  • Implement Semi-Round-Robin file which can be expanded and saved on demand

    - by ircmaxell
    Ok, that title is going to be a little bit confusing. Let me try to explain it a little bit better. I am building a logging program. The program will have 3 main states: Write to a round-robin buffer file, keeping only the last 10 minutes of data. Write to a buffer file, ignoring the time (record all data). Rename entire buffer file, and start a new one with the past 10 minutes of data (and change state to 1). Now, the use case is this. I have been experiencing some network bottlenecks from time to time in our network. So I want to build a system to record TCP traffic when it detects the bottleneck (detection via Nagios). However by the time it detects the bottlenecking, most of the useful data has already been transmitted. So, what I'd like is to have a deamon that runs something like dumpcap all the time. In normal mode, it'll only keep the past 10 minutes of data (Since there's no point in keeping a boat load of data if it's not needed). But when Nagios alerts, I will send a signal in the deamon to store everything. Then, when Naigos recovers it will send another signal to stop storing and flush the buffer to a save file. Now, the problem is that I can't see how to cleanly store a rotating 10 minutes of data. I could store a new file every 10 minutes and delete the old ones if in mode 1. But that seems a bit dirty to me (especially when it comes to figuring out when the alert happened in the file). Ideally, the file that was saved should be such that the alert is always at the 10:00 mark in the file. While that is possible with new files every 10 minutes, it seems like a bit dirty to "repair" the files to that point. Any ideas? Should I just do a rotating file system and combine them into 1 at the end (doing quite a bit of post-processing)? Is there a way to implement the semi-round-robin file cleanly so that there is no need for any post-processing? Thanks Oh, and the language doesn't matter as much at this stage (I'm leaning towards Python, but have no objection to any other language. It's less of an issue than the overall design)...

  • Change text of UIAlertView when recording a video with UIImagePickerController and reaching the videoMaximumDuration

    - by aimak
    I'd want to know how to change to text of the UIAlertView appearing when I record a video with a UIImagePickerController and I reach the videoMaximumDuration. If it is not possible to change the text of that UIAlertView, is it at least possible to display it in another language ? Edit : the default text is "The maximum length for this video has been reached" with title "Video Recording Stopped". Thank you, aimak

  • How long does it take Google to update all links from R 301 ?

    - by romant
    I just changed the location of my blog, and have done the appropriate redirects. Does anyone have knowledge or experience for the delay in updating all the links across Google? Reason I ask, I wish to change the A record. So this will eliminate the .htaccess file, and thus null and void the redirect. How long must I wait prior to the undertaking? Thank you.

  • Why would some POST data go missing when using Uploadify?

    - by Chad Johnson
    I have been using Uploadify in my PHP application for the last couple months, and I've been trying to track down an elusive bug. I receive emails when fatal errors occur, and they provide me a good amount of details. I've received dozens of them. I have not, however, been able to reproduce the problem myself. Some users (like myself) experience no problem, while others do. Before I give details of the problem, here is the flow. User visits edit screen for a page in the CMS I am using. Record id for the page is put into a form as a hidden value. User clicks the Uploadify browse button and selects a file (only single file selection is allowed). User clicks Submit button for my form. jQuery intercepts the form submit action, triggers Uploadify to start uploading, and returns false for the submit action (manually cancelling the form submit event so that Uploadify can take over). Uploadify uploads to a custom process script. Uploadify finishes uploading and triggers the Javascript completion callback. The Javascript callback calls $('#myForm').submit() to submit the form. Now that's what SHOULD happen. I've received reports of the upload freezing at 100% and also others where "I/O Error" is displayed. What's happening is, the form is submitting with the completion callback, but some post parameters present in the form are simply not in the post data. The id for the page, which earlier I said is added to the form as a hidden field, is simply not there in the post data ($_POST)--there is no item for 'id' in the $_POST array. The strange thing is, the post data DOES contain values for some fields. For instance, I have an input of type text called "name" which is for the record name, and it does show up in the post data. Here is what I've gathered: This has been happening on Mac OSX 10.5 and 10.6, Windows XP, and Windows 7. I can post exact user agent strings if that helps. Users must use Flash 10.0.12 or later. We've made it so the form reverts to using a normal "file" field if they have < 10.0.12. Does anyone have ANY ideas at all what the cause of this could be?

