Etcher currently elevates a child writer proxy that itself spawns the Etcher CLI in robot mode, parses the output, and proxies those messages to the GUI application over IPC. After these set of changes, Etcher elevates a single child writer process that directly communicates back with the GUI using IPC. The main purpose behind these changes is to simplify the overall architecture and fix various issues caused by the current complex child process tree. Here's a summary of the changes: - Stop wrapping the Etcher CLI to perform writing - Remove the robot option from the Etcher CLI (along with related documentation) - Elevate a new `child-write.js` standalone executable - Move the relevant bits of `lib/child-writer` to the `image-writer` GUI module - Remove the `lib/child-writer` directory - Add a new "Child died unexpectedly" Mixpanel event - Floor state percentage in the flash state model The above changes made is possible to tackle all the remaining issues where the writer process would remain alive even if the parent died. Change-Type: patch Changelog-Entry: Ensure the writer process dies when the GUI application is killed.
