backport: github: fix erratic 404s by keeping URL stable (#56478)#56495
Merged
Conversation
See [this comment](sourcegraph/customer#2329 (comment)) and the issue it's in for full context. Short version: 1. GitHub v3 and v4 clients execute this bit of code multiple times when retrying a request after it ran into rate limits: https://github.com/sourcegraph/sourcegraph/blob/16458d7e5c07ac69d00d32841a1a7dcd55a50ddb/internal/extsvc/github/common.go#L1589-L1590 2. When executed multiple times with the same `url.URL`, `req.URL.Path` ends up with invalid paths like `/api/v3/api/v3` That lead to 404 errors showing up _sometimes_: when the client runs into rate limit and retries. And _sometimes_ these 404s were even ignored and lead to a "successful" end of the syncing process. This changes the behaviour of the clients to keep a copy of the original `req.URL` around so that modifications made by `doRequest` don't have unintended side-effects. (cherry picked from commit 8e21962)
