* introduces -Yshow-symownersEugene Burmako2014-02-108-40/+58
| | | | | | This facility, along with -Yshow-syms, has proven to be very useful when debugging problems caused by corrupt owner chains when hacking on named/default argument transformation.
* deduplication in Symbol.nameStringEugene Burmako2014-02-101-2/+1
| | | | | Since now it uses idString to print out the id part of the name when -uniqid is turned on, instead of duplicating the code from idString.

| | | | | | | | | | Now when resetAllAttrs is gone, we can use a shorter name for the one and only resetLocalAttrs.
| * SI-8248 kills resetAllAttrsEugene Burmako2014-02-071-26/+27
| | | | | | | | | | Noone uses it anymore, so I'm rushing to remove it, so that it no longer can trick people into using it.

| | | | | | | | | | Again, resetLocalAttrs works just fine there - no need to destroy references to externally defined symbols.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit removes resetAllAttrs from the public reflection API. This method was previously deprecated, but on a second thought that doesn't do it justice. People should be aware that resetAllAttrs is just wrong, and if they have code that uses it, this code should be rewritten immediately without beating around the bush with deprecations. There's a source-compatible way of achieving that (resetLocalAttrs), so that shouldn't bring much trouble. Secondly, resetAllAttrs in compiler internals becomes deprecated. In subsequent commits I'm going to rewrite the only two locations in the compiler that uses it, and then I think we can remove it from the compiler as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A denshish refactor makes the FormatInterpolator a nice bundle that destructures its input and flattens out the classes to give the code some elbow room. Everything shifts left. The `checkType` method is refolded and renamed `pickAcceptable`. An additional test case captures the leading edge test, that a % should follow a hole, and which is the most basic requirement.
| * | SI-8092 More verify for f-interpolatorSom Snytt2014-01-286-157/+443
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Attempt to verify the nooks and crannies of the format string. Allows all syntax in the javadoc, including arg indexes. If the specifier after an arg has an index that doesn't refer to the arg, a warning is issued and the missing `%s` is prepended (just as for a part with a leading `%n`). Other enhancements include detecting that a `Formattable` wasn't supplied to `%#s`. Error messages attempt to be pithy but descriptive.

| * | | turns off the gilSynchronizedIfNotInited optimizationEugene Burmako2014-02-011-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | According to Jason (https://github.com/scala/scala/pull/3391#issuecomment-32904460), this one is still causing trouble, so we have to turn it off until we have time to debug it.
| * | | SI-8131 fixes residual race condition in runtime reflectionEugene Burmako2014-01-2111-118/+224
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apparently some completers can call setInfo while they’re not yet done, which resets the LOCKED flag, and makes anything that uses LOCKED to track completion unreliable. Unfortunately, that’s exactly the mechanism that was used by runtime reflection to elide locking for symbols that are known to be initialized. This commit fixes the problematic lock elision strategy by introducing an explicit communication channel between SynchronizedSymbol’s and their completers. Now instead of trying hard to infer whether it’s already initialized or not, every symbol gets a volatile field that can be queried to provide necessary information.
| * | | removes non-determinism in reflection-sync-potpourriEugene Burmako2014-01-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Depending on the environment in which the test is run, s1 can be either “String” or “java.lang.String”. This is one of the known non-deterministic behaviors of our reflection, caused by prefix stripping only working for packages defined in the root mirror. Until we fix this, I suggest we make the test more lenient.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Such representation codifies the fact that type tree that doesn't have embedded syntactic equivalent must have been inferred or otherwise provided by the compiler rather than specified by the end user. Additionally it also ensures that we can still match trees without explicit types (e.g. vals without type) after typechecking. Otherwise the same quote couldn't be used in situations like: val q"val x = 42" = typecheck(q"val x = 42")

I also considered whether to do a deep check on the type (`isErroneous`), but I can't motivate this with a test. I tend to think we *shouldn't* do that: `List[${ErrorType}]` still has an `apply` member that we should follow, right?
