  Using Additional Features
  """""""""""""""""""""""""
  
      Mercurial has the ability to add new features through the use of
      extensions. Extensions may add new commands, add options to existing
      commands, change the default behavior of commands, or implement hooks.
  
      To enable the "foo" extension, either shipped with Mercurial or in the
      Python search path, create an entry for it in your configuration file,
      like this:
  
        [extensions]
        foo =
  
      You may also specify the full path to an extension:
  
        [extensions]
        myfeature = ~/.hgext/myfeature.py
  
      See 'hg help config' for more information on configuration files.
  
      Extensions are not loaded by default for a variety of reasons: they can
      increase startup overhead; they may be meant for advanced usage only; they
      may provide potentially dangerous abilities (such as letting you destroy
      or modify history); they might not be ready for prime time; or they may
      alter some usual behaviors of stock Mercurial. It is thus up to the user
      to activate extensions as needed.
  
      To explicitly disable an extension enabled in a configuration file of
      broader scope, prepend its path with !:
  
        [extensions]
        # disabling extension bar residing in /path/to/extension/bar.py
        bar = !/path/to/extension/bar.py
        # ditto, but no path was supplied for extension baz
        baz = !
  
      enabled extensions:
  
       children      command to display child changesets (DEPRECATED)
       rebase        command to move sets of revisions to a different ancestor
  
      disabled extensions:
  
       acl           hooks for controlling repository access
       blackbox      log repository events to a blackbox for debugging
       bugzilla      hooks for integrating with the Bugzilla bug tracker
       censor        erase file content at a given revision
       churn         command to display statistics about repository history
       clonebundles  advertise pre-generated bundles to seed clones
       convert       import revisions from foreign VCS repositories into
                     Mercurial
       eol           automatically manage newlines in repository files
       extdiff       command to allow external programs to compare revisions
       factotum      http authentication with factotum
       gpg           commands to sign and verify changesets
       hgk           browse the repository in a graphical way
       highlight     syntax highlighting for hgweb (requires Pygments)
       histedit      interactive history editing
       keyword       expand keywords in tracked files
       largefiles    track large binary files
       mq            manage a stack of patches
       notify        hooks for sending email push notifications
       patchbomb     command to send changesets as (a series of) patch emails
       purge         command to delete untracked files from the working
                     directory
       relink        recreates hardlinks between repository clones
       schemes       extend schemes with shortcuts to repository swarms
       share         share a common history between several working directories
       shelve        save and restore changes to the working directory
       strip         strip changesets and their descendants from history
       transplant    command to transplant changesets from another branch
       win32mbcs     allow the use of MBCS paths with problematic encodings
       zeroconf      discover and advertise repositories on the local network

Verify that extension keywords appear in help templates

  $ hg help --config extensions.transplant= templating|grep transplant > /dev/null

  $ hg help diff
  hg diff [OPTION]... ([-c REV] | [-r REV1 [-r REV2]]) [FILE]...
  
  diff repository (or selected files)
  
      Show differences between revisions for the specified files.
  
      Differences between files are shown using the unified diff format.
  
      Note:
         'hg diff' may generate unexpected results for merges, as it will
         default to comparing against the working directory's first parent
         changeset if no revisions are specified.
  
      When two revision arguments are given, then changes are shown between
      those revisions. If only one revision is specified then that revision is
      compared to the working directory, and, when no revisions are specified,
      the working directory files are compared to its first parent.
  
      Alternatively you can specify -c/--change with a revision to see the
      changes in that changeset relative to its first parent.
  
      Without the -a/--text option, diff will avoid generating diffs of files it
      detects as binary. With -a, diff will generate a diff anyway, probably
      with undesirable results.
  
      Use the -g/--git option to generate diffs in the git extended diff format.
      For more information, read 'hg help diffs'.
  
