audit

This document provides an overview of the commands and options available under buck2 audit.

buck2 audit​

Perform lower level queries

Usage: buck2 audit <COMMAND>

Subcommands:​

  • cell: Query information about the [cells] list in .buckconfig.
  • classpath: Prints out a target's classpaths if it has one. This command is deprecated and currently available for compatibility with buck1. We will replace this command with something that can audit the entire TemplatePlaceholderInfo in the future.
  • config: buck audit config
  • configurations: prints the constraints for configuration IDs
  • includes: list build file extensions imported at parse time.
  • prelude: print the interpreter prelude to stdout
  • providers: prints out the providers for a target pattern
  • subtargets: Print all subtargets
  • analysis-queries: buck audit analysis resolving query attrs
  • execution-platform-resolution: prints out information about execution platform resolution
  • visibility: Verify the visibility for transitive deps of the specified target(s) on the unconfigured target graph
  • starlark: Debug Starlark interpreter
  • dep-files: prints out the select files for a command
  • deferred-materializer: Access and interact with the deferred materializer
  • output: Query the action that produced the output artifact. Does not support BXL, test, scratch, or anon artifacts. If the configuration hash of the output path does not match the current platform configuration, the unconfigured target label will be returned.
  • parse: Parses the buck-out path into parts that may be useful (ex: config hash, file path to artifact).
  • package-values: Inspect package values
  • perf: Commands for checking buck2 performance

buck2 audit cell​

Query information about the [cells] list in .buckconfig.

Usage: buck2 audit cell [OPTIONS] [CELL_ALIASES]...

Arguments:​

  • <CELL_ALIASES> Cell aliases to query. These aliases will be resolved in the working directory cell.

Options:​

  • --json Output in JSON format

  • --paths-only Don't include the cell name in the output

  • --aliases If enabled and no explicit aliases are passed, will query for all aliases in the working directory cell.

  • -m, --modifier <VALUE> This option is not used

  • -c, --config <SECTION.OPTION=VALUE> List of config options

  • --config-file <PATH> List of config file paths

  • --fake-host <HOST>

    • Possible values:
      • default
      • linux
      • macos
      • windows

  • --fake-arch <ARCH>

    • Possible values:
      • default
      • aarch64
      • x8664

  • --fake-xcode-version <VERSION-BUILD> Value must be formatted as: version-build (e.g., 14.3.0-14C18 or 14.1-14B47b)

  • --reuse-current-config Re-uses any --config values (inline or via modefiles) if there's a previous command, otherwise the flag is ignored.

    If there is a previous command and --reuse-current-config is set, then the old config is used, ignoring any overrides.

    If there is no previous command but the flag was set, then the flag is ignored, the command behaves as if the flag was not set at all.

  • --exit-when-different-state Used for exiting a concurrent command when a different state is detected

  • --preemptible <PREEMPTIBLE> Used to configure when this command could be preempted by another command for the same isolation dir.

    Normally, when you run two commands - from different terminals, say - buck2 will attempt to run them in parallel. However, if the two commands are based on different state, that is they either have different configs or different filesystem states, buck2 cannot run them in parallel. The default behavior in this case is to block the second command until the first completes.

    • Possible values:
      • never: (default) When another command starts that cannot run in parallel with this one, block that command
      • always: When another command starts, interrupt this command, even if they could run in parallel. There is no good reason to use this other than that it provides slightly nicer superconsole output
      • ondifferentstate: When another command starts that cannot run in parallel with this one, interrupt this command

  • --disable-starlark-types Disable runtime type checking in Starlark interpreter.

    This option is not stable, and can be used only locally to diagnose evaluation performance problems.

  • --stack Record or show target call stacks.

    Starlark call stacks will be included in duplicate targets error.

    If a command outputs targets (like targets command), starlark call stacks will be printed after the targets.

  • --console <super|simple|...> Which console to use for this command

    • Default value: auto
    • Possible values:
      • auto
      • none
      • simple
      • simplenotty
      • simpletty
      • super

  • --ui <UI> Configure additional superconsole ui components.

    Accepts a comma-separated list of superconsole components to add. Possible values are:

    dice - shows information about evaluated dice nodes debugevents - shows information about the flow of events from buckd

    These components can be turned on/off interactively. Press 'h' for help when superconsole is active.

    • Possible values:
      • dice
      • debugevents
      • io: I/O panel
      • re: RE panel

  • --no-interactive-console Disable console interactions

  • --event-log <PATH> Write events to this log file

  • --write-build-id <PATH> Write command invocation id into this file

  • --unstable-write-invocation-record <PATH> Write the invocation record (as JSON) to this path. No guarantees whatsoever are made regarding the stability of the format

  • --command-report-path <PATH> Write the command report to this path. A command report is always written to buck-out/v2/&lt;uuid&gt;/command_report even without this flag

buck2 audit classpath​

Prints out a target's classpaths if it has one. This command is deprecated and currently available for compatibility with buck1. We will replace this command with something that can audit the entire TemplatePlaceholderInfo in the future.

However, if the two commands are based on different state, that is they either have different configs or different filesystem states, buck2 cannot run them in parallel. The default behavior in this case is to block the second command until the first completes.

    • Possible values:
      • never: (default) When another command starts that cannot run in parallel with this one, block that command
      • always: When another command starts, interrupt this command, even if they could run in parallel. There is no good reason to use this other than that it provides slightly nicer superconsole output
      • ondifferentstate: When another command starts that cannot run in parallel with this one, interrupt this command

  • --disable-starlark-types Disable runtime type checking in Starlark interpreter.

    This option is not stable, and can be used only locally to diagnose evaluation performance problems.

  • --stack Record or show target call stacks.

    Starlark call stacks will be included in duplicate targets error.

    If a command outputs targets (like targets command), starlark call stacks will be printed after the targets.

  • --console <super|simple|...> Which console to use for this command

    • Default value: auto
    • Possible values:
      • auto
      • none

    Accepts a comma-separated list of superconsole components to add. Possible values are:

    dice - shows information about evaluated dice nodes debugevents - shows information about the flow of events from buckd

    These components can be turned on/off interactively. Press 'h' for help when superconsole is active.

    • Possible values:

  • --reuse-current-config Re-uses any --config values (inline or via modefiles) if there's a previous command, otherwise the flag is ignored.

    If there is a previous command and --reuse-current-config is set, then the old config is used, ignoring any overrides.
