  • User Input That Involves A ' ' Causes A Substring Out Of Range Error

    - by Greenhouse Gases
    Hi Stackoverflow people. You have already helped me quite a bit but near the end of writing this program I have somewhat of a bug. You see in order to read in city names with a space in from a text file I use a '/' that is then replaced by the program for a ' ' (and when the serializer runs the opposite happens for next time the program is run). The problem is when a user inputs a name too add, search for, or delete that contains a space, for instance 'New York' I get a Debug Assertion Error with a substring out of range expression. I have a feeling it's to do with my correctCase function, or setElementsNull that looks at the string until it experiences a null element in the array, however ' ' is not null so I'm not sure how to fix this and I'm going a bit insane. Any help would be much appreciated. Here is my code: // U08221.cpp : main project file. #include "stdafx.h" #include <_iostream> #include <_string> #include <_fstream> #include <_cmath> using namespace std; class locationNode { public: string nodeCityName;

} locationNode() // NULL constructor { } void swapProps(locationNode *node2) { locationNode place; place.nodeCityName = this->nodeCityName; place.nodeLati = this->nodeLati; place.nodeLongi = this->nodeLongi; this->nodeCityName = node2->nodeCityName; this->nodeLati = node2->nodeLati; this->nodeLongi = node2->nodeLongi; node2->nodeCityName = place.nodeCityName; node2->nodeLati = place.nodeLati; node2->nodeLongi = place.nodeLongi; } void modify(string name) { this->nodeCityName = name; } void modify(double latlon, int mod) { switch(mod) { case 2: this->nodeLati = latlon; break; case 3: this->nodeLongi = latlon; break; } } void correctCase() // Correct upper and lower case letters of input { int MAX_SIZE = 35;

  • Delphi Editbox causing unexplainable errors...

    - by NeoNMD
    On a form I have 8 edit boxes that I do the exact same thing with. They are arranged in 2 sets of 4, one is Upper and the other is Lower. I kept getting errors clearing all the edit boxes so I went through clearing them 1 by 1 and found that 1 of the edit boxes just didnt work and when I tried to run the program and change that exit box it caused the debugger to jump to a point in the code with the database (even though the edit boxes had nothing to do with the database and they arent in a procedure or stack with a database in it) and say the program has access violation there. So I then removed all mention of that edit box and the code worked perfectly again, so I deleted that edit box, copied and pasted another edit box and left all values the same, then went through my code and copied the code from the other sections and simply renamed it for the new Edit box and it STILL causes an error even though it is entirely new. I cannot figure it out so I ask you all, what the hell?

  • Clearing C#'s WebBrowser control's cookies for all sites WITHOUT clearing for IE itself

    - by Helgi Hrafn Gunnarsson
    Hail StackOverflow! The short version of what I'm trying to do is in the title. Here's the long version. I have a bit of a complex problem which I'm sure I will receive a lot of guesses as a response to. In order to keep the well-intended but unfortunately useless guesses to a minimum, let me first mention that the solution to this problem is not simple, so simple suggestions will unfortunately not help at all, even though I appreciate the effort. C#'s WebBrowser component is fundamentally IE itself so solutions with any sorts of caveats will almost certainly not work. I need to do exactly what I'm trying to do, and even a seemingly minor caveat will defeat the purpose completely. At the risk of sounding arrogant, I need assistance from someone who really has in-depth knowledge about C#'s WebBrowser and/or WinInet and/or how to communicate with Windows's underlying system from C#... or how to encapsulate C++ code in C#. That said, I don't expect anyone to do this for me, and I've found some promising hints which are explained later in this question. But first... what I'm trying to achieve is this. I have a Windows.Forms component which contains a WebBrowser control. This control needs to: Clear ALL cookies for ALL websites. Visit several websites, one after another, and record cookies and handle them correctly. This part works fine already so I don't have any problems with this. Rinse and repeat... theoretically forever. Now, here's the real problem. I need to clear all those cookies (for any and all sites), but only for the WebBrowser control itself and NOT the cookies which IE proper uses. What's fundamentally wrong with this approach is of course the fact that C#'s WebBrowser control is IE. But I'm a stubborn young man and I insist on it being possible, or else! ;) Here's where I'm stuck at the moment. It is quite simply impossible to clear all cookies for the WebBrowser control programmatically through C# alone. One must use DllImport and all the crazy stuff that comes with it. This chunk works fine for that purpose: [DllImport("wininet.dll", SetLastError = true)] private static extern bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer, int lpdwBufferLength); And then, in the function that actually does the clearing of the cookies: InternetSetOption(IntPtr.Zero, INTERNET_OPTION_END_BROWSER_SESSION, IntPtr.Zero, 0); Then all the cookies get cleared and as such, I'm happy. The program works exactly as intended, aside from the fact that it also clears IE's cookies, which must not be allowed to happen. The problem is that this also clears the cookies for IE proper, and I can't have that happen. From one fellow StackOverflower (if that's a word), Sheng Jiang proposed this to a different problem in a comment, but didn't elaborate further: "If you want to isolate your application's cookies you need to override the Cache directory registry setting via IDocHostUIHandler2::GetOverrideKeyPath" I've looked around the internet for IDocHostUIHandler2 and GetOverrideKeyPath, but I've got no idea of how to use them from C# to isolate cookies to my WebBrowser control. My experience with the Windows registry is limited to RegEdit (so I understand that it's a tree structure with different data types but that's about it... I have no in-depth knowledge of the registry's relationship with IE, for example). Here's what I dug up on MSDN: IDocHostUIHandler2 docs: http://msdn.microsoft.com/en-us/library/aa753275%28VS.85%29.aspx GetOverrideKeyPath docs: http://msdn.microsoft.com/en-us/library/aa753274%28VS.85%29.aspx I think I know roughly what these things do, I just don't know how to use them. So, I guess that's it! Any help is greatly appreciated.

