• Improve Exception Safety In Your C++ Applications by Annotating Functions That Don't Throw ...

  Your compiler assumes by default that almost every function might throw an exception. As a result, it might generate suboptimal code. C++0x now lets you explicitly annotate functions that never throw with the [[nothrow]] attribute. Find out how to use this attribute to write efficient and self-documenting code.

• I am trying to zip files individually, but the file type is unknown

  - by Jason Mander

  I am trying to zip some files with an unknown file type individually. I am using the following code in a batch script to do that: @ECHO OFF FOR %%A IN (bestbuy*nat*component.cpi*) DO "C:\Program Files\7-Zip\7z.exe" a -mx9 -m0=lzma2:d256m "%%~nA.7z" "%%A" The code will compress files individually ONLY if the file has an extension. Unfortunately the files that I have don't have any extension. In the code I am trying to zip files by doing a pattern match, the files are getting compressed into ONE file (which I do not want, I want each file compressed individually). Why does this code create separate zip files when the files have an extension (for example if I add .txt to the end of the files) and when there is no extension the code creates one zipped file. Can anyone please help me with the code to compress files with unknown file type so that each file gets compressed individually Your help would be greatly appreciated. Jason

• Why did cherokee-admin-launcher crash?

  - by DarenW

  I'm trying out the Cherokee http server on a seemingly fine machine. Following simple set-up instructions, I tried running cherokee-admin-launcher but it printed error messages and hung up. Ctrl-C did not kill it; I had to kill -9 it from another xterm. OTOH, cherokee-admin ran fine (or at least got a lot further). What is the problem with python and cherokee-admin-launcher, and how to fix it? [root@iron rc.d]# cherokee-admin-launcher Checking TCP port 9090 availability..

• stdout and key press

  - by Jack

  Hi, when in console, if I press a key, some interrupt controller sends code of that key to CPU, which looks into some table and than represent that keypress by printing some charracter to stdout. But, is keyboard sending an ASCII code of that key, or just some standardised code? Since there is so many languages and extra characters, OS must further translate its code into some character according to user selected scheme, I guess. I ask, becouse I am from Czech Republic, and we use some characters that do not exists in standart ASCII code. So I was thinking, if I enter this character into a console, and then print it, lets say in C++ using cin and cout, and I have set locale to Czech, stdin must actually send some non-ASCII code of the character I pressed to input stream. Am I right?

• Extract Certs from Apache

  - by user271619

  Recently I've had to uninstall a single Self-Signed SSL Certificate from one of my Apache boxes, specifically for an outside party. That's not really a problem for me, since it was easy. What confuses me is how they knew I had a self-signed certificate. The domain I provided them was not related to the domain with the self-signed certificate. Does this mean Apache publicizes the Virtual hosts in the httpd.conf file? I asked the outside party what software they used to extract information from my server, and they provided this GitHub link: https://gist.github.com/4ndrej/4547029 I figured I'd ask the community first, before I attempt installing the Java program.

• Shuttle FB51 mobo does not boot with external USB drive attached [closed]

  - by user127236

  I am repurposing an old Alienware desktop as a home media server. The PC is based on the Shuttle FB51 motherboard. The BIOS is a Phoenix Version 6.00 PG, release date 12/16/2002. I have loaded Ubuntu 12.04 LTS on the internal hard drive. I am using a Western Digital WD Elements 1.5 TB USB 2.0 Desktop External Hard Drive for media storage. When the external drive is plugged in and the PC is powered on, it freezes very early in the BIOS self-test, even before it begins the memory test. If I unplug the drive, the self-test proceeds without further problems. I can plug the USB drive back in when the self-test is complete, and Ubuntu will boot and find the external drive normally. I've tried several changes to the BIOS setup without finding a cure for the boot issue. Any assistance gratefully accepted. JGB

• CGI Script not running in PHP file

  - by Unykvis

  I have a CGI script in the server called script.cgi and I have added the following code to the domain vhost: Action add-footer /cgi-bin/script.cgi AddHandler add-footer .htm .html I have change it to: Action add-footer /cgi-bin/script.cgi AddHandler add-footer .htm .html .php If the page is HTML the code will run but if the page is PHP the code will not run. Is there any code I need to add to the vhost so that PHP files can run this script? **EDITED:** I want to "inject" an HTML code in every possible page of the server this includes HTML and PHP files. The code only works for html files and I don't know why.

• EXCEL function working like SQL group by + count(distinct *)?

