Previously, if an admin user tried to add/remove
users to another user's ignored list, it would
be added to their own ignore list because the
controller used current_user. Now for admins only
a source_user_id parameter can be passed through,
which will be used to ignore the target user for
that source user.
The user can select what happens with a bookamrk after it expires. New
option allow bookmark's reminder to be kept even after it has expired.
After a bookmark's reminder notification is created, the reminder date
will be highlighted in red until the user resets the reminder date.
User can do that using the new Clear Reminder button from the dropdown.
When creating files with create-multipart, if the file
size was somehow zero we were showing a very unhelpful
error message to the user. Now we show a nicer message,
and proactively don't call the API if we know the file
size is 0 bytes in JS, along with extra console logging
to help with debugging.
This change adds support for the categories endpoint to have an api
scope. Only adds GET scope for listing categories and for fetching a
single category.
See: https://meta.discourse.org/t/218080/4
This PR adds an extra description to the 2FA page when granting a user admin access. It also introduces a general system for adding customized descriptions that can be used by future actions.
(Follow-up to dd6ec65061)
This feature was rarely used, could be used for spamming users and was
impossible to add a context to why the user was notified of a topic. A
simple private messages that includes the link and personalized message
can be used instead.
This commit extends the original copy-codeblocks initializer,
renaming it to codeblock-buttons, and adding another button
to make the code block fullscreen in a modal window. The fullscreen
code is then run through highlight.js.
This commit also moves much of the code out of the initializer
and into a reusable CodeblockButtons class, so it can also be used
in the fullscreen code modal for the copy + paste button.
The fullscreen button will not be shown if there is no scroll overflow
in the code block, nor will it be shown on mobile. This commit also
changes the fullscreen table button to not show on mobile.
This will make long lines of code much easier to read and interact
with. This is gated behind the same `show_copy_button_on_codeblocks`
site setting.
* FEATURE: upload an avatar option for uploading avatars with selectable avatars
Allow staff or users at or above a trust level to upload avatars even when the site
has selectable avatars enabled.
Everyone can still pick from the list of avatars. The option to upload is shown
below the selectable avatar list.
refactored boolean site setting into an enum with the following values:
disabled: No selectable avatars enabled (default)
everyone: Show selectable avatars, and allow everyone to upload custom avatars
tl1: Show selectable avatars, but require tl1+ and staff to upload custom avatars
tl2: Show selectable avatars, but require tl2+ and staff to upload custom avatars
tl3: Show selectable avatars, but require tl3+ and staff to upload custom avatars
tl4: Show selectable avatars, but require tl4 and staff to upload custom avatars
staff: Show selectable avatars, but only allow staff to upload custom avatars
no_one: Show selectable avatars. No users can upload custom avatars
Co-authored-by: Régis Hanol <regis@hanol.fr>
Similar site settings exist for likes and edits and the new ones work
in a similar way.
By default, users below TL2 have a limit of 20, the limit is increased
by 1.5 for TL2 users up to 30, by 2 for TL3 users up to 40 and by 3 for
TL4 users up to 60.
2FA support in Discourse was added and grown gradually over the years: we first
added support for TOTP for logins, then we implemented backup codes, and last
but not least, security keys. 2FA usage was initially limited to logging in,
but it has been expanded and we now require 2FA for risky actions such as
adding a new admin to the site.
As a result of this gradual growth of the 2FA system, technical debt has
accumulated to the point where it has become difficult to require 2FA for more
actions. We now have 5 different 2FA UI implementations and each one has to
support all 3 2FA methods (TOTP, backup codes, and security keys) which makes
it difficult to maintain a consistent UX for these different implementations.
Moreover, there is a lot of repeated logic in the server-side code behind these
5 UI implementations which hinders maintainability even more.
This commit is the first step towards repaying the technical debt: it builds a
system that centralizes as much as possible of the 2FA server-side logic and
UI. The 2 main components of this system are:
1. A dedicated page for 2FA with support for all 3 methods.
2. A reusable server-side class that centralizes the 2FA logic (the
`SecondFactor::AuthManager` class).
