In this paper we present our solution: MetropolJS. By using a Treemap-based visualization it is possible to get a high level view within limited screen real estate. Previous approaches to Treemaps lacked the fine detail and interactive features to be useful as a debugging tool. This paper introduces an optimized approach for visualizing complex program structure that enables new debugging techniques where the execution of programs can be displayed in real time from a bird's-eye view. The approach facilitates highlighting and visualizing method calls and distinctive code patterns on top of code segments without a high overhead for navigation. Using this approach enables fast analysis of previously difficult-to-comprehend code bases.","PeriodicalId":348046,"journal":{"name":"Proceedings of the 26th Conference on Program Comprehension","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121117756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in reality, the source code of an application always interacts with many third-party libraries, which are often not easily accessible to static analyzers. Worse still, more than 30% of legacy projects cannot be compiled easily due to complicated configuration environments (e.g., third-party libraries, compiler options and macros), making ideal \"whole-program analysis\" unavailable in practice. This paper presents CoBOT, a static analysis tool that can detect bugs in the presence of incomplete code. It analyzes function APIs unavailable in application code by either using function summarization or automatically downloading and analyzing the corresponding library code as inferred from the application code and its configuration files. The experiments show that CoBOT is not only easy to use, but also effective in detecting bugs in real-world programs with incomplete code.

However, services may leak such that they are no longer used but cannot be recycled by the Garbage Collector. Service leaks may cause an app to misbehave, and are vulnerable to malicious external apps when the service is exported or it is accessible through other exported services. In this paper, we present LESDroid for exported service leaks detection. LESDroid automatically generates service instances and workloads (start/stop or bind/unbind of exported services) of the app under test, and applies a designated oracle to the heap snapshot for service leak detection. We evaluated LESDroid using 375 commercial apps, and found 97 leaked services and 98 distinct leak entries in 70 apps.","PeriodicalId":348046,"journal":{"name":"Proceedings of the 26th Conference on Program Comprehension","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127535770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In practice, researchers usually record execution traces and generate a sequence diagram according to them. However, the diagram can be too large to read while treating real-world software due to the massiveness of execution traces. Several studies on minimizing/compressing sequence diagrams have been proposed; however, the resulting diagram may be either still large or losing important information. Besides, existing tools are highly customized for a certain research purpose. To address these problems, we present a generic toolkit SDExplorer in this paper, which is a flexible and lightweight tool to effectively explore a massive-scale sequence diagram in a highly scalable manner. Additionally, SDExplorer supports popular features of existing tools (i.e. search, filter, grouping, etc.). We believe it is an easy-to-use and promising tool in future research to evaluate and compare the minimizing/compressing techniques in real maintenance tasks.","PeriodicalId":348046,"journal":{"name":"Proceedings of the 26th Conference on Program Comprehension","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116415558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, low levels of code readability perceived by developers still represent a barrier to their daily work. In this paper, we describe a survey that assessed the impact of a set of Java coding practices on the readability perceived by software developers. While some practices promoted an enhancement of readability, others did not show statistically significant effects. Interestingly, one of the practices worsened the readability. Our results may help to identify coding conventions with a positive impact on readability and, thus, guide the creation of coding standards.","PeriodicalId":348046,"journal":{"name":"Proceedings of the 26th Conference on Program Comprehension","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114258606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
