## Description:

This update for go1.22 fixes the following issues:

  * go1.22.1 (released 2024-03-05) includes security fixes to the crypto/x509,
    html/template, net/http, net/http/cookiejar, and net/mail packages, as well
    as bug fixes to the compiler, the go command, the runtime, the trace
    command, and the go/types and net/http packages. (bsc#1218424)

  * go1.22 (released 2024-02-06) is a major release of Go. go1.22.x minor
    releases will be provided through February 2024.
    https://github.com/golang/go/wiki/Go-Release-Cycle go1.22 arrives six months
    after go1.21. 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. (bsc#1218424)

  * Language change: go1.22 makes two changes to for loops. Previously, the
    variables declared by a for loop were created once and updated by each
    iteration. In go1.22, each iteration of the loop creates new variables, to
    avoid accidental sharing bugs. The transition support tooling described in
    the proposal continues to work in the same way it did in Go 1.21.
  * Language change: For loops may now range over integers
  * Language change: go1.22 includes a preview of a language change we are
    considering for a future version of Go: range-over-function iterators.
    Building with GOEXPERIMENT=rangefunc enables this feature.
  * go command: Commands in workspaces can now use a vendor directory containing
    the dependencies of the workspace. The directory is created by go work
    vendor, and used by build commands when the -mod flag is set to vendor,
    which is the default when a workspace vendor directory is present. Note that
    the vendor directory's contents for a workspace are different from those of
    a single module: if the directory at the root of a workspace also contains
    one of the modules in the workspace, its vendor directory can contain the
    dependencies of either the workspace or of the module, but not both.
  * go get is no longer supported outside of a module in the legacy GOPATH mode
    (that is, with GO111MODULE=off). Other build commands, such as go build and
    go test, will continue to work indefinitely for legacy GOPATH programs.
  * go mod init no longer attempts to import module requirements from
    configuration files for other vendoring tools (such as Gopkg.lock).
  * go test -cover now prints coverage summaries for covered packages that do
    not have their own test files. Prior to Go 1.22 a go test -cover run for
    such a package would report: ? mymod/mypack [no test files] and now with
    go1.22, functions in the package are treated as uncovered: mymod/mypack
    coverage: 0.0% of statements Note that if a package contains no executable
    code at all, we can't report a meaningful coverage percentage; for such
    packages the go tool will continue to report that there are no test files.
  * trace: The trace tool's web UI has been gently refreshed as part of the work
    to support the new tracer, resolving several issues and improving the
    readability of various sub-pages. The web UI now supports exploring traces
    in a thread-oriented view. The trace viewer also now displays the full
    duration of all system calls. These improvements only apply for viewing
    traces produced by programs built with go1.22 or newer. A future release
    will bring some of these improvements to traces produced by older version of
    Go.
  * vet: References to loop variables The behavior of the vet tool has changed
    to match the new semantics (see above) of loop variables in go1.22. When
    analyzing a file that requires go1.22 or newer (due to its go.mod file or a
    per-file build constraint), vetcode> no longer reports references to loop
    variables from within a function literal that might outlive the iteration of
    the loop. In Go 1.22, loop variables are created anew for each iteration, so
    such references are no longer at risk of using a variable after it has been
    updated by the loop.
  * vet: New warnings for missing values after append The vet tool now reports
    calls to append that pass no values to be appended to the slice, such as
    slice = append(slice). Such a statement has no effect, and experience has
    shown that is nearly always a mistake.
  * vet: New warnings for deferring time.Since The vet tool now reports a non-
    deferred call to time.Since(t) within a defer statement. This is equivalent
    to calling time.Now().Sub(t) before the defer statement, not when the
    deferred function is called. In nearly all cases, the correct code requires
    deferring the time.Since call.
  * vet: New warnings for mismatched key-value pairs in log/slog calls The vet
    tool now reports invalid arguments in calls to functions and methods in the
    structured logging package, log/slog, that accept alternating key/value
    pairs. It reports calls where an argument in a key position is neither a
    string nor a slog.Attr, and where a final key is missing its value.
  * runtime: The runtime now keeps type-based garbage collection metadata nearer
    to each heap object, improving the CPU performance (latency or throughput)
    of Go programs by 1-3%. This change also reduces the memory overhead of the
    majority Go programs by approximately 1% by deduplicating redundant
    metadata. Some programs may see a smaller improvement because this change
    adjusts the size class boundaries of the memory allocator, so some objects
    may be moved up a size class. A consequence of this change is that some
    objects' addresses that were previously always aligned to a 16 byte (or
    higher) boundary will now only be aligned to an 8 byte boundary. Some
    programs that use assembly instructions that require memory addresses to be
    more than 8-byte aligned and rely on the memory allocator's previous
    alignment behavior may break, but we expect such programs to be rare. Such
    programs may be built with GOEXPERIMENT=noallocheaders to revert to the old
    metadata layout and restore the previous alignment behavior, but package
    owners should update their assembly code to avoid the alignment assumption,
    as this workaround will be removed in a future release.
  * runtime: On the windows/amd64 port, programs linking or loading Go libraries
    built with -buildmode=c-archive or -buildmode=c-shared can now use the
    SetUnhandledExceptionFilter Win32 function to catch exceptions not handled
    by the Go runtime. Note that this was already supported on the windows/386
    port.
  * compiler: Profile-guided Optimization (PGO) builds can now devirtualize a
    higher proportion of calls than previously possible. Most programs from a
    representative set of Go programs now see between 2 and 14% improvement from
    enabling PGO.
  * compiler: The compiler now interleaves devirtualization and inlining, so
    interface method calls are better optimized.
