cached plugin enum #768

jmartin-tech · 2024-07-01T23:43:11Z

Impacts of this change may be sufficient to close #663

First pass at building a local cache of plugin info to provide faster initial load of cli based runs.

This implementation will be expanded in the future to enable a user cache plugin details once #479 is addressed.

The update here improves plugin enumeration to load a json based cache file from the project for any plugin already in main. Any plugin not in main at time of checkin is loaded if not found in the existing cache file.

Tests have been added to document cache build process and validate that items not already in the cache will be loaded ephemerally at runtime if requested.

A future CI/CD action will maintain this cache file using a pattern like the following:

# remove the existing cache file
rm -rf garak/resources/plugin_cache.json
# Linux only command to ensure files are all timestamped to match last commit
git ls-files garak/ -z | xargs -0 -n1 -I{} -- git log -1 --format="%ai {}" {} | while read -r udate utime utz ufile ; do
  touch -d "$udate $utime" $ufile
done
# any `--list_*` command will build the cache when one is not found on disk
python -m garak --list_probes
# now just add the updated file in place of the existing version
git diff --exit-code garak/resources/plugin_cache.json
if [ ! $? ]; then
  echo "Plugin cache updates exist."
  git add garak/resources/plugin_cache.json
  git commit -S -m "update plugin_cache.json"
fi

generally good. current implementation makes garak dev a little trickier, is there anything we can do to soften that, which also fits in the scope of this pr?

Nice pattern. Should consider this in some other places (attempt.Attempt.as_dict springs to mind)

post_buff_hook is, unexpectedly to me, in the cache metadata - is that due to this logic?

The existing info included post_buff_hook:

main

We can further refine the info data to be provided in future iterations.

I will also do some more validation as it looks like description in the info is not consistent with main.

Ah nice. _post_buff_hook should def not be there. Some plugins change their descriptions during the constructor iirc.

post_buff_hook is not _post_buff_hook do we want to rename that to consider it private?

It looks like description is added in the base class constructor if not already provided in the class implementation for most of the plugins, this results in an inconsistency since the cache build actually avoids calling the constructors in this PR.

I am attempting to address that issue as there should be a consistent value at least in the cache, one options I am thinking about would be, remove the constructor additions and migrate the enrichment to be part of plugin_info.

+                    continue
+                plugin_metadata[v] = value


would like to see default params included here also. maybe something like this

Suggested change

plugin_metadata[v] = value

plugin_metadata[v] = value

plugin_metadata = plugin.DEFAULT_PARAMS | plugin_metadata

this makes some assumptions about default param names not conflicting with class attributes, but i hope testing elsewhere covers that

This might be something to consider doing in the display logic, not sure it needs to be in the json cache file in a specific format.

When done, is is possible to add a speed check test which, in addition to this, satisfies/describes #663 ?
