The project I am currently working on started on 1/1/2008. At that point, Qt 4 was still commercial for commercial use. Since my company had purchased Qt 3, and Qt 3 covered the requirements of the project, it made sense not to spend another 3K$ for Qt 4. Some months later Qt 4 became open source, but then it was late.

The problem described above is unacceptable for professionally written code, no matter how old the version. Trolltech should have not released it, the code wasn't ready. I accept that old libraries may be missing functionality, but I do not accept such big problems. And this problem is huge, a big showstopper.

I know that professionally written code can be sh1tty, I just did not expect Trolltech's code to be that sh1tty. Trolltech is supposed to have the best C++ toolkit out there.

EDIT:

Fixing Trolltech's code has multiple consequences for many people. I put a mutex lock around certain non-thread safe functions, which made the application slower. The tester could not run the application in the test environment, that was a virtual machine, and now he is trying to persuade the system administrator that he needs another brand new PC for the test.

C++ has a reverse function. Not only does it work on strings but it works on any kind of array-like or list-like type!

But hes acting like its a surprise especially 10 year old code that still had to worry about performance issues from making a class like QString thread safe.

If he's modifying Qt anyhow, it'd probably be better to make it NOT use a static QRegex, than to wrap certain things in a mutex.

What does that tell you about the other toolkits?
