What is browscap

browscap provides a database which can be used to find browser info if we have user agent.

$filesystem = new \League\Flysystem\Filesystem($fileCache);
$cache = new \MatthiasMullie\Scrapbook\Psr16\SimpleCache(

);

$logger = new \Monolog\Logger('name');

How to find cache directory

Need two steps to set up cache directory. Use --cache flag to specify cache directory. For the following set up, cache directory is /var/src/__cache

• vendor/bin/browscap-php browscap:fetch
• vendor/bin/browscap-php browscap:convert --cache /var/src/__cache

If see the error below, do two steps above again and make sure $cacheDir is the same as what specify in step 2.

there is no active cache available, please use the BrowscapUpdater and run the update command

Slove BrowscapPHP\Exception: there is no active cache available, please use the BrowscapUpdater and run the update

$cacheDir = APP_ROOT . '/composer/__cache';
$fileCache = new \League\Flysystem\Local\LocalFilesystemAdapter($cacheDir);
$filesystem = new \League\Flysystem\Filesystem($fileCache);
$cache = new \MatthiasMullie\Scrapbook\Psr16\SimpleCache(
    new \MatthiasMullie\Scrapbook\Adapters\Flysystem($filesystem)
);

$logger = new \Monolog\Logger('name');

//run these two lines once and the problem is gone
// $bc = new \BrowscapPHP\BrowscapUpdater($cache, $logger);
//$bc->update(\BrowscapPHP\Helper\IniLoaderInterface::PHP_INI_FULL);

$bc = new \BrowscapPHP\Browscap($cache, $logger);

Mysql docker container not working

One day, all of sudden, Mysql db in my local does not work. I am using mysql docker container. Check docker container status, I can see it restarts continuely. Look at docker-compose file, and I see this line

restart: on-failure

Ok, it restarts because of failure. Try to container log

docker logs -f  docker_mysql_1

There is a line in log

InnoDB: Error number 28 means 'No space left on device'

Ah, run of space. Here is how to solve this problem

• list all dangling volumes

  docker volume ls -qf dangling=true

• remove these volues

  docker volume rm $(docker volume ls -qf dangling=true)

• restart container

Before delete the volume, you can check which containers are using it

docker ps -a --filter volume=VOLUME_NAME

Find container details

docker container inspect container_id
