# Azure Storage SDK for Go
|
|
||||||
|
|
||||||
The `github.com/Azure/azure-sdk-for-go/storage` package is used to perform operations in Azure Storage Service. To manage your storage accounts (Azure Resource Manager / ARM), use the [github.com/Azure/azure-sdk-for-go/arm/storage](../arm/storage) package. For your classic storage accounts (Azure Service Management / ASM), use [github.com/Azure/azure-sdk-for-go/management/storageservice](../management/storageservice) package.

|
||||||
|
|
||||||
Logrus is a structured logger for Go (golang), completely API compatible with
|
|
||||||
the standard library logger. [Godoc][godoc]. **Please note the Logrus API is not
|
|
||||||
yet stable (pre 1.0). Logrus itself is completely stable and has been used in
|
|
||||||
many large deployments. The core API is unlikely to change much but please
|
|
||||||
version control your Logrus to make sure you aren't fetching latest `master` on
|
|
||||||
every build.**
|
|
||||||
|
|
||||||
Nicely color-coded in development (when a TTY is attached, otherwise just
|
|
||||||
plain text):
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
With `log.Formatter = new(logrus.JSONFormatter)`, for easy parsing by logstash
|
|
||||||
or Splunk:

```
|

With the default `log.Formatter = new(logrus.TextFormatter)` when a TTY is not

attached, the output is compatible with the
|
|
||||||
[logfmt](http://godoc.org/github.com/kr/logfmt) format:
|
|
||||||
|
|

```text

|
|
||||||
exit status 1
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Example
|
|
||||||
|
|
||||||
The simplest way to use Logrus is simply the package-level exported logger:
|
|
||||||
|
|
||||||
```go
|
|
||||||
package main
|
|
||||||
|
|
||||||
import (
|
|
||||||
log "github.com/Sirupsen/logrus"
|
|
||||||
)
|
|
||||||
|
|
||||||
func main() {
|
|
||||||
log.WithFields(log.Fields{
|
|
||||||
"animal": "walrus",
|
|
||||||
}).Info("A walrus appears")
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Note that it's completely api-compatible with the stdlib logger, so you can
|
|
||||||
replace your `log` imports everywhere with `log "github.com/Sirupsen/logrus"`
|
|
||||||
and you'll now have the flexibility of Logrus. You can customize it all you
|
|
||||||
want:
|
|
||||||
|
|
||||||
```go
|
|
||||||
package main
|
|
||||||
|
|
||||||
import (
|
|
||||||
"os"
|
|
||||||
log "github.com/Sirupsen/logrus"
|
|
||||||
"github.com/Sirupsen/logrus/hooks/airbrake"
|
|
||||||
)
|
|
||||||
|
|
||||||
func init() {
|
|
||||||
// Log as JSON instead of the default ASCII formatter.
|
|
||||||
log.SetFormatter(&log.JSONFormatter{})
|
|
||||||
|
|
||||||
// Use the Airbrake hook to report errors that have Error severity or above to
|
|
||||||
// an exception tracker. You can create custom hooks, see the Hooks section.
|
|
||||||
log.AddHook(airbrake.NewHook("https://example.com", "xyz", "development"))
|
|
||||||
|
|
||||||
// Output to stderr instead of stdout, could also be a file.
|
|
||||||
log.SetOutput(os.Stderr)
|
|
||||||
|
|
||||||
// Only log the warning severity or above.
|
|
||||||
log.SetLevel(log.WarnLevel)
|
|
||||||
}
|
|
||||||
|
|
||||||
func main() {
|
|
||||||
log.WithFields(log.Fields{
|
|
||||||
"animal": "walrus",
|
|
||||||
"size": 10,
|
|
||||||
}).Info("A group of walrus emerges from the ocean")
|
|
||||||
|
|
||||||
log.WithFields(log.Fields{
|
|
||||||
"omg": true,
|
|
||||||
"number": 122,
|
|
||||||
}).Warn("The group's number increased tremendously!")
|
|
||||||
|
|
||||||
log.WithFields(log.Fields{
|
|
||||||
"omg": true,
|
|
||||||
"number": 100,
|
|
||||||
}).Fatal("The ice breaks!")
|
|
||||||
|
|
||||||
// A common pattern is to re-use fields between logging statements by re-using
|
|
||||||
// the logrus.Entry returned from WithFields()
|
|
||||||
contextLogger := log.WithFields(log.Fields{
|
|
||||||
"common": "this is a common field",
|
|
||||||
"other": "I also should be logged always",
|
|
||||||
})
|
|
||||||
|
|
||||||
contextLogger.Info("I'll be logged with common and other field")
|
|
||||||
contextLogger.Info("Me too")
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
For more advanced usage such as logging to multiple locations from the same
|
|
||||||
application, you can also create an instance of the `logrus` Logger:
|
|
||||||
|
|
||||||
```go
|
|
||||||
package main
|
|
||||||
|
|
||||||
import (
|
|
||||||
"github.com/Sirupsen/logrus"
|
|
||||||
)
|
|
||||||
|
|
||||||
// Create a new instance of the logger. You can have any number of instances.
|
|
||||||
var log = logrus.New()
|
|
||||||
|
|
||||||
func main() {
|
|
||||||
// The API for setting attributes is a little different than the package level
|
|
||||||
// exported logger. See Godoc.
|
|
||||||
log.Out = os.Stderr
|
|
||||||
|
|
||||||
log.WithFields(logrus.Fields{
|
|
||||||
"animal": "walrus",
|
|
||||||
"size": 10,
|
|
||||||
}).Info("A group of walrus emerges from the ocean")
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Fields
|
|
||||||
|
|
||||||
Logrus encourages careful, structured logging though logging fields instead of
|
|
||||||
long, unparseable error messages. For example, instead of: `log.Fatalf("Failed
|
|
||||||
to send event %s to topic %s with key %d")`, you should log the much more
|
|
||||||
discoverable:
|
|
||||||
|
|
||||||
```go
|
|
||||||
log.WithFields(log.Fields{
|
|
||||||
"event": event,
|
|
||||||
"topic": topic,
|
|
||||||
"key": key,
|
|
||||||
}).Fatal("Failed to send event")
|
|
||||||
```
|
|
||||||
|
|
||||||
We've found this API forces you to think about logging in a way that produces
|
|
||||||
much more useful logging messages. We've been in countless situations where just
|
|
||||||
a single added field to a log statement that was already there would've saved us
|
|
||||||
hours. The `WithFields` call is optional.
|
|
||||||
|
|
||||||
In general, with Logrus using any of the `printf`-family functions should be
|
|
||||||
seen as a hint you should add a field, however, you can still use the
|
|
||||||
`printf`-family functions with Logrus.
|
|
||||||
|
|
||||||
#### Hooks
|
|
||||||
|
|
||||||
You can add hooks for logging levels. For example to send errors to an exception
|
|
||||||
tracking service on `Error`, `Fatal` and `Panic`, info to StatsD or log to
|
|
||||||
multiple places simultaneously, e.g. syslog.
|
|
||||||
|
|
||||||
Logrus comes with [built-in hooks](hooks/). Add those, or your custom hook, in
|
|
||||||
`init`:
|
|
||||||
|
|
||||||
```go
|
|
||||||
import (
|
|
||||||
log "github.com/Sirupsen/logrus"
|
|
||||||
"github.com/Sirupsen/logrus/hooks/airbrake"
|
|
||||||
"github.com/Sirupsen/logrus/hooks/syslog"
|
|
||||||
"log/syslog"
|
|
||||||
)
|
|
||||||
|
|
||||||
func init() {
|
|
||||||
log.AddHook(airbrake.NewHook("https://example.com", "xyz", "development"))
|
|
||||||
|
|
||||||
hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")
|
|
||||||
if err != nil {
|
|
||||||
log.Error("Unable to connect to local syslog daemon")
|
|
||||||
} else {
|
|
||||||
log.AddHook(hook)
|
|
||||||
}
|
|
||||||
}
|
|
||||||
```
|
|

|
|
||||||
|
|
||||||
#### Level logging
|
|
||||||
|
|
||||||
Logrus has six logging levels: Debug, Info, Warning, Error, Fatal and Panic.
|
|
||||||
|
|
||||||
```go
|
|
||||||
log.Debug("Useful debugging information.")
|
|
||||||
log.Info("Something noteworthy happened!")
|
|
||||||
log.Warn("You should probably take a look at this.")
|
|
||||||
log.Error("Something failed but I'm not quitting.")
|
|
||||||
// Calls os.Exit(1) after logging
|
|
||||||
log.Fatal("Bye.")
|
|
||||||
// Calls panic() after logging
|
|
||||||
log.Panic("I'm bailing.")
|
|
||||||
```
|
|
||||||
|
|
||||||
You can set the logging level on a `Logger`, then it will only log entries with
|
|
||||||
that severity or anything above it:
|
|
||||||
|
|
||||||
```go
|
|
||||||
// Will log anything that is info or above (warn, error, fatal, panic). Default.
|
|
||||||
log.SetLevel(log.InfoLevel)
|
|
||||||
```
|
|
||||||
|
|
||||||
It may be useful to set `log.Level = logrus.DebugLevel` in a debug or verbose
|
|
||||||
environment if your application has that.
|
|
||||||
|
|
||||||
#### Entries
|
|
||||||
|
|
||||||
Besides the fields added with `WithField` or `WithFields` some fields are
|
|
||||||
automatically added to all logging events:
|
|
||||||
|
|
||||||
1. `time`. The timestamp when the entry was created.
|
|
||||||
2. `msg`. The logging message passed to `{Info,Warn,Error,Fatal,Panic}` after
|
|
||||||
the `AddFields` call. E.g. `Failed to send event.`
|
|
||||||
3. `level`. The logging level. E.g. `info`.
|
|
||||||
|
|
||||||
#### Environments
|
|
||||||
|
|
||||||
Logrus has no notion of environment.
|
|
||||||
|
|
||||||
If you wish for hooks and formatters to only be used in specific environments,
|
|
||||||
you should handle that yourself. For example, if your application has a global
|
|
||||||
variable `Environment`, which is a string representation of the environment you
|
|
||||||
could do:
|
|
||||||
|
|
||||||
```go
|
|
||||||
import (
|
|
||||||
log "github.com/Sirupsen/logrus"
|
|
||||||
)
|
|
||||||
|
|
||||||
init() {
|
|
||||||
// do something here to set environment depending on an environment variable
|
|
||||||
// or command-line flag
|
|
||||||
if Environment == "production" {
|
|
||||||
log.SetFormatter(logrus.JSONFormatter)
|
|
||||||
} else {
|
|
||||||
// The TextFormatter is default, you don't actually have to do this.
|
|
||||||
log.SetFormatter(logrus.TextFormatter)
|
|
||||||
}
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
This configuration is how `logrus` was intended to be used, but JSON in
|
|
||||||
production is mostly only useful if you do log aggregation with tools like
|
|
||||||
Splunk or Logstash.
|
|
||||||
|
|
||||||
#### Formatters
|
|
||||||
|
|
||||||
The built-in logging formatters are:
|
|
||||||
|
|
||||||
* `logrus.TextFormatter`. Logs the event in colors if stdout is a tty, otherwise
|
|
||||||
without colors.
|
|
||||||
* *Note:* to force colored output when there is no TTY, set the `ForceColors`
|
|
||||||
field to `true`. To force no colored output even if there is a TTY set the
|
|
||||||
`DisableColors` field to `true`
|
|
||||||
* `logrus.JSONFormatter`. Logs fields as JSON.
|
|
||||||
* `logrus_logstash.LogstashFormatter`. Logs fields as Logstash Events (http://logstash.net).
|
|
||||||
|
|
||||||
```go
|
|
||||||
logrus.SetFormatter(&logrus_logstash.LogstashFormatter{Type: “application_name"})
|
|
||||||
```
|
|
||||||
|
|
||||||
Third party logging formatters:
|
|
||||||
|
|
||||||
* [`zalgo`](https://github.com/aybabtme/logzalgo): invoking the P͉̫o̳̼̊w̖͈̰͎e̬͔̭͂r͚̼̹̲ ̫͓͉̳͈ō̠͕͖̚f̝͍̠ ͕̲̞͖͑Z̖̫̤̫ͪa͉̬͈̗l͖͎g̳̥o̰̥̅!̣͔̲̻͊̄ ̙̘̦̹̦.
|
|
||||||
|
|
||||||
You can define your formatter by implementing the `Formatter` interface,
|
|
||||||
requiring a `Format` method. `Format` takes an `*Entry`. `entry.Data` is a
|
|
||||||
`Fields` type (`map[string]interface{}`) with all your fields as well as the
|
|
||||||
default ones (see Entries section above):
|
|
||||||
|
|
||||||
```go
|
|
||||||
type MyJSONFormatter struct {
|
|
||||||
}
|
|
||||||
|
|
||||||
log.SetFormatter(new(MyJSONFormatter))
|
|
||||||
|
|
||||||
func (f *JSONFormatter) Format(entry *Entry) ([]byte, error) {
|
|
||||||
// Note this doesn't include Time, Level and Message which are available on
|
|
||||||
// the Entry. Consult `godoc` on information about those fields or read the
|
|
||||||
// source of the official loggers.
|
|
||||||
serialized, err := json.Marshal(entry.Data)
|
|
||||||
if err != nil {
|
|
||||||
return nil, fmt.Errorf("Failed to marshal fields to JSON, %v", err)
|
|
||||||
}
|
|
||||||
return append(serialized, '\n'), nil
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Logger as an `io.Writer`
|
|
||||||
|
|
||||||
Logrus can be transormed into an `io.Writer`. That writer is the end of an `io.Pipe` and it is your responsibility to close it.
|
|
||||||
|
|
||||||
```go
|
|
||||||
w := logger.Writer()
|
|
||||||
defer w.Close()
|
|
||||||
|
|
||||||
srv := http.Server{
|
|
||||||
// create a stdlib log.Logger that writes to
|
|
||||||
// logrus.Logger.
|
|
||||||
ErrorLog: log.New(w, "", 0),
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Each line written to that writer will be printed the usual way, using formatters
|
|
||||||
and hooks. The level for those entries is `info`.
|
|
||||||
|
|
||||||
#### Rotation
|
|
||||||
|
|
||||||
Log rotation is not provided with Logrus. Log rotation should be done by an
|
|
||||||
external program (like `logrotate(8)`) that can compress and delete old log
|
|
||||||
entries. It should not be a feature of the application-level logger.

