[libzstd] Set CLEVEL_CUSTOM correctly
2017-10-02 14:51:47 -07:00
Nick Terrell 86e83e926f [libzstd] Set CLEVEL_CUSTOM correctly
In `ZSTD_compressBegin_advanced()`, `ZSTD_parameters` are used to set the
compression parameters, but the level didn't get set to `CLEVEL_CUSTOM`, so
`ZSTD_compressBlock()` used the wrong parameters when checking the source
size.

Nick Terrell c5d6dde502 Don't `size -= 1` in ZSTD_adjustCParams()
The window size could end up too small if the source size is 2^n + 1.

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.

Yann Collet 8afb151c9b cli: fixed wrong initialization in MT mode
It's not good to mix old and new API
ZSTD_resetCStream() doesn't just set pledgedSrcSize :
it also sets the CCtx for a single thread compression.

Problem is, when 2+ threads are defined in cctx->requestedParams,
ZSTD_compress_generic() will want to start MT compression,
since initialization is supposed to have already happened (thanks to ZSTD_resetCStream())
except that the underlying ZSTDMT_CCtx* object is not created,
resulting in a segfault.

This is an invalid construction
(correct one is to use ZSTD_CCtx_setPledgedSrcSize()).
I haven't found a nice way to mitigate this impact if someone makes the same mistake.

At some point, removing the old API to keep only the new API within fileio.c will limit these risks.

Yann Collet fbd5ab7027 minor fix : no longer use fake srcSize during resource creation
srcSize is read and provided at each file, not at resource creation.
This used to be useful with older API, because it could not re-adapt parameters between sessions.

At some point, it will be better to remove the old code, and only keep the new_api.
It works fine by now.

Yann Collet db1668a43b fix : srcSize written in frame header when multiple files compressed
This information used to be disabled when nbFiles>1.
It was badly initialized later in the code, resulting in an error.

Yann Collet 1416bc0f07 erase existence of a buffer when it's sent out of the pool
In some complex scenario,
the buffer would be freed because it's too large,
another buffer would be allocated, but fail,
trigger an error,
and the general buffer pool would then be freed,
where the definition of the already freed buffer would be found
(beyond total index, but still), and freed again, resulting in double-free error.

Yann Collet 8afcc80e07 decode more data before triggering error
fixes #874 :
when a frame is not properly terminated by a "last block" signal,
zstd -d used to detect it immediately and error out.
This version will decode and flush the last block, and only then issue an error.

Yann Collet e963800e27 zstdmt : fixed : buffer dst0 wasn't properly set to null after usage

wether previous compression was completed correctly or not.
