Subject: [PATCH 001/103] Completely remove the revision controller.

Remove the legacy revision controller 'tests'

Activities are now just templates. Removes all _html 'helpers'.

Remove leftover mentions of activity_streams.py and missed _html helpers from actions.

Switch activity action based on group type.

Fix 'View this version' links.

Redirect legacy history page to activity feed (this page is not referenced by anything in core ckan)

Revert a small change that breaks old fanstatic-based CKAN.

Remove mentions to user_activity_list_html and _html test checks.

Store complete package dict in activity. Store user name at time of change. Show historic package versions.

Legacy tests do not include valid users when creating test packages.

Ignore authentication when creating the package dict for the activity record.

Subject: [PATCH 004/103] Update less version, to avoid merge main.css
 conflicts in future. Clearly the last person to use less used a more recent
 version (than 2.5.2) because the color values in main.css are no longer
 long-hand (e.g. main.css has #ffffff rather than the #fff short-hand found in
 the .less file)

Subject: [PATCH 040/103] Do not save c.package_activity_stream to c any more
 because it is better practice to pass it in to the template in extra_vars. We
 are backward incompatible already - the value is changing from a lump of HTML
 to an object - so if anyone has customized the template they need to fix it
 anyway.

Subject: [PATCH 042/103] Simplify the activity model queries again, to not
 risk them taking too long. Keep the titles in the
 activity[data][package/group/organization] even if the rest of the data is
 not provided (eg not logged in), so that the titles can always be displayed.
 We dont have the package/group/organization names, but that can be sorted
 using redirects in a following commit.

 Changelog
 ---------
 
+v2.9.0 TBC
+==========
+
+ * This version requires script 'migrate-revisions.py' to be run after CKAN is
+   upgraded and operating again. This is because this script takes a while to
+   run, adding in the Activity Stream detail, visible only to admins by default.
+   This is a separate step to the database upgrade.
+   Run migrate_revisions.py like this:
+    python ckan/migration/migrate_revisions.py -c /etc/ckan/production.ini
+

Subject: [PATCH 066/103] Fixes for templates when viewing old datasets

* Remove c.revision_date and c.revision_id stuff from templates - that was how old datasets were shown before this PR.
* Change links from pkg.name to pkg.id when viewing an old dataset version (i.e. when is_activity_archive=True) because package.name may not be current. Instead we create the link with package.id and let CKAN redirect the user. Because of this we need to pass is_activity_archive to both package/snippets/resource_item.html and package/snippets/resources.html which have links.
* Hide 'download_resource_button' when viewing an old dataset version (i.e. when is_activity_archive=True) because the datastore will be the latest version of the data, not the old version that matches the metadata.

Subject: [PATCH 067/103] Fix comma missing in resource_read.html and template
 docs

* Don't display resource preview when viewing an old dataset version (i.e. when is_activity_archive=True) because the datastore will be the latest version of the data, not the old version that matches the metadata.
* Fix comma missing in ckan/templates/package/resource_read.html
* Improve docs of the package html

Subject: [PATCH 079/103] Migration errors stores just title, instead of
 incorrectly storing the previous dataset. If you View it, it now 404s. Allow
 command-line option to answer the wipe_activity_detail quesion, for
 automation purposes.

Subject: [PATCH 092/103] Fix package_show of old revision

Fix in package_dictize_with_revisions of 'metadata_modified' and 'organization' -
it was showing the current package's version, not the older revision.

Test fix - del activity.data['package'] was unreliably committed.

 verions of CKAN where the revision stuff is split off into a separate model

 v.2.9.0 TBA
 ==================
 
- * This version requires script 'migrate_package_activity.py' to be run
-   *before* CKAN is upgraded to this version (or higher). The idea is you do
-   this special migration while CKAN is running, because the script takes a
-   while to run. It adds in the Activity Stream detail, visible only to admins
-   by default. You will not be able to run ``paster db upgrade`` until
-   'migrate_package_activity.py' is done.
-   Download and run migrate_package_activity.py like this:
+ * When upgrading from previous CKAN versions, the Activity Stream needs a
+   migrate_package_activity.py running for displaying the history of dataset
+   changes. This can be performed while CKAN is running or stopped (whereas the
+   standard `paster db upgrade` migrations need CKAN to be stopped). Ideally it
+   is run before CKAN is upgraded, but it can be run afterwards. If running
+   previous versions or this version of CKAN, download and run
+   migrate_package_activity.py like this:
 
      cd /usr/lib/ckan/default/src/ckan/
      wget https://raw.githubusercontent.com/ckan/ckan/3484_revision_ui_removal2/ckan/migration/migrate_package_activity.py
      wget https://raw.githubusercontent.com/ckan/ckan/3484_revision_ui_removal2/ckan/migration/revision_legacy_code.py
      python migrate_package_activity.py -c /etc/ckan/production.ini
 
-   More info: https://github.com/ckan/ckan/wiki/Migrate-package-activity
+   Future versions of CKAN are likely to need a slightly different procedure.
+   Full info about this migration is found here:
+   https://github.com/ckan/ckan/wiki/Migrate-package-activity
 
  * A full history of dataset changes is now displayed in the Activity Stream to
-   admins, and optionally to the public. Open data CKANs upgrading are
-   encouraged to make this history open to the public, by setting this to
-   production.ini: ``ckan.auth.public_activity_stream_detail = true``
-   (#3972)
+   admins, and optionally to the public. By default this is enabled for new
+   installs, but disabled for sites which upgrade (just in case the history is
+   sensitive). When upgrading, open data CKANs are encouraged to make this
+   history open to the public, by setting this in production.ini:
+   ``ckan.auth.public_activity_stream_detail = true`` (#3972)

Subject: [PATCH 102/103] Improve tests

* Use PackageDictizeMonkeyPatch to patch package_dictize, because a context manager like this cleans up after itself effectively, so any tests that run after test_migrate_package_activity.py and test_revision_legacy_code.py will use the standard package_show now.
* Fix test_revision_legacy_code.py now package_extra_revision table is not being populated at the moment.
* Copied in create_object_version() from vdm, so we can use PackageExtraRevision without its .continuity being mapped to the PackageExtra.
