Changelog:
10.7.2
Fixing out-of-sink of file positions when mixing 'search' and 'seek'
with 'read-line' on IO-streams introduced a new errror making
the newlisp-10.x.x/examples/upload.cgi script fail.
10.7.3
Supress loading of startup init.lsp when -h option is present. Before
only the -n and -x options supressed init.lsp.
Change in modules/gsl.lsp to make it work on locales using comma separator.
Ability to use 'open', 'rename-file', 'delete-file', 'make-dir' and
'remove-dir' with UTF16 filenames in UTF8 versions on Windows when
using the UTF8 version of newLISP. The functions 'file-info', 'file?',
'change-dir' and 'dir? already worked on UTF16 filenames when using the UTF8
version of newLISP on Windows.
Thanks to Michael Sabin who started the work a few years back writing the
win-path.c file with functions translating between UTF8 and UTF16.
When using the UTF8 version of newLISP on Windows in a command shell, that
command shell program also should be able to handle/display UTF8 (not UTF16).
On Windows and Linux the Java based frontend newLISP-GS handles UTF8.
On Mac OS the terminal program handles UTF8.
Fixed a wrong 'symbol protected message' when a protected symbol is
part of a nested espression, but not a symbol with its content to be
modified.
New modules/postscript.lsp changes description of ps:drawto.
Fixed flushing problem on 'print' to stdout on Mac OS and other BSDs.
'(read-key true)' with the 'true' parameter is now non-blocking.
(trim str) on some strings containing 0's would overrun memory and 0's
where not trimmed from the left. All character <= 32 (space) should
be trimmed from the left and right ends of the string buffer. When the
entire string is valid ASCII or UTF-8 with no 0s, ‘trim’ behaves
like in older versions.
10.7.4
When starting newlisp in -http-safe server mode HTTP_PUT and HTTP_DELETE
requests will not be served. This will cause 'write-file' and 'delete-file'
in url syntax, 'put-url' and 'delete-url' functions issued from a newLISP
client to return the text message "Server in safe mode".
New file qa-specific-tests/qa-share.lsp .
New guiserver.jar v 1.67 compiled with java 1.6
Still problems on macOS, some unrelated to change to image/icon load change
Added REQUEST_URI to environment variables in webserver mode.
Removed code introduced in 10.7.2 to syncronize file poisitons of C FILE stream
and raw file handle operations. Syncronization still seem s to work on cases
tested, but may not work in all cases mixing 'read-line' and 'seek'.
Changes for separately packaged Java Guiserver and elimination of installers.
(rotate theList -offsetOfRotation) was buggy
10.7.5
In getPutPostDeleteUrl(....) sock wasn't closed when returning with webError(..)
compareLists() in nl-math.c did not take list lengths into account. Also update
of qa-dot for relevant cases.
Version 10.16.3 'Dubnium' (LTS):
Notable changes
This is a security release.
Node.js, as well as many other implementations of HTTP/2, have been found vulnerable to Denial of Service attacks. See https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-002.md for more information.
Vulnerabilities fixed:
CVE-2019-9511 “Data Dribble”: The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
CVE-2019-9512 “Ping Flood”: The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
CVE-2019-9513 “Resource Loop”: The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU, potentially leading to a denial of service.
CVE-2019-9514 “Reset Flood”: The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both, potentially leading to a denial of service.
CVE-2019-9515 “Settings Flood”: The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
CVE-2019-9516 “0-Length Headers Leak”: The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory, potentially leading to a denial of service.
CVE-2019-9517 “Internal Data Buffering”: The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both, potentially leading to a denial of service.
CVE-2019-9518 “Empty Frames Flood”: The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU, potentially leading to a denial of service.
net/http: Denial of Service vulnerabilities in the HTTP/2 implementation
net/http and golang.org/x/net/http2 servers that accept direct connections from
untrusted clients could be remotely made to allocate an unlimited amount of
memory, until the program crashes. Servers will now close connections if the
send queue accumulates too many control messages.
The issues are CVE-2019-9512 and CVE-2019-9514, and Go issue golang.org/issue/33606.
Thanks to Jonathan Looney from Netflix for discovering and reporting these issues.
This is also fixed in version v0.0.0-20190813141303-74dc4d7220e7 of
golang.org/x/net/http2.
net/url: parsing validation issue
url.Parse would accept URLs with malformed hosts, such that the Host field
could have arbitrary suffixes that would appear in neither Hostname() nor
Port(), allowing authorization bypasses in certain applications. Note that URLs
with invalid, not numeric ports will now return an error from url.Parse.
The issue is CVE-2019-14809 and Go issue golang.org/issue/29098.
Thanks to Julian Hector and Nikolai Krein from Cure53, and Adi Cohen (adico.me)
for discovering and reporting this issue.

This should help with some people's problems with the rust builds being
excessively long, and if we ever run into compatibility problems between
rust's llvm-current and our shipped version it should be easy to switch
on the internal LLVM by default again.
I've been using this for some time with Firefox without problems.

* bug fix: restored sb-thread support on OpenBSD.
Changes between version 1.4.12 and version 1.4.13
* minor incompatible change: PRINT-TYPE and PRINT-TYPE-SPECIFIER are not
exported from SB-EXT. These were never announced, so this change would
only affects users who discovered these undocumented functions.

Changes between version 1.4.10 and version 1.4.11
* minor incompatible change: changes to the (internal) assembler on x86
and x86-64 may cause problems to some low-level third-party libraries:
new macro EA for defining an effective address, without size
information;
an explicit size modifier is now needed for MOVSX and MOVSZ
instructions;
MOVD and MOVQ move a single size of operand by definition.
* enhancement: support the latest MinGW (#1786731, reported by il71)
* enhancement: checks for modifications of constants can now be done in
local (FLET/LABELS) functions.
* optimization: improved type checking routines for various compound types.
* optimization: array bound checks are elided on vectors when the index
is known to be less than the length, including LOOP ACROSS.
* optimization: the register allocator's use of temporaries is somewhat
improved.
* optimization: checking widetags involves fewer conditional jumps on x86
and x86-64.

