Continua CI Version 1.5 has been released (build 1.5.0.268); smaller, faster, loads of new features; Spring4D XE7 builds automated

Posted by jpluimers on 2014/09/10

I’m really happy that Continua CI Version 1.5 got released a few hours ago as per the Continua 1.5 released announcement.

It means that my Build Automation Session during the Dutch Delphi 2014 conference tomorrow can range from:

  • build using MSbuild from the command-line
  • build batch files
  • build using a custom front-end
  • build using Continuous Integration front-end

The session will explain lots of details about what various Delphi versions do, how to cope with dependencies, etc.

In the mean time, the preliminary Spring4D work on build automation is visible to guest users. Those include building for Delphi XE7 for the Win32, Win64 and OSX32 targets (in Debug and Release mode).

There is a huge list of Version 1.5 History @ Continua CI changes, which is partially quoted below.

For me these are the most important:

  • in-place upgrade without having to do any changes on my part
  • truckload of new features (including Delphi XE7, NuGet and Fake F# support)
  • smaller
  • faster

(as a side note: also FinalBuilder 7 was recently updated to support Delphi XE7)

In general, I like Continua CI a lot, most importantly because:

  • it is very stable
  • it has native support for a wide range of software development tools (including Delphi, Visual Studio and much more)
  • supports DVCS (like Git/Mercurial) just as you expect it to
  • if something breaks, you get a response and fix very very soon

You can download the new version through the Downloads @ Continua CI. These are the direct links:

For a breaking issue, there has been an important bug fix, so the new downloads are:

I created an RSS feed through Page2RSS to watch any new releases of Continua CI.

Parts of the changes in 1.5.0.268 1.5.0.278

The full list of changes are at Version 1.5 History @ Continua CI.

Be sure to also look at the official Continua 1.5 released announcement.

c# – What should I do when I am forced to write unreachable code? – Stack Overflow

Posted by jpluimers on 2014/09/09

Bosak posted an interesting piece of code on StackOverflow last year. His particular code was in C#, but it does not matter what kind of compiler you use:

Sometimes a compiler will complain about unreachable code, for instance when it thinks a function never returns a value.

But you know the program logic does.

Simple solution: When you have code that never should be reached: throw an appropriate exception.

public static int GetInt(int number)
{
    int[] ints = new int[]{ 3, 7, 9, int.MaxValue };
    foreach (int i in ints)
        if (number <= i)
            return i;

    return int.MaxValue; //this should be unreachable code since the last int is int.MaxValue and number <= int.MaxValue is allways true so the above code will allways return
}

The last return could be replaced like this, as proposed by Matt Houser: Read the rest of this entry »

Revisited from the .NET side: Why doesn’t WINWORD.EXE quit after Closing the document from Delphi? (via: Stack Overflow)

Posted by jpluimers on 2014/09/08

I long time ago, I asked about  [WayBack] Why doesn’t WINWORD.EXE quit after Closing the document from Delphi?.

It turns out that question is a lot harder in .NET than it is in Delphi. I already had a gut feeling of this when at clients I saw many more .NET applications leaking WINWORD.EXE stray processes than Delphi applications, even though both kinds were calling Quit on the Word application object.

Delphi has a deterministic way of coping with interfaces (hence you can do a One-liner RAII in Delphi, or make a memento): Interface references are released at the end of their scope.

.NET has non-deterministic finalization of the Common Language Runtime (CLR) and has Runtime Callable Wrappers (RCWs) around your COM references which are sometimes created “on the fly”.

The combination of non-deterministic finalization and RCWs can be very confusing, so lets start with the parts first. Read the rest of this entry »

When deadlocks become livelocks (via: Do deadlocks cause high CPU utilization? – Stack Overflow)

Posted by jpluimers on 2014/08/20

Depending on how you organize locks (for instance via waiting on semaphores or mutexes or spinlocks), deadlocks can become livelocks:

Inability to make forward progress because of conflicting spinlocks is usually referred to as ‘livelock’.

Thanks to Martin James for reminding me of that and Danny Thorpe for describing different ways of locking.

Be sure to read on deadlock prevention as well.

In the past, I used the XN Resource Editor, but it hasn’t been maintained for a while.

Which resource editor do you use?

Based on a few links I found, I will be trying these:

.NET/C#: Interesting DocX library to create OOXML documents for Word

Posted by jpluimers on 2014/07/10

In case I need to export DocX in .NET again: DocX – Home which is also at github.com/WordDocX/DocX

(I did it both with Word Automation and OOXML, they were a pain).
