• Is use of LEAKS instrument still common on 3G iPhone?

  - by gordonmcdowell

  I'm working with an iPhone 3G, and when I'm trying to investigate memory leaks using the LEAKS instrument, my app crashes. It does not crash when LEAKS is not used. I'm making no claim to having a bug-free or non-memory-intensive app here. But I'd like to investigate leaks on an actual device. When I'm running LEAKS it is incredibly slow. Are there still developers working on iPhone 3G? I don't want to be the whiny guy blaming his tools, but I'd also like to be sure the whole dev world hasn't moved on to iPhone 3GS and I'm the only one trying to run both my app and leaks on a 3G. Currently running iOS 4.0 "gold". Snow Leopard dev env with latest XCode.

• Can my app arrange a gdb breakpoint or watch?

  - by Larry Gritz

  Is there a way for my code to be instrumented to insert a break point or watch on a memory location that will be honored by gdb? (And presumably have no effect when gdb is not attached.) I know how to do such things as gdb commands within the gdb session, but for certain types of debugging it would be really handy to do it "programmatically", if you know what I mean -- for example, the bug only happens with a particular circumstance, not any of the first 11,024 times the crashing routine is called, or the first 43,028,503 times that memory location is modified, so setting a simple break point on the routine or watch point on the variable is not helpful -- it's all false positives. I'm concerned mostly about Linux, but curious about if similar solutions exist for OS X (or Windows, though obviously not with gdb).

• How do I store in subversion my customizations to a public open source project?

  - by Clyde

  Hi, I'm working on customizing a couple of open source projects in ways that are very much personalized -- i.e., not appropriate to send the patches back to the maintainers for the public. One of them is stored in CVS, one in SVN. I use SVN for my own work. The CVS project is fine. I check the tree in to my svn repository, including the CVS directories. I can commit all my changes, and still do a cvs update to stay up to date with bug fixes/features of the public project. How should I work on the svn project? Is there a 'best practice' or known procedure for this kind of scenario?

• Touch event missing when pushing new view

  - by Milu

  Hello, I am new in iPhone programming. At the moment I am trying to recognize a constant touch. For example I want the user to leave his finger on the screen for the whole application. I use a navigationcontroller which holds the different views. If the user now touches the screen in view1 and then the view is changed to view2 by pushing it on the stack (with pushviewcontroller) with still touching the screen then there are no touch events recognized by view2. If the user then releases his finger (no touch event) and touches the screen again then all events are recognized. Is this a bug or am I doing something totally wrong? I haven't found any answer on this. Could someone help me?

• ChoiceFormat.setChoices confusion about format parameter type and documentation

  - by polygenelubricants

  From the java.text.ChoiceFormat API: setChoices(double[] limits, String[] formats): Set the choices to be used in formatting. Parameters: limits - contains [...] formats - are the formats you want to use for each limit. They can be either Format objects or Strings. When formatting with object Y, if the object is a NumberFormat, then ((NumberFormat) Y).format(X) is called. Otherwise Y.toString() is called. I'm having difficulties understanding the documentation for the formats parameter: how can you possibly pass a Format/NumberFormat object to setChoices if it's declared String[] formats? Note that interestingly, the getters counterpart of setChoices are declared as follows: double[] getLimits() Object[] getFormats() -- not String[]!!! Is this a bug in the API? Should the setter have been declared setChoices(double[], Object[]) instead, or am I not understanding how to use setChoices correctly?

• RelativeLayout - positioning a View under a ViewGroup

  - by Richard

  I have the following structure defined in an xml layout file. <RelativeLayout android:id="@+id/mainLayout" xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> <FrameLayout android:id="@+id/frame" android:layout_centerInParent="true" android:layout_width="wrap_content" android:layout_height="wrap_content" ></FrameLayout> <Button android:id="@+id/button" android:layout_below="@id/frame" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </RelativeLayout> The FrameLayout is positioned correctly in the center of its parent. But the Button isn't getting positioned under it. Instead it's displaying in the top left corner. Am I doing something incorrectly or is this a bug with RelativeLayout?

