When using the latest wasi-libc I experienced a
panic on an attempt to call realloc. My first attempt to
add it to arch_tinygowasm.go was obviously not good (PR #2194). So here
is another suggestion.
Operations on nil maps are accepted and shouldn't
panic. The base hashmapGet/hashmapDelete handled
nil-maps correctly, but the hashmapBinary versions
could segfault accessing the nil map while trying
to hash the key.
Fixes#2341
This allows positive and negative zero to hash to the same value,
as required by Go.
This is not perfect, but the best I could do without
revamping all the hash funtions to take a seed.
Fixes#2356
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.
Previously, -scheduler=none wasn't possible for WASM targets:
$ tinygo run -target=wasm -scheduler=none ./testdata/stdlib.go
src/runtime/runtime_wasm_js.go:34:2: attempted to start a goroutine without a scheduler
With this commit, it works just fine:
$ tinygo run -target=wasm -scheduler=none ./testdata/stdlib.go
stdin: /dev/stdin
stdout: /dev/stdout
stderr: /dev/stderr
pseudorandom number: 1298498081
strings.IndexByte: 2
strings.Replace: An-example-string
Supporting `-scheduler=none` has some benefits:
* it reduces file size a lot compared to having a scheduler
* it allows JavaScript to call exported functions
