errors: introduce StateError and use it from commands and cmdutil

This very similar to an earlier patch (which was for `InputError`).

In this patch, I also updated the transplant extension only because
`test-transplant.t` would otherwise have needed a `#if continueflag`.

 '''command to transplant changesets from another branch
 
 This extension allows you to transplant changes to another parent revision,
 possibly in another repository. The transplant is done using 'diff' patches.
 
 Transplanted patches are recorded in .hg/transplant/transplants, as a
 map from a changeset hash to its hash in the source repository.

     Selected changesets will be applied on top of the current working
     directory with the log of the original changeset. The changesets
     are copied and will thus appear twice in the history with different
     identities.
 
     Consider using the graft command if everything is inside the same
     repository - it will use merges and will usually give a better result.
     Use the rebase extension if the changesets are unpublished and you want
     to move them instead of copying them.
 
     If --log is specified, log messages will have a comment appended
     of the form::
 
       (transplanted from CHANGESETHASH)
 
     You can rewrite the changelog message with the --filter option.
     Its argument will be invoked with the current changelog message as
     $1 and the patch as $2.
 
     --source/-s specifies another repository to use for selecting changesets,
     just as if it temporarily had been pulled.
     If --branch/-b is specified, these revisions will be used as
     heads when deciding which changesets to transplant, just as if only
     these revisions had been pulled.
     If --all/-a is specified, all the revisions up to the heads specified
     with --branch will be transplanted.
 
     Example:
 
     - transplant all changes up to REV on top of your current revision::
 
         hg transplant --branch REV --all
 
     You can optionally mark selected transplanted changesets as merge
     changesets. You will not be prompted to transplant any ancestors
     of a merged transplant, and you can merge descendants of them
     normally instead of transplanting them.
 
     Merge changesets may be transplanted directly by specifying the
     proper parent changeset by calling :hg:`transplant --parent`.
 
     If no merges or revisions are provided, :hg:`transplant` will
     start an interactive changeset browser.
 
     If a changeset application fails, you can fix the merge by hand
     and then resume where you left off by calling :hg:`transplant
     --continue/-c`.

       - Reverse the effect of previous bad revision 23 and

           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.

     """subdivision search of changesets
 
     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::

     Generate a bundle file containing data to be transferred to another

     all the nodes you specify with --base parameters. Otherwise, hg
     will assume the repository has all the nodes in destination, or
     default-push/default if no destination is specified, where destination
     is the repository you provide through DEST option.
 
     You can change bundle format with the -t/--type option. See
     :hg:`help bundlespec` for documentation on this format. By default,
     the most appropriate format is used and compression defaults to
     bzip2.
 
     The bundle file can then be transferred using conventional means
     and applied to another repository with the unbundle or pull
     command. This is useful when direct push and pull are not
     available or when exporting an entire repository is undesirable.

 def clone(ui, source, dest=None, **opts):
     """make a copy of an existing repository
 
     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
       g) the revision marked with the '@' bookmark, if present
       h) the tipmost head of the default branch
       i) tip
 
       When cloning from servers that support it, Mercurial may fetch
       pre-generated data from a server-advertised URL 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

     working directory with a new commit that contains the changes
     in the parent in addition to those currently reported by :hg:`status`,

     '''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')"
 
     See :hg:`help revisions` for more about specifying revisions.
 
     Returns 0 on successful completion, 1 if there are unresolved files.

     Search the working directory or revision history for a regular

     By default, grep searches the repository files in the working
     directory and prints the files where it finds a match. To specify
     historical revisions instead of the working directory, use the
     --rev flag.
 
     To search instead historical revision differences that contains a
     change in match status ("-" for a match that becomes a non-match,
     or "+" for a non-match that becomes a match), use the --diff flag.
 
     PATTERN can be any Python (roughly Perl-compatible) regular
     expression.
 
     If no FILEs are specified and the --rev flag isn't supplied, all
     files in the working directory are searched. When using the --rev
     flag and specifying FILEs, use the --follow argument to also
     follow the specified FILEs across renames and copies.

       The following keywords are supported in addition to the common template
       keywords and functions. See also :hg:`help templates`.
 
       :change:  String. Character denoting insertion ``+`` or removal ``-``.
                 Available if ``--diff`` is specified.
       :lineno:  Integer. Line number of the match.
       :path:    String. Repository-absolute path of the file.
       :texts:   List of text chunks.
 
       And each entry of ``{texts}`` provides the following sub-keywords.
 
       :matched: Boolean. True if the chunk matches the specified pattern.
       :text:    String. Chunk content.

     Print a summary identifying the repository state at REV using one or

     a list of tags, and a list of bookmarks.

     repository including the working directory. Specify -r. to get information
     of the working directory parent without scanning uncommitted changes.

       Template:
 
       The following keywords are supported in addition to the common template
       keywords and functions. See also :hg:`help templates`.
 
       :dirty:   String. Character ``+`` denoting if the working directory has
                 uncommitted changes.
       :id:      String. One or two nodes, optionally followed by ``+``.
       :parents: List of strings. Parent nodes of the changeset.
 
       Examples:
 
       - generate a build identifier for the working directory::
 
           hg id --id > build-id.dat
 
       - find the revision corresponding to a tag::
 
           hg id -n -r 1.3
 
       - check the most recent revision of a remote repository::
 
           hg id -r tip https://www.mercurial-scm.org/repo/hg/
 
     See :hg:`log` for generating more information about specific revisions,
     including full hash identifiers.

 def import_(ui, repo, patch1=None, *patches, **opts):
     """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
 
       - use an external tool to apply a patch which is too fuzzy for
         the default internal tool.
 
           hg import --config ui.patch="patch --merge" fuzzy.patch
 
       - change the default fuzzing from 2 to a less strict 7
 
           hg import --config ui.fuzz=7 fuzz.patch

     Show new changesets found in the specified path/URL or the default

       With -B/--bookmarks, the result of bookmark comparison between
       local and remote repositories is displayed. With -v/--verbose,
       status is also displayed for each bookmark like below::
 
         BM1               01234567890a added
         BM2               1234567890ab advanced
         BM3               234567890abc diverged
         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::
 
           hg in -vpM --bundle incoming.hg
           hg pull incoming.hg
 
       - briefly list changes inside a bundle::
 
           hg in changes.hg -T "{desc|firstline}\\n"
 
     Returns 0 if there are incoming changes, 1 otherwise.

 def log(ui, repo, *pats, **opts):
     """show revision history of entire repository or files
 
     Print the revision history of the specified files or the entire
     project.
 
     If no revision range is specified, the default is ``tip:0`` unless
     --follow is set, in which case the working directory parent is
     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.
 
     By default this command prints revision number and changeset id,
     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, '%' is a changeset
     involved in an unresolved merge conflict, '_' 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.
 