      Returns 0 on success.
  
  options ([+] can be repeated):
  
   -r --rev REV [+]         revision
   -c --change REV          change made by revision
   -a --text                treat all files as text
   -g --git                 use git extended diff format
      --binary              generate binary diffs in git mode (default)
      --nodates             omit dates from diff headers
      --noprefix            omit a/ and b/ prefixes from filenames
   -p --show-function       show which function each change is in
      --reverse             produce a diff that undoes the changes
   -w --ignore-all-space    ignore white space when comparing lines
   -b --ignore-space-change ignore changes in the amount of white space
   -B --ignore-blank-lines  ignore changes whose lines are all blank
   -Z --ignore-space-at-eol ignore changes in whitespace at EOL

  $ hg help status
  hg status [OPTION]... [FILE]...
  
  aliases: st
  
  show changed files in the working directory
  
      Show status of files in the repository. If names are given, only files
      that match are shown. Files that are clean or ignored or the source of a
      copy/move operation, are not listed unless -c/--clean, -i/--ignored,
      -C/--copies or -A/--all are given. Unless options described with "show
      only ..." are given, the options -mardu are used.
  
      Option -q/--quiet hides untracked (unknown and ignored) files unless
      explicitly requested with -u/--unknown or -i/--ignored.
  
      Note:
         'hg status' may appear to disagree with diff if permissions have
         changed or a merge has occurred. The standard diff format does not
         report permission changes and diff only reports changes relative to one
         merge parent.
  
      If one revision is given, it is used as the base revision. If two
      revisions are given, the differences between them are shown. The --change
      option can also be used as a shortcut to list the changed files of a
      revision from its first parent.
  
      The codes used to show the status of files are:
  
        M = modified
        A = added
        R = removed
        C = clean
        ! = missing (deleted by non-hg command, but still tracked)
        ? = not tracked
        I = ignored
          = origin of the previous file (with --copies)
  
      Returns 0 on success.
  
  options ([+] can be repeated):
  
   -A --all                 show status of all files
   -m --modified            show only modified files
   -a --added               show only added files
   -r --removed             show only removed files
   -d --deleted             show only deleted (but tracked) files
   -c --clean               show only files without changes
   -u --unknown             show only unknown (not tracked) files
   -i --ignored             show only ignored files
   -n --no-status           hide status prefix
   -C --copies              show source of copied files
   -0 --print0              end filenames with NUL, for use with xargs
      --rev REV [+]         show difference from revision
      --change REV          list the changed files of a revision
   -I --include PATTERN [+] include names matching the given patterns
   -X --exclude PATTERN [+] exclude names matching the given patterns

  $ hg help internals.changegroups
  Changegroups
  """"""""""""
  
      Changegroups are representations of repository revlog data, specifically
      the changelog data, root/flat manifest data, treemanifest data, and
      filelogs.
  
      There are 3 versions of changegroups: "1", "2", and "3". From a high-
      level, versions "1" and "2" are almost exactly the same, with the only
      difference being an additional item in the *delta header*.  Version "3"
      adds support for revlog flags in the *delta header* and optionally
      exchanging treemanifests (enabled by setting an option on the
      "changegroup" part in the bundle2).
  
      Changegroups when not exchanging treemanifests consist of 3 logical
      segments:
  
        +---------------------------------+
        |           |          |          |
        | changeset | manifest | filelogs |
        |           |          |          |
        |           |          |          |
        +---------------------------------+
  
      When exchanging treemanifests, there are 4 logical segments:
  
        +-------------------------------------------------+
        |           |          |               |          |
        | changeset |   root   | treemanifests | filelogs |
        |           | manifest |               |          |
        |           |          |               |          |
        +-------------------------------------------------+
  
      The principle building block of each segment is a *chunk*. A *chunk* is a
      framed piece of data:
  
        +---------------------------------------+
        |           |                           |
        |  length   |           data            |
        | (4 bytes) |   (<length - 4> bytes)    |
        |           |                           |
        +---------------------------------------+
  
      All integers are big-endian signed integers. Each chunk starts with a
      32-bit integer indicating the length of the entire chunk (including the
      length field itself).
  
