  • oci_connect Blank Page in PHP

    - by Bryan
    UPDATE (3/8/2010) I installed Xdebug and have it tracing my code. This is the output I am getting: TRACE START [2010-03-08 17:53:05] 0.2090 327864 -> {main}() /data/aims3/http/octest.php:0 0.2091 327988 -> ini_set(string(14), string(1)) /data/aims3/http/octest.php:3 0.2093 327920 -> error_reporting(long) /data/aims3/http/octest.php:4 0.2094 328048 -> oci_connect(string(8), string(8), string(25)) /data/aims3/http/octest.php:6 The trace halts at that point. I have installed everything the same way on a local server and it works fine. To say I am at a complete loss would be putting it lightly. *NOTE: I ran make test and it returned FAIL on every test. I never ran this on my working machine to see if it reports the same errors. Any idea why make test would report FAIL but make doesn't report any error? I've installed the Oracle Instantclient with no reported errors along with the OCI8 PECL package and at a loss. Whenever I try to open a connection with oci_connect, it halts my entire PHP script. EXAMPLE: <?php ini_set ("display_errors", "1"); error_reporting(E_ALL); echo "before"; $conn = oci_connect("username", "password", "host"); echo "after"; ?> Returns a complete blank page. The module is loaded (seen in phpinfo) and everything installed with no errors. I am at a complete loss. CentOS: 5.4 Apache: 2.2.3 PHP: 5.3.1 InstantClient: 11.2 oci8: 1.4.1 Any thoughts? NOTES Apache Error Log reports nothing Attempted Debugging: 1: <?php ini_set ("display_errors", "1"); error_reporting(E_ALL); echo "before"; if(!function_exists('oci_connect')) die('Oracle Not Installed'); echo "after"; ?> Returns: beforeafter 2: Changing host to //host Returns: Same error

  • Cancel UITouch Events When View Covered By Modal UIViewController

    - by kkrizka
    Hi there, I am writing an application where the user has to move some stuff on the screen using his fingers and drop them. To do this, I am using the touchesBegan,touchesEnded... function of each view that has to be moved. The problem is that sometimes the views are covered by a view displayed using the [UIViewController presentModalViewController] function. As soon as that happens, the UIView that I was moving stops receiving the touch events, since it was covered up. But there is no event telling me that it stopped receiving the events, so I can reset the state of the moved view. The following is an example that demonstrates this. The functions are part of a UIView that is being shown in the main window. It listens to touch events and when I drag the finger for some distance, it presents a modal view that covers everything. In the Run Log, it prints what touch events are received. - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"touchesBegan"); touchStart=[[touches anyObject] locationInView:self]; } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { CGPoint touchAt=[[touches anyObject] locationInView:self]; float xx=(touchAt.x-touchStart.x)*(touchAt.x-touchStart.x); float yy=(touchAt.y-touchStart.y)*(touchAt.y-touchStart.y); float rr=xx+yy; NSLog(@"touchesMoved %f",rr); if(rr > 100) { NSLog(@"Show modal"); [viewController presentModalViewController:[UIViewController new] animated:NO]; } } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"touchesEnded"); } - (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"touchesCancelled"); } But when I test the application and trigger the modal dialog to be displayed, the following is the output in the Run Log. [Session started at 2010-03-27 16:17:14 -0700.] 2010-03-27 16:17:18.831 modelTouchCancel[2594:207] touchesBegan 2010-03-27 16:17:19.485 modelTouchCancel[2594:207] touchesMoved 2.000000 2010-03-27 16:17:19.504 modelTouchCancel[2594:207] touchesMoved 4.000000 2010-03-27 16:17:19.523 modelTouchCancel[2594:207] touchesMoved 16.000000 2010-03-27 16:17:19.538 modelTouchCancel[2594:207] touchesMoved 26.000000 2010-03-27 16:17:19.596 modelTouchCancel[2594:207] touchesMoved 68.000000 2010-03-27 16:17:19.624 modelTouchCancel[2594:207] touchesMoved 85.000000 2010-03-27 16:17:19.640 modelTouchCancel[2594:207] touchesMoved 125.000000 2010-03-27 16:17:19.641 modelTouchCancel[2594:207] Show modal Any suggestions on how to reset the state of a UIView when its touch events are interrupted by a modal view?