     .. container:: verbose
 
       Some examples:
 
       - changesets with full descriptions and file lists::
 
           hg log -v

           hg log -f
 
       - last 10 commits on the current branch::

       - changesets showing all modifications of a file, including removals::
 
           hg log --removed file.c
 
       - all changesets that touch a directory, with diffs, excluding merges::
 
           hg log -Mp lib/
 
       - all revision numbers that match a keyword::
 
           hg log -k bug --template "{rev}\\n"
 
       - the full hash identifier of the working directory parent::
 
           hg log -r . --template "{node}\\n"
 
       - 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::
 
           hg log -k alice -d "may 2008 to jul 2008"
 
       - summary of all changesets after the last tag::
 
           hg log -r "last(tagged())::" --template "{desc|firstline}\\n"
 
       - changesets touching lines 13 to 23 for file.c::
 
           hg log -L file.c,13:23
 
       - changesets touching lines 13 to 23 for file.c and lines 2 to 6 of
         main.c with patch::

       :``changed``: push with ``-B`` will update it

     Pull changes from a remote repository to a local one.
 
     This finds all changes from the repository at the specified path
     or URL and adds them to a local repository (the current one unless
     -R is specified). By default, this does not update the copy of the
     project in the working directory.
 
     When cloning from servers that support it, Mercurial may fetch
     pre-generated data. 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. See :hg:`help -e clonebundles` for more.
 
     Use :hg:`incoming` if you want to see what would have been added
     by a pull at the time you issued this command. If you then decide
     to add those changes to the repository, you should use :hg:`pull
     -r X` where ``X`` is the last changeset listed by :hg:`incoming`.
 
     If SOURCE is omitted, the 'default' path will be used.
     See :hg:`help urls` for more information.

     """push changes to the specified destination
 
     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. Use the --all-bookmarks option for pushing all
     current bookmarks.
 
     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.

     """redo merges or set/view the merge status of files
 
     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
     :hg:`merge` has been run, and before :hg:`commit` is run (i.e. the
     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
        commit after a conflicting merge.
 
     .. container:: verbose
 
       Template:
 
       The following keywords are supported in addition to the common template
       keywords and functions. See also :hg:`help templates`.
 
       :mergestatus: String. Character denoting merge conflicts, ``U`` or ``R``.
       :path:    String. Repository-absolute path of the file.
 
     Returns 0 on success, 1 if any files fail a resolve attempt.

     revert does not change the working directory parents, this will

     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

     Please use :hg:`commit --amend` instead of rollback to correct
     mistakes in the last commit.
 
     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.

     Shelving takes files that "hg status" reports as not clean, saves
     the modifications to a bundle (a shelved change), and reverts the
     files so that their state in the working directory becomes clean.
 
     To restore these changes to the working directory, using "hg
     unshelve"; this will work even if you switch to a different
     commit.
 
     When no files are specified, "hg shelve" saves all not-clean
     files. If specific files or directories are named, only changes to
     those files are shelved.
 
     In bare shelve (when no files are specified, without interactive,
     include and exclude option), shelving remembers information if the
     working directory was on newly created branch, in other words working
     directory was on different branch than its first parent. In this
     situation unshelving restores branch information to the working directory.
 
     Each shelved change has a name that makes it easier to find later.
     The name of a shelved change defaults to being based on the active
     bookmark, or if there is no active bookmark, the current named
     branch.  To specify a different name, use ``--name``.
 
     To see a list of existing shelved changes, use the ``--list``
     option. For each shelved change, this will print its name, age,
     and description; use ``--patch`` or ``--stat`` for more details.
 
     To delete specific shelved changes, use ``--delete``. To delete
     all shelved changes, use ``--cleanup``.

     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'.

     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.

     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.

     This command accepts an optional name of a shelved change to

     If a shelved change is applied successfully, the bundle that
     contains the shelved changes is moved to a backup location
     (.hg/shelve-backup).
 
     Since you can restore a shelved change on top of an arbitrary
     commit, it is possible that unshelving will result in a conflict
     between your changes and the commits you are unshelving onto. If
     this occurs, you must resolve the conflict, then use
     ``--continue`` to complete the unshelve operation. (The bundle
     will not be moved until you successfully complete the unshelve.)
 
     (Alternatively, you can use ``--abort`` to abandon an unshelve
     that causes a conflict. This reverts the unshelved changes, and
     leaves the bundle in place.)
 
     If bare shelved change (without interactive, include and exclude
     option) was done on newly created branch it would restore branch
     information to the working directory.
 
     After a successful unshelve, the shelved changes are stored in a
     backup directory. Only the N most recent backups are kept. N
     defaults to 10 but can be overridden using the ``shelve.maxbackups``

        Timestamp in seconds is used to decide order of backups. More
        than ``maxbackups`` backups are kept, if same timestamp
        prevents from deciding exact order of them, for safety.
 
        Selected changes can be unshelved with ``--interactive`` flag.
        The working directory is updated with the selected changes, and
        only the unselected changes remain shelved.
        Note: The whole shelve is applied to working directory first before
        running interactively. So, this will bring up all the conflicts between
        working directory and the shelve, irrespective of which changes will be

          requested changeset is not an ancestor or descendant of

 letters to uppercase. They use different file extensions, so each test case can
 choose which behavior to use by naming files.

 Help text for fix.
 
   $ hg help fix
   hg fix [OPTION]... [FILE]...
   
   rewrite file content in changesets or working directory
   
       Runs any configured tools to fix the content of files. Only affects files
       with changes, unless file arguments are provided. Only affects changed
       lines of files, unless the --whole flag is used. Some tools may always
       affect the whole file regardless of --whole.
   
       If --working-dir is used, files with uncommitted changes in the working
       copy will be fixed. Note that no backup are made.
   
       If revisions are specified with --source, those revisions and their
       descendants will be checked, and they may be replaced with new revisions
       that have fixed file content. By automatically including the descendants,
       no merging, rebasing, or evolution will be required. If an ancestor of the
       working copy is included, then the working copy itself will also be fixed,
       and the working copy will be updated to the fixed parent.
   
       When determining what lines of each file to fix at each revision, the
       whole set of revisions being fixed is considered, so that fixes to earlier
       revisions are not forgotten in later ones. The --base flag can be used to
       override this default behavior, though it is not usually desirable to do
       so.
   
   (use 'hg help -e fix' to show help for the fix extension)
   
   options ([+] can be repeated):
   
       --all            fix all non-public non-obsolete revisions
       --base REV [+]   revisions to diff against (overrides automatic selection,
                        and applies to every revision being fixed)
    -s --source REV [+] fix the specified revisions and their descendants
    -w --working-dir    fix the working directory
       --whole          always fix every line of a file
   
   (some details hidden, use --verbose to show complete help)
 
   $ hg help -e fix
   fix extension - rewrite file content in changesets or working copy
   (EXPERIMENTAL)
   
   Provides a command that runs configured tools on the contents of modified
   files, writing back any fixes to the working copy or replacing changesets.
   
   Here is an example configuration that causes 'hg fix' to apply automatic
   formatting fixes to modified lines in C++ code:
   
     [fix]
     clang-format:command=clang-format --assume-filename={rootpath}
     clang-format:linerange=--lines={first}:{last}
     clang-format:pattern=set:**.cpp or **.hpp
   
   The :command suboption forms the first part of the shell command that will be
   used to fix a file. The content of the file is passed on standard input, and
   the fixed file content is expected on standard output. Any output on standard
   error will be displayed as a warning. If the exit status is not zero, the file
   will not be affected. A placeholder warning is displayed if there is a non-
   zero exit status but no standard error output. Some values may be substituted
   into the command:
   
     {rootpath}  The path of the file being fixed, relative to the repo root
     {basename}  The name of the file being fixed, without the directory path
   
   If the :linerange suboption is set, the tool will only be run if there are
   changed lines in a file. The value of this suboption is appended to the shell
   command once for every range of changed lines in the file. Some values may be
   substituted into the command:
   
     {first}   The 1-based line number of the first line in the modified range
     {last}    The 1-based line number of the last line in the modified range
   
   Deleted sections of a file will be ignored by :linerange, because there is no
   corresponding line range in the version being fixed.
   
