  • MongoDB initialization error in Rails

    - by rube_noob
    I have an initialization script to set up my MongoDB connection in the config/initialization directory. It is my understanding that these initializers run after all of the plugins are initialized. The problem I am having is that when a particular plugin I am using is initialized, it tries to access the mongodb before I have set it up. I get this error: uninitialized class variable @@database_name in MongoMapper My question is: Where can I initialize Mongodb that will run after the mongodb gem has been loaded and before any of the plugins are initialized?

  • Why does ANT tell me that JAVA_HOME is wrong when it is not?

    - by Ankur
    I get the error: C:\dev\ws\springapp\build.xml:81: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK. It is currently set to "C:\Program Files\Java\jre6" But I have clearly set my JAVA_HOME to be C:\Program Files\Java\jdk1.6.0_14 Where is ANT getting this value?

  • NSArrayController binding : Suppress "No selection"

    - by Holli
    Hello, I have a texfield bound to an ArrayController. The controller key is "selection" because I select items from a NSTableView. But when there are no items in the table the textfield shows the gray text "no selection". How can I suppress this text and have just an empty textfield? Or how can I change the "No selection" text to something else?

  • Multiple Connection Types for one Designer Generated TableAdapter

    - by Tim
    I have a Windows Forms application with a DataSet (.xsd) that is currently set to connect to a Sql Ce database. Compact Edition is being used so the users can use this application in the field without an internet connection, and then sync their data at day's end. I have been given a new project to create a supplemental web interface for displaying some of the same reports as the Windows Forms application so certain users can obtain reports without installing the Windows app. What I've done so far is create a new Web Project and added it to my current Solution. I have split both the reports (.rdlc) and DataSets out of the Windows Forms project into their own projects so they can be accessed by both the Windows and Web applications. So far, this is working fine. Here's my dilemma: As I said before, the DataSets are currently set up to connect to a local Sql Ce database file. This is correct for the Windows app, but for the Web application I would like to use these same TableAdapters and queries to connect to the Sql Server 2005 database. I have found that the designer generated, strongly-typed TableAdapter classes have a ConnectionModifier property that allows you to make the TableAdapter's Connection public. This exposes the Connection property and allows me to set it, however it is strongly-typed as a SqlCeConnection, whereas I would like to set it to a SqlConnection for my Web project. I'm assuming the DataSet Designer strongly-types the Connection, Command, and DataAdapter objects based on the Provider of the ConnectionString as indicated in the app.config file. Is there any way I can use some generic provider so that the DataSet Designer will use object types that can connect to both a Sql Ce database file AND the actual Sql Server 2005 database? I know that SqlCeConnection and SqlConnection both inherit from DbConnection, which implements IDbConnection. Relatively, the same goes for SqlCeCommand/SqlCommand:DbCommand:IDbCommand. It would be nice if I could just figure out a way for the designer to use the Interface types rather than the strong types, but I'm hesitant that that is possible. I hope my problem and question are clear. Any help is much appreciated. Let me know if there's anything I can clarify.

  • PHP max_execution_time not timing out

    - by Joey Ezekiel
    This is not one of the regular questions if sleep is counted for timeout or stuff like that. Ok, here's the problem: I've set the max_execution_time for PHP as 15 seconds and ideally this should time out when it crosses the set limit, but it doesn't. Apache has been restarted after the change to the php.ini file and an ini_get('max_execution_time') is all fine. Sometimes the script runs for upto 200 seconds which is crazy. I have no database communication whatsoever. All the script does is looking for files on the unix filesystem and in some cases re-directing to another JSP page. There is no sleep() on the script. I calculate the total execution time of the PHP script like this: At the start of the script I set : $_mtime = microtime(); $_mtime = explode(" ",$_mtime); $_mtime = $_mtime[1] + $_mtime[0]; $_gStartTime = $_mtime; and the end time($_gEndTime) is calculated similarly. The total time is calculated in a shutdown function that I've registered: register_shutdown_function('shutdown'); ............. function shutdown() { .............. .............. $_total_time = $_gEndTime - $_gStartTime; .............. switch (connection_status ()) { case CONNECTION_NORMAL: .... break; .... case CONNECTION_TIMEOUT: .... break; ...... } } Note: I cannot use $_SERVER['REQUEST_TIME'] because my PHP version is incompatible. That sucks - I know. 1) Well, my first question obviously is is why is my PHP script executing even after the set timeout limit? 2) Apache has the Timeout directive which is 300 seconds but the PHP binary does not read the Apache config and this should not be a problem. 3) Is there a possibility that something is sending PHP into a sleep mode? 4) Am I calculating the execution time in a wrong way? Is there a better way to do this? I'm stumped at this point. PHP Wizards - please help.

  • Why does "request.getUserPrincipal().getName()" sometimes return a blank string?

    - by Marcus
    Has somebody an idea, why the getName method of the requests getUserPrincipal Method sometimes provides an empty String? Most of the time it returns the correct user name but not every time. This behaviour does occur randonmly. I can start the application, run the command and it works. The next time I start the application and run the command (exactly the same way as before!) it does not work... Any ideas?

