[chromium-dev] chrome.sln switched to gyp (sort of)

[Bradley Nelson]

Hi All,
We've just landed a change to switch chrome.sln to be gyp generated.
This was accomplished with a bit of a temporary cheat.
The now generated chrome.sln continues to refer to the checked-in vcprojs.
This change will allow us to switch them over one by one (and will let us
roll out most of the major components which are working gyp generated,
without being blocked on the few that aren't).

This has a few weird (temporary) ramifications:

1. Changes to modules at the chrome module level still need to be made in
the checked in vcprojs, however, dependency information now comes from
chrome.gyp and installer/installer.gyp.
2. The future layout of chrome.sln is reflected now (even though the
projects are in their old locations). Do let me know if there are any
problems with the new layout (or if I missed something). The new layout
mimics the directory structure, with the one compression that lone vcprojs
in a directory with the same name get brought up a level.

With any luck we'll be able to land vcprojs gradually throughout the week.
We don't plan to bug everyone with announcements on each change, so here's a
good rule of thumb:
Since you are already updating the gyp files to keep the other platforms
working, take note of whether targets you change in chrome.gyp or
installer.gyp contain the setting: 'msvs_existing_vcproj'. These will
require you to change the checked in vcproj file, others will not.

Be sure to let us (sgk and I) know if you notice any regressions during this
process.

I compiled in VS2008 and Vista. It has shortest startup delay when I
ran it from both command line and open file Dlg.

 Great job indeed!

We should restore form values just like other browsers.  If we do not, then

This is not saved.  Other browsers only save this information sometimes as a
side-effect of navigating back to a page that still exists in the page
cache.  You cannot rely on a back navigation hitting the page cache in any
browser since the page cache is finite in size.

Not generally, to my knowledge.

Again, why don't you test it?  This is pretty easy to test too.

Thank you.  Sorry 3 more questions:

1. If I enter some values in form elements, and then load a new page
(before i clicked submit) , and the click back. Does that mean the
values I entered in each form element will be all gone? (since
chromium does not keep track)?

2. Does chromium cache JavaScript native code (since it compiles JS
files to native code)? When users load a new page and then hit back,
does chromium just use already compiled native code (instead of
compiling it from JS files again)?

3. "page cache, which holds the DOM of recently visited pages in a
frozen state". What about JavaScript context (e.g. values of
JavaScript can changed due to user interaction) of that page, Does it
save in memory too?
What about CSS properties values? Are those holding in memory as well?

If the resource is in the cache, it is used, regardless of whether it has
expired.

Does Chrome still issue HTTP requests and check if the cache control

No.

In this case the browser will do a network transaction for resources in the
cache which have expired.

Thank you.

But what do you mean when you said "cached content should always be
preferred even if it is stale"?
Does Chrome still issue HTTP requests and check if the cache control
of HTTP response before it pull the data from content cache?  If yes,
how is that 'flag' change anything?

Or how is navigating back different from load 1 page, kill the browser
(assume the page content is now saved in cache) and start the browser

[Darin Fisher]

When navigating back, we reload the page.  However, we set a flag to
indicate that cached content should always be preferred even if it is stale.
That is consistent with all other major browsers with one
exception:  some of the other major browsers implement a page cache,
which holds the DOM of
recently visited pages in a frozen state so that they can be quickly
restored when navigating back or forward.  Such browsers behave similarly to
Chrome when the page you are navigating back to is not found in the page
cache.

[chromium-dev] Re: [extensions] Text translate API proposal

[Alex Russell]

I understand the proposal, and am suggesting that having content  
scripts might be a saner thing to do if they need to do less custom  
stuff to get the job done. The API that locates the stuff could be  
separate, but the transformation code feels like a natural content- 
script task and one that I'd be pained to see another (parallel) API  
for.

