Display progress when running copyPaths (nix copy)
|
|
`nix copy` operations did not show progress. This is quite confusing.
Add a `progressSink` which displays the progress during `copyPaths`,
pretty much copied from `copyStorePath`.
Fixes https://github.com/NixOS/nix/issues/8000

Currently the valid key is only present when the path is invalid, which
makes checking path validity more complex than it should be. With this
change, the valid key can always be used to check if a path is valid
|
|
|
|
Avoid needless work and throwing away invariants.
These conversions date back to when `StorePath` was in Rust and there
were issues with it missing utility methods.
|
|
Originally there was no `path-info.*`, then there was `path-info.hh`,
then there was `path-info.cc`, but only for new things. Moving this
stuff over makes everything consistent.

Fix #6209
When trying to run `nix log <installable>`, try first to resolve the derivation pointed to
by `<installable>` as it is the resolved one that holds the build log.
This has a couple of shortcomings:
1. It’s expensive as it requires re-reading the derivation
2. It’s brittle because if the derivation doesn’t exist anymore or can’t
be resolved (which is the case if any one of its build inputs is missing),
then we can’t access the log anymore
However, I don’t think we can do better (at least not right now).
The alternatives I see are:
1. Copy the build log for the un-resolved derivation. But that means a
lot of duplication
2. Store the results of the resolving in the db. Which might be the best
long-term solution, but leads to a whole new class of potential
issues.

While trying to use an alternate directory for my Nix installation, I
noticed that nix's output didn't reflect the updated state
directory. This patch corrects that and now prints the warning before
attempting to create the directory (if the directory creation fails,
it wouldn't have been obvious why nix was attempting to create the
directory in the first place).
With this patch, I now get the following warning:
warning: '/home/deck/.var/app/org.nixos.nix/var/nix' does not
exist, so Nix will use '/home/deck/.local/share/nix/root' as a
chroot store

This hang for some reason didn't trigger in the Nix build, but did
running 'make installcheck' interactively. What happened:
* Store::addMultipleToStore() calls a SinkToSource object to copy a
path, which in turn calls LegacySSHStore::narFromPath(), which
acquires a connection.
* The SinkToSource object is not destroyed after the last bytes has
been read, so the coroutine's stack is still alive and its
destructors are not run. So the connection is not released.
* Then when the next path is copied, because max-connections = 1,
LegacySSHStore::narFromPath() hangs forever waiting for a connection
to be released.
The fix is to make sure that the source object is destroyed when we're
done with it.

Specifically, if we're not root and the daemon socket does not exist,
then we use ~/.local/share/nix/root as a chroot store. This enables
non-root users to download nix-static and have it work out of the box,
e.g.
ubuntu@ip-10-13-1-146:~$ ~/nix run nixpkgs#hello
warning: '/nix' does not exists, so Nix will use '/home/ubuntu/.local/share/nix/root' as a chroot store
Hello, world!

Bring back the possibility to copy CA paths with no reference (like the
outputs of FO derivations or stuff imported at eval time) between stores
that have a different prefix.

Use one of `get` or `getOr` instead which will either return a null-pointer (with a nicer error message) or a default value when the key is missing.

1. `DerivationOutput` now as the `std::variant` as a base class. And the
variants are given hierarchical names under `DerivationOutput`.
In 8e0d0689be797f9e42f9b43b06f50c1af7f20b4a @matthewbauer and I
didn't know a better idiom, and so we made it a field. But this sort
of "newtype" is anoying for literals downstream.
Since then we leaned the base class, inherit the constructors trick,
e.g. used in `DerivedPath`. Switching to use that makes this more
ergonomic, and consistent.
2. `store-api.hh` and `derivations.hh` are now independent.
In bcde5456cc3295061a0726881c3e441444dd6680 I swapped the dependency,
but I now know it is better to just keep on using incomplete types as
much as possible for faster compilation and good separation of
concerns.

Also use std::string_view in a few more places.

Add back `copyClosure` for plain `StorePath`s
|
|
This was removed in 2e199673a523fa81de31ffdd2a25976ce0814631 when
`copyPath` transitioned to use `RealisedPath`. But then in
e9848beca704d27a13e28b4403251725bd485bb2 we added it back just for
`realisedPath`.
I think it is a good utility function --- one can easily imagine it
becoming optimized in the future, and copying paths *violating* the
closure is a very niche feature.
So if we have `copyPaths` for both sorts of paths, I think we should
have `copyClosure` for both sorts too.

Use the macros more, so we properly skip work when the log level
excludes. Also log the daemon operation number on the daemon side.

Allow references in addPath

Doesn’t change much so far because everything is still using it
synchronously, but should allow the binary cache to fetch stuff in
parallel

Rather than having them plain strings scattered through the whole
codebase, create an enum containing all the known experimental features.
This means that
- Nix can now `warn` when an unkwown experimental feature is passed
(making it much nicer to spot typos and spot deprecated features)
- It’s now easy to remove a feature altogether (once the feature isn’t
experimental anymore or is dropped) by just removing the field for the
enum and letting the compiler point us to all the now invalid usages
of it.

Allow to pass a set of references to be added as info to the added paths.
|
|
This fixes a bug in the garbage collector where if a path
/nix/store/abcd-foo is valid, but we do a
isValidPath("/nix/store/abcd-foo.lock") first, then a negative entry
for /nix/store/abcd is added to pathInfoCache, so /nix/store/abcd-foo
is subsequently considered invalid and deleted.
|
|
I had started the trend of doing `std::visit` by value (because a type
error once mislead me into thinking that was the only form that
existed). While the optomizer in principle should be able to deal with
extra coppying or extra indirection once the lambdas inlined, sticking
with by reference is the conventional default. I hope this might even
improve performance.

This adds a new store operation 'addMultipleToStore' that reads a
number of NARs and ValidPathInfos from a Source, allowing any number
of store paths to be copied in a single call. This is much faster on
high-latency links when copying a lot of small files, like .drv
closures.
For example, on a connection with an 50 ms delay:
Before:
$ nix copy --to 'unix:///tmp/proxy-socket?root=/tmp/dest-chroot' \
/nix/store/90jjw94xiyg5drj70whm9yll6xjj0ca9-hello-2.10.drv \
--derivation --no-check-sigs
real 0m57.868s
user 0m0.103s
sys 0m0.056s
After:
real 0m0.690s
user 0m0.017s
sys 0m0.011s
