extensions: change magic "shipped with hg" string

I've caught multiple extensions in the wild lying about being
'internal', so it's time to move the goalposts on people. Goalpost
moving will continue until third party extensions stop trying to
defeat the system.

 '''synthesize structurally interesting change history
 
 This extension is useful for creating a repository with properties
 that are statistically similar to an existing repository. During
 analysis, a simple probability table is constructed from the history
 of an existing repository.  During synthesis, these properties are
 reconstructed.
 
 Properties that are analyzed and synthesized include the following:
 
 - Lines added or removed when an existing file is modified
 - Number and sizes of files added
 - Number of files removed
 - Line lengths
 - Topological distance to parent changeset(s)
 - Probability of a commit being a merge
 - Probability of a newly added file being added to a new directory
 - Interarrival time, and time zone, of commits
 - Number of files in each directory
 
 A few obvious properties that are not currently handled realistically:
 
 - Merges are treated as regular commits with two parents, which is not
   realistic
 - Modifications are not treated as operations on hunks of lines, but
   as insertions and deletions of randomly chosen single lines
 - Committer ID (always random)
 - Executability of files
 - Symlinks and binary files are ignored

 # acl.py - changeset access control for mercurial

 '''hooks for controlling repository access
 
 This hook makes it possible to allow or deny write access to given
 branches and paths of a repository when receiving incoming changesets
 via pretxnchangegroup and pretxncommit.
 
 The authorization is matched based on the local user name on the
 system where the hook runs, and not the committer of the original
 changeset (since the latter is merely informative).
 
 The acl hook is best used along with a restricted shell like hgsh,
 preventing authenticating users from doing anything other than pushing
 or pulling. The hook is not safe to use if users have interactive
 shell access, as they can then disable the hook. Nor is it safe if
 remote users share an account, because then there is no way to
 distinguish them.
 
 The order in which access checks are performed is:
 
 1) Deny  list for branches (section ``acl.deny.branches``)
 2) Allow list for branches (section ``acl.allow.branches``)
 3) Deny  list for paths    (section ``acl.deny``)
 4) Allow list for paths    (section ``acl.allow``)
 
 The allow and deny sections take key-value pairs.
 
 Branch-based Access Control
 ---------------------------
 
 Use the ``acl.deny.branches`` and ``acl.allow.branches`` sections to
 have branch-based access control. Keys in these sections can be
 either:
 
 - a branch name, or
 - an asterisk, to match any branch;
 
 The corresponding values can be either:
 
 - a comma-separated list containing users and groups, or
 - an asterisk, to match anyone;
 
 You can add the "!" prefix to a user or group name to invert the sense
 of the match.
 
 Path-based Access Control
 -------------------------
 
 Use the ``acl.deny`` and ``acl.allow`` sections to have path-based
 access control. Keys in these sections accept a subtree pattern (with
 a glob syntax by default). The corresponding values follow the same
 syntax as the other sections above.
 
 Groups
 ------
 
 Group names must be prefixed with an ``@`` symbol. Specifying a group
 name has the same effect as specifying all the users in that group.
 
 You can define group members in the ``acl.groups`` section.
 If a group name is not defined there, and Mercurial is running under
 a Unix-like system, the list of users will be taken from the OS.
 Otherwise, an exception will be raised.
 
 Example Configuration
 ---------------------
 
 ::
 
   [hooks]
 
   # Use this if you want to check access restrictions at commit time
   pretxncommit.acl = python:hgext.acl.hook
 
   # Use this if you want to check access restrictions for pull, push,
   # bundle and serve.
   pretxnchangegroup.acl = python:hgext.acl.hook
 
   [acl]
   # Allow or deny access for incoming changes only if their source is
   # listed here, let them pass otherwise. Source is "serve" for all
   # remote access (http or ssh), "push", "pull" or "bundle" when the
   # related commands are run locally.
   # Default: serve
   sources = serve
 
   [acl.deny.branches]
 
   # Everyone is denied to the frozen branch:
   frozen-branch = *
 
   # A bad user is denied on all branches:
   * = bad-user
 
   [acl.allow.branches]
 
   # A few users are allowed on branch-a:
   branch-a = user-1, user-2, user-3
 
   # Only one user is allowed on branch-b:
   branch-b = user-1
 
   # The super user is allowed on any branch:
   * = super-user
 
   # Everyone is allowed on branch-for-tests:
   branch-for-tests = *
 
   [acl.deny]
   # This list is checked first. If a match is found, acl.allow is not
   # checked. All users are granted access if acl.deny is not present.
   # Format for both lists: glob pattern = user, ..., @group, ...
 
   # To match everyone, use an asterisk for the user:
   # my/glob/pattern = *
 
   # user6 will not have write access to any file:
   ** = user6
 
   # Group "hg-denied" will not have write access to any file:
   ** = @hg-denied
 
   # Nobody will be able to change "DONT-TOUCH-THIS.txt", despite
   # everyone being able to change all other files. See below.
   src/main/resources/DONT-TOUCH-THIS.txt = *
 
   [acl.allow]
   # if acl.allow is not present, all users are allowed by default
   # empty acl.allow = no users allowed
 
   # User "doc_writer" has write access to any file under the "docs"
   # folder:
   docs/** = doc_writer
 
   # User "jack" and group "designers" have write access to any file
   # under the "images" folder:
   images/** = jack, @designers
 
   # Everyone (except for "user6" and "@hg-denied" - see acl.deny above)
   # will have write access to any file under the "resources" folder
   # (except for 1 file. See acl.deny):
   src/main/resources/** = *
 
   .hgtags = release_engineer
 
 Examples using the "!" prefix
 .............................
 
 Suppose there's a branch that only a given user (or group) should be able to
 push to, and you don't want to restrict access to any other branch that may
 be created.
 
 The "!" prefix allows you to prevent anyone except a given user or group to
 push changesets in a given branch or path.
 
 In the examples below, we will:
 1) Deny access to branch "ring" to anyone but user "gollum"
 2) Deny access to branch "lake" to anyone but members of the group "hobbit"
 3) Deny access to a file to anyone but user "gollum"
 
 ::
 
   [acl.allow.branches]
   # Empty
 
   [acl.deny.branches]
 
   # 1) only 'gollum' can commit to branch 'ring';
   # 'gollum' and anyone else can still commit to any other branch.
   ring = !gollum
 
   # 2) only members of the group 'hobbit' can commit to branch 'lake';
   # 'hobbit' members and anyone else can still commit to any other branch.
   lake = !@hobbit
 
   # You can also deny access based on file paths:
 
   [acl.allow]
   # Empty
 
   [acl.deny]
   # 3) only 'gollum' can change the file below;
   # 'gollum' and anyone else can still change any other file.
   /misty/mountains/cave/ring = !gollum

 '''hooks for integrating with the Bugzilla bug tracker
 
 This hook extension adds comments on bugs in Bugzilla when changesets
 that refer to bugs by Bugzilla ID are seen. The comment is formatted using
 the Mercurial template mechanism.
 
 The bug references can optionally include an update for Bugzilla of the
 hours spent working on the bug. Bugs can also be marked fixed.
 
 Three basic modes of access to Bugzilla are provided:
 
 1. Access via the Bugzilla XMLRPC interface. Requires Bugzilla 3.4 or later.
 
 2. Check data via the Bugzilla XMLRPC interface and submit bug change
    via email to Bugzilla email interface. Requires Bugzilla 3.4 or later.
 
 3. Writing directly to the Bugzilla database. Only Bugzilla installations
    using MySQL are supported. Requires Python MySQLdb.
 
 Writing directly to the database is susceptible to schema changes, and
 relies on a Bugzilla contrib script to send out bug change
 notification emails. This script runs as the user running Mercurial,
 must be run on the host with the Bugzilla install, and requires
 permission to read Bugzilla configuration details and the necessary
 MySQL user and password to have full access rights to the Bugzilla
 database. For these reasons this access mode is now considered
 deprecated, and will not be updated for new Bugzilla versions going
 forward. Only adding comments is supported in this access mode.
 
