* unlzma: fix erroneous "while" instead of "if". Closes 4682Denys Vlasenko2017-01-091-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | These parts of the code essentially check whether stepping back by rep0 goes negative or not. LZMA SDK from lzma1604.7z has the following in the corresponding places: ... = dic[dicPos - rep0 + (dicPos < rep0 ? dicBufSize : 0)] Clearly, not loop here. Technically, "while" here works: if condition is false (because pos underflowed), it iterates once, adds header.dict_size (a.k.a. dicBufSize), this makes pos positive but smaller than header.dict_size, and loop exits. Now we'll just check for negative result of subtraction, which is less code: function old new delta unpack_lzma_stream 2659 2641 -18 (I hope 2 Gbyte+ dictionaries won't be in use soon).