  * compiler: go1.22 also includes a preview of an enhanced implementation of
    the compiler's inlining phase that uses heuristics to boost inlinability at
    call sites deemed "important" (for example, in loops) and discourage
    inlining at call sites deemed "unimportant" (for example, on panic paths).
    Building with GOEXPERIMENT=newinliner enables the new call-site heuristics;
    see issue #61502 for more info and to provide feedback.
  * linker: The linker's -s and -w flags are now behave more consistently across
    all platforms. The -w flag suppresses DWARF debug information generation.
    The -s flag suppresses symbol table generation. The -s flag also implies the
    -w flag, which can be negated with -w=0. That is, -s -w=0 will generate a
    binary with DWARF debug information generation but without the symbol table.
  * linker: On ELF platforms, the -B linker flag now accepts a special form:
    with -B gobuildid, the linker will generate a GNU build ID (the ELF
    NT_GNU_BUILD_ID note) derived from the Go build ID.
  * linker: On Windows, when building with -linkmode=internal, the linker now
    preserves SEH information from C object files by copying the .pdata and
    .xdata sections into the final binary. This helps with debugging and
    profiling binaries using native tools, such as WinDbg. Note that until now,
    C functions' SEH exception handlers were not being honored, so this change
    may cause some programs to behave differently. -linkmode=external is not
    affected by this change, as external linkers already preserve SEH
    information.
  * bootstrap: As mentioned in the Go 1.20 release notes, go1.22 now requires
    the final point release of Go 1.20 or later for bootstrap. We expect that Go
    1.24 will require the final point release of go1.22 or later for bootstrap.
  * core library: New math/rand/v2 package: go1.22 includes the first “v2”
    package in the standard library, math/rand/v2. The changes compared to
    math/rand are detailed in proposal go#61716. The most important changes are:
    * The Read method, deprecated in math/rand, was not carried forward for math/rand/v2. (It remains available in math/rand.) The vast majority of calls to Read should use crypto/rand’s Read instead. Otherwise a custom Read can be constructed using the Uint64 method.
    * The global generator accessed by top-level functions is unconditionally randomly seeded. Because the API guarantees no fixed sequence of results, optimizations like per-thread random generator states are now possible.
    * The Source interface now has a single Uint64 method; there is no Source64 interface.
    * Many methods now use faster algorithms that were not possible to adopt in math/rand because they changed the output streams.
    * The Intn, Int31, Int31n, Int63, and Int64n top-level functions and methods from math/rand are spelled more idiomatically in math/rand/v2: IntN, Int32, Int32N, Int64, and Int64N. There are also new top-level functions and methods Uint32, Uint32N, Uint64, Uint64N, Uint, and UintN.
    * The new generic function N is like Int64N or Uint64N but works for any integer type. For example a random duration from 0 up to 5 minutes is rand.N(5*time.Minute).
    * The Mitchell & Reeds LFSR generator provided by math/rand’s Source has been replaced by two more modern pseudo-random generator sources: ChaCha8 PCG. ChaCha8 is a new, cryptographically strong random number generator roughly similar to PCG in efficiency. ChaCha8 is the algorithm used for the top-level functions in math/rand/v2. As of go1.22, math/rand's top-level functions (when not explicitly seeded) and the Go runtime also use ChaCha8 for randomness.
    * We plan to include an API migration tool in a future release, likely Go 1.23.
  * core library: New go/version package: The new go/version package implements
    functions for validating and comparing Go version strings.
  * core library: Enhanced routing patterns: HTTP routing in the standard
    library is now more expressive. The patterns used by net/http.ServeMux have
    been enhanced to accept methods and wildcards. This change breaks backwards
    compatibility in small ways, some obvious—patterns with "{" and "}" behave
    differently— and some less so—treatment of escaped paths has been improved.
    The change is controlled by a GODEBUG field named httpmuxgo121. Set
    httpmuxgo121=1 to restore the old behavior.
  * Minor changes to the library As always, there are various minor changes and
    updates to the library, made with the Go 1 promise of compatibility in mind.
    There are also various performance improvements, not enumerated here.
  * archive/tar: The new method Writer.AddFS adds all of the files from an fs.FS
    to the archive.
  * archive/zip: The new method Writer.AddFS adds all of the files from an fs.FS
    to the archive.
  * bufio: When a SplitFunc returns ErrFinalToken with a nil token, Scanner will
    now stop immediately. Previously, it would report a final empty token before
    stopping, which was usually not desired. Callers that do want to report a
    final empty token can do so by returning []byte{} rather than nil.
  * cmp: The new function Or returns the first in a sequence of values that is
    not the zero value.
  * crypto/tls: ConnectionState.ExportKeyingMaterial will now return an error
    unless TLS 1.3 is in use, or the extended_master_secret extension is
    supported by both the server and client. crypto/tls has supported this
    extension since Go 1.20. This can be disabled with the tlsunsafeekm=1
    GODEBUG setting.
  * crypto/tls: By default, the minimum version offered by crypto/tls servers is
    now TLS 1.2 if not specified with config.MinimumVersion, matching the
    behavior of crypto/tls clients. This change can be reverted with the
    tls10server=1 GODEBUG setting.
  * crypto/tls: By default, cipher suites without ECDHE support are no longer
    offered by either clients or servers during pre-TLS 1.3 handshakes. This
    change can be reverted with the tlsrsakex=1 GODEBUG setting.
  * crypto/x509: The new CertPool.AddCertWithConstraint method can be used to
    add customized constraints to root certificates to be applied during chain
    building.
  * crypto/x509: On Android, root certificates will now be loaded from
    /data/misc/keychain/certs-added as well as /system/etc/security/cacerts.
