[MirageOS-devel] Updating TROVE or maintaining a remote

[Anil Madhavapeddy <anil@xxxxxxxxxx>]

Hi all,

Christophe Troestler and Amir have been working on some infrastructure to make 
it easier to manage the growing number of distributed MirageOS repositories.  
These not only include the core libraries, but also the essential 
community-driven ones that aren't directly MirageOS-related but are still core 
(like Lwt, or Daniel Buenzli's many libraries, or Rump kernel), and then 
higher-level efforts like the TLS stack or the very new CCM-encrypted block 
storage [1].

So to drive these scripts, we need some metadata to get the list of 
repositories.  We currently use the TROVE [2] file to keep track, but this is 
always a little incomplete, and doesn't distinguish between the sorts of 
repositories.

My proposal is to maintain all of this metadata within OPAM.  We already have a 
"org:mirage" tag for many of the repositories, and it's possible to query the 
"dev-repo" field to get the raw Git repository from there.  What is missing is:

- an OPAM remote that we maintain with all the unreleased packages (like the 
ongoing ones for networking by Mindy, Jitsu by Magnus, autoscaling by 
Mort/Masoud and so on).  This would only be used for metadata purposes.

- Add additional tags to make it easier to filter these repositories.  I'm open 
to what these should be, but something task-oriented is probably most useful.  
e.g. mirage-net2 for the reworked network stack, or mirage-irmin for any 
storage related activities).

- Build a dashboard view of issues, commits and so on from the aggregation of 
this. Christophe is currently working on this, and I'm keen to add issue 
tracking to make releases and standardised labelling of issues in GitHub 
easier.  Once David Sheets finishes up the next iteration of Codoc, we can also 
generate cross-referenced documentation.

Any thoughts on this?  Christophe is working on this infrastructure right now, 
and we're keen to get something up and running in August.  I'm particularly 
interested in missing workflow features that would make your life easier as 
MirageOS developers and users.
