Texto completoTo cope with the complexity of large object-oriented software systems, developers organize classes into subsystems using the concepts of module or package. Such modular structure helps software systems to evolve when facing new requirements.The organization of classes into packages and/or subsystems represents the software modularization. the software modularization usually follows interrelationships between classes. Ideally, packages should to be loosely coupled and cohesive to a certain extent. However, Studies show that as software evolves to meet requirements and environment changes, the software modularization gradually drifts and looses quality. As a consequence, the software modularization must be maintained. It is thus important to understand, to assess and to optimize the organization of packages and their relationships. Our claim is that the maintenance of large and complex software modularizations needs approaches that help in: (1) understanding package shapes and relationships; (2) assessing the quality of a modularization, as well as the quality of a single package within a given modularization; (3) optimizing the quality of an existing modularization. In this thesis, we concentrate on three research fields: software visualizations, metrics and algorithms. At first, we define two visualizations that help maintainers: (1) to understand packages structure, usage and relationships; (2) to spot patterns; and (3) to identify misplaced classes and structural anomalies. In addition to visualizations, we define a suite of metrics that help in assessing the package design quality (i.e., package cohesion and coupling). We also define metrics that assess the quality of a collection of inter-dependent packages from different view points, such as the degree of package coupling and cycles. Finally, we define a search-based algorithm that automatically reduces package coupling and cycles only by moving classes over existing packages. Our optimization approach takes explicitly into account the original class organization and package structure. It also allows maintainers to control the optimization process by specifying: (1) the maximal number of classes that may change their packages; (2) the classes that are candidate for moving and the classes that should not; (3) the packages that are candidate for restructuring and the packages that should not; and (4) the maximal number of classes that a given package can entail.The approaches presented in this thesis have been applied to real large object-oriented software systems. The results we obtained demonstrate the usefulness of our visualizations and metrics; and the effectiveness of our optimization algorithm
Le, Dilavrec Quentin. "Precise temporal analysis of source code histories at scale". Electronic Thesis or Diss., Université de Rennes (2023-....), 2024. http://www.theses.fr/2024URENS003.
Texto completoSoftware systems play a central role in contemporary societies, continuously expanding and adjusting to meet emerging requirements and practices. Over the years, through extensive development efforts and numerous code updates, those systems can accumulate millions of lines of code. Moreover, they exhibit complexity, configurability, and multi-language characteristics, relying on large and complex build pipelines to target multiple platforms and hardware. This requires extensive code analyzes to maintain code, monitor quality and catch bugs. Automated code analysis is a resource-intensive process primarily designed to examine a single specific software version. Presently, existing code analysis methods struggle to efficiently evaluate multiple software versions within a single analysis, taking up an impractical amount of time. This type of code analysis, which scrutinizes software code over several moments of its existence, is referred to as "temporal code analysis." Temporal code analyses open new opportunities for improving software quality and reliability. For example, such analyses would permit to fully study how code and their tests co-evolve in a code history. To overcome the different challenges that prevent such analyses to run at large scale, this thesis makes the following contributions. This thesis first demonstrates the feasibility of analyzing source code changes to identify causality relations between changes (ie. co-evolutions). The second contribution addresses the efficiency of computing fine-grained changes and their impacts from code histories. This required to revisit how source code histories are represented and processed, leveraging the structured nature of code and its stability through time. It led to an approach, called HyperAST, that incrementally computes referential dependencies. The third contribution is a novel code differencing technique for diffing commits. This last contribution, called HyperDiff, complements HyperAST to compare commits at scale

Texto completoCompanies attach great importance to identifying automated and replicable approaches to solving their problems. This observation also applies to the software architecture renovation process. Within a large company, we joined the team in charge of renovating the software architecture. We studied the informal approach followed by this team in order to propose a generalization and tools facilitating its automation and its replication to other projects. Most of the solutions proposed in the literature cannot be applied to this project because of their manual nature, their particular constraints or their lack of application to real cases. However, we have identified that the Reflexion Model, information retrieval and statistical grouping may apply. We then proposed a new structured approach based on an adaptation of the Reflexion Model and on the approach developed by the company. Our approach uses five criteria to allocate existing source code to the architecture of the renovated software. We have shown that the application of our allocation criteria gives satisfactory results as opposed to seeking information and grouping. Finally, to meet the need for automation, we have defined what we call operators. They are based on the activities we have identified in the work of the company's engineers. We have shown that these operators would allow us to fully replicate our structured approach, thus allowing its effective application on other projects

