|
3 | _FP_gets still 70% of scan time. decode time: 24% _FP_gets, uulib_crc32 23%, UUValidData 11% |

|
|
5 | - include ecb.h to deal with compiler builtins and endianness. |
|
|
6 | - some further µ-optimisations in hot code, especially for yEnc. |
|
|
7 | - replace crc32 function by slice-by-16 version by Stephan Brumme, |
|
|
8 | which should speed up yEnc en-/decoding. |
|
|
9 | - yEnc: do not calculate two crcs per part, instead, combine |
|
|
10 | the part crcs together to form the file crc. |
|
|
11 | - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as |
|
|
12 | some draft mentions both and it is actually in active use. |
|
|
13 | - yEnc: ignore crc32= on multiparts, except on the last part. |
|
|
14 | - be more precise in documenting code licenses in COPYING. |

|
|
17 | - major performance improvement by simplifying code in _FP_gets |
|
|
18 | to not use fscanf. This might slow things down on platforms |
|
|
19 | with very slow fgetc. |

22 | - lint uulib: fix some format string type mismatches |

|
26 | - fix heap overflow (testcase by Noel Duffy, reported |
|
|
27 | by Robert Scheck). The defense-in-depth mechanism based |
|
|
28 | on mmap should make this unexploitable for other than denial |
|
|
29 | of service, on systems supporting mmap/mprotect. |
