     Use the -s/--similarity option to detect renamed files. This
     option takes a percentage between 0 (disabled) and 100 (files must
     be identical) as its parameter. With a parameter greater than 0,
     this compares every removed file with every added file and records
     those similar enough as renames. Detecting renamed files this way
     can be expensive. After using this option, :hg:`status -C` can be
     used to check which files were identified as moved or renamed. If
     not specified, -s/--similarity defaults to 100 and only renames of
     identical files are detected.

     If you include --file, --user, or --date, the revision number is

     Prepare a new changeset with the effect of REV undone in the
     current working directory. If no conflicts were encountered,
     it will be committed immediately.
 
     If REV is the parent of the working directory, then this new changeset
     is committed automatically (unless --no-commit is specified).
 
     .. note::
 
        :hg:`backout` cannot be used to fix either an unwanted or
        incorrect merge.
 
     .. container:: verbose
 
       Examples:
 
       - Reverse the effect of the parent of the working directory.
         This backout will be committed immediately::
 
           hg backout -r .
 
       - Reverse the effect of previous bad revision 23::
 
           hg backout -r 23
 
       - Reverse the effect of previous bad revision 23 and
         leave changes uncommitted::
 
           hg backout -r 23 --no-commit
           hg commit -m "Backout revision 23"
 
       By default, the pending changeset will have one parent,
       maintaining a linear history. With --merge, the pending
       changeset will instead have two parents: the old parent of the
       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/-d/-l 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
 
       Template:
 
       The following keywords are supported in addition to the common template
       keywords and functions such as ``{bookmark}``. See also
       :hg:`help templates`.
 
       :active:  Boolean. True if the bookmark is active.
 
       Examples:
 
       - create an active bookmark for a new line of development::
 
           hg book new-feature
 
       - create an inactive bookmark as a place marker::
 
           hg book -i reviewed
 
       - create an inactive bookmark on another changeset::
 
           hg book -r .^ tested
 
       - rename bookmark turkey to dinner::
 
           hg book -m turkey dinner
 
       - move the '@' bookmark from another branch::

     Create a copy of an existing repository in a new directory.
 
     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

       When cloning from servers that support it, Mercurial may fetch
       pre-generated data from a server-advertised URL or inline from the
       same stream. When this is done, hooks operating on incoming changesets
       and changegroups may fire more than once, once for each pre-generated
       bundle and as well as for any additional remaining data. 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 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::
 
           hg clone -r 04e544 experimental/ good/
 
       - clone (and track) a particular named branch::
 
           hg clone https://www.mercurial-scm.org/repo/hg/#stable
 
     See :hg:`help urls` for details on specifying URLs.

     Commit changes to the given files into the repository. Unlike a
     centralized SCM, this operation is a local operation. See
     :hg:`push` for a way to actively distribute your changes.
 
     If a list of files is omitted, all changes reported by :hg:`status`
     will be committed.
 
     If you are committing the result of a merge, do not provide any
     filenames or -I/-X filters.
 
     If no commit message is specified, Mercurial starts your
     configured editor where you can enter a message. In case your
     commit fails, you will find a backup of your message in
     ``.hg/last-message.txt``.
 
     The --close-branch flag can be used to mark the current branch
     head closed. When all heads of a branch are closed, the branch
     will be considered closed and no longer listed.
 
     The --amend flag can be used to amend the parent of the
     working directory with a new commit that contains the changes
     in the parent in addition to those currently reported by :hg:`status`,
     if there are any. The old commit is stored in a backup bundle in
     ``.hg/strip-backup`` (see :hg:`help bundle` and :hg:`help unbundle`
     on how to restore it).
 
     Message, user and date are taken from the amended commit unless
     specified. When a message isn't specified on the command line,
     the editor will open with the message of the amended commit.
 
     It is not possible to amend public changesets (see :hg:`help phases`)

     When two revision arguments are given, then changes are shown

     the changes in that changeset relative to its first parent.
 
