  • Format MySQL code inside PHP string

    - by JohnA
    Is there any program IDE or not that can format MySQL code inside PHP string e.g. I use PHPStorm IDE and it cannot do it. It does that for PHP and MYSQL but not for MYSQL inside php string. I am ready to use new IDE because now i have to manually format hundreds of database requests that are one line and not readable. Only criteria for my choice is that ide can do that automatically. <?php ... $request1 = "select * from tbl_admin where admin_id= {$_SESSION['admin_id']} and active= 1 order By admin_id Asc"; ... ?> should become <?php ... $request1 = "SELECT * FROM tbl_admin WHERE admin_id = {$_SESSION['admin_id']} AND active = 1 ORDER BY admin_id ASC"; ... ?>

  • New thread per client connection in socket server?

    - by Olaseni
    I am trying to optimize multiple connections per time to a TCP socket server. Is it considered good practice, or even rational to initiate a new thread in the listening server every time I receive a connection request? At what time should I begin to worry about a server based on this infrastructure? What is the maximum no of background threads I can work, until it doesn't make any sense anymore? Platform is C#, framework is Mono, target OS is CentOS, RAM is 2.4G, server is on the clouds, and I'm expecting about 200 connection requests per second.

  • Can a plain servlet be configured as a seam component?

    - by stacker
    I created a plain servlet within a seam-gen (2.1.2) application, now I would like to use injection. Thus I annotated it with @Name and it's recognized as component: INFO [Component] Component: ConfigReport, scope: EVENT, type: JAVA_BEAN, class: com.mycompany.servlet.ConfigReport Unfortunatly the injection of the logger doesn't work NullPointerException in init() import org.jboss.seam.annotations.Logger; import org.jboss.seam.annotations.Name; import org.jboss.seam.log.Log; @Name("ConfigReport") public class ConfigReport extends HttpServlet { @Logger private Log log; public void init(ServletConfig config) throws ServletException { log.info( "BOOM" ); } } Is my approach abusive? What would be the alternatives (the client sending requests to the servlet is curl, not a browser)?

  • Updating a module level shared dictionary

    - by Vishal
    Hi, A module level dictionary 'd' and is accessed by different threads/requests in a django web application. I need to update 'd' every minute with a new data and the process takes about 5 seconds. What could be best solution where I want the users to get either the old value or the new value of d and nothing in between. I can think of a solution where a temp dictionary is constructed with a new data and assigned to 'd' but not sure how this works! Appreciate your ideas. Thanks

  • Rails 2.3.5: flash[:notice] disappears after redirect_to call

    - by xyzman
    Here I've got two controller methods: def invite if request.post? begin email = AccountMailer.create_invite(@user,url) AccountMailer.deliver(email) flash[:notice] = "Invitation email sent to #{@user.email}" rescue #mail delivery failed flash[:error] = "Failed to deliver invitation" end redirect_to :action => :show, :id => @user.id end end and def show @title = "User #{@user.full_name}" end The problem is, when I send an invitation, and get redirected to ./show, I see no messages at all. If I change redirect_to to render, the message appears. Still, isn't it intended for flash to work in the immediate subsequent requests? BTW, I'm using Rails+Passenger setup, could it be so that redirected request goes to another application instance?

  • Jquery JSON .each() doesnt work in Google Chrome

    - by Sheriffen
    I have a really simple chat application on a site which works pretty good. It requests by ajax like this: $.ajax({ url: "fetch/"+CHAT_SESSION_ID+"/"+LAST_MESSAGE_ID, dataType: "json", cache: false, success: function(data) { if (data.session_active == 0) { //If other chatter ended session alert("Session Ended"); } else { $.each(data.messages, function(i,msg){ alert(msg.message.Body); )}; } } }); and gets a json response that lookes like this: { "session_active": "1", "messages": [ {"message": {"MsgID": "100", "UserID": "1", "Body": "heyy"}}, ]} It works really well in at least FF and Saf but in Chrome it never gets past the .each! This is driving me nuts, have tried everything I've come across online for days but I can't seem to get it right. Please someone help! I can provide testserver if someone wants to firebug it themselves ;)

  • Should I allow my clients to open tickets/access trac?

