Marshall Greenblatt 25c75c5fc4 Use new PrintViewManagerBase::PrintToPdf method (fixes issue #3377) 2022-10-14 14:10:30 -04:00
Marshall Greenblatt 4d1fd05740 Update to Chromium version 107.0.5304.0 (#1047731) 2022-09-29 13:09:35 -04:00

Marshall Greenblatt 2ea7459a89 Use Chrome file dialogs on all platforms and runtimes (fixes issue #3314)
All file dialogs irrespective of source, platform and runtime will now be
routed through CefFileDialogManager and trigger CefDialogHandler callbacks
(see issue #3293).

Adds Chrome runtime support for CefBrowserHost::RunFileDialog and
CefDialogHandler callbacks.

Adds Alloy runtime support for internal GTK file and print dialogs on Linux
subject to the following limitations:

1. Internal GTK implementation:
   - Cannot be used with multi-threaded-message-loop because Chromium's
     internal GTK implementation is not thread-safe (does not use GDK threads).
   - Dialogs will not be modal to application windows when used with off-screen
     rendering due to lack of access to the client's top-level GtkWindow.
2. Cefclient CefDialogHandler implementation:
   - Cannot be used with Views because it requires a top-level GtkWindow.

Due to the above limitations no dialog implementation is currently provided for
Views + multi-threaded-message-loop on Linux. In cases where both
implementations are supported the cefclient version is now behind an optional
`--use-client-dialogs` command-line flag.

Expressly forbids multiple simultaneous file dialogs with the internal platform
implementation which uses modal dialogs. CefDialogHandler will still be notified
and can optionally handle each request without a modal dialog (see issue #3154).

Removes some RunFileDialog parameters that are not supported by the Chrome file
dialog implementation (selected_accept_filter parameter, cef_file_dialog_mode_t
overwrite/read-only flags).

Marshall Greenblatt a0a7a35fe2 chrome: Change popup default behavior with native parent (see issue #3294)
When using a Views-hosted browser window the client receives Views-related
callbacks for popups and can thereby customize the Views-hosted popup behavior.
When using an external parent window no Views-related callbacks are delivered
and customization options are restricted to providing a new parent handle via
OnBeforePopup. Consequently, we should default to a normal browser window in
the external parent case instead of the very minimial Views-hosted default.

To test (A):
1. Run `cefclient --use-default-popup --enable-chrome-runtime --use-native`
2. Select Tests > Popup Window
3. Get a normal Chrome browser window

To test (B):
1. Run `cefclient --use-default-popup [--enable-chrome-runtime] [--use-views]`
2. Select Tests > Popup Window
3. Get a native or Views-hosted browser window with title bar only

Marshall Greenblatt 4fbd247231 Add chrome runtime support for more callbacks and ceftests (see issue #2969)
This change adds support for:
- Protocol and request handling.
- Loading and navigation events.
- Display and focus events.
- Mouse/keyboard events.
- Popup browsers.
- Callbacks in the renderer process.
- Misc. functionality required for ceftests.

This change also adds a new CefBrowserProcessHandler::GetCookieableSchemes
callback for configuring global state that will be applied to all
CefCookieManagers by default. This global callback is currently required by the
chrome runtime because the primary ProfileImpl is created via
ChromeBrowserMainParts::PreMainMessageLoopRun (CreatePrimaryProfile) before
OnContextCreated can be called.

ProfileImpl will use the "C:\Users\[user]\AppData\Local\CEF\User Data\Default"
directory by default (on Windows). Cookies may persist in this directory when
running ceftests and may need to be manually deleted if those tests fail.

Remaining work includes:
- Support for client-created request contexts.
- Embedding the browser in a Views hierarchy (cefclient support).
- TryCloseBrowser and DoClose support.
- Most of the CefSettings configuration.
- DevTools protocol and window control (ShowDevTools, ExecuteDevToolsMethod).
- CEF-specific WebUI pages (about, license, webui-hosts).
- Context menu customization (CefContextMenuHandler).
- Auto resize (SetAutoResizeEnabled).
- Zoom settings (SetZoomLevel).
- File dialog runner (RunFileDialog).
- File and JS dialog handlers (CefDialogHandler, CefJSDialogHandler).
- Extension loading (LoadExtension, etc).
- Plugin loading (OnBeforePluginLoad).
- Widevine loading (CefRegisterWidevineCdm).
- PDF and print preview does not display.
- Crash reporting is untested.
- Mac: Web content loads but does not display.