designated in writing by the copyright owner as "Not a Contribution."
|
|

|
|
||||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
|
||||||
on behalf of whom a Contribution has been received by Licensor and
|
|
||||||
subsequently incorporated within the Work.
|
|
||||||
|
|
||||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
|
||||||
this License, each Contributor hereby grants to You a perpetual,
|
|
||||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
|
||||||
copyright license to reproduce, prepare Derivative Works of,
|
|
||||||
publicly display, publicly perform, sublicense, and distribute the
|
|
||||||
Work and such Derivative Works in Source or Object form.
|
|
||||||
|
|
||||||
3. Grant of Patent License. Subject to the terms and conditions of
|
|
||||||
this License, each Contributor hereby grants to You a perpetual,
|
|
||||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
|

(except as stated in this section) patent license to make, have made,
|
|

use, offer to sell, sell, import, and otherwise transfer the Work,
|

where such license applies only to those patent claims licensable
|
|
||||||
by such Contributor that are necessarily infringed by their
|
|
||||||
Contribution(s) alone or by combination of their Contribution(s)
|
|
||||||
with the Work to which such Contribution(s) was submitted. If You
|
|
||||||
institute patent litigation against any entity (including a
|
|
||||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
|
||||||
or a Contribution incorporated within the Work constitutes direct
|
|
||||||
or contributory patent infringement, then any patent licenses
|
|
||||||
granted to You under this License for that Work shall terminate
|
|
||||||
as of the date such litigation is filed.
|
|
||||||
|
|
||||||
4. Redistribution. You may reproduce and distribute copies of the
|
|
||||||
Work or Derivative Works thereof in any medium, with or without
|
|
||||||
modifications, and in Source or Object form, provided that You
|
|
||||||
meet the following conditions:
|
|
||||||
|
|
||||||
(a) You must give any other recipients of the Work or
|
|
||||||
Derivative Works a copy of this License; and
|
|
||||||
|
|
||||||
(b) You must cause any modified files to carry prominent notices
|
|
||||||
stating that You changed the files; and
|
|
||||||
|
|
||||||
(c) You must retain, in the Source form of any Derivative Works
|
|
||||||
that You distribute, all copyright, patent, trademark, and
|
|
||||||
attribution notices from the Source form of the Work,
|
|
||||||
excluding those notices that do not pertain to any part of
|
|
||||||
the Derivative Works; and
|
|
||||||
|
|
||||||
(d) If the Work includes a "NOTICE" text file as part of its
|
|
||||||
distribution, then any Derivative Works that You distribute must
|
|
||||||
include a readable copy of the attribution notices contained
|
|
||||||
within such NOTICE file, excluding those notices that do not
|
|
||||||
pertain to any part of the Derivative Works, in at least one
|
|
||||||
of the following places: within a NOTICE text file distributed
|
|
||||||
as part of the Derivative Works; within the Source form or
|
|
||||||
documentation, if provided along with the Derivative Works; or,
|
|
||||||
within a display generated by the Derivative Works, if and
|
|
||||||
wherever such third-party notices normally appear. The contents
|
|
||||||
of the NOTICE file are for informational purposes only and
|
|
||||||
do not modify the License. You may add Your own attribution
|
|
||||||
notices within Derivative Works that You distribute, alongside
|
|
||||||
or as an addendum to the NOTICE text from the Work, provided
|
|
||||||
that such additional attribution notices cannot be construed
|
|
||||||
as modifying the License.
|
|
||||||
|
|
||||||
You may add Your own copyright statement to Your modifications and
|
|
||||||
may provide additional or different license terms and conditions
|
|
||||||
for use, reproduction, or distribution of Your modifications, or
|
|
||||||
for any such Derivative Works as a whole, provided Your use,
|
|
||||||
reproduction, and distribution of the Work otherwise complies with
|
|
||||||
the conditions stated in this License.
|
|
||||||
|
|
||||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
|
||||||
any Contribution intentionally submitted for inclusion in the Work
|
|
||||||
by You to the Licensor shall be under the terms and conditions of
|
|
||||||
this License, without any additional terms or conditions.
|
|
||||||
Notwithstanding the above, nothing herein shall supersede or modify
|
|
||||||
the terms of any separate license agreement you may have executed
|
|
||||||
with Licensor regarding such Contributions.
|
|
||||||
|
|
||||||
6. Trademarks. This License does not grant permission to use the trade
|
|
||||||
names, trademarks, service marks, or product names of the Licensor,
|
|
||||||
except as required for reasonable and customary use in describing the
|
|
||||||
origin of the Work and reproducing the content of the NOTICE file.
|
|
||||||
|
|
||||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
|
||||||
agreed to in writing, Licensor provides the Work (and each
|
|
||||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
|
||||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
|
||||||
implied, including, without limitation, any warranties or conditions
|
|
||||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
|
||||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
|
||||||
appropriateness of using or redistributing the Work and assume any
|
|
||||||
risks associated with Your exercise of permissions under this License.
|
|
||||||
|
|
||||||
8. Limitation of Liability. In no event and under no legal theory,
|
|
||||||
whether in tort (including negligence), contract, or otherwise,
|
|
||||||
unless required by applicable law (such as deliberate and grossly
|
|
||||||
negligent acts) or agreed to in writing, shall any Contributor be
|
|
||||||
liable to You for damages, including any direct, indirect, special,
|
|
||||||
incidental, or consequential damages of any character arising as a
|
|
||||||
result of this License or out of the use or inability to use the
|
|
||||||
Work (including but not limited to damages for loss of goodwill,
|
|
||||||
work stoppage, computer failure or malfunction, or any and all
|
|
||||||
other commercial damages or losses), even if such Contributor
|
|
||||||
has been advised of the possibility of such damages.
|
|
||||||
|
|
||||||
9. Accepting Warranty or Additional Liability. While redistributing
|
|
||||||
the Work or Derivative Works thereof, You may choose to offer,
|
|
||||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
|
||||||
or other liability obligations and/or rights consistent with this
|
|
||||||
License. However, in accepting such obligations, You may act only
|
|
||||||
on Your own behalf and on Your sole responsibility, not on behalf
|
|
||||||
of any other Contributor, and only if You agree to indemnify,
|
|
||||||
defend, and hold each Contributor harmless for any liability
|
|
||||||
incurred by, or claims asserted against, such Contributor by reason
|
|
||||||
of your accepting any such warranty or additional liability.

