This commit partially reverts 48662d151bdf4a38670897beacea9d1bd750376a. When
copying from an older store (in my case a store running Nix 1.11.7), nix would
throw errors about there being no hash. This is fixed by recalculating the hash.

Allow global config settings to be defined in multiple Config
classes. For example, this means that libutil can have settings and
evaluator settings can be moved out of libstore. The Config classes
are registered in a new GlobalConfig class to which config files
etc. are applied.
Relevant to https://github.com/NixOS/nix/issues/2009 in that it
removes the need for ad hoc handling of useCaseHack, which was the
underlying cause of that issue.

copyStorePath() now pipes the output of srcStore->narFromPath()
directly into dstStore->addToStore(). The sink used by the former is
converted into a source usable by the latter using
boost::coroutine2. This is based on [1].
This reduces the maximum resident size of
$ nix build --store ~/my-nix/ /nix/store/b0zlxla7dmy1iwc3g459rjznx59797xy-binutils-2.28.1 --substituters file:///tmp/binary-cache-xz/ --no-require-sigs
from 418592 KiB to 53416 KiB. (The previous commit also reduced the
runtime from ~4.2s to ~3.4s, not sure why.) A further improvement will
be to download files into a Sink.

Issue #1969.

Fixes #1340.

builtins.path allows specifying the name of a path (which makes paths
with store-illegal names now addable), allows adding paths with flat
instead of recursive hashes, allows specifying a filter (so is a
generalization of filterSource), and allows specifying an expected
hash (enabling safe path adding in pure mode).

a thread pool
|
|
You can now say '--store /tmp/nix' instead of '--store local?root=/tmp/nix'.
|
|
Fixes #1599.

I don't remember what the reasoning was here, but security is provided
by the signatures, not by whether the hash is provided by the other
store.
|
|
And print them (separately from the progress bar) given sufficient -v
flags.
|
|
In particular, this allows more relevant activities ("substituting X")
to supersede inferior ones ("downloading X").

They're the same thing after all.
Example:
$ nix build --store local?root=/tmp/nix nixpkgs.firefox-unwrapped
[0/1 built, 49/98 copied, 16.3/92.8 MiB DL, 55.8/309.2 MiB copied] downloading 'https://cache.nixos.org/nar/0pl9li1jigcj2dany47hpmn0r3r48wc4nz48v5mqhh426lgz3bz6.nar.xz'
|
|
It now shows the amount of data copied:
[8/1038 copied, 160.4/1590.9 MiB copied] copying path '...'

E.g.
$ nix path-info --json --store https://cache.nixos.org nixpkgs.thunderbird -S

"closureDownloadSize": 84745960

Now you get
[

"valid": false
}
]

Fixes #1438.

As shlevy pointed out, static variables in C++11 have thread-safe
initialisation.
|
|
Also simplify the Hash API.
Fixes #1437.
|
|
Functions like copyClosure() had 3 bool arguments, which creates a
severe risk of mixing up arguments.
Also, implement copyClosure() using copyPaths().

client# error: size mismatch importing path ‘/nix/store/ywf5fihjlxwijm6ygh6s0a353b5yvq4d-libidn2-0.16’; expected 0, got 120264
This is mostly an artifact of the NixOS VM test environment, where the
Nix database doesn't contain hashes/sizes.

This restores the old behaviour.
|
|
For backwards compatibility, if the URI is just a hostname, ssh://
(i.e. LegacySSHStore) is prepended automatically.
Also, all fields except the URI are now optional. For example, this is
a valid nix.machines file:
local?root=/tmp/nix
This is useful for testing the remote build machinery since you don't
have to mess around with ssh.
|
|
This default implementation of buildPaths() does nothing if all
requested paths are already valid, and throws an "unsupported
operation" error otherwise. This fixes a regression introduced by
c30330df6f67c81986dfb124631bc756c8e58c0d in binary cache and legacy
SSH stores.
|
|
This makes all config options self-documenting.
Unknown or unparseable config settings and --option flags now cause a
warning.
|
|
|
|
The typical use is to inherit Config and add Setting<T> members:
class MyClass : private Config
{
Setting<int> foo{this, 123, "foo", "the number of foos to use"};
Setting<std::string> bar{this, "blabla", "bar", "the name of the bar"};
MyClass() : Config(readConfigFile("/etc/my-app.conf"))
{
std::cout << foo << "\n"; // will print 123 unless overriden
}
};
Currently, this is used by Store and its subclasses for store
parameters. You now get a warning if you specify a non-existant store
parameter in a store URI.

Using the empty string is likely to be ambiguous in some contexts.