 Access via XMLRPC needs a Bugzilla username and password to be specified
 in the configuration. Comments are added under that username. Since the
 configuration must be readable by all Mercurial users, it is recommended
 that the rights of that user are restricted in Bugzilla to the minimum
 necessary to add comments. Marking bugs fixed requires Bugzilla 4.0 and later.
 
 Access via XMLRPC/email uses XMLRPC to query Bugzilla, but sends
 email to the Bugzilla email interface to submit comments to bugs.
 The From: address in the email is set to the email address of the Mercurial
 user, so the comment appears to come from the Mercurial user. In the event
 that the Mercurial user email is not recognized by Bugzilla as a Bugzilla
 user, the email associated with the Bugzilla username used to log into
 Bugzilla is used instead as the source of the comment. Marking bugs fixed
 works on all supported Bugzilla versions.
 
 Configuration items common to all access modes:
 
 bugzilla.version
   The access type to use. Values recognized are:
 
   :``xmlrpc``:       Bugzilla XMLRPC interface.
   :``xmlrpc+email``: Bugzilla XMLRPC and email interfaces.
   :``3.0``:          MySQL access, Bugzilla 3.0 and later.
   :``2.18``:         MySQL access, Bugzilla 2.18 and up to but not
                      including 3.0.
   :``2.16``:         MySQL access, Bugzilla 2.16 and up to but not
                      including 2.18.
 
 bugzilla.regexp
   Regular expression to match bug IDs for update in changeset commit message.
   It must contain one "()" named group ``<ids>`` containing the bug
   IDs separated by non-digit characters. It may also contain
   a named group ``<hours>`` with a floating-point number giving the
   hours worked on the bug. If no named groups are present, the first
   "()" group is assumed to contain the bug IDs, and work time is not
   updated. The default expression matches ``Bug 1234``, ``Bug no. 1234``,
   ``Bug number 1234``, ``Bugs 1234,5678``, ``Bug 1234 and 5678`` and
   variations thereof, followed by an hours number prefixed by ``h`` or
   ``hours``, e.g. ``hours 1.5``. Matching is case insensitive.
 
 bugzilla.fixregexp
   Regular expression to match bug IDs for marking fixed in changeset
   commit message. This must contain a "()" named group ``<ids>` containing
   the bug IDs separated by non-digit characters. It may also contain
   a named group ``<hours>`` with a floating-point number giving the
   hours worked on the bug. If no named groups are present, the first
   "()" group is assumed to contain the bug IDs, and work time is not
   updated. The default expression matches ``Fixes 1234``, ``Fixes bug 1234``,
   ``Fixes bugs 1234,5678``, ``Fixes 1234 and 5678`` and
   variations thereof, followed by an hours number prefixed by ``h`` or
   ``hours``, e.g. ``hours 1.5``. Matching is case insensitive.
 
 bugzilla.fixstatus
   The status to set a bug to when marking fixed. Default ``RESOLVED``.
 
 bugzilla.fixresolution
   The resolution to set a bug to when marking fixed. Default ``FIXED``.
 
 bugzilla.style
   The style file to use when formatting comments.
 
 bugzilla.template
   Template to use when formatting comments. Overrides style if
   specified. In addition to the usual Mercurial keywords, the
   extension specifies:
 
   :``{bug}``:     The Bugzilla bug ID.
   :``{root}``:    The full pathname of the Mercurial repository.
   :``{webroot}``: Stripped pathname of the Mercurial repository.
   :``{hgweb}``:   Base URL for browsing Mercurial repositories.
 
   Default ``changeset {node|short} in repo {root} refers to bug
   {bug}.\\ndetails:\\n\\t{desc|tabindent}``
 
 bugzilla.strip
   The number of path separator characters to strip from the front of
   the Mercurial repository path (``{root}`` in templates) to produce
   ``{webroot}``. For example, a repository with ``{root}``
   ``/var/local/my-project`` with a strip of 2 gives a value for
   ``{webroot}`` of ``my-project``. Default 0.
 
 web.baseurl
   Base URL for browsing Mercurial repositories. Referenced from
   templates as ``{hgweb}``.
 
 Configuration items common to XMLRPC+email and MySQL access modes:
 
 bugzilla.usermap
   Path of file containing Mercurial committer email to Bugzilla user email
   mappings. If specified, the file should contain one mapping per
   line::
 
     committer = Bugzilla user
 
   See also the ``[usermap]`` section.
 
 The ``[usermap]`` section is used to specify mappings of Mercurial
 committer email to Bugzilla user email. See also ``bugzilla.usermap``.
 Contains entries of the form ``committer = Bugzilla user``.
 
 XMLRPC access mode configuration:
 
 bugzilla.bzurl
   The base URL for the Bugzilla installation.
   Default ``http://localhost/bugzilla``.
 
 bugzilla.user
   The username to use to log into Bugzilla via XMLRPC. Default
   ``bugs``.
 
 bugzilla.password
   The password for Bugzilla login.
 
 XMLRPC+email access mode uses the XMLRPC access mode configuration items,
 and also:
 
 bugzilla.bzemail
   The Bugzilla email address.
 
 In addition, the Mercurial email settings must be configured. See the
 documentation in hgrc(5), sections ``[email]`` and ``[smtp]``.
 
 MySQL access mode configuration:
 
 bugzilla.host
   Hostname of the MySQL server holding the Bugzilla database.
   Default ``localhost``.
 
 bugzilla.db
   Name of the Bugzilla database in MySQL. Default ``bugs``.
 
 bugzilla.user
   Username to use to access MySQL server. Default ``bugs``.
 
 bugzilla.password
   Password to use to access MySQL server.
 
 bugzilla.timeout
   Database connection timeout (seconds). Default 5.
 
 bugzilla.bzuser
   Fallback Bugzilla user name to record comments with, if changeset
   committer cannot be found as a Bugzilla user.
 
 bugzilla.bzdir
    Bugzilla install directory. Used by default notify. Default
    ``/var/www/html/bugzilla``.
 
 bugzilla.notify
   The command to run to get Bugzilla to send bug change notification
   emails. Substitutes from a map with 3 keys, ``bzdir``, ``id`` (bug
   id) and ``user`` (committer bugzilla email). Default depends on
   version; from 2.18 it is "cd %(bzdir)s && perl -T
   contrib/sendbugmail.pl %(id)s %(user)s".
 
 Activating the extension::
 
     [extensions]
     bugzilla =
 
     [hooks]
     # run bugzilla hook on every change pulled or pushed in here
     incoming.bugzilla = python:hgext.bugzilla.hook
 
 Example configurations:

 # This extension enables removal of file content at a given revision,
 # rewriting the data/metadata of successive revisions to preserve revision log
 # integrity.
 
 """erase file content at a given revision
 
 The censor command instructs Mercurial to erase all content of a file at a given
 revision *without updating the changeset hash.* This allows existing history to
 remain valid while preventing future clones/pulls from receiving the erased
 data.
 
 Typical uses for censor are due to security or legal requirements, including::
 
  * Passwords, private keys, cryptographic material
  * Licensed data/code/libraries for which the license has expired
  * Personally Identifiable Information or other private data
 
 Censored nodes can interrupt mercurial's typical operation whenever the excised
 data needs to be materialized. Some commands, like ``hg cat``/``hg revert``,
 simply fail when asked to produce censored data. Others, like ``hg verify`` and
 ``hg update``, must be capable of tolerating censored data to continue to
 function in a meaningful way. Such commands only tolerate censored file
 revisions if they are allowed by the "censor.policy=ignore" config option.

 """advertise pre-generated bundles to seed clones
 
 "clonebundles" is a server-side extension used to advertise the existence
 of pre-generated, externally hosted bundle files to clients that are
 cloning so that cloning can be faster, more reliable, and require less
 resources on the server.
 
