PROJECT DETAILS
---------------
OBS: https://build.opensuse.org/project/show?project=devel:languages:go
Maintainers: Sascha Peilicke (saschpe),
Graham Anderson (andtecheu)
Wiki: http://en.opensuse.org/Go
http://en.opensuse.org/openSUSE:Packaging_Go
GENERAL NOTES
-------------
Go toolchain environmental variables are configured via go.sh, which is
installed to /etc/profile.d/go.sh
Packaging guidelines and an RPM spec file recipe for packaging third party Go
libraries can be found on the openSUSE wiki:
http://en.opensuse.org/openSUSE:Packaging_Go
The openSUSE go package uses the standard Go distribution toolchain, with a
a small patchset to modify a few of the toolchain commands to suit our
environment and packaging needs.
This means that many of the standard go toolchain commands are not inside a
users PATH, but rather are invoked and used via the "go" command. Should you
wish to script or manually use the commands, the install location on a 64 bit
system is /usr/lib64/go/pkg/tool/linux_amd64
The "go" tool, the "godoc" document server are inside a users PATH.
We currently don't support the gccgo implementation, this is not for
any other reason than contributer and maintainer time constraints.
GO DOCUMENTATION
----------------
As of yet, there are no man pages for the standard Go distribution toolchain,
please see the documentation provided by the "godoc" command. Man pages are
slated to be included in the release in future.
One of the diffs from the maintained patchset adds the distro specific doc and
source file locations of the *-doc RPM packages to the virtual filesystem of
the "godoc" documentation server. That is to say, as long as packages follow
the Go packaging guidelines, API and other documentation should always be
available via the godoc server if the packages "doc" RPM is installed.
PACKAGE INSTALL LOCATIONS
-------------------------
Go standard library packages are installed to a location in $GOROOT, which is
defined as /usr/lib64/go on 64bit systems.
Third party package binaries are installed to the default system wide
$GOPATH entry. On 64bit systems the location /usr/lib64/go/contrib is used.
This is specified in the macros.go RPM macro definition file that is part of
the main Go package and is used for packaging most third party Go libraries.
The reasons binary packages are installed to a GOPATH entry instead of GOROOT
are mainly to do with how the Go toolchain prioritises and behaves with
packages installed to the same location as the Go std library.
By installing third party packages to a system-wide GOPATH entry location,
we can ensure that no packages clobber the standard library namespace or file
tree. Additionally we can support binary only packages, which as of Go 1.1
will only be supported outside of the $GOROOT.
There are additional benefits to this location; such as allowing users and
developers to prioritise linking from their own user defined GOPATH, which
defaults to $HOME/go configured via /etc/profile.d/go.sh config. This has
particular benefit for development workflows.
For Go 1.1 and beyond, building and linking with binary only pacakges will
only be supported with the following caveat. Package source code must not
exist in the same GOPATH segment as the binary package .a archive file.
If both the binary archive (.a) and the package source are installed to the
same GOPATH segment, then the "go build" or "go install" command will
prioritise building the software using package sources before using package
binary archives. A side effect of this is that is actually possible to have
source code only third party packages.
To summarise the priority of binary package linking and building:
1. Any source files or binary packages in $GOROOT are considered first. Any
binary packages in $GOROOT that are considered "stale" by the build tools
are ignored in favour of the package source.
2. $GOPATH is considered next for import statements. GOPATH is a colon
delimited list of paths. GOPATH segments are examined by the build tools
in a FIFO manner, left to right.
Both a system wide and a user GOPATH segment are configured by default,
the user GOPATH segment takes priority over the system segment to allow
flexibility for development workflows.
The default user GOPATH is:
GOPATH=$HOME/go:$GOROOT/contrib
The default root user GOPATH is:
GOPATH=$GOROOT/contrib
3. For Go < 1.1, If both the source and binary archive is available for a
package import in the same GOPATH segment, the binary archive will take
precedence and will be linked during compilation.
