regnat e9b39f6004 Restrict the operations on drv outputs in recursive Nix 
There's currently no way to properly filter them, so disallow them
altogether instead.
 2020-12-11 21:17:25 +01:00
regnat bab1cda0e6 Use the hash modulo in the derivation outputs 
Rather than storing the derivation outputs as `drvPath!outputName` internally,
store them as `drvHashModulo!outputName` (or `outputHash!outputName` for
fixed-output derivations).

This makes the storage slightly more opaque, but enables an earlier
cutoff in cases where a fixed-output dependency changes (but keeps the
same output hash) − same as what we already do for input-addressed
derivations.

Fix #4332
 2020-12-11 21:05:09 +01:00
regnat 3ac9d74eb1 Rework the db schema for derivation outputs 
Add a new table for tracking the derivation output mappings.

We used to hijack the `DerivationOutputs` table for that, but (despite its
name), it isn't a really good fit:

- Its entries depend on the drv being a valid path, making it play badly with
  garbage collection and preventing us to copy a drv output without copying
  the whole drv closure too;
- It dosen't guaranty that the output path exists;

By using a different table, we can experiment with a different schema better
suited for tracking the output mappings of CA derivations.
(incidentally, this also fixes #4138)
 2020-12-11 20:41:32 +01:00
regnat 58cdab64ac Store metadata about drv outputs realisations 
For each known realisation, store:
- its output
- its output path

This comes with a set of needed changes:

- New `realisations` module declaring the types needed for describing
  these mappings
- New `Store::registerDrvOutput` method registering all the needed informations
  about a derivation output (also replaces `LocalStore::linkDeriverToPath`)
- new `Store::queryRealisation` method to retrieve the informations for a
  derivations

This introcudes some redundancy on the remote-store side between
`wopQueryDerivationOutputMap` and `wopQueryRealisation`.
However we might need to keep both (regardless of backwards compat)
because we sometimes need to get some infos for all the outputs of a
derivation (where `wopQueryDerivationOutputMap` is handy), but all the
stores can't implement it − because listing all the outputs of a
derivation isn't really possible for binary caches where the server
doesn't allow to list a directory.

libstore/openStore: fix stores with IPv6 addresses 
In `nixStable` (2.3.7 to be precise) it's possible to connect to stores
using an IPv6 address:

  nix ping-store --store ssh://root@2001:db8::1

This is also useful for `nixops(1)` where you could specify an IPv6
address in `deployment.targetHost`.

However, this behavior is broken on `nixUnstable` and fails with the
following error:

  $ nix store ping --store ssh://root@2001:db8::1
  don't know how to open Nix store 'ssh://root@2001:db8::1'

This happened because `openStore` from `libstore` uses the `parseURL`
function from `libfetchers` which expects a valid URL as defined in
RFC2732. However, this is unsupported by `ssh(1)`:

  $ nix store ping --store 'ssh://root@[2001:db8::1]'
  cannot connect to 'root@[2001:db8::1]'

This patch now allows both ways of specifying a store (`root@2001:db8::1`) and
also `root@[2001:db8::1]` since the latter one is useful to pass query
parameters to the remote store.

In order to achieve this, the following changes were made:

* The URL regex from `url-parts.hh` now allows an IPv6 address in the
  form `2001:db8::1` and also `[2001:db8::1]`.

* In `libstore`, a new function named `extractConnStr` ensures that a
  proper URL is passed to e.g. `ssh(1)`:

  * If a URL looks like either `[2001:db8::1]` or `root@[2001:db8::1]`,
    the brackets will be removed using a regex. No additional validation
    is done here as only strings parsed by `parseURL` are expected.

  * In any other case, the string will be left untouched.

* The rules above only apply for `LegacySSHStore` and `SSHStore` (a.k.a
  `ssh://` and `ssh-ng://`).

Unresolved questions:

* I'm not really sure whether we want to allow both variants of IPv6
  addresses in the URL parser. However it should be noted that both seem
  to be possible according to RFC2732:

  > This document incudes an update to the generic syntax for Uniform
  > Resource Identifiers defined in RFC 2396 [URL].  It defines a syntax
  > for IPv6 addresses and allows the use of "[" and "]" within a URI
  > explicitly for this reserved purpose.

