RBokeh not working on Firefox on macOS from conda.

[mingwandroid]

This issue began over at https://github.com/ContinuumIO/anaconda-issues/issues/1391, but has now morphed into something that seems to be rbokeh specific. Conda defaults has the latest packages for nearly all of this stack at present. A simple example of RBokeh works fine in Chrome and also Safari but not in Firefox.

To create the environment:

pushd /tmp
curl -SLO https://repo.continuum.io/miniconda/Miniconda3-latest-MacOSX-x86_64.sh
bash ./Miniconda3-latest-MacOSX-x86_64.sh -b -p /tmp/jupyter
source /tmp/jupyter/bin/activate
conda create -n dspyr r-essentials=1.5.2 -y
source activate dspyr
jupyter notebook

Test-case:

options(jupyter.log_level=10)
library(dplyr)
library(rbokeh)
z <- lm(dist ~ speed, data = cars)
p <- figure(width = 600, height = 600) %>%
  ly_points(cars, hover = cars) %>%
  ly_lines(lowess(cars), legend = "lowess") %>%
  ly_abline(z, type = 2, legend = "lm")
p

Warning from Chrome:

Error from Firefox:

TypeError: body is null[Learn More]  main.min.js:20309:17
    OutputArea.prototype.create_output_subarea/< http://localhost:8888/static/notebook/js/main.min.js:20309:17
    x.event.dispatch http://localhost:8888/static/notebook/js/main.min.js:88:9954
    x.event.add/y.handle

In main.min.js I see:

    OutputArea.prototype.create_output_subarea = function(md, classes, mime) {
        var subarea = $('<div/>').addClass('output_subarea').addClass(classes);

            // Create an iframe to isolate the subarea from the rest of the
            // document
            var iframe = $('<iframe/>').addClass('box-flex1');
            iframe.css({'height':1, 'width':'100%', 'display':'block'});
            iframe.attr('frameborder', 0);
            iframe.attr('scrolling', 'auto');

            // Once the iframe is loaded, the subarea is dynamically inserted
            iframe.on('load', function() {
                // Workaround needed by Firefox, to properly render svg inside
                // iframes, see http://stackoverflow.com/questions/10177190/
                // svg-dynamically-added-to-iframe-does-not-render-correctly
                this.contentDocument.open();

                // Insert the subarea into the iframe
                // We must directly write the html. When using Jquery's append
                // method, javascript is evaluated in the parent document and
                // not in the iframe document.  At this point, subarea doesn't
                // contain any user content.
                this.contentDocument.write(subarea.html());

                this.contentDocument.close();

                var body = this.contentDocument.body;
                // Adjust the iframe height automatically
                iframe.height(body.scrollHeight + 'px');
            });

            // Elements should be appended to the inner subarea and not to the
            // iframe
            iframe.append = function(that) {
                subarea.append(that);
            };

            return iframe;
        } else {
            return subarea;
        }
    };

Here:

                var body = this.contentDocument.body;
                // Adjust the iframe height automatically
                iframe.height(body.scrollHeight + 'px');

body (and this.contentDocument.body) is null.

A screen-grab of the Firefox debugger:

.. hopefully this is useful?

I believe the FF thing is an issue that might effect all htmlwidgets in notebooks, not just rbokeh. For example, I tried another htmlwidget, d3heatmap:

library(d3heatmap)
d3heatmap(mtcars, scale = "column", colors = "Spectral", width = 500, height = 500)

And it doesn't work in a notebook in FF but it works in Chrome and Safari. Can you try this example and see if there are commonalities in the errors?

@hafen are you talking about jupyter notebooks? can you provide a reproducible example.

I tried this:

devtools::install_github('jjallaire/sigma')
library(sigma)
sigma(system.file("examples/ediaspora.gexf.xml", package = "sigma"))

and got the same thing, no joy from Firefox (exact same exception), worked fine in Chrome and Safari.

Is there any progress on this? I'd love to be able to recommend Firefox here but cannot.

hi, i didn’t find a solution for this yet, but if you get some recursion error killing your IRkernel, please upgrade IRkernel 0.8.7→0.8.8
