Adds new `--show-overlay-browser` command-line flag that creates an
overlay containing an Alloy-style BrowserView. The main BrowserView
may be Chrome- (default) or Alloy-style (add `--use-alloy-style`).
This overlay will only be added to standalone (non-popup) windows.
Popups triggered via the overlay will receive standard Alloy-style
handling in cefclient (e.g. Views-hosted window). Add
`--use-default-popup` for default popup handling.
Chrome runtime only supports creation of a Views-hosted DevTools
popup in ChromeBrowserDelegate::CreateDevToolsBrowser if the parent
is also Views-hosted.
To test:
- Run `cefclient --use-native`
- Right click, select "Show DevTools"
- Close both windows and the app should exit
Set enable_alloy_bootstrap=false to build with Alloy bootstrap code
removed. Extension API is documented as deprecated in comments but
not compiled out with this arg.
Split the Alloy runtime into bootstrap and style components. Support
creation of Alloy style browsers and windows with the Chrome runtime.
Chrome runtime (`--enable-chrome-runtime`) + Alloy style
(`--use-alloy-style`) supports Views (`--use-views`), native parent
(`--use-native`) and windowless rendering
(`--off-screen-rendering-enabled`).
Print preview is supported in all cases except with windowless rendering
on all platforms and native parent on MacOS. It is disabled by default
with Alloy style for legacy compatibility. Where supported it can be
enabled or disabled globally using `--[enable|disable]-print-preview` or
configured on a per-RequestContext basis using the
`printing.print_preview_disabled` preference. It also behaves as
expected when triggered via the PDF viewer print button.
Chrome runtime + Alloy style behavior differs from Alloy runtime in the
following significant ways:
- Supports Chrome error pages by default.
- DevTools popups are Chrome style only (cannot be windowless).
- The Alloy extension API will not supported.
Chrome runtime + Alloy style passes all expected Alloy ceftests except
the following:
- `DisplayTest.AutoResize` (Alloy extension API not supported)
- `DownloadTest.*` (Download API not yet supported)
- `ExtensionTest.*` (Alloy extension API not supported)
This change also adds Chrome runtime support for
CefContextMenuHandler::RunContextMenu (see #3293).
This change also explicitly blocks (and doesn't retry) FrameAttached
requests from PDF viewer and print preview excluded frames (see #3664).
Known issues specific to Chrome runtime + Alloy style:
- DevTools popup with windowless rendering doesn't load successfully.
Use windowed rendering or remote debugging as a workaround.
- Chrome style Window with Alloy style BrowserView (`--use-alloy-style
--use-chrome-style-window`) does not show Chrome theme changes.
To test:
- Run `ceftests --enable-chrome-runtime --use-alloy-style
[--use-chrome-style-window] [--use-views|--use-native]
--gtest_filter=...`
- Run `cefclient --enable-chrome-runtime --use-alloy-style
[--use-chrome-style-window]
[--use-views|--use-native|--off-screen-rendering-enabled]`
- Run `cefsimple --enable-chrome-runtime --use-alloy-style [--use-views]`
Wait for the OnRequestContextInitialized callback before using a
non-global CefRequestContext.
Use default handling of --load-extension for Chrome runtime (fixes#3529).
Adds a new CefBrowserProcessHandler::OnAlreadyRunningAppRelaunch
callback for when an already running app is relaunched with the
same CefSettings.root_cache_path.
Client apps should check the CefInitialize() return value for early
exit of the relaunch source process.
A modal dialog is a child CefWindow that implements some special behaviors
relative to a parent CefWindow. Like any CefWindow it can be framed with
titlebar or frameless, and optionally contain draggable regions (subject to
platform limitations described below). Modal dialogs are shown centered on
the parent window (inside a single display) and always stay on top of the
parent window in z-order. Sizing behavior and available window buttons are
controlled via the usual CefWindowDelegate callbacks. For example, the dialog
can have a preferred size with resize, minimize and maximize disabled (via
GetPreferredSize, CanResize, CanMinimize and CanMaximize respectively).
This change adds support for two modality modes. With window modality all
controls in the parent window are disabled. With browser modality only the
browser view in the parent window is disabled.
Both modality modes require that a valid parent window be returned via
GetParentWindow. For window modality return true from IsWindowModalDialog
and call CefWindow::Show. For browser modality return false from
IsWindowModalDialog (the default value) and call
CefWindow::ShowAsBrowserModalDialog with a reference to the parent window's
browser view.