   By default, tools that set :linerange will only be executed if there is at
   least one changed line range. This is meant to prevent accidents like running
   a code formatter in such a way that it unexpectedly reformats the whole file.
   If such a tool needs to operate on unchanged files, it should set the
   :skipclean suboption to false.
   
   The :pattern suboption determines which files will be passed through each
   configured tool. See 'hg help patterns' for possible values. However, all
   patterns are relative to the repo root, even if that text says they are
   relative to the current working directory. If there are file arguments to 'hg
   fix', the intersection of these patterns is used.
   
   There is also a configurable limit for the maximum size of file that will be
   processed by 'hg fix':
   
     [fix]
     maxfilesize = 2MB
   
   Normally, execution of configured tools will continue after a failure
   (indicated by a non-zero exit status). It can also be configured to abort
   after the first such failure, so that no files will be affected if any tool
   fails. This abort will also cause 'hg fix' to exit with a non-zero status:
   
     [fix]
     failure = abort
   
   When multiple tools are configured to affect a file, they execute in an order
   defined by the :priority suboption. The priority suboption has a default value
   of zero for each tool. Tools are executed in order of descending priority. The
   execution order of tools with equal priority is unspecified. For example, you
   could use the 'sort' and 'head' utilities to keep only the 10 smallest numbers
   in a text file by ensuring that 'sort' runs before 'head':
   
     [fix]
     sort:command = sort -n
     head:command = head -n 10
     sort:pattern = numbers.txt
     head:pattern = numbers.txt
     sort:priority = 2
     head:priority = 1
   
   To account for changes made by each tool, the line numbers used for
   incremental formatting are recomputed before executing the next tool. So, each
   tool may see different values for the arguments added by the :linerange
   suboption.
   
   Each fixer tool is allowed to return some metadata in addition to the fixed
   file content. The metadata must be placed before the file content on stdout,
   separated from the file content by a zero byte. The metadata is parsed as a
   JSON value (so, it should be UTF-8 encoded and contain no zero bytes). A fixer
   tool is expected to produce this metadata encoding if and only if the
   :metadata suboption is true:
   
     [fix]
     tool:command = tool --prepend-json-metadata
     tool:metadata = true
   
   The metadata values are passed to hooks, which can be used to print summaries
   or perform other post-fixing work. The supported hooks are:
   
     "postfixfile"
       Run once for each file in each revision where any fixer tools made changes
       to the file content. Provides "$HG_REV" and "$HG_PATH" to identify the file,
       and "$HG_METADATA" with a map of fixer names to metadata values from fixer
       tools that affected the file. Fixer tools that didn't affect the file have a
       value of None. Only fixer tools that executed are present in the metadata.
   
     "postfix"
       Run once after all files and revisions have been handled. Provides
       "$HG_REPLACEMENTS" with information about what revisions were created and
       made obsolete. Provides a boolean "$HG_WDIRWRITTEN" to indicate whether any
       files in the working copy were updated. Provides a list "$HG_METADATA"
       mapping fixer tool names to lists of metadata values returned from
       executions that modified a file. This aggregates the same metadata
       previously passed to the "postfixfile" hook.
   
   Fixer tools are run in the repository's root directory. This allows them to
   read configuration files from the working copy, or even write to the working
   copy. The working copy is not updated to match the revision being fixed. In
   fact, several revisions may be fixed in parallel. Writes to the working copy
   are not amended into the revision being fixed; fixer tools should always write
   fixed file content back to stdout as documented above.
   
   list of commands:
   
    fix           rewrite file content in changesets or working directory
   
   (use 'hg help -v -e fix' to show built-in aliases and global options)
 
 There is no default behavior in the absence of --rev and --working-dir.
 
   $ hg init badusage
   $ cd badusage
 
   $ hg fix
   abort: no changesets specified
   (use --source or --working-dir)

   $ hg fix --whole
   abort: no changesets specified
   (use --source or --working-dir)
   [255]
   $ hg fix --base 0
   abort: no changesets specified
   (use --source or --working-dir)
   [255]
 
 Fixing a public revision isn't allowed. It should abort early enough that
 nothing happens, even to the working directory.
 
   $ printf "hello\n" > hello.whole
   $ hg commit -Aqm "hello"
   $ hg phase -r 0 --public
   $ hg fix -r 0
   abort: cannot fix public changesets
   (see 'hg help phases' for details)
   [255]
   $ hg fix -r 0 --working-dir
   abort: cannot fix public changesets
   (see 'hg help phases' for details)
   [255]
   $ hg cat -r tip hello.whole
   hello
   $ cat hello.whole
   hello
 
   $ cd ..
 
 Fixing a clean working directory should do nothing. Even the --whole flag
 shouldn't cause any clean files to be fixed. Specifying a clean file explicitly
 should only fix it if the fixer always fixes the whole file. The combination of
 an explicit filename and --whole should format the entire file regardless.
 
   $ hg init fixcleanwdir
   $ cd fixcleanwdir
 
   $ printf "hello\n" > hello.changed
   $ printf "world\n" > hello.whole
   $ hg commit -Aqm "foo"
   $ hg fix --working-dir
   $ hg diff
   $ hg fix --working-dir --whole
   $ hg diff
   $ hg fix --working-dir *
   $ cat *
   hello
   WORLD
   $ hg revert --all --no-backup
   reverting hello.whole
   $ hg fix --working-dir * --whole
   $ cat *
   HELLO
   WORLD
 
 The same ideas apply to fixing a revision, so we create a revision that doesn't
 modify either of the files in question and try fixing it. This also tests that
 we ignore a file that doesn't match any configured fixer.
 
   $ hg revert --all --no-backup
   reverting hello.changed
   reverting hello.whole
   $ printf "unimportant\n" > some.file
   $ hg commit -Aqm "some other file"
 
   $ hg fix -r .
   $ hg cat -r tip *
   hello
   world
   unimportant
   $ hg fix -r . --whole
   $ hg cat -r tip *
   hello

   $ hg fix -r . *
   $ hg cat -r tip *

   $ hg fix -r . * --whole --config experimental.evolution.allowdivergence=true

   $ hg cat -r tip *

   $ printf "modified!!!\n" > modified.whole
   $ printf "added\n" > added.whole
 
 Listing the files explicitly causes untracked files to also be fixed, but
 ignored files are still unaffected.
 
   $ hg fix --working-dir *.whole
 
   $ hg status --all
   M clean.whole
   M modified.whole
   A added.whole

 Test that incremental fixing works on files with additions, deletions, and
 changes in multiple line ranges. Note that deletions do not generally cause
 neighboring lines to be fixed, so we don't return a line range for purely
 deleted sections. In the future we should support a :deletion config that
 allows fixers to know where deletions are located.
 
