Nixery's previous landing page was an mdBook that was basically
unmaintained and full of incorrect information. It also duplicated
some things (like nix-1p) which actually live elsewhere.
This commit removes the mdBook completely and reduces it down to a
simple TVL-style landing page. The landing page has been checked in
in its entirety because Nixery is frequently cloned through josh
without the entirety of depot, however the page has been created by
building it through depot's //web/tvl/template.

Upstream nixpkgs removed a lot of aliases this time, so we needed to do
the following transformations. It's a real shame that aliases only
really become discoverable easily when they are removed.
* runCommandNoCC -> runCommand
* gmailieer -> lieer
We also need to work around the fact that home-manager hasn't catched
on to this rename.
* mysql -> mariadb
* pkgconfig -> pkg-config
This also affects our Nix fork which needs to be bumped.
* prometheus_client -> prometheus-client
* rxvt_unicode -> rxvt-unicode-unwrapped
* nix-review -> nixpkgs-review
* oauth2_proxy -> oauth2-proxy
Additionally, some Go-related builders decided to drop support for
passing the sha256 hash in directly, so we need to use the generic hash
arguments.

Remove a race condition which appears when uploadHashLayer is called
with the same key from multiple threads simultaneously. This can
easily happen when the same image path is requested by multiple
clients at the same time. When it does, a 500 status is returned and
the following error message is logged:
{
"context": {
"filePath": "github.com/google/nixery/builder/builder.go",
"lineNumber": 440,
"functionName": "github.com/google/nixery/builder.uploadHashLayer"
},
"error": "rename /var/lib/nixery/staging/<hash> /var/lib/nixery/layers/<hash>: no such file or directory",
"eventTime": "...",
"layer": "<hash>",
"message": "failed to move layer from staging",
...
}
To solve this issue, introduce a mutex keyed on the uploaded hash and
move all layer caching into uploadHashLayer. This could additionally
provide a small performance benefit when an already built image is
requested and NIXERY_PKGS_PATH is set, since symlink layers and config
layers are now also cached.

Since the source of nix-1p is checked in under //nix/nix-1p, we should
use it from there if Nixery is being built inside of depot.

People occasionally ask what the current nixpkgs commit is on
nixery.dev (see e.g. https://github.com/tazjin/nixery/issues/153).
With this change, the commit is displayed on nixery.dev if Nixery is
built for the TVL deployment.

This exports the `:/tools/nixery` subtree to Github automatically
after merges to `canon`.
Due to the way the project was imported this continues the existing
git history in the external repository.

Nixery is going to gain a new binary (used for building images without
a registry server); to prepare for this the server binary has moved to
cmd/server and the Nix build logic has been updated to wrap this
binary and set the required environment variables.

Cleans up a whole bunch of things I wanted to get out of the door
right away:
* depot internal references to //third_party/nixery have been replaced
with //tools/nixery
* cleaned up files from Github
* fixed SPDX & Copyright headers
* code formatting and inclusion in //tools/depotfmt checks

This does not fully change the build structure of Nixery to be
depot-compatible yet, but should allow most targets to be built in
depot CI.
This contains some hacks to work around surface incompatibilities
which we'll clear away later.

This absorbs a josh-filtered Nix subtree into depot, at
//tools/nixery.
This subtree was created through `josh-filter ':prefix=tools/nixery'`,
which allows a filter on tools/nixery to yield the same commit hashes
as the original Nixery repository (allowing for history continuity).

Result of 'go get -u && go mod tidy'
|
|
Required for builds where the full repository isn't available (e.g.
from a tarball).
|
|
After the discussion in #116, this stores the blob content types
in extended attributes when using the filesystem backend.
If the underlying filesystem doesn't support extended attributes,
storing blobs won't work; also, if extended attributes get removed,
blobs won't be served anymore. We can relax this behavior if
needed (i.e. log errors but still accept to store or serve blobs).
However, since the Docker Engine (and possibly other container
engines) won't accept to pull images from a registry that doesn't
use correct content types for manifest files, it could be argued
that it's better to give a hard fail. (Otherwise, the container
engine gives cryptic error messages like "missing signature key".)
I can change that behavior (and log errors but still store/serve
blobs to the filesystem) if you think it's better.

