Optimize path mapping lookups #59048

DanielRosenwasser · 2024-06-27T00:53:27Z

When checking if a specifier satisfies a pattern (e.g. for a path mapping entry in paths), it seems like TypeScript needs to check every single available pattern to see if the specifier is matched.

Here, I've slightly modified the code to create a Set of exact specifiers, and a sorted array of all Patterns. The Set becomes a fast look-up, and the sorted array allows us to do a binary search to find the group of patterns with the longest applicable prefix less than or equal to the candidate itself.

The algorithm then finds the first pattern in the group of identical prefixes, and checks for a match walking upward until the end of the group. That itself might not succeed if none of the suffixes match, so the code then falls back to the same linear search as before (albeit, bounded to avoid checking the same patterns as before).

This also adds two caches: one to avoid creating separate string and pattern input arrays for each call, and one to avoid recalculating the set and sorted array each time. Technically, if the array is never referenced, we could cache the latter directly.

Note that this work is not resilient to being passed the same array of patterns twice with different contents.

TODOs:

Flip condition for walking through the array
Break up function into smaller pieces
Add failing test, harden logic for export map ordering by suffix
Move caching logic to tryParsePatterns.
Make tryParsePatterns just return a { stringSet, patternArray } pair instead of a list.

…uickly. This also adds a naive cache for each call, though it is not resilient to being passed the same array of patterns twice with different contents, and could be defeated if the patterns frequently differ.

I don't know if our perf suites have repos with lots of path mappings, but...

Hey @DanielRosenwasser, I've packed this into an installable tgz. You can install it for testing by referencing it in your package.json like so:

{
    "devDependencies": {
        "typescript": "https://typescript.visualstudio.com/cf7ac146-d525-443c-b23c-0d58337efebc/_apis/build/builds/162456/artifacts?artifactName=tgz&fileId=E2F93981315A9DC4E4D25A7C90DF0240EEFB23C524E61C1D39685D480869765C02&fileName=/typescript-5.6.0-insiders.20240627.tgz"
    }
}

and then running npm install.

There is also a playground for this build and an npm module you can use via "typescript": "npm:@typescript-deploys/[email protected]".;

…ping/pong situation.

DanielRosenwasser · 2024-06-27T18:25:58Z

In some experiments on internal codebases, this seems to shave off maybe 200-300ms depending on the project (they are using pretty big lists of path mappings), but it looks like it ends up in a situation where the function gets called with two different arrays in an interleaving way. So instead of a single-slot cache, I added a WeakMap.

Hey @DanielRosenwasser, I've packed this into an installable tgz. You can install it for testing by referencing it in your package.json like so:

{
    "devDependencies": {
        "typescript": "https://typescript.visualstudio.com/cf7ac146-d525-443c-b23c-0d58337efebc/_apis/build/builds/162471/artifacts?artifactName=tgz&fileId=E81886FA4EB3F7B8BEB31252C9121DC5B98039962996BF8EF2C70B005CCCAED902&fileName=/typescript-5.6.0-insiders.20240627.tgz"
    }
}

and then running npm install.

There is also a playground for this build and an npm module you can use via "typescript": "npm:@typescript-deploys/[email protected]".;

src/compiler/core.ts

    let matchedValue: T | undefined;
    // use length of prefix as betterness criteria
    let longestMatchPrefixLength = -1;

-    for (let i = 0; i < values.length; i++) {
+    for (let i = 0; i < endIndex; i++) {
        const v = values[i];
        const pattern = getPattern(v);
        if (isPatternMatch(pattern, candidate) && pattern.prefix.length > longestMatchPrefixLength) {


Wouldn't it be better to run these conditions in the reverse order? No point in running the cost of pattern matching if the pattern to be matched is a worse fit than the current best.

In practice, what will probably happen is we'll have an empty prefix, that'll match, and then everything after will still need to be checked. It probably makes sense to walk the list backwards looking for a match in case a long match is found, and then bail out as soon as an entry with a shorter prefix length is encountered.

