| * fixed #589Yann Collet2018-10-091-1/+5
| | | | | | | | | | | | | | | | 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).
| * added a test for LZ4F_compressEnd()Yann Collet2018-10-092-11/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * fixed improper hintYann Collet2018-09-281-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 warningsYann Collet2018-09-191-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