  • OpenCV 2.4.2 on Matlab 2012b (Windows 7)

    - by Maik Xhani
    Hello i am trying to use OpenCV 2.4.2 in Matlab 2012b. I have tried those actions: downloaded OpenCV 2.4.2 used CMake on opencv folder using Visual Studio 10 and Visual Studio 10 Win64 compiler built Debug and Release version with Visual Studio first without any other option and then with D_SCL_SECURE=1 specified for every project changed Matlab's mexopts.bat and adding new lines refering to library and include (see bottom for mexopts.bat content) with Visual Studio 10 compiler tried to compile a simple file with a OpenCV library inclusion and all goes well. try to compile something that actually uses OpenCV commands and get errors. I used openmexopencv library and when tried to compile something i get this error cv.make mex -largeArrayDims -D_SECURE_SCL=1 -Iinclude -I"C:\OpenCV\build\include" -L"C:\OpenCV\build\x64\vc10\lib" -lopencv_calib3d242 -lopencv_contrib242 -lopencv_core242 -lopencv_features2d242 -lopencv_flann242 -lopencv_gpu242 -lopencv_haartraining_engine -lopencv_highgui242 -lopencv_imgproc242 -lopencv_legacy242 -lopencv_ml242 -lopencv_nonfree242 -lopencv_objdetect242 -lopencv_photo242 -lopencv_stitching242 -lopencv_ts242 -lopencv_video242 -lopencv_videostab242 src+cv\CamShift.cpp lib\MxArray.obj -output +cv\CamShift CamShift.cpp C:\Program Files\MATLAB\R2012b\extern\include\tmwtypes.h(821) : warning C4091: 'typedef ': ignorato a sinistra di 'wchar_t' quando non si dichiara alcuna variabile c:\program files\matlab\r2012b\extern\include\matrix.h(319) : error C4430: identificatore di tipo mancante, verr… utilizzato int.

  • Const operator overloading problems in C++

    - by steigers
    Hello everybody, I'm having trouble with overloading operator() with a const version: #include <iostream> #include <vector> using namespace std; class Matrix { public: Matrix(int m, int n) { vector<double> tmp(m, 0.0); data.resize(n, tmp); } ~Matrix() { } const double & operator()(int ii, int jj) const { cout << " - const-version was called - "; return data[ii][jj]; } double & operator()(int ii, int jj) { cout << " - NONconst-version was called - "; if (ii!=1) { throw "Error: you may only alter the first row of the matrix."; } return data[ii][jj]; } protected: vector< vector<double> > data; }; int main() { try { Matrix A(10,10); A(1,1) = 8.8; cout << "A(1,1)=" << A(1,1) << endl; cout << "A(2,2)=" << A(2,2) << endl; double tmp = A(3,3); } catch (const char* c) { cout << c << endl; } } This gives me the following output: NONconst-version was called - - NONconst-version was called - A(1,1)=8.8 NONconst-version was called - Error: you may only alter the first row of the matrix. How can I achieve that C++ call the const-version of operator()? I am using GCC 4.4.0. Thanks for your help! Sebastian

  • dojo/dijit ContentPane setting content

    - by Kitson
    I am trying append some XML retrieved via a dojo.XHRGet to a dijit.layout.ContentPane. Everything works ok in Firefox (3.6) but in Chrome, I only get back 'undefined' in the particular ContentPane. My code looks something like this: var cp = dijit.byId("mapDetailsPane"); cp.destroyDescendants(); // there are some existing Widgets/content I want to clear // and replace with the new content var xhrData = { url : "getsomexml.php", handleAs: "xml", preventCache: true, failOk: true }; var deferred = new dojo.xhrGet(xhrData); deferred.addCallback(function(data) { console.log(data.firstChild); // get a DOM object in both Firebug // and Chrome Dev Tools cp.attr("content",data.firstChild); // get the XML appended to the doc in Firefox, // but "undefined" in Chrome }); Because in both browsers I get back a valid Document object I know XHRGet is working fine, but there seems to be some sort of difference in how the content is being set. Is there a better way to handle the return data from the request? There was a request to see my XML, so here is part of it... <?xml version="1.0" encoding="UTF-8" standalone="no"?> <svg xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" width="672" height="1674"> <defs> <style type="text/css"> <![CDATA[ ...bunch of CSS... ]]> </style> <marker refX="0" refY="0" orient="auto" id="A00End" style="overflow: visible;"> ...bunch more defs... </defs> <g id="endpoints"> ...bunch of SVG with a some... <a xlink:href="javascript:gotoLogLine(16423,55);" xlink:type="simple">...more svg...</a> </g> </svg> I have run the output XML trough the WC3 validator for XML to verify it is valid. Like I said before, works in FireFox 3.6. I tried it on Safari and I got the same "undefined" so it seems to be related to Webkit.

