Server suddenly returns error code 500

It is found that the IO speed of the hard disk of the php-fpm process is 130Mb/s , and the corresponding file is /runtime/logs/app.log

Yii version 2.0.22
PHP version 7.1
Operating system linux


'log' => [
    'traceLevel' => YII_DEBUG ? 3 : 0,
        'targets' => [
            'class' => 'yii\log\FileTarget',
            'levels' => ['info','error', 'warning'],
            'logVars' => ['_GET','_POST'],//记录全局变量的参数,$_GET,$_SERVER...,默认会增加一条info记录
            'logFile' => '@app/runtime/logs/-app.log',
            'maxFileSize' => 1024 * 2000,       // 2G
            'maxLogFiles' => 1,

When I read the source code in vendor/yiisoft/yii2/log/FileTarget.php, I found that I should set rotateByCopy = false.


* @var bool Whether to rotate log files by copy and truncate in contrast to rotation by
* renaming files. Defaults to `true` to be more compatible with log tailers and is windows
* systems which do not play well with rename on open files. Rotation by renaming however is 
* a bit faster.
* The problem with windows systems where the [rename()](https://secure.php.net/manual/en/function.rename.php)
* function does not work with files that are opened by some process is described in a
* [comment by Martin Pelletier](https://secure.php.net/manual/en/function.rename.php#102274) in
* the PHP documentation. By setting rotateByCopy to `true` you can work
* around this problem.
public $rotateByCopy = true;

But I don't think this configuration will cause the server to stop serving.Then I found a bit of confusion.


    public function export()
        $logPath = dirname($this->logFile);
        FileHelper::createDirectory($logPath, $this->dirMode, true);

        $text = implode("\n", array_map([$this, 'formatMessage'], $this->messages)) . "\n";
        if (($fp = @fopen($this->logFile, 'a')) === false) {
            throw new InvalidConfigException("Unable to append to log file: {$this->logFile}");
        @flock($fp, LOCK_EX);   ########### lock file
        if ($this->enableRotation) {
        if ($this->enableRotation && @filesize($this->logFile) > $this->maxFileSize * 1024) {
            @flock($fp, LOCK_UN);   ########### unlock file
            $this->rotateFiles();   ########### when rotateByCopy = true , copying file content to aother file is slow (2GB size). Causes multiple php-fpm processes copy files at the same time
            ########### Why unlock file before rotateFiles() @see:https://github.com/yiisoft/yii2/pull/3563#issuecomment-425630598
            ########### Maybe we need a separate lock file for rotateFiles().
            // ...
        } else {
            // ...
        // ...

Is my idea right?

Im having some issue with Pjax
it seems to reregister a widgets Javascript
which calls the widget to be executed twice
The widget is called like:
public function init() {
   $this->view->registerJs(/* JS Code */, View::POS_READY, 'modalform');
and the view looks like:
    <?php \yii\widgets\Pjax::begin([ 'id' => 'pgrid' ]); ?>

                        <?= ModalForm::widget([ 
                                          //THIS IS THE WIDGET WITH DUPLICATED JS
                        ]); ?>

                        <?php $form = ActiveForm::begin(['method' => 'POST', 'options' => ['data-pjax' => true, 'class' => 'bmd-form-group bmd-form-group-sm']]); ?>
                                    <!-- ['inputOptions' => ['autofocus' => 'autofocus'] ] -->
                                    <?= $form->field($searchModel, 'query')->textInput( ['id' => 'inputField', 'placeholder' => 'Search records'])->label(false); ?>
                                    <?= Html::submitButton('<i class="material-icons">search</i>', [ 'class' => 'btn btn-rose btn-round btn-just-icon' ]); ?>
                            <?php ActiveForm::end(); ?>
                                $('#inputField').on('change', function(ev) {

                    <?= GridView::widget([]); ?>
So basically, there is a smart button that does a bunch of Javascript called ModalForm, a ActiveForm for searching and a GridView
when the ActiveForm is submitted, it triggers the PJax which reloads the GridView
problem is that the Pjax for some reason is deciding that the ModalForm widget needs its JS registered again
a really dirty temporary fix is simply to skip registering the JS if its Pjax request, but I feel like this isn't the most ideal solution to have in the widget controller.
if (! Yii::$app->request->isPjax)
    $this->view->registerJs(/* stuff */);

Hi everyone! How do I upgrade to bootstrap 4 in yii? Is there any helpful document that explains how to do so?

