Get ready for PHPStan 2.0

[ondrejmirtes]

Feature Request

Hi, I just started working on PHPStan 2.0 which will come with PHP-Parser 5. These are early days of the development, but you can already require phpstan/phpstan:^2.0 (with minimum-stability dev) and start working on making Rector compatible.

There will be more backward compatibility breaks coming in the next few months as I work towards to release, but you can already start getting rector-src ready for Rector 2.0 which will require PHPStan 2.0.

Please keep this issue open so we can discuss the next major PHPStan version. I'd also appreciate any feedback from your side. Thanks. 🤞

Sounds good 👍

We'll give this a priority by the end of the year and do upgrade of both PHPStan 2 and php-parser 5 at once.

We're now in the release candidate period phpstan/phpstan#11816

rector phpstan's extensions seems need to have compatible to phpstan 2 first:

  Problem 1
    - Root composer.json requires rector/type-perfect ^0.1.6 -> satisfiable by rector/type-perfect[0.1.6, 0.1.7, 0.1.8].
    - rector/type-perfect[0.1.6, ..., 0.1.8] require phpstan/phpstan ^1.11 -> found phpstan/phpstan[1.11.0, ..., 1.12.x-dev] but it conflicts with your root composer.json require (^2.0).
  Problem 2
    - Root composer.json requires symplify/phpstan-extensions ^11.4 -> satisfiable by symplify/phpstan-extensions[11.4.0, 11.4.1, 11.4.2, 11.4.3].
    - symplify/phpstan-extensions[11.4.0, ..., 11.4.3] require phpstan/phpstan ^1.10 -> found phpstan/phpstan[1.10.0, ..., 1.12.x-dev] but it conflicts with your root composer.json require (^2.0).
  Problem 3
    - Root composer.json requires symplify/phpstan-rules ^13.0 -> satisfiable by symplify/phpstan-rules[13.0.0, 13.0.1].
    - symplify/phpstan-rules[13.0.0, ..., 13.0.1] require phpstan/phpstan ^1.10.30 -> found phpstan/phpstan[1.10.30, ..., 1.12.x-dev] but it conflicts with your root composer.json require (^2.0).
  Problem 4
    - Root composer.json requires tomasvotruba/unused-public ^0.3.10 -> satisfiable by tomasvotruba/unused-public[0.3.10, 0.3.11].
    - tomasvotruba/unused-public[0.3.10, ..., 0.3.11] require phpstan/phpstan ^1.10.19 -> found phpstan/phpstan[1.10.19, ..., 1.12.x-dev] but it conflicts with your root composer.json require (^2.0).
  Problem 5
    - Root composer.json requires phpstan/phpstan-phpunit ^1.4 -> satisfiable by phpstan/phpstan-phpunit[1.4.0, 1.4.x-dev].
    - phpstan/phpstan-phpunit 1.4.0 requires phpstan/phpstan ^1.11 -> found phpstan/phpstan[1.11.0, ..., 1.12.x-dev] but it conflicts with your root composer.json require (^2.0).
    - phpstan/phpstan-phpunit 1.4.x-dev requires phpstan/phpstan ^1.12 -> found phpstan/phpstan[1.12.0, ..., 1.12.x-dev] but it conflicts with your root composer.json require (^2.0).

@TomasVotruba Today is 11.11. Do you plan to make Rector PHPStan 2 compatible this week?

[samsonasik]

First step: symplify/phpstan-extensions#12

[TomasVotruba]

@szepeviktor Depends how many only-in-Rector BC breaks we'll have to deal with. We use lot of internal code, so it might be a challange.

@samsonasik Could you look into it? rector/rector first, so we can keep it focused on single repository

[samsonasik]

@TomasVotruba sure, phpstan 2 require php-parser 5 so it will need revisit my old PR:

• Try php-parser:dev-master (5-dev) rector-src#2916

to be reincorporated ;)

I think best way to start is to enable bleeding edge and maybe install phpstan-deprecation-rules and start fixing stuff that pops up. We don't need to require 2.0 for that.