|
||||||
[简体中文](README_ZH.md)
|
|
||||||
|
|
||||||
## Feature
|
|
||||||
|
|
||||||
- Load multiple data sources(`[]byte` or file) with overwrites.
|
|
||||||
- Read with recursion values.
|
|
||||||
- Read with parent-child sections.
|
|
||||||
- Read with auto-increment key names.
|
|
||||||
- Read with multiple-line values.
|
|
||||||
- Read with tons of helper methods.
|
|
||||||
- Read and convert values to Go types.
|
|
||||||
- Read and **WRITE** comments of sections and keys.
|
|
||||||
- Manipulate sections, keys and comments with ease.
|
|
||||||
- Keep sections and keys in order as you parse and save.
|
|
||||||
|
|
||||||
## Installation
|
|
||||||
|
|
||||||
go get gopkg.in/ini.v1
|
|
||||||
|
|
||||||
## Getting Started
|
|
||||||
|
|
||||||
### Loading from data sources
|
|
||||||
|
|
||||||
A **Data Source** is either raw data in type `[]byte` or a file name with type `string` and you can load **as many as** data sources you want. Passing other types will simply return an error.
|
|
||||||
|
|
||||||
```go
|
|
||||||
cfg, err := ini.Load([]byte("raw data"), "filename")
|
|
||||||
```
|
|
||||||
|
|
||||||
Or start with an empty object:
|
|
||||||
|
|
||||||
```go
|
|
||||||
cfg := ini.Empty()
|
|
||||||
```
|
|
||||||
|
|
||||||
When you cannot decide how many data sources to load at the beginning, you still able to **Append()** them later.
|
|
||||||
|
|
||||||
```go
|
|
||||||
err := cfg.Append("other file", []byte("other raw data"))
|
|
||||||
```
|
|
||||||
|
|
||||||
### Working with sections
|
|
||||||
|
|
||||||
To get a section, you would need to:
|
|
||||||
|
|
||||||
```go
|
|
||||||
section, err := cfg.GetSection("section name")
|
|
||||||
```
|
|
||||||
|
|
||||||
For a shortcut for default section, just give an empty string as name:
|
|
||||||
|
|
||||||
```go
|
|
||||||
section, err := cfg.GetSection("")
|
|
||||||
```
|
|
||||||
|
|
||||||
When you're pretty sure the section exists, following code could make your life easier:
|
|
||||||
|
|
||||||
```go
|
|
||||||
section := cfg.Section("")
|
|
||||||
```
|
|
||||||
|
|
||||||
What happens when the section somehow does not exist? Don't panic, it automatically creates and returns a new section to you.
|
|
||||||
|
|
||||||
To create a new section:
|
|
||||||
|
|
||||||
```go
|
|
||||||
err := cfg.NewSection("new section")
|
|
||||||
```
|
|
||||||
|
|
||||||
To get a list of sections or section names:
|
|
||||||
|
|
||||||
```go
|
|
||||||
sections := cfg.Sections()
|
|
||||||
names := cfg.SectionStrings()
|
|
||||||
```
|
|
||||||
|
|
||||||
### Working with keys
|
|
||||||
|
|
||||||
To get a key under a section:
|
|
||||||
|
|
||||||
```go
|
|
||||||
key, err := cfg.Section("").GetKey("key name")
|
|
||||||
```
|
|
||||||
|
|
||||||
Same rule applies to key operations:
|
|
||||||
|
|
||||||
```go
|
|
||||||
key := cfg.Section("").Key("key name")
|
|
||||||
```
|
|
||||||
|
|
||||||
To create a new key:
|
|
||||||
|
|
||||||
```go
|
|
||||||
err := cfg.Section("").NewKey("name", "value")
|
|
||||||
```
|
|
||||||
|
|
||||||
To get a list of keys or key names:
|
|
||||||
|
|
||||||
```go
|
|
||||||
keys := cfg.Section("").Keys()
|
|
||||||
names := cfg.Section("").KeyStrings()
|
|
||||||
```
|
|
||||||
|
|
||||||
To get a clone hash of keys and corresponding values:
|
|
||||||
|
|
||||||
```go
|
|
||||||
hash := cfg.GetSection("").KeysHash()
|
|
||||||
```
|
|
||||||
|
|
||||||
### Working with values
|
|
||||||
|
|
||||||
To get a string value:
|
|
||||||
|
|
||||||
```go
|
|
||||||
val := cfg.Section("").Key("key name").String()
|
|
||||||
```
|
|
||||||
|
|
||||||
To validate key value on the fly:
|
|
||||||
|
|
||||||
```go
|
|
||||||
val := cfg.Section("").Key("key name").Validate(func(in string) string {
|
|
||||||
if len(in) == 0 {
|
|
||||||
return "default"
|
|
||||||
}
|
|
||||||
return in
|
|
||||||
})
|
|
||||||
```
|
|
||||||
|
|
||||||
To get value with types:
|
|
||||||
|
|
||||||
```go
|
|
||||||
// For boolean values:
|
|
||||||
// true when value is: 1, t, T, TRUE, true, True, YES, yes, Yes, ON, on, On
|
|
||||||
// false when value is: 0, f, F, FALSE, false, False, NO, no, No, OFF, off, Off
|
|
||||||
v, err = cfg.Section("").Key("BOOL").Bool()
|
|
||||||
v, err = cfg.Section("").Key("FLOAT64").Float64()
|
|
||||||
v, err = cfg.Section("").Key("INT").Int()
|
|
||||||
v, err = cfg.Section("").Key("INT64").Int64()
|
|
||||||
v, err = cfg.Section("").Key("UINT").Uint()
|
|
||||||
v, err = cfg.Section("").Key("UINT64").Uint64()
|
|
||||||
v, err = cfg.Section("").Key("TIME").TimeFormat(time.RFC3339)
|
|
||||||
v, err = cfg.Section("").Key("TIME").Time() // RFC3339
|
|
||||||
|
|
||||||
v = cfg.Section("").Key("BOOL").MustBool()
|
|
||||||
v = cfg.Section("").Key("FLOAT64").MustFloat64()
|
|
||||||
v = cfg.Section("").Key("INT").MustInt()
|
|
||||||
v = cfg.Section("").Key("INT64").MustInt64()
|
|
||||||
v = cfg.Section("").Key("UINT").MustUint()
|
|
||||||
v = cfg.Section("").Key("UINT64").MustUint64()
|
|
||||||
v = cfg.Section("").Key("TIME").MustTimeFormat(time.RFC3339)
|
|
||||||
v = cfg.Section("").Key("TIME").MustTime() // RFC3339
|
|
||||||
|
|
||||||
// Methods start with Must also accept one argument for default value
|
|
||||||
// when key not found or fail to parse value to given type.
|
|
||||||
// Except method MustString, which you have to pass a default value.
|
|
||||||
|
|
||||||
v = cfg.Section("").Key("String").MustString("default")
|
|
||||||
v = cfg.Section("").Key("BOOL").MustBool(true)
|
|
||||||
v = cfg.Section("").Key("FLOAT64").MustFloat64(1.25)
|
|
||||||
v = cfg.Section("").Key("INT").MustInt(10)
|
|
||||||
v = cfg.Section("").Key("INT64").MustInt64(99)
|
|
||||||
v = cfg.Section("").Key("UINT").MustUint(3)
|
|
||||||
v = cfg.Section("").Key("UINT64").MustUint64(6)
|
|
||||||
v = cfg.Section("").Key("TIME").MustTimeFormat(time.RFC3339, time.Now())
|
|
||||||
v = cfg.Section("").Key("TIME").MustTime(time.Now()) // RFC3339
|
|
||||||
```
|
|
||||||
|
|
||||||
What if my value is three-line long?
|
|
||||||
|
|
||||||
```ini
|
|
||||||
[advance]
|
|
||||||
ADDRESS = """404 road,
|
|
||||||
NotFound, State, 5000
|
|
||||||
Earth"""
|
|
||||||
```
|
|
||||||
|
|
||||||
Not a problem!
|
|
||||||
|
|
||||||
```go
|
|
||||||
cfg.Section("advance").Key("ADDRESS").String()
|
|
||||||
|
|
||||||
/* --- start ---
|
|
||||||
404 road,
|
|
||||||
NotFound, State, 5000
|
|
||||||
Earth
|
|
||||||
------ end --- */
|
|
||||||
```
|
|
||||||
|
|
||||||
That's cool, how about continuation lines?
|
|
||||||
|
|
||||||
```ini
|
|
||||||
[advance]
|
|
||||||
two_lines = how about \
|
|
||||||
continuation lines?
|
|
||||||
lots_of_lines = 1 \
|
|
||||||
2 \
|
|
||||||
3 \
|
|
||||||
4
|
|
||||||
```
|
|
||||||
|
|
||||||
Piece of cake!
|
|
||||||
|
|
||||||
```go
|
|
||||||
cfg.Section("advance").Key("two_lines").String() // how about continuation lines?
|
|
||||||
cfg.Section("advance").Key("lots_of_lines").String() // 1 2 3 4
|
|
||||||
```
|
|
||||||
|
|
||||||
Note that single quotes around values will be stripped:
|
|
||||||
|
|
||||||
```ini
|
|
||||||
foo = "some value" // foo: some value
|
|
||||||
bar = 'some value' // bar: some value
|
|
||||||
```
|
|
||||||
|
|
||||||
That's all? Hmm, no.
|
|
||||||
|
|
||||||
#### Helper methods of working with values
|
|
||||||
|
|
||||||
To get value with given candidates:
|
|
||||||
|
|
||||||
```go
|
|
||||||
v = cfg.Section("").Key("STRING").In("default", []string{"str", "arr", "types"})
|
|
||||||
v = cfg.Section("").Key("FLOAT64").InFloat64(1.1, []float64{1.25, 2.5, 3.75})
|
|
||||||
v = cfg.Section("").Key("INT").InInt(5, []int{10, 20, 30})
|
|
||||||
v = cfg.Section("").Key("INT64").InInt64(10, []int64{10, 20, 30})
|
|
||||||
v = cfg.Section("").Key("UINT").InUint(4, []int{3, 6, 9})
|
|
||||||
v = cfg.Section("").Key("UINT64").InUint64(8, []int64{3, 6, 9})
|
|
||||||
v = cfg.Section("").Key("TIME").InTimeFormat(time.RFC3339, time.Now(), []time.Time{time1, time2, time3})
|
|
||||||
v = cfg.Section("").Key("TIME").InTime(time.Now(), []time.Time{time1, time2, time3}) // RFC3339
|
|
||||||
```
|
|
||||||
|
|
||||||
Default value will be presented if value of key is not in candidates you given, and default value does not need be one of candidates.
|
|
||||||
|
|
||||||
To validate value in a given range:
|
|
||||||
|
|
||||||
```go
|
|
||||||
vals = cfg.Section("").Key("FLOAT64").RangeFloat64(0.0, 1.1, 2.2)
|
|
||||||
vals = cfg.Section("").Key("INT").RangeInt(0, 10, 20)
|
|
||||||
vals = cfg.Section("").Key("INT64").RangeInt64(0, 10, 20)
|
|
||||||
vals = cfg.Section("").Key("UINT").RangeUint(0, 3, 9)
|
|
||||||
vals = cfg.Section("").Key("UINT64").RangeUint64(0, 3, 9)
|
|
||||||
vals = cfg.Section("").Key("TIME").RangeTimeFormat(time.RFC3339, time.Now(), minTime, maxTime)
|
|
||||||
vals = cfg.Section("").Key("TIME").RangeTime(time.Now(), minTime, maxTime) // RFC3339
|
|
||||||
```
|
|
||||||
|
|
||||||
To auto-split value into slice:
|
|
||||||
|
|
||||||
```go
|
|
||||||
vals = cfg.Section("").Key("STRINGS").Strings(",")
|
|
||||||
vals = cfg.Section("").Key("FLOAT64S").Float64s(",")
|
|
||||||
vals = cfg.Section("").Key("INTS").Ints(",")
|
|
||||||
vals = cfg.Section("").Key("INT64S").Int64s(",")
|
|
||||||
vals = cfg.Section("").Key("UINTS").Uints(",")
|
|
||||||
vals = cfg.Section("").Key("UINT64S").Uint64s(",")
|
|
||||||
vals = cfg.Section("").Key("TIMES").Times(",")
|
|
||||||
```
|
|
||||||
|
|
||||||
### Save your configuration
|
|
||||||
|
|
||||||
Finally, it's time to save your configuration to somewhere.
|
|
||||||
|
|
||||||
A typical way to save configuration is writing it to a file:
|
|
||||||
|
|
||||||
```go
|
|
||||||
// ...
|
|
||||||
err = cfg.SaveTo("my.ini")
|
|
||||||
err = cfg.SaveToIndent("my.ini", "\t")
|
|
||||||
```
|
|
||||||
|
|
||||||
Another way to save is writing to a `io.Writer` interface:
|
|
||||||
|
|
||||||
```go
|
|
||||||
// ...
|
|
||||||
cfg.WriteTo(writer)
|
|
||||||
cfg.WriteToIndent(writer, "\t")
|
|
||||||
```
|
|
||||||
|
|
||||||
## Advanced Usage
|
|
||||||
|
|
||||||
### Recursive Values
|
|
||||||
|
|
||||||
For all value of keys, there is a special syntax `%(<name>)s`, where `<name>` is the key name in same section or default section, and `%(<name>)s` will be replaced by corresponding value(empty string if key not found). You can use this syntax at most 99 level of recursions.
|
|
||||||
|
|
||||||
```ini
|
|
||||||
NAME = ini
|
|
||||||
|
|
||||||
[author]
|
|
||||||
NAME = Unknwon
|
|
||||||
GITHUB = https://github.com/%(NAME)s
|
|
||||||
|
|
||||||
[package]
|
|
||||||
FULL_NAME = github.com/go-ini/%(NAME)s
|
|
||||||
```
|
|
||||||
|
|
||||||
```go
|
|
||||||
cfg.Section("author").Key("GITHUB").String() // https://github.com/Unknwon
|
|
||||||
cfg.Section("package").Key("FULL_NAME").String() // github.com/go-ini/ini
|
|
||||||
```
|
|
||||||
|
|
||||||
### Parent-child Sections
|
|
||||||
|
|
||||||
You can use `.` in section name to indicate parent-child relationship between two or more sections. If the key not found in the child section, library will try again on its parent section until there is no parent section.
|
|
||||||
|
|
||||||
```ini
|
|
||||||
NAME = ini
|
|
||||||
VERSION = v1
|
|
||||||
IMPORT_PATH = gopkg.in/%(NAME)s.%(VERSION)s
|
|
||||||
|
|
||||||
[package]
|
|
||||||
CLONE_URL = https://%(IMPORT_PATH)s
|
|
||||||
|
|
||||||
[package.sub]
|
|
||||||
```
|
|
||||||
|
|
||||||
```go
|
|
||||||
cfg.Section("package.sub").Key("CLONE_URL").String() // https://gopkg.in/ini.v1
|
|
||||||
```
|
|
||||||
|
|
||||||
### Auto-increment Key Names
|
|
||||||
|
|
||||||
If key name is `-` in data source, then it would be seen as special syntax for auto-increment key name start from 1, and every section is independent on counter.
|
|
||||||
|
|
||||||
```ini
|
|
||||||
[features]
|
|
||||||
-: Support read/write comments of keys and sections
|
|
||||||
-: Support auto-increment of key names
|
|
||||||
-: Support load multiple files to overwrite key values
|
|
||||||
```
|
|
||||||
|
|
||||||
```go
|
|
||||||
cfg.Section("features").KeyStrings() // []{"#1", "#2", "#3"}
|
|
||||||
```
|
|
||||||
|
|
||||||
### Map To Struct
|
|
||||||
|
|
||||||
Want more objective way to play with INI? Cool.
|
|
||||||
|
|
||||||
```ini
|
|
||||||
Name = Unknwon
|
|
||||||
age = 21
|
|
||||||
Male = true
|
|
||||||
Born = 1993-01-01T20:17:05Z
|
|
||||||
|
|
||||||
[Note]
|
|
||||||
Content = Hi is a good man!
|
|
||||||
Cities = HangZhou, Boston
|
|
||||||
```
|
|
||||||
|
|
||||||
```go
|
|
||||||
type Note struct {
|
|
||||||
Content string
|
|
||||||
Cities []string
|
|
||||||
}
|
|
||||||
|
|
||||||
type Person struct {
|
|
||||||
Name string
|
|
||||||
Age int `ini:"age"`
|
|
||||||
Male bool
|
|
||||||
Born time.Time
|
|
||||||
Note
|
|
||||||
Created time.Time `ini:"-"`
|
|
||||||
}
|
|
||||||
|
|
||||||
func main() {
|
|
||||||
cfg, err := ini.Load("path/to/ini")
|
|
||||||
// ...
|
|
||||||
p := new(Person)
|
|
||||||
err = cfg.MapTo(p)
|
|
||||||
// ...
|
|
||||||
|
|
||||||
// Things can be simpler.
|
|
||||||
err = ini.MapTo(p, "path/to/ini")
|
|
||||||
// ...
|
|
||||||
|
|
||||||
// Just map a section? Fine.
|
|
||||||
n := new(Note)
|
|
||||||
err = cfg.Section("Note").MapTo(n)
|
|
||||||
// ...
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Can I have default value for field? Absolutely.
|
|
||||||
|
|
||||||
Assign it before you map to struct. It will keep the value as it is if the key is not presented or got wrong type.
|
|
||||||
|
|
||||||
```go
|
|
||||||
// ...
|
|
||||||
p := &Person{
|
|
||||||
Name: "Joe",
|
|
||||||
}
|
|
||||||
// ...
|
|
||||||
```
|
|
||||||
|
|
||||||
It's really cool, but what's the point if you can't give me my file back from struct?
|
|
||||||
|
|
||||||
### Reflect From Struct
|
|
||||||
|
|
||||||
Why not?
|
|
||||||
|
|
||||||
```go
|
|
||||||
type Embeded struct {
|
|
||||||
Dates []time.Time `delim:"|"`
|
|
||||||
Places []string
|
|
||||||
None []int
|
|
||||||
}
|
|
||||||
|
|
||||||
type Author struct {
|
|
||||||
Name string `ini:"NAME"`
|
|
||||||
Male bool
|
|
||||||
Age int
|
|
||||||
GPA float64
|
|
||||||
NeverMind string `ini:"-"`
|
|
||||||
*Embeded
|
|
||||||
}
|
|
||||||
|
|
||||||
func main() {
|
|
||||||
a := &Author{"Unknwon", true, 21, 2.8, "",
|
|
||||||
&Embeded{
|
|
||||||
[]time.Time{time.Now(), time.Now()},
|
|
||||||
[]string{"HangZhou", "Boston"},
|
|
||||||
[]int{},
|
|
||||||
}}
|
|
||||||
cfg := ini.Empty()
|
|
||||||
err = ini.ReflectFrom(cfg, a)
|
|
||||||
// ...
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
So, what do I get?
|
|
||||||
|
|
||||||
```ini
|
|
||||||
NAME = Unknwon
|
|
||||||
Male = true
|
|
||||||
Age = 21
|
|
||||||
GPA = 2.8
|
|
||||||
|
|
||||||
[Embeded]
|
|
||||||
Dates = 2015-08-07T22:14:22+08:00|2015-08-07T22:14:22+08:00
|
|
||||||
Places = HangZhou,Boston
|
|
||||||
None =
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Name Mapper
|
|
||||||
|
|
||||||
To save your time and make your code cleaner, this library supports [`NameMapper`](https://gowalker.org/gopkg.in/ini.v1#NameMapper) between struct field and actual section and key name.
|
|
||||||
|
|
||||||
There are 2 built-in name mappers:
|
|
||||||
|
|
||||||
- `AllCapsUnderscore`: it converts to format `ALL_CAPS_UNDERSCORE` then match section or key.
|
|
||||||
- `TitleUnderscore`: it converts to format `title_underscore` then match section or key.
|
|
||||||
|
|
||||||
To use them:
|
|
||||||
|
|
||||||
```go
|
|
||||||
type Info struct {
|
|
||||||
PackageName string
|
|
||||||
}
|
|
||||||
|
|
||||||
func main() {
|
|
||||||
err = ini.MapToWithMapper(&Info{}, ini.TitleUnderscore, []byte("packag_name=ini"))
|
|
||||||
// ...
|
|
||||||
|
|
||||||
cfg, err := ini.Load([]byte("PACKAGE_NAME=ini"))
|
|
||||||
// ...
|
|
||||||
info := new(Info)
|
|
||||||
cfg.NameMapper = ini.AllCapsUnderscore
|
|
||||||
err = cfg.MapTo(info)
|
|
||||||
// ...
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Same rules of name mapper apply to `ini.ReflectFromWithMapper` function.
|
|
||||||
|
|
||||||
#### Other Notes On Map/Reflect
|
|
||||||
|
|
||||||
Any embedded struct is treated as a section by default, and there is no automatic parent-child relations in map/reflect feature:
|
|
||||||
|
|
||||||
```go
|
|
||||||
type Child struct {
|
|
||||||
Age string
|
|
||||||
}
|
|
||||||
|
|
||||||
type Parent struct {
|
|
||||||
Name string
|
|
||||||
Child
|
|
||||||
}
|
|
||||||
|
|
||||||
type Config struct {
|
|
||||||
City string
|
|
||||||
Parent
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Example configuration:
|
|
||||||
|
|
||||||
```ini
|
|
||||||
City = Boston
|
|
||||||
|
|
||||||
[Parent]
|
|
||||||
Name = Unknwon
|
|
||||||
|
|
||||||
[Child]
|
|
||||||
Age = 21
|
|
||||||
```
|
|
||||||
|
|
||||||
What if, yes, I'm paranoid, I want embedded struct to be in the same section. Well, all roads lead to Rome.
|
|
||||||
|
|
||||||
```go
|
|
||||||
type Child struct {
|
|
||||||
Age string
|
|
||||||
}
|
|
||||||
|
|
||||||
type Parent struct {
|
|
||||||
Name string
|
|
||||||
Child `ini:"Parent"`
|
|
||||||
}
|
|
||||||
|
|
||||||
type Config struct {
|
|
||||||
City string
|
|
||||||
Parent
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Example configuration:
|
|
||||||
|
|
||||||
```ini
|
|
||||||
City = Boston
|
|
||||||
|
|
||||||
[Parent]
|
|
||||||
Name = Unknwon
|
|
||||||
Age = 21
|
|
||||||
```

## FAQs
|
|
||||||
|
|
||||||
### What does `BlockMode` field do?
|
|
||||||
|
|
||||||
By default, library lets you read and write values so we need a locker to make sure your data is safe. But in cases that you are very sure about only reading data through the library, you can set `cfg.BlockMode = false` to speed up read operations about **50-70%** faster.
|
|
||||||
|
|
||||||
### Why another INI library?
|
|
||||||
|
|
||||||
Many people are using my another INI library [goconfig](https://github.com/Unknwon/goconfig), so the reason for this one is I would like to make more Go style code. Also when you set `cfg.BlockMode = false`, this one is about **10-30%** faster.
|
|
||||||
|
|
||||||
To make those changes I have to confirm API broken, so it's safer to keep it in another place and start using `gopkg.in` to version my package at this time.(PS: shorter import path)

