Merge pull request #7395 from obsidiansystems/evaluating-to-calling 
Change "while evaluating <fun>" to "while *calling*" in trace
 2022-12-02 15:53:57 +01:00
John Ericson 19c5394971 Change "while evaluating <fun>" to "while *calling*" in trace 
The old way was not correct.

Here is an example:
```
 $ nix-instantiate --eval --expr 'let x = a: throw "asdf"; in x 1' --show-trace
error: asdf

       … while evaluating 'x'

       at «string»:1:9:

            1| let x = a: throw "asdf"; in x 1
             |         ^

       … from call site

       at «string»:1:29:

            1| let x = a: throw "asdf"; in x 1
             |                             ^
```
and yet also:
```
 $ nix-instantiate --eval --expr 'let x = a: throw "asdf"; in x' --show-trace
<LAMBDA>
```

Here is the thing: in both cases we are evaluating `x`!

Nix is a higher-order languages, and functions are a sort of value. When
we write `x = a: ...`, `a: ...` is the expression that `x` is being
defined to be, and that is already a value. Therefore, we should *never*
get an trace that says "while evaluating `x`", because evaluating `a:
...` is *trival* and nothing happens during it!

What is actually happening here is we are applying `x` and evaluating
its *body* with arguments substituted for parameters. I think the
simplest way to say is just "while *calling* `x`", and so that is what I
changed it to.

Merge pull request #7353 from edolstra/gc-shutdown 
Fix random client failures during GC server shutdown
 2022-11-27 13:30:26 +01:00
Eelco Dolstra 5b798f6cae Fix random client failures during GC server shutdown 
We need to close the GC server socket before shutting down the active
GC client connections, otherwise a client may (re)connect and get
ECONNRESET. But also handle ECONNRESET for resilience.

Fixes random failures like

  GC socket disconnected
  connecting to '/tmp/nix-shell.y07M0H/nix-test/default/var/nix/gc-socket/socket'
  sending GC root '/tmp/nix-shell.y07M0H/nix-test/default/store/kb5yzija0f1x5xkqkgclrdzldxj6nnc6-non-blocking'
  reading GC root from client: error: unexpected EOF reading a line
  1 store paths deleted, 0.00 MiB freed
  error: reading from file: Connection reset by peer

in gc-non-blocking.sh.

Don't use GC_STRNDUP
 2022-11-26 08:50:54 +01:00
Eelco Dolstra 0b4c4d7434 Don't use GC_STRNDUP 
It calls strlen() on the input (rather than simply copying at most
`size` bytes), which can fail if the input is not zero-terminated and
is inefficient in any case.

Fixes #7347.

Taeer Bar-Yam b13fd4c58e Fix why-depends for CA derivations 
why-depends assumed that we knew the output path of the second argument.
For CA derivations, we might not know until it's built. One way to solve
this would be to build the second installable to get the output path.

In this case we don't need to, though. If the first installable (A)
depends on the second (B), then getting the store path of A will
necessitate having the store path B. The contrapositive is, if the store
path of B is not known (i.e. it's a CA derivation which hasn't been
built), then A does not depend on B.
