APScheduler From the beginning to the end of reading the source code, I have spent , Here is another directory for reading , Even if it is truly complete ~
Advanced Python Scheduler(APScheduler) yes python The next super powerful timed task framework , The overall use is not difficult , It is worth learning and using
This article is my own study APScheduler In the process , I made a reading guide for all my notes , This includes instructions for use , Commonly used API Sort it out , And read the source code of all its core modules
A point that must be emphasized , All my source code parsing is based on APScheduler Of 3.6.3 edition
reminder : The title of this article can jump directly to specific articles ~
This article mainly translates official about APScheduler Introduction to entry level , What functions are provided , What requirements can be realized, etc
I also gave some examples that are more convenient to read , Easy and fast use of this library
This article mainly summarizes APScheduler Some key common functions provided by each module API
More complete API Arrangement , You can see Official documents
analysis APScheduler actuator executor Source code , Start with the simplest
analysis APScheduler Mission job Source code
Job The core part should be modified _modify() function , And the serialization and deserialization part of the code
It mainly introduces the base class BaseJobStore as well as 2 A more characteristic subclass MemoryJobStore as well as RedisJobStore
You can find JobStore The core is how to maintain a job.next_run_time An ordered list of standard sizes and how to save all tasks for easy retrieval ~
The basic class is introduced in detail BaseTrigger And execute once at a fixed time DateTrigger And running tasks at regular intervals IntervalTrigger, The overall code is not difficult ~
This article is mainly for CronTrigger Trigger paving , Sort out the implementation of all regular expression matching classes
In detail CronTrigger The implementation of the , Customized settings are made for each field of time , The idea of implementation is still worth understanding ~
Analysis of the OrTrigger and AndTrigger this 2 A composite trigger , Accidentally found some design problems bug, Finally, the following 2 A suggestion ：
OrTrigger Multiple... Are set at the same time in DateTrigger When !AndTrigger ! Of course, the above advice is based on 3.6.3 Version of , 4.0 Version bosses are developing , Look forward to their realization ideas
Base class for scheduling all modules BaseScheduler And one of its subclasses BlockingScheduler Source code analysis
It is the first series that I have finished , You can't praise me too much ~
