This does not work as-is ("CSI a" is shift-up, not up).
I'm not sure if we want to implement these.
It's not a regression so there is no pressure.
This reverts commit 350598cb99.
byte_to_symbol was broken because it didn't iterate by byte, it
iterated by rust-char, which is a codepoint.
So it failed for everything outside of ascii and, because of a
mistaken bound, ascii chars from 0x21 to 0x2F ("!" to "/" - all the punctuation).
char_to_symbol will print printable codepoints as-is and
others escaped. This is okay - something like `decoded from: +` or
`decoded from: ö` is entirely understandable, there is no need to tell
you that "ö" is \xc3\xb6.
This reverts commit 423e5f6c03.
This except clause was too narrow, so it would fail here even on other
systems just because webbrowser.get() returned nothing usable
Now it will fail *later* with "could not locate runnable browser", but
at least it won't say anything about chromeos on non-chromeos systems.
Array starts at 0, goes up to 27, that's 28 entries... *BUT* we also
need the catch-all entry after, so it's 29.
To be honest there's got to be a better way to write this.
WezTerm supports CSI u but unfortunately, typing single quote on a German
keyboard makes WezTerm send what gets decoded as `shift-'`.
This is bad, so disable it until this is fixed. In future we should maybe
add a runtime option to allow the user to override this decision.
See #10663
The \e\e\[A style is bad but iTerm and putty (alt-left) use it.
The main motivation for this change is to improve fish_key_reader output.
Part of #10663
As of rust 1.78, the Unix stdlib implementation is affected by the same issue:
pub fn sleep(dur: Duration) {
let mut secs = dur.as_secs();
let mut nsecs = dur.subsec_nanos() as _;
// If we're awoken with a signal then the return value will be -1 and
// nanosleep will fill in `ts` with the remaining time.
unsafe {
while secs > 0 || nsecs > 0 {
let mut ts = libc::timespec {
tv_sec: cmp::min(libc::time_t::MAX as u64, secs) as libc::time_t,
tv_nsec: nsecs,
};
secs -= ts.tv_sec as u64;
let ts_ptr = core::ptr::addr_of_mut!(ts);
if libc::nanosleep(ts_ptr, ts_ptr) == -1 {
assert_eq!(os::errno(), libc::EINTR);
secs += ts.tv_sec as u64;
nsecs = ts.tv_nsec;
} else {
nsecs = 0;
}
}
}
}
Note that there is a small behavior change here -- sleep() will continue
after signals; I'm not sure if we want that but it seems harmless?
Part of #10634
iTerm2 deviates from protocol, so back out c3c832761 (Stop using stack for
kitty progressive enhancement, 2024-08-03) in that case.
Note that we use several ways of detecting iTerm2 (ITERM_PROFILE,
TERM_PROGRAM=iTerm.app, ITERM_SESSION_ID).
LC_TERMINAL seems superior because it works over ssh.
This new one should hopefully go away eventually.
- Ubuntu focal is the lowest LTS release that we can support with only
distro packages (e.g. no rustup).
- Remove tsan from Cirrus (it's not working currently, and also not really
important).
- Remove Centos (it passes tests but I'm not sure it's worth adding; there
isn't even an official docker image for CentOS Stream).