## 下载安装
|
|
||||||
|
|
||||||
go get gopkg.in/ini.v1
|
|
||||||
|
|
||||||
## 开始使用
|
|
||||||
|
|
||||||
### 从数据源加载
|
|
||||||
|
|
||||||
一个 **数据源** 可以是 `[]byte` 类型的原始数据，或 `string` 类型的文件路径。您可以加载 **任意多个** 数据源。如果您传递其它类型的数据源，则会直接返回错误。
|
|
||||||
|
|
||||||
```go
|
|
||||||
cfg, err := ini.Load([]byte("raw data"), "filename")
|
|
||||||
```
|
|
||||||
|
|
||||||
或者从一个空白的文件开始：
|
|
||||||
|
|
||||||
```go
|
|
||||||
cfg := ini.Empty()
|
|
||||||
```
|
|
||||||
|
|
||||||
当您在一开始无法决定需要加载哪些数据源时，仍可以使用 **Append()** 在需要的时候加载它们。
|
|
||||||
|
|
||||||
```go
|
|
||||||
err := cfg.Append("other file", []byte("other raw data"))
|
|
||||||
```
|
|
||||||
|
|
||||||
### 操作分区（Section）
|
|
||||||
|
|
||||||
获取指定分区：
|
|
||||||
|
|
||||||
```go
|
|
||||||
section, err := cfg.GetSection("section name")
|
|
||||||
```
|
|
||||||
|
|
||||||
如果您想要获取默认分区，则可以用空字符串代替分区名：
|
|
||||||
|
|
||||||
```go
|
|
||||||
section, err := cfg.GetSection("")
|
|
||||||
```
|
|
||||||
|
|
||||||
当您非常确定某个分区是存在的，可以使用以下简便方法：
|
|
||||||
|
|
||||||
```go
|
|
||||||
section := cfg.Section("")
|
|
||||||
```
|
|
||||||
|
|
||||||
如果不小心判断错了，要获取的分区其实是不存在的，那会发生什么呢？没事的，它会自动创建并返回一个对应的分区对象给您。
|
|
||||||
|
|
||||||
创建一个分区：
|
|
||||||
|
|
||||||
```go
|
|
||||||
err := cfg.NewSection("new section")
|
|
||||||
```
|
|
||||||
|
|
||||||
获取所有分区对象或名称：
|
|
||||||
|
|
||||||
```go
|
|
||||||
sections := cfg.Sections()
|
|
||||||
names := cfg.SectionStrings()
|
|
||||||
```
|
|
||||||
|
|
||||||
### 操作键（Key）
|
|
||||||
|
|
||||||
获取某个分区下的键：
|
|
||||||
|
|
||||||
```go
|
|
||||||
key, err := cfg.Section("").GetKey("key name")
|
|
||||||
```
|
|
||||||
|
|
||||||
和分区一样，您也可以直接获取键而忽略错误处理：
|
|
||||||
|
|
||||||
```go
|
|
||||||
key := cfg.Section("").Key("key name")
|
|
||||||
```
|
|
||||||
|
|
||||||
创建一个新的键：
|
|
||||||
|
|
||||||
```go
|
|
||||||
err := cfg.Section("").NewKey("name", "value")
|
|
||||||
```
|
|
||||||
|
|
||||||
获取分区下的所有键或键名：
|
|
||||||
|
|
||||||
```go
|
|
||||||
keys := cfg.Section("").Keys()
|
|
||||||
names := cfg.Section("").KeyStrings()
|
|
||||||
```
|
|
||||||
|
|
||||||
获取分区下的所有键值对的克隆：
|
|
||||||
|
|
||||||
```go
|
|
||||||
hash := cfg.GetSection("").KeysHash()
|
|
||||||
```
|
|
||||||
|
|
||||||
### 操作键值（Value）
|
|
||||||
|
|
||||||
获取一个类型为字符串（string）的值：
|
|
||||||
|
|
||||||
```go
|
|
||||||
val := cfg.Section("").Key("key name").String()
|
|
||||||
```
|
|
||||||
|
|
||||||
获取值的同时通过自定义函数进行处理验证：
|
|
||||||
|
|
||||||
```go
|
|
||||||
val := cfg.Section("").Key("key name").Validate(func(in string) string {
|
|
||||||
if len(in) == 0 {
|
|
||||||
return "default"
|
|
||||||
}
|
|
||||||
return in
|
|
||||||
})
|
|
||||||
```
|
|
||||||
|
|
||||||
获取其它类型的值：
|
|
||||||
|
|
||||||
```go
|
|
||||||
// 布尔值的规则：
|
|
||||||
// true 当值为：1, t, T, TRUE, true, True, YES, yes, Yes, ON, on, On
|
|
||||||
// false 当值为：0, f, F, FALSE, false, False, NO, no, No, OFF, off, Off
|
|
||||||
v, err = cfg.Section("").Key("BOOL").Bool()
|
|
||||||
v, err = cfg.Section("").Key("FLOAT64").Float64()
|
|
||||||
v, err = cfg.Section("").Key("INT").Int()
|
|
||||||
v, err = cfg.Section("").Key("INT64").Int64()
|
|
||||||
v, err = cfg.Section("").Key("UINT").Uint()
|
|
||||||
v, err = cfg.Section("").Key("UINT64").Uint64()
|
|
||||||
v, err = cfg.Section("").Key("TIME").TimeFormat(time.RFC3339)
|
|
||||||
v, err = cfg.Section("").Key("TIME").Time() // RFC3339
|
|
||||||
|
|
||||||
v = cfg.Section("").Key("BOOL").MustBool()
|
|
||||||
v = cfg.Section("").Key("FLOAT64").MustFloat64()
|
|
||||||
v = cfg.Section("").Key("INT").MustInt()
|
|
||||||
v = cfg.Section("").Key("INT64").MustInt64()
|
|
||||||
v = cfg.Section("").Key("UINT").MustUint()
|
|
||||||
v = cfg.Section("").Key("UINT64").MustUint64()
|
|
||||||
v = cfg.Section("").Key("TIME").MustTimeFormat(time.RFC3339)
|
|
||||||
v = cfg.Section("").Key("TIME").MustTime() // RFC3339
|
|
||||||
|
|
||||||
// 由 Must 开头的方法名允许接收一个相同类型的参数来作为默认值，
|
|
||||||
// 当键不存在或者转换失败时，则会直接返回该默认值。
|
|
||||||
// 但是，MustString 方法必须传递一个默认值。
|
|
||||||
|
|
||||||
v = cfg.Seciont("").Key("String").MustString("default")
|
|
||||||
v = cfg.Section("").Key("BOOL").MustBool(true)
|
|
||||||
v = cfg.Section("").Key("FLOAT64").MustFloat64(1.25)
|
|
||||||
v = cfg.Section("").Key("INT").MustInt(10)
|
|
||||||
v = cfg.Section("").Key("INT64").MustInt64(99)
|
|
||||||
v = cfg.Section("").Key("UINT").MustUint(3)
|
|
||||||
v = cfg.Section("").Key("UINT64").MustUint64(6)
|
|
||||||
v = cfg.Section("").Key("TIME").MustTimeFormat(time.RFC3339, time.Now())
|
|
||||||
v = cfg.Section("").Key("TIME").MustTime(time.Now()) // RFC3339
|
|
||||||
```
|
|
||||||
|
|
||||||
如果我的值有好多行怎么办？
|
|
||||||
|
|
||||||
```ini
|
|
||||||
[advance]
|
|
||||||
ADDRESS = """404 road,
|
|
||||||
NotFound, State, 5000
|
|
||||||
Earth"""
|
|
||||||
```
|
|
||||||
|
|
||||||
嗯哼？小 case！
|
|
||||||
|
|
||||||
```go
|
|
||||||
cfg.Section("advance").Key("ADDRESS").String()
|
|
||||||
|
|
||||||
/* --- start ---
|
|
||||||
404 road,
|
|
||||||
NotFound, State, 5000
|
|
||||||
Earth
|
|
||||||
------ end --- */
|
|
||||||
```
|
|
||||||
|
|
||||||
赞爆了！那要是我属于一行的内容写不下想要写到第二行怎么办？
|
|
||||||
|
|
||||||
```ini
|
|
||||||
[advance]
|
|
||||||
two_lines = how about \
|
|
||||||
continuation lines?
|
|
||||||
lots_of_lines = 1 \
|
|
||||||
2 \
|
|
||||||
3 \
|
|
||||||
4
|
|
||||||
```
|
|
||||||
|
|
||||||
简直是小菜一碟！
|
|
||||||
|
|
||||||
```go
|
|
||||||
cfg.Section("advance").Key("two_lines").String() // how about continuation lines?
|
|
||||||
cfg.Section("advance").Key("lots_of_lines").String() // 1 2 3 4
|
|
||||||
```
|
|
||||||
|
|
||||||
需要注意的是，值两侧的单引号会被自动剔除：
|
|
||||||
|
|
||||||
```ini
|
|
||||||
foo = "some value" // foo: some value
|
|
||||||
bar = 'some value' // bar: some value
|
|
||||||
```
|
|
||||||
|
|
||||||
这就是全部了？哈哈，当然不是。
|
|
||||||
|
|
||||||
#### 操作键值的辅助方法
|
|
||||||
|
|
||||||
获取键值时设定候选值：
|
|
||||||
|
|
||||||
```go
|
|
||||||
v = cfg.Section("").Key("STRING").In("default", []string{"str", "arr", "types"})
|
|
||||||
v = cfg.Section("").Key("FLOAT64").InFloat64(1.1, []float64{1.25, 2.5, 3.75})
|
|
||||||
v = cfg.Section("").Key("INT").InInt(5, []int{10, 20, 30})
|
|
||||||
v = cfg.Section("").Key("INT64").InInt64(10, []int64{10, 20, 30})
|
|
||||||
v = cfg.Section("").Key("UINT").InUint(4, []int{3, 6, 9})
|
|
||||||
v = cfg.Section("").Key("UINT64").InUint64(8, []int64{3, 6, 9})
|
|
||||||
v = cfg.Section("").Key("TIME").InTimeFormat(time.RFC3339, time.Now(), []time.Time{time1, time2, time3})
|
|
||||||
v = cfg.Section("").Key("TIME").InTime(time.Now(), []time.Time{time1, time2, time3}) // RFC3339
|
|
||||||
```
|
|
||||||
|
|
||||||
如果获取到的值不是候选值的任意一个，则会返回默认值，而默认值不需要是候选值中的一员。
|
|
||||||
|
|
||||||
验证获取的值是否在指定范围内：
|
|
||||||
|
|
||||||
```go
|
|
||||||
vals = cfg.Section("").Key("FLOAT64").RangeFloat64(0.0, 1.1, 2.2)
|
|
||||||
vals = cfg.Section("").Key("INT").RangeInt(0, 10, 20)
|
|
||||||
vals = cfg.Section("").Key("INT64").RangeInt64(0, 10, 20)
|
|
||||||
vals = cfg.Section("").Key("UINT").RangeUint(0, 3, 9)
|
|
||||||
vals = cfg.Section("").Key("UINT64").RangeUint64(0, 3, 9)
|
|
||||||
vals = cfg.Section("").Key("TIME").RangeTimeFormat(time.RFC3339, time.Now(), minTime, maxTime)
|
|
||||||
vals = cfg.Section("").Key("TIME").RangeTime(time.Now(), minTime, maxTime) // RFC3339
|
|
||||||
```
|
|
||||||
|
|
||||||
自动分割键值为切片（slice）：
|
|
||||||
|
|
||||||
```go
|
|
||||||
vals = cfg.Section("").Key("STRINGS").Strings(",")
|
|
||||||
vals = cfg.Section("").Key("FLOAT64S").Float64s(",")
|
|
||||||
vals = cfg.Section("").Key("INTS").Ints(",")
|
|
||||||
vals = cfg.Section("").Key("INT64S").Int64s(",")
|
|
||||||
vals = cfg.Section("").Key("UINTS").Uints(",")
|
|
||||||
vals = cfg.Section("").Key("UINT64S").Uint64s(",")
|
|
||||||
vals = cfg.Section("").Key("TIMES").Times(",")
|
|
||||||
```
|
|
||||||
|
|
||||||
### 保存配置
|
|
||||||
|
|
||||||
终于到了这个时刻，是时候保存一下配置了。
|
|
||||||
|
|
||||||
比较原始的做法是输出配置到某个文件：
|
|
||||||
|
|
||||||
```go
|
|
||||||
// ...
|
|
||||||
err = cfg.SaveTo("my.ini")
|
|
||||||
err = cfg.SaveToIndent("my.ini", "\t")
|
|
||||||
```
|
|
||||||
|
|
||||||
另一个比较高级的做法是写入到任何实现 `io.Writer` 接口的对象中：
|
|
||||||
|
|
||||||
```go
|
|
||||||
// ...
|
|
||||||
cfg.WriteTo(writer)
|
|
||||||
cfg.WriteToIndent(writer, "\t")
|
|
||||||
```
|
|
||||||
|
|
||||||
### 高级用法
|
|
||||||
|
|
||||||
#### 递归读取键值
|
|
||||||
|
|
||||||
在获取所有键值的过程中，特殊语法 `%(<name>)s` 会被应用，其中 `<name>` 可以是相同分区或者默认分区下的键名。字符串 `%(<name>)s` 会被相应的键值所替代，如果指定的键不存在，则会用空字符串替代。您可以最多使用 99 层的递归嵌套。
|
|
||||||
|
|
||||||
```ini
|
|
||||||
NAME = ini
|
|
||||||
|
|
||||||
[author]
|
|
||||||
NAME = Unknwon
|
|
||||||
GITHUB = https://github.com/%(NAME)s
|
|
||||||
|
|
||||||
[package]
|
|
||||||
FULL_NAME = github.com/go-ini/%(NAME)s
|
|
||||||
```
|
|
||||||
|
|
||||||
```go
|
|
||||||
cfg.Section("author").Key("GITHUB").String() // https://github.com/Unknwon
|
|
||||||
cfg.Section("package").Key("FULL_NAME").String() // github.com/go-ini/ini
|
|
||||||
```
|
|
||||||
|
|
||||||
#### 读取父子分区
|
|
||||||
|
|
||||||
您可以在分区名称中使用 `.` 来表示两个或多个分区之间的父子关系。如果某个键在子分区中不存在，则会去它的父分区中再次寻找，直到没有父分区为止。
|
|
||||||
|
|
||||||
```ini
|
|
||||||
NAME = ini
|
|
||||||
VERSION = v1
|
|
||||||
IMPORT_PATH = gopkg.in/%(NAME)s.%(VERSION)s
|
|
||||||
|
|
||||||
[package]
|
|
||||||
CLONE_URL = https://%(IMPORT_PATH)s
|
|
||||||
|
|
||||||
[package.sub]
|
|
||||||
```
|
|
||||||
|
|
||||||
```go
|
|
||||||
cfg.Section("package.sub").Key("CLONE_URL").String() // https://gopkg.in/ini.v1
|
|
||||||
```
|
|
||||||
|
|
||||||
#### 读取自增键名
|
|
||||||
|
|
||||||
如果数据源中的键名为 `-`，则认为该键使用了自增键名的特殊语法。计数器从 1 开始，并且分区之间是相互独立的。
|
|
||||||
|
|
||||||
```ini
|
|
||||||
[features]
|
|
||||||
-: Support read/write comments of keys and sections
|
|
||||||
-: Support auto-increment of key names
|
|
||||||
-: Support load multiple files to overwrite key values
|
|
||||||
```
|
|
||||||
|
|
||||||
```go
|
|
||||||
cfg.Section("features").KeyStrings() // []{"#1", "#2", "#3"}
|
|
||||||
```
|
|
||||||
|
|
||||||
### 映射到结构
|
|
||||||
|
|
||||||
想要使用更加面向对象的方式玩转 INI 吗？好主意。
|
|
||||||
|
|
||||||
```ini
|
|
||||||
Name = Unknwon
|
|
||||||
age = 21
|
|
||||||
Male = true
|
|
||||||
Born = 1993-01-01T20:17:05Z
|
|
||||||
|
|
||||||
[Note]
|
|
||||||
Content = Hi is a good man!
|
|
||||||
Cities = HangZhou, Boston
|
|
||||||
```
|
|
||||||
|
|
||||||
```go
|
|
||||||
type Note struct {
|
|
||||||
Content string
|
|
||||||
Cities []string
|
|
||||||
}
|
|
||||||
|
|
||||||
type Person struct {
|
|
||||||
Name string
|
|
||||||
Age int `ini:"age"`
|
|
||||||
Male bool
|
|
||||||
Born time.Time
|
|
||||||
Note
|
|
||||||
Created time.Time `ini:"-"`
|
|
||||||
}
|
|
||||||
|
|
||||||
func main() {
|
|
||||||
cfg, err := ini.Load("path/to/ini")
|
|
||||||
// ...
|
|
||||||
p := new(Person)
|
|
||||||
err = cfg.MapTo(p)
|
|
||||||
// ...
|
|
||||||
|
|
||||||
// 一切竟可以如此的简单。
|
|
||||||
err = ini.MapTo(p, "path/to/ini")
|
|
||||||
// ...
|
|
||||||
|
|
||||||
// 嗯哼？只需要映射一个分区吗？
|
|
||||||
n := new(Note)
|
|
||||||
err = cfg.Section("Note").MapTo(n)
|
|
||||||
// ...
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
结构的字段怎么设置默认值呢？很简单，只要在映射之前对指定字段进行赋值就可以了。如果键未找到或者类型错误，该值不会发生改变。
|
|
||||||
|
|
||||||
```go
|
|
||||||
// ...
|
|
||||||
p := &Person{
|
|
||||||
Name: "Joe",
|
|
||||||
}
|
|
||||||
// ...
|
|
||||||
```
|
|
||||||
|
|
||||||
这样玩 INI 真的好酷啊！然而，如果不能还给我原来的配置文件，有什么卵用？
|
|
||||||
|
|
||||||
### 从结构反射
|
|
||||||
|
|
||||||
可是，我有说不能吗？
|
|
||||||
|
|
||||||
```go
|
|
||||||
type Embeded struct {
|
|
||||||
Dates []time.Time `delim:"|"`
|
|
||||||
Places []string
|
|
||||||
None []int
|
|
||||||
}
|
|
||||||
|
|
||||||
type Author struct {
|
|
||||||
Name string `ini:"NAME"`
|
|
||||||
Male bool
|
|
||||||
Age int
|
|
||||||
GPA float64
|
|
||||||
NeverMind string `ini:"-"`
|
|
||||||
*Embeded
|
|
||||||
}
|
|
||||||
|
|
||||||
func main() {
|
|
||||||
a := &Author{"Unknwon", true, 21, 2.8, "",
|
|
||||||
&Embeded{
|
|
||||||
[]time.Time{time.Now(), time.Now()},
|
|
||||||
[]string{"HangZhou", "Boston"},
|
|
||||||
[]int{},
|
|
||||||
}}
|
|
||||||
cfg := ini.Empty()
|
|
||||||
err = ini.ReflectFrom(cfg, a)
|
|
||||||
// ...
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
瞧瞧，奇迹发生了。
|
|
||||||
|
|
||||||
```ini
|
|
||||||
NAME = Unknwon
|
|
||||||
Male = true
|
|
||||||
Age = 21
|
|
||||||
GPA = 2.8
|
|
||||||
|
|
||||||
[Embeded]
|
|
||||||
Dates = 2015-08-07T22:14:22+08:00|2015-08-07T22:14:22+08:00
|
|
||||||
Places = HangZhou,Boston
|
|
||||||
None =
|
|
||||||
```
|
|
||||||
|
|
||||||
#### 名称映射器（Name Mapper）
|
|
||||||
|
|
||||||
为了节省您的时间并简化代码，本库支持类型为 [`NameMapper`](https://gowalker.org/gopkg.in/ini.v1#NameMapper) 的名称映射器，该映射器负责结构字段名与分区名和键名之间的映射。
|
|
||||||
|
|
||||||
目前有 2 款内置的映射器：
|
|
||||||
|
|
||||||
- `AllCapsUnderscore`：该映射器将字段名转换至格式 `ALL_CAPS_UNDERSCORE` 后再去匹配分区名和键名。
|
|
||||||
- `TitleUnderscore`：该映射器将字段名转换至格式 `title_underscore` 后再去匹配分区名和键名。
|
|
||||||
|
|
||||||
使用方法：
|
|
||||||
|
|
||||||
```go
|
|
||||||
type Info struct{
|
|
||||||
PackageName string
|
|
||||||
}
|
|
||||||
|
|
||||||
func main() {
|
|
||||||
err = ini.MapToWithMapper(&Info{}, ini.TitleUnderscore, []byte("packag_name=ini"))
|
|
||||||
// ...
|
|
||||||
|
|
||||||
cfg, err := ini.Load([]byte("PACKAGE_NAME=ini"))
|
|
||||||
// ...
|
|
||||||
info := new(Info)
|
|
||||||
cfg.NameMapper = ini.AllCapsUnderscore
|
|
||||||
err = cfg.MapTo(info)
|
|
||||||
// ...
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
使用函数 `ini.ReflectFromWithMapper` 时也可应用相同的规则。
|
|
||||||
|
|
||||||
#### 映射/反射的其它说明
|
|
||||||
|
|
||||||
任何嵌入的结构都会被默认认作一个不同的分区，并且不会自动产生所谓的父子分区关联：
|
|
||||||
|
|
||||||
```go
|
|
||||||

