From: Brian Warner Date: Fri, 25 Apr 2014 23:16:05 +0000 (-0700) Subject: Include unminified versions of d3+jquery. Addresses #2208. X-Git-Tag: allmydata-tahoe-1.10.1a1~188 X-Git-Url: https://git.rkrishnan.org/vdrive/%22news.html/simplejson/frontends?a=commitdiff_plain;h=b6c0297deea77cce2aa22458f0645635cb1aa50d;p=tahoe-lafs%2Ftahoe-lafs.git Include unminified versions of d3+jquery. Addresses #2208. This should hopefully satisfy the Debian requirement to include original sources. The old minified files for d3 and jquery were 63k and 91k respectively, while the new unminified files are 133k and 293k. --- diff --git a/src/allmydata/web/download-status-timeline.xhtml b/src/allmydata/web/download-status-timeline.xhtml index c7e923e8..03fb629f 100644 --- a/src/allmydata/web/download-status-timeline.xhtml +++ b/src/allmydata/web/download-status-timeline.xhtml @@ -4,9 +4,9 @@ - - - + + + diff --git a/src/allmydata/web/static/d3-2.4.6.js b/src/allmydata/web/static/d3-2.4.6.js new file mode 100644 index 00000000..d24c2e4c --- /dev/null +++ b/src/allmydata/web/static/d3-2.4.6.js @@ -0,0 +1,4150 @@ +(function(){if (!Date.now) Date.now = function() { + return +new Date; +}; +try { + document.createElement("div").style.setProperty("opacity", 0, ""); +} catch (error) { + var d3_style_prototype = CSSStyleDeclaration.prototype, + d3_style_setProperty = d3_style_prototype.setProperty; + d3_style_prototype.setProperty = function(name, value, priority) { + d3_style_setProperty.call(this, name, value + "", priority); + }; +} +d3 = {version: "2.4.6"}; // semver +var d3_array = d3_arraySlice; // conversion for NodeLists + +function d3_arrayCopy(pseudoarray) { + var i = -1, n = pseudoarray.length, array = []; + while (++i < n) array.push(pseudoarray[i]); + return array; +} + +function d3_arraySlice(pseudoarray) { + return Array.prototype.slice.call(pseudoarray); +} + +try { + d3_array(document.documentElement.childNodes)[0].nodeType; +} catch(e) { + d3_array = d3_arrayCopy; +} + +var d3_arraySubclass = [].__proto__? + +// Until ECMAScript supports array subclassing, prototype injection works well. +function(array, prototype) { + array.__proto__ = prototype; +}: + +// And if your browser doesn't support __proto__, we'll use direct extension. +function(array, prototype) { + for (var property in prototype) array[property] = prototype[property]; +}; +function d3_this() { + return this; +} +d3.functor = function(v) { + return typeof v === "function" ? v : function() { return v; }; +}; +// A getter-setter method that preserves the appropriate `this` context. +d3.rebind = function(object, method) { + return function() { + var x = method.apply(object, arguments); + return arguments.length ? object : x; + }; +}; +d3.ascending = function(a, b) { + return a < b ? -1 : a > b ? 1 : a >= b ? 0 : NaN; +}; +d3.descending = function(a, b) { + return b < a ? -1 : b > a ? 1 : b >= a ? 0 : NaN; +}; +d3.mean = function(array, f) { + var n = array.length, + a, + m = 0, + i = -1, + j = 0; + if (arguments.length === 1) { + while (++i < n) if (d3_number(a = array[i])) m += (a - m) / ++j; + } else { + while (++i < n) if (d3_number(a = f.call(array, array[i], i))) m += (a - m) / ++j; + } + return j ? m : undefined; +}; +d3.median = function(array, f) { + if (arguments.length > 1) array = array.map(f); + array = array.filter(d3_number); + return array.length ? d3.quantile(array.sort(d3.ascending), .5) : undefined; +}; +d3.min = function(array, f) { + var i = -1, + n = array.length, + a, + b; + if (arguments.length === 1) { + while (++i < n && ((a = array[i]) == null || a != a)) a = undefined; + while (++i < n) if ((b = array[i]) != null && a > b) a = b; + } else { + while (++i < n && ((a = f.call(array, array[i], i)) == null || a != a)) a = undefined; + while (++i < n) if ((b = f.call(array, array[i], i)) != null && a > b) a = b; + } + return a; +}; +d3.max = function(array, f) { + var i = -1, + n = array.length, + a, + b; + if (arguments.length === 1) { + while (++i < n && ((a = array[i]) == null || a != a)) a = undefined; + while (++i < n) if ((b = array[i]) != null && b > a) a = b; + } else { + while (++i < n && ((a = f.call(array, array[i], i)) == null || a != a)) a = undefined; + while (++i < n) if ((b = f.call(array, array[i], i)) != null && b > a) a = b; + } + return a; +}; +function d3_number(x) { + return x != null && !isNaN(x); +} +d3.sum = function(array, f) { + var s = 0, + n = array.length, + a, + i = -1; + + if (arguments.length === 1) { + while (++i < n) if (!isNaN(a = +array[i])) s += a; + } else { + while (++i < n) if (!isNaN(a = +f.call(array, array[i], i))) s += a; + } + + return s; +}; +// R-7 per +d3.quantile = function(values, p) { + var H = (values.length - 1) * p + 1, + h = Math.floor(H), + v = values[h - 1], + e = H - h; + return e ? v + e * (values[h] - v) : v; +}; +d3.zip = function() { + if (!(n = arguments.length)) return []; + for (var i = -1, m = d3.min(arguments, d3_zipLength), zips = new Array(m); ++i < m;) { + for (var j = -1, n, zip = zips[i] = new Array(n); ++j < n;) { + zip[j] = arguments[j][i]; + } + } + return zips; +}; + +function d3_zipLength(d) { + return d.length; +} +// Locate the insertion point for x in a to maintain sorted order.
