Extended. It's written primarily for developers working on the feature.\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003e\u003ch2\u003e\u003ca name\u003d\"TOC-Instant-URL\" /\u003e\r\nInstant URL\u003c/h2\u003e\r\nAn \u003ci\u003eInstant URL\u003c/i\u003e is a URL that matches the instant_url template of the default search engine. So, given the default Chrome installation, \"http://www.google.com/webhp\" and \"http://www.google.com/webhp?foo\u003dbar#q\u003dquux\" are considered Instant URLs, whereas \"http://www.google.com/accounts\" is not.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nInstant Extended allows Instant URLs to match more template fields of the default search engine, with restrictions. So, in the extended mode, \"https://www.google.com/?espv\u003d1\" and \"https://www.google.com/search?espv\u003d1\u0026amp;q\u003dfoo\" are also Instant URLs, whereas the corresponding URLs without the \"espv\u003d1\" parameter are not.\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003cb\u003e\r\nWhy does this matter?\u003cbr /\u003e\u003c/b\u003e\r\n\u003cbr /\u003e\r\nThe Chrome Instant functionality only works with Instant URLs. So, in extended mode, we extract query terms from a URL into the omnibox only if the URL is an Instant URL. Similarly, we create an InstantTab (described below) only if the URL is an Instant URL.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nIn addition, we try to bucket all Instant URLs (and only Instant URLs) into a dedicated renderer process (the \u003ci\u003eInstant renderer\u003c/i\u003e). I say \u003ci\u003etry to\u003c/i\u003e because we won't always succeed, as you'll see below. We also install the SearchBox extension only in the Instant renderer (and not other renderers). The SearchBox extension is responsible for implementing Chrome's side of the \u003ca href\u003d\"https://sites.google.com/a/chromium.org/dev/searchbox\"\u003eSearchBox API\u003c/a\u003e, so this means that only webpages loaded in the Instant renderer can access the API.\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003e\u003cb\u003eTerminology note:\u003c/b\u003e URLs can be classified into Instant URLs or non-Instant URLs. Webpages support Instant or they don't. In other words, to talk about Instant support, you need an actual page (WebContents). Throughout this document, we use the terms URL and page consistently in this manner. Of course pages have URLs, so we also say that \"a page has an Instant URL\" or \"a non-Instant URL page\".\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003e\u003ch2\u003e\u003ca name\u003d\"TOC-Determining-Instant-Support\" /\u003e\r\nDetermining Instant Support\u003c/h2\u003e\u003c/div\u003e\u003cdiv\u003e\u003cb\u003eWhat is Instant support?\u003cbr /\u003e\u003c/b\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003eWe want to know whether the page that we've loaded in the hidden Instant overlay actually supports Instant, i.e., the SearchBox API. We start by loading the default search engine's Instant URL into the overlay, but after it goes through redirects, it may end up in a page that may or may not support Instant.\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003cb\u003e\r\nWhy do we want to determine Instant support?\u003cbr /\u003e\u003c/b\u003e\r\n\u003cbr /\u003e\r\nSay the page isn't known to support Instant yet. When the user types in the omnibox, we should immediately fallback to the local omnibox popup. Doing otherwise is bad. If the user types, and we send \u003ccode\u003eonchange()\u003c/code\u003e to the page, hoping that it will eventually respond, we would be making the user wait. Conversely, if we know that the page supports Instant, we can and should send onchange() to it, instead of falling back to the local omnibox popup, since the local popup is an inferior experience.\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003cb\u003e\r\nHow do we determine Instant support?\u003cbr /\u003e\u003c/b\u003e\r\n\u003cbr /\u003e\r\nWe start by assuming the page doesn't support Instant. At some point, the browser sends an IPC to the renderer. The SearchBox receives it, checks if \u003ccode\u003ewindow.chrome.searchBox.onsubmit()\u003c/code\u003e is a JS function defined in the page, and responds. When the response IPC is received by the browser, it thus determines Instant support.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nAlso, if the browser receives an IPC at any point that's part of the SearchBox API (such as \u003ci\u003eSetSuggestions\u003c/i\u003e or \u003ci\u003eShowInstantPreview\u003c/i\u003e), it considers the page to support Instant.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nOnly pages that are Instant URLs can support Instant. A random non-Instant URL webpage can define the onsubmit() method, but there'll be no SearchBox extension available to receive or send the appropriate IPCs. In other words, a random webpage can't fool the browser into thinking it supports Instant (however, see the caveat in footnote [1]).\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003cb\u003e\r\nWhen do we determine Instant support?\u003cbr /\u003e\u003c/b\u003e\r\n\u003cbr /\u003e\r\nThe browser waits for the page to fully load and then sends the IPC mentioned above. This happens in the Instant implementation of \u003ccode\u003eWebContentsObserver::DidFinishLoad()\u003c/code\u003e.\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003cb\u003e\r\nWhy don't we just check to see if the final page loaded in the Instant renderer?\u003cbr /\u003e\u003c/b\u003e\r\n\u003cbr /\u003e\r\nFirst, even if the page is an Instant URL, it might not actually support Instant. For example, \"http://www.google.com/webhp\" might be a recognized Instant URL (so it gets assigned to the Instant renderer), but when it loads, the page may disable Instant due to server side experiments or other failures.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nSecond, the page may go through one or more redirects that cause a \u003ci\u003ecross-process navigation\u003c/i\u003e (see the OpenURLFromTab section below). If one of these redirects is renderer-initiated (e.g.: using \u003ccode\u003elocation.href \u003d \"...\"\u003c/code\u003e or a \u003ccode\u003e\u0026lt;meta http-equiv\u003drefresh\u0026gt;\u003c/code\u003e tag), we'll still get a DidFinishLoad(). Say \"http://www.google.com/webhp\" (the Instant URL we initially load) uses a JS redirect to \"http://www.google.com/accounts\" (a non-Instant URL), which, after verifying your login cookies, redirects you back to the \"/webhp\" URL, again through a JS redirect. At some point, we'll get a DidFinishLoad() for the \"/accounts\" URL. If we check the renderer at that time, we will wrongly conclude that the page doesn't support Instant.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nIn fact, we do actually send the request IPC after \"/accounts\" loads (because of DidFinishLoad(), as mentioned above). But by the time the response IPC comes back, the browser already knows about the JS redirect and is in the midst of handling it, so it knows that the response is for an older page, and ignores it. This is achieved by checking \u003ccode\u003eWebContents::IsActiveEntry()\u003c/code\u003e using the page_id contained in the response IPC.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nOf course, it's possible for the JS redirect to happen much later through a delayed timer, in which case, the \"/accounts\" URL is still the active entry when the browser receives the response IPC. In this case, we'll conclude that the page doesn't support Instant. This is okay since we can't possibly handle arbitrarily delayed redirects. Our method works for the common case of an immediate JS redirect.\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003cb\u003e\r\nWhat happens if the final page isn't an Instant URL? We will never get a response IPC, right?\u003cbr /\u003e\u003c/b\u003e\r\n\u003cbr /\u003e\r\nTrue, since there's no SearchBox extension in that page's renderer. However, in the absence of a response IPC, the browser will continue to treat the page as not supporting Instant, so it all works out.\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003e\u003ch2\u003e\u003ca name\u003d\"TOC-OpenURLFromTab\" /\u003e\r\nOpenURLFromTab\u003c/h2\u003e\r\n\u003ccode\u003eWebContentsDelegate::OpenURLFromTab()\u003c/code\u003e is called whenever there's a cross-process navigation. This can happen in a few different ways:\u003cbr /\u003e\r\n\u003cbr /\u003e\u003cb\u003e\r\nCase 1:\u003c/b\u003e The initial page load of the Instant URL in the hidden overlay may go through a series of HTTP redirects, any of which may trip the cross-process bit. Say we start by loading URL A. It redirects to URL B, which is \"claimed\" by an installed app (i.e., the app has listed B in its list of URL patterns in its manifest.json). Apps are loaded in separate renderer processes, so the redirect from A to B causes a cross-process navigation. HTTP redirects that are not claimed by any app do \u003cb\u003enot\u003c/b\u003e trip the cross-process bit, even if they are not Instant URLs. I.e., if URL A is an Instant URL, but URL B is not, B will still be loaded in the same Instant renderer process that we started out with. [1]\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nAlternatively, we'll hit the cross-process case if any of the redirects are renderer-initiated (as mentioned in the previous section, using location.href or a \u0026lt;meta\u0026gt; tag). Normally, renderer-initiated navigations (including redirects) are considered cross-process only if they actually cross an app or extension boundary (see \u003ccode\u003eRenderViewImpl::decidePolicyForNavigation()\u003c/code\u003e). For Instant however, we have added some code that makes \u003cb\u003eall\u003c/b\u003e renderer-initiated navigations be initially treated as cross-process (see \u003ccode\u003eChromeContentRendererClient::ShouldFork()\u003c/code\u003e).\u003cbr /\u003e\r\n\u003cbr /\u003e\u003cb\u003e\r\nCase 2:\u003c/b\u003e Say we are showing the Instant overlay (URL A), and the user does something (such as click on a link) that causes the page to navigate to URL B, tripping a renderer-initiated cross-process navigation (as explained above). Assume that the click by itself doesn't cause the overlay to be committed (because the overlay is showing at less than full height).\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nLet's look at what happens if B is not considered to be an Instant URL (in both cases above). In Case 2, we want to commit the overlay if possible, since it would be a mistake to try to continue using the overlay (B cannot support the Instant API, so the overlay would just stop working). However, in Case 1, we don't want to commit or discard the overlay just yet, since it's part of the initial series of redirects, and the final Instant page hasn't even been loaded yet.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nThe way we distinguish these cases is by looking at whether the overlay is already known to support Instant.