## 常见问题
|
|
||||||
|
|
||||||
### 字段 `BlockMode` 是什么？
|
|
||||||
|
|
||||||
默认情况下，本库会在您进行读写操作时采用锁机制来确保数据时间。但在某些情况下，您非常确定只进行读操作。此时，您可以通过设置 `cfg.BlockMode = false` 来将读操作提升大约 **50-70%** 的性能。
|
|
||||||
|
|
||||||
### 为什么要写另一个 INI 解析库？
|
|
||||||
|
|
||||||
许多人都在使用我的 [goconfig](https://github.com/Unknwon/goconfig) 来完成对 INI 文件的操作，但我希望使用更加 Go 风格的代码。并且当您设置 `cfg.BlockMode = false` 时，会有大约 **10-30%** 的性能提升。
|
|
||||||
|
|
||||||
为了做出这些改变，我必须对 API 进行破坏，所以新开一个仓库是最安全的做法。除此之外，本库直接使用 `gopkg.in` 来进行版本化发布。（其实真相是导入路径更短了）

Bugsnag Notifier for Golang
|
|
||||||
===========================
|
|
||||||
|
|
||||||
The Bugsnag Notifier for Golang gives you instant notification of panics, or
|
|
||||||
unexpected errors, in your golang app. Any unhandled panics will trigger a
|
|
||||||
notification to be sent to your Bugsnag project.
|
|
||||||
|
|
||||||
[Bugsnag](http://bugsnag.com) captures errors in real-time from your web,
|
|
||||||
mobile and desktop applications, helping you to understand and resolve them
|
|
||||||
as fast as possible. [Create a free account](http://bugsnag.com) to start
|
|
||||||
capturing exceptions from your applications.
|
|
||||||
|
|
||||||
## How to Install
|
|
||||||
|
|
||||||
1. Download the code
|
|
||||||
|
|
||||||
```shell
|
|
||||||
go get github.com/bugsnag/bugsnag-go
|
|
||||||
```
|
|
||||||
|
|
||||||
### Using with net/http apps
|
|
||||||
|
|
||||||
For a golang app based on [net/http](https://godoc.org/net/http), integrating
|
|
||||||
Bugsnag takes two steps. You should also use these instructions if you're using
|
|
||||||
the [gorilla toolkit](http://www.gorillatoolkit.org/), or the
|
|
||||||
[pat](https://github.com/bmizerany/pat/) muxer.
|
|
||||||
|
|
||||||
1. Configure bugsnag at the start of your `main()` function:
|
|
||||||
|
|
||||||
```go
|
|
||||||
import "github.com/bugsnag/bugsnag-go"
|
|
||||||
|
|
||||||
func main() {
|
|
||||||
bugsnag.Configure(bugsnag.Configuration{
|
|
||||||
APIKey: "YOUR_API_KEY_HERE",
|
|
||||||
ReleaseStage: "production",
|
|
||||||
// more configuration options
|
|
||||||
})
|
|
||||||
|
|
||||||
// rest of your program.
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
2. Wrap your server in a [bugsnag.Handler](https://godoc.org/github.com/bugsnag/bugsnag-go/#Handler)
|
|
||||||
|
|
||||||
```go
|
|
||||||
// a. If you're using the builtin http mux, you can just pass
|
|
||||||
// bugsnag.Handler(nil) to http.ListenAndServer
|
|
||||||
http.ListenAndServe(":8080", bugsnag.Handler(nil))
|
|
||||||
|
|
||||||
// b. If you're creating a server manually yourself, you can set
|
|
||||||
// its handlers the same way
|
|
||||||
srv := http.Server{
|
|
||||||
Handler: bugsnag.Handler(nil)
|
|
||||||
}
|
|
||||||
|
|
||||||
// c. If you're not using the builtin http mux, wrap your own handler
|
|
||||||
// (though make sure that it doesn't already catch panics)
|
|
||||||
http.ListenAndServe(":8080", bugsnag.Handler(handler))
|
|
||||||
```
|
|
||||||
|
|
||||||
### Using with Revel apps
|
|
||||||
|
|
||||||
There are two steps to get panic handling in [revel](https://revel.github.io) apps.
|
|
||||||
|
|
||||||
1. Add the `bugsnagrevel.Filter` immediately after the `revel.PanicFilter` in `app/init.go`:
|
|
||||||
|
|
||||||
```go
|
|
||||||
|
|
||||||
import "github.com/bugsnag/bugsnag-go/revel"
|
|
||||||
|
|
||||||
revel.Filters = []revel.Filter{
|
|
||||||
revel.PanicFilter,
|
|
||||||
bugsnagrevel.Filter,
|
|
||||||
// ...
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
2. Set bugsnag.apikey in the top section of `conf/app.conf`.
|
|
||||||
|
|
||||||
```
|
|
||||||
module.static=github.com/revel/revel/modules/static
|
|
||||||
|
|
||||||
bugsnag.apikey=YOUR_API_KEY_HERE
|
|
||||||
|
|
||||||
[dev]
|
|
||||||
```
|
|
||||||
|
|
||||||
### Using with Google App Engine
|
|
||||||
|
|
||||||
1. Configure bugsnag at the start of your `init()` function:
|
|
||||||
|
|
||||||
```go
|
|
||||||
import "github.com/bugsnag/bugsnag-go"
|
|
||||||
|
|
||||||
func init() {
|
|
||||||
bugsnag.Configure(bugsnag.Configuration{
|
|
||||||
APIKey: "YOUR_API_KEY_HERE",
|
|
||||||
})
|
|
||||||
|
|
||||||
// ...
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
2. Wrap *every* http.Handler or http.HandlerFunc with Bugsnag:
|
|
||||||
|
|
||||||
```go
|
|
||||||
// a. If you're using HandlerFuncs
|
|
||||||
http.HandleFunc("/", bugsnag.HandlerFunc(
|
|
||||||
func (w http.ResponseWriter, r *http.Request) {
|
|
||||||
// ...
|
|
||||||
}))
|
|
||||||
|
|
||||||
// b. If you're using Handlers
|
|
||||||
http.Handle("/", bugsnag.Handler(myHttpHandler))
|
|
||||||
```
|
|
||||||
|
|
||||||
3. In order to use Bugsnag, you must provide the current
|
|
||||||
[`appengine.Context`](https://developers.google.com/appengine/docs/go/reference#Context), or
|
|
||||||
current `*http.Request` as rawData. The easiest way to do this is to create a new notifier.
|
|
||||||
|
|
||||||
```go
|
|
||||||
c := appengine.NewContext(r)
|
|
||||||
notifier := bugsnag.New(c)
|
|
||||||
|
|
||||||
if err != nil {
|
|
||||||
notifier.Notify(err)
|
|
||||||
}
|
|
||||||
|
|
||||||
go func () {
|
|
||||||
defer notifier.Recover()
|
|
||||||
|
|
||||||
// ...
|
|
||||||
}()
|
|
||||||
```
|
|
||||||
|
|
||||||
|
|
||||||
## Notifying Bugsnag manually
|
|
||||||
|
|
||||||
Bugsnag will automatically handle any panics that crash your program and notify
|
|
||||||
you of them. If you've integrated with `revel` or `net/http`, then you'll also
|
|
||||||
be notified of any panics() that happen while processing a request.
|
|
||||||
|
|
||||||
Sometimes however it's useful to manually notify Bugsnag of a problem. To do this,
|
|
||||||
call [`bugsnag.Notify()`](https://godoc.org/github.com/bugsnag/bugsnag-go/#Notify)
|
|
||||||
|
|
||||||
```go
|
|
||||||
if err != nil {
|
|
||||||
bugsnag.Notify(err)
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### Manual panic handling
|
|
||||||
|
|
||||||
To avoid a panic in a goroutine from crashing your entire app, you can use
|
|
||||||
[`bugsnag.Recover()`](https://godoc.org/github.com/bugsnag/bugsnag-go/#Recover)
|
|
||||||
to stop a panic from unwinding the stack any further. When `Recover()` is hit,
|
|
||||||
it will send any current panic to Bugsnag and then stop panicking. This is
|
|
||||||
most useful at the start of a goroutine:
|
|
||||||
|
|
||||||
```go
|
|
||||||
go func() {
|
|
||||||
defer bugsnag.Recover()
|
|
||||||
|
|
||||||
// ...
|
|
||||||
}()
|
|
||||||
```
|
|
||||||
|
|
||||||
Alternatively you can use
|
|
||||||
[`bugsnag.AutoNotify()`](https://godoc.org/github.com/bugsnag/bugsnag-go/#Recover)
|
|
||||||
to notify bugsnag of a panic while letting the program continue to panic. This
|
|
||||||
is useful if you're using a Framework that already has some handling of panics
|
|
||||||
and you are retrofitting bugsnag support.
|
|
||||||
|
|
||||||
```go
|
|
||||||
defer bugsnag.AutoNotify()
|
|
||||||
```
|
|
||||||
|
|
||||||
## Sending Custom Data
|
|
||||||
|
|
||||||
Most functions in the Bugsnag API, including `bugsnag.Notify()`,
|
|
||||||
`bugsnag.Recover()`, `bugsnag.AutoNotify()`, and `bugsnag.Handler()` let you
|
|
||||||
attach data to the notifications that they send. To do this you pass in rawData,
|
|
||||||
which can be any of the supported types listed here. To add support for more
|
|
||||||
types of rawData see [OnBeforeNotify](#custom-data-with-onbeforenotify).
|
|
||||||
|
|
||||||
### Custom MetaData
|
|
||||||
|
|
||||||
Custom metaData appears as tabs on Bugsnag.com. You can set it by passing
|
|
||||||
a [`bugsnag.MetaData`](https://godoc.org/github.com/bugsnag/bugsnag-go/#MetaData)
|
|
||||||
object as rawData.
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Notify(err,
|
|
||||||
bugsnag.MetaData{
|
|
||||||
"Account": {
|
|
||||||
"Name": Account.Name,
|
|
||||||
"Paying": Account.Plan.Premium,
|
|
||||||
},
|
|
||||||
})
|
|
||||||
```
|
|
||||||
|
|
||||||
### Request data
|
|
||||||
|
|
||||||
Bugsnag can extract interesting data from
|
|
||||||
[`*http.Request`](https://godoc.org/net/http/#Request) objects, and
|
|
||||||
[`*revel.Controller`](https://godoc.org/github.com/revel/revel/#Controller)
|
|
||||||
objects. These are automatically passed in when handling panics, and you can
|
|
||||||
pass them yourself.
|
|
||||||
|
|
||||||
```go
|
|
||||||
func (w http.ResponseWriter, r *http.Request) {
|
|
||||||
bugsnag.Notify(err, r)
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### User data
|
|
||||||
|
|
||||||
User data is searchable, and the `Id` powers the count of users affected. You
|
|
||||||
can set which user an error affects by passing a
|
|
||||||
[`bugsnag.User`](https://godoc.org/github.com/bugsnag/bugsnag-go/#User) object as
|
|
||||||
rawData.
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Notify(err,
|
|
||||||
bugsnag.User{Id: "1234", Name: "Conrad", Email: "me@cirw.in"})
|
|
||||||
```
|
|
||||||
|
|
||||||
### Context
|
|
||||||
|
|
||||||
The context shows up prominently in the list view so that you can get an idea
|
|
||||||
of where a problem occurred. You can set it by passing a
|
|
||||||
[`bugsnag.Context`](https://godoc.org/github.com/bugsnag/bugsnag-go/#Context)
|
|
||||||
object as rawData.
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Notify(err, bugsnag.Context{"backgroundJob"})
|
|
||||||
```
|
|
||||||
|
|
||||||
### Severity
|
|
||||||
|
|
||||||
Bugsnag supports three severities, `SeverityError`, `SeverityWarning`, and `SeverityInfo`.
|
|
||||||
You can set the severity of an error by passing one of these objects as rawData.
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Notify(err, bugsnag.SeverityInfo)
|
|
||||||
```
|
|
||||||
|
|
||||||
## Configuration
|
|
||||||
|
|
||||||
You must call `bugsnag.Configure()` at the start of your program to use Bugsnag, you pass it
|
|
||||||
a [`bugsnag.Configuration`](https://godoc.org/github.com/bugsnag/bugsnag-go/#Configuration) object
|
|
||||||
containing any of the following values.
|
|
||||||
|
|
||||||
### APIKey
|
|
||||||
|
|
||||||
The Bugsnag API key can be found on your [Bugsnag dashboard](https://bugsnag.com) under "Settings".
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Configure(bugsnag.Configuration{
|
|
||||||
APIKey: "YOUR_API_KEY_HERE",
|
|
||||||
})
|
|
||||||
```
|
|
||||||
|
|
||||||
### Endpoint
|
|
||||||
|
|
||||||
The Bugsnag endpoint defaults to `https://notify.bugsnag.com/`. If you're using Bugsnag enterprise,
|
|
||||||
you should set this to the endpoint of your local instance.
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Configure(bugsnag.Configuration{
|
|
||||||
Endpoint: "http://bugsnag.internal:49000/",
|
|
||||||
})
|
|
||||||
```
|
|
||||||
|
|
||||||
### ReleaseStage
|
|
||||||
|
|
||||||
The ReleaseStage tracks where your app is deployed. You should set this to `production`, `staging`,
|
|
||||||
`development` or similar as appropriate.
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Configure(bugsnag.Configuration{
|
|
||||||
ReleaseStage: "development",
|
|
||||||
})
|
|
||||||
```
|
|
||||||
|
|
||||||
### NotifyReleaseStages
|
|
||||||
|
|
||||||
The list of ReleaseStages to notify in. By default Bugsnag will notify you in all release stages, but
|
|
||||||
you can use this to silence development errors.
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Configure(bugsnag.Configuration{
|
|
||||||
NotifyReleaseStages: []string{"production", "staging"},
|
|
||||||
})
|
|
||||||
```
|
|
||||||
|
|
||||||
### AppVersion
|
|
||||||
|
|
||||||
If you use a versioning scheme for deploys of your app, Bugsnag can use the `AppVersion` to only
|
|
||||||
re-open errors if they occur in later version of the app.
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Configure(bugsnag.Configuration{
