海外TECH	DEV Community	Debugging Tutorial: Java Return Value, IntelliJ Jump to Line and more	https://dev.to/codenameone/debugging-tutorial-java-return-value-intellij-jump-to-line-and-more-30f4	Debugging Tutorial Java Return Value IntelliJ Jump to Line and moreI just published the rd episode of the Second Duckling tutorial series and I m getting into the rhythm of doing them I posted the nd episode last week and in this post I ll dig deeper into both I tackled a lot of basic stuff about debugging but I picked two big headliners that a surprising amount of developers aren t familiar with E g How many times did you step over a return statement and cursed The original object isn t saved anywhere and you do not know what the return statement actually returned Or worse what if you accidentally stepped over code Wait What happened Can we go back Jump to line is the exact tool that enables that At the time of this writing I can guarantee that less than thousand developers used this feature But before we proceed here are the videos the nd and rd Shai Almog debugagent Duckling the rd How do you see the value returned from the method you stepped out of Also watch expressions evaluate change state and object marking which is a pretty amazing little known feature CodeNewbie SecondDucklings PM Feb Java Return ValuePlacing the return value from the method we just stepped out of is remarkably easy Yet it s off by default We can enable the Show method return values settings option in IntelliJ and it just magically works This begs the question of why is this useful feature off by default It s something I didn t address in the video due to lack of time The reason is performance The more elements you inspect the slower the application will be This means the IDE will bind instrumentation to the return keyword the underlying bytecode and collect information every time it s hit If the application feels slow disable such instrumentations If possible invest in newer hardware Especially more RAM Also make sure we allocate enough of that RAM for the IDE IntelliJ Jump to LineSo how do I know less than thousand developers used this feature Easy It s not a part of the IDE It s a feature that requires a plugin to support it Looking at the number of installs this is a feature that could benefit from some community awareness Once installed you can literally drag the current execution location to a different location Notice the state of objects isn t changed so you might need to edit values to get everything working This is super useful if you want to re try something You step over a method observe a side effect Then you can drag execution back and do it over again with different properties This is immensely useful in narrowing down problems It s also useful for testing We can try a method with different values again and again then generate use cases for that We can understand code coverage semantics better without restarting the app Object MarkingAnother feature that s absolutely remarkable and I just don t see in the real world is marking Maybe it s because people just don t understand what it means Marking is effectively the declaration of a new reference to an object Like declaring a new global variable This is super valuable Developers often track issues where they literally write on a piece of paper the object ID or pointer value for an object they re looking at With object marking we can give an instance a specific global name We can then reference that instance out of any scope E g when you re debugging and want to make sure that the object you re looking at in a method is the one that will be sent to another method and not a cloned copy Just mark the object with a name Then in the other method compare the argument to the marked object You can use this in conditional breakpoints to stop at the right location It s an amazingly useful feature Return ImmediatelyOne of the common problems we see when we manipulate state during debugging is the side effects A method can trigger errors because of that and effectively pollute the entire chain of debugging It s a waste We can just force a return from a point before the errors occur and provide a custom own return value Thus we can skip a problematic block of code This is a pretty niche feature but when you need it it s cool Drop FrameThis is something I didn t have time for I plan to cover it in a future video It s essentially an undo of a step into operation The stack is just unwinded by it It doesn t restore the state though so it isn t an exact undo operation Eagle eyed readers will also notice a feature called Throw Exception which does exactly that Its useful for some edge cases as validating code robustness and failure behavior I ll try to address that too in the future Changing StateUnlike the other features here many developers change the state of properties during debugging It s something most developers know about but don t do enough We need to keep this in mind when debugging source code and try to use it more TL DRThere are so many features in control flow and debugging This article barely scratches the surface of what s available to us When debugging classes we need to be aware of all the tools at our disposal	2022-02-23 13:47:30
海外TECH	DEV Community	Why you should deploy your next serverless application with Chalice and CDK 🐍	https://dev.to/kumo/why-you-should-deploy-your-next-serverless-application-with-chalice-and-cdk-3gap	Why you should deploy your next serverless application with Chalice and CDK You usually develop serverless applications with the Serverless Framework using Node js and face the challenge to develop one using Python You ve come to the right place To easily configure and deploy standard serverless patterns you should switch to Chalice as an Infrastructure as Code serverless framework Chalice natively integrates with CDK to deploy non Lambda related resources In addition leverage MyPy to preserve type safety while using AWS SDK The tooling that comes with Python serverless ecosystem is at least as mature as Node js one with packages like PynamoDB or AWS Lambda powertools Switching from Typescript to Python in a Serverless Architecture a good idea Serverless infrastructure is increasingly used Using serverless you can easily build fast and scalable web applications without wasting time managing infrastructure At Kumo we are strongly convinced that serverless is about to revolutionize the web The results of the Datadog study The State of Serverless reinforce our opinion It shows that the use of this technology is growing At the beginning of Lambda functions have been invoked times more often than two years before Our favorite stack