This change undoes the restrictions added in CL 482079, which added a
blanket ban on using actions within JS template literal strings, and
adds logic to support actions while properly applies contextual escaping
based on the correct context within the literal.
Since template literals can contain both normal strings, and nested JS
contexts, logic is required to properly track those context switches
during parsing.
ErrJsTmplLit is deprecated, and the GODEBUG flag jstmpllitinterp no

Previously, the built-in handlers assumed a group was empty if and
only if it had no attributes. But a ReplaceAttr function that
returned an empty Attr could produce an empty group even if the group
had attrs prior to replacement.
The obvious solution, doing the replacement first and then checking,
would require allocating storage to hold the replaced Attrs. Instead,
we write to the buffer, and if no attributes were written, we back up
to before the group name.

This patch fixes some problems with how "go test -cover" was handling
tests involving A) multiple package tests and B) multiple packages
matched by "-coverpkg". In such scenarios the expectation is that the
percent statements covered metric for each package needs to be
relative to all statements in all packages matched by the -coverpkg
arg (this aspect of the reporting here was broken as part of
GOEXPERIMENT=coverageredesign).
The new scheme works as follows. If -coverpkg is in effect and is
matching multiple packages, and we have multiple test targets, then:
- each time a package is built for coverage, capture a meta-data
file fragment corresponding to just the meta-data for that package.
- create a new "writeCoverMeta" action, and interpose it between the
build actions for the covered packages and the run actions. The
"writeCoverMeta" action at runtime will emit a file
"metafiles.txt" containing a table mapping each covered package
(by import path) to its corresponding meta-data file fragment.
- pass in the "metafiles.txt" file to each run action, so that
when the test finishes running it will have an accurate picture
of _all_ covered packages, permitting it to calculate the correct
percentage.
Concrete example: suppose we have a top level directory with three
package subdirs, "a", "b", and "c", and from the top level, a user
runs "go test -coverpkg=./... ./...". This will result in (roughly)
the following action graph:
build("a") build("b") build("c")
| | |
link("a.test") link("b.test") link("c.test")
| | |
run("a.test") run("b.test") run("c.test")
| | |
print print print
With the new scheme, the action graph is augmented with a
writeCoverMeta action and additional dependence edges to form
build("a") build("b") build("c")
| \ / | / |
| v v | / |
| writecovmeta<-|-------------+ |
| ||| | |
| ||\ | |
link("a.test")/\ \ link("b.test") link("c.test")
| / \ +-|--------------+ |
| / \ | \ |
| v v | v |
run("a.test") run("b.test") run("c.test")
| | |
print print print
A note on init functions: prior to GOEXPERIMENT=coverageredesign
the "-coverpkg=..." flag was implemented by force-importing
all packages matched by "-coverpkg" into each instrumented package.
This meant that for the example above, when executing "a.test",
the init function for package "c" would fire even if package "a"
did not ordinarily import package "c". The new implementation
does not do this sort of forced importing, meaning that the coverage
percentages can be slightly different between 1.21 and 1.19 if
there are user-written init funcs.

Updates #24570.

This patch improves the way the go command handles coverage testing
of packages that have functions but don't have any test files. Up to
this point if you ran "go test -cover" on such a package, you would
see:
? mymod/mypack [no test files]
While "no test files" is true, it is also very unhelpful; if the
package contains functions, it would be better instead to capture the
fact that these functions are not executed when "go test -cover" is
run on the package.
With this patch, for the same no-test package "go test -cover" will
output:
mymod/mypack coverage: 0.0% of statements
The inclusion of such packages in coverage reporting also extends to
"-coverprofile" as well (we'll see entries for the "mypack" functions
in this case.
Note that if a package has no functions at all, then we'll still fall
back to reporting "no test files" in this case; it doesn't make sense
to report "0.0% statements covered" if there are no statements.

This CL is a roll-forward (tweaked slightly) of CL 467715, which
turned on text section splitting for GOARCH=arm. The intent is to
avoid recurrent problems with external linking where there is a
disagreement between the Go linker and the external linker over
whether a given branch will reach. In the past our approach has been
to tweak the reachability calculations slightly to try to work around
potential linker problems, but this hasn't proven to be very robust;
section splitting seems to offer a better long term fix.

