maintenance

I'm looking for a solution that will allow my rails app to render a user-friendly maintenance page when there is no Mysql server available to connect to. Normally a Mysql::Error is thrown from the mysql connection adapter in active_record Something like: /!\ FAILSAFE /!\ Wed May 26 11:40:14 -0700 2010 Status: 500 Internal Server Error Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock Is there a low-overhead way to catch this error and render a maintenance page instead? I'm assuming that since connections are actually made in the active_record mysql adapter the app

I try to set up a maintenance page with ZF2 but it's not working. I put a maintenance.html page in public folder (www) and in my onbootstrap function I've got the following code : $config = $e->getApplication()->getServiceManager()->get('Appli\Config'); if($config['maintenance']) { $response = $e->getResponse(); $response->getHeaders()->addHeaderLine('Location', '/maintenance.html'); $response->setStatusCode(503); return $response; } I enter the if cause $config['maintenance'] is true but it's not displaying my maintenance.html page as expected. Instead it displays the page asked. Is there

I just started this new job, where as the designer I have to maintain the CSS file for our web app. Right now it spans almost 7000 lines, weights over 160kb and has hundreds of !important rules. I would like to reorganize the file, split it into sub sections, clean it, and homogenize its syntax. But it seems like a huge undertaking and the file and the app are so big and complex that I wonder if it is even doable without breaking something (and not seeing it). I have audited the file using online tools, and it seems I can use some sort of automated refactoring without risking too much. I have

This came about mainly due to answers to SQL questions. UDF's and Sub Queries are intentionally omitted because of performance. I didn't include reliability not that it should be taken for granted, but the code has to work. Does performance always come first? So many answers are provided with performance as the main priority. My users seem to be more concerned with how quickly the code can be modified. So a report takes 15 seconds instead of 12 to run. They can live with that as long as I'm not making excuses for not providing solutions. Obviously if the 15 seconds turns into 15 minutes, there

This may be a subjective question leading to deletion but I would really like some feedback. Recently, I moved to another very large enterprise project where I work as a developer. I was aghast to find most classes in the project are anywhere from 8K to 50K lines long with methods that are 1K to 8K lines long. It's mostly business logic dealing with DB tables and data management, full of conditional statements to handle the use cases. Are classes this large common in large enterprise systems? I realize without looking at the code it's hard to make a determination, but have you ever worked on a
