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.

7 years agoremoved ZSTD_decompressBegin() from ZSTD_initDCtx_internal()
Yann Collet [Wed, 27 Sep 2017 20:51:05 +0000 (13:51 -0700)] 
removed ZSTD_decompressBegin() from ZSTD_initDCtx_internal()

It does not feel "right" from a dependency perspective.
ZSTD_initDCtx_internal() is triggered once, on DCtx creation,
while ZSTD_decompressBegin() is invoked at the beginning of each new frame,
and is also a user-facing prototype.

Downside : a DCtx must be init before first usage !
This was always the intention by the way, and is documented as such.
This stage is automatically done within ZSTD_decompress() and variants,
and also within ZSTD_decompressStream().
Only ZSTD_decompressContinue() is impacted,
it must be preceded by a ZSTD_decompressBegin(), as detailed in doc.

A test has been fixed, to no longer rely on undocumented assumption that ZSTD_decompressBegin() is invoked during init.

Yann Collet [Wed, 27 Sep 2017 07:39:41 +0000 (00:39 -0700)] 
fixed a bug in zstreamtest

decoder output buffer would receive a wrong size.

In previous version, ZSTD_decompressStream() would blindly trust the caller that pos <= size.
In this version, this condition is actively checked,
and the function returns an error code if this condition is not respected.

This check could also be done with an assert(),
but since this is a user-facing interface, it seems better to keep this check at runtime.