  * crypto/x509: A new type, OID, supports ASN.1 Object Identifiers with
    individual components larger than 31 bits. A new field which uses this type,
    Policies, is added to the Certificate struct, and is now populated during
    parsing. Any OIDs which cannot be represented using a asn1.ObjectIdentifier
    will appear in Policies, but not in the old PolicyIdentifiers field. When
    calling CreateCertificate, the Policies field is ignored, and policies are
    taken from the PolicyIdentifiers field. Using the x509usepolicies=1 GODEBUG
    setting inverts this, populating certificate policies from the Policies
    field, and ignoring the PolicyIdentifiers field. We may change the default
    value of x509usepolicies in Go 1.23, making Policies the default field for
    marshaling.
  * database/sql: The new Null[T] type provide a way to scan nullable columns
    for any column types.
  * debug/elf: Constant R_MIPS_PC32 is defined for use with MIPS64 systems.
    Additional R_LARCH_* constants are defined for use with LoongArch systems.
  * encoding: The new methods AppendEncode and AppendDecode added to each of the
    Encoding types in the packages encoding/base32, encoding/base64, and
    encoding/hex simplify encoding and decoding from and to byte slices by
    taking care of byte slice buffer management.
  * encoding: The methods base32.Encoding.WithPadding and
    base64.Encoding.WithPadding now panic if the padding argument is a negative
    value other than NoPadding.
  * encoding/json: Marshaling and encoding functionality now escapes '\b' and
    '\f' characters as \b and \f instead of \u0008 and \u000c.
  * go/ast: The following declarations related to syntactic identifier
    resolution are now deprecated: Ident.Obj, Object, Scope, File.Scope,
    File.Unresolved, Importer, Package, NewPackage. In general, identifiers
    cannot be accurately resolved without type information. Consider, for
    example, the identifier K in T{K: ""}: it could be the name of a local
    variable if T is a map type, or the name of a field if T is a struct type.
    New programs should use the go/types package to resolve identifiers; see
    Object, Info.Uses, and Info.Defs for details.
  * go/ast: The new ast.Unparen function removes any enclosing parentheses from
    an expression.
  * go/types: The new Alias type represents type aliases. Previously, type
    aliases were not represented explicitly, so a reference to a type alias was
    equivalent to spelling out the aliased type, and the name of the alias was
    lost. The new representation retains the intermediate Alias. This enables
    improved error reporting (the name of a type alias can be reported), and
    allows for better handling of cyclic type declarations involving type
    aliases. In a future release, Alias types will also carry type parameter
    information. The new function Unalias returns the actual type denoted by an
    Alias type (or any other Type for that matter).
  * go/types: Because Alias types may break existing type switches that do not
    know to check for them, this functionality is controlled by a GODEBUG field
    named gotypesalias. With gotypesalias=0, everything behaves as before, and
    Alias types are never created. With gotypesalias=1, Alias types are created
    and clients must expect them. The default is gotypesalias=0. In a future
    release, the default will be changed to gotypesalias=1. Clients of go/types
    are urged to adjust their code as soon as possible to work with
    gotypesalias=1 to eliminate problems early.
  * go/types: The Info struct now exports the FileVersions map which provides
    per-file Go version information.
  * go/types: The new helper method PkgNameOf returns the local package name for
    the given import declaration.
  * go/types: The implementation of SizesFor has been adjusted to compute the
    same type sizes as the compiler when the compiler argument for SizesFor is
    "gc". The default Sizes implementation used by the type checker is now
    types.SizesFor("gc", "amd64").
  * go/types: The start position (Pos) of the lexical environment block (Scope)
    that represents a function body has changed: it used to start at the opening
    curly brace of the function body, but now starts at the function's func
    token.
  * html/template: Javascript template literals may now contain Go template
    actions, and parsing a template containing one will no longer return
    ErrJSTemplate. Similarly the GODEBUG setting jstmpllitinterp no longer has
    any effect.
  * io: The new SectionReader.Outer method returns the ReaderAt, offset, and
    size passed to NewSectionReader.
  * log/slog: The new SetLogLoggerLevel function controls the level for the
    bridge between the `slog` and `log` packages. It sets the minimum level for
    calls to the top-level `slog` logging functions, and it sets the level for
    calls to `log.Logger` that go through `slog`.
  * math/big: The new method Rat.FloatPrec computes the number of fractional
    decimal digits required to represent a rational number accurately as a
    floating-point number, and whether accurate decimal representation is
    possible in the first place.
  * net: When io.Copy copies from a TCPConn to a UnixConn, it will now use
    Linux's splice(2) system call if possible, using the new method
    TCPConn.WriteTo.
  * net: The Go DNS Resolver, used when building with "-tags=netgo", now
    searches for a matching name in the Windows hosts file, located at
    %SystemRoot%\System32\drivers\etc\hosts, before making a DNS query.
  * net/http: The new functions ServeFileFS, FileServerFS, and
    NewFileTransportFS are versions of the existing ServeFile, FileServer, and
    NewFileTransport, operating on an fs.FS.
  * net/http: The HTTP server and client now reject requests and responses
    containing an invalid empty Content-Length header. The previous behavior may
    be restored by setting GODEBUG field httplaxcontentlength=1.
  * net/http: The new method Request.PathValue returns path wildcard values from
    a request and the new method Request.SetPathValue sets path wildcard values
    on a request.
  * net/http/cgi: When executing a CGI process, the PATH_INFO variable is now
    always set to the empty string or a value starting with a / character, as
    required by RFC 3875. It was previously possible for some combinations of
    Handler.Root and request URL to violate this requirement.
  * net/netip: The new AddrPort.Compare method compares two AddrPorts.
