Rhino Debugger
controlling execution the debugger provides the following facilities for you to control the execution of scripts you are debugging: step into to single step entering any function calls, you may do any of the following: select the debug->step into menu item on the menu bar press the step into button on the toolbar press the f11 key on the keyboard execution will resume.
... step over to single step to the next line in the current function, you may do any of the following: select the debug->step over menu item on the menu bar press the step over button on the toolbar press the f7 key on the keyboard execution will resume but control will return to the debugger at the next line in the current function or top-level script.
... step out to continue execution until the current function returns you may do any of the following: select the debug->step out menu item on the menu bar press the step out button on the toolbar press the f8 key on the keyboard execution will resume until the current function returns or a breakpoint is hit.
... go to resume execution of a script you may do any of the following: select the debug->go menu item on the menu bar press the go button on the toolbar press the f5 key on the keyboard execution will resume until a breakpoint is hit or the script completes.

Using IndexedDB - Web APIs

...since such catastrophic events are rare most consumers should not need to concern themselves further.
...when the request is finished you'll get a dom event and, assuming that the request succeeded, you'll have another opportunity to extend the transaction during that callback.
...here's how you can shorten it up a bit, assuming that you handle errors at the database level: db.transaction("customers").objectstore("customers").get("444-44-4444").onsuccess = function(event) { console.log("name for ssn 444-44-4444 is " + event.target.result.name); }; see how this works?

...since a response body cannot be consumed more than once, and a stream can't be read by more than one reader at once, you’d need two copies to do this.
... to use backpressure in a readablestream, we can ask the controller for the chunk size desired by the consumer by querying the readablestreamdefaultcontroller.desiredsize property on the controller.
... if later on the consumer again wants to receive data, we can use the pull method in the stream creation to tell our underlying source to feed our stream with data.

Rendering and the WebXR frame animation callback - Web APIs

...we can use this value while drawing the scene to ensure we move everything the appopriate distance given the true elapsed time, rather than assuming that the callback will be fired at a consistent frame rate.
...because the execution of your callback is not going to happen at precise 1/60th of a second intervals—and, indeed, could happen at other rates if the user's display has a different framer ate—you can't rely on the simple fact that your code is running to assume that it's been 1/60th of a second since the last frame.

await - JavaScript
description the await expression causes async function execution to pause until a promise is settled (that is, fulfilled or rejected), and to resume execution of the async function after fulfillment.
... when resumed, the value of the await expression is that of the fulfilled promise.
... an await can split execution flow, allowing the caller of the await's function to resume execution before the deferred continuation of the await's function.
... after the await defers the continuation of its function, if this is the first await executed by the function, immediate execution also continues by returning to the function's caller a pending promise for the completion of the await's function and resuming execution of that caller.

Strict mode - JavaScript
assignments, which would accidentally create global variables, instead throw an error in strict mode: 'use strict'; // assuming no global variable mistypedvariable exists mistypevariable = 17; // this line throws a referenceerror due to the // misspelling of variable second, strict mode makes assignments which would otherwise silently fail to throw an exception.
...still, this hiding makes little sense and is probably undesirable (it might hide a typo, for example), so in strict mode duplicate argument names are a syntax error: function sum(a, a, c) { // !!!
...a leading zero syntax for the octals is rarely useful and can be mistakenly used, so strict mode makes it a syntax error: 'use strict'; var sum = 015 + // !!!

Mozilla accessibility architecture
accessibility apis on each operating system have built-in assumptions about what is the most important information, and how an accessibility server like mozilla should use the api's programmatic interfaces to expose this information to an accessibility client (the assistive technology).
... each platform's accessibility api has made different assumptions, although there are a number of common characteristics.
...we cannot assume that all of the accessible children will come from the direct children, grandchildren or even great-great-great-children of the current accessible's node.

HTML parser threading
this way, the queues into which tree ops are produced and the queues from which they are consumed don't need to involve a mutex on each modification.
...that method is responsible for moving back to consuming tree ops from the parser thread via the staging area.) document.write() calls to document.write() push data to the tokenizer/tree builder pair that exists on the main thread solely for parsing data from document.write().
...when parseuntilblocked() exhausts the data available to it, it calls nshtml5streamparser::continueafterscripts to resume the consumption of data from the network.

Geckoview-Junit Tests
tests can also be conditionally skipped using junit's assume or assumethat methods.
... for example: import org.junit.assume.assumethat ...