  • Remove duplicates and update IDs linked to nonduplicates

    - by colinr23
    I have two tables, tableA and tableB, linked through a locationID. TableA has descriptive survey info with each record from a different time (ie unique), while TableB has purely locational information. However, there are lots of duplicates in TableB, yet each has a unique locationID, which has an entry in TableA. I've found plenty posts about removing duplicates from TableB, but how can I update the locationIDs in TableA so they are linked to the unique locations in TableB once duplicates are removed... Help much appreciated!

  • Count times ID appears in a table and return in row.

    SELECT Boats.id, Boats.date, Boats.section, Boats.raft, river_company.company, river_section.section AS river FROM Boats INNER JOIN river_company ON Boats.raft = river_company.id INNER JOIN river_section ON Boats.section = river_section.id ORDER BY Boats.date DESC, river, river_company.company Returns everything I need. But how would I add a [Photos] table and count how many times Boats.id occurs in it and add that to the returned rows. So if there are 5 photos for boat #17 I want the record for boat #17 to say PhotoCount = 5

  • Problem with PHP 'PHP_SELF'

    I am having a bit of trouble. It does not seem to be a big deal, but I have created a page that the user can edit a MySQL database. Once they click submit it should process the php within the if statement and echo 1 record updated. The problem is that it does not wait to echo the statement. It just seems to ignore the way I wrote my if and display the whole page.

  • Castle ActiveRecord - schema generation without enforcing referential integrity?

    - by Simon
    Hi all, I've just started playing with Castle active record as it seems like a gentle way into NHibernate. I really like the idea of the database schema being generate from my classes during development. I want to do something similar to the following: [ActiveRecord] public class Camera : ActiveRecordBase<Camera> { [PrimaryKey] public int CameraId {get; set;} [Property] public int CamKitId {get; set;} [Property] public string serialNo {get; set;} } [ActiveRecord] public class Tripod : ActiveRecordBase<Tripod> { [PrimaryKey] public int TripodId {get; set;} [Property] public int CamKitId {get; set;} [Property] public string serialNo {get; set;} } [ActiveRecord] public class CameraKit : ActiveRecordBase<CameraKit> { [PrimaryKey] public int CamKitId {get; set;} [Property] public string description {get; set;} [HasMany(Inverse=true, Table="Cameras", ColumnKey="CamKitId")] public IList<Camera> Cameras {get; set;} [HasMany(Inverse=true, Table="Tripods", ColumnKey="CamKitId")] public IList<Camera> Tripods {get; set;} } A camerakit should contain any number of tripods and cameras. Camera kits exist independently of cameras and tripods, but are sometimes related. The problem is, if I use createschema, this will put foreign key constraints on the Camera and Tripod tables. I don't want this, I want to be able to to set CamKitId to null on the tripod and camera tables to indicate that it is not part of a CameraKit. Is there a way to tell activerecord/nhibernate to still see it as related, without enforcing the integrity? I was thinking I could have a cameraKit record in there to indicate "no camera kit", but it seems like oeverkill. Or is my schema wrong? Am I doing something I shouldn't with an ORM? (I've not really used ORMs much) Thanks!

  • Reduce Multiple Errors logging in sysssislog

    - by Akshay
    Need help. I am trying to automate error notifications to be sent in mailers. For that I am querying the sysssislog table. I have pasted an "Execute SQl task" on the package event handler "On error". For testing purpose, I am deliberately trying to load duplicate keys in a table which consists of a Primary key column(so as to get an error). But instead of having just one error, "Violation of primary key constraint", SSIS records 3 in the table. PFA the screenshot as well. How can i restrict the tool to log only one error and not multiple ??? Package Structure. Package ("On error Event handler") - DFT - Oledb Source - Oledb Destination SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available.