|
|
||||||
AppVersion: "1.2.3",
|
|
||||||
})
|
|
||||||
```
|
|
||||||
|
|
||||||
### Hostname
|
|
||||||
|
|
||||||
The hostname is used to track where exceptions are coming from in the Bugsnag dashboard. The
|
|
||||||
default value is obtained from `os.Hostname()` so you won't often need to change this.
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Configure(bugsnag.Configuration{
|
|
||||||
Hostname: "go1",
|
|
||||||
})
|
|
||||||
```
|
|
||||||
|
|
||||||
### ProjectPackages
|
|
||||||
|
|
||||||
In order to determine where a crash happens Bugsnag needs to know which packages you consider to
|
|
||||||
be part of your app (as opposed to a library). By default this is set to `[]string{"main*"}`. Strings
|
|
||||||
are matched to package names using [`filepath.Match`](http://godoc.org/path/filepath#Match).
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Configure(bugsnag.Configuration{
|
|
||||||
ProjectPackages: []string{"main", "github.com/domain/myapp/*"},
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### ParamsFilters
|
|
||||||
|
|
||||||
Sometimes sensitive data is accidentally included in Bugsnag MetaData. You can remove it by
|
|
||||||
setting `ParamsFilters`. Any key in the `MetaData` that includes any string in the filters
|
|
||||||
will be redacted. The default is `[]string{"password", "secret"}`, which prevents fields like
|
|
||||||
`password`, `password_confirmation` and `secret_answer` from being sent.
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Configure(bugsnag.Configuration{
|
|
||||||
ParamsFilters: []string{"password", "secret"},
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### Logger
|
|
||||||
|
|
||||||
The Logger to write to in case of an error inside Bugsnag. This defaults to the global logger.
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Configure(bugsnag.Configuration{
|
|
||||||
Logger: app.Logger,
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### PanicHandler
|
|
||||||
|
|
||||||
The first time Bugsnag is configured, it wraps the running program in a panic
|
|
||||||
handler using [panicwrap](http://godoc.org/github.com/ConradIrwin/panicwrap). This
|
|
||||||
forks a sub-process which monitors unhandled panics. To prevent this, set
|
|
||||||
`PanicHandler` to `func() {}` the first time you call
|
|
||||||
`bugsnag.Configure`. This will prevent bugsnag from being able to notify you about
|
|
||||||
unhandled panics.
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Configure(bugsnag.Configuration{
|
|
||||||
PanicHandler: func() {},
|
|
||||||
})
|
|
||||||
```
|
|
||||||
|
|
||||||
### Synchronous
|
|
||||||
|
|
||||||
Bugsnag usually starts a new goroutine before sending notifications. This means
|
|
||||||
that notifications can be lost if you do a bugsnag.Notify and then immediately
|
|
||||||
os.Exit. To avoid this problem, set Bugsnag to Synchronous (or just `panic()`
|
|
||||||
instead ;).
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Configure(bugsnag.Configuration{
|
|
||||||
Synchronous: true
|
|
||||||
})
|
|
||||||
```
|
|
||||||
|
|
||||||
Or just for one error:
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Notify(err, bugsnag.Configuration{Synchronous: true})
|
|
||||||
```
|
|
||||||
|
|
||||||
### Transport
|
|
||||||
|
|
||||||
The transport configures how Bugsnag makes http requests. By default we use
|
|
||||||
[`http.DefaultTransport`](http://godoc.org/net/http#RoundTripper) which handles
|
|
||||||
HTTP proxies automatically using the `$HTTP_PROXY` environment variable.
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Configure(bugsnag.Configuration{
|
|
||||||
Transport: http.DefaultTransport,
|
|
||||||
})
|
|
||||||
```
|
|
||||||
|
|
||||||
## Custom data with OnBeforeNotify
|
|
||||||
|
|
||||||
While it's nice that you can pass `MetaData` directly into `bugsnag.Notify`,
|
|
||||||
`bugsnag.AutoNotify`, and `bugsnag.Recover`, this can be a bit cumbersome and
|
|
||||||
inefficient — you're constructing the meta-data whether or not it will actually
|
|
||||||
be used. A better idea is to pass raw data in to these functions, and add an
|
|
||||||
`OnBeforeNotify` filter that converts them into `MetaData`.
|
|
||||||
|
|
||||||
For example, lets say our system processes jobs:
|
|
||||||
|
|
||||||
```go
|
|
||||||
type Job struct{
|
|
||||||
Retry bool
|
|
||||||
UserId string
|
|
||||||
UserEmail string
|
|
||||||
Name string
|
|
||||||
Params map[string]string
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
You can pass a job directly into Bugsnag.notify:
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Notify(err, job)
|
|
||||||
```
|
|
||||||
|
|
||||||
And then add a filter to extract information from that job and attach it to the
|
|
||||||
Bugsnag event:
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.OnBeforeNotify(
|
|
||||||
func(event *bugsnag.Event, config *bugsnag.Configuration) error {
|
|
||||||
|
|
||||||
// Search all the RawData for any *Job pointers that we're passed in
|
|
||||||
// to bugsnag.Notify() and friends.
|
|
||||||
for _, datum := range event.RawData {
|
|
||||||
if job, ok := datum.(*Job); ok {
|
|
||||||
// don't notify bugsnag about errors in retries
|
|
||||||
if job.Retry {
|
|
||||||
return fmt.Errorf("not notifying about retried jobs")
|
|
||||||
}
|
|
||||||
|
|
||||||
// add the job as a tab on Bugsnag.com
|
|
||||||
event.MetaData.AddStruct("Job", job)
|
|
||||||
|
|
||||||
// set the user correctly
|
|
||||||
event.User = &User{Id: job.UserId, Email: job.UserEmail}
|
|
||||||
}
|
|
||||||
}
|
|
||||||
|
|
||||||
// continue notifying as normal
|
|
||||||
return nil
|
|
||||||
})
|
|
||||||
```
|
|
||||||
|
|
||||||
## Advanced Usage
|
|
||||||
|
|
||||||
If you want to have multiple different configurations around in one program,
|
|
||||||
you can use `bugsnag.New()` to create multiple independent instances of
|
|
||||||
Bugsnag. You can use these without calling `bugsnag.Configure()`, but bear in
|
|
||||||
mind that until you call `bugsnag.Configure()` unhandled panics will not be
|
|
||||||
sent to bugsnag.
|
|
||||||
|
|
||||||
```go
|
|
||||||
notifier := bugsnag.New(bugsnag.Configuration{
|
|
||||||
APIKey: "YOUR_OTHER_API_KEY",
|
|
||||||
})
|
|
||||||
```
|
|
||||||
|
|
||||||
In fact any place that lets you pass in `rawData` also allows you to pass in
|
|
||||||
configuration. For example to send http errors to one bugsnag project, you
|
|
||||||
could do:
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.Handler(nil, bugsnag.Configuration{APIKey: "YOUR_OTHER_API_KEY"})
|
|
||||||
```
|
|
||||||
|
|
||||||
### GroupingHash
|
|
||||||
|
|
||||||
If you need to override Bugsnag's grouping algorithm, you can set the
|
|
||||||
`GroupingHash` in an `OnBeforeNotify`:
|
|
||||||
|
|
||||||
```go
|
|
||||||
bugsnag.OnBeforeNotify(
|
|
||||||
func (event *bugsnag.Event, config *bugsnag.Configuration) error {
|
|
||||||
event.GroupingHash = calculateGroupingHash(event)
|
|
||||||
return nil
|
|
||||||
})
|
|
||||||
```

# panicwrap
|
|
||||||
|
|
||||||
panicwrap is a Go library that re-executes a Go binary and monitors stderr
|
|
||||||
output from the binary for a panic. When it find a panic, it executes a
|
|
||||||
user-defined handler function. Stdout, stderr, stdin, signals, and exit
|
|
||||||
codes continue to work as normal, making the existence of panicwrap mostly
|
|
||||||
invisble to the end user until a panic actually occurs.
|
|
||||||
|
|
||||||
Since a panic is truly a bug in the program meant to crash the runtime,
|
|
||||||
globally catching panics within Go applications is not supposed to be possible.
|
|
||||||
Despite this, it is often useful to have a way to know when panics occur.
|
|
||||||
panicwrap allows you to do something with these panics, such as writing them
|
|
||||||
to a file, so that you can track when panics occur.
|
|
||||||
|
|
||||||
panicwrap is ***not a panic recovery system***. Panics indicate serious
|
|
||||||
problems with your application and _should_ crash the runtime. panicwrap
|
|
||||||
is just meant as a way to monitor for panics. If you still think this is
|
|
||||||
the worst idea ever, read the section below on why.
|
|
||||||
|
|
||||||
## Features
|
|
||||||
|
|
||||||
* **SIMPLE!**
|
|
||||||
* Works with all Go applications on all platforms Go supports
|
|
||||||
* Custom behavior when a panic occurs
|
|
||||||
* Stdout, stderr, stdin, exit codes, and signals continue to work as
|
|
||||||
expected.
|
|
||||||
|
|
||||||
## Usage
|
|
||||||
|
|
||||||
Using panicwrap is simple. It behaves a lot like `fork`, if you know
|
|
||||||
how that works. A basic example is shown below.
|
|
||||||
|
|
||||||
Because it would be sad to panic while capturing a panic, it is recommended
|
|
||||||
that the handler functions for panicwrap remain relatively simple and well
|
|
||||||
tested. panicwrap itself contains many tests.
|
|
||||||
|
|
||||||
```go
|
|
||||||
package main
|
|
||||||
|
|
||||||
import (
|
|
||||||
"fmt"
|
|
||||||
"github.com/mitchellh/panicwrap"
|
|
||||||
"os"
|
|
||||||
)
|
|
||||||
|
|
||||||
func main() {
|
|
||||||
exitStatus, err := panicwrap.BasicWrap(panicHandler)
|
|
||||||
if err != nil {
|
|
||||||
// Something went wrong setting up the panic wrapper. Unlikely,
|
|
||||||
// but possible.
|
|
||||||
panic(err)
|
|
||||||
}
|
|
||||||
|
|
||||||
// If exitStatus >= 0, then we're the parent process and the panicwrap
|
|
||||||
// re-executed ourselves and completed. Just exit with the proper status.
|
|
||||||
if exitStatus >= 0 {
|
|
||||||
os.Exit(exitStatus)
|
|
||||||
}
|
|
||||||
|
|
||||||
// Otherwise, exitStatus < 0 means we're the child. Continue executing as
|
|
||||||
// normal...
|
|
||||||
|
|
||||||
// Let's say we panic
|
|
||||||
panic("oh shucks")
|
|
||||||
}
|
|
||||||
|
|
||||||
func panicHandler(output string) {
|
|
||||||
// output contains the full output (including stack traces) of the
|
|
||||||
// panic. Put it in a file or something.
|
|
||||||
fmt.Printf("The child panicked:\n\n%s\n", output)
|
|
||||||
os.Exit(1)
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
## How Does it Work?
|
|
||||||
|
|
||||||
panicwrap works by re-executing the running program (retaining arguments,
|
|
||||||
environmental variables, etc.) and monitoring the stderr of the program.
|
|
||||||
Since Go always outputs panics in a predictable way with a predictable
|
|
||||||
exit code, panicwrap is able to reliably detect panics and allow the parent
|
|
||||||
process to handle them.
|
|
||||||
|
|
||||||
## WHY?! Panics should CRASH!
|
|
||||||
|
|
||||||
Yes, panics _should_ crash. They are 100% always indicative of bugs.
|
|
||||||
However, in some cases, such as user-facing programs (programs like
|
|
||||||
[Packer](http://github.com/mitchellh/packer) or
|
|
||||||
[Docker](http://github.com/dotcloud/docker)), it is up to the user to
|
|
||||||
report such panics. This is unreliable, at best, and it would be better if the
|
|
||||||
program could have a way to automatically report panics. panicwrap provides
|
|
||||||
a way to do this.
|
|
||||||
|
|
||||||
For backend applications, it is easier to detect crashes (since the application
|
|
||||||
exits). However, it is still nice sometimes to more intelligently log
|
|
||||||
panics in some way. For example, at [HashiCorp](http://www.hashicorp.com),
|
|
||||||
we use panicwrap to log panics to timestamped files with some additional
|
|
||||||
data (configuration settings at the time, environmental variables, etc.)
|
|
||||||
|
|
||||||
The goal of panicwrap is _not_ to hide panics. It is instead to provide
|
|
||||||
a clean mechanism for handling them before bubbling the up to the user
|
|
||||||
and ultimately crashing.