      There is a special case chunk that has a value of 0 for the length
      ("0x00000000"). We call this an *empty chunk*.
  
      Delta Groups
      ============
  
      A *delta group* expresses the content of a revlog as a series of deltas,
      or patches against previous revisions.
  
      Delta groups consist of 0 or more *chunks* followed by the *empty chunk*
      to signal the end of the delta group:
  
        +------------------------------------------------------------------------+
        |                |             |               |             |           |
        | chunk0 length  | chunk0 data | chunk1 length | chunk1 data |    0x0    |
        |   (4 bytes)    |  (various)  |   (4 bytes)   |  (various)  | (4 bytes) |
        |                |             |               |             |           |
        +------------------------------------------------------------------------+
  
      Each *chunk*'s data consists of the following:
  
        +---------------------------------------+
        |                        |              |
        |     delta header       |  delta data  |
        |  (various by version)  |  (various)   |
        |                        |              |
        +---------------------------------------+
  
      The *delta data* is a series of *delta*s that describe a diff from an
      existing entry (either that the recipient already has, or previously
      specified in the bundle/changegroup).
  
      The *delta header* is different between versions "1", "2", and "3" of the
      changegroup format.

        +------------------------------------------------------------------------------+
  
      The *delta data* consists of "chunklen - 4 - headerlen" bytes, which
      contain a series of *delta*s, densely packed (no separators). These deltas
      describe a diff from an existing entry (either that the recipient already
      has, or previously specified in the bundle/changegroup). The format is
      described more fully in "hg help internals.bdiff", but briefly:
  
        +---------------------------------------------------------------+
        |              |            |            |                      |
        | start offset | end offset | new length |        content       |
        |  (4 bytes)   |  (4 bytes) |  (4 bytes) | (<new length> bytes) |
        |              |            |            |                      |
        +---------------------------------------------------------------+
  
      Please note that the length field in the delta data does *not* include
      itself.
  
      In version 1, the delta is always applied against the previous node from
      the changegroup or the first parent if this is the first entry in the
      changegroup.
  
      In version 2 and up, the delta base node is encoded in the entry in the
      changegroup. This allows the delta to be expressed against any parent,
      which can result in smaller deltas and more efficient encoding of data.
  
      Changeset Segment
      =================
  
      The *changeset segment* consists of a single *delta group* holding
      changelog data. The *empty chunk* at the end of the *delta group* denotes
      the boundary to the *manifest segment*.
  
      Manifest Segment
      ================
  
      The *manifest segment* consists of a single *delta group* holding manifest
      data. If treemanifests are in use, it contains only the manifest for the
      root directory of the repository. Otherwise, it contains the entire
      manifest data. The *empty chunk* at the end of the *delta group* denotes
      the boundary to the next segment (either the *treemanifests segment* or
      the *filelogs segment*, depending on version and the request options).
  
      Treemanifests Segment
      ---------------------
  
      The *treemanifests segment* only exists in changegroup version "3", and
      only if the 'treemanifest' param is part of the bundle2 changegroup part
      (it is not possible to use changegroup version 3 outside of bundle2).
      Aside from the filenames in the *treemanifests segment* containing a
      trailing "/" character, it behaves identically to the *filelogs segment*
      (see below). The final sub-segment is followed by an *empty chunk*
      (logically, a sub-segment with filename size 0). This denotes the boundary
      to the *filelogs segment*.
  
      Filelogs Segment
      ================
  
      The *filelogs segment* consists of multiple sub-segments, each
      corresponding to an individual file whose data is being described:
  
        +--------------------------------------------------+
        |          |          |          |     |           |
        | filelog0 | filelog1 | filelog2 | ... |    0x0    |
        |          |          |          |     | (4 bytes) |
        |          |          |          |     |           |
        +--------------------------------------------------+
  
      The final filelog sub-segment is followed by an *empty chunk* (logically,
      a sub-segment with filename size 0). This denotes the end of the segment
      and of the overall changegroup.
  
