You must have WRITE permissions on a bucket to add an object\n * to it.
\n *\n *\n * Amazon S3 never adds partial objects; if you receive a success response, Amazon S3 added the\n * entire object to the bucket.
\n *\n * Amazon S3 is a distributed system. If it receives multiple write requests for the same object\n * simultaneously, it overwrites all but the last object written. Amazon S3 does not provide object\n * locking; if you need this, make sure to build it into your application layer or use\n * versioning instead.
\n *\n * To ensure that data is not corrupted traversing the network, use the\n * Content-MD5 header. When you use this header, Amazon S3 checks the object\n * against the provided MD5 value and, if they do not match, returns an error. Additionally,\n * you can calculate the MD5 while putting an object to Amazon S3 and compare the returned ETag to\n * the calculated MD5 value.
\n * \n * The Content-MD5 header is required for any request to upload an object\n * with a retention period configured using Amazon S3 Object Lock. For more information about\n * Amazon S3 Object Lock, see Amazon S3 Object Lock Overview\n * in the Amazon Simple Storage Service Developer Guide.
\n * \n *\n *\n * \n * Server-side Encryption\n *
\n * You can optionally request server-side encryption. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data\n * when you access it. You have the option to provide your own encryption key or use AWS\n * managed encryption keys (SSE-S3 or SSE-KMS). For more information, see Using Server-Side\n * Encryption.
\n * If you request server-side encryption using AWS Key Management Service (SSE-KMS), you can enable an S3 Bucket Key at the object-level. For more information, see Amazon S3 Bucket Keys in the Amazon Simple Storage Service Developer Guide.
\n * \n * Access Control List (ACL)-Specific Request\n * Headers\n *
\n * You can use headers to grant ACL- based permissions. By default, all objects are\n * private. Only the owner has full access control. When adding a new object, you can grant\n * permissions to individual AWS accounts or to predefined groups defined by Amazon S3. These\n * permissions are then added to the ACL on the object. For more information, see Access Control List\n * (ACL) Overview and Managing ACLs Using the REST\n * API.
\n *\n * \n * Storage Class Options\n *
\n * By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The\n * STANDARD storage class provides high durability and high availability. Depending on\n * performance needs, you can specify a different Storage Class. Amazon S3 on Outposts only uses\n * the OUTPOSTS Storage Class. For more information, see Storage Classes in the Amazon S3\n * Service Developer Guide.
\n *\n *\n * \n * Versioning\n *
\n * If you enable versioning for a bucket, Amazon S3 automatically generates a unique version ID\n * for the object being stored. Amazon S3 returns this ID in the response. When you enable\n * versioning for a bucket, if Amazon S3 receives multiple write requests for the same object\n * simultaneously, it stores all of the objects.
\n * For more information about versioning, see Adding Objects to\n * Versioning Enabled Buckets. For information about returning the versioning state\n * of a bucket, see GetBucketVersioning.

You also include this\n * upload ID in the final request to either complete or abort the multipart upload\n * request.
\n *\n * For more information about multipart uploads, see Multipart Upload Overview.
\n *\n * If you have configured a lifecycle rule to abort incomplete multipart uploads, the\n * upload must complete within the number of days specified in the bucket lifecycle\n * configuration. Otherwise, the incomplete multipart upload becomes eligible for an abort\n * operation and Amazon S3 aborts the multipart upload. For more information, see Aborting\n * Incomplete Multipart Uploads Using a Bucket Lifecycle Policy.
\n *\n * For information about the permissions required to use the multipart upload API, see\n * Multipart Upload API and\n * Permissions.
\n *\n * For request signing, multipart upload is just a series of regular requests. You initiate\n * a multipart upload, send one or more requests to upload parts, and then complete the\n * multipart upload process. You sign each request individually. There is nothing special\n * about signing multipart upload requests. For more information about signing, see Authenticating\n * Requests (AWS Signature Version 4).
\n *\n * \n * After you initiate a multipart upload and upload one or more parts, to stop being\n * charged for storing the uploaded parts, you must either complete or abort the multipart\n * upload. Amazon S3 frees up the space used to store the parts and stop charging you for\n * storing them only after you either complete or abort a multipart upload.
