From c5901b622dd5fae8da336b94150e63292489afed Mon Sep 17 00:00:00 2001 From: wxiaoguang Date: Sun, 7 Jan 2024 18:20:22 +0800 Subject: [PATCH] Avoid unnecessary 500 panic when a commit doesn't exist (#28719) In #26851, it assumed that `Commit` always exists when `PageIsDiff==true`. But for a 404 page, the `Commit` doesn't exist, so the following code would cause panic because nil value can't be passed as string parameter to `IsMultilineCommitMessage(string)` (or the StringUtils.Cut in later PRs) --- templates/base/head_opengraph.tmpl | 2 +- tests/integration/repo_test.go | 10 ++++++++++ 2 files changed, 11 insertions(+), 1 deletion(-) diff --git a/templates/base/head_opengraph.tmpl b/templates/base/head_opengraph.tmpl index 19d924610..f1f38999d 100644 --- a/templates/base/head_opengraph.tmpl +++ b/templates/base/head_opengraph.tmpl @@ -17,7 +17,7 @@ {{else if or .PageIsDiff .IsViewFile}} - {{if .PageIsDiff}} + {{if and .PageIsDiff .Commit}} {{- $commitMessageParts := StringUtils.Cut .Commit.Message "\n" -}} {{- $commitMessageBody := index $commitMessageParts 1 -}} {{- if $commitMessageBody -}} diff --git a/tests/integration/repo_test.go b/tests/integration/repo_test.go index f5417b100..f141b6dcb 100644 --- a/tests/integration/repo_test.go +++ b/tests/integration/repo_test.go @@ -12,6 +12,7 @@ import ( "time" "code.gitea.io/gitea/modules/setting" + "code.gitea.io/gitea/modules/test" "code.gitea.io/gitea/tests" "github.com/PuerkitoBio/goquery" @@ -448,3 +449,12 @@ func TestGeneratedSourceLink(t *testing.T) { assert.Equal(t, "/user27/repo49/src/commit/aacbdfe9e1c4b47f60abe81849045fa4e96f1d75/test/test.txt", dataURL) }) } + +func TestViewCommit(t *testing.T) { + defer tests.PrepareTestEnv(t)() + + req := NewRequest(t, "GET", "/user2/repo1/commit/0123456789012345678901234567890123456789") + req.Header.Add("Accept", "text/html") + resp := MakeRequest(t, req, http.StatusNotFound) + assert.True(t, test.IsNormalPageCompleted(resp.Body.String()), "non-existing commit should render 404 page") +}