NetUtil.jsm
the callback may then consume data from the input stream passed to the callback.
... example this example shows the basic code consumers would need to implement to be correct.

Examples
"you have file.txt in your temporary directory." : "you don't have file.txt in your temporary directory."); }).then(null, components.utils.reporterror); chaining promises the promise returned by then eventually assumes the state of the promise returned by the callback.
...newpromise.then(null, components.utils.reporterror); note: more examples for consuming promises are available in the promise object documentation.
... warning: when consuming promises, you should always handle or report errors (rejection reasons).

SourceMap.jsm
get a reference to the module: let sourcemap = {}; components.utils.import('resource:///modules/devtools/sourcemap.jsm', sourcemap); sourcemapconsumer a sourcemapconsumer instance represents a parsed source map which we can query for information about the original file positions by giving it a file position in the generated source.
... new sourcemapconsumer(rawsourcemap) the only parameter is the raw source map (either as a string which can be json.parse'd, or an object).
... sourcemapconsumer.prototype.originalpositionfor(generatedposition) returns the original source, line, and column information for the generated source's line and column positions provided.

Sqlite.jsm
consumers of this api can call the cancel function should they want to immediately abort the execution of the statement.

... conn.executetransaction(async function simpletransaction() { await conn.execute("insert into mytable values (?, ?)", ["foo", "bar"]); await conn.execute("insert into mytable values (?, ?)", ["biz", "baz"]); }); the above will result in 2 insert statements being committed in a deferred transaction (assuming the inserts proceed without error, of course).

Localization content best practices
create localizable strings don't assume grammar structures you need to consider the need for different grammar structures in different locales, and add switching mechanisms to present them appropriately.
... you shouldn't make assumptions as to what those structures will be: instead, let locales/localizers decide.
... splitting splitting sentences into several keys often inadvertently presumes a grammar, a sentence structure, and such composite strings are often very difficult to translate.

EventTarget.addEventListener() - Web APIs
because older browsers (as well as some not-too-old browsers) still assume the third parameter is a boolean, you need to build your code to handle this scenario intelligently.
...in the second case, the same previously declared function is used as an event handler, which results in smaller memory consumption because there is only one handler function created.

WebGL best practices - Web APIs

...assume that the memory usage of depth and stencil formats is rounded up to the nearest four bytes.

Starting up and shutting down a WebXR session - Web APIs
assuming you're already familiar with 3d graphics in general and webgl in particular, taking that next bold step into mixed reality—the idea of presenting artificial scenery or objects in addition to or in place of the real world—is not overly complicated.
... here we define a getxr() function, which returns the xrsystem object after optionally installing the polyfill, assuming that the polyfill has been included or loaded using a prior <script> tag.
...presumably the renderer uses this value to compute how often to render new frames as the animation loop progresses, thus rendering less frequently the more "blurred" the scene becomes.

Web Audio API best practices - Web APIs
autoplay policy browsers have started to implement an autoplay policy, which in general can be summed up as: "create or resume context from inside a user gesture".
...we can use the same click event example here, test for the state of the context and start it, if it is suspended, using the resume() method.
... const audioctx = new audiocontext(); const button = document.queryselector('button'); button.addeventlistener('click', function() { // check if context is in suspended state (autoplay policy) if (audioctx.state === 'suspended') { audioctx.resume(); } }, false); you might instead be working with an offlineaudiocontext, in which case you can resume the suspended audio context with the startrendering() method.

Web Authentication API - Web APIs
assuming that the checks pan out, the server will store the new public key associated with the user's account for future use -- that is, whenever the user desires to use the public key for authentication.
...assuming both of those steps are successful, the authenticator will create a new assertion by signing over the clientdatahash and authenticatordata with the private key generated for this account during the registration call.
...assuming the validation is successful, the server will note that the user is now authenticated.