\n * \n *\n * You can optionally request server-side encryption. For server-side encryption, Amazon S3\n * encrypts your data as it writes it to disks in its data centers and decrypts it when you\n * access it. You can provide your own encryption key, or use AWS Key Management Service (AWS\n * KMS) customer master keys (CMKs) or Amazon S3-managed encryption keys. If you choose to provide\n * your own encryption key, the request headers you provide in UploadPart and UploadPartCopy requests must match the headers you used in the request to\n * initiate the upload by using CreateMultipartUpload.
\n * To perform a multipart upload with encryption using an AWS KMS CMK, the requester must\n * have permission to the kms:Encrypt, kms:Decrypt,\n * kms:ReEncrypt*, kms:GenerateDataKey*, and\n * kms:DescribeKey actions on the key. These permissions are required because\n * Amazon S3 must decrypt and read data from the encrypted file parts before it completes the\n * multipart upload.
\n *\n * If your AWS Identity and Access Management (IAM) user or role is in the same AWS account\n * as the AWS KMS CMK, then you must have these permissions on the key policy. If your IAM\n * user or role belongs to a different account than the key, then you must have the\n * permissions on both the key policy and your IAM user or role.
\n *\n *\n * For more information, see Protecting\n * Data Using Server-Side Encryption.
\n *\n * \n * - Access Permissions
\n * - \n *
When copying an object, you can optionally specify the accounts or groups that\n * should be granted specific permissions on the new object. There are two ways to\n * grant the permissions using the request headers:
\n * \n * - \n *
Specify a canned ACL with the x-amz-acl request header. For\n * more information, see Canned ACL.
\n * \n * - \n *
Specify access permissions explicitly with the\n * x-amz-grant-read, x-amz-grant-read-acp,\n * x-amz-grant-write-acp, and\n * x-amz-grant-full-control headers. These parameters map to\n * the set of permissions that Amazon S3 supports in an ACL. For more information,\n * see Access Control List (ACL)\n * Overview.
\n * \n *
\n * You can use either a canned ACL or specify access permissions explicitly. You\n * cannot do both.
\n * \n * - Server-Side- Encryption-Specific Request Headers
\n * - \n *
You can optionally tell Amazon S3 to encrypt data at rest using server-side\n * encryption. Server-side encryption is for data encryption at rest. Amazon S3 encrypts\n * your data as it writes it to disks in its data centers and decrypts it when you\n * access it. The option you use depends on whether you want to use AWS managed\n * encryption keys or provide your own encryption key.
\n * \n * - \n *
Use encryption keys managed by Amazon S3 or customer master keys (CMKs) stored\n * in AWS Key Management Service (AWS KMS) – If you want AWS to manage the keys\n * used to encrypt data, specify the following headers in the request.
\n * \n * - \n *
x-amz-server-side-encryption
\n * \n * - \n *
x-amz-server-side-encryption-aws-kms-key-id
\n * \n * - \n *
x-amz-server-side-encryption-context
\n * \n *
\n * \n * If you specify x-amz-server-side-encryption:aws:kms, but\n * don't provide x-amz-server-side-encryption-aws-kms-key-id,\n * Amazon S3 uses the AWS managed CMK in AWS KMS to protect the data.
\n * \n * \n * All GET and PUT requests for an object protected by AWS KMS fail if\n * you don't make them with SSL or by using SigV4.
\n * \n * For more information about server-side encryption with CMKs stored in AWS\n * KMS (SSE-KMS), see Protecting Data Using Server-Side Encryption with CMKs stored in AWS\n * KMS.
\n * \n * - \n *
Use customer-provided encryption keys – If you want to manage your own\n * encryption keys, provide all the following headers in the request.
\n * \n * - \n *
x-amz-server-side-encryption-customer-algorithm
\n * \n * - \n *
x-amz-server-side-encryption-customer-key
\n * \n * - \n *
x-amz-server-side-encryption-customer-key-MD5
\n * \n *
\n * For more information about server-side encryption with CMKs stored in AWS\n * KMS (SSE-KMS), see Protecting Data Using Server-Side Encryption with CMKs stored in AWS\n * KMS.
\n * \n *
\n * \n * - Access-Control-List (ACL)-Specific Request Headers
\n * - \n *
You also can use the following access control–related headers with this\n * operation. By default, all objects are private. Only the owner has full access\n * control. When adding a new object, you can grant permissions to individual AWS\n * accounts or to predefined groups defined by Amazon S3. These permissions are then added\n * to the access control list (ACL) on the object. For more information, see Using ACLs. With this\n * operation, you can grant access permissions using one of the following two\n * methods:
\n * \n * - \n *
Specify a canned ACL (x-amz-acl) — Amazon S3 supports a set of\n * predefined ACLs, known as canned ACLs. Each canned ACL\n * has a predefined set of grantees and permissions. For more information, see\n * Canned\n * ACL.