  • Binding navigation property to RadGrid while using EntityDataSource control

    - by Matrix
    I'm new to Entity Framework and I got stuck in an issue while trying to bind a navigation property (foreign key reference) to a dropdownlist. I have Telerik RadGrid control which gets the data using a EntityDataSource control. Here is the model description: Applications: AppId, AppName, ServerId Servers: ServerId, ServerName The Applicaitons.ServerId is a foreign key reference to Servers.ServerId. The RadGrid lists the applications and allows the user to insert/update/delete an application. I want to show the server names as a dropdownlist in edit mode which I'm not able to. . Here is my aspx code: <telerik:RadGrid ID="gridApplications" runat="server" Skin="Sunset" AllowAutomaticInserts="True" AllowAutomaticDeletes="True" AllowPaging="True" AllowAutomaticUpdates="True" AutoGenerateColumns="False" OnItemCreated="gridApplications_ItemCreated" DataSourceID="applicationsEntityDataSource" Width="50%" OnItemInserted="gridApplications_ItemInserted" OnItemUpdated="gridApplications_ItemUpdated" OnItemDeleted="gridApplications_ItemDeleted" GridLines="None"> <MasterTableView CommandItemDisplay="Top" AutoGenerateColumns="False" DataKeyNames="AppId" DataSourceID="applicationsEntityDataSource"> <RowIndicatorColumn> <HeaderStyle Width="20px" /> </RowIndicatorColumn> <ExpandCollapseColumn> <HeaderStyle Width="20px" /> </ExpandCollapseColumn> <Columns> <telerik:GridEditCommandColumn ButtonType="ImageButton" UniqueName="EditCommandColumn" HeaderText="Edit" ItemStyle-Width="10%"> </telerik:GridEditCommandColumn> <telerik:GridButtonColumn CommandName="Delete" Text="Delete" UniqueName="DeleteColumn" ConfirmText="Are you sure you want to delete this application?" ConfirmTitle="Confirm Delete" ConfirmDialogType="Classic" ItemStyle-Width="10%" HeaderText="Delete"> </telerik:GridButtonColumn> <telerik:GridBoundColumn DataField="AppId" UniqueName="AppId" Visible="false" HeaderText="Application Id" ReadOnly="true"> </telerik:GridBoundColumn> <telerik:GridBoundColumn DataField="AppName" UniqueName="AppName" HeaderText="Application Name" MaxLength="30" ItemStyle-Width="40%"> </telerik:GridBoundColumn> <telerik:GridTemplateColumn DataField="ServerId" UniqueName="ServerId" HeaderText="Server Hosted" EditFormColumnIndex="1"> <EditItemTemplate> <asp:DropDownList ID="ddlServerHosted" runat="server" DataTextField="Servers.ServerName" DataValueField="ServerId" Width="40%"> </asp:DropDownList> </EditItemTemplate> </telerik:GridTemplateColumn> </Columns> <EditFormSettings ColumnNumber="2" CaptionDataField="AppId" InsertCaption="Insert New Application" EditFormType="AutoGenerated"> <EditColumn InsertText="Insert record" EditText="Edit application id #:" EditFormColumnIndex="0" UpdateText="Application updated" UniqueName="InsertCommandColumn1" CancelText="Cancel insert" ButtonType="ImageButton"></EditColumn> <FormTableItemStyle Wrap="false" /> <FormTableStyle GridLines="Horizontal" CellPadding="2" CellSpacing="0" Height="110px" Width="110px" /> <FormTableAlternatingItemStyle Wrap="false" /> <FormStyle Width="100%" BackColor="#EEF2EA" /> <FormTableButtonRowStyle HorizontalAlign="Right" /> </EditFormSettings> </MasterTableView> </telerik:RadGrid> <asp:EntityDataSource ID="applicationsEntityDataSource" runat="server" ConnectionString="name=AnalyticsEntities" EnableDelete="True" EntityTypeFilter="Applications" EnableInsert="True" EnableUpdate="True" EntitySetName="Applications" DefaultContainerName="AnalyticsEntities" Include="Servers"> </asp:EntityDataSource> I tried another approach where I replaced the GridTemplateColumn with the following code <telerik:RadComboBox ID="RadComboBox1" DataSourceID="serversEntityDataSource" DataTextField="ServerName" DataValueField="ServerId" AppendDataBoundItems="true" runat="server" > <Items> <telerik:RadComboBoxItem /> </Items> and using a separate EntityDataSource control as follows: <asp:EntityDataSource ID="serversEntityDataSource" runat="server" ConnectionString="name=AnalyticsEntities" EnableDelete="True" EntityTypeFilter="Servers" EnableInsert="True" EnableUpdate="True" EntitySetName="Servers" DefaultContainerName="AnalyticsEntities"> </asp:EntityDataSource> but, I get the following error. Application cannot be inserted. Reason: Entities in 'AnalyticsEntities.Applications' participate in the 'FK_Servers_Applications' relationship. 0 related 'Servers' were found. 1 'Servers' is expected. My question is, how do you bind the navigation property and load the values in the DropDownList/RadComboBox control?

  • MVC 2 with IIS 6 Problems

    - by SlackerCoder
    Hey guys, I'm using IIS 6 on a Windows 2003 Server and I am trying to get an MVC2 project installed on that machine. I am having nightmare-ish problems doing so! I've looked up TONS of references on what to do, and not 1 single one works. (They work for MVC1 projects, as I have a few of those running already using said solutions). Does anyone have any tips/hints/ideas on what needs to be done for MVC2 projects with IIS 6? I am definitely pulling my hair out over this. I have tried it on 2 of my dev servers, and both get the same result. The closest I can get to a served page is an error page "Object reference not set to an instance of an object", however, the page has try/catch blocks that are being ignored, so I dont think its running the code on the controller, I think it's saying that the controller is the error. (For the reference, the error in question is directed at the HomeController.cs file). What I've tried: Wildcard mapping Changing routes to {controller}.mvc Changing routes to {controller}.aspx Adding the .mvc extension to IIS Modifying routes in Global.asax There's a LOT of code in this project so far, so I will only post the first page(s) that should get served: MASTER PAGE: <div class="page"> <div id="header"> <div id="title"> <h1>Meritain RedCard Interface 2.0</h1> </div> <!-- This is the main menu. Each security role will have access to certain buttons. --> <div id="menucontainer"> <% if (Session["UserData"] != null) { %> <% if (/*User Security Checks Out*/) { %> <ul id="menu"> <li><%= Html.ActionLink("Home", "Index", "Home")%></li> <li><%= Html.ActionLink("Selection", "Index", "Select", new { area = "Selector" }, null)%></li> <li><%= Html.ActionLink("Audit", "Index", "Audit", new { area = "Auditor" }, null)%></li> <li><%= Html.ActionLink("Setup", "Index", "Setup", new { area = "Setup" }, null)%></li> <li><%= Html.ActionLink("About", "About", "Home")%></li> </ul> <% } %> <% } %> </div> </div> <div id="main"> <asp:ContentPlaceHolder ID="MainContent" runat="server" /> <div id="footer"> </div> </div> </div> Default.aspx.cs: [I added this file as a potential solution, since it works with MVC 1] protected void Page_Load(object sender, EventArgs e) { string originalPath = Request.Path; HttpContext.Current.RewritePath(Request.ApplicationPath, false); IHttpHandler httpHandler = new MvcHttpHandler(); httpHandler.ProcessRequest(HttpContext.Current); HttpContext.Current.RewritePath(originalPath, false); } HomeController.cs: public ActionResult Index() { loadApplication(); ViewData["Message"] = "Welcome to ASP.NET MVC!"; return View(); } public ActionResult About() { return View(); } private void loadApplication() { Session["UserData"] = CreateUserSecurity(HttpContext.User.Identity.Name.ToString()); } I did not list the CreateUserSecurity method, but all it does it call the DB using the Username and returns the record in the database that matches the username. EDIT: Added code and what I've tried so far (as requested).

  • Does Apache ever give incorrect "out of threads" errors?

    - by Eli Courtwright
    Lately our Apache web server has been giving us this error multiple times per day: [Tue Apr 06 01:07:10 2010] [error] Server ran out of threads to serve requests.