+        return undefined;
+    }
+
+    let index = binarySearchKey(sortedPatterns, candidate, getPatternPrefix, compareStringsCaseSensitive);


In Rush we have to efficiently match a large array of Git file paths to project prefixes as part of hashing our input states; for that we use this class which you might find useful for this application: https://github.com/microsoft/rushstack/blob/main/libraries/rush-lib/src/logic/LookupByPath.ts

For some numbers, that tool matches 142936 unique file paths to 1279 unique path prefixes in 62 milliseconds on my codespace machine (single threaded). This is without taking any advantage of that the list of paths returned by Git are technically sorted.

I think the latest change helped a bit; however, it seems like frequently this function ends up with an (effectively) identical list every single time with different reference equality. So I've tried adding an earlier cache. I'll see if that helps.

Hey @DanielRosenwasser, I've packed this into an installable tgz. You can install it for testing by referencing it in your package.json like so:

{
    "devDependencies": {
        "typescript": "https://typescript.visualstudio.com/cf7ac146-d525-443c-b23c-0d58337efebc/_apis/build/builds/162476/artifacts?artifactName=tgz&fileId=9683B5E6F6215D023679DE14CBF28D3038EEB938A0C5B3E05A39FA272049907B02&fileName=/typescript-5.6.0-insiders.20240627.tgz"
    }
}

and then running npm install.

There is also a playground for this build and an npm module you can use via "typescript": "npm:@typescript-deploys/[email protected]".;

DanielRosenwasser · 2024-06-27T19:43:44Z

For whatever reason, I'm still seeing at least one occurrence of an identical path array being passed in; but I think this is pretty ready for review.

@DanielRosenwasser Here are the results of running the top 400 repos with tsc comparing main and refs/pull/59048/merge:

Everything looks good!

DanielRosenwasser · 2024-06-27T21:25:26Z

Something for me to look into here is that I sort by longest prefix; but I believe for export maps the longest prefix has to account for the total length of the pattern as a tie-breaker (https://github.com/nodejs/node/blob/8f39f51cbbd3b2de14b9ee896e26421cc5b20121/lib/internal/modules/esm/resolve.js#L722). I think that is subtly different from TypeScript's paths.

Hey @DanielRosenwasser, I've packed this into an installable tgz. You can install it for testing by referencing it in your package.json like so:

{
    "devDependencies": {
        "typescript": "https://typescript.visualstudio.com/cf7ac146-d525-443c-b23c-0d58337efebc/_apis/build/builds/162490/artifacts?artifactName=tgz&fileId=27DEFAE31BA46043602E8EC7B370C23C6112093A37CB36C9F004946F31C8DFD002&fileName=/typescript-5.6.0-insiders.20240628.tgz"
    }
}

and then running npm install.

There is also a playground for this build and an npm module you can use via "typescript": "npm:@typescript-deploys/[email protected]".;

Hey @DanielRosenwasser, I've packed this into an installable tgz. You can install it for testing by referencing it in your package.json like so:

{
    "devDependencies": {
        "typescript": "https://typescript.visualstudio.com/cf7ac146-d525-443c-b23c-0d58337efebc/_apis/build/builds/162492/artifacts?artifactName=tgz&fileId=9A43BB1F5015C8E1240596441929304490B5CF692A75D0C591BEAA8E193450A502&fileName=/typescript-5.6.0-insiders.20240628.tgz"
    }
}

and then running npm install.

There is also a playground for this build and an npm module you can use via "typescript": "npm:@typescript-deploys/[email protected]".;

The current state of this just always caches the objects and divides the entries into exact specifiers (as a Set) and an array of patterns as written. This still helps the internal codebase in question since about half of the entries in the huge list are non-pattern specifiers.

I'm open to re-introducing the binary search. It probably still makes sense to sort the array and iterate backwards to find a match and bail earlier when possible. But apparently we don't seem to have a test where suffix length matters in the case of exports, and I'd need someone to make sure I get the details there right.

…uickly. This also adds a naive cache for each call, though it is not resilient to being passed the same array of patterns twice with different contents, and could be defeated if the patterns frequently differ.
