Changelog extracted from https://nim-lang.org/blog/2020/10/16/version-140-released.html
Standard library additions and changes
Added some enhancements to std/jsonutils module.
Added a possibility to deserialize JSON arrays directly to
HashSet and OrderedSet types and respectively to serialize
those types to JSON arrays via jsonutils.fromJson and
jsonutils.toJson procedures.
Added a possibility to deserialize JSON null objects to Nim
option objects and respectively to serialize Nim option object
to JSON object if isSome or to JSON null object if isNone via
jsonutils.fromJson and jsonutils.toJson procedures.
Added a Joptions parameter to jsonutils.fromJson currently
containing two boolean options allowExtraKeys and
allowMissingKeys.
If allowExtraKeys is true Nim’s object to which the JSON
is parsed is not required to have a field for every JSON
key.
If allowMissingKeys is true Nim’s object to which JSON is
parsed is allowed to have fields without corresponding
JSON keys.
Added bindParams, bindParam to db_sqlite for binding parameters
into a SqlPrepared statement.
Added tryInsert,insert procs to db_* libs which accept primary key
column name.
Added xmltree.newVerbatimText support create style’s,script’s
text.
uri module now implements RFC-2397.
Added DOM Parser to the dom module for the JavaScript target.
The default hash for Ordinal has changed to something more
bit-scrambling. import hashes; proc hash(x: myInt): Hash =
hashIdentity(x) recovers the old one in an instantiation context
while -d:nimIntHash1 recovers it globally.
deques.peekFirst and deques.peekLast now have var Deque[T] -> var T
overloads.
File handles created from high-level abstractions in the stdlib
will no longer be inherited by child processes. In particular,
these modules are affected: asyncdispatch, asyncnet, system,
nativesockets, net and selectors.
For asyncdispatch, asyncnet, net and nativesockets, an inheritable
flag has been added to all procs that create sockets, allowing the
user to control whether the resulting socket is inheritable. This
flag is provided to ease the writing of multi-process servers,
where sockets inheritance is desired.
For a transition period, define nimInheritHandles to enable file
handle inheritance by default. This flag does not affect the
selectors module due to the differing semantics between operating
systems.
asyncdispatch.setInheritable, system.setInheritable and nativesockets.setInheritable are also introduced for setting file handle or socket inheritance. Not all platforms have these procs defined.
The file descriptors created for internal bookkeeping by
ioselector_kqueue and ioselector_epoll will no longer be leaked to
child processes.
strutils.formatFloat with precision = 0 has been restored to the
version 1 behaviour that produces a trailing dot,
e.g. formatFloat(3.14159, precision = 0) is now 3., not 3.
Added commonPrefixLen to critbits.
relativePath(rel, abs) and relativePath(abs, rel) used to silently
give wrong results (see #13222); instead they now use
getCurrentDir to resolve those cases, and this can now throw in
edge cases where getCurrentDir throws. relativePath also now works
for js with -d:nodejs.
JavaScript and NimScript standard library changes:
streams.StringStream is now supported in JavaScript, with the
limitation that any buffer pointers used must be castable to ptr
string, any incompatible pointer type will not work. The lexbase
and streams modules used to fail to compile on NimScript due to a
bug, but this has been fixed.
The following modules now compile on both JS and NimScript:
parsecsv, parsecfg, parsesql, xmlparser, htmlparser and
ropes. Additionally supported for JS is cstrutils.startsWith and
cstrutils.endsWith, for NimScript: json, parsejson, strtabs and
unidecode.
Added streams.readStr and streams.peekStr overloads to accept an
existing string to modify, which avoids memory allocations,
similar to streams.readLine (#13857).
Added high-level asyncnet.sendTo and asyncnet.recvFrom UDP functionality.
dollars.$ now works for unsigned ints with nim js.
Improvements to the bitops module, including bitslices,
non-mutating versions of the original masking functions,
mask/masked, and varargs support for bitand, bitor, and bitxor.
sugar.=> and sugar.-> changes: Previously (x, y: int) was
transformed into (x: auto, y: int), it now becomes (x: int, y:
int) for consistency with regular proc definitions (although you
cannot use semicolons).
Pragmas and using a name are now allowed on the lefthand side of =>.
Here is an example of these changes:
import sugar
foo(x, y: int) {.noSideEffect.} => x + y
# is transformed into
proc foo(x: int, y: int): auto {.noSideEffect.} = x + y
The fields of times.DateTime are now private, and are accessed
with getters and deprecated setters.
The times module now handles the default value for DateTime more
consistently. Most procs raise an assertion error when given an
uninitialized DateTime, the exceptions are == and $ (which returns
"Uninitialized DateTime"). The proc times.isInitialized has been
added which can be used to check if a DateTime has been
initialized.
Fix a bug where calling close on io streams in osproc.startProcess was a noop and led to hangs if a process had both reads from stdin and writes (e.g. to stdout).
The callback that is passed to system.onThreadDestruction must now be .raises: [].
The callback that is assigned to system.onUnhandledException must now be .gcsafe.
osproc.execCmdEx now takes an optional input for stdin, workingDir and env parameters.
Added a ssl_config module containing lists of secure ciphers as recommended by Mozilla OpSec
net.newContext now defaults to the list of ciphers targeting “Intermediate compatibility” per Mozilla’s recommendation instead of ALL. This change should protect users from the use of weak and insecure ciphers while still provides adequate compatibility with the majority of the Internet.
A new module std/jsonutils with hookable jsonTo,toJson,fromJson operations for json serialization/deserialization of custom types was added.
A new proc heapqueue.find[T](heap: HeapQueue[T], x: T): int to get index of element x was added.
Added rstgen.rstToLatex a convenience proc for renderRstToOut and initRstGenerator.
Added os.normalizeExe.
macros.newLit now preserves named vs unnamed tuples.
Added random.gauss, that uses the ratio of uniforms method of sampling from a Gaussian distribution.
Added typetraits.elementType to get the element type of an iterable.
typetraits.$ changes: $(int,) is now "(int,)" instead of "(int)"; $tuple[] is now "tuple[]" instead of "tuple"; $((int, float), int) is now "((int, float), int)" instead of "(tuple of (int, float), int)"
Added macros.extractDocCommentsAndRunnables helper.
strformat.fmt and strformat.& support specifier =. fmt"{expr=}" now expands to fmt"expr={expr}".
Deprecations: instead of os.existsDir use dirExists, instead of os.existsFile use fileExists.
Added the jsre module, Regular Expressions for the JavaScript target..
Made maxLines argument Positive in logging.newRollingFileLogger, because negative values will result in a new file being created for each logged line which doesn’t make sense.
Changed log in logging to use proper log level for JavaScript, e.g. debug uses console.debug, info uses console.info, warn uses console.warn, etc.
Tables, HashSets, SharedTables and deques don’t require anymore that the passed initial size must be a power of two - this is done internally. Proc rightSize for Tables and HashSets is deprecated, as it is not needed anymore. CountTable.inc takes val: int again not val: Positive; i.e. it can “count down” again.
Removed deprecated symbols from macros module, some of which were deprecated already in 0.15.