Since the Apache server runs as a separate process and the database doesn't record any problems when this error occurs, I'm doubtful that Oracle is the problem. Unfortunately, the errors are freaking out our sysadmins, who are inclined to blame any and all problems which occur with the server on this error. Is this a known bug in Apache that I simply haven't been able to find any reference to through Google?

  • MySQL Database Query Problem

    - by moustafa
    I need your help!!!. I need to query a table in my database that has record of goods sold. I want the query to detect a particular product and also calculate the quantity sold. The product are 300 now, but it would increase in the future. Below is a sample of my DB Table #---------------------------- # Table structure for litorder #---------------------------- CREATE TABLE `litorder` ( `id` int(10) NOT NULL auto_increment, `name` varchar(50) NOT NULL default '', `address` varchar(50) NOT NULL default '', `xdate` date NOT NULL default '0000-00-00', `ref` varchar(20) NOT NULL default '', `code1` varchar(50) NOT NULL default '', `code2` varchar(50) NOT NULL default '', `code3` varchar(50) NOT NULL default '', `code4` varchar(50) NOT NULL default '', `code5` varchar(50) NOT NULL default '', `code6` varchar(50) NOT NULL default '', `code7` varchar(50) NOT NULL default '', `code8` varchar(50) NOT NULL default '', `code9` varchar(50) NOT NULL default '', `code10` varchar(50) NOT NULL default '', `code11` varchar(50) character set latin1 collate latin1_bin NOT NULL default '', `code12` varchar(50) NOT NULL default '', `code13` varchar(50) NOT NULL default '', `code14` varchar(50) NOT NULL default '', `code15` varchar(50) NOT NULL default '', `product1` varchar(100) NOT NULL default '0', `product2` varchar(100) NOT NULL default '0', `product3` varchar(100) NOT NULL default '0', `product4` varchar(100) NOT NULL default '0', `product5` varchar(100) NOT NULL default '0', `product6` varchar(100) NOT NULL default '0', `product7` varchar(100) NOT NULL default '0', `product8` varchar(100) NOT NULL default '0', `product9` varchar(100) NOT NULL default '0', `product10` varchar(100) NOT NULL default '0', `product11` varchar(100) NOT NULL default '0', `product12` varchar(100) NOT NULL default '0', `product13` varchar(100) NOT NULL default '0', `product14` varchar(100) NOT NULL default '0', `product15` varchar(100) NOT NULL default '0', `price1` int(10) NOT NULL default '0', `price2` int(10) NOT NULL default '0', `price3` int(10) NOT NULL default '0', `price4` int(10) NOT NULL default '0', `price5` int(10) NOT NULL default '0', `price6` int(10) NOT NULL default '0', `price7` int(10) NOT NULL default '0', `price8` int(10) NOT NULL default '0', `price9` int(10) NOT NULL default '0', `price10` int(10) NOT NULL default '0', `price11` int(10) NOT NULL default '0', `price12` int(10) NOT NULL default '0', `price13` int(10) NOT NULL default '0', `price14` int(10) NOT NULL default '0', `price15` int(10) NOT NULL default '0', `quantity1` int(10) NOT NULL default '0', `quantity2` int(10) NOT NULL default '0', `quantity3` int(10) NOT NULL default '0', `quantity4` int(10) NOT NULL default '0', `quantity5` int(10) NOT NULL default '0', `quantity6` int(10) NOT NULL default '0', `quantity7` int(10) NOT NULL default '0', `quantity8` int(10) NOT NULL default '0', `quantity9` int(10) NOT NULL default '0', `quantity10` int(10) NOT NULL default '0', `quantity11` int(10) NOT NULL default '0', `quantity12` int(10) NOT NULL default '0', `quantity13` int(10) NOT NULL default '0', `quantity14` int(10) NOT NULL default '0', `quantity15` int(10) NOT NULL default '0', `amount1` int(10) NOT NULL default '0', `amount2` int(10) NOT NULL default '0', `amount3` int(10) NOT NULL default '0', `amount4` int(10) NOT NULL default '0', `amount5` int(10) NOT NULL default '0', `amount6` int(10) NOT NULL default '0', `amount7` int(10) NOT NULL default '0', `amount8` int(10) NOT NULL default '0', `amount9` int(10) NOT NULL default '0', `amount10` int(10) NOT NULL default '0', `amount11` int(10) NOT NULL default '0', `amount12` int(10) NOT NULL default '0', `amount13` int(10) NOT NULL default '0', `amount14` int(10) NOT NULL default '0', `amount15` int(10) NOT NULL default '0', `totalNaira` double(20,0) NOT NULL default '0', `totalDollar` int(20) NOT NULL default '0', PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='InnoDB free: 4096 kB;

  • Cisco PIX 8.0.4, static address mapping not working?

    - by Bill
    upgrading a working Pix running 5.3.1 to 8.0.4. The memory/IOS upgrade went fine, but the 8.0.4 configuration is not quite working 100%. The 5.3.1 config on which it was based is working fine. Basically, I have three networks (inside, outside, dmz) with some addresses on the dmz statically mapped to outside addresses. The problem seems to be that those addresses can't send or receive traffic from the outside (Internet.) Stuff on the DMZ that does not have a static mapping seems to work fine. So, basically: Inside - outside: works Inside - DMZ: works DMZ - inside: works, where the rules allow it DMZ (non-static) - outside: works But: DMZ (static) - outside: fails Outside - DMZ: fails (So, say, udp 1194 traffic to .102, http to .104) I suspect there's something I'm missing with the nat/global section of the config, but can't for the life of me figure out what. Help, anyone? The complete configuration is below. Thanks for any thoughts! !