From a top-level view, the 2FA flow in this new system looks like this:
1. User initiates an action that requires 2FA;
2. Server is aware that 2FA is required for this action, so it redirects the
user to the 2FA page if the user has a 2FA method, otherwise the action is
performed.
3. User submits the 2FA form on the page;
4. Server validates the 2FA and if it's successful, the action is performed and
the user is redirected to the previous page.
A more technically-detailed explanation/documentation of the new system is
available as a comment at the top of the `lib/second_factor/auth_manager.rb`
file. Please note that the details are not set in stone and will likely change
in the future, so please don't use the system in your plugins yet.
Since this is a new system that needs to be tested, we've decided to migrate
only the 2FA for adding a new admin to the new system at this time (in this
commit). Our plan is to gradually migrate the remaining 2FA implementations to
the new system.
For screenshots of the 2FA page, see PR #15377 on GitHub.
* FIX: Don't accept accents in slug if generation_method == 'ascii'
Fixes bug reported in:
- https://meta.discourse.org/t/404-when-trying-to-edit-category-with-accent-in-slug/214762
- https://meta.discourse.org/t/formatting-and-accents-in-urls/215734/5
Assuming `SiteSetting.slug_generation_method == 'ascii'.
If the user provides a slug containing non-ascii characters while
creating the category, the user will receive a 404 error just
after saving the category since the slug will be escaped anyway but
Category.find_by_slug_path won't escape the category slug
causing the Edit Page of the category to be inaccessible.
This commit checks the provided slug and raises an error if the
provided slugcontains non-ascii characters ensuring that the
provided value is consistent with the site settings.
It also changes Category.find_by_slug_path to always escape the slug,
since if present, it is escaped anyway in Category.ensure_slug to
prevent the 404 in the Edit Category Page in case the user already
have some category with a non-ascii slug.
* Removed trailing whitespace
This can happen if the topic to which a user is invited is in a private
category and the user was not invited to one of the groups that can see
that specific category.
This used to be a warning and this commit makes it an error.

## Updates to rate_limiter
When limiting reinvites I found that **staff** are never limited in any way. So I updated the **rate_limiter** model to allow for a few things:
- add an optional param of `staff_limit`, which (when included and passed values, and the user passes `.staff?`) will override the default `max` & `secs` values and apply them to the user.
- in the case you **do** pass values to `staff_limit` but the user **does not** pass `staff?` the standard `max` & `secs` values will be applied to the user.
This should give us enough flexibility to
1. continue to apply a strict rate limit to a standard user
2. but also apply a secondary (less strict) limit to staff
This commit adds a hover effect for drag and drop in
the admin emoji uploader. It also changes the "Add New
Emoji" button to open the file selector; previously it
was useless because it was disabled unless a name was
entered (which is not even a requirement for the emoji)
and also it didn't actually do anything on click even
if it wasn't disabled.
Now we have a way of adding files without having to drag
and drop them, which is nice.
Also in this PR, there was no indication before that the upload was
complete apart from the button becoming enabled again.
This commit adds the highlight class to the emoji list
and removes it once the highlight fade animation is done,
like we do for new posts.
An admin could search for all screened ip addresses in a block by
using wildcards. 192.168.* returned all IPs in range 192.168.0.0/16.
This feature allows admins to search for a single IP address in all
screened IP blocks. 192.168.0.1 returns all IP blocks that match it,
for example 192.168.0.0/16.
* FEATURE: Remove roll up button for screened IPs
* FIX: Match more specific screened IP address first
The new warnings cover more cases and more accurate. Most of the
warnings will be visible only to staff members because otherwise they
would leak information about user's preferences.
If a theme/plugin raises an error while decorating post content, the decorator will be skipped, and the error reported on the console. Additionally, administrators will be shown a red warning at the top of the screen.