      Each filelog sub-segment consists of the following:
  
        +------------------------------------------------------+
        |                 |                      |             |
        | filename length |       filename       | delta group |
        |    (4 bytes)    | (<length - 4> bytes) |  (various)  |
        |                 |                      |             |
        +------------------------------------------------------+
  
      That is, a *chunk* consisting of the filename (not terminated or padded)
      followed by N chunks constituting the *delta group* for this file. The
      *empty chunk* at the end of each *delta group* denotes the boundary to the
      next filelog sub-segment.

  $ hg help dates
  Date Formats
  """"""""""""
  
      Some commands allow the user to specify a date, e.g.:
  
      - backout, commit, import, tag: Specify the commit date.
      - log, revert, update: Select revision(s) by date.
  
      Many date formats are valid. Here are some examples:
  
      - "Wed Dec 6 13:18:29 2006" (local timezone assumed)
      - "Dec 6 13:18 -0600" (year assumed, time offset provided)
      - "Dec 6 13:18 UTC" (UTC and GMT are aliases for +0000)
      - "Dec 6" (midnight)
      - "13:18" (today assumed)
      - "3:39" (3:39AM assumed)
      - "3:39pm" (15:39)
      - "2006-12-06 13:18:29" (ISO 8601 format)
      - "2006-12-6 13:18"
      - "2006-12-6"
      - "12-6"
      - "12/6"
      - "12/6/6" (Dec 6 2006)
      - "today" (midnight)
      - "yesterday" (midnight)
      - "now" - right now
  
      Lastly, there is Mercurial's internal format:
  
      - "1165411109 0" (Wed Dec 6 13:18:29 2006 UTC)
  
      This is the internal representation format for dates. The first number is
      the number of seconds since the epoch (1970-01-01 00:00 UTC). The second
      is the offset of the local timezone, in seconds west of UTC (negative if
      the timezone is east of UTC).
  
      The log command also accepts date ranges:
  
      - "<DATE" - at or before a given date/time
      - ">DATE" - on or after a given date/time
      - "DATE to DATE" - a date range, inclusive
      - "-DAYS" - within a given number of days of today

Test section lookup

  $ hg help revset.merge
      "merge()"
        Changeset is a merge changeset.
  
  $ hg help glossary.dag
      DAG
          The repository of changesets of a distributed version control system
          (DVCS) can be described as a directed acyclic graph (DAG), consisting
          of nodes and edges, where nodes correspond to changesets and edges
          imply a parent -> child relation. This graph can be visualized by
          graphical tools such as 'hg log --graph'. In Mercurial, the DAG is
          limited by the requirement for children to have at most two parents.
  

  $ hg help hgrc.paths
      "paths"
      -------
  
      Assigns symbolic names and behavior to repositories.
  
      Options are symbolic names defining the URL or directory that is the
      location of the repository. Example:
  
        [paths]
        my_server = https://example.com/my_repo
        local_path = /home/me/repo
  
      These symbolic names can be used from the command line. To pull from
      "my_server": 'hg pull my_server'. To push to "local_path": 'hg push
      local_path'.
  
      Options containing colons (":") denote sub-options that can influence
      behavior for that specific path. Example:
  
        [paths]
        my_server = https://example.com/my_path
        my_server:pushurl = ssh://example.com/my_path
  
      The following sub-options can be defined:
  
      "pushurl"
         The URL to use for push operations. If not defined, the location
         defined by the path's main entry is used.
  
      "pushrev"
         A revset defining which revisions to push by default.
  
         When 'hg push' is executed without a "-r" argument, the revset defined
         by this sub-option is evaluated to determine what to push.
  
         For example, a value of "." will push the working directory's revision
         by default.
  