For Go >= 1.1 If the package source is avaiable in the GOPATH segment, it
will always be used in preference to the binary

From 5c55ac9bf1e5f779220294c843526536605f42ab Mon Sep 17 00:00:00 2001
From: Damien Neil <dneil@google.com>
Date: Wed, 25 Jan 2023 09:27:01 -0800
Subject: [PATCH] [release-branch.go1.19] mime/multipart: limit memory/inode
consumption of ReadForm
Reader.ReadForm is documented as storing "up to maxMemory bytes + 10MB"
in memory. Parsed forms can consume substantially more memory than
this limit, since ReadForm does not account for map entry overhead
and MIME headers.
In addition, while the amount of disk memory consumed by ReadForm can
be constrained by limiting the size of the parsed input, ReadForm will
create one temporary file per form part stored on disk, potentially
consuming a large number of inodes.
Update ReadForm's memory accounting to include part names,
MIME headers, and map entry overhead.
Update ReadForm to store all on-disk file parts in a single
temporary file.
Files returned by FileHeader.Open are documented as having a concrete
type of *os.File when a file is stored on disk. The change to use a
single temporary file for all parts means that this is no longer the
case when a form contains more than a single file part stored on disk.
The previous behavior of storing each file part in a separate disk
file may be reenabled with GODEBUG=multipartfiles=distinct.
Update Reader.NextPart and Reader.NextRawPart to set a 10MiB cap
on the size of MIME headers.
Thanks to Jakob Ackermann (@das7pad) for reporting this issue.

Fri Apr 14 23:20:06 UTC 2023 - Jeff Kowalczyk <jkowalczyk@suse.com>
- Add subpackage go1.x-libstd for compiled shared object libstd.so.
Refs jsc#PED-1962
* Main go1.x package included libstd.so in previous versions
* Split libstd.so into subpackage that can be installed standalone
* Continues the slimming down of main go1.x package by 40 Mb
* Experimental and not recommended for general use, Go currently has no ABI
* Upstream Go has not committed to support buildmode=shared long-term
* Do not use in packaging, build static single binaries (the default)
* Upstream Go go1.x binary releases do not include libstd.so
* go1.x Suggests go1.x-libstd so not installed by default Recommends
* go1.x-libstd does not Require: go1.x so can install standalone
* Provides go-libstd unversioned package name
* Fix build step -buildmode=shared std to omit -linkshared
- Packaging improvements:
* go1.x Suggests go1.x-doc so not installed by default Recommends
* Use Group: Development/Languages/Go instead of Other
-------------------------------------------------------------------
Fri Apr 14 23:06:51 UTC 2023 - Jeff Kowalczyk <jkowalczyk@suse.com>
- Improvements to go1.x packaging spec:
* On Tumbleweed bootstrap with current default gcc13 and gccgo118
* On SLE-12 aarch64 ppc64le ppc64 remove overrides to bootstrap
using go1.x package (%bcond_without gccgo). This is no longer
needed on current SLE-12:Update and removing will consolidate
the build configurations used.
* Change source URLs to go.dev as per Go upstream
* On x86_64 export GOAMD64=v1 as per the current baseline.
At this time forgo GOAMD64=v3 option for x86_64_v3 support.
* On x86_64 %define go_amd64=v1 as current instruction baseline

- go1.18 (released 2022-03-15) is a major release of Go.
go1.18.x minor releases will be provided through February 2023.
https://github.com/golang/go/wiki/Go-Release-Cycle
Go 1.18 is a significant release, including changes to the
language, implementation of the toolchain, runtime, and
libraries. Go 1.18 arrives seven months after Go 1.17. 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#1193742 go1.18 release tracking
* See release notes https://golang.org/doc/go1.18. Excerpts
relevant to OBS environment and for SUSE/openSUSE follow:
* Go 1.18 includes an implementation of generic features as
described by the Type Parameters Proposal. This includes major
but fully backward-compatible changes to the language.
