535636ff5c Don't Attach Very Small Dictionaries 
Fixes a mismatch in behavior between loading into the context (via
`LZ4_loadDict()`) a very small (<= 4 bytes) non-contiguous dictionary, versus
attaching it with `LZ4_attach_dictionary()`.

Before this patch, this divergence could be reproduced by running

```
make -C tests fuzzer MOREFLAGS="-m32"
tests/fuzzer -v -s1239 -t3146
```

Making sure these two paths behave exactly identically is an easy way to test
the correctness of the attach path, so it's desirable that this remain an
unpolluted, high signal test.

fix LZ4F_compressEnd()

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.

Rename initCheck to dirtyContext and use it in LZ4_resetStream_fast()
 2018-09-28 15:58:22 -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.
