  • Nullpointerexcption & abrupt IOStream closure with inheritence and subclasses

    - by user1401652
    A brief background before so we can communicate on the same wave length. I've had about 8-10 university courses on programming from data structure, to one on all languages, to specific ones such as java & c++. I'm a bit rusty because i usually take 2-3 month breaks from coding. This is a personal project that I started thinking of two years back. Okay down to the details, and a specific question, I'm having problems with my mutator functions. It seems to be that I am trying to access a private variable incorrectly. The question is, am I nesting my classes too much and trying to mutate a base class variable the incorrect way. If so point me in the way of the correct literature, or confirm this is my problem so I can restudy this information. Thanks package GroceryReceiptProgram; import java.io.*; import java.util.Vector; public class Date { private int hour, minute, day, month, year; Date() { try { BufferedReader keyboard = new BufferedReader(new InputStreamReader(System.in)); System.out.println("What's the hour?

  • Translate Basic Config.groovy log4j DSL to external log4j.properties

    - by Stephen Swensen
    The following is a basic log4j configuration inside Config.groovy using the log4j DSL with Grails 1.2, it works as expected (log all errors to the given file): log4j = { appenders { file name:'file', file:"c:/error.log" } error 'grails.app' root { error 'file' } } How would one translate this into a properties style log4j configuration file? The following does not work: log4j.rootLogger=ERROR, FA log4j.appender.FA=org.apache.log4j.FileAppender log4j.appender.FA.File=C:/error.log log4j.logger.grails.app=ERROR, FA I suspect it has something to do with the translation of error 'grails.app' but I really don't know. If it makes any difference, the properties file is configured externally: grails.config.locations = ["file:${basedir}/extconf/log4j.properties"] All I really want is an external log4j properties file which logs all application exceptions to a file.