But in that case, the overlay shouldn't be showing any links other than suggestions (in particular, there should be no search results, search tools, Google+ widgets or such). If the user clicks on a suggestion, the page will request for it through the SearchBox API (\u003ci\u003enavigateContentWindow\u003c/i\u003e for URLs and \u003ci\u003eshow(reason\u003dquery)\u003c/i\u003e for queries), so the page shouldn't cause an OpenURLFromTab() call. If something slips through the cracks (say because the overlay showed a \"Learn more\" link that the user clicked), we'll just disallow the navigation, which means the overlay remains showing the Instant page, and continues to work.\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003ch2\u003e\u003ca name\u003d\"TOC-InstantTab\" /\u003e\r\nInstantTab\u003c/h2\u003e\r\nIn Instant Extended mode, an \u003ci\u003eInstantTab\u003c/i\u003e represents a committed page (i.e., an actual tab on the tabstrip, and not an overlay) that's an Instant URL. Typically, this is either the server-provided NTP (New Tab Page) or a search results page. Such a page can also be used to show Instant suggestions and results, so it's appropriate to ask whether an InstantTab supports the Instant API.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nAn InstantTab is a lightweight wrapper that's deleted and recreated as the user switches tabs (i.e., Instant only has a single InstantTab object, not one per tab). When the user switches to a tab with an Instant URL, we create an InstantTab wrapper around it, starting as usual by assuming that it doesn't support Instant. We then immediately send the request IPC. The rest of the Instant support determination works similar to the overlay. Since we (Instant) are not the WebContentsDelegate for a committed tab, none of the OpenURLFromTab() issues arise here. Note that we reset the InstantTab when the user switches tabs. We don't store the result of the Instant support determination anywhere permanently in the tab's WebContents.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nThis generally works well, except for the following case: If the tab is a server-provided NTP (\"http://www.google.com/webhp\"), it's possible that we just created the WebContents and had to immediately commit it, so the page hasn't fully loaded yet. Since the common case is to open a browser with the NTP, we don't want to fall back to the local NTP just because we haven't finished loading the server-provided NTP. But, if the user starts typing into the omnibox before the NTP finishes loading, we don't want to wait for the server page (since that could take an arbitrary amount of time). In such a case (user typing before the NTP finishes loading), we'll fallback to the overlay (local omnibox popup).\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003cb\u003e\r\nDoes that mean that we fallback to the overlay whenever the user types, but we haven't yet determined Instant support for an InstantTab?\u003cbr /\u003e\u003c/b\u003e\r\n\u003cbr /\u003e\r\nNo, that would mean practically every time the user switches to a tab and immediately starts typing, we'll end up with the overlay.

For example, an Instant URL tab might have been created without Instant (i.e., through a link click or a bookmark navigation). When the user switches to it the first time, we still have to perform Instant support determination. Also, storing this bit with the WebContents means storing it somewhere within the SearchTabHelper, and this introduces unnecessary complexity (what should happen to that bit if the tab navigates in the background?) and leaks Instant concepts to an unrelated part of the codebase.\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003cb\u003e\r\nWhat's the solution then?\u003cbr /\u003e\u003c/b\u003e\r\n\u003cbr /\u003eIf we are on an InstantTab, and we haven't yet determined its Instant support, switch to the overlay only if the page hasn't finished loading. The reason this works is that, if the page has finished loading , we can go ahead and blindly send the onchange() to it as the user types. Note that we are not waiting for the page to load to determine Instant support. We send the IPC as soon as the user switches to the tab. Waiting for a page to load is the long pole that takes an indeterminate amount of time. Waiting for an IPC is a much smaller, mostly determinate amount of time (a few milliseconds, usually). So, if it turns out that the page doesn't support Instant, we'll quickly discover that and fallback to the overlay anyway.\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003e\u003cb\u003eWhat happens if the tab is a \"sad tab\", i.e., the page has crashed?\u003c/b\u003e\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003eRight.

Recall that a renderer-initiated navigation normally isn't cross-process unless it crosses an app boundary.

Now, this tab is eligible to be treated as an InstantTab. But the page is still in the non-Instant renderer, so we'll never get the response IPC back.

However, with template code, you are playing with the type system.  In particular with callbacks, it's possibly to accidentally write code that allows unsafe type conversion leading to a code execution.  Here's a specific example:\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003e   int func(double f) {\u003c/div\u003e\u003cdiv\u003e      printf(\"woohoo!

arguments func originally needed, or what types they were.  Somewhere between the call to Bind() and the assignment, the type of func:int(int), and the type of 1:int was captured and erased so that it could be assigned into a Callback that only knew the resulting function was int(void).  To do this, there is some casting happening that can break type safety.  In the Bind() implementation, the code has been constructed carefully to fail at compile time if you were to try and do something like:\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003e

can occur.  In fact, they already snuck in once.  To ensure we do not regress in behavior and allow a dangerous type safety violation, we need a set of \"no compile tests\" that assert that known dangerous constructs will not silently compile.  This makes it much safer to modify the Bind() implementation.\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003eThough this

Autotest is responsible for managing the state of multiple client devices as a distributed system, by integrating a web interface, database, servers and the clients themselves. Since this codelab is about client tests, what follows is a short description of how autotest runs a specific test, on one client. \u003c/span\u003e\u003c/p\u003e\u003cp style\u003d\"line-height:1.15;margin-top:0pt;margin-bottom:0pt\"\u003e\u003cspan style\u003d\"background-color:transparent;font-family:Arial;font-size:15px;white-space:pre-wrap;line-height:1.15\"\u003e\u003cbr /\u003e\u003c/span\u003e\u003c/p\u003e\u003cp style\u003d\"line-height:1.15;margin-top:0pt;margin-bottom:0pt\"\u003e\u003cspan style\u003d\"background-color:transparent;font-family:Arial;font-size:15px;white-space:pre-wrap;line-height:1.15\"\u003eAutotest looks through all directories in client/tests and client/site_tests for simple python files that begin with ‘control.’. These files contain a list of variables, and a call to job.run_test. The control variables tell autotest when to schedule the test, and the call to run_test tells autotest how. Each test instance is part of a job. Autotest creates this job object and forks a child process to execute its control file.\u003c/span\u003e\u003c/p\u003e\u003c/span\u003e\u003cspan\u003e\u003cp dir\u003d\"ltr\" style\u003d\"line-height:1.15;margin-top:0pt;margin-bottom:0pt\"\u003e\u003cimg height\u003d\"107px;\" src\u003d\"https://docs.google.com/a/google.com/drawings/d/szgUiW_L7jkUJospRoV-dlQ/image?w\u003d668\u0026amp;h\u003d107\u0026amp;rev\u003d1\u0026amp;ac\u003d1\" width\u003d\"668px;\" /\u003e\u003c/p\u003e\u003cp dir\u003d\"ltr\" style\u003d\"line-height:1.15;margin-top:0pt;margin-bottom:0pt\"\u003e\u003cspan style\u003d\"font-size:11px;font-family:Arial;background-color:transparent;vertical-align:baseline;white-space:pre-wrap\"\u003eNote the exec mentioned above is the python keyword, not os.exec\u003c/span\u003e\u003c/p\u003e\u003cbr /\u003e\u003cp dir\u003d\"ltr\" style\u003d\"line-height:1.15;margin-top:0pt;margin-bottom:0pt\"\u003e\u003cspan style\u003d\"font-size:15px;font-family:Arial;background-color:transparent;vertical-align:baseline;white-space:pre-wrap\"\u003eTests reside in a couple of key locations in your checkout, and map to similar locations on the DUT (Device Under Test).

They support compelling web applications that can run offline or with intermittent connectivity. You can edit documents, browse and buy from catalogs, send social media messages, write email, etc. even in the subway! Service Workers can make the web platform more viable than ever before, enabling web apps to better compete with native apps even while essentially retaining the browse-to-use, sandboxed nature of the \u003c/span\u003e\u003ca href\u003d\"https://www.w3.org/wiki/Open_Web_Platform\" rel\u003d\"nofollow\"\u003e\u003cspan style\u003d\"color:rgb(17,85,204);background-color:transparent;vertical-align:baseline;white-space:pre-wrap\"\u003eOpen Web Platform\u003c/span\u003e\u003c/a\u003e\u003cspan style\u003d\"background-color:transparent;vertical-align:baseline;white-space:pre-wrap\"\u003e (OWP) that we all love.

This makes it immediately obvious if you are changing one of the assets that the other density assets may need to be changed as well.

