Sustaining open source (OS) communities is fundamental to the long-term success of any open source software (OSS) project. An OSS project consists of a community of software developers who are part of a larger business ecosystem involving hardware and software companies. Peer review of software code, known as patch review comments, is an important quality assurance activity for OSS development that requires developers to provide feedback concerning their degree of satisfaction. Despite the importance of feedback, which can affect sentiment of OS communities, the underlying discourse has not been studied. In this study, we use Activity Theory to identify and categorise 20,651 discursive manifestations of contradictions that occurred in patch review comments of a large, evolving OS community. Unique community-specific expressions are identified and mapped to developers’ sentiment during a software release cycle. The study contributes new insights concerning discursive manifestations of contradictions as a driving force for sustaining OS communities.

维持开源（OS）社区对于任何开源软件（OSS）项目的长期成功都是至关重要的。OSS项目由软件开发人员社区组成，这些软件开发人员是包含硬件和软件公司的大型业务生态系统的一部分。对软件代码的同行评审（称为补丁评审注释）是OSS开发中一项重要的质量保证活动，要求开发人员提供有关其满意程度的反馈。尽管反馈的重要性可能会影响OS社区的情绪，但尚未研究基本的论述。在这项研究中，我们使用活动理论来识别和分类在大型的不断发展的OS社区的补丁评论中出现的20,651个矛盾的矛盾表现形式。在软件发布周期中，将识别特定于社区的独特表达并将其映射到开发人员的情绪。这项研究为矛盾的话语表现形式提供了新的见解，这些话语是维持OS社区的驱动力。