   $ hg init incrementalfixedlines
   $ cd incrementalfixedlines
 
   $ printf "a\nb\nc\nd\ne\nf\ng\n" > foo.txt
   $ hg commit -Aqm "foo"
   $ printf "zz\na\nc\ndd\nee\nff\nf\ngg\n" > foo.txt
 
   $ hg --config "fix.fail:command=echo" \
   >    --config "fix.fail:linerange={first}:{last}" \
   >    --config "fix.fail:pattern=foo.txt" \
   >    fix --working-dir
   $ cat foo.txt
   1:1 4:6 8:8
 
   $ cd ..
 
 Test that --whole fixes all lines regardless of the diffs present.
 
   $ hg init wholeignoresdiffs
   $ cd wholeignoresdiffs
 
   $ printf "a\nb\nc\nd\ne\nf\ng\n" > foo.changed
   $ hg commit -Aqm "foo"
   $ printf "zz\na\nc\ndd\nee\nff\nf\ngg\n" > foo.changed
 
   $ hg fix --working-dir

 We should do nothing with symlinks, and their targets should be unaffected. Any
 other behavior would be more complicated to implement and harder to document.
 
 #if symlink
   $ hg init dontmesswithsymlinks
   $ cd dontmesswithsymlinks
 
   $ printf "hello\n" > hello.whole
   $ ln -s hello.whole hellolink
   $ hg add
   adding hello.whole
   adding hellolink
   $ hg fix --working-dir hellolink
   $ hg status
   A hello.whole
   A hellolink
 
   $ cd ..
 #endif
 
 We should allow fixers to run on binary files, even though this doesn't sound
 like a common use case. There's not much benefit to disallowing it, and users
 can add "and not binary()" to their filesets if needed. The Mercurial
 philosophy is generally to not handle binary files specially anyway.
 
   $ hg init cantouchbinaryfiles
   $ cd cantouchbinaryfiles
 
   $ printf "hello\0\n" > hello.whole
   $ hg add
   adding hello.whole
   $ hg fix --working-dir 'set:binary()'
   $ cat hello.whole
   HELLO\x00 (esc)
 
   $ cd ..
 
 We have a config for the maximum size of file we will attempt to fix. This can
 be helpful to avoid running unsuspecting fixer tools on huge inputs, which
 could happen by accident without a well considered configuration. A more
 precise configuration could use the size() fileset function if one global limit
 is undesired.
 
   $ hg init maxfilesize
   $ cd maxfilesize
 
   $ printf "this file is huge\n" > hello.whole
   $ hg add
   adding hello.whole
   $ hg --config fix.maxfilesize=10 fix --working-dir
   ignoring file larger than 10 bytes: hello.whole
   $ cat hello.whole
   this file is huge
 
   $ cd ..
 
 If we specify a file to fix, other files should be left alone, even if they
 have changes.
 
   $ hg init fixonlywhatitellyouto
   $ cd fixonlywhatitellyouto
 
   $ printf "fix me!\n" > fixme.whole
   $ printf "not me.\n" > notme.whole
   $ hg add
   adding fixme.whole
   adding notme.whole
   $ hg fix --working-dir fixme.whole
   $ cat *.whole
   FIX ME!
   not me.
 
   $ cd ..
 
 If we try to fix a missing file, we still fix other files.
 
   $ hg init fixmissingfile
   $ cd fixmissingfile
 
   $ printf "fix me!\n" > foo.whole
   $ hg add
   adding foo.whole
   $ hg fix --working-dir foo.whole bar.whole
   bar.whole: $ENOENT$
   $ cat *.whole
   FIX ME!
 
   $ cd ..
 
 Specifying a directory name should fix all its files and subdirectories.
 
   $ hg init fixdirectory
   $ cd fixdirectory
 
   $ mkdir -p dir1/dir2
   $ printf "foo\n" > foo.whole
   $ printf "bar\n" > dir1/bar.whole
   $ printf "baz\n" > dir1/dir2/baz.whole
   $ hg add
   adding dir1/bar.whole
   adding dir1/dir2/baz.whole
   adding foo.whole
   $ hg fix --working-dir dir1
   $ cat foo.whole dir1/bar.whole dir1/dir2/baz.whole
   foo
   BAR
   BAZ
 
   $ cd ..
 
 Fixing a file in the working directory that needs no fixes should not actually
 write back to the file, so for example the mtime shouldn't change.
 
   $ hg init donttouchunfixedfiles
   $ cd donttouchunfixedfiles
 
   $ printf "NO FIX NEEDED\n" > foo.whole
   $ hg add
   adding foo.whole
   $ cp -p foo.whole foo.whole.orig
   $ cp -p foo.whole.orig foo.whole
   $ sleep 2 # mtime has a resolution of one or two seconds.
   $ hg fix --working-dir
   $ f foo.whole.orig --newer foo.whole
   foo.whole.orig: newer than foo.whole
 
   $ cd ..
 
 When a fixer prints to stderr, we don't assume that it has failed. We show the
 error messages to the user, and we still let the fixer affect the file it was
 fixing if its exit code is zero. Some code formatters might emit error messages
 on stderr and nothing on stdout, which would cause us the clear the file,
 except that they also exit with a non-zero code. We show the user which fixer
 emitted the stderr, and which revision, but we assume that the fixer will print
 the filename if it is relevant (since the issue may be non-specific). There is
 also a config to abort (without affecting any files whatsoever) if we see any
 tool with a non-zero exit status.
 
   $ hg init showstderr
   $ cd showstderr
 
   $ printf "hello\n" > hello.txt
   $ hg add
   adding hello.txt
   $ cat > $TESTTMP/work.sh <<'EOF'

 Fixing the working directory and its parent revision at the same time should
 check out the replacement revision for the parent. This prevents any new
 uncommitted changes from appearing. We test this for a clean working directory
 and a dirty one. In both cases, all lines/files changed since the grandparent
 will be fixed. The grandparent is the "baserev" for both the parent and the
 working copy.
 
   $ hg init fixdotandcleanwdir
   $ cd fixdotandcleanwdir
 
   $ printf "hello\n" > hello.whole
   $ printf "world\n" > world.whole
   $ hg commit -Aqm "the parent commit"
 
   $ hg parents --template '{rev} {desc}\n'
   0 the parent commit
   $ hg fix --working-dir -r .
   $ hg parents --template '{rev} {desc}\n'
   1 the parent commit
   $ hg cat -r . *.whole
   HELLO
   WORLD
   $ cat *.whole
   HELLO
   WORLD
   $ hg status
 
   $ cd ..
 
 Same test with a dirty working copy.
 
   $ hg init fixdotanddirtywdir
   $ cd fixdotanddirtywdir
 
   $ printf "hello\n" > hello.whole
   $ printf "world\n" > world.whole
   $ hg commit -Aqm "the parent commit"
 
   $ printf "hello,\n" > hello.whole
   $ printf "world!\n" > world.whole
 
   $ hg parents --template '{rev} {desc}\n'
   0 the parent commit
   $ hg fix --working-dir -r .
   $ hg parents --template '{rev} {desc}\n'
   1 the parent commit
   $ hg cat -r . *.whole
   HELLO
   WORLD
   $ cat *.whole
   HELLO,
   WORLD!
   $ hg status
   M hello.whole
   M world.whole
 
   $ cd ..
 
 When we have a chain of commits that change mutually exclusive lines of code,
 we should be able to do incremental fixing that causes each commit in the chain
 to include fixes made to the previous commits. This prevents children from
 backing out the fixes made in their parents. A dirty working directory is
 conceptually similar to another commit in the chain.
 