In particular, if it can determine from a given CSS image rule such as content: url('../my/image/foo.png') that a 2x image is available, then it will automatically generate an image set referring to both the 1x and 2x image. This is accomplished by using a '2x' (or scale factor + 'x') subdirectory where the 1x image is located. This allows images to be located in each of the relevant component directories and can deal with any relative image path appropriately. Since native resources must be centrally located a different tradeoff was made with respect to directory structure so we have to manually reference each density asset in folders outside of \u003ci\u003echrome/browser/resources/\u003c/i\u003e.\u003c/font\u003e\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003e\u003cfont face\u003d\"arial, sans-serif\"\u003eTheme resources are loaded by name, and in practice can be changed dynamically. In order to fetch various density theme resources theme_source.cc was modified to accept theme source requests such as chrome://theme/IDR_RESOURCE_NAME@2x and fetch the appropriate theme image. If a high DPI theme resource is not available it falls back to returning the 1x theme resource which means that in any place where you use a theme source which may not have a 2x asset it should have the size of the image explicitly set. Otherwise, the 1x image is returned, assumed to be 2x and scaled down to half the size such that it is displayed 1:1 on a 2x screen.\u003c/font\u003e\u003c/div\u003e\u003c/div\u003e\u003c/td\u003e\u003c/tr\u003e\u003c/tbody\u003e\u003c/table\u003e\u003c/div\u003e"},"link":[{"rel":"http://schemas.google.com/sites/2008#parent","type":"application/atom+xml","href":"https://sites.google.com/feeds/content/chromium.org/dev/3863791766242792620"},{"rel":"alternate","type":"text/html","href":"https://sites.google.com/a/chromium.org/dev/developers/design-documents/high-dpi-resources"},{"rel":"http://schemas.google.com/sites/2008#revision","type":"application/atom+xml","href":"https://sites.google.com/feeds/revision/chromium.org/dev/2514578343425486059"},{"rel":"self","type":"application/atom+xml","href":"https://sites.google.com/feeds/content/chromium.org/dev/2514578343425486059"},{"rel":"edit","type":"application/atom+xml","href":"https://sites.google.com/feeds/content/chromium.org/dev/2514578343425486059"}],"author":[{"name":{"$t":"Robert Flack"},"email":{"$t":"flackr@chromium.org"}}],"sites$pageName":{"$t":"high-dpi-resources"},"sites$revision":{"$t":"11"}},{"gd$etag":"\"YD4peyY.\"","id":{"$t":"https://sites.google.com/feeds/content/chromium.org/dev/4183282741093229527"},"published":{"$t":"2017-07-07T19:35:50.791Z"},"updated":{"$t":"2017-07-17T21:26:39.989Z"},"app$edited":{"xmlns$app":"http://www.w3.org/2007/app","$t":"2017-07-17T21:26:39.975Z"},"category":[{"scheme":"http://schemas.google.com/g/2005#kind","term":"http://schemas.google.com/sites/2008#attachment","label":"attachment"}],"title":{"$t":"Flash Volume - Update July 6.png"},"summary":{},"content":{"type":"image/png","src":"https://a77db9aa-a-7b23c8ea-s-sites.googlegroups.com/feeds/media/content/chromium.org/dev/4183282741093229527"},"link":[{"rel":"http://schemas.google.com/sites/2008#parent","type":"application/atom+xml","href":"https://sites.google.com/feeds/content/chromium.org/dev/983518581610832010"},{"rel":"alternate","type":"image/png","href":"https://sites.google.com/a/chromium.org/dev/flash-roadmap/flash-usage-trends/Flash%20Volume%20-%20Update%20July%206.png"},{"rel":"http://schemas.google.com/sites/2008#revision","type":"application/atom+xml","href":"https://sites.google.com/feeds/revision/chromium.org/dev/4183282741093229527"},{"rel":"self","type":"application/atom+xml","href":"https://sites.google.com/feeds/content/chromium.org/dev/4183282741093229527"},{"rel":"edit","type":"application/atom+xml","href":"https://sites.google.com/feeds/content/chromium.org/dev/4183282741093229527"},{"rel":"edit-media","type":"image/png","href":"https://sites.google.com/feeds/media/content/chromium.org/dev/4183282741093229527"}],"author":[{"name":{"$t":"Anthony LaForge"},"email":{"$t":"laforge@chromium.org"}}],"sites$revision":{"$t":"2"}},{"gd$etag":"\"YDgpeyY.\"","id":{"$t":"https://sites.google.com/feeds/content/chromium.org/dev/7013358383000086029"},"published":{"$t":"2016-08-24T21:23:30.774Z"},"updated":{"$t":"2017-07-14T07:02:46.380Z"},"app$edited":{"xmlns$app":"http://www.w3.org/2007/app","$t":"2017-07-14T07:02:43.785Z"},"category":[{"scheme":"http://schemas.google.com/g/2005#kind","term":"http://schemas.google.com/sites/2008#webpage","label":"webpage"}],"title":{"$t":"View Test Result via WMatrix"},"content":{"type":"xhtml","$t":"\u003cdiv xmlns\u003d\"http://www.w3.org/1999/xhtml\"\u003e\u003ctable cellspacing\u003d\"0\" class\u003d\"sites-layout-name-one-column sites-layout-hbox\"\u003e\u003ctbody\u003e\u003ctr\u003e\u003ctd class\u003d\"sites-layout-tile sites-tile-name-content-1\"\u003e\u003cdiv dir\u003d\"ltr\"\u003e\u003cdiv\u003e\u003cspan style\u003d\"color:rgb(255,0,0);font-size:x-large;font-weight:bold\"\u003e***DEPRECATED, PLEASE VISIT https://sites.google.com/a/chromium.org/dev/chromium-os/testing/moblab *** (20170714)\u003c/span\u003e\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003eStarting with M52, Moblab AFE UI will have a link to WMatrix, which will present a better test result viewing UI for Moblab users.\u003cdiv\u003e\u003cdiv style\u003d\"display:block;text-align:left\"\u003e\u003ca href\u003d\"https://sites.google.com/a/chromium.org/dev/chromium-os/testing/moblab/view-test-result-vis-wmatrix/Selection_980.png?attredirects\u003d0\" imageanchor\u003d\"1\"\u003e\u003cimg border\u003d\"0\" src\u003d\"https://sites.google.com/a/chromium.org/dev/_/rsrc/1472074050570/chromium-os/testing/moblab/view-test-result-vis-wmatrix/Selection_980.png\" /\u003e\u003c/a\u003e\u003c/div\u003e\u003cdiv style\u003d\"display:block;text-align:left\"\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv style\u003d\"display:block;text-align:left\"\u003eThe Test Results UI might look a little overwhelming.

Treating gesture events in the same manner as mouse events when determining the event's target can lead to a poor experience for touchscreen users because a touch region can overlap many more possible targets than a mouse cursor and it is difficult to ensure that the center of the touch region is over the intended target (especially if that target is small, such as the tab close button). \u003c/span\u003e\u003c/span\u003e\u003cspan style\u003d\"font-family:Arial;line-height:17px;white-space:pre-wrap;background-color:transparent\"\u003eThe goal of this feature is to add support for rect-based event targeting (\"fuzzing\") by using a heuristic to determine the most probable target of a gesture having its touch region represented by a rectangle.\u003c/span\u003e\u003c/font\u003e\u003c/div\u003e\u003cdiv\u003e\u003cspan\u003e\u003cspan style\u003d\"font-family:Arial;background-color:transparent;vertical-align:baseline;white-space:pre-wrap\"\u003e\u003cfont size\u003d\"2\"\u003e\u003cbr /\u003e\u003c/font\u003e\u003c/span\u003e\u003c/span\u003e\u003c/div\u003e\u003cdiv\u003e\u003cspan\u003e\u003cspan style\u003d\"font-size:15px;font-family:Arial;background-color:transparent;vertical-align:baseline;white-space:pre-wrap\"\u003e\u003cbr /\u003e\u003c/span\u003e\u003c/span\u003e\u003c/div\u003e\u003cdiv\u003e\u003cspan\u003e\u003cspan style\u003d\"font-family:Arial;background-color:transparent;vertical-align:baseline;white-space:pre-wrap\"\u003e\u003cfont size\u003d\"4\"\u003e\u003cb\u003eSolution\u003c/b\u003e\u003c/font\u003e\u003c/span\u003e\u003c/span\u003e\u003c/div\u003e\u003cdiv\u003e\u003cspan\u003e\u003cspan style\u003d\"font-family:Arial;background-color:transparent;vertical-align:baseline;white-space:pre-wrap\"\u003e\u003cfont size\u003d\"2\"\u003e\u003cbr /\u003e\u003c/font\u003e\u003c/span\u003e\u003c/span\u003e\u003c/div\u003e\u003cdiv\u003e\u003cspan\u003e\u003cfont size\u003d\"2\"\u003e\u003cp dir\u003d\"ltr\" style\u003d\"line-height:1.15;margin-top:0pt;margin-bottom:0pt\"\u003e\u003cspan style\u003d\"font-family:Arial;background-color:transparent;vertical-align:baseline;white-space:pre-wrap\"\u003eThis heuristic is implemented in \u003c/span\u003e\u003cspan style\u003d\"background-color:transparent;vertical-align:baseline;white-space:pre-wrap\"\u003e\u003cfont face\u003d\"courier new, monospace\"\u003e\u003cb\u003eView::GetEventHandlerForRect()\u003c/b\u003e\u003c/font\u003e\u003cfont face\u003d\"arial, sans-serif\"\u003e with the \u003c/font\u003e\u003c/span\u003e\u003cspan style\u003d\"font-family:Arial;line-height:17px;white-space:pre-wrap;background-color:transparent\"\u003eidea that small targets are more difficult to touch reliably than large targets, so small targets should get priority when determining the most probable target of a gesture.\u003c/span\u003e\u003cspan style\u003d\"background-color:transparent;font-family:Arial;vertical-align:baseline;white-space:pre-wrap\"\u003e The heuristic works by recursively looking for candidate targets among the descendants of \u003c/span\u003e\u003cspan style\u003d\"background-color:transparent;vertical-align:baseline;white-space:pre-wrap\"\u003e\u003cfont face\u003d\"courier new, monospace\"\u003e\u003cb\u003ethis\u003c/b\u003e\u003c/font\u003e\u003c/span\u003e\u003cspan style\u003d\"background-color:transparent;font-family:Arial;vertical-align:baseline;white-space:pre-wrap\"\u003e which the touch region overlaps by at least 60%.

The reason for this change is that the current security model of the Credential Management API is not as effective as desired (see e.g. \u003ca href\u003d\"https://github.com/w3c/webappsec-credential-management/issues/58\" rel\u003d\"nofollow\"\u003ehere\u003c/a\u003e) and the current fetch based infrastructure has reported usability issues (e.g. it's impossible to send JSON or apply a hash to the password before sending).

This will be accomplished by a combination of local heuristics and integration with Autofill. In particular, the password manager will upload information to Autofill servers when a user signs in using a saved password on a form different from the one it was saved on. This gives a strong signal that the original form was used for account creation. This data is then aggregated to determine if the form is or isn't used for account creation. Those that are will be labeled as such by Autofill. If a signal is received from Autofill when the form is rendered, we mark the password field. When the users focuses this field, we show an Autofill like dropdown with a password suggestion.\u003c/font\u003e\u003c/div\u003e\u003cdiv\u003e\u003cfont size\u003d\"2\"\u003e\u003cbr /\u003e\u003c/font\u003e\u003c/div\u003e\u003cdiv\u003e\u003cfont size\u003d\"2\"\u003e\u003cdiv style\u003d\"display:block;text-align:left\"\u003e\u003ca href\u003d\"https://sites.google.com/a/chromium.org/dev/developers/design-documents/password-generation/GenerationUI.png?attredirects\u003d0\" imageanchor\u003d\"1\"\u003e\u003cimg border\u003d\"0\" src\u003d\"https://sites.google.com/a/chromium.org/dev/_/rsrc/1394745053088/developers/design-documents/password-generation/GenerationUI.png\" /\u003e\u003c/a\u003e\u003c/div\u003e\u003c/font\u003e\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003e\u003cfont size\u003d\"2\"\u003e\u003cbr /\u003e\u003c/font\u003e\u003c/div\u003e\u003cdiv\u003e\u003cfont size\u003d\"2\"\u003eThe generated password is generic enough that it works on most sites as is, but not all sites have the same requirements.

to see this caused by a slow task on the Chrome_IOThread (i.e., the thread used for IPC communications with the renderer).  At times, some threads send messages to other threads to get work results, and may be waiting (without officially \"blocking\") for a posted response, so almost any blocked thread *might* be able to cause jank, but the Chrome_FileThread (i.e., the thread that reads and

Masonry's layout_avg is usually around 70ms, and the stddev in its layout_avg between runs is about 1-2ms, which is about 3% variation.

Currently this number stands at about 10x, depending on what font and what font_funcs implementation.  More measurement and optimizations here are possible.\u003c/p\u003e\r\n\r\n\u003ch3\u003e\u003ca name\u003d\"TOC-Benchmarks\" /\u003eBenchmarks\u003c/h3\u003e\r\n\u003cp\u003eWe should restructure our telemetry benchmarks specifically for text measurement performance, perhaps have a separate group of tests besides blink_perf.Layout.\u003c/p\u003e\r\n\u003cp\u003eIn addition to that, we need to develop new test cases, to better cover real world text-performance heavy use cases.\u003c/p\u003e\r\n\r\n\u003cp\u003eOut of that effort we could develop a publicly available text layout benchmark, to compare Blink performance against other engines.

