In today’s digital landscape, maintaining the integrity of source code is crucial for delivering reliable and trustworthy software solutions. However, the increasing prevalence of attacks targeting source code repositories and version control systems (VCSs) poses significant challenges to source code integrity. Unauthorized access to source code repositories can lead to various security risks, including the introduction of malicious code or unauthorized approvals for pull requests. Security measures implemented on the remote server hosting the repository are typically insufficient to detect these types of attacks, resulting in changes potentially remaining undetected and becoming part of the deployed artifact. To address those issues, this study proposes GitBark, a framework that employs cryptographic methods to verify the integrity of a source code repository. GitBark achieves this by enforcing rules and policies on the commits made to the repository. Specifically, the study demonstrates that by formulating rules that utilize digital signatures, GitBark can effectively identify unauthorized changes and approvals. Moreover, GitBark prioritizes maintaining the local repository in a consistent and trustworthy state, reducing reliance on the remote server. Even if changes violating established rules are introduced to the remote repository, GitBark prevents their integration into the local repository. Consequently, users of GitBark can have confidence that their local repository remains a consistent and trustworthy version of the source code, without needing to place full trust on a remote server. An evaluation of GitBark, along with the devised rules, demonstrates its effectiveness in mitigating the threats identified in this study. Additionally, in terms of performance, GitBark incurs a modest overhead, both in time and storage., I dagens digital värld, så är det viktigare än någonsin att källkodens integritet upprätthålls. Detta är kritiskt för att kunna leverera tillförlitlig och kvalitativ mjukvara. Den ständigt ökade förekomsten av attacker som riktar sig mot källkodsrepon och versionshanteringssystem gör dock upprätthållandet av källkodens integritet svårt. Obehörig åtkomst till källkodsrepo ger upphov till flera säkerhetsrisker såsom inkluderandet av skadlig kod eller obehöriga godkännanden av nya ändringar. De säkerhetsåtgärder som finns implementerade på värdserven där källkodsrepot lagras kan generellt sätt inte detektera dessa typer av attacker, vilket resulterar i att dessa typer av ändringar oftast förblir oupptäckta. För att adressera dessa problem, så presenterar denna studie GitBark, ett verktyg som utnyttjar kryptografiska medel för att verifiera integriteten av ett källkodsrepo. GitBark gör detta genom att kräva regler för commits som görs till källkodsrepot och validera att de upprätthålls. Mer specifikt, så visar att studien att genom att formulera regler som uttnyttjar digitala signaturer så kan GitBark effektivt identifiera oauktoriserade ändringar och godkännanden. Dessutom, prioriterar GitBark att alltid bibehålla det lokala källkodsrepot i ett konsekvent och trovärdigt tillstånd, för att minska beroendet på en remoteserver. Även ifall ändringar som inte uppfyller reglerna introduceras på remote-källkodsrepot så ser GitBark till att dessa ändringar aldrig integreras i det lokala repot. Följaktligen så kan användare av GitBark känna sig säkra i att det lokala källkodsrepot alltid förblir i ett konsekvent och trovärdigt tillstånd i relation till dem etablerade reglerna, utan att behöva förlita sig på en remoteserver. En evaluering av GitBark, tillsammans med de skapade reglerna påvisar dess effektivitet i att adressera de identifierade hoten i denna studie. Dessutom, vad gäller prestanda så har GitBark en liten påverkan både i tid och utrymme.

In the research of Mining Software Repositories, code repository is one of the core source since it contains the product of software development. Code repository stores the versions of files, and makes it possible to browse the histories of files, such as modification dates, authors, messages, etc. Although such rich information of file histories is easily available, extracting the histories of methods, which are elements of source code files, is not easy from general code repositories. To tackle this difficulty, we have developed Historage, a fine-grained version control system. Historage repository is a Git repository which is built upon original Git repository. Therefore, similar mining techniques for general Git repositories are applicable to Historage repositories. Kataribe is a hosting service of Historage repositories, which enables researchers and developers to browse method histories on the web and clone Historage repositories to local. The Kataribe project aims to maintain and expand the datasets and features., MSR 2014 : the 11th Working Conference on Mining Software Repositories, May 31-June 01, 2014, Hyderabad, India

The global engineering design house Syntronic has requested a further development of the open source Python framework PyVISA-sim to enable dynamic simulations of signals and measuring instruments which would streamline development of their internal radio equipment testing tool. This tool is used by a world leading telecommunications company when developing their next generation radio equipment. PyVISA-sim is used in lab environments to test applications without access to real connected instruments. The project detailed in this thesis strives to pinpoint Syntronic’s needs, develop the requested functionality within the framework and have the changes implemented as part of the official GitHub repository, thereby making them available for anyone wanting to utilize them. To achieve this agile software development methods are utilized combined with an open source mindset. The resulting additions to PyVISA-sim can reduce the workload for all users in need of a more complex simulation method.