• Is there a browser-agnostic way to detect client-side script errors with Watin?

  - by Michael

  We're using WatiN to test our web portals. During the course of an E2E test, we'll occasionally see client-side script errors on the IE status bar. I'd like to chain a handler onto the script error event and record the error for later analysis and bug filing. Problem is, I don't know that there's a global script error event or how to chain into it. And if there's not a browser-agnostic way to accomplish this, I can create MyIE and MyFF subclasses but then this becomes two browser-specific questions. In essence, I'm thinking of something like this entirely made-up call: browser.ScriptEngine.SetCustomErrorHandler(LogScriptingError); ... where LogScriptErrors is my code that does the obvious. Many of our client-side scripting errors don't necessarily prevent the test from continuing (a pretty UI element didn't animate, for example, but the underlying form is still submittable), so I'd like to log the error and forge ahead in most cases.

• Why are all my masked views unmasked in my view snapshot?

  - by mystify

  I'm taking a snapshot of an view. This view has got some subviews which have layer masks applied to them. For some reason, those masks take no effect in the snapshot and the masked parts are completely visible. UIGraphicsBeginImageContext(theView.frame.size); [theView.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); I assume this is a bug in the framework. But maybe it's not? Did I do anything wrong here?

• NSDateFormatter iOS6 issue

  - by Angad Manchanda

  I have written a code for UIButton press to decrement date. The present date is shown in a UILabel text property and it changes to the previous date when the button is pressed. The following code works perfectly fine for iOS5 but doesn't work with iOS6. With iOS6, it gives the output as Dec 31, 1999 or null. - (IBAction)showPrevDate:(id)sender { NSString *dateForDecrement = _showDateLbl.text; [dateFormatter setDateFormat:@"MMM d, yyyy (EEE)"]; NSDate *dateObjectForDecrement = [dateFormatter dateFromString:dateForDecrement]; int subtractDays = 1; dateAfterDecrement=[dateObjectForDecrement dateByAddingTimeInterval:-(24*60*60 * subtractDays)]; _showDateLbl.text = [NSString stringWithFormat:@"%@", [dateFormatter stringFromDate:dateAfterDecrement]]; } Can anybody verify this, or tell me if its's a bug in iOS6 ? Thanks guys.

• IE 8 specifying background-color changes element behavior

  - by Mateo

  I have an absolutely positioned div on which I am trying to trigger mouseenter and mouseleave events. In IE8/7 with the background-color of the div left unspecified (so that it defaults to transparent), the mouseenter/leave events are not firing when the cursor crosses the div's boundary, only somewhere in the middle of the div and when the cursor is over any text within the div. When I attempt to debug the problem by adding a background color to the div (e.g. background-color: green), the problem magically goes away. The div's box model is honored perfectly and mouseenter/leave fire as when expected. It's only when the div's background color is left unspecified (or even explicitly set to transparent) that it doesn't behave correctly. Any ideas? Googling for this IE bug/quirk is coming up with nothing.

• Website renders two scroll bars, is it the CSS, xhtml, or some jquery plugin?

  - by Muhammad

  I've come to notice a bug on my website, I see that there's two scroll bars when the window is re-sized from a full sized window (my desktop's 1280x900). This issue is untraceable with Firebug and it shows up on all browsers. I'm using a JQuery UI script on the page as well but I'm not sure if that's what's doing this. What's a good way to go about getting rid of this? Or has anyone ever encountered having two scroll bars on the page? BTW: The in-page scroll bar is actually above the footer, if that helps.