   $ hg init incrementallyfixchain
   $ cd incrementallyfixchain
 
   $ cat > file.changed <<EOF
   > first
   > second
   > third
   > fourth
   > fifth
   > EOF
   $ hg commit -Aqm "the common ancestor (the baserev)"
   $ cat > file.changed <<EOF
   > first (changed)
   > second
   > third
   > fourth
   > fifth
   > EOF
   $ hg commit -Aqm "the first commit to fix"
   $ cat > file.changed <<EOF
   > first (changed)
   > second
   > third (changed)
   > fourth
   > fifth
   > EOF
   $ hg commit -Aqm "the second commit to fix"
   $ cat > file.changed <<EOF
   > first (changed)
   > second
   > third (changed)
   > fourth
   > fifth (changed)
   > EOF
 
   $ hg fix -r . -r '.^' --working-dir

 If we incrementally fix a merge commit, we should fix any lines that changed
 versus either parent. You could imagine only fixing the intersection or some
 other subset, but this is necessary if either parent is being fixed. It
 prevents us from forgetting fixes made in either parent.
 
   $ hg init incrementallyfixmergecommit
   $ cd incrementallyfixmergecommit
 
   $ printf "a\nb\nc\n" > file.changed
   $ hg commit -Aqm "ancestor"
 
   $ printf "aa\nb\nc\n" > file.changed
   $ hg commit -m "change a"
 
   $ hg checkout '.^'
   1 files updated, 0 files merged, 0 files removed, 0 files unresolved
   $ printf "a\nb\ncc\n" > file.changed
   $ hg commit -m "change c"
   created new head
 
   $ hg merge
   merging file.changed
   0 files updated, 1 files merged, 0 files removed, 0 files unresolved
   (branch merge, don't forget to commit)
   $ hg commit -m "merge"

   $ hg fix -r . --working-dir
   $ hg cat -r . file.changed

 Abort fixing revisions if there is an unfinished operation. We don't want to
 make things worse by editing files or stripping/obsoleting things. Also abort
 fixing the working directory if there are unresolved merge conflicts.
 
   $ hg init abortunresolved
   $ cd abortunresolved
 
   $ echo "foo1" > foo.whole
   $ hg commit -Aqm "foo 1"
 
   $ hg update null
   0 files updated, 0 files merged, 1 files removed, 0 files unresolved
   $ echo "foo2" > foo.whole
   $ hg commit -Aqm "foo 2"
 
   $ hg --config extensions.rebase= rebase -r 1 -d 0

   $ hg --config extensions.rebase= fix --working-dir
   abort: unresolved conflicts
   (use 'hg resolve')
   [255]
 
   $ hg --config extensions.rebase= fix -r .
   abort: rebase in progress
   (use 'hg rebase --continue', 'hg rebase --abort', or 'hg rebase --stop')

   $ cd ..
 
 When fixing a file that was renamed, we should diff against the source of the
 rename for incremental fixing and we should correctly reproduce the rename in
 the replacement revision.
 
   $ hg init fixrenamecommit
   $ cd fixrenamecommit
 
   $ printf "a\nb\nc\n" > source.changed
   $ hg commit -Aqm "source revision"
   $ hg move source.changed dest.changed
   $ printf "a\nb\ncc\n" > dest.changed
   $ hg commit -m "dest revision"
 
   $ hg fix -r .
   $ hg log -r tip --copies --template "{file_copies}\n"
   dest.changed (source.changed)
   $ hg cat -r tip dest.changed
   a
   b
   CC
 
   $ cd ..
 
 When fixing revisions that remove files we must ensure that the replacement
 actually removes the file, whereas it could accidentally leave it unchanged or
 write an empty string to it.
 
   $ hg init fixremovedfile
   $ cd fixremovedfile
 
   $ printf "foo\n" > foo.whole
   $ printf "bar\n" > bar.whole
   $ hg commit -Aqm "add files"
   $ hg remove bar.whole
   $ hg commit -m "remove file"
   $ hg status --change .
   R bar.whole
   $ hg fix -r . foo.whole
   $ hg status --change tip
   M foo.whole
   R bar.whole
 
   $ cd ..
 
 If fixing a revision finds no fixes to make, no replacement revision should be
 created.
 
   $ hg init nofixesneeded
   $ cd nofixesneeded
 
   $ printf "FOO\n" > foo.whole
   $ hg commit -Aqm "add file"
   $ hg log --template '{rev}\n'
   0
   $ hg fix -r .
   $ hg log --template '{rev}\n'
   0
 
   $ cd ..
 
 If fixing a commit reverts all the changes in the commit, we replace it with a
 commit that changes no files.
 
   $ hg init nochangesleft
   $ cd nochangesleft
 
   $ printf "FOO\n" > foo.whole
   $ hg commit -Aqm "add file"
   $ printf "foo\n" > foo.whole
   $ hg commit -m "edit file"
   $ hg status --change .
   M foo.whole
   $ hg fix -r .
   $ hg status --change tip
 
   $ cd ..
 
 If we fix a parent and child revision together, the child revision must be
 replaced if the parent is replaced, even if the diffs of the child needed no
 fixes. However, we're free to not replace revisions that need no fixes and have
 no ancestors that are replaced.
 
   $ hg init mustreplacechild
   $ cd mustreplacechild
 
   $ printf "FOO\n" > foo.whole
   $ hg commit -Aqm "add foo"
   $ printf "foo\n" > foo.whole
   $ hg commit -m "edit foo"
   $ printf "BAR\n" > bar.whole
   $ hg commit -Aqm "add bar"
 
   $ hg log --graph --template '{rev} {files}'
   @  2 bar.whole
   |
   o  1 foo.whole
   |
   o  0 foo.whole
   
   $ hg fix -r 0:2
   $ hg log --graph --template '{rev} {files}'
   o  4 bar.whole
   |
   o  3
   |
   | @  2 bar.whole
   | |
   | x  1 foo.whole
   |/
   o  0 foo.whole
   
 
   $ cd ..
 
 It's also possible that the child needs absolutely no changes, but we still
 need to replace it to update its parent. If we skipped replacing the child
 because it had no file content changes, it would become an orphan for no good
 reason.
 
   $ hg init mustreplacechildevenifnop
   $ cd mustreplacechildevenifnop
 
   $ printf "Foo\n" > foo.whole
   $ hg commit -Aqm "add a bad foo"
   $ printf "FOO\n" > foo.whole
   $ hg commit -m "add a good foo"
   $ hg fix -r . -r '.^'
   $ hg log --graph --template '{rev} {desc}'
   o  3 add a good foo
   |
   o  2 add a bad foo
   
   @  1 add a good foo
   |
   x  0 add a bad foo
   
 
   $ cd ..
 
 Similar to the case above, the child revision may become empty as a result of
 fixing its parent. We should still create an empty replacement child.
 TODO: determine how this should interact with ui.allowemptycommit given that
 the empty replacement could have children.
 
