+# Commandline flags
+
+## Applying flags
+
+**Note:** this requires either a `userdebug` or `eng` Android build (you can
+check with `adb shell getprop ro.build.type`). Flags cannot be enabled on
+production builds of Android.
+
+WebView reads flags from a specific file during startup. To enable flags, write
+to the file with:
+
+```sh
+$ # Overwrites all flags (and prints the new flag state):
+$ build/android/adb_system_webview_command_line \
+    --show-composited-layer-borders \
+    --log-net-log=foo.json # Supports multiple flags
+$ # Simply prints the existing flag state):
+$ build/android/adb_system_webview_command_line
+$ # Passing empty string clears all flags:
+$ build/android/adb_system_webview_command_line ""
+```
+
+Or, you can use the `adb` in your `$PATH` like so:
+
+```sh
+$ FLAG_FILE=/data/local/tmp/webview-command-line
+$ adb shell "echo '_ --show-composited-layer-borders' > ${FLAG_FILE}"
+$ # The first token is ignored. We use '_' as a convenient placeholder, but any
+$ # token is acceptable.
+```
+
+**Note:** either set of commands will overwrite existing flags.
+
+### Applying Features with flags
+
+WebView supports the same `--enable-features=feature1,feature2` and
+`--disable-features=feature3,feature4` syntax as the rest of Chromium. You can
+use these like any other flag. Please consult
+[`base/feature_list.h`](https://cs.chromium.org/chromium/src/base/feature_list.h)
+for details.
+
+## Interesting flags
+
+WebView supports any flags supported in any layer we depend on (ex. content).
+Some interesting flags and Features:
+
+ * `--show-composited-layer-borders`
+ * `--enable-features=NetworkService,NetworkServiceInProcess`
+ * `--log-net-log=<filename.json>`
+
+WebView also defines its own flags and Features:
+
+ * [AwSwitches.java](https://cs.chromium.org/chromium/src/android_webview/java/src/org/chromium/android_webview/AwSwitches.java)
+   (and its [native
+   counterpart](https://cs.chromium.org/chromium/src/android_webview/common/aw_switches.h))
+ * [AwFeatureList.java](https://cs.chromium.org/chromium/src/android_webview/java/src/org/chromium/android_webview/AwFeatureList.java)
+   (and its [native
+   counterpart](https://cs.chromium.org/chromium/src/android_webview/browser/aw_feature_list.h))
+
+## Implementation
+
+See [CommandLineUtil.java](https://cs.chromium.org/chromium/src/android_webview/java/src/org/chromium/android_webview/command_line/CommandLineUtil.java).

+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

- * When a goog.module annotated file is loaded, it is enclosed in

- * - any variables declared in a goog.module file are private to the file
- * (not global), though the compiler is expected to inline the module.
- * - The code must obey all the rules of "strict" JavaScript.
- * - the file will be marked as "use strict"

- * @fileoverview Custom assertions to ensure that an element has the appropriate
- * type.
- *
- * Using a goog.dom.safe wrapper on an object on the incorrect type (via an
- * incorrect static type cast) can result in security bugs: For instance,
- * g.d.s.setAnchorHref ensures that the URL assigned to the .href attribute
- * satisfies the SafeUrl contract, i.e., is safe to dereference as a hyperlink.
- * However, the value assigned to a HTMLLinkElement's .href property requires
- * the stronger TrustedResourceUrl contract, since it can refer to a stylesheet.
- * Thus, using g.d.s.setAnchorHref on an (incorrectly statically typed) object
- * of type HTMLLinkElement can result in a security vulnerability.
- * Assertions of the correct run-time type help prevent such incorrect use.
- *
- * In some cases, code using the DOM API is tested using mock objects (e.g., a
- * plain object such as {'href': url} instead of an actual Location object).
- * To allow such mocking, the assertions permit objects of types that are not
- * relevant DOM API objects at all (for instance, not Element or Location).
- *
- * Note that instanceof checks don't work straightforwardly in older versions of
- * IE, or across frames (see,
- * http://stackoverflow.com/questions/384286/javascript-isdom-how-do-you-check-if-a-javascript-object-is-a-dom-object,
- * http://stackoverflow.com/questions/26248599/instanceof-htmlelement-in-iframe-is-not-element-or-object).
- *
- * Hence, these assertions may pass vacuously in such scenarios. The resulting
- * risk of security bugs is limited by the following factors:
- *  - A bug can only arise in scenarios involving incorrect static typing (the
- *    wrapper methods are statically typed to demand objects of the appropriate,
- *    precise type).
- *  - Typically, code is tested and exercised in multiple browsers.