Window modal dialog behavior depends on the platform. On Windows and
Linux these dialogs have a titlebar and can be moved independent of the
parent window. On macOS these dialogs do not have a titlebar, move with
the parent window, and do not support draggable regions (because they are
implemented using sheets). On Linux disabling the parent window controls
requires a window manager the supports _NET_WM_STATE_MODAL.
Browser modal dialog behavior is similar on all platforms. The dialog will
be automatically sized and positioned relative to the parent window's
browser view. Closing the parent window or navigating the parent browser
view will dismiss the dialog. The dialog can also be moved independent of
the parent window though it will be recentered when the parent window
itself is resized or redisplayed. On MacOS the dialog will move along with
the parent window while on Windows and Linux the parent window can be moved
independently.
To test: Use the Tests > Dialog Window menu option in cefclient with Views
enabled (`--use-views` or `--enable-chrome-runtime` command-line flag).
Browser modal dialog is the default behavior. For window modal dialog add
the `--use-window-modal-dialog` command-line flag.
This change adds a `--use-default-popup` command-line option to cefclient. When
specified, popup windows will be created with default styling (e.g. without an
application-provided native parent window).
This change also adds some reasonable default window bounds in cases where they
are not specified by the client.
- Remove CefRequestContextHandler::OnBeforePluginLoad and
CefRequestContext::PurgePluginListCache (fixes issue #3047). These methods
stopped being relevant after the removal of Flash support in January 2021.
The last remaining PPAPI plugin (PDF viewer) will switch to a non-plugin
implementation in the near future (see https://crbug.com/702993#c58) and
functionality related to plugin filtering has already been removed in
https://crrev.com/343ae351c9.
- Convert scoped_ptr to std::unique_ptr from <memory>
- Convert arraysize to base::size from include/base/cef_cxx17_backports.h
- Convert NULL to nullptr
- Include include/base/cef_callback.h instead of include/base/cef_bind.h
- Implicit conversion of CefRefPtr<T> or scoped_refptr<T> to T* is gone;
use .get() instead
See the issue for additional details.
This change adds a new CefSettings.root_cache_path value that must be either
equal to or a parent directory of all CefSettings.cache_path and
CefRequestContextSettings.cache_path values. The sandbox may block read/write
access from the NetworkService to directories that do not meet this requirement.
To test: Run cefclient with a combination of the following flags:
--cache-path=c:\temp\cache
Cache data should be persisted to the specified directory.
--request-context-per-browser
A separate numbered cache directory should be created underneath the
cache-path directory for each new browser instance.
--enable-network-service --disable-extensions
Same tests, but with NetworkService enabled.
Known issues:
- When NetworkService is enabled a C:\temp\cache\cache\Cache directory is
created (should be C:\temp\cache\Cache).
This change removes cookie and request handler functionality that will not
supported by the NetworkService. Specifically, it is no longer possible to
change cookie storage locations at runime by returning a different
CefCookieManager for an already initialized CefRequestContext. After this change
you will need to use a separate CefRequestContext when creating a CefBrowser if
you require separate cookie storage.
The following methods have been removed:
- CefCookieManager::CreateManager
- CefCookieManager::GetBlockingManager
- CefCookieManager::SetStoragePath
- CefRequestContextHandler::GetCookieManager
The following methods have been renamed:
- CefRequestContext::GetDefaultCookieManager to GetCookieManager.
This change substantially simplifies the network implementation in CEF because
it is no longer necessary to proxy objects that are normally owned by Chromium.
Chromium patches that are no longer necessary will be removed as a follow-up
commit.
To test: Verify that `ceftests --gtest_filter=-PluginTest.*` pass with
NetworkService disabled. Plugin tests will be fixed in a follow-up commit.
- Add CefRequestContext::LoadExtension, CefExtension, CefExtensionHandler and
related methods/interfaces.
- Add chrome://extensions-support that lists supported Chrome APIs.
- Add CefBrowserHost::SetAutoResizeEnabled and CefDisplayHandler::OnAutoResize
to support browser resize based on preferred web contents size.
- views: Add support for custom CefMenuButton popups.
- cefclient: Run with `--load-extension=set_page_color` command-line flag for
an extension loading example. Add `--use-views` on Windows and Linux for an
even better example.
- Move all tests from the top-level directory to tests/.
- Move files shared by cefclient and unittests to tests/shared/.
- Add a fused (single header/source file) version of gtest in
tests/gtest/ with associated CMake configuration.
- Test-only headers are now exposed in include/test/. Unit test
targets must define UNIT_TEST in order to access them.