  * os: On Windows, the Stat function now follows all reparse points that link
    to another named entity in the system. It was previously only following
    IO_REPARSE_TAG_SYMLINK and IO_REPARSE_TAG_MOUNT_POINT reparse points.
  * os: On Windows, passing O_SYNC to OpenFile now causes write operations to go
    directly to disk, equivalent to O_SYNC on Unix platforms.
  * os: On Windows, the ReadDir, File.ReadDir, File.Readdir, and
    File.Readdirnames functions now read directory entries in batches to reduce
    the number of system calls, improving performance up to 30%.
  * os: When io.Copy copies from a File to a net.UnixConn, it will now use
    Linux's sendfile(2) system call if possible, using the new method
    File.WriteTo.
  * os/exec: On Windows, LookPath now ignores empty entries in %PATH%, and
    returns ErrNotFound (instead of ErrNotExist) if no executable file extension
    is found to resolve an otherwise-unambiguous name.
  * os/exec: On Windows, Command and Cmd.Start no longer call LookPath if the
    path to the executable is already absolute and has an executable file
    extension. In addition, Cmd.Start no longer writes the resolved extension
    back to the Path field, so it is now safe to call the String method
    concurrently with a call to Start.
  * reflect: The Value.IsZero method will now return true for a floating-point
    or complex negative zero, and will return true for a struct value if a blank
    field (a field named _) somehow has a non-zero value. These changes make
    IsZero consistent with comparing a value to zero using the language ==
    operator.
  * reflect: The PtrTo function is deprecated, in favor of PointerTo.
  * reflect: The new function TypeFor returns the Type that represents the type
    argument T. Previously, to get the reflect.Type value for a type, one had to
    use reflect.TypeOf((*T)(nil)).Elem(). This may now be written as
    reflect.TypeForT.
  * runtime/metrics: Four new histogram metrics
    /sched/pauses/stopping/gc:seconds, /sched/pauses/stopping/other:seconds,
    /sched/pauses/total/gc:seconds, and /sched/pauses/total/other:seconds
    provide additional details about stop-the-world pauses. The "stopping"
    metrics report the time taken from deciding to stop the world until all
    goroutines are stopped. The "total" metrics report the time taken from
    deciding to stop the world until it is started again.
  * runtime/metrics: The /gc/pauses:seconds metric is deprecated, as it is
    equivalent to the new /sched/pauses/total/gc:seconds metric.
  * runtime/metrics: /sync/mutex/wait/total:seconds now includes contention on
    runtime-internal locks in addition to sync.Mutex and sync.RWMutex.
  * runtime/pprof: Mutex profiles now scale contention by the number of
    goroutines blocked on the mutex. This provides a more accurate
    representation of the degree to which a mutex is a bottleneck in a Go
    program. For instance, if 100 goroutines are blocked on a mutex for 10
    milliseconds, a mutex profile will now record 1 second of delay instead of
    10 milliseconds of delay.
  * runtime/pprof: Mutex profiles also now include contention on runtime-
    internal locks in addition to sync.Mutex and sync.RWMutex. Contention on
    runtime-internal locks is always reported at
    runtime._LostContendedRuntimeLock. A future release will add complete stack
    traces in these cases.
  * runtime/pprof: CPU profiles on Darwin platforms now contain the process's
    memory map, enabling the disassembly view in the pprof tool.
  * runtime/trace: The execution tracer has been completely overhauled in this
    release, resolving several long-standing issues and paving the way for new
    use-cases for execution traces.
  * runtime/trace: Execution traces now use the operating system's clock on most
    platforms (Windows excluded) so it is possible to correlate them with traces
    produced by lower-level components. Execution traces no longer depend on the
    reliability of the platform's clock to produce a correct trace. Execution
    traces are now partitioned regularly on-the-fly and as a result may be
    processed in a streamable way. Execution traces now contain complete
    durations for all system calls. Execution traces now contain information
    about the operating system threads that goroutines executed on. The latency
    impact of starting and stopping execution traces has been dramatically
    reduced. Execution traces may now begin or end during the garbage collection
    mark phase.
  * runtime/trace: To allow Go developers to take advantage of these
    improvements, an experimental trace reading package is available at
    golang.org/x/exp/trace. Note that this package only works on traces produced
    by programs built with go1.22 at the moment. Please try out the package and
    provide feedback on the corresponding proposal issue.
  * runtime/trace: If you experience any issues with the new execution tracer
    implementation, you may switch back to the old implementation by building
    your Go program with GOEXPERIMENT=noexectracer2. If you do, please file an
    issue, otherwise this option will be removed in a future release.
  * slices: The new function Concat concatenates multiple slices.
  * slices: Functions that shrink the size of a slice (Delete, DeleteFunc,
    Compact, CompactFunc, and Replace) now zero the elements between the new
    length and the old length.
  * slices: Insert now always panics if the argument i is out of range.
    Previously it did not panic in this situation if there were no elements to
    be inserted.
  * syscall: The syscall package has been frozen since Go 1.4 and was marked as
    deprecated in Go 1.11, causing many editors to warn about any use of the
    package. However, some non-deprecated functionality requires use of the
    syscall package, such as the os/exec.Cmd.SysProcAttr field. To avoid
    unnecessary complaints on such code, the syscall package is no longer marked
    as deprecated. The package remains frozen to most new functionality, and new
    code remains encouraged to use golang.org/x/sys/unix or
    golang.org/x/sys/windows where possible.
  * syscall: On Linux, the new SysProcAttr.PidFD field allows obtaining a PID FD
    when starting a child process via StartProcess or os/exec.
  * syscall: On Windows, passing O_SYNC to Open now causes write operations to
    go directly to disk, equivalent to O_SYNC on Unix platforms.