 Cloning can be a CPU and I/O intensive operation on servers. Traditionally,
 the server, in response to a client's request to clone, dynamically generates
 a bundle containing the entire repository content and sends it to the client.
 There is no caching on the server and the server will have to redundantly
 generate the same outgoing bundle in response to each clone request. For
 servers with large repositories or with high clone volume, the load from
 clones can make scaling the server challenging and costly.
 
 This extension provides server operators the ability to offload potentially
 expensive clone load to an external service. Here's how it works.
 
 1. A server operator establishes a mechanism for making bundle files available
    on a hosting service where Mercurial clients can fetch them.
 2. A manifest file listing available bundle URLs and some optional metadata
    is added to the Mercurial repository on the server.
 3. A client initiates a clone against a clone bundles aware server.
 4. The client sees the server is advertising clone bundles and fetches the
    manifest listing available bundles.
 5. The client filters and sorts the available bundles based on what it
    supports and prefers.
 6. The client downloads and applies an available bundle from the
    server-specified URL.
 7. The client reconnects to the original server and performs the equivalent
    of :hg:`pull` to retrieve all repository data not in the bundle. (The
    repository could have been updated between when the bundle was created
    and when the client started the clone.)
 
 Instead of the server generating full repository bundles for every clone
 request, it generates full bundles once and they are subsequently reused to
 bootstrap new clones. The server may still transfer data at clone time.
 However, this is only data that has been added/changed since the bundle was
 created. For large, established repositories, this can reduce server load for
 clones to less than 1% of original.
 
 To work, this extension requires the following of server operators:
 
 * Generating bundle files of repository content (typically periodically,
   such as once per day).
 * A file server that clients have network access to and that Python knows
   how to talk to through its normal URL handling facility (typically an
   HTTP server).
 * A process for keeping the bundles manifest in sync with available bundle
   files.
 
 Strictly speaking, using a static file hosting server isn't required: a server
 operator could use a dynamic service for retrieving bundle data. However,
 static file hosting services are simple and scalable and should be sufficient
 for most needs.
 
 Bundle files can be generated with the :hg:`bundle` command. Typically
 :hg:`bundle --all` is used to produce a bundle of the entire repository.
 
 :hg:`debugcreatestreamclonebundle` can be used to produce a special
 *streaming clone bundle*. These are bundle files that are extremely efficient
 to produce and consume (read: fast). However, they are larger than
 traditional bundle formats and require that clients support the exact set
 of repository data store formats in use by the repository that created them.
 Typically, a newer server can serve data that is compatible with older clients.
 However, *streaming clone bundles* don't have this guarantee. **Server
 operators need to be aware that newer versions of Mercurial may produce
 streaming clone bundles incompatible with older Mercurial versions.**
 
 A server operator is responsible for creating a ``.hg/clonebundles.manifest``
 file containing the list of available bundle files suitable for seeding
 clones. If this file does not exist, the repository will not advertise the
 existence of clone bundles when clients connect.
 
 The manifest file contains a newline (\n) delimited list of entries.
 
 Each line in this file defines an available bundle. Lines have the format:
 
     <URL> [<key>=<value>[ <key>=<value>]]
 
 That is, a URL followed by an optional, space-delimited list of key=value
 pairs describing additional properties of this bundle. Both keys and values
 are URI encoded.
 
 Keys in UPPERCASE are reserved for use by Mercurial and are defined below.
 All non-uppercase keys can be used by site installations. An example use
 for custom properties is to use the *datacenter* attribute to define which
 data center a file is hosted in. Clients could then prefer a server in the
 data center closest to them.
 
 The following reserved keys are currently defined:
 
 BUNDLESPEC
    A "bundle specification" string that describes the type of the bundle.
 
    These are string values that are accepted by the "--type" argument of
    :hg:`bundle`.
 
    The values are parsed in strict mode, which means they must be of the
    "<compression>-<type>" form. See
    mercurial.exchange.parsebundlespec() for more details.
 
    :hg:`debugbundle --spec` can be used to print the bundle specification
    string for a bundle file. The output of this command can be used verbatim
    for the value of ``BUNDLESPEC`` (it is already escaped).
 
    Clients will automatically filter out specifications that are unknown or
    unsupported so they won't attempt to download something that likely won't
    apply.
 
    The actual value doesn't impact client behavior beyond filtering:
    clients will still sniff the bundle type from the header of downloaded
    files.
 
    **Use of this key is highly recommended**, as it allows clients to
    easily skip unsupported bundles. If this key is not defined, an old
    client may attempt to apply a bundle that it is incapable of reading.
 
 REQUIRESNI
    Whether Server Name Indication (SNI) is required to connect to the URL.
    SNI allows servers to use multiple certificates on the same IP. It is
    somewhat common in CDNs and other hosting providers. Older Python
    versions do not support SNI. Defining this attribute enables clients
    with older Python versions to filter this entry without experiencing
    an opaque SSL failure at connection time.
 
    If this is defined, it is important to advertise a non-SNI fallback
    URL or clients running old Python releases may not be able to clone
    with the clonebundles facility.
 
    Value should be "true".
 
 Manifests can contain multiple entries. Assuming metadata is defined, clients
 will filter entries from the manifest that they don't support. The remaining
 entries are optionally sorted by client preferences
 (``experimental.clonebundleprefers`` config option). The client then attempts
 to fetch the bundle at the first URL in the remaining list.
 
 **Errors when downloading a bundle will fail the entire clone operation:
 clients do not automatically fall back to a traditional clone.** The reason
 for this is that if a server is using clone bundles, it is probably doing so
 because the feature is necessary to help it scale. In other words, there
 is an assumption that clone load will be offloaded to another service and
 that the Mercurial server isn't responsible for serving this clone load.
 If that other service experiences issues and clients start mass falling back to
 the original Mercurial server, the added clone load could overwhelm the server
 due to unexpected load and effectively take it offline. Not having clients
 automatically fall back to cloning from the original server mitigates this
 scenario.
 
 Because there is no automatic Mercurial server fallback on failure of the
 bundle hosting service, it is important for server operators to view the bundle
 hosting service as an extension of the Mercurial server in terms of
 availability and service level agreements: if the bundle hosting service goes
 down, so does the ability for clients to clone. Note: clients will see a
 message informing them how to bypass the clone bundles facility when a failure
 occurs. So server operators should prepare for some people to follow these
 instructions when a failure occurs, thus driving more load to the original
 Mercurial server when the bundle hosting service fails.

 '''colorize output from some commands
 
 The color extension colorizes output from several Mercurial commands.
 For example, the diff command shows additions in green and deletions
 in red, while the status command shows modified files in magenta. Many
 other commands have analogous colors. It is possible to customize
 these colors.
 
 Effects
 -------
 
 Other effects in addition to color, like bold and underlined text, are
 also available. By default, the terminfo database is used to find the
 terminal codes used to change color and effect.  If terminfo is not
 available, then effects are rendered with the ECMA-48 SGR control
 function (aka ANSI escape codes).
 
 The available effects in terminfo mode are 'blink', 'bold', 'dim',
 'inverse', 'invisible', 'italic', 'standout', and 'underline'; in
 ECMA-48 mode, the options are 'bold', 'inverse', 'italic', and
 'underline'.  How each is rendered depends on the terminal emulator.
 Some may not be available for a given terminal type, and will be
 silently ignored.
 
 Labels
 ------
 
 Text receives color effects depending on the labels that it has. Many
 default Mercurial commands emit labelled text. You can also define
 your own labels in templates using the label function, see :hg:`help
 templates`. A single portion of text may have more than one label. In
 that case, effects given to the last label will override any other
 effects. This includes the special "none" effect, which nullifies
 other effects.
 
 Labels are normally invisible. In order to see these labels and their
 position in the text, use the global --color=debug option. The same
 anchor text may be associated to multiple labels, e.g.
 
