Document the necessity to specifically configure X-HTTP-Method-Override=PATCH #90

Closed barkeldiho closed 1 year ago

barkeldiho commented 1 year ago

I tried to implement this tus-client for testing purposes of a Tus-compliant API in my Spring Boot application and had the following issue:

Since the TusUploader is using the HttpUrlConnection class to create a HTTP connection it suffers from a wont-fix bug in the OpenJDK (Ref.: https://stackoverflow.com/a/25163132). Consequently, the implementation sends a POST along with "X-HTTP-Method-Override" -> "PATCH" when it is running in JREs that do not support PATCH in that particular class.

Indeed the header "emulates" a PATCH request to be compliant with the TUS protocol specifications, but this needs to be specifically implemented on the server-side. E.g. in my case: @RequestMapping(method = RequestMethod.POST, headers = {"X-HTTP-Method-Override=PATCH"}, value = "/{id}")

This happened to me on Eclipse Termurin 17.0.5 JDK and is probably a wide-spread problem. My only recommendation would be to specifically mention this in your documentation as this will reduce implementation overhead. And most importantly: It means that this client is not 100% Tus compliant.

Thank you for bringing this up. I thought that this affected only JDKs which do not support sending PATCH requests, but that there are JDKs which are capable of doing so. Therefore, X-HTTP-Method-Override support should not always be necessary.

We hope to alleviate this issue all together by moving to a more modern HTTP client in the near future anyways.

Dear Acconut,

thanks for your kind reply. I agree that moving to another HTTP client will solve this issue. Keep up the good work!

Are there any plans to migrate to the new java HttpClient that was introduced with jdk 11? This is a mandatory requirement for making the tus-java-client ready for JDK 17.

@mdzhigarov The new HttpClient looks interesting. I will see if it is suitable for tus-java-client. We plan to upgrade to a more modern HTTP stack for the next bigger release, so this is on our radar: https://github.com/tus/tus-java-client/issues/78
