devpi-server: reliable private and caching server

Project description

devpi-server: server for private package indexes and PyPI caching

PyPI cache

You can point pip or easy_install to the root/pypi/+simple/ index, serving as a transparent cache for pypi-hosted packages.

User specific indexes

Each user (which can represent a person, project or team) can have multiple indexes and upload packages and docs via standard twine or invocations. Users and indexes can be manipulated through devpi-client and a RESTful HTTP API.

Index inheritance

Each index can be configured to merge in other indexes so that it serves both its uploads and all releases from other index(es). For example, an index using root/pypi as a parent is a good place to test out a release candidate before you push it to PyPI.

Good defaults and easy deployment

Get started easily and create a permanent devpi-server deployment including pre-configured templates for nginx and process managers.

Separate tool for Packaging/Testing activities

The complementary devpi-client tool helps to manage users, indexes, logins and typical upload and installation workflows.

6.10.0 (2023-12-19)


  • Use Authorization header instead of adding username/password to URL when fetching from mirror.

  • Fix #993: Use the pure Python httpx library instead of aiohttp to prevent delays in supporting newest Python releases.

Bug Fixes

  • Fix #996: support hashes other than sha256 in application/vnd.pypi.simple.v1+json responses.

  • Only compare hostname instead of full URL prefix when parsing mirror packages to fix mirrors with basic authentication and absolute URLs. See #1006

6.9.2 (2023-08-06)

Bug Fixes

  • Prevent duplicates when adding values to lists in index configuration with += operator.

6.9.1 (2023-07-02)

Bug Fixes

  • Fix #980: Remove long deprecated backward compatibility for old pluggy versions to fix error with pluggy 1.1.0.

6.9.0 (2023-05-23)


  • Support export directory layout for --replica-file-search-path option.

  • Fix #931: Add mirror_no_project_list setting for mirror indexes that have no full project list like google cloud artifacts or if you want to prevent downloading the full list for huge indexes like PyPI.

Bug Fixes

  • Keep a reference to async tasks to avoid their removal mid execution.

  • Support changed default of enforce_content_length in urllib3 >= 2.

  • Fix #934: Properly set PATH_INFO when outside URL is used with sub-path.

  • Fix #945: Adapt FatalError to be usable as an async HTTP response when updating a project on a mirror.

  • Fix #929: Cache normalized project names per transaction on mirror index instances.

Bug Fixes

  • Fix #914: add locking to list_projects_perstage of mirror indexes to prevent multiple slow concurrent updates of the full project name list.

  • Catch exceptions in async_httpget analog to httpget.

  • Add locking to mirror name cache to prevent race condition on updates.
