paraslash/fec.c, branch masterparaslash - network audio streaming toolshttps://git.tue.mpg.de/cgit/paraslash/atom?h=master2026-03-22T18:32:14Zfec: Remove modnn().2026-03-22T18:32:14ZAndre Nollmaan@tuebingen.mpg.de2026-03-11T23:38:46Zurn:sha1:e4a6c8795b19df0ad41f675a9a711b3a76163032
The compiler should be smart enough to optimize the modulo operation. Besides,
this code is only executed via fec_new(), which is not performance critical.
fec: Avoid explicit zeroing.2026-03-22T18:31:07ZAndre Nollmaan@tuebingen.mpg.de2026-03-11T23:27:13Zurn:sha1:0a4f081194281ab2a8ddcd1dc64a8e0ee08b3be7
We have helpers for that.
fec: Replace arr_alloc(1, k) by alloc(k).2026-03-22T18:31:03ZAndre Nollmaan@tuebingen.mpg.de2026-03-11T23:24:22Zurn:sha1:08a455c9edb7475d22b595eca48d5250002f3e18
Both are equivalent, but the latter is shorter and more performant because
it avoids a multiplication and a check for overflow.
fec: Remove pointless alloc_matrix().2026-03-22T18:30:59ZAndre Nollmaan@tuebingen.mpg.de2026-03-11T23:14:03Zurn:sha1:0e0d09198fcfe18ae9dd9da8edcc92514f37ceb0
We may as well call arr_alloc() directly.
Improve FEC documentation.2025-10-08T18:58:23ZAndre Nollmaan@tuebingen.mpg.de2025-06-16T18:04:05Zurn:sha1:54dc6d5d184d8b3d0540f527363c54f6619689cf
A cup of dedox for fec.c and the new two-paragraph overview of the fec API.
fec: Don't oversize gf_exp[].2025-08-02T23:06:42ZAndre Nollmaan@tuebingen.mpg.de2025-07-08T19:00:32Zurn:sha1:80e0ab1b2cdc040820eb11c496da93cbea4b16a8
Apart from the initialization code, there is only one user of the Galois
field exponential table. This user passes a value modulo GF_SIZE, so we
never access the second half of the array.
fec.c: Remove an unused #include.2025-05-26T15:45:53ZAndre Nollmaan@tuebingen.mpg.de2025-05-25T17:45:58Zurn:sha1:eabd7686ad43af9eba676983642fc5a4ed464a70
The fec code does not need the helpers from portable_io.h.
Include regex.h from para.h.2025-05-19T17:35:58ZAndre Nollmaan@tuebingen.mpg.de2025-05-18T20:05:45Zurn:sha1:67388cd4fae0cfd1674aada937f4f4d2faeeee1f
Every .c file includes it anyway.
string: Introduce arr_alloc().2022-07-29T17:22:09ZAndre Nollmaan@tuebingen.mpg.de2021-10-27T18:40:04Zurn:sha1:27c08870ba172782f6406045007b6ff32a4f7329
Change all callers of alloc() which pass a product of two integers as
the allocation size to call the new function instead. This function
aborts if the multiplication overflows. With arr_alloc() in place,
alloc() reduces to a trivial wrapper which calls new arr_alloc()
with the first argument equal to one.
string: Rename para_calloc() -> zalloc().2022-07-29T17:22:09ZAndre Nollmaan@tuebingen.mpg.de2021-11-09T17:41:17Zurn:sha1:26a032fffa6c6e6f092ed3d14c2b5f08e5c736d6
Reword the documentation a bit since the function has never been a
wrapper for calloc(3). No code changes.