* optimization: better bounds-checking on x86[-64] and ARM64.
* optimization: adding 1 to or subtracting 1 from a fixnum variable does
not cons.
* bug fixes: fix a number of bugs revealed by random testing (#1782826,
#1779878, #1779737)
Changes between version 1.4.8 and version 1.4.9
* enhancement: SB-COVER instrumentation for x86[-64] has signficantly
less overhead. The performance penalty for 64-bit code has been
measured at around 30% slower than uninstrumented code as contrasted
with slowdowns in excess of 100% previously.
* enhancement: tracing a generic function with the :METHODS T option
produces output corresponding to each method called under the default
:ENCAPSULATE NIL tracing implementation.
* bug fix: updated TRACE documentation. (#574614 was actually already
fixed, but there were other issues.)
* bug fix: fixed x86 GC bug causing heap corruption. (#1749369)
* bug fix: improved compatibility with macOS High Sierra and graphical
applications.
Changes between version 1.4.7 and version 1.4.8
* bug fix: redefinition of method combinations now does the expected
thing; generic functions using that method combination have their
effective methods lazily recomputed according to the new definition
of the method combination. (Reported by Didier Verna at ELS 2018)
* bug fix: :arguments argument to the long form of DEFINE-METHOD-COMBINATION
is now implemented more correctly, supporting suppliedp variables and
&optional defaults. (Reported by Bruno Haible, #309084)
Changes between version 1.4.6 and version 1.4.7
* enhancement: better handling of unknown keyword arguments (#1750466)
* enhancement: namestrings can now be computed for certain pathnames
that previously did not have namestrings because of #\. characters
in their name and/or type components.
* bug fix: compiling a SLEEP call with a float positive infinity
argument no longer causes an internal error (#1754081)
* bug fix: keyword arguments provided to a generic function with
EQL-specialized methods are checked more correctly (reported by
Syll, #1760987)
Changes between version 1.4.5 and version 1.4.6
* enhancement: DISASSEMBLE on a symbol naming a macro will
disassemble the expander, not the code that traps attempted
FUNCALL of the macro.
* enhancement: The sb-sprof contrib now provides an experimental
interface for accessing collected profiler data.
* enhancement: The instruction-level profiling of the sb-prof contrib
annotates the disassembler output more efficiently.
* optimization: improved dynamic-extent handling of nested variables.
Changes betweenNew in version 1.4.5
* minor incompatible change: building with/without the :sb-package-locks
feature is no longer an option. Package locks are always compiled in,
and removing :sb-package-locks from *features* will have no effect.
* enhancement: FIND-PACKAGE does not acquire a mutex
* enhancement: cheneygc can perform heap relocation on startup
* enhancement: in threaded builds, finalizers execute in a system-internal
thread so that a user thread which invokes GC is unblocked from
performing work as soon it returns from GC and invokes any post-GC hooks.
As such, it is more important than before to avoid assumptions about
special variable bindings in finalizers, even in single-threaded code.
* optimization: faster (funcall (or function symbol)) on x86-64.
Changes between version 1.4.3 and version 1.4.4
* bug fix: pathname accessors such as PATHNAME-DIRECTORY work on
SYNONYM-STREAMs.
* bug fix: (pathname-{device,directory,name,type} ... :case :common) works
as expected. In particular MAKE-PATHNAME composed with the accessors
roundtrips properly when both use the same :case. (#1739906)
* bug fix: DIRECTORY no longer gets confused when the value of
*DEFAULT-PATHNAME-DEFAULTS* has a name or type component. (#1740563)
* bug fix: pattern pieces in pathname components are correctly
escaped during unparsing.
* bug fix: DELETE-DIRECTORY no longer signals an error when the
directory is supplied as a pathname with name and/or type
components containing escaped characters. (#1740624)
* bug fix: weak hash-tables no longer cause GC time to scale
superlinearly (#1241771)
* bug fix: CANCEL-FINALIZATION operates in approximately constant
time per operation (#1587983)
* bug fix: big-endian MIPS systems now (mostly) work again (broken
since 1.3.14.x).
* bug fix: backtrace from arg-count errors on systems other than x86,
x86-64, ARM, and ARM64 now works again.
* bug fix: backtrace from asynchronous interrupts on non-x86,
non-x86-64 systems should now be more reliable.
* enhancement: warnings and errors referring to bindings established by
LET, LET*, FLET and LABELS point to the offending form more accurately.
* enhancement: backtrace for invalid argument count produces the
exact supplied arguments including the extra ones on all platforms
(no longer just x86, x86-64, ARM, and ARM64).
Mypy 0.720 was released. This release uses the new semantic analyzer by
default, adds a flag to warn about unreachable code, and has other improvements
and bug fixes.
what is new for perl v5.30.0
Core Enhancements
Limited variable length lookbehind in regular expression pattern matching is now experimentally supported
Using a lookbehind assertion (like "(?<=foo?)" or "(?<!ba{1,9}r)" previously would generate an error and
refuse to compile. Now it compiles (if the maximum lookbehind is at most 255 characters), but raises a
warning in the new "experimental::vlb" warnings category. This is to caution you that the precise behavior
is subject to change based on feedback from use in the field.
See "(?<=pattern)" in perlre and "(?<!pattern)" in perlre.
The upper limit "n" specifiable in a regular expression quantifier of the form "{m,n}" has been doubled to 65534
The meaning of an unbounded upper quantifier "{m,}" remains unchanged. It matches 2**31 - 1 times on most
platforms, and more on ones where a C language short variable is more than 4 bytes long.
Unicode 12.1 is supported
Because of a change in Unicode release cycles, Perl jumps from Unicode 10.0 in Perl 5.28 to Unicode 12.1 in
Perl 5.30.
For details on the Unicode changes, see <https://www.unicode.org/versions/Unicode11.0.0/> for 11.0;
<https://www.unicode.org/versions/Unicode12.0.0/> for 12.0; and
<https://www.unicode.org/versions/Unicode12.1.0/> for 12.1. (Unicode 12.1 differs from 12.0 only in the
addition of a single character, that for the new Japanese era name.)
The Word_Break property, as in past Perl releases, remains tailored to behave more in line with expectations
of Perl users. This means that sequential runs of horizontal white space characters are not broken apart,
but kept as a single run. Unicode 11 changed from past versions to be more in line with Perl, but it left
several white space characters as causing breaks: TAB, NO BREAK SPACE, and FIGURE SPACE (U+2007). We have
decided to continue to use the previous Perl tailoring with regards to these.
Wildcards in Unicode property value specifications are now partially supported
You can now do something like this in a regular expression pattern
qr! \p{nv= /(?x) \A [0-5] \z / }!
which matches all Unicode code points whose numeric value is between 0 and 5 inclusive. So, it could match
the Thai or Bengali digits whose numeric values are 0, 1, 2, 3, 4, or 5.
This marks another step in implementing the regular expression features the Unicode Consortium suggests.
Most properties are supported, with the remainder planned for 5.32. Details are in "Wildcards in Property
Values" in perlunicode.
qr'\N{name}' is now supported
Previously it was an error to evaluate a named character "\N{...}" within a single quoted regular expression
pattern (whose evaluation is deferred from the normal place). This restriction is now removed.
Turkic UTF-8 locales are now seamlessly supported
Turkic languages have different casing rules than other languages for the characters "i" and "I". The
uppercase of "i" is LATIN CAPITAL LETTER I WITH DOT ABOVE (U+0130); and the lowercase of "I" is LATIN SMALL
LETTER DOTLESS I (U+0131). Unicode furnishes alternate casing rules for use with Turkic languages.
Previously, Perl ignored these, but now, it uses them when it detects that it is operating under a Turkic
UTF-8 locale.
It is now possible to compile perl to always use thread-safe locale operations.
Previously, these calls were only used when the perl was compiled to be multi-threaded. To always enable
them, add
-Accflags='-DUSE_THREAD_SAFE_LOCALE'
to your Configure flags.
Eliminate opASSIGN macro usage from core
This macro is still defined but no longer used in core
"-Drv" now means something on "-DDEBUGGING" builds
Now, adding the verbose flag ("-Dv") to the "-Dr" flag turns on all possible regular expression debugging.
Incompatible Changes
Assigning non-zero to $[ is fatal
Setting $[ to a non-zero value has been deprecated since Perl 5.12 and now throws a fatal error. See
"Assigning non-zero to $[ is fatal" in perldeprecation.
Delimiters must now be graphemes
See "Use of unassigned code point or non-standalone grapheme for a delimiter." in perldeprecation
Some formerly deprecated uses of an unescaped left brace "{" in regular expression patterns are now illegal
But to avoid breaking code unnecessarily, most instances that issued a deprecation warning, remain legal and
now have a non-deprecation warning raised. See "Unescaped left braces in regular expressions" in
perldeprecation.
Previously deprecated sysread()/syswrite() on :utf8 handles is now fatal
Calling sysread(), syswrite(), send() or recv() on a ":utf8" handle, whether applied explicitly or
implicitly, is now fatal. This was deprecated in perl 5.24.
There were two problems with calling these functions on ":utf8" handles:
o All four functions only paid attention to the ":utf8" flag. Other layers were completely ignored, so a
handle with ":encoding(UTF-16LE)" layer would be treated as UTF-8. Other layers, such as compression
are completely ignored with or without the ":utf8" flag.
o sysread() and recv() would read from the handle, skipping any validation by the layers, and do no
validation of their own. This could lead to invalidly encoded perl scalars.
my() in false conditional prohibited
Declarations such as "my $x if 0" are no longer permitted.
Fatalize $* and $#
These special variables, long deprecated, now throw exceptions when used.
Fatalize unqualified use of dump()
The "dump()" function, long discouraged, may no longer be used unless it is fully qualified, i.e.,
"CORE::dump()".
Remove File::Glob::glob()
The "File::Glob::glob()" function, long deprecated, has been removed and now throws an exception which
advises use of "File::Glob::bsd_glob()" instead.
"pack()" no longer can return malformed UTF-8
It croaks if it would otherwise return a UTF-8 string that contains malformed UTF-8. This protects against
potential security threats. This is considered a bug fix as well.
Any set of digits in the Common script are legal in a script run of another script
There are several sets of digits in the Common script. "[0-9]" is the most familiar. But there are also
"[\x{FF10}-\x{FF19}]" (FULLWIDTH DIGIT ZERO - FULLWIDTH DIGIT NINE), and several sets for use in
mathematical notation, such as the MATHEMATICAL DOUBLE-STRUCK DIGITs. Any of these sets should be able to
appear in script runs of, say, Greek. But the design of 5.30 overlooked all but the ASCII digits "[0-9]",
so the design was flawed. This has been fixed, so is both a bug fix and an incompatibility.
All digits in a run still have to come from the same set of ten digits.
JSON::PP enables allow_nonref by default
As JSON::XS 4.0 changed its policy and enabled allow_nonref by default, JSON::PP also enabled allow_nonref
by default.
Deprecations
In XS code, use of various macros dealing with UTF-8.
This deprecation was scheduled to become fatal in 5.30, but has been delayed to 5.32 due to problems that
showed up with some CPAN modules. For details of what's affected, see perldeprecation.
Performance Enhancements
o Translating from UTF-8 into the code point it represents now is done via a deterministic finite
automaton, speeding it up. As a typical example, "ord("\x7fff")" now requires 12% fewer instructions
than before. The performance of checking that a sequence of bytes is valid UTF-8 is similarly improved,
again by using a DFA.
o Eliminate recursion from finalize_op().
o A handful of small optimizations related to character folding and character classes in regular
expressions.
o Optimization of "IV" to "UV" conversions.
o Speed up of the integer stringification algorithm by processing two digits at a time instead of one.
o Improvements based on LGTM analysis and recommendation.
o Code optimizations in regcomp.c, regcomp.h, regexec.c.
o Regular expression pattern matching of things like "qr/[^a]/" is significantly sped up, where a is any
ASCII character. Other classes can get this speed up, but which ones is complicated and depends on the
underlying bit patterns of those characters, so differs between ASCII and EBCDIC platforms, but all case
pairs, like "qr/[Gg]/" are included, as is "[^01]".
The canonical form [1] of an R package Makefile includes the
following:
- The first stanza includes R_PKGNAME, R_PKGVER, PKGREVISION (as
needed), and CATEGORIES.
- HOMEPAGE is not present but defined in math/R/Makefile.extension to
refer to the CRAN web page describing the package. Other relevant
web pages are often linked from there via the URL field.
This updates all current R packages to this form, which will make
regular updates _much_ easier, especially using pkgtools/R2pkg.

Version 10.16.2 'Dubnium' (LTS)
Notable changes
This release patches a regression in the OpenSSL upgrade to 1.1.1c that causes intermittent hangs in machines that have low entropy.
this might be the cause of weird missing -lz on the latest SmartOS bulk
build, which appears to use this package (e.g. graphics/glitz).
Bump PKGREVISION.
for ansi.h on netbsd.
gcc{7,8}: document same patch that already existed was upstreamed.
This patch is necessary to build GCC on NetBSD >= 9.0, since changes
to ansi.h resulted in not using the same include guards.
Fixes PR toolchain/54362
This is based on an already upstreamed patched that exists in GCC>9.0.
GCC stddef.h relied on the include guards of headers, and those were
changed in netbsd 9.0, so these packages no longer build.
Since we are using a bootstrap GCC, we also need to patch the headers
in the bootstrap fixincludes, patching the package is not sufficient.

