| // |
| // Steps on how to find which oldestSupportedSkpVersion to use: |
| // 1) Find the git hash when the desired kMin_Version was the kCurrent_Version from the |
| // git logs: https://skia.googlesource.com/skia/+log/main/src/core/SkPicturePriv.h |
| // Eg: https://skia.googlesource.com/skia/+/bfd330d081952424a93d51715653e4d1314d4822%5E%21/#F1 |
| // |
| // 2) Use that git hash to find the SKP asset version number at that time here: |
| // https://skia.googlesource.com/skia/+/bfd330d081952424a93d51715653e4d1314d4822/infra/bots/assets/skp/VERSION |
| // |
| // 3) [Optional] Increment the SKP asset version number from step 3 and verify that it has |
| // the expected version number by downloading the asset and running skpinfo on it. |
| // |
| // 4) Use the incremented SKP asset version number as the oldestSupportedSkpVersion in |
| // infra/bots/gen_tasks_logic/gen_tasks_logic.go |
| // |
| // 5) Run `make -C infra/bots train` |
| // |
| // Contact the Infra Gardener (or directly ping rmistry@) if the above steps do not work |
| // for you. |
