[Bioc-devel] BrowserViz build test times out, checks for web browser availability, apparently needs update

[Vincent Carey]

Sorry for delay in responding Paul.  I had a look at BrowserViz and ran into

> PORT_RANGE <- 12111:12120
> if(BrowserViz::webBrowserAvailableForTesting()){
+    bvApp <- BrowserViz(browserFile=browserVizBrowserFile, quiet=TRUE)
+    data <- list(lowercase=letters, uppercase=LETTERS)
+    json.returned <- roundTripTest(bvApp, data)
+    data.returned <- fromJSON(json.returned)
+    message(sprintf("    %5d bytes exchanged", nchar(json.returned)))
+    stopifnot(data == data.returned)
+    html <- sprintf("<h3>round trip of json-encoded data, %d chars</h3>",
+                    nchar(json.returned))
+    displayHTMLInDiv(bvApp, html, "bvDemoDiv")
+    }
attempting to open websocket connection on port 10000
BrowserViz websocket ready after   1.30 seconds
      237 bytes exchanged
Error in data == data.returned :
  comparison of these types is not implemented

Maybe we can discuss this on issues in BrowserViz github ... where is
that?  Then
we can bring back the solution to bioc-devel.