This commit refactors and re-uses some of the logic from the theme-initializer-error-reporting logic. In future, new error reports can be added by doing something like:
```
document.dispatchEvent(
new CustomEvent("discourse-error", {
detail: { messageKey: "some.translation.key", error },
})
);
```
This commit adds a check that runs regularly as per
2d68e5d942 which tests the
credentials of groups with SMTP or IMAP enabled. If any issues
are found with those credentials a high priority problem is added to the
admin dashboard.
This commit also formats the admin dashboard differently if
there are high priority problems, bringing them to the top of
the list and highlighting them.
The problem will be cleared if the issue is fixed before the next
problem check, or if the group's settings are updated with a valid
credential.
* FEATURE: hide_email_address_taken forces use of email in forgot password form
This strengthens this site setting which is meant to be used to harden sites
that are experiencing abuse on forgot password routes.
Previously we would only deny letting people know if forgot password worked on not
New change also bans usage of username for forgot password when enabled
We send the reminder using the GroupMessage class, which supports removing previous messages. We can't match them by raw because they could mention different moderators. Also, I had to change the subject to remove dynamically generated values, which is necessary for finding them.
This commit introduces a new site setting "google_oauth2_hd_groups". If enabled, group information will be fetched from Google during authentication, and stored in the Discourse database. These 'associated groups' can be connected to a Discourse group via the "Membership" tab of the group preferences UI.
The majority of the implementation is generic, so we will be able to add support to more authentication methods in the near future.
https://meta.discourse.org/t/managing-group-membership-via-authentication/175950
We don't need it anymore. Actually, I removed using of it on the client side a long time ago, when I was working on improving blank page syndrome on user activity pages (see https://github.com/discourse/discourse/pull/14311).
This PR also removes some old resource strings that we don't use anymore. We have new strings for blank pages.
We have a couple of site setting, `slow_down_crawler_user_agents` and `slow_down_crawler_rate`, that are meant to allow site owners to signal to specific crawlers that they're crawling the site too aggressively and that they should slow down.
When a crawler is added to the `slow_down_crawler_user_agents` setting, Discourse currently adds a `Crawl-delay` directive for that crawler in `/robots.txt`. Unfortunately, many crawlers don't support the `Crawl-delay` directive in `/robots.txt` which leaves the site owners no options if a crawler is crawling the site too aggressively.
This PR replaces the `Crawl-delay` directive with proper rate limiting for crawlers added to the `slow_down_crawler_user_agents` list. On every request made by a non-logged in user, Discourse will check the User Agent string and if it contains one of the values of the `slow_down_crawler_user_agents` list, Discourse will only allow 1 request every N seconds for that User Agent (N is the value of the `slow_down_crawler_rate` setting) and the rest of requests made within the same interval will get a 429 response.
The `slow_down_crawler_user_agents` setting becomes quite dangerous with this PR since it could rate limit lots if not all of anonymous traffic if the setting is not used appropriately. So to protect against this scenario, we've added a couple of new validations to the setting when it's changed:
1) each value added to setting must 3 characters or longer
2) each value cannot be a substring of tokens found in popular browser User Agent. The current list of prohibited values is: apple, windows, linux, ubuntu, gecko, firefox, chrome, safari, applewebkit, webkit, mozilla, macintosh, khtml, intel, osx, os x, iphone, ipad and mac.
Currently when a user creates posts that are moderated (for whatever
reason), a popup is displayed saying the post needs approval and the
total number of the user’s pending posts. But then this piece of
information is kind of lost and there is nowhere for the user to know
what are their pending posts or how many there are.
This patch solves this issue by adding a new “Pending” section to the
user’s activity page when there are some pending posts to display. When
there are none, then the “Pending” section isn’t displayed at all.
When this setting is turned on, it will check that normalized emails
are unique. Normalized emails are emails without any dots or plus
aliases.
This setting can be used to block use of aliases of the same email
address.
