Preprocessor seams and assignment of responsibility

Preprocessor seams and assignment of responsibility 110

Posted by Brett Schuchert Thu, 22 Jul 2010 15:32:00 GMT

In my previous blog I mentioned adding a single method to the cslim library:

cslim/include/CSlim/SlimListSerializer.h:
void SlimList_Release(char *serializedResults);
cslim/src/CSlim/SlimListSerializer.c:
void SlimList_Release(char *serializedResults)
{
  if(serializedResults)
    free(serializedResults);
}

Now I’m going to explain how I came across this need, what it took to figure it out and then why I picked this solution.

Background

In FitNesse, Query Table Results are a list of list of list:

The outer-most list represents “rows”. It collects all objects found. It has zero or more entries.
The inner-most list represents a single field. It is a key value pair. It is a list of size 2. The first entry is the name of the field (column to FitNesse). The second field is the value. Both are strings.
The middle list represents a single object. It is a collection of fields. It has zero or more entires.

I understand the need for this representation and it takes a little bit to get it built correctly. So much so, I built a simple tool to do it in java.

C++ is no different. In fact, the authors of cslim though the same thing and they created a C Abstract Data Type to help out (and an add-on method to create the correct final form):

SlimList
SlimList_Serializer

They use C because it can be used by both C and C++. I’m using C++ and I wanted to make building query results even easier, so I built a QueryResultAccumulator. The most recent source is in the previous blog and I’ll be putting it on github after I’ve had some more time to work on it.

Here’s the progression to my QueryResultAccumulator class:

Wrote a Query-Table based fixture and followed the example provided with cslim (thank you for that!)
Moved the code from functions into methods on a class
Extracted a class, called SlimListWrapper, which made the fixture code easier to follow.
Went to get takeout and realized that I had named the class incorrectly and that it was really accumulating query results (thus the name). The SlimList was a mechanism, not an intent.
Refactored the class into QueryResultAccumulator (I left the original alone, created a new class, copied code from one to the other and changed it around a bit.

Now it might sound like I didn’t have any tests. In fact, I did. I had my original Acceptance Test in FitNesse. I kept running that, so in a sense I was practicing ATDD.

I was not happy with that, because I was not sure that I had properly handled memory allocation correctly. In fact, I had not. The final result is dynamically allocated and I was not releasing that. So I “fixed” it. (It needs to be released after the return from slim back to FitNesse, so the typical pattern is to lazily delete it, or release it in a “destroy” method called after the execution of a single table.)

I have a memory leak?!

I am simplifying this story a bit. So I’m skipping some intermediate results. Ultimately I wrote the following test to check that you could use a single query result accumulator for multiple results correctly:

TEST(QueryResultAccumulator, CanProduceFinalResultsMultipleTimes) {
    QueryResultAccumulator accumulator;
    accumulator.produceFinalResults();
    accumulator.produceFinalResults();
}

This caused a memory leak of 60 bytes. It was at this point I was up too late and banging my head against a wall. About 3 hours later I figured that out and went to bed. I fixed the problem and sent a patch to authors of cslim in maybe 45 minutes. So I should have gotten more sleep.

Where is that damn thing

In any case, I visually checked the code. I debugged it. I did everything I could initially think of, and I was convinced that my code was correct. (As we’ll see it both was and was not due to a preprocessor seam in cslim.) I got to the point where I even tried different versions of gcc. (I found a parsing error in g++ 4.5 when handling templates, so in desperation and late at night I wasted 5 minutes switching my compiler.) I had the following code in my class:

  if(result)
    free(result);

This was the correct thing, but it was in the wrong location. Again, this was related to a preprocessor seam in cslim.

Eureka!

I looked at the cslim code and confirmed it was doing basic C stuff, nothing surprising. It was at that point that I remembered something important:

cslim depends on CppUTest and uses a different malloc/free

Ah ha! That’s it. So I tired to recompile my C++ code to use the same thing. However, I was not able to do that. CppUTest’s memory tracking implementation does not work with many of the C++ standard classes like <string> and <vector>. So I could not compile my code using the same approach.

I’m glad this happened becuase it made me realize that it was the wrong place anyway. Here’s the logic:

CSlim has a preprocessor seam, comile with or without -Dfree=cpputest_free, -Dmalloc=cpputest_malloc
I’m using a class in cslim to do the allocation, where the policy of allocation is stored
I should not release the memory but instead allow the cslim library to release the memory becaue it has the allocation policy, and therefore the release policy.

