I think the bug can be fixed by removing the initial value of shouldSetCache

- let shouldSetCache = !isDifferent;
+ let shouldSetCache = false;

Will it work?

Also, we need tests for this case.

Will it work?

It seems don't work. If the file is ignored, it gets an early return.

  const isFileIgnored = isIgnored(filename);
  if (
    isFileIgnored &&
    (context.argv.debugCheck ||
      context.argv.write ||
      context.argv.check ||
      context.argv.listDifferent)
  ) {
    continue;
 }

Hello @kovsu , sorry for the long delay.

Do you know why we need removeFormatResultsCache? Shouldn't the file hash mismatch on the second run?

For example:

If I run prettier foo.js bar.js --no-single-quote --write, we will cache result for both foo.js and bar.js. Then I run prettier foo.js --single-quote --write, will we remove the cache for bar.js?

This really doesn't make sense to me, since each command can even have a different cache location.

It looks like there's been no action on this PR since November - is it dead? Is there a different fix for #18016 somewhere?

Maybe caused by jaredwray/cacheable#1648?

Maybe caused by jaredwray/cacheable#1648?

Yes, I will confirm this when it publish the new version.

jaredwray/cacheable#1648 won't get released in time, I'll merge this and release v3.9 and revisit later.
