Wed Feb 1 20:18:59 UTC 2023 - Jeff Kowalczyk <jkowalczyk@suse.com>
- go1.20 (released 2023-02-01) is a major release of Go.
go1.20.x minor releases will be provided through February 2024.
https://github.com/golang/go/wiki/Go-Release-Cycle
go1.20 arrives six months after go1.19. Most of its changes are
in the implementation of the toolchain, runtime, and libraries.
As always, the release maintains the Go 1 promise of
compatibility. We expect almost all Go programs to continue to
compile and run as before.
Refs boo#1206346 go1.20 release tracking
Refs jsc#PED-1962
* Go 1.20 includes four changes to the language
* Language change: Go 1.17 added conversions from slice to an
array pointer. Go 1.20 extends this to allow conversions from a
slice to an array
* Language change: The unsafe package defines three new functions
SliceData, String, and StringData. Along with Go 1.17's Slice,
these functions now provide the complete ability to construct
and deconstruct slice and string values, without depending on
their exact representation.
* Language change: The specification now defines that struct
values are compared one field at a time, considering fields in
the order they appear in the struct type definition, and
stopping at the first mismatch. The specification could
previously have been read as if all fields needed to be
compared beyond the first mismatch. Similarly, the
specification now defines that array values are compared one
element at a time, in increasing index order. In both cases,
the difference affects whether certain comparisons must
panic. Existing programs are unchanged: the new spec wording
describes what the implementations have always done.
* Language change: Comparable types (such as ordinary interfaces)
may now satisfy comparable constraints, even if the type
arguments are not strictly comparable (comparison may panic at
runtime). This makes it possible to instantiate a type
parameter constrained by comparable (e.g., a type parameter for
a user-defined generic map key) with a non-strictly comparable
type argument such as an interface type, or a composite type
containing an interface type.
* go command: The directory $GOROOT/pkg no longer stores
pre-compiled package archives for the standard library: go
install no longer writes them, the go build no longer checks
for them, and the Go distribution no longer ships
them. Instead, packages in the standard library are built as
needed and cached in the build cache, just like packages
outside GOROOT. This change reduces the size of the Go
distribution and also avoids C toolchain skew for packages that
use cgo. Refs jsc#PED-1962
* go command: The implementation of go test -json has been
improved to make it more robust. Programs that run go test
-json do not need any updates. Programs that invoke go tool
test2json directly should now run the test binary with
-v=test2json (for example, go test -v=test2json or ./pkg.test
-test.v=test2json) instead of plain -v.
* go command: A related change to go test -json is the addition
of an event with Action set to start at the beginning of each
test program's execution. When running multiple tests using the
go command, these start events are guaranteed to be emitted in
the same order as the packages named on the command line.
* go command: The go command now defines architecture feature
build tags, such as amd64.v2, to allow selecting a package
implementation file based on the presence or absence of a
particular architecture feature. See go help buildconstraint
for details.
* go command: The go subcommands now accept -C <dir> to change
directory to <dir> before performing the command, which may be
useful for scripts that need to execute commands in multiple
different modules.
* go command: The go build and go test commands no longer accept
the -i flag, which has been deprecated since Go 1.16.
* go command: The go generate command now accepts -skip <pattern>
to skip //go:generate directives matching <pattern>.
* go command: The go test command now accepts -skip <pattern> to
skip tests, subtests, or examples matching <pattern>.
* go command: When the main module is located within GOPATH/src,
go install no longer installs libraries for non-main packages
to GOPATH/pkg, and go list no longer reports a Target field for
such packages. (In module mode, compiled packages are stored in
the build cache only, but a bug had caused the GOPATH install
targets to unexpectedly remain in effect.)
* go command: The go build, go install, and other build-related
commands now support a -pgo flag that enables profile-guided
optimization, which is described in more detail in the Compiler
section below. The -pgo flag specifies the file path of the
profile. Specifying -pgo=auto causes the go command to search
for a file named default.pgo in the main package's directory
and use it if present. This mode currently requires a single
main package to be specified on the command line, but we plan
to lift this restriction in a future release. Specifying
-pgo=off turns off profile-guided optimization.
* go command: The go build, go install, and other build-related
commands now support a -cover flag that builds the specified
target with code coverage instrumentation. This is described in
more detail in the Cover section below.
