SYN: Ultra-Scale Software Evolution Comprehension [ICPC 2023]

•

0 recomendaciones•15 vistas

The comprehension of very large-scale software system evolution remains a challenging problem due to the sheer amount of time-based (i.e., a sequence of changes) data and its intrinsically complex nature (i.e., heterogeneous changes across the entire system source code). It is a necessary step for program comprehension, as systems are not simply created out of thin air in a bang, but are the sum of many changes over long periods of time, by various actors and due to various circumstances. We present SYN, a web-based tool that uses versatile visualization and data processing techniques to create scalable depictions of ultra-scale software system evolution. SYN has been successfully applied on several systems versioned on GitHub, including the nearly 20-year history of the Linux operating system, which totals more than one million commits on more than 100k evolving files.

By Robert Fach, TechniSat Digital GmbH Attendees will learn about a system which solves a code reproducibility problem in the automotive systems area. The code reproducibility problem is defined as being able to rebuild a binary identical software release for a specific amount of time (up to 15-20 years after initial release) and to rebuild a software application with only small changes, keeping the unchanged parts binary identical with the related release. The problem complexity grows due to: external dependencies in a changing environment, a requirement to perform cross-platform builds, scaling issues (hundreds of gigabytes of source code) and more. The Technisat Dresden team achieved their goals by combining several tools in the right way: Jenkins + custom Jenkins plugin, SaltStack, KVM and SVN/Git.

Behind the growing interest in Generate AI and LLM-based enterprise applications lies an expanded set of requirements for data integrations and ML orchestration. Enterprises want to use proprietary data to power LLM-based applications that create new business value, but they face challenges in moving beyond experimentation. The pipelines that power these models need to run reliably at scale, bringing together data from many sources and reacting continuously to changing conditions. This talk focuses on the design patterns for using Apache Airflow to support LLM applications created using private enterprise data. We’ll go through a real-world example of what this looks like, as well as a proposal to improve Airflow and to add additional Airflow Providers to make it easier to interact with LLMs such as the ones from OpenAI (such as GPT4) and the ones on HuggingFace, while working with both structured and unstructured data. In short, this shows how these Airflow patterns enable reliable, traceable, and scalable LLM applications within the enterprise. https://airflowsummit.org/sessions/2023/keynote-llm/

Kubernetes is a fast growing open-source platform which provides container-centric infrastructure. Conceived by Google in 2014, and leveraging over a decade of experience running containers at scale internally, it is one of the fastest moving projects on GitHub with 1000+ contributors and 40,000+ commits. Kubernetes has first class support on Google Cloud Platform, Amazon Web Services, and Microsoft Azure. Unlike YARN, Kubernetes started as a general purpose orchestration framework with a focus on serving jobs. Support for long-running, data intensive batch workloads required some careful design decisions. Engineers across several organizations have been working on Kubernetes support as a cluster scheduler backend within Spark. During this process, we encountered several challenges in translating Spark considerations into idiomatic Kubernetes constructs. In this talk, we describe the challenges and the ways in which we solved them. This talk will be technical and is aimed at people who are looking to run Spark effectively on their clusters. The talk assumes basic familiarity with cluster orchestration and containers.

Short version: In this talk, I'll show how I migrated the backend for the NLJUG conference app (used for J-Fall, J-Spring and more events) from Spring running on Linux virtual machines to Quarkus running as GraalVM native image on AWS lambda. Long(er) version: A conference app backend makes the ideal candidate for a serverless architecture: almost no traffic during the year, and peak traffic during conference days. In this talk, I'll show how I migrated the backend for the NLJUG conference app (used to rate talks for conferences with 1500+ attendees) from a traditional approach with Java and Spring running on Linux VM's to a fully serverless architecture with Quarkus, GraalVM native images, AWS lambda, API gateway and DynamoDB. I'll talk about (and demo) the Quarkus development experience, migrating code to Quarkus, creating native images and the caveats involved, testing, deploying to AWS with the SAM CLI, monitoring, costs and more. After this talk, you'll know enough to get started with building and deploying Quarkus native images on AWS Lambda yourself!

Software development is carried out using Integrated Development Environments (IDEs). An IDE is a collection of tools and facilities to support the most diverse software engineering activities such as writing code, debugging, and program comprehension. Each activity is composed of many basic events, such as clicking on a menu item, opening a new tab to browse the source code of a method, or adding a new statement in the body of a method. These events are generally known as interaction data. In my Ph.D. dissertation, we proposed the concept of "Interaction-Aware Development Environments": IDEs that collect, mine, and leverage the interactions of developers to support and simplify the workflow of developers. To support this vision, we developed DFlow: a plugin for the Pharo IDE to model, record, and interpret interaction data. Pharo is a pure object-oriented programming language and environment that is very suitable for research. Besides I do not regret doing research inside a niche development environment, after my doctoral studies I felt the desire to transfer my knowledge to a more popular IDE. In this talk, I will describe my journey alongside CodeLounge that led from DFlow to Tako, an extension for Visual Studio Code that collects, aggregates, and visualizes interaction data.