  • Regression testing with Selenium GRID

    - by Ben Adderson
    A lot of software teams out there are tasked with supporting and maintaining systems that have grown organically over time, and the web team here at Red Gate is no exception. We're about to embark on our first significant refactoring endeavour for some time, and as such its clearly paramount that the code be tested thoroughly for regressions. Unfortunately we currently find ourselves with a codebase that isn't very testable - the three layers (database, business logic and UI) are currently tightly coupled. This leaves us with the unfortunate problem that, in order to confidently refactor the code, we need unit tests. But in order to write unit tests, we need to refactor the code :S To try and ease the initial pain of decoupling these layers, I've been looking into the idea of using UI automation to provide a sort of system-level regression test suite. The idea being that these tests can help us identify regressions whilst we work towards a more testable codebase, at which point the more traditional combination of unit and integration tests can take over. Ending up with a strong battery of UI tests is also a nice bonus :) Following on from my previous posts (here, here and here) I knew I wanted to use Selenium. I also figured that this would be a good excuse to put my xUnit [Browser] attribute to good use. Pretty quickly, I had a raft of tests that looked like the following (this particular example uses Reflector Pro). In a nut shell the test traverses our shopping cart and, for a particular combination of number of users and months of support, checks that the price calculations all come up with the correct values. [BrowserTheory] [Browser(Browsers.Firefox3_6, "http://www.red-gate.com")] public void Purchase1UserLicenceNoSupport(SeleniumProvider seleniumProvider) {     //Arrange     _browser = seleniumProvider.GetBrowser();     _browser.Open("http://www.red-gate.com/dynamic/shoppingCart/ProductOption.aspx?Product=ReflectorPro");                  //Act     _browser = ShoppingCartHelpers.TraverseShoppingCart(_browser, 1, 0, ".NET Reflector Pro");     //Assert     var priceResult = PriceHelpers.GetNewPurchasePrice(db, "ReflectorPro", 1, 0, Currencies.Euros);         Assert.Equal(priceResult.Price, _browser.GetText("ctl00_content_InvoiceShoppingItemRepeater_ctl01_Price"));     Assert.Equal(priceResult.Tax, _browser.GetText("ctl00_content_InvoiceShoppingItemRepeater_ctl02_Tax"));     Assert.Equal(priceResult.Total, _browser.GetText("ctl00_content_InvoiceShoppingItemRepeater_ctl02_Total")); } These tests are pretty concise, with much of the common code in the TraverseShoppingCart() and GetNewPurchasePrice() methods. The (inevitable) problem arose when it came to execute these tests en masse. Selenium is a very slick tool, but it can't mask the fact that UI automation is very slow. To give you an idea, the set of cases that covers all of our products, for all combinations of users and support, came to 372 tests (for now only considering purchases in dollars). In the world of automated integration tests, that's a very manageable number. For unit tests, it's a trifle. However for UI automation, those 372 tests were taking just over two hours to run. Two hours may not sound like a lot, but those cases only cover one of the three currencies we deal with, and only one of the many different ways our systems can be asked to calculate a price. It was already pretty clear at this point that in order for this approach to be viable, I was going to have to find a way to speed things up. Up to this point I had been using Selenium Remote Control to automate Firefox, as this was the approach I had used previously and it had worked well. Fortunately,  the guys at SeleniumHQ also maintain a tool for executing multiple Selenium RC tests in parallel: Selenium Grid. Selenium Grid uses a central 'hub' to handle allocation of Selenium tests to individual RCs. The Remote Controls simply register themselves with the hub when they start, and then wait to be assigned work. The (for me) really clever part is that, as far as the client driver library is concerned, the grid hub looks exactly the same as a vanilla remote control. To create a new browser session against Selenium RC, the following C# code suffices: new DefaultSelenium("localhost", 4444, "*firefox", "http://www.red-gate.com"); This assumes that the RC is running on the local machine, and is listening on port 4444 (the default). Assuming the hub is running on your local machine, then to create a browser session in Selenium Grid, via the hub rather than directly against the control, the code is exactly the same! Behind the scenes, the hub will take this request and hand it off to one of the registered RCs that provides the "*firefox" execution environment. It will then pass all communications back and forth between the test runner and the remote control transparently. This makes running existing RC tests on a Selenium Grid a piece of cake, as the developers intended. For a more detailed description of exactly how Selenium Grid works, see this page. Once I had a test environment capable of running multiple tests in parallel, I needed a test runner capable of doing the same. Unfortunately, this does not currently exist for xUnit (boo!). MbUnit on the other hand, has the concept of concurrent execution baked right into the framework. So after swapping out my assembly references, and fixing up the resulting mismatches in assertions, my example test now looks like this: [Test] public void Purchase1UserLicenceNoSupport() {    //Arrange    ISelenium browser = BrowserHelpers.GetBrowser();    var db = DbHelpers.GetWebsiteDBDataContext();    browser.Start();    browser.Open("http://www.red-gate.com/dynamic/shoppingCart/ProductOption.aspx?Product=ReflectorPro");                 //Act     browser = ShoppingCartHelpers.TraverseShoppingCart(browser, 1, 0, ".NET Reflector Pro");    var priceResult = PriceHelpers.GetNewPurchasePrice(db, "ReflectorPro", 1, 0, Currencies.Euros);    //Assert     Assert.AreEqual(priceResult.Price, browser.GetText("ctl00_content_InvoiceShoppingItemRepeater_ctl01_Price"));     Assert.AreEqual(priceResult.Tax, browser.GetText("ctl00_content_InvoiceShoppingItemRepeater_ctl02_Tax"));     Assert.AreEqual(priceResult.Total, browser.GetText("ctl00_content_InvoiceShoppingItemRepeater_ctl02_Total")); } This is pretty much the same as the xUnit version. The exceptions are that the attributes have changed,  the //Arrange phase now has to handle setting up the ISelenium object, as the attribute that previously did this has gone away, and the test now sets up its own database connection. Previously I was using a shared database connection, but this approach becomes more complicated when tests are being executed concurrently. To avoid complexity each test has its own connection, which it is responsible for closing. For the sake of readability, I snipped out the code that closes the browser session and the db connection at the end of the test. With all that done, there was only one more step required before the tests would execute concurrently. It is necessary to tell the test runner which tests are eligible to run in parallel, via the [Parallelizable] attribute. This can be done at the test, fixture or assembly level. Since I wanted to run all tests concurrently, I marked mine at the assembly level in the AssemblyInfo.cs using the following: [assembly: DegreeOfParallelism(3)] [assembly: Parallelizable(TestScope.All)] The second attribute marks all tests in the assembly as [Parallelizable], whilst the first tells the test runner how many concurrent threads to use when executing the tests. I set mine to three since I was using 3 RCs in separate VMs. With everything now in place, I fired up the Icarus* test runner that comes with MbUnit. Executing my 372 tests three at a time instead of one at a time reduced the running time from 2 hours 10 minutes, to 55 minutes, that's an improvement of about 58%! I'd like to have seen an improvement of 66%, but I can understand that either inefficiencies in the hub code, my test environment or the test runner code (or some combination of all three most likely) contributes to a slightly diminished improvement. That said, I'd love to hear about any experience you have in upping this efficiency. Ultimately though, it was a saving that was most definitely worth having. It makes regression testing via UI automation a far more plausible prospect. The other obvious point to make is that this approach scales far better than executing tests serially. So if ever we need to improve performance, we just register additional RC's with the hub, and up the DegreeOfParallelism. *This was just my personal preference for a GUI runner. The MbUnit/Gallio installer also provides a command line runner, a TestDriven.net runner, and a Resharper 4.5 runner. For now at least, Resharper 5 isn't supported.

