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.

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.

The `m` acts as termination-symbol when declaring graphics. Because

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.

Matthew Bauer af95a7c16b Add name to BasicDerivation
We always have a name for BasicDerivation, since we have a derivation

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

John Ericson f4a5913125 hashed-mirrors: Use parsed derivation output rather than reconstructing it
Now the derivation outputs are parsed up front, we can avoid a reparse
by doing it. Also, this just feels a bit better as the `output*` env
vars are more of a `libnixexpr` interface than `libnixstore` interface:
ultimately, it's the derivation outputs that decide whether the
derivation is fixed-output.

Yes, hashed mirrors might go away with #3689, but this bit of code would
be moved rather than deleted, so it's worth doing a cleanup anyways I
think.

John Ericson 639e20dc3e Prevent '%' in URL from causing crashes
We have a larger problem that passsing computed strings to the first
variable argument of many exception constructors is unsafe because that
first variable argument is interpreted not as a plain string, but format
string, and if it contains '%' boost::format will abort, since there are
no arguments to the format string.

In this particular instance '%' was used as part of an escape code in a
URL, which, when the download failed, caused Nix to abort displaying the
`FileTransferError`.

Carlo Nucera 289b9b8dcf Create a new TeeSink abstraction
This is a bit complex because we want to expose extra functionality the
wrapped class has. Perhaps there is some inheritancy trickery to do this
nicer, but I don't know it, and this is the first thing we tried after a
series of attempts that did build.

This design is kind of like that of Rust's Writer, Reader, or Iter
adapters, which impliment more traits based on what the inner type
implements.

This was introduced in fa125b9b28, and
then "reverted" in 1cf4801108, except that
revert left the struct around doing nothing useful.

We're removing it all the way now because we want to make a new
`TeeSink` complementing the already-exiting `TeeSource`, that is
actually a completely different concept as far as the class hierarchy is
concerned.

Matthew Bauer c214cda940 Correctly substitute from different storeDir
Originally, the test was only checking for different “real” storeDir.
That’s an easy case to handle, but the much harder one is if different
virtual store dirs are used. To do this, we need the SubstitutionGoal
to know about the ca, so it can recalculate the path to copy it over.
An important note here is that the store path passed to copyStorePath
needs to be one for srcStore - so that queryPathInfo works properly.

This also adds an error message when the store path from queryPathInfo
is different from the one we requested.

Matthew Bauer b2cb288cdd Add makeFixedOutputPathFromCA function
This puts what we are already doing into a shared method. It just
needs a path name and a ca and produces a store path.

Matthew Bauer 79c169d1c6 Allow substituting from different storeDir
Substituters can substitute from one store dir to another with a
little bit of help. The store api just needs to have a CA so it can
recompute the store path based on the new store dir. We can only do
this for fixed output derivations with no references, though.

This function was used in only one place, where it could easily be
replaced by readDerivation() since it's not
performance-critical. (This function appears to have been modelled
after queryDerivationOutputs(), which exists only to make the garbage
collector faster.)

This fixes an issue where lockfile generation was not idempotent:
after updating a lockfile, a "follows" node would end up pointing to a
new copy of the node, rather than to the original node.

empty hash is wanted.
