Subject: [PATCH 5/5] trailer: rename *_DEFAULT enums to *_UNSPECIFIED
Date: Sat, 05 Aug 2023 05:04:39 +0000 [thread overview]
Message-ID: <7c9b63c26164b037272fde689bb3150b30aa7528.1691211879.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1563.git.1691211879.gitgitgadget@gmail.com>
From: Linus Arver <linusa@google.com>
Do not use *_DEFAULT as a suffix to the enums, because the word
"default" is overloaded. The following are two examples of the ambiguity
of the word "default":
(1) "Default" can mean using the "default" values that are hardcoded
in trailer.c as
default_conf_info.where = WHERE_END;
default_conf_info.if_exists = EXISTS_ADD_IF_DIFFERENT_NEIGHBOR;
default_conf_info.if_missing = MISSING_ADD;
in ensure_configured(). These values are referred to as "the
default" in the docs for interpret-trailers. These defaults are used
if no "trailer.*" configurations are defined.
(2) "Default" can also mean the "trailer.*" configurations themselves,
because these configurations are used by "default" (ahead of the
hardcoded defaults in (1)) if no command line arguments are
provided.
In addition, the corresponding *_DEFAULT values are chosen when the user
provides the "--no-where", "--no-if-exists", or "--no-if-missing" flags
on the command line. These "--no-*" flags are used to clear previously
provided flags of the form "--where", "--if-exists", and "--if-missing".
Using these "--no-*" flags undoes the specifying of these flags (if
any), so using the word "UNSPECIFIED" is more natural here.
So instead of using "*_DEFAULT", use "*_UNSPECIFIED" because this
signals to the reader that the *_UNSPECIFIED value by itself carries no
meaning (it's a zero value and by itself does not "default" to anything,
necessitating the need to have some other way of getting to a useful
value).
