Description Einav Cohen 2015-01-07 18:19:37 UTC

+++ This bug was initially created as a clone of Bug #1179862 +++

This RFE applies to both WebAdmin & UserPortal.

During GWT application compilation, symbol maps (mapping from Java identifier to obfuscated JavaScript identifier) are produced as *.symbolMap files, located in following directories:

  frontend/webadmin/modules/webadmin/target/generated-gwt/WEB-INF/deploy/webadmin/symbolMaps
  frontend/webadmin/modules/userportal-gwtp/target/generated-gwt/WEB-INF/deploy/userportal/symbolMaps

These symbol maps can be very helpful when facing client-side errors manifested as obfuscated JavaScript stacktraces. Even though these symbol maps are not 100% accurate (see [1] for details), they are still a very good starting place.

[1] https://code.google.com/p/google-web-toolkit/wiki/SourceMaps (see "Details" section describing symbol maps)

Without using symbol maps, one has to compile GWT application in "draft" mode [2] and reproduce the problem on this "draft" application. Replacing "normal" GWT application with its "draft" version can be, however, problematic (especially in case the customer is the only one able to reproduce the error).

[2] http://www.ovirt.org/DebugFrontend#GWT_Draft_Compile

Symbol maps can be considered as meta-data bundled in WebAdmin & UserPortal rpm package.

Any other patch needed or can we move this to modified and clone to ZStream?

not that I am aware of.

Comment 3 Alon Bar-Lev 2015-01-14 09:22:37 UTC

if this is downstream 3.5.1 it will take the commit from upstream anyway... I am unsure why this bug is required.

AFAIK: if we want it in 3.4.z, we must ensure that it is fixed in 3.5(.z) first, hence this bug is needed.