[Anthony LaForge]

In our efforts to release early and release often we will have a feature
freeze this Friday (June 5th, 2009) for Mstone:3, prior to cutting our
anticipated beta branch.  Please focus your energies on closing out high
priority (0, 1, 2) mstone:3 issues.  If all is successful, this branch
release will start it's life on the Dev channel next week and as stability
permits will be promoted accordingly (official beta and stable releases TBD
at a later time).

[chromium-dev] API design, class and function naming

[Benjamin]

I recently went though and watch the various tech talk videos that
were put up.  In a number of cases the speaker mentioned how the
naming of a function/class could have been better or that it could be
confused with something else.  This was best highlighted in
"Chromium's multi-process architecture" when talking about RenderView
and the many different ways that developers might confuse that with
something else including WebKit's own RenderView.  Recently the "The
Little Manual of API Design" got put up online (pdf)
http://chaos.troll.no/~shausman/api-design/api-design.pdf  It is a
really good (and short) book and I highly recommend it.  It discusses
various ways to improve your API which is always a good thing
especially for a project where you want to encourage outside
contribution.

I guess I keep getting hung up on why this isn't execCommand() on a  
range. The hard bit is finding the text to "range-ify", and I think  
that bit might make sense as a new API, but in terms of actually  
transforming things, ISTM that we should go fix the DOM where isn't  
not good enough (yet).

[chromium-dev] [linux] nested messageloop patch landed

[Evan Martin]

Antoine wrote a patch to make nested message loops work on Linux.
  http://codereview.chromium.org/115812

It's always a bit scary touching the message loop code, but this will
fix two real issues we know about:
 - file save dialogs crash on some subset of platforms
 - copy and paste crashers

My plan: I am going to land this patch, see if it does anything
horrible in the next few days or two.
So if you suddenly start getting new crashers, let me know.  We can
always back it out.

[chromium-dev] How does chromium handle 'Back' functionality

[Lucius Fox]

Hi,

Lets say i have 1 tab and I load 3 sites.
1. www.cnn.com
2. www.yahoo.com
3. www.aol.com  <-- the current page

What happens when users click 'Back'?
does chromium keep www.yahoo.com/www.cnn.com in memory? if yes, how
many pages it can keep in memory?
Or chromium just reload the page from scratch ? (just like user type
'www.yahoo.com' again in the URL box? (and it appears faster since
some files (e.g. images/js files) are already in cache?

Thank you for any explanation.

[chromium-dev] Re: [extensions] Text translate API proposal

[Erik Kay]

Similar to the translate, this feature could be used to support sites that
use non-standard character set / font combinations (some indic websites
depend on downloadable fonts and custom character sets).

Also, if the API allowed styling of the text as opposed to just replacing
it, then I could imagine that it could be used for interesting markup /
highlighting (highlighting searched words, marking up grammar errors,
auto-likifying, etc.).  Perhaps this would defeat part of the point of this
approach to an API.

That is one of the things I was concerned about too. I thought about

[chromium-dev] [extensions] Text translate API proposal

[Aaron Boodman]

Some people have expressed interest in implementing a "translate this
page" feature as an extension. This can be done as a content script
today, but it requires heavy and tricky modification of the DOM which
could introduce compat and performance problems.

Because of these problems, I'm exploring the idea of implementing a
higher-level API exposed to the extension process. I'd love feedback
on the idea:

[chromium-dev] updating mouse pointer state

[Evan Stade]

Webkit updates the mouse pointer state (changes the cursor,
hover-over, etc.) whenever it gets a mouse move event. (It should also
do so when getting a scroll event, but doesn't, but that's a different
matter.) However, it only gets mouse move events when it has focus. If
you right click, a context menu pops up and the render view loses
focus. Currently on linux if you move the cursor over some area that
should change the cursor (say an edit area), then click, the context
menu goes away but the cursor stays the same as it was before the
context menu was popped up. If you move the mouse slightly, it will
refresh the cursor and other bits of cursor-position-related state.

