From dd8bc1d61d897f967aaa621490d1943be568a368 Mon Sep 17 00:00:00 2001 From: wxiaoguang Date: Wed, 14 Feb 2024 09:32:31 +0800 Subject: [PATCH] Refactor issue template parsing and fix API endpoint (#29069) (#29140) Backport #29069 The old code `GetTemplatesFromDefaultBranch(...) ([]*api.IssueTemplate, map[string]error)` doesn't really follow Golang's habits, then the second returned value might be misused. For example, the API function `GetIssueTemplates` incorrectly checked the second returned value and always responds 500 error. This PR refactors GetTemplatesFromDefaultBranch to ParseTemplatesFromDefaultBranch and clarifies its behavior, and fixes the API endpoint bug, and adds some tests. And by the way, add proper prefix `X-` for the header generated in `checkDeprecatedAuthMethods`, because non-standard HTTP headers should have `X-` prefix, and it is also consistent with the new code in `GetIssueTemplates` --- routers/api/v1/api.go | 2 +- routers/api/v1/repo/repo.go | 10 ++-- routers/web/repo/issue.go | 20 +++---- routers/web/repo/milestone.go | 4 +- services/issue/template.go | 30 +++++----- tests/integration/api_issue_templates_test.go | 55 +++++++++++++++++++ 6 files changed, 88 insertions(+), 33 deletions(-) create mode 100644 tests/integration/api_issue_templates_test.go diff --git a/routers/api/v1/api.go b/routers/api/v1/api.go index 8dba0a790..c38a7ce8c 100644 --- a/routers/api/v1/api.go +++ b/routers/api/v1/api.go @@ -810,7 +810,7 @@ func individualPermsChecker(ctx *context.APIContext) { // check for and warn against deprecated authentication options func checkDeprecatedAuthMethods(ctx *context.APIContext) { if ctx.FormString("token") != "" || ctx.FormString("access_token") != "" { - ctx.Resp.Header().Set("Warning", "token and access_token API authentication is deprecated and will be removed in gitea 1.23.
