We want to only use TODO in the codebase for non-blockers, and open
tickets for anything that is a bigger blocker than a TODO. These
XXXXs seem like definite non-blockers to me.
Part of arti#231.
The redundant method was a `to_owned` that probably shouldn't have
been called that. It was only used in one place.
The tests should get tor-linkspec's line coverage up above 90%.
This was a relic of the old, now-unused "caret_enum!" macro.
Removing it gets caret's coverage to 100%.
Yes, technically this is a semver breaker on caret.
For this one I just wrote some "are things completely broken" tests
for the rand_compat wrappers. These won't detect subtle biases in
the RNGs! They'll only let you know if the wrappers have screwed up
in some way that always sets a given bit to 1 or 0.
This is mostly a finger exercise, and an experiment in "what does
grcov consider to be coverage". Here's what I've found out...
* In grcov's eyes, most #[derive(Foo)] lines count as containing code;
but calling any one derived function counts as calling those lines.
* Unlike with tarpaulin, it is actually possible to reach 100% grcov
line coverage. (Tarpaulin likes to pick "}" lines and tell you that
you never reached them; or sometimes it picks expression
statements that have the effect of a return, and tells you that
they're unreached. Even with these tests, tarpaulin claims that
the line coverage of tor-units is only 97.3%.)
* In rust, it may be a bit hopeless trying to get high function
coverage. Even though we've hit every line of the tor-units crate,
the function coverage from its own tests is only 9.38% (55.41%
from other crates). I think this is probably due to derived
functions, or maybe due to generics getting instantiated?
I've got no idea; the denominator for the function coverage
lines fluctuates oddly.
This change jettisons the awk and ed dependencies and instead uses a
real HTML parser, via the BeautifulSoup library in python.
Using BeautifulSoup lets us do trickier stuff, like actually
extracting the coverage totals and adding our own table, with
per-crate coverage.
The script only does this post-processing when it finds python3; the
script exits with an error if BeautifulSoup isn't installed.
The sane_defaults() call is now the same as you get from a default
builder: by convention, we just call that method Default::default().
The with_directories() constructor makes more sense as a constructor
for the TorClientConfigBuilder than for TorClientConfig.