  • directshow Renderstream fails with grayscale bitmaps

    - by Roey
    Hi all. I'm trying to create a directshow graph to playback a video composed of 8bit grayscale bitmaps. (using directshow.net.) I'm using a source filter and the vmr9 renderer. The source filter's output pin is defined using the following code : bmi.Size = Marshal.SizeOf(typeof(BitmapInfoHeader)); bmi.Width = width; bmi.Height = height;; bmi.Planes = 1; bmi.BitCount = (short)bitcount; bmi.Compression = 0; bmi.ImageSize = Math.Abs(bmi.Height) * bmi.Width * bmi.BitCount / 8; bmi.ClrUsed = bmi.BitCount <= 8 ? 256 : 0; bmi.ClrImportant = 0; //bmi.XPelsPerMeter = 0; //bmi.YPelsPerMeter = 0; bool isGrayScale = bmi.BitCount <= 8 ? true : false; int formatSize = Marshal.SizeOf(typeof(BitmapInfoHeader)); if (isGrayScale == true) { MessageWriter.Log.WriteTrace("Playback is grayscale."); /// Color table holds an array of 256 RGBQAD values /// Those are relevant only for grayscale bitmaps formatSize += Marshal.SizeOf(typeof(RGBQUAD)) * bmi.ClrUsed; } IntPtr ptr = Marshal.AllocHGlobal(formatSize); Marshal.StructureToPtr(bmi, ptr, false); if (isGrayScale == true) { /// Adjust the pointer to the beginning of the /// ColorTable address and create the grayscale color table IntPtr ptrNext = (IntPtr)((int)ptr + Marshal.SizeOf(typeof(BitmapInfoHeader))); for (int i = 0; i < bmi.ClrUsed; i++) { RGBQUAD rgbCell = new RGBQUAD(); rgbCell.rgbBlue = rgbCell.rgbGreen = rgbCell.rgbRed = (byte)i; rgbCell.rgbReserved = 0; Marshal.StructureToPtr(rgbCell, ptrNext, false); ptrNext = (IntPtr)((int)ptrNext + Marshal.SizeOf(typeof(RGBQUAD))); } } This causes Renderstream to return "No combination of intermediate filters could be found to make the connection." Please help! Thanks.

