Rework our version matching algorithm #217

paulo-ferraz-oliveira · 2023-06-23T12:57:02Z

This:

bumps dependencies' versions to their latest, where appropriate
trims GitHub Actions' workflows, where appropriate
trims package.json, where appropriate
tweaks getVersionFromSpec/2 to improve on version matching
adapts test and CI

.github/workflows/action.yml

-      - run: npm install
-      - run: npm run build
-      - run: npm run format
-      - run: npm install -g markdownlint-cli


This was moved to package.json which means this whole npm ... pipeline can simply be as it is proposed here.

-            otp-version: '22.3.4.1'
-            os: 'ubuntu-20.04'


We find this above, already, with version-type: strict.

Not really used, I guess. npm run build-dist does it all.

-    "eslint-plugin-react": "7.31.10",
-    "husky": "8.0.1",


Not really used, so we can trim down a few deps.

starbelly · 2023-06-24T16:19:58Z

It is my experience that it's rare the development community at large targets versions like 25.3.2.1, preferring to stay at the 25.3.x level.

Yeah, I agree with that, but the fact remains still that even 25.3.1 is not semver in the case of OTP. However, I think it's fair to say it can be treated like that. I would agree this is a breaking change. So, we're thinking this would result in a new major version then, is that correct?

paulo-ferraz-oliveira · 2023-06-24T21:20:06Z

It'd probably result in a breaking change, yes, depending on:

whether we consider it to be a bug (which it is since we've not been handling it properly), or
we consider it to be a new feature we want the action to present.

I "think" I can try to fit the x.y.z.a versions in the mix (maybe?), but I tried the other day and the solution got so convoluted I rolled back some decisions: I also don't like that I'm forced to write 25.3.2.2, strict, because my consumer's expectation is 25.3.2 is whatever is before 25.4.0, but... Now I got (merge) conflicts, I got solve those and we can continue discussing this to see what our common expectation is.

Edit: Ok, so I'm trying a new approach where I compare version suffixes to a fixed version.

paulo-ferraz-oliveira · 2023-06-25T00:01:44Z

I rebased to resolve merge conflict and increased complexity for getVersionFromSpec/2 (hopefully not by much) so we can keep previous behaviour but make the code easier to maintain, also...

Edit: also, since the last commit, I moved back most changes in the .test.js module, so we make sure whatever was there works as-was, but we have new behaviour working properly too.

src/setup-beam.js

-  if (isVersion(otpSpec0)) {
-    otpSpec = `OTP-${otpSpec0}` // ... it's a version!
-  }


The result of this block was never used. I don't know why static analysis wouldn't find this...

Needs hank.

+  return new RegExp(
+    `${pref}v?(\\d+)${dd}${dd}${dd}${dd}${dd}(?:-rc\\.?\\d+)?(?:-otp-\\d+)?${suf}`,

This function, and its callers, will probably be the "most difficult bits" to maintain, but the regexps here are pretty relaxed, too...

@paulo-ferraz-oliveira This LGTM. I'd be in favor of merging and a delay on the release, sound good?

paulo-ferraz-oliveira · 2023-07-21T19:48:14Z

Sure. We can merge and delay release. That'll give me a chance to update the other pull request I have opened.

We want the most important things to fail first and prevent the other ones from executing e.g. if your dist/ is not updated, there's no point seeing the tests fail

We'll deal with all this in a centralized place to make it easier to reason on the code

1. stop accepting maybePrependWithV0, since this is only used in specialized cases 2. sort versions internally (don't expect it to come sorted) 3. compare rc/strict and .includes in a single go (don't separate these) 4. don't expect already coerced version arrays, coerce them when required (the maybeCoerced version had changed already, which means we're smarter at putting stuff inside the version array) 5. raise an exception if a semver-invalid version is not flagged as strict

This reverts commit 500b0fe.

This reverts commit fbe1317.

We cheat on the semver matching: 1. we keep an ordered list of versions that respect e.g. 22.3.4 2. if we match 22.3.4 when fetching a version, we get the last value from the list of versions that respect it, e.g. 22.3.4.2.1.0 (since this is ordered, it should work as previously expected) This increases code complexity for getVersionFromSpec, but hopefully not by much... We also remove throw-based test cases (non-versions will fail later, with null), and add some tests to prove our need code.

But still keep them useful

paulo-ferraz-oliveira · 2023-07-21T19:52:04Z

Force-pushing to resolve merge conflicts. If no actions show issues I'm squash-merging.

josevalim · 2024-01-17T14:18:19Z

Thank you @paulo-ferraz-oliveira! It seems this PR removed support for maint/master from OTP git, which Elixir relies on. Was it intentional?

josevalim · 2024-01-17T14:21:50Z

Nevermind, PR sent here: #241 :)