* go version: The go version -m command now supports reading more
types of Go binaries, most notably, Windows DLLs built with go
build -buildmode=c-shared and Linux binaries without execute
permission.
* Cgo: The go command now disables cgo by default on systems
without a C toolchain. More specifically, when the CGO_ENABLED
environment variable is unset, the CC environment variable is
unset, and the default C compiler (typically clang or gcc) is
not found in the path, CGO_ENABLED defaults to 0. As always,
you can override the default by setting CGO_ENABLED explicitly.
The most important effect of the default change is that when Go
is installed on a system without a C compiler, it will now use
pure Go builds for packages in the standard library that use
cgo, instead of using pre-distributed package archives (which
have been removed, as noted above) or attempting to use cgo and
failing. This makes Go work better in some minimal container
environments as well as on macOS, where pre-distributed package
archives have not been used for cgo-based packages since Go
1.16.
The packages in the standard library that use cgo are net,
os/user, and plugin. On macOS, the net and os/user packages
have been rewritten not to use cgo: the same code is now used
for cgo and non-cgo builds as well as cross-compiled builds. On
Windows, the net and os/user packages have never used cgo. On
other systems, builds with cgo disabled will use a pure Go
version of these packages.
On macOS, the race detector has been rewritten not to use cgo:
race-detector-enabled programs can be built and run without
Xcode. On Linux and other Unix systems, and on Windows, a host
C toolchain is required to use the race detector.
* go cover: Go 1.20 supports collecting code coverage profiles
for programs (applications and integration tests), as opposed
to just unit tests. To collect coverage data for a program,
build it with go build's -cover flag, then run the resulting
binary with the environment variable GOCOVERDIR set to an
output directory for coverage profiles. See the 'coverage for
integration tests' landing page for more on how to get
started. For details on the design and implementation, see the
proposal.
* go vet: Improved detection of loop variable capture by nested
functions. The vet tool now reports references to loop
variables following a call to T.Parallel() within subtest
function bodies. Such references may observe the value of the
variable from a different iteration (typically causing test
cases to be skipped) or an invalid state due to unsynchronized
concurrent access.
* go vet: The tool also detects reference mistakes in more
places. Previously it would only consider the last statement
of the loop body, but now it recursively inspects the last
statements within if, switch, and select statements.
* go vet: New diagnostic for incorrect time formats. The vet tool
now reports use of the time format 2006-02-01 (yyyy-dd-mm) with
Time.Format and time.Parse. This format does not appear in
common date standards, but is frequently used by mistake when
attempting to use the ISO 8601 date format (yyyy-mm-dd).
* Runtime: Some of the garbage collector's internal data
structures were reorganized to be both more space and CPU
efficient. This change reduces memory overheads and improves
overall CPU performance by up to 2%.
* Runtime: The garbage collector behaves less erratically with
respect to goroutine assists in some circumstances.
* Runtime: Go 1.20 adds a new runtime/coverage package containing
APIs for writing coverage profile data at runtime from
long-running and/or server programs that do not terminate via
os.Exit().
* Compiler: Go 1.20 adds preview support for profile-guided
optimization (PGO). PGO enables the toolchain to perform
application- and workload-specific optimizations based on
run-time profile information. Currently, the compiler supports
pprof CPU profiles, which can be collected through usual means,
such as the runtime/pprof or net/http/pprof packages. To enable
PGO, pass the path of a pprof profile file via the -pgo flag to
go build, as mentioned above. Go 1.20 uses PGO to more
aggressively inline functions at hot call sites. Benchmarks for
a representative set of Go programs show enabling
profile-guided inlining optimization improves performance about
3–4%. See the PGO user guide for detailed documentation. We
plan to add more profile-guided optimizations in future
releases. Note that profile-guided optimization is a preview,
so please use it with appropriate caution.
* Compiler: The Go 1.20 compiler upgraded its front-end to use a
new way of handling the compiler's internal data, which fixes
several generic-types issues and enables type declarations
within generic functions and methods.
* Compiler: The compiler now rejects anonymous interface cycles
with a compiler error by default. These arise from tricky uses
of embedded interfaces and have always had subtle correctness
issues, yet we have no evidence that they're actually used in
practice. Assuming no reports from users adversely affected by
this change, we plan to update the language specification for
Go 1.22 to formally disallow them so tools authors can stop
supporting them too.
