| * frame-api: add method to insert uncomressed dataAlexander Mohr2022-06-091-0/+23
| | | | | | | | | | | | | | | | new method `uncompressed_update` allows to insert blocks without compression into the lz4 stream. The usage is documented in the frameCompress example Signed-off-by: Alexander Mohr <alexander.m.mohr@mercedes-benz.com>

* fix UB of lz4frame:907Yann Collet2021-05-281-3/+3
| | | | | | now line 912 by ensuring pointer arithmetic is only performed if there is a reason for an internal buffer to be used.
* updated license & header datesYann Collet2020-11-251-1/+1
|
* minor refactor of lz4ioYann Collet2020-11-131-2/+3
| | | | | for readability. Mostly around --list capability
* LZ4F_decompress requires a valid dctx stateYann Collet2020-11-071-2/+4
| | | | | This is now explicitly documented and asserted. fix #927
* added target lz4-wlibYann Collet2020-08-111-3/+3
| | | | | | | | variant of lz4 linking to liblz4 dynamic library requires the dynamic library to expose static-only symbols (experimental API) Example for #888

| | | | fix #679, reported by @degski
* updated doc to underline difference between block and frameYann Collet2019-04-121-5/+8

* added a test for LZ4F_compressEnd()Yann Collet2018-10-091-0/+2
| | | | | | | | | | | | | | | which actively tries to make it write out of bound. For this scenario to be possible, it's necessary to set dstCapacity < LZ4F_compressBound() When a compression operation fails, the CCtx context is left in an undefined state, therefore compression cannot resume. As a consequence : - round trip tests must be aborted, since there is nothing valid to decompress - most users avoid this situation, by ensuring that dstCapacity >= LZ4F_compressBound() For these reasons, this use case was poorly tested up to now.
* avoid final trailing comma for enum listsYann Collet2018-09-131-10/+10
| | | | | | | as detected in #485 by @JoachimSchneider. Refactored the c_standards tests so that these issues get automatically detected in CI tests.
* added comments on version numbersYann Collet2018-09-061-5/+6
|
* Introduced constants LZ4F_INIT_*Yann Collet2018-09-051-9/+17
| | | | | to simplify initialization of lz4frame.h structures. Partially in response to #546.

* refactored frameCompress exampleYann Collet2018-01-311-4/+8
| | | | to better reflect LZ4F API usage.
* modified formulation for LZ4F_compressBound()Yann Collet2018-01-141-19/+19
| | | | | | previous version used an intentional overflow, which is defined since it uses unsigned type, but static analyzer complain about it.

* dictionary compression correctly uses compression levelYann Collet2017-08-101-1/+3
| | | | Not obvious : copying the state was copying cdict's compression level
* implemented dictionary compression in lz4frameYann Collet2017-08-091-19/+20
| | | | | note : only compression API is implemented and tested still to do : decompression API
* added dictID inside LZ4F_frameInfo_tYann Collet2017-08-091-2/+3
| | | | | Compressor can set dictID on LZ4F_compressBegin() Decompressor can retrieve it using LZ4F_getFrameInfo()
