From 46e1a24cc5272072d0db858b7e868f61a42d88a4 Mon Sep 17 00:00:00 2001 From: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> Date: Thu, 23 Jul 2026 20:46:34 +0000 Subject: [PATCH 01/22] Implement worker console message output alongside ProgressBar - Add ParallelWorker::write() and ParallelWorker::writeln() methods. - Route messages through ProgressBarWorker when a progress bar is active (clear/write/display). - Add a ConsoleWorker fallback for workers without a progress bar. - Use a shared stderr OutputInterface so ProgressBar and messages share the same stream. - Add WriteOutputMessage command and ConsoleWorker/HasChannels infrastructure. - Update README and CHANGELOG.

PHP_EOL : '')); +} + +final public function writeln(string $message): void { + $this->write($message, true); +} +``` + +Notes: + +- If a progress bar is active, the message is serialized through the existing channel to the `ProgressBarWorker` thread. +- If no progress bar is active but a console channel is connected, the message is routed to `Runner` (or a console worker it spawned). +- If neither is available, the worker writes directly to `STDERR` as a last resort. + +### 4. ProgressBarWorker + +`src/Internals/ProgressBarWorker.php` + +```php +private function writeOutput(string $message, bool $newline = true): void { + $this->progressBar->clear(); + $this->output->write($message, $newline); + $this->progressBar->display(); +} +``` + +This performs the exact sequence described in the issue: hide the bar, print the message, then redraw the bar so it recalculates its cursor position. + +### 5. ProgressBarWorker trait + +`src/Internals/ProgressBarWorker/HasProgressBar.php` + +Store the same `OutputInterface` that `ProgressBar` will use. `ProgressBar` switches a `ConsoleOutput` to its error output, so both the bar and messages end up on `stderr`: + +```php +use Symfony\Component\Console\Output\ConsoleOutput; +use Symfony\Component\Console\Output\OutputInterface; + +trait HasProgressBar { + + private ProgressBar $progressBar; + private bool $progressBarStarted = false; + private OutputInterface $output; + + private function createProgressBar(): void { + $this->output = (new ConsoleOutput())->getErrorOutput(); + $this->progressBar = new ProgressBar($this->output); + + // existing configuration stays unchanged + $this->progressBar->setBarWidth(80); + $this->progressBar->setRedrawFrequency(100); + $this->progressBar->minSecondsBetweenRedraws(0.1); + $this->progressBar->maxSecondsBetweenRedraws(0.2); + $this->progressBar->setFormat(format: + "%current% of %max%: %message%\n". + "[%bar%] %percent:3s%%\n". + "elapsed: %elapsed:6s%, remaining: %remaining:-6s%, %items_per_second% items/s"."...". + "memory: %threads_memory%\n"); + + $this->progressBar->setMessage('Starting...'); + $this->progressBar->setMessage('??', 'items_per_second'); + $this->progressBar->setMessage('??', 'threads_memory'); + } + +} +``` + +`ProgressBar` receives the `stderr` `OutputInterface` directly, so both the bar and `write()` messages render on `stderr`. + +### 6. Sequential fallback + +`src/Internals/Runner/ManagesTasks.php` + +The closures that forward messages to local handlers are currently typed as `ProgressBarActionMessage`. They need to accept any `ParallelCommandMessage`: + +```php +// for workers with a progress bar +$worker->connectProgressBar(fn(Commands\ParallelCommandMessage $message) => $this->progressBar->processMessage($message)); + +// for workers without a progress bar +$worker->connectConsole(fn(Commands\ParallelCommandMessage $message) => $this->writeOutput($message)); +``` + +`Runner::writeOutput()` would simply write to its local `ConsoleOutput`'s error output (no `clear()`/`display()` needed when no progress bar is active). + +### 7. Fallback for workers without a progress bar + +For workers that do **not** call `withProgress()`, `write()` should still be coordinated so messages are not lost in a multi-threaded run. `Runner` spawns a dedicated `ConsoleWorker` thread that owns the fallback `ConsoleOutput`; `ParallelWorker` routes messages to it when no progress bar channel is connected. + +Design: + +- `Runner` creates a dedicated console output channel (e.g. `ConsoleWorker::class.'@'.$uuid`) and spawns a `ConsoleWorker` thread. +- `ConsoleWorker` listens on that channel and writes each `WriteOutputMessage` to the `stderr` `OutputInterface` from its own `ConsoleOutput`. +- `ParallelWorker` connects to the console channel via `connectConsole(string $uuid)` when it starts. +- In sequential fallback, `ManagesTasks` passes a closure to `connectConsole()` that writes through `Runner`'s own `ConsoleOutput`. + +```php +final public function write(string $message, bool $newline = false): void { + $message = new Commands\ProgressBar\WriteOutputMessage($message, $newline); + + if ($this->progressbar_channel !== null) { + // route through ProgressBarWorker + if (PARALLEL_EXT_LOADED) { + $this->progressbar_channel->send($message); + } else { + ($this->progressbar_channel)($message); + } + + return; + } + + if ($this->console_channel !