repository)" (tip)
   merging unknown
   $ hg status
   A unknown
   $ hg forget unknown
   $ rm unknown
 
 And if I shelve, commit, then unshelve, does it become modified?
 
   $ echo unknown > unknown
   $ hg shelve -u
   shelved as default
   0 files updated, 0 files merged, 1 files removed, 0 files unresolved
   $ hg status

 We expects that non-bare shelve keeps newly created branch in
 working directory.

   $ hg branch
   new-branch
   $ hg status
   $ echo "d" >> d
   $ hg add d
   $ hg status

 We expect that bare-shelve will not keep branch in current working directory.
 
   $ hg shelve

   0 files updated, 0 files merged, 1 files removed, 0 files unresolved
   $ hg branch

 When i shelve commit on newly created branch i expect
 that after unshelve newly created branch will be preserved.
 
   $ hg init shelve_on_new_branch_simple

 When i shelve commit on newly created branch, make
 some changes, unshelve it and running into merge
 conflicts i expect that after fixing them and
 running unshelve --continue newly created branch
 will be preserved.

 # XXX need to test that the tag cache works when we strip an old head
 # and add a new one rooted off non-tip: i.e. node and rev of tip are the
 # same, but stuff has changed behind tip.
 
 Setup:
 
   $ hg init t
   $ cd t
   $ cacheexists
   no tag cache
   $ fnodescacheexists
   no fnodes cache
   $ hg id
   000000000000 tip
   $ cacheexists
   no tag cache
   $ fnodescacheexists
   no fnodes cache
   $ echo a > a
   $ hg add a
   $ hg commit -m "test"
   $ hg co
   0 files updated, 0 files merged, 0 files removed, 0 files unresolved
   $ hg identify
   acb14030fe0a tip
   $ hg identify -r 'wdir()'
   acb14030fe0a tip
   $ cacheexists
   tag cache exists
 No fnodes cache because .hgtags file doesn't exist
 (this is an implementation detail)
   $ fnodescacheexists
   no fnodes cache
 
 Try corrupting the cache
 
   $ printf 'a b' > .hg/cache/tags2-visible
   $ hg identify
   acb14030fe0a tip
   $ cacheexists
   tag cache exists
   $ fnodescacheexists
   no fnodes cache
   $ hg identify
   acb14030fe0a tip
 
 Create local tag with long name:
 
   $ T=`hg identify --debug --id`
   $ hg tag -l "This is a local tag with a really long name!"
   $ hg tags
   tip                                0:acb14030fe0a
   This is a local tag with a really long name!     0:acb14030fe0a
   $ rm .hg/localtags
 
 Create a tag behind hg's back:
 
   $ echo "$T first" > .hgtags
   $ cat .hgtags
   acb14030fe0a21b60322c440ad2d20cf7685a376 first
   $ hg add .hgtags
   $ hg commit -m "add tags"
   $ hg tags
   tip                                1:b9154636be93
   first                              0:acb14030fe0a
   $ hg identify
   b9154636be93 tip
 
 We should have a fnodes cache now that we have a real tag
 The cache should have an empty entry for rev 0 and a valid entry for rev 1.
 
 
   $ fnodescacheexists
   fnodes cache exists
   $ f --size --hexdump .hg/cache/hgtagsfnodes1
   .hg/cache/hgtagsfnodes1: size=48

 Repeat with cold tag cache:
 
   $ rm -f .hg/cache/tags2-visible .hg/cache/hgtagsfnodes1
   $ hg identify
   b9154636be93 tip
 
   $ fnodescacheexists

   $ rm -f .hg/cache/tags2-visible .hg/cache/hgtagsfnodes1
   $ chmod 555 .hg/cache
   $ hg identify

   $ chmod 755 .hg/cache
 
 (this block should be protected by no-fsmonitor, because "chmod 555 .hg"
 makes watchman fail at accessing to files under .hg)
 
   $ chmod 555 .hg

 Create a repository with tags data to test .hgtags fnodes transfer
 
   $ hg init tagsserver
   $ cd tagsserver
   $ touch foo
   $ hg -q commit -A -m initial
   $ hg tag -m 'tag 0.1' 0.1
   $ echo second > foo
   $ hg commit -m second
   $ hg tag -m 'tag 0.2' 0.2

 Cloning should pull down hgtags fnodes mappings and write the cache file
 
   $ hg clone --pull tagsserver tagsclient
   requesting all changes
   adding changesets
   adding manifests
   adding file changes
   added 4 changesets with 4 changes to 2 files
   new changesets 96ee1d7354c4:40f0358cb314
   updating to branch default
   2 files updated, 0 files merged, 0 files removed, 0 files unresolved
 
 Missing tags2* files means the cache wasn't written through the normal mechanism.
 
   $ ls tagsclient/.hg/cache
   branch2-base
   checkisexec (execbit !)
   checklink (symlink !)
   checklink-target (symlink !)
   hgtagsfnodes1
   rbc-names-v1
   rbc-revs-v1
 
 Cache should contain the head only, even though other nodes have tags data
 
   $ f --size --hexdump tagsclient/.hg/cache/hgtagsfnodes1
   tagsclient/.hg/cache/hgtagsfnodes1: size=96

 Running hg tags should produce tags2* file and not change cache
 
   $ hg -R tagsclient tags