  • Problem with bootstrap loader and kernel

    - by dboarman-FissureStudios
    We are working on a project to learn how to write a kernel and learn the ins and outs. We have a bootstrap loader written and it appears to work. However we are having a problem with the kernel loading. I'll start with the first part: bootloader.asm: [BITS 16] [ORG 0x0000] ; ; all the stuff in between ; ; the bottom of the bootstrap loader datasector dw 0x0000 cluster dw 0x0000 ImageName db "KERNEL SYS" msgLoading db 0x0D, 0x0A, "Loading Kernel Shell", 0x0D, 0x0A, 0x00 msgCRLF db 0x0D, 0x0A, 0x00 msgProgress db ".", 0x00 msgFailure db 0x0D, 0x0A, "ERROR : Press key to reboot", 0x00 TIMES 510-($-$$) DB 0 DW 0xAA55 ;************************************************************************* The bootloader.asm is too long for the editor without causing it to chug and choke. In addition, the bootloader and kernel do work within bochs as we do get the message "Welcome to our OS". Anyway, the following is what we have for a kernel at this point. kernel.asm: [BITS 16] [ORG 0x0000] [SEGMENT .text] ; code segment mov ax, 0x0100 ; location where kernel is loaded mov ds, ax mov es, ax cli mov ss, ax ; stack segment mov sp, 0xFFFF ; stack pointer at 64k limit sti mov si, strWelcomeMsg ; load message call _disp_str mov ah, 0x00 int 0x16 ; interrupt: await keypress int 0x19 ; interrupt: reboot _disp_str: lodsb ; load next character or al, al ; test for NUL character jz .DONE mov ah, 0x0E ; BIOS teletype mov bh, 0x00 ; display page 0 mov bl, 0x07 ; text attribute int 0x10 ; interrupt: invoke BIOS jmp _disp_str .DONE: ret [SEGMENT .data] ; initialized data segment strWelcomeMsg db "Welcome to our OS", 0x00 [SEGMENT .bss] ; uninitialized data segment Using nasm 2.06rc2 I compile as such: nasm bootloader.asm -o bootloader.bin -f bin nasm kernel.asm -o kernel.sys -f bin We write bootloader.bin to the floppy as such: dd if=bootloader.bin bs=512 count=1 of/dev/fd0 We write kernel.sys to the floppy as such: cp kernel.sys /dev/fd0 As I stated, this works in bochs. But booting from the floppy we get output like so: Loading Kernel Shell ........... ERROR : Press key to reboot Other specifics: OpenSUSE 11.2, GNOME desktop, AMD x64 Any other information I may have missed, feel free to ask. I tried to get everything in here that would be needed. If I need to, I can find a way to get the entire bootloader.asm posted somewhere. We are not really interested in using GRUB either for several reasons. This could change, but we want to see this boot successful before we really consider GRUB.

  • South migration error: NoMigrations exception for django.contrib.auth

    - by danpalmer
    I have been using South on my project for a while, but I recently did a huge amount of development and changed development machine and I think something messed up in the process. The project works fine, but I can't apply migrations.

I ran 'easy_install -U South' just to make sure. Thanks for any help that you can provide. I really appreciate it.

  • Scheme Formatting Help

    - by Logan
    I've been working on a project for school that takes functions from a class file and turns them into object/classes. The assignment is all about object oriented programming in scheme. My problem however is that my code doesn't format right. The output it gives me whenever I give it a file to pass in wraps the methods of the class in a list, making it so that the class never really gets declared. I can't for the life of me figure out how to get the parenthesis wrapping the method list to remove. I would really appreciate any help. Below is the code and the class file. ;;;; PART1 --- A super-easy set of classes. Just models points and lines.

  • IDataServiceMetadataProvider - Entities dont show up in $metadata.

    - by TomTom
    I am trying to write our own RIA services provider to expose data from a server that I access via ODBC. I follow th eguidelines set out at http://blogs.msdn.com/alexj/archive/2010/03/02/creating-a-data-service-provider-part-9-un-typed.aspx I have written our own IDataServiceMetadataProvider / IDataServiceQueryProvider pair and get no errors on what i do. I am putting in a resource set like this: ResourceType tableType = new ResourceType( typeof(Dictionary<string, object>), ResourceTypeKind.EntityType, null, "Martini", table_name, false ); tableType.CanReflectOnInstanceType = false; var prodKey = new ResourceProperty( "Key", ResourcePropertyKind.Key | ResourcePropertyKind.Primitive, ResourceType.GetPrimitiveResourceType(typeof(int)) ); prodKey.CanReflectOnInstanceTypeProperty = false; tableType.AddProperty(prodKey); var prodName = new ResourceProperty( "Name", ResourcePropertyKind.Primitive, ResourceType.GetPrimitiveResourceType(typeof(string)) ); prodName.CanReflectOnInstanceTypeProperty = false; tableType.AddProperty(prodName); _MetaDataProvider.AddResourceType(tableType); _MetaDataProvider.AddResourceSet(new ResourceSet(table_name, tableType)); I see the requests coming in for enumerating the resource sets. I check them there in a breakpoint, and the resource set and the type is there, with all properties. Still, the output I get is: <?xml version="1.0" encoding="utf-8" standalone="yes" ?> - <service xml:base="http://localhost:2377/MartiniData.svc/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:app="http://www.w3.org/2007/app" xmlns="http://www.w3.org/2007/app"> - <workspace> <atom:title>Default</atom:title> </workspace> </service> And for the $metadata version: <?xml version="1.0" encoding="utf-8" standalone="yes" ?> - <edmx:Edmx Version="1.0" xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx"> - <edmx:DataServices xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" m:DataServiceVersion="1.0"> - <Schema Namespace="Martini" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns="http://schemas.microsoft.com/ado/2007/05/edm"> <EntityContainer Name="Martini" m:IsDefaultEntityContainer="true" /> </Schema> </edmx:DataServices> </edmx:Edmx> The actual metadata for the types never shows up, no error is shown. pretty frustrating. Anyone any idea?