  * testing/slogtest: The new Run function uses sub-tests to run test cases,
    providing finer-grained control.
  * Ports: Darwin: On macOS on 64-bit x86 architecture (the darwin/amd64 port),
    the Go toolchain now generates position-independent executables (PIE) by
    default. Non-PIE binaries can be generated by specifying the -buildmode=exe
    build flag. On 64-bit ARM-based macOS (the darwin/arm64 port), the Go
    toolchain already generates PIE by default. go1.22 is the last release that
    will run on macOS 10.15 Catalina. Go 1.23 will require macOS 11 Big Sur or
    later.
  * Ports: Arm: The GOARM environment variable now allows you to select whether
    to use software or hardware floating point. Previously, valid GOARM values
    were 5, 6, or 7. Now those same values can be optionally followed by
    ,softfloat or ,hardfloat to select the floating-point implementation. This
    new option defaults to softfloat for version 5 and hardfloat for versions 6
    and 7.
  * Ports: Loong64: The loong64 port now supports passing function arguments and
    results using registers. The linux/loong64 port now supports the address
    sanitizer, memory sanitizer, new-style linker relocations, and the plugin
    build mode.

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. (bsc#1218424) * Language change: go1.22 makes two changes to for loops. Previously, the variables declared by a for loop were created once and updated by each iteration. In go1.22, each iteration of the loop creates new variables, to avoid accidental sharing bugs. The transition support tooling described in the proposal continues to work in the same way it did in Go 1.21. * Language change: For loops may now range over integers * Language change: go1.22 includes a preview of a language change we are considering for a future version of Go: range-over-function iterators. Building with GOEXPERIMENT=rangefunc enables this feature. * go command: Commands in workspaces can now use a vendor directory containing the dependencies of the workspace. The directory is created by go work vendor, and used by build commands when the -mod flag is set to vendor, which is the default when a workspace vendor directory is present. Note that the vendor directory's contents for a workspace are different from those of a single module: if the directory at the root of a workspace also contains one of the modules in the workspace, its vendor directory can contain the dependencies of either the workspace or of the module, but not both. * go get is no longer supported outside of a module in the legacy GOPATH mode (that is, with GO111MODULE=off). Other build commands, such as go build and go test, will continue to work indefinitely for legacy GOPATH programs. * go mod init no longer attempts to import module requirements from configuration files for other vendoring tools (such as Gopkg.lock). * go test -cover now prints coverage summaries for covered packages that do not have their own test files. Prior to Go 1.22 a go test -cover run for such a package would report: ? mymod/mypack [no test files] and now with go1.22, functions in the package are treated as uncovered: mymod/mypack coverage: 0.0% of statements Note that if a package contains no executable code at all, we can't report a meaningful coverage percentage; for such packages the go tool will continue to report that there are no test files. * trace: The trace tool's web UI has been gently refreshed as part of the work to support the new tracer, resolving several issues and improving the readability of various sub-pages. The web UI now supports exploring traces in a thread-oriented view. The trace viewer also now displays the full duration of all system calls. These improvements only apply for viewing traces produced by programs built with go1.22 or newer. A future release will bring some of these improvements to traces produced by older version of Go. * vet: References to loop variables The behavior of the vet tool has changed to match the new semantics (see above) of loop variables in go1.22. When analyzing a file that requires go1.22 or newer (due to its go.mod file or a per-file build constraint), vetcode> no longer reports references to loop variables from within a function literal that might outlive the iteration of the loop. In Go 1.22, loop variables are created anew for each iteration, so such references are no longer at risk of using a variable after it has been updated by the loop. * vet: New warnings for missing values after append The vet tool now reports calls to append that pass no values to be appended to the slice, such as slice = append(slice). Such a statement has no effect, and experience has shown that is nearly always a mistake. * vet: New warnings for deferring time.Since The vet tool now reports a non- deferred call to time.Since(t) within a defer statement. This is equivalent to calling time.Now().Sub(t) before the defer statement, not when the deferred function is called. In nearly all cases, the correct code requires deferring the time.Since call. * vet: New warnings for mismatched key-value pairs in log/slog calls The vet tool now reports invalid arguments in calls to functions and methods in the structured logging package, log/slog, that accept alternating key/value pairs. It reports calls where an argument in a key position is neither a string nor a slog.Attr, and where a final key is missing its value. * runtime: The runtime now keeps type-based garbage collection metadata nearer to each heap object, improving the CPU performance (latency or throughput) of Go programs by 1-3%. This change also reduces the memory overhead of the majority Go programs by approximately 1% by deduplicating redundant metadata. Some programs may see a smaller improvement because this change adjusts the size class boundaries of the memory allocator, so some objects may be moved up a size class. A consequence of this change is that some objects' addresses that were previously always aligned to a 16 byte (or higher) boundary will now only be aligned to an 8 byte boundary. Some programs that use assembly instructions that require memory addresses to be more than 8-byte aligned and rely on the memory allocator's previous alignment behavior may break, but we expect such programs to be rare. Such programs may be built with GOEXPERIMENT=noallocheaders to revert to the old metadata layout and restore the previous alignment behavior, but package owners should update their assembly code to avoid the alignment assumption, as this workaround will be removed in a future release. * runtime: On the windows/amd64 port, programs linking or loading Go libraries built with -buildmode=c-archive or -buildmode=c-shared can now use the SetUnhandledExceptionFilter