This will give us an extra performance win as it allows all text path branching to be removed, including costly string scans. It would also allow us to enable typesetting features, such as kerning and ligatures, for all text. More importantly though it would allow us to have a single unified text layout path which in turn would reduce complexity and maintenance costs as well as as ensure consistent performance regardless of script.\u003c/p\u003e\r\n\r\n\r\n\u003c/div\u003e\u003c/div\u003e\u003c/td\u003e\u003c/tr\u003e\u003c/tbody\u003e\u003c/table\u003e\u003c/div\u003e"},"link":[{"rel":"http://schemas.google.com/sites/2008#parent","type":"application/atom+xml","href":"https://sites.google.com/feeds/content/chromium.org/dev/3250862627189304315"},{"rel":"alternate","type":"text/html","href":"https://sites.google.com/a/chromium.org/dev/teams/layout-team/eliminating-simple-text"},{"rel":"http://schemas.google.com/sites/2008#revision","type":"application/atom+xml","href":"https://sites.google.com/feeds/revision/chromium.org/dev/9146647775906495762"},{"rel":"self","type":"application/atom+xml","href":"https://sites.google.com/feeds/content/chromium.org/dev/9146647775906495762"},{"rel":"edit","type":"application/atom+xml","href":"https://sites.google.com/feeds/content/chromium.org/dev/9146647775906495762"}],"author":[{"email":{"$t":"eae@chromium.org"}}],"sites$pageName":{"$t":"eliminating-simple-text"},"sites$revision":{"$t":"5"}},{"gd$etag":"\"YD0peyY.\"","id":{"$t":"https://sites.google.com/feeds/content/chromium.org/dev/7832983298878609177"},"published":{"$t":"2017-04-18T02:13:14.155Z"},"updated":{"$t":"2017-04-18T02:13:14.189Z"},"app$edited":{"xmlns$app":"http://www.w3.org/2007/app","$t":"2017-04-18T02:13:14.155Z"},"category":[{"scheme":"http://schemas.google.com/g/2005#kind","term":"http://schemas.google.com/sites/2008#attachment","label":"attachment"}],"title":{"$t":"PPS Tiny -

is, the  UI needs to be localized for each language such that any UI text element (menus, titles, labels, etc.) is displayed in the target language. In order to make sure that Chromium can be easily localized to different languages (an effort known as \u003ci\u003elocalizability\u003c/i\u003e), the Chromium source code is structured such that localizable strings are stored in locale-specific DLLs. This way, the actual UI strings are loaded from the right DLL, depending on the target locale. There is one more localizability aspect which applies only to right-to-left (RTL) languages, such as Hebrew and Arabic. In such languages, translating the strings to the target language is not enough. In order to provide a perfect right-to-left look and feel to the browser, the entire UI needs to be mirrored.\u003c/p\u003e\r\n\u003cp\u003eThis document starts by providing a brief overview of the UI mirroring technology in general and in particular the Windows support for UI mirroring. Then, the newly added ChromeViews mirroring infrastructure is described. Using this new infrastructure, the Chromium UI elements can be easily mirrored for RTL locales. Finally, and most importantly, the document provides a set of guidelines for writing Chromium UI elements that don't break when mirrored in RTL UIs.\u003c/p\u003e\r\n\u003ch2\u003e\u003ca name\u003d\"TOC-Windows-UI-mirroring-architecture\" /\u003eWindows UI mirroring architecture \u003c/h2\u003e\r\n\u003ch3\u003e\u003ca name\u003d\"TOC-An-example\" /\u003eAn example \u003c/h3\u003e\r\n\u003cp\u003eThe Windows operating system itself has been localized for a large set of languages, including right-to-left languages like Hebrew. Thus, users of the Hebrew version of Windows are presented with a mirrored version of the English OS UI. Before we examine the mirroring Windows API available to application developers, it will be helpful to compare the mirrored and the non-mirrored versions of a fundamental Windows UI component - Windows Explorer. Looking at the manner in which the Windows OS mirrors its core UI elements will shed some light on the ChromeViews Mirroring Infrastructure design. The following diagram shows the English version of Windows Explorer we are all familiar with:\u003c/p\u003e\r\n\u003cdiv style\u003d\"display:block;text-align:left\"\u003e\u003ca href\u003d\"https://sites.google.com/a/chromium.org/dev/developers/design-documents/ui-mirroring-infrastructure/explorer_window_en_us.jpg?attredirects\u003d0\" imageanchor\u003d\"1\"\u003e\u003cimg border\u003d\"0\" src\u003d\"https://sites.google.com/a/chromium.org/dev/_/rsrc/1220197834541/developers/design-documents/ui-mirroring-infrastructure/explorer_window_en_us.jpg\" /\u003e\u003c/a\u003e\u003c/div\u003e\r\n\u003cp\u003eThe first thing to note about the English version is that left alignment is used for all the text elements. Also, there are two groups of highlighted UI elements (the red group and the black group) that behave differently when displayed in a mirrored UI. The elements in both groups contain an image (a bitmap or an icon). All the elements in the red group (elements 1, 2 and 3) contain direction sensitive images; that is, the images in these elements must be flipped horizontally when displayed in mirrored UIs. Not flipping direction sensitive graphics can cause various UI problems. For example, not flipping the resize bitmap (item 3) will cause the UI to appear incorrectly - a Southeast-oriented resize bar will appear in the Southwest corner of the window. Not flipping the back button (item 1) will result in a confusing user experience - the button will say 'Back' but the arrow will point to a direction indicating going 'Forward'. All the elements in the black group (elements A, B and C) do not contain direction sensitive images. Thus, the images in these elements must look the same in mirrored and non-mirrored UIs. Generally, legal trademarks, logos, favicons, etc. are not direction sensitive and flipping them horizontally in mirrored UIs does not make sense. Following is the Hebrew (and therefore mirrored) version of Windows Explorer:\u003c/p\u003e\r\n\u003cdiv style\u003d\"display:block;text-align:left\"\u003e\u003ca href\u003d\"https://sites.google.com/a/chromium.org/dev/developers/design-documents/ui-mirroring-infrastructure/explorer_window_he.jpg?attredirects\u003d0\" imageanchor\u003d\"1\"\u003e\u003cimg border\u003d\"0\" src\u003d\"https://sites.google.com/a/chromium.org/dev/_/rsrc/1220197834922/developers/design-documents/ui-mirroring-infrastructure/explorer_window_he.jpg\" /\u003e\u003c/a\u003e\u003c/div\u003e\r\n\u003cp\u003eThe first thing to note about the Hebrew version is that right alignment is used for all the text elements (English and Hebrew). Also, all the UI text (menus, buttons, status bar info, etc.) is translated to Hebrew. All the UI elements and sub-elements are mirrored recursively. For example, the position of the folder tree view is mirrored (it is on the right-hand side of the window and not the left-hand side). The elements in the tree view (the plus signs, the directory icons, etc.) also appear in their mirrored position within the tree view. Note how even though the position of all the highlighted elements is mirrored, the elements in the black group look exactly the same as they did in the English version while the elements in the red group are flipped horizontally.\u003c/p\u003e\r\n\u003ch3\u003e\u003ca name\u003d\"TOC-How-does-Windows-do-it-\" /\u003eHow does Windows do it? \u003c/h3\u003e\r\n\u003cp\u003eThe Windows API provides a set of useful techniques for dealing with RTL UI localization. The goal of the Windows UI mirroring API is to allow GUI developers to write UI code without having to worry about mirroring the UI for right-to-left locales. The UI is created using well known Windows GUI constructs (HWNDs, Device Contexts, Dialog Boxes, etc.) and then an RTL layout property can be applied to individual elements in order to mirror their UI. For example, the property WS_EX_LAYOUTRTL can be applied to an HWND in order to mirror the UI of the underlying window. When an RTL layout is applied to a GUI element, the element's coordinate system is transformed in the following manner:\u003c/p\u003e\r\n\u003cdiv style\u003d\"display:block;text-align:left\"\u003e\u003ca href\u003d\"https://sites.google.com/a/chromium.org/dev/developers/design-documents/ui-mirroring-infrastructure/ws_layout_rtl.jpg?attredirects\u003d0\" imageanchor\u003d\"1\"\u003e\u003cimg border\u003d\"0\" src\u003d\"https://sites.google.com/a/chromium.org/dev/_/rsrc/1220197836357/developers/design-documents/ui-mirroring-infrastructure/ws_layout_rtl.jpg\" /\u003e\u003c/a\u003e\u003c/div\u003e\r\n\u003cp\u003eWhen using an RTL layout, the right-most horizontal coordinate value is 0 (instead of the leftmost) and the coordinate values increase (instead of decrease) when moving from right to left on the X axis. Using this transformation, a UI element the application positions in the top left corner will be positioned on the top right corner when the UI is mirrored. The concept of coordinate transformation is extremely powerful since it doesn't require the GUI application's logic to change in order to support mirroring. In reality, however, more often than not mirroring a GUI application involves much more than just setting a few flags. There are a few bad programming practices that cause the GUI application to appear incorrectly when mirrored. For the most part these have to do with incorrect conversions between screen and window coordinates. To learn more about the Windows mirroring API and about how to avoid programming techniques that don't work well in mirrored UIs, see the following \u003ca href\u003d\"http://msdn2.microsoft.com/en-us/goglobal/bb688119.aspx\" rel\u003d\"nofollow\"\u003eMSDN article\u003c/a\u003e.\u003c/p\u003e\r\n\u003ch2\u003e\u003ca name\u003d\"TOC-ChromeViews-mirroring-infrastructure\" /\u003eChromeViews mirroring infrastructure \u003c/h2\u003e\r\n\u003cp\u003eChromium has a portable, object oriented UI framework (aka \u003ci\u003eChromeViews\u003c/i\u003e) that allows developers to write Chromium UI elements. In order to allow the Chromium UI to be mirrored easily, a mirroring infrastructure needed to be added to the \u003ci\u003eChromeViews\u003c/i\u003e framework. The inherent Windows support could not be used by itself to mirror the Chromium UI for a few different reasons:\u003c/p\u003e\r\n\u003cul\u003e\r\n\t\r\n\u003cli\u003eIn order to render the Chromium UI elements inside a Windows HWND (such as the window created by XPFrame), the entire Chromium UI is rendered into a DIB and then the DIB is being \u003ci\u003eBitBlt\u003c/i\u003eed into the underlying HWND's device context (or HDC). Setting the WS_EX_LAYOUTRTL property of the top level Chromium HWND means that any text drawn into the DIB (using Windows' DrawText API) will need to be drawn such that each and every glyph is mirrored (so that flipping the DIB into the mirrored HDC will display the correct text). The problem with this method is that it will break ClearType because ClearType text rendering is direction dependant (which subpixels the ClearType algorithm sets depends on where the subpixels are relative to the drawn glyphs); in other words, flipping a bitmap containing ClearType is guaranteed to break the cripsness of the text.\r\n\t\u003c/li\u003e\r\n\u003cbr /\u003e\r\n\t\r\n\u003cli\u003e\u003ci\u003eChromeViews\u003c/i\u003e is a portable framework and therefore it does not make much sense to use a platform-specific solution for mirroring in code that needs to remain portable.\u003c/li\u003e\r\n\t\u003cbr /\u003e\r\n\t\r\n\u003cli\u003eThe Windows mirroring applies to the HWND hierarchy of windows and controls. \u003ci\u003eChromeViews\u003c/i\u003e has its own concept of UI elements hierarchy and it is not possible to use the Windows API for mirroring and still have the flexibility of controlling mirroring in a \u003ci\u003eView\u003c/i\u003e subclass granularity; in other words, not every \u003ci\u003eView\u003c/i\u003e subclass is associated with a Windows HWND handle and it is therefore not possible to control the setting of each and every Chromium UI element by only using HWND mirroring. As we'll see later on, the Chromium mirroring infrastructure does use Windows native mirroring for the Chromium native UI controls.\u003c/li\u003e\r\n\u003c/ul\u003e\r\n\r\n\u003ch3\u003e\u003ca name\u003d\"TOC-ChromeViews::View-mirroring-support\" /\u003eChromeViews::View mirroring support \u003c/h3\u003e\r\n\u003cp\u003eThe Chromium mirroring infrastructure and API resides mostly in the \u003ci\u003eChromeViews::View\u003c/i\u003e class since it is the base class for the majority of the Chromium browser UI elements. Before describing the interface, it is important to note that whenever we refer to the concept of 'locale' or 'current locale' we refer to the Chromium UI language. The locale concept entails more than just the UI language, but for the purpose of explaining the mirroring infrastructure, it is OK to ignore the other locale aspects or the logic Chromium uses in order to set the default locale.\u003c/p\u003e\r\n\u003cp\u003eJust like the Windows mirroring API, the corresponding Chromium API is designed in a way that frees individual GUI developers from the burden of programmatically mirroring UI elements and sub elements. However, the API has certain limitations and in some cases more mirroring-related code needs to be written for specific Chromium UI elements. Chromium \u003ci\u003eView\u003c/i\u003e subclasses that follow a certain set of conventions (described in \u003cb\u003eHow to write RTL-ready Chromium UI\u003c/b\u003e,  below), are going to work well in mirrored UIs and won't need to have additional code for handling right-to-left layout issues.

