+## Description
+
+> File Upload widget with multiple file selection, drag&drop support, progress
+> bars, validation and preview images, audio and video for jQuery.
+> Supports cross-domain, chunked and resumable file uploads and client-side
+> image resizing.
+> Works with any server-side platform (PHP, Python, Ruby on Rails, Java,
+> Node.js, Go etc.) that supports standard HTML form file uploads.
+
+## Demo
+
+[Demo File Upload](https://blueimp.github.io/jQuery-File-Upload/)
+
+## Features
+
+- **Multiple file upload:**
+ Allows to select multiple files at once and upload them simultaneously.
+- **Drag & Drop support:**
+ Allows to upload files by dragging them from your desktop or file manager and
+ dropping them on your browser window.
+- **Upload progress bar:**
+ Shows a progress bar indicating the upload progress for individual files and
+ for all uploads combined.
+- **Cancelable uploads:**
+ Individual file uploads can be canceled to stop the upload progress.
+- **Resumable uploads:**
+ Aborted uploads can be resumed with browsers supporting the Blob API.
+- **Chunked uploads:**
+ Large files can be uploaded in smaller chunks with browsers supporting the
+ Blob API.
+- **Client-side image resizing:**
+ Images can be automatically resized on client-side with browsers supporting
+ the required JS APIs.
+- **Preview images, audio and video:**
+ A preview of image, audio and video files can be displayed before uploading
+ with browsers supporting the required APIs.
+- **No browser plugins (e.g. Adobe Flash) required:**
+ The implementation is based on open standards like HTML5 and JavaScript and
+ requires no additional browser plugins.
+- **Graceful fallback for legacy browsers:**
+ Uploads files via XMLHttpRequests if supported and uses iframes as fallback
+ for legacy browsers.
+- **HTML file upload form fallback:**
+ Allows progressive enhancement by using a standard HTML file upload form as
+ widget element.
+- **Cross-site file uploads:**
+ Supports uploading files to a different domain with cross-site XMLHttpRequests
+ or iframe redirects.
+- **Multiple plugin instances:**
+ Allows to use multiple plugin instances on the same webpage.
+- **Customizable and extensible:**
+ Provides an API to set individual options and define callback methods for
+ various upload events.
+- **Multipart and file contents stream uploads:**
+ Files can be uploaded as standard "multipart/form-data" or file contents
+ stream (HTTP PUT file upload).
+- **Compatible with any server-side application platform:**
+ Works with any server-side platform (PHP, Python, Ruby on Rails, Java,
+ Node.js, Go etc.) that supports standard HTML form file uploads.
+
+## Security
+
+⚠️ Please read the [VULNERABILITIES](VULNERABILITIES.md) document for a list of
+fixed vulnerabilities
+
+Please also read the [SECURITY](SECURITY.md) document for instructions on how to
+securely configure your Web server for file uploads.
+
+## Setup
+
+jQuery File Upload can be installed via [NPM](https://www.npmjs.com/):
+
+```sh
+npm install blueimp-file-upload
+```
+
+This allows you to include [jquery.fileupload.js](js/jquery.fileupload.js) and
+its extensions via `node_modules`, e.g:
+
+```html
+<script src="node_modules/blueimp-file-upload/js/jquery.fileupload.js"></script>
+```
+
+The widget can then be initialized on a file upload form the following way:
+
+```js
+$('#fileupload').fileupload();
+```
+
+For further information, please refer to the following guides:
+
+- [Main documentation page](https://github.com/blueimp/jQuery-File-Upload/wiki)
+- [List of all available Options](https://github.com/blueimp/jQuery-File-Upload/wiki/Options)
+- [The plugin API](https://github.com/blueimp/jQuery-File-Upload/wiki/API)
+- [How to setup the plugin on your website](https://github.com/blueimp/jQuery-File-Upload/wiki/Setup)
+- [How to use only the basic plugin.](https://github.com/blueimp/jQuery-File-Upload/wiki/Basic-plugin)
+
+## Requirements
+
+### Mandatory requirements
+
+- [jQuery](https://jquery.com/) v1.7+
+- [jQuery UI widget factory](https://api.jqueryui.com/jQuery.widget/) v1.9+
+ (included): Required for the basic File Upload plugin, but very lightweight
+ without any other dependencies from the jQuery UI suite.
+- [jQuery Iframe Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/jquery.iframe-transport.js)
+ (included): Required for
+ [browsers without XHR file upload support](https://github.com/blueimp/jQuery-File-Upload/wiki/Browser-support).
+
+### Optional requirements
+
+- [JavaScript Templates engine](https://github.com/blueimp/JavaScript-Templates)
+ v3+: Used to render the selected and uploaded files.
+- [JavaScript Load Image library](https://github.com/blueimp/JavaScript-Load-Image)
+ v2+: Required for the image previews and resizing functionality.
+- [JavaScript Canvas to Blob polyfill](https://github.com/blueimp/JavaScript-Canvas-to-Blob)
+ v3+:Required for the resizing functionality.
+- [blueimp Gallery](https://github.com/blueimp/Gallery) v2+: Used to display the
+ uploaded images in a lightbox.
+- [Bootstrap](https://getbootstrap.com/) v3+: Used for the demo design.
+- [Glyphicons](https://glyphicons.com/) Icon set used by Bootstrap.
+
+### Cross-domain requirements
+
+[Cross-domain File Uploads](https://github.com/blueimp/jQuery-File-Upload/wiki/Cross-domain-uploads)
+using the
+[Iframe Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/jquery.iframe-transport.js)
+require a redirect back to the origin server to retrieve the upload results. The
+[example implementation](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/main.js)
+makes use of
+[result.html](https://github.com/blueimp/jQuery-File-Upload/blob/master/cors/result.html)
+as a static redirect page for the origin server.
+
+The repository also includes the
+[jQuery XDomainRequest Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/cors/jquery.xdr-transport.js),
+which enables limited cross-domain AJAX requests in Microsoft Internet Explorer
+8 and 9 (IE 10 supports cross-domain XHR requests).
+The XDomainRequest object allows GET and POST requests only and doesn't support
+file uploads. It is used on the
+[Demo](https://blueimp.github.io/jQuery-File-Upload/) to delete uploaded files
+from the cross-domain demo file upload service.
+
+## Browsers
+
+### Desktop browsers
+
+The File Upload plugin is regularly tested with the latest browser versions and
+supports the following minimal versions:
+
+- Google Chrome
+- Apple Safari 4.0+
+- Mozilla Firefox 3.0+

