From 682d9ff0ab23d9dcfe786684484d426a937ea2ac Mon Sep 17 00:00:00 2001 From: allure <1550220889@qq.com> Date: Sat, 23 Aug 2025 16:10:19 +0800 Subject: [PATCH 1/2] feat(libra): Add tagging functionality for objects MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit introduces the ability to add, remove, and list tags on objects within the libra module. It adds a new tag command and the corresponding internal logic for tag management. 此 PR 完成了 r2cn 测试任务 #1352 Signed-off-by: allure <1550220889@qq.com> --- .../contents/docs/libra/command/tag/index.mdx | 38 ++- common/src/utils.rs | 22 +- libra/src/cli.rs | 3 + libra/src/command/commit.rs | 7 +- libra/src/command/fetch.rs | 35 +-- libra/src/command/init.rs | 36 +-- libra/src/command/mod.rs | 38 +-- libra/src/command/rebase.rs | 10 +- libra/src/command/reflog.rs | 14 +- libra/src/command/tag.rs | 184 ++++++++++++++ libra/src/internal/db.rs | 26 +- libra/src/internal/mod.rs | 1 + libra/src/internal/protocol/https_client.rs | 25 +- libra/src/internal/reflog.rs | 2 +- libra/src/internal/tag.rs | 231 ++++++++++++++++++ libra/src/utils/util.rs | 78 +++++- libra/tests/command/fetch_test.rs | 1 + libra/tests/command/log_test.rs | 3 +- libra/tests/command/mod.rs | 2 +- libra/tests/command/switch_test.rs | 56 ++--- mega/tests/service_test.rs | 1 + mercury/src/errors.rs | 7 +- mercury/src/internal/model/tag.rs | 2 +- mercury/src/internal/object/commit.rs | 91 ++++--- mercury/src/internal/object/tag.rs | 128 ++++++---- 25 files changed, 785 insertions(+), 256 deletions(-) create mode 100644 libra/src/command/tag.rs create mode 100644 libra/src/internal/tag.rs diff --git a/aria/contents/docs/libra/command/tag/index.mdx b/aria/contents/docs/libra/command/tag/index.mdx index 524b11139..ebb87aa22 100644 --- a/aria/contents/docs/libra/command/tag/index.mdx +++ b/aria/contents/docs/libra/command/tag/index.mdx @@ -1,4 +1,40 @@ --- title: The [tag] Command -description: +description: Create, list, delete, or show tag objects --- + +### Usage + +libra tag [OPTIONS] [NAME] + +### Arguments + +- `[NAME]` + The name of the tag to create, show, or delete. + +### Description + +The `libra tag` command is used to manage tag objects.
