These are now returning the correct canonical URL (thanks to a Cloudflare worker script), and letting search engines spider them again will hopefully boost visibility of that canonical URL.
Fixes #5983; possibly also has a bearing on #4306. A CSS rule dating from the original StreamField design was hiding the 'required' asterisk on fields within a required StreamField, presumably on the mistaken belief that they duplicate the information given by the top-level asterisk on the streamfield. (In #5983 this was reported as a regression in 2.7 when the react-streamfield CSS was introduced, so it's possible that the old design had something to mitigate this, e.g. an asterisk being inserted elsewhere.)
This fixes #6393 by modifying the constraint to use an IN condition
which supports both Postgres and SQL Server. Previously, the `|` (OR)
condition was only supported by Postgres because SQL Server only
supports AND conditions.
The implementation follows suggestions from @gasman in
https://github.com/wagtail/wagtail/issues/6393#issuecomment-732161057:
* Migration 0050 is modified to not break on SQL Server
* Added migration 0060 to add or replace the constraint
Additionally, this allows for and documents a `DATABASE_DRIVER` env
variable to be set for testing, to allow a different SQL Server driver
(e.g. FreeTDS on Mac/Linux); and adds the specific `host_is_server`
option for FreeTDS (won't affect SQL Server Native Client on CI).
Facebook and Instagram embeds configuration section should include the default finders for all other providers. It's unclear for someone who just wants to fix his facebook embeds
Same approach as 4023a90d6e for images - define an UploadedDocument model to hold the uploaded file up to the point where the required metadata has been supplied.
Boto3 has been around for a long time now. Adding a Boto-specific parameter in a tutorial is confusing (it was for me) as people are likely to install Boto3 directly and skip Boto. The `AWS_HEADERS` parameter was replaced by the `AWS_S3_OBJECT_PARAMETERS` parameter in Boto3 and the parameter that controls the access control list specifically is the `ACL`.
By the way, are the instructions on line 50 still relevant today?
Signal receivers must accept `**kwargs`, otherwise one runs into this:
```
File "/lib/python3.8/site-packages/django/dispatch/dispatcher.py", line 94, in connect
raise ValueError("Signal receivers must accept keyword arguments (**kwargs).")
ValueError: Signal receivers must accept keyword arguments (**kwargs).

This PR adds the 'choose' permission discussed in #4488. It limits Image and Document choosers to showing only those Collections (and their contents) for which the current user has the Choose permission.
It grants Choose permissions to the Root Collection to every existing Group that has the "Can access Wagtail admin" perm, via data migration. So there will be no change in behavior unless the user goes in and alters the Choose perms for their site's groups.
This PR has no effect on anything except choosers. The Image and Document index pages are still controlled solely by the 'add' and 'change' permissions, as those are only accessible by users who have those permissions in the first place. This means that it's now possible to configure a Group to allow its members to choose images from existing Collections when editing pages, *without* them being able to edit said images or add new ones.
It's a really small thing, but I honestly feel like Cynthia did most of the work of taking my workaround to production quality code and pushing it over the finish line. So she should be first here.
... when using the ``WAGTAILIMAGES_IMAGE_MODEL``/``WAGTAILDOCS_DOCUMENT_MODEL`` settings.
We can't really support this as we add new fields and methods to these base classes which all images/documents must support. If we did want to support swapping out the models entirely, every addition we make to the base models could be a breaking change.
