Re: getting a handle on build warnings

[Jonathan Gibbons]

I've written a program to analyze the warnings in a build log, 
containing most of
the ideas I outlined earlier, and more.

Right now, a "warning" is defined as a line containing the string "warning"
with false positives filtered out (e.g. a reference to a file called 
warning.png)

It can generate a report in plain text or html, containing any/all of 
the following:
- comparison against a reference log, such as the log for an earlier 
promoted build
- a summary of the warnings, grouped by the location contained in the 
warning
- a summary of the warnings, grouped by the type of the warning
The summaries are given sorted both alphabetically and by frequency.

I've attached a sample of the output. The input was the log for a build 
on my
laptop. For the purposes of testing, the "reference" was the same log 
truncated
to 25000 lines.

The big surprise: One file is responsible for nearly 72% of all the 
warnings in this
build: 1928 warnings out of a total of 2684!  The file in question is
   com/sun/java/util/jar/pack/coding.cpp

The corollary is good news for everyone else; there are fewer warnings 
through
the rest of the build than I expected, with only 14 files having 10 or 
more warnings.
But, there are still over 150 files containing warnings :-(

Well, here's an unexpected initial result.

I just ran a build of langtools+jdk on my ubuntu laptop.   I got a 
whopping 2658 warnings!!  [Those who volunteered to help get rid of 
all the warnings, don't all step back at once!]  But surprisingly, 
after a quick "sort -u", only 625 of them are unique. So that means we 
get on average a 4x bang for the buck for each warning we fix :-)

Depending on what lint options you use, deprecation warnings are 
typically reported as a single "Note:" at the end of the compilation, 
rather than as individual warning messages.  Ideally, they should go 
too, but for now, I'd settle for removing messages that show up as 
diagnostics in IDEs, emacs, etc.

For my part, I work mostly in the langtools area,  and we are having 
a general background effort to clean up the code there. The goal is 
to clean the code and then use -Werror to treat any reappearance of 
warnings as errors.

Just curious, would part of this revision process entail removing 
calls to deprecated methods and replacing them with their documented 
replacement methods?

There are many warnings about calls to deprecated methods in the 
OpenJDK code.

Yes, that technique can work well. But either way, the next step is
to try writing the code to analyze the build log, to see how far 
the general
idea can be taken, and how much interest there is to track/fix 
warnings.

Personally I'd like there to be no warnings at all, and would like 
to contribute work to get there


Thank you.

Getting rid of the actual warnings will require cooperation from 
the teams who are
responsible for the various parts of the code. In some cases, there 
may be resistance,
since stability is sometimes preferred over "no warnings".  That 
being said, what I'm
hoping to achieve with this discussion and any related effort is a 
non-intrusive way
of gathering information about warnings, so that we have a better 
understanding of
where the warnings are, in what areas of the code and in which 
source files.  That way,
we can work with the teams involved to see if there is interest in 
reducing their
warning count in as safe a way as possible.  Any assistance in 
getting to that point
would be welcome.