Many large companies use various business intelligence solutions to filter, process, and visualize their software source code repository data. These tools focus on improving continuous integration and are used to get insights about people, products, and projects in the organization. However, research has shown that the quality of measurement programs in software engineering often is low since the science behind them is unexplored. In addition, code repositories contain a considerable amount of information about the developers, and several ethical and legal aspects need to be considered before using these tools, such as compliance with GDPR. This thesis aims to investigate how companies can use repository metrics and these business intelligence tools in a safe and valuable way. In order to answer the research questions, a case study was conducted in a Swedish company, and repository metrics from a real business intelligence tool were analyzed based on several questions. These questions were related to software measurement theory, ethical and legal aspects of software engineering and metrics, and institutionalized theory. The results show how these metrics could be of value to a company in different ways, for instance by visualization collaboration in a project or by differentiating between read and active repositories. These metrics could also be valuable by linking them to other data in the company such as bug reports and repository downloads. The findings show that the visualizations could potentially be perceived as a type of performance monitoring by developers, causing stress and unhealthy incitements in the organization. In addition, repository metrics are based on identifiable data from Git, which according to the GDPR is classified as personal data. Further, there is a risk that these tools are used simply because they are available, as a way to legitimize the company. In order to mitigate these risks, the thesis states that the metrics should be anonymized

Software being developed today can have years worth of history and hundreds if notthousands of files involved in a single project. When trying to determine what parts ofthe code need maintenance or updating it can be difficult to determine what will beproblematic in the future. Hours spent on code that will not cause problems in thefuture could be better used in other areas. Before changes are made to a codebase, themost error-prone parts of the code should be identified. In this thesis a method forcomparing what factors contribute to future bugs is developed, as well as testing severalfactors extracted from version control metadata using this method. In addition, avisualization was made using tree maps to show the most problematic files in a readablemanner, effectively using the produced data in an application to predict future bugs. Itwas determined that Age of newest change, Changes with age reducing importance andPrevious bugfixes with age reducing importance were all the most impactful factors forpredicting future bugs but that different repositories worked best with differentcombinations of the mentioned factors.

Command line and version control skills are vital to computer science students during their education and as they enter the software industry. These skills are commonly taught to undergraduate students via traditional lecturing methods and brief hands-on activities. Many students struggle with learning the Git version control system because they are not familiar with the command line, or they do not understand how Git works internally. Recent research highlights the effectiveness of using interactive visualizations to teach computer science concepts. Thus, we developed novel command line and Git exercises with interactive visualizations. These exercises integrate with learning management systems to automate grading. We tested the effectiveness of the exercises in a CS2 course at a large research institution by conducting pre-assessments before and post-assessments after the students completed the exercises. We found that students performed significantly better on both the command line and Git post-assessments than on the pre-assessments. Furthermore, we found that students with less experience with the command line and Git achieved a significantly greater improvement from the pre-assessments to the post-assessments. Additionally, we found that students with different levels of command line and Git experience did not perform differently on the exercises. Therefore, the exercises provide a novel tool for teaching command line and Git concepts to undergraduate computer science students with any level of command line and Git experience.

The number of people working together in repositories grows every day. With increasing activity and interaction in a repository the amount of work required to maintain high quality and productivity is a problem. Automating workflows is a solution many developers lean towards in order to handle the problem but the effects of workflow automation is not yet determined enough to say that it actually helps. Based on GitHub’s workflow automation tool, GitHub Actions, this study looks at the effects of workflow automation by analysing the amount and speed of work in repositories on GitHub. To further understand the effects this study looks at the impact of the number of people interacting with a repository on the speed in which developers work. This study performs a statistical analysis on the difference between repositories that use workflow automation and those that do not to further increase knowledge of developers so that they can make informed decisions. Analysis on the effects of workflow automation shows that repositories that use it have an increased amount of committed code, more pull requests, uses issues more, faster pull request closure, and faster issue closure rates. In general repositories using workflow automation have more stars and contributors than those without. Analysis of the impact of the number of contributors show that usage of workflow automation increases with contributors. The study concludes that further research is required to determine if workflow automation is the causing factor of this or the implementation of workflow automation is an effect of increased activity in repositories.
