Change subject: webadmin,userportal: Improve the way logging works ...................................................................... webadmin,userportal: Improve the way logging works 1. all logging related code extracted into ApplicationLogManager 2. added "error is effectively the same as last one" detection: * on 1st occurence, error is logged as "Uncaught exception" * on 2nd occurence, error is logged as "Uncaught exception (2x)" * same message for any further occurences of the same error 3. error is remotely logged ONLY if both of following are true: * application (browser) window has focus * current error is NOT effectively the same as last one An error E1 is effectively the same as error E2 if and only if E1's stack trace has the same length as E2's stack trace and the stack trace elements are equal at any given index. Due to how GWT emulates java.lang.StackTraceElement, we're using StackTraceElement.toString() to capture all important info: declaringClass methodName fileName lineNumber Change-Id: I66c3c5c4ca2451403d1cdd8d29cca4823a90f4f2 Bug-Url: https://bugzilla.redhat.com/1358136 Signed-off-by: Vojtech Szocs <vszocs(a)redhat.com&gt; --- M frontend/webadmin/modules/gwt-common/src/main/java/org/ovirt/engine/ui/common/gin/BaseSystemModule.java A frontend/webadmin/modules/gwt-common/src/main/java/org/ovirt/engine/ui/common/logging/ApplicationLogManager.java M frontend/webadmin/modules/gwt-common/src/main/java/org/ovirt/engine/ui/common/system/ApplicationFocusManager.java M frontend/webadmin/modules/gwt-common/src/main/java/org/ovirt/engine/ui/common/system/BaseApplicationInit.java M frontend/webadmin/modules/userportal-gwtp/src/main/java/org/ovirt/engine/ui/userportal/system/ApplicationInit.java M frontend/webadmin/modules/webadmin/src/main/java/org/ovirt/engine/ui/webadmin/system/ApplicationInit.java 6 files changed, 149 insertions(+), 54 deletions(-) Approvals: Alexander Wels: Looks good to me, approved Jenkins CI: Passed CI tests Vojtech Szocs: Verified -- To view, visit https://gerrit.ovirt.org/61414 To unsubscribe, visit https://gerrit.ovirt.org/settings Gerrit-MessageType: merged Gerrit-Change-Id: I66c3c5c4ca2451403d1cdd8d29cca4823a90f4f2 Gerrit-PatchSet: 2 Gerrit-Project: ovirt-engine Gerrit-Branch: ovirt-engine-4.0.2 Gerrit-Owner: Vojtech Szocs <vszocs(a)redhat.com&gt; Gerrit-Reviewer: Alexander Wels <awels(a)redhat.com&gt; Gerrit-Reviewer: Jenkins CI Gerrit-Reviewer: Oved Ourfali <oourfali(a)redhat.com&gt; Gerrit-Reviewer: Piotr Kliczewski <piotr.kliczewski(a)gmail.com&gt; Gerrit-Reviewer: Tal Nisan <tnisan(a)redhat.com&gt; Gerrit-Reviewer: Vojtech Szocs <vszocs(a)redhat.com&gt; Gerrit-Reviewer: gerrit-hooks <automation(a)ovirt.org&gt;