* The Go 1.18 compiler now correctly reports declared but not
used errors for variables that are set inside a function
literal but are never used. Before Go 1.18, the compiler did
not report an error in such cases. This fixes long-outstanding
compiler issue go#8560.
* The Go 1.18 compiler now reports an overflow when passing a
rune constant expression such as '1' << 32 as an argument to
the predeclared functions print and println, consistent with
the behavior of user-defined functions. Before Go 1.18, the
compiler did not report an error in such cases but silently
accepted such constant arguments if they fit into an
int64. Since go vet always pointed out this error, the number
of affected programs is likely very small.
* AMD64: Go 1.18 introduces the new GOAMD64 environment variable,
which selects at compile time a minimum target version of the
AMD64 architecture. Allowed values are v1, v2, v3, or v4. Each
higher level requires, and takes advantage of, additional
processor features. A detailed description can be found
here. The GOAMD64 environment variable defaults to v1.
* RISC-V: The 64-bit RISC-V architecture on Linux (the
linux/riscv64 port) now supports the c-archive and c-shared
build modes.
* Linux: Go 1.18 requires Linux kernel version 2.6.32 or later.
* Fuzzing: Go 1.18 includes an implementation of fuzzing as
described by the fuzzing proposal. See the fuzzing landing page
to get started. Please be aware that fuzzing can consume a lot
of memory and may impact your machine’s performance while it
runs.
* go get: go get no longer builds or installs packages in
module-aware mode. go get is now dedicated to adjusting
dependencies in go.mod. Effectively, the -d flag is always
enabled. To install the latest version of an executable outside
the context of the current module, use go install
example.com/cmd@latest. Any version query may be used instead
of latest. This form of go install was added in Go 1.16, so
projects supporting older versions may need to provide install
instructions for both go install and go get. go get now reports
an error when used outside a module, since there is no go.mod
file to update. In GOPATH mode (with GO111MODULE=off), go get
still builds and installs packages, as before.
* Automatic go.mod and go.sum updates: The go mod graph, go mod
vendor, go mod verify, and go mod why subcommands no longer
automatically update the go.mod and go.sum files. (Those files
can be updated explicitly using go get, go mod tidy, or go mod
download.)
* go version: The go command now embeds version control
information in binaries. It includes the currently checked-out
revision, commit time, and a flag indicating whether edited or
untracked files are present. Version control information is
embedded if the go command is invoked in a directory within a
Git, Mercurial, Fossil, or Bazaar repository, and the main
package and its containing main module are in the same
repository. This information may be omitted using the flag
-buildvcs=false. Additionally, the go command embeds
information about the build, including build and tool tags (set
with -tags), compiler, assembler, and linker flags (like
-gcflags), whether cgo was enabled, and if it was, the values
of the cgo environment variables (like CGO_CFLAGS). Both VCS
and build information may be read together with module
information using go version -m file or
runtime/debug.ReadBuildInfo (for the currently running binary)
or the new debug/buildinfo package. The underlying data format
of the embedded build information can change with new go
releases, so an older version of go may not handle the build
information produced with a newer version of go. To read the
version information from a binary built with go 1.18, use the
go version command and the debug/buildinfo package from go
1.18+.
* go mod download: If the main module's go.mod file specifies go
1.17 or higher, go mod download without arguments now downloads
source code for only the modules explicitly required in the
main module's go.mod file. (In a go 1.17 or higher module, that
set already includes all dependencies needed to build the
packages and tests in the main module.) To also download source
code for transitive dependencies, use go mod download all.
* go mod vendor: The go mod vendor subcommand now supports a -o
flag to set the output directory. (Other go commands still read
from the vendor directory at the module root when loading
packages with -mod=vendor, so the main use for this flag is for
third-party tools that need to collect package source code.)
* go mod tidy: The go mod tidy command now retains additional
checksums in the go.sum file for modules whose source code is
needed to verify that each imported package is provided by only
one module in the build list. Because this condition is rare
and failure to apply it results in a build error, this change
is not conditioned on the go version in the main module's
go.mod file.