- * @fileoverview Type-safe wrappers for unsafe DOM APIs.
- *
- * This file provides type-safe wrappers for DOM APIs that can result in
- * cross-site scripting (XSS) vulnerabilities, if the API is supplied with
- * untrusted (attacker-controlled) input.  Instead of plain strings, the type
- * safe wrappers consume values of types from the goog.html package whose
- * contract promises that values are safe to use in the corresponding context.
- *
- * Hence, a program that exclusively uses the wrappers in this file (i.e., whose
- * only reference to security-sensitive raw DOM APIs are in this file) is
- * guaranteed to be free of XSS due to incorrect use of such DOM APIs (modulo
- * correctness of code that produces values of the respective goog.html types,
- * and absent code that violates type safety).
- *
- * For example, assigning to an element's .innerHTML property a string that is
- * derived (even partially) from untrusted input typically results in an XSS
- * vulnerability. The type-safe wrapper goog.dom.safe.setInnerHtml consumes a
- * value of type goog.html.SafeHtml, whose contract states that using its values
- * in a HTML context will not result in XSS. Hence a program that is free of
- * direct assignments to any element's innerHTML property (with the exception of
- * the assignment to .innerHTML in this file) is guaranteed to be free of XSS
- * due to assignment of untrusted strings to the innerHTML property.

-/**
- * @fileoverview An event manager for both native browser event
- * targets and custom JavaScript event targets
- * ({@code goog.events.Listenable}). This provides an abstraction
- * over browsers' event systems.
- *
- * It also provides a simulation of W3C event model's capture phase in
- * Internet Explorer (IE 8 and below). Caveat: the simulation does not
- * interact well with listeners registered directly on the elements
- * (bypassing goog.events) or even with listeners registered via
- * goog.events in a separate JS binary. In these cases, we provide
- * no ordering guarantees.
- *
- * The listeners will receive a "patched" event object. Such event object
- * contains normalized values for certain event properties that differs in
- * different browsers.
- *
- * Example usage:
- * <pre>
- * goog.events.listen(myNode, 'click', function(e) { alert('woo') });
- * goog.events.listen(myNode, 'mouseover', mouseHandler, true);
- * goog.events.unlisten(myNode, 'mouseover', mouseHandler, true);
- * goog.events.removeAll(myNode);
- * </pre>

-// goog.events stores an auxiliary data structure on each EventTarget

-/**
- * @fileoverview This class aims to smooth out inconsistencies between browser

- * scrolling events that come in units of either pixels, lines or pages.

- * The significant difference here is that it also provides reasonable pixel
- * deltas for clients that do not want to treat line and page scrolling events
- * specially.
- *
- * Clients of this code should be aware that some input devices only fire a few
- * discrete events (such as a mouse wheel without acceleration) whereas some can
- * generate a large number of events for a single interaction (such as a
- * touchpad with acceleration). There is no signal in the events to reliably

