Change ErrorHint so that, internally, it just holds an enum with a
lightweight reference to whatever parts of the error it needs to
generate a hint. Then we can move the formatting logic into a
Display function for ErrorHint, and do away with ErrorDetail entirely.
Move the "hint" function into Error, and use Option rather than Result.
(I'm using Option here because it's not really an error case not to have
a hint; we just either have a hint, or we don't.)
This commit replaces all occurrences of `llvm-tools-preview` with
`llvm-tools`, because it became a stable feature with Rust 1.60, thereby
making the `-preview` prefix obsolete. Beside this, `llvm-tools-preview`
is a redirection to the latter one anyway.
However, it does not work the other way around. At the moment, it is not
possible to execute the `maint/coverage` script on a NixOS system,
because the rustup component list only includes `llvm-tools`, but not
`llvm-tools-preview`, thereby making this change necessary.
Clippy now complains about `let _ = (expr_producing_a_future);`,
which is probably smart, since maybe you wanted to await that future
and ignore the result. So it seems that the right way to get rid of
an unwanted Receiver is now to drop it explicitly.
Closes#749
This warning kind of snuck up on us! (See #748) For now, let's
disable it. (I've cleaned it up in a couple of examples, since
those are meant to be more idiomatic and user-facing.)
Closes#748.
This commit adds a test called `shebang`, which checks if all shebangs
in scripts use relative paths through `#/usr/bin/env`, rather than
absolute paths, such as `#/bin/bash`.
See 833b10575b.
This required rewriting some of our error handling code in
command-line processing, since the toml crate now displays and
reports errors differently. (Admittedly, this code still is kind of
ugly, but at least it is nicely hidden.)
It turns out that the credential is only calculated as an
intermediate result in order to blind keys and produce the
subcredential. As such, it has no need to leave the hscrypto module.
This commit changes the shebang in all shell scripts from absolute
paths (such as `/bin/bash` or `/usr/bin/python3`) to the `/usr/bin/env`
binary with the accompanying interpreter as it's argument.
The reason for this are as follows:
- NixOS cannot work with absolute paths
- BSD systems install their packages in /usr/local/bin
Previously, the offset was set to 12 hours unconditionally (like the
spec says). But based on a conversation on tor-dev, it seems that
the offset should actually be 12 times the voting interval.
I'm also opening an MR to change the spec.
