Changelog
Cargo 1.36 (2019-07-04)
Added
- (Nightly only): Added
-Z install-upgrade
feature to track details about installed crates and to automatically update them if they are out-of-date. #6798 - (Nightly only): Added the
public-dependency
feature which allows tracking public versus private dependencies. #6772
Changed
publish = ["crates-io"]
may be added to the manifest to restrict publishing to crates.io only. #6838- macOS: Only include the default paths if
DYLD_FALLBACK_LIBRARY_PATH
is not set. Also, remove/lib
from the default set. #6856 cargo publish
will now exit early if the login token is not available. #6854- HTTP/2 stream errors are now considered "spurious" and will cause a retry. #6861
- (Nightly only): The
publish-lockfile
feature has had some significant changes. The default is nowtrue
, theCargo.lock
will always be published for binary crates. TheCargo.lock
is now regenerated during publishing.cargo install
now ignores theCargo.lock
file by default, and requires--locked
to use the lock file. Warnings have been added if yanked dependencies are detected. #6840 - Setting a feature on a dependency where that feature points to a required dependency is now an error. Previously it was a warning. #6860
- Resolver performance improvements for some cases. #6853
Fixed
- More carefully track the on-disk fingerprint information for dependencies. This can help in some rare cases where the build is interrupted and restarted. #6832
cargo run
now correctly passes non-UTF8 arguments to the child process. #6849
Cargo 1.35 (2019-05-23)
Added
- Added the
rustc-cdylib-link-arg
key for build scripts to specify linker arguments for cdylib crates. #6298 - (Nightly only):
cargo clippy-preview
is now a built-in cargo command. #6759
Changed
- When passing a test filter, such as
cargo test foo
, don't build examples (unless they settest = true
). #6683 - Forward the
--quiet
flag fromcargo test
to the libtest harness so that tests are actually quiet. #6358 - The verification step in
cargo package
that checks if any files are modified is now stricter. It uses a hash of the contents instead of checking filesystem mtimes. It also checks all files in the package. #6740 - Jobserver tokens are now released whenever Cargo blocks on a file lock. #6748
- Issue a warning for a previous bug in the TOML parser that allowed multiple table headers with the same name. #6761
- Removed the
CARGO_PKG_*
environment variables from the metadata hash and added them to the fingerprint instead. This means that when these values change, stale artifacts are not left behind. Also added the "repository" value to the fingerprint. #6785 cargo metadata
no longer shows anull
field for a dependency without a library inresolve.nodes.deps
. The dependency is no longer shown. #6534cargo new
will no longer include an email address in theauthors
field if it is set to the empty string. #6802cargo doc --open
now works when documenting multiple packages. #6803cargo install --path P
now loads the.cargo/config
file from the directory P. #6805- Using semver metadata in a version requirement (such as
1.0.0+1234
) now issues a warning that it is ignored. #6806 cargo install
now rejects certain combinations of flags where some flags would have been ignored. #6801- (Nightly only): The
build-override
profile setting now includes proc-macros and their dependencies. #6811 - Resolver performance improvements for some cases. #6776
- (Nightly only): Optional and target dependencies now work better with
-Z offline
. #6814
Fixed
- Fixed running separate commands (such as
cargo build
thencargo test
) where the second command could use stale results from a build script. #6720 - Fixed
cargo fix
not working properly if a.gitignore
file that matched the root package directory. #6767 - Fixed accidentally compiling a lib multiple times if
panic=unwind
was set in a profile. #6781 - Paths to JSON files in
build.target
config value are now canonicalized to fix building dependencies. #6778 - Fixed re-running a build script if its compilation was interrupted (such as if it is killed). #6782
- Fixed
cargo new
initializing a fossil repo. #6792 - Fixed supporting updating a git repo that has a force push when using the
git-fetch-with-cli
feature.git-fetch-with-cli
also shows more error information now when it fails. #6800 --example
binaries built for the WASM target are fixed to no longer include a metadata hash in the filename, and are correctly emitted in thecompiler-artifact
JSON message. #6812
Cargo 1.34 (2019-04-11)
Added
- 🔥 Stabilized support for alternate registries. #6654
- (Nightly only): Added
-Z mtime-on-use
flag to cause the mtime to be updated on the filesystem when a crate is used. This is intended to be able to track stale artifacts in the future for cleaning up unused files. #6477 #6573 - Added documentation on using builds.sr.ht Continuous Integration with Cargo. #6565
Cargo.lock
now includes a comment at the top that it is@generated
. #6548- Azure DevOps badges are now supported. #6264
- (Nightly only): Added experimental
-Z dual-proc-macros
to build proc macros for both the host and the target. #6547 - Added a warning if
--exclude
flag specifies an unknown package. #6679
Changed
cargo test --doc --no-run
doesn't do anything, so it now displays an error to that effect. #6628- Various updates to bash completion: add missing options and commands,
support libtest completions, use rustup for
--target
completion, fallback to filename completion, fix editing the command line. #6644 - Publishing a crate with a
[patch]
section no longer generates an error. The[patch]
section is removed from the manifest before publishing. #6535 build.incremental = true
config value is now treated the same asCARGO_INCREMENTAL=1
, previously it was ignored. #6688- Errors from a registry are now always displayed regardless of the HTTP response code. #6771
Fixed
- Fixed bash completion for
cargo run --example
. #6578 - Fixed a race condition when using a local registry and running multiple cargo commands at the same time that build the same crate. #6591
- Fixed some flickering and excessive updates of the progress bar. #6615
- Fixed a hang when using a git credential helper that returns incorrect credentials. #6681
