1.15 specific files deleted.
1.16 specific files folded carefully into generic files, with goal of reducing diff with upstream.
Follows upstream 1.16 in making PathError etc. be aliases for the same errors in io/fs.
This fixes#2817 and lets us add io/ioutil to "make test-tinygo" on linux and mac.
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.
This test creates a new temp file and writes some bytes into it.
It then opens a new file for the file descriptor of the temp file and
tries to read some bytes out of it.
These are used in Go 1.18's `testing/internal/testdeps`. Though the
comment says they should exist _everywhere_, there is still a build
constraint, but that seems to be fine.
This commit adds stubs for the `ExitError` struct of the `exec` package
and `ProcessState.ExitCode()` of the `os` package.
Since the `os/exec` is listed as unsupported, stubbing these methods
and structs should be enough to get programs that use these to compile.
This appears to have been how it is upstream for about 10 years. Using
an interface breaks if a file descriptor number is passed directly to
`NewFile`, e.g., `NewFile(3, "fuzz_in")` as used in Go 1.18 fuzzing
code.
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.
It's wafer-thin :-)
Includes smoke test from upstream.
TODO: once t.TempDir is implemented, add io/fs to the list of standard library tests to run; that's a better test.
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 replaces an earlier kludge which was at the wrong level
and caused "GOARCH=386 tinygo test os" to fail to compile on linux.
Stubbing just the one missing function, syscall.seek, lets
os tests compile on linux 386, and skipping tests of seek and Fstat
(which has a cryptic dependency on syscall.Seek via time)
lets os tests pass on linux 386.
The stub can be removed once tinygo implements go assembly and picks up the real definition.
Test currently enabled on pybadge (chosen at random)

- enable test on nintendoswitch; currently fails with many missing definitions (#2530)
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.
On wasi, O_RDWR is a bitwise or of read and write mode.
As a result, the bit test result was incorrect, and rewrote it to read-write mode.
However, the bit tests are not necessary (and upstream Go does not use them).
This passes the flags through directly.
Also fix a couple os tests that wrote to current directory to write to os.TempDir() instead.
After this, os tests pass in wasi, so add them to the list run by "make tinygo-test-wasi".
This matches what upstream Go does. This also means len(b) == 0 successfully
reads 0 bytes without any extra logic. The tests in archive/zip test for this
behaviour.