Use @here to mention all users that were allowed to topic directly or
through group, who liked topics or read the topic. Only first 10 users
will be notified.
When rendering the markdown code blocks we replace the
offending characters in the output string with spans highlighting a textual
representation of the character, along with a title attribute with
information about why the character was highlighted.
The list of characters stripped by this fix, which are the bidirectional
characters considered relevant, are:
U+202A
U+202B
U+202C
U+202D
U+202E
U+2066
U+2067
U+2068
U+2069
* FEATURE: Always show advanced invite options
The UI is more simple and more efficient than how it was when the
advanced options toggle was introduced. It does not make sense to keep
it anymore.
* UX: Minor copy edits
* UX: Merge expire invite controls
There were two controls in the create invite modal. One was a static
text that displayed how much time is left until the invite expires. The
other one was a datetime selector that set the time the invite expires.
This commit merges the two controls in a single one: staff users will
continue to see the datetime selector without the static text and
regular users will only see the static text because they cannot set
when the invite expires.
* UX: Remove invite link
It should only be visible after the invite was created.
* FEATURE: display warning when sharing a topic in a restricted category
If a topic belongs to a category that is not readable by everyone, display a text warning of "Only visible to members of groups: [group_a], [group_b]"
* DEV: Adding a new category means we need to bump this value
* DEV: pass category to showModal
* FIX: small copy fix for embedding.sample
* FIX: improve copy for site_description and short_site_description
As part of the setup wizard, improve the description of these two
strings to add context on where they will be used, so that it is
clearer how to write each one.

This commit changes the emoji uploader to use the UppyUploadMixin,
and makes some minor changes to the emoji uploader (tightening the
copy for drag and drop and adding a percentage for the upload).
Since no other uppy upload mixin components have needed to upload
multiple files so far, this necessitated adding a tracker for the
in progress uploads so we know when to reset the uploader once all
uploads are complete.
At the moment, the emoji uploader cannot be used for direct S3 uploads
because the admin emoji controller creates other records and does other
magic with the emojis. At some point we need to factor this kind of thing
into the ExternalUploadManager.transform! action to complete external
uploads.
* DEV: Sanitize HTML admin inputs
This PR adds on-save HTML sanitization for:
Client site settings
translation overrides
badges descriptions
user fields descriptions
I used Rails's SafeListSanitizer, which [accepts the following HTML tags and attributes](018cf54073/lib/rails/html/sanitizer.rb (L108))
* Make sure that the sanitization logic doesn't corrupt settings with special characters
This commit makes the following change to the Edit Bookmark
modal window for clarity:
* If the user is editing an existing bookmark without a reminder set,
hide the "none needed" option. This will draw more attention to the
delete button.
* If the user is editing an existing bookmark with a reminder set for the
future, change the "none needed" option to say "remove reminder, keep bookmark"
To do this, I needed to provide an option to override the labels
for time shortcuts in certain cases, so I could keep the NONE shortcut
but have the different wording.
Sometimes administrators want to permanently delete posts and topics
from the database. To make sure that this is done for a good reasons,
administrators can do this only after one minute has passed since the
post was deleted or immediately if another administrator does it.
Reimplemented following the revert in ce0daae636
This approach uses the global `e`/`q` shortcuts, rather than shifting focus to the `quote-button` component. The current `quoteState` is used to determine whether the quote-button is currently visible. If yes, an appEvent transmits the intention to the quote-button component. If no, the old behavior is maintained.

This reverts the new e and q shortcuts for quick-edit, and quote. The current implementation of these is causing issues with quoting on mobile devices.
We intend restore these new shortcuts soon.

We aren't translating these settings, so it makes more sense to move them into the code. I added an instance method so plugins can add mappings for custom reasons.
It allows saving local date to calendar.
Modal is giving option to pick between ics and google. User choice can be remembered as a default for the next actions.
We relied on backticks to identify and replace site setting names with links. Unfortunately, some translations don't follow this convention, breaking this feature.