excluding communication that is conspicuously marked or otherwise

designated in writing by the copyright owner as "Not a Contribution."
|
|

2. Grant of Copyright License. Subject to the terms and conditions of
|
|
||||||
this License, each Contributor hereby grants to You a perpetual,

copyright license to reproduce, prepare Derivative Works of,

|
||||||
publicly display, publicly perform, sublicense, and distribute the

|
||||||
modifications, and in Source or Object form, provided that You
|
|
||||||
meet the following conditions:
|
|

|
|
||||||
(a) You must give any other recipients of the Work or

|
||||||
Derivative Works a copy of this License; and
|
|
||||||
|
|
||||||
(b) You must cause any modified files to carry prominent notices
|
|
||||||
stating that You changed the files; and
|
|
||||||
|
|
||||||
(c) You must retain, in the Source form of any Derivative Works
|
|
||||||
that You distribute, all copyright, patent, trademark, and
|
|
||||||
attribution notices from the Source form of the Work,
|
|
||||||
excluding those notices that do not pertain to any part of
|
|
||||||
the Derivative Works; and
|
|
||||||
|
|
||||||
(d) If the Work includes a "NOTICE" text file as part of its
|
|
||||||
distribution, then any Derivative Works that You distribute must
|
|
||||||
include a readable copy of the attribution notices contained
|
|
||||||
within such NOTICE file, excluding those notices that do not
|
|
||||||
pertain to any part of the Derivative Works, in at least one
|
|
||||||
of the following places: within a NOTICE text file distributed
|
|
||||||
as part of the Derivative Works; within the Source form or
|
|
||||||
documentation, if provided along with the Derivative Works; or,
|
|
||||||
within a display generated by the Derivative Works, if and
|
|
||||||
wherever such third-party notices normally appear. The contents
|
|
||||||
of the NOTICE file are for informational purposes only and
|
|
||||||
do not modify the License. You may add Your own attribution
|
|
||||||
notices within Derivative Works that You distribute, alongside
|
|
||||||
or as an addendum to the NOTICE text from the Work, provided
|
|
||||||
that such additional attribution notices cannot be construed
|
|
||||||
as modifying the License.
|
|
||||||
|
|
||||||
You may add Your own copyright statement to Your modifications and
|
|
||||||
may provide additional or different license terms and conditions
|
|
||||||
for use, reproduction, or distribution of Your modifications, or
|
|
||||||
for any such Derivative Works as a whole, provided Your use,
|
|
||||||
reproduction, and distribution of the Work otherwise complies with
|
|
||||||
the conditions stated in this License.
|
|
||||||
|
|
||||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
|
||||||
any Contribution intentionally submitted for inclusion in the Work
|
|
||||||
by You to the Licensor shall be under the terms and conditions of
|
|
||||||
this License, without any additional terms or conditions.
|
|
||||||
Notwithstanding the above, nothing herein shall supersede or modify
|
|
||||||
the terms of any separate license agreement you may have executed
|
|
||||||
with Licensor regarding such Contributions.
|
|
||||||
|
|
||||||
6. Trademarks. This License does not grant permission to use the trade
|
|
||||||
names, trademarks, service marks, or product names of the Licensor,
|
|
||||||
except as required for reasonable and customary use in describing the
|
|
||||||
origin of the Work and reproducing the content of the NOTICE file.
|
|
||||||
|
|
||||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
|
||||||
agreed to in writing, Licensor provides the Work (and each
|
|
||||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
|
||||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
|
||||||
implied, including, without limitation, any warranties or conditions
|
|
||||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
|
||||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
|
||||||
appropriateness of using or redistributing the Work and assume any
|
|
||||||
risks associated with Your exercise of permissions under this License.
|
|
||||||
|
|
||||||
8. Limitation of Liability. In no event and under no legal theory,
|
|
||||||
whether in tort (including negligence), contract, or otherwise,
|
|
||||||
unless required by applicable law (such as deliberate and grossly
|
|
||||||
negligent acts) or agreed to in writing, shall any Contributor be
|
|
||||||
liable to You for damages, including any direct, indirect, special,
|
|
||||||
incidental, or consequential damages of any character arising as a
|
|
||||||
result of this License or out of the use or inability to use the
|
|
||||||
Work (including but not limited to damages for loss of goodwill,
|
|
||||||
work stoppage, computer failure or malfunction, or any and all
|
|
||||||
other commercial damages or losses), even if such Contributor
|
|
||||||
has been advised of the possibility of such damages.
|
|
||||||
|
|
||||||
9. Accepting Warranty or Additional Liability. While redistributing
|
|
||||||
the Work or Derivative Works thereof, You may choose to offer,
|
|
||||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
|
||||||
or other liability obligations and/or rights consistent with this
|
|
||||||
License. However, in accepting such obligations, You may act only
|
|
||||||
on Your own behalf and on Your sole responsibility, not on behalf
|
|
||||||
of any other Contributor, and only if You agree to indemnify,
|
|
||||||
defend, and hold each Contributor harmless for any liability
|
|
||||||
incurred by, or claims asserted against, such Contributor by reason
|
|
||||||
of your accepting any such warranty or additional liability.

# libtrust
|
|
||||||
|
|
||||||
Libtrust is library for managing authentication and authorization using public key cryptography.
|
|
||||||
|
|
||||||
Authentication is handled using the identity attached to the public key.
|
|
||||||
Libtrust provides multiple methods to prove possession of the private key associated with an identity.
|
|
||||||
- TLS x509 certificates
|
|
||||||
- Signature verification
|
|
||||||
- Key Challenge
|
|
||||||
|
|
||||||
Authorization and access control is managed through a distributed trust graph.
|
|
||||||
Trust servers are used as the authorities of the trust graph and allow caching portions of the graph for faster access.

================
|
|
||||||
[](https://godoc.org/github.com/gorilla/handlers) [](https://travis-ci.org/gorilla/handlers)
|
|
||||||
|
|
||||||
Package handlers is a collection of handlers (aka "HTTP middleware") for use
|
|
||||||
with Go's `net/http` package (or any framework supporting `http.Handler`), including:
|
|
||||||
|
|
||||||
* `LoggingHandler` for logging HTTP requests in the Apache [Common Log
|
|
||||||
Format](http://httpd.apache.org/docs/2.2/logs.html#common).
|
|
||||||
* `CombinedLoggingHandler` for logging HTTP requests in the Apache [Combined Log
|
|
||||||
Format](http://httpd.apache.org/docs/2.2/logs.html#combined) commonly used by
|
|
||||||
both Apache and nginx.
|
|
||||||
* `CompressHandler` for gzipping responses.
|
|
||||||
* `ContentTypeHandler` for validating requests against a list of accepted
|
|
||||||
content types.
|
|
||||||
* `MethodHandler` for matching HTTP methods against handlers in a
|
|
||||||
`map[string]http.Handler`
|
|
||||||
* `ProxyHeaders` for populating `r.RemoteAddr` and `r.URL.Scheme` based on the
|
|
||||||
`X-Forwarded-For`, `X-Real-IP`, `X-Forwarded-Proto` and RFC7239 `Forwarded`
|
|
||||||
headers when running a Go server behind a HTTP reverse proxy.
|
|
||||||
* `CanonicalHost` for re-directing to the preferred host when handling multiple
|
|
||||||
domains (i.e. multiple CNAME aliases).
|
|
||||||
|
|
||||||
Other handlers are documented [on the Gorilla
|
|
||||||
website](http://www.gorillatoolkit.org/pkg/handlers).
|
|
||||||
|
|
||||||
## Example
|
|
||||||
|
|
||||||
A simple example using `handlers.LoggingHandler` and `handlers.CompressHandler`:
|
|
||||||
|
|
||||||
```go
|
|
||||||
import (
|
|
||||||
"net/http"
|
|
||||||
"github.com/gorilla/handlers"
|
|
||||||
)
|
|
||||||
|
|
||||||
func main() {
|
|
||||||
r := http.NewServeMux()
|
|
||||||
|
|
||||||
// Only log requests to our admin dashboard to stdout
|
|
||||||
r.Handle("/admin", handlers.LoggingHandler(os.Stdout, http.HandlerFunc(ShowAdminDashboard)))
|
|
||||||
r.HandleFunc("/", ShowIndex)
|
|
||||||
|
|
||||||
// Wrap our server with our gzip handler to gzip compress all responses.
|
|
||||||
http.ListenAndServe(":8000", handlers.CompressHandler(r))
|
|
||||||
}
|
|
||||||
```

# mousetrap
|
|
||||||
|
|
||||||
mousetrap is a tiny library that answers a single question.
|
|
||||||
|
|
||||||
On a Windows machine, was the process invoked by someone double clicking on
|
|
||||||
the executable file while browsing in explorer?
|
|
||||||
|
|
||||||
### Motivation
|
|
||||||
|
|
||||||
Windows developers unfamiliar with command line tools will often "double-click"
|
|
||||||
the executable for a tool. Because most CLI tools print the help and then exit
|
|
||||||
when invoked without arguments, this is often very frustrating for those users.
|
|
||||||
|
|
||||||
mousetrap provides a way to detect these invocations so that you can provide
|
|
||||||
more helpful behavior and instructions on how to run the CLI tool. To see what
|
|
||||||
this looks like, both from an organizational and a technical perspective, see
|
|
||||||
https://inconshreveable.com/09-09-2014/sweat-the-small-stuff/
|
|
||||||
|
|
||||||
### The interface
|
|
||||||
|
|
||||||
The library exposes a single interface:
|
|
||||||
|
|
||||||
func StartedByExplorer() (bool)