   $ hg init mustreplacechildevenifempty
   $ cd mustreplacechildevenifempty
 
   $ printf "foo\n" > foo.whole
   $ hg commit -Aqm "add foo"
   $ printf "Foo\n" > foo.whole
   $ hg commit -m "edit foo"
   $ hg fix -r . -r '.^'
   $ hg log --graph --template '{rev} {desc}\n' --stat
   o  3 edit foo
   |
   o  2 add foo
       foo.whole |  1 +
       1 files changed, 1 insertions(+), 0 deletions(-)
   
   @  1 edit foo
   |   foo.whole |  2 +-
   |   1 files changed, 1 insertions(+), 1 deletions(-)
   |
   x  0 add foo
       foo.whole |  1 +
       1 files changed, 1 insertions(+), 0 deletions(-)
   
 
   $ cd ..
 
 Fixing a secret commit should replace it with another secret commit.
 
   $ hg init fixsecretcommit
   $ cd fixsecretcommit
 
   $ printf "foo\n" > foo.whole
   $ hg commit -Aqm "add foo" --secret
   $ hg fix -r .
   $ hg log --template '{rev} {phase}\n'
   1 secret
   0 secret
 
   $ cd ..
 
 We should also preserve phase when fixing a draft commit while the user has
 their default set to secret.
 
   $ hg init respectphasesnewcommit
   $ cd respectphasesnewcommit
 
   $ printf "foo\n" > foo.whole
   $ hg commit -Aqm "add foo"
   $ hg --config phases.newcommit=secret fix -r .
   $ hg log --template '{rev} {phase}\n'
   1 draft
   0 draft
 
   $ cd ..
 
 Debug output should show what fixer commands are being subprocessed, which is
 useful for anyone trying to set up a new config.
 
   $ hg init debugoutput
   $ cd debugoutput
 
   $ printf "foo\nbar\nbaz\n" > foo.changed
   $ hg commit -Aqm "foo"
   $ printf "Foo\nbar\nBaz\n" > foo.changed
   $ hg --debug fix --working-dir
   subprocess: * $TESTTMP/uppercase.py 1-1 3-3 (glob)
 
   $ cd ..
 
 Fixing an obsolete revision can cause divergence, so we abort unless the user
 configures to allow it. This is not yet smart enough to know whether there is a
 successor, but even then it is not likely intentional or idiomatic to fix an
 obsolete revision.
 
   $ hg init abortobsoleterev
   $ cd abortobsoleterev
 
   $ printf "foo\n" > foo.changed
   $ hg commit -Aqm "foo"
   $ hg debugobsolete `hg parents --template '{node}'`
   1 new obsolescence markers
   obsoleted 1 changesets
   $ hg --hidden fix -r 0
   abort: fixing obsolete revision could cause divergence
   [255]
 
   $ hg --hidden fix -r 0 --config experimental.evolution.allowdivergence=true
   $ hg cat -r tip foo.changed
   FOO
 
   $ cd ..
 
 Test all of the available substitution values for fixer commands.
 
   $ hg init substitution
   $ cd substitution
 
   $ mkdir foo
   $ printf "hello\ngoodbye\n" > foo/bar
   $ hg add
   adding foo/bar
   $ hg --config "fix.fail:command=printf '%s\n' '{rootpath}' '{basename}'" \
   >    --config "fix.fail:linerange='{first}' '{last}'" \
   >    --config "fix.fail:pattern=foo/bar" \
   >    fix --working-dir
   $ cat foo/bar
   foo/bar
   bar
   1
   2
 
   $ cd ..
 
 The --base flag should allow picking the revisions to diff against for changed
 files and incremental line formatting.
 
   $ hg init baseflag
   $ cd baseflag
 
   $ printf "one\ntwo\n" > foo.changed
   $ printf "bar\n" > bar.changed
   $ hg commit -Aqm "first"
   $ printf "one\nTwo\n" > foo.changed
   $ hg commit -m "second"
   $ hg fix -w --base .
   $ hg status
   $ hg fix -w --base null
   $ cat foo.changed
   ONE
   TWO
   $ cat bar.changed
   BAR
 
   $ cd ..
 
 If the user asks to fix the parent of another commit, they are asking to create
 an orphan. We must respect experimental.evolution.allowunstable.
 
   $ hg init allowunstable
   $ cd allowunstable
 
   $ printf "one\n" > foo.whole
   $ hg commit -Aqm "first"
   $ printf "two\n" > foo.whole
   $ hg commit -m "second"
   $ hg --config experimental.evolution.allowunstable=False fix -r '.^'
   abort: cannot fix changeset with children
   [255]
   $ hg fix -r '.^'
   1 new orphan changesets
   $ hg cat -r 2 foo.whole
   ONE
 
   $ cd ..
 
 The --base flag affects the set of files being fixed. So while the --whole flag
 makes the base irrelevant for changed line ranges, it still changes the
 meaning and effect of the command. In this example, no files or lines are fixed
 until we specify the base, but then we do fix unchanged lines.
 
   $ hg init basewhole
   $ cd basewhole
   $ printf "foo1\n" > foo.changed
   $ hg commit -Aqm "first"
   $ printf "foo2\n" >> foo.changed
   $ printf "bar\n" > bar.changed
   $ hg commit -Aqm "second"
 
   $ hg fix --working-dir --whole
   $ cat *.changed
   bar
   foo1
   foo2
 
   $ hg fix --working-dir --base 0 --whole
   $ cat *.changed
   BAR
   FOO1
   FOO2
 
   $ cd ..
 
 The execution order of tools can be controlled. This example doesn't work if
 you sort after truncating, but the config defines the correct order while the
 definitions are out of order (which might imply the incorrect order given the
 implementation of fix). The goal is to use multiple tools to select the lowest
 5 numbers in the file.
 
   $ hg init priorityexample
   $ cd priorityexample
 
   $ cat >> .hg/hgrc <<EOF
   > [fix]
   > head:command = head -n 5
   > head:pattern = numbers.txt
   > head:priority = 1
   > sort:command = sort -n
   > sort:pattern = numbers.txt
   > sort:priority = 2
   > EOF
 
   $ printf "8\n2\n3\n6\n7\n4\n9\n5\n1\n0\n" > numbers.txt
   $ hg add -q
   $ hg fix -w
   $ cat numbers.txt
   0
   1
   2
   3
   4
 
 And of course we should be able to break this by reversing the execution order.
 Test negative priorities while we're at it.
 
   $ cat >> .hg/hgrc <<EOF
   > [fix]
   > head:priority = -1
   > sort:priority = -2
   > EOF
   $ printf "8\n2\n3\n6\n7\n4\n9\n5\n1\n0\n" > numbers.txt
   $ hg fix -w
   $ cat numbers.txt
   2
   3
   6
   7
   8
 
   $ cd ..
 
 It's possible for repeated applications of a fixer tool to create cycles in the
 generated content of a file. For example, two users with different versions of
 a code formatter might fight over the formatting when they run hg fix. In the
 absence of other changes, this means we could produce commits with the same
 hash in subsequent runs of hg fix. This is a problem unless we support
 obsolescence cycles well. We avoid this by adding an extra field to the
 successor which forces it to have a new hash. That's why this test creates
 three revisions instead of two.
 
   $ hg init cyclictool
   $ cd cyclictool
 
   $ cat >> .hg/hgrc <<EOF
   > [fix]
   > swapletters:command = tr ab ba
   > swapletters:pattern = foo
   > EOF
 
   $ echo ab > foo
   $ hg commit -Aqm foo
 
   $ hg fix -r 0
   $ hg fix -r 1
 
   $ hg cat -r 0 foo --hidden
   ab
   $ hg cat -r 1 foo --hidden
   ba
   $ hg cat -r 2 foo
   ab
 
   $ cd ..
 