\n * \n * - \n *
Specify access permissions explicitly — To explicitly grant access\n * permissions to specific AWS accounts or groups, use the following headers.\n * Each header maps to specific permissions that Amazon S3 supports in an ACL. For\n * more information, see Access\n * Control List (ACL) Overview. In the header, you specify a list of\n * grantees who get the specific permission. To grant permissions explicitly,\n * use:
\n * \n * - \n *
x-amz-grant-read
\n * \n * - \n *
x-amz-grant-write
\n * \n * - \n *
x-amz-grant-read-acp
\n * \n * - \n *
x-amz-grant-write-acp
\n * \n * - \n *
x-amz-grant-full-control
\n * \n *
\n * You specify each grantee as a type=value pair, where the type is one of\n * the following:
\n * \n * - \n *
\n * id – if the value specified is the canonical user ID\n * of an AWS account
\n * \n * - \n *
\n * uri – if you are granting permissions to a predefined\n * group
\n * \n * - \n *
\n * emailAddress – if the value specified is the email\n * address of an AWS account
\n * \n * Using email addresses to specify a grantee is only supported in the following AWS Regions:
\n * \n * For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the AWS General Reference.
\n * \n * \n *
\n * For example, the following x-amz-grant-read header grants the AWS accounts identified by account IDs permissions to read object data and its metadata:
\n * \n * x-amz-grant-read: id=\"11112222333\", id=\"444455556666\" \n *
\n * \n *

\n * \n * In this operation, you provide part data in your request. However, you have an option\n * to specify your existing Amazon S3 object as a data source for the part you are uploading. To\n * upload a part from an existing object, you use the UploadPartCopy operation.\n *
\n * \n *\n * You must initiate a multipart upload (see CreateMultipartUpload)\n * before you can upload any part. In response to your initiate request, Amazon S3 returns an\n * upload ID, a unique identifier, that you must include in your upload part request.
\n * Part numbers can be any number from 1 to 10,000, inclusive. A part number uniquely\n * identifies a part and also defines its position within the object being created. If you\n * upload a new part using the same part number that was used with a previous part, the\n * previously uploaded part is overwritten. Each part must be at least 5 MB in size, except\n * the last part. There is no size limit on the last part of your multipart upload.
\n * To ensure that data is not corrupted when traversing the network, specify the\n * Content-MD5 header in the upload part request. Amazon S3 checks the part data\n * against the provided MD5 value. If they do not match, Amazon S3 returns an error.
\n *\n * If the upload request is signed with Signature Version 4, then AWS S3 uses the\n * x-amz-content-sha256 header as a checksum instead of\n * Content-MD5. For more information see Authenticating Requests: Using the Authorization Header (AWS Signature Version\n * 4).
\n *\n *\n *\n * \n * Note: After you initiate multipart upload and upload\n * one or more parts, you must either complete or abort multipart upload in order to stop\n * getting charged for storage of the uploaded parts. Only after you either complete or abort\n * multipart upload, Amazon S3 frees up the parts storage and stops charging you for the parts\n * storage.
\n *\n * For more information on multipart uploads, go to Multipart Upload Overview in the\n * Amazon Simple Storage Service Developer Guide .
\n * For information on the permissions required to use the multipart upload API, go to\n * Multipart Upload API and\n * Permissions in the Amazon Simple Storage Service Developer Guide.
\n *\n * You can optionally request server-side encryption where Amazon S3 encrypts your data as it\n * writes it to disks in its data centers and decrypts it for you when you access it. You have\n * the option of providing your own encryption key, or you can use the AWS managed encryption\n * keys. If you choose to provide your own encryption key, the request headers you provide in\n * the request must match the headers you used in the request to initiate the upload by using\n * CreateMultipartUpload. For more information, go to Using Server-Side Encryption in\n * the Amazon Simple Storage Service Developer Guide.
\n *\n * Server-side encryption is supported by the S3 Multipart Upload actions. Unless you are\n * using a customer-provided encryption key, you don't need to specify the encryption\n * parameters in each UploadPart request. Instead, you only need to specify the server-side\n * encryption parameters in the initial Initiate Multipart request. For more information, see\n * CreateMultipartUpload.
