Yann Collet 61e5a1adfc removed direct call to malloc() from pool.c 2017-10-31 17:43:24 -07:00
Nick Terrell a86a7097ec Ensure dictionary Huff table can encode any symbol 
* Ensure that the dictionary Huffman CTable has maxSymbolValue 255.
* Fix a stack buffer overflow during compression dictionary loading.

Yann Collet ee1ed78fcb fix proper naming on FSE_createCTable() arguments in fse.h 2017-09-30 11:08:50 -07:00
Yann Collet 86b4fe5b45 adjustCParams : restored previous behavior 
unknowns srcSize presumed small if there is a dictionary (dictSize>0)
and presumed large otherwise.

Nick Terrell 6c41adfb28 [libzstd] pthread function prefixed with ZSTD_ 
* `sed -i 's/pthread_/ZSTD_pthread_/g' lib/{,common,compress,decompress,dictBuilder}/*.[hc]`
* Fix up `lib/common/threading.[hc]`
* `sed -i s/PTHREAD_MUTEX_LOCK/ZSTD_PTHREAD_MUTEX_LOCK/g lib/compress/zstdmt_compress.c`

Yann Collet 9416195221 changed error code when pos<=size condition is not respected 
Now pointing towards src_size or dst_size,
instead of error_GENERIC.

Yann Collet 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

Yann Collet 9f0b8dfbe9 Merge branch 'dev' into newFormats 2017-09-26 14:22:39 -07:00
Nick Terrell 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.

Yann ColletandGitHub 5d8fdd1641 Merge pull request #855 from terrelln/maxoff 
[libzstd] Increase MaxOff
 2017-09-25 16:34:29 -07:00
Yann Collet 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.
