From 4ae3f762177a2cdb449b949501420e88462f8f95 Mon Sep 17 00:00:00 2001 From: Jason Song Date: Mon, 31 Oct 2022 23:10:33 +0800 Subject: [PATCH] Deal with markdown template without metadata (#21639) Fixed #21636. Related to #20987. A markdown template without metadata should not be treated as an invalid template. And this PR fixed another bug that non-template files(neither .md nor .yaml) are treated as yaml files. image --- modules/issue/template/unmarshal.go | 30 +++++++++++++++++++++-------- modules/structs/issue.go | 4 ++-- 2 files changed, 24 insertions(+), 10 deletions(-) diff --git a/modules/issue/template/unmarshal.go b/modules/issue/template/unmarshal.go index e695d1e1cc..24587b0fed 100644 --- a/modules/issue/template/unmarshal.go +++ b/modules/issue/template/unmarshal.go @@ -14,6 +14,7 @@ import ( "code.gitea.io/gitea/modules/markup/markdown" "code.gitea.io/gitea/modules/setting" api "code.gitea.io/gitea/modules/structs" + "code.gitea.io/gitea/modules/util" "gopkg.in/yaml.v2" ) @@ -95,14 +96,27 @@ func unmarshal(filename string, content []byte) (*api.IssueTemplate, error) { }{} if typ := it.Type(); typ == api.IssueTemplateTypeMarkdown { - templateBody, err := markdown.ExtractMetadata(string(content), it) - if err != nil { - return nil, err - } - it.Content = templateBody - if it.About == "" { - if _, err := markdown.ExtractMetadata(string(content), compatibleTemplate); err == nil && compatibleTemplate.About != "" { - it.About = compatibleTemplate.About + if templateBody, err := markdown.ExtractMetadata(string(content), it); err != nil { + // The only thing we know here is that we can't extract metadata from the content, + // it's hard to tell if metadata doesn't exist or metadata isn't valid. + // There's an example template: + // + // --- + // # Title + // --- + // Content + // + // It could be a valid markdown with two horizontal lines, or an invalid markdown with wrong metadata. + + it.Content = string(content) + it.Name = filepath.Base(it.FileName) + it.About, _ = util.SplitStringAtByteN(it.Content, 80) + } else { + it.Content = templateBody + if it.About == "" { + if _, err := markdown.ExtractMetadata(string(content), compatibleTemplate); err == nil && compatibleTemplate.About != "" { + it.About = compatibleTemplate.About + } } } } else if typ == api.IssueTemplateTypeYaml { diff --git a/modules/structs/issue.go b/modules/structs/issue.go index 27ec81f728..70f5e1ba8e 100644 --- a/modules/structs/issue.go +++ b/modules/structs/issue.go @@ -170,7 +170,7 @@ func (it IssueTemplate) Type() IssueTemplateType { if ext := filepath.Ext(it.FileName); ext == ".md" { return IssueTemplateTypeMarkdown } else if ext == ".yaml" || ext == ".yml" { - return "yaml" + return IssueTemplateTypeYaml } - return IssueTemplateTypeYaml + return "" }
