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
This commit implements various process related functions like
os.Getuid() and os.Getpid(). It also implements or improves this support
in the syscall package if it isn't available yet.
os.Getenv() was already stubbed out, but os.LookupEnv() wasn't. This
will allow me to compile my program unmodified without using separate
files and build tags.
