Merge lp:~mcveat/tomdroid/loggers-cleanup into lp:~tomdroid-maintainers/tomdroid/main

[Piotr Adamski]

[Koichi Akabe (vbkaisetsu)]

Hello Piotr,

"if (Tomdroid.LOGGING_ENABLED)"s are written for all Log.xxx functions.

It is repetitious.
I think it will be more simpler if you create functions which check Tomdroid.LOGGING_ENABLED and use Log.xxx.

Koichi Akabe

Bu then, would the debug Strings be created every time, even when logging is
not enabled ?

check this:

[quote]
*The guard statement (checking isDebugEnabled()) is there to prevent
potentially expensive computation of the log message*
...
*Better yet is to use a more up-to-date logging framework where the log
statements take a format string and a list of arguments to be substituted by
the formatter—but "lazily," only if the logger is enabled. This is the
approach taken by
slf4j<http://www.slf4j.org/apidocs/org/slf4j/Logger.html#debug%28java.lang.String,%20java.lang.Object%5B%5D%29>

Current logging frameworks ensure sure that debug Strings are not
concatenated unless debug is enabled. I'm not sure how to do that in
Android, you may need to code this mini-framework yourself...

Alex

I was also concerned about that.

Should be pretty straightforward, yet not so versatile with use of
java.text.MessageFormat and varargs. I'll try how it rolls this
evening.

256. By Piotr Adamski on 2011-10-27

excluded turning off logging logic to separate clas TLog

257. By Piotr Adamski on 2011-10-27

merged with main

258. By Piotr Adamski on 2011-10-27

updated license note

259. By Piotr Adamski on 2011-10-27

removed forgotten debug statements

[Piotr Adamski (mcveat)]

I've implemented simple logging utility that should remove the boilerplate code of checking logging switch state, yet avoiding unnecessary string concatenations. Tell what you think about it.

[Koichi Akabe (vbkaisetsu)]

I think it is great work!!

[Olivier Bilodeau (plaxx)]

Good stuff! Thanks! Next time try not to re-organize imports please. Makes patches larger than they should be and merging more complicated.

review: Approve

[Olivier Bilodeau (plaxx)]

Turns out I needed to make additional changes. See https://code.launchpad.net/~tomdroid-dev/tomdroid/loggers-cleanup if you are interested.