Additionally, this lets us linkify `category settings` and `watched words` without using HTML in the translations.
You may notice that I split the texts we want to linkify into two groups. I did this on purpose to emphasize those that should be translated (regular_links) from those who don't (site_settings_link). If you can think of a better solution, I'm open to suggestions.
The all inboxes was introduced in
016efeadf6 but we decided to roll it back
for performance reasons. The main performance challenge here is that PG
has to basically loop through all the PMs that a user is allowed to view
before being able to order by `Topic#bumped_at`. The all inboxes was not
planned as part of the new/unread filter so we've decided not to tackle
the performance issue for the upcoming release.
Follow-up to 016efeadf6
The file size error messages for max_image_size_kb and
max_attachment_size_kb are shown to the user in the KB
format, regardless of how large the limit is. Since we
are going to support uploading much larger files soon,
this KB-based limit soon becomes unfriendly to the end
user.
For example, if the max attachment size is set to 512000
KB, this is what the user sees:
> Sorry, the file you are trying to upload is too big (maximum
size is 512000KB)
This makes the user do math. In almost all file explorers that
a regular user would be familiar width, the file size is shown
in a format based on the maximum increment (e.g. KB, MB, GB).
This commit changes the behaviour to output a humanized file size
instead of the raw KB. For the above example, it would now say:
> Sorry, the file you are trying to upload is too big (maximum
size is 512 MB)
This humanization also handles decimals, e.g. 1536KB = 1.5 MB
Allows creating a bookmark with the `for_topic` flag introduced in d1d2298a4c set to true. This happens when clicking on the Bookmark button in the topic footer when no other posts are bookmarked. In a later PR, when clicking on these topic-level bookmarks the user will be taken to the last unread post in the topic, not the OP. Only the OP can have a topic level bookmark, and users can also make a post-level bookmark on the OP of the topic.
I had to do some pretty heavy refactors because most of the bookmark code in the JS topics controller was centred around instances of Post JS models, but the topic level bookmark is not centred around a post. Some refactors were just for readability as well.
Also removes some missed reminderType code from the purge in 41e19adb0d
We don't need no stinkin' denormalization! This commit ignores
the topic_id column on bookmarks, to be deleted at a later date.
We don't really need this column and it's better to rely on the
post.topic_id as the canonical topic_id for bookmarks, then we
don't need to remember to update both columns if the bookmarked
post moves to another topic.
Administrators can use second factor to confirm granting admin access
without using email. The old method of confirmation via email is still
used as a fallback when second factor is unavailable.
In order to include the new/unread count in the browse more message
under suggested topics, a couple of technical changes have to be made.
1. `PrivateMessageTopicTrackingState` is now auto-injected which is
similar to how it is done for `TopicTrackingState`. This is done so
we don't have to attempt to pass the `PrivateMessageTopicTrackingState`
object multiple levels down into the suggested-topics component. While
the object is auto-injected, we only fetch the initial state and start
tracking when the relevant private messages routes has been hit and only
when a private message's suggested topics is loaded. This is
done as we do not want to add the extra overhead of fetching the inital
state to all page loads but instead wait till the private messages
routes are hit.
2. Previously, we would stop tracking once the `user-private-messages`
route has been deactivated. However, that is not ideal since
navigating out of the route and back means we send an API call to the
server each time. Since `PrivateMessageTopicTrackingState` is kept in
sync cheaply via messageBus, we can just continue to track the state
even if the user has navigated away from the relevant stages.
Improves the create account modal for screen readers by doing the following:
* Making the `modal-alert` section into an `aria-role="alert"` region and making it show and hide using height instead of display:none so screen readers pick it up. Made a change so the field-related error messages are always shown beneath the field.
* Add `aria-invalid` and `aria-describedby` attributes to each field in the modal, so the screen reader will read out the error hint on error. This necessitated an Ember component extension to allow both the `aria-*` attributes to be bound and to render on `{{input}}`.
