Add method trace capability

[greenlaw110]

new configuration: betterlogs.trace.level.

new behavior:

1. when betterlogs.trace.level is equal or higher than application.log then enhance the source code so that on entry/exit(every return) of each application class methods body will be logged.
2. when betterlogs.trace.mode set to NOTRACE, then only class/method/constructors explicitly marked with @trace annotation will be trace enhanced; if betterlogs.trace.mode set to TRACE, the all methods/contructors will be trace enhanced unless they are annotated with @notrace
3. in the log info add thread ID information. Previous:

• 11:04:18,625 INFO ~ [/app/controllers/Config.java:83] after() :: enter after
  Now:
  11:04:18,625 INFO ~ [/app/controllers/Config.java:83|17] after() :: enter after

Where "17" is the current thread ID

The documentation has been updated

Trace now support trace theme:

Call BetterLogsPlugin.setTraceThemes("order_process", "user_register", ...); to set current trace theme to be output

on your application methods, set trace theme(s);
@trace("order_process") public void orderForm(...) {...};
@trace("user_register") public void register(...) {...}

Hi,

Thanks for the pull request. Sorry for the delay.

Anyway, there are some problems :

• your code relies on javassist >= 3.11 (javassist is 3.9 in play 1.2.2 ; since it is a 'sensible' dependency for the framework, BetterLogs should not depend on another javassist version)
• please, do not change tab/spaces indentation. All tabs have been converted to spaces, so git considers that almost all lines of code have been altered
• can you document what "themes" stand for ?

Thanks in advance,

Stephane

Hi,

The code updated to support javassist 3.9, and document updated with more information about trace theme.

However no changes has been made to the tab/space issue. I've used eclipse auto format to reformat all source code. And because the updates itself are even bigger than original betterlogs code. It's more like a complete rewrite than adding a few lines for bug fix or enhancement. Maybe you want to check it and replace the existing code base.

Thanks,
Green
