+ [talk/robert2017](https://www.youtube.com/watch?v=KPk1UPihWtY)Summary: In the opening keynote of GopherCon SG 2017, Robert Griesemer discusses the Go programming language and its use of packages to divide large projects. He compares the export and import mechanism of packages to the simpler times of the 1970s when C was invented. Griesemer highlights the importance of using header files in creating a library in C, as they allow for the explicit declaration of library interfaces, making it easier for the C compiler to compile the program. However, he also acknowledges the limitations and challenges of using header files, such as information leakage and potential performance issues in large systems. Griesemer explains that package serialization is important in programming languages as it allows the compiler to understand and communicate imported packages. He discusses the process of compiling Go packages and the need for serialization, as well as the use of dot o and dot a files for exporting and importing data. He mentions that object files can be read using a text editor and explains the structure and content of a pre-1. 7 compiler object file, which includes redundant and unnecessary information. To address these issues, Griesemer explains that a binary export format was adopted, which is more compact and efficient. The new format also includes additional information and allows for easy extension without a full-fledged parser. He discusses the serialization of package interfaces in Go, which involves representing the internal data structure as a graph. Griesemer explains a serialization algorithm in Go that can be used for any graph data structure, involving assigning unique integer values to nodes and writing out their content. Griesemer emphasizes the need to efficiently process export data by re-engineering it for indexing, reducing processing waste. He discusses the differences between textual and binary export formats, with the binary format being more space-efficient. However, challenges remain in processing only required fields. Griesemer suggests re-engineering export data to make it indexable for more efficient access, especially for large data structures like protocol buffers. Overall, Griesemer's keynote provides insights into the inner workings of import and export mechanisms in Go, and how these mechanisms enable robust separate compilation of packages. He discusses the historical context of these mechanisms and the design trade-offs that affect scalability. The talk highlights the importance of package serialization and the challenges involved in creating efficient and compact export formats.
