This new feature in rsconf 0.2.0 resolves the compile-time warnings we get under
rustc 1.80+ about unrecognized cfg names by informing cargo of all valid cfg
names/values even when the cfg in question isn't enabled.
rustc 1.80 now complains about features not declared in Cargo.toml and cfg
keys/values not declared by build.rs to protect against typos or misuse (you
think you're using the right condition but you're not). See
rust-lang/cargo#10554 and rust-lang/rust#82450.
(We're not actually using TSAN under CI at this time, but I do want to re-enable
it at some point — especially if we get multithreaded execution going — using
the rust-native TSAN configuration.)
I'll be updating the `rsconf` crate and patching `build.rs` accordingly to also
handle the warnings about unknown cfg values, but tsan is a feature and not a
cfg and these can be dealt with in `Cargo.toml` directly.
We were passing a slice (and not a vec) to `CString::new()`, meaning it would
allocate a new Vec internally to hold the bytes.
Also document that the resulting CString will be silently truncated at the first
interior NUL.
The function was repeatedly calling `s.char_at(n)` which is O(1) only for UTF-32
strings (so not a problem at the moment). But it was also calling `hex_digit(n)`
twice for each `n` in the 3-digit case, causing unnecessary repeated parsing of
individual characters into their radix-16 numeric equivalents, which could be
avoided just by reusing the already calculated result.
CARGO_NET_GIT_FETCH_WITH_CLI uses the `git` executable instead of the rust
git2 crate/lib, which speeds things up and is known to resolve some issues
fetching the registry or individual crates.
This is to work around a specific issue with git-resident Cargo.toml
dependencies (e.g. terminfo) that keep randomly failing to download under macOS
CI.
We use this fallback value for FISH_BUILD_DIR when `cargo` is not
invoked from `cmake`, but we already have a cargo-defined build
directory and we shouldn't just decide to use $TARGET_MANIFEST_DIR/build
instead.
Tests pass locally!
We will continue to use the "normal" fish base directory detection when using
the CMake test harness which properly sets up a sandboxed $HOME for fish to use,
but when running source code tests with a bare `cargo test` we don't want to
write to the actual user's profile.
This also works around test failures when running `cargo test` under CI with a
locked-down $HOME directory (see #10474).
Prior to this change, signals.py attempted to generate Ctrl-C (SIGINT) by
sending \x03 to stdin. But with the change to use the CSI U sequence, Ctrl-C no
longer generates SIGINT.
Switch to sending SIGINT directly. Also switch up some of the sleep constants so
that a sleep command can't be confused with another one.
The test_history_formats test was reading from build/tests/ which is an artifact
of the cmake test runner. The source code tests should not depend on the cmake
test harness at all, so this is changed to read from the original test source in
the ./tests/ directory instead.
As documented in #10474, there are issues with 64-bit floating point rounding
under x86 targets without SSE2 extensions, where x87 floating point math causes
imprecise results.
Document the shortcoming and provide some version of the test that passes
regardless of architecture.
FISH_BUILD_DIR (nominally, ./build) is created by cmake. If you only check out
the project via git and then run `cargo build`, this directory won't exist and
many of the tests will fail.
%ld expects a 4-byte parameter on 32-bit architectures and an 8-byte parameter
on 64-bit architectures, but we supplied are trying to supply a 64-bit parameter
that would overflow 32-bit storage.
Use %lld instead which expects a `long long` parameter, which should be 8-bytes
under both architectures.
See #10474
I think given a local terminal running fish on a remote system, we can't
assume that an input sequence like \ea is sent all in one packet. (If we
could that would be perfect.)
Let's readd the default escape delay, to avoid a potential regression, but
make it only apply to raw escape bindings like "bind \e123". Treat sequences
like "bind escape,1,2,3" like regular sequences, so they can be bound on
all terminals.
This partially reverts commit b815319607.
Given "abbr foo something", the input sequence
foo<space><ctrl-z><space>
would re-expand the abbreviation on the second space which is surprising
because the cursor is not at or inside the command token. This looks to be
a regression from 00432df42 (Trigger abbreviations after inserting process
separators, 2024-04-13)
Happily, 69583f303 (Allow restricting abbreviations to specific commands
(#10452), 2024-04-24) made some changes that mean the bad commit seems no
longer necessary. Not sure why it works but I'll take it.
I think we can now call what we have in git better than the last
C++-based release, and you'll still need a C compiler to build it
because we still have some C code (libc.c).