  • Creating a GraphicsPath from a semi-transparent bitmap

    - by Moozhe
    I want to create a GraphicsPath and a list of Points to form the outline of the non-transparent area of a bitmap. If needed, I can guarantee that each image has only one solid collection of nontransparent pixels. So for example, I should be able to record the points either clockwise or counter-clockwise along the edge of the pixels and perform a full closed loop. The speed of this algorithm is not important. However, the efficiency of the resulting points is semi-important if I can skip some points to reduce in a smaller and less complex GraphicsPath. I will list my current code below which works perfectly with most images. However, some images which are more complex end up with paths which seem to connect in the wrong order. I think I know why this occurs, but I can't come up with a solution. public static Point[] GetOutlinePoints(Bitmap image) { List<Point> outlinePoints = new List<Point>(); BitmapData bitmapData = image.LockBits(new Rectangle(0, 0, image.Width, image.Height), ImageLockMode.ReadOnly, PixelFormat.Format32bppArgb); byte[] originalBytes = new byte[image.Width * image.Height * 4]; Marshal.Copy(bitmapData.Scan0, originalBytes, 0, originalBytes.Length); for (int x = 0; x < bitmapData.Width; x++) { for (int y = 0; y < bitmapData.Height; y++) { byte alpha = originalBytes[y * bitmapData.Stride + 4 * x + 3]; if (alpha != 0) { Point p = new Point(x, y); if (!ContainsPoint(outlinePoints, p)) outlinePoints.Add(p); break; } } } for (int y = 0; y < bitmapData.Height; y++) { for (int x = bitmapData.Width - 1; x >= 0; x--) { byte alpha = originalBytes[y * bitmapData.Stride + 4 * x + 3]; if (alpha != 0) { Point p = new Point(x, y); if (!ContainsPoint(outlinePoints, p)) outlinePoints.Add(p); break; } } } for (int x = bitmapData.Width - 1; x >= 0; x--) { for (int y = bitmapData.Height - 1; y >= 0; y--) { byte alpha = originalBytes[y * bitmapData.Stride + 4 * x + 3]; if (alpha != 0) { Point p = new Point(x, y); if (!ContainsPoint(outlinePoints, p)) outlinePoints.Add(p); break; } } } for (int y = bitmapData.Height - 1; y >= 0; y--) { for (int x = 0; x < bitmapData.Width; x++) { byte alpha = originalBytes[y * bitmapData.Stride + 4 * x + 3]; if (alpha != 0) { Point p = new Point(x, y); if (!ContainsPoint(outlinePoints, p)) outlinePoints.Add(p); break; } } } // Added to close the loop outlinePoints.Add(outlinePoints[0]); image.UnlockBits(bitmapData); return outlinePoints.ToArray(); } public static bool ContainsPoint(IEnumerable<Point> points, Point value) { foreach (Point p in points) { if (p == value) return true; } return false; } And when I turn the points into a path: GraphicsPath outlinePath = new GraphicsPath(); outlinePath.AddLines(_outlinePoints); Here's an example showing what I want. The red outline should be an array of points which can be made into a GraphicsPath in order to perform hit detection, draw an outline pen, and fill it with a brush.

  • C# asp.net EF MVC postgresql error 23505: Duplicate key violates unique constraint

    - by user2721755
    EDIT: It was issue with database table - dropping and recreating table id column did the work. Problem solved. I'm trying to build web application, that is connected to postgresql database. Results are displaying in view with Kendo UI. When I'm trying to add new row (with Kendo UI 'Add new record' button), I get error 23505: 'Duplicate key violates unique constraint'. My guess is, that EF takes id to insert from the beginning, not the last one, because after 35 (it's number of rows in table) tries - and errors - adding works perfectly. Can someone help me to understand, what's wrong?

  • Intermittent Connection Issues to SQL Server 2008 R2 RTM

    - by Chandan Jha
    The problem I am facing is a very complex one and inspite of trying to gather a root cause of the problem, I am standing at the same place after 2 months with just bits and pieces of information.Here is a scenario: There is a windows 2003 server which uses an system DSN ODBC connection. I looked into the driver properties and it is as follows: Name Version File SQL Server 2000.86.3959.00 SQLSRV32.DLL Now, this system DSN has been given configured with TCP\IP in Network Libraries and 'determine port dynamically' is checked. Now, lets come to the database destination. It is hosted on Windows 2008 having SQL 2008 R2 RTM version 64-bit. Now, I will give you a an overview about the events that happen and whatever troubleshooting I could perform: I get an email saying 'blah blah' failed and the only message their application gets is 'cannot connect to database' I go the SQL Server logs and find the following information: Login failed for user ''. Reason: An attempt to login using SQL authentication failed. Server is configured for Windows authentication only. [CLIENT: 10.0.0.xx Error: 18456, Severity: 14, State: 58.] A quick search shows that this error may come when an SQL Server is configured with windows authentication but its not true. We have mixed mode and connection issue is intermittent. This SQL Server is configured to run on a local system account but since we use only SQL Server accounts to connect to this, there should not be any Kerberos errors. When I run a profiler trace and see only 'existing connections', i see a lot of them coming from my client server displaying the sql user but NO hostname is shown. Textdata field shows TCP\IP information along with some arithabort and ansi-null settings. Now, I tried looking into ring connectivity buffer by using following: SELECTCAST(record AS XML) FROM sys.dm_os_ring_buffers WHERE ring_buffer_type = 'RING_BUFFER_CONNECTIVITY' One sample output is: <ConnectivityTraceRecord> <RecordType>Error</RecordType> <RecordSource>Tds</RecordSource> <Spid>118</Spid> <SniConnectionId>5124905D-D1EC-460E-AD78-201050B78C67</SniConnectionId> <OSError>0</OSError> <SniConsumerError>18452</SniConsumerError> <SniProvider>7</SniProvider> <State>1</State> <RemoteHost>10.0.0.21</RemoteHost> <RemotePort>5008</RemotePort> <LocalHost>10.1.0.38</LocalHost> <LocalPort>1433</LocalPort> <RecordTime>6/6/2012 21:14:57.527</RecordTime> <TdsBuffersInformation> <TdsInputBufferError>0</TdsInputBufferError> <TdsOutputBufferError>0</TdsOutputBufferError> <TdsInputBufferBytes>120</TdsInputBufferBytes> </TdsBuffersInformation> <TdsDisconnectFlags> <PhysicalConnectionIsKilled>0</PhysicalConnectionIsKilled> <DisconnectDueToReadError>0</DisconnectDueToReadError> <NetworkErrorFoundInInputStream>0</NetworkErrorFoundInInputStream> <ErrorFoundBeforeLogin>0</ErrorFoundBeforeLogin> <SessionIsKilled>0</SessionIsKilled> <NormalDisconnect>0</NormalDisconnect> </TdsDisconnectFlags> </ConnectivityTraceRecord> <Stack> <frame id="0">0X000000000174C34B</frame> <frame id="1">0X0000000001748FDD</frame> <frame id="2">0X0000000002461001</frame> <frame id="3">0X0000000000C47E98</frame> <frame id="4">0X00000000008015AD</frame> <frame id="5">0X0000000000801492</frame> <frame id="6">0X00000000003CBBD8</frame> <frame id="7">0X00000000003CB8BA</frame> <frame id="8">0X00000000003CB6FF</frame> <frame id="9">0X00000000008E8FB6</frame> <frame id="10">0X00000000008E9175</frame> <frame id="11">0X00000000008E9839</frame> <frame id="12">0X00000000008E9502</frame> <frame id="13">0X0000000074E437D7</frame> <frame id="14">0X0000000074E43894</frame> <frame id="15">0X00000000775A652D</frame> Somehow all the errors show error number 18452 whereas I never found this error in my SQL logs where I see only 18456. I am just stuck on a dead end because this connection issue appears intermittently. Sorry for a long question but I hope if you read this, you can make out that I tried a lot at my end before giving up.