\n *\n * If you requested server-side encryption using a customer-provided encryption key in your\n * initiate multipart upload request, you must provide identical encryption information in\n * each part upload using the following headers.

\n * You first initiate the multipart upload and then upload all parts using the UploadPart\n * operation. After successfully uploading all relevant parts of an upload, you call this\n * operation to complete the upload. Upon receiving this request, Amazon S3 concatenates all\n * the parts in ascending order by part number to create a new object. In the Complete\n * Multipart Upload request, you must provide the parts list. You must ensure that the parts\n * list is complete. This operation concatenates the parts that you provide in the list. For\n * each part in the list, you must provide the part number and the ETag value,\n * returned after that part was uploaded.
\n * Processing of a Complete Multipart Upload request could take several minutes to\n * complete. After Amazon S3 begins processing the request, it sends an HTTP response header that\n * specifies a 200 OK response. While processing is in progress, Amazon S3 periodically sends white\n * space characters to keep the connection from timing out. Because a request could fail after\n * the initial 200 OK response has been sent, it is important that you check the response body\n * to determine whether the request succeeded.
\n * Note that if CompleteMultipartUpload fails, applications should be prepared\n * to retry the failed requests. For more information, see Amazon S3 Error Best Practices.

Sometimes it's called a \"filter\",\n// but that's not a great name for it, since that implies a thing where\n// some bits pass through, and others are simply ignored. (That would\n// be a valid example of a transform, of course.)\n//\n// While the output is causally related to the input, it's not a\n// necessarily symmetric or synchronous transformation. For example,\n// a zlib stream might take multiple plain-text writes(), and then\n// emit a single compressed chunk some time in the future.\n//\n// Here's how this works:\n//\n// The Transform stream has all the aspects of the readable and writable\n// stream classes. When you write(chunk), that calls _write(chunk,cb)\n// internally, and returns false if there's a lot of pending writes\n// buffered up. When you call read(), that calls _read(n) until\n// there's enough pending readable data buffered up.\n//\n// In a transform stream, the written data is placed in a buffer. When\n// _read(n) is called, it transforms the queued up data, calling the\n// buffered _write cb's as it consumes chunks. If consuming a single\n// written chunk would result in multiple output chunks, then the first\n// outputted bit calls the readcb, and subsequent chunks just go into\n// the read buffer, and will cause it to emit 'readable' if necessary.\n//\n// This way, back-pressure is actually determined by the reading side,\n// since _read has to be called to start processing a new chunk. However,\n// a pathological inflate type of transform can cause excessive buffering\n// here. For example, imagine a stream where every byte of input is\n// interpreted as an integer from 0-255, and then results in that many\n// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in\n// 1kb of data being output. In this case, you could write a very small\n// amount of input, and end up with a very large amount of output. In\n// such a pathological inflating mechanism, there'd be no way to tell\n// the system to stop doing the transform. A single 4MB write could\n// cause the system to run out of memory.\n//\n// However, even in such a pathological case, only a single written chunk\n// would be consumed, and then the rest would wait (un-transformed) until\n// the results of the previous transformed chunk were consumed.\n'use strict';\n\nmodule.exports = Transform;\n\nvar _require$codes = require('../errors').codes,\n ERR_METHOD_NOT_IMPLEMENTED = _require$codes.ERR_METHOD_NOT_IMPLEMENTED,\n ERR_MULTIPLE_CALLBACK = _require$codes.ERR_MULTIPLE_CALLBACK,\n ERR_TRANSFORM_ALREADY_TRANSFORMING = _require$codes.ERR_TRANSFORM_ALREADY_TRANSFORMING,\n ERR_TRANSFORM_WITH_LENGTH_0 = _require$codes.ERR_TRANSFORM_WITH_LENGTH_0;\n\nvar Duplex = require('./_stream_duplex');\n\nrequire('inherits')(Transform, Duplex);\n\nfunction afterTransform(er, data) {\n var ts = this._transformState;\n ts.transforming = false;\n var cb = ts.writecb;\n\n if (cb === null) {\n return this.emit('error', new ERR_MULTIPLE_CALLBACK());\n }\n\n ts.writechunk = null;\n ts.writecb = null;\n if (data != null) // single equals check for both `null` and `undefined`\n this.push(data);\n cb(er);\n var rs = this._readableState;\n rs.reading = false;\n\n if (rs.needReadable || rs.length < rs.highWaterMark) {\n this._read(rs.highWaterMark);\n }\n}\n\nfunction Transform(options) {\n if (!(this instanceof Transform)) return new Transform(options);\n Duplex.call(this, options);\n this._transformState = {\n afterTransform: afterTransform.bind(this),\n needTransform: false,\n transforming: false,\n writecb: null,\n writechunk: null,\n writeencoding: null\n }; // start out asking for a readable event once data is transformed.\n\n this._readableState.needReadable = true; // we have implemented the _read method, and done the other things\n // that Readable wants before the first _read call, so unset the\n // sync guard flag.