[wsgi] avoid reading the entire request body in memory
Import POST form handling code from
https://raw.github.com/defnull/multipart/master/multipart.py to avoid
reading arbitrary amounts of data from the network in memory.
NOTES:
- In the twisted case we limit the max request content-length to 100MB (by
default), which seems kind of arbitrary, but avoids this issue
- werkzeug.formparser has suitable code as well, but I don't know if we want to
add it as a dependency
function showTooltip(x, y, contents) {
$('<div id="tooltip">' + contents + '</div>').css({
position: 'absolute',
display: 'none',
top: y + 5,
left: x + 5,
border: '1px solid #fdd',
padding: '2px',
'background-color': '#fee',
opacity: 0.80
}).appendTo("body").fadeIn(200);
}
var previousPoint = null;
function onPlotHover(event, pos, item) {
var $fig = $(event.target);
if (item) {
if (previousPoint != item.datapoint) {
previousPoint = item.datapoint;
$("#tooltip").remove();
var x = item.datapoint[0].toFixed(2),
y = item.datapoint[1].toFixed(2);
if ($fig.data('mode') == 'time') {
x = new Date(item.datapoint[0]);
var dateformat = $fig.data('dateformat');
if (dateformat) {
x = x.strftime(dateformat);
} else {
x = x.toLocaleDateString() + ' ' + x.toLocaleTimeString();
}
} else if (item.datapoint.length == 4) {
// NOTE: this has no chance to work with jquery flot >= 0.6 because
// jquery flot normalizes datapoints and only keeps 2 columns. Either
// use processRawData hook or use the 'dateformat' option.
x = new Date(item.datapoint[2]);
x = x.strftime(item.datapoint[3]);
