Update the pydoctheme.css file to add support for print media.
The code was adapted from the existing support for screens that are less than
700px wide, with the following changes:
- Remove the documents and sections index
- Remove the quick search
- Remove dead CSS code
Additionally, add section numbers and ensure that code blocks are never split
across multiple pages.
GNUInstallDirs is what defines CMAKE_INSTALL_FULL_BINDIR and such, so
the setting in Rust.cmake didn't work.
This also makes build.rs error out if any of these aren't defined
This would highlight `$var["foo"]` as an error because
parse_util_slice_length didn't advance the iterator.
There's got to be a nicer way to write this.
The C++ code implicitly relied on wrapping behavior.
There are probably more cases like this. Maybe we should disable
"overflow-checks" in release mode.
This would crash from the highlighter for something like
`PATH={$PATH[echo " "`
The underlying cause is that we use "char_at" which panics on
overread.
So instead this implements try_char_at and then just returns None.
The function `stat` as defined in `include/x86_64-linux-gnu/sys/stat.h`
marks its arguments as nonnull as in below. This UB causes crash in
release builds with variable `interpreter` assumed to be nonnull. Along
with failing stat returning nonzero value, this ultimately causes
`strlen` to be called with NULL as argument.
Definition of `stat`:
```
extern int stat (const char *__restrict __file,
struct stat *__restrict __buf) __THROW __nonnull ((1, 2));
```
Reproduce:
```
> # interp.c is any vaild single file C source
> gcc ./interp.c -Wl,--dynamic-linker=/bad -o interp
> echo './interp' > in.txt
> ./fish < in.txt
'./fish < in.txt' terminated by signal SIGSEGV (Address boundary error)
```

This is more correct - we don't want to change how we encode this
string in the middle of encoding it, and also happens to be a bit
faster in my benchmarks because this is actually a function call
according to valgrind.
We assume that you use something like hyperfine to run warmups, like
our driver script does.
This allows the script to be run e.g. in valgrind without being too
much of a pain in the gluteus.
Iterator::last() consumes the entire iterator, even for DoubleEndedIterator,
see https://github.com/rust-lang/rust/pull/28125#issuecomment-145070161
Because of this, "at_line_start()" took 90% of
fish_indent share/completions/git.fish
making it take 1000ms instead of 30 ms. Fix that.
Keep running tests serially to avoid breaking assumptions.
I think many of these tests can run in parallel and/or don't need test_init().
Use the safe variant everywhere, to get it done faster.
Here are the differences to the C++ version in fish_tests:
1. we don't need to chdir to repo root, cargo test already does.
2. we don't need srandom because we already use deterministic RNGs for tests.
3. we don't yet call asan_before_exit(). Not yet sure how to hook into
"cargo test" before exit.
This will allow to use "cargo test" for unit tests that depend on our
curses.rs.
This means that Rust.cmake depends on ConfigureChecks, so move that one to
the front.