-/**
- * @fileoverview Transitional utilities to unsafely trust random strings as
- * goog.html types. Intended for temporary use when upgrading a library that
- * used to accept plain strings to use safe types, but where it's not
- * practical to transitively update callers.
- *
- * IMPORTANT: No new code should use the conversion functions in this file,
- * they are intended for refactoring old code to use goog.html types. New code
- * should construct goog.html types via their APIs, template systems or
- * sanitizers. If that’s not possible it should use
- * goog.html.uncheckedconversions and undergo security review.
-
- * MOE:begin_intracomment_strip
- * At Google goog.html.legacyconversions are restricted via both BUILD
- * visibility and Conformance rules. The goal is to allow us to progressively
- * get rid of using strings to represent HTML-related data which is passed to
- * DOM APIs that execute script (like innerHTML or Anchor.href), while avoiding
- * regressions. Please carefully read the documentation below before using
- * these functions. If you have questions contact ise-hardening@ and we’ll
- * gladly help.
- * MOE:end_intracomment_strip
- *
- * The semantics of the conversions in goog.html.legacyconversions are very
- * different from the ones provided by goog.html.uncheckedconversions. The
- * latter are for use in code where it has been established through manual
- * security review that the value produced by a piece of code will always
- * satisfy the SafeHtml contract (e.g., the output of a secure HTML sanitizer).
- * In uses of goog.html.legacyconversions, this guarantee is not given -- the
- * value in question originates in unreviewed legacy code and there is no
- * guarantee that it satisfies the SafeHtml contract.
- *
- * There are only three valid uses of legacyconversions:
- *
- * 1. Introducing a goog.html version of a function which currently consumes
- * string and passes that string to a DOM API which can execute script - and
- * hence cause XSS - like innerHTML. For example, Dialog might expose a
- * setContent method which takes a string and sets the innerHTML property of
- * an element with it. In this case a setSafeHtmlContent function could be
- * added, consuming goog.html.SafeHtml instead of string, and using
- * goog.dom.safe.setInnerHtml instead of directly setting innerHTML.
- * setContent could then internally use legacyconversions to create a SafeHtml
- * from string and pass the SafeHtml to setSafeHtmlContent. In this scenario
- * remember to document the use of legacyconversions in the modified setContent
- * and consider deprecating it as well.
- *
- * 2. Automated refactoring of application code which handles HTML as string
- * but needs to call a function which only takes goog.html types. For example,
- * in the Dialog scenario from (1) an alternative option would be to refactor
- * setContent to accept goog.html.SafeHtml instead of string and then refactor
- * all current callers to use legacyconversions to pass SafeHtml. This is
- * generally preferable to (1) because it keeps the library clean of
- * legacyconversions, and makes code sites in application code that are
- * potentially vulnerable to XSS more apparent.
- *
- * 3. Old code which needs to call APIs which consume goog.html types and for
- * which it is prohibitively expensive to refactor to use goog.html types.
- * Generally, this is code where safety from XSS is either hopeless or
- * unimportant.

- * A SafeScript's string representation can safely be interpolated as the

- * and that carries the security type contract that its value, as a string,
- * will not cause untrusted script execution (XSS) when evaluated as CSS in a

- *
- * Instances of this type must be created via the factory methods
- * ({@code goog.html.SafeStyle.create} or

