Migrating from 0.3.0 - in the trenches

[ajoslin103]

Thank You So Much for Asimov !! It's made a real difference in backups for years and years !!

Thank You So Much for taking over Asimov !! Now I get to go tell a lot of people it's been updated :)

I upgraded from 0.3.0 to 0.10.0 and hit some bumps -- here they are for your fun and edification

TLDR: uninstall 0.3.0 [completely*] first !! (including cached paths !! trash /Users/ajoslin/.cache/asimov)

The 0.10.0 Installation looked successful, but displayed an odd Warning

Anon23x:dist ajoslin$ brew install asimov
==> Auto-updating Homebrew...
[...]
==> Summary
🍺  /opt/homebrew/Cellar/asimov/0.10.0: 10 files, 90.9KB
==> Running `brew cleanup asimov`...
Disable this behaviour by setting `HOMEBREW_NO_INSTALL_CLEANUP=1`.
Hide these hints with `HOMEBREW_NO_ENV_HINTS=1` (see `man brew`).
Removing: /opt/homebrew/Cellar/asimov/0.3.0... (10 files, 17.7KB)
**Warning: Permission denied @ apply2files - /opt/homebrew/Cellar/asimov/0.3.0/bin/asimov**

So something in version 0.3.0 wouldn't let go...

The version 0.3.0 wouldn't easily remove brew remove asimov but brew told me how to sudo-force it which worked 👍

But which did NOT remove the previous .plist (since I forgot to stop the service => YMMV !!)

trash /Users/ajoslin/Library/LaunchAgents/homebrew.mxcl.asimov.plist

So then I installed and started asimov, but it wasn't running.... 🧐

Anon23x:ajoslin$   brew services start asimov
==> Successfully started `asimov` (label: homebrew.mxcl.asimov)
Anon23x:ajoslin$ ps aux | grep asimov
ajoslin          51276   0.0  0.0 435300352   1344 s000  S+    7:17PM   0:00.01 grep asimov
Anon23x:ajoslin$   brew services stop asimov

so I started it manually (as brew explains how to do) and it took issue w/my very ancient caches

Anon23x:ajoslin$   /opt/homebrew/opt/asimov/bin/asimov
cat: /Users/ajoslin/.cache/asimov/excluded: Permission denied

so I trashed those and it then started up just fine

Anon23x:ajoslin$ trash /Users/ajoslin/.cache/asimov
Anon23x:ajoslin$   /opt/homebrew/opt/asimov/bin/asimov

(trash* is a great command that "moves things to the trash" (way faster than rm -rf node_modules) so brew install trash and swamp out the place !!)

@ajoslin103 — shipped in v0.11.0, and thank you for writing this up in this much detail 🙏

The cat: ~/.cache/asimov/excluded: Permission denied was our bug, not your setup — your TLDR had the diagnosis right. If Asimov ever ran as root it left root-owned files in ~/.cache/asimov/, so every later run as you died on the first read with nothing but that one line. A cache is an optimisation; it should never be fatal. Both halves are fixed: the read degrades to a warning, and root runs no longer poison the cache.

One thing that isn't broken: Asimov is a one-shot scan, not a daemon. ps aux | grep asimov finding nothing after brew services start is expected — it scans, excludes, exits.

New, aimed at exactly your migration:

brew upgrade asimov && asimov doctor

It flags a shadowed /usr/local/bin/asimov, an orphaned homebrew.mxcl.asimov plist, a root-owned cache, and a bad config — read-only, printing fixes rather than running them. UPGRADING.md now has a v0.3.0 section in an order that works.

Closing as fixed. 🎉

Keeping open for others if they have the same issue. Thanks again.