The following ceftests are now passing when run with the
"--enable-chrome-runtime" command-line flag:

Marshall Greenblatt e94a261bf5 Rename CefBrowserHostImpl to AlloyBrowserHostImpl (see issue #2969)
After commit 38d8acfa18 this object is only used with the alloy runtime.
2020-09-22 17:36:06 -04:00
Marshall Greenblatt 38d8acfa18 Create a ChromeBrowserHostImpl for every Chrome tab (see issue #2969)
The Browser object represents the top-level Chrome browser window. One or more
tabs (WebContents) are then owned by the Browser object via TabStripModel. A
new Browser object can be created programmatically using "new Browser" or
Browser::Create, or as a result of user action such as dragging a tab out of an
existing window. New or existing tabs can also be added to an already existing
Browser object.

The Browser object acts as the WebContentsDelegate for all attached tabs. CEF
integration requires WebContentsDelegate callbacks and notification of tab
attach/detach. To support this integration we add a cef::BrowserDelegate
(ChromeBrowserDelegate) member that is created in the Browser constructor and
receives delegation for the Browser callbacks. ChromeBrowserDelegate creates a
new ChromeBrowserHostImpl when a tab is added to a Browser for the first time,
and that ChromeBrowserHostImpl continues to exist until the tab's WebContents
is destroyed. The associated WebContents object does not change, but the
Browser object will change when the tab is dragged between windows.

CEF callback logic is shared between the chrome and alloy runtimes where
possible. This shared logic has been extracted from CefBrowserHostImpl to
create new CefBrowserHostBase and CefBrowserContentsDelegate classes. The
CefBrowserHostImpl class is now only used with the alloy runtime and will be
renamed to AlloyBrowserHostImpl in a future commit.

Marshall Greenblatt 24c2f2fa38 Update to Chromium version 86.0.4240.0 (#800218)
- CefURLRequest::Create is no longer supported in the renderer process
  (see https://crbug.com/891872). Use CefFrame::CreateURLRequest instead.
- Mac platform definitions have been changed from `MACOSX` to `MAC`
  (see https://crbug.com/1105907) and related CMake macro names have
  been updated. The old `OS_MACOSX` define is still set in code and CMake
  for backwards compatibility.
- Linux ARM build is currently broken (see https://crbug.com/1123214).

Marshall Greenblatt e9bf3cdb98 Add initial Chrome runtime support for browser APIs (see issue #2969)
This change adds basic Chrome runtime implementations for CefBrowserContext
and CefBrowserPlatformDelegate. A Chrome browser window with default frame
and styling can now be created using CefBrowserHost::CreateBrowser and some
CefClient callbacks will be triggered via the WebContentsObserver
implementation in CefBrowserHostImpl.

Any additional browser windows created via the Chrome UI will be unmanaged
by CEF. The application message loop will block until all browser windows
have been closed by the user.

Marshall Greenblatt 6cb9f0c695 Move browser runtime-specific logic to CefBrowserPlatformDelegate (see issue #2969)
This change moves the runtime-specific implementations of CefBrowserHostImpl
methods to CefBrowserPlatformDelegate. Some WebContentsDelegate methods
implemented by CefBrowserHostImpl set state or trigger client callbacks.
Those implementations will likely stay with CefBrowserHostImpl and will
need to be called from the Browser equivalents when using the Chrome runtime.

Marshall Greenblatt 8c6cc302d0 Fix OSR surface sizing on browser resize (fixes issue #2733).
This includes the following changes:
- Update usage of surface IDs to match the Aura implementation from the
  RWHVAura/Window classes.
- Batch CefBrowserHost::WasResized calls to avoid excessive/unnecessary calls
  to SynchronizeVisualProperties.
- Cache the results of CefRenderHandler::GetViewRect after resize and make
  RWHVOSR::GetViewBounds the source of truth for all size calculations.
- Fix bounds calculations in CefVideoConsumerOSR with GPU enabled.

Known issues:
- The size passed to OnPaint may be off by 1 pixel in cases where the device
  scale factor is not 1 and does not divide evenly into the pixel size. This is
  due to the inexact conversion from integer pixel size to integer logical size
  for GetViewRect.
2020-02-21 15:02:52 -05:00
Marshall Greenblatt a12c2ab3e1 Add support for MimeHandlerViewInCrossProcessFrame (fixes issue #2727)
The PDF loading documentation in extension_system.cc has be updated to
describe the new code paths.

To support delivery of input events to the mime handler renderer process it is
now necessary to route events via the correct RWHV interface. For Aura-based
platforms (Windows/Linux) this means RWHVAura::On*Event and for macOS this
means RWHVMac::RouteOrProcess*Event. Since Aura uses UI event types these have
become the source of truth on Aura-based platforms with conversion to Web event
types when needed (primarily for OSR).