* Compiler: Go 1.18 and 1.19 saw regressions in build speed,
largely due to the addition of support for generics and
follow-on work. Go 1.20 improves build speeds by up to 10%,
bringing it back in line with Go 1.17. Relative to Go 1.19,
generated code performance is also generally slightly improved.
* Linker: On Linux, the linker now selects the dynamic
interpreter for glibc or musl at link time.
* Linker: On Windows, the Go linker now supports modern
LLVM-based C toolchains.
* Linker: Go 1.20 uses go: and type: prefixes for
compiler-generated symbols rather than go. and type.. This
avoids confusion for user packages whose name starts with
go.. The debug/gosym package understands this new naming
convention for binaries built with Go 1.20 and newer.
* Bootstrap: When building a Go release from source and
GOROOT_BOOTSTRAP is not set, previous versions of Go looked for
a Go 1.4 or later bootstrap toolchain in the directory
$HOME/go1.4 (%HOMEDRIVE%%HOMEPATH%\go1.4 on Windows). Go 1.18
and Go 1.19 looked first for $HOME/go1.17 or $HOME/sdk/go1.17
before falling back to $HOME/go1.4, in anticipation of
requiring Go 1.17 for use when bootstrapping Go 1.20. Go 1.20
does require a Go 1.17 release for bootstrapping, but we
realized that we should adopt the latest point release of the
bootstrap toolchain, so it requires Go 1.17.13. Go 1.20 looks
for $HOME/go1.17.13 or $HOME/sdk/go1.17.13 before falling back
to $HOME/go1.4 (to support systems that hard-coded the path
$HOME/go1.4 but have installed a newer Go toolchain there). In
the future, we plan to move the bootstrap toolchain forward
approximately once a year, and in particular we expect that Go
1.22 will require the final point release of Go 1.20 for
bootstrap.
* Library: Go 1.20 adds a new crypto/ecdh package to provide
explicit support for Elliptic Curve Diffie-Hellman key
exchanges over NIST curves and Curve25519. Programs should use
crypto/ecdh instead of the lower-level functionality in
crypto/elliptic for ECDH, and third-party modules for more
advanced use cases.
* Error handling: Go 1.20 expands support for error wrapping to
permit an error to wrap multiple other errors.
* Error handling: An error e can wrap more than one error by
providing an Unwrap method that returns a []error.
* Error handling: The errors.Is and errors.As functions have been
updated to inspect multiply wrapped errors.
* Error handling: The fmt.Errorf function now supports multiple
occurrences of the %w format verb, which will cause it to
return an error that wraps all of those error operands.
* Error handling: The new function errors.Join returns an error
wrapping a list of errors.
* HTTP ResponseController: The new "net/http".ResponseController
type provides access to extended per-request functionality not
handled by the "net/http".ResponseWriter interface. The
ResponseController type provides a clearer, more discoverable
way to add per-handler controls. Two such controls also added
in Go 1.20 are SetReadDeadline and SetWriteDeadline, which
allow setting per-request read and write deadlines.
* New ReverseProxy Rewrite hook: The httputil.ReverseProxy
forwarding proxy includes a new Rewrite hook function,
superseding the previous Director hook.
* archive/tar: When the GODEBUG=tarinsecurepath=0 environment
variable is set, Reader.Next method will now return the error
ErrInsecurePath for an entry with a file name that is an
absolute path, refers to a location outside the current
directory, contains invalid characters, or (on Windows) is a
reserved name such as NUL. A future version of Go may disable
insecure paths by default.
* archive/zip: When the GODEBUG=zipinsecurepath=0 environment
variable is set, NewReader will now return the error
ErrInsecurePath when opening an archive which contains any file
name that is an absolute path, refers to a location outside the
current directory, contains invalid characters, or (on Windows)
is a reserved names such as NUL. A future version of Go may
disable insecure paths by default.
* archive/zip: Reading from a directory file that contains file
data will now return an error. The zip specification does not
permit directory files to contain file data, so this change
only affects reading from invalid archives.
* bytes: The new CutPrefix and CutSuffix functions are like
TrimPrefix and TrimSuffix but also report whether the string
was trimmed.