  • How do I aggregate results from an Adjacency list using PHP's SPL

    - by Stephen J. Fuhry
    I've tried using nested sets, and they become very difficult to maintain when dealing with multiple trees and lots of other complications.. I'd like to give PHP's SPL library a stab at this (btw, we are PHP 5.3, MySQL 5.1). Given two datasets: The Groups: +-------+--------+---------------------+---------------+ | id | parent | Category Name | child_key | +-------+--------+---------------------+---------------+ | 11133 | 7707 | Really Cool Products| 47054 | | 7709 | 7708 | 24" Monitors | 57910 | | 7713 | 7710 | Hot Tubs | 35585 | | 7716 | 7710 | Hot Dogs | 00395 | | 11133 | 7707 | Really Cool Products| 66647 | | 7715 | 7710 | Suction Cups | 08396 | +-------+--------+---------------------+---------------+ The Items +------------+------------+-----------+----------+---------+ | child_key | totalprice | totalcost | totalqty | onorder | (jan, feb, mar..) +------------+------------+-----------+----------+---------+ | 24171 | 10.50 | 20.10 | 200 | 100 | | 35685 | 10.50 | 20.10 | 200 | 100 | | 76505 | 10.50 | 20.10 | 200 | 100 | | 04365 | 10.50 | 20.10 | 200 | 100 | | 01975 | 10.50 | 20.10 | 200 | 100 | | 12150 | 10.50 | 20.10 | 200 | 100 | | 40060 | 10.50 | 20.10 | 200 | 100 | | 08396 | 10.50 | 20.10 | 200 | 100 | +------------+------------+-----------+----------+---------+ The figures are actually much more complicated than this (I am actually aggregating a variable amount of months or years over the past 15yrs, so there may need to be 20 columns of aggregated results). I have been trying to figure out RecursiveIterator and IteratorAggregate, but I am having a difficult time finding real world examples that are generic enough to really wrap my head around these classes. Can someone give me a head start?

  • What is the difference between DVCS systems?

    - by Stephen
    What is the difference between DVCS systems? Seriously, wikipedia doesn't cover it well, and I read an article on HN recently comparing git and bzr in some detail, but the author admitted knowing little about mercurial, and the other options didn't get mentioned. (I'm happily using fossil on small win/mac/Linux projects) Please restrict answers to the DVCS aspects of the tool, e.g. The basic unit of vc in hit is the repository- in bazaar it is the branch(http://unspecified.wordpress.com/2010/03/26/why-git-aint-better-than-x/). bugtrackers and wikis are nice, but I'm really interested in the tools themselves, rather than any extras. Unfortunately SO demands a single 'right answer', so I'm making the question community wiki in the hope that users will contribute their knowledge.

