Add inotify support for monitoring conf dir to upload files

quote from: https://dominik.honnef.co/posts/2015/06/statically_compiled_go_programs__always__even_with_cgo__using_musl/

The second solution, which most people go for, is to avoid cgo altogether. They use the netgo tag to build a pure-Go version of the net package, and they set CGO_ENABLED=0. Of course this has the drawback of not being able to use cgo. That means you can’t even use os/user to get the name of the current user.

remove dependency on glibc for this tool?

Mac can't install etcdtool through brew, why do I need a github account and password to install it, and I can't use my own github account and password

Hi,

Are there any plans for supporting etcd v3?

Kind regards,
Peter

Environment

macOS Mojave 10.14.6
go 1.13.1

Here is the output I got when I ran brew install etcdtool :

Importing json with an empty directory skips that directory. For example, importing the following json:

{"empty_dir":{},"dir":{"key":"value"}}

results in:

/
└── dir/
    └── key

I thought this might be related to matching Go's default value if a dir is unmarshalled into an empty map, but I'm not sure because keys with empty string values are imported correctly.

Currently resume is only offered as a choice when running the same command again and there is a cached file.

When doing an import with --replace --yes, you still get asked if you want to overwrite. Looking at the code, I can't tell if this is intentional or an oversight. I can override this behavior by piping the word "yes" to the program, but I think that it would make more sense for --yes to "Answer yes to any questions".

Context: goal is to store files representing specific directories in git, going through PR review process, and on change, commit those to etcd.

When I try to import a YAML into etcd, the imported content is broken.
Digging into the code, I have found that the problem lies in etcdmap.Create.

It seems, json and toml return some sort of map[string]interface{} whereas yaml returns a map[interface{}]interface{}. This is causing a lot of trouble and an issue has been opened for go-yaml (see go-yaml/yaml#139, someone posted a workaround for this)

Here is an example that shows the problem:

package main

import (
  "fmt"
  "reflect"
  "encoding/json"
  "gopkg.in/yaml.v2"
)

func test(doc interface{}) {
  fmt.Println(doc)
  v := reflect.ValueOf(doc)
  fmt.Printf("Kind: %v\n", v.Kind())
  for _, k := range v.MapKeys() {
    fmt.Println(k.String())
  }
}


func main() {

  var doc interface{}

  fmt.Println("=== YAML ===")
  yaml.Unmarshal([]byte("a: b"), &doc)
  test(doc)

  fmt.Println("=== JSON ===")
  json.Unmarshal([]byte(`{"a":"b"}`), &doc)
  test(doc)
}

Run this and you should see:

=== YAML ===
map[a:b]
Kind: map
<interface {} Value>     <===== !!!!
=== JSON ===
map[a:b]
Kind: map
a

Like:

{
    "ntp": {
        "$ref": "etcd://etcd1.example.com:5001/#/schemas/ntp"
    }
}

[
    { "username": "jblack", "first_name": "John", "last_name": "Blackbeard" },
    { "username": "ltrier", "first_name": "Lars", "last_name": "Von Trier" }
]

This will now generate:

json: cannot unmarshal array into Go value of type map[string]interface {}

Hi there!

I'm facing a problem trying to import/export some data into etcd using etcdtool. Since lists are converted into json objects creating directories using the index as the key, when I load a json file with a list and then try to export the destination key, both json files differ.

Example:

# cat test.json 
{
  "mylist": [
    { "one": "uno"},
    {"two": "dos"}
  ]
}
# ./etcdtool-3.4 --peers="https://myetcd:2379" import -y /test ./test.json
# ./etcdtool-3.4 --peers="https://myetcd:2379" export /test
{
  "mylist": {
    "0": {
      "one": "uno"
    },
    "1": {
      "two": "dos"
    }
  }
}

It would be great to export the directory so the resulting json file is the same that was loaded (expected behavior: when all the keys in a directory are whole numbers, then convert them into a list). Maybe it can be added as an optional parameter (e.g. --keep-lists)?.

step1: I run git clone pull code and cd etcdtool

step2: I run make

mkdir build || true

We would love to use this tool programmatically, but running into issues with passing the password. Would you be open to a PR that added support for using a flag or environment variables or something else? I'm willing to work on it, just wanted to get your thoughts on the best strategy.

Thanks!

Create missing directories on import, maybe -create switch.

• Major cleanup and normalization of code

I noticed the latest released version 3.3.2 doesn't have the fix made here: #20 So I'm attempting to build my own RPM - Following the instructions doesn't seem to work:

[jlang1@antman etcdtool]$ make rpm
docker pull mickep76/centos-golang:latest
Trying to pull repository docker.io/mickep76/centos-golang ...
latest: Pulling from docker.io/mickep76/centos-golang

make: *** No rule to make target `make'. Stop.
make: *** [rpm] Error 2

Alternatively, if you could build a 3.4 RPM and "release it" I'd be happy with that too :)

Unfortunately tool cannot be built any more, because it is referring to a package which is not available any more:
github.com/mickep76/iodatafmt

I understood, the successor of this github repo would be
github.com/mickep76/encoding

But how to change that in the source code, that package is building again?
