To achieve this, we need a little extra plumbing, which we start adding here. diff --git a/mercurial/error.py b/mercurial/error.py --- a/mercurial/error.py +++ b/mercurial/error.py @@ -122,6 +122,12 @@ class CapabilityError(RepoError): class RequirementError(RepoError): """Exception raised if .hg/requires has an unknown entry.""" +class StdioError(IOError): + """Raised if I/O to stdout or stderr fails""" + + def __init__(self, err): + IOError.__init__(self, err.errno, err.strerror) + class UnsupportedMergeRecords(Abort): def __init__(self, recordtypes): from .i18n import _ _______________________________________________ Mercurial-devel mailing list Mercurial-devel@mercurial-scm.org https://www.mercurial-scm.org/mailman/listinfo/mercurial-devel