     Without the -a/--text option, diff will avoid generating diffs of
     files it detects as binary. With -a, diff will generate a diff
     anyway, probably with undesirable results.

     Print the changeset header and diffs for one or more revisions.
     If no revision is given, the parent of the working directory is used.
 
     The information shown in the changeset header is: author, date,
     branch name (if non-default), changeset hash, parent(s) and commit
     comment.
 
     .. note::
 
        :hg:`export` may generate unexpected diff output for merge
        changesets, as it will compare the merge changeset against its
        first parent only.
 
     Output may be to a file, in which case the name of the file is
     given using a template string. See :hg:`help templates`. In addition
     to the common template keywords, the following formatting rules are
     supported:
 
     :``%%``: literal "%" character
     :``%H``: changeset hash (40 hexadecimal digits)
     :``%N``: number of patches being generated
     :``%R``: changeset revision number
     :``%b``: basename of the exporting repository
     :``%h``: short-form changeset hash (12 hexadecimal digits)
     :``%m``: first line of the commit message (only alphanumeric characters)
     :``%n``: zero-padded sequence number, starting at 1
     :``%r``: zero-padded changeset revision number
     :``\\``: literal "\\" character
 
     Without the -a/--text option, export will avoid generating diffs
     of files it detects as binary. With -a, export will generate a
     diff anyway, probably with undesirable results.
 
     With -B/--bookmark changesets reachable by the given bookmark are
     selected.
 
     Use the -g/--git option to generate diffs in the git extended diff
     format. See :hg:`help diffs` for more information.
 
     With the --switch-parent option, the diff will be against the
     second parent. It can be useful to review a merge.

     '''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.
 
     The -c/--continue option reapplies all the earlier options.
 
     .. container:: verbose
 
       The --base option exposes more of how graft internally uses merge with a
       custom base revision. --base can be used to specify another ancestor than
       the first and only parent.
 
       The command::
 
         hg graft -r 345 --base 234
 
       is thus pretty much the same as::
 
         hg diff -r 234 -r 345 | hg import
 
       but using merge to resolve conflicts and track moved files.
 
       The result of a merge can thus be backported as a single commit by
       specifying one of the merge parents as base, and thus effectively
       grafting the changes from the other side.
 
       It is also possible to collapse multiple changesets and clean up history
       by specifying another ancestor as base, much like rebase --collapse
       --keep.
 
       The commit message can be tweaked after the fact using commit --amend .
 
       For using non-ancestors as the base to backout changes, see the backout
       command and the hidden --parent option.
 
     .. 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)"
 
       - backport the result of a merge as a single commit::
 
           hg graft -r 123 --base 123^
 
       - land a feature branch as one changeset::
 
           hg up -cr default
           hg graft -r featureX --base "ancestor('featureX', 'default')"

     a non-match, or "+" for a non-match that becomes a match), use the

     """import an ordered set of patches
 
     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

         BM2               1234567890ab advanced

         BM4               34567890abcd changed
 
       The action taken locally when pulling depends on the
       status of each bookmark:
 
       :``added``: pull will create it
       :``advanced``: pull will update it
       :``diverged``: pull will create a divergent bookmark
       :``changed``: result depends on remote changesets
 
       From the point of view of pulling behavior, bookmark
       existing only in the remote repository are treated as ``added``,
       even if it is in fact locally deleted.
 
     .. container:: verbose
 
       For remote repository, using --bundle avoids downloading the
       changesets twice if the incoming is followed by a pull.
 
       Examples:
 
       - show incoming changes with patches and full description::
 
           hg incoming -vp
 
       - show incoming changes excluding merges, store a bundle::

     If no revision range is specified, the default is ``tip:0`` unless

     used as the starting revision.
 
     File history is shown without following rename or copy history of
     files. Use -f/--follow with a filename to follow history across
     renames and copies. --follow without a filename will only show
     ancestors of the starting revision.

     tags, non-trivial parents, user, date and time, and a summary for
     each commit. When the -v/--verbose switch is used, the list of
     changed files and full commit message are shown.
 
