This restores the behavior prior to revision 438382c. Calling
InitializeSandboxInfo from inside libcef won’t work unless libcef is
statically linked with the executable, so there's no point in doing so.
See the Chromium sandbox docs for background.
The behavior has changed as follows with NetworkService enabled:
- All pending and in-progress requests will now be aborted when the CEF context
or associated browser is destroyed. The OnResourceLoadComplete callback will
now also be called in this case for in-progress requests that have a handler.
- The CefResourceHandler::Cancel method will now always be called when resource
handling is complete, irrespective of whether handling completed successfully.
- Request callbacks that arrive after the OnBeforeClose callback for the
associated browser (which may happen for in-progress requests that are aborted
on browser destruction) will now always have a non-nullptr CefBrowser
parameter.
- Allow empty parameters to CefRequest and CefResponse methods where it makes
sense (e.g. resetting default response state, or clearing a referrer value).
- Fixed a reference loop that was keeping CefResourceHandler objects from being
destroyed if they were holding a callback reference (from ProcessRequest,
ReadResponse, etc.) during CEF context or associated browser destruction.
- Fixed an issue where the main frame was not detached on browser destruction
which could cause a crash due to RFH use-after-free (see issue #2498).
To test: All unit tests pass as expected.
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).
- 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.
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).
- 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.
- 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.
- Introduce native/ and osr/ folders for native (non-platform-agnostic) and
osr (windowless) code respectively.
- 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.
- Support multiple simultaneous popups (issue #1289).
- 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.
- Windows/Mac: Use `--enable-widevine-cdm` command-line flag to
enable download of CDM binaries via the component updater.
- Linux: Use `--widevide-cdm-path` and `--widevine-cdm-version`
command-line flags to load CDM binaries that already exist on
the system.
- A cache-path value is usually required when CDM is enabled.
- 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.

- 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.