  • Mac OS X Server Open Directory does not push Software Update settings to clients

    - by joxl
    I have an Xserve G5 running Mac OS X Server 10.5.8 configured as an Open Directory master. I have also enabled and configured Software Update service on the machine. The SUS is configured to serve Tiger, Leopard and Snow Leopard clients (see http://discussions.apple.com/message.jspa?messageID=10297359#10297359) The clients bound to the OD are a variety of Mac's running OS X 10.4, 10.5 or 10.6. In Workgroup Manager, I have created 3 machine groups for each client OS. Each group is configured with a custom SUS URL, and the managed client computers are members accordingly (see http://discussions.apple.com/thread.jspa?messageID=10493154#10493154) My problem is that the server pushes the SUS settings to some of the client machines, but not all. When I first configured all this stuff on the server (a few weeks ago) I was closely monitoring a few of the client machines to confirm that they received the custom settings. I noticed that some of the clients (10.4/5/6 alike) seemed to get the settings immediately, others didn't show the new settings until after a reboot. As I said, results are mixed across OS's, but some clients will not "sync" at all. My immediate thought was to unbind/rebind the problematic machines. I did this on several client computers with no success. For example, today I was working on one of the Tiger clients. I noticed it was not pointed at my local SUS, so I checked the OD binding; it was fine. Just to be sure I unbound the machine. Next, I checked WM and confirmed the computer record was gone. I noticed the machine group still had a residual (broken?) member from the unbound client; I manually removed this. Finally, I re-bound the client to OD and re-added the machine to it's correct group in WM. Unfortunately, the client still pings apple's SUS for updates. Just to play it safe I rebooted the client, but to no avail, it will not see my local SUS. To confirm that there is nothing wrong with the server, or the client's connection to it, forcefully pointed the machine at my SUS: sudo defaults write /Library/Preferences/com.apple.SoftwareUpdate CatalogURL "$LOCAL_SUS_URL" and the machine successfully updated off my local server. Great, successful updates, but problem not solved. I've done exhaustive reading on discussions.apple.com (not saying I read everything, I'm just saying I have read a lot) without a good answer. The discouraging thing is that a lot of OD problems I've read about only result in the sysadmin completely reinstalling the server, or OD, or some other similarly heavy-handed operation. At this point, I am not willing to go that route. I still have hope that I can find the reason for this flaky behavior. If anyone can point me in a helpful direction it would be much appreciated. EDIT: Indeed, some files are being pushed to the client: # from client machine: $ sudo find /Library -type f -name com.apple.SoftwareUpdate.plist /Library/Managed Preferences/com.apple.SoftwareUpdate.plist /Library/Managed Preferences/username/com.apple.SoftwareUpdate.plist /Library/Preferences/com.apple.SoftwareUpdate.plist A few weeks ago, prior to my (previously mentioned) modifications, the SUS was still running "stock". Which meant it could not serve SL (10.6) machines. At that time, the Software Update settings were setup in WM under User Groups. This didn't make any sense because some users work on multiple machines with different OS's. Before creating Machine Groups in WM, I deleted all the SU settings from the User Group Preferences. This just makes the whole thing more confusing, because when I see a file here: /Library/Managed Preferences/username/com.apple.SoftwareUpdate.plist I assume it's still remaining from the "old" settings, because I wouldn't think a Machine Setting belongs there. Despite all the com.apple.SoftwareUpdate.plist hanging around under the Managed Preferences, why does the client machine still call home to Apple and not my SUS? # on client machine: $ date Tue Jan 25 17:01:46 EST 2011 $ softwareupdate --list Software Update Tool Copyright 2002-2005 Apple No new software available. switch terminals... # on server: $ tail -n1 /var/log/swupd/swupd_access_log 10.x.x.x - - [25/Jan/2011:15:54:29 -0500] XXXX POST "/cgi-bin/SoftwareUpdateServerStats" 200 13 ... Notice the date of the client softwareupdate and the latest access to the SUS server; the server never heard a peep from that client.

  • Where to Store the Protection Trial Info for Software Protection Purpose

    - by Peter Lee
    It might be duplicate with other questions, but I swear that I googled a lot and search at StackOverflow.com a lot, and I cannot find the answer to my question: In a C#.Net application, where to store the protection trial info, such as Expiration Date, Number of Used Times? I understand that, all kinds of Software Protection strategies can be cracked by a sophiscated hacker (because they can almost always get around the expiration checking step). But what I'm now going to do is just to protect it in a reasonable manner that a "common"/"advanced" user cannot screw it up. OK, in order to proof that I have googled and searched a lot at StackOverflow.com, I'm listing all the possible strategies I got: 1. Registry Entry First, some users might not have the access to even read the Registry table. Second, if we put the Protection Trial Info in a Registry Entry, the user can always find it out where it is by comparing the differences before and after the software installation. They can just simply change it. OK, you might say that we should encrypt the Protection Trial Info, yes we can do that. But what if the user just change their system date before installing? OK, you might say that we should also put a last-used date, if something is wrong, the last-used date could work as a protection guide. But what if the user just uninstall the software and delete all Registry Entries related to this software, and then reinstall the software? I have no idea on how to deal with this. Please help. A Plain File First, there are some places to put the plain file: 2.a) a simple XML file under software installation path 2.b) configuration file Again, the user can just uninstall the software and remove these plain file(s), and reinstall the software. - The Software Itself If we put the protection trial info (Expiration Date, we cannot put Number of Used Times) in the software itself, it is still susceptible to the cases I mentioned above. Furthermore, it's not even cool to do so. - A Trial Product-Key It works like a licensing process, that is, we put the Trial info into an RSA-signed string. However, it requires too many steps for a user to have a try of using the software (they might lose patience): 4.a) The user downloads the software; 4.b) The user sends an email to request a Trial Product-Key by providing user name (or email) or hardware info; 4.c) The server receives the request, RSA-signs it and send back to the user; 4.d) The user can now use it under the condition of (Expiration Date & Number of Used Times). Now, the server has a record of the user's username or hardware info, so the user will be rejected to request a second trial. Is it legal to collection hardware info? In a word, the user has to do one more extra step (request a Trial Product Key) just for having a try of using the software, which is not cool (thinking myself as a user). NOTE: This question is not about the Licensing, instead, it's about where to store the TRIAL info. After the trial expires, the user should ask for a license (CD-Key/Product-Key). I'm going to use RSA signature (bound to User Hardware)