- Replace usage of USING_CEF_SHARED with WRAPPING_CEF_SHARED for
clarity (only the libcef_dll_wrapper target should define it).
- Remove the RENAME_DIRECTORY CMake macro which is no longer used.
- Remove C++11 usage from unittests sources for compatibility with
the binary distribution configuration.
- Windows: Fix build errors due to chrome_elf.dll and imm32.lib
missing from the CMake configuration.
- Add Views header files in a new include/views directory.
- Add initial top-level window (CefWindow), control (CefBrowserView,
CefLabelButton, CefMenuButton, CefPanel, CefScrollView,
CefTextfield) and layout (CefBoxLayout, CefFlowLayout) support.
See libcef/browser/views/view_impl.h comments for implementation
details.
- Add Views example usage in cefclient and cefsimple and Views unit
tests in cef_unittests. Pass the `--use-views` command-line flag to
cefclient, cefsimple and cef_unittests to run using the Views
framework instead of platform APIs. For cefclient and cefsimple
this will create the browser window and all related functionality
using the Views framework. For cef_unittests this will run all
tests (except OSR tests) in a Views-based browser window. Views-
specific unit tests (`--gtest_filter=Views*`) will be run even if
the the `--use-views` flag is not specified.
- Pass the `--hide-frame` command-line flag to cefclient to demo a
frameless Views-based browser window.
- Pass the `--hide-controls` command-line flag to cefclient to demo a
browser window without top controls. This also works in non-Views
mode.
- Pass the `--enable-high-dpi-support` command-line flag to
cef_unittests on Windows to test high-DPI support on a display
that supports it.
- Add CefImage for reading/writing image file formats.
- Add CefBrowser::DownloadImage() for downloading image URLs as a
CefImage representation. This is primarily for loading favicons.
- Add CefMenuModel::CreateMenuModel() and CefMenuModelDelegate for
creating custom menus. This is primarily for use with
CefMenuButton.
- Add CefBrowser::TryCloseBrowser() helper for closing a browser.
Also improve related documentation in cef_life_span_handler.h.
- Rename cef_page_range_t to cef_range_t. It is now also used by
CefTextfield.
- Remove CefLifeSpanHandler::RunModal() which is never called.
- Add draggable regions example to cefclient.
- Default plugin loading policy can be specified using the new
`--plugin-policy=[allow|block|detect]` command-line flag.
- Move CefRequestHandler::OnBeforePluginLoad to
CefRequestContextHandler and add a new policy argument that
supports different actions (allow, block, detect, disable) on a
per-plugin-instance basis.
- Add CefContextMenuHandler::RunContextMenu for providing a custom
context menu implementation.
- Add CefResourceBundleHandler::GetDataResourceForScale for
returning scaled resources (issue #1272).
- Add CefResourceBundle for retrieving resources from the resource
bundle (*.pak) files loaded by CEF during startup or via the
CefResourceBundleHandler.
- Linux: Fix Debug build IO access warning with CefGetMimeType.
- cef_unittests: Move the refcounting implementation from TestHandler
to subclasses in order to support interface inheritance from
subclasses.
- CefRequestContext instances can be configured using a new CefRequestContextSettings structure passed to CefRequestContext::CreateContext.
- Scheme registration is now per-request-context using new CefRequestContext::RegisterSchemeHandlerFactory and ClearSchemeHandlerFactories methods.
- Cookie managers are now per-request-context by default and can be retrieved using a new CefRequestContext::GetDefaultCookieManager method.
- CefURLRequest::Create now accepts an optional CefRequestContext argument for associating a URL request with a context (browser process only).
- The CefRequestContextHandler associated with a CefRequestContext will not be released until all objects related to that context have been destroyed.
- When the cache path is empty an in-memory cache ("incognito mode") will be used for storage and no data will be persisted to disk.
- Add CefSettings.user_data_path which specifies the location where user data such as spell checking dictionary files will be stored on disk.
- Add asynchronous callbacks for all CefCookieManager methods.
- Add PK_LOCAL_APP_DATA and PK_USER_DATA path keys for retrieving user directories via CefGetPath.
- cefclient: Add "New Window" test that creates a new window unrelated to existing windows. When used in combination with `--request-context-per-browser` the new window will be given a new and isolated request context.
git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@2040 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
- Simplify and document the relationship between the various context object types. See browser_context.h for a description of the new relationships.
- cefclient: Add `request-context-per-browser` command-line flag for testing multiple CefRequestContext instances.
- cefclient: Add a CefURLRequest example.