   [log.changeset changeset.secret|changeset:   22611:6f0a53c8f587]
 
 The following are the default effects for some default labels. Default
 effects may be overridden from your configuration file::
 
   [color]
   status.modified = blue bold underline red_background
   status.added = green bold
   status.removed = red bold blue_background
   status.deleted = cyan bold underline
   status.unknown = magenta bold underline
   status.ignored = black bold
 
   # 'none' turns off all effects
   status.clean = none
   status.copied = none
 
   qseries.applied = blue bold underline
   qseries.unapplied = black bold
   qseries.missing = red bold
 
   diff.diffline = bold
   diff.extended = cyan bold
   diff.file_a = red bold
   diff.file_b = green bold
   diff.hunk = magenta
   diff.deleted = red
   diff.inserted = green
   diff.changed = white
   diff.tab =
   diff.trailingwhitespace = bold red_background
 
   # Blank so it inherits the style of the surrounding label
   changeset.public =
   changeset.draft =
   changeset.secret =
 
   resolve.unresolved = red bold
   resolve.resolved = green bold
 
   bookmarks.active = green
 
   branches.active = none
   branches.closed = black bold
   branches.current = green
   branches.inactive = none
 
   tags.normal = green
   tags.local = black bold
 
   rebase.rebased = blue
   rebase.remaining = red bold
 
   shelve.age = cyan
   shelve.newest = green bold
   shelve.name = blue bold
 
   histedit.remaining = red bold
 
 Custom colors
 -------------
 
 Because there are only eight standard colors, this module allows you
 to define color names for other color slots which might be available
 for your terminal type, assuming terminfo mode.  For instance::
 
   color.brightblue = 12
   color.pink = 207
   color.orange = 202
 
 to set 'brightblue' to color slot 12 (useful for 16 color terminals
 that have brighter colors defined in the upper eight) and, 'pink' and
 'orange' to colors in 256-color xterm's default color cube.  These
 defined colors may then be used as any of the pre-defined eight,
 including appending '_background' to set the background to that color.
 
 Modes
 -----
 
 By default, the color extension will use ANSI mode (or win32 mode on
 Windows) if it detects a terminal. To override auto mode (to enable
 terminfo mode, for example), set the following configuration option::
 
   [color]
   mode = terminfo
 
 Any value other than 'ansi', 'win32', 'terminfo', or 'auto' will
 disable color.
 
 Note that on some systems, terminfo mode may cause problems when using
 color with the pager extension and less -R. less with the -R option
 will only display ECMA-48 color codes, and terminfo mode may sometimes
 emit codes that less doesn't understand. You can work around this by
 either using ansi mode (or auto mode), or by using less -r (which will
 pass through all terminal control codes, not just color control
 codes).
 
 On some systems (such as MSYS in Windows), the terminal may support
 a different color mode than the pager (activated via the "pager"
 extension). It is possible to define separate modes depending on whether
 the pager is active::
 
   [color]
   mode = auto
   pagermode = ansi
 
 If ``pagermode`` is not defined, the ``mode`` will be used.

     Accepted source formats [identifiers]:
 
     - Mercurial [hg]
     - CVS [cvs]
     - Darcs [darcs]
     - git [git]
     - Subversion [svn]
     - Monotone [mtn]
     - GNU Arch [gnuarch]
     - Bazaar [bzr]
     - Perforce [p4]
 
     Accepted destination formats [identifiers]:
 
     - Mercurial [hg]
     - Subversion [svn] (history on branches is not preserved)
 
     If no revision is given, all revisions will be converted.
     Otherwise, convert will only import up to the named revision
     (given in a format understood by the source).
 
     If no destination directory name is specified, it defaults to the
     basename of the source with ``-hg`` appended. If the destination
     repository doesn't exist, it will be created.
 
     By default, all sources except Mercurial will use --branchsort.
     Mercurial uses --sourcesort to preserve original revision numbers
     order. Sort modes have the following effects:
 
     --branchsort  convert from parent to child revision when possible,
                   which means branches are usually converted one after
                   the other. It generates more compact repositories.
 
     --datesort    sort revisions by date. Converted repositories have
                   good-looking changelogs but are often an order of
                   magnitude larger than the same ones generated by
                   --branchsort.
 
     --sourcesort  try to preserve source revisions order, only
                   supported by Mercurial sources.
 
     --closesort   try to move closed revisions as close as possible
                   to parent branches, only supported by Mercurial
                   sources.
 
     If ``REVMAP`` isn't given, it will be put in a default location
     (``<dest>/.hg/shamap`` by default). The ``REVMAP`` is a simple
     text file that maps each source commit ID to the destination ID
     for that revision, like so::
 
       <source ID> <destination ID>
 
     If the file doesn't exist, it's automatically created. It's
     updated on each commit copied, so :hg:`convert` can be interrupted
     and can be run repeatedly to copy new commits.
 
     The authormap is a simple text file that maps each source commit
     author to a destination commit author. It is handy for source SCMs
     that use unix logins to identify authors (e.g.: CVS). One line per
     author mapping and the line format is::
 
       source author = destination author
 
     Empty lines and lines starting with a ``#`` are ignored.
 
     The filemap is a file that allows filtering and remapping of files
     and directories. Each line can contain one of the following
     directives::
 
       include path/to/file-or-dir
 
       exclude path/to/file-or-dir
 
       rename path/to/source path/to/destination
 
     Comment lines start with ``#``. A specified path matches if it
     equals the full relative name of a file or one of its parent
     directories. The ``include`` or ``exclude`` directive with the
     longest matching path applies, so line order does not matter.
 
     The ``include`` directive causes a file, or all files under a
     directory, to be included in the destination repository. The default
     if there are no ``include`` statements is to include everything.
     If there are any ``include`` statements, nothing else is included.
     The ``exclude`` directive causes files or directories to
     be omitted. The ``rename`` directive renames a file or directory if
     it is converted. To rename from a subdirectory into the root of
     the repository, use ``.`` as the path to rename to.
 
     ``--full`` will make sure the converted changesets contain exactly
     the right files with the right content. It will make a full
     conversion of all files, not just the ones that have
     changed. Files that already are correct will not be changed. This
     can be used to apply filemap changes when converting
     incrementally. This is currently only supported for Mercurial and
     Subversion.
 
     The splicemap is a file that allows insertion of synthetic
     history, letting you specify the parents of a revision. This is
     useful if you want to e.g. give a Subversion merge two parents, or
     graft two disconnected series of history together. Each entry
     contains a key, followed by a space, followed by one or two
     comma-separated values::
 
       key parent1, parent2
 
     The key is the revision ID in the source
     revision control system whose parents should be modified (same
     format as a key in .hg/shamap). The values are the revision IDs
     (in either the source or destination revision control system) that
     should be used as the new parents for that node. For example, if
     you have merged "release-1.0" into "trunk", then you should
     specify the revision on "trunk" as the first parent and the one on
     the "release-1.0" branch as the second.
 
     The branchmap is a file that allows you to rename a branch when it is
     being brought in from whatever external repository. When used in
     conjunction with a splicemap, it allows for a powerful combination
     to help fix even the most badly mismanaged repositories and turn them
     into nicely structured Mercurial repositories. The branchmap contains
     lines of the form::
 
       original_branch_name new_branch_name
 
     where "original_branch_name" is the name of the branch in the
     source repository, and "new_branch_name" is the name of the branch
     is the destination repository. No whitespace is allowed in the
     branch names. This can be used to (for instance) move code in one
     repository from "default" to a named branch.
 
     Mercurial Source
     ################
 
     The Mercurial source recognizes the following configuration
     options, which you can set on the command line with ``--config``:
 
     :convert.hg.ignoreerrors: ignore integrity errors when reading.
         Use it to fix Mercurial repositories with missing revlogs, by
         converting from and to Mercurial. Default is False.
 
