PYTHON_VERSION_COMPATIBILITY: PY2+3

Recipe module to ensure a checkout is consistent on a bot.

#### **class [BotUpdateApi](/recipes/recipe_modules/bot_update/api.py#12)([RecipeApi][recipe_engine/wkt/RecipeApi]):**

&mdash; **def [\_\_call\_\_](/recipes/recipe_modules/bot_update/api.py#22)(self, name, cmd, \*\*kwargs):**

Wrapper for easy calling of bot_update.

&mdash; **def [deapply\_patch](/recipes/recipe_modules/bot_update/api.py#532)(self, bot_update_step):**

Deapplies a patch, taking care of DEPS and solution revisions properly.
    

&mdash; **def [ensure\_checkout](/recipes/recipe_modules/bot_update/api.py#79)(self, gclient_config=None, suffix=None, patch=True, update_presentation=True, patch_root=None, with_branch_heads=False, with_tags=False, no_fetch_tags=False, refs=None, patch_oauth2=None, oauth2_json=None, use_site_config_creds=None, clobber=False, root_solution_revision=None, rietveld=None, issue=None, patchset=None, gerrit_no_reset=False, gerrit_no_rebase_patch_ref=False, assert_one_gerrit_change=True, disable_syntax_validation=False, patch_refs=None, ignore_input_commit=False, add_blamelists=False, set_output_commit=False, step_test_data=None, enforce_fetch=False, \*\*kwargs):**

Args:
  * gclient_config: The gclient configuration to use when running bot_update.
    If omitted, the current gclient configuration is used.
  * no_fetch_tags: When true, the root git repo being checked out will not
    fetch any tags referenced from the references being fetched. When a repo
    has many references, it can become a performance bottleneck, so avoid
    tags if the checkout will not need them present.
  * disable_syntax_validation: (legacy) Disables syntax validation for DEPS.
    Needed as migration paths for recipes dealing with older revisions,
    such as bisect.
  * ignore_input_commit: if True, ignore api.buildbucket.gitiles_commit.
    Exists for historical reasons. Please do not use.
  * add_blamelists: if True, add blamelist pins for all of the repos that had
    revisions specified in the gclient config.
  * set_output_commit: if True, mark the checked out commit as the
    primary output commit of this build, i.e. call
    api.buildbucket.set_output_gitiles_commit.
    In case of multiple repos, the repo is the one specified in
    api.buildbucket.gitiles_commit or the first configured solution.
    When sorting builds by commit position, this commit will be used.
    Requires falsy ignore_input_commit.
  * step_test_data: a null function that returns test bot_update.py output.
    Use test_api.output_json to generate test data.
  * enforce_fetch: Enforce a new fetch to refresh the git cache, even if the
    solution revision passed in already exists in the current git cache.
  * assert_one_gerrit_change: if True, assert that there is at most one
    change in self.m.buildbucket.build.input.gerrit_changes, because
    bot_update module ONLY supports one change. Users may specify a change
    via tryserver.set_change() and explicitly set this flag False.

&mdash; **def [get\_project\_revision\_properties](/recipes/recipe_modules/bot_update/api.py#509)(self, project_name, gclient_config=None):**

Returns all property names used for storing the checked-out revision of
a given project.

Args:
  * project_name (str): The name of a checked-out project as deps path, e.g.
      src or src/v8.
  * gclient_config: The gclient configuration to use. If omitted, the current
      gclient configuration is used.

Returns (list of str): All properties that'll hold the checked-out revision
    of the given project. An empty list if no such properties exist.

&mdash; **def [resolve\_fixed\_revision](/recipes/recipe_modules/bot_update/api.py#460)(self, bot_update_json, name):**

Sets a fixed revision for a single dependency using project revision
properties.

Wrapper for easy calling of gclient steps.

&mdash; **def [break\_locks](/recipes/recipe_modules/gclient/api.py#291)(self):**

Returns local path to the repo where gerrit patch will be applied.

If there is no patch, returns None.
If patch is specified, but such repo is not found among configured solutions
or repo_path_map, returns name of the first solution. This is done solely
for backward compatibility with existing tests.
Please do not rely on this logic in new code.
Instead, properly map a repository to a local path using repo_path_map.
TODO(nodir): remove this. Update all recipe tests to specify a git_repo
matching the recipe.

Returns the merged got_revision_reverse_mapping.

Returns (dict): A mapping from property name -> project name. It merges the
    values of the deprecated got_revision_mapping and the new
    got_revision_reverse_mapping.

&mdash; **def [inject\_parent\_got\_revision](/recipes/recipe_modules/gclient/api.py#226)(self, gclient_config=None, override=False):**

Match gclient config to build revisions obtained from build_properties.

Args:
  gclient_config (gclient config object) - The config to manipulate. A value
    of None manipulates the module's built-in config (self.c).
  override (bool) - If True, will forcibly set revision and custom_vars
    even if the config already contains values for them.

&mdash; **def [resolve\_revision](/recipes/recipe_modules/gclient/api.py#161)(self, revision):**

&mdash; **def [runhooks](/recipes/recipe_modules/gclient/api.py#285)(self, args=None, name='runhooks', \*\*kwargs):**

&mdash; **def [set\_patch\_repo\_revision](/recipes/recipe_modules/gclient/api.py#371)(self, gclient_config=None):**

Updates config revision corresponding to patched project.

