contrib/dimfeld/httptreemux.v5: fix route and name for 30X redirects #2664
Conversation
The httptreemux router has a redirect behaviour that is invoked when a request URL and matched route only differs in a trailing slash. The default behaviour is to respond with a 301 (moved permanently) to redirect the client to the exact path of the matched handler. We previously patched one of the two scenarios where this occurs in DataDog#2332. The changes in this commit addresses the other scenario for the 301 redirect, but also the 307 and 308 redirect options. Several tests were included to cover the various scenarios. We also standardize the resource name in the event that there is a trailing slash missmatch between request URL and matched handler. We always truncate the trailing slash in the resource name. Fixes DataDog#2663
Simplied the unnecessarily verbose function comments of isSupportedRedirectStatus and routerRedirectEnabled.
The new tests added to assert the redirect behaviour for the four redirect modes supported by the router had redundant test cases. These test cases were reduced down to three scenarios per redirect mode: 1. path not found 2. path with parameterized URL excluding a trailing slash 3. path with parameterized URL inclduing a trailing slash
When handling the supported redirect modes of the router we were incorrectly trimming trailing slashes from the route path matched by the router. The previous behaviour is restored where we return the exact path matched by the router.