+
+## Introduction
+
+For an in-depth understanding of the potential security risks of providing file
+uploads and possible mitigations, please refer to the
+[OWASP - Unrestricted File Upload](https://owasp.org/www-community/vulnerabilities/Unrestricted_File_Upload)
+documentation.
+
+To securely setup the project to serve uploaded files, please refer to the
+sample
+[Secure file upload serving configurations](#secure-file-upload-serving-configurations).
+
+To mitigate potential vulnerabilities in image processing libraries, please
+refer to the
+[Secure image processing configurations](#secure-image-processing-configurations).
+
+By default, all sample upload handlers allow only upload of image files, which
+mitigates some attack vectors, but should not be relied on as the only
+protection.
+
+Please also have a look at the
+[list of fixed vulnerabilities](VULNERABILITIES.md) in jQuery File Upload, which
+relates mostly to the sample server-side upload handlers and how they have been
+configured.
+
+## Purpose of this project
+
+Please note that this project is not a complete file management product, but
+foremost a client-side file upload library for [jQuery](https://jquery.com/).
+The server-side sample upload handlers are just examples to demonstrate the
+client-side file upload functionality.
+
+To make this very clear, there is **no user authentication** by default:
+
+- **everyone can upload files**
+- **everyone can delete uploaded files**
+
+In some cases this can be acceptable, but for most projects you will want to
+extend the sample upload handlers to integrate user authentication, or implement
+your own.
+
+It is also up to you to configure your web server to securely serve the uploaded
+files, e.g. using the
+[sample server configurations](#secure-file-upload-serving-configurations).
+
+## Mitigations against file upload risks
+
+### Prevent code execution on the server
+
+To prevent execution of scripts or binaries on server-side, the upload directory
+must be configured to not execute files in the upload directory (e.g.
+`server/php/files` as the default for the PHP upload handler) and only treat
+uploaded files as static content.
+
+The recommended way to do this is to configure the upload directory path to
+point outside of the web application root.
+Then the web server can be configured to serve files from the upload directory
+with their default static files handler only.
+
+Limiting file uploads to a whitelist of safe file types (e.g. image files) also
+mitigates this issue, but should not be the only protection.
+
+### Prevent code execution in the browser
+
+To prevent execution of scripts on client-side, the following headers must be
+sent when delivering generic uploaded files to the client:
+
+```
+Content-Type: application/octet-stream
+X-Content-Type-Options: nosniff
+```
+
+The `Content-Type: application/octet-stream` header instructs browsers to
+display a download dialog instead of parsing it and possibly executing script
+content e.g. in HTML files.
+
+The `X-Content-Type-Options: nosniff` header prevents browsers to try to detect
+the file mime type despite the given content-type header.
+
+For known safe files, the content-type header can be adjusted using a
+**whitelist**, e.g. sending `Content-Type: image/png` for PNG files.
+
+### Prevent distribution of malware
+
+To prevent attackers from uploading and distributing malware (e.g. computer
+viruses), it is recommended to limit file uploads only to a whitelist of safe
+file types.
+
+Please note that the detection of file types in the sample file upload handlers
+is based on the file extension and not the actual file content. This makes it
+still possible for attackers to upload malware by giving their files an image
+file extension, but should prevent automatic execution on client computers when
+opening those files.
+
+It does not protect at all from exploiting vulnerabilities in image display
+programs, nor from users renaming file extensions to inadvertently execute the
+contained malicious code.
+
+## Secure file upload serving configurations
+
+The following configurations serve uploaded files as static files with the
