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)
TODO:
- enable test on arduino; currently fails with "interp: ptrtoint integer size..." (#2389)
- 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.
Add direct test for the problem to make the fix commit clearer.
Noticed while implementing MkdirTemp on mac; the upstream tests for MkdirTemp fail without this.
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.
FreeBSD support has been broken for a long time, probably since
https://github.com/tinygo-org/tinygo/pull/1860 (merged in May). Nobody
has complained yet, so I am going to assume nobody uses it.
This doesn't remove support for FreeBSD entirely: the code necessary to
build TinyGo on FreeBSD is still there. It just removes the code
necessary to build binaries targetting FreeBSD. But again, it could very
well be broken as we don't test it.
If anybody wants to re-enable support for FreeBSD, they would be welcome
to do that. But I think it would at the very least need a smoke test of
some sort.
WriteString just does the simple and and converts the passed string
to a byte-slice. This can be made zero-copy later with unsafe, if needed.
WriteAt returns ErrNotImplemented, to match Seek() and ReadAt().
Fixes#2157