    - by Mark
    I just installed trac for this project I'm working on, since it's turned out to be a bit bigger than I anticipated. I've added a bunch of tickets with my clients requests which come in the form of emails, phone calls, and meetings. I've also added some stuff I know needs to be done/fixed but they haven't specifically requested. Should I grant them access to trac so they can submit the tickets themselves so I don't have to keep translating (words into tickets) for them? They're very non-technical, so I'm not sure how well it would work; they might open tickets and not provide enough detail, or get confused by all the different fields. If your answer is "no", should I at least let them view the tickets, so they can see what I'm working on, what's been done, hasn't been done? So they can stop calling me to say "xxx doesn't work" when it's already a ticket? (Not that this would work, but I could at least respond "see ticket #42")

  • php most memory efficient way to return files

    - by bumperbox
    so i have a bunch of files, some can be up to 30-40mb and i want to use php to handle security of the files, so i can control who has access to them that means i have a script sort of like this rough example $has_permission = check_database_for_permission($user, filename); if ($has_permission) { header('Content-Type: image/jpeg'); readfile ($filename); exit; } else { // return 401 error } i would hate for every request to load the full file into memory, as it would soon chew up all the memory on my server with a few simultaneous requests so a couple of questions is readfile the most memory efficient way of doing this? is there some better method of achieving the same outcome, that i am overlooking? server: apache/php5 thanks

  • Jmeter Query new user

    - by Sri
    First of all apologies for the below question. Am from a Testing background for the past 8 years and very novice to Jmeter. I went through the Jmeter site, and ran a sample recording using the jmeter.apache.org site and it went fine. I want to test my knowledge and understanding. So, I did the following way. Created a thread group. Added a config element HTTP Default Requests with server name as mail.google.com. Added a Sampler as HTTP request, set the METHOD to POST and gave the username and password, and i ran the test. When i see the Results Viewer, i could see the login page of gmail, I need to know how to pass my username and password and simulate the clicking of Submit button and getting the next page. Please help, am very new and will really appreciate if it's explained as simple as possible.

  • Co-opt popular abandonware opensource project? Thoughts?

    - by Mike Bouck
    Here's the scenario: A popular open source project is used/loved by many but has become stale due to the fact that the last drop came out nearly a year ago. Many bugs/feature requests/fixes have been logged in the interim and everyone is getting by via downloading the trunk and building custom/private builds with the changes incorporated. The copyright is simple -- there is none and the code is in the public domain. The project owner spins the project as community open source and has setup a sourceforge site, but to date (5 years running now) has yet to accept one contributor. In otherwords the "community" is a community of one. The project owner takes great pride in the project and has obviously contributed a lot of time/effort but for whatever reason has has seemingly abandoned the project and is unresponsive when offers of help are made. So, the question, should the community fork the codebase, setup a new community site, and take matters in their own hands?

  • how to make an array of arrays

    - by yuliya
    hi, how would you write an array of values to other array. In instance, I have a list of IPs and list of requests. I want to have something like [{ip1, request1}, {ip2, request2}, ....]. It's how I would do it, but sure obj will change every time and array will have all the time the same values. ArrayList array = new ArrayList(); Object[] obj = new Object[2]; for (int i=0; i<listSize; i++){ obj[0] = ipList.get(i).toString(); obj[1] = requestList.get(i); array.add(obj);

  • Maintaining traceability up-to-date as project evolves

    - by Catalin Piti?
    During various projects, I needed to make sure that the use case model I developed during the analysis phase is covering the requirements of the project. For that, I was able to have some degree of traceability between requirement statements (uniquely identified) and use cases (also uniquely identified). In some cases, enabling traceability implied some additional effort that I considered (and later proved) to be a good investment. Now, the biggest problem I faced was to maintain this traceability later, when things started to change (as a result of change requests, or as a result of use case changes). Any ideas of best practices for traceability maintenance? (It can apply to other items in the project - e.g. use cases and test cases, or requirements and acceptance test cases) Later edit Tools might help, but they can't detect gaps or errors in traceability. Navigation... maybe, but no warranty that the traceability is up-to-date or correct after applying the changes.

