Yann Collet 2bd6440be0 pinned down error code enum values
Note : all error codes are changed by this new version,
but it's expected to be the last change for existing codes.

Codes are now grouped by category, and receive a manually attributed value.
The objective is to guarantee that
error code values will not change in the future
when introducing new codes.
Intentionnal empty spaces and ranges are defined
in order to keep room for potential new codes.

Yann Collet 46396523c0 ZSTD_getFrameHeader : control of windowSize limits is delegated to caller
Extracting frame header is a separate operation.
It's now possible to get frame header, whatever the window size set in it.

Yann Collet 990449b89d new field : ZSTD_frameHeader.frameType
Makes frame type (zstd,skippable) detection more straighforward.
ZSTD_getFrameHeader set frameContentSize=ZSTD_CONTENTSIZE_UNKNOWN to mean "field not present"

Nick Terrell c80fc50a8d [libzstd] Fix memcpy() on potential NULL source
* `ZSTD_decompressStream_generic()` `ip` may be `NULL` for one of the calls
  to `memcpy()`
* Assert the source is not `NULL` for calls to `memcpy()` where I believe
  the source should not be `NULL`.

Yann Collet 4effccbf56 zlib_wrapper's uncompress() uses ZSTD_isFrame() for routing
more generic and safer than using own routing for magic number comparison
2017-06-02 14:27:11 -07:00
Yann Collet ae728a43b8 removed defaultCustomMem
now ZSTD_customCMem is promoted as new default.

Advantages : ZSTD_customCMem = { NULL, NULL, NULL},
so it's natural default after a memset.

ZSTD_customCMem is public constant
(defaultCustomMem was private only).

Also : makes it possible to introduce ZSTD_calloc(),
which can now default to stdlib's calloc()
when it detects system default.

Fixed zlibwrapper which depended on defaultCustomMem.

Yann Collet 25989e361c updated ZSTD_estimate?DictSize() to pass parameter byReference
resulting ?Dict object is smaller when created byReference.
Seems better than a documentation note.

Yann Collet 2e4db3e531 fixed performance regression with ZSTD_decompress() on small files
memset() was a quick fix to initialization problems,
but initialize too much space (tables, buffers)
which show up in decompression speed of ZSTD_decompress()
since it needs to recreate DCtx at each invocation.

Fixed by only initialization relevant pointers and size fields.
2017-05-24 13:15:19 -07:00
Yann Collet 11ea2f7fda Merged ZSTD_DCtx and ZSTD_DStream objects
They are now the same object.
It's recommended to keep both types in source code
as previous versions of library (<v1.3.0)
still need this differentiation.
2017-05-23 16:19:43 -07:00
Yann Collet fa3671eac7 changed ZSTD_BLOCKSIZE_ABSOLUTEMAX into ZSTD_BLOCKSIZE_MAX

Yann Collet 7101434ec9 pedantic : added one error check
