Whenever bulk updates are done in wp-admin/update-core.php, no feedback is given, until all updates are done

[bedas]

This bug exists since I know WP, and it still persists on the latest version.

1. Go to wp-admin/update-core.php
2. Check all boxes for pending updates
3. Click update

• The page reloads.
• Nothing happens. The page just stays grey (admin bar etc are there, but the page itself is empty)
• After a while, which can be a very long while if a lot of updates are pending, the screen gets populated (without page reload) with log like

  
  The update process is starting. This process may take a while on some hosts, so please be patient.
  
  Enabling Maintenance mode…
  
  Updating Plugin {Plugin name} (1/12)
  
  {Plugin name} updated successfully. Show details.
  Updating Plugin {Plugin name} 
  
  [etc]
  All updates have been completed.
  
  Go to Plugins page | Go to WordPress Updates page
  
  

This log clearly should happen _while_ it is updating, and not once it is done.
There is no spinner, no feedback, nothing that tells the user "something is working"

I personally agree with this.
At least, the first sentence of that log should appear to start.

Saying that... I find this also extremely silly:

{Plugin name} updated successfully. Show details.
Updating Plugin {Plugin name}

Why does it show "Updating plugin" underneath the "show details". That should be only for errors imho. But that might be a whole other ticket maybe.

I had coworkers who help me to maintain my websites say: "Are the updates actually running or not?"
So, I 100% agree.

Also, this log would a nice place for @afragen to hook the rollback into when plugin/theme updates cause errors.

@NekoJonez you should try the Rollback Update Failure feature plugin. It really is hooked and works for both manual and auto updates. 😉

It maybe was not clear in my report, but there in an [etc] below this:

<?php
{Plugin name} updated successfully. Show details.
Updating Plugin {Plugin name} 

Actually what you see _after_ the updates are done is basically a list/flow of

• updating plugin X
• plugin X updated
• updating plugin Y
• updated plugin Y
• etc

And that is good! But, it should show _while_ this happens and not once it's done.
This is bug, not an enhancement, just to clarify - because clearly the log is intended to be shown in real time and not after the facts.
