Move some stuff from `Settings` to a new `FetchSettings`.
|
|
Starting work on #5638
The exact boundary between `FetchSettings` and `EvalSettings` is not
clear to me, but that's fine. First lets clean out `libstore`, and then
worry about what, if anything, should be the separation between those
two.
|
|
This switches addPath from `printStorePath` to `toRealPath`.

nix/why-depends: fix output when not using `--precise`
|
|
Also use std::string_view in a few more places.
|
|
|
|
- From what I see it is an implementation detail
but is no longer configurable from the settings
|
|
Issue #6160.
|
|
Replace defaultBla.$system with bla.$system.default
|
|
This is more consistent with flake terminology.
|
|
Add support for sourcehut input scheme
|
|
|
|
|
|
This also simplifies some InstallableFlake logic and fixes 'nix
bundle' parsing its installable twice.
Fixes #5532.
|
|
Add verbosity to nix profile upgrade

Fix deadlocked nix-daemon zombies on darwin #3294
|
|
|
|
Followup of https://github.com/NixOS/nix/pull/6086. This time adding a
warning if no packages are upgraded.
|
|
Fixes #5645
|
|
add descriptive output when creating templates
|
|
|
|
|
|
|
|
this includes a `welcomeText` attribute which can be set in the
template, as well as outputing which files were created.
|
|
|
|
This removes some duplicated logic, and fixes "nix bundle" parsing its
installable twice.
|
|
|
|
parseInstallables(): Don't try the flake attr path prefixes when no fragment is specified
|
|
warn if there are no matches and give notice of removing packages as
they are found
|
|
is specified
Fixes #5880.

On Nix 2.6 the output of `nix why-depends --all` seems to be somewhat
off:
$ nix why-depends /nix/store/kn47hayxab8gc01jhr98dwyywbx561aq-nixos-system-roflmayr-21.11.20220207.6c202a9.drv /nix/store/srn5jbs1q30jpybdmxqrwskyny659qgc-nix-2.6.drv --derivation --extra-experimental-features nix-command --all

└───/nix/store/99hlc7i4gl77wq087lbhag4hkf3kvssj-nixos-system-hydra-21.11pre-git.drv
Please note that `[...]-system-units.drv` is supposed to be a direct
child of `[...]-etc.drv`.
The reason for that is that each new level printed by `printNode` is
four spaces off in comparison to `nix why-depends --precise` because the
recursive `printNode()` only prints the path and not the `tree*`-chars in
the case of `--precise` and in this format the path is four spaces further
indented, i.e. on a newline, but on the same level as the path's children, i.e.
/nix/store/kn47hayxab8gc01jhr98dwyywbx561aq-nixos-system-roflmayr-21.11.20220207.6c202a9.drv
└───/: …1-p8.drv",["out"]),("/nix/store/g8bpgfjhh5vxrdq0w6r6s64f9kkm9z6c-etc.drv",["out"]),("/nix/store/…
→ /nix/store/g8bpgfjhh5vxrdq0w6r6s64f9kkm9z6c-etc.drv
As you can see `[...]-etc.drv` is a direct child of the root, but four
spaces indented. This logic was directly applied to the code-path with
`precise=false` which resulted in `tree*` being printed four spaces too
deep.
In case of no `--precise`, `hits[hash]` is empty and the path itself
should be printed rather than hits using the same logic as for `hits[hash]`.
With this fix, the output looks correct now:
/nix/store/kn47hayxab8gc01jhr98dwyywbx561aq-nixos-system-roflmayr-21.11.20220207.6c202a9.drv

repl/load-flake: throw error if path isn't specified
|
|
I noticed that occasional Ctrl-C leaves *.lock files around.
`nix-daemon`'s journal logs contained crashes like:
nix-daemon[30416]: terminate called after throwing an instance of 'nix::SysError'
nix-daemon[30416]: what(): error: writing to file: Broken pipe
And core dump backtraces pointed at `teriminate()` call from
destructors:
...
_Unwind_Resume ()
nix::ignoreException() ()
nix::LocalDerivationGoal::~LocalDerivationGoal()
...
void ignoreException()
{
try {
throw;
} catch (std::exception & e) {
printError("error (ignored): %1%", e.what());
}
}
The crashes happen when client side closes early and printError() throws
an IO error.
The change wraps `ignoreException()` into blanket `try { ... } catch (...) {}`.
Closes: https://github.com/NixOS/nix/issues/6046

Fixes #5985.

This changes the representation of the interrupt callback list to
be safe to use during interrupt handling.
Holding a lock while executing arbitrary functions is something to
avoid in general, because of the risk of deadlock.
Such a deadlock occurs in https://github.com/NixOS/nix/issues/3294
where ~CurlDownloader tries to deregister its interrupt callback.
This happens during what seems to be a triggerInterrupt() by the
daemon connection's MonitorFdHup thread. This bit I can not confirm
based on the stack trace though; it's based on reading the code,
so no absolute certainty, but a smoking gun nonetheless.