  • Eclipselink read complex object model in an ordered way

    - by Raven
    Hi, I need to read a complex model in an ordered way with eclipselink. The order is mandantory because it is a huge database and I want to have an output of a small portion of the database in a jface tableview. Trying to reorder it in the loading/quering thread takes too long and ordering it in the LabelProvider blocks the UI thread too much time, so I thought if Eclipselink could be used that way, that the database will order it, it might give me the performance I need. Unfortunately the object model can not be changed :-( The model is something like: @SuppressWarnings("serial") @Entity public class Thing implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; @OneToMany(cascade=CascadeType.ALL) @PrivateOwned private List<Property> properties = new ArrayList<Property>(); ... // getter and setter following here } public class Property implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; @OneToOne private Item item; private String value; ... // getter and setter following here } public class Item implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; .... // getter and setter following here } // Code end In the table view the y-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Thing m ORDER BY m.name ASC"); using the "name" attribute from the Thing objects as label. In the table view the x-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Item m ORDER BY m.name ASC"); using the "name" attribute from the Item objects as label. Each cell has the value Things.getProperties().get[x].getValue() Unfortunately the list "properties" is not ordered, so the combination of cell value and x-axis column number (x) is not necessarily correct. Therefore I need to order the list "properties" in the same way as I ordered the labeling of the x-axis. And exactly this is the thing I dont know how it is done. So querying for the Thing objects should return the list "properties" "ORDER BY name ASC" but of the "Item"s objects. My ideas are something like having a query with two JOINs. Joing Things with Property and with Item but somehow I was unable to get it to work yet. Thank you for your help and your ideas to solve this riddle.

  • How do I work around this problem creating a virtualenv environment with a custom-build Python?

  • Prevent command window showing when NAnt compiling windows forms application

    I have been playing with creating little windows forms apps without visual studio. I create my source in Notepad++ and compile with a NAnt build file.

  • Does weak typing offer any advantages?

    - by sub
    Don't confuse this with static vs. dynamic typing! You all know JavaScripts/PHPs infamous type systems: PHP example: echo "123abc"+2; // 125 - the reason for this is explained // in the PHP docs but still: This hurts echo "4"+1; // 5 - Oh please echo "ABC"*5; // 0 - WTF // That's too much, seriously now. // This here might be actually a use for weak typing, but no - // it has to output garbage. JavaScript example: // A good old JavaScript, maybe you'll do better? alert("4"+1); // 51 - Oh come on. alert("abc"*3); // NaN - What the... // Have your creators ever heard of the word "consistence"? Python example: # Python's type system is actually a mix # It spits errors on senseless things like the first example below AND # allows intelligent actions like the second example. >>> print("abc"+1) Traceback (most recent call last): File "<pyshell#2>", line 1, in <module> print("abc"+1) TypeError: Can't convert 'int' object to str implicitly >>> print("abc"*5) abcabcabcabcabc Ruby example: puts 4+"1" // Type error - as supposed puts "abc"*4 // abcabcabcabc - makes sense After these examples it should be clear that PHP/JavaScript probably have the most inconsistent type systems out there. This is a fact and really not subjective. Now when having a closer look at the type systems of Ruby and Python it seems like they are having a much more intelligent and consistent type system. I think these examples weren't really necessary as we all know that PHP/JavaScript have a weak and Python/Ruby have a strong type system. I just wanted to mention why I'm asking this. Now I have two questions: When looking at those examples, what are the advantages of PHPs and JavaScripts type systems? I can only find downsides: They are inconsistent and I think we know that this is not good Types conversions are hardly controllable Bugs are more likely to happen and much harder to spot Do you prefer one of the both systems? Why? Personally I have worked with PHP, JavaScript and Python so far and must say that Pythons type system has really only advantages over PHPs and JavaScripts. Does anybody here not think so? Why then?