Removed sugar.distinctBase, deprecated since 0.19. Use typetraits.distinctBase.
asyncdispatch.PDispatcher.handles is exported so that an external low-level libraries can access it.
std/with, sugar.dup now support object field assignment expressions:
import std/with
type Foo = object
x, y: int
var foo = Foo()
with foo:
x = 10
y = 20
echo foo
Proc math.round is no longer deprecated. The advice to use strformat instead cannot be applied to every use case. The limitations and the (lack of) reliability of round are well documented.
Added getprotobyname to winlean. Added getProtoByname to nativesockets which returns a protocol code from the database that matches the protocol name.
Added missing attributes and methods to dom.Navigator like deviceMemory, onLine, vibrate(), etc.
Added strutils.indentation and strutils.dedent which enable indented string literals:
import strutils
echo dedent """
This
is
cool!
"""
Added initUri(isIpv6: bool) to uri module, now uri supports parsing ipv6 hostname.
Added readLines(p: Process) to osproc.
Added the below toX procs for collections. The usage is similar to procs such as sets.toHashSet and tables.toTable. Previously, it was necessary to create the respective empty collection and add items manually.
critbits.toCritBitTree, which creates a CritBitTree from an openArray of items or an openArray of pairs.
deques.toDeque, which creates a Deque from an openArray.
heapqueue.toHeapQueue, which creates a HeapQueue from an openArray.
intsets.toIntSet, which creates an IntSet from an openArray.
Added progressInterval argument to asyncftpclient.newAsyncFtpClient to control the interval at which progress callbacks are called.
Added os.copyFileToDir.
Language changes
The =destroy hook no longer has to reset its target, as the compiler now automatically inserts wasMoved calls where needed.
The = hook is now called =copy for clarity. The old name = is still available so there is no need to update your code. This change was backported to 1.2 too so you can use the more readable =copy without loss of compatibility.
In the newruntime it is now allowed to assign to the discriminator field without restrictions as long as the case object doesn’t have a custom destructor. The discriminator value doesn’t have to be a constant either. If you have a custom destructor for a case object and you do want to freely assign discriminator fields, it is recommended to refactor the object into 2 objects like this:
type
MyObj = object
case kind: bool
of true: y: ptr UncheckedArray[float]
of false: z: seq[int]
proc `=destroy`(x: MyObj) =
if x.kind and x.y != nil:
deallocShared(x.y)
Refactor into:
type
MySubObj = object
val: ptr UncheckedArray[float]
MyObj = object
case kind: bool
of true: y: MySubObj
of false: z: seq[int]
proc `=destroy`(x: MySubObj) =
if x.val != nil:
deallocShared(x.val)
getImpl on enum type symbols now returns field syms instead of idents. This helps with writing typed macros. The old behavior for backwards compatibility can be restored with --useVersion:1.0.
The typed AST for proc headers will now have the arguments be syms instead of idents. This helps with writing typed macros. The old behaviour for backwards compatibility can be restored with --useVersion:1.0.
let statements can now be used without a value if declared with importc/importcpp/importjs/importobjc.
The keyword from is now usable as an operator.
Exceptions inheriting from system.Defect are no longer tracked with the .raises: [] exception tracking mechanism. This is more consistent with the built-in operations. The following always used to compile (and still does):
proc mydiv(a, b): int {.raises: [].} =
a div b # can raise an DivByZeroDefect
Now also this compiles:
proc mydiv(a, b): int {.raises: [].} =
if b == 0: raise newException(DivByZeroDefect, "division by zero")
else: result = a div b
The reason for this is that DivByZeroDefect inherits from Defect and with --panics:on Defects become unrecoverable errors.
Added the thiscall calling convention as specified by Microsoft, mostly for hooking purposes.
Deprecated the {.unroll.} pragma, because it was always ignored by the compiler anyway.
Removed the deprecated strutils.isNilOrWhitespace.
Removed the deprecated sharedtables.initSharedTable.
Removed the deprecated asyncdispatch.newAsyncNativeSocket.
Removed the deprecated dom.releaseEvents and dom.captureEvents.
Removed sharedlists.initSharedList, was deprecated and produces undefined behaviour.
There is a new experimental feature called “strictFuncs” which makes the definition of .noSideEffect stricter. See here for more information.
“for-loop macros” (see the manual) are no longer an experimental feature. In other words, you don’t have to write pragma {.experimental: "forLoopMacros".} if you want to use them.
Added the .noalias pragma. It is mapped to C’s restrict keyword for the increased performance this keyword can enable.
items no longer compiles with enums with holes as its behavior was error prone, see #14004.
system.deepcopy has to be enabled explicitly for --gc:arc and --gc:orc via --deepcopy:on.
Added the std/effecttraits module for introspection of the inferred effects. We hope this enables async macros that are precise about the possible exceptions that can be raised.
The pragma blocks {.gcsafe.}: ... and {.noSideEffect.}: ... can now also be written as {.cast(gcsafe).}: ... and {.cast(noSideEffect).}: .... This is the new preferred way of writing these, emphasizing their unsafe nature.
Compiler changes
Specific warnings can now be turned into errors via --warningAsError[X]:on|off.
The define and undef pragmas have been de-deprecated.
New command: nim r main.nim [args...] which compiles and runs main.nim, and implies --usenimcache so that the output is saved to $nimcache/main$exeExt, using the same logic as nim c -r to avoid recompilations when sources don’t change. Example:
nim r compiler/nim.nim --help # only compiled the first time
echo 'import os; echo getCurrentCompilerExe()' | nim r - # this works too
nim r compiler/nim.nim --fullhelp # no recompilation
nim r --nimcache:/tmp main # binary saved to /tmp/main
--hint:processing is now supported and means --hint:processing:on (likewise with other hints and warnings), which is consistent with all other bool flags. (since 1.3.3).
nim doc -r main and nim rst2html -r main now call openDefaultBrowser.
Added the new hint --hint:msgOrigin will show where a compiler msg (hint|warning|error) was generated; this helps in particular when it’s non obvious where it came from either because multiple locations generate the same message, or because the message involves runtime formatting.
Added the new flag --backend:js|c|cpp|objc (or -b:js etc), to change the backend; can be used with any command (e.g. nim r, doc, check etc); safe to re-assign.
Added the new flag --doccmd:cmd to pass additional flags for runnableExamples, e.g.: --doccmd:-d:foo --threads use --doccmd:skip to skip runnableExamples and rst test snippets.
Added the new flag --usenimcache to output binary files to nimcache.
runnableExamples "-b:cpp -r:off": code is now supported, allowing to override how an example is compiled and run, for example to change the backend.
nim doc now outputs under $projectPath/htmldocs when --outdir is unspecified (with or without --project); passing --project now automatically generates an index and enables search. See docgen for details.
Removed the --oldNewlines switch.
Removed the --laxStrings switch for mutating the internal zero terminator on strings.
Removed the --oldast switch.
Removed the --oldgensym switch.
$getType(untyped) is now “untyped” instead of “expr”, $getType(typed) is now “typed” instead of “stmt”.
Sink inference is now disabled per default and has to enabled explicitly via --sinkInference:on. Note: For the standard library sink inference remains enabled. This change is most relevant for the --gc:arc, --gc:orc memory management modes.
Tool changes
nimsuggest now returns both the forward declaration and the implementation location upon a def query. Previously the behavior was to return the forward declaration only.

