Hoernschen a6e9510c07 FIX blank internal pages (#164) (#292) ... Hello 👋 since it affected my deployment of the pages server I started to look into the problem of the blank pages and think I found a solution for it: 1. There is no check if the file response is empty, neither in cache retrieval nor in writing of a cache. Also the provided method for checking for empty responses had a bug. 2. I identified the redirect response to be the issue here. There is a cache write with the full cache key (e. g. rawContent/user/repo|branch|route/index.html) happening in the handling of the redirect response. But the written body here is empty. In the triggered request from the redirect response the server then finds a cache item to the key and serves the empty body. A quick fix is the check for empty file responses mentioned in 1. 3. The decision to redirect the user comes quite far down in the upstream function. Before that happens a lot of stuff that may not be important since after the redirect response comes a new request anyway. Also, I suspect that this causes the caching problem because there is a request to the forge server and its error handling with some recursions happening before. I propose to move two of the redirects before "Preparing" 4. The recursion in the upstream function makes it difficult to understand what is actually happening. I added some more logging to have an easier time with that. 5. I changed the default behaviour to append a trailing slash to the path to true. In my tested scenarios it happened anyway. This way there is no recursion happening before the redirect. I am not developing in go frequently and rarely contribute to open source -> so feedback of all kind is appreciated closes #164 Reviewed-on: https://codeberg.org/Codeberg/pages-server/pulls/292 Reviewed-by: 6543 <6543@obermui.de> Reviewed-by: crapStone <codeberg@crapstone.dev> Co-authored-by: Hoernschen <julian.hoernschemeyer@mailbox.org> Co-committed-by: Hoernschen <julian.hoernschemeyer@mailbox.org>		2024-02-26 22:21:42 +00:00
