glog: update glog to the latest internal version (#59) This change upstreams a number of changes since the last package update. In particular this adds: - New exported APIs (see godoc for further details): - glog.VDepth - glog.InfoDepthf - glog.WarningDepthf - glog.ErrorDepthf - glog.FatalDepthf - glog.ExitDepthf - glog.Names - glog.NewStandardLogger - glog.Verbose.InfoDepth - glog.Verbose.InfoDepthf - glog.ErrNoLog - The -log_backtrace_at flag accepts now a comma-separated list of file:line locations. - The -vmodule flag accepts a new syntax to match the full path to a module instead of just the module name. See the updated package documentation. - A new internal/logsink package to support other outputs than files. Note: This package is internal, because we cannot guarantee at this point that the API remains stable. More details at go/log-vs-glog (google-internal).
Leveled execution logs for Go.
This is an efficient pure Go implementation of leveled logs in the manner of the open source C++ package glog.
By binding methods to booleans it is possible to use the log package without paying the expense of evaluating the arguments to the log. Through the -vmodule flag, the package also provides fine-grained control over logging at the file level.
The comment from glog.go introduces the ideas:
Package glog implements logging analogous to the Google-internal C++ INFO/ERROR/V setup. It provides the functions Info, Warning, Error, Fatal, plus formatting variants such as Infof. It also provides V-style loggingcontrolled by the -v and -vmodule=file=2 flags.
Basic examples:
glog.Info("Prepare to repel boarders")
glog.Fatalf("Initialization failed: %s", err)
See the documentation for the V function for an explanation of these examples:
if glog.V(2) {
glog.Info("Starting transaction...")
}
glog.V(2).Infoln("Processed", nItems, "elements")
The repository contains an open source version of the log package used inside Google. The master copy of the source lives inside Google, not here. The code in this repo is for export only and is not itself under development. Feature requests will be ignored.