* go work: The go command now supports a "Workspace" mode. If a
go.work file is found in the working directory or a parent
directory, or one is specified using the GOWORK environment
variable, it will put the go command into workspace mode. In
workspace mode, the go.work file will be used to determine the
set of main modules used as the roots for module resolution,
instead of using the normally-found go.mod file to specify the
single main module. For more information see the go work
documentation.
* go build -asan: The go build command and related commands now
support an -asan flag that enables interoperation with C (or
C++) code compiled with the address sanitizer (C compiler
option -fsanitize=address).
* //go:build lines: Go 1.17 introduced //go:build lines as a more
readable way to write build constraints, instead of // +build
lines. As of Go 1.17, gofmt adds //go:build lines to match
existing +build lines and keeps them in sync, while go vet
diagnoses when they are out of sync. Since the release of Go
1.18 marks the end of support for Go 1.16, all supported
versions of Go now understand //go:build lines. In Go 1.18, go
fix now removes the now-obsolete // +build lines in modules
declaring go 1.17 or later in their go.mod files. For more
information, see https://go.dev/design/draft-gobuild.
* go vet: The vet tool is updated to support generic code. In
most cases, it reports an error in generic code whenever it
would report an error in the equivalent non-generic code after
substituting for type parameters with a type from their type
set.
* go vet: The cmd/vet checkers copylock, printf, sortslice,
testinggoroutine, and tests have all had moderate precision
improvements to handle additional code patterns. This may lead
to newly reported errors in existing packages.
* Runtime: The garbage collector now includes non-heap sources of
garbage collector work (e.g., stack scanning) when determining
how frequently to run. As a result, garbage collector overhead
is more predictable when these sources are significant. For
most applications these changes will be negligible; however,
some Go applications may now use less memory and spend more
time on garbage collection, or vice versa, than before. The
intended workaround is to tweak GOGC where necessary. The
runtime now returns memory to the operating system more
efficiently and has been tuned to work more aggressively as a
result.
* Compiler: Go 1.17 implemented a new way of passing function
arguments and results using registers instead of the stack on
64-bit x86 architecture on selected operating systems. Go 1.18
expands the supported platforms to include 64-bit ARM
(GOARCH=arm64), big- and little-endian 64-bit PowerPC
(GOARCH=ppc64, ppc64le), as well as 64-bit x86 architecture
(GOARCH=amd64) on all operating systems. On 64-bit ARM and
64-bit PowerPC systems, benchmarking shows typical performance
improvements of 10% or more. As mentioned in the Go 1.17
release notes, this change does not affect the functionality of
any safe Go code and is designed to have no impact on most
assembly code. See the Go 1.17 release notes for more details.
* Compiler: The compiler now can inline functions that contain
range loops or labeled for loops.
* Compiler: The new -asan compiler option supports the new go
command -asan option.
* Compiler: Because the compiler's type checker was replaced in
its entirety to support generics, some error messages now may
use different wording than before. In some cases, pre-Go 1.18
error messages provided more detail or were phrased in a more
helpful way. We intend to address these cases in Go
1.19. Because of changes in the compiler related to supporting
generics, the Go 1.18 compile speed can be roughly 15% slower
than the Go 1.17 compile speed. The execution time of the
compiled code is not affected. We intend to improve the speed
of the compiler in Go 1.19.
* Linker: The linker emits far fewer relocations. As a result,
most codebases will link faster, require less memory to link,
and generate smaller binaries. Tools that process Go binaries
should use Go 1.18's debug/gosym package to transparently
handle both old and new binaries.
* Linker: The new -asan linker option supports the new go command
-asan option.
* 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 now
looks first for $HOME/go1.17 or $HOME/sdk/go1.17 before falling
back to $HOME/go1.4. We intend for Go 1.19 to require Go 1.17
or later for bootstrap, and this change should make the
transition smoother. For more details, see go#44505.
