Noticing that "unitless" is capitalized as if it was two words in the isUnitLessValueParsingEnabledForMode function. > Source/WebCore/css/parser/CSSPropertyParserHelpers.cpp:319 > + CalcParser calcParser(range, CalculationCategory::Number, valueRange, symbolTable, cssValuePool); > + return calcParser.consumeValueIfCategory(CalculationCategory::Number); Just call the local variable "parser?" When the scope is this tight, for me the single word just makes the code more readable even if it’s not entirely unambiguous. > Source/WebCore/css/parser/CSSPropertyParserHelpers.cpp:504 > +static RefPtr<CSSPrimitiveValue> consumeLengthCSSPrimitiveValueWithCalcWithKnownTokenTypeNumber(CSSParserTokenRange& range, const CSSCalcSymbolTable& symbolTable, ValueRange valueRange, CSSParserMode cssParserMode, UnitlessQuirk unitless, CSSValuePool& cssValuePool) Consider taking of the extra words off some of these argument names? I would just call the CSSValuePool pool. > Source/WebCore/css/parser/CSSPropertyParserHelpers.cpp:1223 > +static inline bool divisibleBy100(double value) > +{ > + return static_cast<int>(value / 100) * 100 == value; > +} This works only because the caller already checks that the value is in range between 0 and 100. I think it’s also non-obvious that this checks if the number is an integer as a side effect. > Source/WebCore/css/parser/CSSPropertyParserHelpers.cpp:1239 > +#if !ENABLE(VARIATION_FONTS) > + if (*result <= 0 || *result >= 1000 || !divisibleBy100(*result)) > + break; > +#endif I noticed that the code below does [1,1000] but this does [0,1000]. > Source/WebCore/css/parser/CSSPropertyParserHelpers.cpp:1245 > + if (result < 1 || result > 1000) For better NaN handling I think we want to reverse the logic: if (!(result >= 1 && result <= 1000)) 1765620 4 430264 sam 2021-06-01 08:24:38 -0700 Created attachment 430264 Patch 1765647 5 ews-feeder 2021-06-01 09:49:15 -0700 Committed r278311 (238348@main): <https://commits.webkit.org/238348@main> All reviewed patches have been landed.