It seems to be a generally useful feature. If a package supports
optional cargo dependencies then you may now (instead of messing with
CARGO_ARGS directly) set in your Makefile for example:
CARGO_NO_DEFAULT_FEATURES= YES
CARGO_FEATURES+= dbus pulseaudio
"Over the last releases, the Elixir team has been focusing on the compiler, both in terms of catching more mistakes at compilation time and making it faster. Elixir v1.11 has made excellent progress on both fronts. This release also includes many other goodies, such as tighter Erlang integration, support for more guard expressions, built-in datetime formatting, and other calendar enhancements."

Install the new interchangeable BLAS system created by Thomas Orgis,
currently supporting Netlib BLAS/LAPACK, OpenBLAS, cblas, lapacke, and
Apple's Accelerate.framework. This system allows the user to select any
BLAS implementation without modifying packages or using package options, by
setting PKGSRC_BLAS_TYPES in mk.conf. See mk/blas.buildlink3.mk for details.
This commit should not alter behavior of existing packages as the system
defaults to Netlib BLAS/LAPACK, which until now has been the only supported
implementation.
Details:
Add new mk/blas.buildlink3.mk for inclusion in dependent packages
Install compatible Netlib math/blas and math/lapack packages
Update math/blas and math/lapack MAINTAINER approved by adam@
OpenBLAS, cblas, and lapacke will follow in separate commits
Update direct dependents to use mk/blas.buildlink3.mk

Ruby 2.7.2 Released
Posted by nagachika on 2 Oct 2020
Ruby 2.7.2 has been released.
This release contains intentional incompatibility. The deprecated warnings
are off by default on 2.7.2 and later. You can turn on the deprecated
warnings by specifing command line option -w or -W:deprecated. Please check
the topics below for details.
* Feature #17000 2.7.2 turns off deprecation warnings by default
* Feature #16345 Don¡Çt emit deprecation warnings by default.
This release contains the new version of webrick with a security fix
described in the article.
* CVE-2020-25613: Potential HTTP Request Smuggling Vulnerability in WEBrick
## 1.12.2 - 2020-09-20
- Add janet\_try and janet\_restore to C API.
- Fix `os/execute` regression on windows.
- Add :pipe option to `os/spawn`.
- Fix docstring typos.
## 1.12.1 - 2020-09-07
- Make `zero?`, `one?`, `pos?`, and `neg?` polymorphic.
- Add C++ support to jpm and improve C++ interop in janet.h.
- Add `%t` formatter to `printf`, `string/format`, and other formatter functions.
- Expose `janet_cfuns_prefix` in C API.
- Add `os/proc-wait` and `os/proc-kill` for interacting with processes.
- Add `janet_getjfile` to C API.
- Allow redirection of stdin, stdout, and stderr by passing keywords in the env table in `os/spawn` and `os/execute`.
- Add `os/spawn` to get a core/process back instead of an exit code as in `os/execute`.
When called like this, `os/execute` returns immediately.
- Add `:x` flag to os/execute to raise error when exit code is non-zero.
- Don't run `main` when flychecking.
- Add `:n` flag to `file/open` to raise an error if file cannot be opened.
- Fix import macro to not try and coerce everything to a string.
- Allow passing a second argument to `disasm`.
- Add `cancel`. Resumes a fiber but makes it immediately error at the yield point.
- Allow multi-line paste into built in repl.
- Add `(curenv)`.
- Change `net/read`, `net/chunk`, and `net/write` to raise errors in the case of failures.
- Add `janet_continue_signal` to C API. This indirectly enables C functions that yield to the event loop
to raise errors or other signals.
- Update meson build script to fix bug on Debian's version of meson
- Add `xprint`, `xprin`, `xprintf`, and `xprinf`.
- `net/write` now raises an error message if write fails.
- Fix issue with SIGPIPE on macOS and BSDs.
One of the two patches fixing the build on NetBSD was wrong; I had modified it
to build again but it turns out it was not necessary at all in the first place.
I just confirmed it on netbsd-9/amd64.
Bumps PKGREVISION for safety, since it built again after modifying the original
patch.

On NetBSD, further limit the DEPENDS on openssl to i386. It turns out
that the sparc64 and powerpc bootstraps are not linked against openssl
as I previously assumed.
No change to limiting this DEPENDS to 9+. No change to any other OS.
This change is believed to fix rust building on NetBSD 9 sparc64.
As discussed on tech-pkg@.

For background, the bootstrap kits need pkgsrc openssl present to run.
Then, the built cargo links against libs from pkgsrc openssl. One
would expect USE_BUILTIN.openssl=no to cause the later bl3 to depend
on pkgsrc openssl, and it does, but then there is a mysterious error
about not being able to buildlink heimdal.
This commit, relative to how 1.192, modifies comments and adds a
straight DEPENDS:
DEPENDS+= openssl>=1.1:../../security/openssl
only in the case of NetBSD, >=9, i386/sparc64/powerpc.
More or less as proposed on tech-pkg, with no responses.
On NetBSD i386 (and sparc64 and powerpc), we have bootstrap kits that
are linked against pkgsrc openssl. Previously rust BUILD_DEPENDed on
openssl so they could run but this resulted in an installed cargo that
linked against that openssl. This changes the depend method to
straight bl3, so openssl will be a runtime dependency.
This continues to be icky, but after a long period of discussion on
the lists, no other this-branch fixes to make NetBSD 9/i386 be able to
build rust have been suggested, and further there no objections.
It is expected that the bootstrap process will be rototilled after
2020Q3 is cut; this situation is obviously not a good one to continue.
On NetBSD >8, for several CPU types we depend on compat80, because
bootstrap kits are build for NetBSD 8. On those, also add a
BUILD_DEPENDS on openssl, because the bootstrap kits need pkgsrc
openssl libs.
Adjust and reorganize comments (but the only functional change is the
NetBSD >8 openssl BUILD_DEPENDS).>
Resolves failure to build on NetBSD 9.
(The entire "NetBSD>8" section is a hack that can be removed with
improved bootstrap generation.)
Backport 3 vulnerability fixes from Python 3.6 using rebased patches
from Gentoo. These are:
bpo-39017 (CVE-2019-20907): infinite loop in tarfile.py
bpo-39503 (CVE-2020-8492): ReDoS on AbstractBasicAuthHandler
bpo-39603 (no CVE): header injection via HTTP method
required to gain access to 8-byte atomics. Add a hacks.mk file
to pull in devel/libatomic on powerpc ports. The reason is that
even though llvm itself doesn't need or use 8-byte atomics, other
programs refer to this installed CheckAtomic cmake file and may
indeed both need and use 8-byte atomics.
Verified that llvm still builds on NetBSD/macppc 9.0.
Bump PKGREVISION to 1.

JDK 15 Release Notes
These notes describe important changes, enhancements, removed APIs and
features, deprecated APIs and features, and other information about JDK 15 and
Java SE 15. In some cases, the descriptions provide links to additional
detailed information about an issue or a change. This page does not duplicate
the descriptions provided by the Java SE 15 ( JSR 390) Platform Specification,
which provides informative background for all specification changes and might
also include the identification of removed or deprecated APIs and features not
described here. The Java SE 15 ( JSR 390) specification provides links to:
* Annex 1: The complete Java SE 15 API Specification.
