6 years agofixed improper hint
Yann Collet [Fri, 28 Sep 2018 21:57:50 +0000 (14:57 -0700)]
fixed improper hint

when LZ4F_decompress() decodes an uncompressed block,
it provides an incorrect hint for next block
when frame checksum is enabled and block checksum is not.

Impact is low : the hint is just an hint,
the decoder works whatever the amount of input provided.

But the assumption that each call to LZ4F_decompress()
would generate just one complete block if input size hint was respected
was broken by this error.

tried to clean another bunch of cppcheck warnings

so "funny" thing with cppcheck
is that no 2 versions give the same list of warnings.

On Mac, I'm using v1.81, which had all warnings fixed.
On Travis CI, it's v1.61, and it complains about a dozen more/different things.
On Linux, it's v1.72, and it finds a completely different list of a half dozen warnings.

Some of these seems to be bugs/limitations in cppcheck itself.
The TravisCI version v1.61 seems unable to understand %zu correctly, and seems to assume it means %u.
