* This CL add a GetInstance() method to singleton classes instead of relying ↵satish@chromium.org2010-12-041-1/+7
| | | | | | | | | | | | | | | | | on the callers to use Singleton<T>. In some cases I have used the LazyInstance<T> pattern as that was simpler. This is a small step towards making all singleton classes use the Singleton<T> pattern within their code and not expect the callers to know about it. I have selected all files under src/app and src/base which use Singleton<T> in this CL. Once this CL goes in I'll work on the rest of the files. BUG=65298 TEST=all existing tests should continue to pass.

* Integrate ETW with VLOG logging.siggi@chromium.org2010-11-041-1/+13
| | | | | | | | | | | | | This change extends the log severities into the negative for VLOG verbosities. It also keeps track of file/line information and passes it to any registered log handler. The log level is naturally controlled by translating ETW log levels to the severities.

* Integrate the base logging with Event Tracing for Windows. This allows ETW ↵siggi@chromium.org2009-11-251-0/+60
to control the log level and log feature flags from outside the process, and all log messages can be transported into ETW trace sessions.As is this provides an event trace provider class thatmanages the log level on control callbacks and shunts the formatted log messages to ETW when warranted.The provider observes one feature flag, which when turned on causes it to capture and log a stack trace at the log site, which can be helpful when diagnosing errors from logs.This CL also initializes ETW logging for chrome.dll, but only if the environment variable "CHROME_ETW_LOGGING" is set. The ETW machinery may create a thread in every process registering a trace provider, and the environment variable makes this overhead optional.
