Eelco Dolstra 0356f14459 Add 'nix diff-closures' command 
This command makes it easier to see what changed between two closures,
i.e. what packages/versions got added or removed, and whether there
were any notable changes in path size.

For example:

  $ nix diff-closures /nix/var/nix/profiles/system-655-link /nix/var/nix/profiles/system-658-link
  blender-bin: 2.83.0 → 2.83.2, -294.2 KiB

  firmware-linux-nonfree: 2020-01-22 → 2020-05-19, +30827.7 KiB
  ibus: -21.8 KiB
  initrd-linux: 5.4.46 → 5.4.51, +16.9 KiB
  libexif: 0.6.21 → 0.6.22, +497.6 KiB

Eelco Dolstra cff2157185 Revert "LocalStore::addToStore(srcPath): Handle the flat case" 
This reverts commit a2c27022e9. See
addToStoreSlow(), we don't need to handle this case efficiently
anymore. In fact, we can almost remove the method/hashAlgo arguments
since the non-recursive and/or non-SHA256 are almost not used anymore.

John Ericson 650c2c6558 Rename variable nar -> dump according to TODO 2020-07-14 21:28:50 +00:00
John Ericson 8173e7bfef Fix localhost::addToStore(...Path...) 
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 592851fb67 LocalStore::addToStoreFromDump copy in chunks 
Rather than copying byte-by-byte, we let the coroutine know how much
data we would like it to send back to us.
 2020-07-14 13:56:36 +00:00
John Ericson 9de96ef7d4 Dedup LocalStore::addToStore* 
The downsides is that the coroutine has byte-by-byte loop transfer. Will
fix that next.
 2020-07-14 13:56:36 +00:00
John Ericson c86fc3a965 Crudely make addToStoreFromDump take Source not string 
I just as little beyond the type as possible, so the implementation
changes this enables can be reviewed separately.

Fix gitlab-fetcher to obtain tags and branches 
Until now, the `gitlab`-fetcher determined the source's rev by checking
the latest commit of the given `ref` using the
`/repository/branches`-API.

This breaks however when trying to fetch a gitlab-repo by its tag:

```
$ nix repl
nix-repl> builtins.fetchTree gitlab:Ma27/nvim.nix/0.2.0
error: --- Error ------------------------------------------------------------------------------------- nix
unable to download 'https://gitlab.com/api/v4/projects/Ma27%2Fnvim.nix/repository/branches/0.2.0': HTTP error 404 ('')
```

When using the `/commits?ref_name`-endpoint[1] you can pass any kind of
valid ref to the `gitlab`-fetcher.

Please note that this fetches the only first 20 commits on a ref,
unfortunately there's currently no endpoint which only retrieves the
latest commit of any kind of `ref`.

John Ericson 230c9b4329 Change types to prepare the way for CA derivations 
We've added the variant to `DerivationOutput` to support them, but made
`DerivationOutput::path` partial to avoid actually implementing them.

With this chage, we can all collaborate on "just" removing
`DerivationOutput::path` calls to implement CA derivations.
 2020-07-12 23:53:33 +00:00
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.

Fix ANSI color constants 
The `m` acts as termination-symbol when declaring graphics. Because
of this, the `;1m` doesn't have any effect and is directly printed to

{ outPath = "/nix/store/s0f0iz4a41cxx2h055lmh6p2d5k5bc6r-source"; rev = "e73e45b723a9a6eecb98bd5f3df395d9ab3633b6"; revCount = ;1m428; shortRev = "e73e45b"; submodules = ;1mfalse; }

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.

runs 'hello' from the 'nixpkgs' inputs of the 'hydra' flake.