  • Editing a UITextField inside a UITableViewCell fails

    - by Stephen Darlington
    In my application I have a UITextField inside a UITableViewCell. If I click inside the text field and add some text I find that if try to move the insertion point it works the first time but fails on subsequent attempts. I am completely unable to move the selection; no "magnifying glass" appears. Even more curious, this "setting" seems to be permanent until I restart the application. And it affects all UITextFields on that screen and not just the one that I originally tried to edit. If you want to see it yourself, try the "UICatalog" sample that comes with the iPhone SDK. Click "text fields" and then "edit" and play around with the text boxes. I've done a lot of digging on this but it's pretty hard to Google for! The best references I've found are on Apple's support board and MacRumors formum (both reference a solution that apparently used to work on iPhone 2.0 but does work not with contemporary versions -- I did try). My feeling that is that this is a bug in the OS, but I thought I'd throw this out to the SO crowd for a second opinion and to see if there are any workarounds. Any ideas? Following benzado's suggestion, I tried building my application using the 2.0, 2.1 and 2.2 SDKs. I got the same behaviour in all versions. (Actually, something related but not the same broke in 2.2 but that's probably another question!)

  • How to get rank from full-text search query with Linq to SQL?

    - by Stephen Jennings
    I am using Linq to SQL to call a stored procedure which runs a full-text search and returns the rank plus a few specific columns from the table Article. The rank column is the rank returned from the SQL function FREETEXTTABLE(). I've added this sproc to the data model designer with return type Article. This is working to get the columns I need; however, it discards the ranking of each search result. I'd like to get this information so I can display it to the user. So far, I've tried creating a new class RankedArticle which inherits from Article and adds the column Rank, then changing the return type of my sproc mapping to RankedArticle. When I try this, an InvalidOperationException gets thrown: Data member 'Int32 ArticleID' of type 'Heap.Models.Article' is not part of the mapping for type 'RankedArticle'. Is the member above the root of an inheritance hierarchy? I can't seem to find any other questions or Google results from people trying to get the rank column, so I'm probably missing something obvious here.

  • NSURL URLWithString: raises exception

    - by Stephen Darlington
    In short, [NSURL URLWithString:] appears to be raising an exception. According to the documentation "If the string was malformed, returns nil." There is no mention of an exception being raised under any circumstance. In addition to this, I am both encoding the URL and checking for nil before converting the string to a URL. Can anyone offer any advice as to which exception it could be or what other error checking I should be doing before converting the URL? In case you're interested in the details, the calling code looks like this: NSString* tmpText = [newUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; if (tmpText == nil) { // error handling } else { NSURL* tmpURL = [NSURL URLWithString:tmpText]; And this is a section from the crash report download from iTunes Connect: 8 libobjc.A.dylib 0x300c1f84 objc_exception_throw 9 CoreFoundation 0x3029a598 +[NSException raise:format:arguments:] 10 CoreFoundation 0x3029a538 +[NSException raise:format:] 11 Foundation 0x30696dde -[NSURL initWithString:relativeToURL:] 12 Foundation 0x30696cd8 +[NSURL URLWithString:relativeToURL:] 13 Foundation 0x30696cae +[NSURL URLWithString:] 14 Yummy 0x000146ca -[DeliciousPostCell setUrl:] + 46 It seems that the URL was in a "bad" format somehow but that should really be returning a nil not an exception. I have never seen the exception being raised myself so I can't use XCode to trap the code and see what's happening. And the user(s) that experienced the problem never contacted me directly so I can't ask for more details. Any suggestions greatly appreciated. Update (14/7/2009): Seems like such a hack, but I added an exception block around the suspect line. I also raised a Radar bug report (#7031551) suggesting that the code should match the documentation.

  • Is it possible to programmatically set the state of the shift and control keys?

    - by Stephen Harrison
    The reason I am asking is that I am thinking of building a foot switch to act as shift and control keys - well two switches, one for each foot. I'm planning on using the Arduino for this and writing a small C# application to detect when the switch has been pressed that would then set the state of shift or control. I would rather not have to write a keyboard driver for the Arduino as I would like it to do other things as well.