* Currently, it's not supported to specify a port number behind the
  hostname, however it seems as this is not really supported by the URL
  parser. Hence, this is probably out of scope here.

regnat c87267c2a4 Store the final drv outputs in memory when building remotely 
The `DerivationGoal` has a variable storing the “final” derivation
output paths that is used (amongst other things) to fill the environment
for the post build hook. However this variable wasn't set when the
build-hook is used, causing a crash when both hooks are used together.

Fix this by setting this variable (from the informations in the db) after a run
of the post build hook.

exists locally which isn't the case for remote builders.

Matthew Bauer aa07502009 Always default to cache.nixos.org even when different nix store dir 
Since 0744f7f, it is now useful to have cache.nixos.org in substituers
even if /nix/store is not the Nix Store Dir. This can always be

Matthew Bauer 4b9acf4e21 Use posix_spawn_setbinpref_np to advise which architecture to run 
When running universal binaries like /bin/bash, Darwin XNU will choose
which architecture of the binary to use based on "binary preferences".
This change sets that to the current platform for aarch64 and x86_64
builds. In addition it now uses posix_spawn instead of the usual
execve. Note, that this does not prevent the other architecture from
being run, just advises which to use.

Unfortunately, posix_spawnattr_setbinpref_np does not appear to be
inherited by child processes in x86_64 Rosetta 2 translations, meaning
that this will not always work as expected.

For example:

  {
    arm = derivation {
      name = "test";
      system = "aarch64-darwin";
      builder = "/bin/bash";
      args = [ "-e" (builtins.toFile "test" ''
        set -x
        /usr/sbin/sysctl sysctl.proc_translated
        /usr/sbin/sysctl sysctl.proc_native
        [ "$(/usr/bin/arch)" = arm64 ]
        /usr/bin/touch $out
      '') ];
    };
    rosetta = derivation {
      name = "test";
      system = "x86_64-darwin";
      builder = "/bin/bash";
      args = [ "-e" (builtins.toFile "test" ''
        set -x
        /usr/sbin/sysctl sysctl.proc_translated
        /usr/sbin/sysctl sysctl.proc_native
        [ "$(/usr/bin/arch)" = i386 ]
        echo It works!
        /usr/bin/touch $out
      '') ];
    };
  }

`arm' fails on x86_64-compiled Nix, but `arm' and `rosetta' succeed on
aarch64-compiled Nix. I suspect there is a way to fix this since:

  $ /usr/bin/arch -arch x86_64 /bin/bash \
    -c '/usr/bin/arch -arch arm64e /bin/bash -c /usr/bin/arch'
  arm64

seems to work correctly. We may need to wait for Apple to update
system_cmds in opensource.apple.com to find out how though.

Matthew Bauer 9b1824ecbd Add extraPlatforms for Rosetta 2 macOS 
macOS systems with ARM64 can utilize a translation layer at
/Library/Apple/usr/libexec/oah to run x86_64 binaries. This change
makes Nix recognize that and it to "extra-platforms". Note that there
are two cases here since Nix could be built for either x86_64 or
aarch64. In either case, we can switch to the other architecture.
Unfortunately there is not a good way to prevent aarch64 binaries from
being run in x86_64 contexts or vice versa - programs can always
execute programs for the other architecture.

Jake Waksbaum 01db455733 Fix deadlock in nix-store when max-connections=1 
This fixes a bug I encountered where `nix-store -qR` will deadlock when
the `--include-outputs` flag is passed and `max-connections=1`.

The deadlock occurs because `RemoteStore::queryDerivationOutputs` takes
the only connection from the connection pool and uses it to check the
daemon version. If the version is new enough, it calls
`Store::queryDerivationOutputs`, which eventually calls
`RemoteStore::queryPartialDerivationOutputMap`, where we take another
connection from the connection pool to check the version again. Because
we still haven't released the connection from the caller, this waits for
a connection to be available, causing a deadlock.

