## Issue
534 prevent new channel creation over x channels
## Notes
Also handled from the API call (`doCreateChannel`) in case there are other UI components that create channels.
- Move stickers and emojis to a single menu comment-selectors on both mobile and desktop
- More style improvements
- Some fixes
- Fix livechat scrolling
In 36fe7366, the approach to fix the "missing chunk" error and user using old code was to disable caching on the html so that user always grabs the one that's pointing to the latest ui.js.
But https://cristian.sulea.net/blog/disable-browser-caching-with-meta-html-tags/ says 3 sets of `meta` is needed to, and we missed out one. That probably explains why refreshing sometimes does not work, although I've also read that some browsers simply ignores these meta.
- Put back the "--end--" entry to cover the "no trailing comma" part. This would reduce mistakes and also reduce diffs on the comma part.
- Updated with new strings; deleted some unused ones.
## Ticket
426
## Issue
Currently, we check if we have any existing claims with the same name when uploading, i.e. "lbry://<name>". It does not include claims that you are still uploading, so you might end up with duplicate claims.
In the ticket, there is also the issue of 2 uploads sharing the same slot, causing the progress indicator to jumpy between the uploads. That has been fixed by using a guid instead of using `name`.
## Aside
I think there is another request to allow the same name but on different channel ... next time, next time ....
* Upload: fix redux key clash
## Issue
`params` is the "final" value that will be passed to the SDK and `channel` is not a valid argument (it should be `channel_name`). Also, it seems like we only pass the channel ID now and skip the channel name entirely.
For the anonymous case, a clash will still happen when since the channel part is hardcoded to `anonymous`.
## Approach
Generate a guid in `params` and use that as the key to handle all the cases above. We couldn't use the `uploadUrl` because v1 doesn't have it.
The old formula is retained to allow users to retry or cancel their existing uploads one last time (otherwise it will persist forever). The next upload will be using the new key.
* Upload: add tab-locking
## Issue
- The previous code does detect uploads from multiple tabs, but it was done by handling the CONFLICT error message from the backend. At certain corner-cases, this does not work well. A better way is to not allow resumption while the same file is being uploading from another tab.
- When an upload from 1 tab finishes, the GUI on the other tab does not remove the completed item. User either have to refresh or click Cancel. Clicking Cancel results in the 404 backend error. This should be avoided.
## Approach
- Added tab synchronization and locking by passing the "locked" and "removed" information through `localStorage`.
## Other considered approaches
- Wallet sync -- but decided not to pollute the wallet.
- 3rd-party redux tab syncing -- but decided it's not worth adding another module for 1 usage.
* Upload: check if locked before confirming delete
## Reproduce
Have 2 tabs + paused upload
Open "cancel" dialog in one of the tabs.
Continue upload in other tab
Confirm cancellation in first tab
Upload disappears from both tabs, but based on network traffic the upload keeps happening.
(If upload finishes the claim seems to get created)
* Settings Page: add warning for unsaved settings
## Issue
When entering Settings Page, sync-loop is disable until user exist Settings Page. If browser is closed, changes will be lost.
## Change
Add the usual browser-level modal popup.
Note that all modern browsers have stopped supporting customized messages, but I still left the message there for clarity. Tried to use our own toast for it, but the handler locks all GUI until it is serviced.
* app: remove unused props
* app: use lighter selectors
When all we need is to know if something exists or their count, use the ID version instead of the url/claim version to avoid the heavy transformation.
* SyncFatalError: show nag instead of hard-crashing.
## Issue
When sync fails, we crash the app.
## Ticket
Maybe closes 39 "Better handle both internal and web backend interruptions / downtime"
## Approach
I'm tackling this from the standpoint that (1) sync errors are not that fatal -- we'll just lost a few recent changes (2) network disconnection is the common cause.
## Changes
- If we are offline:
- Inform user through a nag. All other status is meaningless if we are offline.
- If we are online:
- If api is STATUS_DOWN, show the existing crash page.
- If there is a sync error, show a nag saying settings are now potentially unsynchronized, and add a button to retry sync.
- If there is a chunk error, nag to reload.
* Attempt to detect `status=DOWN`
Previous code resolves the status to either "ok" or "not", which makes the app unable to differentiate between the "degraded" (nag) and "down" (crash) states.