Erlang/OTP 22 is a new major release with new features and improvements as well as incompatibilities.
For a deeper dive into the hightligts of the OTP 22 release, you can read our blog here:
http://blog.erlang.org/OTP-22-Highlights/
Potential Incompatibilities
gen_* behaviours: If logging of the last N messages through sys:log/2,3 is active for the server, this log is included in the terminate report.
reltool: A new element, Opts, can now be included in a rel tuple in the reltool release specific configuration format: {rel, Name, Vsn, RelApps, Opts}.
All external pids/ports/refs created by erlang:list_to_pid and similar functions now compare equal to any other pid/port/ref with same number from that node.
The old legacy erl_interface library is deprecated as of OTP 22, and will be removed in OTP 23. This does not apply to the ei library.
VxWorks is deprecated as of OTP 22 and will be removed in OTP 23.
Erts:
Support for Erlang Distribution protocol to split the payload of large signals into several fragments.
ETS option write_concurrency now also effects and improves scalability of ordered_set tables.
The length/1 BIF used to calculate the length of the list in one go without yielding, even if the list was very long. Now it yields when called with long lists.
A new (still experimental) module socket is introduced. It is implemented as a NIF and the idea is that it shall be as "close as possible" to the OS level socket interface.
Added the NIF function enif_term_type, which helps avoid long sequences of enif_is_xyz by returning the type of the given term. This is especially helpful for NIFs that serialize terms, such as JSON encoders, where it can improve both performance and readability.
Compiler:
The compiler has been rewritten to internally use an intermediate representation based on Static Single Assignment (SSA). The new intermediate representation makes more optimizations possible.
The binary matching optimizations are now applicable in many more circumstances than before.
Type optimizations are now applied across local function calls, and will remove a lot more redundant type tests than before.
All compiler options that can be given in the source file can now be given in the option list on the command line for erlc.
In OTP 22, HiPE (the native code compiler) is not fully functional. The reasons for this are new BEAM instructions for binary matching that the HiPE native code compiler does not support. If erlc is invoked with the +native option, and if any of the new binary matching instructions are used, the compiler will issue a warning and produce a BEAM file without native code.
Standard libraries:
Cover now uses the counters module instead of ets for updating counters. The new function cover:local_only/0 allows running Cover in a restricted but faster local-only mode. The increase in speed will vary depending on the type of code being cover-compiled, as an example the compiler test suite runs more than twice as fast with the new Cover.
A simple socket API is provided through the socket module. This is a low level API that does *not* replace gen_[tcp|udp|sctp]. It is intended to *eventually* replace the inet driver. It also provides a basic API that facilitates the implementation of other protocols than TCP, UDP and SCTP. Known issues are; No support for the Windows OS (currently), a small term leakage. This feature will be classed as experimental in OTP 22.
SSL: now uses the new logger API, including log levels and verbose debug logging.
SSL: Basic support for TLS 1.3 Server for experimental use.
crypto: The new hash_info/1 and cipher_info/1 functions returns maps with information about the hash or cipher in the argument.

Update to the canonical form of an R package and fix the LICENSE
field. Note that this package is now included within the base R
package, so it is marked with CONFLICTS.
This repo is a continuation of the bsd-port tree, still maintained by
the FreeBSD ports java people.
It is forked from (and merges regularly from) AdoptOpenJDK.
They accept patches for other BSDs, so we should see if we have anything
in our tree worth contributing.
As a side effect, this changes updates openjdk8 to u222.
1 New and Improved Features
1.1 Direct Linking
Direct linking can be enabled with -Dclojure.compiler.direct-linking=true
Direct linking allows functions compiled with direct linking on to make direct static method calls to most other functions, instead of going through the var and the Fn object. This can enable further optimization by the jit, at a cost in dynamism. In particular, directly-linked calls will not see redefinitions.
With this change, clojure.core itself is compiled with direct linking and therefore other namespaces cannot redefine core fns and have those redefinitions seen by core code.
A new metadata key ^:redef is provided. A function declared with this key can be redefined and will never be direct linked. Also, functions declared as ^:dynamic will never be direct linked.
CLJ-1809
CLJ-1805
CLJ-1854
CLJ-1856
1.2 String Functions
Several new string functions were added to clojure.string to increase portability and reduce the need for Java interop calls:
index-of - search for the index of a char or string in a string
last-index-of - search for the index of a char or string backwards in a string
starts-with? - true if string starts with a substring
ends-with? - true if string ends with a substring
includes? - true if string includes a substring
CLJ-1449
1.3 Socket Server and REPL
The Clojure runtime now has the ability to start a socket server at initialization based on system properties. One expected use for this is serving a socket-based REPL, but it also has many other potential uses for dynamically adding server capability to existing programs without code changes.
A socket server will be started for each JVM system property like clojure.server.<server-name>. The value for this property is an edn map representing the configuration of the socket server with the following properties:
address - host or address, defaults to loopback
port - positive integer, required
accept - namespaced symbol of function to invoke on socket accept, required
args - sequential collection of args to pass to accept
bind-err - defaults to true, binds *err* to socket out stream
server-daemon - defaults to true, socket server thread doesn't block exit
client-daemon - defaults to true, socket client thread doesn't block exit
Additionally, there is a repl function provided that is slightly customized for use with the socket server in clojure.core.server/repl.
Following is an example of starting a socket server with a repl listener. This can be added to any existing Clojure program to allow it to accept external REPL clients.
-Dclojure.server.repl="{:port 5555 :accept clojure.core.server/repl}"
An example client you can use to connect to this socket repl is telnet:
$ telnet 127.0.0.1 5555
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
user=> (println "hello")
hello

Changes in 2.2.6 (since 2.2.5)
* Bug fixes
** Fix regression introduced in 2.2.5 that would break HTTP servers
Guile 2.2.5 introduced a bug that would break the built-in HTTP server
provided by the (web server) module. Specifically, HTTP servers would
hang while reading requests. See <https://bugs.gnu.org/36350>.
** 'strftime' and 'strptime' honor the current locale encoding
Until now these procedures would wrongfully assume that the locale
encoding is always UTF-8. See <https://bugs.gnu.org/35920>.
** Re-export 'current-load-port'
This procedure was erroneously removed in the 2.2 series but was still
documented.
** Minor documentation mistakes were fixed
Changelog:
Changes affecting backwards compatibility
All strutils.rfind procs now take start and last like strutils.find with the same data slice/index meaning. This is backwards compatible for calls not changing the rfind start parameter from its default. (#11487)
In the unlikely case that you were using rfind X, start=N, or rfind X, N, then you need to change that to rfind X, last=N or rfind X, 0, N. (This should minimize gotchas porting code from other languages like Python or C++.)
On Windows stderr/stdout/stdin are not opened as binary files anymore. Use the switch -d:nimBinaryStdFiles for a transition period.
Breaking changes in the standard library
Mac OS X / BSD: TSa_Family is now the uint8 type, so type conversions like x.sin_family = uint16 toInt(nativesockets.AF_INET) need to be changed into x.sin_family = TSa_Family toInt(nativesockets.AF_INET).
Library additions
toOpenArray is now available for the JS target.

This also addresses PR/54316.
Please note: this bootstrap is built against 8.99.50, i.e. fairly
recent -current. This should make it possible to build rust on
this OS version. The previous bootstrap kit was built against
8.99.35, and apparently a C++ update happened since then making
the older bootstrap kit unusable on a fresh, new -current.

"Commodore BASIC" (cbmbasic) is a 100% compatible version of Commodore's
version of Microsoft BASIC 6502 as found on the Commodore 64. You can use it
in interactive mode or pass a BASIC file as a command line parameter.
cbmbasic does not emulate 6502 code; all code is completely native. On a
1 GHz CPU you get about 1000x speed compared to a 1 MHz 6502.
In 5.1.0 the binary-version was bumped to 11. Update OWN_DIRS
accordingly and introduce CHICKEN_BINARY_VERSION variable to
automatically adjust OWN_DIRS and PLIST.

Changelog:
5.1.0
- Core libraries
- Symbols ending or starting with a colon are now always pipe-quoted
when written by `write` to ensure they can be read back with a
different keyword-style setting.
- Read-write invariance of special symbols starting with #! other
than #!key, #!rest or #!optional is now preserved (#1572).
- When using (set-file-position!) on a port, its EOF status will now
be reset.
- In (chicken file posix), the values of perm/irgrp, perm/iwgrp,
perm/ixgrp, perm/iroth, perm/iwoth and perm/ixoth are now correctly
defined (they were all for "usr"; #1602, thanks to Eric Hoffman).
- In (chicken file posix), `file-truncate` now accepts also accepts
port objects, for consistency with other file procedures.
All such procedures from (chicken file posix) now have the correct
types in types.db (fixes#1609, thanks to Robert Jensen).
- Add the system-config-directory and system-cache-directory procedures
in the chicken.platform module. These procedures follow the XDG
specification and also give sensible results on Windows.
- Fix get-environment from (chicken process-context) to raise an
error when passed #f instead of segfaulting.
- Qualified symbols (##foo#bar style) are no longer encoded by a
byte prefix inside the symbol name. This ensures read-write
invariance of symbols which start with a low-byte character
(fixes#1077, except for keywords, which start with NUL bytes).
- Fix a missing export (list->s64vector) in SRFI-4.
- Runtime system
- Keywords are now distinct types; they are not a subtype of symbols.
- Use arc4random on FreeBSD (thanks to Tobias Kortkamp and gahr)
- Removed the unused, undocumented (and incorrect!) C functions
C_delete_symbol_table and C_set_symbol_table.
- Continuations which discard additional values beyond the first no
longer accept multiple values via direct invocation after being
captured through `call/cc`, only via `values` (revert of #1390,
due to #1601)
- SRFI-4 vector predicates, reference, set and length procedures
should now be faster in tight loops as they're inlineable (#757).
- Keywords are now interned in a separate keyword table, not in the
standard symbol table. This brings full read-write invariance
for symbols (they can now also start with NUL bytes). Keywords
no longer have plists. Fixes#1576.
- Increased the "binary compatibility version" to 11.
- Compiler
- Restored optimized implementations of =, +, -, /, * and quotient in
fixnum-arithmetic mode (fixes#1604 mostly; thanks to "chickendan").
- Added an optimization pass for reducing the amount of boxing of
intermediate floating point values, enabled by the "-lfa2" compiler
option.
- The "lfa2" pass is now enabled at optimization levels 2 or higher.
- Module system
- When you try to import the module you are currently defining into
itself, an error will be raised. This prevents an infinite loop in
the compiler when later trying to import that same module (fixes
#1506, thanks to Kristian Lein-Mathisen).
- Foreign function interface
- Improved hygiene in FFI macro expansions, which means you don't
have to import "scheme" or "(chicken base)" for them to work.
- Type system
- It is now possible to quote free variables in type declarations,
which acts as shorthand for `forall' (thanks to "megane")
- Tools
- csi now uses (system-config-directory) to find csirc and falls back to
$HOME/.csirc when needed.
- chicken-install now uses (system-config-directory) to find a user
defined setup.defaults file ; it also uses (system-cache-directory)
for its egg cache directory when the CHICKEN_EGG_CACHE environment
variable is not defined.
- Egg specifications
- Allows "cond-expand" and "error" forms in egg specification files.
- Add "c-object" and "object" properties to link separately compiled
C objects into CHICKEN code.