* The new debug/buildinfo package provides access to module
versions, version control information, and build flags embedded
in executable files built by the go command. The same
information is also available via runtime/debug.ReadBuildInfo
for the currently running binary and via go version -m on the
command line.
* The new net/netip package defines a new IP address type,
Addr. Compared to the existing net.IP type, the netip.Addr type
takes less memory, is immutable, and is comparable so it
supports == and can be used as a map key.
* TLS 1.0 and 1.1 disabled by default client-side: If
Config.MinVersion is not set, it now defaults to TLS 1.2 for
client connections. Any safely up-to-date server is expected to
support TLS 1.2, and browsers have required it since 2020. TLS
1.0 and 1.1 are still supported by setting Config.MinVersion to
VersionTLS10. The server-side default is unchanged at TLS
1.0. The default can be temporarily reverted to TLS 1.0 by
setting the GODEBUG=tls10default=1 environment variable. This
option will be removed in Go 1.19.
* Rejecting SHA-1 certificates: crypto/x509 will now reject
certificates signed with the SHA-1 hash function. This doesn't
apply to self-signed root certificates. Practical attacks
against SHA-1 have been demonstrated since 2017 and publicly
trusted Certificate Authorities have not issued SHA-1
certificates since 2015. This can be temporarily reverted by
setting the GODEBUG=x509sha1=1 environment variable. This
option will be removed in Go 1.19.
* crypto/elliptic The P224, P384, and P521 curve implementations
are now all backed by code generated by the addchain and
fiat-crypto projects, the latter of which is based on a
formally-verified model of the arithmetic operations. They now
use safer complete formulas and internal APIs. P-224 and P-384
are now approximately four times faster. All specific curve
implementations are now constant-time. Operating on invalid
curve points (those for which the IsOnCurve method returns
false, and which are never returned by Unmarshal or a Curve
method operating on a valid point) has always been undefined
behavior, can lead to key recovery attacks, and is now
unsupported by the new backend. If an invalid point is supplied
to a P224, P384, or P521 method, that method will now return a
random point. The behavior might change to an explicit panic in
a future release.
* crypto/tls: The new Conn.NetConn method allows access to the
underlying net.Conn.
* crypto/x509: Certificate.Verify now uses platform APIs to
verify certificate validity on macOS and iOS when it is called
with a nil VerifyOpts.Roots or when using the root pool
returned from SystemCertPool. SystemCertPool is now available
on Windows.
* crypto/x509: CertPool.Subjects is deprecated. On Windows,
macOS, and iOS the CertPool returned by SystemCertPool will
return a pool which does not include system roots in the slice
returned by Subjects, as a static list can't appropriately
represent the platform policies and might not be available at
all from the platform APIs.
* crypto/x509: Support for signing certificates using signature
algorithms that depend on the MD5 and SHA-1 hashes (MD5WithRSA,
SHA1WithRSA, and ECDSAWithSHA1) may be removed in Go 1.19.
* net/http: When looking up a domain name containing non-ASCII
characters, the Unicode-to-ASCII conversion is now done in
accordance with Nontransitional Processing as defined in the
Unicode IDNA Compatibility Processing standard (UTS #46). The
interpretation of four distinct runes are changed: ß, ς,
zero-width joiner U+200D, and zero-width non-joiner
U+200C. Nontransitional Processing is consistent with most
applications and web browsers.
* os/user: User.GroupIds now uses a Go native implementation when
cgo is not available.
* runtime/debug: The BuildInfo struct has two new fields,
containing additional information about how the binary was
built: GoVersion holds the version of Go used to build the
binary. Settings is a slice of BuildSettings structs holding
key/value pairs describing the build.
* runtime/pprof: The CPU profiler now uses per-thread timers on
Linux. This increases the maximum CPU usage that a profile can
observe, and reduces some forms of bias.
* syscall: The new function SyscallN has been introduced for
Windows, allowing for calls with arbitrary number of arguments.
As a result, Syscall, Syscall6, Syscall9, Syscall12, Syscall15,
and Syscall18 are deprecated in favor of SyscallN.
