1fd621ff6d minor man page update 
regarding advanced parameter `tlen`
which was recently changed.
`0` in association with `ZSTD_fast` now means "normal fast mode".

Correct multithread logic, fixing 'unsupported parameter' error 
The original conditions only worked, when both, static and shared variants where built, resulting in an inconsistency between programs and library. The program was built with MT support enabled, the library not. That lead to error 11 'unsupported parameter' when compressing anything with the command line tool.

When changing the AND condition to `ZSTD_MULTITHREAD_SUPPORT AND (ZSTD_BUILD_SHARED OR ZSTD_BUILD_SHARED)`, cmake stopps complaining one of the targets wasn't built. This commit works for any case.

[zstdmt] Fix jobsize bugs (#1205) 
[zstdmt] Fix jobsize bugs

* `ZSTDMT_serialState_reset()` should use `targetSectionSize`, not `jobSize` when sizing the seqstore.
  Add an assert that checks that we sized the seqstore using the right job size.
* `ZSTDMT_compressionJob()` should check if `rawSeqStore.seq == NULL`.
* `ZSTDMT_initCStream_internal()` should not adjust `mtctx->params.jobSize` (clamping to MIN/MAX is okay).

Merge pull request #1204 from facebook/noForwardProgress 
Error code on no forward progress
 2018-06-22 20:25:29 -07:00
Yann Collet
31769ce702 error on no forward progress 
streaming decoders, such as ZSTD_decompressStream() or ZSTD_decompress_generic(),
may end up making no forward progress,
(aka no byte read from input __and__ no byte written to output),
due to unusual parameters conditions,
such as providing an output buffer already full.

In such case, the caller may be caught in an infinite loop,
calling the streaming decompression function again and again,
without making any progress.

This version detects such situation, and generates an error instead :
ZSTD_error_dstSize_tooSmall when output buffer is full,
ZSTD_error_srcSize_wrong when input buffer is empty.

The detection tolerates a number of attempts before triggering an error,
controlled by ZSTD_NO_FORWARD_PROGRESS_MAX macro constant,
which is set to 16 by default, and can be re-defined at compilation time.
This behavior tolerates potentially existing implementations
where such cases happen sporadically, like once or twice,
which is not dangerous (only infinite loops are),
without generating an error, hence without breaking these implementations.

Thread Pool resize

fbd5dfc1b1 changed POOL_resize() return type to int 
return is now just en error code.
This guarantee that `ctx` remains valid after POOL_resize().
Gets rid of internal POOL_free() operation.