* bytes: The new Clone function allocates a copy of a byte slice.
* context: The new WithCancelCause function provides a way to
cancel a context with a given error. That error can be
retrieved by calling the new Cause function.
* crypto/ecdsa: When using supported curves, all operations are
now implemented in constant time. This led to an increase in
CPU time between 5% and 30%, mostly affecting P-384 and P-521.
* crypto/ecdsa: The new PrivateKey.ECDH method converts an
ecdsa.PrivateKey to an ecdh.PrivateKey.
* crypto/ed25519: The PrivateKey.Sign method and the
VerifyWithOptions function now support signing pre-hashed
messages with Ed25519ph, indicated by an Options.HashFunc that
returns crypto.SHA512. They also now support Ed25519ctx and
Ed25519ph with context, indicated by setting the new
Options.Context field.
* crypto/rsa: The new field OAEPOptions.MGFHash allows
configuring the MGF1 hash separately for OAEP decryption.
* crypto/rsa: crypto/rsa now uses a new, safer, constant-time
backend. This causes a CPU runtime increase for decryption
operations between approximately 15% (RSA-2048 on amd64) and
45% (RSA-4096 on arm64), and more on 32-bit
architectures. Encryption operations are approximately 20x
slower than before (but still 5-10x faster than
decryption). Performance is expected to improve in future
releases. Programs must not modify or manually generate the
fields of PrecomputedValues.
* crypto/subtle: The new function XORBytes XORs two byte slices
together.
* crypto/tls: Parsed certificates are now shared across all
clients actively using that certificate. The memory savings can
be significant in programs that make many concurrent
connections to a server or collection of servers sharing any
part of their certificate chains.
* crypto/tls: For a handshake failure due to a certificate
verification failure, the TLS client and server now return an
error of the new type CertificateVerificationError, which
includes the presented certificates.
* crypto/x509: ParsePKCS8PrivateKey and MarshalPKCS8PrivateKey
now support keys of type *crypto/ecdh.PrivateKey.
ParsePKIXPublicKey and MarshalPKIXPublicKey now support keys of
type *crypto/ecdh.PublicKey. Parsing NIST curve keys still
returns values of type *ecdsa.PublicKey and *ecdsa.PrivateKey.
Use their new ECDH methods to convert to the crypto/ecdh types.
* crypto/x509: The new SetFallbackRoots function allows a program
to define a set of fallback root certificates in case an
operating system verifier or standard platform root bundle is
unavailable at runtime. It will most commonly be used with a
new package, golang.org/x/crypto/x509roots/fallback, which will
provide an up to date root bundle.
* debug/elf: Attempts to read from a SHT_NOBITS section using
Section.Data or the reader returned by Section.Open now return
an error.
* debug/elf: Additional R_LARCH_* constants are defined for use
with LoongArch systems.
* debug/elf: Additional R_PPC64_* constants are defined for use
with PPC64 ELFv2 relocations.
* debug/elf: The constant value for R_PPC64_SECTOFF_LO_DS is
corrected, from 61 to 62.
* debug/gosym: Due to a change of Go's symbol naming conventions,
tools that process Go binaries should use Go 1.20's debug/gosym
package to transparently handle both old and new binaries.
* debug/pe: Additional IMAGE_FILE_MACHINE_RISCV* constants are
defined for use with RISC-V systems.
* encoding/binary: The ReadVarint and ReadUvarint functions will
now return io.ErrUnexpectedEOF after reading a partial value,
rather than io.EOF.
* encoding/xml: The new Encoder.Close method can be used to check
for unclosed elements when finished encoding.
* encoding/xml: The decoder now rejects element and attribute
names with more than one colon, such as <a:b:c>, as well as
namespaces that resolve to an empty string, such as xmlns:a="".
* encoding/xml: The decoder now rejects elements that use
different namespace prefixes in the opening and closing tag,
even if those prefixes both denote the same namespace.
* errors: The new Join function returns an error wrapping a list
of errors.
* fmt: The Errorf function supports multiple occurrences of the
%w format verb, returning an error that unwraps to the list of
all arguments to %w.
* fmt: The new FormatString function recovers the formatting
directive corresponding to a State, which can be useful in
Formatter. implementations.