This diff solves the issue by using `getProtocol` to check the protocol
version in the caller `RemoteStore::queryDerivationOutputs`, which
immediately frees the connection back to the pool before returning the
protocol version. That way we've already freed the connection by the
time we call `RemoteStore::queryPartialDerivationOutputMap`.

Allow substituting paths when building remotely using ssh-ng:// 
Until now, it was not possible to substitute missing paths from e.g.
`https://cache.nixos.org` on a remote server when building on it using
the new `ssh-ng` protocol.

This is because every store implementation except legacy `ssh://`
ignores the substitution flag passed to `Store::queryValidPaths` while
the `legacy-ssh-store` substitutes the remote store using
`cmdQueryValidPaths` when the remote store is opened with `nix-store
--serve`.

This patch slightly modifies the daemon protocol to allow passing an
integer value suggesting whether to substitute missing paths during
`wopQueryValidPaths`. To implement this on the daemon-side, the
substitution logic from `nix-store --serve` has been moved into a
protected method named `Store::substitutePaths` which gets currently
called from `LocalStore::queryValidPaths` and `Store::queryValidPaths`
if `maybeSubstitute` is `true`.

Fixes #2770

Update to use access-tokens configuration for github/gitlab access. 
This change provides support for using access tokens with other

gitlab.com (especially company-specific or foundation-specific
instances).

This change also provides the ability to specify the type of access
token being used, where different types may have different handling,
based on the forge type.

Fix max-jobs option 
After 0ed946aa61, max-jobs setting (-j/--max-jobs)
stopped working.

The reason was that nrLocalBuilds (which compared to maxBuildJobs to figure
out whether the limit is reached or not) is not incremented yet when tryBuild
is started; So, the solution is to move the check to tryLocalBuild.

Serialize SandboxMode enum to string for JSON 
Rather than showing an integer as the default, instead show the boolean
referenced in the description.

The nix.conf.5 manpage used to show "default: 0", which is unnecessarily
opaque and confusing (doesn't 0 mean false, even though the default is
true?); now it properly shows that the default is true.

Greg Hale a303c0b6dc Fetch commits from github/gitlab using Auth header 
`nix flake info` calls the github 'commits' API, which requires
authorization when the repository is private. Currently this request
fails with a 404.

This commit adds an authorization header when calling the 'commits' API.
It also changes the way that the 'tarball' API authenticates, moving the
user's token from a query parameter into the Authorization header.

The query parameter method is recently deprecated and will be disallowed
in November 2020. Using them today triggers a warning email.

regnat 5895184df4 Correctly call all the parent contructors of the stores 
Using virtual inheritance means that only the default constructors of
the parent classes will be called, which isn't what we want
 2020-09-16 13:53:09 +02:00
regnat 22afa8fb4d Separate store configs from the implems 
Rework the `Store` hierarchy so that there's now one hierarchy for the
store configs and one for the implementations (where each implementation
extends the corresponding config). So a class hierarchy like

```
StoreConfig-------->Store
    |                 |
    v                 v
SubStoreConfig----->SubStore
    |                 |
    v                 v
SubSubStoreConfig-->SubSubStore
```

(with virtual inheritance to prevent DDD).

The advantage of this architecture is that we can now introspect the configuration of a store without having to instantiate the store itself

regnat 3b57181f8e Separate the instantiation and initialisation of the stores 
Add a new `init()` method to the `Store` class that is supposed to
handle all the effectful initialisation needed to set-up the store.
The constructor should remain side-effect free and just initialize the
c++ data structure.

The goal behind that is that we can create “dummy” instances of each
store to query static properties about it (the parameters it accepts for
example)

is needed to handle the fallback path.

Fix unspecified behaviour in readStorePathCAMap 
When deploying a Hydra instance with current Nix master, most builds
would not run because of errors like this:

  queue monitor: error: --- Error --- hydra-queue-runner
  error: --- UsageError --- nix-daemon
  not a content address because it is not in the form '<prefix>:<rest>': /nix/store/...-somedrv

The last error message is from parseContentAddress, which expects a
colon-separated string, however what we got here is a store path.