  • How Do I Prevent Rails From Treating Updated Nested Attributes Differently From New Nested Attribute

    - by James
    I am using rails3 beta3 and couchdb via couchrest. I am not using active record. I want to add multiple "Sections" to a "Guide" and add and remove sections dynamically via a little javascript. I have looked at all the screencasts by Ryan Bates and they have helped immensely. The only difference is that I want to save all the sections as an array of sections instead of individual sections. Basically like this: "sections" => [{"title" => "Foo1", "content" => "Bar1"}, {"title" => "Foo2", "content" => "Bar2"}] So, basically I need the params hash to look like that when the form is submitted. When I create my form I am doing the following: <%= form_for @guide, :url => { :action => "create" } do |f| %> <%= render :partial => 'section', :collection => @guide.sections %> <%= f.submit "Save" %> <% end %> And my section partial looks like this: <%= fields_for "sections[]", section do |guide_section_form| %> <%= guide_section_form.text_field :section_title %> <%= guide_section_form.text_area :content, :rows => 3 %> <% end %> Ok, so when I create the guide with sections, it is working perfectly as I would like. The params hash is giving me a sections array just like I would want. The problem comes when I want edit guide/sections and save them again because rails is inserting the id of the guide in the id and name of each form field, which is screwing up the params hash on form submission. Just to be clear, here is the raw form output for a new resource: <input type="text" size="30" name="sections[][section_title]" id="sections__section_title"> <textarea rows="3" name="sections[][content]" id="sections__content" cols="40"></textarea> And here is what it looks like when editing an existing resource: <input type="text" value="Foo1" size="30" name="sections[cd2f2759895b5ae6cb7946def0b321f1][section_title]" id="sections_cd2f2759895b5ae6cb7946def0b321f1_section_title"> <textarea rows="3" name="sections[cd2f2759895b5ae6cb7946def0b321f1][content]" id="sections_cd2f2759895b5ae6cb7946def0b321f1_content" cols="40">Bar1</textarea> How do I force rails to always use the new resource behavior and not automatically add the id to the name and value. Do I have to create a custom form builder? Is there some other trick I can do to prevent rails from putting the id of the guide in there? I have tried a bunch of stuff and nothing is working. Thanks in advance!

  • timeIntervalSinceDate Accuracy

    - by mmccomb
    I've been working on a game with an engine that updates 20 times per seconds. I've got to point now where I want to start getting some performance figures and tweak the rendering and logic updates. In order to do so I started to add some timing code to my game loop, implemented as follows... NSDate* startTime = [NSDate date]; // Game update logic here.... // Also timing of smaller internal events NSDate* endTime = [NSDate date]; [endTime timeIntervalSinceDate:startTime]; I noticed however that when I timed blocks within the outer timing logic that the time they took to execute did not sum up to match the overall time taken. So I wrote a small unit test to demonstrate the problem in which I time the overall time taken to complete the test and then 10 smaller events, here it is... - (void)testThatSumOfTimingsMatchesOverallTiming { NSDate* startOfOverallTime = [NSDate date]; // Variable to hold summation of smaller timing events in the upcoming loop... float sumOfIndividualTimes = 0.0; NSTimeInterval times[10] = {0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0}; for (int i = 0; i < 10; i++) { NSDate* startOfIndividualTime = [NSDate date]; // Kill some time... sleep(1); NSDate* endOfIndividualTime = [NSDate date]; times[i] = [endOfIndividualTime timeIntervalSinceDate:startOfIndividualTime]; sumOfIndividualTimes += times[i]; } NSDate* endOfOverallTime = [NSDate date]; NSTimeInterval overallTimeTaken = [endOfOverallTime timeIntervalSinceDate:startOfOverallTime]; NSLog(@"Sum of individual times: %fms", sumOfIndividualTimes); NSLog(@"Overall time: %fms", overallTimeTaken); STAssertFalse(TRUE, @""); } And here's the output... Sum of individual times: 10.001377ms Overall time: 10.016834ms Which illustrates my problem quite clearly. The overall time was 0.000012ms but the smaller events took only 0.000001ms. So what happened to the other 0.000011ms? Is there anything that looks particularly wrong with my code? Or is there an alternative timing mechanism I should use?

