Re: [eclipse-dev] Minimal compiler severity for the Eclipse project

[Martin Aeschlimann <martin_aeschlimann@xxxxxxxxxx>]

Wouldn't it be possible that releng
uses the settings as defined per project? This would give teams freedom
and save us from surprises of non-matching settings.

Subject	[eclipse-dev] Minimal compiler severity for the Eclipse project

It appears that not all teams are tuning the compiler
settings in a similar
way, resulting sometimes in a few glitches during the build process. During
the arch call, we agreed that teams should ensure they follow the settings
used by Releng during the build process at a minimum.

Then we can discuss further on whether we want to raise the bar or not.
As
the compiler owner, I wouldn't change its defaults but rather have dev
teams agree on custom settings; since changing defaults has some
implications for tools generating source code; i.e. they could start
getting flagged with problems from now on.

To initiate the discussion, here are the extra warnings we activate in
JDT/Core (compared to defaults).

Classfile Generation
- Inline finally blocks: ON   (to match Releng setting for improved
startup
time)

CodeStyle
- Indirect access to static member
- Undocumented empty block
- Non externalized Strings

Potential programming problems
- Possible accidental bool assign
- Empty statements

Name shadowing and conflicts
- Field declaration hides another field or variable
- Local variable declaration hides another field or variable

Deprecated and restricted API
- Deprecated API
- Forbidden reference (ERROR)
- Discouraged reference

Unnecessary code
- Unnecessary cast or 'instanceof' operation

Javadoc
- Malformed Javadoc comments: Warning
       - Only consider members as visible as: Private
       - Report errors in tags: ON
       - Report non visible references: ON
       - Report deprecated references: ON


You can find below the corresponding .settings/org.eclipse.jdt.core.prefs
(you can simply paste the contents into your project settings to see the
consequences if you cause a rebuild, i.e. no need to go through the UI).
