Fixes an instance of
nix: src/libutil/util.cc:139: nix::Path nix::canonPath(PathView, bool): Assertion `path != ""' failed.
... which I've been getting in one of my shells for some reason.
I have yet to find out why TMPDIR was empty, but it's no reason for
Nix to break.
I was using by mistake the .#nix-clangStdenv shell to retrieve clangd.
This clangd is unusable with the project and constantly segfaults.
Let's explicitly state which shell the user should use in the docs.
I don't really understand the source of this segfault. I assume it's
related to a clang version incompatibility. (16.0.6 for
.#nix-clangStdenv 14.0.6 for .#native-clangStdenvPackages)

- Align the “frequent” release cycle with the calendar
- The 6-month release cycle is hard to keep track of. A monthly
release will make it much easier to remember the release date.
- Officialise the support for a stable version maintained for as long as NixOS stable
- This is already the case in practice, it just happens that the
“stable” Nixpkgs version is whichever version was deemed
stable-enough at the time of the NixOS release.
Officialise that by cutting a new major release alongside each NixOS one.
Note that this breaks whatever semver compatibility Nix might pretend to
have, but I don't think it makes sense any way.
In a daemon-based Nix setup, some options cannot be overridden by a
client unless the client's user is considered trusted.
Currently, if an untrusted user tries to override one of those
options, we are silently ignoring it.
This can be pretty confusing in certain situations.
e.g. a user thinks he disabled the sandbox when in reality he did not.
We are now sending a warning message letting know the user some options
have been ignored.
Related to #1761.
This is a cherry-pick of 9e0f5f803f.
The above commit has been reverted by
a59e77d9e5 to prevent spamming warnings
with experimental features, but these are now totally ignored on the
daemon side, so there's no reason for the revert any more.
Previously, `state.mkList()` would set the type of the value to tList
and allocate the list vector, but it would not initialize the values
in the list. This has two problems:
* If an exception occurs, the list is left in an undefined state.
* More importantly, for multithreaded evaluation, if a value
transitions from thunk to non-thunk, it should be final (i.e. other
threads should be able to access the value safely).
To address this, there now is a `ListBuilder` class (analogous to
`BindingsBuilder`) to build the list vector prior to the call to
`Value::mkList()`. Typical usage:
auto list = state.buildList(size);
for (auto & v : list)
v = ... set value ...;
vRes.mkList(list);
* Add regression test
* Fix 'no repo' test so it doesn't succeed if the data is still in cache
* Use git_revparse_single inside git-utils instead of reimplementing the same logic.
