Changing deprecation warning to lineStream
|
| | | |
| | |
| | |
| | |
| | |
| | | |
The deprecation text of `ProcessBuilder.lines(log: ProcessLogger)` and `ProcessBuilder.lines_!(log: ProcessLogger) mentions to use the method `stream` and `stream_!` respectively. These methods do not exists.
The text has been changed to use `lineStream` and `lineStream_!` respectively.

SI-10177 Override lazy operations to preserve TrieMap's semantics

Calling .iterator on a TrieMap gives a read-only snapshot. This then
extends to most inherited implementations written in terms of .iterator.
However, some inherited methods, such as .values, either defer the call
to .iterator or call it more than once. This results in subsequent
mutations to the original map being visible
I reviewed the inherited implementations from MapLike and found we
needed overrides of `values`, `keySet`, `filterKeys`, and `mapValues`.
Like `iterator`, these now create a read-only snapshot.

SI-10072 cast Function nodes to environment in specialization

This commit basically make sure the fix for SI-5284 works correctly when
a Function node reaches specialization (`-Ydealmbdafy:method` and
IndyLambda are default in 2.12.x). To understand it, best read the
excellent description in b29c01b.
The code that's removed in this commit was added in 13ea590. It
prevented `castType` from being invoked on the `Function` node, which
is exactly what is needed here. It's also what happens under
`-Ydelambdafy:inline`, the `new anonfun()` tree is being casted from
`(Int, Int) => Int` to `(Int, A) => Int`.

The compiler support in the typechecker for `scala.Dynamic` is
very particular about the `Context` in which it is typechecked.
It looks at the `tree` in the enclosing context to find the expression
immediately enclosing the dynamic selection. See the logic in
`dyna::mkInvoke` for the details.
This commit substitutes the result of `resetAttrs` into the tree
of the typer context before continuing with typechecking.

I see no further reason to include them in the bootstrap process.
Adriaan agrees (in-person discussion).
note that the community build makes sure the modules still compile as
we make changes to Scala.
as for actually publishing scala-parser-combinators and scala-swing
when we make binary incompatible changes to Scala, I think it's fine
to consider that properly the job of the module maintainers, rather
than properly the job of this script. (if we want more automation
on that, we could make some elsewhere, keeping that concern separate
from actual bootstrapping concerns.)
scala-xml, scala-partest, and scalacheck (commented out at the moment)
remain in this script since they are all actually still part of the
bootstrapping picture.
fixes https://github.com/scala/scala-dev/issues/302 , so that
integrate-bootstrap will pass again (currently it fails, since
scala-parser-combinators merged Scala.js support)

A Scala method that implements a generic, Java-defined
varargs method, needs two bridges:
- to convert the collections for the repeated parameters (VBRIDGE)
- to bridge the generics gap (BRIDGE)
Refchecks emits the varargs "bridges", and erasure takes care
of the other gap. Because a VBRIDGE was also an ARTIFACT,
it was wrongly considered inert with respect to erasure,
because `OverridingPairs` by default excluded artifacts.
Removed the artifact flag from those VBRIDGES, so that they
qualify for a real bridge. It would also work to include
VBRIDGE methods that are artifacts in BridgesCursor.

`s.c.i.RedBlackTree.TreeIterator` uses a stack of nodes that need
to be processed later. This stack is implemented as an `Array`,
which is allocated with the maximum size that can possibly be
used, based on properties of red-black trees. This was added in
72ec0ac869a29fca9ea0d45a3f70f1e9e1babaaf. At the time, there was
no `iteratorFrom` method, and as the comment in that commit says,
the deepest nodes were never added to the stack, hence the final
`- 1` in computing the maximum stack size.
However, this changed with the introduction of `iteratorFrom` in
62bc99d3b20a7b37a977b19a6202cdac474eb5f6. The method `startFrom`
used to initialize the iterator at the right `start` node does
push the deepest nodes in some cases.
This internal bug got unnoticed because `pushNext` (originally
`pushPath`) has some error recovery in case the stack size got
miscalculated. This has performance impacts, though, since an
exception is thrown and caught.
More importantly, this error recovery mechanism does not work in
Scala.js, which considers `ArrayIndexOutOfBoundsException` to be
undefined behavior.
This commit fixes the stack size computation by simply removing
the `- 1` term. To minimize risks on Scala/JVM, the error recovery
mechanism is left untouched.

Make sure that methods annotated with varargs are properly mixed-in. This commit
splits the transformation into an info transformer (that works on all symbols, whether
they come from source or binary) and a tree transformer.
The gist of this is that the symbol-creation part of the code was moved to the UnCurry
info transformer, while tree operations remained in the tree transformer. The newly
created symbol is attached to the original method so that the tree transformer can still
retrieve the symbol.
A few fall outs:
- I removed a local map that was identical to TypeParamsVarargsAttachment
- moved the said attachment to StdAttachments so it’s visible between reflect.internal
and nsc.transform
- a couple more comments in UnCurry to honour the boy-scout rule

When generating a varargs forwarder for
def foo[T](a: T*)
the parameter type of the forwarder needs to be Array[Object]. If we
generate Array[T] in UnCurry, that would be erased to plain Object, and
the method would not be a valid varargs.
Unfortunately, setting the parameter type to Array[Object] lead to
an invalid generic signature - the generic signature should reflect the
real signature.
This change adds an attachment to the parameter symbol in the varargs
forwarder method and special-cases signature generation.
Also cleans up the code to produce the varargs forwarder. For example,
type parameter and parameter symbols in the forwarder's method type were
not clones, but the same symbols from the original method were re-used.
Backported from 0d2760dce189cdcb363e54868381175af4b2646f,
with a small tweak (checkVarargs) to make the test work on Java 6,
as well as later versions.

When determining whether or not a pattern match requires an equality
check of the outer instance of a type in addition to a type test,
`needsOuterTest` determines if the intersection of the selector and
the pattern types could be populated. Both type arrive at
`isPopulated` dealised.
However, `isPopulated` recurs when it encounters an existential,
and, as seen in thest case, a failure to dealias the quantified
type can lead to an assertion failure as we try to relate a
typeref to an alias and a typeref to a class.
See also SI-7214, which added deliasing of the pattern type
before calling `isPopulated`.

Here's the changelog since JLine 2.12.1:
https://github.com/jline/jline2/compare/jline-2.12.1...jline-2.14.3
I needed to disable a new, on-by-default feature in JLine so that
it didn't add a " " after completing the token `equals` in
`foo.equa<TAB>`.