However, this is true only if the UI elements adhere to a certain set of conventions. Not following these rules when writing a UI element generally means that mirroring-specific code will need to be added to the element so that it is displayed correctly in right-to-left locales. This section describes the rules together with examples that demonstrate why not following these rules is problematic. Even though it is discouraged to put mirroring-specific code in a UI element (it is better to just follow the rules), this section shows how to handle mirroring manually in UI components. This is useful for UI component that, for whatever reason, can not be written in a manner that allows the mirroring infrastructure to display the component correctly in RTL locales.\u003c/p\u003e\r\n\u003cp\u003e\u003cb\u003eRule #1: represent UI sub elements as child \u003ci\u003eView\u003c/i\u003es\u003c/b\u003e\u003c/p\u003e\r\n\u003cp\u003eThe Chromium toolbar example presented earlier is an example of a Chromium \u003ci\u003eView\u003c/i\u003e subclass that contains several child \u003ci\u003eView\u003c/i\u003es as its sub elements. The toolbar lays out the sub elements, but it does not do any rendering. Instead, rendering is done by the individual sub elements. In other words, for the toolbar, the 'leaf' elements in the UI tree are the only elements that draw graphics on the canvas during \u003ci\u003eView::Paint()\u003c/i\u003e. This method plays well with the mirroring infrastructure since the coordinate transformation can be easily applied to the bounds of the child elements. One of the Chromium UI components that does not adhere to this rule is the \u003ci\u003eTab\u003c/i\u003e (see chrome/browser/tabs/tab.h). The \u003ci\u003eTab\u003c/i\u003e contains three UI sub elements. A 'close' button, a title and a favicon. The button is represented as a \u003ci\u003eChromeView::Button\u003c/i\u003e child \u003ci\u003eView\u003c/i\u003e. The title and the favicon are both drawn directly on the canvas by the \u003ci\u003eTab\u003c/i\u003e class during \u003ci\u003eView::Paint()\u003c/i\u003e.

The title and the favicon, on the other hand, are not positioned in the same manner since they are not child views.

Alternatively the --no-nacl-gcc flag can be used when building the PNaCl, which will allow the build to complete but will result in a non-functional C++ exception handling runtime (this EH runtime is not needed to build any Chrome components, so you'd only need to build it if you want to also create a NaCl SDK for developers to use).\u003c/div\u003e\u003ch2\u003e\u003ca name\u003d\"TOC-PNaCl-in-browser-translator\" /\u003e\u003cspan style\u003d\"font-weight:normal\"\u003ePNaCl in-browser translator\u003c/span\u003e\u003c/h2\u003e\u003cdiv\u003eIf you want to enable PNaCl as well as NaCl in Chromium, the last component that needs to be built is the in-browser PNaCl translator component.

embedded device such as a Chromebook, the firmware is the first software that runs. It sets up the machine so that it can load the operating system and then transfers control to the OS. This general pattern applies to any architecture, but there are differences depending on the exact system architecture. For example, on ARM SoCs, it is common to have a boot ROM within the SoC that is capable of booting from various media and may set up basic clocks and peripherals.  \u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003eOn x86 systems, only the boot system is in SPI flash, and the firmware must deal with every aspect of setting up the machine.  Typically, a first stage firmware such as Coreboot (not covered in this guide) is used on x86 to deal with these complexities. On x86, part of the firmware stays resident even after the OS runs, whereas on ARM and most other architectures, the firmware is no longer in memory once control transfers to the OS.\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003ch3\u003e\u003ca name\u003d\"TOC-Firmware-Tasks-on-Chrome-OS\" /\u003eFirmware Tasks on Chrome OS\u003c/h3\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003eThe firmware sets up the basic peripherals such as the keyboard, display, mass storage, security chip (TPM), and SPI flash for its own use while it runs the steps to set up the machine. In Chrome OS, the firmware can be updated, so the system first checks whether an update exists and, if so, it loads the update and jumps to execute it. In normal cases, the OS is available and is loaded and started.  If a problem exists (for example, the OS is corrupt), the firmware enters recovery mode, which allows the user to insert media with a new OS. In developer mode, users can bypass Chrome OS security, or even the entire OS.\u003c/div\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003ch3\u003e\u003ca name\u003d\"TOC-U-Boot\" /\u003eU-Boot\u003c/h3\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003eU-Boot (Universal Boot) is a useful basis for firmware because it has wide architecture support and contains many drivers and subsystems.  Chrome OS uses an upstream version of U-Boot and adds its own verified boot infrastructure, which is linked to U-Boot.

linux.  It's not an explicit goal for us to provide a solution for OSX, but a cross platform solution would be preferred.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\n\u003cb\u003eBackground\u003c/b\u003e\u003cbr /\u003e\r\nOn Windows, we store resources in dll files.  They are compiled into dll files using Visual Studio's resource compiler (rc.exe) which read .rc files.  .rc files are just lists of resource ids and the actual file on disk that they represent or an inlined string (for translations).  From code we reference the resource using the resource ids which are found in a header file.  For localized strings, we use GRIT to generate the .rc files.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nMost resources are compiled directly into chrome.dll.  There are two exceptions: theme images are in theme.dll and languages are in locale specific dlls (e.g., en-US.dll).  Having a separate theme.dll was to make it easier to transition to a real theming system and to make it easier for UI developers to test changes to the theme (by not having to re-link chrome.dll).  Locale data is in a separate dll because we would like to reduce the chrome download size by providing localized builds of chrome.  One would only need to download the strings for languages that are of interest.  This doesn't save much in download right now, but if ICU data files could be split into chunks, then it could save \u0026gt; 1mb of download.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nOn Linux, data resources are normally just kept as files on disk that are read during runtime.  The location of these resources are normally hard-coded into the binary at compile time.  Localized strings are normally handled using gettext.  From code, gettext uses the English string to reference the localized string.  gettext has another interface called catgets which can be used to reference strings using a resource id.  This is pretty similar to what we do on Windows.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\n\u003cb\u003eRequirements\u003c/b\u003e\u003cbr /\u003e\r\nThe standard Linux method of reading data resources from disk seems like a non-starter because we use lots of small image files to create the Chromium UI.  We could possibly work around this by image spriting, but we would still read more files from disk that windows currently is.  Also, while catgets might be a good solution for localized strings, it doesn't handle binary data.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\n\u003cb\u003eDesign Ideas\u003c/b\u003e\u003cbr /\u003e\r\nRoll our own resource handling.  This would involve a disk format for data resources and strings, and code to load the file and read ranges of bytes from the file.  To create the disk format, we would use a python script that reads the .rc files at compile time and generates our data file.  This would be similar to the Visual Studio resource compiler except it wouldn't be able to put data directly into the dll (shared object).  The code to load the file and read a range of bytes would exist in base so we can load data resources (like the tld data file) in sub module tests.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nThe main drawback is that we won't be able to bundle binary data blobs directly into the chrome binary.  We currently do this for everything other than the theme images and localized strings.  Putting the data directly into chrome makes it easier for the renderer process to access resources because it doesn't have to go to disk.  To work around this, on linux we would have to load the data resource in the renderer process before sandboxing it.  This is similar to what we already do for localized resources in the renderer process.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nThis has the benefit that we don't need to maintain different resource file definitions across platforms, it would be sufficient to update the main .rc file.  We also don't have to change any of the callers or the current use of resource IDs throughout the code base.  We just need to change ResourceBundle to handle the new data file.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nThis would also work cross platform, so we may eventually be able to move Windows over to it so we all use the same system.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nData File Format version