\n\n this._readableState.sync = false;\n\n if (options) {\n if (typeof options.transform === 'function') this._transform = options.transform;\n if (typeof options.flush === 'function') this._flush = options.flush;\n } // When the writable side finishes, then flush out anything remaining.\n\n\n this.on('prefinish', prefinish);\n}\n\nfunction prefinish() {\n var _this = this;\n\n if (typeof this._flush === 'function' && !this._readableState.destroyed) {\n this._flush(function (er, data) {\n done(_this, er, data);\n });\n } else {\n done(this, null, null);\n }\n}\n\nTransform.prototype.push = function (chunk, encoding) {\n this._transformState.needTransform = false;\n return Duplex.prototype.push.call(this, chunk, encoding);\n}; // This is the part where you do stuff!\n// override this function in implementation classes.\n// 'chunk' is an input chunk.\n//\n// Call `push(newChunk)` to pass along transformed output\n// to the readable side.

Sometimes it's called a \"filter\",\n// but that's not a great name for it, since that implies a thing where\n// some bits pass through, and others are simply ignored. (That would\n// be a valid example of a transform, of course.)\n//\n// While the output is causally related to the input, it's not a\n// necessarily symmetric or synchronous transformation. For example,\n// a zlib stream might take multiple plain-text writes(), and then\n// emit a single compressed chunk some time in the future.\n//\n// Here's how this works:\n//\n// The Transform stream has all the aspects of the readable and writable\n// stream classes. When you write(chunk), that calls _write(chunk,cb)\n// internally, and returns false if there's a lot of pending writes\n// buffered up. When you call read(), that calls _read(n) until\n// there's enough pending readable data buffered up.\n//\n// In a transform stream, the written data is placed in a buffer. When\n// _read(n) is called, it transforms the queued up data, calling the\n// buffered _write cb's as it consumes chunks. If consuming a single\n// written chunk would result in multiple output chunks, then the first\n// outputted bit calls the readcb, and subsequent chunks just go into\n// the read buffer, and will cause it to emit 'readable' if necessary.\n//\n// This way, back-pressure is actually determined by the reading side,\n// since _read has to be called to start processing a new chunk. However,\n// a pathological inflate type of transform can cause excessive buffering\n// here. For example, imagine a stream where every byte of input is\n// interpreted as an integer from 0-255, and then results in that many\n// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in\n// 1kb of data being output. In this case, you could write a very small\n// amount of input, and end up with a very large amount of output. In\n// such a pathological inflating mechanism, there'd be no way to tell\n// the system to stop doing the transform. A single 4MB write could\n// cause the system to run out of memory.\n//\n// However, even in such a pathological case, only a single written chunk\n// would be consumed, and then the rest would wait (un-transformed) until\n// the results of the previous transformed chunk were consumed.\n\n'use strict';\n\nmodule.exports = Transform;\n\nvar Duplex = require('./_stream_duplex');\n\n/**/\nvar util = Object.create(require('core-util-is'));\nutil.inherits = require('inherits');\n/**/\n\nutil.inherits(Transform, Duplex);\n\nfunction afterTransform(er, data) {\n var ts = this._transformState;\n ts.transforming = false;\n\n var cb = ts.writecb;\n\n if (!cb) {\n return this.emit('error', new Error('write callback called multiple times'));\n }\n\n ts.writechunk = null;\n ts.writecb = null;\n\n if (data != null) // single equals check for both `null` and `undefined`\n this.push(data);\n\n cb(er);\n\n var rs = this._readableState;\n rs.reading = false;\n if (rs.needReadable || rs.length < rs.highWaterMark) {\n this._read(rs.highWaterMark);\n }\n}\n\nfunction Transform(options) {\n if (!(this instanceof Transform)) return new Transform(options);\n\n Duplex.call(this, options);\n\n this._transformState = {\n afterTransform: afterTransform.bind(this),\n needTransform: false,\n transforming: false,\n writecb: null,\n writechunk: null,\n writeencoding: null\n };\n\n // start out asking for a readable event once data is transformed.\n this._readableState.needReadable = true;\n\n // we have implemented the _read method, and done the other things\n // that Readable wants before the first _read call, so unset the\n // sync guard flag.\n this._readableState.sync = false;\n\n if (options) {\n if (typeof options.transform === 'function') this._transform = options.transform;\n\n if (typeof options.flush === 'function') this._flush = options.flush;\n }\n\n // When the writable side finishes, then flush out anything remaining.\n this.on('prefinish', prefinish);\n}\n\nfunction prefinish() {\n var _this = this;\n\n if (typeof this._flush === 'function') {\n this._flush(function (er, data) {\n done(_this, er, data);\n });\n } else {\n done(this, null, null);\n }\n}\n\nTransform.prototype.push = function (chunk, encoding) {\n this._transformState.needTransform = false;\n return Duplex.prototype.push.call(this, chunk, encoding);\n};\n\n// This is the part where you do stuff!\n// override this function in implementation classes.\n// 'chunk' is an input chunk.\n//\n// Call `push(newChunk)` to pass along transformed output\n// to the readable side.