     With --graph the revisions are shown as an ASCII art DAG with the most
     recent changeset at the top.
     'o' is a changeset, '@' is a working directory parent, '_' closes a branch,
     'x' is obsolete, '*' is unstable, and '+' represents a fork where the
     changeset from the lines below is a parent of the 'o' merge on the same
     line.
     Paths in the DAG are represented with '|', '/' and so forth. ':' in place
     of a '|' indicates one or more revisions in a path are omitted.
 
     .. container:: verbose
 
        Use -L/--line-range FILE,M:N options to follow the history of lines
        from M to N in FILE. With -p/--patch only diff hunks affecting
        specified line range will be shown. This option requires --follow;
        it can be specified multiple times. Currently, this option is not
        compatible with --graph. This option is experimental.
 
     .. note::
 
        :hg:`log --patch` may generate unexpected diff output for merge
        changesets, as it will only compare the merge changeset against
        its first parent. Also, only files different from BOTH parents
        will appear in files:.
 
     .. note::
 
        For performance reasons, :hg:`log FILE` may omit duplicate changes
        made on branches and will not show removals or mode changes. To
        see all such changes, use the --removed switch.
 
     .. container:: verbose
 
        .. note::
 
           The history resulting from -L/--line-range options depends on diff
           options; for instance if white-spaces are ignored, respective changes
           with only white-spaces in specified line range will not be listed.

       - list available log templates::
 
           hg log -T list
 
       - check if a given changeset is included in a tagged release::
 
           hg log -r "a21ccf and ancestor(1.9)"
 
       - find all changesets by some user in a date range::

     Files that changed between either parent are marked as changed for
     the next commit and a commit must be performed before any further
     updates to the repository are allowed. The next commit will have
     two parents.
 
     ``--tool`` can be used to specify the merge tool used for file
     merges. It overrides the HGMERGE environment variable and your
     configuration files. See :hg:`help merge-tools` for options.
 
     If no revision is specified, the working directory's parent is a
     head revision, and the current branch contains exactly one other
     head, the other head is merged with by default. Otherwise, an
     explicit revision with which to merge with must be provided.
 
     See :hg:`help resolve` for information on handling file conflicts.

     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
     setting, or a command-line merge tool like ``diff3``. The resolve
     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 [--re-merge] [--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

        use :hg:`merge --abort`.
 
     With no revision specified, revert the specified files or directories
     to the contents they had in the parent of the working directory.
     This restores the contents of files to an unmodified
     state and unschedules adds, removes, copies, and renames. If the
     working directory has two parents, you must explicitly specify a
     revision.
 
     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
     option.

     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.

     """show changed files in the working directory
 
     Show status of files in the repository. If names are given, only
     files that match are shown. Files that are clean or ignored or
     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 only the directory
       name if all the files in it share the same status. The option takes an
       argument indicating the statuses to abbreviate: 'm' for 'modified', 'a'
       for 'added', 'r' for 'removed', 'd' for 'deleted', 'u' for 'unknown', 'i'
       for 'ignored' and 'c' for clean.
 
       It abbreviates only those statuses which are passed. Note that clean and
       ignored files are not displayed with '--terse ic' unless the -c/--clean
       and -i/--ignored options are also used.
 
       The -v/--verbose option shows information when the repository is in an
       unfinished merge, shelve, rebase state etc. You can have this behavior
       turned on by default by enabling the ``commands.status.verbose`` option.
 
       You can skip displaying some of these states by setting
       ``commands.status.skipstates`` to one or more of: 'bisect', 'graft',
       'histedit', 'merge', 'rebase', or 'unshelve'.
 
       Template:
 
       The following keywords are supported in addition to the common template
       keywords and functions. See also :hg:`help templates`.
 
       :path:    String. Repository-absolute path of the file.
       :source:  String. Repository-absolute path of the file originated from.
                 Available if ``--copies`` is specified.
       :status:  String. Character denoting file's status.
 