Win32 function to catch exceptions not handled by the Go runtime. Note that this was already supported on the windows/386 port. * compiler: Profile-guided Optimization (PGO) builds can now devirtualize a higher proportion of calls than previously possible. Most programs from a representative set of Go programs now see between 2 and 14% improvement from enabling PGO. * compiler: The compiler now interleaves devirtualization and inlining, so interface method calls are better optimized. * compiler: go1.22 also includes a preview of an enhanced implementation of the compiler's inlining phase that uses heuristics to boost inlinability at call sites deemed "important" (for example, in loops) and discourage inlining at call sites deemed "unimportant" (for example, on panic paths). Building with GOEXPERIMENT=newinliner enables the new call-site heuristics; see issue #61502 for more info and to provide feedback. * linker: The linker's -s and -w flags are now behave more consistently across all platforms. The -w flag suppresses DWARF debug information generation. The -s flag suppresses symbol table generation. The -s flag also implies the -w flag, which can be negated with -w=0. That is, -s -w=0 will generate a binary with DWARF debug information generation but without the symbol table. * linker: On ELF platforms, the -B linker flag now accepts a special form: with -B gobuildid, the linker will generate a GNU build ID (the ELF NT_GNU_BUILD_ID note) derived from the Go build ID. * linker: On Windows, when building with -linkmode=internal, the linker now preserves SEH information from C object files by copying the .pdata and .xdata sections into the final binary. This helps with debugging and profiling binaries using native tools, such as WinDbg. Note that until now, C functions' SEH exception handlers were not being honored, so this change may cause some programs to behave differently. -linkmode=external is not affected by this change, as external linkers already preserve SEH information. * bootstrap: As mentioned in the Go 1.20 release notes, go1.22 now requires the final point release of Go 1.20 or later for bootstrap. We expect that Go 1.24 will require the final point release of go1.22 or later for bootstrap. * core library: New math/rand/v2 package: go1.22 includes the first “v2” package in the standard library, math/rand/v2. The changes compared to math/rand are detailed in proposal go#61716. The most important changes are: * The Read method, deprecated in math/rand, was not carried forward for math/rand/v2. (It remains available in math/rand.) The vast majority of calls to Read should use crypto/rand’s Read instead. Otherwise a custom Read can be constructed using the Uint64 method. * The global generator accessed by top-level functions is unconditionally randomly seeded. Because the API guarantees no fixed sequence of results, optimizations like per-thread random generator states are now possible. * The Source interface now has a single Uint64 method; there is no Source64 interface. * Many methods now use faster algorithms that were not possible to adopt in math/rand because they changed the output streams. * The Intn, Int31, Int31n, Int63, and Int64n top-level functions and methods from math/rand are spelled more idiomatically in math/rand/v2: IntN, Int32, Int32N, Int64, and Int64N. There are also new top-level functions and methods Uint32, Uint32N, Uint64, Uint64N, Uint, and UintN. * The new generic function N is like Int64N or Uint64N but works for any integer type. For example a random duration from 0 up to 5 minutes is rand.N(5*time.Minute). * The Mitchell & Reeds LFSR generator provided by math/rand’s Source has been replaced by two more modern pseudo-random generator sources: ChaCha8 PCG. ChaCha8 is a new, cryptographically strong random number generator roughly similar to PCG in efficiency. ChaCha8 is the algorithm used for the top-level functions in math/rand/v2. As of go1.22, math/rand's top-level functions (when not explicitly seeded) and the Go runtime also use ChaCha8 for randomness. * We plan to include an API migration tool in a future release, likely Go 1.23. * core library: New go/version package: The new go/version package implements functions for validating and comparing Go version strings. * core library: Enhanced routing patterns: HTTP routing in the standard library is now more expressive. The patterns used by net/http.ServeMux have been enhanced to accept methods and wildcards. This change breaks backwards compatibility in small ways, some obvious—patterns with "{" and "}" behave differently— and some less so—treatment of escaped paths has been improved. The change is controlled by a GODEBUG field named httpmuxgo121. Set httpmuxgo121=1 to restore the old behavior. * Minor changes to the library As always, there are various minor changes and updates to the library, made with the Go 1 promise of compatibility in mind. There are also various performance improvements, not enumerated here. * archive/tar: The new method Writer.AddFS adds all of the files from an fs.FS to the archive. * archive/zip: The new method Writer.AddFS adds all of the files from an fs.FS to the archive. * bufio: When a SplitFunc returns ErrFinalToken with a nil token, Scanner will now stop immediately. Previously, it would report a final empty token before stopping, which was usually not desired. Callers that do want to report a final empty token can do so by returning []byte{} rather than nil. * cmp: The new function Or returns the first in a sequence of values that is not the zero value. * crypto/tls: ConnectionState.ExportKeyingMaterial will now return an error unless TLS 1.3 is in use, or the extended_master_secret extension is supported by both the server and client. crypto/tls has supported this extension since Go 1.20. This can be disabled with the tlsunsafeekm=1 GODEBUG setting. * crypto/tls: By default, the minimum version offered by crypto/tls servers is now TLS 1.2 if not specified with config.MinimumVersion, matching the behavior of crypto/tls clients. This change can be reverted with the tls10server=1 GODEBUG setting. * crypto/tls: By default, cipher suites without ECDHE support are no longer offered by either clients or servers during pre-TLS 1.3 handshakes. This change can be reverted with the tlsrsakex=1 GODEBUG setting. * crypto/x509: The new CertPool.AddCertWithConstraint method can be used to add customized constraints to root certificates to be applied during chain building. * crypto/x509: On Android, root certificates will now be loaded from /data/misc/keychain/certs-added as well as /system/etc/security/cacerts. * crypto/x509: A new type, OID, supports ASN.1 Object Identifiers with individual components larger than 31 bits. A new field