  • Preloading Winforms using a Stack and Hidden Form

    - by msarchet
    I am currently working on a project where we have a couple very control heavy user controls that are being used inside a MDI Controller. This is a Line of Business app and it is very data driven. The problem that we were facing was the aforementioned controls would load very very slowly, we dipped our toes into the waters of multi-threading for the control loading but that was not a solution for a plethora of reasons. Our solution to increasing the performance of the controls ended up being to 'pre-load' the forms onto a hidden window, create a stack of the existing forms, and pop off of the stack as the user requested a form. Now the current issue that I'm seeing that will arise as we push this 'fix' out to our testers, and the ultimately our users is this: Currently the 'hidden' window that contains the preloaded forms is visible in task manager, and can be shut down thus causing all of the controls to be lost. Then you have to create them on the fly losing the performance increase. Secondly, when the user uses up the stack we lose the performance increase (current solution to this is discussed below). For the first problem, is there a way to hide this window from task manager, perhaps by creating a parent form that encapsulates both the main form for the program and the hidden form? Our current solution to the second problem is to have an inactivity timer that when it fires checks the stacks for the forms, and loads a new form onto the stack if it isn't full. However this still has the potential of causing a hang in the UI while it creates the forms. A possible solutions for this would be to put 'used' forms back onto the stack, but I feel like there may be a better way. EDIT: For control design clarification From the comments I have realized there is a lack of clarity on what exactly the control is doing. Here is a detailed explanation of one of the controls. I have defined for this control loading time as the time it takes from when a user performs an action that would open a control, until the time a control is accessible to be edited. The control is for entering Prescriptions for a patient in the system, it has about 5 tabbed groups with a total of about 180 controls. The user selects to open a new Prescription control from inside the main program, this control is loaded into the MDI Child area of the Main Form (which is a DevExpress Ribbon Control). From the time the user clicks New (or loads an existing record) until the control is visible. The list of actions that happens in the program is this: The stack is checked for the existence of a control. If the control exists it is popped off of the stack. The control is rendered on screen. This is what takes 2 seconds The control then is populated with a blank object, or with existing data. The control is ready to use. The average percentage of loading time, across about 10 different machines, with different hardware the control rendering takes about 85 - 95 percent of the control loading time. Without using the stack the control takes about 2 seconds to load, with the stack it takes about .8 seconds, this second time is acceptable. I have looked at Henry's link and I had previously already implemented the applicable suggestions. Again I re-iterate my question as What is the best method to move controls to and from the stack with as little UI interruption as possible?

  • With Eclipselink/JPA, can I have a Foreign Composite Key that shares a field with a Primary Composit

    - by user107924
    My database has two entities; Company and Person. A Company can have many People, but a Person must have only one Company. The table structure looks as follows. COMPANY ---------- owner PK comp_id PK c_name PERSON ---------------- owner PK, FK1 personid PK comp_id FK1 p_fname p_sname It has occurred to me that I could remove PERSON.OWNER and derive it through the foreign key; however, I can't make this change without affecting legacy code. I have modeled these as JPA-annotated classes; @Entity @Table(name = "PERSON") @IdClass(PersonPK.class) public class Person implements Serializable { @Id private String owner; @Id private String personid; @ManyToOne @JoinColumns( {@JoinColumn(name = "owner", referencedColumnName = "OWNER", insertable = false, updatable = false), @JoinColumn(name = "comp_id", referencedColumnName = "COMP_ID", insertable = true, updatable = true)}) private Company company; private String p_fname; private String p_sname; ...and standard getters/setters... } @Entity @Table(name = "COMPANY") @IdClass(CompanyPK.class) public class Company implements Serializable { @Id private String owner; @Id private String comp_id; private String c_name; @OneToMany(mappedBy = "company", cascade=CascadeType.ALL) private List people; ...and standard getters/setters... } My PersonPK and CompanyPK classes are nothing special, they just serve as a struct holding owner and the ID field, and override hashCode and equals(o). So far so good. I come across a problem, however, when trying to deal with associations. It seems if I have an existing Company, and create a Person, and associate to the Person to the Company and persist the company, the association is not saved when the Person is inserted. For example, my main code looks like this: EntityManager em = emf.createEntityManager(); em.getTransaction().begin(); CompanyPK companyPK = new CompanyPK(); companyPK.owner="USA"; companyPK.comp_id="1102F3"; Company company = em.find(Company.class, companyPK); Person person = new Person(); person.setOwner("USA"); person.setPersonid("5116628123"); //some number that doesn't exist yet person.setP_fname("Hannah"); person.setP_sname("Montana"); person.setCompany(company); em.persist(person); This completes without error; however in the database I find that the Person record was inserted with a null in the COMP_ID field. With EclipseLink debug logging set to FINE, the SQL query is shown as: INSERT INTO PERSON (PERSONID,OWNER,P_SNAME,P_FNAME) VALUES (?,?,?,?) bind = [5116628123,USA,Montana,Hannah,] I would have expected this to be saved, and the query to be equivalent to INSERT INTO PERSON (PERSONID,OWNER,COMP_ID,P_SNAME,P_FNAME) VALUES (?,?,?,?,?) bind = [5116628123,USA,1102F3,Montana,Hannah,] What gives? Is it incorrect to say updatable/insertable=true for one half of a composite key and =false for the other half? If I have updatable/insertable=true for both parts of the foreign key, then Eclipselink fails to startup saying that I can not use the column twice without having one set to readonly by specifying these options.

  • SOAP call with query on result (SSRS, Sharepoint)

    - by Erik404
    Hi! I created a report in VS using a shared data source which is connected to a sharepoint list. In the report I created a dataset with a SOAP call to the data source so I get the result from the sharepoint list in a table. this is the soap call <Query> <SoapAction>http://schemas.microsoft.com/sharepoint/soap/GetListItems</SoapAction> <Method Namespace="http://schemas.microsoft.com/sharepoint/soap/" Name="GetListItems"> <Parameters> <Parameter Name="listName"> <DefaultValue>{BD8D39B7-FA0B-491D-AC6F-EC9B0978E0CE}</DefaultValue> </Parameter> <Parameter Name="viewName"> <DefaultValue>{E2168426-804F-4836-9BE4-DC5F8D08A54F}</DefaultValue> </Parameter> <Parameter Name="rowLimit"> <DefaultValue>9999</DefaultValue> </Parameter> </Parameters> </Method> <ElementPath IgnoreNamespaces="True">*</ElementPath> </Query> THis works fine, I have a result which I can show in a report, but I want to have the ability to select a parameter to filter the result on. I have created a parameter and when I preview the Report I see the dropdownbox which I can use to make a selection from the Title field, when I do this it still shows the first record, obviously it doens't work yet (DUH!) because I need to create a query somewhere, But! I have no idea where, I tried to include <Where> <Eq> <FieldRef Name="ows_Title" /> <Value Type="Text">testValue</Value> </Eq> </Where> in the the soap request but it didn't worked... I've searched teh intarwebz but couldn't find any simliar problems... kinda stuck now...any thoughts on this? EDIT Here's the query I used according to the blogpost Alex Angas linked. <Query> <SoapAction>http://schemas.microsoft.com/sharepoint/soap/GetListItems</SoapAction> <Method Namespace="http://schemas.microsoft.com/sharepoint/soap/" Name="GetListItems"> <queryOptions></queryOptions> <query><Query> <Where> <Eq> <FieldRef Name="ows_Title"/> <Value Type="Text">someValue</Value> </Eq> </Where> </Query></query> <Parameters> <Parameter Name="listName"> <DefaultValue>{BD8D39B7-FA0B-491D-AC6F-EC9B0978E0CE}</DefaultValue> </Parameter> <Parameter Name="viewName"> <DefaultValue>{E2168426-804F-4836-9BE4-DC5F8D08A54F}</DefaultValue> </Parameter> <Parameter Name="rowLimit"> <DefaultValue>9999</DefaultValue> </Parameter> </Parameters> </Method> <ElementPath IgnoreNamespaces="True">*</ElementPath> </Query> I tried to put the new query statement in every possible way in the existing, but it doesn't work at all, I do not get an error though so the code is valid, but I still get an unfiltered list as return... pulling my hair out here!