  • Stack Overflow problem in a recursive program in C

    Hi all, I am getting a stack overflow in one of the recursive functions i am running.. Here is the code.. void* buddyMalloc(int req_size) { // Do something here return buddy_findout(original_index,req_size); // This is the recursive call } void *buddy_findout(int current_index,int req_size) { char *selected = NULL; if(front!=NULL) { if(current_index==original_index) { // Do something here return selected; } else { // Do Something here return buddy_findout(current_index+1,req_size); } } else { return buddy_findout(current_index-1,req_size); } } Consider the initial value of index to be 4. and it first do index-1 till it reaches 0 index. and then it comes back to index 4 by incrementing..This is wht i want to implement.

  • Get HDD (and NOT Volume) Serial Number on Vista Ultimate 64 bit

    Hi all. I was once looking for getting the HDD serial number without using WMI, and I found it. The code I found and posted on StackOverFlow.com works very well on 32 bit Windows, both XP and Vista. The trouble only begins when I try to get the serail number on 64 bit OSs (Vista Ultimate 64, specifically). The code returns String.Empty, or a Space all the time. Anyone got an idea how to fix this? EDIT: I used the tools Dave Cluderay suggested, with interesting results: Here is the output from DiskId32, on Windows XP SP2 32-bit: To get all details use "diskid32 /d" Trying to read the drive IDs using physical access with admin rights Drive 0 - Primary Controller - - Master drive Drive Model Number________________: [MAXTOR STM3160215AS] Drive Serial Number_______________: [ 6RA26XK3] Drive Controller Revision Number__: [3.AAD] Controller Buffer Size on Drive___: 2097152 bytes Drive Type________________________: Fixed Drive Size________________________: 160041885696 bytes Trying to read the drive IDs using the SCSI back door Drive 4 - Tertiary Controller - - Master drive Drive Model Number________________: [MAXTOR STM3160215AS] Drive Serial Number_______________: [ 6RA26XK3] Drive Controller Revision Number__: [3.AAD] Controller Buffer Size on Drive___: 2097152 bytes Drive Type________________________: Fixed Drive Size________________________: 160041885696 bytes Trying to read the drive IDs using physical access with zero rights **** STORAGE_DEVICE_DESCRIPTOR for drive 0 **** Vendor Id = [] Product Id = [MAXTOR STM3160215AS] Product Revision = [3.AAD] Serial Number = [] **** DISK_GEOMETRY_EX for drive 0 **** Disk is fixed DiskSize = 160041885696 Trying to read the drive IDs using Smart Drive 0 - Primary Controller - - Master drive Drive Model Number________________: [MAXTOR STM3160215AS] Drive Serial Number_______________: [ 6RA26XK3] Drive Controller Revision Number__: [3.AAD] Controller Buffer Size on Drive___: 2097152 bytes Drive Type________________________: Fixed Drive Size________________________: 160041885696 bytes Hard Drive Serial Number__________: 6RA26XK3 Hard Drive Model Number___________: MAXTOR STM3160215AS And DiskId32 run on Windows Vista Ultimate 64-bit: To get all details use "diskid32 /d" Trying to read the drive IDs using physical access with admin rights Trying to read the drive IDs using the SCSI back door Trying to read the drive IDs using physical access with zero rights **** STORAGE_DEVICE_DESCRIPTOR for drive 0 **** Vendor Id = [MAXTOR S] Product Id = [TM3160215AS] Product Revision = [3.AA] Serial Number = [] **** DISK_GEOMETRY_EX for drive 0 **** Disk is fixed DiskSize = 160041885696 Trying to read the drive IDs using Smart Hard Drive Serial Number__________: Hard Drive Model Number___________: Notice how much lesser the information is on Vista, and how the Serial Number is not returned.