Changes in 2.2.5 (since 2.2.4):
* Notable improvements
** Greatly improved performance of bidirectional pipes.
The performance of bidirectional pipes, as created using 'open-pipe' or
'open-pipe*' in OPEN_BOTH mode, has been greatly improved. When reading
large blocks of binary data from a bidirectional pipe, the maximum
bandwidth has been increased by a factor of ~10^3 in some cases.
** New 'get-bytevector-some!' I/O primitive.
This new I/O primitive is similar to 'get-bytevector-some' from the
R6RS, except that it writes its data to a user-specified range of
indices in an existing bytevector. As a corollary, it is also now
possible to specify a maximum number of bytes to read. Note that
'get-bytevector-some', and now 'get-bytevector-some!', are unique among
Guile's I/O primitives in their support of efficient binary reads of
potentially large blocks while also allowing for short reads, to avoid
undesired blocking. Now these operations can be performed while also
avoiding heap-allocation.
'get-bytevector-some!' is needed to efficiently implement the new
bidirectional pipes, which are built upon R6RS custom binary
input/output ports.
** get-bytevector-{n!,some,some!} now support suspendable I/O.
Scheme implementations of 'get-bytevector-n!', 'get-bytevector-some',
and 'get-bytevector-some!' have been added to (ice-9 suspendable-ports).
As a result, these I/O operations now support suspendable I/O.
* Compiler improvements
** guild compile: Add -Wshadowed-toplevel.
Top-level definitions that shadow previous top-level definitions from
the same compilation unit will now trigger a compile-time warning, if
-Wshadowed-toplevel is enabled. It is enabled by default.
** guild compile: Add '-x' flag.
Passing "-x EXT" to 'guild compile' will now cause EXT to be recognized
as a valid source file name extension. For example, to compile R6RS
code, you might want to pass "-x .sls" so that files ending in ".sls"
can be found.
* Miscellaneous improvements
** Bootstrap optimization
eval.go and psyntax-pp.go are now built before the rest of the .go files
so that they are processed by a fast macro expander. This saves time
when using parallel builds.
** put-u8 now always writes a single byte, regardless of the port encoding.
Previously, (put-u8 PORT OCTET) worked as expected only when writing to
binary ports, i.e. those with port encoding "ISO-8859-1" a.k.a. Latin-1.
Strictly speaking, this meets the requirements of the R6RS 'put-u8',
which need only support binary ports. However, Guile in fact allows
binary I/O to be performed on any port, and yet 'put-u8' behaved in a
surprising way with other port encodings: it would perform a _textual_
I/O operation, writing the character with Unicode scalar value OCTET.
Now, 'put-u8' always writes a single byte with value OCTET, regardless
of the port encoding.
** Optimize fixnum exact integer square roots.
'exact-integer-sqrt' now avoids heap allocation when applied to a
fixnum. 'sqrt' now avoids heap allocation when applied to a fixnum
that's a perfect square. Fewer heap allocations are now required when
applying 'sqrt' to a square of an exact rational whose numerator or
denominator are fixnums.
** scm_mkstrport: Optimize the POS -> BYTE_POS conversion.
scm_mkstrport now avoids an unnecessary heap allocation and conversion
to UTF-8, when STR is provided and POS is non-zero.
** SRFI-19: Support ~N in string->date.
Support for the ~N escape, which allows fractions of a second to be
parsed, is now supported in SRFI-19 'string->date'.
** SRFI-19: Update the leap second table.
The leap on 1 January 2017 was added to SRFI-19's leap second table.
** stexi->shtml: Add support for @i, @math, @tie and @dots.
stexi->shtml is now able to convert @i, @math, @tie and @dots to HTML.
** Define AT_SYMLINK_NOFOLLOW, AT_NO_AUTOMOUNT, and AT_EMPTY_PATH.
AT_SYMLINK_FOLLOW, AT_NO_AUTOMOUNT, and AT_EMPTY_PATH are now available
from Scheme, if supported on the platform.
** Improvements to the 'time' macro from (ice-9 time).
The 'time' macro now supports expressions that return multiple values.
It has also been rewritten as a hygienic 'syntax-rules' macro.
Previously, it was built using 'define-macro', and was therefore
unhygienic. This is not merely an internal implementation detail, but
is potentially relevant to any user of the 'time' macro, since it could
lead to unintended variable capture and other problems.
** Clarify the documentation for 'nil?'.
See commit b44f505f1571fc9c42e58982f161a9cfc81fb7f4.
** Clarify the manual's "Processes" section.
See commit 8cdd3a0773930ca872a13aada7a1344f03bb382b.
** Avoid 'with-latin1-locale' in binary I/O tests.
See commit 162a031e5f2c64cd23fcf069fb7b5071196f9527.
** Update user-visible copyright years.
* Bug fixes
** Avoid regexp ranges in HTTP inter-protocol exploitation check.
The regular expression used to check for HTTP inter-protocol
exploitation attacks previously used a character range '0-9', whose
meaning depends on the current locale. This has now been fixed.
** Fixes to the SRFI-19 time/date library.
*** TAI-to-UTC conversion leaps at the wrong time.
<https://bugs.gnu.org/21911>
*** time-utc->date shows bogus zone-dependent leap second.
<https://bugs.gnu.org/22034>
*** Manual incorrectly describes Julian Date.
<https://bugs.gnu.org/21902>
*** date->string duff ISO 8601 negative years.
<https://bugs.gnu.org/21903>
*** date->string duff ISO 8601 format for non-4-digit years.
<https://bugs.gnu.org/21904>
*** julian-day->date negative input breakage.
<https://bugs.gnu.org/21906>
*** time-duration screws up negative durations.
<https://bugs.gnu.org/26162>
*** time-difference doesn't detect error of differing time types.
<https://bugs.gnu.org/26163>
** Improve overflow checks in bytevector, string, and I/O operations.
Several numerical computations, performed using primitive C arithmetic
in Guile's core bytevector, string, and I/O operations, have been
rewritten to avoid overflows.
** Fix type inferencing for 'nil?' and 'null?' predicates.
Previously, the compiler would sometimes miscompile certain combinations
of 'nil?' and 'null?' predicates present within the same top-level form.
See <https://bugs.gnu.org/33036>.
** Fix 'atomic-box-compare-and-swap!'.
Previously, 'atomic-box-compare-and-swap!' would sometimes spuriously
fail on architectures based on Load-Linked/Store-Conditional (LL/SC)
synchronication primitives (e.g. ARM, PowerPC, and MIPS) in a way that
was undetectable by the caller. See <https://bugs.gnu.org/32786>.
** Make URI handling locale independent.
Previously, procedures in (web uri) would misbehave in some locales
including sv_SE. See <https://bugs.gnu.org/35785>.
** Strings, i18n: Limit the use of alloca to approximately 8 kilobytes.
Previously, 'string-locale-ci=?', 'string-locale-ci<?',
'string-locale<?', 'string-locale-{downcase,upcase,titlecase}' and
'string-normalize-{nfd,nfc,nfkd,nfkc}' would overflow the C stack when
applied to very large strings.
** Fix documentation of R6RS 'binary-port?' to reflect reality.
Previously, the documentation incorrectly stated that 'binary-port?'
always returns #t. In fact, it returns #t if and only if the port
encoding is "ISO-8859-1". The documentation for 'binary-port?' and
'textual-port?' has been rewritten to reflect the current reality, and
also to leave open the possibility of changing the behavior of these
predicates in a future version of Guile.
** Avoid passing NULL to 'memcpy' and 'memcmp'.
Previously, NULL was sometimes passed to 'memcpy' or 'memcmp' when the
size argument was 0.
** Save and restore errno in the signal handler.
Previously, Guile's synchronous C signal handler failed to save and
restore 'errno', although it might change its value. This could
potentially lead to spurious corruptions of 'errno' within threads
interrupted by signals.
** scm_to_stringn: Avoid passing NULL to c_strcasecmp.
<https://lists.gnu.org/archive/html/guile-user/2019-05/msg00070.html>
** r6rs-ports: Accept 'port-position' values greater than 2^32.
<https://bugs.gnu.org/32161>
** r6rs-ports: 'put-bytevector' accepts 64-bit integers.
Fixed in commit 741c45458da0831a12a4f8d729814bf9f2cb6571.
** Fix R6RS call-with-{input,output}-file to open textual ports.
<https://bugs.gnu.org/32329>
** Update (ice-9 match) to include selected bug fixes from upstream.
*** ice-9/match named match-let is not working