     :convert.hg.saverev: store original revision ID in changeset
         (forces target IDs to change). It takes a boolean argument and
         defaults to False.
 
     :convert.hg.startrev: specify the initial Mercurial revision.
         The default is 0.
 
     :convert.hg.revs: revset specifying the source revisions to convert.
 
     CVS Source
     ##########
 
     CVS source will use a sandbox (i.e. a checked-out copy) from CVS
     to indicate the starting point of what will be converted. Direct
     access to the repository files is not needed, unless of course the
     repository is ``:local:``. The conversion uses the top level
     directory in the sandbox to find the CVS repository, and then uses
     CVS rlog commands to find files to convert. This means that unless
     a filemap is given, all files under the starting directory will be
     converted, and that any directory reorganization in the CVS
     sandbox is ignored.
 
     The following options can be used with ``--config``:
 
     :convert.cvsps.cache: Set to False to disable remote log caching,
         for testing and debugging purposes. Default is True.
 
     :convert.cvsps.fuzz: Specify the maximum time (in seconds) that is
         allowed between commits with identical user and log message in
         a single changeset. When very large files were checked in as
         part of a changeset then the default may not be long enough.
         The default is 60.
 
     :convert.cvsps.mergeto: Specify a regular expression to which
         commit log messages are matched. If a match occurs, then the
         conversion process will insert a dummy revision merging the
         branch on which this log message occurs to the branch
         indicated in the regex. Default is ``{{mergetobranch
         ([-\\w]+)}}``
 
     :convert.cvsps.mergefrom: Specify a regular expression to which
         commit log messages are matched. If a match occurs, then the
         conversion process will add the most recent revision on the
         branch indicated in the regex as the second parent of the
         changeset. Default is ``{{mergefrombranch ([-\\w]+)}}``
 
     :convert.localtimezone: use local time (as determined by the TZ
         environment variable) for changeset date/times. The default
         is False (use UTC).
 
     :hooks.cvslog: Specify a Python function to be called at the end of
         gathering the CVS log. The function is passed a list with the
         log entries, and can modify the entries in-place, or add or
         delete them.
 
     :hooks.cvschangesets: Specify a Python function to be called after
         the changesets are calculated from the CVS log. The
         function is passed a list with the changeset entries, and can
         modify the changesets in-place, or add or delete them.
 
     An additional "debugcvsps" Mercurial command allows the builtin
     changeset merging code to be run without doing a conversion. Its
     parameters and output are similar to that of cvsps 2.1. Please see
     the command help for more details.
 
     Subversion Source
     #################
 
     Subversion source detects classical trunk/branches/tags layouts.
     By default, the supplied ``svn://repo/path/`` source URL is
     converted as a single branch. If ``svn://repo/path/trunk`` exists
     it replaces the default branch. If ``svn://repo/path/branches``
     exists, its subdirectories are listed as possible branches. If
     ``svn://repo/path/tags`` exists, it is looked for tags referencing
     converted branches. Default ``trunk``, ``branches`` and ``tags``
     values can be overridden with following options. Set them to paths
     relative to the source URL, or leave them blank to disable auto
     detection.
 
     The following options can be set with ``--config``:
 
     :convert.svn.branches: specify the directory containing branches.
         The default is ``branches``.
 
     :convert.svn.tags: specify the directory containing tags. The
         default is ``tags``.
 
     :convert.svn.trunk: specify the name of the trunk branch. The
         default is ``trunk``.
 
     :convert.localtimezone: use local time (as determined by the TZ
         environment variable) for changeset date/times. The default
         is False (use UTC).
 
     Source history can be retrieved starting at a specific revision,
     instead of being integrally converted. Only single branch
     conversions are supported.
 
     :convert.svn.startrev: specify start Subversion revision number.
         The default is 0.
 
     Git Source
     ##########
 
     The Git importer converts commits from all reachable branches (refs
     in refs/heads) and remotes (refs in refs/remotes) to Mercurial.
     Branches are converted to bookmarks with the same name, with the
     leading 'refs/heads' stripped. Git submodules are converted to Git
     subrepos in Mercurial.
 
     The following options can be set with ``--config``:
 
     :convert.git.similarity: specify how similar files modified in a
         commit must be to be imported as renames or copies, as a
         percentage between ``0`` (disabled) and ``100`` (files must be
         identical). For example, ``90`` means that a delete/add pair will
         be imported as a rename if more than 90% of the file hasn't
         changed. The default is ``50``.
 
     :convert.git.findcopiesharder: while detecting copies, look at all
         files in the working copy instead of just changed ones. This
         is very expensive for large projects, and is only effective when
         ``convert.git.similarity`` is greater than 0. The default is False.
 
     :convert.git.remoteprefix: remote refs are converted as bookmarks with
         ``convert.git.remoteprefix`` as a prefix followed by a /. The default
         is 'remote'.
 
     :convert.git.skipsubmodules: does not convert root level .gitmodules files
         or files with 160000 mode indicating a submodule. Default is False.
 
     Perforce Source
     ###############
 
     The Perforce (P4) importer can be given a p4 depot path or a
     client specification as source. It will convert all files in the
     source to a flat Mercurial repository, ignoring labels, branches
     and integrations. Note that when a depot path is given you then
     usually should specify a target directory, because otherwise the
     target may be named ``...-hg``.
 
     The following options can be set with ``--config``:
 
     :convert.p4.encoding: specify the encoding to use when decoding standard
         output of the Perforce command line tool. The default is default system
         encoding.
 
     :convert.p4.startrev: specify initial Perforce revision (a
         Perforce changelist number).
 
     Mercurial Destination
     #####################
 
     The Mercurial destination will recognize Mercurial subrepositories in the
     destination directory, and update the .hgsubstate file automatically if the
     destination subrepositories contain the <dest>/<sub>/.hg/shamap file.
     Converting a repository with subrepositories requires converting a single
     repository at a time, from the bottom up.
 
     .. container:: verbose
 
        An example showing how to convert a repository with subrepositories::
 
          # so convert knows the type when it sees a non empty destination
          $ hg init converted
 
          $ hg convert orig/sub1 converted/sub1
          $ hg convert orig/sub2 converted/sub2
          $ hg convert orig converted
 
     The following options are supported:
 
     :convert.hg.clonebranches: dispatch source branches in separate
         clones. The default is False.
 
     :convert.hg.tagsbranch: branch name for tag revisions, defaults to
         ``default``.
 
     :convert.hg.usebranchnames: preserve branch names. The default is
         True.
 
     :convert.hg.sourcename: records the given string as a 'convert_source' extra
         value on each commit made in the target repository. The default is None.
 
     All Destinations
     ################
 
     All destination types accept the following options:
 
     :convert.skiptags: does not convert tags from the source repo to the target
         repo. The default is False.

 """automatically manage newlines in repository files
 
 This extension allows you to manage the type of line endings (CRLF or
 LF) that are used in the repository and in the local working
 directory. That way you can get CRLF line endings on Windows and LF on
 Unix/Mac, thereby letting everybody use their OS native line endings.
 
 The extension reads its configuration from a versioned ``.hgeol``
 configuration file found in the root of the working directory. The
 ``.hgeol`` file use the same syntax as all other Mercurial
 configuration files. It uses two sections, ``[patterns]`` and
 ``[repository]``.
 
 The ``[patterns]`` section specifies how line endings should be
 converted between the working directory and the repository. The format is
 specified by a file pattern. The first match is used, so put more
 specific patterns first. The available line endings are ``LF``,
 ``CRLF``, and ``BIN``.
 
 Files with the declared format of ``CRLF`` or ``LF`` are always
 checked out and stored in the repository in that format and files
 declared to be binary (``BIN``) are left unchanged. Additionally,
 ``native`` is an alias for checking out in the platform's default line
 ending: ``LF`` on Unix (including Mac OS X) and ``CRLF`` on
 Windows. Note that ``BIN`` (do nothing to line endings) is Mercurial's
 default behavior; it is only needed if you need to override a later,
 more general pattern.
 