  • Will lock() statement block all threads in the proccess/appdomain?

    - by MikeJ
    Maybe the question sounds silly, but I don't understand 'something about threads and locking and I would like to get a confirmation (here's why I ask). So, if I have 10 servers and 10 request in the same time come to each server, that's 100 request across the farm. Without locking, thats 100 request to the database. If I do something like this: private static readonly object myLockHolder = new object(); if (Cache[key] == null) { lock(myLockHolder) { if (Cache[key] == null) { Cache[key] = LengthyDatabaseCall(); } } } How many database requests will I do? 10? 100? Or as much as I have threads?

  • How can I view the all inherited url-resolution rules affecting a given directory?

    - by john.designop.us
    I work on two sites hosted on the same server, using the same CMS configurations and identical .htaccess files in their respective document roots. One site is letting me use the CMS's clean-url mode, and the other isn't. Site #2 functions fine in ?=messy-url mode, but when I turn clean urls on in the admin panel, and request a rewritten URL, I get a 404 error served before the CMS sees the request. I've contacted the server administrator, but he isn't inclined to provide support and the site owners are beholden to this hosting provider. I have shell access to the Linux-based server, and I can verify that mod_php and mod_rewrite are active, but I don't know what more I can do to troubleshoot this issue. Is there any way to identify directives upstream that may be differentiating the way http requests are handled by the two sites? Thanks!

  • How to to dump JS array... (boommarklet?)

    - by Soulhuntre
    A page on a site I use is holding some of my data hostage. Once I have logged into the site and navigated to the right page, the data I need is in the array eeData[] - it is 720 elements long (once every 2 minutes of a given day). Rather than simulate the requests to the underlying stuff json supplier and since its only once a day, I am happy to simply develop a bookmarklet to grab the data - preferably as a XML or CSV file. Any pointers to sample code or hints would help. I found a bookmarklet here that is based on this script that does part of this - but I am not up to speed on any potential JS file IO to see if it is possible to induce a file "download" of the data, or pop it opn in a new window I can copy / paste.

  • Class design question (Disposable and singleton behavior)

    - by user137348
    The Repository class has singleton behavior and the _db implements the disposable pattern. As excepted the _db object gets disposed after the first call and because of the singleton behavior any other call of _db will crash. [ServiceBehavior(InstanceContextMode=InstanceContextMode.Single)] public class Repository : IRepository { private readonly DataBase _db; public Repository(DataBase db) { _db = db; } public int GetCount() { using(_db) { return _db.Menus.Count(); } } public Item GetItem(int id) { using(_db) { return _db.Menus.FirstOrDefault(x=>x.Id == id); } } } My question is, is there any way to design this class to work properly without removing the singleton behavior? The Repositoryclass will be serving big amount of requests.

  • RSS feed per tag

    - by niaher
    Hi. Suppose stackoverflow.com wanted to have an RSS feed per each tag. They would probably have requests like stackoverflow.com/rss?tag=aspnet to return appropriate RSS feeds. This is the easy part. Now when the user requested stackoverflow.com/rss?tag=aspnet he would see some XML. Instead it would be better to show a page where user can choose which RSS reader he wants to subscribe with (just like feedburner.com). My question is: is there any ready-made code (html+javascript) that I can copy-paste to create such a subscription page? Basically I want to copy feedburner.com's subscription page onto my own site. PS - I would be happy using feedburner.com, but it would require me to create a feed for each tag manually, which is impractical.

  • Offline navigation software for Android - what is out there?

    - by Ted
    Im looking for navigation software for the Android platform and I have a few requirements: Offline maps. The maps should be stored on the device/memory card so no Internet-connection is required There should be some way to interact with the application "through code"; sending route requests, getting current location perhaps, bringing app to foreground/background, etc. An API so it can be controlled from another application. No monthly fees The only one I found so far to match the above is Sygic Navigation. However, I havent yet been able to communication with the app even though they say that it can be done. Still investigating that...