In CL 197062, many errors related to go.sum were changed from base.Fatal
to error returns. The malformed go.sum error was lost in the process.
Currently, when go encounters a malformed go.sum file, go will read the
well-formed part of the file and then silently ignore the rest.
The motivation behind moving away from base.Fatal was to make the errors
show up in -json output. Simply propagating the malformed go.sum error
would not achieve this:
- For an argument-less 'go mod download -json' with a go>=1.17 module,
a malformed go.sum causes an error during LoadModGraph already, before
go ever starts downloading modules and printing their JSON.
- In other cases, a malformed go.sum would be reported as Error for one
of the modules (presumably the one which gets downloaded first) but
none of the others.
- In either case, 'go mod download' manages to download enough data to
succeed on a re-run, making the error look intermittent.
Switch the error back to a Fatal one, but give 'go mod tidy' an
exception to let it fix broken go.sum files.

What it missed is in JSON handler the fractional part is omitted

As a result, there are occasional CI failures in js/wasm (which, I guess,

In CL 475375 the Go command started to generate the "preferlinkext"
token file for "strange/dangerous" compiler flags. This serves as a hint
to the Go linker whether to call the external linker or not.
Permit compiler flags used by bazel and bazelbuild/rules_go during
compilation of cgo code to not prefer external linking. This restores
the behavior of previous versions of Go.
As a side effect, it also allows these flags to appear
in #cgo directives in source code. We don't know of any cases
where that is actually useful, but it appears to be harmless
and simplifies the implementation of the internal linking change.
Fixes#60865

When parsing patterns and matching, split the path into segments at
slashes, then unescape each segment.
This behaves as most people would expect:
- The pattern "/%61" matches the paths "/a" and "/%61".
- The pattern "/%7B" matches the path "/{". (If we did not unescape
patterns, there would be no way to write that pattern: because "/{"
is a parse error because it is an invalid wildcard.)
- The pattern "/user/{u}" matches "/user/john%2Fdoe" with u set to
"john/doe".
- The unexpected redirections of #21955 will not occur.
A later CL will restore the old behavior behind a GODEBUG setting.
Updates #61410.
Fixes#21955.

This adds some rules to recognize MOVDaddr in those cases where
it is just adding 0 to a ptr value. Instead the ptr value can just
be used.

When running crypto/tls tests with GOEXPERIMENT=boringcrypto, some
tests are embedded with unreadable hexadecimal values:
=== RUN TestBoringServerSignatureAndHash/5053...3536
This corresponds to a string representation of SignatureScheme as it
implements fmt.Stringer. With this change, the above will be printed
as:
=== RUN TestBoringServerSignatureAndHash/PSSWithSHA256

I found the documentation for Pinner itself to contain too little information.
Rewrite it to give a summary and redirect to the relevant methods.
Also reformat the ragged comment for Pin.

The https://go.dev/security is about: "This page provides
resources for Go developers to improve security for their
projects.", https://go.dev/security/policy is about Go Security Policy.
go.dev/security links to go.dev/security/policy,
but I think it is better to link directly to go.dev/security/policy
in this case.

When reviewing https://go-review.googlesource.com/c/go/+/522435,
Cherry Mui cherryyz@google.com noticed that the implementation of
StructOf was broken, and produced junk if an interface was embedded
into a struct. For example, StructOf messed up the calling convention
for methods of the embedded interface:
> The main problem is that the method wrappers created by reflect.MakeFunc
> expects to be called with a closure calling convention, with a closure
> context passed in the context register. But methods are called with
> a different calling convention, without setting the closure register,
> because (besides this case) all methods are top level functions.
> So there is no way to pass that makefunc closure context.
It is curious that StructOf did not break in go 1.17 which introduced
the regabi. I've tried to run the following example program, and it
fails even in 1.7 which introduced StructOf.
As the embedding of interfaces has been broken since forever,
let us not perpetuate the complexity that this feature brings,
and just remove the support for embedding altogether.
The test program:
package main
import (
"fmt"
"reflect"
)
type I interface {
F()
}
type T int
func (t T) F() { println(t) }
func main() {
var i I
t := reflect.StructOf([]reflect.StructField{
{
Anonymous: true,
Name: "I",
Type: reflect.TypeOf(&i).Elem(),
},
})
v := reflect.New(t).Elem()
v.Field(0).Set(reflect.ValueOf(T(42)))
fmt.Println(v)
v.Interface().(interface{ F() }).F() // fatal error
}
