Ciao,
I have a situation where some requests may take a long time, resulting in the
user getting impatient and triggering the request again. If the second
request cannot get the lock while the first is processing, the request
processing loop retries for a total of 10 attempts before giving up.
(This is especially critical when the default #retryDelays of 23.31 seconds
is too long and have been shortened.)
Short of fixing the thing that takes a ridiculously long time, what can I do
to prevent or ignore the user triggering the request a second time and
perhaps getting back a /Too many retries: 11/ response instead of what was
requested?
Is there a way to disable the UI while a request is being processed?
Is there a way to produce a "null response" that won't try to update the
display in the browser?
My solution:
When i render the anchor where relative requests may take a long time
i do:
html div with:[
self renderSomeDataToDisplayOn:html. " data user informations "
"A" self renderHiddenBarOn: html.
"B" self renderCommandOn: html
Where:
A) i render a hidden progress "widget"
self renderHiddenBarOn: html.
html div id: 'prgDiv' ;
class:'loader';
style:'display: none; margin: 5px auto;'.
2) self renderCommandOn: html
html div id: ( self divReferencePrefix: 'cmdDiv' for: self ); class: 'command'; with:[
html anchor
callback:[ | aBlock | ];
onClick: ( self onClickUpdateFor: self on: html);
title: 'title;
with: 'Anchor for a long time requestA'.
html anchor ............
2A ) the onClickUpdateFor: self on: html
^( html jQuery ajax
script: [ :s |
s << (( s jQuery class: 'command' ) hide ).
s << (( html jQuery: ( 'prgDiv' )) show) ])
When the user click on the anchor the system display a progress bar and hidden all the other command.
The browser appears to be locked until it receives the response from the server.
And what were you looking for?
How much report is a summary, but I think there is everything to try.
Eventually let me know.
Ciao,
Dario
