Software update can cause appearance of system freeze

[dfarning]

In my setting -> Software update the system can appear freeze forever if the system can not connect to the network.

So:

1. Should we add a timeout to the updating process while it is checking for updates?

and/or

2. Display something like 'Please be patient, this can take several seconds' message while it is checking for updates?

Ah! misread the ticket :(

I guess we should just display that: 'Cannot check for updates, please check your internet connection' or something similar...

For upstream as well, it doesn't display any messages to indicate that updating failed. It just says 'Your software is up to date' which is incorrect. Simon?

The patch "0001-sl-3195-Same-behaviour-of-cancel-buttons-in-Software.patch" (ticket sl#3195), along with "0002-sl-3194-Notify-user-of-connection-not-available-in-S.patch", can be tested as follows ::

a. Disconnect any network.

b. Go to Software-Update.

c. Since the network is not outright available, the message "Cannot check for updates. Please

check your internet connection, and try running Software Update again" will appear.
Now, the only way to restart the operation is that user goes out, and re-enters the Software-
Update section.

d. Come out of the Software-Update section.

e. Connect to the network.

f. Go to Software-Update.

g. Now, the "Checking for updates" message should appear, and operation should proceed.

h. If "Cancel" is clicked anytime, it will have the same effect, as the "X" button on the toolbar (in this case, exit from the section-view).

i. One particular use-case -- if the network is available at the start, but goes out midway, then the user will be stuck at "Checking for updates" message. Following two things may then happen ::

(i) network returns after some time -- Then, the operation WILL proceed to completion (confirmed by testing).

(ii) network does not return -- The same message "Checking for updates" will continue to be seen. User may exit (by clicking "cancel", or "X").

Dextrose-3 no longer ships its own microformat updater in the immediate term, rather ships the OLPC updater. Reducing severity:priority.