Texto completoCavalcante, Hora André. "Assessing and improving rules to support software evolution". Thesis, Lille 1, 2014. http://www.theses.fr/2014LIL10114/document.
Texto completoSoftware systems evolve by adding new features, fixing bugs or refactoring existing source code. During this process, some problems may occur causing evolving systems and their clients to be inconsistent or to fail, decreasing code quality. One solution to deal with such maintainability problems is the usage of rules to ensure consistency. These rules may be created by experts or extracted from source code repositories, which are commonly evaluated in small-scale case studies. We argue that existing approaches lack of: (i) a deep understanding of the benefits provided by expert-based rules, (ii) a better use of source code repositories to extract history-based rules, and (iii) a large-scale analysis of the impact of source code evolution on the actual clients.In this thesis we propose to analyze and improve rules to better support developers keeping track of source code evolution. We cover three aspects: - The benefits provided by expert-based rules: we report on an investigation of rules created based on expert opinion to understand whether they are worthwhile to be adopted given the cost to produce them.- The improvement of history-based rules: we propose two solutions to extract better rules from source code history.- The impact of source code evolution on a software ecosystem: we undergo an investigation, in a large-scale ecosystem, on the awareness of the client systems about source code evolution. We evaluated the proposed approaches qualitatively and quantitatively. The results we obtained demonstrate the usefulness of our approaches

Texto completoNotre travail consiste en l’analyse et l’optimisation du code source d’applications de type système hérité (ou legacy system). Nous avons particulièrement travaillé sur un logiciel, appelé GP3, qui est développé et maintenu par la société de finances Sungard. Ce logiciel existe depuis plus d’une vingtaine d’années, il est écrit en un langage propriétaire, procédural et de 4ème génération, appelé ADL (ou Application Development Language). Ce logiciel à été initialement développé sous VMS et accédait à des bases de données d’ancienne génération. Pour des raisons commerciales, il fut porté sous UNIX et s’adresse maintenant à des SGBD-R de nouvelles génération ; Oracle et Sybase. Il a également été étendu de manière à offrir une interface web. Ce système hérité doit maintenant faire face à de nouveaux défis, comme la croissance de la taille des bases de données. Durant ces 20 dernières années, nous avons pu observer la fusion de plusieurs entreprises, ce qui implique la fusion de bases de données. Ces dernières peuvent dépasser les 1 Téra de données et plus encore sont à prévoir à l’avenir. Dans ce nouveau contexte, le langage ADL montre des limites à traiter une aussi importante masse de données. Des patterns de code, désignant des structures d’accès en base, sont suspectés d’être responsables de dégradations des performances. Notre travail consiste à détecter toutes les instances de patterns dans le code source, puis d’identifier les instances les plus consommatrices en temps d’exécution et en nombre d’appels. Nous avons développé un premier outil, nommé Adlmap, basé sur l’analyse statique de code, et qui permet de détecter toutes les accès en base dans le code source. Les accès en base identifiés comme patterns de code sont marqués. Le second outil que nous avons développé, nommé Pmonitor, est basé sur une analyse hybride ; combinaison d’analyses statique et dynamique. Cet outil nous permet de mesurer les performances des patterns de code et ainsi, d’identifier les instances les moins performantes
Durieux, Thomas. "From runtime failures to patches : study of patch generation in production". Thesis, Lille 1, 2018. http://www.theses.fr/2018LIL1I037/document.
Texto completoPatch creation is one of the most important actions in the life cycle of an application. Creating patches is a really time-consuming task. Not only because it is difficult to create a good and valid patch, but also because it requires the intervention of humans. Indeed, a user must report the bug and a developer must reproduce it and fix it, which takes a lot of time. To address this problem, techniques that automate this task have been created but those techniques still require a developer to create a test that reproduces the bug. This requirement drastically reduces the applicability of the approach since it still relies on the human. This thesis proposes new patch generation techniques that remove the human intervention for the generation of patches. Our idea is to put as close as possible the generation of patches to the production environment. We adopt this approach because the production environment contains all the data and human interactions that lead to the bug. During this thesis, we present how to exploit this data to detect bugs, generate and validate patches without the intervention of developers. We evaluate this approach on seven different benchmarks of real bugs collected from open-source projects. During the evaluation, we are particularly attentive to the number of generated patches, the correctness and the readability of the generated patches and the time required for generating them. Our evaluation shows the applicability and feasibility of our approach to generate patches in the production environment without the intervention of a developer