  - by Solo

  Suppose I have an EXCEL sheet with below data CODE (COL A) | VALUE (COL B) ============================== A01 | 10 A01 | 20 A01 | 30 A01 | 10 B01 | 30 B01 | 30 Is there an EXCEL function working like .. SELECT CODE, count (Distinct *) FROM TABLE GROUP BY CODE CODE | Distinct Count of Value =================================== A01 | 3 B01 | 1 or, better yet, Can we have an excel formula pasted in Column C to get something like this: CODE (COL A) | VALUE (COL B) | DISTINCT VALUE COUNT WITH MATCHING CODE (COL C) =============================================================================== A01 | 10 | 3 A01 | 20 | 3 A01 | 30 | 3 A01 | 10 | 3 B01 | 30 | 1 B01 | 30 | 1 I know I can use pivot table to get this result easily. However due to reporting requirements I have to append the "distinct count" column to the excel sheet, hence pivot table is not an option. My last resort is to use Excel Macro (Which is fine), but before that I would like to learn whether excel functions can accomplish this kind of task. Many thanks!

• Act on click of a button on the Nav Bar for moreNavigationController -- Can't pushviewcontroller

  - by Jann

  Okay, here is my issue: My app has a display of categories in the tab bar at the bottom of the iPhoneOS screen. This only allows 5 categories before it presents the MORE button. I have over 25 (please do not answer this by saying: "Rethink your application...etc" -- that was rudely said before. They are food, drink, etc categories and cannot be changed). I want to allow the user to put their favorites on the home page. The Apple moreNavigationController editing system only allows 20 tab bar items to be rearranged due to space constraints on the editing page. This is not enough so i need to implement my own Editing screen. I set the rightBarButtonItem to nil and created my own. Using NSLog, i can see the "click" happens when clicking the EDIT button, but I cannot push using pushViewController. Nothing happens. I think it has something to do with the navigationController I am addressing...but i am not sure. ps: This all happens in my App Delegate which DOES act as both UITabBarControllerDelegate & UINavigationControllerDelegate. I tried to do the following: - ( void )navigationController:( UINavigationController * )navigationController_local willShowViewController:( UIViewController * )viewController_local animated:( BOOL )animated { UIViewController * currentController = navigationController_local.visibleViewController; UIViewController * nextController = viewController_local; // Do whatever here. NSLog(@"Nav contoller willShowViewController fired\n'%@'\n'%@'\nThere are currently: %d views on the stack\n",currentController,nextController,[self.navigationController.viewControllers count]); if ( [nextController isKindOfClass:NSClassFromString(@"UIMoreListController")]) { UINavigationBar *morenavbar = navigationController_local.navigationBar; UINavigationItem *morenavitem = morenavbar.topItem; morenavitem.rightBarButtonItem = nil; NSLog(@"Is a UIMoreListController\n"); UIBarButtonItem *editTabBarButton = [[UIBarButtonItem alloc] initWithTitle:@"Edit" style:UIBarButtonItemStylePlain target:self action:@selector(editTabBar:)]; morenavitem.rightBarButtonItem = editTabBarButton; [editTabBarButton release]; } } This works to place an EDIT button at the top right of the screen -- mimicking Apple's look and feel... but when that button is clicked, you cannot exit the darn moreNavigationController. I have tried many things. UIAlerts work, etc...but pushing (or popping -- even popping to root view) a view controller on the stack does not. - (void) editTabBar:(id)sender { NSLog(@"clicked edit tabbar\n"); NSLog(@"Total count of controllers: %d\n",[self.navigationController.viewControllers count]); TabBarViewController *tabBarViewController2 = [[TabBarViewController alloc] initWithNibName:@"TabBarView" bundle:nil]; tabBarViewController2.navigationItem.title=@"Edit Tab Bar"; [self.navigationController pushViewController:tabBarViewController2 animated:YES]; [tabBarViewController2 release]; NSLog(@"finished edit tabbar\n"); } If you click the edit button on the moreNavigationController's display page, you get the log entries like expected AND (this is strange) the views on the stack climbs -- but no page change occurs. I marked it down to not using the correct navigation controller...but I am lost on how to find which one TO use. this is a weird one too. In the edit function if i just do this: - (void) editTabBar:(id)sender { self.tabBarController.selectedIndex = 0; } It DOES take me home (to tabbarcontroller 0) BUT doing this: - (void) editTabBar:(id)sender { [self.navigationController popToRootViewControllerAnimated:YES]; } does not work. Does the moreNavigationController have some special quality that screws with the rest of the system?

• How to have two UIPickerViews together in one ViewController?

