Changelog

v0.6.9

Added

  • Added flags --term-old and --term-new to allow custom messages when bisecting a regression. #330 #339

Changed

  • Updated dependencies. #314 #313 #315 #319 #326 #327 #329 #340
  • No longer defaults to cross-compile mode when --target is not specified. This more closely matches cargo's behavior, which can affect reproducability. #323
  • Removed LTO and stripping of building cargo-bisect-rustc itself. #334

Fixed

  • Don't assume the date before the regressed nightly is the good nightly if there are missing nightlies. #320
  • Fixed building cargo-bisect-rustc itself to avoid unnecessary build-script rebuilds. #324
  • Fixed doc-change example documentation. #336
  • Replaced a panic with an error message if a given SHA commit is not from bors using the GitHub backend. #318
  • Fixed determination of what the latest nightly is when --end is not specified, and it is past UTC midnight, but the release process has not yet finished. #325
  • Fixed panic with --by-commit but no --start. #325

v0.6.8

Added

  • Added documentation for --alt builds. #289

Changed

Fixed

  • Fixed an issue when attempting to bisect a rollup, but the perf commits have been garbage collected, to display information about the rollup so that you can see which PRs were involved. #298

v0.6.7

Changed

Fixed

  • Fix bisecting into rollups via unrolled perf builds #280

v0.6.6

Added

  • 🎉 Added bisecting of rollups. This depends on the artifacts generated for rustc-perf which is only available for x86_64-unknown-linux-gnu. #256
  • 🎉 Added a new User Guide with more detailed documentation and a set of examples illustrating different ways to use cargo-bisect-rustc. The guide is available at https://rust-lang.github.io/cargo-bisect-rustc/. #266

Changed

Fixed

  • Fixed bounds checking when --start or --end is not specified. #243
  • The remote tags are now fetched from the rust-lang/rust repo to ensure that tag boundaries (--start 1.65.0) work if the tag hasn't been downloaded. #263

v0.6.5

Changed

  • Stack overflow on any thread (not just 'rustc') is treated as an ICE. #194
  • Clap (the CLI argument processor) has been updated, which may result in some minor CLI output and parsing changes. #225 #229
  • The check for the Rust upstream remote in the git repository has been loosened to only scan for rust-lang/rust so that non-https remotes like git@github.com:rust-lang/rust.git will work. #235
  • The --script option will now look for a script in the current directory (so that it no longer requires the ./ prefix). #236 #238
  • Specifying --start without --end will default the end to be the current date. Previously it would use the date of whatever nightly is currently installed. #240

Fixed

  • Fixed using either cargo bisect-rustc (with a space) or cargo-bisect-rustc (with a dash). #187
  • Show the CLI help page if no arguments are passed. #206
  • The CLI argument validator for --script has been removed to allow running scripts on PATH. This also removes the --host validator which was not needed. #207
  • Fixed showing the full chain of errors instead of just the top-level one. #237

v0.6.4

Added

  • Added the --component option to choose optional components to install. #131
  • An estimate of the number of steps left to run is now displayed. #178

Changed

  • Various code refactorings and dependency updates. These shouldn't have significant noticeable changes. #151 #152 #153 #155 #156
  • The CARGO_BUILD_TARGET environment variable is now set with the target triple. #159
  • The default release profile now uses stripping and LTO to significantly reduce the binary size. #157
  • Bounds with tags like --start=1.62.0 are now translated to a nightly date instead of a master git commit. This allows using tags from releases more than 6 months old. #177

v0.6.3

Fixed

  • Fixed assumption that the rust-lang/rust remote repo is named "origin". #149

v0.6.2

Added

  • --start and --end now support git tags (like 1.59.0) to bisect between stable releases. #147

Changed

  • Stack overflow is now treated as an ICE. #142

v0.6.1

Added

  • Added --with-dev option to download rustc-dev component. #101
  • Added --timeout option to trigger a failure if compilation takes too long. #135

Changed

  • Use the git CLI to fetch the rust-lang/rust repo when looking for CI commits to improve performance. #130

Fixed

  • Fixed off-by-one error when examining the date of the local nightly toolchain. #113
  • Fixed issue with --preserve when linking the nightly toolchain leaving a stale link. #125

v0.6.0

Added

  • Support specifying the path to a rust-lang/rust clone at runtime with RUST_SRC_REPO

Changed

  • Make --with-cargo the default to allow bisecting past changes in rustc options. Add --without-cargo flag to use the old behavior.
  • Use an anonymous remote that always points to rust-lang/rust when refreshing repository

Fixed

  • Add nightly start and end date validations against the current date – previously would attempt to install nightly even if date was in the future
  • Verify that --test-dir is a directory instead of assuming it is and then panicking

v0.5.2

  • Fix: revert the revised internal compiler error definition in commit a3891cdd26d1c5d35257c351c7c86fa7e72604bb

  • Add support for optional --regress=non-error regression testing definition (default is --regress=error)
  • Update the remove function to use an explicit bisector string at the beginning of the path name
  • Update the remove function to guard against deleting state not managed by cargo-bisect-rustc
  • Edit short and long help strings to fit on a single line
