[pve-devel] [PATCH proxmox_dart_api_client/pve_flutter_frontend_null 0/2] fix #4976

[Alexander Abraham]

This patches fixes bug 4976 in which the UI for nodes that are
offline was reporting a "null" error. In the API client, error-handling
for POST requests was changed to be more explicit and in the app's UI
the case of a node suddenly being offline was handled. Viewing the
information for a node that is offline was made impossible.

Hi, thanks for tackling this. Noticed a few small things. Find the 
comments inline. Generally, please run dart format on these changes. 
Every changed block contains wrong indentation. Also, the commit message 
needs to be fixed.

Is there a reason this is not wrapped in a ProxmoxApiException? If the 
reason is that it then displays "Host unreachable, possibly offline. -> 
null", I think it would generally be a good idea to adapt 
ProxmoxApiException's toString method to account for the details 
possibly being null.

nit: Since this is not a sentence, I think it should either be "Host is 
unreachable, possibly offline" or not end with a dot.

Just wanted to add that I sent a patch for adapting
ProxmoxApiException's toString method since I encountered this problem
elsewhere as well:

[pve-devel] [PATCH flutter_frontend 1/1] fix #4976: ui: Nodes offline

[Alexander Abraham]

This commit adds functionality for not letting users click on nodes
that are offline in the general overview screen. Furthermore,
functionality was added to send the user back to the general overview
screen if a node is suddenly offline while the user is viewing
information on that node.

Re: [pve-devel] [PATCH flutter_frontend 1/1] fix #4976: ui: Nodes offline

[Michael Köppl]

The commit message is not very descriptive. Also, please run dart format 
on these changes. There are some wrong indentations, missing spaces, 
trailing spaces, etc. I also added 3 comments inline.

Apart from that, I tested this by manually stopping a node I was 
currently looking at in the node overview. The app navigates me back to 
the previous screen once it detects that the node is offline and 
afterwards stops me from opening that node's overview again while it is 
offline. Opening the overview once the node is online again works as 
well. Everything seems to work as expected. It's a good change, well done!

Instead of navigating back immediately, I think it would make sense to 
instead display an AlertDialog, showing the error message to the user 
and letting them leave the screen through a "Close" button in the 
dialog. Otherwise, it feels a bit like the app is taking control away 
from the user. We use this approach in other places in the app (e.g. . 
What do you think?

Wrapping the whole block in a try-catch without a rethrow also means 
that users will be navigated back to the home screen without an error 
message if e.g. the getNodeDisksList call returns an error. I think it'd 
make sense to rethrow here, similar to above.

This does not seem to be related to the issue? The subscription dialog 
cannot be opened anymore with this change.

nit: I think "Node is offline" would feel more polished. Or it should 
not have a period, since it's not a sentence.
