[gentoo-portage-dev] [PATCH 10/14] portage.checksum: Reorder to avoid loading redundant impls

Reorder the checksum implementations to start with the most preferred implementation, and try fallbacks only if the most preferred implementation is not available. Most importantly, this means that Portage will no longer attempt to load all hash libraries in the system, especially when it can

[gentoo-portage-dev] [PATCH 11/14] portage.checksum: Support pygcrypt as optimized fallback

[gentoo-portage-dev] [PATCH 13/14] portage.checksum: Support pygost as fallback Streebog provider

Support the pure Python implementation of Streebog in pygost as a fallback algorithm. The code is horrible (it stores all the data in memory before hashing), so it is really intended as last fallback. --- pym/portage/checksum.py | 15 +++ 1 file changed, 15 insertions(+) diff --git

Hi, Here's a huge batch of patches for portage.checksum and relevant stuff. It's not a complete rewrite as I have originally planned, and it's still not the code I'd like to see but functionally it has been improved a lot. Notable changes: 1. Other modules no longer use hashfunc_map, now they