 The optional ``[repository]`` section specifies the line endings to
 use for files stored in the repository. It has a single setting,
 ``native``, which determines the storage line endings for files
 declared as ``native`` in the ``[patterns]`` section. It can be set to
 ``LF`` or ``CRLF``. The default is ``LF``. For example, this means
 that on Windows, files configured as ``native`` (``CRLF`` by default)
 will be converted to ``LF`` when stored in the repository. Files
 declared as ``LF``, ``CRLF``, or ``BIN`` in the ``[patterns]`` section
 are always stored as-is in the repository.
 
 Example versioned ``.hgeol`` file::
 
   [patterns]
   **.py = native
   **.vcproj = CRLF
   **.txt = native
   Makefile = LF
   **.jpg = BIN
 
   [repository]
   native = LF
 
 .. note::
 
    The rules will first apply when files are touched in the working
    directory, e.g. by updating to null and back to tip to touch all files.
 
 The extension uses an optional ``[eol]`` section read from both the
 normal Mercurial configuration files and the ``.hgeol`` file, with the
 latter overriding the former. You can use that section to control the
 overall behavior. There are three settings:
 
 - ``eol.native`` (default ``os.linesep``) can be set to ``LF`` or
   ``CRLF`` to override the default interpretation of ``native`` for
   checkout. This can be used with :hg:`archive` on Unix, say, to
   generate an archive where files have line endings for Windows.
 
 - ``eol.only-consistent`` (default True) can be set to False to make
   the extension convert files with inconsistent EOLs. Inconsistent
   means that there is both ``CRLF`` and ``LF`` present in the file.
   Such files are normally not touched under the assumption that they
   have mixed EOLs on purpose.
 
 - ``eol.fix-trailing-newline`` (default False) can be set to True to
   ensure that converted files end with a EOL character (either ``\\n``
   or ``\\r\\n`` as per the configured patterns).
 
 The extension provides ``cleverencode:`` and ``cleverdecode:`` filters
 like the deprecated win32text extension does. This means that you can
 disable win32text and enable eol and your filters will still work. You
 only need to these filters until you have prepared a ``.hgeol`` file.
 
 The ``win32text.forbid*`` hooks provided by the win32text extension
 have been unified into a single hook named ``eol.checkheadshook``. The
 hook will lookup the expected line endings from the ``.hgeol`` file,
 which means you must migrate to a ``.hgeol`` file first before using
 the hook. ``eol.checkheadshook`` only checks heads, intermediate
 invalid revisions will be pushed. To forbid them completely, use the
 ``eol.checkallhook`` hook. These hooks are best used as
 ``pretxnchangegroup`` hooks.
 
 See :hg:`help patterns` for more information about the glob patterns
 used.

 '''command to allow external programs to compare revisions
 
 The extdiff Mercurial extension allows you to use external programs
 to compare revisions, or revision with working directory. The external
 diff programs are called with a configurable set of options and two
 non-option arguments: paths to directories containing snapshots of
 files to compare.
 
 The extdiff extension also allows you to configure new diff commands, so
 you do not need to type :hg:`extdiff -p kdiff3` always. ::
 
   [extdiff]
   # add new command that runs GNU diff(1) in 'context diff' mode
   cdiff = gdiff -Nprc5
   ## or the old way:
   #cmd.cdiff = gdiff
   #opts.cdiff = -Nprc5
 
   # add new command called meld, runs meld (no need to name twice).  If
   # the meld executable is not available, the meld tool in [merge-tools]
   # will be used, if available
   meld =
 
   # add new command called vimdiff, runs gvimdiff with DirDiff plugin
   # (see http://www.vim.org/scripts/script.php?script_id=102) Non
   # English user, be sure to put "let g:DirDiffDynamicDiffText = 1" in
   # your .vimrc
   vimdiff = gvim -f "+next" \\
             "+execute 'DirDiff' fnameescape(argv(0)) fnameescape(argv(1))"
 
 Tool arguments can include variables that are expanded at runtime::
 
   $parent1, $plabel1 - filename, descriptive label of first parent
   $child,   $clabel  - filename, descriptive label of child revision
   $parent2, $plabel2 - filename, descriptive label of second parent
   $root              - repository root
   $parent is an alias for $parent1.
 
 The extdiff extension will look in your [diff-tools] and [merge-tools]
 sections for diff tool arguments, when none are specified in [extdiff].
 
 ::
 
   [extdiff]
   kdiff3 =
 
   [diff-tools]
   kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child
 
 You can use -I/-X and list of file or directory names like normal
 :hg:`diff` command. The extdiff extension makes snapshots of only
 needed files, so running the external diff program will actually be
 pretty fast (at least faster than having to compare the entire tree).

 On a particular Linux system, for a real-world repository with over 400,000
 files hosted on ext4, vanilla `hg status` takes 1.3 seconds. On the same
 system, with fsmonitor it takes about 0.3 seconds.
 
 fsmonitor requires no configuration -- it will tell Watchman about your
 repository as necessary. You'll need to install Watchman from
 https://facebook.github.io/watchman/ and make sure it is in your PATH.
 
 The following configuration options exist:
 
 ::
 
     [fsmonitor]
     mode = {off, on, paranoid}
 
 When `mode = off`, fsmonitor will disable itself (similar to not loading the
 extension at all). When `mode = on`, fsmonitor will be enabled (the default).
 When `mode = paranoid`, fsmonitor will query both Watchman and the filesystem,
 and ensure that the results are consistent.
 
 ::
 
     [fsmonitor]
     timeout = (float)
 
 A value, in seconds, that determines how long fsmonitor will wait for Watchman
 to return results. Defaults to `2.0`.
 
 ::
 
     [fsmonitor]
     blacklistusers = (list of userids)
 
 A list of usernames for which fsmonitor will disable itself altogether.
 
 ::
 
     [fsmonitor]
     walk_on_invalidate = (boolean)
 
 Whether or not to walk the whole repo ourselves when our cached state has been
 invalidated, for example when Watchman has been restarted or .hgignore rules
 have been changed. Walking the repo in that case can result in competing for
 I/O with Watchman. For large repos it is recommended to set this value to
 false. You may wish to set this to true if you have a very fast filesystem
 that can outpace the IPC overhead of getting the result data for the full repo
 from Watchman. Defaults to false.
 
 fsmonitor is incompatible with the largefiles and eol extensions, and
 will disable itself if any of those are active.

 # Platforms Supported
 # ===================
 #
 # **Linux:** *Stable*. Watchman and fsmonitor are both known to work reliably,
 #   even under severe loads.
 #
 # **Mac OS X:** *Stable*. The Mercurial test suite passes with fsmonitor
 #   turned on, on case-insensitive HFS+. There has been a reasonable amount of
 #   user testing under normal loads.
 #
 # **Solaris, BSD:** *Alpha*. watchman and fsmonitor are believed to work, but
 #   very little testing has been done.
 #
 # **Windows:** *Alpha*. Not in a release version of watchman or fsmonitor yet.
 #
 # Known Issues
 # ============
 #
 # * fsmonitor will disable itself if any of the following extensions are
 #   enabled: largefiles, inotify, eol; or if the repository has subrepos.
 # * fsmonitor will produce incorrect results if nested repos that are not
 #   subrepos exist. *Workaround*: add nested repo paths to your `.hgignore`.
 #
 # The issues related to nested repos and subrepos are probably not fundamental
 # ones. Patches to fix them are welcome.

 '''browse the repository in a graphical way
 
 The hgk extension allows browsing the history of a repository in a
 graphical way. It requires Tcl/Tk version 8.4 or later. (Tcl/Tk is not
 distributed with Mercurial.)
 
 hgk consists of two parts: a Tcl script that does the displaying and
 querying of information, and an extension to Mercurial named hgk.py,
 which provides hooks for hgk to get information. hgk can be found in
 the contrib directory, and the extension is shipped in the hgext
 repository, and needs to be enabled.
 