* Annex 2: An annotated API specification showing the exact differences
relative to Java SE 15. Informative background for these changes may be
found in the list of approved Change Specification Requests for this
release.
* Annex 3: Java SE 15 Editions of The Java Language Specification and The
Java Virtual Machine Specification. . The Java SE 15 Editions contain all
corrections and clarifications made since the Java SE 14 Editions, as well
as additions for new features.
You should be aware of the content in that document as well as the items
described in this page.
The descriptions on this Release Note page also identify potential
compatibility issues that you might encounter when migrating to JDK 15. The
Kinds of Compatibility page on the OpenJDK wiki identifies three types of
potential compatibility issues for Java programs used in these descriptions:
* Source: Source compatibility preserves the ability to compile existing
source code without error.
* Binary: Binary compatibility is defined in The Java Language Specification
as preserving the ability to link existing class files without error.
* Behavioral: Behavioral compatibility includes the semantics of the code
that is executed at runtime.
See CSRs Approved for JDK 15 for the list of CSRs closed in JDK 15 and the
Compatibility & Specification Review (CSR) page on the OpenJDK wiki for general
information about compatibility.

New Features
This section describes some of the enhancements in Java SE 15 and JDK 15. In
some cases, the descriptions provide links to additional detailed information
about an issue or a change. The APIs described here are those that are provided
with the Oracle JDK. It includes a complete implementation of the Java SE 15
Platform and additional Java APIs to support developing, debugging, and
monitoring Java applications. Another source of information about important
enhancements and new features in Java SE 15 and JDK 15 is the Java SE 15 ( JSR
390) Platform Specification, which documents the changes to the specification
made between Java SE 14 and Java SE 15. This document includes descriptions of
those new features and enhancements that are also changes to the specification.
The descriptions also identify potential compatibility issues that you might
encounter when migrating to JDK 15.
Support for Unicode 13.0 (JDK-8239383)
core-libs/java.lang
This release upgrades Unicode support to 13.0, which includes the following:
* The java.lang.Character class supports Unicode Character Database of 13.0
level, which 13.0 adds 5,930 characters, for a total of 143,859 characters.
These additions include 4 new scripts, for a total of 154 scripts, as well
as 55 new emoji characters.
* The java.text.Bidi and java.text.Normalizer classes support 13.0 level of
Unicode Standard Annexes, #9 and #15, respectively.
* The java.util.regex package supports Extended Grapheme Clusters based on
13.0 level of Unicode Standard Annex #29 For more detail about Unicode
13.0, refer to the Unicode Consortium's release note.
Added isEmpty Default Method to CharSequence (JDK-8215401)
core-libs/java.lang
java.lang.CharSequence has been updated in this release to define a default
isEmpty method that tests if a character sequence is empty. Testing for, and
filtering out, empty Strings and other CharSequences is a common occurrence in
code and CharSequence::isEmpty can be used as a method reference. Classes that
implement java.lang.CharSequence and another interface that defines isEmpty
method should be aware of this addition as they may need to be modified to
override the isEmpty method.
JEP 371: Hidden Classes (JDK-8238358)
core-libs/java.lang.invoke
JEP 371 introduces hidden classes in Java 15. Hidden classes have the following
implications to existing code:
1. Class::getName traditionally returns a binary name, but for a hidden class
it returns a string that contains an ASCII forward slash (/) and is
therefore not a binary name. Programs that assume the returned string is a
binary name might need to be updated to handle hidden classes. That said,
the longstanding practice of Unsafe::defineAnonymousClass was to define
classes whose names were not binary names, so some programs may already
handle such names successfully.
2. Class::descriptorString and MethodType::descriptorString returns a string
that contains a ASCII dot (.) for a hidden class and therefore is not a
type descriptor conforming to JVMS 4.3. Programs that assume the returned
string is a type descriptor that conforms to JVMS 4.3 might need to be
updated to handle hidden classes.
3. Class::getNestMembers is changed to not throw an exception when it fails to
validate a nest membership of any member listed in NestMembers attribute.
Instead, Class::getNestMembers returns the nest host and the members listed
in the host's NestMembers attribute that are successfully resolved and
determined to have the same nest host as this class. (This means it may
return fewer members that listed in NestMembers attribute.) Existing code
that expects LinkageError when there is a bad nest membership might be
impacted.
4. The nestmate test in the JVM is changed to throw only IllegalAccessError
when the nest membership is invalid. Some historical understanding is
necessary:
* In Java 8, every access control failure was signaled with
IllegalAccessError (IAE). Moreover, if a given access check failed with IAE
once, then the same check would fail with IAE every time.
* In Java 11, the introduction of nest mates (JEP 181) meant that an access
control failure could be signaled either with IllegalAccessError or, if
nest membership was invalid, LinkageError. Still, if a given access check
failed with a specific exception, then the same check would always fail
with the same exception.
* In Java 15, the introduction of Lookup::defineHiddenClass implies that the
nest host of the lookup class must be determined eagerly, when the hidden
class is defined as a nestmate of the lookup class. Both
Lookup::defineHiddenClass and Class::getNestHost both determine the nest
host of a class in a more resilient manner than the JVM did in Java 11;
namely, the API simply treats a class as self-hosted if its purported nest
membership is invalid. For consistency with the API, the JVM no longer
throws LinkageError when a class's nest membership is invalid, and instead
treats the class as self-hosted. This means that the JVM only throws IAE
from access control (because a self-hosted class will not permit any other
class to access its private members). This is the behavior expected by the
vast majority of user code.
5. JVM TI GetClassSignature returns a string that contains a ASCII dot (.) for
a hidden class. JVM TI agents might need updating for hidden classes if
they assume the returned string from GetClassSignature is a type descriptor
conforming to JVMS 4.3.
Added Support for SO_INCOMING_NAPI_ID Support (JDK-8243099)
core-libs/java.net
A new JDK-specific socket option SO_INCOMING_NAPI_ID has been added to
jdk.net.ExtendedSocketOptions in this release. The socket option is Linux
specific and allows applications to query the NAPI (New API) ID of the
underlying device queue associated with its socket connection and take
advantage of the Application Device Queue (ADQ) feature of high performance
Network Interface Card (NIC) devices.
Specialized Implementations of TreeMap Methods (JDK-8176894)
core-libs/java.util:collections
The TreeMap class now provides overriding implementations of the putIfAbsent,
computeIfAbsent, computeIfPresent, compute, and merge methods. The new
implementations provide a performance improvement. However, if the function
provided to the compute- or merge methods modifies the map,
ConcurrentModificationException may be thrown, because the function that is
provided to these methods is prohibited from modifying the map. If a
ConcurrentModificationException occurs, the function must either be changed to
avoid modifying the map, or the surrounding code should be rewritten to replace
uses of the compute- and merge methods with conventional Map methods such as
get and put.
See JDK-8227666 for further information.
Added Ability to Configure Third Port for Remote JMX (JDK-8234484)
core-svc/javax.management
JMX supports (explicit) remote network access through the configuration of two
network ports (either from the command line or in a property file), by setting
the following properties:
com.sun.management.jmxremote.port=<port#>
com.sun.management.jmxremote.rmi.port=<port#>
Note: If it is not specified, the second port will default to the first.
A third local port is also opened to accept (local) JMX connections. This port
previously had its number selected at random, which could cause port
collisions.
