When the NetworkService is enabled the U-A string is configured via
SystemNetworkContextManager::CreateDefaultNetworkContextParams, which calls
chrome_content_browser_client.cc GetUserAgent(). This change modifies the Chrome
implementation to match CEF, so that the U-A product component can still be
overridden via the `--product-version` command-line flag.
To test: Verify that chrome://version, navigator.userAgent (JS executed from
DevTools console) and network requests (headers shown in DevTools Network tab)
show the expected User-Agent value in the following cases:
- Running `cefclient --enable-network-service --user-agent="<value>"`
- Running `cefclient --enable-network-service --product-version="<value>"`
To test:
- All tests pass with NetworkService disabled. DownloadTest.*, ExtensionTest.*
and PluginTest.* tests pass with NetworkService enabled.
- The PDF extension displays a file, and the download and print buttons work.
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.*
This adds *.pak, locales/*.pak , chrome-sandbox, libGLESv2.so, libEGL.so and
swiftshader/*.so to the list of binaries that will be loaded from the libcef.so
directory instead of the executable directory by default.
- Windows: 10.0.17763.0 SDK is now required.
- Mac: 10.13 SDK is now required.
- Removed CefRequestContext::ResolveHostCached which is no longer supported by Chromium.
- The |category| value for all TRACE calls from CEF client applications is now
"cef.client" due to https://crrev.com/331266377d.
- The |with_menu_marker| parameter to CreateMenuButton has been removed due to
https://crrev.com/7f7e382118.
- Add CefWindowInfo::shared_texture_enabled and
CefRenderHandler::OnAcceleratedPaint for shared texture support. Currently
only supported on Windows (D3D11).
- Add CefWindowInfo::external_begin_frame_enabled and
CefBrowserHost::SendExternalBeginFrame for external begin frame support.
Known issues:
- The CefLoadCRLSetsFile function needs to be re-implemented (see issue #2497).
- Linux: GTK2 support has been removed. The cefclient sample needs to be updated
to use GTK3 (see issue #2014).
- 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.
- Crash reporting is enabled and configured using a "crash_reporter.cfg"
file. See comments in include/cef_crash_util.h and tools/crash_server.py
for usage.
- Don't set InitParams::TRANSLUCENT_WINDOW. Setting this resulted in
the WS_EX_COMPOSITED style being added and the WS_THICKFRAME style
being removed, which disabled Aero Snap.
- Remove the non-client border to get a completely frameless window.
Having a border is problematic because the top is drawn by Windows
while the rest is drawn black. Having Windows draw part of the
border is required to enable the window drop shadow (see
HWNDMessageHandler::SetDwmFrameExtension).
- Delete the remove_caption patches which are no longer required.
- Net security (CT, HSTS) expiration based on build age is now
disabled by default.
- Add new enable_net_security_expiration option to CefSettings and
CefRequestContextSettings.
- Simplify usage of OnBeforePluginLoad (issue #2015)
- Switch crash reporting from crashpad to breakpad on Windows and OS X.
Adds a new chrome_elf.dll dependency on Windows (issue #1995)
- Remove CefTextfield::GetPlaceholderTextColor() method which is no
longer supported by Chromium.
- Remove |accept_lang| parameter from CefJSDialogHandler::OnJSDialog
and CefFormatUrlForSecurityDisplay (see https://crbug.com/336973#c36).
- Remove remaining NPAPI-related code including functions from
cef_web_plugin.h (see https://crbug.com/493212#c55).
- Mac: 10.7+ deployment target is now required for client applications.
- Mac: Remove CefBrowserHost::SetWindowVisibility (issue #1375). No
replacement is required for windowed rendering. Use WasHidden for
off-screen rendering.
- Windows: Visual Studio 2015 Update 2 is now required when building
CEF/Chromium.
- 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.
- Delete include/cef_runnable.h (issue #1336).
- Build the cef_unittests target using all Chromium headers. Add a
USING_CHROMIUM_INCLUDES define and libcef_dll_wrapper_unittests
target to support this. This change avoids compile errors due to
the divergence of CEF and Chromium base/ header implementations.
The libcef_dll_wrapper sources must now compile successfully with
both CEF and Chromium base/ headers (issue #1632).
- The onbeforeunload message specified via JavaScript is no longer
passed to the client (see http://crbug.com/587940).
- Building on Windows now requires the Windows 10.0.10586 SDK.
- Remove CefParseCSSColor which was implemented using Blink code in the
browser process. This is longer advisable now that the Oilpan GC is enabled.
- Avoid potential renderer process crashes by disabling script actions
on the CefV8Context passed to CefRenderProcessHandler::OnContextReleased.
- Improve ordering of CefLoadHandler callbacks. OnLoadingStateChange will
be called before and after all calls to OnLoadStart and OnLoadEnd.
OnLoadStart/OnLoadEnd calls will occur as matching pairs
(see http://crbug.com/539952#c2).
- Remove the |requesting_url| argument to CefGeolocationHandler::
OnCancelGeolocationPermission. Clients can use the |request_id| argument
to track this information themselves.
- Fix a crash when loading the PDF extension in multiple browsers with a
custom CefRequestContext (issue #1757).
- Persist modified user preferences including per-host zoom settings when a
cache_path value is specified and persist_user_preferences is set to true
via CefSettings or CefRequestContextSettings.
- Avoid the need to duplicate files from chrome/ by having CefBrowserContext
extend Chrome's Profile class.
- Implement CefRequestHandler::OnBeforeBrowse using NavigationThrottle
instead of ResourceThrottle (see http://crbug.com/537634). The CefRequest
object passed to OnBeforeBrowse will no longer have an associated request
identifier.