This change also adds a timeout for CefProcessHostMsg_GetNewBrowserInfo to
avoid a hung renderer process if the guest WebContents route is not
registered via CefMimeHandlerViewGuestDelegate::OnGuestDetached as expected
prior to CefBrowserInfoManager::OnGetNewBrowserInfo being called. This
timeout can be disabled for testing purposes by passing the
`--disable-new-browser-info-timeout` command-line flag.

The `--disable-features=MimeHandlerViewInCrossProcessFrame` command-line
flag can be used for a limited time to restore the previous implementation
based on BrowserPlugin. That implementation will be deleted starting with
the 3897 branch update.

Known issues:
- ExecuteJavaScript calls on the frame hosting the PDF extension will not
  be routed to the mime handler renderer process.
- The PDF extension will not load successfully if blocked by
  ChromePluginPlaceholder and then manually continued via the "Run this
  plugin" context menu option (see https://crbug.com/533069#c41).

Marshall Greenblatt 8f240861e3 Implement NetworkService request interception/handling (see issue #2622).
Implementation notes:
- Chromium change: CookieMonster::SetCookieableSchemes needs to be called
  immediately after the CookieMonster is created in NetworkContext::
  ApplyContextParamsToBuilder. Add a Profile::GetCookieableSchemes method and
  NetworkContextParams.cookieable_schemes member (set from
  ProfileNetworkContextService::CreateNetworkContextParams) to support that.
- Chromium change: Add a ContentBrowserClient::HandleExternalProtocol variant
  that exposes additional NetworkService request information.
- GetResourceResponseFilter is not yet implemented.

API changes:
- Resource-related callbacks have been moved from CefRequestHandler to a new
  CefResourceRequestHandler interface which is returned via the
  GetResourceRequestHandler method. If the CefRequestHandler declines to handle
  a resource it can optionally be handled by the CefRequestContextHandler, if
  any, associated with the loading context.
- The OnProtocolExecution callback has been moved from CefRequestHandler to
  CefResourceRequestHandler and will be called if a custom scheme request is
  unhandled.
- Cookie send/save permission callbacks have been moved from CefRequestHandler
  and CefResourceHandler to CefResourceRequestHandler.
- New methods added to CefResourceHandler that better match NetworkService
  execution sequence expectations. The old methods are now deprecated.
- New methods added to CefRequest and CefResponse.

Known behavior changes with the NetworkService implementation:
- Modifying the |new_url| parameter in OnResourceRedirect will no longer result
  in the method being called an additional time (likely a bug in the old
  implementation).
- Modifying the request URL in OnResourceResponse would previously cause a
  redirect. This behavior is now deprecated because the NetworkService does not
  support this functionality when using default network loaders. Temporary
  support has been added in combination with CefResourceHandler usage only.
- Other changes to the request object in OnResourceResponse will now cause the
  request to be restarted. This means that OnBeforeResourceLoad, etc, will be
  called an additional time with the new request information.
- CefResponse::GetMimeType will now be empty for non-200 responses.
- Requests using custom schemes can now be handled via CefResourceRequestHandler
  with the same callback behavior as builtin schemes.
- Redirects of custom scheme requests will now be followed as expected.
- Default handling of builtin schemes can now be disabled by setting
  |disable_default_handling| to true in GetResourceRequestHandler.
- Unhandled requests (custom scheme or builtin scheme with default handling
  disabled) will fail with an CefResponse::GetError value of
  ERR_UNKNOWN_URL_SCHEME.
- The CefSchemeHandlerFactory::Create callback will now include cookie headers.

To test:
- Run `cefclient --enable-network-service`. All resources should load
  successfully (this tests the transparent proxy capability).
- All tests pass with NetworkService disabled.
- The following tests pass with NetworkService enabled:
  - CookieTest.*
  - FrameTest.* (excluding .*Nav)
  - NavigationTest.* (excluding .Redirect*)
  - RequestHandlerTest.*
  - RequestContextTest.Basic*
  - RequestContextTest.Popup*
  - RequestTest.*
  - ResourceManagerTest.*
  - ResourceRequestHandlerTest.* (excluding .Filter*)
  - SchemeHandlerTest.*
  - StreamResourceHandlerTest.*

2016-04-28 12:57:08 -04:00
Marshall Greenblatt 06e73fff15 Implement Views framework on Windows and Linux (issue #1749).
- 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.

  - Introduce CefBrowserPlatformDelegate for abstracting platform-specific
    implementations of browser host functionality.
  - Move dialog and menu code to separate manager and platform-specific runner
    implementations exposed via CefBrowserPlatformDelegate.
  - Standardize focus-handling behavior between windowed and windowless
    implementations. CefFocusHandler::OnSetFocus() will now also be called for
    osr focus changes.