However, it is now possible to configure the third JMX port (local only) by
using:
com.sun.management.jmxremote.local.port=<port#>
New Option Added to jstatd for Specifying RMI Connector Port Number (
JDK-8196729)
core-svc/tools
A new -r <port> option has been added to the jstatd command to specify the RMI
connector port number. If a port number is not specified, a random available
port is used.
New Option Added to jcmd for Writing a gzipped Heap Dump (JDK-8237354)
core-svc/tools
A new integer option gz has been added to the GC.heap_dump diagnostic command.
If it is specified, it will enable the gzip compression of the written heap
dump. The supplied value is the compression level. It can range from 1
(fastest) to 9 (slowest, but best compression). The recommended level is 1.
JEP 378: Text Blocks (JDK-8236934)
Text blocks have been added to the Java language. A text block is a multi-line
string literal that avoids the need for most escape sequences, automatically
formats the string in a predictable way, and gives the developer control over
the format when desired.
New Options Added to jhsdb for debugd Mode (JDK-8196751)
hotspot/svc-agent
Three new options have been added to the jhsdb command for the debugd mode:
1. --rmiport <port> is used to specify a RMI connector port number. If a port
number is not specified, a random available port is used.
2. --registryport <port> is used to specify a RMI registry port number. This
option overrides the system property sun.jvm.hotspot.rmi.port. If a port
number is not specified, the system property is used. If the system
property is not set, the default port 1099 is used.
3. --hostname <hostname> is used to specify a RMI connector host name. The
value could be a hostname or an IPv4/IPv6 address. This option overrides
the system property java.rmi.server.hostname. If a host name not specified,
the system property is used. If the system property is not set, a system
host name is used.
Added Revocation Checking to jarsigner (JDK-8242060)
security-libs/java.security
A new -revCheck option has been added to the jarsigner command to enable
revocation checking of certificates.
Tools Warn If Weak Algorithms Are Used Before Restricting Them (JDK-8172404)
security-libs/java.security
The keytool and jarsigner tools have been updated to warn users about weak
cryptographic algorithms being used before they are disabled. In this release,
the tools issue warnings for the SHA-1 hash algorithm and 1024-bit RSA/DSA
keys.
SunJCE Provider Supports SHA-3 Based Hmac Algorithms (JDK-8172680)
security-libs/javax.crypto
The SunJCE provider has been enhanced to support HmacSHA3-224, HmacSHA3-256,
HmacSHA3-384, and HmacSHA3-512. Implementations for these algorithms are
available under the Mac and KeyGenerator services. The Mac service generates
the keyed-hash and the KeyGenerator service generates the key for the Mac.
New System Properties to Configure the TLS Signature Schemes (JDK-8242141)
security-libs/javax.net.ssl
Two new system properties have been added to customize the TLS signature
schemes in JDK. jdk.tls.client.SignatureSchemes has been added for the TLS
client side, and jdk.tls.server.SignatureSchemes has been added for the server
side.
Each system property contains a comma-separated list of supported signature
scheme names specifying the signature schemes that could be used for the TLS
connections.
The names are described in the "Signature Schemes" section of the Java Security
Standard Algorithm Names Specification.
Support for certificate_authorities Extension (JDK-8206925)
security-libs/javax.net.ssl
The "certificate_authorities" extension is an optional extension introduced in
TLS 1.3. It is used to indicate the certificate authorities (CAs) that an
endpoint supports and should be used by the receiving endpoint to guide
certificate selection.
With this JDK release, the "certificate_authorities" extension is supported for
TLS 1.3 in both the client and the server sides. This extension is always
present for client certificate selection, while it is optional for server
certificate selection.
Applications can enable this extension for server certificate selection by
setting the jdk.tls.client.enableCAExtension system property to true. The
default value of the property is false.
Note that if the client trusts more CAs than the size limit of the extension
(less than 2^16 bytes), the extension is not enabled. Also, some server
implementations do not allow handshake messages to exceed 2^14 bytes.
Consequently, there may be interoperability issues when
jdk.tls.client.enableCAExtension is set to true and the client trusts more CAs
than the server implementation limit.
Support for canonicalize in krb5.conf (JDK-8239385)
security-libs/org.ietf.jgss:krb5
The 'canonicalize' flag in the krb5.conf file is now supported by the JDK
Kerberos implementation. When set to true, RFC 6806 name canonicalization is
requested by clients in TGT requests to KDC services (AS protocol). Otherwise,
and by default, it is not requested.
The new default behavior is different from JDK 14 and previous releases where
name canonicalization was always requested by clients in TGT requests to KDC
services (provided that support for RFC 6806 was not explicitly disabled with
the sun.security.krb5.disableReferrals system or security properties).
Removed Features and Options
This section describes the APIs, features, and options that were removed in
Java SE 15 and JDK 15. The APIs described here are those that are provided with
the Oracle JDK. It includes a complete implementation of the Java SE 15
Platform and additional Java APIs to support developing, debugging, and
monitoring Java applications. Another source of information about important
enhancements and new features in Java SE 15 and JDK 15 is the Java SE 15 ( JSR
390) Platform Specification, which documents changes to the specification made
between Java SE 14 and Java SE 15. This document includes the identification of
removed APIs and features not described here. The descriptions below might also
identify potential compatibility issues that you could encounter when migrating
to JDK 15. See CSRs Approved for JDK 15 for the list of CSRs closed in JDK 15.
Removal of Terminally Deprecated Solaris-specific SO_FLOW_SLA Socket Option (
JDK-8244582)
core-libs/java.net
In this release, in conjunction with the removal of the Solaris port in JEP 381
, the JDK-specific socket option jdk.net.ExtendedSocketOptions.SO_FLOW_SLA,
which is only relevant to sockets on Solaris, and its supporting classes
SocketFlow and SocketFlow.Status, have been removed.
Removal of RMI Static Stub Compiler (rmic) (JDK-8225319)
core-libs/java.rmi
The RMI static stub compiler rmic has been removed. The rmic tool is obsolete
and has been deprecated for removal since JDK 13.
Removal of Deprecated Constant RMIConnectorServer.CREDENTIAL_TYPES (JDK-8213222
)
core-svc/javax.management
The terminally deprecated constant
javax.management.remote.rmi.RMIConnectorServer.CREDENTIAL_TYPE has been
removed. A filter pattern can be specified instead by using
RMIConnectorServer.CREDENTIALS_FILTER_PATTERN.
Removal of Nashorn JavaScript Engine (JDK-8236933)
The Nashorn JavaScript script engine, its APIs, and the jjs tool have been
removed. The engine, the APIs, and the tool were deprecated for removal in Java
11 with the express intent to remove them in a future release.
Obsolete -XX:UseAdaptiveGCBoundary (JDK-8228991)
hotspot/gc
The VM option UseAdaptiveGCBoundary is obsolete. Use of this option will
produce an obsolete option warning but will otherwise be ignored.
This option was previously disabled by default, and enabling it only had an
effect when also using -XX:+UseParallelGC. Enabling it was intended to provide
a performance benefit for some applications. However, it has been disabled by
default for a long time because of crashes and performance regressions.