which uses this type, Policies, is added to the Certificate struct, and is now populated during parsing. Any OIDs which cannot be represented using a asn1.ObjectIdentifier will appear in Policies, but not in the old PolicyIdentifiers field. When calling CreateCertificate, the Policies field is ignored, and policies are taken from the PolicyIdentifiers field. Using the x509usepolicies=1 GODEBUG setting inverts this, populating certificate policies from the Policies field, and ignoring the PolicyIdentifiers field. We may change the default value of x509usepolicies in Go 1.23, making Policies the default field for marshaling. * database/sql: The new Null[T] type provide a way to scan nullable columns for any column types. * debug/elf: Constant R_MIPS_PC32 is defined for use with MIPS64 systems. Additional R_LARCH_* constants are defined for use with LoongArch systems. * encoding: The new methods AppendEncode and AppendDecode added to each of the Encoding types in the packages encoding/base32, encoding/base64, and encoding/hex simplify encoding and decoding from and to byte slices by taking care of byte slice buffer management. * encoding: The methods base32.Encoding.WithPadding and base64.Encoding.WithPadding now panic if the padding argument is a negative value other than NoPadding. * encoding/json: Marshaling and encoding functionality now escapes '\b' and '\f' characters as \b and \f instead of \u0008 and \u000c. * go/ast: The following declarations related to syntactic identifier resolution are now deprecated: Ident.Obj, Object, Scope, File.Scope, File.Unresolved, Importer, Package, NewPackage. In general, identifiers cannot be accurately resolved without type information. Consider, for example, the identifier K in T{K: ""}: it could be the name of a local variable if T is a map type, or the name of a field if T is a struct type. New programs should use the go/types package to resolve identifiers; see Object, Info.Uses, and Info.Defs for details. * go/ast: The new ast.Unparen function removes any enclosing parentheses from an expression. * go/types: The new Alias type represents type aliases. Previously, type aliases were not represented explicitly, so a reference to a type alias was equivalent to spelling out the aliased type, and the name of the alias was lost. The new representation retains the intermediate Alias. This enables improved error reporting (the name of a type alias can be reported), and allows for better handling of cyclic type declarations involving type aliases. In a future release, Alias types will also carry type parameter information. The new function Unalias returns the actual type denoted by an Alias type (or any other Type for that matter). * go/types: Because Alias types may break existing type switches that do not know to check for them, this functionality is controlled by a GODEBUG field named gotypesalias. With gotypesalias=0, everything behaves as before, and Alias types are never created. With gotypesalias=1, Alias types are created and clients must expect them. The default is gotypesalias=0. In a future release, the default will be changed to gotypesalias=1. Clients of go/types are urged to adjust their code as soon as possible to work with gotypesalias=1 to eliminate problems early. * go/types: The Info struct now exports the FileVersions map which provides per-file Go version information. * go/types: The new helper method PkgNameOf returns the local package name for the given import declaration. * go/types: The implementation of SizesFor has been adjusted to compute the same type sizes as the compiler when the compiler argument for SizesFor is "gc". The default Sizes implementation used by the type checker is now types.SizesFor("gc", "amd64"). * go/types: The start position (Pos) of the lexical environment block (Scope) that represents a function body has changed: it used to start at the opening curly brace of the function body, but now starts at the function's func token. * html/template: Javascript template literals may now contain Go template actions, and parsing a template containing one will no longer return ErrJSTemplate. Similarly the GODEBUG setting jstmpllitinterp no longer has any effect. * io: The new SectionReader.Outer method returns the ReaderAt, offset, and size passed to NewSectionReader. * log/slog: The new SetLogLoggerLevel function controls the level for the bridge between the `slog` and `log` packages. It sets the minimum level for calls to the top-level `slog` logging functions, and it sets the level for calls to `log.Logger` that go through `slog`. * math/big: The new method Rat.FloatPrec computes the number of fractional decimal digits required to represent a rational number accurately as a floating-point number, and whether accurate decimal representation is possible in the first place. * net: When io.Copy copies from a TCPConn to a UnixConn, it will now use Linux's splice(2) system call if possible, using the new method TCPConn.WriteTo. * net: The Go DNS Resolver, used when building with "-tags=netgo", now searches for a matching name in the Windows hosts file, located at %SystemRoot%\System32\drivers\etc\hosts, before making a DNS query. * net/http: The new functions ServeFileFS, FileServerFS, and NewFileTransportFS are versions of the existing ServeFile, FileServer, and NewFileTransport, operating on an fs.FS. * net/http: The HTTP server and client now reject requests and responses containing an invalid empty Content-Length header. The previous behavior may be restored by setting GODEBUG field httplaxcontentlength=1. * net/http: The new method Request.PathValue returns path wildcard values from a request and the new method Request.SetPathValue sets path wildcard values on a request. * net/http/cgi: When executing a CGI process, the PATH_INFO variable is now always set to the empty string or a value starting with a / character, as required by RFC 3875. It was previously possible for some combinations of Handler.Root and request URL to violate this requirement. * net/netip: The new AddrPort.Compare method compares two AddrPorts. * os: On Windows, the Stat function now follows all reparse points that link to another named entity in the system. It was previously only following IO_REPARSE_TAG_SYMLINK and IO_REPARSE_TAG_MOUNT_POINT reparse points. * os: On Windows, passing O_SYNC to OpenFile now causes write operations to go directly to disk, equivalent to O_SYNC on Unix platforms. * os: On Windows, the ReadDir, File.ReadDir, File.Readdir, and File.Readdirnames functions now read directory entries in batches to reduce the number of system calls, improving performance up to 30%. * os: When io.Copy copies from a File to a net.UnixConn, it will now use Linux's sendfile(2) system call if possible, using