Sometimes it's called a \"filter\",\n// but that's not a great name for it, since that implies a thing where\n// some bits pass through, and others are simply ignored. (That would\n// be a valid example of a transform, of course.)\n//\n// While the output is causally related to the input, it's not a\n// necessarily symmetric or synchronous transformation. For example,\n// a zlib stream might take multiple plain-text writes(), and then\n// emit a single compressed chunk some time in the future.\n//\n// Here's how this works:\n//\n// The Transform stream has all the aspects of the readable and writable\n// stream classes. When you write(chunk), that calls _write(chunk,cb)\n// internally, and returns false if there's a lot of pending writes\n// buffered up. When you call read(), that calls _read(n) until\n// there's enough pending readable data buffered up.\n//\n// In a transform stream, the written data is placed in a buffer. When\n// _read(n) is called, it transforms the queued up data, calling the\n// buffered _write cb's as it consumes chunks. If consuming a single\n// written chunk would result in multiple output chunks, then the first\n// outputted bit calls the readcb, and subsequent chunks just go into\n// the read buffer, and will cause it to emit 'readable' if necessary.\n//\n// This way, back-pressure is actually determined by the reading side,\n// since _read has to be called to start processing a new chunk. However,\n// a pathological inflate type of transform can cause excessive buffering\n// here. For example, imagine a stream where every byte of input is\n// interpreted as an integer from 0-255, and then results in that many\n// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in\n// 1kb of data being output. In this case, you could write a very small\n// amount of input, and end up with a very large amount of output. In\n// such a pathological inflating mechanism, there'd be no way to tell\n// the system to stop doing the transform. A single 4MB write could\n// cause the system to run out of memory.\n//\n// However, even in such a pathological case, only a single written chunk\n// would be consumed, and then the rest would wait (un-transformed) until\n// the results of the previous transformed chunk were consumed.\n'use strict';\n\nmodule.exports = Transform;\n\nvar _require$codes = require('../errors').codes,\n ERR_METHOD_NOT_IMPLEMENTED = _require$codes.ERR_METHOD_NOT_IMPLEMENTED,\n ERR_MULTIPLE_CALLBACK = _require$codes.ERR_MULTIPLE_CALLBACK,\n ERR_TRANSFORM_ALREADY_TRANSFORMING = _require$codes.ERR_TRANSFORM_ALREADY_TRANSFORMING,\n ERR_TRANSFORM_WITH_LENGTH_0 = _require$codes.ERR_TRANSFORM_WITH_LENGTH_0;\n\nvar Duplex = require('./_stream_duplex');\n\nrequire('inherits')(Transform, Duplex);\n\nfunction afterTransform(er, data) {\n var ts = this._transformState;\n ts.transforming = false;\n var cb = ts.writecb;\n\n if (cb === null) {\n return this.emit('error', new ERR_MULTIPLE_CALLBACK());\n }\n\n ts.writechunk = null;\n ts.writecb = null;\n if (data != null) // single equals check for both `null` and `undefined`\n this.push(data);\n cb(er);\n var rs = this._readableState;\n rs.reading = false;\n\n if (rs.needReadable || rs.length < rs.highWaterMark) {\n this._read(rs.highWaterMark);\n }\n}\n\nfunction Transform(options) {\n if (!(this instanceof Transform)) return new Transform(options);\n Duplex.call(this, options);\n this._transformState = {\n afterTransform: afterTransform.bind(this),\n needTransform: false,\n transforming: false,\n writecb: null,\n writechunk: null,\n writeencoding: null\n }; // start out asking for a readable event once data is transformed.\n\n this._readableState.needReadable = true; // we have implemented the _read method, and done the other things\n // that Readable wants before the first _read call, so unset the\n // sync guard flag.\n\n this._readableState.sync = false;\n\n if (options) {\n if (typeof options.transform === 'function') this._transform = options.transform;\n if (typeof options.flush === 'function') this._flush = options.flush;\n } // When the writable side finishes, then flush out anything remaining.\n\n\n this.on('prefinish', prefinish);\n}\n\nfunction prefinish() {\n var _this = this;\n\n if (typeof this._flush === 'function' && !this._readableState.destroyed) {\n this._flush(function (er, data) {\n done(_this, er, data);\n });\n } else {\n done(this, null, null);\n }\n}\n\nTransform.prototype.push = function (chunk, encoding) {\n this._transformState.needTransform = false;\n return Duplex.prototype.push.call(this, chunk, encoding);\n}; // This is the part where you do stuff!\n// override this function in implementation classes.\n// 'chunk' is an input chunk.\n//\n// Call `push(newChunk)` to pass along transformed output\n// to the readable side.

