fa7e6314cb remove possible mem leak in error cases by brotli compression too 2023-09-27 15:10:39 +02:00
sebres
396505c7d7 remove mem leak in error cases, for example on error by write or if it was cut or by partial extraction (no return without free, done list may contain not processed entries, so library leaks); 
+ small code deduplication

1eca571ea2 .zst, .br: avoid setting of size hint for unknown size by -si, since unpackSize will be supplied as -1 (UINT64_MAX) 2023-09-14 20:02:40 +02:00

eeae03eaa1 Add options to brotli and implement clean brotli .br support 
- allow to specify brotli window size
  - parameter -m0=brotli:long=n, BROTLI_MAX_WINDOW_BITS (24) used by default in brotli-mt, smaller == faster
  - note that :long can be set up to BROTLI_LARGE_MAX_WINDOW_BITS (30), whereas :wlog can be set up to BROTLI_MAX_WINDOW_BITS (24) only...
  - todo: check whether set of BROTLI_PARAM_LARGE_WINDOW to BROTLI_TRUE is needed if (lgwin > BROTLI_MAX_WINDOW_BITS)

- implementation of single-threaded brotli compression / decompression for .br data

b10fe5514f Modified lz4 code to create a fix for #73 
- by default, 7-Zip ZS creates lz4 streams with skippable frames, cause this
  makes parallel decompression possible
- but: sometimes this feature is not needed or wanted
- this patch will skip the writing of the additional frames for lz4, when
  compressing single threaded (-mmt=1)

68f3dcfeb9 Google has even more windowbits then BROTLI_MAX_WINDOW_BITS 
- it's the BROTLI_LARGE_MAX_WINDOW_BITS ;)