         Revsets specifying bookmarks will not result in the bookmark being
         pushed.
  
      The following special named paths exist:
  
      "default"
         The URL or directory to use when no source or remote is specified.
  
         'hg clone' will automatically define this path to the location the
         repository was cloned from.
  
      "default-push"
         (deprecated) The URL or directory for the default 'hg push' location.
         "default:pushurl" should be used instead.

  $ hg help template.files

      files(pattern)
                    All files of the current changeset matching the pattern. See
                    'hg help patterns'.

Test section lookup by translated message

str.lower() instead of encoding.lower(str) on translated message might
make message meaningless, because some encoding uses 0x41(A) - 0x5a(Z)
as the second or later byte of multi-byte character.

For example, "\x8bL\x98^" (translation of "record" in ja_JP.cp932)
contains 0x4c (L). str.lower() replaces 0x4c(L) by 0x6c(l) and this
replacement makes message meaningless.

This tests that section lookup by translated string isn't broken by
such str.lower().

  Merge Tools
  """""""""""
  
      To merge files Mercurial uses merge tools.
  
      A merge tool combines two different versions of a file into a merged file.
      Merge tools are given the two files and the greatest common ancestor of
      the two file versions, so they can determine the changes made on both
      branches.
  
      Merge tools are used both for 'hg resolve', 'hg merge', 'hg update', 'hg
      backout' and in several extensions.
  
      Usually, the merge tool tries to automatically reconcile the files by
      combining all non-overlapping changes that occurred separately in the two
      different evolutions of the same initial base file. Furthermore, some
      interactive merge programs make it easier to manually resolve conflicting
      merges, either in a graphical way, or by inserting some conflict markers.
      Mercurial does not include any interactive merge programs but relies on
      external tools for that.
  
      Available merge tools
      =====================
  
      External merge tools and their properties are configured in the merge-
      tools configuration section - see hgrc(5) - but they can often just be
      named by their executable.
  
      A merge tool is generally usable if its executable can be found on the
      system and if it can handle the merge. The executable is found if it is an
      absolute or relative executable path or the name of an application in the
      executable search path. The tool is assumed to be able to handle the merge
      if it can handle symlinks if the file is a symlink, if it can handle
      binary files if the file is binary, and if a GUI is available if the tool
      requires a GUI.
  
      There are some internal merge tools which can be used. The internal merge
      tools are:
  
      ":dump"
        Creates three versions of the files to merge, containing the contents of
        local, other and base. These files can then be used to perform a merge
        manually. If the file to be merged is named "a.txt", these files will
        accordingly be named "a.txt.local", "a.txt.other" and "a.txt.base" and
        they will be placed in the same directory as "a.txt".
  
        This implies premerge. Therefore, files aren't dumped, if premerge runs
        successfully. Use :forcedump to forcibly write files out.
  
      ":fail"
        Rather than attempting to merge files that were modified on both
        branches, it marks them as unresolved. The resolve command must be used
        to resolve these conflicts.
  
      ":forcedump"
        Creates three versions of the files as same as :dump, but omits
        premerge.
  
      ":local"
        Uses the local 'p1()' version of files as the merged version.
  
      ":merge"
        Uses the internal non-interactive simple merge algorithm for merging
        files. It will fail if there are any conflicts and leave markers in the
        partially merged file. Markers will have two sections, one for each side
        of merge.
  
      ":merge-local"
        Like :merge, but resolve all conflicts non-interactively in favor of the
        local 'p1()' changes.
  
      ":merge-other"
        Like :merge, but resolve all conflicts non-interactively in favor of the
        other 'p2()' changes.
  
      ":merge3"
        Uses the internal non-interactive simple merge algorithm for merging
        files. It will fail if there are any conflicts and leave markers in the
        partially merged file. Marker will have three sections, one from each
        side of the merge and one for the base content.
  
