从用户态的代码看fork();函数返回了两次,即在父子进程中各返回一次,父进程从系统调用中返回比较容易理解,子进程从系统调用中返回,那它在系统调用处理过程中的哪里开始执行的呢?这就涉及子进程的内核堆栈数据状态和task_struct中thread记录的sp和ip的一致性问题,这是在哪里设定的?copy_thread in copy_process struct...
we argue that fork was a clever hack for machines and programs of the 1970s that has long outlived its usefulness and is now a liability. We catalog the ways in which fork is a terrible abstraction for the modern programmer to use, describe how it compromises OS implementations, and propos...

To encrypt a database programmatically you can use the sqlite3_key function. The data provided in pKey is converted to an encryption key according to the same rules as PRAGMA key. int sqlite3_key(sqlite3 *db, const void *pKey, int nKey); PRAGMA key or sqlite3_key should be called ...
before fork collapse. This suggests that distinct actin pathways function in human cells during the replication stress and G2-phase DSB responses. During replication stress, PCNA-CB focus mobility was primarily confined and punctuated with bursts of diffusive or directed movement. Localized diffusive mo...
