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.
  • file-package: Map file paths to fully qualified package names.
  • 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: Read and display buckconfig values.
  • 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

Common Options:​

Common options are documented on the Common Options page.

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.

Common Options:​

Common options are documented on the Common Options page.

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

  • --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.

  • --profile-patterns <PROFILE_PATTERNS> Enables profiling for all evaluations whose evaluation identifier matches one of the provided patterns.

    Some examples identifiers: analysis/cell//buck2/app/buck2_action_impl:buck2_action_impl (cfg:linux-x86_64#27ac5723e0c99706) load/cell//build_defs/json.bzl load/prelude//playground/test.bxl load/cell//build_defs/json.bzl@other_cell load_buildfile/fbcode//third-party-buck/platform010/build/ncurses load_packagefile/fbcode//cli/rust/cli_delegate anon_analysis/anon//:_anon_link_rule (anon: 766183dc9b6f680a) (fbcode//buck2/platform/execution:linux-x86_64#08961b14cfb182aa) bxl/prelude//playground/test.bxl:playground

    You can pass --profile-patterns=.* to enable no-op profiling for everything (additionally pass --profile-patterns-mode=none to use no-op profiling to just get a list of all the identifiers).

    The profile results will be written to individual .profile files in <ROOT_OUTPUT>/<data+time>-<uuid>/ where ROOT_OUTPUT comes from the --profile-patterns-output flag. In that directory there will also be a file listing all the identifiers that were profiled.

    Enabling/disabling profiling of an evaluation will invalidate the results of that evaluation and it will be recomputed. In some cases, this will cause other work to also need to be redone (for example, invalidating the result of loading PACKAGE files causes all consumers to be recomputed). But if you keep profiling options consistent between commands, only the work that is otherwise invalidated will be redone (and only for those would profiling results be created).

    You must also pass --profile-patterns-mode and --profile-patterns-output.

  • --profile-patterns-output <PATH>

  • --profile-patterns-mode <PROFILE_PATTERNS_MODE> Profile mode.

    Memory profiling modes have suffixes either -allocated or -retained.

    -retained means memory kept in frozen starlark heaps after analysis completes. -retained does not work when profiling loading, because no memory is retained after loading and frozen heap is not even created. This is probably what you want when profiling analysis.

    -allocated means allocated memory, including memory which is later garbage collected.

    • Possible values:
      • time-flame
      • heap-allocated
      • heap-retained
      • heap-flame-allocated

buck2 audit providers​

prints out the providers for a target pattern

Usage: buck2 audit providers [OPTIONS] <TARGET_PATTERNS>...

Arguments:​

  • <TARGET_PATTERNS> Patterns to analyze

Common options are documented on the Common Options page.

Options:​

  • --quiet

  • -l, --list List the available providers

  • --print-debug Print the providers using debug format (very verbose)

  • -u, --target-universe <TARGET_UNIVERSE> Comma separated list of targets to construct a configured target universe.

    When the option is specified, command targets are be resolved in this universe. Additionally, --target-platforms= and --modifier= flags are be used to configure the universe targets, not the command targets.

    This argument is particularly recommended on most non-trivial cqueries. In the absence of this argument, buck2 will use the target literals in your cquery expression as the value for this argument, which may not be what you want.

  • --target-platforms <PLATFORM> Configuration target (one) to use to configure targets

  • -m, --modifier <VALUE> A configuration modifier to configure all targets on the command line. This may be a constraint value target.

    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.

  • --profile-patterns <PROFILE_PATTERNS> Enables profiling for all evaluations whose evaluation identifier matches one of the provided patterns.

    Some examples identifiers: analysis/cell//buck2/app/buck2_action_impl:buck2_action_impl (cfg:linux-x86_64#27ac5723e0c99706) load/cell//build_defs/json.bzl load/prelude//playground/test.bxl load/cell//build_defs/json.bzl@other_cell load_buildfile/fbcode//third-party-buck/platform010/build/ncurses load_packagefile/fbcode//cli/rust/cli_delegate anon_analysis/anon//:_anon_link_rule (anon: 766183dc9b6f680a) (fbcode//buck2/platform/execution:linux-x86_64#08961b14cfb182aa) bxl/prelude//playground/test.bxl:playground

    You can pass --profile-patterns=.* to enable no-op profiling for everything (additionally pass --profile-patterns-mode=none to use no-op profiling to just get a list of all the identifiers).

    The profile results will be written to individual .profile files in <ROOT_OUTPUT>/<data+time>-<uuid>/ where ROOT_OUTPUT comes from the --profile-patterns-output flag. In that directory there will also be a file listing all the identifiers that were profiled.

    Enabling/disabling profiling of an evaluation will invalidate the results of that evaluation and it will be recomputed. In some cases, this will cause other work to also need to be redone (for example, invalidating the result of loading PACKAGE files causes all consumers to be recomputed). But if you keep profiling options consistent between commands, only the work that is otherwise invalidated will be redone (and only for those would profiling results be created).