Removal of DocuSign Root CA Certificate (JDK-8225068)
security-libs/java.security
The following expired DocuSign root CA certificate has been removed from the
cacerts keystore:
+ alias name "keynectisrootca [jdk]"
Distinguished Name: CN=KEYNECTIS ROOT CA, OU=ROOT, O=KEYNECTIS, C=FR
Removal of Comodo Root CA Certificate (JDK-8225069)
security-libs/java.security
The following expired Comodo root CA certificate has been removed from the
cacerts keystore:
+ alias name "addtrustclass1ca [jdk]"
Distinguished Name: CN=AddTrust Class 1 CA Root, OU=AddTrust TTP Network, O=AddTrust AB, C=SE
Removal of com.sun.net.ssl.internal.ssl.Provider Name (JDK-8219989)
security-libs/javax.net.ssl
The legacy SunJSSE provider name, "com.sun.net.ssl.internal.ssl.Provider" has
been removed and should no longer be used. The "SunJSSE" name should be used
instead. For example, SSLContext.getInstance("TLS", "SunJSSE").
Retired the Deprecated SSLSession.getPeerCertificateChain() Method
Implementation (JDK-8241039)
security-libs/javax.net.ssl
The implementation of the deprecated SSLSession.getPeerCertificateChain()
method has been removed from the JDK in the SunJSSE provider and the HTTP
client implementation. The default implementation of this method has been
changed to throw UnsupportedOperationException.
SSLSession.getPeerCertificateChain() is a deprecated method and will be removed
in a future release. To mitigate the removal compatibility impact, applications
should use the SSLSession.getPeerCertificates() method instead. For service
providers, please remove this method from the existing implementation, and do
not support this method in any new implementation.
Deprecated Features and Options
Additional sources of information about the APIs, features, and options
deprecated in Java SE 15 and JDK 15 include:
* The Deprecated API page identifies all deprecated APIs including those
deprecated in Java SE 15.
* The Java SE 15 ( JSR 390) specification specification documents changes to
the specification made between Java SE 14 and Java SE 15 that include the
identification of deprecated APIs and features not described here.
* JEP 277: Enhanced Deprecation provides a detailed description of the
deprecation policy. You should be aware of the updated policy described in
this document.
You should be aware of the contents in those documents as well as the items
described in this release notes page.
The descriptions of deprecated APIs might include references to the deprecation
warnings of forRemoval=true and forRemoval=false. The forRemoval=true text
indicates that a deprecated API might be removed from the next major release.
The forRemoval=false text indicates that a deprecated API is not expected to be
removed from the next major release but might be removed in some later release.
The descriptions below also identify potential compatibility issues that you
might encounter when migrating to JDK 15. See CSRs Approved for JDK 15 for the
list of CSRs closed in JDK 15.
Deprecated RMI Activation for Removal (JDK-8245068)
core-libs/java.rmi
The RMI Activation mechanism has been deprecated and may be removed in a future
version of the platform. RMI Activation is an obsolete part of RMI that has
been optional since Java 8. It allows RMI server JVMs to be started
("activated") upon receipt of a request from a client, instead of requiring RMI
server JVMs to be running continuously. Other parts of RMI are not deprecated.
See JEP 385 for further information.
Deprecated NSWindowStyleMaskTexturedBackground (JDK-8240995)
After an upgrade of the macOS SDK used to build the JDK, the behavior of the
apple.awt.brushMetalLook and textured Swing properties has changed. When these
properties are set, the title of the frame is still visible. It is recommended
that the apple.awt.transparentTitleBar property be set to true to make the
title of the frame invisible again. The apple.awt.fullWindowContent property
can also be used.
Please note that Textured window support was implemented by using the
NSTexturedBackgroundWindowMask value of NSWindowStyleMask. However, this was
deprecated in macOS 10.12 along with NSWindowStyleMaskTexturedBackground, which
was deprecated in macOS 10.14.
For additional information, refer to the following documentation:
* apple.awt.brushMetalLook: https://developer.apple.com/documentation/appkit/
nstexturedbackgroundwindowmask?language=objc
* apple.awt.transparentTitleBar: https://developer.apple.com/documentation/
appkit/nswindow/1419167-titlebarappearstransparent?language=objc
* apple.awt.fullWindowContent: https://developer.apple.com/documentation/
appkit/nsfullsizecontentviewwindowmask
Deprecated -XX:ForceNUMA Option (JDK-8243628)
hotspot/gc
The VM option ForceNUMA is deprecated. Use of this option will produce a
deprecation warning. This option will be removed in a future release.
This option has always been disabled by default. It exists to support testing
of NUMA-related code paths when running on a single node / UMA platform.
Disabled Biased-locking and Deprecated Biased-locking Flags (JDK-8231264)
hotspot/runtime
Biased locking has been disabled by default in this release. In addition, the
VM option UseBiasedLocking along with the VM options BiasedLockingStartupDelay,
BiasedLockingBulkRebiasThreshold, BiasedLockingBulkRevokeThreshold,
BiasedLockingDecayTime and UseOptoBiasInlining have been deprecated. The
options will continue to work as intended but will generate a deprecation
warning when they are used.
Biased locking might affect performance on applications that exhibit
significant amounts of uncontended synchronization, such as applications that
rely on older Java Collections APIs that synchronize on every access. Hashtable
and Vector are examples of these APIs. Use -XX:+BiasedLocking on the command
line to re-enable biased locking. Report any significant performance
regressions to Oracle with biased locking disabled.
Disable Native SunEC Implementation by Default (JDK-8237219)
security-libs/javax.crypto
The SunEC crypto provider no longer advertises curves that are not implemented
by using modern formulas and techniques. Arbitrary and named curves, listed at
the bottom of this note, are disabled. Commonly used named curves, secp256r1,
secp384r1, secp521r1, x25519, and x448, remain supported and enabled by SunEC
because they use modern techniques. Applications that still require the
disabled curves from the SunEC provider can re-enable them by setting the
System property jdk.sunec.disableNative to false. For example: java
-Djdk.sunec.disableNative=false ....
If this property is set to any other value, the curves will remain disabled.
Exceptions thrown when the curves are disabled will contain the message Legacy
SunEC curve disabled, followed by the name of the curve. Methods affected by
the change are KeyPair.generateKeyPair(), KeyAgreement.generateSecret(),
Signature.verify(), and Signature.sign(). These methods throw the same
exception class they had before when the curve was not supported.
The following curves are disabled: secp112r1, secp112r2, secp128r1, secp128r2,
secp160k1, secp160r1, secp160r2, secp192k1, secp192r1, secp224k1, secp224r1,
secp256k1, sect113r1, sect113r2, sect131r1, sect131r2, sect163k1, sect163r1,
sect163r2, sect193r1, sect193r2, sect233k1, sect233r1, sect239k1, sect283k1,

brainpoolP256r1 brainpoolP320r1, brainpoolP384r1, brainpoolP512r1
Added forRemoval=true to Previously Deprecated ContentSigner APIs (JDK-8242260)
security-libs/jdk.security
The ContentSigner and ContentSignerParameters classes in the com.sun.jarsigner
package support alternative signers and have been deprecated with forRemoval=
true. When the -altsigner or -altsignerpath options are specified, the
jarsigner tool produces a warning that these options are deprecated and will be
removed.
