(Standart C ++ derleyicisi, en uzun olası hata mesajı üretmesi kısa programı, yaz gcc, cl.exe, icc, veya clang).

Her girişin puanı, derleyicinin yaydığı en uzun hata mesajındaki karakter sayısıdır. Kaynak kodunuzda yer alan ve derleyici tarafından alıntılanan türler, tek bir karakter olarak sayılır.

Şablondaki bir şablonu her zaman uzun adlarla şablonda yeniden tanımlayabilirsiniz, ancak yaratıcı bir şey bekliyorum. Bunlardan bazılarını son kuralla önlemeye çalıştım, ama elbette kurallar daha iyi olabilir ve gelişmelerden memnun olacağım.

Etiketleri düzenledi. [Kolmogorov-karmaşıklığının] biraz gergin olduğunu itiraf ediyorum , ancak bu durumda ifade edici olduğunu düşünüyorum.

Şablon hata mesajlarını deşifre etmek eğlencelidir. Bunu düşün:

#include <vector>
#include <algorithm>
int main()
{
    int a;
    std::vector< std::vector <int> > v;
    std::vector< std::vector <int> >::const_iterator it = std::find( v.begin(), v.end(), a );
}

gcc -c error.cpp(4.6.3) ile derlemek, en uzun 330 karaktere sahip 15786 bayt çıktı üretecektir.

C ++ 'ın polimorfik özyinelemeyi destekleyip desteklemediğini görmek istediğimde bunu keşfettim (ve açıkça görebildiğiniz gibi bunu desteklemez). Haskell'de çok önemli bir polimorfik özyineleme örneği:

Prelude> let f :: (Show a) => a -> String; f x = show x ++ " " ++ f [x]
Prelude> f 0
"0 [0] [[0]] [[[0]]] [[[[0]]]] [[[[[0]]]]] [[[[[[0]]]]]] [[[[[[[0]]]]]]] [[[[[[[[0]] ...

İşte, işte bu başlatır gibi davranmaya Haskell gerektirir Show x, Show [x], Show [[x]], Show [[[x]]], sonsuza. Haskell , derleyici tarafından eklenen (Show x) =>işleve örtük bir parametreye dönüşerek bunu şöyle yapar f:

type Show a = a -> String

showList :: Show a -> [a] -> String
showList show []     = "[]"
showList show (x:xs) = '[' : show x ++ showItems xs where
    showItems []     = "]"
    showItems (x:xs) = ',' : show x ++ showItems xs

f :: Show a -> a -> String
f show x = show x ++ " " ++ f (showList show) [x]

C ++, tam anlamıyla şablon başlatma derinliği aşılıncaya kadar bu gibi örnekleri oluşturmaya çalışır.

— Joey

Polimorfik özyineleme ile neyi başarmaya çalıştığınızı açıklayabilir misiniz? Hem Haskell hem de C ++ 'da bir örnekte süreç sonsuz olduğundan, yalnızca fark, çalışma ya da derleme zamanında gerçekleşmesidir.

— sukhmel

@sukhmel Hayır, çünkü Haskell tembel olduğu için derlenecek ve koşacak (demo'd olarak)

— cat

@ catcat çalışmadığını ima etmedim, böyle bir çalışmanın asla durmayacağını ya da sürmeyeceğini belirttim. Althoug Joey'nin elde etmeye çalıştığı şeyin belirli bir şablonda durma şartı olması gerektiğini düşünüyorum, bu yüzden polimorfik özyinelemeyi denemenin arkasındaki fikrin ne olduğunu merak ediyordum.

Böyle bir model, ayrıca alırsınız: #define A(s) s##s##s##s #define B(s) A(s) #define C(s) B(B(B(s))) #define D(s) C(C(C(s))) D(foo). Bu bana çok daha az kodla ilgili bir hata mesajı veriyor ve Ackermann işlevini temelde uyguladığımız için herhangi bir boyuttaki deseni arttırmakla çok daha hızlı büyüyor .

VJo'ya benzer:
a.cpp:

int main() { return  
#include "a.cpp"  
#include "a.cpp"  
}

g ++ a.cpp

çok fazla çıktı üretir (öldürmeden önce en az 2 gigabayt)

Aşağıdaki kod bir kez karşılaştığım gerçek bir hatayı temel alır.

template <int i>
void bar();

template <int i>
void foo()
{
    bar<i>();
    char baz[i];
}

template <int i>
void bar()
{
    foo<i-1>();
}


int main(void)
{
    foo<2000>();

    return 0;
}

(gcc kullanarak)

Oldukça açık bir şablon özyinelemesi, ancak ftemplate-depth=100000bu çalışma için kullandığımdan beri bu bir hata üretmiyor. Hata mesajlarının asıl kaynağı -1'e düştüğünde char baz[i];hata üreten kaynaklardan gelir i.

Yaklaşık yarım saat sonra, 21.000 derleyici hatası , 300.000 satırlık hata mesajı ve derleyici tarafından kullanılan 280 megabayt RAM üzerinde oturuyorum . Ve durma belirtisi göstermiyor.

DÜZENLE:

Bir saat sonra, şimdi 36.000 derleyici hatası , 504.000 satırlık hata mesajı ve 480 megabayt RAM ... ve devam ediyor.

# 2 DÜZENLEME:

Yaklaşık yarım saat sonra:

ccplus1.exe has stopped working

Son istatistikler: 38.876 derleyici hatası , 544.624 satırlık hata mesajı, toplam 48.8 megabayt veri ve derleyici tarafından çökmeden önce kullanılan 518.9 megabayt RAM .

bu segfault için bir hata raporu gönderdin mi?

— tbodt

Mevcut LLVM versiyonumla (Apple LLVM versiyon 8.0.0 (clang-800.0.42.1)) artık segfault'u alamıyorum. Hala bir şey göndermem gerekip gerekmediğinden emin değilim - LLVM uzmanlarının eski bir böcekle ilgileneceklerinden şüpheleniyorum.

82 bytes: Bu, Joey Adams'ın yaklaşımına benzer şekilde çalışıyor , ancak hata mesajı -ftemplate-depth( std::set<T>aslında olduğu için std::set<T, std::less<T>, std::allocator<T>>) ile ilgili olarak üssel olarak büyüyecek .

Çünkü (x = -ftemplate-depth) >= 28, 1460 × 3 ^x -27 + 269x - 5381 bayt hata mesajı (gcc 7.2.0 tarafından derlenmiştir) olacaktır. Yani, varsayılan ayarlarda (x = 900), teorik olarak yaklaşık 4.9 × 10 ⁴¹⁹ bayt hata mesajı verir .

Açıklama olmadan returnhata mesajlarının sadece derlemenin sonunda üretileceğini unutmayın. (bu nedenle, varsayılan ayarlarda mesajları alamazsınız - ilk önce hafızanız tükenir.)

Uyarı: Bu programı derlemek çok fazla hafıza tüketecektir.

#include<set>
template<class T>T f(T a){return f(std::set<T>());}int main(){f(0);}