• UISwitch text not showing on device

  - by iFloh

  Hi, I have a screen with several UISwitch controls. On my iPhone simulator this screen works correctly and The Switch text shows as On/Off. Different on my testing device (iPod Touch). Here the text seems to get lost and I only get "1" (instead of "On") and "0" (instead of "Off"). I don't know where the iPod Touch is different and why it's not showing correctly. Anyone had a similar experience? Is this a bug? Cheers

• Webkit browsers rendering CSS different than Mozilla Firefox...Why??

  - by JAG2007

  I'm styling a form that was already marked up (made some markup changes), and I normally work in Firefox to style so I can use firebug and the web developer toolbar. On this project, I noticed that my styles are displaying quite differently for one particular area (several elements) in webkit based browsers Chrome and Safari, than in Firefox (we won't even get into Internet Explorer, although it is siding with the Firefox display). I can't figure out though why the styles are displaying so differently. Normally there is some rule that I'm neglecting that Firefox just takes for granted, and the others need it specified. But here I'm not getting why it's displaying this way. In particular I'm referring to the bottom area of the form where users can enter their contact info, then submit the form. I'll attach screen shots for reference as to the discrepancy. Here's the URL so feel free to check it out on your own. Although be advised that this is a production page (already released) so if you try out the form, you WILL BE added to CURE's contact database. http://www.helpcurenow.org/survey2010 Here's the screen shots: Firefox (the way I intend it to look) Chrome, and then Safari - strange change to submit button As a bonus, if anybody wants to help me with figuring out why on earth IE7 wants to not show the background behind the questions only, and how to fix that I would be much obliged! Thanks very much.

• Weblogic server lib VS instance libext

  - by Sebastien Lorber

  Hello, I use weblogic 10. Its provide an Oracle JDBC driver 10.2.0.2 (in the server/lib on weblogic home). Actually someone at work put a long time ago a 10.2.0.3 driver in instance libext folder. But in production we got a jdbc driver stack (nullpointer :O) and by reverse engineering it seems we are using driver 10.2.0.2. We know that we could change the driver in the server/lib of weblogic but i want to understand. Isn't libext supposed to override server libs like META-INF libs override libext? By the way we are in a strange situation: - We have 2 EAR, and for the exact same treatment in those 2, one will sometime throw the oracle driver nullpointer while the other doesn't - I wonder if one ear isn't using 10.2.0.2 while the other is using 10.2.0.3 (i saw a bug fixed that could fit to our problem for this version). - I need to look better but at first sight both ear use the exact same datasource set in weblogic JNDI resources Any idea?

• FindBugs and CheckForNull on classes vs. interfaces

  - by ndn

  Is there any way to let FindBugs check and warn me if a CheckForNull annotation is present on the implementation of a method in a class, but not on the declaration of the method in the interface? import javax.annotation.CheckForNull; interface Foo { public String getBar(); } class FooImpl implements Foo { @CheckForNull @Override public String getBar() { return null; } } public class FindBugsDemo { public static void main(String[] args) { Foo foo = new FooImpl(); System.out.println(foo.getBar().length()); } } I just discovered a bug in my application due to a missing null check that was not spotted by FindBugs because CheckForNull was only present on FooImpl, but not on Foo, and I don't want to spot all other locations of this problem manually.

• MySQL enters another value that the one given by PHP

  - by Tristan

  Hello, The big problem : mysql does not stores the information i told him to via PHP Example (this req is an echo just before the query) : INSERT INTO serveur (GSP_nom , IPserv, port, tickrate, membre, nomPays, finContrat, type, jeux, slot, ipClient, email) VALUES ( 'ckras', '88.191.88.57', '37060', '100' , '', 'Allemagne','20110519', '2', '4','99' ,'82.220.201.183','[email protected]'); But on the MySQL i have : 403 ckras 88.191.88.57 32767 100 Allemagne 20110519 1 2010-04-25 00:51:47 2 4 99 82.220.201.183 [email protected] port : 37060 (right value) //// 32767 (MySQL's drug?) Any help would be appreciated, i'm worse than stuck and i'm ** off PS: *There is no trigger on the mysql as far as i know / there is no controll on the port which means that nowhere i modify the "port" value and this script works for 80% of the time ( it seems that as soon as the users enters a port = 30000 it causes that bug), an user first reported to me this error today and the script was running since 3 months* Thanks