* go/ast: The new RangeStmt.Range field records the position of
the range keyword in a range statement.
* go/ast: The new File.FileStart and File.FileEnd fields record
the position of the start and end of the entire source file.
* go/token: The new FileSet.RemoveFile method removes a file from
a FileSet. Long-running programs can use this to release memory
associated with files they no longer need.
* go/types: The new Satisfies function reports whether a type
satisfies a constraint. This change aligns with the new
language semantics that distinguish satisfying a constraint
from implementing an interface.
* io: The new OffsetWriter wraps an underlying WriterAt and
provides Seek, Write, and WriteAt methods that adjust their
effective file offset position by a fixed amount.
* io/fs: The new error SkipAll terminates a WalkDir immediately
but successfully.
* math/big: The math/big package's wide scope and input-dependent
timing make it ill-suited for implementing cryptography. The
cryptography packages in the standard library no longer call
non-trivial Int methods on attacker-controlled inputs. In the
future, the determination of whether a bug in math/big is
considered a security vulnerability will depend on its wider
impact on the standard library.
* math/rand: The math/rand package now automatically seeds the
global random number generator (used by top-level functions
like Float64 and Int) with a random value, and the top-level
Seed function has been deprecated. Programs that need a
reproducible sequence of random numbers should prefer to
allocate their own random source, using
rand.New(rand.NewSource(seed)).
* math/rand: Programs that need the earlier consistent global
seeding behavior can set GODEBUG=randautoseed=0 in their
environment.
* math/rand: The top-level Read function has been deprecated. In
almost all cases, crypto/rand.Read is more appropriate.
* mime: The ParseMediaType function now allows duplicate
parameter names, so long as the values of the names are the
same.
* mime/multipart: Methods of the Reader type now wrap errors
returned by the underlying io.Reader.
* net: The LookupCNAME function now consistently returns the
contents of a CNAME record when one exists. Previously on Unix
systems and when using the pure Go resolver, LookupCNAME would
return an error if a CNAME record referred to a name that with
no A, AAAA, or CNAME record. This change modifies LookupCNAME
to match the previous behavior on Windows, allowing LookupCNAME
to succeed whenever a CNAME exists.
* net: Interface.Flags now includes the new flag FlagRunning,
indicating an operationally active interface. An interface
which is administratively configured but not active (for
example, because the network cable is not connected) will have
FlagUp set but not FlagRunning.
* net: The new Dialer.ControlContext field contains a callback
function similar to the existing Dialer.Control hook, that
additionally accepts the dial context as a parameter. Control
is ignored when ControlContext is not nil.
* net: The Go DNS resolver recognizes the trust-ad resolver
option. When options trust-ad is set in resolv.conf, the Go
resolver will set the AD bit in DNS queries. The resolver does
not make use of the AD bit in responses.
* net: DNS resolution will detect changes to /etc/nsswitch.conf
and reload the file when it changes. Checks are made at most
once every five seconds, matching the previous handling of
/etc/hosts and /etc/resolv.conf.
* net/http: The ResponseWriter.WriteHeader function now supports
sending 1xx status codes.
* net/http: The new Server.DisableGeneralOptionsHandler
configuration setting allows disabling the default OPTIONS *
handler.
* net/http: The new Transport.OnProxyConnectResponse hook is
called when a Transport receives an HTTP response from a proxy
for a CONNECT request.
* net/http: The HTTP server now accepts HEAD requests containing
a body, rather than rejecting them as invalid.
* net/http: HTTP/2 stream errors returned by net/http functions
may be converted to a golang.org/x/net/http2.StreamError using
errors.As.
* net/http: Leading and trailing spaces are trimmed from cookie
names, rather than being rejected as invalid. For example, a
cookie setting of "name =value" is now accepted as setting the
cookie "name".
* net/netip: The new IPv6LinkLocalAllRouters and IPv6Loopback
functions are the net/netip equivalents of net.IPv6loopback and
net.IPv6linklocalallrouters.
* os: On Windows, the name NUL is no longer treated as a special
case in Mkdir and Stat.
* os: On Windows, File.Stat now uses the file handle to retrieve
attributes when the file is a directory. Previously it would
use the path passed to Open, which may no longer be the file
represented by the file handle if the file has been moved or
replaced. This change modifies Open to open directories without
the FILE_SHARE_DELETE access, which match the behavior of
regular files.
