[Distutils] devpi-{server,web}-2.5.0 perf/bug fix releases

[holger krekel]

We just released devpi-{server,web}-2.5.0 to pypi, see changelogs below
for more details.  While it's not required to do an export/import cycle
for this release it's recommended especially if you are running with replicas.

Docs for the private pypi packaging server at: http://doc.devpi.net

Thanks to Florian Schulze, Jason R. Coombs and all issue reporters.

For your information, we are now starting work for devpi-server-3.0 
which will introduce further speedups, internal code simplifications
and new features (like mirroring from arbitrary pypi-servers).

cheers,
holger krekel



server-2.5.0 (2015-11-19)
-------------------------

- fix a regression of 2.3.0 which would cause many write-transactions
  for mirrored simple-page entries that didn't change.  Previous to the fix,
  accesses to mirrored simple pages will result in a new
  write-transaction every 30 minutes if the page is accessed which
  is likely on a somewhat busy site.  If you running with replicas
  it is recommended to do an an export/import cycle to remove all 
  the unneccessary writes that were produced since devpi-server-2.3.0.
  They delay the setup of new replicas considerably.

- add info about pypi_whitelist on simple page when root/pypi is blocked for
  a project.

- replica simple-page serving will not unneccessarily wait for new 
  simple-page entries to arrive at the replication side if the master 
  does not return any changes in the initial simple-page request.
  Previously a replica would wait for the replication-thread to catch
  up even if no links changed.

- fix setup.py to work on py34 and with LANG="C" environments.
  Thanks Jason R. Coombs.

- fix issue284: allow users who are listed in acl_upload to delete packages


web-2.5.0 (2015-11-19)
----------------------

- fix issue288: classifiers rendering wrong with read only data views

- index.pt, project.pt, version.pt: added info about pypi_whitelist. This
  requires devpi-server > 2.4.0 to work.

- fix issue286: indexing of most data failed due to new read only views
