julia_15: nixpkgs unstable → 21.05

Apparently the working julia version was moved into a stable channel since I last looked at this, and the version in unstable is broken again. Fun! Anyways, it builds again now (as part of parsons's config)

 # hacc nixfiles

-Welcome to the hacc nixfiles (haccfiles). This is how we configure (most of)
-our infrastructure.
+welcome to hacc nixfiles (haccfiles). this is the code describing our nix-based infrastructure.

-## General layout
+## structure

- `flake.nix`: Entrypoint & dependencies
+- `default.nix`: Entrypoint to the config
+- `common/`: configuration common to all hosts
+- `desktop/`: desktop-relevant communication
 - `modules/`: home-grown modules for hacc-specific services
- `pkgs/`: packages we need which aren't in nixpkgs
- `websites/`: static websites hosted by us
- `common/`: meta-level config, reusable across machines
- `parsons/`: our sole server, its config & the services it runs
+- `nix/`: sources files, managed with niv
+- `pkgs/`: packages we built and don't want to upstream

-Right now, we only have a single host. We might add more again in the future.
+## working with the haccfiles

-## Working with this repo
-
-You will need a flake-enabled nix installation, and have your ssh config set up
-so that `ssh parsons` will connect to `parsons.hacc.space`.
-
-### Deploying remotely
-
-It's recommended to use [deploy_rs](https://github.com/serokell/deploy-rs):
-~~~shell
-deploy .#parsons -k [--dry-activate]
-~~~
-
-Alternatively, using just `nixos-rebuild`:
-~~~shell
-nixos-rebuild --flake .#parsons --target-host parsons \
-  --use-remote-sudo --use-substitutes [test|switch|dry-activate]
-~~~
-
-### Re-deploying on parsons itself
-
-Simply do:
-~~~shell
-nixos-rebuild --flake .#parsons [test|switch|dry-activate]
-~~~
-
-## Working on websites
-
-Websites are exposed as flake outputs: if you're working on a website & want to
-check it in a browser, do e.g.
-
-~~~shell
-nix run .#\"muc.hacc.earth\"
-~~~
-
-to start a local http server (note that some of our websites need a directory
-to be built in; these use `/tmp/hacc-website`).
-
-To add a new website, add a new subdirectory to `websites`; nix will generate a
-vhost config based on that directory's name. Add a `default.nix` in your directory
-describing how to build the website, and give its derivation a `watch` attribute
-to make the `nix run` setup work.
-
-## I don't want to build this long dependency / want a cached version!
-
-If it's still available on parsons from a previous deploy, do:
-```shell
-nix copy --from ssh://parsons /nix/store/...
+deploy:
+``` shell
+nix build -f . deploy.$hostname && ./result switch
 ```

-Note: don't just copy the .drv file (which Nix complains about if it can't
-build something), that's just the description of how to build it! If you
-don't know the actual outpath, look in the .drv file (should start with
-`Derive([("out","[the path you want]"...`)
+`$hostname` can be replaced with any hostname or group

 ## committing to haccfiles
- Things on `main` should always reflect the config that's actually deployed on
-  parsons, except during testing / debugging sessions
+- Golden Rule: DO NOT COMMIT TO MAIN
+  - exceptions apply, if you are not sure where to commit, don't commit to main
 - split up commits, every commit is one atomic change
- follow the commit format: "place: $change"
-  - place: e.g. `modules/$module`, `services/$service` ...
-  - change: describe your change. Please wrap your lines sensibly (or configure
-    your editor to do this for you)
+  - e.g. no big "did some changes" but instead "updated service x", "updated service y", "update service z"
+- follow the commit format: "$prefix$place: $change"
+  - prefix: one of fixup, nothing
+  - place: one of "modules/$module", "$hostname/service", "common/($place)", "pkgs/$pkgs" or "sources"
+  - change: describe your change, don't go over the character limit where git starts hiding/wrapping
 - Exception: autogenerated messages (merge commits, reverts, etc)
- don't overuse merge commits, try to rebase things if possible with reasonable
-  effort

-## Secret management
-
-We use [sops-nix](https://github.com/Mic92/sops-nix) to manage secrets which we'd
-like to have in Git but don't want to be public. Entries in `secrets.yaml` are
-encrypted for each of the age keys listed in `.sops.yaml`, which are themselves
-derived from ssh keys.
-
-For the initial set up, please take a look at the sops-nix Readme file.
-
-To edit the secrets file, run `sops secrets.yaml`, which will decrypt the
-file & open it in your $EDITOR, then re-encrypt it when you're done.
-
-To add a new key, use `ssh-to-age` to convert your ssh key to age, and add it to
-`sops.yaml`. Then do `sops updatekeys secrets.yaml` to re-encrypt the file for
-the new set of keys.

-hegedoc was once called codiMD, so container, config and users are still called codimd.
-
-**Do NOT change this** unless you're sure what you're doing.
-
-We have two instances:
- - `pad-hacc`/pad.hacc.space is connected to our SSO/uffd
- - `pad-i4f`/pad.infra4future.de is not connected to our SSO and meant to be more public
-
-## Basic Troubleshooting
-
-Usually if hedgedoc dies, it's because postgresql wasn't there yet. Just restart
-hedgedoc.
-
-## More Troubles
-log into the container and take a look at the logs
-
-~~~shell
-sudo nixos-container root-login codimd
-journalctl -e
-~~~
-
-### fixing failed database upgrades
-
-see https://docs.hedgedoc.org/guides/migration-troubleshooting/ (copied below
-for convenience?):
-
-In some cases, HedgeDoc might apply migrations without correctly saving the
-progress. It will then refuse to start with "already exists"-errors like
-ERROR: type "enum_Notes_permission" already exists.
-