Cannot insert duplicate key in object 'dbo.SalesPerson'.". SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR. The "input "OLE DB Destination Input" (56)" failed because error code 0xC020907B occurred, and the error row disposition on "input "OLE DB Destination Input" (56)" specifies failure on error. An error occurred on the specified object of the specified component. There may be error messages posted before this with more information about the failure. SSIS Error Code DTS_E_PROCESSINPUTFAILED.

The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running. There may be error messages posted before this with more information about the failure. Please guide me. Your help is very much appreciated. Thanks

  • enclosing double quotes in array

    - by Jared
    Hi all I might be looking at this the wrong way, but I have a form that does its thing (sends emails etc etc) but I also put in some code to make a simple flatfile csv log with some of the user entered details. If a user accidentally puts in for instance 'himynameis","bob' this would either break the csv row (because the quotes weren't encapsulated) or if I use htmlspecialchars() and stripslashes() on the data, I end up with a ugly data value of 'himynameis&quot;,&quot;bob'. My question is, how can I handle the incoming data to cater for '"' being put in the form without breaking my csv file? this is my code for creating the csv log file. @$name = htmlspecialchars(trim($_POST['name'])); @$emailCheck = htmlspecialchars(trim($_POST['email'])); @$title = htmlspecialchars(trim($_POST['title'])); @$phone = htmlspecialchars(trim($_POST['phone'])); function logFile($logText) { $path = 'D:\logs'; $filename = '\Log-' . date('Ym', time()) . '.csv'; $file = $path . $filename; if(!file_exists($file)) { $logHeader = array('Date', 'IP_Address', 'Title', 'Name', 'Customer_Email', 'Customer_Phone', 'file'); $fp = fopen($file, 'a'); fputcsv($fp, $line); } $fp = fopen($file, 'a'); foreach ($logText as $record) { fputcsv($fp, $record); } } //Log submission to file $date = date("Y/m/d H:i:s"); $clientIp = getIpAddress(); //get clients IP address $nameLog = stripslashes($name); $titleLog = stripslashes($title); if($_FILES['uploadedfile']['error'] == 4) $filename = "No file attached."; //check if file uploaded and return $logText = array(array("$date", "$clientIp", "$titleLog", "$nameLog", "$emailCheck", "$phone", "$filename")); logFile($logText); //write form details to log Here is a sample of the incoming array data: Array ( [0] => Array ( [0] => 2010/05/17 10:22:27 [1] => xxx.xxx.xxx.xxx [2] => title [3] => """"himynameis","bob" [4] => [email protected] [5] => 346346 [6] => No file attached. ) ) TIA Jared

  • PHP Doctrine: Custom nested set?

    - by ropstah
    Is it possible to have nested set capabilities in this somewhat custom setup? Consider these 4 tables: Object: (oid, name) contains: [1, 'Licence'] and [2, 'Exemption'] Licence: (lid, name) Exemption: (eid, name) Cost: (oid, oid_ref, cost_oid, cost_oid_ref) For: P = Licence with lid [1] R = Exemption with eid [2] i can say "object P is a parent to object R" if the following Cost record exists: [oid: 2 oid_ref: 2 cost_oid: 1 cost_oid_ref: 1] I understand that this creates somesort of 'conditional foreign key' relation which I need to define in code. Is it possible to have the nested set loaded with these conditions?

  • How to handle input and parameter validation between layers?

    - by developr
    If I have a 3 layer web forms application that takes user input, I know I can validate that input using validation controls in the presentation layer. Should I also validate in the business and data layers as well to protect against SQL injection and also issues? What validations should go in each layer? Another example would be passing a ID to return a record. Should the data layer ensure that the id is valid or should that happen in BLL / UI?
