Thanks the patch! I'm really surprised at all function has following lines and the method name is hard coded. If you'd like to output log in begging and ending of methods, we should implement decorator for outputting log and use the decorator.

msg = BEGIN function-name: with arguments
LOG.debug(msg)

msg = END function-name
LOG.debug(msg)

Hi Muroi,

Thank you for your comment. I fix my code.

rkmrHonjo commented 8 years ago

Hi @muroi ,

I fixed my code in accordance with your comments. (If I should squash two commits, please point out.)

P.S. I didn't remove logs from _get_vm_param(). Your comment is basically right. But _get_vm_param() will retry do_instance_show() if it is failed. It doesn't just call rc_util_api.do_instance_show().

Thanks for updating. Overall the codes looks good. Great job!

I still have some questions. please check the inline comments.

rkmrHonjo commented 8 years ago

Thank you for your re-comments. I check those & fix my code.

muroi commented 8 years ago

Oops, I forgot commenting an important stuff. The decorator method needs wraps[1] decorator.

Oh...Thank you for pointing out.

Hi @muroi ,

Sorry for taking long to fix my code. Please check new commit.

rkmrHonjo commented 8 years ago

Hi @muroi ,

I rethought about my code for logging thread name. Then I understood that my most recent patch is not good.

My fix plan is following:

Sorry, I noticed that thread name is already contained in log record object!
If we specify "%(threadName)s" in logging format string, we'll be able to output thread name to log.
So I'll remove the class that is inherited RequextContext.
It is unnecessary.
And I'll add "%(threadName)s" to the logging format string configuration.

(Of cource, I haven't forgotten to name thread uniquely.)

Regards.

Regards.

Oops, some useless/bad codes might remain... I'm terribly sorry, please wait until the end of my re-checking.

rkmrHonjo commented 8 years ago

Dear @muroi ,

Sorry to keep you wainting. Re-checking by myself was done. Please review my codes.
