* HttpStream must be read prior to knowing it length
We also need to create the send prior to saving the stream so we
have well defined save location. Solve chicken-and-egg problem by saving
the Send twice. This also allows for validation that the stream received
is the same length as that promissed by the content-length header
* Get encrypted file length from request
* Add sendId to path
Event Grid returns the blob path, which will be used to grab a Send and verify file size
* Re-validate access upon file download
Increment access count only when file is downloaded. File
name and size are leaked, but this is a good first step toward
solving the access-download race
* Get limited life attachment download URL
This change limits url download to a 1min lifetime.
This requires moving to a new container to allow for non-public blob
access.
Clients will have to call GetAttachmentData api function to receive the download
URL. For backwards compatibility, attachment URLs are still present, but will not
work for attachments stored in non-public access blobs.
* Make GlobalSettings interface for testing
* Test LocalAttachmentStorageService equivalence
* Remove comment
* Add missing globalSettings using
* Simplify default attachment container
* Default to attachments containe for existing methods
A new upload method will be made for uploading to attachments-v2.
For compatibility for clients which don't use these new methods, we need
to still use the old container. The new container will be used only for
new uploads
* Remove Default MetaData fixture.
* Keep attachments container blob-level security for all instances
* Close unclosed FileStream
* Favor default value for noop services
* Add Disable Send policy
* Test DisableSend policy
* PR Review
* Update tests for using CurrentContext
This required making an interface for CurrentContext and mocking out
the members used. The interface can be expanded as needed for tests.
I moved CurrentContext to a folder, which changes the namespace
and causes a lot of file touches, but most are just adding a reference
* Fix failing test
* Update exemption to include all exempt users
* Move all CurrentContext usages to ICurrentContext
* PR review. Match messaging with Web