* Moved the social login buttons to the right in the HTML structure so they are not read out first.
* Added `aria-label` attributes to the login buttons so they can have different content for screen readers.
* In some cases for modals, the title that should be used for the `aria-labelledby` attribute is within the modal content and not the discourse-modal-title title. This introduces a new titleAriaElementId property to the d-modal component that is then used by the create-account modal to read out the title

There are certain design decisions that were made in this commit.
Private messages implements its own version of topic tracking state because there are significant differences between regular and private_message topics. Regular topics have to track categories and tags while private messages do not. It is much easier to design the new topic tracking state if we maintain two different classes, instead of trying to mash this two worlds together.
One MessageBus channel per user and one MessageBus channel per group. This allows each user and each group to have their own channel backlog instead of having one global channel which requires the client to filter away unrelated messages.
This pull request introduces the endpoints required, and the JavaScript functionality in the `ComposerUppyUpload` mixin, for direct S3 multipart uploads. There are four new endpoints in the uploads controller:
* `create-multipart.json` - Creates the multipart upload in S3 along with an `ExternalUploadStub` record, storing information about the file in the same way as `generate-presigned-put.json` does for regular direct S3 uploads
* `batch-presign-multipart-parts.json` - Takes a list of part numbers and the unique identifier for an `ExternalUploadStub` record, and generates the presigned URLs for those parts if the multipart upload still exists and if the user has permission to access that upload
* `complete-multipart.json` - Completes the multipart upload in S3. Needs the full list of part numbers and their associated ETags which are returned when the part is uploaded to the presigned URL above. Only works if the user has permission to access the associated `ExternalUploadStub` record and the multipart upload still exists.
After we confirm the upload is complete in S3, we go through the regular `UploadCreator` flow, the same as `complete-external-upload.json`, and promote the temporary upload S3 into a full `Upload` record, moving it to its final destination.
* `abort-multipart.json` - Aborts the multipart upload on S3 and destroys the `ExternalUploadStub` record if the user has permission to access that upload.
Also added are a few new columns to `ExternalUploadStub`:
* multipart - Whether or not this is a multipart upload
* external_upload_identifier - The "upload ID" for an S3 multipart upload
* filesize - The size of the file when the `create-multipart.json` or `generate-presigned-put.json` is called. This is used for validation.
When the user completes a direct S3 upload, either regular or multipart, we take the `filesize` that was captured when the `ExternalUploadStub` was first created and compare it with the final `Content-Length` size of the file where it is stored in S3. Then, if the two do not match, we throw an error, delete the file on S3, and ban the user from uploading files for N (default 5) minutes. This would only happen if the user uploads a different file than what they first specified, or in the case of multipart uploads uploaded larger chunks than needed. This is done to prevent abuse of S3 storage by bad actors.
Also included in this PR is an update to vendor/uppy.js. This has been built locally from the latest uppy source at d613b849a6. This must be done so that I can get my multipart upload changes into Discourse. When the Uppy team cuts a proper release, we can bump the package.json versions instead.
Major changes included:
- better support for screen readers
- trapping focus in modals
- better tabbing order in composer
- alerts on no content found/number of items found
- better autofocus in modals
- mini-tag-chooser is now a multi-select component
- each multi-select-component will now display selection on one row
We've recently added a limit to the posts history modal so it displays the last 100 revisions only for performance reasons. However, the title of the modal now always says `History, last 100 revisions` even when the post has fewer than 100 revisions which can be a bit noisy.
This PR amends the history modal so the title of the modal says `History` when the post's revisions count is ≤100, and `History, last 100 revisions` when it has more >100 revisions.
When a user signs up via an external auth method, a new link is added to the signup modal which allows them to connect an existing Discourse account. This will only happen if:
- There is at least 1 other auth method available
and
- The current auth method permits users to disconnect/reconnect their accounts themselves
This handles a few edge cases which are extremely rare (due to the UI layout), but still technically possible:
- Ensure users are authenticated before attempting association.
