From 9018d2c455df78d3f2900b4ced3ed63962e4f11e Mon Sep 17 00:00:00 2001 From: Nicholas Nethercote Date: Thu, 7 Dec 2023 09:53:08 +1100 Subject: Detect `NulInCStr` error earlier. By making it an `EscapeError` instead of a `LitError`. This makes it like the other errors produced when checking string literals contents, e.g. for invalid escape sequences or bare CR chars. NOTE: this means these errors are issued earlier, before expansion, which changes behaviour. It will be possible to move the check back to the later point if desired. If that happens, it's likely that all the string literal contents checks will be delayed together. One nice thing about this: the old approach had some code in `report_lit_error` to calculate the span of the nul char from a range. This code used a hardwired `+2` to account for the `c"` at the start of a C string literal, but this should have changed to a `+3` for raw C string literals to account for the `cr"`, which meant that the caret in `cr"` nul error messages was one short of where it should have been. The new approach doesn't need any of this and avoids the off-by-one error. --- src/tools/rust-analyzer/crates/parser/src/lexed_str.rs | 1 + src/tools/rust-analyzer/crates/syntax/src/validation.rs | 3 +++ 2 files changed, 4 insertions(+) (limited to 'src/tools/rust-analyzer') diff --git a/src/tools/rust-analyzer/crates/parser/src/lexed_str.rs b/src/tools/rust-analyzer/crates/parser/src/lexed_str.rs index b9e7566fdf9..3753a1beb7a 100644 --- a/src/tools/rust-analyzer/crates/parser/src/lexed_str.rs +++ b/src/tools/rust-analyzer/crates/parser/src/lexed_str.rs @@ -371,6 +371,7 @@ fn error_to_diagnostic_message(error: EscapeError, mode: Mode) -> &'static str { "non-ASCII character in byte string literal" } EscapeError::NonAsciiCharInByte => "non-ASCII character in raw byte string literal", + EscapeError::NulInCStr => "null character in C string literal", EscapeError::UnskippedWhitespaceWarning => "", EscapeError::MultipleSkippedLinesWarning => "", } diff --git a/src/tools/rust-analyzer/crates/syntax/src/validation.rs b/src/tools/rust-analyzer/crates/syntax/src/validation.rs index eabbda2c398..0504f67c9dc 100644 --- a/src/tools/rust-analyzer/crates/syntax/src/validation.rs +++ b/src/tools/rust-analyzer/crates/syntax/src/validation.rs @@ -106,6 +106,9 @@ fn rustc_unescape_error_to_string(err: unescape::EscapeError) -> (&'static str, EE::NonAsciiCharInByte => { "Byte literals must not contain non-ASCII characters" } + EE::NulInCStr => { + "C strings literals must not contain null characters" + } EE::UnskippedWhitespaceWarning => "Whitespace after this escape is not skipped", EE::MultipleSkippedLinesWarning => "Multiple lines are skipped by this escape", -- cgit 1.4.1-3-g733a5 From 9650c30fbb9e3741fbc4d01bc64496f7d725212e Mon Sep 17 00:00:00 2001 From: Weihang Lo Date: Thu, 18 Jan 2024 06:50:06 +0000 Subject: fix(rust-analyzer): use new pkgid spec to compare Starting from cargo#13311, Cargo's compiler artifact message uses Package ID specification as package's identifier format. --- .../crates/proc-macro-srv/proc-macro-test/build.rs | 16 ++++++++++++++-- 1 file changed, 14 insertions(+), 2 deletions(-) (limited to 'src/tools/rust-analyzer') diff --git a/src/tools/rust-analyzer/crates/proc-macro-srv/proc-macro-test/build.rs b/src/tools/rust-analyzer/crates/proc-macro-srv/proc-macro-test/build.rs index 6cf2b5643e5..e6903fb8d4a 100644 --- a/src/tools/rust-analyzer/crates/proc-macro-srv/proc-macro-test/build.rs +++ b/src/tools/rust-analyzer/crates/proc-macro-srv/proc-macro-test/build.rs @@ -92,12 +92,24 @@ fn main() { panic!("proc-macro-test-impl failed to build"); } + // Old Package ID Spec + let repr = format!("{name} {version}"); + // New Package Id Spec since rust-lang/cargo#13311 + let pkgid = String::from_utf8( + Command::new(toolchain::cargo()) + .current_dir(&staging_dir) + .args(["pkgid", name]) + .output() + .unwrap().stdout, + ) + .unwrap(); + let pkgid = pkgid.trim(); + let mut artifact_path = None; for message in Message::parse_stream(output.stdout.as_slice()) { if let Message::CompilerArtifact(artifact) = message.unwrap() { if artifact.target.kind.contains(&"proc-macro".to_string()) { - let repr = format!("{name} {version}"); - if artifact.package_id.repr.starts_with(&repr) { + if artifact.package_id.repr.starts_with(&repr) || artifact.package_id.repr == pkgid { artifact_path = Some(PathBuf::from(&artifact.filenames[0])); } } -- cgit 1.4.1-3-g733a5