About 2 minutes later, I had added a single function to the library:

cslim/include/CSlim/SlimListSerializer.h:
void SlimList_Release(char *serializedResults);
cslim/src/CSlim/SlimListSerializer.c:
void SlimList_Release(char *serializedResults)
{
  if(serializedResults)
    free(serializedResults);
}

I updated my QueryResultAccumulator to use SlimList_Release and my false positive disappeared.

It also turns out that this improved symmetry in the library. To allocate and release entries in an SlimList you use the following functions:

SlimList* SlimList_Create()
void SlimList_Destroy(SlimList*);

Now to serlalize a list and release the memory later you use:

SlimList_Serialize
SlimList_Release

As I write this, I think there’s a better name. I’ll let the authors give it a better name (like SlimList_Release_Serialization_Results). But in any case, if you use a function in the cslim library that allocates something, you use another method in the cslim library to release it.

Since the libray has a preprocessor seam, that symmetry removes a false-positive memory leak.

What took so long?

I had an interesting time with this. Originally I had not released that memory in the class but rather in the unit test. I was working too late and not thinking clearly. I realized that my class needed to manage that.

When I called free in the unit test, it was calling the correct version of free, cpputest_free, becasue it was a unit test using CppUTest. When I moved the code into the class, which has no knowledge of CppUTest (nor can it), the flow of the code was correct, but the compilation (preprocessor symbols) were different and it caused a false positive.

Since I changed the code, I assumed it was a problem with how I changed the code. To me more clear, I though it was a code-flow problem, not a preprocessor seam problem. So I spent a lot of time verifyig my code. Once I determined it was correct, I then moved into debugger mode.

It was not long after that when I finally figured out what was going on.

Conslusions

As with many things in life, this is intuitive once you understand it!-)

That cslim depends on CppUTest might be questionable. However, if I treat cslim as a (mostly) black box, and I don’t know its allocation policy, I should not assume a deallocation policy.

By putting the responsiblity in the correct library level, it fixed the problem and added symmetry to the overall solution.

I also really enjoyed this (after it was done). I’ve come across memory leaks using CppUTest in the past. Often they were my fault. Sometimes they were not. This was interesting because it both was and was not my fault. I originally had written the code incorrectly. When I put he correct steps in my code, I still had wrong code because I put the responsibility in the wrong place. It really was only correct after I moved the actual implementation into the library and then called it from my code that I had finally written it correctly.

Where You Can Buy Useful Golf Accessories about 1 year later:

There are many different golf accessories that can make the sport more enjoyable for you. These range from cases to protect your clubs, to small handheld score calculating computers. If you have a product in mind, you can probably find it at your local golf club store. However, sometime local golf stores won? have as big of an inventory as you would like to browse, or they simply Cheap Nike Gladiator Sandals carry the item at all. If this is the case, then you will have to look elsewhere for your desired golfing accessory. There are several things you can do to track down what you want.

First of all, you should monitor classified ads in as many resources as you can. The internet offers many different places for people to post their ads, on China wholesaler online store like CraigsList.com. Keep an eye out on these sites for anyone with the product that you want, so that you can immediately call them up and get the first dibs. Local newspapers are good as well, and also offer yard sale advertisements that might lead you to finding what you need. If you head to the right parts of town for yard sales, you will find quite a few people who are looking to unload their old golf equipment. As long as what you want isn? too modern, you might be able to find it.

You can also look on sites that are meant to sell the items online. EBay is the one that comes to mind first for most people, and this is a very good place to look. EBay is one of the biggest repositories of all things old and no longer widely available. However, there are also quite a few online golf accessory China wholesale Nike Gladiator Sandals that may offer what you need. The bigger stores are generally more reliable and more trustworthy than the average eBay seller, and they also sell new items. As long as you are sure that you are getting a quality item and not some cheap version that will break right away, these sites are very good to check out. Your favorite search engine will quickly lead you to an abundance of them.

Your fellow golfers are another great resource when it comes to getting useful golf accessories. Golfers tend to go through more accessories than players of any other sport, so you can usually count on some of your golfing buddies to have some old items that they wouldn? mind parting with. You can offer a percentage of the retail value, or you can simply ask for it for free. Usually golfers will understand the compulsion to accessorize, and will not mind hooking up someone who is an ally. Take advantage of this camaraderie if you can, and avoid making unnecessary trips to the golf store to buy overpriced accessories.

If you try all of these different resources China wholesaler online store , you are almost guaranteed to find what you need. Just remember to be thrifty when it comes to golf equipment. Even if you feel like you can afford it, you still don? want to get too free with your wallet and start tossing checks everywhere for all kinds of equipment. This is a good way to waste huge amounts of money without having much to show for it in the end except for a bunch of accessories that you might not use very much.