- * constructor. The constructor intentionally takes no parameters and the type
- * is immutable; hence only a default instance corresponding to the empty string
- * can be obtained via constructor invocation.
- *
- * SafeStyle's string representation can safely be:
- * <ul>
- *   <li>Interpolated as the content of a *quoted* HTML style attribute.
- *       However, the SafeStyle string *must be HTML-attribute-escaped* before
- *       interpolation.
- *   <li>Interpolated as the content of a {}-wrapped block within a stylesheet.
- *       '<' characters in the SafeStyle string *must be CSS-escaped* before
- *       interpolation. The SafeStyle string is also guaranteed not to be able
- *       to introduce new properties or elide existing ones.
- *   <li>Interpolated as the content of a {}-wrapped block within an HTML
- *       <style> element. '<' characters in the SafeStyle string
- *       *must be CSS-escaped* before interpolation.
- *   <li>Assigned to the style property of a DOM node. The SafeStyle string
- *       should not be escaped before being assigned to the property.
- * </ul>
- *
- * A SafeStyle may never contain literal angle brackets. Otherwise, it could
- * be unsafe to place a SafeStyle into a &lt;style&gt; tag (where it can't
- * be HTML escaped). For example, if the SafeStyle containing
- * "{@code font: 'foo &lt;style/&gt;&lt;script&gt;evil&lt;/script&gt;'}" were
- * interpolated within a &lt;style&gt; tag, this would then break out of the
- * style context into HTML.
- *
- * A SafeStyle may contain literal single or double quotes, and as such the
- * entire style string must be escaped when used in a style attribute (if
- * this were not the case, the string could contain a matching quote that
- * would escape from the style attribute).
- *
- * Values of this type must be composable, i.e. for any two values
- * {@code style1} and {@code style2} of this type,
- * {@code goog.html.SafeStyle.unwrap(style1) +
- * goog.html.SafeStyle.unwrap(style2)} must itself be a value that satisfies
- * the SafeStyle type constraint. This requirement implies that for any value
- * {@code style} of this type, {@code goog.html.SafeStyle.unwrap(style)} must
- * not end in a "property value" or "property name" context. For example,
- * a value of {@code background:url("} or {@code font-} would not satisfy the
- * SafeStyle contract. This is because concatenating such strings with a
- * second value that itself does not contain unsafe CSS can result in an
- * overall string that does. For example, if {@code javascript:evil())"} is
- * appended to {@code background:url("}, the resulting string may result in
- * the execution of a malicious script.
- *
- * TODO(mlourenco): Consider whether we should implement UTF-8 interchange
- * validity checks and blacklisting of newlines (including Unicode ones) and
- * other whitespace characters (\t, \f). Document here if so and also update
- * SafeStyle.fromConstant().

-/**
- * A string-like object which represents a CSS style sheet and that carries the
- * security type contract that its value, as a string, will not cause untrusted
- * script execution (XSS) when evaluated as CSS in a browser.
- *
- * Instances of this type must be created via the factory method
- * {@code goog.html.SafeStyleSheet.fromConstant} and not by invoking its
- * constructor. The constructor intentionally takes no parameters and the type
- * is immutable; hence only a default instance corresponding to the empty string
- * can be obtained via constructor invocation.
- *
- * A SafeStyleSheet's string representation can safely be interpolated as the
- * content of a style element within HTML. The SafeStyleSheet string should
- * not be escaped before interpolation.
- *
- * Values of this type must be composable, i.e. for any two values
- * {@code styleSheet1} and {@code styleSheet2} of this type,
- * {@code goog.html.SafeStyleSheet.unwrap(styleSheet1) +
- * goog.html.SafeStyleSheet.unwrap(styleSheet2)} must itself be a value that
- * satisfies the SafeStyleSheet type constraint. This requirement implies that
- * for any value {@code styleSheet} of this type,
- * {@code goog.html.SafeStyleSheet.unwrap(styleSheet1)} must end in
- * "beginning of rule" context.
-
- * A SafeStyleSheet can be constructed via security-reviewed unchecked
- * conversions. In this case producers of SafeStyleSheet must ensure themselves
- * that the SafeStyleSheet does not contain unsafe script. Note in particular
- * that {@code &lt;} is dangerous, even when inside CSS strings, and so should
- * always be forbidden or CSS-escaped in user controlled input. For example, if
- * {@code &lt;/style&gt;&lt;script&gt;evil&lt;/script&gt;"} were interpolated
- * inside a CSS string, it would break out of the context of the original
- * style element and {@code evil} would execute. Also note that within an HTML
- * style (raw text) element, HTML character references, such as
- * {@code &amp;lt;}, are not allowed. See

