I'm seeing this issue except I get: Unlike in alexcrichton/curl-rust#279 I only get it when trying to build for grcov with |

I'm getting the same error and I'm on nightly as well: |

I'm also seeing a similar issue in an Ubuntu-based Docker container: |
|
Interesting. Is there an example project that this fails for? It just works for me on a 2017 mbp with latest nightly (I'm using it on a small project though..). |
|
@gilescope unfortunately, I don't currently have a simplified project. I suspect it may be related to some of the way curl-rust is set up. But I can't say for certain. |
|
Ok so this could be a somewhat idiosyncratic error rather than being a general error affecting all osx users of grcov... Sent with GitHawk |
|
@gilescope definitely not unique to macOS since I saw something very similar in an Ubuntu Docker container. |

Documentation of [CFMutableAttributedString](https://developer.apple.com/documentation/corefoundation/cfmutableattributedstring-rqp) does not have function `CFMutableAttributedStringGetTypeID()` listed. 2. Documentation of [CFAttributedString](https://developer.apple.com/documentation/corefoundation/cfattributedstring-s1s) says that there is function `CFAttributedStringGetTypeID()` available (without word "Mutable"). 3. Documentation of [CFAttributedStringGetTypeID()](https://developer.apple.com/documentation/corefoundation/1541715-cfattributedstringgettypeid) says the following: > CFMutableAttributedString objects have the same type identifier as CFAttributedString objects. 4. As a double check - there is no `CFMutableAttributedStringGetTypeID()` function in C/C++ headers on MacOS, but `CFAttributedStringGetTypeID()` is available. C/C++ test program (similar to Rust above) does not compile as well. So, `CFAttributedStringGetTypeID()` must be used instead of `CFMutableAttributedStringGetTypeID()` ## Solution 1. In `core-foundation-sys`: Remove `extern CFMutableAttributedStringGetTypeID()` 2. In `core-foundation`: * Replace `CFMutableAttributedStringGetTypeID` with `CFAttributedStringGetTypeID` * Add test (compilation fails before the fix and is OK after the fix)

test: Fuzz testing RPC #2422 Fuzzer to test RPC connections, by sending: - [x] Invalid methods - [ ] Correct method with invalid formatted data - [x] Correct method with validly formatted random data How to run fuzzing ------------------- ```bach $ cd chain/jsonrpc $ cargo install cargo-fuzz # (if not installed) $ cargo fuzz run fuzz_target_1 ``` **Note** there is some bug in Rust, already fixed but still not included in nightly release, somehow related to MacOS Catalina, so fuzzing is possible only in Linux (definitely) and probably on Windows (haven't check). References: rust-lang/rust#63047 (comment) servo/core-foundation-rs#357 Test plan --------- 1. test query methods with valid random data and ensure RPC response status is 200 and response contains `error` key instead of `result`. 2. test for valid methods with invalid format of data. Should return 200 and `error` in response. 3. test for invalid methods

I'm getting this issue now as well active toolchainstable-x86_64-apple-darwin (default) |
EnvironmentmacOS Big Sur 11.1 |

There are still a lot of crates which depend on older version of core-foundation (e.g. 0.7). Test code (see above) with core-foundation = "0.9.1" and rustc 1.54.0-nightly works as expected without errors, coverage report is generated successfully. If you see errors, please check your crates dependencies, there should be an old core-foundation version somewhere in the tree. |
|
@vbadanov Does this mean that crates which depend on core-foundation should upgrade to the latest now? I imagine the situation will be similar to when Tokio went from 0.3 to 1.0, and it took a while for crates to upgrade. |
@seanpianka Yes. |