      ":other"
        Uses the other 'p2()' version of files as the merged version.
  
      ":prompt"
        Asks the user which of the local 'p1()' or the other 'p2()' version to
        keep as the merged version.
  
      ":tagmerge"
        Uses the internal tag merge algorithm (experimental).
  
      ":union"
        Uses the internal non-interactive simple merge algorithm for merging
        files. It will use both left and right sides for conflict regions. No
        markers are inserted.
  
      Internal tools are always available and do not require a GUI but will by
      default not handle symlinks or binary files.
  
      Choosing a merge tool
      =====================
  
      Mercurial uses these rules when deciding which merge tool to use:
  
      1. If a tool has been specified with the --tool option to merge or
         resolve, it is used.  If it is the name of a tool in the merge-tools
         configuration, its configuration is used. Otherwise the specified tool
         must be executable by the shell.
      2. If the "HGMERGE" environment variable is present, its value is used and
         must be executable by the shell.
      3. If the filename of the file to be merged matches any of the patterns in
         the merge-patterns configuration section, the first usable merge tool
         corresponding to a matching pattern is used. Here, binary capabilities
         of the merge tool are not considered.
      4. If ui.merge is set it will be considered next. If the value is not the
         name of a configured tool, the specified value is used and must be
         executable by the shell. Otherwise the named tool is used if it is
         usable.
      5. If any usable merge tools are present in the merge-tools configuration
         section, the one with the highest priority is used.
      6. If a program named "hgmerge" can be found on the system, it is used -
         but it will by default not be used for symlinks and binary files.
      7. If the file to be merged is not binary and is not a symlink, then
         internal ":merge" is used.
      8. Otherwise, ":prompt" is used.
  
      Note:
         After selecting a merge program, Mercurial will by default attempt to
         merge the files using a simple merge algorithm first. Only if it
         doesn't succeed because of conflicting changes will Mercurial actually
         execute the merge program. Whether to use the simple merge algorithm
         first can be controlled by the premerge setting of the merge tool.
         Premerge is enabled by default unless the file is binary or a symlink.
  
      See the merge-tools and ui sections of hgrc(5) for details on the
      configuration of merge tools.

Compression engines listed in `hg help bundlespec`

  $ hg help bundlespec | grep gzip
          "v1" bundles can only use the "gzip", "bzip2", and "none" compression
        An algorithm that produces smaller bundles than "gzip".
        This engine will likely produce smaller bundles than "gzip" but will be
      "gzip"
        better compression than "gzip". It also frequently yields better (?)

  <h1>Date Formats</h1>
  <p>
  Some commands allow the user to specify a date, e.g.:
  </p>
  <ul>
   <li> backout, commit, import, tag: Specify the commit date.
   <li> log, revert, update: Select revision(s) by date.
  </ul>
  <p>
  Many date formats are valid. Here are some examples:
  </p>
  <ul>
   <li> &quot;Wed Dec 6 13:18:29 2006&quot; (local timezone assumed)
   <li> &quot;Dec 6 13:18 -0600&quot; (year assumed, time offset provided)
   <li> &quot;Dec 6 13:18 UTC&quot; (UTC and GMT are aliases for +0000)
   <li> &quot;Dec 6&quot; (midnight)
   <li> &quot;13:18&quot; (today assumed)
   <li> &quot;3:39&quot; (3:39AM assumed)
   <li> &quot;3:39pm&quot; (15:39)
   <li> &quot;2006-12-06 13:18:29&quot; (ISO 8601 format)
   <li> &quot;2006-12-6 13:18&quot;
   <li> &quot;2006-12-6&quot;
   <li> &quot;12-6&quot;
   <li> &quot;12/6&quot;
   <li> &quot;12/6/6&quot; (Dec 6 2006)
   <li> &quot;today&quot; (midnight)
   <li> &quot;yesterday&quot; (midnight)
   <li> &quot;now&quot; - right now
  </ul>
  <p>
  Lastly, there is Mercurial's internal format:
  </p>
  <ul>
   <li> &quot;1165411109 0&quot; (Wed Dec 6 13:18:29 2006 UTC)
  </ul>
  <p>
  This is the internal representation format for dates. The first number
  is the number of seconds since the epoch (1970-01-01 00:00 UTC). The
  second is the offset of the local timezone, in seconds west of UTC
  (negative if the timezone is east of UTC).
  </p>
  <p>
  The log command also accepts date ranges:
  </p>
  <ul>
   <li> &quot;&lt;DATE&quot; - at or before a given date/time
   <li> &quot;&gt;DATE&quot; - on or after a given date/time
   <li> &quot;DATE to DATE&quot; - a date range, inclusive
   <li> &quot;-DAYS&quot; - within a given number of days of today
  </ul>