 We run fixer tools in the repo root so they can look for config files or other
 important things in the working directory. This does NOT mean we are
 reconstructing a working copy of every revision being fixed; we're just giving
 the tool knowledge of the repo's location in case it can do something
 reasonable with that.
 
   $ hg init subprocesscwd
   $ cd subprocesscwd
 
   $ cat >> .hg/hgrc <<EOF
   > [fix]
   > printcwd:command = "$PYTHON" -c "import os; print(os.getcwd())"
   > printcwd:pattern = relpath:foo/bar
   > filesetpwd:command = "$PYTHON" -c "import os; print('fs: ' + os.getcwd())"
   > filesetpwd:pattern = set:**quux
   > EOF
 
   $ mkdir foo
   $ printf "bar\n" > foo/bar
   $ printf "quux\n" > quux
   $ hg commit -Aqm blah
 
   $ hg fix -w -r . foo/bar
   $ hg cat -r tip foo/bar
   $TESTTMP/subprocesscwd
   $ cat foo/bar
   $TESTTMP/subprocesscwd
 
   $ cd foo
 
   $ hg fix -w -r . bar
   $ hg cat -r tip bar ../quux
   $TESTTMP/subprocesscwd
   quux
   $ cat bar ../quux
   $TESTTMP/subprocesscwd
   quux
   $ echo modified > bar
   $ hg fix -w bar
   $ cat bar
   $TESTTMP/subprocesscwd
 
 Apparently fixing p1() and its descendants doesn't include wdir() unless
 explicitly stated.
 
   $ hg fix -r '.::'
   $ hg cat -r . ../quux
   quux
   $ hg cat -r tip ../quux
   fs: $TESTTMP/subprocesscwd
   $ cat ../quux
   quux
 
 Clean files are not fixed unless explicitly named
   $ echo 'dirty' > ../quux
 
   $ hg fix --working-dir
   $ cat ../quux
   fs: $TESTTMP/subprocesscwd
 
   $ cd ../..
 
 Tools configured without a pattern are ignored. It would be too dangerous to
 run them on all files, because this might happen while testing a configuration
 that also deletes all of the file content. There is no reasonable subset of the
 files to use as a default. Users should be explicit about what files are
 affected by a tool. This test also confirms that we don't crash when the
 pattern config is missing, and that we only warn about it once.
 
   $ hg init nopatternconfigured
   $ cd nopatternconfigured
 
   $ printf "foo" > foo
   $ printf "bar" > bar
   $ hg add -q
   $ hg fix --debug --working-dir --config "fix.nopattern:command=echo fixed"
   fixer tool has no pattern configuration: nopattern
   $ cat foo bar
   foobar (no-eol)
   $ hg fix --debug --working-dir --config "fix.nocommand:pattern=foo.bar"
   fixer tool has no command configuration: nocommand
 
   $ cd ..
 
 Tools can be disabled. Disabled tools do nothing but print a debug message.
 
   $ hg init disabled
   $ cd disabled
 
   $ printf "foo\n" > foo
   $ hg add -q
   $ hg fix --debug --working-dir --config "fix.disabled:command=echo fixed" \
   >                              --config "fix.disabled:pattern=foo" \
   >                              --config "fix.disabled:enabled=false"
   ignoring disabled fixer tool: disabled
   $ cat foo
   foo
 
   $ cd ..
 
 Test that we can configure a fixer to affect all files regardless of the cwd.
 The way we invoke matching must not prohibit this.
 
   $ hg init affectallfiles
   $ cd affectallfiles
 
   $ mkdir foo bar
   $ printf "foo" > foo/file
   $ printf "bar" > bar/file
   $ printf "baz" > baz_file
   $ hg add -q
 
   $ cd bar
   $ hg fix --working-dir --config "fix.cooltool:command=echo fixed" \
   >                      --config "fix.cooltool:pattern=glob:**"
   $ cd ..
 
   $ cat foo/file
   fixed
   $ cat bar/file
   fixed
   $ cat baz_file
   fixed
 
   $ cd ..
 
 Tools should be able to run on unchanged files, even if they set :linerange.
 This includes a corner case where deleted chunks of a file are not considered

 Test various cases around merges. We were previously dropping files if they were
 created on only the p2 side of the merge, so let's test permutations of:
 *   added, was fixed
 *   added, considered for fixing but was already good
 *   added, not considered for fixing
 *   modified, was fixed
 *   modified, considered for fixing but was already good
 *   modified, not considered for fixing
 
 Before the bug was fixed where we would drop files, this test demonstrated the
 following issues:
 *   new_in_r1.ignored, new_in_r1_already_good.changed, and
 >   mod_in_r1_already_good.changed were NOT in the manifest for the merge commit
 *   mod_in_r1.ignored had its contents from r0, NOT r1.
 
 We're also setting a named branch for every commit to demonstrate that the
 branch is kept intact and there aren't issues updating to another branch in the
 middle of fix.

 Eventually, histedit could perhaps look at `source` extra,
 in which case this test should be revisited.

 to boost performance, largefiles checks whether specified patterns are
 related to largefiles in working directory (NOT to STANDIN) or not.

   $ hg status -A a/b/c/d
   C a/b/c/d/e.large.txt

 Pushing revision #1 causes uploading entity 89e6c98d9288, which is
 shared also by largefiles b1, b2 in revision #2 and b in revision #5.
 
 Then, entity 89e6c98d9288 is not treated as "outgoing entity" at "hg
 summary" and "hg outgoing", even though files in outgoing revision #2
 and #5 refer it.

   $ hg help mq
   mq extension - manage a stack of patches
   
   This extension lets you work with a stack of patches in a Mercurial
   repository. It manages two stacks of patches - all known patches, and applied
   patches (subset of known patches).
   
   Known patches are represented as patch files in the .hg/patches directory.
   Applied patches are both patch files and changesets.
   
   Common tasks (use 'hg help COMMAND' for more details):
   
     create new patch                          qnew
     import existing patch                     qimport
   
     print patch series                        qseries
     print applied patches                     qapplied
   
     add known patch to applied stack          qpush
     remove patch from applied stack           qpop
     refresh contents of top applied patch     qrefresh
   
   By default, mq will automatically use git patches when required to avoid
   losing file mode changes, copy records, binary files or empty files creations
   or deletions. This behavior can be configured with:
   
     [mq]
     git = auto/keep/yes/no
   
   If set to 'keep', mq will obey the [diff] section configuration while
   preserving existing git patches upon qrefresh. If set to 'yes' or 'no', mq
   will override the [diff] section and always generate git or regular patches,
   possibly losing data in the second case.
   
   It may be desirable for mq changesets to be kept in the secret phase (see 'hg
   help phases'), which can be enabled with the following setting:
   
     [mq]
     secret = True
   
   You will by default be managing a patch queue named "patches". You can create
   other, independent patch queues with the 'hg qqueue' command.
   
   If the working directory contains uncommitted files, qpush, qpop and qgoto
   abort immediately. If -f/--force is used, the changes are discarded. Setting:
   
     [mq]
     keepchanges = True
   
   make them behave as if --keep-changes were passed, and non-conflicting local
   changes will be tolerated and preserved. If incompatible options such as
   -f/--force or --exact are passed, this setting is ignored.
   
