  • Issue with mysql backup in cron

    - by Aaron
    I'm just trying to perform a mysqldump and have it scheduled. I'm using RHEL 5 and have added it to the crontab as shown below: 22 13 * * * root mysqldump --user=root --password=12345 mysqldb /var/backups/mysqldbdate +%d%m.sql The .sql file never ended up in the backups folder. I even attempted to run this command line and it worked fine which tells me its something to do with the cron. Furthermore, I added a simple comand like "ls" and the output to the same directory and it worked fine. Any ideas? Thanks, Aaron

  • Precise explanation of JavaScript <-> DOM circular reference issue

    - by Joey Adams
    One of the touted advantages of jQuery.data versus raw expando properties (arbitrary attributes you can assign to DOM nodes) is that jQuery.data is "safe from circular references and therefore free from memory leaks". An article from Google titled "Optimizing JavaScript code" goes into more detail: The most common memory leaks for web applications involve circular references between the JavaScript script engine and the browsers' C++ objects' implementing the DOM (e.g. between the JavaScript script engine and Internet Explorer's COM infrastructure, or between the JavaScript engine and Firefox XPCOM infrastructure). It lists two examples of circular reference patterns: DOM element → event handler → closure scope → DOM DOM element → via expando → intermediary object → DOM element However, if a reference cycle between a DOM node and a JavaScript object produces a memory leak, doesn't this mean that any non-trivial event handler (e.g. onclick) will produce such a leak? I don't see how it's even possible for an event handler to avoid a reference cycle, because the way I see it: The DOM element references the event handler. The event handler references the DOM (either directly or indirectly). In any case, it's almost impossible to avoid referencing window in any interesting event handler, short of writing a setInterval loop that reads actions from a global queue. Can someone provide a precise explanation of the JavaScript ↔ DOM circular reference problem? Things I'd like clarified: What browsers are effected? A comment in the jQuery source specifically mentions IE6-7, but the Google article suggests Firefox is also affected. Are expando properties and event handlers somehow different concerning memory leaks? Or are both of these code snippets susceptible to the same kind of memory leak? // Create an expando that references to its own element. var elem = document.getElementById('foo'); elem.myself = elem; // Create an event handler that references its own element. var elem = document.getElementById('foo'); elem.onclick = function() { elem.style.display = 'none'; }; If a page leaks memory due to a circular reference, does the leak persist until the entire browser application is closed, or is the memory freed when the window/tab is closed?

  • SQL Duplicates Issue SQL SERVER 2000

    - by jeff
    I have two tables : Product and ProductRateDetail. The parent table is Product. I have duplicate records in the product table which need to be unique. There are entries in the ProductRateDetail table which correspond to duplicate records in the product table. Somehow I need to update the ProductRateDetail table to match the original (older) ID from the Product table and then remove the duplicates from the product table. I would do this manually but there are 100's of records. i.e. something like UPDATE tbl_productRateDetail SET productID = (originalID from tbl_product) then something like DELETE from tbl_product WHERE duplicate ID and only delete the recently added ID data example: (sorry can't work out this formatting thing) tbl_Product select * from dbo.Product where ProductCode = '10003' ProductID ProductTypeID ProductDescription ProductCode ProductSize 365 1 BEND DOUBLE FLANGED 10003 80mmX90deg 1354 1 BEND DOUBLE FLANGED 10003 80mmX90deg tbl_ProductRateDetail SELECT * FROM [MSTS2].[dbo].[ProductRateDetail] WHERE ProductID in (365,1354) ProductRateDetailID ProductRateID ProductID UnitRate 365 1 365 16.87 1032 5 365 16.87 2187 10 365 16.87 2689 11 365 16.87 3191 12 365 16.87 7354 21 1354 21.30 7917 22 1354 21.30 8480 23 1354 21.30 9328 25 1354 21.30 9890 26 1354 21.30 10452 27 1354 21.30 Please help!