+proper headers as
+[mitigation against file upload risks](#mitigations-against-file-upload-risks).
+Please do not simply copy&paste these configurations, but make sure you
+understand what they are doing and that you have implemented them correctly.
+
+> Always test your own setup and make sure that it is secure!
+
+e.g. try uploading PHP scripts (as "example.php", "example.php.png" and
+"example.png") to see if they get executed by your web server, e.g. the content
+of the following sample:
+
+```php
+GIF89ad <?php echo mime_content_type(__FILE__); phpinfo();
+```
+
+### Apache config
+
+Add the following directive to the Apache config (e.g.
+/etc/apache2/apache2.conf), replacing the directory path with the absolute path
+to the upload directory:
+
+```ApacheConf
+<Directory "/path/to/project/server/php/files">
+ # Some of the directives require the Apache Headers module. If it is not
+ # already enabled, please execute the following command and reload Apache:
+ # sudo a2enmod headers
+ #
+ # Please note that the order of directives across configuration files matters,
+ # see also:
+ # https://httpd.apache.org/docs/current/sections.html#merging
+
+ # The following directive matches all files and forces them to be handled as
+ # static content, which prevents the server from parsing and executing files
+ # that are associated with a dynamic runtime, e.g. PHP files.
+ # It also forces their Content-Type header to "application/octet-stream" and
+ # adds a "Content-Disposition: attachment" header to force a download dialog,
+ # which prevents browsers from interpreting files in the context of the
+ # web server, e.g. HTML files containing JavaScript.
+ # Lastly it also prevents browsers from MIME-sniffing the Content-Type,
+ # preventing them from interpreting a file as a different Content-Type than
+ # the one sent by the webserver.
+ <FilesMatch ".*">
+ SetHandler default-handler
+ ForceType application/octet-stream
+ Header set Content-Disposition attachment
+ Header set X-Content-Type-Options nosniff
+ </FilesMatch>
+
+ # The following directive matches known image files and unsets the forced
+ # Content-Type so they can be served with their original mime type.
+ # It also unsets the Content-Disposition header to allow displaying them
+ # inline in the browser.
+ <FilesMatch ".+\.(?i:(gif|jpe?g|png))$">
+ ForceType none
+ Header unset Content-Disposition
+ </FilesMatch>
+</Directory>
+```
+
+### NGINX config
+
+Add the following directive to the NGINX config, replacing the directory path
+with the absolute path to the upload directory:
+
+```Nginx
+location ^~ /path/to/project/server/php/files {
+ root html;
+ default_type application/octet-stream;
+ types {
+ image/gif gif;
+ image/jpeg jpg;
+ image/png png;
+ }
+ add_header X-Content-Type-Options 'nosniff';
+ if ($request_filename ~ /(((?!\.(jpg)|(png)|(gif)$)[^/])+$)) {
+ add_header Content-Disposition 'attachment; filename="$1"';
+ # Add X-Content-Type-Options again, as using add_header in a new context
+ # dismisses all previous add_header calls:
+ add_header X-Content-Type-Options 'nosniff';
+ }
+}
+```
+
+## Secure image processing configurations
+
+The following configuration mitigates
+[potential image processing vulnerabilities with ImageMagick](VULNERABILITIES.md#potential-vulnerabilities-with-php-imagemagick)
+by limiting the attack vectors to a small subset of image types
+(`GIF/JPEG/PNG`).
+
+Please also consider using alternative, safer image processing libraries like
+[libvips](https://github.com/libvips/libvips) or
+[imageflow](https://github.com/imazen/imageflow).
+
+## ImageMagick config
+
+It is recommended to disable all non-required ImageMagick coders via
+[policy.xml](https://wiki.debian.org/imagemagick/security).
+To do so, locate the ImageMagick `policy.xml` configuration file and add the
+following policies:
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<!-- ... -->
+<policymap>
+ <!-- ... -->
+ <policy domain="delegate" rights="none" pattern="*" />
+ <policy domain="coder" rights="none" pattern="*" />
+ <policy domain="coder" rights="read | write" pattern="{GIF,JPEG,JPG,PNG}" />
+</policymap>
+```