That means if e.g. the style system is running, Javascript can’t receive new events. More obviously, it also means that other JavaScript events (such as a timer firing, or an XHR success callback, etc) will block JS events that may be very timely -- like touch events. NB this essentially means \u003c/span\u003e\u003cspan style\u003d\"font-size:15px;font-family:Arial;font-weight:bold;vertical-align:baseline;white-space:pre-wrap;background-color:transparent\"\u003eapplications responding to touch input must consider the JavaScript main thread the application’s UI thread, and not block it for more than a few milliseconds\u003c/span\u003e\u003cspan style\u003d\"font-size:15px;font-family:Arial;vertical-align:baseline;white-space:pre-wrap;background-color:transparent\"\u003e.\u003c/span\u003e\u003c/p\u003e\u003cbr /\u003e\u003cp dir\u003d\"ltr\" style\u003d\"line-height:1.15;margin-top:0pt;margin-bottom:0pt\"\u003e\u003cspan style\u003d\"font-size:15px;font-family:Arial;vertical-align:baseline;white-space:pre-wrap;background-color:transparent\"\u003eThe above explanation simplifies a lot, but should be enough to get going. Two exceptions worth pointing out though: first, scrolling is “special” in that it happens outside of the main JavaScript context, and scroll positions are asynchronously reported back to the main thread and updated in the DOM. This prevents janky scrolling even if the page executes a lot of JavaScript, but it can get in the way if the page is well-behaved and wants to respond to scrolling. Second, the pipeline above isn’t strictly hierarchically ordered -- that is, sometimes you can update style without needing to re-lay-out anything and without needing to repaint anything. A key example is CSS transforms, which don’t alter layout and hence can skip directly from style resolution (e.g. changing the transform offset) to compositing if the necessary content is already painted.\u003c/span\u003e\u003c/p\u003e\u003cbr /\u003e\u003ch3 dir\u003d\"ltr\" style\u003d\"line-height:1.15;margin-top:8pt;margin-bottom:0pt\"\u003e\u003ca name\u003d\"TOC-Introducing-Frameviewer\" /\u003e\u003cspan style\u003d\"font-family:Trebuchet MS;color:rgb(102,102,102);vertical-align:baseline;white-space:pre-wrap;background-color:transparent\"\u003eIntroducing Frameviewer\u003c/span\u003e\u003c/h3\u003e\u003cbr /\u003e\u003cp dir\u003d\"ltr\" style\u003d\"line-height:1.15;margin-top:0pt;margin-bottom:0pt\"\u003e\u003cspan style\u003d\"font-size:15px;font-family:Arial;vertical-align:baseline;white-space:pre-wrap;background-color:transparent\"\u003eFor the rest of this document to make sense you’ll need to get set up to record frame viewer traces.

or query the content layer (e.g., sending IPC, asking BrowserContext if it is off the record). To enable abstracting these interactions, the general pattern is to introduce a FooDriver interface. This interface will live in the core code of the component, and an instance of it will be injected into this core code on instantiation. The content-based and iOS drivers of the component will each have a concrete subclass of the FooDriver interface.\u003c/font\u003e\u003c/div\u003e\u003cdiv style\u003d\"font-weight:normal\"\u003e\u003cfont size\u003d\"3\"\u003e\u003cbr /\u003e\u003c/font\u003e\u003c/div\u003e\u003cdiv style\u003d\"font-weight:normal\"\u003e\u003cfont size\u003d\"3\"\u003eExample: \u003ca href\u003d\"https://codereview.chromium.org/16286020/\"\u003ehttps://codereview.chromium.org/16286020/\u003c/a\u003e\u003c/font\u003e\u003c/div\u003e\u003ch3 style\u003d\"font-weight:bold\"\u003e\u003ca name\u003d\"TOC-Abstracting-WebContentsObserver\" /\u003eAbstracting WebContentsObserver\u003c/h3\u003e\u003cdiv style\u003d\"font-weight:normal\"\u003e\u003cfont size\u003d\"3\"\u003eYou can make the content-based FooDriver implementation be a WebContentsObserver.

But the type of symbols that you see going through while executing dds gives you a rough idea of how the flow ends up at the code that crashes.\u003c/div\u003e\r\n\u003cbr /\u003e\r\n\u003cdiv class\u003d\"sites-codeblock sites-codesnippet-block\"\u003e\r\n\u003cfont face\u003d\"'courier new', monospace\" size\u003d\"2\"\u003e\r\n\u003ccode\u003e\r\n\u003cdiv\u003e0:006\u0026gt; k \u003d 0465e0ac  0465e0ac  0465e0ac  \u003c/div\u003e\r\n\u003cdiv\u003eChildEBP RetAddr  \u003c/div\u003e\r\n\u003cdiv\u003eWARNING: Frame IP not in any known module.

The directory is shared between threads and provides transactional semantics for all changes triggered by local model changes as well as changes coming with server updates. The directory provides a decoupling between the model facing part of Sync Engine and the server facing part of the engine running on the sync thread. For example, if there is a local change, it first gets updated in the directory, marked as unsynced, then sync thread separately reads it from the directory when it is time to commit changes to the server. This makes the directory the centerpiece of the current design. But at the same time this makes the directory the the main bottleneck - an exclusive access to the directory is needed for any operation with it. Also since the directory keeps all the data and sync metadata readily available in memory there the scalability of this approach is limited to tens of thousands of entries. \u003c/font\u003e\u003c/span\u003e\u003c/div\u003e\u003cbr /\u003e\u003cp dir\u003d\"ltr\" style\u003d\"line-height:1.38;margin-top:0pt;margin-bottom:0pt\"\u003e\u003cspan style\u003d\"font-family:Arial;font-size:14.6667px;white-space:pre-wrap;line-height:1.38;background-color:transparent\"\u003eThe idea is to decentralize Sync storage and to shift the storage responsibility, at least conceptually, from Sync engine to Sync clients e.g. native models that own the actual synced data. The core Sync components don’t have to know anything about the storage, they just pass messages containing sync data asynchronously all the way to model type specific sync service (the adapter between Sync engine and the native model). The sync service encapsulates the storage capable of storing sync metadata along with the model data. The storage implementation is responsible for ensuring consistency of the model data with sync metadata. \u003c/span\u003e\u003c/p\u003e\u003cbr /\u003e\u003cp dir\u003d\"ltr\" style\u003d\"line-height:1.38;margin-top:0pt;margin-bottom:0pt\"\u003e\u003cspan style\u003d\"font-size:14.6667px;font-family:Arial;vertical-align:baseline;white-space:pre-wrap;background-color:transparent\"\u003eThat doesn’t mean every native model has to roll out its own storage.

In most cases it would be a thin adapter over the existing storage that allows Sync to bundle Sync metadata with the corresponding data entities or to store Sync metadata side-by-side (e.g. in a separate table in case of SQLite DB). The expectation is that in most cases no or very little changes would be needed to the existing native model and/or storage implementations.

The key difference between this component and currently existing counterparts is that the existing implementation propagates sync changes through the shared directory by writing updates to the directory and querying uncommitted local changes from the directory. The USS based implementation achieves the same by exchanging the data across the thread boundary with the processor. The worker provides a short term in-memory cache for pending committed entities waiting for the next scheduled sync cycle or for the network connection to the server. If the application terminates before successfully committing pending entities to the server, the processor running on the model, based on the last saved snapshot of the metadata, can still determine all the entities with unfinished commit and re-commit them through the engine pipeline.\u003c/span\u003e\u003c/p\u003e\u003cbr /\u003e\u003cp dir\u003d\"ltr\"

The model type specific service (ModelTypeService implementation) is responsible for keeping the sync metadata in sync with the data changes. In some cases the metadata consistency with the data is guaranteed by owning the storage implementation and in some cases that is provided by piggybacking on the native storage implementation and understanding how a particular native storage persisting works (see the implementation patterns section above).\u003c/span\u003e\u003c/p\u003e\u003cbr /\u003e\u003cp dir\u003d\"ltr\" style\u003d\"line-height:1.38;margin-top:0pt;margin-bottom:0pt\"\u003e\u003cspan style\u003d\"font-size:14.6667px;font-family:Arial;vertical-align:baseline;white-space:pre-wrap;background-color:transparent\"\u003eAnother source of inconsistency is delayed startup of Sync or turning Sync off temporarily (which is possible on mobile platforms).

So, we will have a settings daemon,\r\nsettingsd, that manages write access to the system settings.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nWhen the first user logs in, we generate an RSA keypair and store the private half in his encrypted home directory, exporting the public half via settingsd.  All requests to update the signed settings store (which includes the whitelist) must contain a valid signature generated with the owner's private key.  When settingsd receives a request for the value of a system setting, it returns the signature over that value along with the requested data.  The requesting process then verifies this signature, ensuring that only values which are correctly signed by the Owner are respected.  Of course, a root-level exploit could replace the exported Owner public key.  As stated above, though, the game is already over in this case.\u003c/div\u003e\u003c/div\u003e\u003c/td\u003e\u003c/tr\u003e\u003c/tbody\u003e\u003c/table\u003e\u003c/div\u003e"},"link":[{"rel":"http://schemas.google.com/sites/2008#parent","type":"application/atom+xml","href":"https://sites.google.com/feeds/content/chromium.org/dev/3366051319303255070"},{"rel":"alternate","type":"text/html","href":"https://sites.google.com/a/chromium.org/dev/chromium-os/chromiumos-design-docs/user-accounts-and-management"},{"rel":"http://schemas.google.com/sites/2008#revision","type":"application/atom+xml","href":"https://sites.google.com/feeds/revision/chromium.org/dev/2353873424158359748"},{"rel":"self","type":"application/atom+xml","href":"https://sites.google.com/feeds/content/chromium.org/dev/2353873424158359748"},{"rel":"edit","type":"application/atom+xml","href":"https://sites.google.com/feeds/content/chromium.org/dev/2353873424158359748"}],"author":[{}],"sites$pageName":{"$t":"user-accounts-and-management"},"sites$revision":{"$t":"6"}},{"gd$etag":"\"WSl7JmA_\"","id":{"$t":"https://sites.google.com/feeds/content/chromium.org/dev/998207241578066502"},"published":{"$t":"2009-11-19T19:03:43.296Z"},"updated":{"$t":"2016-08-04T08:50:55.914Z"},"app$edited":{"xmlns$app":"http://www.w3.org/2007/app","$t":"2016-08-04T08:50:54.290Z"},"category":[{"scheme":"http://schemas.google.com/g/2005#kind","term":"http://schemas.google.com/sites/2008#webpage","label":"webpage"}],"title":{"$t":"Reporting a Crash Bug"},"content":{"type":"xhtml","$t":"\u003cdiv xmlns\u003d\"http://www.w3.org/1999/xhtml\"\u003e\u003ctable cellspacing\u003d\"0\" class\u003d\"sites-layout-name-one-column sites-layout-hbox\"\u003e\u003ctbody\u003e\u003ctr\u003e\u003ctd class\u003d\"sites-layout-tile sites-tile-name-content-1\"\u003e\u003cdiv dir\u003d\"ltr\"\u003e\u003cp\u003eIf you are planning to report a crash bug, please make sure you include enough information for debugging purpose.\u003c/p\u003e\r\n\r\n\u003cul\u003e\u003cli\u003eMake sure you have the latest Chrome version (on Windows go to Chrome Options-\u0026gt;About Google Chrome)\u003c/li\u003e\r\n\u003cli\u003eMake sure you have \u003ca href\u003d\"https://support.google.com/chrome/answer/96817\" target\u003d\"_blank\"\u003ecrash reporting enabled\u003c/a\u003e.\u003c/li\u003e\u003cli\u003eTry to get exact reproducible steps for the crash, if possible.\u003c/li\u003e\r\n\u003cli\u003eTry to also provide more debugging info by either: .\u003c/li\u003e\r\n\u003cul\u003e\u003cli\u003e\u003cb\u003eReporting the crash directly\u003c/b\u003e: If possible, and you are using Google Chrome, enable crash reporting in Google Chrome's settings: go to chrome://chrome/settings, click \"Show advanced settings...\" and in the Privacy section select select \"Automatically send usage statistics and crash reports to Google\", then see the instructions below for getting a crash ID.

