Avoid parsing other parts of a format specification if replacements are present #6858

zanieb · 2023-08-24T19:31:35Z

Closes #6767
Replaces #6773 (this cherry-picks some parts from there)
Alternative to the approach introduced in #6616 which added support for placeholders in format specifications while retaining parsing of other format specification parts.

The idea is that if there are placeholders in a format specification we will not attempt to glean semantic meaning from the other parts of the format specification we'll just extract all of the placeholders ignoring other characters. The dynamic content of placeholders can drastically change the meaning of the format specification in ways unknowable by static analysis. This change prevents false analysis and will ensure safety if we build other rules on top of this at the cost of missing detection of some bad specifications.

Minor note: I've use "replacements" and "placeholders" interchangeably but am trying to go with "placeholder" as I think it's a better term for the static analysis concept here

- Err(FormatSpecError::InvalidFormatType)
+ // Note this should be an `InvalidFormatType` but we give up
+ // on all other parsing validation when we see a placeholder
+ Ok(FormatSpec::Dynamic(DynamicFormatSpec {
+ placeholders: vec![FormatPart::Field {
+ field_name: String::new(),
+ conversion_spec: None,
+ format_spec: String::new()
+ }]
+ }))


Here's an example case where we no longer detect invalid format type specifications because there was a replacement earlier — this is a trade-off for generally safer analysis.

 #[test]
- fn test_format_part_with_others() {
- let expected = Ok(FormatSpec {
- conversion: None,
- fill: None,
- align: Some(FormatAlign::Left),
- sign: None,
- alternate_form: false,
- width: Some(20),
- grouping_option: None,
- precision: None,
- format_type: Some(FormatType::Binary),
- replacements: vec![FormatPart::Field {
+ fn test_dynamic_format_spec_with_others() {
+ let expected = Ok(FormatSpec::Dynamic(DynamicFormatSpec {
+ placeholders: vec![FormatPart::Field {
 field_name: "x".to_string(),
 conversion_spec: None,
 format_spec: String::new(),
 }],
- });
+ }));
 assert_eq!(FormatSpec::parse("<{x}20b"), expected);
 }


Here we lose all these additional fields which were correct in this test but could be wrong depending on the dynamic content of the placeholder.
