Yes. Worse, though, is when I'm forced to write code that's not up to my quality standards, because the project manager doesn't want me to take the time to write it the right way. It makes me feel... well... dirty. :~
Marc Clifton wrote:

And how much time could be saved even before the release that you're skimping so that you can meet? Chances are pretty high in many cases that that code you rushed and did a bad job on will come back to haunt you sooner, not just later.
Marc Clifton wrote:

Refactoring happens in my code quite a bit - but it's less likely to happen in convoluted code that is hard to make sense of later when you come back to refactor. And the type of people who use "we can refactor later" as an excuse to write poor code are the ones who are the least likely to actually take the bother to refactor later.

Refactoring "should" occur when the design must change due to an analysis error or requirement change, not as an excuse to do crap work originally. And all of this is under the guise of "it's faster", which in my experience has never proven to be true, it's all bullshit. Anyway you don't need to believe me, see the web for Technical Debt[^]

Looking at bad code makes me cringe. When I look at something like a simple function that returns a string and the compiler warns about unreachable code detected and the code itself has multiple return points, I can't help but wonder, if simple code like this is so poorly implemented, warnings aren't fixed, and there's not comment to explain what the if statements and switch statements are even doing, what can I expect in complicated code?

There's NO excuse for not commenting your code. -- John Simmons / outlaw programmerThe similar circumstances that I see all too often is "we'll skip unit testing because of time pressure and catch all the errors in integration". Firstly the project will never catch up and second the integration will take longer without unit tests. I once did a phase review on a project where the manager had just decreed that no more unit testing or code reviews would happen in order to keep on schedule. My report stated that I considered that too risky. However, the project manager asked if it were certain that integration would take longer than scheduled and I had to say no, but it was high risk. He went ahead anyway. Guess what - integration took much, much longer than scheduled because of all the bugs they had to fix. :sigh: I didn't get much satisfaction from being proved right. I did the analysis and the extra time spent in integration was more than the time saved in unit testing and code reviews. So yes, code should be reviewed frequently even in the midst of the continuous fire drill. Bad code will bite you (or someone else) in the end. As for refactoring, my initial reaction was yes I do it all the time. But reading other replies I realised that I do it as part of the natural development process when writing the code in the first place or because I'm changing a piece of old code because it now needs to meet new requirements and it's architecture is no longer sufficient. I cannot think of any time when the code has been refactored just because it is messy.

I go through this everyday. The project I am working on was put together by a few developers that just had the attitude of get it working and worry about the rest later. The management throws around the word refactor for everything. They always say oh we will just refactor it later. Well the crap code piled up so high that it started causing hugh problems. They built it with out a solid design, commented nothing and they copied and pasted the same code in multiple classes all of the places, tons of hard coding and no oo design (they had no idea how to use inheritance or polymorphism). My initial roll on the team as the junior developer was to just help the senor guys out. Well 6 months later they fired both senor guys because everything they wrote started to break and I am stuck writing in this mess all day long. Its so bad I really don't like having my name associated with the mess. I go home sick to my stomach some days. Not to mention that sometimes I feel like I am not learning anything and I am starting to become a worse developer because of this mess. So after my rant I would say yes bad uncommented simple code leads to bad uncommented compiled code.
in my opinion you are actually learning a whole lot by being in this situation - you are learning about the importance of design and what it takes to make code maintainable, huge lessons for sure that will serve you well for many years to come - hang in there!

That's when it doesn't work. But its necessary as your in the eleventh hour and requirements are still coming in that break the design, yet there's no time to fix the design so in go the hacks. Then its a must to return and refactor, else the law of diminishing returns will bite later.

"we need to get something out, and we'll refactor it later".
This should make the alarm go off. I have over 10 years of experience in software development (most of them multi-million dollar projects) and there are 2 things that are always true: 1- If you are asked to "get something out", it is certainly how the whole project has been developped and managed. 2- Refactoring never happens, because companies don't see the point of redoing something that already works. From their standing point of vue, it is easy to understand, for they don't know the first thing on software development. Speaking of point number 2, the best approach to refactor the thing is to do it on a on-demand basis. Let me explain. If you are asked to work on code, it is probably to add new features or fix bugs. Take this occasion to refactor your "little piece". Like I said in point 2, refactoring code without improving what it is doing won't fly at management level. If possible, educate your co-workers, especially the junior ones. You know, Marc, the perfect world does not exist, nor do the perfect code. You are out there to make it better, though.

Right, because they'll quote a business need for it. For some reason developer productivity is never weighed in as a valid business need. If the design breaks from creeping requirements, and last minute hacks, it will eventually get out of hand, and turn into a mess of hacks and spaghetti. So maintenance is definately a business reason to refactor, but you can't always convince the powers that this is true.
This statement is false.

I agree - refactoring has become a bucket for all excuses. I believe it has its place but at a higher level than the method level. All code should be intended as production at all times. As needs change and grow then refactoring original design is warranted. Recognizing this allows us to not over-design for perceived future needs - especially when they always change and thus our design becomes wrong anyways. A systemic lack of comments and indicators like multiple return points (amongst many other subtleties) by a "senior" developer indicates a lack of personal drive to improve one's self (read a friggin' book!) - a lack of professionalism. These are the shots over the bow of not caring and likely bad, buggy code.
if(!connect()) return false; //continue with processing return true; That's a lot cleaner than bool ret = connect(); if(ret) { //continue with processing } return ret; And it saves a level of indenting. Maybe with 1280 x 1028 resolution this isn't such a big deal, but I still say there's nothing wrong with this style. Its just that, style.

