Previously you have to unpoison memory from the Rust, however Rust does
supports MSan, so let's simply use it.
But for this we need nightly Rust and recompile standard library.

LTO in Rust produces multiple definition of `rust_eh_personality' (and
few others), and to overcome this --allow-multiple-definition has been
added.
Query for benchmark:
SELECT ignore(BLAKE3(materialize('Lorem ipsum dolor sit amet, consectetur adipiscing elit'))) FROM numbers(1000000000) FORMAT `Null`
upstream : Elapsed: 2.494 sec. Processed 31.13 million rows, 249.08 MB (12.48 million rows/s., 99.86 MB/s.)
upstream + rust lto: Elapsed: 13.56 sec. Processed 191.9 million rows, 1.5400 GB (14.15 million rows/s., 113.22 MB/s.)
llvm BLAKE3 : Elapsed: 3.053 sec. Processed 43.24 million rows, 345.88 MB (14.16 million rows/s., 113.28 MB/s.)
Note, I thought about simply replacing it with BLAKE3 from LLVM, but:
- this will not solve LTO issues for Rust (and in future more libraries
could be added)
- it makes integrating_rust_libraries.md useless (and there is even blog
post)
So instead I've decided to add this quirk (--allow-multiple-definition)
to fix builds.

Right now fuzzy search is too smart for SQL, it even takes into account
the case, which should not be accounted (you don't want to type "SELECT"
instead of "select" to find the query).
And to tell the truth, I think too smart fuzzy searching for SQL queries
is not required, and is only harming.
Exact matching seems better algorithm for SQL, it is not 100% exact, it
splits by space, and apply separate matcher actually for each word.
Note, that if you think that "space is not enough" as the delimiter,
then you should first know that this is the delimiter only for the
input query, so to match "system.query_log" you can use "sy qu log"
(also you can disable exact mode by prepending "'" char).
But it ignores the case by default, and the behaviour what is expected
from the CaseMatching::Ignore.
TL;DR;
Just for the history I will describe what had been tried.
At first I tried CaseMatching::Ignore - it does not helps for
SkimV1/SkimV2/Clangd matches.
So I converted lines from the history and input query, to the lower
case. However this does not work for UPPER CASE, since only initial
portion of the query had been converted to the lower.
Then I've looked into skim/fuzzy-matcher crates code, and look for the
reason why CaseMatching::Ignore does not work, and found that there is
still a penalty for case mismatch, but there is no way to pass it from
the user code, so I've tried guerrilla to monkey patch the library's
code and it works:
// Avoid penalty for case mismatch (even with CaseMatching::Ignore)
let _guard = guerrilla::patch0(SkimScoreConfig::default, || {
let score_match = 16;
let gap_start = -3;
let gap_extension = -1;
let bonus_first_char_multiplier = 2;
return SkimScoreConfig{
score_match,
gap_start,
gap_extension,
bonus_first_char_multiplier,
bonus_head: score_match / 2,
bonus_break: score_match / 2 + gap_extension,
bonus_camel: score_match / 2 + 2 * gap_extension,
bonus_consecutive: -(gap_start + gap_extension),
// penalty_case_mismatch: gap_extension * 2,
penalty_case_mismatch: 0,
};
});
But this does not sounds like a trivial code, so I decided, to look
around, and realized that "exact" matching should do what is required
for the completion of queries (at least from my point of view).

In case of multi-line queries in the history, skim may leave some
symbols on the screen, which looks icky.

Due to we need to substitude config for Rust builds (see #44762 for
details), the source dir is copied to the binary dir, but this is done
only once, so to detect changes in sources you need to run cmake,
without this patch.

Our crates has configuration files:
- config for cargo (see config.toml.in)
- and possibly config for build (build.rs.in)
Previously it uses source directory, and it will overrides files in the
source directory, which will require recompile of crates in case of
multiple builds for one source directory.
To avoid overlaps different builds for one source directory, crate will
be copied from source directory to the binary directory.

This leads to the problem when you switch compiler flags, for example:
$ cmake -DSANITIZE=memory ..
$ ninja
$ cmake -DSANITIZE= ..
$ ninja
And this leads to:
ld.lld-15: error: undefined symbol: __msan_init
>>> referenced by lib.rs.cc
>>> lib.rs.o:(msan.module_ctor) in archive rust/skim/RelWithDebInfo/lib_ch_rust_skim_rust.a

Before this patch corrosion requires that CMAKE_BUILD_TYPE matches the
CMAKE_CONFIGURATION_TYPES, which is
"RelWithDebInfo;Debug;Release;MinSizeRel", so that said, that if you
were using CMAKE_BUILD_TYPE=debug, it will not work.

Note, that it can the fail the client if the skim itself will fail,
however I haven't seen it panicd, so let's try.
P.S. about adding USE_SKIM into configure header instead of just compile
option for target, it is better, because it allows not to recompile lots
of C++ headers, since we have to add skim library as PUBLIC. But anyway
this will be resolved in a different way, but separatelly.

Right now it works for host platforms because of gcc package, that
includes gcc-cross sysroot.
Use bundled sysroot from contrib instead.