  • Silverlight WinDg Memory Release Issue

    - by Chris Newton
    Hi, I have used WinDbg succesfully on a number of occasions to track down and fix memory leaks (or more accurately the CLRs inability to garbage collect a released object), but am stuck with one particular control. The control is displayed within a child window and when the window is closed a reference to the control remains and cannot be garbage collected. I have resolved what I believe to be the majority of the issues that could have caused the leak, but the !gcroot of the affected object is not clear (to me at least) as to what is still holding on to this object. The ouput is always the same regardless of the content being presented in the child window: DOMAIN(03FB7238):HANDLE(Pinned):79b12f8:Root: 06704260(System.Object[])- 05719f00(System.Collections.Generic.Dictionary2[[System.IntPtr, mscorlib],[System.Object, mscorlib]])-> 067c1310(System.Collections.Generic.Dictionary2+Entry[[System.IntPtr, mscorlib],[System.Object, mscorlib]][])- 064d42b0(System.Windows.Controls.Grid)- 064d4314(System.Collections.Generic.Dictionary2[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]])-> 064d4360(System.Collections.Generic.Dictionary2+Entry[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]][])- 064d3860(System.Windows.Controls.Border)- 064d4218(System.Collections.Generic.Dictionary2[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]])-> 064d4264(System.Collections.Generic.Dictionary2+Entry[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]][])- 064d3bfc(System.Windows.Controls.ContentPresenter)- 064d3d64(System.Collections.Generic.Dictionary2[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]])-> 064d3db0(System.Collections.Generic.Dictionary2+Entry[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]][])- 064d3dec(System.Collections.Generic.Dictionary2[[System.UInt32, mscorlib],[System.Windows.DependencyObject, System.Windows]])-> 064d3e38(System.Collections.Generic.Dictionary2+Entry[[System.UInt32, mscorlib],[System.Windows.DependencyObject, System.Windows]][])- 06490b04(Insurer.Analytics.SharedResources.Controls.HistoricalKPIViewerControl) If anyone has any ideas about what could potentially be the problem, or if you require more information, please let me know.

  • PHP file upload issue

    - by Varun
    I am working on a PHP based, ticket management system. While creating a ticket, one can upload an attachment. I want to put a limit (say 10 MB) per file upload. To implement this I plan the following- 1. In php.ini set post_max_size = 10M 2.In PHP script which receives the POST- Since the file is larger than post_max_size, $_FILES[] will be empty. But I can still check the content-length header and discard the upload, if size more than 10M. While testing this I tried uploading a file of 1 GB and analysed the http traffic and this is what I found. - the entire 1 GB data is first uploaded to a to the server temporarily and discarded once the http request completes. Though I couldn't exactly find out where the file was getting saved(as it was not there in the temporary directory in the server.), but my http traffic analyzer showed that the browser did send 1 GB data to the server. - the PHP script execution started only after completion of the http request(i.e after uploading the entire 1 GB) Now I have 2 concerns: a) People may exploit my server bandwidth by trying to upload large file, which I will have to discard anyways. b) Even worse, if someone starts uploading a huge file (say 100 GB), entire 100 GB data is first uploaded to the server temporarily, that means for that period, it will consume that much of memory on my server. What's the common solution for this. Am I missing something here?

  • Can't mass-assign protected attributes -- unsolved issue

    I have read about 10 different posts here about this problem, and I have tried every single one and the error will not go away.

  • Multiple dispatching issue

    - by user1440263
    I try to be synthetic: I'm dispatching an event from a MovieClip (customized symbol in library) this way: public function _onMouseDown(e:MouseEvent){ var obj = {targetClips:["tondo"],functionString:"testFF"}; dispatchEvent(new BridgeEvent(BridgeEvent.BRIDGE_DATA,obj)); } The BridgeEvent class is the following: package events { import flash.events.EventDispatcher; import flash.events.Event; public class BridgeEvent extends Event { public static const BRIDGE_DATA:String = "BridgeData"; public var data:*; public function BridgeEvent(type:String, data:*) { this.data = data; super(type, true); } } } The document class listens to the event this way: addEventListener(BridgeEvent.BRIDGE_DATA,eventSwitcher); In eventSwitcher method I have a simple trace("received"). What happens: when I click the MovieClip the trace action gets duplicated and the output window writes many "received" (even if the click is only one). What happens? How do I prevent this behaviour? What is causing this? Any help is appreciated. [SOLVED] I'm sorry, you will not believe this. A colleague, to make me a joke, converted the MOUSE_DOWN handler to MOUSE_OVER.

