devpi-server 4.2.1

devpi-server: reliable private and caching server

devpi-server: pypi server for caching and private indexes

consistent robust pypi-cache

You can point pip or easy_install to the root/pypi/+simple/ index, serving as a self-updating transparent cache for pypi-hosted and external packages. Cache-invalidation uses the latest and greatest PyPI protocols. The cache index continues to serve when offline and will resume cache-updates once network is available.

user specific indexes

Each user (which can represent a person or a project, team) can have multiple indexes and upload packages and docs via standard invocations command. Users and indexes can be manipulated through 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 cron.

separate tool for Packaging/Testing activities

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

See for getting started and documentation.


4.2.1 (2016-12-22)

  • the new --init option now exits after done, so it can be used in automation scripts. When using with --start it still starts the background server immediately.

4.2.0 (2016-12-14)


Before devpi-server 4.2.0 passwords were hashed with a very weak algorithm. It’s strongly recommended to change any passwords created before 4.2.0 after upgrading! The password salt and hashes are exposed via the /+changelog URL used for replication. If you use replication you should use client side certificates or https with basic authentication to secure /+changelog.


Starting with devpi-server 4.2.0 the replication protocol is disabled by default to prevent accidental information leaks, like password hashes. To enable the replication protocol, you have to use --role master when starting the master devpi-server instance.

  • fix issue378: the replication protocol is now disabled by default.
  • fix push to PyPI by skipping failing “register” step and adding additional fields in POST data on “file_upload”.
  • fix issue372: correctly set isolation_level for sqlite3 connections. This also fixes Python 3.6 compatibility.
  • fix issue334: The event handler for the simple page cache failed when an index was deleted and a new replica tried to run the event hooks.
  • fix issue314: Fetch external file on replica from original source if master is down.
  • fix issue363: Replace weak password hashing with argon2 using passlib. Existing logins will be migrated on login.
  • fix issue377: Add new --init option required to initialize a server directory. This prevents accidental use of wrong or empty --serverdir.
  • fix issue285: require waitress >= 1.0.1 to enable IPv6 support.

4.1.1 (2016-10-14)

  • when a project has no releases (only register ran) and it isn’t whitelisted, then upstream releases will now be blocked as expected.
  • Adjust event processing status messages and the times when they are shown: After 5 minutes of no event processing there will be a warning. After 30 minutes this will turn into a fatal status. After 1 hour of not being in sync there will be a warning. After 6 hours of desync the status turns fatal.
  • handle sqlite3.NotSupportedError when the installed sqlite doesn’t support URI filenames at all.

4.1.0 (2016-07-15)

  • Try opening read only transactions in SQLite read only mode for better concurrency/locking behaviour. This is officially supported with Python 3.4, but many systems allow it implicitly in older Python versions.
  • fix issue353: If an index inherits from a mirror with an empty cache and the mirror is returning errors, there would be an error returned by devpi. Now this situation is treated like the mirror has no releases and just the releases from the index are returned.
  • fix issue352: When there was an issue during commit or rollback, the thread local info got into an inconsistent state. This caused an AttributeError whenever that thread was used. Eventually this could exhaust all worker threads and make devpi unresponsive.
  • fix issue354: allow more general agent versions, such as ‘Python-urllib/3.5’ to appear before the installer user agent string so redirects for setuptools versions which had that work.
  • fix issue214: change the order in which indices are searched to fix the mirror whitelisting and also make sure that packages, if available, are always installed from internal indices instead of root/pypi.

4.0.0 (2016-05-12)


Please note that devpi-server 4.0.0 is a bug fix/compatibility release as it only changes project name normalization compared to 3.1.x. The internal use of the normalization requires an export/import cycle, which is the reason for the major version increase. There are no other big changes and so everyone who used devpi-server 3.x.y should be fine just using 4.0.0. It’s also fine to export from 2.6.x and import with 4.0.0.

  • require devpi-common 3.0.0 which changes the normalization of project names.
  • allow import of exported data from devpi-server 3.1.2 with inconsistently normalized project names.