Texto completoThe existence of several copies of a same code fragment—called code clones in the literature—in a software can complicate its maintenance and evolution. Code duplication can lead to consistencyproblems, especially during bug fixes propagation. Code clone detection is therefore a majorconcern to maintain and improve software quality, which is an essential property for a software’ssuccess.The general objective of this thesis is to contribute to the use of code clone detection in softwaremaintenance tasks. We chose to focus our contributions on two research topics. Firstly, themethodology to compare and assess code clone detectors, i.e. clone benchmarks. We perform anempirical assessment of a clone benchmark and we found that results derived from this latter arenot reliable. We also identified recommendations to construct more reliable clone benchmarks.Secondly, the adaptation of code clone detectors in software maintenance tasks. We developed aspecialized approach in one language and one task—refactoring—allowing developers to identifyand remove code duplication in their softwares. We conducted case studies with domain experts toevaluate our approach
Abou, Khalil Zeinab. "Understanding the impact of release policies on software development processes". Thesis, Lille, 2021. http://www.theses.fr/2021LILUI011.
Texto completoThe advent of delivering new features faster has led many software projects to change their development processes towards more rapid release models where releases are shipped using release cycles of weeks or days. The adoption of rapid release practices has significantly reduced the amount of stabilization time, the time it takes for a software product’s failure rate to reach close to the steady-state, available for new features. This forces organizations to change their development process and tools to release to the public, in a timely manner and with good quality. Rapid releases are claimed to offer a reduced time-to-market and faster user feedback; end-users bene- fit of faster access to functionality improvements and security updates and improve turnaround time for fixing bad bugs. Despite these benefits, previous research has shown that rapid releases often come at the expense of reduced software reliability. Despite the increasing adoption of rapid releases in open-source and commercial soft- ware, the effects of this practice on the software development process are not well understood.The goal of this thesis is to provide a deeper understanding of how rapid releases impact different parts of the open-source software development process. We present empirical evidence about the short and long-term impact of rapid releases on the bug handling and testing process in open source organizations; and the plan and tools that are needed for successful adoption of rapid releases. This thesis presents an empirical case study of rapid releases in Eclipse and Mozilla Firefox projects. We follow a mixed-methods approach where we analyze software repositories, containing different types of data such as source code, testing data and software issues; and we conduct a survey with Eclipse developers. This help in understanding the evolution and changes of the software development process, the plans and practices that are needed for successful adoption of rapid releases and we identify several future research directions calling for further investigation
Uquillas, Gómez Verónica Isabel. "Supporting integration activities in object-oriented applications". Thesis, Lille 1, 2012. http://www.theses.fr/2012LIL10196/document.
Texto completoDevelopers deal with the integration of source code changes into the system release. Automatic and advanced merging techniques help them to merge their modifications. While these techniques help to merge changes, they do not guarantee to have a functional system, and they do not support performing cherry picking. Current state-of-the-art consists mostly of textual diff tools that do not provide an overview of the changes (how changes are distributed? what groups of entities did change?). At the same time, existing tools do not offer the possibility to understand changes within their specific context. Developers need to manually read the changed code, check the diffs to build an idea of a change, understand its context and assess its impact. This can be more complicated when developing large systems and the integration of streams of changes between branches is needed. Merging changes does not take into account the program entities they affect or their dependencies. Developers are responsible for performing manual and tedious comparison within the input stream of changes and also with their originating source. This dissertation presents a solution that supports the integration activities, such as aiding in understanding changes within a commit or within a stream of changes. We propose a first-class representation of the source code history and changes of a software system to enable the calculation of dependencies between changes. This combined with visual tool support for characterizing changes and dependencies, makes it possible to provide encompassing support for software integration aiding developers in understanding changes and guiding them during the merging processes