/*
|
||||||
|
Package dns implements a full featured interface to the Domain Name System.
|
||||||
|
Server- and client-side programming is supported.
|
||||||
|
The package allows complete control over what is send out to the DNS. The package
|
||||||
|
API follows the less-is-more principle, by presenting a small, clean interface.
|
||||||
|
|
||||||
|
The package dns supports (asynchronous) querying/replying, incoming/outgoing zone transfers,
|
||||||
|
TSIG, EDNS0, dynamic updates, notifies and DNSSEC validation/signing.
|
||||||
|
Note that domain names MUST be fully qualified, before sending them, unqualified
|
||||||
|
names in a message will result in a packing failure.
|
||||||
|
|
||||||
|
Resource records are native types. They are not stored in wire format.
|
||||||
|
Basic usage pattern for creating a new resource record:
|
||||||
|
|
||||||
|
r := new(dns.MX)
|
||||||
|
r.Hdr = dns.RR_Header{Name: "miek.nl.", Rrtype: dns.TypeMX,
|
||||||
|
Class: dns.ClassINET, Ttl: 3600}
|
||||||
|
r.Preference = 10
|
||||||
|
r.Mx = "mx.miek.nl."
|
||||||
|
|
||||||
|
Or directly from a string:
|
||||||
|
|
||||||
|
mx, err := dns.NewRR("miek.nl. 3600 IN MX 10 mx.miek.nl.")
|
||||||
|
|
||||||
|
Or when the default TTL (3600) and class (IN) suit you:
|
||||||
|
|
||||||
|
mx, err := dns.NewRR("miek.nl. MX 10 mx.miek.nl.")
|
||||||
|
|
||||||
|
Or even:
|
||||||
|
|
||||||
|
mx, err := dns.NewRR("$ORIGIN nl.\nmiek 1H IN MX 10 mx.miek")
|
||||||
|
|
||||||
|
In the DNS messages are exchanged, these messages contain resource
|
||||||
|
records (sets). Use pattern for creating a message:
|
||||||
|
|
||||||
|
m := new(dns.Msg)
|
||||||
|
m.SetQuestion("miek.nl.", dns.TypeMX)
|
||||||
|
|
||||||
|
Or when not certain if the domain name is fully qualified:
|
||||||
|
|
||||||
|
m.SetQuestion(dns.Fqdn("miek.nl"), dns.TypeMX)
|
||||||
|
|
||||||
|
The message m is now a message with the question section set to ask
|
||||||
|
the MX records for the miek.nl. zone.
|
||||||
|
|
||||||
|
The following is slightly more verbose, but more flexible:
|
||||||
|
|
||||||
|
m1 := new(dns.Msg)
|
||||||
|
m1.Id = dns.Id()
|
||||||
|
m1.RecursionDesired = true
|
||||||
|
m1.Question = make([]dns.Question, 1)
|
||||||
|
m1.Question[0] = dns.Question{"miek.nl.", dns.TypeMX, dns.ClassINET}
|
||||||
|
|
||||||
|
After creating a message it can be send.
|
||||||
|
Basic use pattern for synchronous querying the DNS at a
|
||||||
|
server configured on 127.0.0.1 and port 53:
|
||||||
|
|
||||||
|
c := new(dns.Client)
|
||||||
|
in, rtt, err := c.Exchange(m1, "127.0.0.1:53")
|
||||||
|
|
||||||
|
Suppressing multiple outstanding queries (with the same question, type and
|
||||||
|
class) is as easy as setting:
|
||||||
|
|
||||||
|
c.SingleInflight = true
|
||||||
|
|
||||||
|
If these "advanced" features are not needed, a simple UDP query can be send,
|
||||||
|
with:
|
||||||
|
|
||||||
|
in, err := dns.Exchange(m1, "127.0.0.1:53")
|
||||||
|
|
||||||
|
When this functions returns you will get dns message. A dns message consists
|
||||||
|
out of four sections.
|
||||||
|
The question section: in.Question, the answer section: in.Answer,
|
||||||
|
the authority section: in.Ns and the additional section: in.Extra.
|
||||||
|
|
||||||
|
Each of these sections (except the Question section) contain a []RR. Basic
|
||||||
|
use pattern for accessing the rdata of a TXT RR as the first RR in
|
||||||
|
the Answer section:
|
||||||
|
|
||||||
|
if t, ok := in.Answer[0].(*dns.TXT); ok {
|
||||||
|
// do something with t.Txt
|
||||||
|
}
|
||||||
|
|
||||||
|
Domain Name and TXT Character String Representations
|
||||||
|
|
||||||
|
Both domain names and TXT character strings are converted to presentation
|
||||||
|
form both when unpacked and when converted to strings.
|
||||||
|
|
||||||
|
For TXT character strings, tabs, carriage returns and line feeds will be
|
||||||
|
converted to \t, \r and \n respectively. Back slashes and quotations marks
|
||||||
|
will be escaped. Bytes below 32 and above 127 will be converted to \DDD
|
||||||
|
form.
|
||||||
|
|
||||||
|
For domain names, in addition to the above rules brackets, periods,
|
||||||
|
spaces, semicolons and the at symbol are escaped.
|
||||||
|
|
||||||
|
DNSSEC
|
||||||
|
|
||||||
|
DNSSEC (DNS Security Extension) adds a layer of security to the DNS. It
|
||||||
|
uses public key cryptography to sign resource records. The
|
||||||
|
public keys are stored in DNSKEY records and the signatures in RRSIG records.
|
||||||
|
|
||||||
|
Requesting DNSSEC information for a zone is done by adding the DO (DNSSEC OK) bit
|
||||||
|
to a request.
|
||||||
|
|
||||||
|
m := new(dns.Msg)
|
||||||
|
m.SetEdns0(4096, true)
|
||||||
|
|
||||||
|
Signature generation, signature verification and key generation are all supported.
|
||||||
|
|
||||||
|
DYNAMIC UPDATES
|
||||||
|
|
||||||
|
Dynamic updates reuses the DNS message format, but renames three of
|
||||||
|
the sections. Question is Zone, Answer is Prerequisite, Authority is
|
||||||
|
Update, only the Additional is not renamed. See RFC 2136 for the gory details.
|
||||||
|
|
||||||
|
You can set a rather complex set of rules for the existence of absence of
|
||||||
|
certain resource records or names in a zone to specify if resource records
|
||||||
|
should be added or removed. The table from RFC 2136 supplemented with the Go
|
||||||
|
DNS function shows which functions exist to specify the prerequisites.
|
||||||
|
|
||||||
|
3.2.4 - Table Of Metavalues Used In Prerequisite Section
|
||||||
|
|
||||||
|
CLASS TYPE RDATA Meaning Function
|
||||||
|
--------------------------------------------------------------
|
||||||
|
ANY ANY empty Name is in use dns.NameUsed
|
||||||
|
ANY rrset empty RRset exists (value indep) dns.RRsetUsed
|
||||||
|
NONE ANY empty Name is not in use dns.NameNotUsed
|
||||||
|
NONE rrset empty RRset does not exist dns.RRsetNotUsed
|
||||||
|
zone rrset rr RRset exists (value dep) dns.Used
|
||||||
|
|
||||||
|
The prerequisite section can also be left empty.
|
||||||
|
If you have decided on the prerequisites you can tell what RRs should
|
||||||
|
be added or deleted. The next table shows the options you have and
|
||||||
|
what functions to call.
|
||||||
|
|
||||||
|
3.4.2.6 - Table Of Metavalues Used In Update Section
|
||||||
|
|
||||||
|
CLASS TYPE RDATA Meaning Function
|
||||||
|
---------------------------------------------------------------
|
||||||
|
ANY ANY empty Delete all RRsets from name dns.RemoveName
|
||||||
|
ANY rrset empty Delete an RRset dns.RemoveRRset
|
||||||
|
NONE rrset rr Delete an RR from RRset dns.Remove
|
||||||
|
zone rrset rr Add to an RRset dns.Insert
|
||||||
|
|
||||||
|
TRANSACTION SIGNATURE
|
||||||
|
|
||||||
|
An TSIG or transaction signature adds a HMAC TSIG record to each message sent.
|
||||||
|
The supported algorithms include: HmacMD5, HmacSHA1, HmacSHA256 and HmacSHA512.
|
||||||
|
|
||||||
|
Basic use pattern when querying with a TSIG name "axfr." (note that these key names
|
||||||
|
must be fully qualified - as they are domain names) and the base64 secret
|
||||||
|
"so6ZGir4GPAqINNh9U5c3A==":
|
||||||
|
|
||||||
|
c := new(dns.Client)
|
||||||
|
c.TsigSecret = map[string]string{"axfr.": "so6ZGir4GPAqINNh9U5c3A=="}
|
||||||
|
m := new(dns.Msg)
|
||||||
|
m.SetQuestion("miek.nl.", dns.TypeMX)
|
||||||
|
m.SetTsig("axfr.", dns.HmacMD5, 300, time.Now().Unix())
|
||||||
|
...
|
||||||
|
// When sending the TSIG RR is calculated and filled in before sending
|
||||||
|
|
||||||
|
When requesting an zone transfer (almost all TSIG usage is when requesting zone transfers), with
|
||||||
|
TSIG, this is the basic use pattern. In this example we request an AXFR for
|
||||||
|
miek.nl. with TSIG key named "axfr." and secret "so6ZGir4GPAqINNh9U5c3A=="
|
||||||
|
and using the server 176.58.119.54:
|
||||||
|
|
||||||
|
t := new(dns.Transfer)
|
||||||
|
m := new(dns.Msg)
|
||||||
|
t.TsigSecret = map[string]string{"axfr.": "so6ZGir4GPAqINNh9U5c3A=="}
|
||||||
|
m.SetAxfr("miek.nl.")
|
||||||
|
m.SetTsig("axfr.", dns.HmacMD5, 300, time.Now().Unix())
|
||||||
|
c, err := t.In(m, "176.58.119.54:53")
|
||||||
|
for r := range c { ... }
|
||||||
|
|
||||||
|
You can now read the records from the transfer as they come in. Each envelope is checked with TSIG.
|
||||||
|
If something is not correct an error is returned.
|
||||||
|
|
||||||
|
Basic use pattern validating and replying to a message that has TSIG set.
|
||||||
|
|
||||||
|
server := &dns.Server{Addr: ":53", Net: "udp"}
|
||||||
|
server.TsigSecret = map[string]string{"axfr.": "so6ZGir4GPAqINNh9U5c3A=="}
|
||||||
|
go server.ListenAndServe()
|
||||||
|
dns.HandleFunc(".", handleRequest)
|
||||||
|
|
||||||
|
func handleRequest(w dns.ResponseWriter, r *dns.Msg) {
|
||||||
|
m := new(dns.Msg)
|
||||||
|
m.SetReply(r)
|
||||||
|
if r.IsTsig() != nil {
|
||||||
|
if w.TsigStatus() == nil {
|
||||||
|
// *Msg r has an TSIG record and it was validated
|
||||||
|
m.SetTsig("axfr.", dns.HmacMD5, 300, time.Now().Unix())
|
||||||
|
} else {
|
||||||
|
// *Msg r has an TSIG records and it was not valided
|
||||||
|
}
|
||||||
|
}
|
||||||
|
w.WriteMsg(m)
|
||||||
|
}
|
||||||
|
|
||||||
|
PRIVATE RRS
|
||||||
|
|
||||||
|
RFC 6895 sets aside a range of type codes for private use. This range
|
||||||
|
is 65,280 - 65,534 (0xFF00 - 0xFFFE). When experimenting with new Resource Records these
|
||||||
|
can be used, before requesting an official type code from IANA.
|
||||||
|
|
||||||
|
see http://miek.nl/2014/September/21/idn-and-private-rr-in-go-dns/ for more
|
||||||
|
information.
|
||||||
|
|
||||||
|
EDNS0
|
||||||
|
|
||||||
|
EDNS0 is an extension mechanism for the DNS defined in RFC 2671 and updated
|
||||||
|
by RFC 6891. It defines an new RR type, the OPT RR, which is then completely
|
||||||
|
abused.
|
||||||
|
Basic use pattern for creating an (empty) OPT RR:
|
||||||
|
|
||||||
|
o := new(dns.OPT)
|
||||||
|
o.Hdr.Name = "." // MUST be the root zone, per definition.
|
||||||
|
o.Hdr.Rrtype = dns.TypeOPT
|
||||||
|
|
||||||
|
The rdata of an OPT RR consists out of a slice of EDNS0 (RFC 6891)
|
||||||
|
interfaces. Currently only a few have been standardized: EDNS0_NSID
|
||||||
|
(RFC 5001) and EDNS0_SUBNET (draft-vandergaast-edns-client-subnet-02). Note
|
||||||
|
that these options may be combined in an OPT RR.
|
||||||
|
Basic use pattern for a server to check if (and which) options are set:
|
||||||
|
|
||||||
|
// o is a dns.OPT
|
||||||
|
for _, s := range o.Option {
|
||||||
|
switch e := s.(type) {
|
||||||
|
case *dns.EDNS0_NSID:
|
||||||
|
// do stuff with e.Nsid
|
||||||
|
case *dns.EDNS0_SUBNET:
|
||||||
|
// access e.Family, e.Address, etc.
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
SIG(0)
|
||||||
|
|
||||||
|
From RFC 2931:
|
||||||
|
|
||||||
|
SIG(0) provides protection for DNS transactions and requests ....
|
||||||
|
... protection for glue records, DNS requests, protection for message headers
|
||||||
|
on requests and responses, and protection of the overall integrity of a response.
|
||||||
|
|
||||||
|
It works like TSIG, except that SIG(0) uses public key cryptography, instead of the shared
|
||||||
|
secret approach in TSIG.
|
||||||
|
Supported algorithms: DSA, ECDSAP256SHA256, ECDSAP384SHA384, RSASHA1, RSASHA256 and
|
||||||
|
RSASHA512.
|
||||||
|
|
||||||
|
Signing subsequent messages in multi-message sessions is not implemented.

# mapstructure
|
|
||||||
|
|
||||||
mapstructure is a Go library for decoding generic map values to structures
|
|
||||||
and vice versa, while providing helpful error handling.
|
|
||||||
|
|
||||||
This library is most useful when decoding values from some data stream (JSON,
|
|
||||||
Gob, etc.) where you don't _quite_ know the structure of the underlying data
|
|
||||||
until you read a part of it. You can therefore read a `map[string]interface{}`
|
|
||||||
and use this library to decode it into the proper underlying native Go
|
|
||||||
structure.
|
|
||||||
|
|
||||||
## Installation
|
|
||||||
|
|
||||||
Standard `go get`:
|
|
||||||
|
|
||||||
```
|
|
||||||
$ go get github.com/mitchellh/mapstructure
|
|
||||||
```
|
|
||||||
|
|
||||||
## Usage & Example
|
|
||||||
|
|
||||||
For usage and examples see the [Godoc](http://godoc.org/github.com/mitchellh/mapstructure).
|
|
||||||
|
|
||||||
The `Decode` function has examples associated with it there.
|
|
||||||
|
|
||||||
## But Why?!
|
|
||||||
|
|
||||||
Go offers fantastic standard libraries for decoding formats such as JSON.
|
|
||||||
The standard method is to have a struct pre-created, and populate that struct
|
|
||||||
from the bytes of the encoded format. This is great, but the problem is if
|
|
||||||
you have configuration or an encoding that changes slightly depending on
|
|
||||||
specific fields. For example, consider this JSON:
|
|
||||||
|
|
||||||
```json
|
|
||||||
{
|
|
||||||
"type": "person",
|
|
||||||
"name": "Mitchell"
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Perhaps we can't populate a specific structure without first reading
|
|
||||||
the "type" field from the JSON. We could always do two passes over the
|
|
||||||
decoding of the JSON (reading the "type" first, and the rest later).
|
|
||||||
However, it is much simpler to just decode this into a `map[string]interface{}`
|
|
||||||
structure, read the "type" key, then use something like this library
|
|
||||||
to decode it into the proper structure.
