From cb7ba8969db3b6750221fa955e4e8b2968a7eaed Mon Sep 17 00:00:00 2001 From: oliverpool <3864879+oliverpool@users.noreply.github.com> Date: Fri, 12 May 2023 20:14:41 +0200 Subject: [PATCH] fix: release page for empty or non-existing target (#24659) Backport #24470 Fixes #24145 --- To solve the bug, I added a "computed" `TargetBehind` field to the `Release` model, which indicates the target branch of a release. This is particularly useful if the target branch was deleted in the meantime (or is empty). I also did a micro-optimization in `calReleaseNumCommitsBehind`. Instead of checking that a branch exists and then call `GetBranchCommit`, I immediately call `GetBranchCommit` and handle the `git.ErrNotExist` error. This optimization is covered by the added unit test. _contributed in the context of @forgejo_ --- models/fixtures/release.yml | 28 ++++++++++++++++++ models/repo/release.go | 1 + routers/web/repo/release.go | 34 ++++++++++++++-------- routers/web/repo/release_test.go | 47 +++++++++++++++++++++++++++++++ templates/repo/release/list.tmpl | 4 +-- tests/integration/release_test.go | 10 +++++-- 6 files changed, 107 insertions(+), 17 deletions(-) diff --git a/models/fixtures/release.yml b/models/fixtures/release.yml index 6d09401eb..4ed7df440 100644 --- a/models/fixtures/release.yml +++ b/models/fixtures/release.yml @@ -108,3 +108,31 @@ is_prerelease: false is_tag: false created_unix: 946684803 + +- id: 9 + repo_id: 57 + publisher_id: 2 + tag_name: "non-existing-target-branch" + lower_tag_name: "non-existing-target-branch" + target: "non-existing" + title: "non-existing-target-branch" + sha1: "cef06e48f2642cd0dc9597b4bea09f4b3f74aad6" + num_commits: 5 + is_draft: false + is_prerelease: false + is_tag: false + created_unix: 946684803 + +- id: 10 + repo_id: 57 + publisher_id: 2 + tag_name: "empty-target-branch" + lower_tag_name: "empty-target-branch" + target: "" + title: "empty-target-branch" + sha1: "cef06e48f2642cd0dc9597b4bea09f4b3f74aad6" + num_commits: 5 + is_draft: false + is_prerelease: false + is_tag: false + created_unix: 946684803 diff --git a/models/repo/release.go b/models/repo/release.go index abf91bc4b..73311da87 100644 --- a/models/repo/release.go +++ b/models/repo/release.go @@ -71,6 +71,7 @@ type Release struct { OriginalAuthorID int64 `xorm:"index"` LowerTagName string Target string + TargetBehind string `xorm:"-"` // to handle non-existing or empty target Title string Sha1 string `xorm:"VARCHAR(40)"` NumCommits int64 diff --git a/routers/web/repo/release.go b/routers/web/repo/release.go index 15b00c33e..f94f14166 100644 --- a/routers/web/repo/release.go +++ b/routers/web/repo/release.go @@ -5,6 +5,7 @@ package repo import ( + "errors" "fmt" "net/http" "strings" @@ -16,6 +17,7 @@ import ( user_model "code.gitea.io/gitea/models/user" "code.gitea.io/gitea/modules/base" "code.gitea.io/gitea/modules/context" + "code.gitea.io/gitea/modules/git" "code.gitea.io/gitea/modules/log" "code.gitea.io/gitea/modules/markup" "code.gitea.io/gitea/modules/markup/markdown" @@ -36,24 +38,32 @@ const ( // calReleaseNumCommitsBehind calculates given release has how many commits behind release target. func calReleaseNumCommitsBehind(repoCtx *context.Repository, release *repo_model.Release, countCache map[string]int64) error { - // Get count if not exists - if _, ok := countCache[release.Target];