       Examples:
 
       - show changes in the working directory relative to a
         changeset::
 
           hg status --rev 9353
 
       - show changes in the working directory relative to the
         current directory (see :hg:`help patterns` for more information)::
 
           hg status re:
 
       - show all changes including copies in an existing changeset::
 
           hg status --copies --change 9353
 
       - get a NUL separated list of added files, suitable for xargs::
 
           hg status -an0
 
       - show more information about the repository status, abbreviating
         added, removed, modified, deleted, and untracked paths::
 
           hg status -v -t mardu
 
     Returns 0 on success.

     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.

 In repositories that have accumulated a large number of files over time, the
 fncache file is going to be large. If we possibly can avoid loading it, so much the better.
 The cache should not loaded when committing changes to existing files, or when unbundling
 changesets that only contain changes to existing files:
 
   $ cat > fncacheloadwarn.py << EOF
   > from __future__ import absolute_import
   > from mercurial import extensions, localrepo
   > 
   > def extsetup(ui):
   >     def wrapstore(orig, requirements, *args):
   >         store = orig(requirements, *args)
   >         if b'store' in requirements and b'fncache' in requirements:
   >             instrumentfncachestore(store, ui)
   >         return store
   >     extensions.wrapfunction(localrepo, 'makestore', wrapstore)
   > 
   > def instrumentfncachestore(fncachestore, ui):
   >     class instrumentedfncache(type(fncachestore.fncache)):
   >         def _load(self):
   >             ui.warn(b'fncache load triggered!\n')
   >             super(instrumentedfncache, self)._load()
   >     fncachestore.fncache.__class__ = instrumentedfncache
   > EOF
 
   $ fncachextpath=`pwd`/fncacheloadwarn.py
   $ hg init nofncacheload
   $ cd nofncacheload
   $ printf "[extensions]\nfncacheloadwarn=$fncachextpath\n" >> .hg/hgrc
 
 A new file should trigger a load, as we'd want to update the fncache set in that case:
 
   $ touch foo
   $ hg ci -qAm foo
   fncache load triggered!
 
 But modifying that file should not:
 
   $ echo bar >> foo
   $ hg ci -qm foo
 
 If a transaction has been aborted, the zero-size truncated index file will
 not prevent the fncache from being loaded; rather than actually abort
 a transaction, we simulate the situation by creating a zero-size index file:
 
   $ touch .hg/store/data/bar.i
   $ touch bar
   $ hg ci -qAm bar
   fncache load triggered!
 
 Unbundling should follow the same rules; existing files should not cause a load:
 
   $ hg clone -q . tobundle
   $ echo 'new line' > tobundle/bar
   $ hg -R tobundle ci -qm bar
   $ hg -R tobundle bundle -q barupdated.hg
   $ hg unbundle -q barupdated.hg
 
 but adding new files should:
 
   $ touch tobundle/newfile
   $ hg -R tobundle ci -qAm newfile
   $ hg -R tobundle bundle -q newfile.hg
   $ hg unbundle -q newfile.hg
   fncache load triggered!

 Graft from behind a move or rename
 ==================================
 
 NOTE: This is affected by issue5343, and will need updating when it's fixed
 
 Possible cases during a regular graft (when ca is between cta and c2):
 
 name | c1<-cta | cta<->ca | ca->c2
 A.0  |         |          |
 A.1  |    X    |          |
 A.2  |         |     X    |
 A.3  |         |          |   X
 A.4  |    X    |     X    |
 A.5  |    X    |          |   X
 A.6  |         |     X    |   X
 A.7  |    X    |     X    |   X
 
 A.0 is trivial, and doesn't need copy tracking.
 For A.1, a forward rename is recorded in the c1 pass, to be followed later.
 In A.2, the rename is recorded in the c2 pass and followed backwards.
 A.3 is recorded in the c2 pass as a forward rename to be duplicated on target.
 In A.4, both passes of checkcopies record incomplete renames, which are
 then joined in mergecopies to record a rename to be followed.
 In A.5 and A.7, the c1 pass records an incomplete rename, while the c2 pass
 records an incomplete divergence. The incomplete rename is then joined to the
 appropriate side of the incomplete divergence, and the result is recorded as a
 divergence. The code doesn't distinguish at all between these two cases, since
 the end result of them is the same: an incomplete divergence joined with an
 incomplete rename into a divergence.
 Finally, A.6 records a divergence entirely in the c2 pass.
 
