docs: Add old release notes
These release notes used to live on the mailing list at: https://listman.redhat.com/archives/mgmtconfig-list/ until Red Hat killed off this excellent service recently. I'm adding them all here for reference. Before 0.0.9 there were no release notes.

|
||||
This is a huge and hugely important release! It has been a long time
|
||||
coming. We have lambdas! I could not have done this without the
|
||||
unrelentingly supportive and brilliant Samuel Gélineau.
|
||||
|
||||
Getting past the blockers and tricky code changes was all thanks to
|
||||
him. Cleanups, polish and making it more golang idiomatic was my doing.
|
||||
(The easy stuff.) If Sam wanted to be a golang expert, he could have
|
||||
done it all, but it was more sensible than I do all the mundane and
|
||||
filler stuff.
|
||||
|
||||
With that, here are a few highlights from the release:
|
||||
|
||||
* We have working lambdas, including iter.map =D
|
||||
|
||||
* We have a new function engine!
|
||||
|
||||
* We have improved type unification!
|
||||
|
||||
* We have an improved resource engine!
|
||||
|
||||
* We have improved many of the internal API's.
|
||||
|
||||
* We have so many tests.
|
||||
|
||||
And much more...

|
||||
|
||||
NEWS
|
||||
|
||||
* Our main tests are now in the excellent .txtar format. This makes
|
||||
things much easier to manage.
|
||||
|
||||
* The iter.map function can be named as such due to parser tricks! No
|
||||
need to name it xmap anymore!
|
||||
|
||||
* The unification solver has been greatly improved. We can infer a lot
|
||||
more about function types.
|
||||
|
||||
* The resources API uses the context package for closing Watch and
|
||||
returning early from CheckApply. The next step would be to remove all
|
||||
the resource-specific timeout code and make that a metaparam.
|
||||
|
||||
* A new sync primitive has been added in case you'd like to use it
|
||||
somewhere. We'd love help adding an even more complex one. Look in
|
||||
util/sync.go for more information.
|
||||
|
||||
* Sam added some beautiful type inference debugging that makes things
|
||||
easier for those familiar with the standard literature.
|
||||
|
||||
* An important bug in standalone etcd has been fixed. While embedded
|
||||
etcd and automatic clustering isn't "supported" (it's buggy) the
|
||||
status-quo of using your own etcd cluster is stable, and you can even
|
||||
use the embedded etcd server in standalone mode...
|
||||
|
||||
* This means you can run `mgmt etcd` and get the standard etcd binary
|
||||
behviour that you'd get from running `etcd` normally. This makes it
|
||||
easy to use both together since you only need to transport one binary
|
||||
around. (And maybe mgmt will do that for you!)
|
||||
|
||||
* I fixed and cleaned up some sketchy code in the resource engine. I
|
||||
had been unmotivated to fix this for a while because I really wanted
|
||||
lambdas first, but now that they are in, I took a good look at the
|
||||
code, made some fixes, and I'm really happy with it now.
|
||||
|
||||
* Metaparams are appropriately stateful between graph switches now.
|
||||
Retry is the easy example. Limit/Burst need to be ported if you care
|
||||
about these fine details.
|
||||
|
||||
* A RetryReset metaparam has been added. This is another good example
|
||||
of how powerful metaparams are and how much potential there is for
|
||||
building systems with these and future ones.
|
||||
|
||||
* A bunch of internal API's have been updated. This makes it better for
|
||||
function and resource writers! Some GAPI changes also got pushed
|
||||
through that make things clearer for those reading code.
|
||||
|
||||
* We have a listlookup function. It's still missing syntactic sugar
|
||||
though!
|
||||
|
||||
* Our new function graph engine is called "dage". I think it's pretty
|
||||
clever. There's a chance there is still a bug inside, but it's unclear.
|
||||
Please report any issues. If you have some large machines I can test
|
||||
very large and fast graphs on, please let me know.
|
||||
|
||||
* Lambdas really work now! The txn and ref/gc code is pretty fantastic.
|
||||
|
||||
* Many bugs have been killed!
|
||||
|
||||
* We're looking for help writing Amazon, Google, DigitalOcean, Hetzner,
|
||||
etc, resources if anyone is interested, reach out to us. Particularly
|
||||
if there is support from those organizations as well.
|
||||
|
||||
* Many other bug fixes, changes, etc...
|
||||
|
||||
* See the git log for more NEWS, and for anything notable I left out!
|
||||
|
||||
BUGS/TODO
|
||||
|
||||
* Function values getting _passed_ to resources doesn't work yet, but
|
||||
it's not a blocker, but it would definitely be useful. We're looking
|
||||
into it.
|
||||
|
||||
* Function graphs are unnecessarily dynamic. We might make them more
|
||||
static so that we don't need as many transactions. This is really a
|
||||
compiler optimization and not a bug, but it's something important we'd
|
||||
like to have.
|
||||
|
||||
* Running two Txn's during the same pause would be really helpful. I'm
|
||||
not sure how much of a performance improvement we'd get from this, but
|
||||
it would sure be interesting to build. If you want to build a fancy
|
||||
synchronization primitive, then let us know! Again this is not a bug.
|
||||
|
||||
TALKS
|
||||
|
||||
I don't have anything planned until CfgMgmtCamp 2024. If you'd like to
|
||||
book me for a private event, or sponsor my travel for your conference,
|
||||
please let me know.
|
||||
|
||||