  - by 0SX

  I'm trying to put 2 UIPickerViews together in one ViewController. Each UIPickerView has different data arrays. I'm using interface builder to link the pickers up. I know I'll have to use separate delegates and dataSources but I can't seem to hook everything up with interface builder correctly. Here's all my code: pickerTesting.h #import <UIKit/UIKit.h> #import "picker2DataSource.h" @interface pickerTestingViewController : UIViewController <UIPickerViewDelegate, UIPickerViewDataSource>{ IBOutlet UIPickerView *picker; IBOutlet UIPickerView *picker2; NSMutableArray *pickerViewArray; } @property (nonatomic, retain) IBOutlet UIPickerView *picker; @property (nonatomic, retain) IBOutlet UIPickerView *picker2; @property (nonatomic, retain) NSMutableArray *pickerViewArray; @end pickerTesting.m #import "pickerTestingViewController.h" @implementation pickerTestingViewController @synthesize picker, picker2, pickerViewArray; - (void)viewDidLoad { [super viewDidLoad]; pickerViewArray = [[NSMutableArray alloc] init]; [pickerViewArray addObject:@" 100 "]; [pickerViewArray addObject:@" 200 "]; [pickerViewArray addObject:@" 400 "]; [pickerViewArray addObject:@" 600 "]; [pickerViewArray addObject:@" 1000 "]; [picker selectRow:1 inComponent:0 animated:NO]; picker2.delegate = self; picker2.dataSource = self; } - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)picker; { return 1; } - (void)pickerView:(UIPickerView *)picker didSelectRow:(NSInteger)row inComponent:(NSInteger)component { } - (NSInteger)pickerView:(UIPickerView *)picker numberOfRowsInComponent:(NSInteger)component; { return [pickerViewArray count]; } - (NSString *)pickerView:(UIPickerView *)picker titleForRow:(NSInteger)row forComponent:(NSInteger)component; { return [pickerViewArray objectAtIndex:row]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)viewDidUnload { // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (void)dealloc { [super dealloc]; } @end And I have a separate class for the other datasource. picker2DataSource.h @interface picker2DataSource : NSObject <UIPickerViewDataSource, UIPickerViewDelegate> { NSMutableArray *customPickerArray; } @property (nonatomic, retain) NSMutableArray *customPickerArray; @end picker2DataSource.m #import "picker2DataSource.h" @implementation picker2DataSource @synthesize customPickerArray; - (id)init { // use predetermined frame size self = [super init]; if (self) { customPickerArray = [[NSMutableArray alloc] init]; [customPickerArray addObject:@" a "]; [customPickerArray addObject:@" b "]; [customPickerArray addObject:@" c "]; [customPickerArray addObject:@" d "]; [customPickerArray addObject:@" e "]; } return self; } - (void)dealloc { [customPickerArray release]; [super dealloc]; } - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)picker2; { return 1; } - (void)pickerView:(UIPickerView *)picker2 didSelectRow:(NSInteger)row inComponent:(NSInteger)component { } - (NSInteger)pickerView:(UIPickerView *)picker2 numberOfRowsInComponent:(NSInteger)component; { return [customPickerArray count]; } - (NSString *)pickerView:(UIPickerView *)picker2 titleForRow:(NSInteger)row forComponent:(NSInteger)component; { return [customPickerArray objectAtIndex:row]; } @end Any help or code examples would be great.

