+
+  This is an advanced option that non-admin users should not need to understand
+  or set. This option can be used to speed up pulls from trusted central
+  servers, or to fix-up deltas from older servers.
+
+  It supports the following values:
+
+  - ``default``: use the policy defined by
+    `storage.revlog.reuse-external-delta-parent`,
+
+  - ``no-reuse``: start a new optimal delta search for each new revision we add
+    to the repository. The deltas from the server will be reused when the base
+    it applies to is tested (this can be frequent if that base is the one and
+    unique parent of that revision). This can significantly slowdown pulls but
+    will result in an optimized storage space if the remote peer is sending poor
+    quality deltas.
+
+  - ``try-base``: try to reuse the deltas from the remote peer as long as they
+    create a valid delta-chain in the local repository. This speeds up the
+    unbundling process, but can result in sub-optimal storage space if the
+    remote peer is sending poor quality deltas.
+
+  - ``forced``: the deltas from the peer will be reused in all cases, even if
+    the resulting delta-chain is "invalid". This setting will ensure the bundle
+    is applied at minimal CPU cost, but it can result in longer delta chains
+    being created on the client, making revisions potentially slower to access
+    in the future. If you think you need this option, you should make sure you
+    are also talking to the Mercurial developer community to get confirmation.
+
+  See `hg help config.storage.revlog.reuse-external-delta-parent` for a similar
+  global option. That option defines the behavior of `default`.

         because you can't (e.g. if you want to add ``__repr__`` methods to
         Django models) or don't want to.
 
         If *these* is not ``None``, ``attrs`` will *not* search the class body

         to automatically detect that.  Therefore it's possible to set the

+        arguments is implemented in the *current* class (i.e. it is *not*
+        inherited from some base class).
+
+        So for example by implementing ``__eq__`` on a class yourself,
+        ``attrs`` will deduce ``eq=False`` and will create *neither*
+        ``__eq__`` *nor* ``__ne__`` (but Python classes come with a sensible
+        ``__ne__`` by default, so it *should* be enough to only implement

+
+           If you prevent ``attrs`` from creating the ordering methods for you

+           *your* responsibility to make sure its ordering is sound. The best
+           way is to use the `functools.total_ordering` decorator.
+
+
+        Passing ``True`` or ``False`` to *init*, *repr*, *eq*, *order*,
+        *cmp*, or *hash* overrides whatever *auto_detect* would determine.

+          methods. It just won't add own ones.),
+        - all attributes that are either passed into ``__init__`` or have a
+          default value are additionally available as a tuple in the ``args``
+          attribute,
+        - the value of *str* is ignored leaving ``__str__`` to base classes.
+    :param bool collect_by_mro: Setting this to `True` fixes the way ``attrs``
+       collects attributes from base classes.  The default behavior is
+       incorrect in certain cases of multiple inheritance.  It should be on by
+       default but is kept off for backward-compatibility.
+
+       See issue `#428 <https://github.com/python-attrs/attrs/issues/428>`_ for
+       more details.
+
+    :param Optional[bool] getstate_setstate:
+       .. note::
+          This is usually only interesting for slotted classes and you should
+          probably just set *auto_detect* to `True`.
+
+       If `True`, ``__getstate__`` and
+       ``__setstate__`` are generated and attached to the class. This is
+       necessary for slotted classes to be pickleable. If left `None`, it's
+       `True` by default for slotted classes and ``False`` for dict classes.
+
+       If *auto_detect* is `True`, and *getstate_setstate* is left `None`,
+       and **either** ``__getstate__`` or ``__setstate__`` is detected directly
+       on the class (i.e. not inherited), it is set to `False` (this is usually
+       what you want).
+
+    :param on_setattr: A callable that is run whenever the user attempts to set
+        an attribute (either by assignment like ``i.x = 42`` or by using
+        `setattr` like ``setattr(i, "x", 42)``). It receives the same arguments
+        as validators: the instance, the attribute that is being modified, and
+        the new value.
+
+        If no exception is raised, the attribute is set to the return value of
+        the callable.
+
+        If a list of callables is passed, they're automatically wrapped in an
+        `attrs.setters.pipe`.
+    :type on_setattr: `callable`, or a list of callables, or `None`, or
+        `attrs.setters.NO_OP`
+
+    :param Optional[callable] field_transformer:
+        A function that is called with the original class object and all
+        fields right before ``attrs`` finalizes the class.  You can use
+        this, e.g., to automatically add converters or validators to
+        fields based on their types.  See `transform-fields` for more details.
+
+    :param bool match_args:
+        If `True` (default), set ``__match_args__`` on the class to support
+        :pep:`634` (Structural Pattern Matching). It is a tuple of all
+        non-keyword-only ``__init__`` parameter names on Python 3.10 and later.
+        Ignored on older Python versions.

+Case where we force a "bad" delta to be applied
+===============================================
+
+We build a very different file content to force a full snapshot
+

+  $ cp -ar local-pre-pull local-pre-pull-full

+  > | $PYTHON $TESTTMP/sha256line.py > peer-bad-delta-with-full/my-file.txt

+
+Check that "try-base" behavior challenge the delta
+--------------------------------------------------
+
+The bundling process creates a delta against the previous revision, however this
+is an invalid chain for the client, so it is not considered and we do a full
+snapshot again.
+
+  $ cp -ar local-pre-pull-full local-try-base-full
+  $ hg -R local-try-base-full pull --quiet \
+  > --config 'paths.default:delta-reuse-policy=try-base'

+
+Check that "forced" behavior do not challenge the delta, even if it is full.
+---------------------------------------------------------------------------
+
+A full bundle should be accepted as full bundle without recomputation
+
+  $ cp -ar local-pre-pull-full local-forced-full
+  $ hg -R local-forced-full pull --quiet \
+  > --config 'paths.default:delta-reuse-policy=forced'

+
+Check that "forced" behavior do not challenge the delta, even if it is bad.
+---------------------------------------------------------------------------
+
+The client does not challenge anything and applies the bizarre delta directly.
+
+Note: If the bundling process becomes smarter, this test might no longer work
+(as the server won't be sending "bad" deltas anymore) and might need something
+more subtle to test this behavior.
