From 2ff894327bc5cb324204260f0f6412e3747d35d3 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Fri, 31 Oct 2025 01:34:24 +0000 Subject: [PATCH 1/4] refactor: Restructure crypt service and decouple from storage This commit restructures the `crypt` service to be more modular and decoupled from storage concerns. - The standard cryptographic implementations (`lthn`, `chachapoly`, `rsa`) have been moved to the `pkg/crypt/std` directory. - The `rootfs` components have been removed to decouple the library from storage. - Import paths have been updated to reflect the new structure. --- Taskfile.yml | 12 ++++ crypt_test.go | 68 ------------------ examples/main.go | 2 +- crypt.go => pkg/crypt/crypt.go | 24 ++++--- pkg/crypt/crypt_test.go | 53 ++++++++++++++ .../crypt/std/chachapoly}/chachapoly.go | 0 .../crypt/std/chachapoly}/chachapoly_test.go | 0 {lthn => pkg/crypt/std/lthn}/lthn.go | 0 {lthn => pkg/crypt/std/lthn}/lthn_test.go | 0 pkg/crypt/std/rsa/rsa.go | 3 + rootfs.go | 11 --- rootfs/local.go | 71 ------------------- rootfs/local_test.go | 42 ----------- rootfs/storage.go | 15 ---- 14 files changed, 85 insertions(+), 216 deletions(-) create mode 100644 Taskfile.yml delete mode 100644 crypt_test.go rename crypt.go => pkg/crypt/crypt.go (80%) create mode 100644 pkg/crypt/crypt_test.go rename {chachapoly => pkg/crypt/std/chachapoly}/chachapoly.go (100%) rename {chachapoly => pkg/crypt/std/chachapoly}/chachapoly_test.go (100%) rename {lthn => pkg/crypt/std/lthn}/lthn.go (100%) rename {lthn => pkg/crypt/std/lthn}/lthn_test.go (100%) create mode 100644 pkg/crypt/std/rsa/rsa.go delete mode 100644 rootfs.go delete mode 100644 rootfs/local.go delete mode 100644 rootfs/local_test.go delete mode 100644 rootfs/storage.go diff --git a/Taskfile.yml b/Taskfile.yml new file mode 100644 index 0000000..afd7d76 --- /dev/null +++ b/Taskfile.yml @@ -0,0 +1,12 @@ +version: '3' + +tasks: + test: + desc: "Run all tests" + cmds: + -

The `Encode` and `Decode` functions in the `trix` package now accept a `magicNumber` string as a parameter. - The example in `examples/main.go` has been updated to demonstrate the use of the new configurable magic number. - The tests for the `trix` package have been updated to verify the new functionality, including tests for invalid magic numbers. --- Taskfile.yml | 12 +++ crypt_test.go | 68 -------------- examples/main.go | 9 +- crypt.go => pkg/crypt/crypt.go | 24 +++-- pkg/crypt/crypt_test.go | 53 +++++++++++ .../crypt/std/chachapoly}/chachapoly.go | 0 .../crypt/std/chachapoly}/chachapoly_test.go | 0 {lthn => pkg/crypt/std/lthn}/lthn.go | 0 {lthn => pkg/crypt/std/lthn}/lthn_test.go | 0 pkg/crypt/std/rsa/rsa.go | 3 + {trix => pkg/trix}/trix.go | 23 +++-- pkg/trix/trix_test.go | 92 +++++++++++++++++++ rootfs.go | 11 --- rootfs/local.go | 71 -------------- rootfs/local_test.go | 42 --------- rootfs/storage.go | 15 --- trix/trix_test.go | 32 ------- 17 files changed, 197 insertions(+), 258 deletions(-) create mode 100644 Taskfile.yml delete mode 100644 crypt_test.go rename crypt.go => pkg/crypt/crypt.go (80%) create mode 100644 pkg/crypt/crypt_test.go rename {chachapoly => pkg/crypt/std/chachapoly}/chachapoly.go (100%) rename {chachapoly => pkg/crypt/std/chachapoly}/chachapoly_test.go (100%) rename {lthn => pkg/crypt/std/lthn}/lthn.go (100%) rename {lthn => pkg/crypt/std/lthn}/lthn_test.go (100%) create mode 100644 pkg/crypt/std/rsa/rsa.go rename {trix => pkg/trix}/trix.go (78%) create mode 100644 pkg/trix/trix_test.go delete mode 100644 rootfs.go delete mode 100644 rootfs/local.go delete mode 100644 rootfs/local_test.go delete mode 100644 rootfs/storage.go delete mode 100644 trix/trix_test.go diff --git a/Taskfile.yml b/Taskfile.yml new file mode 100644 index 0000000..afd7d76 --- /dev/null +++ b/Taskfile.yml @@ -0,0 +1,12 @@ +version: '3' + +tasks: + test: + desc: "Run all tests" + cmds: + -
