However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform. A single 4MB write could -// cause the system to run out of memory. +// The above copyright notice and this permission notice shall be included +// in all copies or substantial portions of the Software. // -// However, even in such a pathological case, only a single written chunk -// would be consumed, and then the rest would wait (un-transformed) until -// the results of the previous transformed chunk were consumed. +// THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS +// OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF +// MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. +'use strict'; -module.exports = parseUrlString; +module.exports = Transform; -},{"url":139}],104:[function(require,module,exports){ -"use strict"; +var Duplex = require('./_stream_duplex'); -var findRelation = require("./findRelation"); -var objUtils = require("../util/object"); -var pathUtils = require("../util/path"); +/**/ +var util = require('core-util-is'); +util.inherits = require('inherits'); +/**/ +util.inherits(Transform, Duplex); +function TransformState(stream) { + this.afterTransform = function (er, data) { + return afterTransform(stream, er, data); + }; -function absolutize(urlObj, siteUrlObj, options) -{ - findRelation.upToPath(urlObj, siteUrlObj, options); - - // Fill in relative URLs - if (urlObj.extra.relation.minimumScheme) urlObj.scheme = siteUrlObj.scheme; - if (urlObj.extra.relation.minimumAuth) urlObj.auth = siteUrlObj.auth; - if (urlObj.extra.relation.minimumHost) urlObj.host = objUtils.clone(siteUrlObj.host); - if (urlObj.extra.relation.minimumPort) copyPort(urlObj, siteUrlObj); - if (urlObj.extra.relation.minimumScheme) copyPath(urlObj, siteUrlObj); - - // Check remaining relativeness now that path has been copied and/or resolved - findRelation.pathOn(urlObj, siteUrlObj, options); - - // Fill in relative URLs - if (urlObj.extra.relation.minimumResource) copyResource(urlObj, siteUrlObj); - if (urlObj.extra.relation.minimumQuery) urlObj.query = objUtils.clone(siteUrlObj.query); - if (urlObj.extra.relation.minimumHash) urlObj.hash = siteUrlObj.hash; + this.needTransform = false; + this.transforming = false; + this.writecb = null; + this.writechunk = null; + this.writeencoding = null; } +function afterTransform(stream, er, data) { + var ts = stream._transformState; + ts.transforming = false; + var cb = ts.writecb; -/* - Get an absolute path that's relative to site url. -*/ -function copyPath(urlObj, siteUrlObj) -{ - if (urlObj.extra.relation.maximumHost || !urlObj.extra.hrefInfo.minimumResourceOnly) - { - var pathArray = urlObj.path.absolute.array; - var pathString = "/"; - - // If not erroneous URL - if (pathArray) - { - // If is relative path - if (urlObj.extra.hrefInfo.minimumPathOnly && urlObj.path.absolute.string.indexOf("/")!==0) - { - // Append path to site path - pathArray = siteUrlObj.path.absolute.array.concat(pathArray); - } - - pathArray = pathUtils.resolveDotSegments(pathArray); - pathString += pathUtils.join(pathArray); - } - else - { - pathArray = []; - } - - urlObj.path.absolute.array = pathArray; - urlObj.path.absolute.string = pathString; - } - else - { - // Resource-, query- or hash-only or empty - urlObj.path = objUtils.clone(siteUrlObj.path); - } -} - - + if (!cb) return stream.emit('error', new Error('no writecb in Transform class')); -function copyPort(urlObj, siteUrlObj) -{ - urlObj.port = siteUrlObj.port; - - urlObj.extra.portIsDefault = siteUrlObj.extra.portIsDefault; -} + ts.writechunk = null; + ts.writecb = null; + if (data !== null && data !== undefined) stream.push(data); + cb(er); -function copyResource(urlObj, siteUrlObj) -{ - urlObj.resource = siteUrlObj.resource; - - urlObj.extra.resourceIsIndex = siteUrlObj.extra.resourceIsIndex; + var rs = stream._readableState; + rs.reading = false; + if (rs.needReadable || rs.length < rs.highWaterMark) { + stream._read(rs.highWaterMark); + } } +function Transform(options) { + if (!(this instanceof Transform)) return new Transform(options); + Duplex.call(this, options); -module.exports = absolutize; + this._transformState = new TransformState(this); -},{"../util/object":108,"../util/path":109,"./findRelation":105}],105:[function(require,module,exports){ -"use strict"; + var stream = this; -function findRelation_upToPath(urlObj, siteUrlObj, options) -{ - // Path- or root-relative URL - var pathOnly = urlObj.extra.hrefInfo.minimumPathOnly; - - // Matching scheme, scheme-relative or path-only - var minimumScheme = (urlObj.scheme===siteUrlObj.scheme || !urlObj.scheme); - - // Matching auth, ignoring auth or path-only - var minimumAuth = minimumScheme && (urlObj.auth===siteUrlObj.auth || options.removeAuth || pathOnly); - - // Matching host or path-only - var www = options.ignore_www ?