Window.openDialog() - Web APIs
window.opendialog() finds it useful because of its different default assumptions.
... default behavior the chrome and dialog features are always assumed on, unless explicitly turned off ("chrome=no").
...if the features parameter is a zero-length string, or contains only one or more of the behavior features (chrome, dependent, dialog and modal) the chrome features are assumed "os' choice." that is, window creation code is not given specific instructions, but is instead allowed to select the chrome that best fits a dialog on that operating system.

window.postMessage() - Web APIs
example /* * in window a's scripts, with a being on <http://example.com:8080>: */ var popup = window.open(/* popup details */); // when the popup has fully loaded, if not blocked by a popup blocker: // this does nothing, assuming the window hasn't changed its location.
... popup.postmessage("the user is 'bob' and the password is 'secret'", "https://secure.example.net"); // this will successfully queue a message to be sent to the popup, assuming // the window hasn't changed its location.
... if (event.origin !== "http://example.com:8080") return; // event.source is window.opener // event.data is "hello there!" // assuming you've verified the origin of the received message (which // you must do in any case), a convenient idiom for replying to a // message is to call postmessage on event.source and provide // event.origin as the targetorigin.

XRView - Web APIs
in other words, don't assume there are exactly two views on a given viewer; there can be as few as one (such as when rendering the scene in inline mode, and potentially many (especially if the field of view is very large).
...so you should process the view list every time without making assumptions based on previous frames.
... if in the future it becomes possible for each view to render into a different layer, there would have to be changes made to the api, so it's safe for now to assume that all views will render into the same layer.

ARIA: application role - Accessibility
in this mode, the web author is completely responsible for handling any and all keyboard input, focus management, and other interactions and cannot assume assistive technologies would do any processing on their end.

... for all of this to work, ats intercept almost all keyboard input and consume it themselves, letting nothing through to the browser or other user agent.

Text labels and names - Accessibility
if the title is not available, they have to navigate the page to determine its content, which can be a time consuming and potentially confusing process.

Block and inline layout in normal flow - CSS: Cascading Style Sheets
by default block elements will consume all of the space in the inline direction, so our paragraphs spread out and get as big as they can inside their containing block.
...this means that if you have an element with a top margin immediately after an element with a bottom margin, rather than the total space being the sum of these two margins, the margin collapses, and so will essentially become as large as the larger of the two margins.
... summary in this guide, we have looked at how elements display in normal flow, as block and inline elements.

... in the last example, the sum of both percentages is not 100%, and therefore both images include their respective opacities.
...the original syntax, which has been implemented in some browsers, only allowed for two images, with the sum of the transparency of those two images being exactly 100%.

parseInt() - JavaScript
if radix is undefined, 0, or unspecified, javascript assumes the following: if the input string begins with "0x" or "0x" (a zero, followed by lowercase or uppercase x), radix is assumed to be 16 and the rest of the string is parsed as a hexidecimal number.
... if the input string begins with "0" (a zero), radix is assumed to be 8 (octal) or 10 (decimal).
...if radix is undefined or 0, it is assumed to be 10 except when the number begins with the character pairs 0x or 0x, in which case a radix of 16 is assumed.

Subresource Integrity - Web security
tools for generating sri hashes you can generate sri hashes from the command-line with openssl using a command invocation such as this: cat filename.js | openssl dgst -sha384 -binary | openssl base64 -a or with shasum using a command invocation such as this: shasum -b -a 384 filename.js | awk '{ print $1 }' | xxd -r -p | base64 notes: the pipe-through-xxd step takes the hexadecimal output from shasum and converts it to binary.
... the pipe-through-awk step is necessary because shasum will pass the hashed filename in its output to xxd.
...therefore, the resource must be served with an access-control-allow-origin header that allows the resource to be shared with the requesting origin; for example: access-control-allow-origin: * examples in the following examples, assume that oqvuafxrkap7fdgccy5uykm6+r9gqq8k/uxy9rx7hnqlgyl1kpzqho1wx4jwy8wc is already known to be the expected sha-384 hash (digest) of a particular script example-framework.js, and there’s a copy of the script hosted at https://example.com/example-framework.js.

let's fix this problem by running the code once the load event has been fired — remove the console.log() line, and update this code block: let superheroes = request.response; populateheader(superheroes); showheroes(superheroes); to the following: request.onload = function() { let superheroes = request.response; populateheader(superheroes); showheroes(superheroes); } to summarize, anytime something is not working and a value does not appear to be what it is meant to be at some point in your code, you can use console.log() to print it out and see what is happening.
... summary so that's javascript.

Deploying our app - Learn web development
summary that's it for our sample case study, and for the module!
... let's summarise all the parts of the toolchain: code quality and maintenance are performed by eslint and prettier.

Accessibility information for UI designers and developers
your content can then be better consumed by users with low vision and people with color deficiencies.
...that way, users of screen readers and screen magnifiers can reliably make assumptions about them and skip over them.