The OpenMP subproject of LLVM contains the components required to build an
executable OpenMP program that are outside the compiler itself.
Here you can find the code for the runtime library against which code compiled
by clang -fopenmp must be linked before it can run.
Changelog:
Changes affecting backwards compatibility
shr is now sign preserving. Use -d:nimOldShiftRight to enable the old behavior globally.
The isLower, isUpper family of procs in strutils/unicode operating on strings have been deprecated since it was unclear what these do. Note that the much more useful procs that operate on char or Rune are not affected.
strutils.editDistance has been deprecated, use editdistance.editDistance or editdistance.editDistanceAscii instead.
The OpenMP parallel iterator `||` now supports any #pragma omp directive and not just #pragma omp parallel for. See OpenMP documentation.
The default annotation is parallel for, if you used OpenMP without annotation the change is transparent, if you used annotations you will have to prefix your previous annotations with parallel for.
Furthermore, an overload with positive stepping is available.
The unchecked pragma was removed, instead use system.UncheckedArray.
The undocumented #? strongSpaces parsing mode has been removed.
The not operator is now always a unary operator, this means that code like assert not isFalse(3) compiles.
getImpl on a var or let symbol will now return the full IdentDefs tree from the symbol declaration instead of just the initializer portion.
Methods are now ordinary “single” methods, only the first parameter is used to select the variant at runtime. For backwards compatibility use the new --multimethods:on switch.
Generic methods are now deprecated; they never worked well.
Compile time checks for integer and float conversions are now stricter. For example, const x = uint32(-1) now gives a compile time error instead of being equivalent to const x = 0xFFFFFFFF'u32.
Using typed as the result type in templates/macros now means “expression with a type”. The old meaning of typed is preserved as void or no result type at all.
A bug allowed macro foo(): int = 123 to compile even though a macro has to return a NimNode. This has been fixed.
With the exception of uint and uint64, conversion to unsigned types are now range checked during runtime.
Macro arguments of type typedesc are now passed to the macro as NimNode like every other type except static. Use typed for a behavior that is identical in new and old Nim. See the RFC Pass typedesc as NimNode to macros for more details.
Breaking changes in the standard library
osproc.execProcess now also takes a workingDir parameter.
std/sha1.secureHash now accepts openArray[char], not string. (Former successful matches should keep working, though former failures will not.)
options.UnpackError is no longer a ref type and inherits from system.Defect instead of system.ValueError.
system.ValueError now inherits from system.CatchableError instead of system.Defect.
The procs parseutils.parseBiggestInt, parseutils.parseInt, parseutils.parseBiggestUInt and parseutils.parseUInt now raise a ValueError when the parsed integer is outside of the valid range. Previously they sometimes raised an OverflowError and sometimes they returned 0.
The procs parseutils.parseBin, parseutils.parseOct and parseutils.parseHex were not clearing their var parameter number and used to push its value to the left when storing the parsed string into it. Now they always set the value of the parameter to 0 before storing the result of the parsing, unless the string to parse is not valid (then the value of number is not changed).
streams.StreamObject now restricts its fields to only raise system.Defect, system.IOError and system.OSError. This change only affects custom stream implementations.
nre’s RegexMatch.{captureBounds,captures}[] no longer return Option or nil/"", respectively. Use the newly added n in p.captures method to check if a group is captured, otherwise you’ll receive an exception.
nre’s RegexMatch.{captureBounds,captures}.toTable no longer accept a default parameter. Instead uncaptured entries are left empty. Use Table.getOrDefault() if you need defaults.
nre’s RegexMatch.captures.{items,toSeq} now returns an Option[string] instead of a string. With the removal of nil strings, this is the only way to indicate a missing match. Inside your loops, instead of capture == "" or capture == nil, use capture.isSome to check if a capture is present, and capture.get to get its value.
nre’s replace() no longer throws ValueError when the replacement string has missing captures. It instead throws KeyError for named captures, and IndexError for unnamed captures. This is consistent with RegexMatch.{captureBounds,captures}[].
splitFile now correctly handles edge cases, see #10047.
isNil is no longer false for undefined in the JavaScript backend: now it’s true for both nil and undefined. Use isNull or isUndefined if you need exact equality: isNil is consistent with ===, isNull and isUndefined with ==.
several deprecated modules were removed: ssl, matchers, httpserver, unsigned, actors, parseurl
two poorly documented and not used modules (subexes, scgi) were moved to graveyard (they are available as Nimble packages)
procs string.add(int) and string.add(float) which implicitly convert ints and floats to string have been deprecated. Use string.addInt(int) and string.addFloat(float) instead.
case object branch transitions via system.reset are deprecated. Compile your code with -d:nimOldCaseObjects for a transition period.
base64 module: The default parameter newLine for the encode procs was changed from "\13\10" to the empty string "".
Breaking changes in the compiler
The compiler now implements the “generic symbol prepass” for when statements in generics, see bug #8603. This means that code like this does not compile anymore:
proc enumToString*(enums: openArray[enum]): string =
# typo: 'e' instead 'enums'
when e.low.ord >= 0 and e.high.ord < 256:
result = newString(enums.len)
else:
result = newString(enums.len * 2)
discard x is now illegal when x is a function symbol.
Implicit imports via --import: module in a config file are now restricted to the main package.
Library additions
There is a new stdlib module std/editdistance as a replacement for the deprecated strutils.editDistance.
There is a new stdlib module std/wordwrap as a replacement for the deprecated strutils.wordwrap.
Added split, splitWhitespace, size, alignLeft, align, strip, repeat procs and iterators to unicode.nim.
Added or for NimNode in macros.
Added system.typeof for more control over how type expressions can be deduced.
Added macros.isInstantiationOf for checking if the proc symbol is instantiation of generic proc symbol.
Added the parameter isSorted for the sequtils.deduplicate proc.
Added os.relativePath.
Added parseopt.remainingArgs.
Added os.getCurrentCompilerExe (implemented as getAppFilename at CT), can be used to retrieve the currently executing compiler.
Added xmltree.toXmlAttributes.
Added std/sums module for fast summation functions.
Added Rusage, getrusage, wait4 to the posix interface.
Added the posix_utils module.
Added system.default.
Added sequtils.items for closure iterators, allows closure iterators to be used by the mapIt, filterIt, allIt, anyIt, etc.
Library changes
The string output of macros.lispRepr proc has been tweaked slightly. The dumpLisp macro in this module now outputs an indented proper Lisp, devoid of commas.
Added macros.signatureHash that returns a stable identifier derived from the signature of a symbol.
In strutils empty strings now no longer match as substrings.
The Complex type is now a generic object and not a tuple anymore.
The ospaths module is now deprecated, use os instead. Note that os is available in a NimScript environment but unsupported operations produce a compile-time error.
The parseopt module now supports a new flag allowWhitespaceAfterColon (default value: true) that can be set to false for better Posix interoperability. (Bug #9619.)
os.joinPath and os.normalizePath handle edge cases like "a/b/../../.." differently.
securehash was moved to lib/deprecated.
The switch -d:useWinAnsi is not supported anymore.
In times module, procs format and parse accept a new optional DateTimeLocale argument for formatting/parsing dates in other languages.
Language additions
Vm support for float32<->int32 and float64<->int64 casts was added.
There is a new pragma block noSideEffect that works like the gcsafe pragma block.
added os.getCurrentProcessId.
User defined pragmas are now allowed in the pragma blocks.
Pragma blocks are no longer eliminated from the typed AST tree to preserve pragmas for further analysis by macros.
Custom pragmas are now supported for var and let symbols.
Tuple unpacking is now supported for constants and for loop variables.
Case object branches can be initialized with a runtime discriminator if possible discriminator values are constrained within a case statement.
Language changes
The standard extension for SCF (source code filters) files was changed from .tmpl to .nimf, it’s more recognizable and allows tools like Github to recognize it as Nim, see #9647. The previous extension will continue to work.
Pragma syntax is now consistent. Previous syntax where type pragmas did not follow the type name is now deprecated. Also pragma before generic parameter list is deprecated to be consistent with how pragmas are used with a proc. See #8514 and #1872 for further details.
Hash sets and tables are initialized by default. The explicit initHashSet, initTable, etc. are not needed anymore.
Tool changes
jsondoc now includes a moduleDescription field with the module description. jsondoc0 shows comments as its own objects as shown in the documentation.
nimpretty: –backup now defaults to off instead of on and the flag was undocumented; use git instead of relying on backup files.
koch now defaults to build the latest stable Nimble version unless you explicitly ask for the latest master version via --latest.
Compiler changes
The deprecated fmod proc is now unavailable on the VM.
A new --outdir option was added.
The compiled JavaScript file for the project produced by executing nim js will no longer be placed in the nimcache directory.
The --hotCodeReloading has been implemented for the native targets. The compiler also provides a new more flexible API for handling the hot code reloading events in the code.
The compiler now supports a --expandMacro:macroNameHere switch for easy introspection into what a macro expands into.
The -d:release switch now does not disable runtime checks anymore. For a release build that also disables runtime checks use -d:release -d:danger or simply -d:danger.