  <h1>Changegroups</h1>
  <p>
  Changegroups are representations of repository revlog data, specifically
  the changelog data, root/flat manifest data, treemanifest data, and
  filelogs.
  </p>
  <p>
  There are 3 versions of changegroups: &quot;1&quot;, &quot;2&quot;, and &quot;3&quot;. From a
  high-level, versions &quot;1&quot; and &quot;2&quot; are almost exactly the same, with the
  only difference being an additional item in the *delta header*.  Version
  &quot;3&quot; adds support for revlog flags in the *delta header* and optionally
  exchanging treemanifests (enabled by setting an option on the
  &quot;changegroup&quot; part in the bundle2).
  </p>
  <p>
  Changegroups when not exchanging treemanifests consist of 3 logical
  segments:
  </p>
  <pre>
  +---------------------------------+
  |           |          |          |
  | changeset | manifest | filelogs |
  |           |          |          |
  |           |          |          |
  +---------------------------------+
  </pre>
  <p>
  When exchanging treemanifests, there are 4 logical segments:
  </p>
  <pre>
  +-------------------------------------------------+
  |           |          |               |          |
  | changeset |   root   | treemanifests | filelogs |
  |           | manifest |               |          |
  |           |          |               |          |
  +-------------------------------------------------+
  </pre>
  <p>
  The principle building block of each segment is a *chunk*. A *chunk*
  is a framed piece of data:
  </p>
  <pre>
  +---------------------------------------+
  |           |                           |
  |  length   |           data            |
  | (4 bytes) |   (&lt;length - 4&gt; bytes)    |
  |           |                           |
  +---------------------------------------+
  </pre>
  <p>
  All integers are big-endian signed integers. Each chunk starts with a 32-bit
  integer indicating the length of the entire chunk (including the length field
  itself).
  </p>
  <p>
  There is a special case chunk that has a value of 0 for the length
  (&quot;0x00000000&quot;). We call this an *empty chunk*.
  </p>
  <h2>Delta Groups</h2>
  <p>
  A *delta group* expresses the content of a revlog as a series of deltas,
  or patches against previous revisions.
  </p>
  <p>
  Delta groups consist of 0 or more *chunks* followed by the *empty chunk*
  to signal the end of the delta group:
  </p>
  <pre>
  +------------------------------------------------------------------------+
  |                |             |               |             |           |
  | chunk0 length  | chunk0 data | chunk1 length | chunk1 data |    0x0    |
  |   (4 bytes)    |  (various)  |   (4 bytes)   |  (various)  | (4 bytes) |
  |                |             |               |             |           |
  +------------------------------------------------------------------------+
  </pre>
  <p>
  Each *chunk*'s data consists of the following:
  </p>
  <pre>
  +---------------------------------------+
  |                        |              |
  |     delta header       |  delta data  |
  |  (various by version)  |  (various)   |
  |                        |              |
  +---------------------------------------+
  </pre>
  <p>
  The *delta data* is a series of *delta*s that describe a diff from an existing
  entry (either that the recipient already has, or previously specified in the
  bundle/changegroup).
  </p>
  <p>
  The *delta header* is different between versions &quot;1&quot;, &quot;2&quot;, and
  &quot;3&quot; of the changegroup format.
  </p>
  <p>
  Version 1 (headerlen=80):
  </p>

