[devpi-client] plugin for measuring replica latency
by Brack, Laurent P. May 23, 2018

Hello everyone, We have a devpi deployment with several replicas distributed around the world. Sometimes, a developer, say in Australia (with his index set to the local replica), triggers a build which is most likely to occur in North America. We have seen checksum error (due to our so so network infrastructure) when pulling things across the WAN. Most people use a homegrown bootstrap script, which among other things, measures the response time between the host and known replicas and lock on the fastest one. This has been working really well for us and has mitigated our network related issues. However, some people use the devpi client directly which uses whatever server it’s been configured with. So I was wondering if, perhaps through some client plugin hooks, we could integrate that feature, that is, perform latency measurements and switch to the best replica on the fly. I am not sure if we could make a generic plugin as it would need to be aware of the replicas available in your deployment, but if we can, then we would release it (if there is an interest of course). Anyhow, I am just fishing here, but any input/suggestions would be greatly appreciated. Thanks in advance. /Laurent

local private pip server with some public packages and their dependencies

Hi all we have some packages that are not public/open-source and we don't want them to be public. we want to create a private pip server repository with below specifications: - ability to push our own packages to it, and install them easily from pip(configured to use this local server) - ability to select some public packages and automatically fetch them and their dependencies, keep them update too(automatically obviously!) by public package and it's dependencies i mean we give it a file(some how give it! like reading a requirements.txt file), it reads the file, sees that i have a flask package in there, it downloads flask and provides it for me. it should look and get that flask itself needs some other packages such as jinja2, werkzwerg and click to work. so it should download them to. i think there is no pre-defined way to do it right? any solutions to do it?

Potential package index upload API specification
by Sumana Harihareswara May 8, 2018

I just posted to distutils-sig about the potential for a minimal specification for package index upload (I'm thinking of writing a PEP). Discussion should probably happen there: https://mail.python.org/mm3/archives/list/distutils-sig@python.org/thread/W… Thanks, -- Sumana Harihareswara Changeset Consulting https://changeset.nyc
