[Parallel] Enable parallel on downgrade build on not started with ^(vendor|utils) by samsonasik · Pull Request #1621 · rectorphp/rector-src

samsonasik · 2022-01-04T12:47:36Z

@TomasVotruba this PR enabling parallel on downgrade build on directory list not start with ^(vendor|utils), with create extended config with enable parallel, because when directory list start with vendor or utils, it currently got notice error like in PR #1613 and #1610

I tested locally and it seems working ok:

All checks have passed 🎉 @TomasVotruba it is ready for review.

@TomasVotruba enabling vendor for parallel seems got the following error now:

I see. The parallel cannot be used in downgrade, as one process downgrades a /vendor file and the other process is already working with invalid type declarations.

We should upgrade the rector.php downgrade config to make it non-parallel.

TomasVotruba · 2022-01-04T13:56:42Z

I've merged the rectify PR, could you rebase on main?

samsonasik · 2022-01-04T13:57:29Z

@TomasVotruba rebased, I updated for more specific directory that need to be excluded in parallel process 2c46b1e

I added build/config/config-downgrade-parallel.php for parallel process, ref https://github.com/rectorphp/rector-src/pull/1621/files#diff-7818a393147bf199623465fc307c79e32fa62142018c0341644fb067fce670e4

Original build/config/config-downgrade.php is not parallel.

The script updated to not use parallel for the following directory started with:

(vendor/(symfony|symplify|rector)|src|utils)

ref https://github.com/rectorphp/rector-src/pull/1621/files#diff-f86931682f31678797031bd26cc05c1206f8bfc60fc66f4b9ef9a4ca46d5c596

I tried and it seems working.

samsonasik · 2022-01-04T14:02:06Z

All checks have passed 🎉 @TomasVotruba I think it is ready, let's give it a try?

TomasVotruba · 2022-01-04T14:16:54Z

build/downgrade-rector.sh

+    if [[ "$directory" =~ ^(vendor/(symfony|symplify|rector)|src|utils).* ]]; then
+        php -d memory_limit=-1 bin/rector process $directory --config build/config/config-downgrade.php --working-dir $BUILD_DIRECTORY --ansi
+    else
+        php -d memory_limit=-1 bin/rector process $directory --config build/config/config-downgrade-parallel.php --working-dir $BUILD_DIRECTORY --ansi
+    fi


I think we should keep the former single command, as this will be very confusing for anyone who wants to downgrade.

Ok, I will move config to variable.

I tried updated script to move to variable:

if [[ "$directory" =~ ^(vendor/(symfony|symplify|rector)|src|utils).* ]]; then config="build/config/config-downgrade.php" else config="build/config/config-downgrade-parallel.php" fi # --working-dir is needed, so "SKIP" parameter is applied in absolute path of nested directory php -d memory_limit=-1 bin/rector process $directory --config $config --working-dir $BUILD_DIRECTORY --ansi

it seems I got error on php 7.4:

➜ rector-build git:(downgrade-parallel) ✗ /opt/homebrew/Cellar/php@7.4/7.4.26_2/bin/php bin/rector -vvv --debug [ERROR] syntax error, unexpected 'private' (T_PRIVATE), expecting variable (T_VARIABLE)

probably I wrote something wrong in the script that possibly make variable not overriden in next iteration?

This is strange, still not work even with unset variable in end of each iteration:

for directory in $directories; do echo "[NOTE] Downgrading '$directory' directory\n" if [[ "$directory" =~ ^(vendor/(symfony|symplify|rector)|src|utils).* ]]; then CONFIG_PATH_DOWNGRADE="build/config/config-downgrade.php" else CONFIG_PATH_DOWNGRADE="build/config/config-downgrade-parallel.php" fi # --working-dir is needed, so "SKIP" parameter is applied in absolute path of nested directory php -d memory_limit=-1 bin/rector process $directory --config $CONFIG_PATH_DOWNGRADE --working-dir $BUILD_DIRECTORY --ansi unset CONFIG_PATH_DOWNGRADE done

TomasVotruba · 2022-01-04T14:48:54Z

I think this might be related to #1613 (comment)
It seems some classes are not loaded with static reflection, but with autoload and new downgraded content. That's why it's broken.

So we should fix that one first, then see if helps here.

samsonasik · 2022-01-04T14:51:13Z

It seems not working after rebase, even with if else direct:

    if [[ "$directory" =~ ^(vendor/(symfony|symplify|rector)|src|utils).* ]]; then
        php -d memory_limit=-1 bin/rector process $directory --config build/config/config-downgrade.php --working-dir $BUILD_DIRECTORY --ansi
    else
        php -d memory_limit=-1 bin/rector process $directory --config build/config/config-downgrade-parallel.php --working-dir $BUILD_DIRECTORY --ansi
    fi

samsonasik · 2022-01-04T15:08:40Z

It seems solved with set back Option::PARALLEL back to false when re-read config-downgrade.php 23340be

I updated the script to use variable config.

samsonasik · 2022-01-04T15:17:37Z

@TomasVotruba it works now 🎉🎉🎉

samsonasik · 2022-01-04T15:18:02Z

All checks have passed 🎉 @TomasVotruba I think it is ready.

samsonasik · 2022-01-04T15:23:16Z

Let's merge it for now to see the diff in the rector/rector as if it already different day, the diff is hard to see.

samsonasik · 2022-01-04T15:27:24Z

Ok, the script build/downgrade-rector.sh error:

config;vendor/phpstan/phpdoc-parser/src;vendor/symfony/dependency-injection;vendor/symfony/console;vendor/symfony vendor/psr;vendor/symplify vendor/nikic src;packages;vendor/ssch;rules;utils;bin rector.php;vendor/bin;vendor/clue;vendor/composer;vendor/cweagans;vendor/doctrine;vendor/ergebnis;vendor/evenement;vendor/helmich;vendor/idiosyncratic;vendor/myclabs;vendor/nette;vendor/react;vendor/rector;vendor/sebastian;vendor/tracy;vendor/webmozart
build/downgrade-rector.sh: 36: Syntax error: "(" unexpected (expecting "then")

which working ok locally.
