C, which has very little of a runtime doesn't mask these at all and so "foists" the problems on the programmer. Managed languages tend to hide these to the benefit of the programmer, but which otherwise may have consequence in being able to write low level systems code.

This, but more words: Threads Cannot Be Implemented As a Library

Python exposes fork, heavily uses it (multiprocessing), also exposes threads, and can use threads behind your back, and also exposes libraries incompatible with fork (ctypes).

Python is an awful language for doing both of those things though. The runtime just wasn't designed with parallelism in mind.

CPython also has a Global Interpreter Lock (GIL) which prevents multiple threads from executing Python bytecode concurrently.

So unless the library is a thread library, it shouldn't ever call pthread_create(3) or clone(2) behind my back. Any API call that does need to prominently state in its documentation that, that's the behavior. Ideally is should also be obvious by the function name alone that it's likely to spawn a thread.

You just don't, do that.

Yes, on Unix/Linux.

On non-garbage platforms a library creating threads for its own internal use is a perfectly fine thing to do.

No. Some posts may come at an inopportune moment, so to give them the notability they deserve it's critical to have an online experience where posts can be relocated to the optimal context. This is a thus far unexplored community building mechanism which it has now become possible to implement thanks to the novel git rebase technology. For example:

code:

git checkout metoo # erroneously posted after "I think OP is wrong about everything"
git rebase imgay

Likewise, for optimal posting quality, it is necessary to be able to have a posting staging area with infinite stash depth, which has only now been enabled, also via the rich git feature set. Furthermore, if a discussion veers in an undesired direction, for example toward a conclusion that is not in line with current goals, you can easily conclude it in a posting timeline of your own using git clone technology, and refer to it when making passing remarks to your success in other contexts.

If you don't look so closely, you could do it with https://ikiwiki.info/. It's a blog/wiki engine that's backed by git. Comments posted on articles in the web UI get turned into commits, but you can pull/push content as git commits.

Jsor posted:

This is really just a newbie mistake and not a terrible horror, but it's such a basic memory bug it's kind of cute.

They're given this struct:
code:
typedef struct {
    int cap;
    TYPE *arr;
} DynArr;
Then they have to implement basic dynamic array/slice methods
code:
void _dynArrSetCapacity(DynArr *v, int newCap)
{
    assert(v != 0);
    assert(newCap > 0);
    DynArr *newV = realloc(v, newCap * sizeof(v));
    v = newV;
}
No, buddy, you're accidentally making an array of dynamic arrays and your pointer reassignment doesn't really do anything.

The instructor just made this same mistake on the answer sheet to the midterm. Which I think sends this from :shobon:

I was once wary of doing things like sizeof *v because I thought "what if v is null?" Then someone pointed out that sizeof is a compile-time thing and all was well.

I don't think it helps that people usually put the parentheses after sizeof like it's a function call. I'm not saying that's a bad idea, just that it added to my confusion.

When I still wrote C for work I'd see a lot of:

code:


SomeType *v ...
...
...sizeof(SomeType)

in some later code relating to v, and I would always suggest sizeof(*v), and get pushback for that exact reason.

I also always get a chuckle out of sizeof(char)

I think the latter is fine. It's just avoiding magic numbers.

Yeah, really don't get why people scoff at that. You, the compiler and I all know it's equal to 1. Sometimes I put sizeof(char) to show the units are "bytes" or for symmetry with other statements. It doesn't make my code any less correct or efficient. :shrug:

It's not a magic number, that is how sizeof is defined by the C spec. I'm not saying it is a horror to write it, just that I find it mildly amusing.

I think what he meant was using the literal 1 is a magic number in comparison to using sizeof(char) even if you know they are the same thing.

I worked on a Bukkit Plugin once and EVERY and i mean EVERY! line had casting so it went something like this

code:

Player player = (Player)world.getPlayer();
Storage storage = (Storage)player.getStorage();

Apparently he was new to java and learnt that things worked when cast so he just did it.