It's a bit hard to get Qemu built in the Chrome OS build system at present, so I've got a directory containing Qemu, its libraries and BIOS files, and scripts to chroot to that directory and run Qemu. Access to devices, where needed, is provided via bind-mounts. The setup sounds a bit kludgy but works well for me; nevertheless, we welcome improvements. What we'd most prefer is to get this patch series into Chrome OS, so we have qemu as part of a \"real\" build.\u003c/p\u003e\r\n\u003cp\u003e\u003ca href\u003d\"https://gerrit.chromium.org/gerrit/#/c/15445/\"\u003ehttps://gerrit.chromium.org/gerrit/#/c/15445/\u003c/a\u003e\u003c/p\u003e\r\n\u003cp\u003eFWIW, this particular instance of qemu was built on arch Linux, lost, sadly, when my Air was stolen.\u003c/p\u003e\u003ch3\u003e\u003ca name\u003d\"TOC-Background\" /\u003eBackground\u003c/h3\u003e\u003cp\u003eThe firmware on Chrome OS devices will clear the VMX bits during boot.  This means that support is disabled, but it is not locked such that runtime cannot change things.  This keeps things secure during initial boot, but doesn't lock out people from enabling things themselves in the kernel.  Otherwise, they'd have to resort to modifying the firmware and that's always a tricky proposition (make a mistake and you have a brick).\u003c/p\u003e\u003cp\u003eWhen the Chrome OS kernel boots up, it will look for the \u003ccode\u003edisablevmx\u003d[on|off]\u003c/code\u003e option on the kernel command line.  If it is set to \u003ccode\u003eoff\u003c/code\u003e, then VMX support will be enabled.  For all other situations, we disable VMX and lock the bits so they cannot be turned back on.  This keeps the system secure.\u003c/p\u003e\u003cp\u003eCurrent Chrome OS systems all ship with KVM disabled.  That means you need to currently build a custom kernel yourself in order to get KVM support.\u003c/p\u003e\u003ch3\u003e\u003ca name\u003d\"TOC-Board-Specific-Notes\" /\u003eBoard Specific Notes\u003c/h3\u003e\u003cp\u003eBe aware that on earlier Chrome OS devices, the firmware contained bugs such that they locked VMX support during power on.  It's known to affect:\u003c/p\u003e\u003cul\u003e\u003cli\u003e\u003ca href\u003d\"https://sites.google.com/a/chromium.org/dev/chromium-os/developer-information-for-chrome-os-devices/samsung-series-5-chromebook\"\u003eSeries 5 Chromebook\u003c/a\u003e\u003c/li\u003e\u003cli\u003e\u003cspan style\u003d\"font-size:10pt\"\u003e*\u003ca href\u003d\"https://sites.google.com/a/chromium.org/dev/chromium-os/developer-information-for-chrome-os-devices/samsung-sandy-bridge\"\u003eSamsung Series 5 550\u003c/a\u003e\u003c/span\u003e\u003c/li\u003e\u003cli\u003e\u003cspan style\u003d\"font-size:10pt\"\u003e*\u003ca href\u003d\"https://sites.google.com/a/chromium.org/dev/chromium-os/developer-information-for-chrome-os-devices/samsung-sandy-bridge\"\u003eSamsung Series 3 Chromebox\u003c/a\u003e\u003c/span\u003e\u003c/li\u003e\u003c/ul\u003e\u003cp\u003eFor devices marked with a *, you might be able to restore support by hacking the firmware.  Please see the respective device pages for more details.\u003c/p\u003e\r\n\r\n\u003ch2\u003e\u003ca name\u003d\"TOC-Building-Chromium-OS-w-KVM\" /\u003eBuilding Chromium OS w/KVM\u003c/h2\u003e\r\n\u003cp\u003eTo start, you're going to need an image that has the KVM modules.

Non-confidential features can be published on the Chrome Web Store and installed manually for early testing. Confidential extensions can be enabled only for trusted testers so they are invisible to the public. Extensions can use content scripts to do script injection and can use page actions and browser actions to provide UI outside the content area. Extensions can also use NaCL, which has full access to the Pepper API.\u003c/span\u003e\u003c/p\u003e\u003cbr /\u003e\u003cp dir\u003d\"ltr\" style\u003d\"line-height:1.38;margin-top:0pt;margin-bottom:0pt\"\u003e\u003cspan style\u003d\"font-size:14.6667px;font-family:Arial;vertical-align:baseline;white-space:pre-wrap;background-color:transparent\"\u003eComponent extensions (i.e. extensions automatically installed into Chrome) are also a prototyping option, but should only be used if there is something needed that a regular extension cannot do. Extensions should strive to only execute on explicit user action and never on startup. Persistent background pages should be avoided. Event pages should only be used for infrequent items like push messaging, hardware events, alarms etc…, but not common events like navigation. If you need to do something that imposes a constant load or requires updating state on each navigation, consult the extensions team; they might be able to provide a declarative API so the job can be done with low impact. Failing that, consult with chrome-eng-review@ if you need to deviate from these guidelines.\u003c/span\u003e\u003c/p\u003e\u003c/span\u003e\u003c/div\u003e\u003c/td\u003e\u003c/tr\u003e\u003c/tbody\u003e\u003c/table\u003e\u003c/div\u003e"},"link":[{"rel":"http://schemas.google.com/sites/2008#parent","type":"application/atom+xml","href":"https://sites.google.com/feeds/content/chromium.org/dev/3863791766242792620"},{"rel":"alternate","type":"text/html","href":"https://sites.google.com/a/chromium.org/dev/developers/design-documents/ui-development-practices"},{"rel":"http://schemas.google.com/sites/2008#revision","type":"application/atom+xml","href":"https://sites.google.com/feeds/revision/chromium.org/dev/987968386620844029"},{"rel":"self","type":"application/atom+xml","href":"https://sites.google.com/feeds/content/chromium.org/dev/987968386620844029"},{"rel":"edit","type":"application/atom+xml","href":"https://sites.google.com/feeds/content/chromium.org/dev/987968386620844029"}],"author":[{"name":{"$t":"Mike Wasserman"},"email":{"$t":"msw@chromium.org"}}],"sites$pageName":{"$t":"ui-development-practices"},"sites$revision":{"$t":"3"}},{"gd$etag":"\"Wyl7JmA9\"","id":{"$t":"https://sites.google.com/feeds/content/chromium.org/dev/837940195398530819"},"published":{"$t":"2008-11-12T00:06:54.354Z"},"updated":{"$t":"2016-06-29T22:13:38.480Z"},"app$edited":{"xmlns$app":"http://www.w3.org/2007/app","$t":"2016-06-29T22:13:34.832Z"},"category":[{"scheme":"http://schemas.google.com/g/2005#kind","term":"http://schemas.google.com/sites/2008#webpage","label":"webpage"}],"title":{"$t":"Setting up Visual Studio Debugger Visualizers"},"content":{"type":"xhtml","$t":"\u003cdiv xmlns\u003d\"http://www.w3.org/1999/xhtml\"\u003e\u003ctable cellspacing\u003d\"0\" class\u003d\"sites-layout-name-one-column sites-layout-hbox\"\u003e\u003ctbody\u003e\u003ctr\u003e\u003ctd class\u003d\"sites-layout-tile sites-tile-name-content-1\"\u003e\u003cdiv dir\u003d\"ltr\"\u003e\r\n\u003cdiv dir\u003d\"ltr\"\u003e\r\n\u003cdiv dir\u003d\"ltr\"\u003e\r\n        \r\n        \r\n  \r\n\r\n        \r\n      \r\n        \r\n        \r\n      \r\n          \r\n        \r\n        \r\n  \r\n\r\n        \r\n      \r\n        \r\n        \r\n      \r\n          \r\n        \r\n        \r\n  \r\n\r\n        \r\n      \r\n        \r\n        \r\n      \r\n          \r\n        \r\n        \r\n  \r\n\r\n        \r\n      \r\n        \r\n        \r\n      \r\n          \r\n        \r\n        \r\n  \r\n\r\n        \r\n      \r\n        \r\n        \r\n      \r\n          \r\n        \r\n        \r\n  \r\n\r\n        \r\n      \r\n        \r\n        \r\n      \r\n          \r\n        \r\n        \r\n  \r\n\r\n        \r\n        \r\n      \r\n        \r\n        \r\n      \r\n          \r\n        \r\n        \r\n        \r\n      \r\n        \r\n\r\n        \r\n\r\n      \r\n        \r\n        \r\n      \r\n        \r\n        \r\n      \r\n          \r\n        \r\n        \r\n        \r\n      \r\n        \r\n\r\n        \r\n\r\n      \r\n        \r\n        \r\n      \r\n        \r\n        \r\n      \r\n          \r\n        \r\n        \r\n        \r\n      \r\n        \r\n\r\n        \r\n\r\n      \r\n        \r\n        \r\n      \r\n        \r\n        \r\n      \r\n          \u003cdiv class\u003d\"sites-embed-align-left-wrapping-off\"\u003e\u003cdiv class\u003d\"sites-embed-border-off sites-embed\" style\u003d\"width:250px;\"\u003e\u003cdiv class\u003d\"sites-embed-content sites-embed-type-toc\"\u003e\u003cdiv class\u003d\"goog-toc sites-embed-toc-maxdepth-6\"\u003e\u003cp\u003eContents\u003c/p\u003e\u003col class\u003d\"goog-toc\"\u003e\u003cli class\u003d\"goog-toc\"\u003e\u003ca href\u003d\"#TOC-Introduction\"\u003e\u003cstrong\u003e1 \u003c/strong\u003eIntroduction\u003c/a\u003e\u003c/li\u003e\u003cli class\u003d\"goog-toc\"\u003e\u003ca href\u003d\"#TOC-Definitions\"\u003e\u003cstrong\u003e2 \u003c/strong\u003eDefinitions\u003c/a\u003e\u003c/li\u003e\u003cli class\u003d\"goog-toc\"\u003e\u003ca href\u003d\"#TOC-References\"\u003e\u003cstrong\u003e3 \u003c/strong\u003eReferences\u003c/a\u003e\u003c/li\u003e\u003c/ol\u003e\u003c/div\u003e\u003c/div\u003e\u003c/div\u003e\u003c/div\u003e\r\n        \r\n      \r\n        \r\n      \r\n        \r\n      \r\n        \r\n      \r\n        \r\n      \r\n        \r\n      \r\n        \r\n      \r\n        \r\n      \r\n        \r\n      \r\n        \r\n      \r\n\u003ch2\u003e\u003ca name\u003d\"TOC-Introduction\" /\u003eIntroduction\u003cbr /\u003e\r\n\u003c/h2\u003e\r\n\u003cp\u003eVisual Studio (2013 and 2015) allows you to plug in additional \"visualizers\" to display data in the watch windows.