• uiscrollview not switching image subviews

  - by nickthedude

  I'm building a comic viewer app, that consists of two view controllers, the root viewcontroller basically displays a view where a user decides what comic they want to read by pressing a button. The second viewController actually displays the comic as a uiscrollview with a toolbar and a title at the top. So the problem I am having is that the comic image panels themselves are not changing from whatever the first comic you go to if you select another comic after viewing the first one. The way I set it up, and I admit it's not exactly mvc, so please don't hate, anyway the way I set it up is each comic uiscrollview consists of x number of jpg images where each comic set's image names have a common prefix and then a number like 'funny1.jpg', 'funny2.jpg', 'funny3.jpg' and 'soda1.jpg', 'soda2.jpg', 'soda3.jpg', etc... so when a user selects a comic to view in the root controller it makes a call to the delegate and sets ivars on instances of the comicviewcontroller that belongs to the delegate (mainDelegate.comicViewController.property) I set the number of panels in that comic, the comic name for the title label, and the image prefix. The number of images changes(or at least the number that you can scroll through), and the title changes but for some reason the images are the same ones as whatever comic you clicked on initially. I'm basing this whole app off of the 'scrolling' code sample from apple. I thought if I added a viewWillAppear:(BOOL) animated call to the comicViewController everytime the user clicked the button that would fix it but it didn't, after all that is where the scrollview is laid out. Anyway here is some code from each of the two controllers: RootController: -(IBAction) launchComic2{ AppDelegate *mainDelegate = [(AppDelegate *) [UIApplication sharedApplication] delegate]; mainDelegate.myViewController.comicPageCount = 3; mainDelegate.myViewController.comicTitle.text = @"\"Death by ETOH\""; mainDelegate.myViewController.comicImagePrefix = @"etoh"; [mainDelegate.myViewController viewWillAppear:YES]; [mainDelegate.window addSubview: mainDelegate.myViewController.view]; comicViewController: -(void) viewWillAppear:(BOOL)animated { self.view.backgroundColor = [UIColor viewFlipsideBackgroundColor]; // 1. setup the scrollview for multiple images and add it to the view controller // // note: the following can be done in Interface Builder, but we show this in code for clarity [scrollView1 setBackgroundColor:[UIColor whiteColor]]; [scrollView1 setCanCancelContentTouches:NO]; scrollView1.indicatorStyle = UIScrollViewIndicatorStyleWhite; scrollView1.clipsToBounds = YES; // default is NO, we want to restrict drawing within our scrollview scrollView1.scrollEnabled = YES; // pagingEnabled property default is NO, if set the scroller will stop or snap at each photo // if you want free-flowing scroll, don't set this property. scrollView1.pagingEnabled = YES; // load all the images from our bundle and add them to the scroll view NSUInteger i; for (i = 1; i <= self.comicPageCount; i++) { NSString *imageName = [NSString stringWithFormat:@"%@%d.jpg", self.comicImagePrefix, i]; NSLog(@"%@%d.jpg", self.comicImagePrefix, i); UIImage *image = [UIImage imageNamed:imageName]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; // setup each frame to a default height and width, it will be properly placed when we call "updateScrollList" CGRect rect = imageView.frame; rect.size.height = kScrollObjHeight; rect.size.width = kScrollObjWidth; imageView.frame = rect; imageView.tag = i; // tag our images for later use when we place them in serial fashion [scrollView1 addSubview:imageView]; [imageView release]; } [self layoutScrollImages]; // now place the photos in serial layout within the scrollview } - (void)layoutScrollImages { UIImageView *view = nil; NSArray *subviews = [scrollView1 subviews]; // reposition all image subviews in a horizontal serial fashion CGFloat curXLoc = 0; for (view in subviews) { if ([view isKindOfClass:[UIImageView class]] && view.tag 0) { CGRect frame = view.frame; frame.origin = CGPointMake(curXLoc, 0); view.frame = frame; curXLoc += (kScrollObjWidth); } } // set the content size so it can be scrollable [scrollView1 setContentSize:CGSizeMake((self.comicPageCount * kScrollObjWidth), [scrollView1 bounds].size.height)]; } Any help would be appreciated on this.

