OSX support tracking issue #152
Comments
|
So tarpaulin currently only supports linux, if anything else works it's more luck that intent. OSX compared to linux doesn't have a complete ptrace implementation so the nix crate doesn't expose the ptrace bindings. If anyone was interested in adding OSX support they'd need to either replace ptrace with appropriate mac system calls or contribute to nix to add the parts of ptrace mac exports and for the rest of it add the appropriate system calls. I don't have any Macs so while I'm open to more OS support this is something I'd appreciate help on. |
|
Do you know of any tools that can be used on OSX for coverage reports?, would a donation to the project help? |
|
You might be able to get it working with docker on mac - though I'm not really that familiar with docker so maybe not... A good start if you wanted to help for the ptrace calls on mac. It should just be a case of looking at the ptrace docs for OSX finding what's supported and changing the cfgs in https://github.com/nix-rust/nix/ to match. Once that's done and merged in it we can see what fails to compile and go from there. As for donations I hadn't considered project donations before, though I'm probably going to be rather busy with my day job till the end of the year so that probably won't change anything in reality. |
|
Oh realised I missed your first question on tools that can be used for coverage, there is https://github.com/SimonKagstrom/kcov which works on linux, freebsd and OSX. I've just opened a PR on rust-nix/nix nix-rust/nix#949 for ptrace support in OSX and BSD. So once that's done, released and I update tarpaulin for the new nix version tarpaulin might work on OSX or there might be other things that need adapting. I'll ping you when there' something to test though! Edit: Notes for me -

I guess I could setup a cron job to clone the repo and run the tests on this machine, like daily, if that is something you guys would find useful. |
|
No that's alright I got it more working some point last night and affirmed that travis is fine for testing. Thanks for offering though! Once this is in and released I'll be able to apply some changes to tarpaulin and may ask you to test them |
|
Just put them here I guess

