// TODO(1151236): Need to update the description, because logging for PA
// standalone library was minimized.
//
// Optional message capabilities
// -----------------------------
// Assertion failed messages and fatal errors are displayed in a dialog box
// before the application exits. However, running this UI creates a message
// loop, which causes application messages to be processed and potentially
// dispatched to existing application windows. Since the application is in a
// bad state when this assertion dialog is displayed, these messages may not
// get processed and hang the dialog, or the application might go crazy.
//
// Therefore, it can be beneficial to display the error dialog in a separate
// process from the main application. When the logging system needs to display
// a fatal error dialog box, it will look for a program called
// "DebugMessage.exe" in the same directory as the application executable. It
// will run this application with the message as the command line, and will
// not include the name of the application as is traditional for easier
// parsing.
//
// The code for DebugMessage.exe is only one line. In WinMain, do:
//   MessageBox(NULL, GetCommandLineW(), L"Fatal Error", 0);
//
// If DebugMessage.exe is not found, the logging code will use a normal
// MessageBox, potentially causing the problems discussed above.

// Instructions
// ------------
//
// Make a bunch of macros for logging.  The way to log things is to stream
// things to PA_LOG(<a particular severity level>).  E.g.,
//
//   PA_LOG(INFO) << "Found " << num_cookies << " cookies";
//
// You can also do conditional logging:
//
//   PA_LOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
//
// The CHECK(condition) macro is active in both debug and release builds and
// effectively performs a PA_LOG(FATAL) which terminates the process and
// generates a crashdump unless a debugger is attached.
//
// There are also "debug mode" logging macros like the ones above:
//
//   PA_DLOG(INFO) << "Found cookies";
//
//   PA_DLOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
//
// All "debug mode" logging is compiled away to nothing for non-debug mode
// compiles.  PA_LOG_IF and development flags also work well together
// because the code can be compiled away sometimes.
//
// We also have
//
//   PA_LOG_ASSERT(assertion);
//   PA_DLOG_ASSERT(assertion);
//
// which is syntactic sugar for PA_{,D}LOG_IF(FATAL, assert fails) << assertion;
//
// There are "verbose level" logging macros.  They look like
//
//   PA_VLOG(1) << "I'm printed when you run the program with --v=1 or more";
//   PA_VLOG(2) << "I'm printed when you run the program with --v=2 or more";
//
// These always log at the INFO log level (when they log at all).
//
// There's also PA_VLOG_IS_ON(n) "verbose level" condition macro. To be used as
//
//   if (PA_VLOG_IS_ON(2)) {
//     // do some logging preparation and logging
//     // that can't be accomplished with just PA_VLOG(2) << ...;
//   }
//
// There is also a PA_VLOG_IF "verbose level" condition macro for sample
// cases, when some extra computation and preparation for logs is not
// needed.
//
//   PA_VLOG_IF(1, (size > 1024))
//      << "I'm printed when size is more than 1024 and when you run the "
//         "program with --v=1 or more";
//
// We also override the standard 'assert' to use 'PA_DLOG_ASSERT'.
//
// Lastly, there is:
//
//   PA_PLOG(ERROR) << "Couldn't do foo";
//   PA_DPLOG(ERROR) << "Couldn't do foo";
//   PA_PLOG_IF(ERROR, cond) << "Couldn't do foo";
//   PA_DPLOG_IF(ERROR, cond) << "Couldn't do foo";
//   PA_PCHECK(condition) << "Couldn't do foo";
//   PA_DPCHECK(condition) << "Couldn't do foo";
//
// which append the last system error to the message in string form (taken from
// GetLastError() on Windows and errno on POSIX).
//
// The supported severity levels for macros that allow you to specify one
// are (in increasing order of severity) INFO, WARNING, ERROR, and FATAL.
//
// Very important: logging a message at the FATAL severity level causes
// the program to terminate (after the message is logged).
//
// There is the special severity of DFATAL, which logs FATAL in DCHECK-enabled
// builds, ERROR in normal mode.
//
// Output is formatted as per the following example:
// [VERBOSE1:drm_device_handle.cc(90)] Succeeded
// authenticating /dev/dri/card0 in 0 ms with 1 attempt(s)
//
// The colon separated fields inside the brackets are as follows:
// 1. The log level
// 2. The filename and line number where the log was instantiated
//