  • How to overcome shortcomings in reporting from EAV database?

    - by David Archer
    The major shortcomings with Entity-Attribute-Value database designs in SQL all seem to be related to being able to query and report on the data efficiently and quickly. Most of the information I read on the subject warn against implementing EAV due to these problems and the commonality of querying/reporting for almost all applications. I am currently designing a system where almost all the fields necessary for data storage are not known at design/compile time and are defined by the end-user of the system. EAV seems like a good fit for this requirement but due to the problems I've read about, I am hesitant in implementing it as there are also some pretty heavy reporting requirements for this system as well. I think I've come up with a way around this but would like to pose the question to the SO community. Given that typical normalized database (OLTP) still isn't always the best option for running reports, a good practice seems to be having a "reporting" database (OLAP) where the data from the normalized database is copied to, indexed extensively, and possibly denormalized for easier querying. Could the same idea be used to work around the shortcomings of an EAV design? The main downside I see are the increased complexity of transferring the data from the EAV database to reporting as you may end up having to alter the tables in the reporting database as new fields are defined in the EAV database. But that is hardly impossible and seems to be an acceptable tradeoff for the increased flexibility given by the EAV design. This downside also exists if I use a non-SQL data store (i.e. CouchDB or similar) for the main data storage since all the standard reporting tools are expecting a SQL backend to query against. Do the issues with EAV systems mostly go away if you have a seperate reporting database for querying? EDIT: Thanks for the comments so far. One of the important things about the system I'm working on it that I'm really only talking about using EAV for one of the entities, not everything in the system. The whole gist of the system is to be able to pull data from multiple disparate sources that are not known ahead of time and crunch the data to come up with some "best known" data about a particular entity. So every "field" I'm dealing with is multi-valued and I'm also required to track history for each. The normalized design for this ends up being 1 table per field which makes querying it kind of painful anyway. Here are the table schemas and sample data I'm looking at (obviously changed from what I'm working on but I think it illustrates the point well): EAV Tables Person ------------------- - Id - Name - ------------------- - 123 - Joe Smith - ------------------- Person_Value ------------------------------------------------------------------- - PersonId - Source - Field - Value - EffectiveDate - ------------------------------------------------------------------- - 123 - CIA - HomeAddress - 123 Cherry Ln - 2010-03-26 - - 123 - DMV - HomeAddress - 561 Stoney Rd - 2010-02-15 - - 123 - FBI - HomeAddress - 676 Lancas Dr - 2010-03-01 - ------------------------------------------------------------------- Reporting Table Person_Denormalized ---------------------------------------------------------------------------------------- - Id - Name - HomeAddress - HomeAddress_Confidence - HomeAddress_EffectiveDate - ---------------------------------------------------------------------------------------- - 123 - Joe Smith - 123 Cherry Ln - 0.713 - 2010-03-26 - ---------------------------------------------------------------------------------------- Normalized Design Person ------------------- - Id - Name - ------------------- - 123 - Joe Smith - ------------------- Person_HomeAddress ------------------------------------------------------ - PersonId - Source - Value - Effective Date - ------------------------------------------------------ - 123 - CIA - 123 Cherry Ln - 2010-03-26 - - 123 - DMV - 561 Stoney Rd - 2010-02-15 - - 123 - FBI - 676 Lancas Dr - 2010-03-01 - ------------------------------------------------------ The "Confidence" field here is generated using logic that cannot be expressed easily (if at all) using SQL so my most common operation besides inserting new values will be pulling ALL data about a person for all fields so I can generate the record for the reporting table. This is actually easier in the EAV model as I can do a single query. In the normalized design, I end up having to do 1 query per field to avoid a massive cartesian product from joining them all together.

  • Fluent NHibernate Many to one mapping

    - by Jit
    I am new to Hibernate world. It may be a silly question, but I am not able to solve it. I am testing many to One relationship of tables and trying to insert record. I have a Department table and Employee table. Employee and Dept has many to One relationship here. I am using Fluent NHibernate to add records. All codes below. Pls help - SQL Code create table Dept ( Id int primary key identity, DeptName varchar(20), DeptLocation varchar(20)) create table Employee ( Id int primary key identity, EmpName varchar(20),EmpAge int, DeptId int references Dept(Id)) Class Files public partial class Dept { public virtual System.String DeptLocation { get; set; } public virtual System.String DeptName { get; set; } public virtual System.Int32 Id { get; private set; } public virtual IList<Employee> Employees { get; set; } } public partial class Employee { public virtual System.Int32 DeptId { get; set; } public virtual System.Int32 EmpAge { get; set; } public virtual System.String EmpName { get; set; } public virtual System.Int32 Id { get; private set; } public virtual Project.Model.Dept Dept { get; set; } } Mapping Files public class DeptMapping : ClassMap { public DeptMapping() { Id(x = x.Id); Map(x = x.DeptName); Map(x = x.DeptLocation); HasMany(x = x.Employees) .Inverse() .Cascade.All(); } } public class EmployeeMapping : ClassMap { public EmployeeMapping() { Id(x = x.Id); Map(x = x.EmpName); Map(x = x.EmpAge); Map(x = x.DeptId); References(x = x.Dept) .Cascade.None(); } } My Code to add try { Dept dept = new Dept(); dept.DeptLocation = "Austin"; dept.DeptName = "Store"; Employee emp = new Employee(); emp.EmpName = "Ron"; emp.EmpAge = 30; IList<Employee> empList = new List<Employee>(); empList.Add(emp); dept.Employees = empList; emp.Dept = dept; IRepository<Dept> rDept = new Repository<Dept>(); rDept.SaveOrUpdate(dept); } catch (Exception ex) { Console.WriteLine(ex.Message); } Here i am getting error as InnerException = {"Invalid column name 'Dept_id'."} Message = "could not insert: [Project.Model.Employee][SQL: INSERT INTO [Employee] (EmpName, EmpAge, DeptId, Dept_id) VALUES (?, ?, ?, ?); select SCOPE_IDENTITY()]"

