Test support for writing Pants plugins.
Project description
Pants is an Apache2 licensed build tool written in Python and Rust.
The latest documentation can be found at pantsbuild.org.
2.16.x Release Series
What's New
BUILD files
The new env function in BUILD files allows access to environment variables in BUILD files.
Run pants help symbols for documentation of all builtin symbols and macros provided by prelude files
which are usable in BUILD files.
The visibility rules syntax now supports matching on target names. The rules glob syntax also now uses the same syntax as target selectors.
Backends
Docker
The {pants.hash}
generation code was changed such that the generated hash for the same input will be different in pants 2.16.
Python
The Python backend added or improved support for various tools including:
-
pydocstyleis now supported for linting Python doc strings. Enable thepants.backend.python.lint.pydocstylebackend to add this support. -
ruffis now supported for linting and formatting Python code. Enable thepants.backend.experimental.python.lint.ruffbackend to add this support. -
pyenvis now supported as a way for Pants to provide a hermetic version of Python for each relevant Interpreter required to run user code. Enable thepants.backend.python.providers.experimental.pyenvbackend to add this support. -
Pants now understands how to parse dependencies of projects using the OpenStack/Stevedore ((https://github.com/openstack/stevedore) project. Enable the
pants.backend.python.framework.stevedorebackend to add this support. -
More Python target types now have the
environmentfield and thus can execute in non-local environments.
Deprecations:
-
The default value of
CPython>=3.7,<4for the[python].interpreter_constraintsoption is now deprecated and will be removed in Pants v2.17.x. This options sets Python interpreter constraints for Python-related targets which did not otherwise specify their own interpreter constraints. Instead of relying on this default, explicitly set the[python].interpreter_constraintsoption appropriately. We recommend constraining to a single interpreter minor version if you can, e.g.,interpreter_constraints = ['==3.11.*'], or at least a small number of interpreter minor versions, e.g.,interpreter_constraints = ['>=3.10,<3.12']. -
The special Python "tool lockfile" functionality is deprecated. Repos can now use regular "user lockfiles" to provide custom versions of tools.
Shell command improvements and support for ad-hoc tools
The Shell backend along with the new pants.backend.experimental.adhoc backend have received a number of improvements so that
Pants is able to invoke workflows that include tools for which Pants does not yet have a
dedicated backend.
In recognition of these improvements, the experimental_shell_command and experimental_run_shell_command target
types have graduated to no longer have the experimental_ prefix; use shell_command and run_shell_command
respectively instead.
The improvements include:
-
The
shell_commandcontinues to provide a way to run a tool for its side effects and capture outputs from the tool invocation for consumption as dependencies by other target types, but has had several improvements:- the
dependenciesfield has been deprecated, and separated into three fields:execution_dependenciesfor dependencies required to execute the command,output_dependenciesfor dependencies required to use the output, andrunnable_dependenciesfor targets that need to exist as directly executable on the sandbox'sPATH - the
outputsfield has been separated intooutput_filesandoutput_directories - the directory in which the command is invoked can be controlled via the new
workdirfield - the location of the output files when consumed as a dependency can be controlled via the new
root_output_directoryfield
- the
-
Preserving symlinks as symlinks in process output, rather than resolving them to their target file. This eliminates the need for work-arounds in
shell_commands that happen to generate semantically-relevant symlinks, such as the contents ofnode_modules/.binif usingshell_commandto invokenpm ciornpm install. -
The new
adhoc_tooltarget type supplied by theadhocbackend allows executing most "runnable" target types (those supported forpants rungoal) exported by another Pants backend in an execution sandbox goal, allowing you to capture their outputs to be captured. The outputs can then be consumed by another Pants target in a similar manner to theshell_commandtarget type. "Runnable" target types include:- Adhoc:
system_binary - Docker:
docker_image - Go:
go_binary - JVM:
jvm_artifact, anddeploy_jar - Python:
pex_binary,python_requirement,python_source, andpyoxidizer_binary
- Adhoc:
-
The new
system_binarytarget type supplied by theadhocbackend wraps any externally-managed tool so that the tool may be invoked as a "runnable" by theadhoc_tooltarget type, while also allowing tool versions to be pinned for reproducibility. -
Support for running in non-local environments as specified by the
environmentfield onshell_command,adhoc_tool, and related target types. -
Defining arbitrary shell commands as tests which can be invoked using
pants testvia the newexperimental_test_shell_commandtarget type. -
The
workdirfield torun_shell_commandhas been switched to match the documented behavior: it now runs from the same directory as theBUILDfile by default. To preserve the old behavior, explicitly setworkdir="/". The stabilisation also fixes other bugs with relative paths passed to theworkdirfield and thus may require updates.