Texto completoSoftware depend on third-party libraries to reduce development and maintenance costs. Developers have access to robust functionalities through an application programming interface designed by these libraries. However, due to the strong relationship with these libraries, developers have to reconsider their position when the software evolves. In this thesis, we identify several re-search problems involving these third-party libraries in a context of software maintenance. More specifically, a library may not satisfy the software new requirements and has to be replaced by anew one. We call this operation a library migration.We leverage three points that characterize the impediments met by developers in this situation.To which library should they migrate ? How to migrate their software ? Who can help them in this case ? This thesis suggests answers and exposes several contributions to these problems. We define three approaches that are evaluated through several case studies. To achieve this work, weuse a methodology based on software evolution analysis to observe and understand how software change. We describe numerous perspectives to overcome the current limitations of our solutions

Texto completoDe, Souza Santos Gustavo Jansen. "Assessing and improving code transformations to support software evolution". Thesis, Lille 1, 2017. http://www.theses.fr/2017LIL10034/document.
Texto completoIn software development, change is the only constant. Software systems sometimes evolve in a substantial way and, during this process, sequences of code transformations (e.g., create a class, then override a method) are systematically performed in the system (e.g., to some classes in the same hierarchy). Due to the repetitive nature of these transformations, some automated support is needed to ensure that these sequences of transformations are consistently applied to the entire system.In this thesis we propose to improve source code transformations to better sup- port developers performing more complex and systematic code transformations. We cover two aspects: • The automated support to compose and apply sequences of code transformations. We undergo an investigation on the existence of these sequences in real-world software systems. We propose a tool to automatically apply these sequences in the systems we analyzed. • The detection of design violations during a transformation effort. We undergo an investigation on cases of systematic application of refactoring transformations. We proposed a tool that recommends additional transformations to fix design violations that are detected after performing refactoring transformations.We evaluated the proposed approaches quantitatively and qualitatively in real-world case studies and, in some cases, with the help of experts on the systems under analysis. The results we obtained demonstrate the usefulness of our approaches
Mordal, Karine. "Analyse et conception d'un modèle de qualité logiciel". Paris 8, 2012. http://www.theses.fr/2012PA084030.
Texto completoWe present a model and prototype for analysis and assess quality of large size industrial software, Squash model based on the empirical model developed by Qualixo and Air France-KLM enterprises. We determine an evaluation methodology for both technical and functional quality principles. Then we formalized a quality model taking into account the industrial applications requirements from this methodology. The implementation of this model is being validated by Generali. From the domain of software development and functional validation, we have formalized a model based on hierarchical quality models from standards ISO 9126 and Square. This model is divided into two levels: the conceptual quality level that defines the main quality principles and the technical quality that defines basic technical rules and measures used to assess the top level. The main issue of quality model conception is how to bring the gap between metrics and quality principles : the metrics meannig often defined for individual components cannot be easily transposed to higher abstraction levels. Furthermore, we need to highlight problems and do not hide progress. To achieve this, we use combinaison and aggregation formulas to asses quality principles from metrics and fuzzy logic to assess quality principles from non-metric measurements
Lelli, leitao Valeria. "Testing and maintenance of graphical user interfaces". Thesis, Rennes, INSA, 2015. http://www.theses.fr/2015ISAR0022/document.
Texto completoThe software engineering community takes special attention to the quality and the reliability of software systems. Software testing techniques have been developed to find errors in code. Software quality criteria and measurement techniques have also been assessed to detect error-prone code. In this thesis, we argue that the same attention has to be investigated on the quality and reliability of GUIs, from a software engineering point of view. We specifically make two contributions on this topic. First, GUIs can be affected by errors stemming from development mistakes. The first contribution of this thesis is a fault model that identifies and classifies GUI faults. We show that GUI faults are diverse and imply different testing techniques to be detected. Second, like any code artifact GUI code should be analyzed statically to detect implementation defects and design smells. As for the second contribution, we focus on design smells that can affect GUIs specifically. We identify and characterize a new type of design smell, called Blob listener. It occurs when a GUI listener, that gathers events to treat and transform as commands, can produce more than one command. We propose a systematic static code analysis procedure that searches for Blob listener that we implement in a tool called InspectorGuidget. Experiments we conducted exhibits positive results regarding the ability of InspectorGuidget in detecting Blob listeners. To counteract the use of Blob listeners, we propose good coding practices regarding the development of GUI listeners
Dias, Victor. "Supporting software integration activities with first-class code changes". Thesis, Lille 1, 2015. http://www.theses.fr/2015LIL10101/document.
Texto completoDevelopers typically change codebases in parallel from each other, which results in diverging codebases. Such diverging codebases must be integrated when finished. Integrating diverging codebases involves difficult activities. For example, two changes that are correct independently can introduce subtle bugs when integrated together. Integration can be difficult with existing tools, which, instead of dealing with the evolution of the actual program entities being changed, handle code changes as lines of text in files. Tools are important: software development tools have greatly improved from generic text editors to IDEs by providing high-level code manipulation such as automatic refactorings and code completion. This improvement was possible by the reification of program entities. Nevertheless, integration tools did not benefit from a similar reification of change entities to improve productivity in integration. In this work we first conducted a study to learn which integration activities are important and have little tool support. We discovered that one of such activities is the detection of tangled commits (that contain unrelated tasks such as a bug fix and a refactoring). Then we proposed Epicea, a reified change model and associated IDE tools, and EpiceaUntangler, an approach to help developers share untangled commits based on Epicea. The results of our evaluations with real-world studies show the usefulness of our approaches

