Hi all,
I've had this thought and email in mind for a while, so I think it's time for me to write out some thoughts. I think there is a difference in the command line tools today from what I had envisaged, to what they became.
Now of course, there are lots of reasons for this - Simon and Mark have done awesome work here, and the team picked up after my uhh ... "untimely eviction" we'll say, when I went through a lot of troubling personal issues. So you know, lots of <3 for the team being fantastic and patient with me despite my apparent insanity :)
So I think what happened is that because I didn't expect this, communication didn't happen, I didn't support everyone and didn't communicate what I had in mind. I'm basically going to take this one on myself.
What this has led to is a pretty different approach - where I took a task-oriented approach, Simon and Mark in the design of the new web-console have taken an attribute-setting approach. What does this mean?
Let's take replication as an example: I would have created the tools to look more like:
# Setup a first master
dsconf instance_a replication initialise-topology
# Join a second master, doing a re-init as needed and setting up replication managers etc.
dsconf instance_b replication join-as-master --master instance_a
# Join a third master ...
dsconf instance_c replication join-as-master --master instance_a
# Make sure the agreements between a-b-c are full mesh
dsconf instance_a relication ensure-agreement instance_b
dsconf instance_a relication ensure-agreement instance_c
...
This could have actually been a different tool like dsrepl or something which may even be more expressive, to coordinate replication as a topology rather than per-server focussed.
An attribute-setting approach though is more like (this is made up in my head, not reflective of current actual command, just for the point of ideological discussion):
dsconf instance_a changelog init
dsconf instance_a replication_manager create
dsconf instance_a replica init --rid=10
dsconf instance_b changelog init
dsconf instance_b replication_manager create
dsconf instance_a replica init --rid=11
dsconf instance_a replication_agreement create --to=instance_b
The point here - I have always wanted to make the tools abstract from the gory horrid details that exist in cn=config. Setting attributes by hand wasn't what I "envisaged". The goal of these tools was such that you never had to know about these attributes or objects at all.
Now, people can always go an edit cn=config, I'll never stop that. If someone wants to use ldapmodify to admin their server, absolutely go ahead. But if I use a cli tool like this, I want it to abstract toward tasks that help me get my job done. I don't want to be an expert in remembering every single attribute on cn=replica, I want to just have two servers replicate. (sorry to bash-on replication, it's just a good example of a task that is reasonable complex to configure).
For me this is hard emotionally, because I feel like lib389, and the ds* tools are really creations of my love and passion, to improve things in the ways I always wanted 389 to be as the product I want to use, and enjoy using. To make tooling that encapsulates all our amazing knowledge and experience inside of highly accessible commands. Which then leads me to be sad about how things turned out because it's not the way "I wanted" (again, I feel like this failure is my responsibility due to what happened last year, not the fault of anyone else - everyone else has done their absolute best).
I would propose to change this - but I feel we are now wedged on change by two things:
* Red Hat have documented these tools, and it's a big ask to get them to re-document everything.
* The cockpit console uses these tools in a special --json mode ( I would have created a dscockpit command that just handled the --json mode, rather than trying to make a tool do two jobs well.). This means rewriting cockpit integration ....
* Time - heaps of time has already gone into these tools now, can we really justify undoing all that effort for this?
Which is a bit why I'm writing this
- Should I stop my task-oriented-vision and complaining that I have been doing, and accept what we have today?
- Do we want to try and pivot to change based on the ideas I have?
- Do I build something in parallel to satisfy my selfish desires, and to supplement what we have?
I don't know. But I think it's important to have this discussion as a team, including our emotional investments, concerns, visions and desires so that we can choose whats best. It's not good if we are "in-fighting" over the things we are doing, that helps no one - and neither does people feeling like their work isn't appreciated or respected (and I'm worried I have come off as disrespectful, which I am sorry for). We should be unified in what we want to do and achieve.
So I'd appreciate advice here. What should I/we do? What do we want 389 to look like in the future from a user-experience perspective?
Thanks everyone,