• Dynamic model choice field in django formset using multiple select elements

  - by Aryeh Leib Taurog

  I posted this question on the django-users list, but haven't had a reply there yet. I have models that look something like this: class ProductGroup(models.Model): name = models.CharField(max_length=10, primary_key=True) def __unicode__(self): return self.name class ProductRun(models.Model): date = models.DateField(primary_key=True) def __unicode__(self): return self.date.isoformat() class CatalogItem(models.Model): cid = models.CharField(max_length=25, primary_key=True) group = models.ForeignKey(ProductGroup) run = models.ForeignKey(ProductRun) pnumber = models.IntegerField() def __unicode__(self): return self.cid class Meta: unique_together = ('group', 'run', 'pnumber') class Transaction(models.Model): timestamp = models.DateTimeField() user = models.ForeignKey(User) item = models.ForeignKey(CatalogItem) quantity = models.IntegerField() price = models.FloatField() Let's say there are about 10 ProductGroups and 10-20 relevant ProductRuns at any given time. Each group has 20-200 distinct product numbers (pnumber), so there are at least a few thousand CatalogItems. I am working on formsets for the Transaction model. Instead of a single select menu with the several thousand CatalogItems for the ForeignKey field, I want to substitute three drop-down menus, for group, run, and pnumber, which uniquely identify the CatalogItem. I'd also like to limit the choices in the second two drop-downs to those runs and pnumbers which are available for the currently selected product group (I can update them via AJAX if the user changes the product group, but it's important that the initial page load as described without relying on AJAX). What's the best way to do this? As a point of departure, here's what I've tried/considered so far: My first approach was to exclude the item foreign key field from the form, add the substitute dropdowns by overriding the add_fields method of the formset, and then extract the data and populate the fields manually on the model instances before saving them. It's straightforward and pretty simple, but it's not very reusable and I don't think it is the right way to do this. My second approach was to create a new field which inherits both MultiValueField and ModelChoiceField, and a corresponding MultiWidget subclass. This seems like the right approach. As Malcolm Tredinnick put it in a django-users discussion, "the 'smarts' of a field lie in the Field class." The problem I'm having is when/where to fetch the lists of choices from the db. The code I have now does it in the Field's __init__, but that means I have to know which ProductGroup I'm dealing with before I can even define the Form class, since I have to instantiate the Field when I define the form. So I have a factory function which I call at the last minute from my view--after I know what CatalogItems I have and which product group they're in--to create form/formset classes and instantiate them. It works, but I wonder if there's a better way. After all, the field should be able to determine the correct choices much later on, once it knows its current value. Another problem is that my implementation limits the entire formset to transactions relating to (CatalogItems from) a single ProductGroup. A third possibility I'm entertaining is to put it all in the Widget class. Once I have the related model instance, or the cid, or whatever the widget is given, I can get the ProductGroup and construct the drop-downs. This would solve the issues with my second approach, but doesn't seem like the right approach.

• translating play in HTML to python

  - by aharon

  So, I'd like to represent one of Shakespeare's plays, Hamlet, into the following objects (maybe this isn't the best representation, if so please tell me): class Play(): acts = [] ... def add_act(self, act): acts.append(act) class Act(): scenes = [] ... def add_scene(self, scene): scenes.append(scene) class Scene(): elems = [] def __init__(self, title, setting=""): ... def add_elem(self, elem): elems.append(elem) ... class StageDirection(): # elem def __init__(self, text): ... class Line(): # elem def __init__(self, id, text, character = None): ... # A None character represents a continuation from the previous line # id could be, for example, 1.1.1 There are other methods, of course, for printing and such in each of the classes. The question is, how do I get a structure based on these classes (or something like them) from HTML 4 code that looks like this: <H3>ACT I</h3> <h3>SCENE I. Elsinore. A platform before the castle.</h3> <p><blockquote> <i>FRANCISCO at his post. Enter to him BERNARDO</i> </blockquote> <A NAME=speech1><b>BERNARDO</b></a> <blockquote> <A NAME=1.1.1>Who's there?</A><br> </blockquote> <A NAME=speech2><b>FRANCISCO</b></a> <blockquote> <A NAME=1.1.2>Nay, answer me: stand, and unfold yourself.</A><br> </blockquote> <A NAME=speech3><b>BERNARDO</b></a> <blockquote> <A NAME=1.1.3>Long live the king!</A><br> </blockquote> <A NAME=speech4><b>FRANCISCO</b></a> <blockquote> <A NAME=1.1.4>Bernardo?</A><br> </blockquote> <A NAME=speech5><b>BERNARDO</b></a> <blockquote> <A NAME=1.1.5>He.</A><br> </blockquote> <!-- for more, see the source of shakespeare.mit.edu/hamlet/full.html --> translating that into something like this: play = Play() actI = Act() sceneI = Scene("Scene I", "Elsinore. A platform before the castle.") sceneI.add_elem(StageDirection("Francisco at his post. Enter to him Bernardo.")) sceneI.add_elem(Line("Bernardo", "Who's there?")) ... Of course, I don't expect all the code—but what libraries and, when there aren't libraries, logic should I use? Thanks. (This is for a future opensource project and me learning Python for fun—not homework.)

• Facebook Invalid OAuth access token signature trying to post an attachment to group wall from PHP

