djblets.util.filesystem¶

Filesystem-related utilities.

is_exe_in_path(name: str) → bool¶

Checks whether an executable is in the user’s search path.

This expects a name without any system-specific executable extension. It will append the proper extension as necessary. For example, use “myapp” and not “myapp.exe”.

This will return True if the app is in the path, or False otherwise.

safe_join(base: str, *paths: str, path_mod: ~typing.Any = <module 'posixpath' (frozen)>, rel_to: ~typing.Optional[str] = None) → str¶

Safely join filesystem paths, ensuring the result is within a base path.

This will join paths and and ensure the resulting path doesn’t escape the base path, making it safer when including non-static path components.

The result is always an absolute path, unless rel_to is provided.

The implementation is based on Django’s internal django.utils._os.safe_join() function, with additional functionality, optimizations, and typing.

New in version 4.0.

Parameters:

• base (str) – The base path that the remaining paths will be joined to.

• paths (tuple of str) – The resulting paths to join.

• path_mod (module, optional) –

  An explicit path module to use.

  This is useful when building non-native filesystem paths.

• rel_to (str, optional) – A path that the result will be made relative to.

Returns:

The absolute joined path.

Return type:

str

Raises:

django.core.exceptions.SuspiciousFileOperation – The resulting path was outside of the base path.
