Merge pull request #592 from lz4/compressEnd 
fix LZ4F_compressEnd()
 2018-10-09 15:37:55 -07:00

6902fa4892 fixed #589 
following recommendations by @raggi.

The fix is slightly different, but achieves the same goal,
and is backed by a test tool which proves that it works
(generates the error before the patch, no longer after the patch).

e07a37d712 added a test for LZ4F_compressEnd() 
which actively tries to make it write out of bound.
For this scenario to be possible,
it's necessary to set dstCapacity < LZ4F_compressBound()

When a compression operation fails,
the CCtx context is left in an undefined state,
therefore compression cannot resume.
As a consequence :
- round trip tests must be aborted, since there is nothing valid to decompress
- most users avoid this situation, by ensuring that dstCapacity >= LZ4F_compressBound()

For these reasons, this use case was poorly tested up to now.

Merge pull request #587 from lz4/hintbug 
fixed improper hint
 2018-09-28 16:58:01 -07:00
Yann Collet
21120549a7 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.

b2215f2a89 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.

6d32240b2e clarify constant MFLIMIT 
and separate it from MATCH_SAFEGUARD_DISTANCE.

While both constants have same value,
they do not seve same purpose, hence should not be confused.