  - by Volodymyr B

  I am an administrator (manager role) of a Facebook Group. I created an app, and stored its id and secret. I want my app to be able to post something on the Facebook group's feed. But when I attempt to post, I get the error 190 Invalid OAuth access token signature, even though I able to successfully obtain the access_token with publish_stream and offline_access scopes. It has the form of NNNNNNNNNNNNNNN|XXXXXXXXXXXXXXXXXXXXXXXXXXX, where N is a number (15) and X is a letter or a number (27). What should I do more to get this accomplished? Here is the code I am using: public static function postToFB($message, $image, $link) { //Get App Token $token = self::getFacebookToken(); // Create FB Object Instance $facebook = new Facebook(array( 'appId' => self::fb_appid, 'secret' => self::fb_secret, 'cookie' => true )); //$token = $facebook->getAccessToken(); //Try to Publish on wall or catch the Facebook exception try { $attachment = array('access_token' => $token, 'message' => $message, 'picture' => $image, 'link' => $link, //'name' => '', //'caption' => '', 'description' => 'More...', //'actions' => array(array('name' => 'Action Text', 'link' => 'http://apps.facebook.com/xxxxxx/')) ); $result = $facebook->api('/'.self::fb_groupid.'/feed/', 'post', $attachment); } catch (FacebookApiException $e) { //If the post is not published, print error details echo '<pre>'; print_r($e); echo '</pre>'; } } Code which returns the token //Function to Get Access Token public static function getFacebookToken($appid = self::fb_appid, $appsecret = self::fb_secret) { $args = array( 'grant_type' => 'client_credentials', 'client_id' => $appid, 'client_secret' => $appsecret, 'redirect_uri' => 'https://www.facebook.com/connect/login_success.html', 'scope' => 'publish_stream,offline_access' ); $ch = curl_init(); $url = 'https://graph.facebook.com/oauth/access_token'; curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $args); try { $data = curl_exec($ch); } catch (Exception $exc) { error_log($exc->getMessage()); } return json_encode($data); } If I uncomment $token = $facebook->getAccessToken(); in the posting code, it gives me yet another error (#200) The user hasn't authorized the application to perform this action. The token I get using developers.facebook.com/tools/explorer/ is of another form, much longer and with it I am able to post to the group page feed. How do I do it without copy/paste from Graph API Explorer and how do I post as a group instead of posting as a user? Thanks.

• globals and locals in python exec()

  - by hawkettc

  Hi, I'm trying to run a piece of python code using exec. my_code = """ class A(object): pass print 'locals: %s' % locals() print 'A: %s' % A class B(object): a_ref = A """ global_env = {} local_env = {} my_code_AST = compile(my_code, "My Code", "exec") exec(my_code_AST, global_env, local_env) print local_env which results in the following output locals: {'A': <class 'A'>} A: <class 'A'> Traceback (most recent call last): File "python_test.py", line 16, in <module> exec(my_code_AST, global_env, local_env) File "My Code", line 8, in <module> File "My Code", line 9, in B NameError: name 'A' is not defined However, if I change the code to this - my_code = """ class A(object): pass print 'locals: %s' % locals() print 'A: %s' % A class B(A): pass """ global_env = {} local_env = {} my_code_AST = compile(my_code, "My Code", "exec") exec(my_code_AST, global_env, local_env) print local_env then it works fine - giving the following output - locals: {'A': <class 'A'>} A: <class 'A'> {'A': <class 'A'>, 'B': <class 'B'>} Clearly A is present and accessible - what's going wrong in the first piece of code? I'm using 2.6.5, cheers, Colin * UPDATE 1 * If I check the locals() inside the class - my_code = """ class A(object): pass print 'locals: %s' % locals() print 'A: %s' % A class B(object): print locals() a_ref = A """ global_env = {} local_env = {} my_code_AST = compile(my_code, "My Code", "exec") exec(my_code_AST, global_env, local_env) print local_env Then it becomes clear that locals() is not the same in both places - locals: {'A': <class 'A'>} A: <class 'A'> {'__module__': '__builtin__'} Traceback (most recent call last): File "python_test.py", line 16, in <module> exec(my_code_AST, global_env, local_env) File "My Code", line 8, in <module> File "My Code", line 10, in B NameError: name 'A' is not defined However, if I do this, there is no problem - def f(): class A(object): pass class B(object): a_ref = A f() print 'Finished OK' * UPDATE 2 * ok, so the docs here - http://docs.python.org/reference/executionmodel.html 'A class definition is an executable statement that may use and define names. These references follow the normal rules for name resolution. The namespace of the class definition becomes the attribute dictionary of the class. Names defined at the class scope are not visible in methods.' It seems to me that 'A' should be made available as a free variable within the executable statement that is the definition of B, and this happens when we call f(), but not when we use exec(). This can be more easily shown with the following - my_code = """ class A(object): pass print 'locals in body: %s' % locals() print 'A: %s' % A def f(): print 'A in f: %s' % A f() class B(object): a_ref = A """ which outputs locals in body: {'A': <class 'A'>} A: <class 'A'> Traceback (most recent call last): File "python_test.py", line 20, in <module> exec(my_code_AST, global_env, local_env) File "My Code", line 11, in <module> File "My Code", line 9, in f NameError: global name 'A' is not defined So I guess the new question is - why aren't those locals being exposed as free variables in functions and class definitions - it seems like a pretty standard closure scenario.