Texto completoIn this thesis, I present the application of software engineering methods and knowledge to the development, maintenance, and evolution of Coq —an interactive proof assistant based on type theory— and its package ecosystem. Coq has been developed at Inria since 1984, but has only more recently seen a surge in its user base, which leads to much stronger concerns about its maintainability, and the involvement of external contributors in the evolution of both Coq, and its ecosystem of plugins and libraries.Recent years have seen important changes in the development processes of Coq, of which I have been a witness and an actor (adoption of GitHub as a development platform, first for its pull request mechanism, then for its bug tracker, adoption of continuous integration, switch to shorter release cycles, increased involvement of external contributors in the open source development and maintenance process). The contributions of this thesis include a historical description of these changes, the refinement of existing processes, and the design of new ones, the design and implementation of new tools to help the application of these processes, and the validation of these changes through rigorous empirical evaluation.Involving external contributors is also very useful at the level of the package ecosystem. This thesis additionally contains an analysis of package distribution methods, and a focus on the problem of the long-term maintenance of single-maintainer packages

Texto completoHabchi, Sarra. "Understanding mobile-specific code smells". Thesis, Lille 1, 2019. http://www.theses.fr/2019LIL1I089.
Texto completoObject-Oriented code smells are well-known concepts in software engineering. They refer to bad design and development practices commonly observed in software systems. With the emergence of mobile apps, new classes of code smells have been identified to refer to bad development practices that are specific to mobile platforms. These mobile-specific code smells differ from object-oriented ones by focusing on performance issues reported in the documentation or developer guidelines. Since their identification, many research works approached mobile-specific code smells to propose detection tools and study them. Nonetheless, most of these studies only focused on measuring the performance impact of such code smells and did not provide any insights about their motives and potential solutions. In particular, we lack knowledge about (i) the rationales behind the accrual of mobile code smells, (ii) the developers’ perception of mobile code smells, and (iii) the generalizability of code smells across different mobile platforms. These lacks hinder the understanding of mobile code smells and consequently prevent the design of adequate solutions for them. Therefore, we conduct in this thesis a series of empirical studies with the aim of understanding mobile code smells. First, we study the expansion of code smells in different mobile platforms. Then, we conduct a large-scale study to analyze the change history of mobile apps and discern the factors that favor the introduction and survival of code smells. To consolidate these studies, we also perform a user study to investigate developers’ perception of code smells and the adequacy of static analyzers as a solution for coping with them. Finally, we perform a qualitative study to question the established foundation about the definition and detection of mobile code smells. The results of these studies revealed important research findings. Notably, we showed that pragmatism, prioritization, and individual attitudes are not relevant factors for the accrual of mobile code smells. The problem is rather caused by ignorance and oversight, which are prevalent among mobile developers. Furthermore, we highlighted several flaws in the code smell definitions that are currently adopted by the research community. These results allowed us to elaborate some recommendations for researchers and tool makers willing to design detection and refactoring tools for mobile code smells. On top of that, our results opened perspectives for research works about the identification of mobile code smells and development practices in general