Known Issues
java.net.HttpClient Does Not Override Protocols Specified in SSLContext Default
Parameters (JDK-8239594)
core-libs/java.net
During the setup of new connections, java.net.http.HttpClient now uses the
default set of protocols provided by the SSLContext when negotiating the TLS
handshake. In the absence of any SSLParameters explicitly supplied to the
HttpClient.builder, the HttpClient has been updated to no longer override any
default-selected protocols in the SSLContext. As a result, the actual TLS
version that is negotiated might differ from that of previous releases, or it
might even succeed or fail to negotiate when it previously might not have.
[macos] Support for Notarizing jpackage app-image and dmg (JDK-8237490)
tools/jpackage
jpackage cannot create packages on macOS that are suitable for notarization.
Other Notes
The following notes describe additional changes and information about this
release. In some cases, the following descriptions provide links to additional
detailed information about an issue or a change.
Workaround for Windows GDI API's memory restrictions (JDK-8240654)
client-libs
It has been found that some Windows GDI functions don't support all types of
Java heap memory allocation schemes. This problem can cause repaint issues and
printing bugs. It has been worked around by allocating temporary buffers off
heap.
See: https://support.microsoft.com/en-us/help/4567569/
gdi-apis-may-fail-when-large-pages-or-vad-spanning-is-used
java.awt.Robot.delay() Method Completes With Interrupt Status Set When
Interrupted (JDK-8210231)
client-libs/java.awt
When it is interrupted, the implementation of the java.awt.Robot.delay() method
has been changed to complete with the interrupt status set.
If a thread is interrupted while waiting in the java.awt.Robot.delay() method,
then this method returns immediately with the interrupt status set. If the
interrupted status is already set, this method returns immediately with the
interrupt status set.
Optimized Empty Substring Handling (JDK-8240094)
core-libs/java.lang
The implementation of String.substring and related methods stripLeading and
stripTrailing have changed in this release to avoid redundantly creating a new
empty String. This may impact code that depends on unspecified behaviour and
the identity of empty sub-strings.
Lookup::defineClass Links the Class (JDK-8238195)
core-libs/java.lang.invoke
Lookup::defineClass is specified to throw LinkageError if a linkage error
occurs, but the implementation was not actually linking the class. In this
release, the implementation has been changed to link the class before
returning, so conforming to the specification. If Lookup::defineClass is called
to define a class that fails linking, LinkageError will be thrown.
DatagramPacket.getPort() Returns 0 When the Port Is Not Set (JDK-8237890)
core-libs/java.net
In this release, the default port number for a datagram packet has been changed
to 0. Previously, this value was -1, which was undocumented. The port can be
retrieved by using DatagramPacket::getPort.
DatagramSocket::disconnect Allows an Implementation to Throw
UncheckedIOException (JDK-8235783)
core-libs/java.net
Previously, DatagramChannel::disconnect threw an IOException while
DatagramSocket::disconnect did not. As a result, the DatagramChannel::socket
adapter, which calls DatagramChannel::disconnect, catches the thrown
IOException and rethrows it as an Error. However, this was undocumented
behavior and not user-friendly.
The DatagramChannel::socket adapter has been changed to throw an
UncheckedIOException, and the specification of DatagramSocket::disconnect has
been updated to document that an implementation may now throw an
UncheckedIOException. This ensures consistency in behavior between
DatagramSocket, DatagramChannel, and DatagramChannel::socket adapter.
Filtering and Ordering of Addresses Returned by Alternative Hosts File Name
Service Provider (JDK-8244958)
core-libs/java.net
In this release, the behavior of InetAddress.getAllByName has been modified
when the alternative hosts file name service is selected .
The JDK allows specifying an alternative host's file name service by using the
jdk.net.hosts.file system property. The implementation of the alternative name
service has been changed to take into account the values of the
java.net.preferIPv4Stack and java.net.preferIPv6Addresses system properties.
This affects the results returned by InetAddress.getAllByName when the host's
file name service is selected. For details about java.net.preferIPv4Stack and
java.net.preferIPv6Addresses, see Networking Properties in the API
documentation.
Modified the MS950 charset Encoder's Conversion Table (JDK-8232161)
core-libs/java.nio.charsets
In this release, some of the one-way byte-to-char mappings have been aligned
with the preferred mappings provided by the Unicode Consortium.
Support Monetary Grouping Separator in DecimalFormat/DecimalFormatSymbols (
JDK-8227313)
core-libs/java.text
DecimalFormat/DecimalFormatSymbols classes are now capable of dealing with
grouping separators for currency values. For example, the monetary grouping
separator for the German language used in Austria (the de-AT locale) is '.',
whereas the monetary grouping separator in other German locales is ' '.
ValueRange.of(long, long, long) Does Not Throw IAE on Invalid Inputs (
JDK-8239520)
core-libs/java.time
java.time.temporal.ValueRange.of() methods are now correctly throwing an
InvalidArgumentException on given invalid arguments. For example, of(5, 2, 10)
which is invalid because the minimum is greater than the smallest maximum, now
throws the exception.
localizedBy() Overrides Localized Values With Default Values (JDK-8244245)
core-libs/java.time
java.time.format.DateTimeFormatter.localizedBy(Locale) method now honors the
default locale values, such as Chronologyand/or DecimalStyle of the specified
locale argument.
For example, in previous JDK releases:
jshell> DateTimeFormatter.ofLocalizedDate(FormatStyle.FULL)
.localizedBy(Locale.forLanguageTag("fa"))
.format(LocalDate.now())
$3 ==> "جمعه 1 مهٔ 2020"
the numbers are in Arabic (Western) numerals.
In JDK 15:
jshell> DateTimeFormatter.ofLocalizedDate(FormatStyle.FULL)
.localizedBy(Locale.forLanguageTag("fa"))
.format(LocalDate.now())
$3 ==> "جمعه ۱ مهٔ ۲۰۲۰"
the numbers are in Extended Arabic-Indic numerals because it is the default
numbering system for the Farsi locale.
Performance Improvement for InflaterOutputStream.write (JDK-8242848)
core-libs/java.util.jar
InflaterOutputStream(OutputStream out, Inflater infl, int bufLen) allows for
specifying the decompressor and buffer size to be used.
InflaterOutputStream.write(byte[] b, int off, int len) was writing data using a
max buffer size of 512 bytes.
Starting with JDK 15 the buffer size specified via InflaterOutputStream
(OutputStream out, Inflater infl, int bufLen) will be used in calls to
InflaterOutputStream.write(byte[] b, int off, int len). If the buffer size is
not specified when invoking the InflaterOutputStreamconstructor, it will
default to 512 bytes.
Case Insensitive Matching Doesn't Work Correctly for Some Character Classes (
JDK-8214245)
core-libs/java.util.regex
The Java regular expression engine supports the case insensitive mode. When
this mode is turned on, the engine is supposed to match the input text without
regard to the case of the characters it consists of.
However, the current implementation of matching against some named character
classes (those that are encoded with p{name} or P{name} constructs) fails to
respect the case insensitive mode.
This fix makes these character classes behave consistently with respect to case
sensitivity. When the regular expression engine operates in the case
insensitive mode, the named character classes will match the input characters
without regard to their case: lower case, upper case, or title case.
