The commit 20b2a42f49 broke
upload handlers, because previously we passed through the
native File object to the handler, not the uppy-wrapped
File object.
We want to be able to skip plugins from doing any work under
certain conditions, and to be able raise their own errors if
a file being uploaded is completely incompatible with the concept
of the plugin if it is enabled. For example, the UppyChecksum plugin
is happy to skip hashing large files, but the UppyUploadEncrypt
plugin from discourse-encrypt relies on the file being encrypted
to do anything with the upload, so it is considered a blocking
error if the user uploads a file that is too large.
This improves the base functions available in uppy-plugin-base and
extendable-uploader to handle this, as well as introducing a
HUGE_FILE_THRESHOLD_BYTES variable which represents 100MB in bytes,
matching the ExternalUploadManager::DOWNLOAD_LIMIT on the
server side.
discourse-encrypt to take advantage of this new functionality will
follow in discourse/discourse-encrypt#141

This abstracts interaction with uppy for uppy plugin classes
into base classes for Preprocessor plugins, so anyone
making these uppy plugins doesn't have to think as much about uppy
underneath the hood. This also makes the logging and validation
nicer, and provides a more consistent way to emit progress and
completion events.
In a future commit, we will introduce another base class for
`UploadUploaderPlugin` which will be used to be able to hijack
the upload process to go to a different provider (e.g. for discourse-video)
Adds uppy upload functionality behind a
enable_experimental_composer_uploader site setting (default false,
and hidden).
When enabled this site setting will make the composer-editor-uppy
component be used within composer.hbs, which in turn points to
a ComposerUploadUppy mixin which overrides the relevant
functions from ComposerUpload. This uppy uploader has parity
with all the features of jQuery file uploader in the original
composer-editor, including:
progress tracking
error handling
number of files validation
pasting files
dragging and dropping files
updating upload placeholders
upload markdown resolvers
processing actions (the only one we have so far is the media optimization
worker by falco, this works)
cancelling uploads
For now all uploads still go via the /uploads.json endpoint, direct
S3 support will be added later.
Also included in this PR are some changes to the media optimization
service, to support uppy's different file data structures, and also
to make the promise tracking and resolving more robust. Currently
it uses the file name to track promises, we can switch to something
more unique later if needed.
Does not include custom upload handlers, that will come
in a later PR, it is a tricky problem to handle.
Also, this new functionality will not be used in encrypted PMs because
encrypted PM uploads rely on custom upload handlers.