• data not reloading into tableview from core data on minor update

  - by Martin KS

  I've got a basic photo album application, on the first view a list of albums is displayed with a subtitle showing how many images are in each album. I've got everything working to add albums, and add images to albums. The problem is that the image count lines are accurate whenever the app loads, but I can't get them to update during execution. The following viewdidload correctly populates all lines of the tableview when the app loads: - (void)viewDidLoad { [super viewDidLoad]; // Set the title. self.title = @"Photo albums"; // Configure the add and edit buttons. self.navigationItem.leftBarButtonItem = self.editButtonItem; addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addAlbum)]; addButton.enabled = YES; self.navigationItem.rightBarButtonItem = addButton; /* Fetch existing albums. Create a fetch request; find the Album entity and assign it to the request; add a sort descriptor; then execute the fetch. */ NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Album" inManagedObjectContext:managedObjectContext]; [request setEntity:entity]; // Order the albums by name. NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"albumName" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [sortDescriptor release]; [sortDescriptors release]; // Execute the fetch -- create a mutable copy of the result. NSError *error = nil; NSMutableArray *mutableFetchResults = [[managedObjectContext executeFetchRequest:request error:&error] mutableCopy]; if (mutableFetchResults == nil) { // Handle the error. } LocationsAppDelegate *mainDelegate = (LocationsAppDelegate *)[[UIApplication sharedApplication] delegate]; // Set master albums array to the mutable array, then clean up. [mainDelegate setAlbumsArray:mutableFetchResults]; [mutableFetchResults release]; [request release]; } But when I run similar code inside viewdidappear, nothing happens: { /* Fetch existing albums. Create a fetch request; find the Album entity and assign it to the request; add a sort descriptor; then execute the fetch. */ NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Album" inManagedObjectContext:managedObjectContext]; [request setEntity:entity]; // Order the albums by creation date, most recent first. NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"albumName" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [sortDescriptor release]; [sortDescriptors release]; // Execute the fetch -- create a mutable copy of the result. NSError *error = nil; NSMutableArray *mutableFetchResults = [[managedObjectContext executeFetchRequest:request error:&error] mutableCopy]; if (mutableFetchResults == nil) { // Handle the error. } LocationsAppDelegate *mainDelegate = (LocationsAppDelegate *)[[UIApplication sharedApplication] delegate]; // Set master albums array to the mutable array, then clean up. [mainDelegate setAlbumsArray:mutableFetchResults]; [self.tableView reloadData]; [mutableFetchResults release]; [request release]; } Apologies if I've missed the answer to this question elsewhere, but what am I missing?

• making an array controller the target of a button

• All UITableCells rendered at once... why?

  - by Greg

  I'm extremely confused by the proper behavior of UITableView cell rendering. Here's the situation: I have a list of 250 items that are loading into a table view, each with an image. To optimize the image download, I followed along with Apple's LazyTableImages sample code... pretty much following it exactly. Really good system... for reference, here's the cell renderer within the Apple sample code: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // customize the appearance of table view cells // static NSString *CellIdentifier = @"LazyTableCell"; static NSString *PlaceholderCellIdentifier = @"PlaceholderCell"; // add a placeholder cell while waiting on table data int nodeCount = [self.entries count]; if (nodeCount == 0 && indexPath.row == 0) { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:PlaceholderCellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:PlaceholderCellIdentifier] autorelease]; cell.detailTextLabel.textAlignment = UITextAlignmentCenter; cell.selectionStyle = UITableViewCellSelectionStyleNone; } cell.detailTextLabel.text = @"Loading…"; return cell; } UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease]; cell.selectionStyle = UITableViewCellSelectionStyleNone; } // Leave cells empty if there's no data yet if (nodeCount > 0) { // Set up the cell... AppRecord *appRecord = [self.entries objectAtIndex:indexPath.row]; cell.textLabel.text = appRecord.appName; cell.detailTextLabel.text = appRecord.artist; // Only load cached images; defer new downloads until scrolling ends if (!appRecord.appIcon) { if (self.tableView.dragging == NO && self.tableView.decelerating == NO) { [self startIconDownload:appRecord forIndexPath:indexPath]; } // if a download is deferred or in progress, return a placeholder image cell.imageView.image = [UIImage imageNamed:@"Placeholder.png"]; } else { cell.imageView.image = appRecord.appIcon; } } return cell; } So – my implementation of Apple's LazyTableImages system has one crucial flaw: it starts all downloads for all images immediately. Now, if I remove this line: //[self startIconDownload:appRecord forIndexPath:indexPath]; Then the system behaves exactly like you would expect: new images load as their placeholders scroll into view. However, the initial view cells do not automatically load their images without that prompt in the cell renderer. So, I have a problem: with the prompt in the cell renderer, all images load at once. Without the prompt, the initial view doesn't load. Now, this works fine in Apple sample code, which got me wondering what was going on with mine. It's almost like it was building all cells up front rather than just the 8 or so that would appear within the display. So, I got looking into it, and this is indeed the case... my table is building 250 unique cells! I didn't think the UITableView worked like this, I guess I thought it only built as many items as were needed to populate the table. Is this the case, or is it correct that it would build all 250 cells up front? Also – related question: I've tried to compare my implementation against the Apple LazyTableImages sample, but have discovered that NSLog appears to be disabled within the Apple sample code (which makes direct behavior comparisons extremely difficult). Is that just a simple publish setting somewhere, or has Apple somehow locked down their samples so that you can't log output at runtime? Thanks!