• Sending a 'copy' command in cocoa

  - by Ben Packard

  Is there any way to send a copy (command-c) instruction without using a cgEvent to mimic the keystrokes? I don't have access to the text field in the application I want to take text from, so need to replicate manually copying to the clipboard, and there seemss to be a bug with cgevent posting. According the Quartz documentation, to type a capital Z I should use: CGEventRef event1, event2, event3, event4; event1 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)56, true); event2 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)6, true); event3 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)6, false); event4 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)56, false); However, if I attach this set of instuctions to an NSTimer, it only works the first time it is fired. example output: ZzzZzzzzZZzzZ (vs expected ZZZZZZZZZ). How else might I send a copy command to the active window?

• Div at bottom of window and adaptable height div

  - by Rob

  Is there a way to get a div to always be at the bottom of the window, and another div to change its height to fill any space that it leaves, and that div will scroll if its content is too long. (I never want the window to scroll). This is best illustrated by a picture: The green div will always put itself at the bottom of the window, and the orange div will fill the gap. When the window is smaller, like in the right hand image, the orange div will be smaller and will scroll. The green div can be toggled. Sometimes the green div will have display: none, and then the orange div will stretch to the bottom. When the green div has display: block again, it will look like the picture again. It has to work in IE6. So far I can get the green div to go to the bottom by: position: absolute; bottom: 0; But I don't know how to get the orange div to do what I want.

• Export Multiple Sheets to Excel Through Browser

  - by ProfK

  I need to export multiple data tables to Excel on the clients machine, each to their own sheet. If it was just one sheet, I'd use the Excel/csv content type, but I've heard something about an XML format that can represent an entire workbook. I don't want to go down the Packaging and .xlsx route, so I need standard .xls. Our bug tracker, Gemini, used to have an export function that produced an XML file that Excel automatically opened as a multi-sheet workbook, but I can't find it. Is there still such a mechanism, and where can I find that schema?

• Good Silverlight 4.0 chart / graph component?

  - by Duncan Bayne

  I've been using the Silverlight Toolkit but I'm finding the quality lacking; in particular this memory leak / phantom point bug renders the Chart component completely unusable. Can anyone recommend a good chart / graph component for Silverlight 4.0? I'm looking for one that provides: multiple simultaneous series, both scatter and line multi-select of points configurable tool-tips automatic axis scaling real-time update of data That last point sounds trivial but is tripping up the Silverlight Toolkit Chart; if you rapidly change the axis range, it sometimes leaves phantom points behind in addition to the points it should be displaying.

• Parantheses around method invokation: why is the compiler complaining about assignment?

  - by polygenelubricants

  I know why the following code doesn't compile: public class Main { public static void main(String args[]) { main((null)); // this is fine! (main(null)); // this is NOT! } } What I'm wondering is why my compiler (javac 1.6.0_17, Windows version) is complaining "The left hand side of an assignment must be a variable". I'd expect something like "Don't put parantheses around a method invokation, dummy!", instead. So why is the compiler making a totally unhelpful complaint about something that is blatantly irrelevant? Is this the result of an ambiguity in the grammar? A bug in the compiler? If it's the former, could you design a language such that a compiler would never be so off-base about a syntax error like this?

• asterisk public ip and clients with public / private ip

  I am using asterisk with a public ip. I have 4 clients which could be behind a nat or with public ip. I did set for all the clients nat=yes and canreinvite=no and qualify=yes. I did notice that if the clients were behind the nat everything went ok, but if the clients had public the call did not establish (no ringing on the asterisk server). WHere is the problem? Is there a bug in asterisk? As I've no there should be no problem for public ip and server with public ip.
