[jira] Created: (OFBIZ-1169) Eliminate redundant log messages in
screen widgets
Eliminate redundant log messages in screen widgets
--------------------------------------------------
Key: OFBIZ-1169
URL: https://issues.apache.org/jira/browse/OFBIZ-1169
Project: OFBiz
Issue Type: Improvement
Components: framework
Affects Versions: SVN trunk
Reporter: Leon Torres
Fix For: SVN trunk
Currently, if you have a typo or minor bug in a bsh or ftl file that is part of a screen widget definition, the resulting error message in the log and on screen can be overwhelming. This causes a serious usability issue with developers and new users.
I decided to spend some personal time to see what the source of the log "explosion" is and how it can be fixed.

Sorry Leon,
I added "log4r.logger.org.ofbiz.base.util=OFF" in debug.properties. I still can't see any differences

Yes, please test. It's pretty easy to: just introduce typos into the FTL and bsh files and see what shows up in the log and on screen. :-)

[jira] Updated: (OFBIZ-1169) Eliminate redundant log messages in
screen widgets
Posted by "Leon Torres (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/OFBIZ-1169?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Leon Torres updated OFBIZ-1169:
-------------------------------
Attachment: screenwidget-log-fix.patch
This patch provides two major improvements to the readability of screen widget logs.
1. The render screen function is recursive in nature, and each render step will log every error. Most of these errors get thrown up to the previous render function, which causes them to get logged again. This is the primary reason that the log file explodes with messages.
To fix it, I introduced a special exception called ScreenRenderException which tells the rendering function that the particular error was already caught and logged, so it can just pass it up the chain.
2. HtmlWidget.java was throwing a RuntimeException, which pollutes the user's screen with a lot of error information. Instead of throwing RuntimeException, just render the error message directly to the screen. This is much more useful as it prints exactly what the error was and nothing more, allowing you to fix typos in the FTL much faster.

Leon,
Generally this is a great helper and has significantly cut down on the error messages thrown. However, one problem is that the exception message no longer tells you the full location of the file. For example, I get this:
2007-07-25 16:26:15,598 (http-0.0.0.0-8433-Processor4) [ Log4JLoggerFactory.java:96 :ERROR]
Expression haha is undefined on line 64, column 31 in viewprofile.ftl.
The problematic instruction:
----------
==> ${haha} [on line 64, column 29 in viewprofile.ftl]
----------
Java backtrace for programmers:
----------
freemarker.core.InvalidReferenceException: Expression haha is undefined on line 64, column 31 in viewprofile.ftl.
But which viewprofile.ftl? It would be helpful if it could say component://.../viewprofile.ftl

Oops, forgot to svn add the ScreenRenderException so I can diff it. The second patch contains the new exception file, which is simply a subclass of GeneralException.

For anything like this please allow at least a couple of days for review before committing. If it was an urgent bug fix or something that would be different, but with a little time more of the general group using OFBiz might be able to review, comment on, and help improve this.

Oh yeah, I forgot to mention that BshUtil.java is a little noisy, because it both logs the exception and throws it, causing redundant messages. I just shut it off in debug.properties:
log4r.logger.org.ofbiz.base.util=OFF
Try this patch with this logger setting and it should be more concise. :-)