- Add a message and logic for when a user already has an association for a given auth provider.
This reverts a part of changes introduced by https://github.com/discourse/discourse/pull/13947
In that PR I:
1. Disallowed topic feature links for TL-0 users
2. Additionally, disallowed just putting any URL in topic titles for TL-0 users
Actually, we don't need the second part. It introduced unnecessary complexity for no good reason. In fact, it tries to do the job that anti-spam plugins (like Akismet plugin) should be doing.
This PR reverts this second change.
This disallows putting URLs in topic titles for TL0 users, which means that:
If a TL-0 user puts a link into the title, a topic featured link won't be generated (as if it was disabled in the site settings)
Server methods for creating and updating topics will be refusing featured links when they are called by TL-0 users
TL-0 users won't be able to put any link into the topic title. For example, the title "Hey, take a look at https://my-site.com" will be rejected.
Also, it improves a bit server behavior when creating or updating feature links on topics in the categories with disabled featured links. Before the server just silently ignored a featured link field that was passed to him, now it will be returning 422 response.
Discourse automatically sends a private message after backup or
restore finished. The private message used to contain the log inline
even when it was very long. A very long log can create issues because
the length of the post will be over the maximum allowed length of a
post. When that happens, Discourse will try to create an upload with
the logs. If that fails, it will trim the log and inline it.
This adds a few different things to allow for direct S3 uploads using uppy. **These changes are still not the default.** There are hidden `enable_experimental_image_uploader` and `enable_direct_s3_uploads` settings that must be turned on for any of this code to be used, and even if they are turned on only the User Card Background for the user profile actually uses uppy-image-uploader.
A new `ExternalUploadStub` model and database table is introduced in this pull request. This is used to keep track of uploads that are uploaded to a temporary location in S3 with the direct to S3 code, and they are eventually deleted a) when the direct upload is completed and b) after a certain time period of not being used.
### Starting a direct S3 upload
When an S3 direct upload is initiated with uppy, we first request a presigned PUT URL from the new `generate-presigned-put` endpoint in `UploadsController`. This generates an S3 key in the `temp` folder inside the correct bucket path, along with any metadata from the clientside (e.g. the SHA1 checksum described below). This will also create an `ExternalUploadStub` and store the details of the temp object key and the file being uploaded.
Once the clientside has this URL, uppy will upload the file direct to S3 using the presigned URL. Once the upload is complete we go to the next stage.
### Completing a direct S3 upload
Once the upload to S3 is done we call the new `complete-external-upload` route with the unique identifier of the `ExternalUploadStub` created earlier. Only the user who made the stub can complete the external upload. One of two paths is followed via the `ExternalUploadManager`.
1. If the object in S3 is too large (currently 100mb defined by `ExternalUploadManager::DOWNLOAD_LIMIT`) we do not download and generate the SHA1 for that file. Instead we create the `Upload` record via `UploadCreator` and simply copy it to its final destination on S3 then delete the initial temp file. Several modifications to `UploadCreator` have been made to accommodate this.
2. If the object in S3 is small enough, we download it. When the temporary S3 file is downloaded, we compare the SHA1 checksum generated by the browser with the actual SHA1 checksum of the file generated by ruby. The browser SHA1 checksum is stored on the object in S3 with metadata, and is generated via the `UppyChecksum` plugin. Keep in mind that some browsers will not generate this due to compatibility or other issues.
We then follow the normal `UploadCreator` path with one exception. To cut down on having to re-upload the file again, if there are no changes (such as resizing etc) to the file in `UploadCreator` we follow the same copy + delete temp path that we do for files that are too large.
3. Finally we return the serialized upload record back to the client
There are several errors that could happen that are handled by `UploadsController` as well.
Also in this PR is some refactoring of `displayErrorForUpload` to handle both uppy and jquery file uploader errors.
