Aliaksandr Valialkin	9e0c37be2d	app/vmauth: properly proxy requests to backend paths ending with / ... Previously the traling / was incorrectly removed when proxying requests from http://vmauth/ While at it, add more tests for requestHandler()	2024-07-19 17:29:04 +02:00
Aliaksandr Valialkin	add2db12b2	app/vmauth: properly proxy HTTP requests without body ... The Request.Body for requests without body can be nil. This could break readTrackingBody.Read() logic, which could incorrectly return "cannot read data after closing the reader" error in this case. Fix this by initializing the readTrackingBody.r with zeroReader. While at it, properly set Host header if it is specified in 'headers' section. It must be set net/http.Request.Host instead of net/http.Request.Header.Set(), since the net/http.Client overwrites the Host header with the value from req.Host before sending the request. While at it, add tests for requestHandler(). Additional tests for various requestHandler() cases will be added in future commits.

Aliaksandr Valialkin	7ee5797493	app/vmauth: pool readTrackingBody structs in order to reduce pressure on Go GC ... - use pool for readTrackingBody structs in order to reduce pressure on Go GC - allow re-reading partially read request body - add missing tests for various cases of readTrackingBody usage This is a follow-up for ad6af95183 and 4d66e042e3.

Aliaksandr Valialkin	ad6af95183	Revert "app/vmauth: reader pool to reduce gc & mem alloc (#6533)" ... This reverts commit 4d66e042e3. Reasons for revert: - The commit makes unrelated invalid changes to docs/CHANGELOG.md - The changes at app/vmauth/main.go are too complex. It is better splitting them into two parts: - pooling readTrackingBody struct for reducing pressure on GC - avoiding to use readTrackingBody when -maxRequestBodySizeToRetry command-line flag is set to 0 Let's make this in the follow-up commits!
