Qyriad 677cf75473 repl: log errors writing to history file
These errors are now logged and explicitly ignored, rather than
implicitly ignored.

repl: do not crash when tab-completing import errors
File not found while importing causes a SysError, not an EvalError,
which is not currently caught by the tab-completion handler. Ignoring
all SysErrors might seem "dangerous" but this is the tab-completion
handler, any exception being bubbled up from there causes unexpected
behavior (causes the whole repl to exit).

Fixes #340.

jade d05e0b9f1f fix: enlarge envSize by several times to not be close to nixpkgs size
nixpkgs has 23000 attributes, and our previous limit would be hit if you
have more than one nixpkgs in the environment, for example, because
`repl-overlays` will load the new stuff from the environment on top of
the existing environment.

This is not really testable since if we did write such a test, it would
just be testing this constant tbh...

Qyriad 6881476232 libfetchers: fallback to memory SQLite if fs IO fails
nix::fetchers::CacheImpl uses $XDG_CACHE_HOME, or its default based on
$HOME, to store its SQLite database. If the current process can't write
to that directory for whatever reason, though, any eval-time fetching
would fail just initializing the cache.

With this change, IO errors initializing the fetcher cache are logged
but ignored, and nix::fetchers::CacheImpl falls back to an in-memory¹
database instead.

Notably, this will fix any uses eval fetching while Lix itself is being
run in a derivation builder (such as during tests), as the derivation
builder does not set $XDG_CACHE_HOME, and sets $HOME to the non-existent
directory /homeless-shelter.

Before:

$ env -u XDG_CACHE_HOME HOME=/homeless-shelter nix -Lv eval --impure -E 'fetchTarball "https://git.lix.systems/lix-project/lix/archive/main.tar.gz"'
error:
       … while calling the 'fetchTarball' builtin

After:

Qyriad 20981461d4 print type and value in "flake attr is not a derivation" errors
This turns errors like:

error: flake output attribute 'hydraJobs' is not a derivation or path

into errors like:

This change affects all InstallableFlake commands.

libutil: Create chmodPath function
Move the identical static `chmod_` functions in libstore to
libutil. the function is called `chmodPath` instead of `chmod`
as otherwise it will shadow the standard library chmod in the nix
namespace, which is somewhat confusing.

Qyriad 4eb6779ea8 fix -Wdeprecated-copy on clang (BaseError copy assignment)
2bbe3efd1¹ added the -Wdeprecated-copy warning, and fixed the instances
of it which GCC warned about, in HintFmt and ref<T>. However, when
building with Clang, there is an additional deprecated-copy warning in
BaseError. This commit explicitly defaults the copy assignment operator
for BaseError and silences this warning.

eldritch horrors 774c56094f libstore: fix old RemoteStore::addToStore serializer
having the serializer write into `*conn` is not legal because we are
in a sinkToSource that will be drained by the remote we're connected
to. writing into `*conn` directly can break the framing protocol. it
is unlikely this code was ever run: to protocol it caters to is from
2016(!) and thoroughly untested in-tree, and since it's been present
since nix 2.17 and the 1.18 protocol broken here is nix 2.0 we might
safely assume that daemons older than nix 2.1 are no longer used now

see also #325 (though that wants <2.3 gone, this is sadly only <2.1)

Alyssa Ross 139d31f876 Improve nix-store --delete failure message
On several occasions I've found myself confused when trying to delete
a store path, because I am told it's still alive, but
nix-store --query --roots doesn't show anything.  Let's save future
users this confusion by mentioning that a path might be alive due to
having referrers, not just roots.

These commands outputs data that may not end with a newline. This
causes problems when the progress bar redraws, as that completely
wipes the last line of output. As nix key generate-secret outputs
a single line of text with no output, it shows up entirely blank,
making it look like nothing happened.

derived-path: refuse built derived path with a non-derivation base
Example: /nix/store/dr53sp25hyfsnzjpm8mh3r3y36vrw3ng-neovim-0.9.5^out

This is nonsensical since selecting outputs can only be done for a
buildable derivation, not for a realised store path. The build worker
side of things ends up crashing with an assertion when trying to handle
such malformed paths.

nix3-build: show all FOD errors with --keep-going
Basically I'd expect the same behavior as with `nix-build`, i.e.
with `--keep-going` the hash-mismatch error of each failing
fixed-output derivation is shown.

The approach is derived from `Store::buildPaths` (`entry-point.cc`):
instead of throwing the first build-result, check if there are any build
errors and if so, display all of them and throw after that.

Unfortunately, the BuildResult struct doesn't have an `ErrorInfo`
(there's a FIXME for that at least), so I have to construct my own here.
This is a rather cheap bugfix and I decided against touching too many
parts of libstore for that (also I don't know if that's in line with the
ongoing refactoring work).

Closes lix-project/lix#302

libutil: remove the interrupt-blocking code
The interrupt-blocking code was originally introduced 20 years ago so that
trying to log an error message does not result in an interrupt exception being
thrown and then going unhandled (c8d3882cdc).
However, the logging code does not check for interrupts any more
(054be50257), so this reasoning is no longer
applicable. Delete this code so that later interrupts are unblocked again, for
example in the next line entered into the repl.
