• Queuing methods to be run on an object by different threads in Python

  - by Ben

  Let's say I have an object who's class definition looks like: class Command: foo = 5 def run(self, bar): time.sleep(1) self.foo = bar return self.foo If this class is instantiated once, but different threads are hitting its run method (via an HTTP request, handled separately) passing in different args, what is the best method to queue them? Can this be done in the class definition itself?

• Python dictionary to variable assignments based on key value to variable name

  - by Art

  Basically, I want to take a Dictionary like { "a":"bar", "b":"blah", "c":"abc", "d":"nada" } and use it to set variables (in an Object) which have the same name as a key in the dictionary. class Foo(Object) { self.a = "" self.b = "" self.c = "" } So in the the end self.a = "bar", self.b = "blah", etc... (and key "d" is ignored) Any ideas?

• Is it possible to bind arrays of literals in sqlite3-ruby?

  - by willb

  I'd like to execute the following sort of query through sqlite3-ruby: SELECT * FROM foo WHERE bar IN (:items) and bind :items to one or many literals. Is this possible? The obvious technique of passing the list of literals as an array as follows doesn't seem to work: db.execute("SELECT * FROM foo WHERE bar IN (:items)", :items=>[3,1]) (In the above example, only the first value in the array is bound to :items.)

• Using Constants in Perl

  - by David W.

  I am trying to define constants in Perl using the use Constant pragma: use Constant { FOO => "bar", BAR => "foo" }; I'm running into a bit of trouble, and hoping there's a standard way of handling it. First of all... I am defining a hook script for Subversion. To make things simple, I want to have a single file where the class (package) I'm using is in the same file as my actual script. Most of this package will have constants involved in it: print "This is my program"; package "MyClass"; use constant { FOO => "bar" }; sub new { yaddah, yaddah, yaddah. I would like my constant FOO to be accessible to my main program. I would like to do this without having to refer to it as MyClass::FOO. Normally, when the package is a separate file, I could do this in my main program: use MyClass qw(FOO); but, since my class and program are a single file, I can't do that. What would be the best way for my main program to be able to access my constants defined in my class? The second issue... I would like to use the constant values as hash keys: $myHash{FOO} = "bar"; The problem is that %myHash has the literal string FOO as the key and not the value of the constant. This causes problems when I do things like this: if (defined($myHash{FOO})) { print "Key " . FOO . " does exist!\n"; } I could force the context: if (defined("" . FOO . "")) { I could add parentheses: if (defined(FOO())) { Or, I could use a temporary variable: my $foo = FOO; if (defined($foo)) { None of these are really nice ways of handling this issue. So, what is the best way? Is there one way I'm missing? By the way, I don't want to use Readonly::Scalar because it is 1). slow, and 2). not part of the standard Perl package. I want to define my hook not to require additional Perl packages and to be as simple as possible to work.

• ByRef vs ByVal generates errors!?

  - by serhio

  ByRef vs ByVal generates errors!? I had a method that used an Object Function Foo(ByRef bar as CustomObject) as Boolean this method generated errors, because some strange .NET Runtime things changed the bar object, causing its Dispose()al. A lot of time spent to understand the thing(where the ... object is changed), until somebody replaced ByRef by ByVal and object wasn't change anymore when passing to this method... Somebody could explain this, what happens?

  Consider I have two arrays: $friends = Array('foo', 'bar', 'alpha'); $attendees = Array('foo', 'bar'); Now I need to populate a new array $nonattendees which contains only the elements which are in $friends array and not in $attendees array. i.e, $nonattendees array should be populated with 'alpha'. Is there any in built array operation available in PHP to achieve the above functionality or should I write my own for loops?

  It seems exceptionally heavy handed but going by the rule anything publicly available should be tested should auto-implemented properties be tested? Customer Class public class Customer { public string EmailAddr { get; set; } } Tested by [TestClass] public class CustomerTests : TestClassBase { [TestMethod] public void CanSetCustomerEmailAddress() { //Arrange Customer customer = new Customer(); //Act customer.EmailAddr = "[email protected]"; //Assert Assert.AreEqual("[email protected]", customer.EmailAddr); } }

• c++ object sizes

  Suppose I have: struct Foo: public Bar { .... } Foo introduces no new member varaibles. Foo only introduces a bunch of member functions & static functions. Does any part of the C++ standard now guarantee me that: sizeof(Foo) == sizeof(Bar) ? Thanks!