Drops the go2nix configuration in favour of pkgs.buildGoModule.
Note that the go.sum file is bloated by issues with cyclic
dependencies in some Google projects, but this large number of
dependencies is not actually built.
|
|
|
|
This moves the pin from just being in the Travis configuration to also
being set in a nixpkgs-pin.nix file, which makes it trivial to build
at the right commit when performing local builds.
|
|
This gets rid of the package called "server" and instead moves
everything into the project root, such that Go actually builds us a
binary called `nixery`.
This is the first step towards factoring out CLI-based functionality
for Nixery.
|
|
Nixery itself is built with the buildLayeredImage system, which takes
some time to create large numbers of layers.
This adjusts the default number of image layers from 96 to 20.
Additionally Nixery's image is often loaded with `docker load -i`,
which ignores layer cache hits anyways.
Additionaly the CI build is configured to use only 1, which speeds up
CI runs.
|
|
|
|
In most cases this is not useful for users without the wrapper script,
so users should always build nixery-bin anyways.
|
|
Some Nix download mechanisms will add a second hash in the store path,
which had been added to the source hash output (breaking argument
interpolation).
|
|
Uses a hash of Nixery's sources as the version displayed when Nixery
launches or logs an error. This makes it possible to distinguish
between errors logged from different versions.
The source hashes should be reproducible between different checkouts
of the same source tree.
|
|
With these changes it is possible to keep Nixery in $GOPATH and build
the server in there, while still having things work correctly via Nix.
|
|
This functionality has been rolled into the server component and is no
longer required.
|
|
|
|
This introduces a new Nix derivation that, given an attribute set of
layer hashes mapped to store paths, will create a layer tarball for
each of the store paths.
This is going to be used by the builder to create layers that are not
present in the cache.
Relates to #50.
|
|
Simplifies the wrapper script used to invoke Nix builds from Nixery to
just contain the essentials, since the layer grouping logic is moving
into the server itself.
|
|
This makes CI build the group-layers tool (and cache it to Cachix!)
|
|
Fixes two launch script compatibility issues with other container
runtimes (such as gvisor):
* don't fail if /tmp already exists
* don't fail if the environment becomes unset
|
|
This is useful when running Nixery locally.
|
|
Introduces three new types representing each of the possible package
sources and moves the logic for specifying the package source to the
server.
Concrete changes:
* Determining whether a specified git reference is a commit vs. a
branch/tag is now done in the server, and is done more precisely by
using a regular expression.
* Package sources now have a new `CacheKey` function which can be used
to retrieve a key under which a build manifest can be cached *if*
the package source is not a moving target (i.e. a full git commit
hash of either nixpkgs or a private repository).
This function is not yet used.
* Users *must* now specify a package source, Nixery no longer defaults
to anything and will fail to launch if no source is configured.
|
|
This package is used by a variety of programs that users may want to
embed into Nixery in addition, for example cachix, but those packages
don't refer to it explicitly.
|
|
This makes it possible to inject additional programs (e.g. Cachix)
into a Nixery container.
|
|
This is required by git in cases where Nixery is configured with a
custom git repository.
I've also added a shell back into the image to make debugging a
running Nixery easier. It turns out some of the dependencies already
pull in bash anyways, so this is just surfacing it to $PATH.
|
|
Some upcoming changes might require the Nix build to be split into
multiple separate nix-build invocations of different expressions, thus
splitting this out is useful.
It also fixes an issue where `build-image/default.nix` might be called
in an environment where no Nix channels are configured.
|
|
ALl the ones except for build-image.nix are considered trivial. On the
latter, nixfmt makes some useful changes but by-and-large it is not
ready for that code yet.
|
|
The issue is described in detail in a comment in
`build-image/default.nix`, please read it.
|
|
Instead of requiring the server component to be made aware of the
location of the Nix builder via environment variables, this commit
introduces a wrapper script for the builder that can simply exist on
the builders $PATH.
This is one step towards a slightly nicer out-of-the-box experience
when using `nix-build -A nixery-bin`.
|
|
|
|
|
|
This uses a significantly larger percentage of the total available
layers (125) than before, which means that cache hits for layers
become more likely between images.
|
|
Executes the previously added mdBook on the previously added book
source to yield a directory that can be served by Nixery on its index
page.
This is one of those 'I <3 Nix' things due to how easy it is to do.
|
|
Upstream nixpkgs currently only has an older versin of mdBook. Until
that changes, we keep a different version in here.
|
|
This makes it possible for users to hook basically arbitrary things
into the Nixery container image.
|
|
Shiny, new domain is much better and eliminates the TLS redirect issue
because there is a HSTS preload for the entire .dev TLD (which, by the
way, is awesome!)
|

Mea culpa!