Some grammar cleanup
Built-in Python modules are built from extracted Python sources and
therefere bound to that specific Python version. For example, trying to
build a module from Python 2.7.16 against an installed Python 2.7.13 is
likely to cause errors.
This commit makes built-in Python modules depend on the full current
Python version.
What’s New in Libc++ 8.0.0?
API Changes
Building libc++ for Mac OSX 10.6 is not supported anymore.
Starting with LLVM 8.0.0, users that wish to link together translation units built with different versions of libc++’s headers into the same final linked image MUST define the _LIBCPP_HIDE_FROM_ABI_PER_TU macro to 1 when building those translation units. Not defining _LIBCPP_HIDE_FROM_ABI_PER_TU to 1 and linking translation units built with different versions of libc++’s headers together may lead to ODR violations and ABI issues. On the flipside, code size improvements should be expected for everyone not defining the macro.
Starting with LLVM 8.0.0, std::dynarray has been removed from the library. std::dynarray was a feature proposed for C++14 that was pulled from the Standard at the last minute and was never standardized. Since there are no plans to standardize this facility it is being removed.
Starting with LLVM 8.0.0, std::bad_array_length has been removed from the library. std::bad_array_length was a feature proposed for C++14 alongside std::dynarray, but it never actually made it into the C++ Standard. There are no plans to standardize this feature at this time. Formally speaking, this removal constitutes an ABI break because the symbols were shipped in the shared library. However, on macOS systems, the feature was not usable because it was hidden behind availability annotations. We do not expect any actual breakage to happen from this change.
Clang Tools 8.0.0:
Improvements to clangd
clangd now adds namespace qualifiers in code completion, for example, if you type “vec”, the list of completions will include “std::vector”.
When a global index is available, clangd will use it to augment the results of “go to definition” and “find references” queries. Global index also enables global code completion, which suggests symbols that are not imported in the current file and automatically inserts the missing #include directives.
clangd stores the symbol index on disk in a new compact binary serialization format. It is 10x more compact than YAML and 40% more compact than gzipped YAML.
clangd has a new efficient symbol index suitable for complex and fuzzy queries and large code bases (e.g., LLVM, Chromium). This index is used for code completion, go to definition, and cross-references. The architecture of the index allows for complex and fuzzy retrieval criteria and sophisticated scoring.
clangd has a new LSP extension that communicates information about activity on clangd’s per-file worker thread. This information can be displayed to users to let them know that the language server is busy with something. For example, in clangd, building the AST blocks many other operations.
clangd has a new LSP extension that allows the client to supply the compilation commands over LSP, instead of finding compile_commands.json on disk.
clangd has a new LSP extension that allows the client to request fixes to be sent together with diagnostics, instead of asynchronously.
clangd has a new LSP extension that allows the client to resolve a symbol in a light-weight manner, without retrieving further information (like definition location, which may require consulting an index).
Improvements to clang-query
A new command line parameter --preload was added to run commands from a file and then start the interactive interpreter.
The command q can was added as an alias for quit to exit the clang-query interpreter.
It is now possible to bind to named values (the result of let expressions).
It is now possible to write comments in clang-query code. This is primarily useful when using script-mode. Comments are all content following the # character on a line.
The new set print-matcher true command now causes clang-query to print the evaluated matcher together with the resulting bindings.
A new output mode detailed-ast was added to clang-query. The existing dump output mode is now a deprecated alias for detailed-ast
Output modes can now be enabled or disabled non-exclusively.
Improvements to clang-tidy
New abseil-duration-comparison check.
Checks for comparisons which should be done in the absl::Duration domain instead of the float of integer domains.
New abseil-duration-division check.
Checks for uses of absl::Duration division that is done in a floating-point context, and recommends the use of a function that returns a floating-point value.
New abseil-duration-factory-float check.
Checks for cases where the floating-point overloads of various absl::Duration factory functions are called when the more-efficient integer versions could be used instead.
New abseil-duration-factory-scale check.
Checks for cases where arguments to absl::Duration factory functions are scaled internally and could be changed to a different factory function.
New abseil-duration-subtraction check.
Checks for cases where subtraction should be performed in the absl::Duration domain.
New abseil-faster-strsplit-delimiter check.
Finds instances of absl::StrSplit() or absl::MaxSplits() where the delimiter is a single character string literal and replaces with a character.
New abseil-no-internal-dependencies check.
Gives a warning if code using Abseil depends on internal details.
New abseil-no-namespace check.
Ensures code does not open namespace absl as that violates Abseil’s compatibility guidelines.
New abseil-redundant-strcat-calls check.
Suggests removal of unnecessary calls to absl::StrCat when the result is being passed to another absl::StrCat or absl::StrAppend.
New abseil-str-cat-append check.
Flags uses of absl::StrCat() to append to a std::string. Suggests absl::StrAppend() should be used instead.
New abseil-upgrade-duration-conversions check.
Finds calls to absl::Duration arithmetic operators and factories whose argument needs an explicit cast to continue compiling after upcoming API changes.
New bugprone-too-small-loop-variable check.
Detects those for loops that have a loop variable with a “too small” type which means this type can’t represent all values which are part of the iteration range.
New cppcoreguidelines-macro-usage check.
Finds macro usage that is considered problematic because better language constructs exist for the task.
New google-objc-function-naming check.
Checks that function names in function declarations comply with the naming conventions described in the Google Objective-C Style Guide.
New misc-non-private-member-variables-in-classes check.
Finds classes that not only contain the data (non-static member variables), but also have logic (non-static member functions), and diagnoses all member variables that have any other scope other than private.
New modernize-avoid-c-arrays check.
Finds C-style array types and recommend to use std::array<> / std::vector<>.
New modernize-concat-nested-namespaces check.
Checks for uses of nested namespaces in the form of namespace a { namespace b { ... }} and offers change to syntax introduced in C++17 standard: namespace a::b { ... }.
New modernize-deprecated-ios-base-aliases check.
Detects usage of the deprecated member types of std::ios_base and replaces those that have a non-deprecated equivalent.
New modernize-use-nodiscard check.
Adds [[nodiscard]] attributes (introduced in C++17) to member functions to highlight at compile time which return values should not be ignored.
New readability-const-return-type check.
Checks for functions with a const-qualified return type and recommends removal of the const keyword.
New readability-isolate-decl check.
Detects local variable declarations declaring more than one variable and tries to refactor the code to one statement per declaration.
New readability-magic-numbers check.
Detects usage of magic numbers, numbers that are used as literals instead of introduced via constants or symbols.
New readability-redundant-preprocessor check.
Finds potentially redundant preprocessor directives.
New readability-uppercase-literal-suffix check.
Detects when the integral literal or floating point literal has non-uppercase suffix, and suggests to make the suffix uppercase. The list of destination suffixes can be optionally provided.
New alias cert-dcl16-c to readability-uppercase-literal-suffix added.
New alias cppcoreguidelines-avoid-c-arrays to modernize-avoid-c-arrays added.
New alias cppcoreguidelines-non-private-member-variables-in-classes to misc-non-private-member-variables-in-classes added.
New alias hicpp-avoid-c-arrays to modernize-avoid-c-arrays added.
New alias hicpp-uppercase-literal-suffix to readability-uppercase-literal-suffix added.
The cppcoreguidelines-narrowing-conversions check now detects more narrowing conversions: - integer to narrower signed integer (this is compiler implementation defined), - integer - floating point narrowing conversions, - floating point - integer narrowing conversions, - constants with narrowing conversions (even in ternary operator).
The objc-property-declaration check now ignores the Acronyms and IncludeDefaultAcronyms options.
The readability-redundant-smartptr-get check does not warn about calls inside macros anymore by default.
The readability-uppercase-literal-suffix check does not warn about literal suffixes inside macros anymore by default.
Clang 8.0.0:
Major New Features
* Clang supports use of a profile remapping file, which permits profile data captured for one version of a program to be applied when building another version where symbols have changed (for example, due to renaming a class or namespace). See the UsersManual for details.
* Clang has new options to initialize automatic variables with a pattern. The default is still that automatic variables are uninitialized. This isn’t meant to change the semantics of C and C++. Rather, it’s meant to be a last resort when programmers inadvertently have some undefined behavior in their code. These options aim to make undefined behavior hurt less, which security-minded people will be very happy about.
* Improvements to Clang’s diagnostics
Non-comprehensive list of changes in this release
* The experimental feature Pretokenized Headers (PTH) was removed in its entirely from Clang. The feature did not properly work with about 1/3 of the possible tokens available and was unmaintained.
* The internals of libc++ include directory detection on MacOS have changed. Instead of running a search based on the -resource-dir flag, the search is now based on the path of the compiler in the filesystem. The default behaviour should not change. However, if you override -resource-dir manually and rely on the old behaviour you will need to add appropriate compiler flags for finding the corresponding libc++ include directory.
* The integrated assembler is used now by default for all MIPS targets.
* Improved support for MIPS N32 ABI and MIPS R6 target triples.
* Clang now includes builtin functions for bitwise rotation of common value sizes, such as: __builtin_rotateleft32
* Improved optimization for the corresponding MSVC compatibility builtins such as _rotl().
8.0.0:
Non-comprehensive list of changes in this release
* The llvm-cov tool can now export lcov trace files using the -format=lcov option of the export command.
* The add_llvm_loadable_module CMake macro has been removed. The add_llvm_library macro with the MODULE argument now provides the same functionality. See Writing an LLVM Pass.
* For MinGW, references to data variables that might need to be imported from a dll are accessed via a stub, to allow the linker to convert it to a dllimport if needed.
* Added support for labels as offsets in .reloc directive.
* Support for precise identification of X86 instructions with memory operands, by using debug information. This supports profile-driven cache prefetching. It is enabled with the -x86-discriminate-memops LLVM Flag.
* Support for profile-driven software cache prefetching on X86. This is part of a larger system, consisting of: an offline cache prefetches recommender, AutoFDO tooling, and LLVM. In this system, a binary compiled with -x86-discriminate-memops is run under the observation of the recommender. The recommender identifies certain memory access instructions by their binary file address, and recommends a prefetch of a specific type (NTA, T0, etc) be performed at a specified fixed offset from such an instruction’s memory operand. Next, this information needs to be converted to the AutoFDO syntax and the resulting profile may be passed back to the compiler with the LLVM flag -prefetch-hints-file, together with the exact same set of compilation parameters used for the original binary. More information is available in the RFC.
* Windows support for libFuzzer (x86_64).

GCC 8.3
This is the list of problem reports (PRs) from GCC's bug tracking system that are known to be fixed in the 8.3 release. This list might not be complete (that is, it is possible that some PRs that have been fixed are not listed here).
Windows
https://gcc.gnu.org/bugzilla/buglist.cgi?bug_status=RESOLVED&resolution=FIXED&target_milestone=8.3
A C++ Microsoft ABI bitfield layout bug, PR87137 has been fixed. A non-field declaration could cause the current bitfield allocation unit to be completed, incorrectly placing a following bitfield into a new allocation unit. The Microsoft ABI is selected for:
Mingw targets
PowerPC, IA-32 or x86-64 targets when the -mms-bitfields option is specified, or __attribute__((ms_struct)) is used
SuperH targets when the -mhitachi option is specified, or __attribute__((renesas)) is used
GCC 8 introduced additional cases of this defect, but rather than resolve only those regressions, we decided to resolve all the cases of this defect in single change.
This release includes fixes to the compiler, the linker, the go command,
the runtime, and the os package.
Same as for go111, remove the pkg/bootstrap tree from the package.
This release includes fixes to the compiler, the linker, the go command, the
runtime, and the os package.
While here, remove pkg/bootstrap from the package, as it is only used
for bootstrapping.
configure forced to pass `-g' to CFLAGS and did not strip resulting binaries and
libraries. Pass `--disable-debug-symbols' and `--enable-strip' to respectively
address that.
Fix PR pkg/54228 reported by matt farnsworth.
While here, avoid to pass `-Wl,-z,wxneeded' to LDFLAGS on NetBSD.
Main changes:
* some quality-of-life bug fixes,
* many improvements to the documentation,
* a critical bug fix related to primitive projections and native_compute,
* several additional Coq libraries shipped with the Windows installer.
3.3.3:
As before, decomplation bugs fixed. The focus has primarily been on Python 3.7. But with this release, releases will be put on hold,as a better control-flow detection is worked on . Tis has been needed for a while, and is long overdue. It will probably also take a while to get done as good as what we have now.
However this work will be done in a new project decompyle3. In contrast to uncompyle6 the code wil be written assuming a modern Python 3, e.g. 3.7. It is originally intended to decompile Python version 3.7 and greater.
A number of Python 3.7+ chained comparisons were fixed
Revise Python 3.6ish format string handling
Go over operator precedence, e.g. for AST IfExp

This supports packages that require a large number of go-based dependencies,
treating them as additional distfiles and built inline as part of the package
build. The print-go-deps target is helpful to generate the list of GO_DEPS
required for each package by parsing the Gopkg.lock file in the extracted
sources.