  • w3schools xsd example won't work with dom4j. How do I use dom4j to validate xml using xsds?

    - by HappyEngineer
    I am trying to use dom4j to validate the xml at http://www.w3schools.com/Schema/schema_example.asp using the xsd from that same page. It fails with the following error: org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'shiporder'. I'm using the following code: SAXReader reader = new SAXReader(); reader.setValidation(true); reader.setFeature("http://apache.org/xml/features/validation/schema", true); reader.setErrorHandler(new XmlErrorHandler()); reader.read(in); where in is an InputStream and XmlErrorHandler is a simple class that just logs all errors. I'm using the following xml file: <?xml version="1.0" encoding="ISO-8859-1"?> <shiporder orderid="889923" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="test1.xsd"> <orderperson>John Smith</orderperson> <shipto> <name>Ola Nordmann</name> <address>Langgt 23</address> <city>4000 Stavanger</city> <country>Norway</country> </shipto> <item> <title>Empire Burlesque</title> <note>Special Edition</note> <quantity>1</quantity> <price>10.90</price> </item> <item> <title>Hide your heart</title> <quantity>1</quantity> <price>9.90</price> </item> </shiporder> and the corresponding xsd: <?xml version="1.0" encoding="ISO-8859-1" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:simpleType name="stringtype"> <xs:restriction base="xs:string"/> </xs:simpleType> <xs:simpleType name="inttype"> <xs:restriction base="xs:positiveInteger"/> </xs:simpleType> <xs:simpleType name="dectype"> <xs:restriction base="xs:decimal"/> </xs:simpleType> <xs:simpleType name="orderidtype"> <xs:restriction base="xs:string"> <xs:pattern value="[0-9]{6}"/> </xs:restriction> </xs:simpleType> <xs:complexType name="shiptotype"> <xs:sequence> <xs:element name="name" type="stringtype"/> <xs:element name="address" type="stringtype"/> <xs:element name="city" type="stringtype"/> <xs:element name="country" type="stringtype"/> </xs:sequence> </xs:complexType> <xs:complexType name="itemtype"> <xs:sequence> <xs:element name="title" type="stringtype"/> <xs:element name="note" type="stringtype" minOccurs="0"/> <xs:element name="quantity" type="inttype"/> <xs:element name="price" type="dectype"/> </xs:sequence> </xs:complexType> <xs:complexType name="shipordertype"> <xs:sequence> <xs:element name="orderperson" type="stringtype"/> <xs:element name="shipto" type="shiptotype"/> <xs:element name="item" maxOccurs="unbounded" type="itemtype"/> </xs:sequence> <xs:attribute name="orderid" type="orderidtype" use="required"/> </xs:complexType> <xs:element name="shiporder" type="shipordertype"/> </xs:schema> The xsd and xml file are in the same directory.

  • F# Static Member Type Constraints

    - by Stephen Swensen
    I'm trying to define a function, factorize, which uses structural type constraints (requires static members Zero, One, +, and /) similar to Seq.sum so that it can be used with int, long, bigint, etc. I can't seem to get the syntax right, and can't find a lot of resources on the subject. This is what I have, please help. let inline factorize (n:^NUM) = ^NUM : (static member get_Zero: unit->(^NUM)) ^NUM : (static member get_One: unit->(^NUM)) let rec factorize (n:^NUM) (j:^NUM) (flist: ^NUM list) = if n = ^NUM.One then flist elif n % j = ^NUM.Zero then factorize (n/j) (^NUM.One + ^NUM.One) (j::flist) else factorize n (j + ^NUM.One) (flist) factorize n (^NUM.One + ^NUM.One) []