+
+## Remote code execution vulnerability in the PHP component
+
+> Fixed: 2018-10-23 (GMT)
+
+The sample [PHP upload handler](server/php/UploadHandler.php) before
+[v9.24.1](https://github.com/blueimp/jQuery-File-Upload/releases/tag/v9.24.1)
+allowed to upload all file types by default.
+This opens up a remote code execution vulnerability, unless the server is
+configured to not execute (PHP) files in the upload directory
+(`server/php/files`).
+
+The provided [.htaccess](server/php/files/.htaccess) file includes instructions
+for Apache to disable script execution, however
+[.htaccess support](https://httpd.apache.org/docs/current/howto/htaccess.html)
+is disabled by default since Apache `v2.3.9` via
+[AllowOverride Directive](https://httpd.apache.org/docs/current/mod/core.html#allowoverride).
+
+**You are affected if you:**
+
+1. A) Uploaded jQuery File Upload < `v9.24.1` on a Webserver that executes files
+ with `.php` as part of the file extension (e.g. "example.php.png"), e.g.
+ Apache with `mod_php` enabled and the following directive (_not a recommended
+ configuration_):
+ ```ApacheConf
+ AddHandler php5-script .php
+ ```
+ B) Uploaded jQuery File Upload < `v9.22.1` on a Webserver that executes files
+ with the file extension `.php`, e.g. Apache with `mod_php` enabled and the
+ following directive:
+ ```ApacheConf
+ <FilesMatch \.php$>
+ SetHandler application/x-httpd-php
+ </FilesMatch>
+ ```
+2. Did not actively configure your Webserver to not execute files in the upload
+ directory (`server/php/files`).
+3. Are running Apache `v2.3.9+` with the default `AllowOverride` Directive set
+ to `None` or another Webserver with no `.htaccess` support.
+
+**How to fix it:**
+
+1. Upgrade to the latest version of jQuery File Upload.
+2. Configure your Webserver to not execute files in the upload directory, e.g.
+ with the [sample Apache configuration](SECURITY.md#apache-config)