What is the best practice for using Access Tokens in apis?

        $identity = self::find()->where(['access_token' => $token])->select('id')->one();
        if ($identity == null) return null;

        //As per the recommendations, https://www.yiiframework.com/doc/api/2.0/yii-web-identityinterface#findIdentityByAccessToken()-detail
        // null should be re turned here.
        if (!Yii::$app->authManager->checkAccess($identity->id, Permissions::IdentifyWithAccessToken))
            return null;    

        return $identity;

this doesn't seem all that secure having it in plain text.

when the "Development Tools" chapter is going to be created, please?

Hi, I have two models that have a many to many relation. In the create action of the controller for model A I want to create an entry in the junction table to "link" model B. Yet I get the following error: UnknownPropertyException
This is how I call the linking after the $model was saved $model is an Organisation, organisationUsers is the junctiontable/model for linking organisations to users: $model->link('organisationUsers', Yii::$app->user->identity, ['status' => 10, 'role' => 10]);.
This is the next called method in the stack trace: in /app/vendor/yiisoft/yii2/db/BaseActiveRecord.php at line 1350– yii\db\BaseActiveRecord::bindModels(['organisation_id' => 'id'], common\models\User, common\models\Organisation).
in /app/vendor/yiisoft/yii2/db/BaseActiveRecord.php at line 1574– yii\db\BaseActiveRecord::__get('organisation_id')
Kai Mindermann, M.Sc.
Fixed it, I was using the junction table relation instead of the relation to users
qncm Hey. I'm populating dropdownlist for a nullable field. What should be the key here: [ ??? => 'nothing', ...]?

Any idea why would isGuest and user identity only works in SiteController and not other controllers?
Nouras Hamwi
isGuest works fine in frontend and backend but the problem is happenening when you add a third application I followed Yii2 documentation to create an additional application which works find just user identity is not working outside of sitecontroller.
How do I override the base MOdel class using DI?

I have tried

'container' => [
        'definitions' => [
            yii\base\Model::class => app\models\Model::class,

but that doesn't do anything. The models dont have any of the app\models\Model::class and are not instances of it

 $model = TestModel::findOne(['id' => 3]);
 $success = $model instanceof \app\models\Model;
  if (!$success) Yii::$app->session->addFlash('danger', 'failed to override');
this always fails

Hey guys, I have a question regarding the yiisoft/yii2-queue and the monitor extension from Roman Zhuravlev. I need to implement a worker affinity for jobs.

I start worker using supervisor in docker container (1 or many):


command=yii queue/listen --verbose=1 --php-binary=/usr/local/bin/php --isolate=1 --color=0 --interactive=0
stdout_logfile = /dev/stdout
stdout_logfile_maxbytes = 0
stderr_logfile = /dev/stderr
stderr_logfile_maxbytes = 0

So I have 5 isolated queue listeners up and running in each container / host.
Now a job A was pushed for the first time and gets executed by worker A on host A.
Then I remember (using a simple key value store in redis) that job A was processed by worker A on host A.
Works fine so far and I can access that information everywhere.

Now the next time job A comes I need to ensure that this job A will only gets executed on worker A on host A.
Until worker A on host A is busy that job A needs to wait.

I tried a lot to get that done but job A gets always executed by one of the next free available worker process.

I use own extended classes doing nothing atm then calling the parent class methods to be able to customize.
Here`s my config:

'queue' => [
            'class' => ProjectQueue::class,
            'commandClass' => ProjectCommand::class,
            'as log' => [
                'class' => ProjectLogBehavior::class,
                'autoFlush' => true,
            'as jobMonitor' => [
                'class' => ProjectJobMonitor::class,
            'as workerMonitor' => [
                'class' => ProjectWorkerMonitor::class,
            'mutex' => [
                'class' => MysqlMutex::class,
                'db' => 'db',
                'autoRelease' => false,
            'mutexTimeout' => 10,
            'db' => 'db',
            'channel' => 'master-queue', 
            'deleteReleased' => true, 
            'ttr' => 200,
            'attempts' => 1,

Now my question. Is that possible at all? And where I need to slide in to get that done.

Thanks in advance !
