There's a closed pull request on the void-packages repository
python3-gmpy2: restore package
https://github.com/void-linux/void-packages/pull/33481
Description:
Upstream 2.1.0rc1 builds on python3.10.
This package is used by python3-mpmath for multiprecission arithmetic.
If not installed, mpmath defaults to python bigints which are very slow.
For example: compute 1M digits of pi using sympy:
$ isympy # without python3-gmpy2
In [1]: %time a=pi.n(1_000_000)
CPU times: user 49.4 s, sys: 2.96 ms, total: 49.4 s
Wall time: 49.4 s
vs.
$ isympy # with python3-gmpy2
In [1]: %time a=pi.n(1_000_000)
CPU times: user 632 ms, sys: 5.99 ms, total: 638 ms
Wall time: 639 ms
Note that just installing python3-gmpy2 brings this improvement.
Arguably python3-gmpy2 could be made a dependency of python3-mpmath.
This reverts commit f91cea99ddace872a5cdf0ae5d93fcc15b2f3191.
Also:
- fix hostmakedepends
- make tests work
- adopt
