devpi-1.1: improved pypi cache, data migration, wheels, ...

Show key headers only | View raw

The devpi-{server,client}-1.1 releases bring a lot of refinements
and improvements for serving standalone pypi mirrors or company/private
indexes which seemlessly merge in PyPI releases, mainly:

- improved speed and semantics of pypi cache.  devpi-server
  has been tested to correctly mirror all ~34000 projects
  on pypi.python.org now, and minimizes upstream interactions
  by fully exploiting the existing mirroring protocols.

- data migration: new --upgrade/import/export options.
  versioning of serverstate and API calls so that future
  changes can be detected by clients.

- better support for ".whl" files and many other little 
  improvements and bug fixes, see the changelog
  below for more info.

Note that devpi-1.1 will require to ``--upgrade`` your 1.0 
server state before you can serve with devpi-server-1.1 release.

Docs also were updated.  Here is a Quickstart tutorial 
for efficient pypi-mirroring on your laptop:: 
                                                                                
    http://doc.devpi.net/1.1/quickstart-pypimirror.html
                                                                                
And if you want to manage your releases or implement staging
as an individual or within an organisation::
                                                                                
    http://doc.devpi.net/1.1/quickstart-releaseprocess.html
                                                                                
If you want to permanently install devpi-server and potentially
access it from many clients::
                                                                                
    http://doc.devpi.net/1.1/quickstart-server.html
                                                                                
More documentation and the beginning of an exhaustive user manual::

CHANGELOG 1.1
----------------------------

devpi-server:

- systematically test pypi/mirror code against all 34K pypi projects
  so that we know that all http/https installable archive links that pypi offers 
  are correctly recognized by devpi-server's root/pypi index.

- if no pypi mirror state is known, devpi-server now calls
  pypi to obtain names/serials.  It will fail to start
  if no such initial connection is possible.  Once a first mirror
  state is known, subsequent devpi-server starts will
  not perform this initial query.

- speed up and make more reliable all operations on private packages which
  have no pypi.python.org release: we can now determine if a project
  exists on pypi and under which name exactly without
  remote queries or redirects to pypi.python.org.

- fix issue45: register/upload package names are now properly 
  validated and redirects take place if e.g. a project was
  registered as "name-sub" and "+simple/name_sub" is queried.

- new --upgrade-state command to allow for easy and safe
  in-place upgrading of server state.  This is not guranteed
  to be possible for all future releases which might require
  using --export with an older version and --import with a newer
  version.

- new --export/--import options to dump and import server contents:
  users, indexes, docs, release files and (test) attachments.
  Note that root/pypi (PyPI-caching information) will not be exported/imported.
  (maybe in the future if there is demand). 

- fix issue49: both push and import/export now support docfiles.  Note,
  however, that docfiles relate to a project as a whole and are not tied
  to a particular version.  This property is inherited from the PyPI
  standard upload_docs action and cannot be changed without interfering
  or replacing the upload_docs protocol of setuptools/sphinx.

- fix issue51: return 200 code if release file is successfully uploaded 
  but jenkins could not be triggered (previously returned 500)

- reject simple/NAME if NAME contains non-ascii characters
  (PEP426 naming rules)

- devpi-server now returns a X-DEVPI-API-VERSION and
  X-DEVPI-SERVER-VERSION header.  For future incompatible changes 
  these versions allow clients to reject interactions.

- also add ".serverversion" file and write it if it does not
  exist, and make devpi-server use it to verify if
  operating on a compatible server data layout, otherwise bail out.

- address issue43: --gendeploy now uses pip without --pre and
  explicitely instructs pip to install the exact same version 
  of devpi-server with which --gendeploy is issued.

- fix issue46 -- for GET /root/pypi/ only show a link to the
  simple page instead of computing "latest in-stage packages"
  which is only useful for devpi's user indices.

- fix issue37: upload with expired login causes proper 401


devpi-client:

- detect "X-DEVPI-API-VERSION" header and check for compatibility.
  devpi-client currently supports version "1" and warns if
  no version is known (defaulting to "1").

- getjson now prints http reply headers if "-v|--verbose" was supplied.

- fix issue52: add "--no-vcs" option to force "devpi upload" to not
  vcs-export files before executing build/upload

- fix issue50: introduce "--toxargs" to "devpi test" invocations in
  order to add arbitrary arguments to tox.

- fix issue43: set PIP_PRE environment variable when executing
  "devpi install ..." so that the behaviour between 
  pip < 1.4 and >= 1.4 is normalized to always install 
  development versions.

- fix issue47: set PIP_USE_WHEEL with "devpi install ..." so that
  it will automatically pick up wheel files if pip>1.4 is used.

- fix issue42: allow to set empty bases for an index, so that it doesn't
  inherit anything.

- fix issue44: "use -l" doesn't break when a user has no index

- devpi test now invokes tox in-process (by importing tox) rather than
  a subprocess.
