dathere/qsv 0.46.0

on GitHub

Added

• Added release nightly binaries - optimized for size and speed:
  • compiled with the current Rust nightly/unstable at the time of release.
  • stdlib is compiled from source, instead of using the pre-built stdlib. This ensures stdlib is compiled with all of qsv's release settings (link time optimization, opt-level, codegen-units, panic=abort, etc.). This is why we only have nightly release builds for select platforms (the platform of GitHub's action runners), as we need access to the "native hardware" and cannot cross-compile stdlib to other platforms.
  • set panic=abort - removing panic-handling/formatting and backtrace code, making for smaller binaries.
  • set RUSTFLAGS=-C target-cpu=native to enable use of additional CPU-level features.
  • enables unstable/nightly features on regex and rand crates, that unlock performance/SIMD features on those crates.
• Added testing on nightly to CI

Changed

• dedup: reduced memory footprint by half by writing directly to disk, rather than storing in working mem, before writing
• excel: show sheet name in message along with row count; let docopt take care of validating mandatory arguments
• More whirlwind tour improvements - how timings were collected, footnotes, etc.
• Bump github/codeql-action from 1 to 2 by @dependabot in #277
• Bump log from 0.4.16 to 0.4.17 by @dependabot in #278
• Bump whatlang from 0.15 to 0.16
• Make file extension processing case-insensitive in #280
• Added Caching section to Performance Tuning
• Added UTF-8 section to Performance Tuning

Removed

• removed unneeded header file for wcp.csv used in Whirlwind Tour, now that we have a well-formed wcp.csv
