, as requests. URL who will prepare it? It looks like the spider is preparing itself, so you can guess that the Scrapy architecture section (not including the spider) mainly does event scheduling, regardless of the URL's storage. Looks like the Gooseeker member center of the crawler Compass, for the target site to prepare a batch of URLs, placed in the compass ready to perform crawler operation. So, the next goal of this open source project is to put the URL management in a centralized disp

structure is broadly as followsScrapy mainly includes the following components: Engine (scrapy): Used to handle the entire system of data flow processing, triggering transactions (framework core) Scheduler (Scheduler): Used to accept requests sent by the engine, pressed into the queue, and returned when the engine was requested again. It can be imagined as a priority queue for a URL (crawling the URL of a Web page or a link), which determines what the next URL to crawl is, and remo

Turn: http://blog.csdn.net/kickxxx/article/details/7236040 Startup Mode MX51 supports four startup modes. These modes are determined by the solder joints on the IC Package (boot_mode 0/1). After reset, the two solder joints are sampled, then save their status to the SRC Boot Mode register (sbmr) Register. The solder joints correspond to logic 0. For logic 1, nvcc_per3 is recommended for Freescale. The four boot modes are internal, reserved, internal boot with fuses, and serial boot through USB/U