  • Password protect web pages on Windows CE 6

    - by Chris
    I am using the default web server for WinCE 6 and wish to password protect certain folders. The default VROOT /remoteadmin/ is password protected, and this works but my configuration doesn't work. I have tried mimicking these settings on my own folders but to little success. Here is how one looks: In the HKLM\Comm\HTTPD\VROOTS key I have created a subkey called /web/configuration (this folder actually exists on the box). The following values are in this key A = 1 DefaultPage = config.html Path = /hard disk/webroot/web/configuration/ UserList = ADMIN This is nigh on identical to the settings in /RemoteAdmin/ but /RemoteAdmin/ requests a password and /web/configuration doesn't (even after reboot).

  • Content cacheing with PHP and CodeIgniter

    - by Josh K
    I have a couple of things I'm working on, namely a page that issues five or six cURL requests and processing content on them. I'm working with CodeIgniter on a LAMP stack but am open to other options. Naturally I would prefer to not rewrite the application. I would like to know if there are any ready-made / easily learned caching methods. Primarily I'd like to check if the page has changed since I last scrapped it. If it has, redownload and present. If it hasn't, serve up a cached copy.

  • running code when two events have triggered

    - by Evert
    This is mostly a language-agnostic question. If I'm waiting for two events to complete (say, two IO events or http requests), what is the best pattern to deal with this. One thing I can think of is the following (pseudo js example). request1.onComplete = function() { req1Completed = true; eventsCompleted(); } request2.onComplete = function() { req2Completed = true; eventsCompleted(); } eventsCompleted = function() { if (!req1Completed || !req2Completed) return; // do stuff } Is this the most effective pattern, or are there more elegant ways to solve this issue?

  • How do I rewrite a request by hostname unless it is a specified value?

    - by Tim
    My app will have a regular domain - let's say example.com - which will have information about logging in, signing up, etc. It will also host numerous other domains dynamically. My app serves the webpage for these at http://example.com/site/foobar.com/ So, I need to redirect all requests where the hostname is not example.com to /site/[hostname]/ I'm writing this in Django and hosting with Apache. How do I set up a rewrite rule to do this? The user must not know they are on any other site but foobar.com and if the user browses to foobar.com/something - the URL must be rewritten to /site/foobar.com/something

  • Using Javascript to detect the bottom of the window and ignoring all events when a request is loading

    - by Aaron Reba
    I have an anonymous function to detect the user has scrolled to the bottom of the window. Inside of the anonymous function, I have a call to a database that takes a while to complete. var allowing_more = 1; $(window).scroll(function() { if (allowing_more == 1){ if ($(window).scrollTop() + $(window).height() == $(document).height()) { allowing_more = 0; //query allowing_more = 1; } } }); In this time, if the user scrolls to the bottom of the window again, it seems a queue is made holding the occurences the user scrolled to the bottom of the window while the query was loading. Upon completing of the query, these occurences are then executed. I have a boolean statement to detect if the anonymous function is accepting more query requests but this seems to be ignored. Is there some sort of way to ignore an anonymous function temporarily and re-enable it?

  • Azure Service Bus Scalability

    - by phebbar
    I am trying to understand how can I make Azure Service Bus Topic to be scaleable to handle 10,000 requests/second from more than 50 different clients. I found this article at Microsoft - http://msdn.microsoft.com/en-us/library/windowsazure/hh528527.aspx. This provides lot of good input to scale azure service bus like creating multiple message factories, sending and receiving asynchronously, doing batch send/receive. But all these input are from the publisher and subscriber client perspective. What if the node running the Topic can not handle the huge number of transactions? How do I monitor that? How do I have the Topic running on multiple nodes? Any input on that would be helpful. Also wondering if any one has done any capacity testing with Topic/Queue and I am eager to see those results... Thanks, Prasanna

  • Retrieve a cross domain RSS(xml) through Javascript

    - by Ajay
    I have seen server side proxy workarounds for retrieving rss (xmls) from cross-domains. In fact this very question addressess my same problem but gives out a different solution. I have a constraint of do not use a proxy to retrieve rss feeds. And hence the Google AJAX Feed API solution also goes out of picture. Is there a client-only workaround for this problem. JSONP is the solution for requests that respond with JSON output. But here, I have RSS feeds which can respond with pure xml . How do I solve the problem.