== null) { + // route to ConsoleWorker fallback + if (PARALLEL_EXT_LOADED) { + $this->console_channel->send($message); + } else { + ($this->console_channel)($message); + } + + return; + } + + // last resort + fwrite(STDERR, $message.($newline ? PHP_EOL : '')); +} +``` + +`connectConsole(string $uuid)` (or a closure in sequential mode) sets `$this->console_channel`, analogous to `connectProgressBar()`. + +### 8. ConsoleWorker + +`src/Internals/ConsoleWorker.php` + +A new worker thread that owns the fallback output and listens for `WriteOutputMessage`s: + +```php +output = (new ConsoleOutput())->getErrorOutput(); + } + + public function afterListening(): void { + // close the console output channel + } + + private function writeOutput(string $message, bool $newline = true): void { + $this->output->write($message, $newline); + } + +} +``` + +`Runner` creates the channel and starts this thread in the same way it starts `ProgressBarWorker`. + +## Behaviour + +### With a progress bar + +When `write()` is called in a worker that has `withProgress()` enabled: + +1. The worker thread sends a `WriteOutputMessage` through the progress bar channel. +2. The `ProgressBarWorker` thread receives it, calls `clear()` to erase the bar, writes the message line to `stderr` via the same `OutputInterface`, then calls `display()` to redraw the bar below the message. + +Because all ProgressBar actions are already processed sequentially through the channel, the `clear`/`write`/`display` sequence is atomic with respect to other bar updates. + +### Without a progress bar + +When `write()` is called in a worker that does **not** have `withProgress()` enabled: + +1. The worker thread sends a `WriteOutputMessage` through the console fallback channel. +2. The `ConsoleWorker` thread receives it and writes the message line to `stderr`. + +There is no `clear()`/`display()` because no progress bar is active. + +## Example + +Scheduler code: + +```php +Scheduler::using(LogWorker::class) + ->withProgress(steps: 10); + +foreach (range(1, 10) as $i) { + Scheduler::runTask($i); +} + +Scheduler::awaitTasksCompletion(); +``` + +Worker: + +```php +final class LogWorker extends ParallelWorker { + + protected function process(int $number = 0): int { + $this->setMessage("Task #{$number}"); + $this->writeln("Starting task #{$number}"); + + usleep(100_000); + + $this->writeln("Finished task #{$number}"); + $this->advance(); + + return $number; + } + +} +``` + +Expected terminal flow: + +``` +Starting task #1 + 1 of 10: Task #1 + [=====>---------------------------------------------] 10% + ... +Finished task #1 + 2 of 10: Task #2 + [=========>-----------------------------------------] 20% +``` + +## Backwards compatibility + +- `write()` and `writeln()` are added to the `ParallelWorker` abstract class via the `CommunicatesWithProgressBarWorker` trait, not to the `Contracts\ParallelWorker` interface. This avoids a BC break for any code that implements the interface directly. +- No existing methods are changed or removed. + +## Alternatives considered + +1. **Pass a `ConsoleOutput` object from `Runner` into workers** + - Not possible with `ext-parallel` because the output wraps stream resources. + - Sending message payloads to a `ConsoleOutput` owned by `Runner` (or a worker it spawns) is valid and is the chosen fallback. + +2. **Use `echo`/`fwrite` in the worker and pause the ProgressBar** + - The bar still overwrites the message on its next refresh because the cursor logic is unaware of the extra line. + +3. **Use `ConsoleOutput->section()`** + - More robust long-term, but requires a larger rewrite of `HasProgressBar` and coordination of multiple `ConsoleSectionOutput` instances. + - Symfony's `ProgressBar` supports section outputs, but the SDK currently uses a plain `ConsoleOutput`. This could be a future enhancement. + +4. **Single `writeMessage(string $message)` instead of `write`/`writeln`** + - Rejected in favor of Symfony's `write()` + `writeln()` naming. + +## Decisions made + +- **Naming:** Use Symfony `OutputInterface` naming: `write()` + `writeln()`. +- **Memory stats:** Do not update memory stats on `write()`. +- **Output stream for progress-bar workers:** Use the same `stderr` stream as `ProgressBar` for messages. `ProgressBar` switches a `ConsoleOutput` to its error output; we use that same `OutputInterface` for `write()`. +- **Output injection:** Out of scope for this RFC. +- **Fallback:** For workers without a progress bar, route messages to the `stderr` `OutputInterface` from a `ConsoleOutput` owned by a `ConsoleWorker` thread spawned by `Runner`. A last-resort `fwrite(STDERR)` remains only when no coordinator is available. + +## Known caveats + +- None currently; messages and the progress bar share `stderr`, so `clear()`/`write()`/`display()` work as Symfony intended. + +## Recommended next steps + +1. Implement the approved design. +2. Add PHPUnit tests for both the progress-bar path and the non-progress-bar fallback path. +3.
