Starts progress on #5729.
The idea is that we should not have these default methods throwing
"unimplemented". This is a small step in that direction.
I kept `addTempRoot` because it is a no-op, rather than failure. Also,
as a practical matter, it is called all over the place, while doing
other tasks, so the downcasting would be annoying.
Maybe in the future I could move the "real" `addTempRoot` to `GcStore`,
and the existing usecases use a `tryAddTempRoot` wrapper to downcast or
do nothing, but I wasn't sure whether that was a good idea so with a
bias to less churn I didn't do it yet.
We now memoize on Bindings / list element vectors rather than Values,
so that e.g. two Values that point to the same Bindings will be
printed only once.
This is useful whenever we want to evaluate something to a store path
(e.g. in get-drvs.cc).
Extracted from the lazy-trees branch (where we can require that a
store path must come from a store source tree accessor).
Fixes
nix-daemon: src/libstore/sqlite.cc:97: nix::SQLiteStmt::Use::Use(nix::SQLiteStmt&): Assertion `stmt.stmt' failed.
which happens because the daemon doesn't properly handle the case
where ca-derivations isn't enabled at daemon startup.
Restart the tests (at most once) on `unexpected EOF` errors.
This is truly ugly, but might prevent half of the CI runs to fail
because of https://github.com/NixOS/nix/issues/3605
This was introduced in #6174. However fetch{url,Tarball} are legacy
and we shouldn't have an undocumented attribute that does the same
thing as one that already exists ('sha256').
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.
- Make sure that it starts even without the `nix-command` xp feature
- Fail if it doesn’t manage to start
This fixes a 30s wait for every test in `init.sh` as the daemon couldn’t
start, but the code was just waiting 30s and continuing as if everything
was all right.
