Merge pull request #666 from lz4/blockIndep 
added command -BI for "Independent Blocks"
 2019-04-12 14:28:44 -07:00
Yann Collet
20c2a5fc94 added command -BI for "Independent Blocks" 
This is the reverse of `-BD`, and the current default.

This command can be useful to reverse a previous `-BD` command.
It may in the future be more important
if `lz4` switches to generating dependent blocks by default.

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

aka distance from end of block for the last match.

 2019-04-09 14:00:30 -07:00
Yann Collet
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.

5ef4f3ce91 check some more initialization result 
ensure it's not NULL.

111df0fa45 removed LZ4_stream_t alignment test on Visual 
it fails on x86 32-bit mode :
Visual reports an alignment of 8-bytes (even with alignof())
but actually only align LZ4_stream_t on 4 bytes.
The alignment check then fails, resulting in missed initialization.

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*.

c491df54ec created LZ4_initStreamHC() 
- promoted LZ4_resetStreamHC_fast() to stable
- moved LZ4_resetStreamHC() to deprecated (but do not generate a warning yet)
- Updated doc, to highlight difference between init and reset
- switched all invocations of LZ4_resetStreamHC() onto LZ4_initStreamHC()
- misc: ensure `make all` also builds /tests

Merge pull request #657 from lz4/destSize 
moved _destSize() into "stable API" status
 2019-04-03 17:15:06 -07:00
Yann Collet
b5bedefabe fixed an old bug in LZ4F_flush() 
which remained undetected so far,
as it requires a fairly large number of conditions to be triggered,
starting with enabling Block checksum, which is disabled by default,
and which usage is known to be extremely rare.