  • Python: Improving long cumulative sum

    - by Bo102010
    I have a program that operates on a large set of experimental data. The data is stored as a list of objects that are instances of a class with the following attributes: time_point - the time of the sample cluster - the name of the cluster of nodes from which the sample was taken code - the name of the node from which the sample was taken qty1 = the value of the sample for the first quantity qty2 = the value of the sample for the second quantity I need to derive some values from the data set, grouped in three ways - once for the sample as a whole, once for each cluster of nodes, and once for each node. The values I need to derive depend on the (time sorted) cumulative sums of qty1 and qty2: the maximum value of the element-wise sum of the cumulative sums of qty1 and qty2, the time point at which that maximum value occurred, and the values of qty1 and qty2 at that time point. I came up with the following solution: dataset.sort(key=operator.attrgetter('time_point')) # For the whole set sys_qty1 = 0 sys_qty2 = 0 sys_combo = 0 sys_max = 0 # For the cluster grouping cluster_qty1 = defaultdict(int) cluster_qty2 = defaultdict(int) cluster_combo = defaultdict(int) cluster_max = defaultdict(int) cluster_peak = defaultdict(int) # For the node grouping node_qty1 = defaultdict(int) node_qty2 = defaultdict(int) node_combo = defaultdict(int) node_max = defaultdict(int) node_peak = defaultdict(int) for t in dataset: # For the whole system ###################################################### sys_qty1 += t.qty1 sys_qty2 += t.qty2 sys_combo = sys_qty1 + sys_qty2 if sys_combo > sys_max: sys_max = sys_combo # The Peak class is to record the time point and the cumulative quantities system_peak = Peak(time_point=t.time_point, qty1=sys_qty1, qty2=sys_qty2) # For the cluster grouping ################################################## cluster_qty1[t.cluster] += t.qty1 cluster_qty2[t.cluster] += t.qty2 cluster_combo[t.cluster] = cluster_qty1[t.cluster] + cluster_qty2[t.cluster] if cluster_combo[t.cluster] > cluster_max[t.cluster]: cluster_max[t.cluster] = cluster_combo[t.cluster] cluster_peak[t.cluster] = Peak(time_point=t.time_point, qty1=cluster_qty1[t.cluster], qty2=cluster_qty2[t.cluster]) # For the node grouping ##################################################### node_qty1[t.node] += t.qty1 node_qty2[t.node] += t.qty2 node_combo[t.node] = node_qty1[t.node] + node_qty2[t.node] if node_combo[t.node] > node_max[t.node]: node_max[t.node] = node_combo[t.node] node_peak[t.node] = Peak(time_point=t.time_point, qty1=node_qty1[t.node], qty2=node_qty2[t.node]) This produces the correct output, but I'm wondering if it can be made more readable/Pythonic, and/or faster/more scalable. The above is attractive in that it only loops through the (large) dataset once, but unattractive in that I've essentially copied/pasted three copies of the same algorithm. To avoid the copy/paste issues of the above, I tried this also: def find_peaks(level, dataset): def grouping(object, attr_name): if attr_name == 'system': return attr_name else: return object.__dict__[attrname] cuml_qty1 = defaultdict(int) cuml_qty2 = defaultdict(int) cuml_combo = defaultdict(int) level_max = defaultdict(int) level_peak = defaultdict(int) for t in dataset: cuml_qty1[grouping(t, level)] += t.qty1 cuml_qty2[grouping(t, level)] += t.qty2 cuml_combo[grouping(t, level)] = (cuml_qty1[grouping(t, level)] + cuml_qty2[grouping(t, level)]) if cuml_combo[grouping(t, level)] > level_max[grouping(t, level)]: level_max[grouping(t, level)] = cuml_combo[grouping(t, level)] level_peak[grouping(t, level)] = Peak(time_point=t.time_point, qty1=node_qty1[grouping(t, level)], qty2=node_qty2[grouping(t, level)]) return level_peak system_peak = find_peaks('system', dataset) cluster_peak = find_peaks('cluster', dataset) node_peak = find_peaks('node', dataset) For the (non-grouped) system-level calculations, I also came up with this, which is pretty: dataset.sort(key=operator.attrgetter('time_point')) def cuml_sum(seq): rseq = [] t = 0 for i in seq: t += i rseq.append(t) return rseq time_get = operator.attrgetter('time_point') q1_get = operator.attrgetter('qty1') q2_get = operator.attrgetter('qty2') timeline = [time_get(t) for t in dataset] cuml_qty1 = cuml_sum([q1_get(t) for t in dataset]) cuml_qty2 = cuml_sum([q2_get(t) for t in dataset]) cuml_combo = [q1 + q2 for q1, q2 in zip(cuml_qty1, cuml_qty2)] combo_max = max(cuml_combo) time_max = timeline.index(combo_max) q1_at_max = cuml_qty1.index(time_max) q2_at_max = cuml_qty2.index(time_max) However, despite this version's cool use of list comprehensions and zip(), it loops through the dataset three times just for the system-level calculations, and I can't think of a good way to do the cluster-level and node-level calaculations without doing something slow like: timeline = defaultdict(int) cuml_qty1 = defaultdict(int) #...etc. for c in cluster_list: timeline[c] = [time_get(t) for t in dataset if t.cluster == c] cuml_qty1[c] = [q1_get(t) for t in dataset if t.cluster == c] #...etc. Does anyone here at Stack Overflow have suggestions for improvements? The first snippet above runs well for my initial dataset (on the order of a million records), but later datasets will have more records and clusters/nodes, so scalability is a concern. This is my first non-trivial use of Python, and I want to make sure I'm taking proper advantage of the language (this is replacing a very convoluted set of SQL queries, and earlier versions of the Python version were essentially very ineffecient straight transalations of what that did). I don't normally do much programming, so I may be missing something elementary. Many thanks!

  • Confirm disk is broken when it passes all diagnostics

    - by Halfgaar
    I have a system with a potentially broken disk, but the disk passes all manner of diagnostics. I have been unable to confirm that the disk is broken. What are my options? I could just replace the disk, but because this situation is very similar to another more severe situation I have (long story), I'd like to actually make a proper diagnosis as opposed to randomly binning hardware. The issue and history is this: I had a Debian Linux PC (500 MHz P3) acting as router, nagios and munin. It crashed every couple of weeks. No logs or dmesg could be obtained (because it's an old Compaq that only boots when you configure it as keyboardless, making connecting a keyboard later, once it's booted, impossible). At the time, I just replaced the computer with another Compaq (P4 2.4 GHz) because I thought the hardware was faulty. However, it still crashed every couple of weeks. the difference is that on this computer, I can still SSH into it. It gives all kinds of errors on hda. I'd like to confirm that the disk is broken, but nothing I do confirms this: SMART error logs shows no errors. Normally when a disk starts acting up, SMART my pass, but it still records a read-error in the error log. SMART self-test (smartctl -t long /dev/sda) completes without errors. re-allocated sector count (a tell-tale parameter) has been 31 all its life, even when the disk was still in use in my desktop PC years ago, and it still is. The figure never changed. dd if=/dev/sda of=/dev/null bs=4096 passes with flying colors. What else can I do to assess the health of the drive? Again, this is not about making this router fully functional again, this is a disk forensic question, because it just so happens that I have another server that potentially has the same problem, and knowing the answer to this will possibly help me greatly. For the record, below are logs and such. This is the smartctl -a output: smartctl 5.40 2010-07-12 r3124 [i686-pc-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Model Family: Seagate Barracuda 7200.7 and 7200.7 Plus family Device Model: ST3120026A Serial Number: 5JT1CLQM Firmware Version: 3.06 User Capacity: 120,034,123,776 bytes Device is: In smartctl database [for details use: -P show] ATA Version is: 6 ATA Standard is: ATA/ATAPI-6 T13 1410D revision 2 Local Time is: Mon Jul 1 21:18:33 2013 CEST SMART support is: Available - device has SMART capability.
