V4 tracker #479

s1na · 2019-03-22T07:36:36Z

This PR tracks the changes planned for v4 (see #455). It also acts as a base branch for the pull requests, to prevent mixing experimental development in master. This'd allow us to maintain v3, fix bugs and do releases independently of the changes made here, and also have parallel release candidates for v4.

coveralls · 2019-03-22T07:59:06Z

Coverage decreased (-0.3%) to 94.95% when pulling 00f99c2 on v4 into 068db32 on master.

lib/evm/interpreter.js

+const PStateManager = require('../state/promisified')
+
+module.exports = class Interpreter {
+  constructor (vm, txContext, block, storageReader) {


General note: I think every access through _vm here is an indicator that we have some misplacement of code or suboptimal structure.

* Detach list of precompiles from VM * evm: add getPrecompile method to interpreter

* Promisify runTx internals * Fix linting error

* Drop babel deps, add initial typescript config * Add prettier as dep, add format scripts * Mv bloom/index.js to bloom/index.ts * Migrate bloom to ts, limit its api to buffers * Mv lib/evm/stack.js to lib/evm/stack.ts * Migrate stack to ts, limit it to BN * Mv lib/evm/memory.js to lib/evm/memory.ts * Migrate evm memory to ts * Build:dist before coverage and api browser tests * Use tester dist flag for coverage tests

* Mv lib/state/promisified.js to lib/state/promisified.ts * Change state file types to ts * Migrate state module to ts

Looks like v4 release is on the horizon. Looking forward to it.

Visiting the repo after long time & you have made awesome strides with ethereum VM in JS, making ethereum development very smooth and hopefully helping blockchain reach its true potential

@s1na if you feel comfortable with that I would suggest we try to do the master merge here on Monday and do subsequent cleanup work towards the master branch. Then we have two days where the dust can settle on the master branch and we see through a bit again on Wednesday. 😄 😋

Can you do some master rebase here (this would be the procedure, right?)?

Let me know if you have any reservations, in doubt we are not completely bound to this date in any way and should rather make sure that the process is robust and we are confident with the integration work.

s1na · 2019-05-27T10:10:23Z

That sounds good to me. Only would it be okay if I merge master into this branch, and later on we merge v4 into master (instead of rebase)? Due to the large number of commits, and because there are conflicts with master, rebasing can get difficult. I also took care to squash and merge the PRs, so we don't have tons of minor commits polluting the commit history.

holgerd77 · 2019-05-27T10:33:32Z

Ok, that sounds good!

I have merged master into v4. Should be ready for evaluation and merging 😄

holgerd77

Hooray!!! 🎉 🎉 🎉

This might still not be the optimal structure, but it will provide a much much more solid ground for all future work and comes with the most significant improvements this library has seen since I am involved in the project, thanks a lot Sina!!!

I've had a final look at all files, looks good.

Feel free to merge. 😄

no-1ne · 2019-05-27T15:47:24Z

Yay! can you also push the latest to npm pls

holgerd77 · 2019-05-27T17:09:15Z

@startupgurukul probably two days if nothing unexpected trigger a delay until a beta release on npm

holgerd77 · 2019-05-27T22:51:46Z

@s1na npm run testStatePetersburg is actually failing for me on master for all tests, even with a clean npm install + previously delete node_modules folder. Some example output:

$ npm run testStatePetersburg

> npm run build:dist && node ./tests/tester -s --fork='Petersburg' --dist

> ethereumjs-config-build

Any idea?

s1na · 2019-05-28T08:37:07Z

@holgerd77 Hmm 🤔 I tried on a fresh clone and the tests seem to pass. I wonder what could be the cause. Could you maybe add an console.log(err) here:

https://github.com/ethereumjs/ethereumjs-vm/blob/9f96231cf7b4b185368092416aa7af2c30d2f90b/lib/runTx.ts#L95-L96

to see if any error is occuring?

holgerd77 · 2019-05-28T09:27:55Z

@s1na Ah yes, great hint:

s1na · 2019-05-28T09:35:42Z

Maybe the typescript compiler hasn't overwritten previously built files. Could you try removing dist and then running the tests?

holgerd77 · 2019-05-28T09:39:04Z

Ah, yes, works: 😄
