* Only compare hostnames in ws.origins

Also using a helper function for ToLower consolidates all preparation steps in one function for more maintainable consistency.

Spaces => tabs

Remove a semicolon

Add space at start of comment

Remove parens around conditional

Handle case wehre parsed hostname is empty

When passing a single word like "localhost" the parsed hostname is an empty string. Handle this and the error-parsing case together as default, and the nonempty hostname case in the conditional.

Refactor with new originIsAllowed functions

Adds originIsAllowed() & ruleAllowsOrigin(); removes prepOriginForComparison

Remove blank line

Added tests for simple allowed-orign rule

which does not specify a protocol or port, just a hostname

Fix copy-paste: `:=` => `=`

Remove parens around conditional

Remove autoadded whitespace on blank lines

Compare scheme, hostname, and port with rule

if the rule specifies those portions.

Remove one autoadded trailing whitespace

Better handle case where only origin host is given

e.g. "localhost"

Remove parens around conditional

Refactor: attemptWebsocketConnectionFromOrigin DRY

Include return type on helper function

Provide srv obj in helper fn

Provide srv to helper fn

Remove stray underscore

Remove blank line

Refactor: drop err var for more concise test lines

Add several tests for new WebSocket origin checks

Remove autoadded whitespace on blank lines

Restore TestWebsocketOrigins originally-named test

and rename the others to be helpers rather than full tests

Remove autoadded whitespace on blank line

Temporarily comment out new test sets

Uncomment test around origin rule with scheme

Remove tests without scheme on browser origin

per https://github.com/ethereum/go-ethereum/pull/21481/files#r479371498



Uncomment tests with port; remove some blank lines

Handle when browser does not specify scheme/port

Uncomment test for including scheme & port in rule

The z == 0 check is hit whenever we Add two points with the same x1/x2
coordinate. crypto/elliptic uses the same check in their affineFromJacobian
function. This change does not affect block processing or tx signature verification
in any way, because it does not use the Add or Double methods.
