General introduction to Gitlab CI
At fleetster, we built our own Gitlab instance, and we used Gitlab CI in large quantities. Our designers and testers are also using it, and they also like it. Its advanced features are amazing.
Gitlab CI is a very powerful continuous integration system with many different features, and new features will be added each time it is

On the Internet to read some of the PHP to JavaScript to pass the parameters of the problem, the use of Ajax technology, in the PHP side is basically the echo json_encoded method, and requires PHP files to clean, I want to develop in the CI framework, Allow controllers to pass some multidimensional arrays to the views, but a pass-through parameter will be displayed on the Web page using the Echo method. How can the data be transmi

Q: How do I trigger a workflow?
A:jenkins pipeline is available in three ways (if the plug-in that has SCM installed may have other ways to trigger), go to the Pipeline Settings page respectively. Wbhook (triggers a remote build (for example, using a script), timed trigger (build periodically), Code UPDATE trigger (Poll SCM)
Q:jenkins compiler environment is how to deal with, the actual user's
Docker4dotnet #5 Use VSTS/TFS to build a container-based continuous delivery pipeline,
In the past several d4d series, I have introduced how to use docker to support application development and packaging of asp.net core. The cross-platform development capability of Asp.net core is. net developers provide the ability to use containers for application development, this article describes how to use Microsoft's full lifecycle management platform VSTS/TFS
basic concepts of pipeline:
Source code: Integrated Gitlab Repository.
Stage: A pipeline can be divided into stages, each stage representing a set of actions. Note that stage is the concept of a logical grouping.
Step: Steps is the most basic operating unit, small to create a directory, large to build a docker image.

As the name implies, loaders are loaded elements, when using CI, often loaded with:
$this->load->library ()$this->load->view ()$this->load->model ()$this->load->database ()$this->load->helper ()$this->load->config ()$this->load->add_package_path ()
Copy Code code as follows:
/**
* Loader Class
*
* Users load views and files, common functions have model (), view (), library (), helper ()
*
* Controller's good assistant, $this-gt;load
Computer Composition 7 Pipeline Processor 7.2 Pipeline optimizationCompared to a single-cycle processor, pipelining can improve the performance of the processor, but it is not possible to take full advantage of the pipelining technology if only the steps that follow the instructions are used to slice the pipeline. So how can you tap into the more potential of
Introduction: Pipelines are the oldest IPC method on Unix systems, and pipelines provide an elegant solution: given the two processes that run different programs, how can the output of one process in the shell be used as input to another process? Pipelines can be used to 相关(一个共同的祖先进程创建管道) pass data between processes. FIFO is a variant of the pipeline concept, and one important difference between them is the communication that FIFO can use 任意进程间 .

Problem description
Jenkins2.0 Pipeline Frame IPipeline (that is, PLLL Library) set the trigger conditions for Mergeci to change merged mode and fixed, that is, the code to go after +2 points, Then the core member clicks the submit button to push the code into the library before triggering the MERGECI process, the VERIFYCI and mergec
PipedOutputStream and PipedInputStream
In Java, PipedOutputStream and pipedinputstream are pipe output streams and pipe input streams respectively.Their role is to allow multithreading to communicate between threads through the pipeline. PipedOutputStream and PipedInputStream must be used to support the use of piping communications.When using duct communication, the approximate process is that we write the data to the PipedOutputStream in thread A, w
1. Realization MethodAutomatic migration of data through an application requires that the source and target databases being manipulated exist, and that data migration policies (data pipelines) should also be established. Based on this, the data pipeline is used by the application to realize the automatic migration of data.2 . 1 Implementation StepsIn general, there are five basic steps to using a data pipeline
Data Pipeline provides a method for transferring data and/or table structures between different databases.
Data Pipeline objectTo complete the data pipeline function, you must provide the following content:The data source and target database are required and can be normally connected to the two databases.Tables in the source database;Where to copy the data to the
each process has a different user address space, the global variables of any one process can not be seen in another process, so the process to exchange data between the kernel, the kernel to open a buffer, process 1 data from the user space to the kernel buffer, process 2 and then read the data from the kernel buffer, This mechanism provided by the kernel is called interprocess communication (ipc,interprocess communication). As shown in. The current process communication methods are:
ci-Continuous Integration (1)-Software industry "pipelining" Overview 1 overviewContinuous integration (continuous integration) is a software development practice in which team development members often integrate their work, with each member being integrated at least once a day, which means that multiple integrations may occur on a daily basis. [1] Each integration is validated with automated builds (including compilation, release, automated testing)

A journey through the CPU pipeline Compilation: @ deuso_ict
AsProgramPersonnel, CPU plays a core role in our work, so it is not helpful for programmers to understand how the processor works.
How does the CPU work? How long does it take to execute a command? What does this mean when we discuss whether a new processor has 12 or 18 or even 31 pipelines?
Applications generally regard the CPU as a black box. The commands in the program enter the CPU
Unix IPC: Pipelines, Named Pipes (FIFO) Piping 1. ConceptA pipeline is a one-way (half-duplex), first-out, non-structured byte stream that connects the output of one process with the input of another. The write process writes data at the end of the pipeline, and the read process reads the data at the first end of the pipeline. When the data is read out, it is r