- Fixed resolving yanked crates with a local registry. #6750
Cargo 1.33 (2019-02-28)
Added
compiler-artifact
JSON messages now include an"executable"
key which includes the path to the executable that was built. #6363- The man pages have been rewritten, and are now published with the web documentation. #6405
- (Nightly only): Allow using registry names in
[patch]
tables instead of just URLs. #6456 cargo login
now displays a confirmation after saving the token. #6466- A warning is now emitted if a
[patch]
entry does not match any package. #6470 cargo metadata
now includes thelinks
key for a package. #6480- (Nightly only):
cargo metadata
added theregistry
key for dependencies. #6500 - "Very verbose" output with
-vv
now displays the environment variables that cargo sets when it runs a process. #6492 --example
,--bin
,--bench
, or--test
without an argument now lists the available targets for those options. #6505- Windows: If a process fails with an extended status exit code, a human-readable name for the code is now displayed. #6532
- Added
--features
,--no-default-features
, and--all-features
flags to thecargo package
andcargo publish
commands to use the given features when verifying the package. #6453
Changed
- If
cargo fix
fails to compile the fixed code, the rustc errors are now displayed on the console. #6419 - (Nightly only): Registry names are now restricted to the same style as
package names (alphanumeric,
-
and_
characters). #6469 - (Nightly only):
cargo login
now displays the/me
URL from the registry config. #6466 - Hide the
--host
flag fromcargo login
, it is unused. #6466 - (Nightly only):
cargo login --registry=NAME
now supports interactive input for the token. #6466 - (Nightly only): Registries may now elide the
api
key fromconfig.json
to indicate they do not support API access. #6466 - Build script fingerprints now include the rustc version. #6473
- macOS: Switched to setting
DYLD_FALLBACK_LIBRARY_PATH
instead ofDYLD_LIBRARY_PATH
. #6355 RUSTFLAGS
is now included in the metadata hash, meaning that changing the flags will not overwrite previously built files. #6503- When updating the crate graph, unrelated yanked crates were erroneously
removed. They are now kept at their original version if possible. This was
causing unrelated packages to be downgraded during
cargo update -p somecrate
. #5702 - TOML files now support the 0.5 TOML syntax.
Fixed
cargo fix
will now ignore suggestions that modify multiple files. #6402cargo fix
will now only fix one target at a time, to deal with targets which share the same source files. #6434- (Nightly only): Fixed panic when using
--message-format=json
with metabuild. #6432 - Fixed bash completion showing the list of cargo commands. #6461
cargo init
will now avoid creating duplicate entries in.gitignore
files. #6521- (Nightly only): Fixed detection of publishing to crates.io when using alternate registries. #6525
- Builds now attempt to detect if a file is modified in the middle of a compilation, allowing you to build again and pick up the new changes. This is done by keeping track of when the compilation starts not when it finishes. Also, #5919 was reverted, meaning that cargo does not treat equal filesystem mtimes as requiring a rebuild. #6484
Cargo 1.32 (2019-01-17)
Added
- (Nightly only): Allow usernames in registry URLs. #6242
- Registries may now display warnings after a successful publish. #6303
- Added a glossary to the documentation. #6321
- Added the alias
c
forcargo check
. #6218 - (Nightly only): Added
"compile_mode"
key to the build-plan JSON structure to be able to distinguish running a custom build script versus compiling the build script. #6331
Changed
- 🔥 HTTP/2 multiplexing is now enabled by default. The
http.multiplexing
config value may be used to disable it. #6271 - Use ANSI escape sequences to clear lines instead of spaces. #6233
- Disable git templates when checking out git dependencies, which can cause problems. #6252
- Include the
--update-head-ok
git flag when using thenet.git-fetch-with-cli
option. This can help prevent failures when fetching some repositories. #6250 - When extracting a crate during the verification step of
cargo package
, the filesystem mtimes are no longer set, which was failing on some rare filesystems. #6257 crate-type = ["proc-macro"]
is now treated the same asproc-macro = true
inCargo.toml
. #6256- An error is raised if
dependencies
,features
,target
, orbadges
is set in a virtual workspace. Warnings are displayed ifreplace
orpatch
is used in a workspace member. #6276 - Improved performance of the resolver in some cases. #6283 #6366
.rmeta
files are no longer hard-linked into the base target directory (target/debug
). #6292- A warning is issued if multiple targets are built with the same output filenames. #6308
- When using
cargo build
(without--release
) benchmarks are now built using the "test" profile instead of "bench". This makes it easier to debug benchmarks, and avoids confusing behavior. #6309 - User aliases may now override built-in aliases (
b
,r
,t
, andc
). #6259 - Setting
autobins=false
now disables auto-discovery of inferred targets. #6329 cargo verify-project
will now fail on stable if the project uses unstable features. #6326- Platform targets with an internal
.
within the name are now allowed. #6255 cargo clean --release
now only deletes the release directory. #6349
Fixed
- Avoid adding extra angle brackets in email address for
cargo new
. #6243 - The progress bar is disabled if the CI environment variable is set. #6281
- Avoid retaining all rustc output in memory. #6289
- If JSON parsing fails, and rustc exits nonzero, don't lose the parse failure message. #6290
- (Nightly only):
--out-dir
no longer copies over build scripts. #6300 - Fixed renaming a project directory with build scripts. #6328
- Fixed
cargo run --example NAME
to work correctly if the example setscrate_type = ["bin"]
. #6330 - Fixed issue with
cargo package
git discovery being too aggressive. The--allow-dirty
now completely disables the git repo checks. #6280 - Fixed build change tracking for
[patch]
deps which resulted incargo build
rebuilding when it shouldn't. #6493
