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 (...) {}`.

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.

Allow missing flake.nix for --override-input target
|
|
nix-shell: set BASH variable to correct shell
|
|
fix nix repl not overriding existing bindings in :a
|
|
|
|
previously :a would override old bindings of a name with new values if the added
set contained names that were already bound. in nix 2.6 this doesn't happen any
more, which is potentially confusing.
fixes #6041
|
|
At this point, we don’t know if the input is a flake or not. So, we
should allow the user to override the input with a directory without a
flake.nix.
Ideally, we could figure whether the input was originally a flake or
not, but that would require instantiating the whole flake. So just
allow it to be missing here, and rely on checks later on to verify the
input for us.

Flake follows: resolve all follows to absolute
|
|
It's not possible in general to know in computeLocks, relative to
which path the follows was intended to be. So, we always resolve
follows to their absolute states when we encounter them (which can
either be in parseFlakeInput or computeLocks' fake input population).
