This is a standalone function to allow extensions to wrap it.
Because we use the set of immutable changesets as a fallback subset in
branchmap (see mercurial.utils.repoviewutils.subsettable), you cannot set
"public" changesets as "hideable". Doing so would break multiple code
assertions and lead to crashes.s obsolete)r �getrevs� _phasecache� getrevsetr �localhiddenphases� frozenset)�repo� obsoletes� internals� r �4/usr/lib/python3/dist-packages/mercurial/repoview.py� hideablerevs# s r c s� | j � t� }|�dd� | d �� D �� |�� fdd�| j�� D �� i }t�| j| |i � |rG� j j

The immutable filter still have some chance to get invalidated. This will
happen when:
- you garbage collect hidden changeset,
- public phase is moved backward,
- something is changed in the filtering (this could be fixed)
This filter out any mutable changeset and any public changeset that may be
impacted by something happening to a mutable revision.
This is achieved by filtered everything with a revision number equal or
higher than the first mutable changeset is filtered.c 3 s � | ]}� � |�V qd S rX r )r �rr" r r r& � s � z$computeimpactable.<locals>.<genexpr>r )

This returns a version of 'revs' to be used thereafter by the caller.
In particular, if revs is an iterator, it is converted into a set.

dd� Z dd� Z dS )�repoviewa� Provide a read/write view of a repo through a filtered changelog
This object is used to access a filtered version of a repository without
altering the original repository object itself. We can not alter the
original object for two main reasons:
- It prevents the use of a repo with multiple filters at the same time. In
particular when multiple threads are involved.
- It makes scope of the filtering harder to control.
This object behaves very closely to the original repository. All attribute
operations are done on the original repository:
- An access to `repoview.someattr` actually returns `repo.someattr`,
- A write to `repoview.someattr` actually sets value of `repo.someattr`,
- A deletion of `repoview.someattr` actually drops `someattr`
from `repo.__dict__`.
The only exception is the `changelog` property. It is overridden to return
a (surface) copy of `repo.changelog` with some revisions filtered. The
`filtername` attribute of the view control the revisions that need to be
filtered. (the fact the changelog is copied is an implementation detail).
Unlike attributes, this object intercepts all method calls. This means that
all methods are run on the `repoview` object with the filtered `changelog`
property. For this purpose the simple `repoview` class must be mixed with
the actual class of the repository. This ensures that the resulting
`repoview` object have the very same methods than the repo object. This
leads to the property below.
repoview.method() --> repo.__class__.method(repoview)
The inheritance has to be done dynamically because `repo` can be of any
subclasses of `localrepo`. Eg: `bundlerepo` or `statichttprepo`.