Texto completoThe software evolution control requires a complete understanding of the changes and their impact on the various systems artifacts. We propose a multi-modeling approach for the change impact analysis to provide assistance in understanding the effects of projected or actual changes in distributed software systems. This work elaborate the modeling of software artifacts along with their various interdependencies to build a knowledge-based system, which allows, among others, an assistance for the software developers or maintenance engineers to establish an a priori evaluation of impact of changes. The model we develop integrates two major descriptions of software, at first, the underlying structural description that encompasses the levels of granularity and abstraction of software artifacts, and then the qualitative description designed to integrate the structural description. Initially, the formal models are designed separately for the respective descriptions, and then these are integrated for the objective to study the change impact and its potential propagation through the affected software artifacts. For a change, it is important to establish a qualitative assessment of its impact. The integrated modeling leads to a reasoning based on expert rules. The proposed model is being tested and validated through the development of a platform, implemented in the Eclipse environment

Texto completoThe increasing use of the Web as a software platform together with the advance of technology has promoted Web applications as a start point for delivering information and services. Facing to the ever growing number of users, usability became a major requirement for the universal access of Web applications. In the last years, a number of evaluation methods have been developed by researchers, practitioners and Information Technology companies to help organizations to identify and to fix usability problems. However, usability evaluation of Web sites is not a straightforward process. On one hand, usability evaluation requires some knowledge and expertise in software ergonomics. One the other hand, due to constant evolution of Web application, it is required frequent evaluations to make sure that content updates do not introduce new usability problems. In order to overcome these limitations, much effort has been devoted in the development of tools for automating the inspection of usability and accessibility guidelines. However, tools currently available can only evaluate the final applications. In this thesis we propose a model-based evaluation method that allows ensuring the ergonomic quality of Web applications throughout the lifecycle. .

Developers also benefit from dynamic modifications of software by adapting code to new unanticipated situations or by running dynamic analyses to get feedback about the behavior of running applications for monitoring, debugging and optimization purposes. Programming languages should thus provides developers with mechanisms that improve software adaptability. At the same time, the increasing size and complexity of software call for applications made up of many interacting components developed by different parties. In this context, each component needs to be properly protected from other ones. Programming languages should thus provide developers with mechanisms that improve encapsulation. The need for dynamic adaptations on the one hand and the need for properly confined components on the other hand pulls programming language design in two opposite directions: either more flexi-bility or more control.This dissertation studies this tension in the context of dynamically-typed object-oriented languages with two language mechanisms that promote software adaptability: reflection and extension meth-ods. For both mechanisms, we demonstrate their usefulness, their harmful effect on encapsulation and propose solutions to retain their power while maintaining encapsulation