- Mac: Remove additional helper apps which are no longer required (see
http://crbug.com/520680)
- Remove the UR_FLAG_REPORT_RAW_HEADERS flag which is no longer supported (see
http://crbug.com/517114)
- Remove the CefBrowserSettings.java parameter. Java is an NPAPI plugin and
NPAPI plugins are no longer supported (see http://crbug.com/470301#c11)
- Add CefFormatUrlForSecurityDisplay function in cef_parser.h
- Fix crash when passing `--disable-extensions` command-line flag (issue #1721)
- Linux: Fix NSS handler loading (issue #1727)
- Mac: 10.10 SDK is now required for building (see http://crbug.com/463170#c63).
Older SDKs can be used for a short time by setting mac_sdk_min via GYP_DEFINES.
A system-wide installation of the Pepper Flash plugin is available from Adobe
for Windows and Mac OS X platforms as a separate download. To enable automatic
detection and loading of the system-wide installation pass the
`--enable-system-flash` command-line flag.
The Pepper Flash plugin can also be loaded by specifying the file path and
version via the `--ppapi-flash-path=<path> --ppapi-flash-version=<version>`
command-line flags. The version can be identified by viewing the
manifest.json file in the same directory as the Pepper Flash plugin library.
- Add a new CefRequestHandler::OnResourceResponse() method for inspecting the request/response headers and potentially restarting or redirecting the request.
- Add a new CefRequest::GetIdentifier() method for tracking a request across multiple CefRequestHandler callbacks.
- Pass a CefRequest object instead of just the old URL to CefRequestHandler::OnResourceRedirect().
git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@2073 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
- 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
- Always set the browser process VSync rate (frame rate) to CefSettings.windowless_frame_rate.
- When the `enable-begin-frame-scheduling` command-line flag is specified the VSync rate for all processes will be synchronized to CefSettings.windowless_frame_rate. This flag cannot be used in combination with windowed rendering.
- When the `disable-gpu` and `disable-gpu-compositing` command-line flags are specified the CefRenderHandler::OnPaint method will be called directly from the compositor instead of requiring an additional copy for each frame.
- CefRenderHandler::OnPopupSize now passes view coordinates instead of (potentially scaled) pixel coordinates.
- Add OSR unit tests for 2x (HiDPI) pixel scaling.
- Improve CefRenderHandler documentation.
git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@1960 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
This includes:
- Red underline of misspelled words in html text areas.
- Right-click context menu options to correct the misspelled word.
- New CefBrowser::ReplaceMisspelling method for accepting a word replacement.
- Methods added to CefContextMenuParams for retrieving spelling-related information.
- Uses the unified text checker when auto-correct is not enabled to match Google Chrome behavior.
- On Windows and Linux a hunspell dictionary file will be downloaded to the "<cache_path>/Dictionaries" directory as needed, or used from the <cache_path> directory if the file already exists there. The dictionary file will be downloaded from http://cache.pack.google.com/edgedl/chrome/dict/<LANG>-3-0.bdic where <LANG> is the language abbreviation.
- On OS X the spell checking implementation will use the system NSSpellChecker implementation.
The following command-line flags have been added:
--disable-spell-checking => Disable spell-checking support (no red underline, no dictionary file download, etc).
--enable-spelling-auto-correct => Automatically correct common misspellings while typing (like 'omre' to 'more' on Windows/Linux or 'ehlo' to 'helo' on OS X).
--enable-spelling-service => Enable use of the remote Google spelling service (this requires Google API keys).
--override-spell-check-lang=<LANG> => Use the specified dictionary language <LANG> instead of the language specified in the locales.pak file. To see the default/supported dictionary languages: https://code.google.com/p/chromium/codesearch#search/&q=IDS_SPELLCHECK_DICTIONARY%20xtb&sq=package:chromium
git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@1859 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
- Restore CefRenderHandler::OnScrollOffsetChanged.
- Add new RT_PING and RT_SERVICE_WORKER resource type values.
- The resource type for image sub-resource loads has changed from RT_IMAGE to RT_PREFETCH (this is a regression, see http://crbug.com/415253#c23).
- Add a patch to fix a crash in Scheduler::swapQueuesRunPendingTasks* (http://crbug.com/415478).
- Add documentation for cef_key_event_type_t values.
git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@1846 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
This implementation supports both GPU compositing and software compositing (used when GPU is not supported or when passing `--disable-gpu --disable-gpu-compositing` command-line flags). GPU-accelerated features (WebGL and 3D CSS) that did not work with the previous off-screen rendering implementation do work with this implementation when GPU support is available.
Rendering now operates on a per-frame basis. The frame rate is configurable via CefBrowserSettings.windowless_frame_rate up to a maximum of 60fps (potentially limited by how fast the system can generate new frames). CEF generates a bitmap from the compositor backing and passes it to CefRenderHandler::OnPaint.
The previous CefRenderHandler/CefBrowserHost API for off-screen rendering has been restored mostly as-is with some minor changes:
- CefBrowserHost::Invalidate no longer accepts a CefRect region argument. Instead of invalidating a specific region it now triggers generation of a new frame.
- The |dirtyRects| argument to CefRenderHandler::OnPaint will now always be a single CefRect representing the whole view (frame) size. Previously, invalidated regions were listed separately.
- Linux: CefBrowserHost::SendKeyEvent now expects X11 event information instead of GTK event information. See cefclient for an example of converting GTK events to the necessary format.
- Sizes passed to the CefRenderHandler OnPaint and OnPopupSize methods are now already DPI scaled. Previously, the client had to perform DPI scaling.
- Includes drag&drop implementation from issue #1032.
- Includes unit test fixes from issue #1245.
