* created LZ4_initStreamHC()Yann Collet2019-04-051-21/+21
| | | | | | | | - promoted LZ4_resetStreamHC_fast() to stable - moved LZ4_resetStreamHC() to deprecated (but do not generate a warning yet) - Updated doc, to highlight difference between init and reset - switched all invocations of LZ4_resetStreamHC() onto LZ4_initStreamHC() - misc: ensure `make all` also builds /tests

| * fuzzer.c: enabled ring buffer tests for decompress_fastAlexey Tourbin2018-04-271-40/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | Ring buffer tests were performed only with LZ4_decompress_safe_continue, leaving my buggy changes to LZ4_decompress_safe_continue undetected. The tests are now replicated and performed in a similar manner for both LZ4_decompress_safe_continue and LZ4_decompress_safe_continue (except for the small buffer case where only one function can be tested, because part of the dictionary is overwritten with the output). I also updated function names in the messages (changed them to the actual ones). The error was reported for LZ4_decompress_safe(), which I found misleading.

* | Fix input size validation edge casesNick Terrell2018-04-231-0/+26
|/ | | | | | | | | | | | | | | | | The bug is a read up to 2 bytes past the end of the buffer. There are three cases for this bug, one for each test case added. * An empty input causes `token = *ip++` to read one byte too far. * A one byte input with `(token >> ML_BITS) == RUN_MASK` causes one extra byte to be read without validation. This could be combined with the first bug to cause 2 extra bytes to be read. * The case pointed out in issue #508, where `ip == iend` at the beginning of the loop after taking the shortcut. Benchmarks show no regressions on clang or gcc-7 on both my mac and devserver. Fixes #508.