- * A string that is safe to use in URL context in DOM APIs and HTML documents.
- *
- * A SafeUrl is a string-like object that carries the security type contract
- * that its value as a string will not cause untrusted script execution
- * when evaluated as a hyperlink URL in a browser.
- *
- * Values of this type are guaranteed to be safe to use in URL/hyperlink
- * contexts, such as assignment to URL-valued DOM properties, in the sense that
- * the use will not result in a Cross-Site-Scripting vulnerability. Similarly,
- * SafeUrls can be interpolated into the URL context of an HTML template (e.g.,
- * inside a href attribute). However, appropriate HTML-escaping must still be
- * applied.
- *
- * Note that, as documented in {@code goog.html.SafeUrl.unwrap}, this type's
- * contract does not guarantee that instances are safe to interpolate into HTML
- * without appropriate escaping.
- *
- * Note also that this type's contract does not imply any guarantees regarding
- * the resource the URL refers to.  In particular, SafeUrls are <b>not</b>
- * safe to use in a context where the referred-to resource is interpreted as
- * trusted code, e.g., as the src of a script tag.
- *
- * Instances of this type must be created via the factory methods
- * ({@code goog.html.SafeUrl.fromConstant}, {@code goog.html.SafeUrl.sanitize}),
- * etc and not by invoking its constructor.  The constructor intentionally
- * takes no parameters and the type is immutable; hence only a default instance
- * corresponding to the empty string can be obtained via constructor invocation.

-/**
- * Utility class for formatting text for display in a potentially
- * opposite-directionality context without garbling. Provides the following
- * functionality:
- *
- * 1. BiDi Wrapping
- * When text in one language is mixed into a document in another, opposite-
- * directionality language, e.g. when an English business name is embedded in a
- * Hebrew web page, both the inserted string and the text following it may be
- * displayed incorrectly unless the inserted string is explicitly separated
- * from the surrounding text in a "wrapper" that declares its directionality at
- * the start and then resets it back at the end. This wrapping can be done in
- * HTML mark-up (e.g. a 'span dir="rtl"' tag) or - only in contexts where
- * mark-up can not be used - in Unicode BiDi formatting codes (LRE|RLE and PDF).
- * Providing such wrapping services is the basic purpose of the BiDi formatter.
- *
- * 2. Directionality estimation
- * How does one know whether a string about to be inserted into surrounding
- * text has the same directionality? Well, in many cases, one knows that this
- * must be the case when writing the code doing the insertion, e.g. when a
- * localized message is inserted into a localized page. In such cases there is
- * no need to involve the BiDi formatter at all. In the remaining cases, e.g.
- * when the string is user-entered or comes from a database, the language of
- * the string (and thus its directionality) is not known a priori, and must be
- * estimated at run-time. The BiDi formatter does this automatically.
- *
- * 3. Escaping
- * When wrapping plain text - i.e. text that is not already HTML or HTML-
- * escaped - in HTML mark-up, the text must first be HTML-escaped to prevent XSS
- * attacks and other nasty business. This of course is always true, but the
- * escaping can not be done after the string has already been wrapped in
- * mark-up, so the BiDi formatter also serves as a last chance and includes
- * escaping services.
- *
- * Thus, in a single call, the formatter will escape the input string as
- * specified, determine its directionality, and wrap it as necessary. It is
- * then up to the caller to insert the return value in the output.
- *
- * See http://wiki/Main/TemplatesAndBiDi for more information.
- *
- * @param {goog.i18n.bidi.Dir|number|boolean|null} contextDir The context
- *     directionality, in one of the following formats:

- *     2. A number (positive = LTR, negative = RTL, 0 = unknown).

- * @author jonp@google.com (Jon Perlow) Optimized for IE6
- *
- * This file contains an implementation of a Map structure. It implements a lot
- * of the methods used in goog.structs so those functions work on hashes. This
- * is best suited for complex key types. For simple keys such as numbers and
- * strings consider using the lighter-weight utilities in goog.object.
- * MOE:begin_intracomment_strip
- *
- * NOTE(flan): Internally, key types are NOT actually cast to
- * strings. Some people actually rely on this behavior even though it

- * NOTE(flan): Erik Corry (erikcorry) from the V8 team went over this
- * class with me to help look for simplifications and
- * optimizations. In the end, he didn't come up with very much. Erik
- * explained that "for (k in o)" is not optimized in Crankshaft
- * because it needs to look up properties in the whole prototype
- * chain. It also needs to return the keys in order. Thus keeping an
- * array of keys is actually much more efficient.
- *
- * Likewise, one option to iterate safely with "for (k in o)" is to
- * prefix the keys with some character, like ':'. This can create a
- * lot of strings that didn't exist before. In Closure Labs,
- * goog.labs.structs.Map uses extra arrays to store non-safe keys and
- * values.
- *
- * Thus, there are not a lot of reasonable simplifications that can be
- * done here without impacting performance.

