"exclude" will NOT work SOMETIMES when there are tons of files in project

[ygweric]

background

my h5 page is in the same project when my web page, I only use pxtorem in my h5 page, exclude all my web page.

the bug

it works well in my localhost, but in the online environment which is build with jenkins, web page is using rem sometimes, not always.

After I rebuild on jenkins, it works well again.

It is hard to create a large project to reproduct this bug.

Here is my way to find bug and how to fix it.

I download the source and copy them to my project, then add some log to debug it .

what I found is, the file path in Declaration(decl) and Once(css) is NOT same sometimes.
there is my code

module.exports = (options = {}) => {
  convertLegacyOptions(options);
  const opts = Object.assign({}, defaults, options);
  const satisfyPropList = createPropListMatcher(opts.propList);
  const exclude = opts.exclude;
  let isExcludeFile = false;
  let pathOnec;
  let pxReplace;
  return {
    postcssPlugin: "postcss-pxtorem",
    Once(css) {
      const filePath = css.source.input.file;
      pathOnec = filePath;
      if (
        exclude &&
        ((type.isFunction(exclude) && exclude(filePath)) ||
          (type.isString(exclude) && filePath.indexOf(exclude) !== -1) ||
          filePath.match(exclude) !== null)
      ) {
        isExcludeFile = true;
      } else {
        isExcludeFile = false;
      }

      const rootValue =
        typeof opts.rootValue === "function"
          ? opts.rootValue(css.source.input)
          : opts.rootValue;
      pxReplace = createPxReplace(
        rootValue,
        opts.unitPrecision,
        opts.minPixelValue
      );
    },
    Declaration(decl) {
      if (isExcludeFile) return;
      console.log(` $$$$$$$ step2: Declaration(decl) ${decl.source.input.file}`);
      console.log(` $$$$$$$ step2.1: pathOnec is ${pathOnec === decl.source.input.file ? 'same': `different: ${pathOnec}`}`);


      if (
        decl.value.indexOf("px") === -1 ||
        !satisfyPropList(decl.prop) ||
        blacklistedSelector(opts.selectorBlackList, decl.parent.selector)
      )
        return;

      const value = decl.value.replace(pxRegex, pxReplace);

      // if rem unit already exists, do not add or replace
      if (declarationExists(decl.parent, decl.prop, value)) return;

      if (opts.replace) {
        decl.value = value;
      } else {
        decl.cloneAfter({ value: value });
      }
    },
    AtRule(atRule) {
      if (isExcludeFile) return;

      if (opts.mediaQuery && atRule.name === "media") {
        if (atRule.params.indexOf("px") === -1) return;
        atRule.params = atRule.params.replace(pxRegex, pxReplace);
      }
    }
  };
};

there is part of my full log

After reading the documentation of postcss, I know postcss NEVER ensure that Declaration(decl) and Once(css) always in sync

hi, so is there any way to solve this problem ?

[hq229075284]

Take version fallback to 5.1.1 😑

hi, so is there any way to solve this problem ?
I fix it in my PR #102, which has NOT been merged
you can use my forked npm with npm i postcss-pxtorem-eric

Here is still a problem in your solution

The problem in 6.0.0 is applying incorrect rootValue to target file

In your solution, some files not in exclude can be skipped too