   This extension used to provide a strip command. This command now lives in the
   strip extension.
   
   list of commands:
   
   Repository creation:
   
    qclone        clone main and patch repository at same time
   
   Change creation:
   
    qnew          create a new patch
    qrefresh      update the current patch
   
   Change manipulation:
   
    qfold         fold the named patches into the current patch
   
   Change organization:
   
    qapplied      print the patches already applied
    qdelete       remove patches from queue
    qfinish       move applied patches into repository history
    qgoto         push or pop patches until named patch is at top of stack
    qguard        set or print guards for a patch
    qheader       print the header of the topmost or specified patch
    qnext         print the name of the next pushable patch
    qpop          pop the current patch off the stack
    qprev         print the name of the preceding applied patch
    qpush         push the next patch onto the stack
    qqueue        manage multiple patch queues
    qrename       rename a patch
    qselect       set or print guarded patches to push
    qseries       print the entire series file
    qtop          print the name of the current patch
    qunapplied    print the patches not yet applied
   
   File content management:
   
    qdiff         diff of the current patch and subsequent modifications
   
   Change import/export:
   
    qimport       import a patch or existing changeset

   $ hg help record
   record extension - commands to interactively select changes for
   commit/qrefresh (DEPRECATED)
   
   The feature provided by this extension has been moved into core Mercurial as
   'hg commit --interactive'.
   
   (use 'hg help extensions' for information on enabling extensions)
 
 help qrecord (no record)
 
   $ hg help qrecord
   'qrecord' is provided by the following extension:
   
       record        commands to interactively select changes for commit/qrefresh
                     (DEPRECATED)
   
   (use 'hg help extensions' for information on enabling extensions)

 help record (record)
 
   $ hg help record
   hg record [OPTION]... [FILE]...
   
   interactively select changes to commit
   
       If a list of files is omitted, all changes reported by 'hg status' will be
       candidates for recording.
   
       See 'hg help dates' for a list of formats valid for -d/--date.
   
       If using the text interface (see 'hg help config'), you will be prompted
       for whether to record changes to each modified file, and for files with
       multiple changes, for each change to use. For each query, the following
       responses are possible:
   
         y - record this change
         n - skip this change
         e - edit this change manually
   
         s - skip remaining changes to this file
         f - record remaining changes to this file
   
         d - done, skip remaining changes and files
         a - record all changes to all remaining files
         q - quit, recording no changes
   
         ? - display help
   
       This command is not available when committing a merge.
   
   (use 'hg help -e record' to show help for the record extension)
   
   options ([+] can be repeated):
   
    -A --addremove           mark new/missing files as added/removed before
                             committing
       --close-branch        mark a branch head as closed
       --amend               amend the parent of the working directory
    -s --secret              use the secret phase for committing
    -e --edit                invoke editor on commit messages
    -I --include PATTERN [+] include names matching the given patterns

 Changeset d and its descendants are excluded to avoid divergence of d, which
 would occur because the successor of d (d') is also in rebaseset. As a
 consequence f (descendant of d) is left behind.

 If the rebase set has an obsolete (d) with a successor (d') outside the rebase
 set and none in destination, we still get the divergence warning.
 By allowing divergence, we can perform the rebase.

 Pull bring content, but nothing on the current branch, we should not consider
 pre-existing heads.

   What do you want to do? u

   use 'hg resolve' to retry unresolved file merges or 'hg merge --abort' to abandon
   [1]
   $ hg resolve --list
   U file1
 Because we left it as 'unresolved' the file should still exist.
   $ [ -f file1 ] || echo "File does not exist?"
 BC behavior: `hg resolve --mark` accepts that the file is still there, and
 doesn't have a problem with this situation.
   $ hg resolve --mark --config commands.resolve.mark-check=abort
   (no more unresolved files)
   $ hg resolve --list

   (no more unresolved files)
   $ hg resolve --list
   R file1
 The file is still there:

 Let's resolve the issue by deleting the file via `hg resolve`
   $ hg resolve --unmark file1

   file 'file1' was deleted in local [working copy] but was modified in other [merge rev].

   What do you want to do? d
   (no more unresolved files)
   $ hg resolve --list
   R file1
 The file is deleted:
   $ [ -f file1 ] && echo "File still exists?" || true
 Doing `hg resolve --mark` doesn't break now that the file is missing:
   $ hg resolve --mark --config commands.resolve.mark-check=abort
   (no more unresolved files)
   $ hg resolve --mark --config commands.resolve.mark-check=warn
   (no more unresolved files)
 Resurrect the file, and delete it outside of hg:
   $ hg resolve --unmark file1
   $ hg resolve file1
   file 'file1' was deleted in local [working copy] but was modified in other [merge rev].
   You can use (c)hanged version, leave (d)eleted, or leave (u)nresolved.

 For completeness, let's try that in the opposite direction (merging r2 into r1,
 instead of r1 into r2):
   $ hg update -qCr 1
   $ hg merge -r 2
   file 'file1' was deleted in other [merge rev] but was modified in local [working copy].

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

 unknown state after unshelve if and only if it was either absent or unknown

 When i shelve commit on newly created branch, make

 running unshelve --continue newly created branch
 will be preserved.

 When i unshelve resulting in merge conflicts and makes saved
 file shelvedstate looks like in previous versions in
 mercurial(without restore branch information in 7th line) i
 expect that after resolving conflicts and successfully

 restored and branch will be unchanged.

 This function splits a bit strangely primarily to avoid changing the behavior of
 the test after a bug was fixed with how split/commit --interactive handled
 `commands.commit.interactive.unified=0`: when there were no context lines,
 it kept only the last diff hunk. When running split, this meant that runsplit
 was always recording three commits, one for each diff hunk, in reverse order
 (the base commit was the last diff hunk in the file).

 Help for uncommit
 
   $ hg help uncommit
   hg uncommit [OPTION]... [FILE]...
   
   uncommit part or all of a local changeset
   
       This command undoes the effect of a local commit, returning the affected
       files to their uncommitted state. This means that files modified or
       deleted in the changeset will be left unchanged, and so will remain
       modified in the working directory.
   
       If no files are specified, the commit will be pruned, unless --keep is
       given.
   
   (use 'hg help -e uncommit' to show help for the uncommit extension)
   
   options ([+] can be repeated):
   
       --keep                     allow an empty commit after uncommitting
       --allow-dirty-working-copy allow uncommit with outstanding changes
    -n --note TEXT                store a note on uncommit
    -I --include PATTERN [+]      include names matching the given patterns
    -X --exclude PATTERN [+]      exclude names matching the given patterns
    -m --message TEXT             use text as commit message
    -l --logfile FILE             read commit message from file
    -d --date DATE                record the specified date as commit date
    -u --user USER                record the specified user as committer
    -D --currentdate              record the current date as commit date
    -U --currentuser              record the current user as committer

 Test that we abort before we warn about the hidden commit if the working
 directory is dirty
   $ echo conflict > a
   $ hg up --hidden 3
   abort: uncommitted changes
   (commit or update --clean to discard changes)

 Test that we still warn also when there are conflicts
   $ hg up -m --hidden 3

   warning: conflicts while merging a! (edit, then use 'hg resolve --mark')
   0 files updated, 0 files merged, 0 files removed, 1 files unresolved