The\n primary way of interacting with a promise is through its `then` method, which\n registers callbacks to receive either a promise's eventual value or the reason\n why the promise cannot be fulfilled.\n\n Terminology\n -----------\n\n - `promise` is an object or function with a `then` method whose behavior conforms to this specification.\n - `thenable` is an object or function that defines a `then` method.\n - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).\n - `exception` is a value that is thrown using the throw statement.\n - `reason` is a value that indicates why a promise was rejected.\n - `settled` the final resting state of a promise, fulfilled or rejected.\n\n A promise can be in one of three states: pending, fulfilled, or rejected.\n\n Promises that are fulfilled have a fulfillment value and are in the fulfilled\n state. Promises that are rejected have a rejection reason and are in the\n rejected state. A fulfillment value is never a thenable.\n\n Promises can also be said to *resolve* a value. If this value is also a\n promise, then the original promise's settled state will match the value's\n settled state. So a promise that *resolves* a promise that rejects will\n itself reject, and a promise that *resolves* a promise that fulfills will\n itself fulfill.\n\n\n Basic Usage:\n ------------\n\n ```js\n let promise = new Promise(function(resolve, reject) {\n // on success\n resolve(value);\n\n // on failure\n reject(reason);\n });\n\n promise.then(function(value) {\n // on fulfillment\n }, function(reason) {\n // on rejection\n });\n ```\n\n Advanced Usage:\n ---------------\n\n Promises shine when abstracting away asynchronous interactions such as\n `XMLHttpRequest`s.\n\n ```js\n function getJSON(url) {\n return new Promise(function(resolve, reject){\n let xhr = new XMLHttpRequest();\n\n xhr.open('GET', url);\n xhr.onreadystatechange = handler;\n xhr.responseType = 'json';\n xhr.setRequestHeader('Accept', 'application/json');\n xhr.send();\n\n function handler() {\n if (this.readyState === this.DONE) {\n if (this.status === 200) {\n resolve(this.response);\n } else {\n reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));\n }\n }\n };\n });\n }\n\n getJSON('/posts.json').then(function(json) {\n // on fulfillment\n }, function(reason) {\n // on rejection\n });\n ```\n\n Unlike callbacks, promises are great composable primitives.\n\n ```js\n Promise.all([\n getJSON('/posts'),\n getJSON('/comments')\n ]).then(function(values){\n values[0] // => postsJSON\n values[1] // => commentsJSON\n\n return values;\n });\n ```\n\n @class Promise\n @param {Function} resolver\n Useful for tooling.\n @constructor\n*/\n\nvar Promise = function () {\n function Promise(resolver) {\n this[PROMISE_ID] = nextId();\n this._result = this._state = undefined;\n this._subscribers = [];\n\n if (noop !== resolver) {\n typeof resolver !== 'function' && needsResolver();\n this instanceof Promise ? initializePromise(this, resolver) : needsNew();\n }\n }\n\n /**\n The primary way of interacting with a promise is through its `then` method,\n which registers callbacks to receive either a promise's eventual value or the\n reason why the promise cannot be fulfilled.\n ```js\n findUser().then(function(user){\n // user is available\n }, function(reason){\n // user is unavailable, and you are given the reason why\n });\n ```\n Chaining\n --------\n The return value of `then` is itself a promise. This second, 'downstream'\n promise is resolved with the return value of the first promise's fulfillment\n or rejection handler, or rejected if the handler throws an exception.