bundlerepo: disable filtering of changelog while constructing revision text This avoids the following error that happened if base revision of bundle file was hidden. bundlerevlog needs it to construct revision texts from bundle content as revlog.revision() does. File "mercurial/context.py", line 485, in _changeset return self._repo.changelog.read(self.rev()) File "mercurial/changelog.py", line 319, in read text = self.revision(node) File "mercurial/bundlerepo.py", line 124, in revision text = self.baserevision(iterrev) File "mercurial/bundlerepo.py", line 160, in baserevision return changelog.changelog.revision(self, nodeorrev) File "mercurial/revlog.py", line 1041, in revision node = self.node(rev) File "mercurial/changelog.py", line 211, in node raise error.FilteredIndexError(rev) mercurial.error.FilteredIndexError: 1