Ad-hoc tool support, with the adhoc_tool or shell_command targets, can be used to compile third party
libraries in unsupported languages, run tools from ecosystems Pants doesn't yet directly support, and other similar code-generation tasks.
These targets can be used for first-party code generation, making use of existing backends that define
"runnable" targets if needed. For instance, exporting a OpenAPI schema from a Python API server, letting Pants
manage the interpreters and dependencies required.
Enable the pants.backend.experimental.adhoc backend to add the features supplied by the adhoc backend.
Enable the pants.backend.shell backend for the shell-related functionality including shell_command and
run_shell_command target types.
Go
The Go backend has received a large number of changes in order to be ready for Go v1.20 and to make continued progress on stabilizing the Go backend.
The main change is that Pants will now compile Go SDK packages from scratch and no longer rely on the prebuilt package archives distributed with the Go SDK. Go v1.20 will no longer ship with those prebuilt package archives, and so this change was necessary for Pants to continue to work with Go v1.20 and later releases. (It is also a correctness issue since Pants will now be able to apply compiler options consistently to both first-party Go code and Go SDK packages.)
The Pants team would appreciate if the community could try out 2.16.x with your Go code as an additional check to ensure there are no regressions.
The Go backend also now supports:
- Environments are supported via the
environmentfield available now ongo_binarytargets. - Code coverage can now analyze coverage for packages beyond just the package under test via the new
--go-test-cover-packagesoption. - Numerous bug fixes to the Cgo support.
- The data race detector is supported via the
racefield now available ongo_binarytargets. - Compiler and other flags may be set via the
compiler_flags,linker_flags, andassembler_flagsfields available on various target types.
Buf
Pants is now able to discover and supply configuration files for the Buf protobuf linter.
New: Preamble
The new "preamble" plugin allows formatting/linting files to ensure they start with specific text, such as a copyright header. Enable the
pants.backend.tools.preamble backend to add this support.
New: CUE
Pants now have basic support for the CUE language for defining, generating, and validating configuration data.
Enable the pants.backend.experimental.cue backend to use this support.
New: YamlLint
Pants now the supports the yamllint linter for YAML files. Enable the pants.backend.experimental.tools.yamllint backend to add this support.
New: AWS S3 support for URLs
Pants now supports referencing S3 URLs via the scheme (E.g. s3://), or authority (E.g. *.s3*amazonaws.com or s3.*amazonaws.com)
anywhere a URL can be specified.
Credentials are loaded similar to the AWS CLI (most regularly ~/.aws/credentials) and attached as headers in the request (which aren't cached or logged).
Enable the pants.backend.url_handlers.s3 backend to add this support.
New
Plugin API Changes
The URLDownloadHandler union has been added to allow plugins to modify native URL downloading, such as transforming the URL or attaching headers for auth.
The frozen_after_init decorator on dataclasses has been removed from many parts of the Pants codebase. Plugin authors should avoid use of this decorator because it will likely be removed in a future Pants version.
The deprecated Platform.current has been removed. Instead, have the affected rules take a Platform directly as a parameter and the engine will supply the relevant Platform instance.
The ToolCustomLockfile and ToolDefaultLockfile classes have been removed.