release-python-3.3.2
As before, lots of decomplation bugs fixed. The focus has primarily
been on Python 3.6. We can now parse the entire 3.6.8 Python library
and verify that without an error. The same is true for 3.5.8. A number
of the bugs fixed though are not contained to these versions. In fact
some span back as far as 2.x
But as before, many more remain in the 3.7 and 3.8 range which will
get addressed in future releases
Pypy 3.6 support was started. Pypy 3.x detection fixed (via xdis)
Changelog:
New Japanese Era Name: Reiwa (JDK-8205432)
core-libs/java.time
An instance representing the new Reiwa era has been added to this update. Unlike other eras, there is no public field for this era. It can be obtained by calling JapaneseEra.of(3) or JapaneseEra.valueOf("Reiwa"). JDK 13 and later will have a new public field to represent this era.
The placeholder name, "NewEra", for the Japanese era that started from May 1st, 2019 has been replaced with the new official name. Applications that relied on the placeholder name (see JDK-8202088) to obtain the new era singleton (JapaneseEra.valueOf("NewEra")) will no longer work.
Added GlobalSign R6 Root Certificate (JDK-8216577)
security-libs/java.security
The following root certificate has been added to the cacerts truststore:
+ GlobalSign
+ globalsignrootcar6
DN: CN=GlobalSign, O=GlobalSign, OU=GlobalSign Root CA - R6
Because python won't even try to build it.
You only see nis_failed.so if there is an error building it, when
it wanted to build it, and that should be fixed accordingly.
In a nutshell, if the yp headers are installed, python will build
the nis module, otherwise it won't.
On netbsd systems at least, if you have the yp headers installed and
subsequently re-install over the top with MKYP=no you get into the state
where the headers are installed, but the functions are no longer in libc.
This is an error with *your* system - either rebuild with MKYP=yes OR
remove the yp headers from include/rpc and include/rpcsvc.
Follow on fix for PR pkg/53673.
release-3.3.1
Lots of decomplation bugs, especially in the 3.x series fixed. Don't worry though, many more remain.
* Add annotation return values in 3.6+
* Fix 3.6+ lambda parameter handling decompilation
* Fix 3.7+ chained comparision decompilation
* split out semantic-action customization into more separate files
* Add 3.8 try/else
* Fix 2.7 generator decompilation
* Fix some parser failures fixes in 3.4+ using test_pyenvlib
* Add more run tests
Highlights from erlang 21.2 to 21.3:
Kernel:
The standard logger handler, logger_std_h, now has a new internal
feature for log rotation. For full information see the documentation.
SSL:
The Reason part of the error return from the functions connect and
handshake has a better and documented format. This is a potential
incompatibility. See the documentation.
Refactoring of state handling has improved the TLS application data
throughput and reduced CPU overhead
Code optimizations has reduced CPU load for encryption/decryption,
especially for Erlang's distribution protocol over TLS
Now supports active N
Erl_interface:
Support for plugin of a user supplied socket implementation has been added.
OTP:
The HTML reference documentation now shows the OTP version where
modules and functions were first introduced. Versions of OTP older than R13B04 is not shown in the reference
documentation
NAME
perldelta - what is new for perl v5.28.2
DESCRIPTION
This document describes differences between the 5.28.1 release and the 5.28.2 release.
If you are upgrading from an earlier release such as 5.28.0, first read perl5281delta, which describes
differences between 5.28.0 and 5.28.1.
Incompatible Changes
Any set of digits in the Common script are legal in a script run of another script
There are several sets of digits in the Common script. "[0-9]" is the most familiar. But there are also
"[\x{FF10}-\x{FF19}]" (FULLWIDTH DIGIT ZERO - FULLWIDTH DIGIT NINE), and several sets for use in
mathematical notation, such as the MATHEMATICAL DOUBLE-STRUCK DIGITs. Any of these sets should be able to
appear in script runs of, say, Greek. But the previous design overlooked all but the ASCII digits "[0-9]",
so the design was flawed. This has been fixed, so is both a bug fix and an incompatibility.
All digits in a run still have to come from the same set of ten digits.
Modules and Pragmata
Updated Modules and Pragmata
o Module::CoreList has been upgraded from version 5.20181129_28 to 5.20190419.
o PerlIO::scalar has been upgraded from version 0.29 to 0.30.
o Storable has been upgraded from version 3.08 to 3.08_01.
Platform Support
Platform-Specific Notes
Windows
The Windows Server 2003 SP1 Platform SDK build, with its early x64 compiler and tools, was accidentally
broken in Perl 5.27.9. This has now been fixed.
Mac OS X
Perl's build and testing process on Mac OS X for "-Duseshrplib" builds is now compatible with Mac OS X
System Integrity Protection (SIP).
SIP prevents binaries in /bin (and a few other places) being passed the "DYLD_LIBRARY_PATH" environment
variable. For our purposes this prevents "DYLD_LIBRARY_PATH" from being passed to the shell, which
prevents that variable being passed to the testing or build process, so running "perl" couldn't find
libperl.dylib.
To work around that, the initial build of the perl executable expects to find libperl.dylib in the build
directory, and the library path is then adjusted during installation to point to the installed library.
Selected Bug Fixes
o If an in-place edit is still in progress during global destruction and the process exit code (as stored
in $?) is zero, perl will now treat the in-place edit as successful, replacing the input file with any
output produced.
This allows code like:
perl -i -ne 'print "Foo"; last'
to replace the input file, while code like:
perl -i -ne 'print "Foo"; die'
will not.
o A regression in Perl 5.28 caused the following code to fail
close(STDIN); open(CHILD, "|wc -l")'
because the child's stdin would be closed on exec. This has now been fixed.
o "pack "u", "invalid uuencoding"" now properly NUL terminates the zero-length SV produced.
o Failing to compile a format now aborts compilation. Like other errors in sub-parses this could leave
the parser in a strange state, possibly crashing perl if compilation continued.
o See "Any set of digits in the Common script are legal in a script run of another script".
Update ruby26{,-base} to 2.6.3. Here is release announce:
Ruby 2.6.3 Released
Posted by naruse on 17 Apr 2019
Ruby 2.6.3 has been released.
This release adds support for New Japanese Era “令和” (Reiwa). It updates
the Unicode version to 12.1 beta (#15195), and updates date library (#15742).
This release also includes some bug fixes. See details commit logs.
release-3.3.0
First cut at Python 3.8 (many bugs remain)
Reinstate -c | --compile (compile before disassembly) option
The usual smattering of bug and doc fixes
go1.12.2 (released 2019/04/05) includes fixes to the compiler, the go command,
the runtime, and the doc, net, net/http/httputil, and os packages. See the Go
1.12.2 milestone on our issue tracker for details.
go1.12.3 (released 2019/04/08) was accidentally released without its intended
fix. It is identical to go1.12.2, except for its version number. The intended
fix is in go1.12.4.
go1.12.4 (released 2019/04/11) fixes an issue where using the prebuilt binary
releases on older versions of GNU/Linux led to failures when linking programs
that used cgo. Only Linux users who hit this issue need to update.
go1.11.7 (released 2019/04/05) includes fixes to the runtime and the net
packages. See the Go 1.11.7 milestone on our issue tracker for details.
go1.11.8 (released 2019/04/08) was accidentally released without its intended
fix. It is identical to go1.11.7, except for its version number. The intended
fix is in go1.11.9.
go1.11.9 (released 2019/04/11) fixes an issue where using the prebuilt binary
releases on older versions of GNU/Linux led to failures when linking programs
that used cgo. Only Linux users who hit this issue need to update.
Changelog:
Changes from 4.2.1 to 5.0.0
---------------------------
1. Support for the POSIX standard %a and %A printf formats has been added.
2. The test infrastructure has been greatly improved, simplifying the
contents of test/Makefile.am and making it possible to generate
pc/Makefile.tst from test/Makefile.in.
3. The regex routines have been replaced with those from GNULIB, allowing
me to stop carrying forward decades of changes against the original
ones from GLIBC.
4. Infrastructure upgrades: Bison 3.3, Automake 1.16.1, Gettext 0.19.8.1,
makeinfo 6.5.
5. The undocumented configure option and code that enabled the use of
non-English "letters" in identifiers is now gone.
6. The `--with-whiny-user-strftime' configuration option is now gone.
7. The code now makes some stronger assumptions about a C99 environment.
8. PROCINFO["platform"] yields a string indicating the platform for
which gawk was compiled.
9. Writing to elements of SYMTAB that are not variable names now
causes a fatal error. THIS CHANGES BEHAVIOR.
10. Comment handling in the pretty-printer has been reworked almost completely
from scratch. As a result, comments in many corner cases that were
previously lost are now included in the formatted output.
11. Namespaces have been implemented! See the manual. One consequence of this
is that files included with -i, read with -f, and command line program
segments must all be self-contained syntactic units. E.g., you can no
longer do something like this:
gawk -e 'BEGIN {' -e 'print "hello" }'
12. Gawk now uses the locale settings for ignoring case in single byte
locales, instead of hardwiring in Latin-1.
13. A number of bugs, some of them quite significant, have been fixed.
See the ChangeLog for details.
openbsd requires mapping the stack with MAP_STACK. binaries not doing this
will not run. patch taken from openbsd ports, via sjmulder.
I modified it to use GOOS_openbsd, because other OSes are not provided
an implementation of sysMarkStack.
Bump PKGREVISION.
* vulnerabilities of rubygems are already fixed in 2.4.5nb1.
Ruby 2.4.6 Released 1 Apr 2019
Ruby 2.4.6 has been released.
This release includes about 20 bug fixes after the previous release, and also
includes several security fixes. Please check the topics below for details.
* Multiple vulnerabilities in RubyGems
See the commit log for details.
After this release, we will end the normal maintenance phase of Ruby 2.4, and
start the security maintenance phase of it. This means that after the release
of 2.4.6 we will never backport any bug fixes to 2.4 except security fixes.
The term of the security maintenance phase is scheduled for 1 year. By the
end of this term, official support of Ruby 2.4 will be over. Therefore, we
recommend that you start planning to upgrade to Ruby 2.6 or 2.5.
As discussed on pkgsrc-users, rust does not work on any NetBSD before
8, for any architecture. Omit NetBSD 1 from the broken list, so that
this doesn't match NetBSD 10.
As discussed on pkgsrc-users, mark rust as BROKEN_ON for NetBSD 7
i386. The bootstrap is built for 8, apparently because it doens't
build on 7. This is BROKEN_ON not NOT_FOR because it does make sense
to want rust on 7 -- it just won't build.
(Probably this should be expanded to all arches and all versions < 8.)
Match the logic used by setup.py: it looks for two headers in the default
include path. This helps newer glibc linux.
Omit PLIST.dll on python3* because it doesn't appear in the PLIST.
Make PLIST.dll true on all non-IRIX.
tested: NetBSD-current, FreeBSD 11.2, Ubuntu 18.10, CentOS 6.9, Source Mage
From Dr. Thomas Orgis, myself, and with pointers to a change from leot.