+
+The sample Google App Engine upload handlers before
+v[9.10.1](https://github.com/blueimp/jQuery-File-Upload/releases/tag/9.10.1)
+accepted any URL as redirect target, making it possible to use the Webserver's
+domain for phishing attacks.

+## Cross-site scripting vulnerability in the Iframe Transport
+
+> Fixed: 2012-08-09 (GMT)
+
+The [redirect page](cors/result.html) for the
+[Iframe Transport](js/jquery.iframe-transport.js) before commit
+[4175032](https://github.com/blueimp/jQuery-File-Upload/commit/41750323a464e848856dc4c5c940663498beb74a)
+(_fixed in all tagged releases_) allowed executing arbitrary JavaScript in the
+context of the Webserver.

+ * contain `numKittens` so that the `equal` assertion can reference it when
+ * needed.
+ *
+ * - `message`: This flag contains an optional custom error message to be
+ * prepended to the error message that's generated by the assertion when it
+ * fails.
+ *
+ * - `ssfi`: This flag stands for "start stack function indicator". It
+ * contains a function reference that serves as the starting point for
+ * removing frames from the stack trace of the error that's created by the
+ * assertion when it fails. The goal is to provide a cleaner stack trace to
+ * end users by removing Chai's internal functions. Note that it only works
+ * in environments that support `Error.captureStackTrace`, and only when
+ * `Chai.config.includeStack` hasn't been set to `false`.
+ *
+ * - `lockSsfi`: This flag controls whether or not the given `ssfi` flag
+ * should retain its current value, even as assertions are chained off of
+ * this object. This is usually set to `true` when creating a new assertion
+ * from within another assertion. It's also temporarily set to `true` before

+ * The problem is that it creates uncertain expectations by asserting that the
+ * target object doesn't have all of `val`'s key/value pairs but may or may
+ * not have some of them. It's often best to identify the exact output that's

+ *
+ * When the target object isn't even expected to have `val`'s keys, it's
+ * often best to assert exactly that.

+ * expect({c: 3}).to.not.have.any.keys('a', 'b'); // Recommended
+ * expect({c: 3}).to.not.include({a: 1, b: 2}); // Not recommended

+ * asserting that each property doesn't have one of many unexpected values.
+ *
+ * expect({a: 3, b: 4}).to.include({a: 3, b: 4}); // Recommended
+ * expect({a: 3, b: 4}).to.not.include({a: 1, b: 2}); // Not recommended
+ *
+ * `.include` accepts an optional `msg` argument which is a custom error
+ * message to show when the assertion fails. The message can also be given as
+ * the second argument to `expect`.
+ *
+ * expect([1, 2, 3]).to.include(4, 'nooo why fail??');
+ * expect([1, 2, 3], 'nooo why fail??').to.include(4);
+ *
+ * `.include` can also be used as a language chain, causing all `.members` and
+ * `.keys` assertions that follow in the chain to require the target to be a
+ * superset of the expected set, rather than an identical set. Note that
+ * `.members` ignores duplicates in the subset when `.include` is added.