Useful for bot_update only, as this is the only consumer of gclient's config
revision map. This doesn't overwrite the revision if it was already set.

&emsp; **@spec_alias.deleter**<br>&mdash; **def [spec\_alias](/recipes/recipe_modules/gclient/api.py#129)(self):**

&mdash; **def [sync](/recipes/recipe_modules/gclient/api.py#166)(self, cfg, extra_sync_flags=None, \*\*kwargs):**

&mdash; **def [canonicalize\_repo\_url](/recipes/recipe_modules/gitiles/api.py#227)(self, repo_url):**

Returns a canonical form of repo_url. If not recognized, returns as is.
    

&mdash; **def [commit\_log](/recipes/recipe_modules/gitiles/api.py#121)(self, url, commit, step_name=None, attempts=None):**

Returns: (dict) the Gitiles commit log structure for a given commit.

&mdash; **def [download\_archive](/recipes/recipe_modules/gitiles/api.py#167)(self, repository_url, destination, revision='refs/heads/main'):**

Downloads an archive of the repo and extracts it to `destination`.

If the gitiles server attempts to provide a tarball with paths which escape
`destination`, this function will extract all valid files and then
raise StepFailure with an attribute `StepFailure.gitiles_skipped_files`
containing the names of the files that were skipped.

Args:
  * repository_url (str): Full URL to the repository
  * destination (Path): Local path to extract the archive to. Must not exist
    prior to this call.
  * revision (str): The ref or revision in the repo to download. Defaults to
    'refs/heads/main'.

&mdash; **def [download\_file](/recipes/recipe_modules/gitiles/api.py#137)(self, repository_url, file_path, branch='main', step_name=None, attempts=None, \*\*kwargs):**

Args:
  * url (str): URL of the remote repository.
  * ref (str): Name of the desired ref (see Gitiles.refs).
  * limit (int): Number of commits to limit the fetching to.
    Gitiles does not return all commits in one call; instead paging is
    used. 0 implies to return whatever first gerrit responds with.
    Otherwise, paging will be used to fetch at least this many
    commits, but all fetched commits will be returned.
  * cursor (str or None): The paging cursor used to fetch the next page.
  * step_name (str): Custom name for this step (optional).

Returns:
  A tuple of (commits, cursor).
  Commits are a list of commits (as Gitiles dict structure) in reverse
  chronological order. The number of commits may be higher than limit
  argument.
  Cursor can be used for subsequent calls to log for paging. If None,
  signals that there are no more commits to fetch.

A step to run arbitrary gsutil commands.

On LUCI this should automatically use the ambient task account credentials.
On Buildbot, this assumes that gsutil authentication environment variables
(AWS_CREDENTIAL_FILE and BOTO_CONFIG) are already set, though if you want to
set them to something else you can always do so using the env={} kwarg.

Note also that gsutil does its own wildcard processing, so wildcards are
valid in file-like portions of the cmd. See 'gsutil help wildcards'.

Args:
  * cmd (List[str|Path]) - Arguments to pass to gsutil. Include gsutil-level
      options first (see 'gsutil help options').

PYTHON_VERSION_COMPATIBILITY: PY2+3

The `osx_sdk` module provides safe functions to access a semi-hermetic
XCode installation.

Available only to Google-run bots.

#### **class [OSXSDKApi](/recipes/recipe_modules/osx_sdk/api.py#36)([RecipeApi][recipe_engine/wkt/RecipeApi]):**

API for using OS X SDK distributed via CIPD.

&emsp; **@contextmanager**<br>&mdash; **def [\_\_call\_\_](/recipes/recipe_modules/osx_sdk/api.py#62)(self, kind):**

Sets up the XCode SDK environment.

Is a no-op on non-mac platforms.

This will deploy the helper tool and the XCode.app bundle at
`[START_DIR]/cache/osx_sdk`.

To avoid machines rebuilding these on every run, set up a named cache in
your cr-buildbucket.cfg file like:

    caches: {
      # Cache for mac_toolchain tool and XCode.app
      name: "osx_sdk"
      path: "osx_sdk"
    }

If you have builders which e.g. use a non-current SDK, you can give them
a uniqely named cache:

    caches: {
      # Cache for N-1 version mac_toolchain tool and XCode.app
      name: "osx_sdk_old"
      path: "osx_sdk"
    }

Similarly, if you have mac and iOS builders you may want to distinguish the
cache name by adding '_ios' to it. However, if you're sharing the same bots
for both mac and iOS, consider having a single cache and just always
fetching the iOS version. This will lead to lower overall disk utilization
and should help to reduce cache thrashing.

Usage:
  with api.osx_sdk('mac'):
    # sdk with mac build bits

  with api.osx_sdk('ios'):
    # sdk with mac+iOS build bits

Args:
  kind ('mac'|'ios'): How the SDK should be configured. iOS includes the
    base XCode distribution, as well as the iOS simulators (which can be
    quite large).

Raises:
    StepFailure or InfraFailure.