Fix handling of negative maxsize which should have been treated as zero. Fix errors in toggling the “full” status flag. Fix misordering of links when errors are encountered. Sync-up the C code and pure Python code for the space saving path in functions with a single positional argument.

bpo-35643: Fixed a SyntaxWarning: invalid escape sequence in Modules/_sha3/cleanup.py. Patch by Mickaël Schoentgen.
bpo-35615: weakref: Fix a RuntimeError when copying a WeakKeyDictionary or a WeakValueDictionary, due to some keys or values disappearing while iterating.
bpo-28503: The crypt module now internally uses the crypt_r() library function instead of crypt() when available.
bpo-35121: Don’t set cookie for a request when the request path is a prefix match of the cookie’s path attribute but doesn’t end with “/”. Patch by Karthikeyan Singaravelan.
bpo-35585: Speed-up building enums by value, e.g. http.HTTPStatus(200).
bpo-21478: Calls to a child function created with unittest.mock.create_autospec() should propagate to the parent. Patch by Karthikeyan Singaravelan.
bpo-35513: TextTestRunner of unittest.runner now uses time.perf_counter() rather than time.time() to measure the execution time of a test: time.time() can go backwards, whereas time.perf_counter() is monotonic.
bpo-35502: Fixed reference leaks in xml.etree.ElementTree.TreeBuilder in case of unfinished building of the tree (in particular when an error was raised during parsing XML).
bpo-31446: Copy command line that was passed to CreateProcessW since this function can change the content of the input buffer.
bpo-20239: Allow repeated assignment deletion of unittest.mock.Mock attributes. Patch by Pablo Galindo.
bpo-17185: Set __signature__ on mock for inspect to get signature. Patch by Karthikeyan Singaravelan.
bpo-10496: check_environ() of distutils.utils now catches KeyError on calling pwd.getpwuid(): don’t create the HOME environment variable in this case.
bpo-35066: Previously, calling the strftime() method on a datetime object with a trailing ‘%’ in the format string would result in an exception. However, this only occured when the datetime C module was being used; the python implementation did not match this behavior. Datetime is now PEP-399 compliant, and will not throw an exception on a trailing ‘%’.
bpo-24746: Avoid stripping trailing whitespace in doctest fancy diff. Orignial patch by R. David Murray & Jairo Trad. Enhanced by Sanyam Khurana.
bpo-35198: Fix C++ extension compilation on AIX
bpo-28441: On Cygwin and MinGW, ensure that sys.executable always includes the full filename in the path, including the .exe suffix (unless it is a symbolic link).
bpo-34572: Fix C implementation of pickle.loads to use importlib’s locking mechanisms, and thereby avoid using partially-loaded modules. Patch by Tim Burgess.
bpo-33687: Fix the call to os.chmod() for uu.decode() if a mode is given or decoded. Patch by Timo Furrer.
bpo-32146: Document the interaction between frozen executables and the spawn and forkserver start methods in multiprocessing.

Changes since previous version (2.2.0):
pkgsrc: use the included Makefile.cmdline to build duktape, rather
than custom command in pkgsrc Makefile. Don't assume ${CC} is gcc
while doing so
XXX - it looks like the ABI has changed (silently) from 2.2.0 without
a corresponding libtool version bump from upstream. caveat buildor
2.3.0 (2018-08-04)
+ When C++ exception support is enabled use a separate
duk_fatal_exception (inherits from std::runtime_error) to propagate
fatal errors (uncaught errors, assertions) out of Duktape when using
the default fatal error handler (GH-1915)
+ Update UnicodeData.txt and SpecialCasing.txt used for building
internal Unicode control data to Unicode version 10.0.0 (GH-1851)
+ Add support for Symbol.hasInstance (@@hasInstance) check for
'instanceof' operator and duk_instanceof() API call; also add
Symbol.hasInstance and Function.prototype[@@hasInstance] (GH-1821)
+ Add support for Symbol.toStringTag (@@toStringTag) in
Object.prototype.toString() (GH-1822)
+ Add support for Symbol.isConcatSpreadable (@@isConcatSpreadable) in
Array.prototype.concat() (GH-1823)
+ Add support for Symbol.toPrimitive (@@toPrimitive) in ToPrimitive()
internal algorithm and duk_to_primitive() API call (GH-1825)
+ Invoke Proxy 'has' trap in Array.prototype.concat() when inspecting
the elements of the Proxy target (GH-1823)
+ Remove DUK_USE_NONSTD_ARRAY_CONCAT_TRAILER because the underlying
ES5.1 specification "bug" was fixed in ES2015 (GH-1823)
+ Remove DUK_USE_NONSTD_ARRAY_MAP_TRAILER because ES5.0/ES5.1 behavior
actually did match the "non-standard" behavior provided by the option
(GH-1823)
+ Add duk_random() to allow C code access to the same random number
source as ECMAScript code (GH-1815)
+ Add duk_push_new_target() to allow C code to access new.target; at
present this is for completeness because without actual class support
it's only useful to detect constructor calls which can already be done
using duk_is_constructor_call() (GH-1745)
+ Add experimental API call variants for plain C literals, for example
duk_push_literal(ctx, "key") and duk_get_prop_literal(ctx,
"propname"), which allow e.g. better performance; calls added:
duk_push_literal(), duk_get_prop_literal(), duk_put_prop_literal(),
duk_has_prop_literal(), duk_del_prop_literal(),
duk_get_global_literal(), duk_put_global_literal() (GH-1805)
+ Add duk_get_global_heapptr() and duk_put_global_heapptr() for
completeness (GH-1805)
+ Automatically pin strings accessed using the C literal API call
variants such as duk_get_prop_literal(ctx, "propname") between
mark-and-sweep rounds to facilitate literal caching and to reduce
string table traffic; this behavior can be disabled by disabling
DUK_USE_LITCACHE_SIZE in configure.py (GH-1813)
+ Add a lookup cache for C literals to speed up string table lookups
when using API call variants such as duk_get_prop_literal(ctx,
"propname"); the cache relies on literals being pinned between
mark-and-sweep rounds, and can be disabled by disabling
DUK_USE_LITCACHE_SIZE in configure.py (GH-1813)
+ ES2015 Number constructor properties: EPSILON, MIN_SAFE_INTEGER,
MAX_SAFE_INTEGER, isFinite(), isInteger(), isNaN(), isSafeInteger(),
parseInt(), parseFloat() (GH-1756, GH-1761)
+ Assume only natural alignment (DUK_USE_ALIGN_BY=8) on all platforms
to minimize compiler assumptions regarding unaligned accesses (which
can be an issue even on x86); applications working with a low memory
target may want to force DUK_USE_ALIGN_BY in configuration (GH-1783,
GH-1784)
+ Base64 decoder is now more lenient for padding: accepts missing
padding ('Zm'), partial padding ('Zm='), standard padding ('Zm=='),
and extra padding ('Zm===' etc), also for concatenated documents
('Zm===Zm' decodes to 'ff' for example) (GH-1789)
+ Base64 encoder and decoder performance improvements for both fast
path and slow path variants (GH-1789)
+ Make base64 support optional and drop it from lowmem base
configuration; define DUK_USE_BASE64_SUPPORT to enable it (GH-1789)
+ Make hex support optional and drop it from lowmem base
configuration; define DUK_USE_BASE64_SUPPORT to enable it (GH-1789)
+ Add C++ name mangling wrappers (extern "C") for extras (GH-1780,
GH-1782)
+ Add a duk_uint64_t to duk_hbuffer_fixed forced alignment union trick
just in case double and uint64_t alignment requirements differ
(GH-1799)
+ Add a CBOR encoder/decoder as an extra (GH-1781, GH-1800, GH-1801)
+ Add a minimal ES2015 Promise polyfill into the distribution
(GH-1865)
+ Include <exception> only when compiling as C++ with C++ exception
support enabled (GH-1838, GH-1839)
+ Allow undefined timeout in eventloop example setTimeout() and
setInterval() bindings, minor cleanups and improvements (GH-1866,
GH-1879, GH-1884)
+ Revise Number.prototype.toFixed() 'this' binding and fractionDigits
argument validation order to match ES2015 where the 'this' binding is
validated first (GH-1887)
+ Add Makefile.jsoncbor to the distributable (GH-1885)
+ Makefile.sharedlibrary portability improvements (GH-1922, GH-1923)
+ Change spelling from ECMAScript to ECMAScript throughout the
internal source code; as far as external behavior is concerned this
only affects a few debug prints (GH-1894)
+ Fix NULL pointer dereference in error augmentation when
DUK_USE_TRACEBACKS was disabled (GH-1909)
+ Fix potential dangling pointer use in Duktape thread termination
handling; the dangling pointer could cause unsafe memory behavior
(GH-1845, GH-1868)
+ Fix performance.now() property attributes to 'wec' (earlier 'wc')
(GH-1821)
+ Fix debugger StepOver behavior when a tailcall happens in a nested
function (not the function where stepping started from) (GH-1786,
GH-1787)
+ Fix trailing single line comment handling for Function constructor;
new Function('return "foo" //') previously failed with SyntaxError
(GH-1757)
+ Fix some lexer bugs related to parsing in RegExp mode (interpret
leading '/' as part of a RegExp) or not (interpret '/' as division)
(GH-1779)
+ Fix DUK_BOOL_{MIN,MAX} defines for unsigned duk_bool_t (GH-1769)
+ Fix 'defined but not used' warning for Windows (GH-1775)
+ Fix potential uninitialized data use when Windows Date provider
FileTimeToSystemTime() or FileTimeToLocalFileTime() failed (GH-1953)
+ Fix some Clang warnings by avoiding undefined behavior by default,
define DUK_USE_ALLOW_UNDEFINED_BEHAVIOR to reduce the explicit
undefined behavior checks for better footprint/performance (GH-1777,
GH-1795, GH-1796, GH-1797, GH-1798)
+ Fix some compilation warnings triggered when DUK_NORETURN is not
defined; the internal DUK_WO_NORETURN() is used to include unreachable
dummy statements when the noreturn attribute is not available, e.g.
DUK_WO_NORETURN(return 0;); (GH-1790)
+ Fix a few casts in duk_trans_socket_windows.c to avoid errors in a
C++ build (GH-1773)
+ Fix harmless -Wcast-align warnings on armhf (GH-1793)
+ Various compiler warning fixes (GH-1788, GH-1932, GH-1924, GH-1950,
GH-1951, etc)
+ Add automatic workaround for union aliasing issues with FreeBSD +
-m32 + Clang prior to 5.0; the aliasing issues cause packed duk_tval
to work incorrectly (see
https://github.com/svaarala/duktape/blob/master/misc/clang_aliasing.c),
and the workaround is to use unpacked duk_tval prior to Clang 5.0
(GH-1764)
2.2.1 (2018-04-26)
+ Fix trailing single line comment handling for Function constructor;
new Function('return "foo" //') previously failed with SyntaxError
(GH-1757)
+ Fix DUK_BOOL_{MIN,MAX} defines for unsigned duk_bool_t (GH-1769)
+ Fix debugger StepOver behavior when a tailcall happens in a nested
function (not the function where stepping started from) (GH-1786,
GH-1787)
+ Fix potential dangling pointer use in Duktape thread termination
handling; the dangling pointer could cause unsafe memory behavior
(GH-1845, GH-1868)