  <p>
  The *delta data* consists of &quot;chunklen - 4 - headerlen&quot; bytes, which contain a
  series of *delta*s, densely packed (no separators). These deltas describe a diff
  from an existing entry (either that the recipient already has, or previously
  specified in the bundle/changegroup). The format is described more fully in
  &quot;hg help internals.bdiff&quot;, but briefly:
  </p>
  <pre>
  +---------------------------------------------------------------+
  |              |            |            |                      |
  | start offset | end offset | new length |        content       |
  |  (4 bytes)   |  (4 bytes) |  (4 bytes) | (&lt;new length&gt; bytes) |
  |              |            |            |                      |
  +---------------------------------------------------------------+
  </pre>
  <p>
  Please note that the length field in the delta data does *not* include itself.
  </p>
  <p>
  In version 1, the delta is always applied against the previous node from
  the changegroup or the first parent if this is the first entry in the
  changegroup.
  </p>
  <p>
  In version 2 and up, the delta base node is encoded in the entry in the
  changegroup. This allows the delta to be expressed against any parent,
  which can result in smaller deltas and more efficient encoding of data.
  </p>
  <h2>Changeset Segment</h2>
  <p>
  The *changeset segment* consists of a single *delta group* holding
  changelog data. The *empty chunk* at the end of the *delta group* denotes
  the boundary to the *manifest segment*.
  </p>
  <h2>Manifest Segment</h2>
  <p>
  The *manifest segment* consists of a single *delta group* holding manifest
  data. If treemanifests are in use, it contains only the manifest for the
  root directory of the repository. Otherwise, it contains the entire
  manifest data. The *empty chunk* at the end of the *delta group* denotes
  the boundary to the next segment (either the *treemanifests segment* or the
  *filelogs segment*, depending on version and the request options).
  </p>
  <h3>Treemanifests Segment</h3>
  <p>
  The *treemanifests segment* only exists in changegroup version &quot;3&quot;, and
  only if the 'treemanifest' param is part of the bundle2 changegroup part
  (it is not possible to use changegroup version 3 outside of bundle2).
  Aside from the filenames in the *treemanifests segment* containing a
  trailing &quot;/&quot; character, it behaves identically to the *filelogs segment*
  (see below). The final sub-segment is followed by an *empty chunk* (logically,
  a sub-segment with filename size 0). This denotes the boundary to the
  *filelogs segment*.
  </p>
  <h2>Filelogs Segment</h2>
  <p>
  The *filelogs segment* consists of multiple sub-segments, each
  corresponding to an individual file whose data is being described:
  </p>
  <pre>
  +--------------------------------------------------+
  |          |          |          |     |           |
  | filelog0 | filelog1 | filelog2 | ... |    0x0    |
  |          |          |          |     | (4 bytes) |
  |          |          |          |     |           |
  +--------------------------------------------------+
  </pre>
  <p>
  The final filelog sub-segment is followed by an *empty chunk* (logically,
  a sub-segment with filename size 0). This denotes the end of the segment
  and of the overall changegroup.
  </p>
  <p>
  Each filelog sub-segment consists of the following:
  </p>
  <pre>
  +------------------------------------------------------+
  |                 |                      |             |
  | filename length |       filename       | delta group |
  |    (4 bytes)    | (&lt;length - 4&gt; bytes) |  (various)  |
  |                 |                      |             |
  +------------------------------------------------------+
  </pre>
  <p>
  That is, a *chunk* consisting of the filename (not terminated or padded)
  followed by N chunks constituting the *delta group* for this file. The
  *empty chunk* at the end of each *delta group* denotes the boundary to the
  next filelog sub-segment.
