This program is a server for the WebDAV 'litmus' compliance test at

To run the test:
|
||
|
|
|
||
|
|
go run litmus_test_server.go
|
||
|
|
|

|
|
and separately, from the downloaded litmus-xxx directory:
|

|
|

make URL=http://localhost:9999/ check

// The propfind_invalid2 litmus test case expects an empty namespace prefix
|
||
|
|
// declaration to be an error. The FAQ in the webdav litmus test says:
|
||
|
|
//
|
||
|
|
// "What does the "propfind_invalid2" test check for?...
|
||
|
|
//
|
||
|
|
// If a request was sent with an XML body which included an empty namespace
|
||
|
|
// prefix declaration (xmlns:ns1=""), then the server must reject that with
|
||
|
|
// a "400 Bad Request" response, as it is invalid according to the XML
|
||
|
|
// Namespace specification."
|
||
|
|
//
|
||
|
|
// On the other hand, the Go standard library's encoding/xml package
|
||
|
|
// accepts an empty xmlns namespace, as per the discussion at
|
||
|
|
// https://github.com/golang/go/issues/8068
|
||
|
|
//
|
||
|
|
// Empty namespaces seem disallowed in the second (2006) edition of the XML
|
||
|
|
// standard, but allowed in a later edition. The grammar differs between
|
||
|
|
// http://www.w3.org/TR/2006/REC-xml-names-20060816/#ns-decl and
|
||
|
|
// http://www.w3.org/TR/REC-xml-names/#dt-prefix
|
||
|
|
//
|
||
|
|
// Thus, we assume that the propfind_invalid2 test is obsolete, and
|
||
|
|
// hard-code the 400 Bad Request response that the test expects.
