Plone-app-blob

-------------------

- Use updated version of `createScales` as monkey-patched in
`plone.app.imaging`. Refs http://dev.plone.org/plone/ticket/10186
[witsch]

-------------------

- Change test setup to reuse the same directory when setting up blob
storages, thereby fixing some BBB test issues.
[witsch]

- Remove temporary monkey wrapper for `Blob.open` used to work around an
issue with `CMFEditions`. Refs http://dev.plone.org/plone/ticket/10200
[witsch]

- Use URL normalizer when generating content ids based on filename.
[terapyon, papago, witsch]

- Update view to analyse approximate content size grouped by type.
[witsch]

- Add `z3c.autoinclude` entry point for automatic ZCML loading in Plone 3.3+.
[witsch]

- Make sure image scales from old AT image fields are removed during
migration to blob fields, when using the BlobMigrator. This closes
http://dev.plone.org/plone/ticket/10160
[davisagli]

- Updated migration.pt to follow the recent markup conventions.

[spliter]

- Make it possible to delete image content.
[witsch]

-------------------

- Fix issues regarding migration from `OFS.File` and `OFS.Image` content.
[optilude, witsch]

- Revert changes to make things more robust in case of missing blob files.
This refs http://plone.org/products/plone.app.blob/issues/10
[witsch]

- Try to re-fetch blobs that have been removed from a client-side ZEO cache
before giving up and raising an error. This makes it possible to control
the client blob cache size via external processes (e.g. `cron`) even with
ZODB 3.8. See http://dev.plone.org/plone/changeset/32170/ for more info.
[svincic, witsch]

- Fix issue with incorrect values for "Type" catalog index after migration.
[yomatters, witsch]

-------------------

- Add support for accessing image scales via path expressions like
`here/image_thumb` for backward-compatibility.
[witsch]

------------------

- Unify the ATBlob factories (for CMF>=2.2 and CMF<2.2) while still
preventing events from being fired for the former.
[witsch]

- Fix range support for open ranges.
[j23d, witsch]

- Make the title field non-required for ATBlobs, since it will be
generated from the filename if necessary.
[davisagli]

- If a title was entered, use it instead of the filename to generate an
id for files (matching what was already done for images).
[davisagli]

- Update the CMF 2.2 version of the ATBlob factory to match a fix I made
in Archetypes 2.0a2.
[davisagli]

------------------

- Added a modified version of the customized ATBlob factory for use with
CMF 2.2.
[davisagli]

- Make sure that BlobWrappers for zero-length blobs still evaluate to
boolean True.
[davisagli]

- Implement range support for downloads. This fixes
http://plone.org/products/plone.app.blob/issues/11
[j23d, rossp, witsch]

- Fix image field validator to match that from `ATContentTypes`.
[rossp]

- With `ATContentTypes` >=2.0, check the `_should_set_id_to_filename`
method to determine if `ATBlob`'s `fixAutoId` method should set the
item id to the filename of the blob field. For images, don't set it
to the filename if a title was supplied.
[davisagli]

- Add blobbable adapters for Python file objects and OFS Pdata objects.
[davisagli]

- Add helper view to get a rough estimate of the total size of binary
content in a site.