Mozilla Plugin Accessibility
all browser keys unavailable when plugin has focus focused plugins currently have no choice but to consume all keyboard events.
...if the plugin needs those keystrokes, the can consume them and not pass them on.

Adding a new CSS property
this document assumes that you have a specifcation for the property available.
... (note that when the longhand property css_property_parse_value_list, the shorthand property parser would be assumed to be reusing the longhand parser once per item, not for a whole list, as for properties like background-image or transform-timing-function.) if the property takes a list of keywords other than inherit/initial/etc., auto, none, or normal (which can be expressed using the variant_* flags), you should use variant_keyword and add a keyword table to the nscssprops class.

What to do and what not to do in Bugzilla
changing the bug information fields summary you should change the summary if the current one is unclear or does not correctly describe the issue covered by the bug.
... you should not change the summary in order to morph the bug to describe a different issue.

Creating reftest-based unit tests
for example, it occurs to me that we assume that spaces between a element name and an attribute name have no effect, but do we know this is true?
...presumably, one was supposed to open the pages with a browser and look at them and see if they look right.

Configuring Build Options
this will also help when troubleshooting because people will want to know which build options you have selected and will assume that you have put them in your mozconfig file.
...this saves a considerable amount of time directly after a clobber build, so pulling in new updates and rebasing is less time-consuming.

The Firefox codebase: CSS Guidelines
other tips assume ="true" in attribute selectors.
... colors for common areas of the firefox interface (panels, toolbar buttons, etc.), mozilla-central often comes with some useful css variables that are adjusted with the correct values for different platform configurations, so using those css variables can definitively save some testing time, as you can assume they already work correctly.

Eclipse CDT Manual Setup
(this assumes that you already have a copy of the mozilla source, and that you have also built the source so that you have a pre-existing object directory.
... assuming everything went as expected, you should now find that eclipse's code assistance works a whole lot better.

Reviewer Checklist
assume that inputs will be too big, too short, empty, malformed, or malicious.
... documentation the commit message should describe what the patch is changing (not be a copy of the bug summary).

Cross Process Object Wrappers
converting synchronous code to be asynchronous can be difficult and time-consuming.
... message ordering cpows can violate assumptions you might make about message ordering.

mozbrowseractivitydone
the mozbrowseractivitydone event is fired when something inside the browser <iframe> triggers a web activity, and that web activity's message is consumed by the receiving app.
... if the activity has a returnvalue set to true, then the activity is consumed when postresult or posterror is invoked on the activity by the receiving app.

Getting Started with Chat
channels here is a list of channels you should be aware of as a member of the mozilla community: (remember to use irc.mozilla.org and port 6697 or 6667 for your server settings) #qa a channel for qa discussion #developers a channel for mozilla development discussion #sumo a channel for support with firefox for more information about the mozilla irc network and more channels, go here.
...the following are some helpful commands which can be used by firebot: bug ###### when a bug number is mentioned in a message, firebot automatically displays the link and summary from bugzilla for that bug.

IPDL Tutorial
a quick summary of the difference between rpc and sync semantics is that rpc allows "re-entrant" message handlers: while an actor is blocked waiting for an "answer" to an rpc "call", it can be unblocked to handle a new, incoming rpc call.
... given the simple protocols: // --- pexample.ipdl include protocol psubexample; async protocol pexample { manages psubexample; parent: async pchild(); }; // --- psubexample.ipdl include protocol pexample; async protocol psubexample { manager pexample; child: async __delete__(); }; we assume that there is a psubexampleparent/child pair in existence, such that some element now wishes to trigger the protocol's deletion from the parent side.

JavaScript-DOM Prototypes in Mozilla
all the methods that are supposed to show up on this jsobject are actually not properties of the object itself, but rather properties of the prototype of the jsobject for the wrapper (unless the c++ object's class info has the flag nsixpcscriptable::dont_share_prototype set, but lets assume that's not the case here).
...because of this, the following holds true (assuming img1 and img2 are two different image objects in the same document): img1.__proto__ === img2.__proto__ if img1 would come from one document and img2 from another document, then the above would not be true.

Promise
return value a new promise that is initially pending, then assumes a state that depends on the outcome of the invoked callback function: if the callback returns a value that is not a promise, including undefined, the new promise is fulfilled with this fulfillment value, even if the original promise was rejected.
... if the callback returns a promise, the new promise will eventually assume the same state as the returned promise.