upload, install, and remove packages that are necessary to control a device under test (DUT).  Each package is a collection of files that is tarred and bzipped (into a *.tar.bz2 file) to facilitate the transferring of files onto the DUT.  When transferring packages to a DUT, the system computes an MD5 checksum for each package to determine whether or not any previously-installed package has changed and needs to be re-installed.  A package is only installed if it has changed according to the checksum (or, of course, if the package is not already on the

Once Chromium has determined it can search a site, any time the user types the URL of the site into the Omnibox the user is offered the ability to search the site. Once the user presses tab, then types in a string and presses the enter, the site is searched and the results shown to the user. It's important to note the search is done by the site itself, not Google or Chromium.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nChromium provides two heuristics that automatically add a site to the list of searchable sites. The following describes these heuristics:\u003cbr /\u003e\r\n\u003cbr /\u003e\r\n1. On your site's homepage provide a link to an \u003ca href\u003d\"http://www.opensearch.org/Specifications/OpenSearch/1.1#OpenSearch_description_document\" rel\u003d\"nofollow\"\u003eOpenSearch description document\u003c/a\u003e. The link to the OSDD is placed in the head of the html file. For example:\u003cbr /\u003e\r\n\u003cpre\u003e\u0026lt;head\u0026gt;\r\n \u0026lt;link type\u003d\"application/opensearchdescription+xml\" rel\u003d\"search\"\r\n       href\u003d\"url_of_osdd_file\"/\u0026gt;\r\n\u0026lt;/head\u0026gt;\r\n\u003c/pre\u003e\r\n\r\nThe important part of this document is the URL used to search your site. The following is an example that contains the bare minimum needed, see the \u003ca href\u003d\"http://www.opensearch.org/Specifications/OpenSearch/1.1#OpenSearch_description_document\" rel\u003d\"nofollow\"\u003eOpenSearch description document specification\u003c/a\u003e for the list of values you can specify.\r\n\r\n\u003cpre\u003e\u0026lt;?xml version\u003d\"1.0\"?\u0026gt;\r\n\u0026lt;OpenSearchDescription xmlns\u003d\"\u003ca href\u003d\"http://a9.com/-/spec/opensearch/1.1/\" rel\u003d\"nofollow\" style\u003d\"color:rgb(42,93,176)\" target\u003d\"_blank\"\u003ehttp://a9.com/-/spec/opensearch/1.1/\u003c/a\u003e\"\u0026gt;\r\n \u0026lt;ShortName\u0026gt;Search My Site\u0026lt;/ShortName\u0026gt;\r\n \u0026lt;Description\u0026gt;Search My Site\u0026lt;/Description\u0026gt;\r\n \u0026lt;Url type\u003d\"text/html\" method\u003d\"get\" template\u003d\"\u003ca href\u003d\"http://my_site/%7BsearchTerms%7D\" rel\u003d\"nofollow\" style\u003d\"color:rgb(42,93,176)\" target\u003d\"_blank\"\u003ehttp://my_site/{searchTerms}\u003c/a\u003e\"/\u0026gt;\r\n\u0026lt;/OpenSearchDescription\u0026gt;\r\n\u003c/pre\u003e\r\n\r\nWhen the user presses enter in the Omnibox the string {searchTerms} in the url is replaced with the string the user typed.\u003c/span\u003e\u003cdiv\u003e\u003cbr /\u003e\u003c/div\u003e\u003cdiv\u003e\u003cspan style\u003d\"font-family:arial;font-size:13px\"\u003eYou can also include a suggestion service by adding another URL element with rel\u003d\"suggestions\" such as: \u003c/span\u003e\u003c/div\u003e\u003cdiv\u003e\u003cspan style\u003d\"font-family:arial;font-size:13px\"\u003e\u003cdiv\u003e\u003cfont face\u003d\"'courier new', monospace\"\u003e  \u0026lt;Url type\u003d\"application/json\" rel\u003d\"suggestions\" template\u003d\"http://my_site/suggest?q\u003d{searchTerms}\" /\u0026gt;\u003c/font\u003e\u003c/div\u003e\u003cdiv\u003e\u003cfont face\u003d\"arial, sans-serif\"\u003eIf you include this, the omnibox will use your suggestion service to provide query suggestions based on the user's partial query.\u003c/font\u003e\u003c/div\u003e\r\n\u003cbr /\u003e\r\n2. If the site does not provide a link to an OpenSearch description document but the user submits a form, then Chrome automatically adds the site to the list of searchable sites. There are a number of restrictions with this approach though. In particular the form must generate a GET, must result in a HTTP url, and the form must not have OnSubmit script. Additionally there must be only one input element of type text, no passwords, files or text areas and all other input elements must be in their default state.\u003cbr /\u003e\r\n\u003cbr /\u003e\r\nFor 1 and 2 Chromium only adds sites that the user navigated to without a path.

We often want to send messages\r\nusing a channel on another thread. For example, when the UI thread\r\nwants to send a message, it must go through the I/O thread. For this,\r\nwe use a \u003ccode\u003eIPC::ChannelProxy\u003c/code\u003e.\r\nIt has a similar API as the regular channel object, but proxies\r\nmessages to another thread for sending them, and proxies messages back\r\nto the original thread when receiving them. It allows your object\r\n(typically on the UI thread) to install a \u003ccode\u003eIPC::ChannelProxy::Listener\u003c/code\u003e\r\non the channel thread (typically the I/O thread) to filter out some\r\nmessages from getting proxied over. We use this for resource requests\r\nand other requests that can be handled directly on the I/O thread. \u003ccode\u003eRenderProcessHost\u003c/code\u003e installs a \u003ccode\u003eRenderMessageFilter\u003c/code\u003e object that does this filtering.\r\n\u003c/p\u003e\u003cp\u003e\r\n\u003c/p\u003e\u003ch2\u003e\u003ca name\u003d\"Synchronous_messages\"\u003e Synchronous messages \u003c/a\u003e\u003c/h2\u003e\r\n\u003cp\u003e\r\nSome messages should be synchronous from the renderer's perspective.\r\nThis happens mostly when there is a WebKit call to us that is supposed\r\nto return something, but that we must do in the browser. Examples of\r\nthis type of messages are spell-checking and getting the cookies for\r\nJavaScript. Synchronous browser-to-renderer IPC is disallowed to\r\nprevent blocking the user-interface on a potentially flaky renderer.\r\n\u003c/p\u003e\u003cp\u003e\r\n\u003cb\u003eDanger:\u003c/b\u003e Do not handle any synchronous messages in the\r\nUI thread! You must handle them only in the I/O thread. Otherwise, the\r\napplication might deadlock because plug-ins require synchronous\r\npainting from the UI thread, and these will be blocked when the\r\nrenderer is waiting for synchronous messages from the browser.\r\n\u003c/p\u003e\u003cp\u003e\r\n\u003c/p\u003e\u003ch3\u003e\u003ca name\u003d\"Declaring_synchronous_messages\"\u003e Declaring synchronous messages \u003c/a\u003e\u003c/h3\u003e\r\n\u003cp\u003e\r\nSynchronous messages are declared using the \u003ccode\u003eIPC_SYNC_MESSAGE_*\u003c/code\u003e\r\nmacros. These macros have input and return parameters (non-synchronous\r\nmessages lack the concept of return parameters). For a control function\r\nwhich takes two input parameters and returns one parameter, you would\r\nappend \u003ccode\u003e2_1\u003c/code\u003e to the macro name to get:\r\n\u003c/p\u003e\u003cp\u003e\r\n\u003c/p\u003e\u003cpre\u003eIPC_SYNC_MESSAGE_CONTROL2_1(SomeMessage,  // Message name\u003cbr /\u003e                            GURL, //input_param1\u003cbr /\u003e                            int, //input_param2\u003cbr /\u003e                            std::string); //result\u003c/pre\u003e\r\n\u003cp\u003e\r\nLikewise, you can also have messages that are routed to the view in which case you would replace \"control\" with \"routed\" to get \u003ccode\u003eIPC_SYNC_MESSAGE_ROUTED2_1\u003c/code\u003e. You can also have \u003ccode\u003e0\u003c/code\u003e\r\ninput or return parameters. Having no return parameters is used when\r\nthe renderer must wait for the browser to do something, but needs no\r\nresults. We use this for certain printing and clipboard operations.\r\n\u003c/p\u003e\u003cp\u003e\r\n\u003c/p\u003e\u003ch3\u003e\u003ca name\u003d\"Issuing_synchronous_messages\"\u003e Issuing synchronous messages \u003c/a\u003e\u003c/h3\u003e\r\n\u003cp\u003e\r\nWhen the WebKit thread issues a synchronous IPC request, the request object (derived from \u003ccode\u003eIPC::SyncMessage\u003c/code\u003e) is dispatched to the main thread on the renderer through a \u003ccode\u003eIPC::SyncChannel\u003c/code\u003e object (the same one is also used to send all asynchronous messages). The \u003ccode\u003eSyncChannel\u003c/code\u003e will block the calling thread when it receives a synchronous message, and will only unblock it when the reply is received.\r\n\u003c/p\u003e\u003cp\u003eWhile the WebKit thread is waiting for the synchronous reply,\r\nthe main thread is still receiving messages from the browser process.\r\nThese messages will be added to the queue of the WebKit thread for\r\nprocessing when it wakes up. When the synchronous message reply is\r\nreceived, the thread will be un-blocked. Note that this means that the\r\nsynchronous message reply can be processed out-of-order.\r\n\u003c/p\u003e\u003cp\u003eSynchronous messages are sent the same way normal messages are,\r\nwith output parameters being given to the constructor.
