## Issue
The TUS client automatically removes the upload fingerprint whenever there is a 4xx error. When we try to resume later, we couldn't find the the fingerprint and ended up creating a new upload ID.
## Changes
Since we are also storing the uploadUrl ourselves, provided that to override the tus client's default behavior of restarting a new session on 4xx errors.
The stalling behavior has changed a bit, probably with the removal of CF.
The stall difference between 10MB and 50MB is not too noticable, so picking 25MB as a start.
## Issue
The status = 0 is due to unresponsive backend right after the tus-upload. No root-cause found yet.
## Change
It may or may not help, but adding a delay to account for the unresponsive stage for now.
## Issue/Steps
From Randy:
- started the upload then open a new tab of the same page
- one of the tab finished the upload and successfully published the file, and the other tab received 404 error on patch and head request, because the file is already removed on the server
## Changes
Use the default onRetry code that ignores all 4xx, except for LOCKED and CONFLICT. Had to duplicate some code from tus because I still need to inject the 'retry' progress for the GUI to update the string.
## Issue
If you make 2 claims from the same source file, the second upload thinks it's trying to resume from the first one. They should be unique uploads.
## Approach
Stash the upload url for comparison when looking up existing uploads to resume.
Stash that in `params` to minimize code changes. We'll just need to ensure it is cleared before we generate the SDK payload.
* Publish button: use spinner instead of "Publishing..."
Looks better, plus the preview could take a while sometimes.
* Refactor `doPublish`. No functional change
This is to allow `doPublish` to accept a custom payload as an input (for resuming uploads), instead of always resolving it from the redux data.
* Add doPublishResume
* Support resume-able upload via tus
## Issue
38 Handle resumable file upload
## Notes
Since we can't serialize a File object, we'll need to the user to re-select the file to resume.
* Exclude "modified date" for Firefox/Android
## Issue
It appears that the modification date of the Android file changes when selected, so that file was deemed "different" when trying to resume upload.
## Change
Exclude modification date for now. Let's assume a smart user.
* Move 'currentUploads' to 'publish' reducer
`publish` is currently rehydrated, so we can ride on that and don't need to store the `currentUploads` in `localStorage` for persistence. This would allow us to store Markdown Post data too, as `localStorage` has a 5MB limit per app.
We could have also made `webReducer` rehydrate, but in this repo, there is no need to split it to another reducer. It also makes more sense to be part of publish anyway (at least to me).
This change is mostly moving items between files, with the exception of
1. An additional REHYDRATE in the publish reducer to clean up the tusUploader.
2. Not clearing `currentUploads` in CLEAR_PUBLISH.
* Restore v1 code for livestream replay, etc.
v2 (tus) does not handle `remote_url`, so the app still needs v1 for that. Since we'll still have v1 code, use v1 for previews as well.
