Story #8231
Updated by bmbouter almost 4 years ago
## Motivation
Pulp is duplicated the stdlib's tempfile module with its `from pulpcore.plugin.tasking.WorkingDirectory` facilities. In an effort to add, not duplicate value we should remove this so that plugins can use the [`tempfile` module](https://docs.python.org/3/library/tempfile.htm) directly.
## Recap of current functionality
The tasking system (with 3.10 at least) already creates a working directory in `/var/lib/pulp/cache/` and changes dir into it. It's namespaced by worker and task name so for example: ``. <--- put example here
## Plugin Experience
So plugins already have a working directory. If they need more they can create subdirectories using the tempfile facilities. Those would be nesteded in an area that is already theirs.
## Docs for plugin writers
Along with this story a new section should be added to the [plugin writers guide](https://docs.pulpproject.org/pulpcore/plugins/plugin-writer/concepts/index.html) called `Working Directories`. It should include docs that identify:
* that each task gets a clean, unique working directory, and it's set as the current working directory by the time their task code gets called
* If plugin writers need additional working directories, they should use the `tempfile` package to create more. These likely should be subdirectories of the one the tasking system provided for them.
* An example of creating a sub-dir of the working directory created by the tasking system.
