From 80ac7d006350c0d60ff1b293ee955c3435288a9e Mon Sep 17 00:00:00 2001 From: Paul Phillips Date: Fri, 3 May 2013 10:15:10 -0700 Subject: Absolutized paths involving the scala package. 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. --- src/library/scala/collection/mutable/DefaultMapModel.scala | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/library/scala/collection/mutable/DefaultMapModel.scala') diff --git a/src/library/scala/collection/mutable/DefaultMapModel.scala b/src/library/scala/collection/mutable/DefaultMapModel.scala index 903f117466..4dfae047c3 100644 --- a/src/library/scala/collection/mutable/DefaultMapModel.scala +++ b/src/library/scala/collection/mutable/DefaultMapModel.scala @@ -8,7 +8,8 @@ -package scala.collection +package scala +package collection package mutable /** This class is used internally.