 The :hg:`view` command will launch the hgk Tcl script. For this command
 to work, hgk must be in your search path. Alternately, you can specify
 the path to hgk in your configuration file::
 
   [hgk]
   path = /location/of/hgk
 
 hgk can make use of the extdiff extension to visualize revisions.
 Assuming you had already configured extdiff vdiff command, just add::
 
   [hgk]
   vdiff=vdiff
 
 Revisions context menu will now display additional entries to fire
 vdiff on hovered and selected revisions.

 """interactive history editing
 
 With this extension installed, Mercurial gains one new command: histedit. Usage
 is as follows, assuming the following history::
 
  @  3[tip]   7c2fd3b9020c   2009-04-27 18:04 -0500   durin42
  |    Add delta
  |
  o  2   030b686bedc4   2009-04-27 18:04 -0500   durin42
  |    Add gamma
  |
  o  1   c561b4e977df   2009-04-27 18:04 -0500   durin42
  |    Add beta
  |
  o  0   d8d2fcd0e319   2009-04-27 18:04 -0500   durin42
       Add alpha
 
 If you were to run ``hg histedit c561b4e977df``, you would see the following
 file open in your editor::
 
  pick c561b4e977df Add beta
  pick 030b686bedc4 Add gamma
  pick 7c2fd3b9020c Add delta
 
  # Edit history between c561b4e977df and 7c2fd3b9020c
  #
  # Commits are listed from least to most recent
  #
  # Commands:
  #  p, pick = use commit
  #  e, edit = use commit, but stop for amending
  #  f, fold = use commit, but combine it with the one above
  #  r, roll = like fold, but discard this commit's description
  #  d, drop = remove commit from history
  #  m, mess = edit commit message without changing commit content
  #
 
 In this file, lines beginning with ``#`` are ignored. You must specify a rule
 for each revision in your history. For example, if you had meant to add gamma
 before beta, and then wanted to add delta in the same revision as beta, you
 would reorganize the file to look like this::
 
  pick 030b686bedc4 Add gamma
  pick c561b4e977df Add beta
  fold 7c2fd3b9020c Add delta
 
  # Edit history between c561b4e977df and 7c2fd3b9020c
  #
  # Commits are listed from least to most recent
  #
  # Commands:
  #  p, pick = use commit
  #  e, edit = use commit, but stop for amending
  #  f, fold = use commit, but combine it with the one above
  #  r, roll = like fold, but discard this commit's description
  #  d, drop = remove commit from history
  #  m, mess = edit commit message without changing commit content
  #
 
 At which point you close the editor and ``histedit`` starts working. When you
 specify a ``fold`` operation, ``histedit`` will open an editor when it folds
 those revisions together, offering you a chance to clean up the commit message::
 
  Add beta
  ***
  Add delta
 
 Edit the commit message to your liking, then close the editor. For
 this example, let's assume that the commit message was changed to
 ``Add beta and delta.`` After histedit has run and had a chance to
 remove any old or temporary revisions it needed, the history looks
 like this::
 
  @  2[tip]   989b4d060121   2009-04-27 18:04 -0500   durin42
  |    Add beta and delta.
  |
  o  1   081603921c3f   2009-04-27 18:04 -0500   durin42
  |    Add gamma
  |
  o  0   d8d2fcd0e319   2009-04-27 18:04 -0500   durin42
       Add alpha
 
 Note that ``histedit`` does *not* remove any revisions (even its own temporary
 ones) until after it has completed all the editing operations, so it will
 probably perform several strip operations when it's done. For the above example,
 it had to run strip twice. Strip can be slow depending on a variety of factors,
 so you might need to be a little patient. You can choose to keep the original
 revisions by passing the ``--keep`` flag.
 
 The ``edit`` operation will drop you back to a command prompt,
 allowing you to edit files freely, or even use ``hg record`` to commit
 some changes as a separate commit. When you're done, any remaining
 uncommitted changes will be committed as well. When done, run ``hg
 histedit --continue`` to finish this step. You'll be prompted for a
 new commit message, but the default commit message will be the
 original message for the ``edit`` ed revision.
 
 The ``message`` operation will give you a chance to revise a commit
 message without changing the contents. It's a shortcut for doing
 ``edit`` immediately followed by `hg histedit --continue``.
 
 If ``histedit`` encounters a conflict when moving a revision (while
 handling ``pick`` or ``fold``), it'll stop in a similar manner to
 ``edit`` with the difference that it won't prompt you for a commit
 message when done. If you decide at this point that you don't like how
 much work it will be to rearrange history, or that you made a mistake,
 you can use ``hg histedit --abort`` to abandon the new changes you
 have made and return to the state before you attempted to edit your
 history.
 
 If we clone the histedit-ed example repository above and add four more
 changes, such that we have the following history::
 
    @  6[tip]   038383181893   2009-04-27 18:04 -0500   stefan
    |    Add theta
    |
    o  5   140988835471   2009-04-27 18:04 -0500   stefan
    |    Add eta
    |
    o  4   122930637314   2009-04-27 18:04 -0500   stefan
    |    Add zeta
    |
    o  3   836302820282   2009-04-27 18:04 -0500   stefan
    |    Add epsilon
    |
    o  2   989b4d060121   2009-04-27 18:04 -0500   durin42
    |    Add beta and delta.
    |
    o  1   081603921c3f   2009-04-27 18:04 -0500   durin42
    |    Add gamma
    |
    o  0   d8d2fcd0e319   2009-04-27 18:04 -0500   durin42
         Add alpha
 
 If you run ``hg histedit --outgoing`` on the clone then it is the same
 as running ``hg histedit 836302820282``. If you need plan to push to a
 repository that Mercurial does not detect to be related to the source
 repo, you can add a ``--force`` option.
 
 Config
 ------
 
 Histedit rule lines are truncated to 80 characters by default. You
 can customize this behavior by setting a different length in your
 configuration file::
 
   [histedit]
   linelen = 120      # truncate rule lines at 120 characters
 
 ``hg histedit`` attempts to automatically choose an appropriate base
 revision to use. To change which base revision is used, define a
 revset in your configuration file::
 
   [histedit]
   defaultrev = only(.) & draft()
 
 By default each edited revision needs to be present in histedit commands.
 To remove revision you need to use ``drop`` operation. You can configure
 the drop to be implicit for missing commits by adding::
 
   [histedit]
   dropmissing = True

     This command lets you edit a linear series of changesets (up to
     and including the working directory, which should be clean).
     You can:
 
     - `pick` to [re]order a changeset
 
     - `drop` to omit changeset
 
     - `mess` to reword the changeset commit message
 
     - `fold` to combine it with the preceding changeset
 
     - `roll` like fold, but discarding this commit's description
 
     - `edit` to edit this changeset
 
     There are a number of ways to select the root changeset:
 
     - Specify ANCESTOR directly
 
     - Use --outgoing -- it will be the first linear changeset not
       included in destination. (See :hg:`help config.paths.default-push`)
 
     - Otherwise, the value from the "histedit.defaultrev" config option
       is used as a revset to select the base revision when ANCESTOR is not
       specified. The first revision returned by the revset is used. By
       default, this selects the editable history that is unique to the
       ancestry of the working directory.
 
     .. container:: verbose
 
        If you use --outgoing, this command will abort if there are ambiguous
        outgoing revisions. For example, if there are multiple branches
        containing outgoing revisions.
 
        Use "min(outgoing() and ::.)" or similar revset specification
        instead of --outgoing to specify edit target revision exactly in
        such ambiguous situation. See :hg:`help revsets` for detail about
        selecting revisions.
 
     .. container:: verbose
 
        Examples:
 
          - A number of changes have been made.
            Revision 3 is no longer needed.
 
