Subject: [PATCH 5/9] xdiff: drop unused parameter in def_ff()
Date: Tue, 13 Dec 2022 06:13:08 -0500 [thread overview]
Message-ID: <Y5heRPpGYD1v5Z7X@coredump.intra.peff.net> (raw)
In-Reply-To: <Y5hdvpbLpXySHFRz@coredump.intra.peff.net>
The def_ff() function is the default "find_func" for finding hunk
headers. It has never used its "priv" argument since it was introduced
in f258475a6e (Per-path attribute based hunk header selection.,
2007-07-06). But back then we used a function pointer to switch between
a caller-provided function and the default, so the two had to conform to
the same interface.
In ff2981f724 (xdiff: factor out match_func_rec(), 2016-05-28), that
pointer indirection went away in favor of code which directly calls
either of the two functions. So there's no need for def_ff() to retain
this unused parameter.
