Git Repository Indexing and Viewing Service

This work is devoted to the implementation of a service for indexing Git repositories, which provides functionality for navigating through the source codes of the repository with the ability to find the definition of certain symbols or all their uses. First, a comparison with existing similar solutions is given, problems are formulated and a list of requirements for the system being implemented. Then the text suggests solutions to the problems posed and provides specific methods for obtaining and storing source texts from Git repositories, for obtaining semantic data and for effectively forming a response to queries using LSIF technology, as well as a method for versioning data to store different versions of the repository in one database. In particular, it describes a mechanism for quickly obtaining semantic data at the expense of their accuracy, using information from earlier indexed versions of the repository. Finally, this document provides details of the system implementation: the overall architecture, the technologies used, a description of the data model and descriptions of individual services, as well as protocols for their interaction with each other.
