Yann Collet 62469c9f41 fixed wrong size in pthread struct transfer 2018-06-19 20:14:03 -07:00
Yann Collet 166901dc72 reduced POOL_resize() restriction
It's not necessary to ensure that no job is ongoing.
The pool is only expanded, existing threads are preserved.
In case of error, the only option is to return NULL and terminate the thread pool anyway.

Yann Collet 066fbbfe1c make zstdmt resize its context
when nbThreads change.

Technically, it only expands.
But when instructed to use less threads,
the thread pool will limit nb of concurrent threads.

Yann Collet 4567c57199 finalized POOL_resize()
POOL_ctx* POOL_resize(POOL_ctx* ctx, size_t numThreads)

The function may fail, and returns a NULL pointer in this case.

Nick Terrell 3841dbac84 Adjust advanced parameters to source size
In the new advanced API, adjust the parameters even if they are explicitly
set. This mainly applies to the `windowLog`, and accordingly the `hashLog`
and `chainLog`, when the source size is known.

Yann Collet 6901c94cd6 avoid duplicate code comments
when a function is decribed in hist.h,
do not describe it again in hist.c
to avoid future doc synchronization issues.

Grouped debug functions into debug.h

Yann Collet 1adf84ccb7 renamed all HUF_decompress*X4*() functions into *X2
to underline they generate up to 2 symbols per decoding,
in preparation for a future *X3 variant.

Yann Collet a09af5eb6b renamed all HUF_decompress*X2*() functions into *X1
to underline they generate one symbol per decoding operation.

The new naming scheme will make it easier to introduce an *X3 variant.

Yann Collet fa41bcc2c2 grouped debug functions into debug.h
There were 2 competing set of debug functions
within zstd_internal.h and bitstream.h.
They were mostly duplicate, and required care to avoid messing with each other.

There is now a single implementation, shared by both.

Significant change :
The macro variable ZSTD_DEBUG does no longer exist,
it has been replaced by DEBUGLEVEL,
which required modifying several source files.