• "didChangeSection:" NSfetchedResultsController delegate method not being called

  - by robenk

  I have a standard split view controller, with a detail view and a table view. Pressing a button in the detail view can cause the an object to change its placement in the table view's ordering. This works fine, as long as the resulting ordering change doesn't result in a section being added or removed. I.e. an object can change it's ordering in a section or switch from one section to another. Those ordering changes work correctly without problems. But, if the object tries to move to a section that doesn't exist yet, or is the last object to leave a section (therefore requiring the section its leaving to be removed), then the application crashes. NSFetchedResultsControllerDelegate has methods to handle sections being added and removed that should be called in those cases. But those delegate methods aren't being called for some reason. The code in question, is boilerplate: - (void)controllerWillChangeContent:(NSFetchedResultsController *)controller { NSLog(@"willChangeContent"); [self.tableView beginUpdates]; } - (void)controller:(NSFetchedResultsController *)controller didChangeSection:(id <NSFetchedResultsSectionInfo>)sectionInfo atIndex:(NSUInteger)sectionIndex forChangeType:(NSFetchedResultsChangeType)type { NSLog(@"didChangeSection"); switch(type) { case NSFetchedResultsChangeInsert: [self.tableView insertSections:[NSIndexSet indexSetWithIndex:sectionIndex] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [self.tableView deleteSections:[NSIndexSet indexSetWithIndex:sectionIndex] withRowAnimation:UITableViewRowAnimationFade]; break; } } - (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath { NSLog(@"didChangeObject"); UITableView *tableView = self.tableView; switch(type) { case NSFetchedResultsChangeInsert: [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeUpdate: [self configureCell:[tableView cellForRowAtIndexPath:indexPath] atIndexPath:indexPath]; break; case NSFetchedResultsChangeMove: [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath]withRowAnimation:UITableViewRowAnimationFade]; break; } } - (void)controllerDidChangeContent:(NSFetchedResultsController *)controller { NSLog(@"didChangeContent"); [self.tableView endUpdates]; [detailViewController.reminderView update]; } Starting the application, and then causing the last object to leave a section results in the following output: 2011-01-08 23:40:18.910 Reminders[54647:207] willChangeContent 2011-01-08 23:40:18.912 Reminders[54647:207] didChangeObject 2011-01-08 23:40:18.914 Reminders[54647:207] didChangeContent 2011-01-08 23:40:18.915 Reminders[54647:207] *** Assertion failure in -[UITableView _endCellAnimationsWithContext:], /SourceCache/UIKit_Sim/UIKit-1145.66/UITableView.m:825 2011-01-08 23:40:18.917 Reminders[54647:207] Serious application error. Exception was caught during Core Data change processing: Invalid update: invalid number of sections. The number of sections contained in the table view after the update (5) must be equal to the number of sections contained in the table view before the update (6), plus or minus the number of sections inserted or deleted (0 inserted, 0 deleted). with userInfo (null) As you can see, "willChangeContent", "didChangeObject" (moving the object in question), and "didChangeContent" were all called properly. Based on the Apple's NSFetchedResultsControllerDelegate documentation "didChangeSection" should have been called before "didChangeObject", which would have prevented the exception causing the crash. So I guess the question is how do I assure that didChangeSection gets called? Thanks in advance for any help!