  • My block is not retaining some of its objects

    - by Drew Crawford
    From the Blocks documentation: In a reference-counted environment, by default when you reference an Objective-C object within a block, it is retained. This is true even if you simply reference an instance variable of the object. I am trying to implement a completion handler pattern, where a block is given to an object before the work is performed and the block is executed by the receiver after the work is performed. Since I am being a good memory citizen, the block should own the objects it references in the completion handler and then they will be released when the block goes out of scope. I know enough to know that I must copy the block to move it to the heap since the block will survive the stack scope in which it was declared. However, one of my objects is getting deallocated unexpectedly. After some playing around, it appears that certain objects are not retained when the block is copied to the heap, while other objects are. I am not sure what I am doing wrong. Here's the smallest test case I can produce: typedef void (^ActionBlock)(UIView*); In the scope of some method: NSObject *o = [[[NSObject alloc] init] autorelease]; mailViewController = [[[MFMailComposeViewController alloc] init] autorelease]; NSLog(@"o's retain count is %d",[o retainCount]); NSLog(@"mailViewController's retain count is %d",[mailViewController retainCount]); ActionBlock myBlock = ^(UIView *view) { [mailViewController setCcRecipients:[NSArray arrayWithObjects:@"[email protected]",nil]]; [o class]; }; NSLog(@"mailViewController's retain count after the block is %d",[mailViewController retainCount]); NSLog(@"o's retain count after the block is %d",[o retainCount]); Block_copy(myBlock); NSLog(@"o's retain count after the copy is %d",[o retainCount]); NSLog(@"mailViewController's retain count after the copy is %d",[mailViewController retainCount]); I expect both objects to be retained by the block at some point, and I certainly expect their retain counts to be identical. Instead, I get this output: o's retain count is 1 mailViewController's retain count is 1 mailViewController's retain count after the block is 1 o's retain count after the block is 1 o's retain count after the copy is 2 mailViewController's retain count after the copy is 1 o (subclass of NSObject) is getting retained properly and will not go out of scope. However mailViewController is not retained and will be deallocated before the block is run, causing a crash.

  • Complex.pm taking up a lot of time

    - by synapz
    While trying to profile my perl program, I find that Complex.pm is taking up a lot of time with what looks like some kind of warning.

  • NSXMLParser Memory Allocation Efficiency for the iPhone

    - by Staros
    Hello, I've recently been playing with code for an iPhone app to parse XML. Sticking to Cocoa, I decided to go with the NSXMLParser class. The app will be responsible for parsing 10,000+ "computers", all which contain 6 other strings of information. For my test, I've verified that the XML is around 900k-1MB in size. My data model is to keep each computer in an NSDictionary hashed by a unique identifier. Each computer is also represented by a NSDictionary with the information. So at the end of the day, I end up with a NSDictionary containing 10k other NSDictionaries. The problem I'm running into isn't about leaking memory or efficient data structure storage. When my parser is done, the total amount of allocated objects only does go up by about 1MB. The problem is that while the NSXMLParser is running, my object allocation is jumping up as much as 13MB. I could understand 2 (one for the object I'm creating and one for the raw NSData) plus a little room to work, but 13 seems a bit high. I can't imaging that NSXMLParser is that inefficient. Thoughts? Code... The code to start parsing... NSXMLParser *parser = [[NSXMLParser alloc] initWithData: data]; [parser setDelegate:dictParser]; [parser parse]; output = [[dictParser returnDictionary] retain]; [parser release]; [dictParser release]; And the parser's delegate code... -(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict { if(mutableString) { [mutableString release]; mutableString = nil; } mutableString = [[NSMutableString alloc] init]; } -(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if(self.mutableString) { [self.mutableString appendString:string]; } } -(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if([elementName isEqualToString:@"size"]){ //The initial key, tells me how many computers returnDictionary = [[NSMutableDictionary alloc] initWithCapacity:[mutableString intValue]]; } if([elementName isEqualToString:hashBy]){ //The unique identifier if(mutableDictionary){ [mutableDictionary release]; mutableDictionary = nil; } mutableDictionary = [[NSMutableDictionary alloc] initWithCapacity:6]; [returnDictionary setObject:[NSDictionary dictionaryWithDictionary:mutableDictionary] forKey:[NSMutableString stringWithString:mutableString]]; } if([fields containsObject:elementName]){ //Any of the elements from a single computer that I am looking for [mutableDictionary setObject:mutableString forKey:elementName]; } } Everything initialized and released correctly. Again, I'm not getting errors or leaking. Just inefficient. Thanks for any thoughts!
