I recently reviewed some code that did time calculations using
`time.UnixMicro(0).UTC()`. I commented that because time calculations
are independent of the location, they should drop the `.UTC()`, and they
replied that it made their tests fail.
I looked into it and eventually discovered it was because they were
using AddDate. Dramatically simplified, their code did something like:
orig := time.Date(2013, time.March, 23, 12, 00, 0, 0, time.UTC)
want := time.Date(2013, time.March, 23, 0, 0, 0, 0, time.UTC)
epoch := time.UnixMicro(0)
days := int(orig.Sub(epoch).Hours() / 24)
got := epoch.AddDate(0, 0, days)
if !got.Equal(want) {
t.Errorf("ay caramba: %v vs %v", got.UTC(), want.UTC())
}
The issue is that their tests run in Pacific time, which is currently
PST (UTC-8) but was PDT (UTC-7) in January 1970.
It turns out they were implementing some business policy that really
cares abut calendar days so AddDate is correct, but it's certainly a bit
confusing!
The idea with this change is to remove the risk that readers make a
false shortcut in their mind: "Locations do not affect time
calculations". To do this we remove some text from the core time.Time
doc and shift it to the areas of the library that deal with these
intrinsically confusing operations.

[[ is a compound command part of the language with structure,
whereas [ is simply a standard program with string arguments.
The former has a few significant advantages over the latter:
* Better syntax, e.g. && and || rather than -a and -o,
as well as == rather than = for comparisons
* No need for fork+exec to evaluate each conditional
* Forgetting the closing token is an early parse error
The only advantage of [ over [[ is that [[ is Bash syntax,
whereas [ and "test" are portable POSIX Shell utilities.
However, this is a Bash script, so that is not a concern.

CL 531516 converted origRlimitNofile from an atomic.Value to
atomic.Pointer[Rlimit]. i.e., it changed from storing a value to storing
a pointer.
After storing a pointer to lim, the remainder of this function
immediately modifies it, thus mutating the value pointer to by
origRlimitNofile (and thus defeating the point of origRlimitNofile).
This broke the android-amd64-emu builder because it is (apparently) the
only builder where the original RLIMIT_NOFILE Cur != Max.
TestRlimitRestored is skipped on every other builder.

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.

with enough scheduling delay we can manage to trip the race detector
on a call to Logf after the test function has returned.
Updates #38370.

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.

CL 525556 started using timeRE regexp to match time output from JSON
handler, and relaxed it to allow arbitrary (rather than fixed 3 digit)
precision.
What it missed is in JSON handler the fractional part is omitted
entirely (together with the decimal dot) when the nanoseconds field is
0.
As a result, there are occasional CI failures in js/wasm (which, I guess,
has better chances to return zero nanoseconds).
To fix the flaky test, let's use two different regular expressions,
tailored to text and JSON.

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.