Refactoring is about altering the structure of code/designs to accomodate new requirements (aka features, performance, etc.) It is not about making code "good." Code should always be good, if not fantastic. People who say that they will refactor their code later to make it "good" don't understand refactoring, nor the art and craft of programming.

Multiple return points when the logic is simple makes code more difficult to understand at a glance and to maintain. All too often I've added some functionality only to discover that there's a return statement I didn't notice earlier in the logic. This is not to say that I'm religious about it, I'm just conscious about the issue and make the decision based on code complexity. Here's the code that started this thread (obfuscated to protect the guilty):
public string Foo { get { switch (SomeType) { case TypeA: if (bar == null) { return null; } else { return bar.MyId.ToString(); } break; case TypeB: if (snafu == null) { return null; } else { return snafu.MyId.ToString(); } break; } return null; } set { q = value; } }There are so many things wrong with code, it's a perfect case study of bad programming. 1: the setter is setting something different than the getter. Since this is unusual practice, put a comment as to why 2: the getter is testing for null objects. Shouldn't this rather throw an exception if the object isn't initialized, but the object type is? 3: shouldn't there have been a flag raised when implementing that the object type is being decoupled from the object itself (see #6) 4: breaks never occur because of the returns 5: returns instead of a single return point 6: Since both types convert an ID to a string, why not create an abstract class or an interface so that container class maintains the interfaced instance and you can get the ID without the switch statement? 7: use to the ToString() method or have the object convert the ID itself to string, ie. GetIDAsString(), which is more flexible if later on, you want to do something different with the ID, like hash it, or whatever. So in these very few

Actually, I'll disagree. Ironically, you'll see exactly your example of "not cleaner" in my code.

IMO, refactoring has to happen. Even if you wrote code the right way to begin with, requirements change. When requirements change, your code architecture has to change to reflect that. Often times, that's where refactoring comes in for us.

Marc Clifton wrote:

We refactor when it's needed. I think the only exception is large refactors that would takes many, many months to complete. For example, after working in the same codebase for 2 years, we've recently started using test driven development. Much of our code up to this point wasn't designed with testing in mind, so if we really want to test a piece of code, it often has to be refactored. UI code is a big example here: I now see that most of the logic in our UI code simply cannot be tested because it's too intertwined with the UI code. So we've started to use the MVP pattern to seperate the logic and the UI code, thus allowing us to test the logic of the UI without getting entangled in UI code. But to take a timeout and refactor our hundreds of controls and forms to use the MVP pattern with unit testing would just be too huge a refactor. We simply don't have time to spend a couple months to do this. Instead, I'm migrating pieces at a time. Also, all new pieces use the MVP pattern with unit testing. So the code migrates over time. Besides the rare huge refactoring like that (maybe refactor isn't even the right word in that scenario), we do smaller refactors often, every day. Pulling interfaces out of classes, having consuming classes use interfaces (which can be mocked in unit testing) instead of concrete classes, renaming classes and namespaces to better reflect their usage (again, things evolve), making things simpler, the list goes on. In that sense, we refactor all the time. p.s.

That kind of refactoring, sure I'm fine with that. But the "I'll refactor the compiler warnings later" problem, hmmm. And I can understand refactoring architecture to add features, improve testing, etc. I don't agree with putting off even minimal thinking about architecture and "we'll refactor that later". Some things ought be done more or less right, with the knowledge available at the time, and not just "coded".

Refactoring "should" occur when the design must change due to an analysis error or requirement change, not as an excuse to do crap work originally. And all of this is under the guise of "it's faster", which in my experience has never proven to be true, it's all bullsh*t. Anyway you don't need to believe me, see the web for Technical Debt[^]
Oh I believe you. And thank you for the link. It's great writeup. Short and to the point. Marc

The similar circumstances that I see all too often is "we'll skip unit testing because of time pressure and catch all the errors in integration". Firstly the project will never catch up and second the integration will take longer without unit tests. I once did a phase review on a project where the manager had just decreed that no more unit testing or code reviews would happen in order to keep on schedule. My report stated that I considered that too risky. However, the project manager asked if it were certain that integration would take longer than scheduled and I had to say no, but it was high risk. He went ahead anyway. Guess what - integration took much, much longer than scheduled because of all the bugs they had to fix. :sigh: I didn't get much satisfaction from being proved right. I did the analysis and the extra time spent in integration was more than the time saved in unit testing and code reviews. So yes, code should be reviewed frequently even in the midst of the continuous fire drill. Bad code will bite you (or someone else) in the end. As for refactoring, my initial reaction was yes I do it all the time. But reading other replies I realised that I do it as part of the natural development process when writing the code in the first place or because I'm changing a piece of old code because it now needs to meet new requirements and it's architecture is no longer sufficient. I cannot think of any time when the code has been refactored just because it is messy.

Yup. I've got a situation where the following has been said: "we'll refactor in the unit tests when we've shipped the first version of the product." :laugh: :(( :laugh: :(( Marc

I call it code slamming - generally. Then there is the code clearly written by someone who has no passion for the quality of their product.