leverages Typescript and the Serverless Framework to ship applications on AWS The whole team has good knowledge about this stack and can efficiently develop new features using familiar services and code patterns The Serverless Framework is very convenient to deploy Lambda functions However the Serverless Framework is very Lambda centric Provisioning other managed services requires relying on vanilla Cloudformation degrading considerably the developer experience Bridging the Serverless Framework with CDK the state of the art provisioning engine comes at a cost Sebastien Billes in his article gives some keys to combine the two but he concedes that “it does come with quite a bit of overhead Frédéric Barthelet also explained recently how to link the two The entire team being full stack developers the convenience to use a single language across the whole stack influenced us in using Typescript Datadog s study reveals that a vast majority of Lambda users prefer Python almost of the AWS Lambda functions are developed with Python Python is also a very good alternative as a runtime It has similar cold start durations compared to Node js ones It could be particularly relevant to use Python to develop serverless web applications in which we have to manipulate large amounts of data Let s dive into the state of the art Python serverless ecosystem and find out how it compares to our classical Typescript one Defining criteria to evaluate serverless PythonThe criteria I used to evaluate the use of Python as a runtime are based on our daily development experience I want to build a DX as convenient as the one we currently have in typescript Type safety of AWS tooling At Kumo we use typescript instead of javascript because type safety is very important to us We develop great web applications for our clients and we want these applications to be as stable as possible Boto the AWS Software Development Kit for Python is not typed well enough by itself MyPy is a good typing solution for Python and it includes better typing for boto Ease of deployment I explained before that one of the reasons why we like the Serverless Framework is its convenience in deploying our application I would like my Python application to be deployed as easily regardless of the framework I choose to use The next section explains why the Python framework Chalice paired with CDK satisfies our requirements Community maturity on AWS services The tooling provided by the community to use DynamoDB is a way to measure it We widely use the AWS NoSQL database DynamoDB in our projects We combine it with the node package dynamodb toolbox which provides abstracted interfaces additional validation parsing and data transformation features PynamoDB from the Python ecosystem matches features from its Node js counterpart Chalice A Python decorator based serverless framework What does it look like Chalice is a framework for creating serverless web applications in Python It is fully written in Python and designed only for this language Chalice provides a nice API to easily deploy Lambda functions It is a decorator based API similar to that of Flask The decorator is used to indicate the trigger of the Lambda HTTP route WebSocket Pure Lambda functions lambdas for which no trigger is defined can also be created with this framework Pure lambdas are very convenient for example when you want to integrate such lambdas in a step function where no decorator is in place to define such trigger This decorator API results in a very compact code to define the lambdas on the Chalice code As an example here is the code for three different lambdas with different triggers Lambda triggered on HTTP request POST on route apple app route apple methods POST cors cors config def create apple http create apple Lambda triggered on websocket connection app on ws connect def connect event WebsocketEvent item PK Connection SK event connection id dynamodb table put item Item item Pure lambda function app lambda function name CreateApple def create apple step function event context create apple A serverless application is even more readable using Chalice compared to the Serverless Framework The configuration code and the source code are gathered in the same file We understand the cause the trigger and the effect the code of each lambda at a glance It is worth mentioning that with Chalice only one lambda is deployed for all declared HTTP routes As a consequence all the logs will be gathered in a unique log group in CloudWatch CDK integration with Chalice the missing part of the Serverless FrameworkLet s focus on one of the main reasons why I decided to test Chalice instead of using the Python version of the Serverless Framework Chalice can be integrated with CDK more easily than with the Serverless Framework CDK resources can be used in Chalice code with environment variables and lambdas defined on the Chalice side can be referred to on the CDK side When building an application with Chalice and CDK you need a repository infrastructure for the CDK application and a runtime repository for the Chalice part To deploy your full application you will need to run the cdk deploy command in your infrastructure repository Here is the architecture of a simple project ├ーinfrastructure│├ーapp py│├ーcdk json│├ーrequirements txt│└ーstacks├ーrequirements txt└ーruntime ├ーapp py └ーrequirements txtAll the code needed to define the lambdas is written on the Chalice side Other AWS resources are deployed by directly writing CDK Constructs which is very good at defining complex resources and infrastructure Here is an example of the way we can deploy a step function which refers to lambda function defined on the Chalice side The get function is used to refer to the lambda functioncreate apple tasks LambdaInvoke self CreateApple lambda function self chalice get function CreateApple step function definition choose wait time next wait x next create apple next success state machine sfn StateMachine self CreateAppleMachine definition step function definition As you can see I simply use the get function to refer to the pure lambda CreateApple defined in the previous section This way I create the create apple step that I can integrate into the pipeline of the step function definition ConclusionIf you need to switch to Python to develop your next serverless application do not worry Chalice is a mature serverless framework with a lot of advantages configuration with decorators native CDK integration for non Lambda resources The tooling surrounding the serverless Python ecosystem has a great maturity Walking the path from Typescript to Python will not be an easy task but the destination is worth it	2022-02-23 13:38:39
