Subject: [PATCH 1/6] fast-export: drop const when storing anonymized values
Date: Wed, 22 Mar 2023 13:37:17 -0400	[thread overview]
Message-ID: <20230322173717.GA5795@coredump.intra.peff.net> (raw)
In-Reply-To: <20230322173636.GA5643@coredump.intra.peff.net>

We store anonymized values as pointers to "const char *", since they are
conceptually const to callers who use them. But they are actually
allocated strings whose memory is owned by the struct.

The ownership mismatch hasn't been a big deal since we never free() them
(they are held until the program ends), but let's switch them to "char *"
in preparation for changing that.

Since most code only accesses them via anonymize_str(), it can continue
to narrow them to "const char *" in its return value.