  • Problem to generate nested ul lists using PHP

    - by Michael Mao
    Hi all: I am working on a front-end web app where a nested unordered list would be used for the jQuery plugin mcdropdown. Here is the data structure from PHP: a nested array of arrays : Array ( [0] => Array ( [fullpath] => ../foil/alphanumeric/ [depth] => 0 ) [1] => Array ( [fullpath] => ../foil/alphanumeric/letters/ [depth] => 1 ) [2] => Array ( [fullpath] => ../foil/alphanumeric/numbers/ [depth] => 1 ) [3] => Array ( [fullpath] => ../foil/alphanumeric/numbers/symbols/ [depth] => 2 ) ) Basically, I took the excellent answer from this question on SO, modified it a bit : global $fullpaths; // $fullpaths contains the above data structure in print_r $result = ''; $currentDepth = -1; while(!empty($fullpaths)) { $currentNode = array_shift($fullpaths); if($currentNode['depth'] > $currentDepth) { $result .='<ul>'; } if($currentNode['depth'] < $currentDepth) { $result .=str_repeat('</ul>', $currentDepth - $currentNode['depth']); } $result .= '<li>'. $currentNode['fullpath'] .'</li>'; $currentDepth = $currentNode['depth']; if(empty($fullpaths)) { $result .= str_repeat('</ul>', 1 + $currentDepth); } } print $result; and got the following output: <ul> <li>../foil/alphanumeric/</li> <ul> <li>../foil/alphanumeric/letters/</li> <li>../foil/alphanumeric/numbers/</li> <ul> <li>../foil/alphanumeric/numbers/symbols/</li> </ul> </ul> </ul> Which cannot be accepted by the mcdropdown jQuery plugin, it expects something like this: <li rel="1"> 'Alphanumeric' <ul> <li rel="2">'Letters'</li> <li rel="3">'Numbers' <ul> <li rel="4">'Symbols'</li> </ul> </li> </ul> </li> To be frank, I don't quite understand how the answer from that question works, I have been trying to modify that solution to cope with my situation, but still failed. Any help and suggestion is much appropriated in advance.

  • Does mprotect flush the instruction cache on ARM Linux?

    - by Adam Goode
    I am writing a JIT on ARM Linux that executes an instruction set that contains self-modifying code. The instruction set does not have any cache flush instructions (similar to x86 in that respect). If I write out some code to a page and then call mprotect on that page, is that sufficient to invalidate the instruction cache? Or do I also need to use the cacheflush syscall on those pages?

    - by corgrath
    3 questions: 1) What is the difference between connection and read timeout for sockets? 2) What does connection timeout set to "infinity" mean? In what situation can it remain in an infinitive loop? and what can trigger that the infinity-loop dies? 3) What does read timeout set to "infinity" mean? In what situation can it remain in an infinitive loop? and what can trigger that the infinity-loop dies?

  • Cannot Access Shared Folder From IIS

    - by Tim Scott
    From IIS I need to access a folder on another computer. Both servers are Window 2008 SP2, and they live in a Virtual Private Cloud on Amazon EC2. They reach one another by private IP -- they are in WORKGROUP, not a domain. I can access the shared folder manually when logged in to the client as Administrator. But IIS gets "access denied." Here's what I have done: Set File Sharing = ON Set Password Protected Sharing = OFF Set Public Folder Sharing = ON Shared the folder Added permission to the share: Everyone, Full Control Added permission to the share: NETWORK SERVICE, Full Control Verified that File & Printer Sharing is checked in Windows Firewall Opened port 445 to inbound traffic from local sources I tried adding <remote-machine-name>\NETWORK SERVICE to the share but it says it does not recognize the machine, which makes sense, I guess. As I said, from the other computer I have no trouble accessing the shared folder from my user account, but IIS is shut out. How does the file server even know the difference? I would assume that with Everyone given full control and password protected sharing turned off, it would not matter what the client user account is. In any case, how to solve? UPDATE: To clarify, I am not trying to serve up files on the share directly through IIS. Rather I am writing files to the share from my code (System.IO).

  • Parallels Plesk returning strange numbers

    - by Jack W-H
    Hi everyone, As a relatively new Server Admin I've become a bit confused by some statistics Parallels Plesk Panel 10.0.1 is returning to me. I have a domain ('subscription') set up, mysite.com. Mysite.com only hosts files, mostly images Its file contents use up about 390MB of disk space Here's a screenshot: this is what Plesk is reporting mysite.com to use: And some more info: Now this is pretty confusing... I thought at first my site might have been hacked and had contents written to disk, but I checked and all is in order, nothing has been hacked into as far as I can tell. So I had a look in the site's CP for some more in-depth statistics, and this is what's returned... Now - sod's law - when I go to check my disk space statistics in more depth via the control panel, this morning it says "The data were not collected yet." - not too sure what that means, but, last night when I checked it was reporting something odd. It said Files were using up 390MB, but 1.80GB or so were being used up by 'Mail Accounts'. This is really strange, as there are no mail accounts set up for the domain. The only hint of 'mail' there is, is the catchall set up to forward *@mysite.com to a separate, ISP-hosted email account. Any ideas anybody? I can post more details if you need it. Sorry to be a bit vague but I'm not sure what else I can post. Thanks, Jack
