From 4562d40fcead66e54525f710875377ebf7c4766e Mon Sep 17 00:00:00 2001 From: Peter Gardfjäll Date: Mon, 29 Aug 2022 11:45:20 +0200 Subject: fix hard-coded timeout and error panic in API archive download endpoint (#20925) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * fix hard-coded timeout and error panic in API archive download endpoint This commit updates the `GET /api/v1/repos/{owner}/{repo}/archive/{archive}` endpoint which prior to this PR had a couple of issues. 1. The endpoint had a hard-coded 20s timeout for the archiver to complete after which a 500 (Internal Server Error) was returned to client. For a scripted API client there was no clear way of telling that the operation timed out and that it should retry. 2. Whenever the timeout _did occur_, the code used to panic. This was caused by the API endpoint "delegating" to the same call path as the web, which uses a slightly different way of reporting errors (HTML rather than JSON for example). More specifically, `api/v1/repo/file.go#GetArchive` just called through to `web/repo/repo.go#Download`, which expects the `Context` to have a `Render` field set, but which is `nil` for API calls. Hence, a `nil` pointer error. The code addresses (1) by dropping the hard-coded timeout. Instead, any timeout/cancelation on the incoming `Context` is used. The code addresses (2) by updating the API endpoint to use a separate call path for the API-triggered archive download. This avoids producing HTML-errors on errors (it now produces JSON errors).