Localized Time Zone Name Inconsistency Between English and Other Locales (
JDK-8236548)
core-libs/java.util:i18n
English time zone names provided by the CLDR locale provider are now correctly
synthesized following the CLDR spec, rather than substituted from the COMPAT
provider. For example, SHORT style names are no longer synthesized
abbreviations of LONG style names, but instead produce GMT offset formats.
Support for CLDR version 37 (JDK-8239480)
core-libs/java.util:i18n
Locale data based on Unicode Consortium's CLDR has been upgraded to their
version 37. For the detailed locale data changes, please refer to the Unicode
Consortium's CLDR release notes:
* http://cldr.unicode.org/index/downloads/cldr-37
Flags Controlling C1 Inlining Have New Names (JDK-8235673)
hotspot/compiler
A number of flags controlling inlining in the C1 and C2 compilers have been
split up into separate flags. The C2 compiler keeps the flags with the old
names, and the C1 compiler gets the new flags.
Old flags now only controlling C2
* MaxInlineLevel
* MaxRecursiveInlineLevel
* MaxInlineSize
* MaxTrivialSize
* InlineSmallCode
* FreqInlineSize
New flags for C1 that replace the old ones
* C1MaxInlineLevel
* C1MaxRecursiveInlineLevel
* C1MaxInlineSize
* C1MaxTrivialSize
Deprecation
If the old flags are used in a JDK build without the C2 compiler, a deprecation
warning will be printed.
JEP 377: ZGC: A Scalable Low-Latency Garbage Collector (Production) (
JDK-8209683)
hotspot/gc
The Z Garbage Collector (ZGC) is now ready for use in production and no longer
marked as an experimental feature. ZGC is enabled by using the -XX:+UseZGC
command-line option (using -XX:+UnlockExperimentalVMOptions is no longer
needed).
See JEP 377 for more details.
Improved Ergonomics for G1 Heap Region Size (JDK-8241670)
hotspot/gc
The default heap region size calculation has been changed to return larger
regions by default. The calculation still aims to have 2048 regions, but two
aspects have changed:
* Only the maximum heap size is considered. The old calculation also took the
initial heap size into consideration, but this can give unexpected behavior
when no heap size is set.
* The region size is rounded up to the nearest power of 2 instead of down.
This will return larger region sizes in cases where the maximum heap size
is not a power of 2.
These changes improve startup and runtime performance.
Disabling NUMA Interleaving on Windows (JDK-8245002)
hotspot/gc
-XX:+UseNUMAInterleaving has no effect on Windows in this release. It was found
that GDI APIs used by java2d don't support the memory reservation scheme used
for NUMA interleaving. The JVM detects this problem and both warns about this
and turns off NUMA interleaving. See: https://support.microsoft.com/en-us/help/
4567569/gdi-apis-may-fail-when-large-pages-or-vad-spanning-is-used
Disabling large pages on Windows (JDK-8245000)
hotspot/gc
-XX:+UseLargePages has no effect on Windows in this release. It was found that
GDI APIs used by java2d don't support large pages. The JVM detects this problem
and both warns about this and reverts to using small pages. See: https://
support.microsoft.com/en-us/help/4567569/
gdi-apis-may-fail-when-large-pages-or-vad-spanning-is-used
Field Layout Computation Changed (JDK-8237767)
hotspot/runtime
The way that field layout is computed has been changed, with more aggressive
optimizations to avoid unused gaps in instances. These new optimizations can be
disabled by using a new VM option -XX:-UseEmptySlotsInSupers.
For a limited time, it is possible to continue to use the old code to compute
field layout with a new VM option -XX:-UseNewFieldLayout. However, this option
has been deprecated in JDK 15 and the old code will be removed in a future
release.
Enable ShowCodeDetailsInExceptionMessages by default (JDK-8233014)
hotspot/runtime
The default of the flag ShowCodeDetailsInExceptionMessages was changed to
'true'. The helpful NullPointerException messages of JEP 358 are now printed by
default. The messages contain snippets of the code where the
NullPointerException was raised.
App deployers should double check the output of their web applications and
similar usage scenarios. The NullPointerException message could be included in
application error messages or be displayed by other means in the app. This
could give remote attackers valuable hints about a potential vulnerable state
of the software components being used.
An example message is 'Cannot read field "c" because "a.b" is null'. The
attacker knows that field b of a contains null which might be unintended and
offer an opportunity for an attack. For more details of what the message can
contain see the above mentioned JEP 358.
Signature and SignatureSpi Get Parameter Methods May Return null When
Unsupported (JDK-8243424)
security-libs/java.security
Signature.getParameters() and SignatureSpi.engineGetParameters() may return
null if the underlying provider does not support returning the parameters as
AlgorithmParameters. For further details, see the Signature and SignatureSpi
method descriptions.
SunPKCS11 Initialization With NSS When External FIPS Modules Are in Security
Modules Database (JDK-8238555)
security-libs/javax.crypto:pkcs11
The SunPKCS11 security provider can now be initialized with NSS when
FIPS-enabled external modules are configured in the Security Modules Database
(NSSDB). Before this change, when such a library was configured for NSS in
non-FIPS mode, the SunPKCS11 provider would throw a RuntimeException with the
message "FIPS flag set for non-internal module".
This change allows the JDK to work properly with recent NSS releases in GNU/
Linux operating systems when the system-wide FIPS policy is turned on.
Default SSLEngine Should Create in Server Role (JDK-8237474)
security-libs/javax.net.ssl
In JDK 11 and later, javax.net.ssl.SSLEngine by default used client mode when
handshaking. As a result, the set of default enabled protocols may differ to
what is expected. SSLEngine would usually be used in server mode. From this JDK
release onwards, SSLEngine will default to server mode. The
javax.net.ssl.SSLEngine.setUseClientMode(boolean mode) method may be used to
configure the mode.
New in 2020.08.2:

New in 2020.06:
+ SPECIAL NOTES:
+ Results of `dir` routine called with dirty base path are presented
as cleaned up for some paths (like `///` or `a/../a`) unlike
before. While compatibility with most of other cases is preserved
and no ecosystem fallout was observed, be cautious of the possible
observable changes if the code does not clean dirty paths using `cleanup` method.
+ Since this release, when you start Raku with "-" as a single positional parameter, it
will now check if STDIN is connected to a terminal. If it is, then
the REPL will be started, rather than appearing to freeze waiting
for the user to enter something and issue an EOF. If STDIN is *not*
connected to a terminal, then Raku will read from STDIN and process
that as the source of a program.
+ The `run` routine, `Proc.spawn` and `Proc::Async.new` are
extended with a new argument `:$win-verbatim-args` defaulting to
`False`. If the argument is left off or set to False, the
arguments are quoted according to the Microsoft convention. This
is identical to Rakus previous behavior and thus backwards
compatible. When passing True the passed arguments are
concatenated with a single space. No other processing takes
place. This allows to manually quote the arguments as necessary.
+ Changes:
+ Support verbatim argument handling for `Proc` [709941c6][9a75738f]
+ Signatures of `slurp` and `spurt` routines not accepting redundant arguments is
now compile time error rather than run-time one [22f43444]

+ Add CACHEDIR.TAG to mark cache dirs as cache [37646b86][c3bdb617][ef90599e]
+ Improve GNU C++ name mangling [4f672c27]
+ Make `Instant.raku` output simpler [c0b5fb28]
+ Improve smartmatching against `Mu`/`Any`/`Junction` types
