849ecf3510 [zstdcli] Support xz by default when liblzma is available 2017-06-23 17:11:38 -07:00

2d4d31c18a removed gcc compilation flag -Wbad-function-cast 
It makes it more difficult to directly cast the result of a function,
requiring to store the result in an intermediate variable.
It does not necessarily help readability,
and this restriction can be difficult to overcome in some constructions,
like some macros.

also : fixed minor Visual conversion warnings in datagencli.c

a00e9599f1 removed -g from DEBUGFLAGS 
It inflates binary sizes, which is negative for the Windows build.
It also makes it impossible to check if 2 different source codes
get nonetheless compiled to the same binary,
since checksum will be different, due to integrated source code.

741e3e8314 Add $(FLAGS) when testing for zlib/lzma support. 
* If zlib/lzma isn't in the usual spot, it won't be used,
  even if `$CFLAGS` and `$LDFLAGS` add the location it is in.
* Update the test code snippets to not trigger any warnings.

201e8c8157 programs/Makefile: remove zstd-internal target 
zstd-internal was intended to be a helper target, but it doesn't help
at all, what it does in practice is a useless rebuild of zstd every time
"make zstd" is invoked.

Fixes: 030ac243a0 ("Changed Makefile to generate zstd with .gz support by default")

5eb749e734 ZSTDMT_compress() creates a single frame 
The new strategy involves cutting frame at block level.
The result is a single frame, preserving ZSTD_getDecompressedSize()

As a consequence, bench can now make a full round-trip,
since the result is compatible with ZSTD_decompress().

This strategy will not make it possible to decode the frame with multiple threads
since the exact cut between independent blocks is not known.
MT decoding needs further discussions.