  • FileSearch strictness issue

    - by JakeTheSnake
    I'm currently trying to search directories for any file labelled "??.??.????.xls" (for mm.dd.yyyy.xls). The problem I have is that the code I'm using also matches filenames such as "my-restaurant.12.01.2006.xls". I only want to match filenames with specifically the notation I used above. Dim Invoices As FileSearch Set Invoices = Application.FileSearch With Invoices .Filename = "??.??.????.xls" ' invDir is a directory I chose earlier on .LookIn = invDir .SearchSubFolders = True .MatchTextExactly = True End With Is there something I'm missing? I know I could do yet another check in my code elsewhere to make sure the filename's length is 14 characters, but is there a parameter I'm not considering in the FileSearch?

  • Asp.net Date Binding Issue with Nulls

    - by Matthew Kruskamp
    I have a nullable date in my database. I am connecting to it with a LinqDataSource, and binding with a FormView. It allows you to place dates fine, but if you remove the date I need it to insert the null value to the db. It is instead throwing an exception. <asp:TextBox ID="TxtStartDate" runat="server" Text='<%# Bind("StartDate", "{0:MM/dd/yyyy}") %>' /> Works fine if you place a date in it, but if you delete the date out of it and save, you get System.Data.SqlTypes.SqlTypeException: SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM. How do I make it send null?

  • Issue about Tomcat 5.5 "ROOT" directory.

    - by Captain Kidd
    Now I specify a directory name for "appBase" attribute on "{TomcatHome}/config/server.xml". <host appBase="d:/aaa"> <Context docBase="d:/aaa/bbb"> </Context> </host> When I navigate URL to "http://localhost:8080", TOMCAT think "d:/aaa/ROOT" as application directory. I want to know how can I modify this mechanism to make TOMCAT auto search my specified directory. For example: When I input "http://localhost:8080", TOMCAT would search "d:/aaa/{SpecifiedDirectoryName}/"

  • Firebug profiling issue: "no activity to profile"

    - by thermal7
    I want to try some different options with some javascript (jQuery) to see which is the fastest, however I can't get profiling working properly. Here is the code I want to test. $this.keypress(function(e) { console.profile("test"); //retrieve the charcode if possible, otherwise get the keycode k = e.which ? e.which : e.CharCode; if (blockKeyCodes.indexOf("|" + k + "|") != -1 || e.ctrlKey && k == 86) e.preventDefault(); console.profileEnd(); }); However, when I run this the console states "no activity to profile". If I use console.time the result is 0ms. Anyone know how to fix this?

  • Intermittent Issue Writing to Google Appengine Datastore

    - by user242153
    Hi, I have a functioning app and recently have had intermittent problems writing to the datastore. I did not make any relevant code changes, however in the last few days my attempts to write to the datastore sometimes work and sometimes don't. I am trying to save an object that is in a many to one relationship with an existing persisted parent. So, the logic works like this: 1) Parent pulled from the datastore 2) Child created / instantiated using constructor 3) Parent.addSingleChild(child); // the "addSingleChild" method just adds the object argument to the collection of children 4) child.setParent(Parent); // sets the Parent object to the parent field I am using transactions as explained in the documentation ending with "finally {if (tx.isActive()) {tx.rollback(); } }" When the servlet is called, the parent is called from the datastore and the child object is created and added to the many to one mapping to the pre-existing parent. The child should automatically be persisted, since the parent is already persistent, and the child is added to the collection of children that map to the parent. And it worked this way in the past. However, to be sure, i did add a pm.makePersistent(child). Doesn't seem to help, still have the intermittent problem. Any suggestions would be appreciated, and if you need to see the actual code I can post. Thanks