  • Example of testing a RPC call using GWT-TestCase with GAE

    - by Stephen Cagle
    How is that for a lot of acronyms! I am having trouble testing GWT's RPC mechanism using GWT's GWTTestCase. I created a class for testing using the junitCreator tool included with GWT. I am attempting to test using the built in Google App Engine using the created "hosted mode" testing profile created by junitCreator. When I run the test, I keep getting errors saying things like Starting HTTP on port 0 HTTP listening on port 49569 The development shell servlet received a request for 'greet' in module 'com.google.gwt.sample.stockwatcher.StockWatcher.JUnit.gwt.xml' [WARN] Resource not found: greet; (could a file be missing from the public path or a <servlet> tag misconfigured in module com.google.gwt.sample.stockwatcher.StockWatcher.JUnit.gwt.xml ?) com.google.gwt.user.client.rpc.StatusCodeException: Cannot find resource 'greet' in the public path of module 'com.google.gwt.sample.stockwatcher.StockWatcher.JUnit' I hope that someone somewhere has successfully run junit test (using GWTTestCase or just plain TestCase) that will allow for the testing of gwt RPC. If this is the case, could you please mention the steps you took, or better yet, just post code that works. Thanks.

  • Python string formatting when string contains "%s" without escaping

    - by Stephen Gornick
    When formatting a string, my string may contain a modulo "%" that I do not wish to have converted. I can escape the string and change each "%" to "%%" as a workaround. e.g., 'Day old bread, 50%% sale %s' % 'today!' output: 'Day old bread, 50% sale today' But are there any alternatives to escaping? I was hoping that using a dict would make it so Python would ignore any non-keyword conversions. e.g., 'Day old bread, 50% sale %(when)s' % {'when': 'today'} but Python still sees the first modulo % and gives a: TypeError: not enough arguments for format string

  • Resizing screenshots/screen captures for inclusion in Beamer

    - by Stephen
    Sorry, this may or may not be a programming question directly, but I am trying to resize screenshots with Imagemagick and Gimp to include in a Beamer presentation, but it comes out even blurrier than the resizing done by LaTeX. For instance, in Beamer I might have a command to rescale the image \includegraphics[width=.5\textwidth]{fig.png}. Using something like \begin{frame} \message{width = \the\textwidth} \message{height = \the\textheight} \end{frame} I have gotten the \textwidth and \textheight parameters in points (345.69548, 261.92444). So I have a script (in Python) that sends a system call to Imagemagick: 'convert %s -resize %.6f@ resized_%s' % (f,a,f) where a is calculated as \textwidth*\textheight*0.5**2. When I then go back into my Beamer presentation and include the resized figure, \includegraphics{resized_fig.png}, the size looks approximately correct but it's super-blurry. I also tried resizing in Gimp (using the GUI) but no luck either... help? Thanks...

  • What is so bad about using SQL INNER JOIN

    - by Stephen B. Burris Jr.
    Everytime a database diagram gets looked out, one area people are critical of is inner joins. They look at them hard and has questions to see if an inner join really needs to be there. Simple Library Example: A many-to-many relationship is normally defined in SQL with three tables: Book, Category, BookCategory. In this situation, Category is a table that contains two columns: ID, CategoryName. In this situation, I have gotten questions about the Category table, is it need? Can it be used as a lookup table, and in the BookCategory table store the CategoryName instead of the CategoryID to stop from having to do an additional INNER JOIN. (For this question, we are going to ignore the changing, deleting of any CategoryNames) The question is, what is so bad about inner joins? At what point is doing them a negative thing (general guidelines like # of transactions, # of records, # of joins in a statement, etc)?

  • Grails / GORM, read-only cache and transient fields

    - by Stephen Swensen
    Suppose I have the following Domain object mapping to a legacy table, utilizing read-only second-level cache, and having a transient field: class DomainObject { static def transients = ['userId'] Long id Long userId static mapping = { cache usage: 'read-only' table 'SOME_TABLE' } } I have a problem, references to DomainObject instances seem to be shared due to the caching, and thus transient fields are writing over each other. For example, def r1 = DomainObject.get(1) r1.userId = 22 def r2 = DomainObject.get(1) r2.userId = 34 assert r1.userId == 34 That is, r1 and r2 are references to the same instance. This is undesirable, I would like to cache the table data without sharing references. Any ideas?
