galaxy.tool_util.deps package

Dependency management for tools.

galaxy.tool_util.deps.build_dependency_manager(app_config_dict: Optional[Dict[str, Any]] = None, resolution_config_dict: Optional[Dict[str, Any]] = None, conf_file: Optional[str] = None, default_tool_dependency_dir: Optional[str] = None) → DependencyManager[source]

Build a DependencyManager object from app and/or resolution config.

If app_config_dict is specified, it should be application configuration information and configuration options are generally named to identify the context of dependency management (e.g. conda_prefix not prefix or use_cached_dependency_manager not cache). resolution_config_dict if specified is assumed to be the to_dict() version of a DependencyManager and should only contain dependency configuration options.

class galaxy.tool_util.deps.DependencyManager(default_base_path: str, conf_file: Optional[str] = None, app_config: Optional[Dict[str, Any]] = None)[source]

Bases: object

A DependencyManager attempts to resolve named and versioned dependencies by searching for them under a list of directories. Directories should be of the form:

$BASE/name/version/…

and should each contain a file ‘env.sh’ which can be sourced to make the dependency available in the current shell environment.

cached = False
__init__(default_base_path: str, conf_file: Optional[str] = None, app_config: Optional[Dict[str, Any]] = None) → None[source]

Create a new dependency manager looking for packages under the paths listed in base_paths. The default base path is app.config.tool_dependency_dir.

set_enabled_container_types(container_types_to_destinations)[source]

Set the union of all enabled container types.

get_destination_info_for_container_type(container_type, destination_id=None)[source]
property enabled_container_types

Returns the union of enabled container types.

get_resolver_option(resolver, key, explicit_resolver_options=None)[source]

Look in resolver-specific settings for option and then fallback to global settings.

get_app_option(key, default=None)[source]
property precache
dependency_shell_commands(requirements: ToolRequirements, **kwds: Any) → List[str][source]
requirements_to_dependencies(requirements, **kwds)[source]

class galaxy.tool_util.deps.CachedDependencyManager(default_base_path, **kwd)[source]

Bases: DependencyManager

cached = True
__init__(default_base_path, **kwd)[source]

Create a new dependency manager looking for packages under the paths listed in base_paths. The default base path is app.config.tool_dependency_dir.

build_cache(requirements, **kwds)[source]
dependency_shell_commands(requirements, **kwds)[source]

Runs a set of requirements through the dependency resolvers and returns a list of commands required to activate the dependencies. If dependencies are cacheable and the cache does not exist, will try to create it. If cached environment exists or is successfully created, will generate commands to activate it.

hash_dependencies(resolved_dependencies)[source]

Return hash for dependencies

get_hashed_dependencies_path(resolved_dependencies)[source]

Returns the path to the hashed dependencies directory (but does not evaluate whether the path exists).

Parameters

resolved_dependencies (list) – list of resolved dependencies

Returns

path

show_dependencies(tool_requirements_d, installed_tool_dependencies=None, **kwd)[source]

Resolves dependencies to build a requirements status in the admin panel/API

uninstall_dependencies(index=None, resolver_type=None, container_type=None, **payload)[source]

Attempt to uninstall requirements. Returns 0 if successfull, else None.

property unused_dependency_paths

List dependencies that are not currently installed.

remove_unused_dependency_paths(envs)[source]

Remove dependencies that are not currently used.

Returns a list of all environments that have been successfully removed.

install_dependencies(requirements, **kwds)[source]
install_dependency(index=None, **payload)[source]

Installs dependency using highest priority resolver that supports dependency installation (Currently only the conda resolver supports this). If index is given, attempt installation directly using the corresponding resolver. Returns True on success, False on failure. payload is dictionary that must container name, version and type, e.g. {‘name’: ‘numpy’, version=’1.9.1’, type=’package’}

property installable_resolvers

List index for all active resolvers that have the ‘install_dependency’ attribute.

property uninstallable_resolvers

List index for all active resolvers that can uninstall dependencies that have been installed through this resolver.

property tool_ids_by_requirements

Dictionary with requirements as keys, and tool_ids as values.
