The `SugaredLogger` +isn't any harder to use than other logging packages, and the `Logger` makes +structured logging possible in performance-sensitive contexts. Across a fleet +of Go microservices, making each application even slightly more efficient adds +up quickly. + +### Why aren't `Logger` and `SugaredLogger` interfaces? + +Unlike the familiar `io.Writer` and `http.Handler`, `Logger` and +`SugaredLogger` interfaces would include *many* methods. As [Rob Pike points +out][go-proverbs], "The bigger the interface, the weaker the abstraction." +Interfaces are also rigid — *any* change requires releasing a new major +version, since it breaks all third-party implementations. + +Making the `Logger` and `SugaredLogger` concrete types doesn't sacrifice much +abstraction, and it lets us add methods without introducing breaking changes. +Your applications should define and depend upon an interface that includes +just the methods you use. + +### Why sample application logs? + +Applications often experience runs of errors, either because of a bug or +because of a misbehaving user. Logging errors is usually a good idea, but it +can easily make this bad situation worse: not only is your application coping +with a flood of errors, it's also spending extra CPU cycles and I/O logging +those errors. Since writes are typically serialized, logging limits throughput +when you need it most. + +Sampling fixes this problem by dropping repetitive log entries. Under normal +conditions, your application writes out every entry. When similar entries are +logged hundreds or thousands of times each second, though, zap begins dropping +duplicates to preserve throughput. + +### Why do the structured logging APIs take a message in addition to fields? + +Subjectively, we find it helpful to accompany structured context with a brief +description. This isn't critical during development, but it makes debugging +and operating unfamiliar systems much easier. + +More concretely, zap's sampling algorithm uses the message to identify +duplicate entries. In our experience, this is a practical middle ground +between random sampling (which often drops the exact entry that you need while +debugging) and hashing the complete entry (which is prohibitively expensive). + +### Why include package-global loggers? + +Since so many other logging packages include a global logger, many +applications aren't designed to accept loggers as explicit parameters. +Changing function signatures is often a breaking change, so zap includes +global loggers to simplify migration. + +Avoid them where possible. + +### Why include dedicated Panic and Fatal log levels? + +In general, application code should handle errors gracefully instead of using +`panic` or `os.Exit`. However, every rule has exceptions, and it's common to +crash when an error is truly unrecoverable. To avoid losing any information +— especially the reason for the crash — the logger must flush any +buffered entries before the process exits. + +Zap makes this easy by offering `Panic` and `Fatal` logging methods that +automatically flush before exiting. Of course, this doesn't guarantee that +logs will never be lost, but it eliminates a common error. + +See the discussion in uber-go/zap#207 for more details. + +### What's `DPanic`? + +`DPanic` stands for "panic in development." In development, it logs at +`PanicLevel`; otherwise, it logs at `ErrorLevel`. `DPanic` makes it easier to +catch errors that are theoretically possible, but shouldn't actually happen, +*without* crashing in production. + +If you've ever written code like this, you need `DPanic`: + +```go +if err != nil { + panic(fmt.Sprintf("shouldn't ever get here: %v", err)) +} +``` + +## Installation + +### What does the error `expects import "go.uber.org/zap"` mean? + +Either zap was installed incorrectly or you're referencing the wrong package +name in your code. + +Zap's source code happens to be hosted on GitHub, but the [import +path][import-path] is `go.uber.org/zap`. This gives us, the project +maintainers, the freedom to move the source code if necessary. However, it +means that you need to take a little care when installing and using the +package. + +If you follow two simple rules, everything should work: install zap with `go +get -u go.uber.org/zap`, and always import it in your code with `import +"go.uber.org/zap"`. Your code shouldn't contain *any* references to +`github.com/uber-go/zap`. + +## Usage + +### Does zap support log rotation? + +Zap doesn't natively support rotating log files, since we prefer to leave this +to an external program like `logrotate`. + +However, it's easy to integrate a log rotation package like +[`gopkg.in/natefinch/lumberjack.v2`][lumberjack] as a `zapcore.WriteSyncer`. + +```go +// lumberjack.Logger is already safe for concurrent use, so we don't need to +// lock it. +w := zapcore.AddSync(&lumberjack.Logger{ + Filename: "/var/log/myapp/foo.log", + MaxSize: 500, // megabytes + MaxBackups: 3, + MaxAge: 28, // days +}) +core := zapcore.NewCore( + zapcore.NewJSONEncoder(zap.NewProductionEncoderConfig()), + w, + zap.InfoLevel, +) +logger := zap.New(core) +``` + +[go-proverbs]: https://go-proverbs.github.io/ +[import-path]: https://golang.org/cmd/go/#hdr-Remote_import_paths +[lumberjack]: https://godoc.org/gopkg.in/natefinch/lumberjack.v2 diff --git a/vendor/go.uber.org/zap/LICENSE.txt b/vendor/go.uber.org/zap/LICENSE.txt new file mode 100644 index 0000000..6652bed --- /dev/null +++ b/vendor/go.uber.org/zap/LICENSE.txt @@ -0,0 +1,19 @@ +Copyright (c) 2016-2017 Uber Technologies, Inc. + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in +all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

It includes a reflection-free, zero-allocation +JSON encoder, and the base `Logger` strives to avoid serialization overhead +and allocations wherever possible. By building the high-level `SugaredLogger` +on that foundation, zap lets users *choose* when they need to count every +allocation and when they'd prefer a more familiar, loosely typed API. + +As measured by its own [benchmarking suite][], not only is zap more performant +than comparable structured logging packages — it's also faster than the +standard library.
