[fuzz] Speed up round trip tests
 2017-09-26 14:57:24 -07:00

df4e9bba25 fixed constant errors for gcc in c99 mode 
C standard does not consider a `static const int` as a constant.
This is a problem for initializer, and ZSTD_STATIC_ASSERT().
Replaced by macro values

471aa385b3 [fuzz] Speed up round trip tests 
* Enforce smaller maximum values for parameters
* Adjust parameters to the source size

The memory usage is reduced by about 5x, which makes the fuzzers run at
least twice as fast, even more so with ASAN/MSAN enabled.

c233bdbaee Increase maximum window size 
* Maximum window size in 32-bit mode is 1GB, since allocations for 2GB fail
  on my Mac.
* Maximum window size in 64-bit mode is 2GB, since that is the largest
  power of 2 that works with the overflow prevention.
* Allow `--long=windowLog` to set the window log, along with
  `--zstd=wlog=#`. These options also set the window size during
  decompression, but don't override `--memory=#` if it is set.
* Present a helpful error message when the window size is too large during
  decompression.
* The long range matcher defaults to a hash log 7 less than the window log,
  which keeps it at 20 for window log 27.
* Keep the default long range matcher window size and the default maximum
  window size at 27 for the API and CLI.
* Add tests that use the maximum window size and hash size for compression
  and decompression.

76cb38d085 [zstd] Backport kernel patch from @ColinIanKing 
* Make the U32 table in `FSE_normalizeCount()` static.
* Patch from https://lkml.kernel.org/r/20170922145946.14316-1-colin.king@canonical.com.
* Clang makes non-static tables static anyways. gcc however, does [weird things](https://godbolt.org/g/fvTcED).
* Benchmarks showed no difference in speed.

6ee05a02b8 added ZSTD_decompress_generic() 
same as ZSTD_decompressStream(),
just for a similar feeling as the compression side, which uses ZSTD_compress_generic()

b8d4a3887f introduced constant ZSTD_frameIdSize 
within zstd_internal.h
This is the size of magic number.

Avoids using `4` directly in source code, which is a bit less meaningful.

Simple makefile change + quick typename change

Test:

  make clean
  make
  # successfully produces binary without lz4 support

  make clean
  # with flags to pick up my lz4 build
  make MOREFLAGS="-L/home/felixh/prog/lz4/lib -I/home/felixh/prog/lz4/lib"
  # successfully produces binary with lz4 support

  echo "TEST TEST TEST THIS IS A TEST STRING PLEASE TEST THIS PLEASE OK THANK YOU" | \
    ./lz4/lz4 | \
    LD_LIBRARY_PATH=/home/felixh/prog/lz4/lib ./zstd/zstd -d
  # successfully prints TEST TEST TEST THIS IS A TEST STRING PLEASE TEST THIS PLEASE OK THANK YOU

18442a31ff [libzstd] Fix bad window size assert 
The window size is not validated or used in the one-pass API, so there
