We have an optimization for this specific pattern, but it's really just
a hack. With the addition of unsafe.Add in Go 1.17 we can directly
specify the intent instead and eventually remove this special case.
The code is also easier to read.
Unfortunately the calling convention for variadic functions is different from
the calling convention of regular functions on darwin/arm64, and open happens
to be such a variadic function. The syscall package treated it like a regular
function, which resulted in buggy behavior.
This fix introduces a wrapper function. This is the cleanest change I could
come up with.
Go 1.19 started reformatting code in a way that makes it more obvious
how it will be rendered on pkg.go.dev. It gets it almost right, but not
entirely. Therefore, I had to modify some of the comments so that they
are formatted correctly.
Evidently when you read from pipes in Go, you have to adjust your slice length to reflect the number of bytes read.
Verified upstream behaves the same way.
Grepped straight out of the appropriate signal.h, with order preserved.
Makes 1.18 tests happier.
See comment on discrepancy for SIGCHLD. Since wasi doesn't really support signals, this may not matter.
Makes 1.18 tests a little happier.
Works around this error:
$ make test GOTESTFLAGS="-run TestTest/EmulatedCortexM3/Pass"
...
main_test.go:520: test error: could not compile: /usr/local/go/src/internal/fuzz/sys_posix.go:19:18: PROT_READ not declared by package syscall
Do it all at once in preparation for Go 1.18 support.
To make this commit, I've simply modified the `fmt-check` Makefile
target to rewrite files instead of listing the differences. So this is a
fully mechanical change, it should not have introduced any errors.
readdir is disabled on linux for 386 and arm until syscall.seek is implemented there.
windows is hard, so leaving that for later.
File src/os/dir_other_go115.go can be deleted when we drop support for go 1.15.
Also adds TestReadNonDir, which was helpful while debugging.
This is File.Stat from https://github.com/tinygo-org/tinygo/pull/2371,
plus the windows bits,
plus a smoke test more or less from upstream,
all pulled together and rebased by dkegel-fastly.
File.Stat is left as a stub for now.
Tests are a bit stubbed down because os.ReadDir, os.Symlink, and t.TempDir are not yet (fully) implemented.
TODO: reimport tests from upstream as those materialize.
This is necessary for the following:
- to make sure os/exec can be imported
- to make sure internal/testenv can be imported
The internal/testenv package (which imports os/exec) is used by a lot of
tests. By adding support for it, more tests can be run.
This commit adds a bunch of new packages that now pass all tests.