PromiseWorker.jsm
summary a promiseworker is a chromeworker except instead of calling postmessage() to send a message, you call post(), which returns a promise.
...in summary, from a worker file, data can only be sent back as a response to a request from the main thread, it is not possible for a worker to send data to the main thread otherwise, this is a key difference between promiseworker worker file and all other types of workers.

Application Translation with Mercurial

...the output closes with a summary, giving the total counts of missing and obsolete strings and some statistics on how many strings are changed or not, excluding access and command keys.

Localization and Plurals
t plural form of a word based on the number * * @param anum * the number to decide which plural form to use * @param awords * a semi-colon (;) separated string of words to pick the plural form * @return the appropriate plural form of the word */ string pluralform get(int anum, string awords) here is an example of using this method: // load pluralform and for this example, assume english components.utils.import("resource://gre/modules/pluralform.jsm"); // pluralform.get expects a semi-colon separated list of words let downloads = "download;downloads"; // pretend this number came from somewhere else let num = 10; // display the correct plural form for 10 downloads: "you have 10 downloads.") print("you have " + num + " " + pluralform.get(num, downloads) + "."); // try a...
...gain with a different value: "you have 1 download." num = 1; print("you have " + num + " " + pluralform.get(num, downloads) + ".") the above example works, but is still difficult to localize, because we're concatenating strings assuming a particular grammatical structure.

Localizing with Mozilla Translator
let's assume you have a firefox product in mt with the directory layout present in language packs, as you probably would need for a initial localization.
... ; assuming we are in a directory containing mozilla-central/ $ mkdir locale-only $ cd locale-only $ mkdir -p browser extensions/reporter other-licenses/branding/firefox/ $ cd browser; ln -s ../../mozilla-central/browser/locales/; cd ..

Mozilla Development Strategies
you can still land (assuming you get reviews) if the code isn't on by default.
... make sure you have the right fix when you go for reviews when tempted to do a first pass fix and fix the fallout later, do it right the first time; don't assume you'll be able to file a "fix it" bug and fix stuff you know about later -- chances are the reviewer will make you do the work anyway.

Gecko Profiler FAQ

...summary: leaked 13 out of 15 dom windows leaked 35 out of 46 documents leaked 4 out of 4 docshells leaked content nodes in 42 out of 53 documents if you see such a results, please file a bug.

Memory reporting
in this case it's often clearer to increment the numbers rather than assigning to them, especially if you're measuring multiple entities and summing their measurements.
...but often you'll have a singleton object that needs measuring, in which case it is usually better not to have a separate reporter object, but instead for the singleton object to implement nsimemoryreporter, and thus measure and report its own memory consumption.

A brief guide to Mozilla preferences
a preference is any value or defined behavior that can be set (presumably, one setting is preferable to another).
...for example, let's assume that nightly has a preference "some.preference" which defaults to true while developeredition defaults the same preference to false and the user desires the preference to have the value true in both channels.

NSPR's Position On Abrupt Thread Termination
abrupt termination has been available in the unix/c environment for some time (exit()), and i assume that the basic semantics defined there are applicable here.
...if they cannot, because of some state corruption, then they must assume that the corruption, like the state, is shared, and their only resource is for the process to terminate.

PR_CWait
the thread waiting on the monitor resumes execution when the monitor is notified (assuming the thread is the next in line to receive the notify) or when the interval specified in the timeout parameter has been exceeded.
... when the thread resumes execution, it is the caller's responsibility to test the state of the monitored data to determine the appropriate action.

PR_SetErrorText
if not null, and if text is zero, the string is assumed to be a null-terminated c string.
... otherwise the text is assumed to be the length specified and to possibly include null characters (as might occur in a multilingual string).

PR_WaitCondVar
timeout the value pr_interval_no_timeout requires that a condition be notified (or the thread interrupted) before it will resume from the wait.
... the value pr_interval_no_wait causes the thread to release the lock, possibly causing a rescheduling within the runtime, then immediately attempt to reacquire the lock and resume.

... restricting ciphers by default, sslstrength assumes that all the preferences are on, so it will use any preferences in your policy.

