Confusing, now-it-happens now-it-doesn't mysteries lurk
in the darkness. When scala packages are declared like this:
package scala.collection.mutable
Then paths relative to scala can easily be broken via the unlucky
presence of an empty (or nonempty) directory. Example:
// a.scala
package scala.foo
class Bar { new util.Random }
% scalac ./a.scala
% mkdir util
% scalac ./a.scala
./a.scala:4: error: type Random is not a member of package util
new util.Random
^
one error found
There are two ways to play defense against this:
- don't use relative paths; okay sometimes, less so others
- don't "opt out" of the scala package
This commit mostly pursues the latter, with occasional doses
of the former.
I created a scratch directory containing these empty directories:
actors annotation ant api asm beans cmd collection compat
concurrent control convert docutil dtd duration event factory
forkjoin generic hashing immutable impl include internal io
logging macros man1 matching math meta model mutable nsc parallel
parsing partest persistent process pull ref reflect reify remote
runtime scalap scheduler script swing sys text threadpool tools
transform unchecked util xml
I stopped when I could compile the main src directories
even with all those empties on my classpath.

Some names I missed in 55b609458fd .
How one might know when one is done:
mkdir scratch && cd scratch
mkdir annotation beans collection compat concurrent io \
math parallel ref reflect runtime scala sys testing \
text tools util xml
scalac $(find ../src/library -name '*.scala')
Until recently that would fail with about a billion errors. When it
compiles, that's when you're done. And that's where this commit
takes us, for src/library at least.

I wrote a warning when nullary methods return Unit. I wimped out of
including it in this patch because we had about 200 of them, and that's
what is fixed in this patch. I will add the warning to some kind of
"-Xlint" feature after 2.9.
This is motivated at least partly by the resolution of #4506, which
indicates the distinction between "def foo()" and "def foo" will
continue to jab its pointy stick into our eyes, so I believe we have a
minimal duty of at least following our own advice about what they mean
and not making a semirandom choice as to whether a method has parens or
not. Review by community.

Some much needed housecleaning regarding system properties. If you can
possibly resist the temptation, it'd be great if people could try to
go through the properties classes to get and set them, and also to set
property values somewhere fixed rather than using strings directly.

The standard library will now be laid out approximately like this
library/scala
/jvm/scala
/jvm/jvm1.4/scala
/jvm/jvm1.5/scala
/jvm/android/scala
/jvm/cldc/scala
/dotnet/scala
To build the standard library for a given target you start by copying
the root library/scala tree to a staging area, then move down in the
hierarchy copying the nested "scala" trees on top in the staging area.
So if you wanted to build for cldc, for example, you would do something
like the following:
rsync -avz library/scala staging/
rsync -avz library/scala/jvm/scala staging/
rsync -avz library/scala/jvm/cldc/scala staging/
The ant build files will be updated to do this for you automagically,
and there will soon be shell script to do this if you want to compile
some parts of the standard library manually.
