Tommy Murphy	0ee98c69c1	LibCompress: Brotli support metadata of skip_length=0 ... The relevant RFC section from https://www.rfc-editor.org/rfc/rfc7932#section-9.2 MSKIPBYTES * 8 bits: MSKIPLEN - 1, where MSKIPLEN is the number of metadata bytes; this field is only present if MSKIPBYTES is positive; otherwise, MSKIPLEN is 0 (if MSKIPBYTES is greater than 1, and the last byte is all zeros, then the stream should be rejected as invalid) So when skip_bytes is zero we need to break and re-align bytes. Added the relevant test case that demonstrates this from: https://github.com/google/brotli/blob/master/tests/testdata/x.compressed	2022-10-11 22:49:33 -06:00
Ben Wiederhake	8de7a91571	LibCompress+Tests: Demonstrate and fix faulty metadata length ... The test-case is heavily inspired by: https://github.com/google/brotli/blob/master/tests/testdata/x.compressed.01 Or in words: A metadata meta-block containing `Y` (which should be ignored), and then the actual data (a single `Z`). The bug used to skip one metadata byte too few, and thus read garbage.	2022-09-17 04:10:11 +00:00
Michiel Visser	d6a5b11f04	LibCompress: Implement Brotli decompressor ... This implements the BrotliDecompressionStream, which is a Core::Stream that can decompress another Core::Stream.	2022-05-21 22:41:40 +02:00
