bb5c34a875 bumped version number to v1.9.2 
to reduce risks that future bug reports in `dev` branch report `v1.9.1` as the failing version.

1d759576b9 precise again that LZ4 decoder needs metadata 
and that such metadata must be provided / sent / saved by the application.

bcb26565a7 improved documentation for LZ4 dictionary compression 2019-04-11 15:20:46 -07:00

8d76c8a44a introduce LZ4_DISTANCE_MAX build macro 
make it possible to generate LZ4-compressed block
with a controlled maximum offset (necessarily <= 65535).

This could be useful for compatibility with decoders
using a very limited memory budget (<64 KB).

14c71dfa9c modified LZ4_initStreamHC() to look like LZ4_initStream() 
it is now a pure initializer, for statically allocated states.
It can initialize any memory area, and because of this, requires size.

2ece0d8380 created LZ4_initStream() 
- promoted LZ4_resetStream_fast() to stable
- moved LZ4_resetStream() into deprecate, but without triggering a compiler warning
- update all sources to no longer rely on LZ4_resetStream()

note : LZ4_initStream() proposal is slightly different :
it's able to initialize any buffer, provided that it's large enough.
To this end, it accepts a void*, and returns an LZ4_stream_t*.

a803230f67 unpublish static-only function 
these functions are now unpublished in dll by default.
One needs to opt-in, using macro LZ4_PUBLISH_STATIC_FUNCTIONS.

c25eb16666 random lz4f clarifications 
the initial intention was to update lz4f ring buffer strategy,
but lz4f doesn't use ring buffer.
Instead, it uses the destination buffer as much as possible,
and merely copies just what's required to preserve history
into its own buffer, at the end.
Pretty efficient.

This patch just clarifies a few comments and add some assert().
It's built on top of #528.

It also updates doc.

57afa36795 compatibility with gcc-4.4 string.h version 
Someone found it would be a great idea to define there a global variable under the very generic name "index".
Cause problem with shadow warnings, so no variable can be named "index" now ...

Also : automatically update API manual