the new method File.WriteTo. * os/exec: On Windows, LookPath now ignores empty entries in %PATH%, and returns ErrNotFound (instead of ErrNotExist) if no executable file extension is found to resolve an otherwise-unambiguous name. * os/exec: On Windows, Command and Cmd.Start no longer call LookPath if the path to the executable is already absolute and has an executable file extension. In addition, Cmd.Start no longer writes the resolved extension back to the Path field, so it is now safe to call the String method concurrently with a call to Start. * reflect: The Value.IsZero method will now return true for a floating-point or complex negative zero, and will return true for a struct value if a blank field (a field named _) somehow has a non-zero value. These changes make IsZero consistent with comparing a value to zero using the language == operator. * reflect: The PtrTo function is deprecated, in favor of PointerTo. * reflect: The new function TypeFor returns the Type that represents the type argument T. Previously, to get the reflect.Type value for a type, one had to use reflect.TypeOf((*T)(nil)).Elem(). This may now be written as reflect.TypeForT. * runtime/metrics: Four new histogram metrics /sched/pauses/stopping/gc:seconds, /sched/pauses/stopping/other:seconds, /sched/pauses/total/gc:seconds, and /sched/pauses/total/other:seconds provide additional details about stop-the-world pauses. The "stopping" metrics report the time taken from deciding to stop the world until all goroutines are stopped. The "total" metrics report the time taken from deciding to stop the world until it is started again. * runtime/metrics: The /gc/pauses:seconds metric is deprecated, as it is equivalent to the new /sched/pauses/total/gc:seconds metric. * runtime/metrics: /sync/mutex/wait/total:seconds now includes contention on runtime-internal locks in addition to sync.Mutex and sync.RWMutex. * runtime/pprof: Mutex profiles now scale contention by the number of goroutines blocked on the mutex. This provides a more accurate representation of the degree to which a mutex is a bottleneck in a Go program. For instance, if 100 goroutines are blocked on a mutex for 10 milliseconds, a mutex profile will now record 1 second of delay instead of 10 milliseconds of delay. * runtime/pprof: Mutex profiles also now include contention on runtime- internal locks in addition to sync.Mutex and sync.RWMutex. Contention on runtime-internal locks is always reported at runtime._LostContendedRuntimeLock. A future release will add complete stack traces in these cases. * runtime/pprof: CPU profiles on Darwin platforms now contain the process's memory map, enabling the disassembly view in the pprof tool. * runtime/trace: The execution tracer has been completely overhauled in this release, resolving several long-standing issues and paving the way for new use-cases for execution traces. * runtime/trace: Execution traces now use the operating system's clock on most platforms (Windows excluded) so it is possible to correlate them with traces produced by lower-level components. Execution traces no longer depend on the reliability of the platform's clock to produce a correct trace. Execution traces are now partitioned regularly on-the-fly and as a result may be processed in a streamable way. Execution traces now contain complete durations for all system calls. Execution traces now contain information about the operating system threads that goroutines executed on. The latency impact of starting and stopping execution traces has been dramatically reduced. Execution traces may now begin or end during the garbage collection mark phase. * runtime/trace: To allow Go developers to take advantage of these improvements, an experimental trace reading package is available at golang.org/x/exp/trace. Note that this package only works on traces produced by programs built with go1.22 at the moment. Please try out the package and provide feedback on the corresponding proposal issue. * runtime/trace: If you experience any issues with the new execution tracer implementation, you may switch back to the old implementation by building your Go program with GOEXPERIMENT=noexectracer2. If you do, please file an issue, otherwise this option will be removed in a future release. * slices: The new function Concat concatenates multiple slices. * slices: Functions that shrink the size of a slice (Delete, DeleteFunc, Compact, CompactFunc, and Replace) now zero the elements between the new length and the old length. * slices: Insert now always panics if the argument i is out of range. Previously it did not panic in this situation if there were no elements to be inserted. * syscall: The syscall package has been frozen since Go 1.4 and was marked as deprecated in Go 1.11, causing many editors to warn about any use of the package. However, some non-deprecated functionality requires use of the syscall package, such as the os/exec.Cmd.SysProcAttr field. To avoid unnecessary complaints on such code, the syscall package is no longer marked as deprecated. The package remains frozen to most new functionality, and new code remains encouraged to use golang.org/x/sys/unix or golang.org/x/sys/windows where possible. * syscall: On Linux, the new SysProcAttr.PidFD field allows obtaining a PID FD when starting a child process via StartProcess or os/exec. * syscall: On Windows, passing O_SYNC to Open now causes write operations to go directly to disk, equivalent to O_SYNC on Unix platforms. * testing/slogtest: The new Run function uses sub-tests to run test cases, providing finer-grained control. * Ports: Darwin: On macOS on 64-bit x86 architecture (the darwin/amd64 port), the Go toolchain now generates position-independent executables (PIE) by default. Non-PIE binaries can be generated by specifying the -buildmode=exe build flag. On 64-bit ARM-based macOS (the darwin/arm64 port), the Go toolchain already generates PIE by default. go1.22 is the last release that will run on macOS 10.15 Catalina. Go 1.23 will require macOS 11 Big Sur or later. * Ports: Arm: The GOARM environment variable now allows you to select whether to use software or hardware floating point. Previously, valid GOARM values were 5, 6, or 7. Now those same values can be optionally followed by ,softfloat or ,hardfloat to select the floating-point implementation. This new option defaults to softfloat for version 5 and hardfloat for versions 6 and 7. * Ports: Loong64: The loong64 port now supports passing function arguments and results using registers. The linux/loong64 port now supports the address sanitizer, memory sanitizer, new-style linker relocations, and the plugin build mode. ## Patch Instructions: To install this SUSE update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
