Using repodata_fns?

[bollwyvl]

Thanks for boa!

I've been investigating using it in more places, and have found there are a few performance issues. The first that jumped out at me was that it didn't recognize my repodata_fns setting (to get repodata.json.zst). This traceback (from cancelling during a slow download) shows the code path that's probably involved:

 /env/lib/python3.11/site-packages/boa/core/solver.py:127 in __init__

   124 │   │   self.output_folder = output_folder or "local"
   125 │   │   self.pool = libmambapy.Pool()
   126 │   │   self.repos = []
 ❱ 127 │   │   self.index = load_channels(
   128 │   │   │   self.pool, self.channels, self.repos, platform=platform
   129 │   │   )
   130

 /env/lib/python3.11/site-packages/mamba/utils.py:129 in load_channels

   126 │   use_cache=True,
   127 │   repodata_fn="repodata.json",
   128 ):
 ❱ 129 │   index = get_index(
   130 │   │   channel_urls=channels,
   131 │   │   prepend=prepend,
   132 │   │   platform=platform,

Not sure whether it's the job of boa or a mamba to get that value from the config, but it's definitely noticeable during builds with lots of solves and channels.

Thanks again!
