pkgs.fetchurl supports an executable argument, which is especially nice
when downloading a large executable. This patch adds the same option to
nix-prefetch-url.
I have tested this to work on the simple case of prefetching a little
executable:
1. nix-prefetch-url --executable https://my/little/script
2. Paste the hash into a pkgs.fetchurl-based package, script-pkg.nix
3. Delete the output from the store to avoid any misidentified artifacts
4. Realise the package script-pkg.nix
5. Run the executable
I repeated the above while using --name, as well.
I suspect --executable would have no meaningful effect if combined with
--unpack, but I have not tried it.
Since 108debef6f we allow a
`url`-attribute for the `github`-fetcher to fetch tarballs from
self-hosted `gitlab`/`github` instances.
However it's not used when defining e.g. a flake-input
foobar = {
type = "github";
url = "gitlab.myserver";
/* ... */
}
and breaks with an evaluation-error:
error: --- Error --------------------------------------nix
unsupported input attribute 'url'
(use '--show-trace' to show detailed location information)
This patch allows flake-inputs to be fetched from self-hosted instances
as well.
`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.
Mac OS multi-user installations are currently broken because all requests
made by nix-daemon to the binary cache fail with:
```
unable to download ... Problem with the SSL CA cert (path? access rights?) (77).
```
This change ensures that the nix-daemon knows where to find the SSL CA cert file.
Fixes#2899 and #3261.
It is apparently required for using `toJSONObject()`, which we do inside
the header file (because it's in a template).
This was accidentally working when building Nix itself (presumably because
`config.hh` was always included after `nlohman/json.hpp`) but caused a
(pretty dirty) build failure in the perl bindings package.
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
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)