+ * // Target object's keys are a superset of ['a', 'b'] but not identical

+ * However, it's dangerous to negate `.throw` when providing any arguments.
+ * The problem is that it creates uncertain expectations by asserting that the

+ * different type than the given type, or that it throws an error of the given
+ * type but with a message that doesn't include the given string. It's often
+ * best to identify the exact output that's expected, and then write an
+ * assertion that only accepts that exact output.
+ *
+ * When the target isn't expected to throw an error, it's often best to assert
+ * exactly that.
+ *
+ * var goodFn = function () {};
+ *
+ * expect(goodFn).to.not.throw(); // Recommended
+ * expect(goodFn).to.not.throw(ReferenceError, 'x'); // Not recommended
+ *
+ * When the target is expected to throw an error, it's often best to assert

+ * expected string, rather than asserting that it doesn't have one of many
+ * unexpected types, and doesn't have a message that includes some string.
+ *
+ * var badFn = function () { throw new TypeError('Illegal salmon!'); };
+ *
+ * expect(badFn).to.throw(TypeError, 'salmon'); // Recommended
+ * expect(badFn).to.not.throw(ReferenceError, 'x'); // Not recommended
+ *
+ * `.throw` changes the target of any assertions that follow in the chain to
+ * be the error object that's thrown.
+ *
+ * var err = new TypeError('Illegal salmon!');
+ * err.code = 42;
+ * var badFn = function () { throw err; };
+ *
+ * expect(badFn).to.throw(TypeError).with.property('code', 42);
+ *
+ * `.throw` accepts an optional `msg` argument which is a custom error message
+ * to show when the assertion fails. The message can also be given as the
+ * second argument to `expect`. When not providing two arguments, always use
+ * the second form.
+ *
+ * var goodFn = function () {};
+ *
+ * expect(goodFn).to.throw(TypeError, 'x', 'nooo why fail??');
+ * expect(goodFn, 'nooo why fail??').to.throw();
+ *
+ * Due to limitations in ES5, `.throw` may not always work as expected when
+ * using a transpiler such as Babel or TypeScript. In particular, it may
+ * produce unexpected results when subclassing the built-in `Error` object and
+ * then passing the subclassed constructor to `.throw`. See your transpiler's
+ * docs for details:
+ *
+ * - ([Babel](https://babeljs.io/docs/usage/caveats/#classes))
+ * - ([TypeScript](https://github.com/Microsoft/TypeScript/wiki/Breaking-Changes#extending-built-ins-like-error-array-and-map-may-no-longer-work))
+ *
+ * Beware of some common mistakes when using the `throw` assertion. One common
+ * mistake is to accidentally invoke the function yourself instead of letting
+ * the `throw` assertion invoke the function for you. For example, when
+ * testing if a function named `fn` throws, provide `fn` instead of `fn()` as
+ * the target for the assertion.
+ *
+ * expect(fn).to.throw(); // Good! Tests `fn` as desired
+ * expect(fn()).to.throw(); // Bad! Tests result of `fn()`, not `fn`
+ *
+ * If you need to assert that your function `fn` throws when passed certain
+ * arguments, then wrap a call to `fn` inside of another function.
+ *
+ * expect(function () { fn(42); }).to.throw(); // Function expression
+ * expect(() => fn(42)).to.throw(); // ES6 arrow function
+ *
+ * Another common mistake is to provide an object method (or any stand-alone
+ * function that relies on `this`) as the target of the assertion. Doing so is
+ * problematic because the `this` context will be lost when the function is
+ * invoked by `.throw`; there's no way for it to know what `this` is supposed
+ * to be. There are two ways around this problem. One solution is to wrap the
+ * method or function call inside of another function. Another solution is to
+ * use `bind`.
+ *
+ * expect(function () { cat.meow(); }).to.throw(); // Function expression
+ * expect(() => cat.meow()).to.throw(); // ES6 arrow function
+ * expect(cat.meow.bind(cat)).to.throw(); // Bind
+ *
+ * Finally, it's worth mentioning that it's a best practice in JavaScript to
+ * only throw `Error` and derivatives of `Error` such as `ReferenceError`,
+ * `TypeError`, and user-defined objects that extend `Error`. No other type of
+ * value will generate a stack trace when initialized. With that said, the
+ * `throw` assertion does technically support any type of value being thrown,
+ * not just `Error` and its derivatives.

+
+// a transform stream is a readable/writable stream where you do
+// something with the data. Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored. (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation. For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes. When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up. When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer. 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.
