ci pipeline

MongoDB: Gathering Pipeline, It appears in MongoDB2.2. A data aggregation framework based on data processing pipeline conceptual modeling. The document enters a multi-stage pipeline that can convert the document into clustering results. The clustering pipeline provides a substitute for the map-reduce method and is the

The use of Pipeline design patterns in Laravel-exploring the principle of Middleware implementation the so-called Pipeline design pattern is to transfer data to a task sequence, and the Pipeline plays the role of the Pipeline, the data is processed here and then transmitted to the next step.

1. Background Once I met this requirement: application a (which can be encoded and compiled by myself) calls a console application B (which cannot be modified by a third party ), console program B prints data on the standard output device (similar to the command line window). Application A needs to obtain and process the data. After this requirement is met, the following implementation methods are summarized: "Pipeline" and "redirection ". This sectio

Create a "mini-version" of the pipeline to simulate the real pipeline request processing processFrom the ASP. NET core Pipeline depth profile (1): Processing HTTP requests with pipelines we know that the ASP. NET core request processing pipeline consists of a server and a set of ordered middleware, so it is very simple

CI session is not the original session, is my previous cookie based session, in addition, CI can be configured according to the user choose whether the session into the database, I like this function, there is "flash data" function, The flash data is only available for the next server request and is then automatically cleared. Common use methods are: $this->session->set_userdata (' some_name ', ' some_valu

CI is not the session of the original session, it is all of my previous cookie based session, in addition, CI can be selected according to the user configuration will be stored in the database session, I like this function, there is "flash data" function, Both flash out the data only to the next server request can, and then will be automatically cleared. Common use methods are: $this->session->set_userdata

inter-process communicationeach process has a different amount of user address space, the global variables of any process can not be seen in another process, so the process to exchange data must pass through the kernel, in the kernel to open a buffer, process 1 data from the user space to the kernel buffer, Process 2 Then reads the data from the kernel buffer, a mechanism provided by the kernel called interprocess communication (ipc,interprocess communication). the way to implement interprocess

Here, finally into the core of the CI framework. Since it is a "boot" file, it is the user's request, parameters and so on to do the corresponding guidance, let the user request and data flow according to the correct line position. For example, the user's request URL: Http://you.host.com/usr/reg The boot file is actually handed to the Usrcontroller controller in application for the Reg method to be processed. What did codeigniter.php do in this

The reason that ASP. NET core is a Web development platform is that it has a highly extensible request processing pipeline that we can customize to meet the HTTP processing needs of various scenarios. Asp. NET core applications, such as routing, authentication, sessions, caching, and so on, also customize the message processing pipeline to achieve. We can even create our own web framework on the ASP. In fac

-------------------------------------------------------------------------------- Download all source programs in this section Overview Windows introduces multi-process and multi-thread mechanisms. At the same time, it also provides communication means between multiple processes, including clipboard, DDE, Ole, and pipelines. Compared with other communication means, pipelines have their own restrictions and characteristics, the MPs queue is actually a shared memory zone where the process places th

New appearing in the MongoDB2.2.Aggregation pipeline data aggregation framework based on conceptual modeling of data processing pipelines. The document enters a multi-stage pipeline that translates the document into aggregated results.The aggregation pipeline provides alternatives to the Map-reduce method and is the preferred solution in many aggregation tasks, b

Preface to the message processing pipeline for the Web APIMVC has a mechanism for request processing, and of course the Web API has its own set of message-processing pipelines, which are always done through Httpmessagehandler. We know that the request information exists in the Requestmessage, and the response information exists in Responsemessage, when the request information enters the pipeline, at this ti

nameless pipes (pipe)Pipelines can be used for communication between affinity processes, and well-known pipelines overcome the limitations of pipe without name, so that, in addition to having the functions of a pipeline, it allows communication between unrelated processes;define function: int pipe (int filedes[2])Filedes[0] is the read end in the pipeFILEDES[1] is the write end of the pipeline.Implementation mechanism:A
