Extending the code of Python - adding language features

由 一曲冷凌霜 提交于 2020-01-01 16:31:11
问题 I have been programming in python exclusively for 4 years and have never really looked under the hood at the C code in which python is written. I have recently been looking into a problem that would involve modifying python at that level. The code seems pretty consistent, and thus relatively easily understood. However, it's complex enough that it wasn't making sense to me just by studying it how it all worked together. Granted, I didn't spend a lot of time or effort on that, for want of a

core dump filename gets thread name instead of executable name with core_pattern %e.%p.core

由 拜拜、爱过 提交于 2020-01-01 09:45:22
问题 I recently started setting some thread names within my application by using pthread_setname_np(). After doing this, if a crash occurs within one of the named threads, the core dump filename is getting the thread name instead of executable name with core_pattern %e.%p.core According to the core man page, the %e flag in the core_pattern is supposed to get expanded to the executable name. It doesn't say anything about the thread name. I want the executable name and not the thread name, because I

Override core jQuery functions on Element level

由 天大地大妈咪最大 提交于 2020-01-01 08:33:34
问题 Is it possible to override core jQuery functions on Element level, so for an example, i want to override val() function only on one <select> element. if i do something like this var element = $('select'); var old_val = element.val; element.val = function () { console.log('The new val'); return old_val.apply(this, arguments); } element.val(19); it works as expected, but as soon as i address the same field with new jQuery instance var element = $('select'); element.val(19); it stops working

Best way to modify OpenCart without touching Core and VQMOD/OCMOD

由 我的未来我决定 提交于 2020-01-01 05:30:13
问题 Is there a better way then using VQMOD / OCMOD to change OpenCart's core files? Is there some "overrides" folder exists so that I can simply create any PHP file corresponding to the file structure and simply override a core file? (Like it is possible in PrestaShop and Magento ). VQMOD / OCMOD is highly inconvenient. Does someone use any hacks & tricks to achieve the result? I don't want to touch any core files to keep the system clean and manageable. Thanks a lot! 回答1: If you want to call

Access .NET Core Configuration Class From Another Assembly

由 烂漫一生 提交于 2019-12-31 02:25:28
问题 In The Olden Days In a web.config file, settings could be placed in an appSettings section like so: <appSettings> <add key="mysetting" value="123"/> </appSettings> Even though my web.config file was in my web project, any assemblies/libraries used in that project could access the settings using: ConfigurationManager.AppSettings["mysetting"] Today (and the problem) I am starting to use .NET core, and just like before, I have assemblies/libraries that are not web projects in of themselves and

RabbitMQ-Spring整合

目录 Spring-boot中通过注解封装RabbitMQ的使用。 Spring通过XML配置使用rabbitMQ。 通过前面的RabbitMQ的java应用，我们初步了解到MQ的使用。在实际中，我们基本上都不需要这么用，可以直接通过把rabbitMQ整合Spring中，spring帮我们封装了一些消息者、生产者的功能，我们可以直接使用。 Spring-boot中通过注解封装RabbitMQ的使用。 1.添加依赖pom.xml <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-amqp</artifactId> </dependency> 2.配置服务器、用户、密码application.properties spring.rabbitmq.host=127.0.0.1 spring.rabbitmq.port=5673 spring.rabbitmq.username=root spring.rabbitmq.password=root spring.rabbitmq.publisher-confirms=true spring.rabbitmq.publisher-returns=true 3.通过注解定义队列、交换器等。 package mytest

Why below s3 and s5 String objects are differ, When s5 try to created in String pool it checks content s3 already have same content so s5 refers s3 object in string pool. But my assumption is wrong, then any one correct me. String s1="Buggy"; String s2="Bread"; String s3="BuggyBread"; String s4 = "Buggy"+"Bread"; String s5 = s1 + s2 System.out.println(s3==s4); // True System.out
