请问下面的这段程序，是不是分配的内存再也回不来了？
main()
{
float * p = new float[100];
exit(1);
delete [] p;
}
我原来认为这肯定是memory leak，但是用valgrind检查，说是“still reachable”。
我曾经试着分配过很大的内存作试验，完了用top看内存好象并没有少一大块。
如果没有最后那句delete [] p，valgrind就会说“definitely lost”。两种情况都没
有free内存，难道因为程序里有一句delete，编译器就会产生不同的code，然后系统可
以把内存再拿回来？

发帖数: 155 | 3 纯动态也可以改。JIT里面有一种技术叫 On-stack replacement (OSR),就是target 怎
么把在stack上面的method替换成新的，优化过的版本。并且很多research work 都可
以在GC的时候update class type，这样可以在heap reachability analysis把老class
的object替换掉。 反正总之，只要你愿意，没什么不能做的. |

C++11有所谓的minimal gc support, n2670, 所谓reachability based leak

"
Large applications often consist of many stateful processes which must be
started and stopped in a particular order. The component model makes those
relationships explicit and declarative, instead of implicit in imperative
code.
Components provide some basic guidance for structuring a Clojure application

发帖数: 7142 | 8 我以为，
这个就是 graph reachable 的问题。
你从程序 local 和 global 开始往下扫描。
扫到的 mark， 从 heap 过一遍就可以清除没有扫描的。
这个是我自己乱想的啊。
这个循环依赖的清除 C 编译器里面也有。大概就是类似
这样的算法。 |

TCP does.
If the peer process dies, a FIN is sent from server. If you
try to send again,
you receive a SIGPIPE.
If the host dies, timeout occurs, the socket's pending error
set to ETIMEOUT.
If the host is not reachable, timeout occurs, and error set
to EHOSTUNREACH.
I would select() with timeout on read socket. This add
another application
level control. But, it is not necessary. |

发帖数: 87 | 13 同学，你在我这留这么长的回复，却好像和我的贴没啥关系呀。我可以收过路费吗？
我之所以开一个自己的帖子就是不想谈太多auditing 的technicality和system 的东西
（说实话，那个帖子太多terms, 对我这个局外者来说专业性太强）。我只是就我个人
这些年接触的auditor和tax professionals 谈一些个人看法。 不知道为什么你会觉得
我在贬低auditing这个job.如果说贬低的话，我最多是对某些auditor很无语。我一贯
对auditing的观点是，yes, it's absolutely necessary to get an audit done; and
no, I won't rely too much on that "unqualified" audit opinion.
audit VS. tax 哪一个更好，永远不会有个universal answer。每个人的career goal
不一样。有人志向远大，想做CFO，auditing 当然比tax 的路更广一些；但是也有人目
标相对略低一点，能升到tax director 或者四... 阅读全帖 |

发帖数: 12 | 18 It was claimed that the juror (or the others?) was not delibrating in good
faith, and that a verdict might not be reachable. I think it is normal,
even if it leads to no verdict. But making a public gesture and inviting
media scrutiny? I think the juror might be out of line.
I heard on TV people would solicit jurors's opinions after trials, and
their words could be used to appeal. The lawyer's advice to jurors: shut
up. It seems jurors could get into trouble if they choose to be careless.

发帖数: 318 | 23 i think it could be both. it depends on how g(1/mu)-g(y) goes to zero when y->1/mu.
(just write dy/[1/mu-g(y)] = mu*dx, and formally integrate from y=0 to g^{-1}(1/mu) which is the only singularity)
consider the following two cases:
(1) g(y) = y and (2) g(y) = 1/mu - sqrt(1/mu^2 - y);
the first one is unreachable for finite x, the second one is reachable. |
