Many variables were copied from the dynamic environment to the request buffer, which allowed them to influence the handling of requests and responses. But some were not, notably some of the mime-related variables, and the user-agent and privacy variables. This made them unreliable when dynamically bound around a call to `url-retrieve'; they would have the desired effect when reusing an existing connection, but not when url-http opened a new connection. In the case of reused connections, the request construction happens in the dynamic scope of `url-http', but in the case where a fresh connection is needed, request construction happens outside that dynamic scope. This commit adds the remaining variables used in request construction to the set of buffer local variables mirroring the dynamic values from url-http, and adds a comment describing the mechanism used and how avoid the pitfall of inconsistent handling of dynamic bindings. * lisp/url/url-http.el (url-http-extensions-header): New internal-ish variable. (url-http-create-request): Use the new variable instead of the global one. (url-http-idle-sentinel): Debug-log when the connection closes. (url-http): Set up more buffer-local variants of dynamic variables in the buffer used for the request, and add comment describing why this copying is needed. (Bug#61916) |
