Hi all,
I recently received a warning from GitHub of the following:
********
Subject: Your total cache usage exceeds upcoming caching limits
Hello,
GitHub Actions is changing it’s cache policies beginning on October
15th, 2025. In the past, all repositories received a maximum 10GB of
cache. After this date, all repositories will receive 10GB for free and
have the option to pay for additional storage at a per GB/month rate
that is checked at hourly intervals.
You are receiving your email because your consumption exceeds 10GB
within a 24 hour period. As a result, you will need to do one of the
following:
Increase your cache retention past 10GB: This will have an
associated cost but you will keep all cache up to the limit you set.
Maintain your existing limit of 10GB: This will not occur
additional cost, but your least recently used cache will be evicted once
it reaches the 10GB limit
Modify caching practices: If you reduce what is cached, you will
not hit the limit
*******
I have been following the QGIS-PSC discussion about this:
https://lists.osgeo.org/pipermail/qgis-psc/2025-September/010649.html
I have checked the GitHub Actions cache section of the MapServer repo,
and I see several >=1GB entries, some from even 3 weeks ago, still in
our cache for "micromamba-environment" (from I believe our Conda builds).
(now to be very honest, I think the above "Your total cache usage
exceeds" message was sent to my @jmckenna GitHub account, likely
regarding my own cache in my jmckenna account, not specifically for
github.com/MapServer/MapServer but I think it's good to make others
aware of this in the MapServer PSC)
I see that we can add a custom action to delete older cache after X days
etc. but I haven't experimented with that yet.
Thoughts?
(I have also added this to the PSC meeting agenda)
thanks,
-jeff
