1rust: reproducibility issue fix with v1.80 2 3A few crates are using the updated version of the 'cc' crate and this is causing the generated object file names containing a unique hashmap id. 4By the following changes same hash values will be genarted even for diffrent build paths. 5 6Below are the links for detailed bug description & discusssion with upstream rust. 7https://github.com/rust-lang/cc-rs/pull/1277 8 9Upstream-Status: Submitted [https://github.com/rust-lang/cc-rs/pull/1277] 10Signed-off-by: Harish Sadineni <Harish.Sadineni@windriver.com> 11--- a/vendor/cc-1.0.97/src/command_helpers.rs 12+++ b/vendor/cc-1.0.97/src/command_helpers.rs 13@@ -257,6 +257,7 @@ 14 /// and store them in the output Object. 15 pub(crate) fn objects_from_files(files: &[Arc<Path>], dst: &Path) -> Result<Vec<Object>, Error> { 16 let mut objects = Vec::with_capacity(files.len()); 17+ let target_substring = ["rustc"]; 18 for file in files { 19 let basename = file 20 .file_name() 21@@ -277,10 +278,29 @@ 22 })? 23 .to_string_lossy(); 24 25+ // Function to find the position of the first occurrence of the target substring 26+ fn find_target_position(s: &str, targets: &[&str]) -> Option<usize> { 27+ let mut pos = None; 28+ for target in targets { 29+ if let Some(index) = s.rfind(target) { 30+ //If a target is found and pos is None, set it 31+ if pos.is_none() || index < pos.unwrap() { 32+ pos = Some(index); 33+ } 34+ } 35+ } 36+ pos 37+ } 38+ 39+ let filtered_dirname = if let Some(pos) = find_target_position(&dirname, &target_substring) { 40+ dirname[pos..].to_string() //Keep everything from the target substring onwards 41+ } else { 42+ dirname.to_string() //If target substring is not found, keep the original dirname 43+ }; 44 // Hash the dirname.
