Red Hat Bugzilla – Bug 1334954
UI freezes with a spinning logo forever
Last modified: 2018-04-17 03:47:20 EDT
Created attachment 1155898 [details] logs and screenshot Description of problem: I randomly pressed the sort buttons on the columns in the tables listing the container projects and the screen froze. I managed to reproduce it again by doing the same thing. Looking in inspect elements it seems that every time it freezes there is an api request. Version-Release number of selected component (if applicable): cfme-5.6.0.5-beta2.4.1.el7cf.x86_64 How reproducible: 100% Steps to Reproduce: 1. in the projects page (compute -> containers -> projects) randomly press the headline of the different columns to sort the objects. 2. 3. Actual results: after about 30 seconds the screen would freeze I noticed that every time it happens its when an api request is sent. Expected results: screen should not freeze. Additional info: logs and screen shots
Dan it seems a race between the "/container_project/show_list?sortby=X" request and the "/api" request. Is the recurring "/api" request (every minute) involving somehow the spinner? On the backend side it seems all OK: [----] I, [2016-05-10T18:29:30.369305 #3032:176bc30] INFO -- : Started POST "/container_project/show_list?sortby=4&" for 127.0.0.1 at 2016-05-10 18:29:30 -0400 [----] I, [2016-05-10T18:29:30.370706 #3032:176bc30] INFO -- : Processing by ContainerProjectController#show_list as JS [----] I, [2016-05-10T18:29:30.370771 #3032:176bc30] INFO -- : Parameters: {"sortby"=>"4"} [----] I, [2016-05-10T18:29:30.621176 #3032:176bc30] INFO -- : Rendered layouts/_flash_msg.html.haml (0.1ms) [----] I, [2016-05-10T18:29:30.621943 #3032:176bc30] INFO -- : Rendered layouts/_info_msg.html.haml (0.1ms) [----] I, [2016-05-10T18:29:30.622050 #3032:176bc30] INFO -- : Rendered layouts/listnav/_show_list.html.haml (0.3ms) [----] I, [2016-05-10T18:29:30.622135 #3032:176bc30] INFO -- : Rendered layouts/_listnav.html.haml (0.5ms) [----] I, [2016-05-10T18:29:30.625673 #3032:176bc30] INFO -- : Rendered layouts/_list_grid.html.haml (3.2ms) [----] I, [2016-05-10T18:29:30.627436 #3032:176bc30] INFO -- : Rendered layouts/_pagingcontrols.html.haml (0.8ms) [----] I, [2016-05-10T18:29:30.632972 #3032:176bc30] INFO -- : Completed 200 OK in 262ms (Views: 7.6ms | ActiveRecord: 0.0ms) [----] I, [2016-05-10T18:29:32.618952 #3032:176a0c4] INFO -- : Started POST "/container_project/show_list?sortby=2&" for 127.0.0.1 at 2016-05-10 18:29:32 -0400 [----] I, [2016-05-10T18:29:32.620441 #3032:176a0c4] INFO -- : Processing by ContainerProjectController#show_list as JS [----] I, [2016-05-10T18:29:32.620525 #3032:176a0c4] INFO -- : Parameters: {"sortby"=>"2"} [----] I, [2016-05-10T18:29:32.944180 #3032:176a0c4] INFO -- : Rendered layouts/_flash_msg.html.haml (0.1ms) [----] I, [2016-05-10T18:29:32.945000 #3032:176a0c4] INFO -- : Rendered layouts/_info_msg.html.haml (0.1ms) [----] I, [2016-05-10T18:29:32.945099 #3032:176a0c4] INFO -- : Rendered layouts/listnav/_show_list.html.haml (0.3ms) [----] I, [2016-05-10T18:29:32.945188 #3032:176a0c4] INFO -- : Rendered layouts/_listnav.html.haml (0.6ms) [----] I, [2016-05-10T18:29:32.948945 #3032:176a0c4] INFO -- : Rendered layouts/_list_grid.html.haml (3.4ms) [----] I, [2016-05-10T18:29:32.950697 #3032:176a0c4] INFO -- : Rendered layouts/_pagingcontrols.html.haml (0.9ms) [----] I, [2016-05-10T18:29:32.956350 #3032:176a0c4] INFO -- : Completed 200 OK in 336ms (Views: 7.9ms | ActiveRecord: 0.0ms) [----] I, [2016-05-10T18:29:33.327316 #3045:174079c] INFO -- : Started GET "/api" for 127.0.0.1 at 2016-05-10 18:29:33 -0400 [----] I, [2016-05-10T18:29:33.357161 #3045:174079c] INFO -- : Processing by ApiController#show as JSON [----] I, [2016-05-10T18:29:33.484713 #3045:174079c] INFO -- : Completed 200 OK in 127ms (Views: 0.5ms | ActiveRecord: 0.0ms) [----] I, [2016-05-10T18:30:32.733013 #3045:17404e0] INFO -- : Started GET "/api" for 127.0.0.1 at 2016-05-10 18:30:32 -0400 [----] I, [2016-05-10T18:30:32.756148 #3045:17404e0] INFO -- : Processing by ApiController#show as JSON [----] I, [2016-05-10T18:30:32.876420 #3045:17404e0] INFO -- : Completed 200 OK in 120ms (Views: 0.5ms | ActiveRecord: 0.0ms) So I tend to believe that it's some race in the frontend.

verified on cfme-5.6.0.8-rc1.1.el7cf.x86_64 I had other requests running during api call and UI did not freeze.