\n ```js\n findUser().then(function (user) {\n return user.name;\n }, function (reason) {\n return 'default name';\n }).then(function (userName) {\n // If `findUser` fulfilled, `userName` will be the user's name, otherwise it\n // will be `'default name'`\n });\n findUser().then(function (user) {\n throw new Error('Found user, but still unhappy');\n }, function (reason) {\n throw new Error('`findUser` rejected and we're unhappy');\n }).then(function (value) {\n // never reached\n }, function (reason) {\n // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.\n // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.\n });\n ```\n If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.\n ```js\n findUser().then(function (user) {\n throw new PedagogicalException('Upstream error');\n }).then(function (value) {\n // never reached\n }).then(function (value) {\n // never reached\n }, function (reason) {\n // The `PedgagocialException` is propagated all the way down to here\n });\n ```\n Assimilation\n ------------\n Sometimes the value you want to propagate to a downstream promise can only be\n retrieved asynchronously. This can be achieved by returning a promise in the\n fulfillment or rejection handler. The downstream promise will then be pending\n until the returned promise is settled. This is called *assimilation*.\n ```js\n findUser().then(function (user) {\n return findCommentsByAuthor(user);\n }).then(function (comments) {\n // The user's comments are now available\n });\n ```\n If the assimliated promise rejects, then the downstream promise will also reject.\n ```js\n findUser().then(function (user) {\n return findCommentsByAuthor(user);\n }).then(function (comments) {\n // If `findCommentsByAuthor` fulfills, we'll have the value here\n }, function (reason) {\n // If `findCommentsByAuthor` rejects, we'll have the reason here\n });\n ```\n Simple Example\n --------------\n Synchronous Example\n ```javascript\n let result;\n try {\n result = findResult();\n // success\n } catch(reason) {\n // failure\n }\n ```\n Errback Example\n ```js\n findResult(function(result, err){\n if (err) {\n // failure\n } else {\n // success\n }\n });\n ```\n Promise Example;\n ```javascript\n findResult().then(function(result){\n // success\n }, function(reason){\n // failure\n });\n ```\n Advanced Example\n --------------\n Synchronous Example\n ```javascript\n let author, books;\n try {\n author = findAuthor();\n books = findBooksByAuthor(author);\n // success\n } catch(reason) {\n // failure\n }\n ```\n Errback Example\n ```js\n function foundBooks(books) {\n }\n function failure(reason) {\n }\n findAuthor(function(author, err){\n if (err) {\n failure(err);\n // failure\n } else {\n try {\n findBoooksByAuthor(author, function(books, err) {\n if (err) {\n failure(err);\n } else {\n try {\n foundBooks(books);\n } catch(reason) {\n failure(reason);\n }\n }\n });\n } catch(error) {\n failure(err);\n }\n // success\n }\n });\n ```\n Promise Example;\n ```javascript\n findAuthor().\n then(findBooksByAuthor).\n then(function(books){\n // found books\n }).catch(function(reason){\n // something went wrong\n });\n ```\n @method then\n @param {Function} onFulfilled\n @param {Function} onRejected\n Useful for tooling.\n @return {Promise}\n */\n\n /**\n `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same\n as the catch block of a try/catch statement.\n ```js\n function findAuthor(){\n throw new Error('couldn't find that author');\n }\n // synchronous\n try {\n findAuthor();\n } catch(reason) {\n // something went wrong\n }\n // async with promises\n findAuthor().catch(function(reason){\n // something went wrong\n });\n ```\n @method catch\n @param {Function} onRejection\n Useful for tooling.\n @return {Promise}\n */\n\n\n Promise.prototype.catch = function _catch(onRejection) {\n return this.then(null, onRejection);\n };\n\n /**\n `finally` will be invoked regardless of the promise's fate just as native\n try/catch/finally behaves\n \n Synchronous example:\n \n ```js\n findAuthor() {\n if (Math.random() > 0.5) {\n throw new Error();\n }\n return new Author();\n }\n \n try {\n return findAuthor();
