76ac0b2d99 macro compatible with scenario where windowSize = 1024 (minimum) 2017-09-30 15:34:44 -07:00
Yann Collet
5b10345b26 added ZSTD_COMPRESSBOUND() as a macro 
ZSTD_compressBound() works fine, but is only useful for dynamic allocation.
For static allocation, only a macro can provide the amount during compilation time.

9b5b47ac93 ensure adjustCParams adjust hLog and cLog even without srcSize 
It would previously exit when srcSize is unknown.
But in the case of custom parameters,
hLog and cLog can still be too large in comparison with windowLog.

Reduces maximum memory allocated during zstreamtest --newapi

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().

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.

058ed2ad33 ZSTD_decodingBufferSize_min() 
supporting function for bufferless streaming API (ZSTD_decompressContinue())
makes it possible to correctly size a round buffer for decoding using this API.

also : added field blockSizeMax within ZSTD_frameHeader,
as it's a necessary information to know when to restart at beginning of decoding buffer.