 A.4 has a degenerate case a<-b<-a->a, where checkcopies isn't needed at all.
 A.5 has a special case a<-b<-b->a, which is treated like a<-b->a in a merge.
 A.6 has a special case a<-a<-b->a. Here, checkcopies will find a spurious
 incomplete divergence, which is in fact complete. This is handled later in
 mergecopies.
 A.7 has 4 special cases: a<-b<-a->b (the "ping-pong" case), a<-b<-c->b,
 a<-b<-a->c and a<-b<-c->a. Of these, only the "ping-pong" case is interesting,
 the others are fairly trivial (a<-b<-c->b and a<-b<-a->c proceed like the base
 case, a<-b<-c->a is treated the same as a<-b<-b->a).
 
 f5a therefore tests the "ping-pong" rename case, where a file is renamed to the
 same name on both branches, then the rename is backed out on one branch, and
 the backout is grafted to the other branch. This creates a challenging rename
 sequence of a<-b<-a->b in the graft target, topological CA, graft CA and graft
 source, respectively. Since rename detection will run on the c1 side for such a
 sequence (as for technical reasons, we split the c1 and c2 sides not at the
 graft CA, but rather at the topological CA), it will pick up a false rename,
 and cause a spurious merge conflict. This false rename is always exactly the
 reverse of the true rename that would be detected on the c2 side, so we can
 correct for it by detecting this condition and reversing as necessary.
 
 First, set up the repository with commits to be grafted
 
   $ hg init ../graftmove
   $ cd ../graftmove

   $ hg ci -qAm A0

   $ hg mv f5a f5b
   $ hg ci -qAm B0
   $ echo c1c > f1b
   $ hg mv f2a f2c

   $ echo c5c > f5a
   $ hg ci -qAm C0

 Graft a change into a new file previously grafted into a renamed directory

   $ hg log -G -T '{rev} {desc|firstline}'

 Grafting of plain changes correctly detects that 3 and 5 should be skipped:
 
   $ hg up -qCr 4
   $ hg graft --tool :local -r 2::5
   skipping already grafted revision 3:ca093ca2f1d9 (was grafted from 1:13ec5badbf2a)
   skipping already grafted revision 5:43e9eb70dab0 (was grafted from 4:6c9a1289e5f1)
   grafting 2:42127f193bcd "b"
 
 Extending the graft range to include a (skipped) merge of 3 will not prevent us from
 also detecting that both 3 and 5 should be skipped:
 
   $ hg up -qCr 4
   $ hg graft --tool :local -r 2::7
   skipping ungraftable merge revision 6
   skipping already grafted revision 3:ca093ca2f1d9 (was grafted from 1:13ec5badbf2a)
   skipping already grafted revision 5:43e9eb70dab0 (was grafted from 4:6c9a1289e5f1)
   grafting 2:42127f193bcd "b"

 check whether HG_PENDING makes pending changes only in relatd
 repositories visible to an external hook.
 
 In "hg share" case, another transaction can't run in other
 repositories sharing same source repository, because starting
 transaction requires locking store of source repository.
 
 Therefore, this test scenario ignores checking visibility of
 .hg/bookmakrs.pending in repo2, which shares repo1 without bookmarks.

 Unfortunately, subrepos not at their nominal location cannot be cloned.  But
 they are still served from their location within the local repository.  The only
 reason why 'main' can be cloned via the filesystem is because 'sub1' and 'sub2'
 are also available as siblings of 'main'.
