The --bounding-dirs flag and BoundingDirs field in deepcopy-gen are dead code. The field is stored on the genDeepCopy struct but never read by any method. The flag was introduced in gengo commit 14ae879 (2016) to control which types deepcopy would generate for and which nested types it could assume had generated deepcopy functions. Over time, as deepcopy-gen was rewritten (gengo v2, moved to code-generator), the copyableAndInBounds / isRootedUnder usage was dropped. The field and flag survived but g.boundingDirs is never referenced in the current code. hack/update-codegen.sh still passed --bounding-dirs but it had no effect.
Kubernetes hack GuideLines
This document describes how you can use the scripts from hack directory
and gives a brief introduction and explanation of these scripts.
Overview
The hack directory contains many scripts that ensure continuous development of kubernetes,
enhance the robustness of the code, improve development efficiency, etc.
The explanations and descriptions of these scripts are helpful for contributors.
For details, refer to the following guidelines.
Key scripts
verify-all.sh: This script is a vestigial redirection, Please do not add "real" logic. It is equivalent tomake verify.update-all.sh: This script is a vestigial redirection, Please do not add "real" logic. Thetruetarget of this makerule ishack/make-rules/update.sh.It is equivalent tomake update.
Attention
Note that all scripts must be run from the Kubernetes root directory.
We should run hack/verify-all.sh before submitting a PR and if anything fails run hack/update-all.sh.