* os: On Windows, File.Seek now supports seeking to the beginning
of a directory.
* os/exec: The new Cmd fields Cancel and WaitDelay specify the
behavior of the Cmd when its associated Context is canceled or
its process exits with I/O pipes still held open by a child
process.
* path/filepath: The new error SkipAll terminates a Walk
immediately but successfully.
* path/filepath: The new IsLocal function reports whether a path
is lexically local to a directory. For example, if IsLocal(p)
is true, then Open(p) will refer to a file that is lexically
within the subtree rooted at the current directory.
* reflect: The new Value.Comparable and Value.Equal methods can
be used to compare two Values for equality. Comparable reports
whether Equal is a valid operation for a given Value receiver.
* reflect: The new Value.Grow method extends a slice to guarantee
space for another n elements.
* reflect: The new Value.SetZero method sets a value to be the
zero value for its type.
* reflect: Go 1.18 introduced Value.SetIterKey and
Value.SetIterValue methods. These are optimizations:
v.SetIterKey(it) is meant to be equivalent to
v.Set(it.Key()). The implementations incorrectly omitted a
check for use of unexported fields that was present in the
unoptimized forms. Go 1.20 corrects these methods to include
the unexported field check.
* regexp: Go 1.19.2 and Go 1.18.7 included a security fix to the
regular expression parser, making it reject very large
expressions that would consume too much memory. Because Go
patch releases do not introduce new API, the parser returned
syntax.ErrInternalError in this case. Go 1.20 adds a more
specific error, syntax.ErrLarge, which the parser now returns
instead.
* runtime/cgo: Go 1.20 adds new Incomplete marker type. Code
generated by cgo will use cgo.Incomplete to mark an incomplete
C type.
* runtime/metrics: Go 1.20 adds new supported metrics, including
the current GOMAXPROCS setting (/sched/gomaxprocs:threads), the
number of cgo calls executed (/cgo/go-to-c-calls:calls), total
mutex block time (/sync/mutex/wait/total:seconds), and various
measures of time spent in garbage collection.
* runtime/metrics: Time-based histogram metrics are now less
precise, but take up much less memory.
* runtime/pprof: Mutex profile samples are now pre-scaled, fixing
an issue where old mutex profile samples would be scaled
incorrectly if the sampling rate changed during execution.
* runtime/pprof: Profiles collected on Windows now include memory
mapping information that fixes symbolization issues for
position-independent binaries.
* runtime/trace: The garbage collector's background sweeper now
yields less frequently, resulting in many fewer extraneous
events in execution traces.
* strings: The new CutPrefix and CutSuffix functions are like
TrimPrefix and TrimSuffix but also report whether the string
was trimmed.
* sync: The new Map methods Swap, CompareAndSwap, and
CompareAndDelete allow existing map entries to be updated
atomically.
* syscall: On FreeBSD, compatibility shims needed for FreeBSD 11
and earlier have been removed.
* syscall: On Linux, additional CLONE_* constants are defined for
use with the SysProcAttr.Cloneflags field.
* syscall: On Linux, the new SysProcAttr.CgroupFD and
SysProcAttr.UseCgroupFD fields provide a way to place a child
process into a specific cgroup.
* testing: The new method B.Elapsed reports the current elapsed
time of the benchmark, which may be useful for calculating
rates to report with ReportMetric.
* time: The new time layout constants DateTime, DateOnly, and
TimeOnly provide names for three of the most common layout
strings used in a survey of public Go source code.
* time: The new Time.Compare method compares two times.
* time: Parse now ignores sub-nanosecond precision in its input,
instead of reporting those digits as an error.
* time: The Time.MarshalJSON method is now more strict about
adherence to RFC 3339.
* unicode/utf16: The new AppendRune function appends the UTF-16
encoding of a given rune to a uint16 slice, analogous to
utf8.AppendRune.

%description
Go is an expressive, concurrent, garbage collected systems programming language
that is type safe and memory safe. It has pointers but no pointer arithmetic.
Go has fast builds, clean syntax, garbage collection, methods for any type, and
run-time reflection. It feels like a dynamic language but has the speed and
safety of a static language.
