Yann Collet 42a22af78b fix zlibWrapper for Visual Studio 
As per https://github.com/facebook/zstd/issues/1800#issuecomment-545945050,
Visual does not support `ssize_t` type,
which is an issue for `gzread.c`.

Added a work around, suggested by @bluenlive

Note : I have not been able to confirm the problem,
so this is a blind fix.
This seems safe outside of Visual, since it is gated by _MSC_VER macro.
 2019-10-24 15:19:05 -07:00
Yann Collet 63e435dda1 improve deprecation warning macro 
fix #1488

although, curiously enough, I was never able to reproduce the issue

Yann Collet f966cd080a added documentation on DYNAMIC_BMI2 build macro 2019-10-22 17:43:09 -07:00
Yann Collet 5d5c895b18 fix initCStream_advanced() for fast strategies 
Compression ratio of fast strategies (levels 1 & 2)
was seriously reduced, due to accidental disabling of Literals compression.

Credit to @QrczakMK, which perfectly described the issue, and implementation details,
making the fix straightforward.

Example : initCStream with level 1 on synthetic sample P50 :
Before : 5,273,976 bytes
After  : 3,154,678 bytes
ZSTD_compress (for comparison) : 3,154,550

Fix #1787.

To follow : refactor the test which was supposed to catch this issue (and failed)

Yann Collet 0ee360982d improved test mode -t

Yann Collet 1e07eb4d5c clarifications on the meaning of field Block_Size 
following comments from Intel's Smita Kumar.
 2019-08-16 15:15:25 +02:00
Yann Collet 782bfb858a fixed very minor inefficiency (nbSeq==127) 
The nbSeq "short" format (1-byte)
is compatible with any value < 128.

However, the code would cautiously only accept values < 127.
This is not an error, because the general 2-bytes format
is compatible with small values < 128.
Hence the inefficiency never triggered any warning.

Spotted by Intel's Smita Kumar.

so that it's easier to determine if test fails
as a consequence of compressing a different sample.