There's now a tracking branch for this. https://github.com/xd009642/tarpaulin/tree/osx-support I don't yet expect it to work but the ptrace compiler errors should be gone (in theory) |
|
So tarpaulin now builds but doesn't work on OSX. I'm going to edit your first comment to add a checklist of things that need doing so it actually shows up towards the issue progress and to generally keep things tidy. Gonna try and keep the original text in a collapsable markdown block for posterity though |
|
I like it because it makes my comment look more professional. |
|
So as an update since I've been working on this issue this week. I appear to have ported over most of the ptrace stuff launch a test add the breakpoints to instrument it but after initialising the test it times out. This makes me think the trace isn't being passed down to the child threads and rustc_test does spawn a thread for each test so it can kill it if it runs too long. Hopefully, once I solve this issue I might see some coverage results come out (if I'm really lucky and everything else works to some degree). |
|
@dataf3l it would be helpful if you could take the latest build off the osx-support branch and create the default lib project Also, if the outputs big upload it in a text file or link to a gist |
|
@xd009642 I've just wandered in from "This Week in Rust" and have zero context for this issue, but I gave it a go:
|
|
Oh that's actually super useful! Could you run ddbug on the dsym file? |
|
Awesome that's what I expected to see! I've been trying to debug and develop this via travis and apples online docs which has been a bit of a mare. I've pushed a change to the If more work is needed (I have a feeling there is more) and you're interested in working on the tarpaulin code I've got a developer wiki that explains some of how the project works https://github.com/xd009642/tarpaulin/wiki/Developers if there are any missing parts or issues I do also have a tracking issue for the wiki since it's relatively new 👍 |
|
That overview's given me the gist of how this is supposed to work 👍. At the minute #[cfg(target_os = "macos")]
fn open_symbols_file(test: &Path) -> io::Result<File> {
- let d_sym = test.with_extension("dSYM");
+ let mut d_sym = test.with_extension("dSYM");
+ d_sym.push("Contents/Resources/DWARF");
+ d_sym.push(test.file_stem().unwrap());
println!("Test file {}", d_sym.display());
File::open(&d_sym)
}Which leads to: I guess this could be a privilege issue (codesigning/entitlements) or some macOS API deviation. I've got to shelf this for the moment but I'll try and circle back to this in the next few days. |
|
So the mach-o loading side of thing looks like it's working with that change as it's found the traces from the DWARF tables. This is in the update loop actually attempting to trace. I think this is a case of Apple doesn't expose the constants but provides more ptrace functionality than they advertise so I hard coded it myself to see if it would work. So looks like back to the apple ptrace drawing board for that |
|
@nathanwhit sorry for the random tag but I saw you tried some stuff with OSX support in a fork, did you make any progress or have any insights? I'm going to be borrowing a mac from a friend this week so might be able to make some real progress once I can run the code locally |
|
@xd009642 No worries! I did make some progress. The main issue is that (as you noticed) ptrace on macOS doesn't have the right capabilities so you have to work through other means. More specifically you have to go through the kernel's mach interface. I have two branches with my progress, I'll go through the progress and problems with each. My first attempt was the My second attempt was the I've pushed my latest changes to both branches, you're welcome to continue where I left off. |
|
One important note is that for any of it to work you have to run with Also, if you want to work/mess around with just the mach side of things I have a repo with some basic tests I used for debugging/developing the mach interface. Just build a binary with the name Feel free to ping me if you have any questions/thoughts. I'm still open to working on this, just right now I don't have enough bandwidth to continue. |
|
I am happy to see some progress on this. I would love to help, but I am swamped with a lot of other projects. |
|
@nathanwhit could you explain a bit what the build.rs is doing in the macos-v2 branch? |
|
@xd009642 Ah yeah sure, forgot about that. The following is what I've gathered from a few sources: the The mach messaging/RPC interface (headers, etc.) is actually generated by a program on the system (called |
|
Awesome, and I've never looked at the lldb code only gdb but that seemed extra opaque with mac stuff. I'll start looking to lldb for reference when gdb is too much 😅 |
|
So few issues so far, I'm working with Darwin and the Mac system headers moved but I've updated the build script. Now my current roadblock is |
|
just found this https://github.com/kattrali/rust-mac-app-examples/tree/master/3-packaging-a-mac-app which I think shows me how to handle the permissions for an app 🎉 I'll have another play with this at the weekend |

Hi! Do you have any updates of plan for this? I've been using Docker to run Tarpaulin, but it takes much longer and forces me to have Docker up and running. Having Tarpaulin working natively on Mac would be awesome. |
|
@tsauvajon so this is the current approach I'm approaching for easier cross platform support #549 the only update since I last posted on that issue is I can parse and merge the profdata formats in pure rust. I just need to extract the coverage counters from the test binaries and then set about integrating it into tarpaulin. It's just a bit of a slog since for a lot of this the LLVM source code is the documentation |
|
So anyone still interested go over to llvm coverage tracking issue and try it out #549 you can install from feature branch |
|
So mac has deviated from windows and I get a "permission denied" error on doc test coverage using the llvm coverage on CI. If anyone has a mac I'd appreciate some help 🙏 |
|
I think it's working fine for me! Here's the output from I'm on an M1 MacBook Pro. Let me know if you want me to try something specific out. I'm not super familiar with Tarpaulin yet |
|
Great to hear it works on heapless 🎉. It should work on majority of crates given number of CI tests passing, there are some failures still on Mac CI which lives in #549 . Notable ones are doc-test coverage and following spawned programs (though that's not working on linux so I can fix that). |
|
In MacOS 12.5 in a MacBook with M1, running it in a private project with --engine llvm I got this panic (last commit in the branch: |
|
So this is now merged and some point this week there shall be a new release on crates.io (probably tomorrow). closing this issue in favour of #549 I did spend all the time from around July till now fixing edge cases and panics I found on different projects so hopefully your issue is now fixed @Razican . If not head over to #549 🙏 |