I have a (some would say hacky) fix for this, which is to synthesize a
mouse move event and send it to the renderer every time it gains
focus: http://codereview.chromium.org/113987

On the other hand, this doesn't come up on Windows because the render
view receives a (real) mouse move event when the render view regains
focus *even if the user actually hasn't touched the mouse* (try
dismissing the context menu by pressing escape). So,

Q: does anyone know where this mouse move event comes from?
Q: is there a better fix?

[chromium-dev] Re: Creating a bookmarklet extension

[Zak]

So I tried putting the quotes around that string first, it was a quick
easy fix. It works! Except the URL that's pasted into the body is:

"chrome-extension://0002/
my_toolstrip.html"

So that's odd, but it makes sense in a way. How to fix, not entirely
certain. Tried replacing "document.title" and "document.location" with
"tab.title" and "tab.location" with no results, the button ceases to
work at that point.

And trying that div and script you posted actually didn't work, Aaron.
Both when put into an html file that's called by my_toolstrip and when
in my-toolstrip itself. Button is there, nothing happens on a press.
Could it be the tab.url and tab.title - I think I need something else
to make those work properly.

[chromium-dev] Re: An Introduction and a question

[sidchat]

The Editor in WebCore (Editor.cpp), which is a part of WebKit, asks
for the spelling of a word in line 1474. The spelling-check is
provided by us (Chromium) through the "glue" - in particular,
editor_client_impl.cc in method checkSpellingOfString. Now, this guy
uses a WebViewDelegate object to send message through the IPC to the
spellchecker residing in the browser process through
RenderView::SpellCheck (render_view.cc). This message is picked by
resource_message_filter.cc, which uses the function OnSpellCheck to
now formally ask the spellchecker object to tell it if the spelling is
right or wrong. As you pointed out, this has to be done in the IO
thread. Once it gets the answer, it sends a message back through IPC -
WebCore gets the answer, the editor is happy, and now you see an
underline.

This is the basic path, but you are most welcome to ping me, or drop
by my desk for questions/ideas. Also, Brett (brettw) is the guru of
this architecture, so you should definitely pass by him too for ideas.

Yes, also set a breakpoint in HttpNetworkTransaction::GetLoadState()
in src/net/http/http_network_transaction.cc.  That's the ultimate source
of the load states.

[chromium-dev] Re: Creating a bookmarklet extension

[Aaron Boodman]

[giving up keeping this on chromium-discuss]

Aha, I didn't look closely enough at the bookmarklet to see it was
trying to get the title and url of the current page. The first pass of
the tab API is complete now (yay rafaelw!). So you can do something
like:

chrome.tabs.getCurrent(null, function(tab) {
 // do something with tab.title and tab.url
});

So I guess the complete (untested) code would look like:

Gmail
This

function gmailThis() {
  chrome.tabs.getSelected(null, function(tab) {
var url = "http://mail.google.com/mail/?ui=1&view=cm&fs=1&tf=1&to=&su="; +
  encodeURIComponent(tab.title) + "&body=" +
  encodeURIComponent(tab.url);
var w = window.open(url, 'addwindow',
,'status=no,toolbar=no,width=575,height=545,resizable=yes');
setTimeout(function() {
  w.focus();
}, 200);
  });
}

[chromium-dev] Re: Creating a bookmarklet extension

[Aaron Boodman]

There is a bug in the code. The string %20250 needs to have single
quotes around it. If you add that, it works.

But there are better ways to write this since you're not constrained
to fit it all into a single javascript statement like you are with
bookmarklets. You can learn how by just doing some quick searches for
HTML, JavaScript, and onclick. There are many online tutorials.