            Start history editing from revision 3::
 
              hg histedit -r 3
 
            An editor opens, containing the list of revisions,

            Additional information about the possible actions
            to take appears below the list of revisions.
 
            To remove revision 3 from the history,
            its action (at the beginning of the relevant line)

 # keyword.py - $Keyword$ expansion for Mercurial

 #
 # Keyword expansion hack against the grain of a Distributed SCM
 #
 # There are many good reasons why this is not needed in a distributed
 # SCM, still it may be useful in very small projects based on single
 # files (like LaTeX packages), that are mostly addressed to an
 # audience not running a version control system.
 #
 # For in-depth discussion refer to
 # <https://mercurial-scm.org/wiki/KeywordPlan>.
 #
 # Keyword expansion is based on Mercurial's changeset template mappings.
 #
 # Binary files are not touched.
 #
 # Files to act upon/ignore are specified in the [keyword] section.
 # Customized keyword template mappings in the [keywordmaps] section.
 #
 # Run "hg help keyword" and "hg kwdemo" to get info on configuration.
 
 '''expand keywords in tracked files
 
 This extension expands RCS/CVS-like or self-customized $Keywords$ in
 tracked text files selected by your configuration.
 
 Keywords are only expanded in local repositories and not stored in the
 change history. The mechanism can be regarded as a convenience for the
 current user or for archive distribution.
 
 Keywords expand to the changeset data pertaining to the latest change
 relative to the working directory parent of each file.
 
 Configuration is done in the [keyword], [keywordset] and [keywordmaps]
 sections of hgrc files.
 
 Example::
 
     [keyword]
     # expand keywords in every python file except those matching "x*"
     **.py =
     x*    = ignore
 
     [keywordset]
     # prefer svn- over cvs-like default keywordmaps
     svn = True
 
 .. note::
 
    The more specific you are in your filename patterns the less you
    lose speed in huge repositories.
 
 For [keywordmaps] template mapping and expansion demonstration and
 control run :hg:`kwdemo`. See :hg:`help templates` for a list of
 available templates and filters.
 
 Three additional date template filters are provided:
 
 :``utcdate``:    "2006/09/18 15:13:13"
 :``svnutcdate``: "2006-09-18 15:13:13Z"
 :``svnisodate``: "2006-09-18 08:13:13 -700 (Mon, 18 Sep 2006)"
 
 The default template mappings (view with :hg:`kwdemo -d`) can be
 replaced with customized keywords and templates. Again, run
 :hg:`kwdemo` to control the results of your configuration changes.
 
 Before changing/disabling active keywords, you must run :hg:`kwshrink`
 to avoid storing expanded keywords in the change history.
 
 To force expansion after enabling it, or a configuration change, run
 :hg:`kwexpand`.
 
 Expansions spanning more than one line and incremental expansions,
 like CVS' $Log$, are not supported. A keyword template map "Log =
 {desc}" expands to the first line of the changeset description.

 '''track large binary files
 
 Large binary files tend to be not very compressible, not very
 diffable, and not at all mergeable. Such files are not handled
 efficiently by Mercurial's storage format (revlog), which is based on
 compressed binary deltas; storing large binary files as regular
 Mercurial files wastes bandwidth and disk space and increases
 Mercurial's memory usage. The largefiles extension addresses these
 problems by adding a centralized client-server layer on top of
 Mercurial: largefiles live in a *central store* out on the network
 somewhere, and you only fetch the revisions that you need when you
 need them.
 
 largefiles works by maintaining a "standin file" in .hglf/ for each
 largefile. The standins are small (41 bytes: an SHA-1 hash plus
 newline) and are tracked by Mercurial. Largefile revisions are
 identified by the SHA-1 hash of their contents, which is written to
 the standin. largefiles uses that revision ID to get/put largefile
 revisions from/to the central store. This saves both disk space and
 bandwidth, since you don't need to retrieve all historical revisions
 of large files when you clone or pull.
 
 To start a new repository or add new large binary files, just add
 --large to your :hg:`add` command. For example::
 
   $ dd if=/dev/urandom of=randomdata count=2000
   $ hg add --large randomdata
   $ hg commit -m "add randomdata as a largefile"
 
 When you push a changeset that adds/modifies largefiles to a remote
 repository, its largefile revisions will be uploaded along with it.
 Note that the remote Mercurial must also have the largefiles extension
 enabled for this to work.
 
 When you pull a changeset that affects largefiles from a remote
 repository, the largefiles for the changeset will by default not be
 pulled down. However, when you update to such a revision, any
 largefiles needed by that revision are downloaded and cached (if
 they have never been downloaded before). One way to pull largefiles
 when pulling is thus to use --update, which will update your working
 copy to the latest pulled revision (and thereby downloading any new
 largefiles).
 
 If you want to pull largefiles you don't need for update yet, then
 you can use pull with the `--lfrev` option or the :hg:`lfpull` command.
 
 If you know you are pulling from a non-default location and want to
 download all the largefiles that correspond to the new changesets at
 the same time, then you can pull with `--lfrev "pulled()"`.
 
 If you just want to ensure that you will have the largefiles needed to
 merge or rebase with new heads that you are pulling, then you can pull
 with `--lfrev "head(pulled())"` flag to pre-emptively download any largefiles
 that are new in the heads you are pulling.
 
 Keep in mind that network access may now be required to update to
 changesets that you have not previously updated to. The nature of the
 largefiles extension means that updating is no longer guaranteed to
 be a local-only operation.
 
 If you already have large files tracked by Mercurial without the
 largefiles extension, you will need to convert your repository in
 order to benefit from largefiles. This is done with the
 :hg:`lfconvert` command::
 
   $ hg lfconvert --size 10 oldrepo newrepo
 
 In repositories that already have largefiles in them, any new file
 over 10MB will automatically be added as a largefile. To change this
 threshold, set ``largefiles.minsize`` in your Mercurial config file
 to the minimum size in megabytes to track as a largefile, or use the
 --lfsize option to the add command (also in megabytes)::
 
   [largefiles]
   minsize = 2
 
   $ hg add --lfsize 2
 
 The ``largefiles.patterns`` config option allows you to specify a list
 of filename patterns (see :hg:`help patterns`) that should always be
 tracked as largefiles::
 
   [largefiles]
   patterns =
     *.jpg
     re:.*\.(png|bmp)$
     library.zip
     content/audio/*
 
 Files that match one of these patterns will be added as largefiles
 regardless of their size.
 
 The ``largefiles.minsize`` and ``largefiles.patterns`` config options
 will be ignored for any repositories not already containing a
 largefile. To add the first largefile to a repository, you must
 explicitly do so with the --large flag passed to the :hg:`add`
 command.

 """Send ui.log() data to a subprocess (EXPERIMENTAL)
 
 This extension lets you specify a shell command per ui.log() event,
 sending all remaining arguments to as environment variables to that command.
 
 Each positional argument to the method results in a `MSG[N]` key in the
 environment, starting at 1 (so `MSG1`, `MSG2`, etc.). Each keyword argument
 is set as a `OPT_UPPERCASE_KEY` variable (so the key is uppercased, and
 prefixed with `OPT_`). The original event name is passed in the `EVENT`
 environment variable, and the process ID of mercurial is given in `HGPID`.
 
 So given a call `ui.log('foo', 'bar', 'baz', spam='eggs'), a script configured
 for the `foo` event can expect an environment with `MSG1=bar`, `MSG2=baz`, and
 `OPT_SPAM=eggs`.
 
 Scripts are configured in the `[logtoprocess]` section, each key an event name.
 For example::
 
   [logtoprocess]
   commandexception = echo "$MSG2$MSG3" > /var/log/mercurial_exceptions.log
 
 would log the warning message and traceback of any failed command dispatch.
 
 Scripts are run asychronously as detached daemon processes; mercurial will
 not ensure that they exit cleanly.
