Becker A. (Nov 26 2023 at 07:03): Becker A. (Nov 26 2023 at 07:03):I'm trying to set myself up for development on the roc-lang/roc repo. I've done the following:
roc-lang/roc repo (main at 69b72866dbd7686ddd3b091516c683304328f292)nix develop, as described in the docscargo test, as described in the docs*edit - "the docs" -> https://github.com/roc-lang/roc/blob/69b72866dbd7686ddd3b091516c683304328f292/CONTRIBUTING.md#running-tests *
the cargo test command then generates test failures. more specifically:
$ cargo test -p roc_repl_expect --lib
running 26 tests
test test::big_recursive_tag_copied_back ... ok
test test::box_with_strings ... ok
test test::arg_parser ... ok
test test::equals_fail ... ok
test test::compare_long_strings ... ok
test test::extra_offset_in_tag_union ... ok
test test::adjacent_lists ... ok
test test::equals_pass ... ok
thread 'test::lookup_clone_result' panicked at 'misaligned pointer dereference: address must be a multiple of 0x8 but is 0x16f7add94', crates/repl_expect/src/app.rs:57:45
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
tests should work on main, right? am I doing something wrong?
Luke Boswell (Nov 26 2023 at 07:11):I'm not sure all tests should be working on main... maybe there is something special about that package? There are a lot of random packages, and may that is specific to WASM or dev backend or REPL or something special
Do tests work for you if you run cargo run --release?
Becker A. (Nov 26 2023 at 07:21):I tried cargo run --release and it looks like it's spitting out the same text I would get if I ran roc on it's own, i.e.:
$ cargo run --release
The current directory (/Users/___/Repos/roc) does not contain a main.roc file to use as a default.
You can run `roc help` for more information on how to provide a .roc file.
so it looks like the compilation is working! but this isn't the same as running tests, right? this just runs the main program compiled from source?
Becker A. (Nov 26 2023 at 07:28):I ask just because, from my interpretation of CONTRIBUTING.md, I should be running tests to confirm any changes I make to the source code. am I understanding that right?
Luke Boswell (Nov 26 2023 at 07:33):Yeah sorry I meant cargo test --release
Becker A. (Nov 26 2023 at 07:37):ahh gotcha, my bad I should've realized that's what you meant :sweat_smile: running now...
Becker A. (Nov 26 2023 at 07:43):all tests pass! thanks :+1:
-> should the docs be changed to note that tests should be run with --release?
Brian Carroll (Nov 26 2023 at 11:07):No, this should be a temporary situation so we shouldn't update the docs for it.
We should get the test working or ignore it.
Becker A. (Nov 26 2023 at 19:55):Gotcha. Should I put in a bug for it then?
Becker A. (Nov 26 2023 at 20:37):Went ahead a made a bug for this, feel free to close if that's not appropriate

Brian Carroll (Nov 26 2023 at 21:02):That's great, thanks!