Slides used for my PhD dissertation defense (13 November 2017). Thesis: “Interaction-Aware Development Environments enable novel and in-depth analyses of the behavior of software developers and set the ground to provide developers with effective and actionable support for their activities inside the IDE.” — Roberto Minelli, 2017 Abstract: Nowadays, software development is largely carried out using Integrated Development Environments, or IDEs. An IDE is a collection of tools and facilities to support the most diverse software engineering activities, such as writing code, debugging, and program comprehension. The fact that they are integrated enables developers to find all the tools needed for the development in the same place. Each activity is composed of many basic events, such as clicking on a menu item in the IDE, opening a new user interface to browse the source code of a method, or adding a new statement in the body of a method. While working, developers generate thousands of these interactions, that we call fine-grained IDE interaction data. In essence, this data captures the behavior of developers inside the IDE, but it is largely neglected by modern development environments. We believe that this data is a valuable source of information that can be leveraged to enable retrospective analyses and to offer novel support to developers. In this dissertation we propose the concept of "Interaction-Aware Development Environments": IDEs that collect, mine, and leverage the interactions of developers to support and simplify their workflow. We formulate our thesis as follows: Interaction-Aware Development Environments enable novel and in-depth analyses of the behavior of software developers and set the ground to provide developers with effective and actionable support for their activities inside the IDE. For example, by monitoring how developers navigate source code, the IDE could suggest the program entities that are potentially relevant for a particular task. Our research focuses on three main directions: 1. Modeling and Persisting Interaction Data. 2. Interpreting Interaction Data. 3. Supporting Developers with Interaction Data.

Interaction-Aware Development Environments

Roberto Minelli

As part of their daily work, developers interact with Integrated Development Environments (IDE), generating thousands of events. Together with other aspects of development, this data also captures the modus operandi of the developer, including all the program entities she interacted with during a development session. This "working set" (or context) is leveraged by developers to create and maintain their mental model of the software system at hand. Understanding how developers navigate and interact with source code during a development session is an open question. We present a novel visual approach to understand how working sets evolve during a development session. The visualization incrementally depicts all the program entities involved in a development session, the intensity of the developer activity on them, and the navigation paths that occurred between them. We visualized about a thousand development sessions, and categorized them according to their visual properties.

Visualizing the Evolution of Working Sets

Roberto Minelli

Integrated Development Environments (IDEs) lack effective support to browse complex relationships between source code elements. As a result, developers are often forced to exploit multiple user interface components at the same time, bringing the IDE into a complex, "chaotic" state. Keeping track of these relationships demands increased source code navigation and cognitive load, leading to productivity deficits documented in observational studies. Beyond small-scale studies, the amount and nature of the chaos experienced by developers in the wild is unclear, and more importantly it is unclear how to tame it. Based on a dataset of fine-grained interaction data, we propose several metrics to characterize and quantify the ``level of chaos'' of an IDE. Our results suggest that developers spend, on average, more than 30\% of their time in a chaotic environment, and that this may affect their productivity. To support developers, we devise and evaluate simple strategies that automatically alter the UI of the IDE. We find that even simple strategies may considerably reduce the level of chaos both in terms of effective space occupancy and time spent in a chaotic environment.

My slides for the presentation of our ERA paper at ICPC 2015 (International Conference on Program Comprehension). Abstract–Modern Integrated Development Environments (IDEs) are often affected by the “window plague”, an overly crowded workspace with many open windows and tabs. The main cause is the lack of navigation support in IDEs, also due to the many—and not always obvious—complex relationships that exist between program entities. Researchers have shown that it is possible to mitigate the window plague by exploiting the data obtained by monitoring how developers interact with the user interface of the IDE. However, despite initial results the approach was never fully integrated in an IDE. In our previous work, we implemented DFlow, an automatic interaction profiler that monitors all the fine-grained interactions of the developer with the IDE. Here we present a first prototype of the Plague Doctor, a tool that seamlessly detects the windows that are less likely to be used in the future and automatically closes them. We discuss our long term vision on how to fully exploit the interaction data recorded by DFlow to provide a more effective cure for the window plague.

My slides for the presentation of our full technical paper at ICPC 2015 (International Conference on Program Comprehension). Abstract–Developing software is a complex mental activity, requiring extensive technical knowledge and abstraction capabilities. The tangible part of development is the use of tools to read, inspect, edit, and manipulate source code, usually through an IDE (integrated development environment). Common claims about software development include that program comprehension takes up half of the time of a developer, or that certain UI (user interface) paradigms of IDEs offer insufficient support to developers. Such claims are often based on anecdotal evidence, throwing up the question of whether they can be corroborated on more solid grounds. We present an in-depth analysis of how developers spend their time, based on a fine-grained IDE interaction dataset consisting of ca. 740 development sessions by 18 developers, amounting to 200 hours of development time and 5 million of IDE events. We propose an inference model of development activities to precisely measure the time spent in editing, navigating and searching for artifacts, interacting with the UI of the IDE, and performing corollary activities, such as inspection and debugging. We report several interesting findings which in part confirm and reinforce some common claims, but also disconfirm other beliefs about software development.