The way I usually build the player is to run gyp (solution file generator)
on /media/media.gyp, which generates /media/media.sln

gyp is located under /tools/gyp/gyp.bat

[chromium-dev] Re: Creating a bookmarklet extension

[Zak]

You mean what I made that failed to work? my_toolstrip.html just
contains:

http://mail.google.com/mail/?
ui=1&view=cm&fs=1&tf=1&to=&su='+encodeURIComponent(document.title)
+'&body='+encodeURIComponent(document.location);w=window.open
(m,'addwindow','status=no,toolbar=no,width=575,height=545,resizable=yes');setTimeout
(function(){w.focus();},%20250);})();">
  Gmail This


I thought that since a bookmarklet is a bookmark with code in the url
field, if I put that same code in the onclick (which usually points to
a url) it would work. But unfortunately the button shows up in the bar
but does not do anything when clicked.

The overall goal is to make an extension that when clicked will open
up gmail with the url of the page you're currently viewing in the body
of the email. Gmail This, basically. If you can think of a different
way to accomplish this other than mangling a bookmarklet, that is
beyond my level of knowledge.

src/chrome/browser/cocoa/status_bubble_mac.mm is the UI that displays
the message. The message itself comes from the cross-platform code,
but you can probably trace that by setting some breakpoints in the UI
code.

I think simply searching the code is better than trying to maintain a

http://www.google.com/search?q=site:src.chromium.org/svn/trunk+atlbase++-stdafx+-third_party&hl=en&filter=0

There no more use of ATL in src/base/ at least. The biggest part to get rid
of ATL will be replacing CComObjectRootEx and CWindowImpl.

How do you compile the player?

[chromium-dev] Creating a bookmarklet extension

[Zak]

Hi,

I'm really not a coding person, but I followed the documentation
here:

http://dev.chromium.org/developers/design-documents/extensions/howto

and set up an extension. Instead of hello-world.html I put an html
file containing a script (a gmail-this-page bookmarklet). The code is
below:

[code]
javascript:(function(){m='http://mail.google.com/mail/?
ui=1&view=cm&fs=1&tf=1&to=&su='+encodeURIComponent(document.title)
+'&body='+encodeURIComponent(document.location);w=window.open
(m,'addwindow','status=no,toolbar=no,width=575,height=545,resizable=yes');setTimeout
(function(){w.focus();},%20250);})();
[/code]

When I click the extension on the bottom bar, it just opens up an html
page with that code written in plain text. Obviously I'm missing some
crucial step, and since I don't have a background in coding or
programming of any sort, I'm pretty lost. Evidently putting the
javascript in an html file is a wrong move - a different filetype
maybe?

Thanks. And ignore me if I'm wasting your time or whatever, I realize
I'm some newbie guy asking probably a dumb question, but I'd
appreciate any help getting this simple thing working.

[chromium-dev] Re: How does chromium load font during page rendering

[Eric Seidel]

Fonts are loaded when text is rendered.  FontDescription objects are
created and used to fetch Font objects from the FontCache which are
held off the RenderStyle for a RenderText node.  GyphPages are filled
lazily from the Font as glyphs are drawn.

Yes, we should have better documentation.  But sadly, WebKit doesn't.
You can always ask in #webkit on irc.webkit.org about pieces of WebKit
architecture.

Best advice is to just download and sniff around in WebKit code.  As
they say: "Use the the Source Luke!"

Look at things like PlatformFontData if you want to see how Skia,
CoreGraphics, etc. handle platform-specific font bits.  Font is the
class which knows how to answer all the questions like "how wide is
this gyph".

http://trac.webkit.org/browser/trunk/WebCore should have all the code
you care about.  It's possible that some of the platform/chromium
files you need are missing from WebKit's repository, for those you'd
have to look in:
http://src.chromium.org/viewvc/chrome/trunk/src/webkit/

[chromium-dev] How does chromium load font during page rendering

[Lucius Fox]

Hi,

Can you please point me to the code (for mac os) where chromium load
font during page rendering?
for example, chromium needs to load the font matrix for the font
specified by css/html for text to measure how much of it can fit on 1
line and wrap the rest for the next line?

Thank you.
