In particular, given the toplogy below: ```text A -- B -- C -- H master (hook declined) error: fail... (more) |

A: `git submodule foreach git pull` in parallel Git can't do this natively, but you can use git in combination with another command, such as GNU xargs First of all, fetching many repos in parallel is likely not worth it. Git fetch is likely to be limited by network speed or drive IO speed, not single core processing speed. Multiple instances of... (more) |

@alx My understanding is that the object at a memory address is whatever object was initially created there, regardless of whatever type a pointer to that address seems to be. For example, if you create an `int n`, it doesn't matter if you cast it like `float* a = (float*) &n`, the value pointed to b... (more) |

"if a union contains several structures that share a common initial sequence (see below), and if the union object currently contains one of these structures, it is permitted to inspect the common initial part of *any of them*" The way I read it, *any of them* is *any of the union members*, not *any s...

A: Storing more bytes than a union member has, but less than the union size, with memcpy(3) Reading from a union member who's size is larger than that of the last written member is explicitly allowed since C99, but the value of the extra bytes is unspecified. From the cppreference page on C unions: > If the size of the new type is larger than the size of the last-written type, the conten... (more) |