My slides for the presentation of our vision at ICSE 2015 (International Conference on Software Engineering). Abstract–Developing software is a complex, intrinsically intellectual, and therefore ephemeral activity, also due to the intangible nature of the end product, the source code. There is a thin red line between a productive development session, where a developer actually does something useful and productive, and a session where the developer essentially produces “fried air”, pieces of code whose quality and usefulness are doubtful at best. We believe that well-thought mechanisms of gamification built on fine-grained interaction information mined from the IDE can crystallize and reward good coding behavior. We present our preliminary experience with the design and implementation of a micro-gamification layer built into an object-oriented IDE, which at the end of each development session not only helps the developer to understand what he actually produced, but also praises him in case the development session was productive. Building on this, we envision an environment where the IDE reflects on the deeds of the developers and by providing a historical view also helps to track and reward long-term growth in terms of development skills, not dissimilar from the mechanics of role-playing games.

Roberto Minelli

It is common knowledge that program comprehension takes up a substantial part of software development. This “urban legend” is based on work that dates back decades, which throws up the question whether the advances in software development tools, techniques, and methodologies that have emerged since then may invalidate or confirm the claim. We present an empirical investigation which goal is to confirm or reject the claim, based on interaction data which captures the user interface activities of developers. We use interaction data to empirically quantify the distribution of different developer activities during software development: In particular, we focus on estimating the role of program comprehension. In addition, we investigate if and how different developers and session types influence the duration of such activities. We analyze interaction data from two different contexts: One comes from the ECLIPSE IDE on Java source code development, while the other comes from the PHARO IDE on Smalltalk source code development. We found evidence that code navigation and editing occupies only a small fraction of the time of developers, while the vast majority of the time is spent on reading & understanding source code. In essence, the importance of program comprehension was significantly underestimated by previous research.

Quantifying Program Comprehension with Interaction Data [QSIC2014]

Roberto Minelli

Integrated Development Environments (IDEs) have become the de facto standard vehicle to develop software systems. The user interface (UI) of an IDE offers a staggering amount of facilities to manipulate source code, such as inspectors, debuggers, recommenders, alternative viewers, etc. It is unclear how developers use the UI of an IDE and whether such UIs actually give appropriate support to the developers. We present a visual approach to understand and characterize development sessions from the UI perspective. The tool supporting our approach mines and processes the finest-grained UI-level events making up development sessions and presents them visually. We have collected, visualized, and analyzed hundreds of development sessions and report on our findings.

Visualizing Developer Interactions [VISSOFT2014]

Roberto Minelli

Most development activities, like program understanding, source code navigation and editing, are supported by Integrated Development Environments (IDEs). They provide different tools and user interfaces (UI) to interact with the source code, such as browsers, debuggers, and inspectors. It is uncertain how and when programmers use different UI elements of an IDE and to what extent they appropriately support development. Previously we developed DFLOW, a tool that seamlessly records and processes interaction data. Our long-term goal is to assess to what extent the UIs of IDEs support the workflow of developers and whether they can be improved. As a first step we present our approach to analyze development sessions in the form of visual storytelling. We illustrate our initial catalogue of visualizations through two development stories.

Visual Storytelling of Development Sessions [ICSME2014]

Roberto Minelli

Developers use Integrated Development Environments (IDEs) to maintain and evolve software systems. IDEs facilitate development activities such as navigating, reading, understanding, and writing source code. Development activities are composed of many basic events, such as browsing the source code of a method or editing the body of a method. We call these actions “interaction data”. We believe that collecting, processing, and exploiting these interactions at run-time can potentially augment the productivity of developers. Our goal is to create self-adaptive IDEs: IDEs that collect, mine, and leverage the interactions of developers to better support the developers’ workflow. We envision a development environment that automatically and seamlessly adapts itself to support developers while maintaining and evolving software systems. To reach our goal, we will develop means to reshape the user interface of the IDE, interaction-based recommenders, and integrate live and adaptive visualizations inside the IDE. As a first step towards our vision, we have developed DFlow, a tool that non-intrusively records all IDE interactions while a developer is programming. At the moment DFlow collects all the interactions between the developer and the IDE, and enables retrospective analysis by means of software visualizations.

SAMOA – A Visual Software Analytics Platform for Mobile Applications [ICSM2013]

Roberto Minelli

Mobile applications, known as apps, are software systems running on handheld devices, such as smartphones and tablet PCs. The market of apps has rapidly expanded in the past few years into a multi-billion dollar business. Being a new phenomenon, it is unclear whether approaches to maintain and comprehend traditional software systems can be ported to the context of apps. We present a novel approach to comprehend apps from a structural and historical perspective, leveraging three factors for the analysis: source code, usage of third-party APIs, and historical data. We implemented our approach in a web-based software analytics platform named SAMOA. We detail our approach and the supporting tool, and present a number of findings obtained while investigating a corpus of mobile applications. Our findings reveal that apps differ significantly from traditional software systems in a number of ways, which calls for the development of novel approaches to maintain and comprehend them.
