Re: [PHP] Weird MySQL+Gearman issue - SOLVED
On Fri, Dec 14, 2012 at 7:41 AM, FeIn aci...@gmail.com wrote: Hi all, I have a typical web application that does some basic CRUD operations. Operations that modify the database (inserts, updates, deletes) trigger a background gearman job to refresh the cache that is used for another application. The problem is that when I do an update the gearman worker script (which has its own database connection) does not pick up the updates. For example if I were to update a row: UPDATE table SET rowname = 'updated value' WHERE rowid = 1, the respective row is updated correctly, but when the worker gets around to handle the job of refreshing the cache for that row the SELECT FROM table WHERE rowid = 1 picks up the older value (the one before the update). I activated the mysql log and the queries are definitely run in the correct order (first the update and the select on a another connection). Has anybody encountered this issue before? I should also mention that the worker is setup to run a certain number of cache refreshing jobs after which it will die, but it will use the same connection to do those jobs. If I force the worker to use a new connection for each job everything works fine, otherwise the update is picked up only for the first job but not for the subsequent jobs. Any ideas? Thanks in advance. The problem was on my side, and it had to with Doctrine's identity map. I cleared Doctrine's entity manager for every job handled by the Gearman worker and it seems that everything works fine now. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Yeah, like there's a standard for herding cats! [guffaw] Seriously, no I know of no such standards. It sounds like you're thinking of the kind of thing that's more common in languages like COBOL than anything modern. Plus, it's near impossible on any significantly sized project to segregate code in such a way. That said, I would recommend PHPDoc or similar. It's a package for generating code documentation from the comments embedded in your code. You adhere to certain conventions in the format of your comments, and PHPDoc can scan your code and produce pretty docs. Plus, the comments themself serve as a sort of discipline in explaining what functions and sections of code do. If you keep your functions to singular, small tasks (as you should), the comments are invaluable when you come back later to try to figure out what you were thinking when you wrote this or that block of code. I don't know how extensive your experience is with coding or PHP. So in case you're a relative newbie, I'd also suggest that you keep classes in their own files (one file per class) in a libraries directory or somesuch. In fact, I'd suggest downloading something like CodeIgniter, and studying the way they structure their code physically. They may not be the optimum example, but for a well-known framework, their code base is relatively slim and well-organized. Also, obviously, study the MVC (model-view-controller) paradigm. It's a very useful way of dividing up your code's functionality. Paul -- Paul M.
