rbtools.utils.filesystem¶

Functions

`chdir`(path)	Change to the specified directory for the duration of the context.
`cleanup_tempfiles`()
`get_config_paths`()	Return the paths to each `.reviewboardrc` influencing the cwd.
`get_home_path`()	Retrieve the homepath.
`is_exe_in_path`(name)	Return whether an executable is in the user's search path.
`iter_exes_in_path`(name)	Iterate through all executables with a name in the user's search path.
`load_config`()	Load configuration from .reviewboardrc files.
`make_empty_files`(files)	Creates each file in the given list and any intermediate directories.
`make_tempdir`([parent, track])	Create a temporary directory and return the path.
`make_tempfile`(*[, content, prefix, suffix, ...])	Create a temporary file and return the path.
`parse_config_file`(filename)	Parse a .reviewboardrc file.
`walk_parents`(path)	Walks up the tree to the root directory.

rbtools.utils.filesystem.is_exe_in_path(name: str) → bool[source]¶

Return 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”.

The result will be cached. Future lookups for the same executable will return the same value.

Changed in version 3.0: The result is now cached.

Parameters:: name (str) – The name of the executable.
Returns:: True if the executable is in the path. False if it is not.
Return type:: bool

rbtools.utils.filesystem.iter_exes_in_path(name: str) → Iterable[str][source]¶

Iterate through all executables with a name 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” or “myapp.cmd”. This will look for both variations.

Changed in version 4.0.1: On Windows, if not searching for a deliberate .exe or .cmd extension, this will now look for variations with both extensions.

New in version 4.0.

Parameters:: name (str) – The name of the executable.
Yields:: str – The location of an executable in the path.

rbtools.utils.filesystem.cleanup_tempfiles()[source]¶

rbtools.utils.filesystem.make_tempfile(*, content: Optional[bytes] = None, prefix: str = 'rbtools.', suffix: Optional[str] = None, filename: Optional[str] = None) → str[source]¶

Create a temporary file and return the path.

If not manually removed, then the resulting temp file will be removed when RBTools exits (or if cleanup_tempfiles() is called).

This can be given an explicit name for a temporary file, in which case the file will be created inside of a temporary directory (created with make_tempdir(). In this case, the parent directory will only be deleted when cleanup_tempfiles() is called.

Parameters:

content (bytes, optional) – The content for the text file.
prefix (str, optional) – The prefix for the temp filename. This defaults to rbtools..
suffix (str, optional) – The suffix for the temp filename.
filename (str, optional) – An explicit name of the file. If provided, this will override suffix and prefix.

Returns:

The temp file path.

Return type:

str

rbtools.utils.filesystem.make_tempdir(parent=None, track=True)[source]¶

Create a temporary directory and return the path.

By default, the path will be stored in a list for cleanup when calling cleanup_tempfiles().

Changed in version 3.0: Added track.

Parameters:

parent (unicode, optional) – An optional parent directory to create the path in.
track (bool, optional) –
Whether to track the directory for later cleanup.

New in version 3.0.

Returns:

The name of the new temporary directory.

Return type:

unicode

rbtools.utils.filesystem.make_empty_files(files)[source]¶: Creates each file in the given list and any intermediate directories.

rbtools.utils.filesystem.walk_parents(path)[source]¶: Walks up the tree to the root directory.

rbtools.utils.filesystem.get_home_path()[source]¶: Retrieve the homepath.

rbtools.utils.filesystem.get_config_paths()[source]¶

Return the paths to each .reviewboardrc influencing the cwd.

A list of paths to .reviewboardrc files will be returned, where each subsequent list entry should have lower precedence than the previous. i.e. configuration found in files further up the list will take precedence.

Configuration in the paths set in $RBTOOLS_CONFIG_PATH will take precedence over files found in the current working directory or its parents.

rbtools.utils.filesystem.parse_config_file(filename)[source]¶

Parse a .reviewboardrc file.

Returns a dictionary containing the configuration from the file.

The filename argument should contain a full path to a .reviewboardrc file.

rbtools.utils.filesystem.load_config()[source]¶

Load configuration from .reviewboardrc files.

This will read all of the .reviewboardrc files influencing the cwd and return a dictionary containing the configuration.

rbtools.utils.filesystem.chdir(path: str) → Generator[None, None, None][source]¶

Change to the specified directory for the duration of the context.

New in version 4.0.

Parameters:: path (str) – The path to change to.
Context:: Operations will run within the specified directory.
Raises:: FileNotFoundError – The provided path does not exist.
