php - Assetic is generating multiple files with same content -

i have class uses assetic generate css files disk. i'll jump right code.

in layout header, i'm doing this:

$assetify = new assetify();   $assetify->setdebug(true); $assetify->setassetdirectory(base_dir . '/public/assets'); $assetify->setoutputdirectory(base_dir . '/public/assets/generated'); $assetify     ->addstylesheet('/assets/css/bootstrap-2.3.2.css')     ->addstylesheet('/assets/css/select2-3.4.3.css')     ->addstylesheet('/assets/css/main.css');  echo $assetify->dump(); 

my "assetify" class runs through assetic. i'll paste hope relevant portions dump() function:

// asset factory allows not have hard work ourselves. $factory = new assetfactory($this->assetdirectory, $this->debug); $factory->setdefaultoutput('/generated/*.css');  // filter manager allows organize filters asset handling. // other filters, see: https://github.com/kriswallsmith/assetic $fm = new filtermanager(); $fm->set('yui_css', new yui\csscompressorfilter('/usr/local/bin/yuicompressor-2.4.7.jar')); $fm->set('yui_js', new yui\jscompressorfilter('/usr/local/bin/yuicompressor-2.4.7.jar')); $factory->setfiltermanager($fm);  // asset manager allows keep our assets organized. $am = new assetmanager(); $factory->setassetmanager($am);  // cache-busting worker prefixes every css amounts version number. $factory->addworker(new cachebustingworker());  $assetcollection = array(); foreach ($assetgroups $assetgroup) {     foreach ($assetgroup $media => $items) {         $filecollection = array();         foreach ($items $item) {             // add asset asset collection.             $filecollection[] = new fileasset($item);         }         $assetcollection[] = new assetcollection($filecollection);     } }  $assetcollection = new assetcollection($assetcollection); $am->set('base_css', $assetcollection);  // generate required assets. prefixing filter name question mark // cause filter omitted in debug mode. $asset = $factory->createasset(     array('@base_css'),     array('?yui_css') );  // configure internal file system cache don't regenerate file on every load. $cache = new assetcache(     $asset,     new filesystemcache($this->outputdirectory) );  // , generate static versions of files on disk. $writer = new assetwriter($this->assetdirectory); $writer->writeasset($cache); 

this generates 2 different files, 87229eb-f47a352.css , a37c1589762f39aee5bd24e9405dbdf9. contents of files same. 87229eb-f47a352.css file seems generated every single time, , other file not regenerated unless contents of files change (this like). if comment out $writer->writeasset($cache), no files written disk.

what obvious configuration missing? appreciate help, thank you.

i able replicate code , got same results.

i trying same results think require ended writing own code cache , serve static files.

it's not complete means working. has following features:

• you can choose cache files different pages if specify $filename
• you can choose create versions of released files or delete previous versions
• a cached file generated target folder if changes have made source file
• you need put code in class or function , return url serve.

hope helps :)