Texto completoMobile applications are becoming complex software systems that must be developed quickly and evolve continuously to fit new user requirements and execution contexts. However, addressing these constraints may result in poor low-level design choices, known as code smells. The presence of code smells within software systems may incidentally degrade their quality and performance, and hinder their maintenance and evolution. Thus, it is important to know this smells but also to detect and correct them. While code smells are well-known in object-oriented applications, their study in mobile applications is still in their infancy. Moreover there is a lack of tools to detect and correct them. That is why we present a classification of 17 code smells that may appear in Android applications, as well as a tool to detect and correct code smells on Android. We apply and validate our approach on large amounts of applications (over 3000) in two studies evaluating the presence and evolution of the number of code smells in popular applications. In addition, we also present two approaches to assess the impact of the correction of code smells on performance and energy consumption. These approaches have allowed us to observe that the correction of code smells is beneficial in most cases

Texto completoWorldline, a major IT company, has to increase the quality of its projects. We performed an audit of several projects of the company to identify how to avoid project failure: no final conclusion has been drawn. However, it highlighted a need to enhance testing usage. To test every piece of code is compulsory to avoid project failure. In industry and more specifically in Worldline, automation of tests has begun to ensure the proper behavior of their applications. But, ensuring the execution of all tests after a change can be a costly operation requiring several hours. Feedback on the changed code is delayed and developer has to spent time to discover the potential bugs. The solution generally proposed in literature consists in reducing the number of tests to run by selecting only the ones related to the last changes made by the developer. The approach selects a suitable and small set of tests to detect potential regression in the application behavior.These approaches need to be studied in the context of Worldline and consequently adapted to suit developers’ habits. Before integrating such an adapted test selection approach, a study of the testing behavior of the developers has been done to get their current test selection usage. Based on the study of the Worldline environment, we developed a tool for the developers aiming to perform test selection.The goal is also to study the impact of this tool on their behavior. We hope that the test selection approach that is packaged in a tool adapted to the Worldline developers will bring a change in their developmentprocess

Texto completoWith the expansion of Internet of Things (IoT) that relies on heterogeneous; dynamic; and massively deployed devices; Device Management (DM), which consists of firmware update, configuration, troubleshooting and tracking, is required for proper quality of service and user experience, deployment of new functions, bug fixes and distribution of security patches.Existing Home and IoT industrial DM platforms are already showing their limits with a few static home and IoT devices (e.g., routers, TV Decoders). Currently, these platforms are mainly manually operated by experts such as system administrators, and require extensive knowledge and skills. Heterogeneity implies that devices have diverse compute and network capabilities. Dynamicity translates to variation of devices environments (e.g., network quality, running services, nearby devices). The massive aspect is reflected in fleets composed of billions of devices as opposed to millions currently.Therefore, IoT device administration requires launching administration operations that assure the well-functioning of device fleets. These operations are to be adapted in terms of nature, speed, target, accordingly to devices current service requirements, computing capabilities and network conditions. Existing manually operated approaches cannot be applied on these massive and diverse devices forming the IoT.To tackle these issues, our work in an industrial research context, at Orange Labs, proposes applying autonomic computing to platform operation and distribution. It aims to ensure that administration requirements of a device fleet are automatically fulfilled using the optimal amount of resources and with the least amount of execution errors.Specifically, our contribution relies on four coordinated autonomic loops. The first two loops are responsible for handling fleet variation and update operations dispatching, while the remaining two others focus on vertical and horizontal scalability. Our approach allows automatic administration platform operation, more accurate and faster error diagnosis, vertical and horizontal scaling along with simpler IoT DM platform administration.For experimental validation, we developed two prototypes: one that demonstrates the usability of our approach with Orange's industrial IoT platform for its piloting, while the other one demonstrates vertical scalability using extended open-source remote administration software. Our prototypes show encouraging results, such as two times faster firmware upgrade operation execution speed, compared to existing legacy telecommunication operator approaches

