200-206: Hardcoded 3600-second DST offset may be incorrect for some timezones.The calculation
c_timezone - 3600assumes DST offset is always 1 hour, but some regions use different DST offsets (e.g., Lord Howe Island uses 30 minutes). While the FIXME acknowledges this limitation, consider documenting which timezones may return incorrect values or adding a more prominent warning.The implementation follows the existing pattern in this module and is acceptable as a placeholder until proper C
altzonesupport is added.

Critical: Dangling reference and incomplete implementation.
Two significant issues:
-
Dangling reference (Line 1126):
&s.to_string_lossy()creates a temporaryCow<str>that is dropped at the end of the expression. The resulting&strreference would be invalid when used later. This should either fail to compile or cause undefined behavior. -
Unimplemented paths will panic (Lines 1123-1125): The
todo!()macros for "ignore", "replace", and "backslashreplace" will panic at runtime if these error handlers are used.
🔎 Proposed fix
To fix the lifetime issue, you need to own the string. One approach:
pub fn bytes_decode(
zelf: PyObjectRef,
args: DecodeArgs,
vm: &VirtualMachine,
) -> PyResult<PyStrRef> {
let DecodeArgs { encoding, errors } = args;
- let encoding = match encoding.as_ref() {
- Some(s) => match s.to_str() {
- Some(valid_str) => valid_str,
+ let encoding_owned: Option<String>;
+ let encoding: &str = match encoding.as_ref() {
+ Some(s) => match s.to_str() {
+ Some(valid_str) => valid_str,
None => {
let Some(errors) = &errors else {
return Err(vm.new_unicode_encode_error(format!(
"'{}' codec can't encode characters: surrogates not allowed",
s
)));
};
match errors.as_str() {
"strict" => {
return Err(
- vm.new_unicode_encode_error("Struct format must be a UTF-8 string")
+ vm.new_unicode_encode_error("encoding must be a valid UTF-8 string")
);
}
- "ignore" => todo!("TODO"),
- "replace" => todo!("TODO"),
- "backslashreplace" => todo!("TODO"),
- "surrogateescape" => &s.to_string_lossy(),
+ "ignore" | "replace" | "backslashreplace" => {
+ return Err(vm.new_not_implemented_error(
+ format!("error handler '{}' not yet implemented for encoding with surrogates", errors.as_str())
+ ));
+ }
+ "surrogateescape" => {
+ encoding_owned = Some(s.to_string_lossy().into_owned());
+ encoding_owned.as_ref().unwrap()
+ }
_ => {
return Err(vm.new_unicode_encode_error(format!(
"'{}' codec can't encode characters: surrogates not allowed",
s
)));
}
}
}
