changeset 4327:8967698f6b53

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
(UTILS_FUNC_DIRFD): Test the cache variable, not one that is guaranteed to be `no'. Use `no_such_member' to indicate that condition, rather than `-1' which is slightly misleading. Change the name of the cache variable to have the gl_ prefix. Prompted by a patch from Richard Dawe for DJGPP.