Texto completoDes techniques et outils ont été proposés dans la littérature à la fois pour la détection et la correction des défauts. Les techniques de détection proposées consistent principalement à définir des règles pour détecter les défauts et à les appliquer sur le code source d'un système. Quant aux techniques de correction, elles consistent à appliquer de façon automatique des refactorisations dans le code source du système analysé afin de le restructurer de manière à corriger les défauts. Cependant, la phase qui consiste à identifier les restructurations est réalisée manuellement par les
ingénieurs logiciels. Ainsi, il n'est pas possible de corriger
directement et automatiquement les défauts détectés. Ce problème est dû au fait que la détection et la correction des défauts sont traitées de façon isolée.
Ainsi, nous proposons DECOR, une méthode qui englobe et définit toutes les étapes nécessaires pour la détection et la correction des défauts de code et de conception. Cette méthode permet de spécifier des règles de détection à un haut niveau d'abstraction et de suggérer des restructurations de code afin d'automatiser la correction des défauts.
Nous appliquons et validons notre méthode sur des systèmes libres orientés objet afin de montrer que notre méthode permet une détection précise et une correction adaptée des défauts.

Texto completoWith the development of new information and communication technologies, working procedures are increasingly computerized. This increasing computerization of working procedures raises the question of their acceptance by workers who have to appropriate new ways of doing their work. The present thesis aims to examine the conditions for the adoption of technologies conveying work procedures by maintenance technicians. Four studies are carried out on two fields of research (aeronautical maintenance and industrial maintenance) with the aim of understanding how maintenance technicians perceive and use these computerized working procedures. Two studies are carried out in the field of aeronautics and aim to investigate the social acceptability and the use of three new formats of procedures (3D animation, 2D and photos) before they are set up in the workshops. Study 1 examines the perception of new procedure formats by technicians (N = 136). The results of this study show that beliefs related to usefulness and ease of use are the main predictors of behavioral intention. In addition, it appears that beliefs differ depending on the type of use behavior of the procedures (daily or exceptional use). In order to understand the possible difficulties in using these new formats, Study 2 concerns the realization of user tests (N = 41). The aim is to study the usefulness and usability of the new procedural formats compared to the current format (text + image). The results show that all technicians succeed in maintenance, regardless of the format used. In addition, in general, new formats allow technicians to be more efficient because they take less time with new formats (3D animation and photos) than with reference formats and so errors made during maintenance are reduced. The new formats, with the presence of visual information, facilitate the location of the information on the equipment. Finally, a large majority of technicians intend to use the new formats. Two other studies are carried out in the field of industrial maintenance on the acceptance and use of a management of procedures software by the technicians. In this framework, study 3 concerns the perception of software in use by maintenance technicians (N = 61). The results highlight the belief in perceived compatibility as the main predictor of attitude, behavioral intention, and actual use of the software. In order to investigate the actual use of the software, study 4 deals with the analysis of the activity of 8 technicians from four workshops (filmed observation and interview). The results show that the software is suitable for only some of the technicians. Indeed, it seems to represent a brake for experienced technicians and moderately experienced technicians in the sense they are constrained in the use of the software (impossibility to navigate freely between the steps). However, the software proves to be a valuable help for inexperienced technicians (help support, training aid ...). Recommendations are made to improve the design of the software studied. In particular, improvements in the design of the three new formats of aeronautical maintenance procedures are suggested (adapting the format to the task carried out, improving the ergonomics of the touch pad...). In the second case, we make recommendations to modify the procedure management software and make it more compatible with the work of the technicians (setting up an expert mode, facilitating the search for information, navigating freely between steps …)

Texto completoThis cost minimization must be preceeded by a diagnostic that allows to measure the effort required by a good quality and recommends actions to undertake. Many tools have been developed to obtain a quantitative view on software quality. However, much work remains to be done. Our research belongs to that stream of research. We show the limits of metrics and propose an expert system approach that allows to cover both syntactic and semantic aspects of software. Besides the software quality evaluation, the system helps to improve this quality by emphasizing the most penalizing quality criteria for the program under review. Given this information, programs could be graded and their maintenance cost reduced so that human ressources could develop new applications. In addition, an important work of collection of metrics and elaboration of quality checklists has been done