-Get the name of the failing migration and append .js to it. For example, if
-you encounter this error:
-
-~~~
-== 20180306150303-fix-enum: migrating =======
-
-ERROR: type "enum_Notes_permission" already exists
-~~~
-
-the name of the failed migration would be 20180306150303-fix-enum.js.
-
-The SQL-statement may look like this:
-
-~~~
-INSERT INTO "SequelizeMeta" (name) VALUES ('20180306150303-fix-enum.js');
-~~~
-
-Make sure HedgeDoc does not run and insert the name into the SequelizeMeta table.
-Enter the container switch to the postgres user, open psql and commect to the
-codimd database:
-
-~~~shell
-su postgres
-psql
-\l
-\c codimd
-UN adjusted SQL STAMEMENT from above ]
-\q
-~~~
-
-Start HedgeDoc again and observe if it starts correctly. It may be necessary to
-repeat this process and insert multiple migrations into the SequelizeMeta table.

- choose a name (no aliases or other names can be the same)
- generate a sha-512 password hash ```mkpasswd -m sha-512``` - **never add an

- You can send mail as you and any alias you receive mail from. Set a second Identity in your e-mail client
-
-### as an application
- mailserver: `mail.hacc.space`
- Do **not** use port 25. It's for server to server communication only.
- Use smtp ports `587` or `465`
- enable TLS if possible
- only send mail from `noreply@infra4future.de`
- Password is somewhere (TODO!)

-Mumble's server is called murmur, but the naming is inconsistent. Sometimes
-it's also just called mumble server.
-
-# Usage
-
-## registration
-Users need to be registered to join any other channel than public.
-An already registered user has to register them with the server.
-1. right click on the username
-2. choose register in the menu. Done.
-
-## restricted channels
-Every channel in the hacc category except for plenum can only be accessed by
-members of the hacc group.
-
-## adding users to a group
-Only admins can edit groups, and only registered users can be added to groups.
-1. right click on the Root channel
-2. select Edit...
-2. In Groups select $groupname
-3. make the change you want to make
-4. click "OK"
-
-# Config details
- the server is not registered with mumble & not on the public server list 
- the bitrate is set to 128kb/s; otherwise the client would complain that the
-  server bitrate is less then the configured (default) in its local settings
-
-# Hacks
- murmur needs a TLS cert, which we get via the ACME module
- there's a funny group setup so that hopefully murmurd can read the cert
- this seems to work fine now, but was some source of trouble in the past

+#+TITLE: Pluto standalone
+
+This is a nix derivation that wraps a version of julia with the packages
+(and their dependency closure) defined in ~Packages.toml~; currently
+this is just Pluto. It also provides a little julia script that will
+activate this packageset (called a "julia depot"), and then start a
+Pluto notebook server on port 9999. Note that it does so without setting
+up any kind of authenticaton, so don't expose that port!
+
+* TODOs
+- [ ] add more packages
+- [ ] more sensible auth
+- [ ] working precompilation; this would probably allow running this
+  without a writable julia depot
+
+* Steps to reproduce / update the julia-to-nix part of this:
+
+In general, it is enough to follow the readme of julia2nix, but since
+that has a bunch of unstated assumptions and weird failure modes, here's a rough outline of how to actually do it:
+ - using julia's package managing mode, make changes to ~Packages.toml~
+   and ~Manifest.toml~. Be sure to use the same version of julia that
+   will run on hainich (currently the ~julia_15~ package of
+   nixpkgs-unstable), as otherwise hashes may be different
+ - clone https://github.com/thomasjm/julia2nix somewhere
+ - run ~julia2nix~ to generate the nix derivations
+   + unfortunately, jula2nix assumes that nixpkgs-unstable is available
+     as ~<nixpkgs>~ from within nix; it may fail if you are on another
+     channel. In that case, there seems to be no better solution than grepping for occurences of "<nixpkgs>" in jula2nix and replacing
+     them with some other path that has the required version
+   + this will re-generate all the ~*.nix~ files in this directory, and
+     probably reset all options. The defaults are reasonably sensible,
+     but make sure to disable the ~precompile~ option in ~default.nix~
+     (see below for why)
+ - run ~nix-build --no-out-link~ to check if it worked and nix can
+   build the julia depot
+ - deploy hainich. Note that the derivation will only contain the
+   package sources, not a compiled version. Julia will compile packages
+   on startup (and cache them for subsequent runs), so after the deploy
+   it may take a minute or two to actually run Pluto
+
+* precompilation
+/In theory/, we should be able to precompile all the packages during
+nix-build, and then directly load them into julia and runtime.
+However, this currently fails, and even if precompiled packages are
+present in the depot built via nix, julia will refuse to use them and
+recompile them instead (in a second julia depot that is writable at
+runtime).
+
+There's an open issue on this at jula2nix:

+   Usually refs are either tags (refs/tags/*) or branches (refs/heads/*)
+   Cloning branches will make the hash check fail when there is an update.
+   But not all patches we want can be accessed by tags.
+
+   The workaround is getting the last n commits so that it's likely that they
+   still contain the hash we want.
+
+   for now : increase depth iteratively (TODO)
+
+   real fix: ask git folks to add a
+   git fetch $HASH contained in $BRANCH
+   facility because checking that $HASH is contained in $BRANCH is less
+   expensive than fetching --depth $N.
+   Even if git folks implemented this feature soon it may take years until