-/**
- * @fileoverview Simple utilities for dealing with URI strings.
- *
- * This is intended to be a lightweight alternative to constructing goog.Uri
- * objects.  Whereas goog.Uri adds several kilobytes to the binary regardless
- * of how much of its functionality you use, this is designed to be a set of
- * mostly-independent utilities so that the compiler includes only what is
- * necessary for the task.  Estimated savings of porting is 5k pre-gzip and
- * 1.5k post-gzip.  To ensure the savings remain, future developers should
- * avoid adding new functionality to existing functions, but instead create
- * new ones and factor out shared code.
- *
- * Many of these utilities have limited functionality, tailored to common
- * cases.  The query parameter utilities assume that the parameter keys are
- * already encoded, since most keys are compile-time alphanumeric strings.  The
- * query parameter mutation utilities also do not tolerate fragment identifiers.
- *
- * By design, these functions can be slower than goog.Uri equivalents.
- * Repeated calls to some of functions may be quadratic in behavior for IE,
- * although the effect is somewhat limited given the 2kb limit.
- *
- * One advantage of the limited functionality here is that this approach is
- * less sensitive to differences in URI encodings than goog.Uri, since these
- * functions operate on strings directly, rather than decoding them and
- * then re-encoding.
- *
- * Uses features of RFC 3986 for parsing/formatting URIs:
- *   http://www.ietf.org/rfc/rfc3986.txt
- *
- * @author gboyer@google.com (Garrett Boyer) - The "lightened" design.

-/**
- * A regular expression for breaking a URI into its component parts.
- *
- * {@link http://www.ietf.org/rfc/rfc3986.txt} says in Appendix B
- * As the "first-match-wins" algorithm is identical to the "greedy"
- * disambiguation method used by POSIX regular expressions, it is natural and
- * commonplace to use a regular expression for parsing the potential five
- * components of a URI reference.
- *
- * The following line is the regular expression for breaking-down a
- * well-formed URI reference into its components.
- *
- * <pre>
- * ^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?
- *  12            3  4          5       6  7        8 9
- * </pre>
- *
- * The numbers in the second line above are only to assist readability; they
- * indicate the reference points for each subexpression (i.e., each paired
- * parenthesis). We refer to the value matched for subexpression <n> as $<n>.
- * For example, matching the above expression to
- * <pre>
- *     http://www.ics.uci.edu/pub/ietf/uri/#Related
- * </pre>
- * results in the following subexpression matches:
- * <pre>
- *    $1 = http:
- *    $2 = http
- *    $3 = //www.ics.uci.edu
- *    $4 = www.ics.uci.edu
- *    $5 = /pub/ietf/uri/
- *    $6 = <undefined>
- *    $7 = <undefined>
- *    $8 = #Related
- *    $9 = Related
- * </pre>
- * where <undefined> indicates that the component is not present, as is the
- * case for the query component in the above example. Therefore, we can
- * determine the value of the five components as
- * <pre>
- *    scheme    = $2
- *    authority = $4
- *    path      = $5
- *    query     = $7
- *    fragment  = $9
- * </pre>
- *
- * The regular expression has been modified slightly to expose the
- * userInfo, domain, and port separately from the authority.
- * The modified version yields
- * <pre>
- *    $1 = http              scheme
- *    $2 = <undefined>       userInfo -\
- *    $3 = www.ics.uci.edu   domain     | authority
- *    $4 = <undefined>       port     -/
- *    $5 = /pub/ietf/uri/    path
- *    $6 = <undefined>       query without ?
- *    $7 = Related           fragment without #