    You must also pass --profile-patterns-mode and --profile-patterns-output.

  • --profile-patterns-output <PATH>

  • --profile-patterns-mode <PROFILE_PATTERNS_MODE> Profile mode.

    Memory profiling modes have suffixes either -allocated or -retained.

    -retained means memory kept in frozen starlark heaps after analysis completes. -retained does not work when profiling loading, because no memory is retained after loading and frozen heap is not even created. This is probably what you want when profiling analysis.

    -allocated means allocated memory, including memory which is later garbage collected.

buck2 audit subtargets​

Print all subtargets

Usage: buck2 audit subtargets [OPTIONS] <TARGET_PATTERNS>...

Arguments:​

  • <TARGET_PATTERNS> Patterns to analyze

Common Options:​

Common options are documented on the Common Options page.

Options:​

  • --json Print subtargets as JSON

  • -u, --target-universe <TARGET_UNIVERSE> Comma separated list of targets to construct a configured target universe.

    When the option is specified, command targets are be resolved in this universe. Additionally, --target-platforms= and --modifier= flags are be used to configure the universe targets, not the command targets.

    This argument is particularly recommended on most non-trivial cqueries. In the absence of this argument, buck2 will use the target literals in your cquery expression as the value for this argument, which may not be what you want.

buck2 audit deferred-materializer​

Access and interact with the deferred materializer

Usage: buck2 audit deferred-materializer [OPTIONS] <COMMAND>

Subcommands:​

  • list
  • list-subscriptions
  • fsck
  • refresh
  • get-refresh-log: Get the log for TTL refreshes
  • test-iter
  • flush-access-times

Common Options:​

Common options are documented on the Common Options page.

Options:​

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

  • --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.

  • --profile-patterns <PROFILE_PATTERNS> Enables profiling for all evaluations whose evaluation identifier matches one of the provided patterns.

    Some examples identifiers: analysis/cell//buck2/app/buck2_action_impl:buck2_action_impl (cfg:linux-x86_64#27ac5723e0c99706) load/cell//build_defs/json.bzl load/prelude//playground/test.bxl load/cell//build_defs/json.bzl@other_cell load_buildfile/fbcode//third-party-buck/platform010/build/ncurses load_packagefile/fbcode//cli/rust/cli_delegate anon_analysis/anon//:_anon_link_rule (anon: 766183dc9b6f680a) (fbcode//buck2/platform/execution:linux-x86_64#08961b14cfb182aa) bxl/prelude//playground/test.bxl:playground

    You can pass --profile-patterns=.* to enable no-op profiling for everything (additionally pass --profile-patterns-mode=none to use no-op profiling to just get a list of all the identifiers).

    The profile results will be written to individual .profile files in <ROOT_OUTPUT>/<data+time>-<uuid>/ where ROOT_OUTPUT comes from the --profile-patterns-output flag. In that directory there will also be a file listing all the identifiers that were profiled.

    Enabling/disabling profiling of an evaluation will invalidate the results of that evaluation and it will be recomputed. In some cases, this will cause other work to also need to be redone (for example, invalidating the result of loading PACKAGE files causes all consumers to be recomputed). But if you keep profiling options consistent between commands, only the work that is otherwise invalidated will be redone (and only for those would profiling results be created).

    You must also pass --profile-patterns-mode and --profile-patterns-output.

  • --profile-patterns-output <PATH>

  • --profile-patterns-mode <PROFILE_PATTERNS_MODE> Profile mode.

    Memory profiling modes have suffixes either -allocated or -retained.

    -retained means memory kept in frozen starlark heaps after analysis completes. -retained does not work when profiling loading, because no memory is retained after loading and frozen heap is not even created. This is probably what you want when profiling analysis.

    -allocated means allocated memory, including memory which is later garbage collected.

    • Possible values:
      • time-flame
      • heap-allocated
      • heap-retained
      • heap-flame-allocated
      • heap-flame-retained
      • heap-summary-allocated

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.

Usage: buck2 audit output [OPTIONS] <OUTPUT_PATH>

Arguments:​

  • <OUTPUT_PATH> The buck-out path to the build artifact, starting with buck-out and including the configuration platform.

Common Options:​

Common options are documented on the Common Options page.

Options:​

  • --json

  • -A, --output-all-attributes Output all attributes, equivalent of --output-attribute ''.

    Avoid using this flag in automation because it may be expensive to produce certain attributes, and because it makes harder to track which special attributes are used.

  • -B, --output-basic-attributes Output basic attributes, namely those the user can supply, plus rule type and package name

  • -a, --output-attribute <ATTRIBUTE> Regular expressions to match attributes. Regular expressions are used in "search" mode, so for example empty string matches all attributes including special attributes.

    When using in automation, please specify the regular expression to match the attribute precisely, for example --output-attribute '^headers$' to make it easier to track which special attributes are used.

  • --output-attributes <ATTRIBUTE> Deprecated: Use --output-attribute instead.
