From a5e8a0ea7c337225ba96248387b343f044205b7e Mon Sep 17 00:00:00 2001 From: Christopher Vittal Date: Mon, 9 Oct 2017 21:12:11 -0400 Subject: [PATCH 1/2] Modify MIR testing to require continuous lines Mir testing now requires that lines be continuous. To achive this, instead of collecting the expected mir as a string, it is now wrapped in an `ExpectedLine` enum, that is either `Elision` or `Text(T)` where `T: AsRef`. `Text` lines must be matched in order, unless separated by `Elision` lines. Matches occur greedily, that is, an Elision will skip as few lines as possible. To add a new elision marker. Put a comment containing only "..." and whitespace in any MIR testing block. Like so: ``` // fn write_42(_1: *mut i32) -> bool { // ... // bb0: { // Validate(Acquire, [_1: *mut i32]); // Validate(Release, [_1: *mut i32]); // ... // return; // } // } ``` Right now, all input before the line right after `// START` is elided, and all input after the line right before `// END` is also not tested. Many tests need to be updated. That will follow in the next commit. cc #45153 --- src/tools/compiletest/src/runtest.rs | 126 ++++++++++++++++++++------- 1 file changed, 94 insertions(+), 32 deletions(-) diff --git a/src/tools/compiletest/src/runtest.rs b/src/tools/compiletest/src/runtest.rs index 10ef326d9db8c..400599923ffea 100644 --- a/src/tools/compiletest/src/runtest.rs +++ b/src/tools/compiletest/src/runtest.rs @@ -25,6 +25,7 @@ use std::collections::HashSet; use std::env; use std::ffi::OsString; use std::fs::{self, File, create_dir_all}; +use std::fmt; use std::io::prelude::*; use std::io::{self, BufReader}; use std::path::{Path, PathBuf}; @@ -2237,7 +2238,7 @@ actual:\n\ let (_, tests_text) = test_file_contents.split_at(idx + "// END_RUST SOURCE".len()); let tests_text_str = String::from(tests_text); let mut curr_test : Option<&str> = None; - let mut curr_test_contents = Vec::new(); + let mut curr_test_contents = vec![ExpectedLine::Elision]; for l in tests_text_str.lines() { debug!("line: {:?}", l); if l.starts_with("// START ") { @@ -2251,11 +2252,14 @@ actual:\n\ self.compare_mir_test_output(curr_test.unwrap(), &curr_test_contents); curr_test = None; curr_test_contents.clear(); + curr_test_contents.push(ExpectedLine::Elision); } else if l.is_empty() { // ignore + } else if l.starts_with("//") && l.split_at("//".len()).1.trim() == "..." { + curr_test_contents.push(ExpectedLine::Elision) } else if l.starts_with("// ") { let (_, test_content) = l.split_at("// ".len()); - curr_test_contents.push(test_content); + curr_test_contents.push(ExpectedLine::Text(test_content)); } } } @@ -2273,7 +2277,7 @@ actual:\n\ } } - fn compare_mir_test_output(&self, test_name: &str, expected_content: &[&str]) { + fn compare_mir_test_output(&self, test_name: &str, expected_content: &[ExpectedLine<&str>]) { let mut output_file = PathBuf::new(); output_file.push(self.get_mir_dump_dir()); output_file.push(test_name); @@ -2285,38 +2289,77 @@ actual:\n\ let mut dumped_string = String::new(); dumped_file.read_to_string(&mut dumped_string).unwrap(); let mut dumped_lines = dumped_string.lines().filter(|l| !l.is_empty()); - let mut expected_lines = expected_content.iter().filter(|l| !l.is_empty()); + let mut expected_lines = expected_content.iter().filter(|&l| { + if let &ExpectedLine::Text(l) = l { + !l.is_empty() + } else { + true + } + }).peekable(); - // We expect each non-empty line from expected_content to appear - // in the dump in order, but there may be extra lines interleaved - while let Some(expected_line) = expected_lines.next() { + let compare = |expected_line, dumped_line| { let e_norm = normalize_mir_line(expected_line); - if e_norm.is_empty() { - continue; + let d_norm = normalize_mir_line(dumped_line); + debug!("found: {:?}", d_norm); + debug!("expected: {:?}", e_norm); + e_norm == d_norm + }; + + let error = |expected_line, extra_msg| { + let normalize_all = dumped_string.lines() + .map(nocomment_mir_line) + .filter(|l| !l.is_empty()) + .collect::>() + .join("\n"); + let f = |l: &ExpectedLine<_>| match l { + &ExpectedLine::Elision => "...
