QUESTION

Using a particular version for golang dependency module

Asked 2021-Apr-19 at 04:38

I'm trying to build postfix-exporter code from the github link. It has a dependency on the go-systemd package as mentioned in go.mod file github.com/coreos/go-systemd/v22 v22.0.0. I see in the go.mod file , the mentioned version for the package is v22.0.0. But when I run go get -u for this path, it starts downloading the latest version ( v22.2.0) of go-systemd which has an issue in the latest commit and causing failure to compile . The error coming in that is

Don't use -u. The purpose of -u is to allow Go to try to upgrade you to the latest minor or patch version:

The -u flag instructs get to update modules providing dependencies of packages named on the command line to use newer minor or patch releases when available.

If you're just trying to install dependencies, use go get.

Its a bug with version inconsistency between go-micro and grpc. About a week ago I tried to follow the tutorial which you mention and got same error. If you want to fix the error above please follow the interactions below the link: https://github.com/etcd-io/etcd/issues/11563.

In additionally I recommend you just build grpc service without go-micro, due to version inconsistency.

QUESTION

Go build, with module, fails under an Alpine image but is fine under Windows

Asked 2019-Nov-22 at 17:04

I was running a small test to connect to ETCD. This test imports go.etcd.io/etcd/clientv3 witch, by the magic of go modules, pulls github.com/coreos/go-systemd/journal.

I use go module to manage the dependencies.

First I ran my test under windows with go version go1.13.1 windows/amd64 and everything is fine and works well as expected.

After that because my etcd client project is intended to be deploy via a Docker image, based on alpine, I tried to compile it with the go 1.13 image golang:1.13-alpine

I used :

The problem is go.etcd.io/etcd depends on github.com/coreos/go-systemd/journal on linux, which is not using go modules correctly. There are two issues (#321 and #325) submitted to the project and the maintainer acknowledge the problem (but not solved it yet).

The solution suggested there is to add the following to go.mod:

QUESTION

Is it possible to sort maps for real?

Asked 2019-Nov-08 at 09:05

I know the creators of Go decided to randomize the keys of maps so that people didn't assume their order. I guess that could have changed by now but I haven't seen any documentation to that effect.

There's a call to a Linux journal function as follows:

You would need to use a thrid-party library like emirpasic/gods, which does implement:

TreeMap: A map based on red-black tree. Keys are ordered with respect to the comparator.
Linked Hashmap: A map that preserves insertion-order. It is backed by a hash table to store values and doubly-linked list to store ordering.

But Map alone would remain with randomize keys order.

After contacting Google I have figured out what the issue is.

The issue is a combination of an error character limit of 4096 characters in Google Cloud Functions wrapper and an artificial timeout for go mod downloads imposed by Google.

The issue can be resolved by vendoring your dependencies as explained here: https://cloud.google.com/functions/docs/writing/specifying-dependencies-go#using_a_vendor_directory

QUESTION

How do I register for systemd service lifecycle events?

Asked 2017-Aug-04 at 20:01

I want to be informed about all state changes of service units. I know there is the DBUS API which gives me signals for UnitNew and UnitRemoved, but the semantic is still unclear to me. Also the signals doesn't provide the informations I need.

I'm using go and tried the go-systemd lib from coreos. They provide a way to "subscribe" but it's in fact polling all the unit information available in the system. I do not want to do so every few milliseconds, just to get informed about statechanges.

I also tried the default org.freedesktop.DBus.Properties but I can not get this working.

Please help If you can, I'm out of ideas.

The systemd APIs that contain information about the start or stop of service units are:

The systemd journal. You can listen to it by executing journalctl or forwarding it via network to your program or watching for changes to the files on disk. E.g.: execute journalctl --follow -o json-pretty _PID=1 (you can add various filters like UNIT=gdm.service to only get those for one service) and then parse stdout according to the systemd journal json output format to get the journal messages of systemd. Use the MESSAGE_ID to match what the event means and watch for unknown messages to know when an existing message got replaced with a new one. While this might work robustly enough, log messages are not primarily intended as an API. As such I would recommend to use the below options.
Linux cgroup notifications as they get generated when systemd uses cgroups to start a service.
systemd units via their dependencies (like Wants=)
