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*.

b2215f2a89 tried to clean another bunch of cppcheck warnings 
so "funny" thing with cppcheck
is that no 2 versions give the same list of warnings.

On Mac, I'm using v1.81, which had all warnings fixed.
On Travis CI, it's v1.61, and it complains about a dozen more/different things.
On Linux, it's v1.72, and it finds a completely different list of a half dozen warnings.

Some of these seems to be bugs/limitations in cppcheck itself.
The TravisCI version v1.61 seems unable to understand %zu correctly, and seems to assume it means %u.

86023f01f2 avoid final trailing comma for enum lists 
as detected in #485 by @JoachimSchneider.

Refactored the c_standards tests
so that these issues get automatically detected in CI tests.

b2e56d82bf Introduced constants LZ4F_INIT_* 
to simplify initialization of lz4frame.h structures.
Partially in response to #546.

98c0c7cf9d Fix bug in frame decompress example 
The decompression was failing as the srcEnd pointer in
decompress_file_internal was wrongly computed beyond
the end of the memory block.
We need to account for the fact that the header ("info")
was already read in the calling function ("alreadyConsumed").

550b40849f merge lz4opt.h into lz4hc.c 
Having a dedicated file for optimal parser
made sense during its creation,
it allowed Przemyslaw to work more freely on lz4opt, with less dependency on lz4hc,
moreover, the optimal parser was more complex, with its own search functions.

Since the optimal was rewritten last year, it's now a lot lighter.
It makes more sense now to integrate it directly inside lz4hc.c,
making it easier to edit (editors are a bit "lost" inside a `*.h` dependent on its #include position),
it also reduces the number of files in the project,
which fits pretty well with lz4 objectives.
(adding lz4hc requires "just" lz4hc.h and lz4hc.c).

b515ae9c99 refactored frameCompress.c example code

Also : nested structure ressources->computation
to make it easier to manage multiple exit points.

7f96babc4b Several changes to address a few concerns from Yann. See Google Group LZ4c topic 'Reusing compression/decompression resources' for details. 2015-10-29 21:47:13 -05:00

d1be164e49 Added a note about why char* is used. Also removed a binary that wasn't supposed to be in there. 2015-10-28 21:10:01 -05:00

0d25185671 Finished the two example files. Decided to avoid adding anything to lz4.c/h to expose LZ4_compress_generic(). 2015-10-28 20:54:51 -05:00
KyleJHarper
02be6631be Took out the basics and placed them into basics.c. Added decompression and a wrapper for the generic call. I will likely break this file up into 2 examples before submission. 2015-10-26 01:38:14 -05:00

67b3a24707 Final tests and reporting are done. As expected there isn't much to be gained by jumping the chain. In most of my tests I did see a moderate performance gain when invoking LZ4_compress_generic() directly with normal text. This could very easily be an edge case. Either way it's interesting and worth sharing. 2015-10-23 01:52:23 -05:00
