devpi-server: reliable private and pypi.org 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 setup.py 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 setup.py-based upload and installation workflows.
See https://doc.devpi.net on how to get started and further documentation.

Changelog
6.6.1 (2022-09-12)
Bug Fixes
Fix slowdown introduced in 6.6.0 when simple links for mirrors are requested more than once in the same thread.
Removed preservation of original server uuid during import. Imported state is different from the original server. Replicas could not detect the change and get into an inconsistent state.
Prevent cache trashing when updating simple links on mirrors for projects with huge number of releases.
Preserve toxresult filenames during import to keep them being accessible on the same URLs after the fix for #686 in 5.2.0.
6.6.0 (2022-08-16)
Features
Fix #592: return dict from list_projects_perstage of mirrors where the values contain the un-normalized project name. This allows support in devpi-web 4.1.0 to index them correctly.
Check name in project list instead of fetching project page for mirrors. This improves response times and avoids leaking typos of private package names upstream.
Use ETag header if provided by mirror to reduce bandwidth usage and latency.
Prevent concurrent updates of simple links on mirrors with a short lived lock.
Support PEP-691 conformant fetching for mirrors, and requests with JSON result for installers. Proxy servers should add compression support for the application/vnd.pypi.simple.v1+json content type (gzip_types for nginx).
Bug Fixes
Fix #743: support PEP427 escaped wheels with local version, where the + is replaced by _.
Fix #895: store and return content of data-yanked.
Fix #908: include basic auth from mirror_url when fetching packages.
Fix #914: switch to write transaction as late as possible when streaming a file from a mirror.
6.5.1 (2022-04-25)
Bug Fixes
Fix traceback when trying to delete already deleted release or toxresult.
Preserve index config settings of plugins during import instead of aborting, even if the plugin isn’t installed during import.
6.5.0 (2022-03-18)
Features
Added --no-checksum option to devpi-fsck to skip checksum validation and only check for file existence.
Split keyfs cache into a small changelog cache and a relpath cache, this lowers overall memory usage and prevents cache trashing.
Lower memory usage by avoiding to read release files into memory and instead use existing file objects.
Switch to platformdirs from appdirs.
Add streaming replica protocol, which is faster and uses less memory, especially when rebuilding a replica.
Better logging and handling if a thread unexpectedly dies.
Bug Fixes
Fix #871: authentication info in mirror_url wasn’t passed on to release links anymore.
Open database connection after file was downloaded during replication to avoid conflicts and locking.
Avoid hashing data twice when writing to storage.
Close HTTP responses and sessions when done to free resources as early as possible instead of waiting for garbage collection.
6.4.0 (2022-01-24)
Deprecations and Removals
As announced with 6.0.0, support for Python 3.6 has been dropped, because it has reached its end of life.
Features
When an installer user agent is detected the full list of projects is returned unsorted and with less info to improve performance and reduce memory usage.
Bug Fixes
Use __slots__ for some classes to reduce memory usage.
Fix exceptions related to logging for some edge cases.