PKCS11 FAQ
(many nss based server products will use temporary session objects, even for "private key op only" tokens.) if a session key is unwrapped and stays on a hardware token, is it sufficient to support just the usual decryption mechanisms for it, or is it assumed that such a symmetric key will always be extractable from the token into the browser?
...is it safe to assume that nss never calls c_createobject for those persistent objects?

FC_GetSessionInfo
a user may call fc_getsessioninfo without logging into the token (to assume the nss user role).
...otherwise, it fills in the ck_session_info structure with the following information: state: the state of the session, i.e., no role is assumed, the user role is assumed, or the crypto officer role is assumed flags: bit flags that define the type of session ckf_rw_session (0x00000002): true if the session is read/write; false if the session is read-only.

Performance Hints
for example, you could rewrite function sum(a) { result = 0; for (i=0; i < a.length; i++) result += a[i]; return result; } as function sum(a) { var result = 0; for (var i=0; i < a.length; i++) result += a[i]; return result; } this is not equivalent code because the second version does not modify global variables result and i.
... however, if you don't intend for any other function to access these variables, then storing them globally is probably wrong anyway (what if you called another function that had a loop like the one in sum!).

64-bit Compatibility
for example, consider this code: #define pointer_tagbits 3 static inline uintptr_t unmaskpointer(uintptr_t v) { return v & ~pointer_tagbits; } the value 3 will be inverted to 0xfffffffc, then zero-extended to 0x00000000fffffffc - a subtle and nasty bug, assuming it is unintended.
...the correct code is, assuming the index is unsigned: lir->insload(lir_ldp, lir->ins2(lir_piadd, arrayins, lir->ins_u2p(lir->ins2i(lir_mul, indexins, sizeof(int))) ), 0); what's pointer-width in tracerecorder?

Tracing JIT
some other terminology may be helpful when reading the code: the term guard denotes a condition that is checked by an executing trace to confirm that some assumptions made during recording still hold.
... if guard's condition fails to hold, the guard either jumps to an exit or, if the guard has been extended, jumps to a sub-trace that has been recorded under the opposite assumption as the guard was checking.

JSAPI Cookbook

Building the WebLock UI
in this tutorial, focusing as it is on the weblock functionality (rather than the ui), we'll assume the strings we get from the ui itself are urls we actually want to write to the white list: function addthissite() { var tf = document.getelementbyid("dialog.input"); // weblock is global and declared above weblock.addsite(tf.value); } this javascript function can be called directly from the xul widget, where the input string is retrieved as the value property of the textbox element.
...(note: we include three images to represent the state of the weblock, but wlock.gif and wl-lock.gif are identical, since weblock is presumed to be unlocked when it's loaded.

Creating the Component Code
the component manager is an interface implemented by xpcom that encapsulates the creation of objects and provides summary information about all registered components.
...given the example above, someone could create the sample object via the component manager as follows: nsicomponentmanager* compmanager; // assume initialized nsisupports* sample; compmanager->createinstance(ksamplecid, nsnull, kisupportsiid, (void**)&sample); in the above snippet, we assume that the component manager has been initialized.

Preface
however, this book does not assume any prior knowledge of com - all of the basic com ideas will be introduced.

How to build a binary XPCOM component using Visual Studio
the tutorial assumes the folder is called xulrunner-1.8.0.4, but you can call yours whatever you want.

Components.Constructor
summary creates a javascript function which can be used to create or construct new instances of xpcom components.
...om base principles with instance creation using components.constructor(); the latter is much easier to read than the former (particularly if you're creating instances of a component in many different places): var bis = components.classes["@mozilla.org/binaryinputstream;1"] .createinstance(components.interfaces.nsibinaryinputstream); bis.setinputstream(someinputstream); // assumes binaryinputstream was initialized previously var bis = new binaryinputstream(someinputstream); components.constructor() is purely syntactic sugar (albeit speedy and pretty syntactic sugar) for actions that can be accomplished using other common methods.

Components.utils.exportFunction
allowcrossoriginarguments: do not check that arguments to the exported function are subsumed by the caller: this allows the caller to pass objects with a different origin into the exported function, which can then use its privileged status to make cross-origin requests with them.
... unsafewindow, { defineas: "loguser" }); // less-privileged scope: for example, a page script function getuser() { return "bill"; } var test = document.getelementbyid("test"); test.addeventlistener("click", function() { window.loguser(getuser); }, false); cross-origin checking when the exported function is called each argument, including this, is checked to make sure that the caller subsumes that argument.
