Misc #15202

Updated by jaruga (Jun Aruga) 6 months ago

Recently I reported issues detected by code analysis tool mainly using Coverity Scan.

The 9 issues categorized as "important" was fixed by #15116. (Thank you!)

However there are around 1000 "not important" issues.

Right now I do not share the report file (840KByte) for that, because it makes people tired.
If someone want to see it, I am happy that to share it here as an attachment.

Instead of that, It looks good to me that someone could see the result of coverity scan casually anytime to fix those in long term.

What I want to propose is it to add coverity scan test on rubyci or Travis CI.

I do not know how coverity scan is used on current Ruby project as a regular workflow.
But I could see it is actually used from the setting [2] and some tickets. [3]

I found how to use Coverity Scan on Travis CI [4], and the used cases [5][6].

How do you think?