Looking at the worker protocol, the following message sent to the Nix
daemon caused the error above:

  0x1E -> wopQuerySubstitutablePathInfos
  0x01 -> Number of paths
  0x16 -> Length of string
  "/nix/store/...-somedrv"
  0x00 -> Length of string
  ""

Looking at writeStorePathCAMap, the store path is indeed the first field
that's transmitted. However, readStorePathCAMap expects it to be the
*second* field *on my machine*, since expression evaluation order is a
classic form of unspecified behaviour[1] in C++.

This has been introduced in https://github.com/NixOS/nix/pull/3689,
specifically in commit 66a62b3189.

Include a long comment explaining the policy. Perhaps this can be moved

Also bump the daemon protocol minor version, so clients can tell whether
`wopBuildDerivation` supports trustless CA derivation building. I hope
to take advantage of this in a follow-up PR to support trustless remote
building with the minimal sending of derivation closures.

John Ericson 8d4162ff9e Separate auth and logic for the daemon 
Before, processConnection wanted to know a user name and user id, and
`nix-daemon --stdio`, when it isn't proxying to an underlying daemon,
would just assume "root" and 0. But `nix-daemon --stdio` (no proxying)
shouldn't make guesses about who holds the other end of its standard
streams.

Now processConnection takes an "auth hook", so `nix-daemon` can provide
the appropriate policy and daemon.cc doesn't need to know or care what
it is.

Matthew Bauer 641c950701 Add hashed-mirrors back 
Some users have their own hashed-mirrors setup, that is used to mirror
things in addition to what’s available on tarballs.nixos.org. Although
this should be feasable to do with a Binary Cache, it’s not always
easy, since you have to remember what "name" each of the tarballs has.
Continuing to support hashed-mirrors is cheap, so it’s best to leave
support in Nix. Note that NIX_HASHED_MIRRORS is also supported in
Nixpkgs through fetchurl.nix.

Note that this excludes tarballs.nixos.org from the default, as in
\#3689. All of these are available on cache.nixos.org.

example copying a 514 MiB closure over a virtual ethernet device with
a articial delay of just 1 ms took 343s. Now it takes 2.7s.

It's a tiny function which is:

 - doesn't work once we get CA drvs

I rewrote the one callsite to be forwards compatable with CA
derivations, and also potentially more performant: instead of reading in
the derivation it can ust consult the SQLite DB in the common case.

anymore. In fact, we can almost remove the method/hashAlgo arguments

We were calculating the nar hash wrong when the file ingestion method
was flat. I don't think there's anything we can do in that case but dump
the file again, so that's what I do.

As an optomization, we again could reuse the original dump for just the
recursive and non-sha256 case, but I rather do that after this fix, and
after my other PRs which deduplicate this code.

John Ericson fedfc913ad Use more std::visit to prepare for new variant 
N.B. not using `std::visit` for fetchurl because there is no attempt to
handle all the cases (e.g. no `else`) and lambda complicates early
return.

we don’t need a full storepath for a fixedoutput derivation. So just
putting the ingestion method + the hash is sufficient.

Eelco Dolstra 34f25124ba Make LocalStore::addToStore(srcPath) run in constant memory 
This reduces memory consumption of

  nix-instantiate \
    -E 'with import <nixpkgs> {}; runCommand "foo" { src = ./blender; } "echo foo"' \
    --option nar-buffer-size 10000

(where ./blender is a 1.1 GiB tree) from 1716 to 36 MiB, while still
ensuring that we don't do any write I/O for small source paths (up to
'nar-buffer-size' bytes). The downside is that large paths are now
always written to a temporary location in the store, even if they
produce an already valid store path. Thus, adding large paths might be
slower and run out of disk space. ¯\_(ツ)_/¯ Of course, you can always
restore the old behaviour by setting 'nar-buffer-size' to a very high
value.

regnat d38f860c3e Add a way to get all the outputs of a derivation with their label 
Generalize `queryDerivationOutputNames` and `queryDerivationOutputs` by
adding a `queryDerivationOutputMap` that returns the map
`outputName=>outputPath`

(not that this is not equivalent to merging the results of
`queryDerivationOutputs` and `queryDerivationOutputNames` as sets don't
preserve the order, so we would end up with an incorrect mapping).

squash! Add a way to get all the outputs of a derivation with their label
