Subject: [PATCH 6/7] lib: new testcases for bitmap_parse{_user}
Date: Sun, 8 Sep 2019 20:30:20 -0700 [thread overview]
Message-ID: <20190909033021.11600-7-yury.norov@gmail.com> (raw)
In-Reply-To: <20190909033021.11600-1-yury.norov@gmail.com>
New version of bitmap_parse() is unified with bitmap_parse_list(),
and therefore:
- weakens rules on whitespaces and commas between hex chunks;
- in addition to \0 allows using \n as the line ending symbol;
- allows passing UINT_MAX or any other big number as the length
of input string instead of actual string length.
The patch covers the cases.
