| 3 | _FP_gets still 70% of scan time. decode time: 24% _FP_gets, uulib_crc32 23%, UUValidData 11% |
3 | 04:59:03 <kentnl> schmorp: you may want to change the description on Convert-UUlib, because your bundled copy |
|
|
4 | is now better maintained and has fewer security risks than upstreams :p |
|
|
5 | 04:59:49 <kentnl> to the point I've been humoring the idea of cribbing its code and shipping it as a |
|
|
6 | replacement for other things currently using the original uulib |

7 | 06:51:00 <schmorp> kentnl: well, hmm, but change it to what, it still is an interface to "a" uulib library at |

|
|
12 | - very minor code improvements. |
|
|
13 | - use getc instead of fgetc. |
|
|
14 | - clean up FP _symbol names. |
|
|
15 | - use feof_unlocked and ferror_unlocked. |

|
|
21 | - new function: GetFileList. |
|
|
22 | - experimental perlmulticore support (see manpage). |
|
|
23 | - Initialize is now a NOP and CleanUp automatically initializes again. |
|
|
24 | - updated example decoder and documentation a bit. |
|
|
25 | - include ecb.h to deal with compiler builtins and endianness. |
| 5 | - some further µ-optimisations in hot code. |
26 | - some further µ-optimisations in hot code, especially for yEnc. |
|
|
27 | - replace crc32 function by slice-by-16 version by Stephan Brumme, |
|
|
28 | which should speed up yEnc en-/decoding. |
|
|
29 | - yEnc: do not calculate two crcs per part, instead, combine |
|
|
30 | the part crcs together to form the file crc. |
| 6 | - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as |

33 | - yEnc: ignore crc32= on multiparts, except on the last part, |
|
|
34 | which avoids spurious corruption warnings. |
|
|
35 | - be more precise in documenting code licenses in COPYING. |
|
|
36 | - convert constant creation to the method I normally use. |
|
|
37 | - use common::sense. |
